REMOVABLE COVER FOR PURPOSE

专利摘要:
removable cover is a removable cover for an object that includes an adhered section that is adhered to the object (for example, adhered to an object receiving surface through an adhesive layer) and a free section that is not adhered to the object . the removable cover is flexible enough to allow at least partial removal of the adhered section of the object by applying a force to the release cover. typically, the removable cover is adhered to the object such that resistance to removal of the cover from the object varies at different attachment zones between the removable cover and the object. variation in strength can be achieved, for example, by employing flaps, loops, folds, adhesive strips of varying strength, textures and/or release coatings. exemplary packaging systems (eg, containing removable covers and/or objects) include features such that the packaging system's resistance to removal from an object varies at different stages of removal.

CROSS REFERENCE TO PRIORITY REQUESTS
[0001] This international application here claims the benefit of US Patent Application No. 61/549,317 for a "Protective Covering for Adhesive Backed Articles and Methods of Applying the Same" (filed October 20, 2011), US Patent Application No. 61/561,522 for a “Protective Packaging for Adhesive Backed Articles” (filed November 18, 2011) and Patent Application No. US 61/654,748 for a “Removable Covering and Interactive Packaging” (filed June 1, 2012) , each of which is fully incorporated by reference. FIELD OF THE INVENTION
[0002] The invention refers to the field of protective layers (for example, bandages, thin films, sheets, tapes) that are placed on another object, which includes the human body and, adhered to it, at least temporarily, through a sticker. BACKGROUND
[0003] In manufacturing, construction, medicine and other fields, there is a frequent requirement to provide a protective barrier on the surface of an object to prevent damage or trauma, exposure (eg to air to prevent oxidation), contamination (eg , by infectious agents or contaminants carried by the hand) or premature interaction (eg, adhesion to an unintended object or with unwanted alignment). In addition, protective barriers can help to align, secure, adhere or otherwise control an interface between two surfaces. Examples would include applying laminates or plywood to cover a base structure, tile or insulating layers for a building feature, a protective layer over detector electronics, or applying elastic bandages. A removable cover can, by itself, support an adhesive layer as a means of temporary attachment to a non-adhesive support device. In applications where the protected object itself exhibits an adhesive layer that is intended to adhere the object to another surface, the removable covering is placed over the adhesive layer and removed as part of the application process. In general, the sticky object needs to be turned and rotated out of the intended application orientation for the coating to be removed. The subsequent need to align the unprotected adhesive surface can lead to poor positioning or misapplication. The process of covering the exposure for removal can prevent effective placement and/or alignment of surfaces to be bonded. Several examples can illustrate the potential problems with such a maneuver.
[0004] When applying adhesive bandages, the underside (adhesive surface) of the bandage must be turned upwards, so that the support handle flaps, normally close to the center (cushion) of the bandage, can be accessed or viewed . As the covering is removed, the bandage must then be rotated 180 degrees again so that the underside can be applied to the skin and, during this reorientation, an inadvertent adhesion of one portion of the bandage to another can occur, which , therefore, potentially makes the bandage unusable. If, during application, the covering is initially only partially removed, the bandage must be rotated without inadvertently removing the remaining links, which thus again potentially allows elements of the bandage to adhere to other parts of the bandage and render the bandage unusable or for potentially contaminating the bandage. If the covering is removed completely before application, this requires the adhesive surfaces to be gripped by the fingers and risks of contamination of the central pad of the bandage or poor adherence of the adhesive zone that was previously taken up prior to bonding to the wound site. Gripping and releasing the bandage on the adhesive surface is particularly difficult when the wearer is wearing gloves. If the user wishes to apply the bandage under tension in order to create a tensile strength within the bandage prior to application, this requires the entire bandage coverage to be removed and the adhesive surfaces to be caught in the users' hands, which again potentially affects the sterility or adhesion of the device. In addition, removing the dressing can be a challenge for patients with limited dexterity, for example, in the case of severe arthritis or where one of the hands may have impaired function due to an injury. In such cases, removal of the bandage wrap represents an additional step in preparing and positioning the bandage.
[0005] Another example that represents the potential problems involved when removing a covering can be illustrated in the adhering of decorative coverings or devices to a flat surface, regardless of whether these coverings are inflexible (eg plywood) or flexible (eg sheets elastic or woven). When the decorative coverings or devices are inflexible, the adhesive layer on the decorative covering or the device must be exposed without the adhering surfaces already in alignment, depending on the devices to be adhered to each other (for example, a decorative covering and a surface ) are brought into close proximity, it is very easy to have the surfaces inadvertently adhered in a misaligned orientation. In this case, removal and positioning of the decorative covering or device is necessary and, in cases where the adhesion strength is large due to either the large surface areas adhered or the inherent strength of the adhesive, this can lead to damage to a or to both bonded surfaces. If the decorative coating is flexible, this same alignment problem after removal of the coating is encountered and, in addition, creases can be created during application that may not be correctable, damage can occur to any of the adhered surfaces.
[0006] Although many other examples exist, it is noted that a covering or covering device (eg, a protective covering) that can assist in the alignment and placement of a device to be adhered to another surface is desirable. Similarly, the combination of such a cover device and integrated packaging can help control the position, orientation, application and use of devices, without the direct handle of the device itself, and can aid in the removal of the support. In both of these types of use, if packaging devices are configured to function either as an integrated part of a covering device or to facilitate the application of said covering device, this can lead to reduced materials and waste and improved ease of use. . SUMMARY
[0007] In one aspect, the present invention encompasses a substantially flat removable cover for an object. The removable cover typically includes a first free section that is not bonded to the object, a first bonded section that is bonded to the object, and a second bonded section that is bonded to the object. The first bonded section and the second bonded section may be connected to opposite ends of the first free section. The removable cover is normally flexible enough to allow at least partial removal of the first adhered section of the object by applying a force to the release cover.
[0008] In an exemplary embodiment, the force required to remove the removable cover from the object varies in different attachment zones between a removable cover and the object.
[0009] In another exemplary embodiment, the removable cover is adhered to the object so that the resistance to removal of the removable cover from the object varies in different attachment zones between a removable cover and the object.
[0010] In another aspect, the present invention encompasses a substantially flat removable cover for an object that includes a first adhered section that is adhered to the object, a flap section that is not adhered to the object, a first free section that is not adhered to the object to the object and a second free section that is not adhered to the object. Typically, the first free section and the second free section are connected to opposite ends of the first bonded section and to the same end of the flap section. The removable cover is normally flexible enough to allow at least partial removal of the first adhered section of the object by applying a force to the release cover.
[0011] In an exemplary embodiment, the force required to remove the removable cover from the object varies in different attachment zones between the removable cover and the object.
[0012] In another exemplary embodiment, a removable cover is adhered to the object so that the resistance to removal of the removable cover from the object varies in different attachment zones between the removable cover and the object.
[0013] In yet another aspect, the present invention encompasses a packaging system for an object and a removable cover that interacts with the removable cover (for example, through adhesive layers or a constriction mechanism) to facilitate the application of the object . Typically, the packaging system can be removed from the object by applying forces in opposite directions to opposite ends of the packaging system.
[0014] In an exemplary embodiment, the packaging system interacts with the removable cover so that the removable cover is removed from the object at the same time as the packaging system is removed from the object.
[0015] In another exemplary embodiment, the packaging system includes visible figurative elements that are related in such a way as to convey a story of how the packaging system is removed from the object.
[0016] In another exemplary embodiment, the packaging system includes visible figurative elements that present a message or information of how the packaging system is removed from the object.

[00173] In one aspect, the present invention encompasses a removable cover (eg a support or support device) for a receiving surface (eg an object having an adhesive layer). The removable cover facilitates the positioning, orientation, application and use of the receiving surface, as well as the removal of the removable cover.
[00174] In particular, the invention relates to removable covers that peel off from objects (eg, protected devices) to expose an adhesive that can then be applied to a receiving surface that is covered by the object on application. In a particular embodiment, the invention relates to the construction of the removable cover and the level of resistance to peeling that the construction of the removable cover brings to the object. Peel strength can be varied along the peel path to allow proper placement of the release liner on the receiving surface prior to final application of the entire liner. Typically, the removable cover comprises a material of sufficient flexibility to permit at least partial removal of a protected device or object by applying a peel force vector applied to a section or structural feature of the removable cover (e.g., support).
[00175] As described in this document, protected devices and/or objects are normally, substantially flat, rectangular in shape, and symmetrical. That said, exemplary embodiments of the present invention may include objects, removable covers and packaging systems that are not flat, rectangular or symmetrical. For example, a circular-shaped object, a removable cover and/or packaging system is within the scope of the present invention. Furthermore, for particularly long objects (for example, which have lengths significantly greater than widths), the removable covers and/or packaging systems can be removed in a direction parallel to the width of the object, rather than the length as disclosed herein. .
[00176] The disclosure of this invention includes the use of numerous mechanisms to change the peel force resistance of the removable cover attached to a protective layer to be applied to a receiving surface. Each of these mechanisms is conducive to mixing and interchangeable in any given device. The construction of the removable cover is disclosed with certain portions shown as a continuous layer, but such disclosure is not limiting of the invention. The invention encompasses embodiments in which any layer comprises multiple portions. This disclosure often refers to an adhesive layer from which the removable cover is peeled off. The adhesive layer may peel off while remaining on the release layer (i.e., leaving the receiving surface free of adhesive) or the release covering may peel off and leave the adhesive layer on the receiving surface.
[00177] Aspects of exemplary removable covers and packaging systems are described herein with reference to the numerous Figures. In the description, a single side of a removable cover or packaging system can be described (for example, only the left side or the right side). The removable cover or packaging system typically includes left and right sides that are mirror images of each other (that is, the left and right sides have the same components), unless otherwise noted. Therefore, the description of a single side of a removable cover or packaging system can be applied equally to the other side. That said, it is within the scope of the present invention to employ single-sided removable covers and/or packaging systems.
[00178] Furthermore, aspects of exemplary removable covers and packaging systems are described herein with reference to the removal steps. As will be recognized, these removal phases generally correspond to attachment zones between the removable cover and the object.
[00179] Figure 1 depicts a side view of an exemplary removable cover 1001 and an object 1003 that has a receiving surface 1002. Each side (i.e., the left and right sides) of the exemplary removable cover 1001 includes a primary flap 1004 (eg, a center end or free section), a side free section 1008, and a secondary flap 1007 (e.g., a side end or free section) that are not adhered to the receiving surface 1002 of the object 1003. The removable cover 1001 it also includes a center section 1005 (eg a bonded section) and a side section 1006 (eg a bonded section) that are bonded to the receiving surface 1002.
[00180] Figure 2 depicts a side view of another exemplary removable cover where the receiving surface 1002 is an adhesive layer. In this regard, adhesive layer 1002, which may be on object 1003 or removable cover 1001, is positioned between removable cover 1001 and object 1003. Figures 3 to 6 depict side views of exemplary removable cover 1001 and object 1003 at different stages of removal, while Figure 7 graphically depicts the application force or resistance required to remove the exemplary removable cover 1001 from object 1003 as a function of time. In Figure 7, "Phase 0" corresponds to Figures 1 and 2; "Phase 1" corresponds to Figure 3; "Phase 1B" corresponds to Figure 4; "Phase 2" corresponds to Figure 5; and "Phase 3" corresponds to Figure 6.
[00181] Figure 8 depicts a perspective view of the exemplary removable cover 1001, receiving surface 1002, object 1003 of Figures 1 and 2 (i.e., Stage 0). Figure 9 depicts a perspective view of the exemplary removable cover 1001, receiving surface 1002, and object 1003 of Figures 1 and 2 in the same removal stage as shown in Figure 4 (i.e., Stage 1B). Figure 10 depicts a perspective view of the exemplary removable cover 1001, receiving surface 1002, and object 1003 of Figures 1 and 2 in the same removal stage as shown in Figure 6 (i.e., Stage 3).
[00182] In this exemplary modality, Phase 0 is followed by the capture of a primary flap 1004 that requires the application of an intermediate line separation force. Phase 1 requires a force to overcome a 180 degree peel force resistance. Phase 1B may require a force to overcome a 180 degree peel force resistance (for example, if lateral free section 1008 is adhered to secondary tab 1007) or no force (for example, if lateral free section 1008 is not adhered to secondary flap 1007). During Phase 2, there is a resistance to shear removal, however, the secondary flap 1007 is exposed. See, for example, Figure 5. In this way, secondary tab 1007 can be pulled during Phase 3 to overcome a second 180 degree peel force resistance.
[00183] In that regard, exemplary embodiments of the present invention encompass a removable cover constructed and oriented such that, when applied to a receiving surface, said removable cover exhibits a fold such that portions of both flat surfaces of the cover removable surface are adhered to different sections of the receiving surface. A center end does not adhere to the receiving surface and acts as a primary flap to peel a center section of the removable cover from the receiving surface at a peel angle that is between 90 and 180 degrees. Upon completion of the 90 to 180 degree peel with the same force vector, the peel angle transitions to a 0 degree peel angle (shear) with greater peel strength within a side section that is continuous with the center section . A second embodiment incorporates a secondary flap continuous with the side section and not adhered to the receiving surface to allow a secondary peel angle of between 90 and 180 degrees to be applied to the side section.
[00184] Figure 11 depicts a side view of an exemplary removable cover 1011 and an object 1013 that has a receiving surface 1012. Each side (i.e., the left and right sides) of the exemplary removable cover 1011 includes a primary tab 1014 (e.g., a center terminal or free section), a first free section 1017, a flap section 1018, and a second free section 1019 that are not adhered to the receiving surface 1012 of the object 1013. The removable cover 1011 also includes a central section 1015 (e.g., a bonded section) and a side section 1016 (e.g., a first bonded section) which are bonded to the receiving surface 1012.
[00185] As shown, first free section 1017 and second free section 1019 are connected to opposite ends of side section 1016. Additionally, first free section 1017 and second free section 1019 are connected to the same end as tab section 1018. aspect, the first free section 1017, the second free section 1019, and the last section 1016 form a loop connected to the tab section 1018.
[00186] Figures 12 to 15 depict the side views of the exemplary removable cover 1011 and object 1013 at different stages of removal, while Figure 16 graphically depicts the application force or resistance required to remove the exemplary removable cover 1011 from object 1013 as a function of time. In Figure 16, "Phase 0" corresponds to Figure 11; "Phase 1" corresponds to Figures 12 and 13; "Phase 2" corresponds to Figure 14; and "Phase 3" corresponds to Figure 15.
[00187] Figure 17 depicts a perspective view of exemplary removable cover 1011, receiving surface 1012, and object 1013 of Figure 11 (i.e., Stage 0). Figure 18 depicts a perspective view of the exemplary removable cover 1011, receiving surface 1012, and object 1013 of Figure 1 in the same removal step as shown in Figure 14 (i.e., Step 2).
[00188] In this exemplary modality, Phase 0 is followed by the capture of a primary tab 1014 that requires the application of an intermediate line separation force. Phase 1 requires a force to overcome a 180 degree peel force resistance. The anterior portion of Phase 2 (ie, the alternation from a 180 degree peel strength resistance to a shear peel strength) occurs after reaching the orientation shown in Figure 14. The last portion of Phase 2 (ie. ie, the shear platform) occurs when the pulling force is primarily lateral. During Phase 3, the loop releases from the receiving surface 1012.
[00189] In such exemplary removable covers including a loop, the degree of transfer between 180 degree peel strength and shear peel strength can be adjusted by varying the junction point of the flap section 1018 and Hello co. For example, if the first free section 1017 is closest to the outer edge of the receiving surface 1012 (i.e., the tab section 1018 connects to the loop farthest from the center of the receiving surface), the peel strength will alternate from 180 degree peel strength resistance to faster shear peel strength resistance. In other words, the drop in the strength/endurance curve in the earlier portion of Phase 2 in Figure 16 will be greater (ie, a steep drop).
[00190] In this regard, the exemplary embodiments of the present invention encompass a removable cover constructed and oriented so that, when applied to a receiving surface, said removable cover displays a side section that defines a loop, so that portions of both the flat surfaces of the removable cover are adhered to different sections of the receiving surface. The side section is continuous with a center section along the non-adhered surface of the side section. The connection between the side and center sections can be in any position along the length of the side section. A center end does not adhere to the receiving surface and acts as a primary flap to peel a center section of the removable cover from the receiving surface at a peel angle that is between 90 and 180 degrees. Upon completion of the 90 to 180 degree peel with the same force vector, the peel angle transitions to at least a partial 0 degree peel angle (shear) with greater peel strength within a side section that is continuous with the center section. With an increasing force vector and no change in direction, the peel strength is overcome, and the coating is removed from the receiving surface.
[00191] Figure 19 depicts a side view of two exemplary removable covers 1021A and 1021B and an object 1023 that has a receiving surface 1022 and a center feature 1025 (e.g., an absorbent pad or non-adhesive surface). Removable left cover 1021A includes a flap section 1028A, a first free section 1027A, and a second free section 1029A that are not adhered to receiving surface 1022 of object 1023. Removable left cover 1021A also includes a side section 1026 A which is adhered to the receiving surface 1022 and covers at least a portion of the center feature 1025.
[00192] The right-hand removable cover 1021B includes a flap section 1028B, a first free section 1027B, and a second free section 1029B, which are not adhered to the receiving surface 1022 of the object 1023. The right-hand removable cover 1021B also includes a side section 1026B that is adhered to the receiving surface 1022. Additionally, the removable right cover 1021B includes a center flap 1024B that is adhered to the receiving surface 1022 and covers at least a portion of the center feature 1025.
[00193] As shown with respect to the left removable cover 1021A, the first free section 1027A, the second free section 1029A, and the side section 1026A are connected to form a loop that is further connected to the tab section 1028A.
[00194] As shown with respect to the right-hand removable cover 1021B, the first free section 1027B, the second free section 1029B, and the side section 1026B are connected to form a loop that is further connected to the tab section 1028B. The loop is also connected to the 1024B center flap.
[00195] The flap sections 1028A and 1028B of the removable covers 1021A and 1021B are connected to their respective loops at different locations.
[00196] Figures 20 to 22 depict perspective views of the two exemplary removable covers 1021A and 1021B at different stages of removal. As shown, the tab section connection point 1028A and 1028B of the removable covers 1021A and 1021B alters the removal process and changes the strength in each of the removal phases.
[00197] In this regard, the exemplary embodiments of the present invention encompass a removable cover in which the length of the loop can be varied to change the point on the side section at which the peel strength approaches a shear force at which point a section unadhered center (eg, center flap 1024B) becomes a flap for a secondary force vector to provide a peel angle that is between 90 and 180 degrees.
[00198] Figure 23 depicts a side view of an exemplary removable cover 1031 and an object 1033 that includes a receiving surface 1032. Each side (i.e., the left and right sides) of the exemplary removable cover 1031 has the same components. Exemplary removable cover 1031 includes a side support section 1034 and a center support section 1035. The center support section 1035 includes a center flap 1035A that is not adhered to the receiving surface 1032 and a first adhered section 1035B that is adhered to the receiving surface 1032.
[00199] The side support section 1034 includes a first free section 1036, a second free section 1038, and a connecting section 1039 that are not adhered to the receiving surface 1032. The side support section 1034 also includes a first adhered section 1037 which is adhered to the receiving surface 1032. As shown, the lateral support section 1034 wraps around the outer edge of the object 1033.
[00200] Figure 24 depicts a side view of the exemplary removable cover 1031 and object 1033 of Figure 23 within an exemplary packaging system 2000. Packaging system 2000 includes two pieces, a left sleeve 2000A and a right sleeve 2000B, which they may or may not be joined by an adhesive layer 2001. Gloves 2000A and 2000B each include an upper 2003A and 2003B and a lower 2002A and 2002B, respectively.
[00201] Exemplary removable cover 1031 and packaging system 2000 work together to facilitate the insertion of object 1033 and its receiving surface 1032. In this regard, each connecting section 1039 of the support section (i.e., in the left portions and right of the removable cover 1031) is typically adhered to each respective upper 2003A or 2003B of the packaging system 2000. Additionally, each center flap of the central support section 1035A (i.e., on the left and right portions of the removable cover 1031) is typically adhered to each respective lower 2002A or 2002B of packaging system 2000.
[00202] Figures 25 and 26 depict side views of the exemplary removable cover 1031, object 1033, and packaging system 2000 of Figure 24 at different stages of removal. As shown in Figure 25, when a user pulls the left and right sleeves 2000A and 2000B apart, the removable cover 1031 is also removed. Initially, there is a 180 degree peel force resistance as the first bonded section 1035B of the center support section is removed from the receiving surface 1032. At some point during the removal process, the side support section 1034 will become fully extended (See Figure 26) and there will be a resistance to shear peel force. To complete the removal process, the first free section 1036 of the side bearing section can be engaged by a force that overcomes a 180 degree peel force resistance.
[00203] Figure 27 depicts a perspective view of the exemplary removable cover 1031, object 1033, and packaging system 2000 of Figure 24. Figure 28 depicts a perspective view of the exemplary removable cover 1031, object 1033, and packaging system 2000 in the same removal phase as shown in Figure 26.
[00204] Figure 29 depicts a side view of an exemplary removable cover 1031 and object 1033 within an exemplary packaging system 2000. The primary differences between the exemplary removable cover 1031 of Figure 29 and that of Figures 23 to 26 are the locations of attachment of the exemplary removable cover 1031 to (i) the object 1033 and (ii) the packaging system 2000. In Figure 29, the first adhered section 1037 of the lateral support section is adhered to the upper surface of the object 1033 (for example, through an adhesive layer) rather than the receiving surface 1032 as in Figures 23 to 26. Additionally, each connecting section of the support section 1039 (i.e., on the left and right portions of the removable cover 1031) is adhered to each part. respective top 2003A or 2003B at a location that is closer to the central portion of the packaging system 2000 than in Figures 23 to 26.
[00205] Figures 30 to 31 depict side views of the exemplary removable cover 1031, object 1033, and exemplary packaging system 2000 of Figure 29 at different stages of removal. As shown in Figure 30, when a user pulls the left and right sleeves 2000A and 2000B apart, the removable cover 1031 is also removed. Initially, there is a 180 degree peel force resistance as the first bonded section 1035B of the center support section is removed from the receiving surface 1032. At some point during the removal process, the side support section 1034 will become fully extended (See Figure 31) and there will be a resistance to the shear peel force. To complete the removal process, the first free section 1036 of the side bearing section can be engaged by a force that overcomes a 180 degree peel force resistance. As compared to Figures 23 to 26, however, the exemplary embodiment shown in Figures 29 to 31 includes a first free section 1036 that can be engaged while the receiving surface 1032 has been placed, due to the fact that the first free section 1036 is in place. at the top of object 1033.
[00206] In this regard, exemplary embodiments of the present invention encompass a removable covering that provides a change in resistance to covering removal along a vector force by means of separate non-contiguous sections of the removable covering applied to different zones of a surface of primary or secondary reception. By separating the package, the user peels off a central section at a peel angle that is between 90 and 180 degrees. A side section applied to both a primary and secondary receiving surface is subjected to a shear force that creates increased peel strength compared to the center section. The side section can be removed by means of a secondary flap (eg a first free section) that is not adhered to the primary or secondary receiving surface.
[00207] The exemplary removable covers depicted and described in relation to Figures 23 to 31 employ free sections, bonded sections, and flaps, but may also include loops as depicted and described in relation to Figures 11 to 22.
[00208] Furthermore, all exemplary removable covers may include zones of altered adhesive strength. For example, Figure 32 depicts a side view of an exemplary removable cover 1031 and object 1033 within an exemplary packaging system 2000. The exemplary removable cover 1031 and packaging system 2000 of Figure 32 are similar to those of Figures 29 to 31, however, the 1031 removable cover does not include a side support section. Additionally, the exemplary removable cover a includes a central tab 1035A that is not adhered to receiving surface 1032 and a first adhered section 1035B that is adhered to receiving surface 1032, but also includes a second adhered section 1035C and a third adhered section 1035D . Second bonded section 1035C is bonded to an extra adhesive layer 1040 that is bonded to receiving surface 1032. Third bonded section 1035D is bonded to receiving surface 1032. Second bonded section 1035C and extra adhesive layer 1040 increase resistance to detachment force during removal. The third bonded section 1035D provides a reduction in resistance to peel force in the last phase of removal.
[00209] The extra adhesive layer 1040 may be part of the removable cover 1031 or the receiving surface 1032. Alternatively, instead of having an extra adhesive layer 1040 in the position shown, a different adhesive force could be used in the position shown to increase or decrease the resistance to the detachment force.
[00210] As shown in Figure 32, a central adhesive layer 2005 can adhere the left and right sides of the removable cover 1031 to each other. The central adhesive layer 2005 can provide increased protection against contamination of or damage to the receiving surface 1032 (eg, an adhesive layer).
[00211] Figure 33 depicts a side view of an exemplary removable cover 1031 and object 1033 within an exemplary packaging system 2000. The exemplary removable cover 1031 of Figure 33 is similar to that of Figure 32, but the removable cover 1031 does not include a third section 1035D adhered to the outer edge of the receiving surface. In this regard, the second bonded section 1035C and the extra adhesive layer 1040 increase the resistance to peel force during stripping during the last stripping phase.
[00212] In this regard, exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a vector force by means of a change in adhesive strength between the removable cover and the receiving surface to which it is turned on. Adhesive strength can be adjusted in zones of varying adhesive strength.
[00213] Figure 34 depicts a perspective view of an exemplary object 1003, adhesive layer 1002, and two exemplary removable covers 1001A and 1001B. Exemplary removable covers 1001A and 1001B each include a primary flap 1004 (e.g., a center terminal or free section) and a center section 1005.
[00214] Legend 3001 shows a pattern that identifies an area of low resistance to peel strength. Legend 3002 shows a pattern that identifies an area of average resistance to peel strength. Legend 3003 shows a pattern that identifies an area of high resistance to peel strength. These peel strength strengths can be achieved by varying the texture or surface of the side of the center section facing adhesive layer 1002.
[00215] Consequently, as the removable cover 1001A is removed by pulling the primary tab 1004, initially there is a low resistance to peel force, followed by a medium resistance to peel force, and finally a high resistance to peel force. detachment. In other words, an increasingly greater force is required to remove the removable cover 1001A during the removal process.
[00216] As the removable cover 1001B is removed by pulling the primary flap 1004, initially there is a high resistance to peel force, followed by a low resistance to peel force, then a medium resistance to peel force, then a high peel strength, and finally a low peel strength.
[00217] In this regard, exemplary embodiments of the present invention encompass a cover that provides a change in resistance to cover removal along a vector force by means of a change in surface texture characteristics of the removable cover along the zones in the which it is attached to the receiving surface. Typically, coarser textured areas are less tacky, and smoother areas are more tacky.
[00218] Figure 35 depicts an exemplary removable cover 1041 and object 1043 that includes a receiving surface 1042 (eg, an adhesive layer). Removable cover 1041 includes a primary tab 1044 (e.g., a center terminal or free section), a first free section 1046, and a second free section 1048 (e.g., a secondary tab) that are not adhered to the receiving surface 1042 or to object 1043. Removable cover 1041 also includes a first adhered section 1045 (e.g., a side section) that is adhered to receiving surface 1042 and a second adhered section 1047 that is adhered to the upper surface of object 1043 (e.g. through an adhesive layer 1050).
[00219] Figures 36 to 38 depict the side views of the exemplary removable cover 1041 and object 1043 at different stages of removal, while Figure 39 graphically depicts the application force or resistance required to remove the exemplary removable cover 1041 from the object 1043 as a function of time. In Figure 39, "Phase 0" corresponds to Figure 35; "Phase 1" corresponds to Figure 36; "Phase 2" corresponds to Figure 37; and "Phase 3" corresponds to Figure 38.
[00220] In this regard, the exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a force vector by means of an extension that interfaces with more than one surface of the receiving surface turned on. A center section includes a tab that is non-gripped and is available to peel off the center section at a peel angle between 90 and 180 degrees. A side section is contiguous with the center section and is bonded to a secondary receiving surface that exhibits a shear strength to the same force vector that peeled off the center section. The side section may exhibit a secondary tab that is not adhered to the secondary receiving surface so that the side section peels off at an angle of between 90 and 180 degrees.
[00221] Figure 40 depicts a side view of an exemplary removable cover 1051 and object 1053, and Figure 41 depicts a side view of an exemplary removable cover 1051 of Figure 40 positioned on object 1053. Object 1053 includes a receiving surface 1052 (for example, an adhesive layer). Each side (i.e., the left and right sides) of the exemplary removable cover 1051 has the same components. Removable cover 1051 includes a side support section 1054 and a center support section 1055. The center support section 1055 includes a center flap 1055A that is not adhered to the receiving surface 1052 and a first adhered section 1055B that is adhered to the receiving surface 1052.
[00222] The side support section 1054 includes a first free section 1056 (e.g., a secondary tab) and a second free section 1058 that is not adhered to the receiving surface 1052. The side support section 1054 also includes a first section adhered to 1057 which is adhered to the first adhered section of the central bearing section 1055B (e.g. through an adhesive layer 1050) and a second adhered section 1059 which is adhered to the upper surface of the object 1053 (e.g. through an adhesive layer 1050). As shown, side support section 1054 wraps around the outer edge of object 1053.
[00223] Figure 42 depicts a side view of an exemplary removable cover 1061 and object 1063. Each side (i.e., the left and right sides) of the exemplary removable cover 1061 has the same components. Exemplary removable cover 1061 includes an adhesive layer 1060. Exemplary removable cover 1061 also includes a first bonded section 1066, a second bonded section 1067, and a third bonded section 1068 that adhere to object 1063 through adhesive layer 1060. See Figure 44 Additionally, exemplary removable cover 1061 includes a first free section 1065 and a second free section 1069. As shown in Figure 43, the first free section 1065 and the second free section 1069 can be folded or rolled onto the adhesive layer 1060 to create the tabs. By folding the first free section 1065 and the second free section 1069 into the adhesive layer 1060, when the exemplary peel-off cover 1061 is applied to the object 1063, the first free section 1065 and the second free section 1069 are not adhered to the object 1063. See a Figure 44. As shown in Figure 44, the removable cover 1061 can protect the object 1063 until it needs to be placed on a surface.
[00224] For example, Figure 45 depicts a side view of the exemplary removable cover 1061 and object 1063 of Figures 42 to 44 as applied to a surface 1062. Starting with the configuration shown in Figure 44, the first free section 1065 from the side The left and right sides of the removable cover 1061 can be captured and pulled to remove the first adhered section 1066 from the bottom surface of object 1063. The bottom surface of object 1063 can then be placed on surface 1062. To hold or secure object 1063 to the surface 1062 (e.g., to allow an adhesive, such as glue or cement, to dry or harden), first adhered section 1066 may be adhered to the portion of surface 1062 adjacent to object 1063 (e.g., through adhesive layer 1060).
[00225] In exemplary embodiments, the removable cover 1061 may include markings (e.g., grid lines, directives and/or alignment markings) that facilitate the application or placement of object 1603 on surface 1062. Markings may be stamped on the outer surface of removable cover 1061 (i.e., on the surface that does not face the object 1063). Although described in relation to the exemplary embodiment of Figure 45, such markings may be included on any of the exemplary removable covers and/or objects disclosed herein. Typically, the markings are stamped onto a peel-off surface that is visible from above the peel-off during the removal process. In this sense, markings can facilitate the user's alignment of the removable cover and/or the object on a surface during the removal process by providing visual guidance.
[00226] Thus, exemplary embodiments of the present invention encompass a removable cover that includes a side section and a center section that can be made of one or more than one component. As shown, when the center section of the release cover (on the primary receiving surface) includes a respective adhesive layer, that same adhesive layer (removed with a 90 to 180 degree peel) can again be adhered to a tertiary receiving surface.
[00227] Figure 46 depicts a side view of an exemplary removable cover 1071 and object 1073 that includes a receiving surface 1072 (eg, an adhesive layer) and a central pad 1070. Each side (i.e., the left side and right) of the exemplary removable cover 1071 has the same components. Removable cover 1071 includes a side support section 1074 and a center support section 1075. The center support section 1075 includes a center flap 1075A that is not adhered to the receiving surface 1072 and a first adhered section 1075B that is adhered to the receiving surface 1072. Side bearing section 1074 includes a first free section 1076 (e.g., a secondary tab) and a second free section 1078 that are not adhered to the receiving surface 1072. The pictured first free section 1076 is formed of a section folded in on itself and joined by an adhesive layer. The lateral support section 1074 also includes a first adhered section 1077 that is adhered to the first adhered section of the central support section 1075B (e.g., through an adhesive layer) and a second adhered section 1079 that is adhered to the upper surface of the object. 1073 (eg through an adhesive layer). As shown, side support section 1074 wraps around the outer edge of object 1073.
[00228] Figure 47 depicts a side view of the exemplary removable cover 1071 and object 1073 of Figure 46 in a folding phase. In particular, the first free section 1076 (e.g., a secondary tab) has been folded into the upper surface of the second bonded section 1079. Additionally, the left and right center tab 1075A has been folded into the lower or outer surface of the first bonded section 1075B.
[00229] Figure 48 depicts a side view of the exemplary removable cover 1071 and object 1073 of Figure 46 in an additional folding stage. In particular, the right side of the removable cover 1071 and object 1073 has been folded up around a geometrical folding axis located approximately at the right edge of block 1070 so that the first free section 1076 is over the central portion of the object. 1073.
[00230] Figure 49 depicts a side view of the exemplary removable cover 1071 and object 1073 of Figure 46 in an additional folding stage and within an exemplary packaging system 2000. In particular, the left side of the removable cover 1071 and the object 1073 has been bent up around a geometrical bending axis located approximately on the left edge of block 1070 so that the first free section 1076 is over (i) the right side of the removable cover 1071 and (ii) the central portion of object 1073. In other exemplary embodiments, the left side of removable cover 1071 and object 1073 can be folded before the right side of removable cover 1071 and object 1073. The folded removable cover 1071 and object 1073 are within the system of 2000 packaging.
[00231] The 2000 packaging system includes two pieces, a 2000 A left sleeve and a 2000 B right sleeve, which may or may not be joined by a 2001 adhesive layer. The 2000 A and 2000 B sleeves each include one part upper 2003 A and 2003 B and a lower 2002 A and 2002 B, respectively.
[00232] Exemplary removable cover 1071 and packaging system 2000 work together to facilitate placement of object 1073 and its receiving surface 1072. In this regard, each central flap of central support section 1075A (i.e., in portions The left and right side of the removable cover 1071) is typically adhered to each respective lower 2002 A or 2002 B part of the packaging system 2000. When a user moves the left and right gloves 2000 A and 2000 B away from each other, the section support of the removable cover 1075 is also at least partially removed. Additionally, the natural elastic tension unfolds the left and right sides of the removable cover 1071 and object 1073 as the 2003 A and 2003 B tops move apart. After object 1073 and receiving surface 1072 are placed, first free section 1076 on each side can be engaged to remove side support section 1074 and removable cover 1071.
[00233] In this regard, exemplary embodiments of the present invention encompass a removable cover that provides a change in peel strength along a force vector through which a variety of mechanisms can be attached to a receiving surface along a flexible object and surrounded by a connected package. Flexible object and removable cover can be folded to smaller dimensions and packaging materials. Removal of the integrated packaging simultaneously unfolds the flexible object and removes the cover through peeling as noted above. Any mechanism that increases resistance to detachment is available for integration in this modality.
[00234] Figure 50 depicts a side view of two exemplary removable covers 1101 A and 1101 B and an object 1103 that has a receiving surface 1102 (eg, an adhesive layer). As shown, exemplary removable covers in accordance with the present invention can be adhered to the top of an object 1103 (e.g., through an adhesive layer 1000) as does exemplary removable cover 1101 A to the left or bottom of a object 1103 (e.g. when receiving surface 1102 is an adhesive layer, or through an adhesive layer) as does exemplary removable cover 1101B on the right. As shown, exemplary removable covers 1101A and 1101B each include a first free section 1104A and 1104B, respectively, that are not adhered to object 1103 or receiving surface 1102. Exemplary removable covers 1101A and 1101B each also include one, an adhered section 1105A and 1105B, respectively, which are adhered to object 1103 and receiving surface 1102, respectively. By changing the adhesion location (ie top or bottom of the object) in relation to the relative elastic quality of the peelable or the relative elasticity of the object, the release mechanism of the peelable can be controlled.
[00235] For example, Figures 51 and 52 depict an exemplary removable cover 1081 that is less elastic (i.e. less flexible, less expandable and/or more rigid) than object 1083 and its adhesive layer 1082. The exemplary removable cover 1081 includes a first free section 1084 that is not adhered to object 1083 and a first adhered section 1085 that is adhered to the lower surface (i.e., receiving surface 1102) of object 1083.
[00236] In Figure 52, a tension is applied to the first free section 1084. Due to the fact that the object 1083 and its adhesive layer 1082 are more elastic (ie more flexible, more expandable and/or less rigid) than the removable cover 1081, they deform. The combination of this deformation and the difference in elasticity causes the free end of the first bonded section 1085 (that is, the end opposite the connection for the first free section 1084 or the left end as shown) to release from the adhesive layer 1082 before the rest of first adhered section 1085. In other words, the shear tensile strength of adhesive layer 1082 is overcome first at the portion of release liner 1081 which is furthest from the location to which the peel force is applied (i.e., at the free end of the first free section 1084). Typically, adhesive layer 1082 remains on object 1083 after removal in this exemplary embodiment.
[00237] As another example, Figures 53 and 54 depict an exemplary removable cover that is more elastic (i.e., more flexible, more expandable, and/or less rigid) than object 1093 and adhesive layer 1090. includes a first free section 1094 that is not adhered to object 1093 and a first adhered section 1095 that is adhered to the upper surface of object 1083 through adhesive layer 1090.
[00238] In Figure 54, a tension is applied to the first free section 1094. Due to the fact that the removable cover 1091 is more elastic (ie, more flexible, more expandable and/or less rigid) than the object 1093, the 1091 removable cover deforms (eg stretches). The combination of this deformation and the difference in elasticity causes the end of the first bonded section 1095, which is connected to the first free section 1094 (ie, the left end as pictured or the end opposite the free end), to release the object 1093 before the rest of the first adhered section 1095. In other words, the shear tensile strength of the adhesive layer 1090 is overcome first in the portion of the release liner 1091 that is closest to the location to which the peel force is applied ( that is, at the free end of the first free section 1094). Typically, adhesive layer 1090 remains on release liner 1091 after removal and deforms similarly to release liner 1091 in this exemplary embodiment.
[00239] In this regard, exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a force vector by means of different expandability characteristics between the removable cover and the attached receiving surface . Any mechanism that increases resistance to peeling is available for integration in this modality and can incorporate the expansion feature into the cover or object that has a receiving surface. If the side section of the removable cover (under shear force) is more elastic than the receiving surface, then the force vector will cause a progressive shear failure to start at the side end of the receiving surface and advance centrally. If the removable cover section (under shear force) is less elastic than the receiving surface, then the force vector will cause a progressive shear failure to start at the center end of the receiving surface and advance laterally.
[00240] A resistance to removal of the removable cover from an object can be changed by varying the rigidity or flexibility of the removable cover at different locations along an adhered section. For example, Figure 55 depicts a side view of an exemplary packaging system 2000, the removable cover 1111 and the object 1113 having a receiving surface 1112 (e.g., an adhesive layer). Each side (i.e., the left and right sides) of the exemplary removable cover 1111 includes a primary tab 1114 (e.g., a central end or a free section), a lateral reinforcement section 1117, and an adhesive layer 1116 that are not adhered to the receiving surface 1112 of the object 1113. The removable cover 1111 also includes a central section 1115 (e.g., an adhered section) which is adhered to the receiving surface 1112. The lateral reinforcement section 1117 is adhered to the lower surface of the central section 1115 through adhesive layer 1116.
[00241] The 2000 packaging system includes two pieces, a left sleeve 2000 A and a right sleeve 2000 B, which may or may not be joined by an adhesive layer. 2001 Sleeves 2000 A and 2000 B each include a top 2003 A and 2003 B and a lower 2002 A and 2002 B, respectively.
[00242] Exemplary removable cover 1111 and packaging system 2000 work together to facilitate placement of object 1113 and its receiving surface 1112. In this sense, each primary flap 1114 (i.e., on the left and right portions of the removable cover 1111) is typically adhered to each respective lower 2002 A or 2002 B of packaging system 2000 (for example, through adhesive layer 1118 as shown).
[00243] Figures 56 to 58 depict side views of the exemplary removable cover 1111, the object 1113 and the packaging system 2000 of Figure 55 at different stages of removal. As shown in Figure 56, when a user pulls the left and right sleeves 2000 A and 2000 B apart, the removable cover 1111 is removed as well. Initially, there is a 180 degree peel force resistance as the center section 1115 is removed from the receiving surface 1112. After the first portion of the center section 1115 has been removed as shown in Figure 57, the peel force resistance increases due to the side reinforcement section 1117 and the adhesive layer 1116. The thicker section (ie, the side reinforcement section 1117 and the adhesive layer 1116) can increase peel strength by: (i) requirement of an angle of detachment that is closer to a 90 degree detachment than a 180 degree detachment in the thinnest section and/or (ii) increasing the area of the lateral portion of the central section 1115 that needs to be detached from the receiving surface 1112 thereto time.
[00244] Varied peel strength resistance such as this can be achieved using a variety of techniques. For example, instead of stacking sections of the removable cover (for example, as shown in the left half of Figure 61), the thickness of a portion of the removable cover can be increased or decreased. The variation in thickness can be gradual, stepwise, or abrupt to provide a range of smooth to sharp changes in strength. Furthermore, the location along the receiving surface at which the resistance change occurs may vary. For example, the change in strength can occur due to a change in thickness in the middle of the portion of the removable cover that is adhered to the receiving surface (for example, as shown in the right half of Figure 61).
[00245] In this regard, the exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a force vector, by means of a change in the flexibility of the removable cover. In phase 1 (eg Figure 56), the center section of the removable cover is peeled off at a peel angle of 90 to 180 degrees as the packaging is separated, if the side edge of the removable cover is stiffer, the peel angle it is momentarily inferior and more resistance to detachment is present.
[00246] As previously noted with respect to Figure 34, varying peel strength resistance can be achieved by varying the texture of the peelable cover. Exemplary release liners may also have achieved varying peel strength resistance that includes a varying release liner (eg, to provide varying strength to adhesion). For example, Figure 59 depicts a perspective view of an exemplary object 1123, an adhesive layer 1122, and two exemplary removable covers 1121 A and 1121 B. Exemplary removable covers 1121 A and 1121 B each include a primary tab 1124 (for example, a center terminal or a free section) and a center section 1125. Shading identifies areas of more or less coating for release: Darker areas indicate more coating for release and lighter areas indicate less coating for release .
[00247] Consequently, as the removable cover 1121 A is removed by pulling the primary tab 1124, initially there is a low resistance to peel force, followed by a medium resistance to peel force and finally a high resistance to peel force . In other words, progressively greater force is required to remove the removable cover 1121 A during the removal process.
[00248] As the removable cover 1121 B is removed by pulling the primary tab 1124, initially there is a high peel strength, followed by a low peel strength, then a medium peel strength, then , a high resistance to peeling force and finally a low resistance to peeling force.
[00249] As previously noted, Figure 61 depicts a side view of two exemplary removable covers and an object illustrating configurations capable of achieving varied strength through supporting stacking layers, and of changing the location of the increased strength.
[00250] The graph on the left side of Figure 60 graphically depicts the force required to remove the peelable covers on the left side of Figures 59 and 61 as a function of the distance from the midpoint of the adhesive layer. The graph on the right side of Figure 60 graphically depicts the force required to remove the peelable cover on the right side of Figure 61 as a function of distance from the midpoint of the adhesive layer. The units on the x-axis of both graphs are arbitrary.
[00251] Yet another technique for varying a peel strength of the removable cover employs loops such as those described with reference to Figures 11 to 22. In particular, increasing the length of a given loop will increase the peel strength by increasing of the percentage of strength, which is a resistance to the shear force. On the other hand, decreasing the length of a given loop will decrease the peel strength by decreasing the percentage of strength, which is a resistance to shearing force.
[00252] Yet another technique for varying a peel strength of the removable cover employs folds such as those described with respect to, for example, Figures 1 to 10. In particular, increasing the length of a given fold will increase the strength to removal by increasing the percentage of strength that is a resistance to shearing force. Conversely, decreasing the length of a given bend will decrease the peel strength by decreasing the percentage of strength that is a resistance to shear force.
[00253] The interaction between a removable cover and a packaging system can also achieve varied peel strength. For example, Figure 62 depicts an aerial view of an exemplary packaging system. The packaging system has a top surface and a bottom surface that are adhered together at the outer edges as indicated by the textured area. White space and dotted lines indicate free interior space between the top and bottom surfaces. As shown, the free space tapers from a width W near the left and right edges to a width t near the midline. The left and right portions (ie, as separated by the midline) may or may not adhere to each other at the midline.
[00254] Figure 63 depicts an aerial view of an exemplary removable cover and/or an object. The left and right halves of the removable cover and/or object are different to illustrate the varied strength that can be achieved.
[00255] Figure 64 graphically depicts the force required to remove the packaging system of Figure 62 from the removable cover of Figure 63 to the left and right sides of the removable cover of Figure 63 as a function of the distance from the midpoint of the packaging system . As shown, the shape of the removable cover and/or object, as it interacts with the tapered width of the free space within the packaging system, varies the resistance to peeling.
[00256] In this regard, the exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance for cover removal along a force vector by varying the texture of the removable cover or receiving object in changes gradual or staggered. Coarser textured areas are less tacky due to the reduced adhesive surface area and, in contrast, softer areas are more tacky.
[00257] Figure 65 depicts an aerial view of an exemplary removable cover and/or an object within an exemplary packaging system. As in Figure 62, the packaging system has an upper surface and a lower surface that are adhered together at the outer edges as indicated by the textured area. Removable cover and/or object is shown in the free interior space between the top and bottom surfaces. In this depicted embodiment, there is less variation in strength, and the variation is less abrupt than in Figures 62 to 64 due to the fact that the packaging system and the removable cover and/or the object have (i) a reduced width variation and (ii) corresponding contours (ie, the adhered edges of the packaging system and the width of the removable cover and/or object).
[00258] Figure 66 depicts an aerial view of an exemplary removable cover 3001 that includes a body section 3002, a secondary pull tab 3003 and an opening 3004 in body section 3002. Figure 67 depicts a perspective view of the cover Exemplary removable 3001 of Figure 66 with an initial bend geometry axis.
[00259] Figure 68 depicts a perspective view of exemplary removable cover 3001 after secondary pull tab 3003 has been folded over the initial fold axis shown in Figure 67. The end of secondary pull tab 3003 is passed through the opening 3004 in body section 3002. Figure 68 also shows the secondary bend axis.
[00260] Figure 69 depicts a perspective view of the exemplary removable cover 3001 after the left portion of the body section 3002, the opening 3004 and the secondary pull tab 3003 have been folded over the secondary fold axis. As pictured, secondary pull tab 3003 extends outwardly to the left of removable cover 3001.
[00261] Figure 70A depicts a perspective view of the exemplary removable cover 3001, as manufactured in the stages depicted in Figures 67 to 69, and an object 3008. The object 3008 can be adhered to the removable cover 3001 (for example, through an adhesive layer). The right portion of body section 3002 has been folded down to form a primary pull tab 3005.
[00262] Figure 70B depicts a perspective view of the exemplary removable cover 3001 and the object 3008 of Figure 70A after the secondary pull tab 3003 has been folded around the outer edge of the object 3008. The secondary pull tab 3003 can be adhered to object 3008 (e.g., through an adhesive layer) and may include another tab (not shown) that is not adhered to object 3008.
[00263] Figure 71 depicts an aerial view of an exemplary removable cover 3011 that includes a body section 3012, a secondary pull tab 3013 and a fin section 3014 formed in the body section 3002 by three linear apertures. Figure 72 depicts a perspective view of the exemplary removable cover 3011 of Figure 71 with two initial folding movements.
[00264] Figure 73 depicts a perspective view of the removable cover 3011 after the secondary pull tab 3013 has been folded under the fin section 3014. As shown in Figure 74, the secondary pull tab 3013 is further pulled and the portion left of body section 3012 is tucked under fin section 3014.
[00265] Figure 75 depicts a perspective view of the removable cover 3011 after the secondary pull tab 3013 has been folded back on itself around the left portion of the body section 3012. As pictured, the secondary pull tab 3003 extends out to the left of the removable cover 3001. An object can be placed on top of the body section 3012 and the fin section 3014, the secondary pull tab can be folded around the outer edge of the object and/or the portion. The right hand side of body section 3012 can be folded down to form a primary pull tab (not shown).
[00266] Figure 76 depicts a perspective view of the center section 3021 of an exemplary removable cover. The center section 3021 includes a link section 3023, a body section 3022, and an opening 3024 in the body section 3022. As shown, the link section 3023 is bent about an initial bend axis.
[00267] Figure 77 depicts a perspective view of the center section 3021 after the connecting section 3023 has been bent about the initial bend axis shown in Figure 76. Figure 77 also shows the secondary bend axis.
[00268] Figure 78 depicts a perspective view of the central section 3021 after the link section 3023 has been bent about the secondary bend axis shown in Figure 77. As shown, a portion of the link section 3023 is positioned in the opening 3024.
[00269] Figure 79 depicts a perspective view of the center section 3021 and an object 3028 with a receiving surface 3029 (eg an adhesive layer).
[00270] Figure 80 depicts a perspective view of the central section 3021, the object 3028 and an extension section 3027. As shown, the object 3028 and the receiving surface 3029 are positioned in the connecting section of the central section 3023 and in the body section 3022. The object 3028 can be adhered to the center section 302 (for example, through an adhesive layer). The right portion of body section 3022 has been folded down to form a primary pull tab 3025.
[00271] Extension section 3027 includes an extension body 3027 B and extension link 3027 A. Extension link 3027 A is typically adhered to the portion of link section 3023 positioned in opening 3024. Extension section 3027 may be folded around the edge of the object 3028 and can also be adhered to the upper surface of the object 3028 (eg, through an adhesive layer).
[00272] In Figures 76 to 80, the center section 3021 and the extension section 3027 can function together as an exemplary removable cover. As shown, the example removable cover can be applied to an object. That said, two removable covers according to Figures 76 to 80 can be used together, one in the orientation shown in Figures 76 to 80 and one rotated 180 degrees in the same plane around the right edge of the body section 3022. a single, larger removable cover that has the same left and right sides can be used on a larger object.
[00273] For example, Figure 81 depicts a side view of such a removable cover and an object 3028 that has a receiving surface 3029 (eg an adhesive layer). In other words, the left and right sides of the removable cover each include a center section 3021 and an extension section 3027. The center section 3021 includes a connecting section (not shown), a body section 3022, an opening (not shown) on the body section 3022 and a primary pull tab 3025. The extension section 3027 includes an extension body 3027 B and an extension link 3027 A. As shown in Figure 81, the extension section 3027 is bent around the edge of object 3028.
[00274] Figure 82 depicts a side view of the exemplary removable cover and object 3028 of Figure 81 in a removal phase. In particular, the center section primary pull tab 3025 was pulled with a force to overcome a 180 degree peel force resistance and the center section body section 3022 was removed from the receiving surface 3029.
[00275] Figure 83 depicts a side view of the exemplary removable cover and object 3028 of Figure 81 in an additional removal stage. In particular, the primary pull tab of the central section 3025 has been pulled to its full extent, leaving the portion of the connecting section 3023, which has been bent over the secondary bend axis (see Figures 77 and 78), adhered to the surface of reception 3029. In this position, there is a resistance to shear disengagement force to a pulling force at the ends of the center section 3021.
[00276] Figure 84 depicts a side view of the exemplary removable cover and the object of Figure 81 in an additional phase of removal. In particular, the extension section 3027 has been engaged by pulling on the portion of the extension body 3027 B that has been bent over the object 3028. Due to the folded configuration around the connection of the center section 3021 and the extension section 3027, the force required to remove the removable cover must overcome a 180 degree peel force resistance.
[00277] In this regard, the exemplary embodiments of the present invention encompass a removable cover that provides a change in strength to cover removal along a force vector through a crisscross construction that varies the resistance to peeling on different surfaces of the object to which the coverage binds.
[00278] For example, Figure 85 depicts a side view of an exemplary 2010 packaging system, the removable cover 1131 and the object 1133 which has a receiving surface 1132 (eg an adhesive layer). Each side (i.e., left and right side) of exemplary removable cover 1131 includes a primary flap 1134 (e.g., a center terminal or a free section) and an extension section 1136 that are adhered to receiving surface 1132 of object 1133 Removable cover 1131 also includes a central section 1135 (e.g., a bonded section) that is bonded to the receiving surface 1132.
[00279] As shown, extension section 1136 extends beyond the outer edge of object 1133. Extension section 1136 interacts with the 2010 packaging system to provide additional strength for complete removal and can have a variety of shapes (such as viewed from the area view).
[00280] The 2010 packaging system includes two pieces, a 2010 A left sleeve and a 2010 B right sleeve, which may or may not be joined by a 2011 adhesive layer. The 2010 A and 2010B sleeves each include a top 2013A and 2013B and a lower part 2012A and 2012B, respectively.
[00281] Exemplary removable cover 1131 and packaging system 2010 work together to facilitate placement of object 1133 and its receiving surface 1132. In this sense, each primary flap 1134 (i.e., on the left and right portions of the removable cover 1131) is typically adhered to each respective 2012 A or 2012 B bottom part of the 2010 packaging system (for example, through adhesive layer 1138 as shown).
[00282] Figures 86 to 88 depict the side views of the exemplary removable cover, object 1133 and the 2010 packaging system of Figure 85, in different stages of removal. As shown in Figure 86, when a user pulls the left and right 2010 A and 2010 B gloves apart, the removable cover 1131 is removed as well. Initially, there is a 180 degree peel force resistance as center section 1135 is removed from receiving surface 1132. As discussed, extension section 1136 interacts with packaging system 2010 to provide additional resistance to complete removal. Figure 87 depicts the moment at which the extension section 1136 begins to interact with the 2010 packaging system in this exemplary modality. In particular, the extension section 1136 is taken up in the 2010 packaging system, thereby increasing the peel strength, before the center section 1135 is removed from the receiving surface 1132. , a user can more easily apply the object to a surface before completely removing the 1131 removable cover and 2010 packaging system.
[00283] Figures 89 to 92 depict aerial views of the example packaging system 2010, the removable cover 1131 and object 1133 in the different phases of removal depicted in Figures 85 to 88, respectively. In this sense, the 2010 packaging system is shown, which includes the left glove 2010A and the right glove 2010B with their respective uppers 2013A and 2013B. The outermost dotted lines indicate the clearance 2014A and 2014B within the 2010 packaging system portion between a given upper and lower part of the sleeve (see also Figures 85 to 88). In addition to the dotted lines, the top and bottom of the gloves are adhered to each other. The interior dotted lines indicate the location of the extension section 1136 and object 1133. The other components of the removable cover 1131 (for example, center section 1135 and primary flap 1134) are below object 1133 and are therefore not shown in Figures 89 or 90.
[00284] As shown, the 1136 extension sections have a tapered shape and the 2014A and 2014B headspace tapers in width near the center edge of each 2010A and 2010B sleeve. As shown in Figure 91, when a user pulls the 2010 A and 2010B left and right gloves apart, the extension section 1136 encounters the tapered portion of the 2014A and 2014B clearance inside the 2010 packaging system. In Figure 91, a portion of center section 1135 is shown extending outward of extension section 1136. As discussed, this interaction of extension section 1136 and packaging system 2010 increases peel strength and facilitates user placement and object application 1133. The peel strength between the extension section 1136 at this point is equivalent to a shear peel strength resistance, while the peel strength between the center section 1135 and the receiving surface 1132 is a resistance to the shear peel force of 180 degrees weaker.
[00285] As shown in Figure 92, the extension section 1136 may force open the tapered portion of the clearance 2014A and 2014B within the packaging system 2010 or the extension section 1136 may deform to pass through the central edge of the system of packaging 2010.
[00286] Extension sections that interact with a packaging system can have a variety of shapes to provide variable peel strengths and can be adhered to the top of an object. For example, Figures 93 and 94 depict perspective views of example extension sections 4001. As shown, extension sections 4001 include body section 4002, a resistance feature 4003 and a pull tab 4004. of extension section 4003 in Figure 93 is shaped to accommodate the pickup (i.e., within the circle) of the package with which it interacts. Extension section strength feature 4003 in Figure 94 is located in the middle of body section 4002 to provide earlier strength in the removal process compared to extension section strength feature 4003 in Figure 93. Alternatively, the length of the body section 4002 can be increased or decreased or the placement of the extension section 4001 on the object or the removable cover can be varied to achieve the increased strength at a given stage of the removal process.
[00287] Figure 95 depicts a perspective view of two exemplary extension sections 4001 A and 4001 B adhered to the top surface of an object 1143 that has a receiving surface 1142 adhered to an exemplary removable cover 1141. As shown, the sections extension lengths 4001 A and 4001 B each include a 4002A and 4002B body section, a 4003A and 4003B resistance feature, and a 4004A and 4004B pull tab. Pull tabs 4004A and 4004B can be engaged to remove extension sections 4001A and 4001B from object 1143. Alternatively, pull tabs 4004A and 4004B can be adhered to the packaging in such a way that extension sections 4001A and 4001B removed as the packaging is pulled by the user.
[00288] Figures 96 through 97 depict an exemplary two-piece extension section 4011 that includes a 4012 body section and a 4013 resistor feature. As shown, the 4013 resistor feature can be adhered to the 4012 body section that it creates a two-layer zone shown in Figure 97.
[00289] Figures 98 through 99 depict another exemplary two-piece extension section 4011 that includes a body section 4012 and a different resistor feature 4013. As shown, the resistor feature 4013 can be adhered to the body section 4012 which creates a two-layered zone shown in Figure 99. As compared to the two-layered zone in Figure 97, the two-layered zone in Figure 99 is smaller, which can provide improved fabrication or functionality advantages.
[00290] Figures 100 to 101 depict another exemplary two-piece extension section 4021 that includes a body section 4022 and a resistor feature 4023 that additionally includes an opening 4025. The opening 4025 provides a zone of two smaller layers, which can provide the advantages of improved manufacturing or functionality.
[00291] Figure 102 depicts a side view of an exemplary removable cover 1151, exemplary extension sections 4031, and an object 1153 that has a receiving surface 1152 (eg, an adhesive layer). Each side (i.e., the left and right sides) of the exemplary removable cover 1151 has the same components. Removable cover 1151 includes a primary flap 1154 that is not adhered to the receiving surface 1152 and a first adhered section 1155 that is adhered to the receiving surface (e.g., via an adhesive layer). As shown, primary tab 1154 is adhered to gusset section 1159 through adhesive layer 1158. gusset section 1159 may not be included in some exemplary embodiments.
[00292] Exemplary extension sections 4031 are adhered to the side portion of each side of the removable cover 1151 (i.e., the first adhered section of the removable cover 1155) through an adhesive layer 1156. In this connection, the overlapping portions and The adhered first mating section of the removable cover 1155 and the extension section 4031 form a two-layer backing, which affects the resistance to removal of the removable cover.
[00293] Figure 103 depicts exemplary removable cover 1151, exemplary extension sections 4031, and object 1153 of Figure 102 within a 2020 packaging system. The 2020 packaging system includes two pieces, a left sleeve 2020A and a right sleeve 2020B, which may or may not be joined by an adhesive layer 2021. Gloves 2020A and 2020B each include an upper 2023A and 2023B and a lower 2022A and 2022B, respectively.
[00294] Exemplary removable cover 1151, exemplary extension sections 4031, and packaging system 2020 work together to facilitate placement of object 1153 and its receiving surface 1152. In this connection, each bracing section 1159 (i.e., in the left and right portions of the removable cover 1151) is typically adhered to each respective lower part 2022A or 2022B of the packaging system 2020. In alternative embodiments, each primary flap 1154 is adhered to each respective lower part 2022A or 2022B of the packaging system 2020. .
[00295] Figures 104 to 106 depict side views of the exemplary removable cover 1151, object 1153, exemplary extension sections 4031, and packaging system 2020 of Figure 102 at different stages of removal, while Figure 107 graphically depicts the application force or resistance required to remove exemplary removable cover 1151 from object 1153 as a function of time. In Figure 107, "Phase 0" corresponds to Figures 102 and 103; "Phase 1" corresponds to Figure 104; and "Phase 2" corresponds to Figure 105.
[00296] As shown in Figure 104, when a user moves the 2020A and 2020B left and right gloves away from each other, the removable cover 1151 is also removed. Phase 0 is followed by the separation of the left and right gloves 2020A and 2020B which requires the application of a medium opening force. Phase 1 requires a force to overcome a 180 degree peel force resistance.
[00297] In Phase 2, the force transitions required from the force required to overcome a 180-degree detachment force resistance to a force that has the ability to overcome (i) a resistance to constriction and (ii) a resistance to increased 180 degree peel force. The crimp strength is a result of the interaction between the 4031 extension sections and the 2020 packaging system described in relation to Figures 62 to 65 and 85 to 101. In this regard, the crimp strength depends on the shape of the extension sections 4031 and the interior clearance and construction of the 2020A left and right sleeves. Thus, the 4031 extension sections and the 2020A left and right sleeves can be designed to achieve a particular constricting force.
[00298] As noted, Phase 2 requires a force that has the ability to overcome (i) the constriction resistance and (ii) an increased 180 degree peel force resistance. The increased 180 degree peel force resistance is a result of the two-layer support formed by the overlapping and bonded portions of the extension section 4031 and the first bonded section 1155 of the removable cover. See, for example, Figure 105. After Phase 2, the constriction resistance and the increased 180 degree peel force resistance are overcome.
[00299] Figures 108 through 112 depict aerial views of exemplary extension sections 4041 and exemplary removable covers 1161. The depicted extension sections 4041 include a body section 4042 and a resistance feature 4043. As shown in Figure 108, when a extension section 4041 is applied to a removable cover 1161, at least a portion of the body section 4042 overlaps the removable cover 1161 to form an overlap zone 4046. As the overlap zone is thicker, it is more rigid or less deformable than the removable cover 1161 or strength feature 4043. By varying the shape of the 4046 overlap zone, therefore, the peel strength can also vary as the removable cover 1161 and/or 4041 extension sections interact with a package for create a constricting resistance.
[00300] For example, the overlap zone 4046 in Figure 109 is wider than the overlap zone in Figure 110. Thus, for a given width at a packaging constriction point, the extension section 4041 and removable cover 1161 of Figure 109 will provide more pinch strength than the extension section 4041 and removable cover 1161 of Figure 109.
[00301] In addition, the rate at which the constriction resistance increases can also be varied using the overlap zone 4046 shape. For example, the overlap zone 4046 of Figure 109 will cause an abrupt increase in the constriction resistance as the overlap zone 4046 reaches the constriction point. In contrast, the overlap zone 4046 of Figure 111 will provide a gradual increase in constriction strength as more of the overlap zone 4046 passes through the constriction point (i.e., top to bottom). Ultimately, the overlap zone 4046 of Figure 110 will provide a slight gradual increase in crimp strength (i.e., less increase in crimp strength per distance pulled when compared to Figure 111).
[00302] As shown in Figure 112, the variation in constriction resistance created by the shape of the extension section 4041 and its resistance feature 4043 can be estimated by comparing the width W1 of the removable cover 1161 and the maximum width W2 of the resistance feature 4043 of the extension section. Typically, a larger difference between the strength feature width W2 and the removable cover width W1 will result in a higher pinch strength.
[00303] Figure 113 depicts a side view of an exemplary packaging system 2030, removable cover 1171, and object 1173 that has a receiving surface 1172 (e.g., an adhesive layer). Each side (i.e., left and right sides) of exemplary removable cover 1171 includes a primary flap 1174 (e.g., a center end or free section) and an extension section 1176 that are not adhered to the object receiving surface 1172. 1173. Removable cover 1171 also includes a center section 1175 (eg, a bonded section) that is bonded to the receiving surface 1172.
[00304] As shown, extension section 1176 extends beyond the outer edge of object 1173. Extension section 1176 interacts with packaging system 2030 to provide additional resistance to complete removal and can have a variety of shapes (as seen from above).
[00305] The 2030 packaging system includes two parts, a left sleeve 2030A and a right sleeve 2030B, which may or may not be joined by an adhesive layer 2031. The gloves 2030A and 2030B each include an upper 2033A and 2033B and a bottom 2032A and 2032B, respectively. Sleeves 2030A and 2030B each also include a clearance 2034A and 2034B between their respective upper and lower sides.
[00306] Exemplary removable cover 1171 and packaging system 2030 work together to facilitate placement of the object 1173 and its receiving surface 1172. In this regard, each primary flap 1174 (i.e., on the left and right portions of the removable cover 1171) is typically adhered to each respective underside 2032A or 2032B of packaging system 2030 (e.g., through adhesive layer 1178 as shown).
[00307] Figure 114 depicts a top view of the example packaging system 2030, removable cover 1171 and object 1173. As shown, gloves 2030A and 2030B each also include a pickup section 2035A and 2035B and a point of constriction 2036A and 2036B. Each constriction point is created by adhering to the top and bottom of a given glove so that the clearance is narrower near the center or midline of the 2030 packaging system.
[00308] Figure 115 graphically depicts the application force or resistance required to remove the exemplary removable cover 1171 from object 1173 as a function of time. In Figure 115, "Phase 0" corresponds to Figures 113 and 114.
[00309] When a user moves (eg through pickup sections 2035A and 2035B) the left and right sleeves 2030A and 2030B from each other, the removable cover 1 171 is also removed. Phase 0 is followed by the separation of the left and right sleeves 2030A and 2030B, which requires the application of a separation force at the midline. Phase 1 requires a force to overcome a 180 degree peel force resistance as center section 1175 is peeled away from receiving surface 1172.
[00310] In Phase 2, the force required increases from the force required to overcome the 180 degree peel strength resistance to a force that has the ability to overcome a constriction resistance. The crimp strength is a result of the interaction between the 1176 extension sections and the 2030 packaging system described in relation to Figures 62 to 65 and 85 to 112. In this regard, the crimp strength depends on the shape of the extension sections 1176, free spaces 2034A and 2034B, and constriction points 2036A and 2036B. For example, as shown in Figure 114, the maximum width of extension sections 1176 is greater than the width of constriction points 2036A and 2036B. Thus, when sleeves 2030A and 2030B have been pulled far enough apart so that extension sections 1176 meet crimp points 2036A and 2036B, a crimp strength will prevent further separation of the sleeves. During Phase 2, most, if not all, of the object 1173 and its receiving surface 1172 will be outside the 2030 packaging system, and the user can hold the 2030 packaging system and place the 1173 object and the surface of reception of it 1172 in a desired location (for example, on another surface).
[00311] During Phase 3, the user pulls the 2030A and 2030B gloves away with sufficient force to overcome the constriction resistance. Pinch strength can be overcome through distortion of extension sections 1176 or failure of adhesive between the top and bottom of sleeves at pinch points 2036A and 2036B.
[00312] In this regard, the exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a force vector by means of a constriction mechanism that varies the amount of resistance exhibited by the packaging and, therefore, the resistance to detachment of the support. In embodiments in which the removal of the carton also peels off the removable cover, the peel strength can be adjusted by incorporating a snap-in feature that restricts the ability of the removable cover to slide through a passage in the package.
[00313] Figure 116 depicts a perspective view of an exemplary packaging system 5000 that includes right and left gloves that have the same components. In particular, each glove includes an upper 5001, a manipulation element 5002, an upper flap 5003, a lower flap 5004, and a lower flap 5005. The strap element 5002 is a strap that has ends adhered to the upper 5001. In use, a user can place two fingers of the same hand on each grip element 5002 and expose an object inside the gloves by spacing the two fingers apart.
[00314] Figure 117 depicts a perspective view of another exemplary packaging system 5010 that includes left and right gloves that have the same components. In particular, each glove includes an upper portion 5011, a strap element 5012, an upper flap 5013, a lower portion 5014 and a lower flap 5015. The strap element 5012 is a D-shaped ring that has a flat portion adhered to it. to the outer edge of each glove. Again, in use, a user can place two fingers of the same hand on each grip element 5012 and expose an object inside the gloves by spacing the two fingers apart.
[00315] Figure 118 depicts a perspective view of yet another exemplary packaging system 5020 that includes left and right gloves that have the same components. In particular, each glove includes an upper portion 5021, a strap element 5022, an upper flap 5023, a lower portion 5024, and a lower flap 5025. The strap element 5022 is created through an arc-shaped perforation in the edge. external of each glove. As shown, the arc-shaped piercing does not overlap the 5026 object inside the sleeves. Arc-shaped perforations may or may not extend to the outer edges of the sleeves. In use, a user can break the perforation on each glove, place two fingers of the same hand on each grip element 5022, and expose an object inside the gloves by spacing the two fingers apart.
[00316] Figure 119 depicts a perspective view of yet another exemplary packaging system 5030 that includes left and right gloves that have the same components. In particular, each glove includes an upper portion 5031, a grip element 5032, an upper flap 5033, a lower portion 5034, and a lower flap 5035. The grip element 5032 is a circular opening formed by an arch of packaging material. extending from the outer edge of each glove and a cut from the outer edge of each glove. Again, in use, a user can place two fingers of the same hand in each circular opening and expose an object inside the gloves by spacing the two fingers apart.
[00317] In this regard, exemplary embodiments of the present invention encompass a removable cover that provides a change in resistance to cover removal along a force vector by means of a change in the direction of the removable cover that results from manual extension of the packaging via attached or integral straps (eg strap elements). The user separates the package through the handles or flaps, and the package provides a first peel force vector at a first peel strength and peel angle. The user can then complete the peel off by accessing the secondary flaps (eg top flaps and/or bottom flaps) that are peeled off at a peel angle between 90 and 180 degrees.
[00318] Figures 120 to 123 depict aerial views of an exemplary packaging system 6000 and object 6002. The packaging system 6000 includes a left sleeve 6000A and a right sleeve 6000B that each include a visible design element 6001A and 6001B (eg an image of a hand). As shown in Figure 123, object 6002 carries a centrally positioned 6003 visible design element (for example, a one-face image), a 6004A left-hand visible design element (for example, a hand image) and a 6004B right-side visible design element (eg an image of a hand). In the exemplary embodiment depicted, visible design elements 6001A and 6001B are the same as left side visible design element 6004A and right side visible design element 6004B, although the size of the elements may be different. In addition, the pictured exemplary design elements are related in such a way as to convey a story as sleeves 6000A and 6000B of packaging system 6000 are removed from object 6002.
[00319] As shown in Figure 121, during a first phase of removal, the centrally positioned design element 6003 becomes visible as sleeves 6000A and 6000B are separated. As pictured, the transmitted story shows a face, originally hidden behind two hands, being revealed as the two hands move outward to the left and right.
[00320] During a second removal phase depicted in Figure 122, the left-hand visible design element 6004A and the right-hand visible design element 6004B on object 6002 become partially visible as sleeves 6000A and 6000B are further separated more additionally. As pictured, the story conveyed shows that the face is still visible and both hands appear to be ceasing further movement on either side of the face.
[00321] During the final removal phase depicted in Figure 123, the left-hand visible design element 6004A and the right-hand visible design element 6004B on object 6002 are completely visible and sleeves 6000A and 6000B have been completely removed from the object 6002. As pictured, the story broadcast shows that the face is still visible and both hands have stopped moving and are positioned on either side of the face.
[00322] Figures 124 to 126 depict aerial views of another exemplary packaging system 6010 and object 6012. Packaging system 6010 includes a left sleeve 6010A and a right sleeve 6010B that each include a visible design element 6011A and 6011B (eg, text, a slogan, a logo, a trademark, a part of a trademark, a name, a part of a name, and/or abbreviation). Visible design elements 6011A and 6011B can be related, as shown in Figure 124, to convey a message or present an image. As shown in Figures 125 and 126, object 6002 carries a centrally positioned visible design element 6013 (e.g. text, a slogan, a logo, a trademark, a part of a trademark, a name, a name part , and/or abbreviation), a 6014A left-hand visible design element (e.g., text, a slogan, a logo, a trademark, a part of a trademark, a name, a name part and/or abbreviation ) and a right side visible design element 6014B (e.g. text, a slogan, a logo, a trademark, a part of a trademark, a name, a part name and/or abbreviation). The exemplary design elements depicted are related in such a way as to convey a message as the sleeves 6010A and 6010B of the packaging system 6010 are removed from the object 6012. As shown, the visible design elements 6011A and 6011B, in the sleeves of the packaging system 6010A and 6010B, present a message or information about visible design elements 6013, 6014A, 6014B.
[00323] During a first Removal Phase, the centrally positioned design element 6013 becomes visible as sleeves 6010A and 6010B are separated. During a second removal phase depicted in Figure 125, left side visible design element 6014A and right side visible design element 6014B on object 6012 become partially visible as sleeves 6010A and 6010B are further separated. During the final removal phase depicted in Figure 126, left-hand visible design element 6014A and right-hand visible design element 6014B on object 6012 are completely visible and sleeves 6010A and 6010B have been completely removed from object 6012. In this regard, the packaging and object system, and the visible design element they carry convey a message or information that can be used as an advertising tool.
[00324] Figure 127 depicts a perspective view of the exemplary packaging system 6000 and object 6002 of Figures 120 to 123, as well as an exemplary removable cover in a manufacturing stage. The 6000 packaging system includes two parts, a left sleeve 6000A and a right sleeve 6000B, which may or may not be joined by a 6021 adhesive layer. The gloves 6000A and 6000B each include a top 6023A and 6023B and a part lower 6022A and 6022B, respectively. The 6023A and 6023B tops each include a 6001A and 6001B visible design element (eg, an image of a hand).
[00325] Object 6002 carries a centrally positioned 6003 visible design element (eg an image of a face), a left side visible design element 6004A (eg an image of a hand) and a design element visible from the right side 6004B (eg an image of a hand). In the exemplary embodiment depicted, visible design elements 6001A and 6001B are the same as left side visible design element 6004A and right side visible design element 6004B, although the size of the elements may be different.
[00326] Each side (i.e., the left and right sides) of the exemplary removable cover 1181 includes a primary flap 1184 (eg, a central end or free section) and a lateral free section 1185 that are not adhered to the lower surface of the object 6002. Removable cover 1181 also includes a center section 1185 (eg, a bonded section) and a bonded side section 1186 that is bonded to the bottom surface of object 6002.
[00327] Exemplary removable cover 1181 and packaging system 6000 may work together to facilitate placement of object 6002 and its receiving surface (eg, bottom surface). In this regard, each primary flap 1184 (i.e., on the left and right portions of the removable cover 1181) can be adhered to each respective lower portion 6022A or 6022B of the packaging system 6000 (e.g., via an adhesive layer).
[00328] In this regard, exemplary embodiments of the present invention encompass a removable cover that provides at least two step changes in resistance for cover removal along a force vector directed to the associated package, wherein the first change of step reveals a first portion of an image on the receiving surface, and the second step change reveals the remainder of the image on the receiving surface.
[00329] Figures 128 to 130 depict perspective views of another exemplary removable cover 1201 that achieves varied peel strength. Removable cover 1201 includes a primary tab 1204 (e.g., a center terminal or free section) and a body section 1205 (e.g., a center section or bonded section) that has an opening 1206. An adhesive layer 1301 is applied to the lower surface of body section 1205 and is exposed to objects on the upper surface of removable cover 1201 through opening 1206.
[00330] During removal, as a user grasps the primary flap 1204 and pulls the removable cover 1201 away from an object, initially the resistance to removal is determined by the interaction between the body section 1205 and the surface of the object, which may be a layer adhesive. In a later phase of peeling, the right side of opening 1206 and adhesive layer 1301 and their interaction with the object surface will affect peel strength. Typically, peel strength will increase because adhesive layer 1301 will provide greater strength. As more of the peelable cover 1201 is pulled away from the object (i.e., left to right as pictured), the progressively greater widthwise section of aperture 1206 and exposed adhesive layer 1301 will increase peel strength.
[00331] In this exemplary embodiment, the shape of opening 1206 will affect the way in which the peel strength varies during the peel process. In particular, the percentage of the width of the removable cover that the opening 1206 includes in a given cross-section taken at an angle that is 90 degrees from the axis along which the removable cover is removed (e.g., the cross-section in the direction of width as pictured) will affect the peel strength at a given peel stage. In this way, the depicted droplet opening 1206 will provide a pullout strength that gradually increases during the removal process and then, towards the end, decreases somewhat rapidly. It is within the scope of the present invention to employ other aperture shapes to achieve a desired variation in peel strength.
[00332] Figure 131 depicts a perspective view of another exemplary removable cover 1211 that achieves varied peel strength. Removable cover 1211 includes a primary tab 1214 and a body section 1215. As shown, a shaped adhesive strip 1311 can be applied to the body section 1215. The upper surface of the body section 1215 and the shaped adhesive strip 1311 are typically placed on a receiving surface (eg, an adhesive layer) of an object.
[00333] During removal, as a user grasps the primary flap 1214 and pulls the removable cover 1211 away from an object, initially the resistance to removal is determined by the interaction between the body section 1215 and the surface of the object, which can be a adhesive layer. At a later stage of peeling, the formed adhesive strip 1311 and its interaction with the object surface will affect peel strength. Typically, peel strength will increase because the shaped adhesive strip 1311 will provide greater strength. As more of the peelable cover 1211 is pulled away from the object (i.e., right to left as pictured), the progressively larger widthwise section of the shaped adhesive strip 1311 will increase the resistance to peeling.
[00334] In this exemplary embodiment, the shape of adhesive strip 1311 will affect the way in which the peel strength varies during the peel process. In particular, the percentage of the width of the removable cover that the shaped adhesive strip 1311 includes in a given cross-section taken at an angle that is 90 degrees from the geometric axis along which the removable cover is removed (e.g., the cross-section in the width direction as pictured) will affect the peel strength at a given peel phase. In this way, the tear-shaped adhesive strip pictured 1311 will provide a peel strength that gradually increases during the peeling process and then, towards the edge, decreases somewhat rapidly. It is within the scope of the present invention to employ other formats of adhesive strips to achieve a desired variation in peel strength.
[00335] Figure 132 depicts a perspective view of yet another exemplary removable cover 1221 that achieves varied peel strength. Removable cover 1221 includes a primary flap 1224 and a body section 1225. As shown, body section 1225 may include a shaped skin zone 1226. The upper surface of body section 1225 and shaped skin zone 1226 are typically placed on a receiving surface (eg, an adhesive layer) of an object. As pictured, body section 1225 may have a different coating than shaped coating zone 1226. Coatings may be release coatings (eg, a siliconized coating), but in this exemplary embodiment, the coatings are different and provide two strengths different to removal when combined with an adhesive layer on an object.
[00336] During removal, as a user grasps the primary flap 1224 and pulls the removable cover 1221 away from an object, initially the resistance to removal is determined by the interaction between the body section 1225 and the surface of the object, which can be an adhesive layer. At a later stage of peeling, the shaped coating zone 1226 and its interaction with the object surface will affect peel strength. Typically, peel strength will increase because the shaped coating zone 1226 will provide greater strength. As more of the peelable cover 1211 is separated from the object (i.e., right to left as pictured), the progressively larger widthwise section of the shaped liner zone 1226 will increase the resistance to peeling.
[00337] In this exemplary embodiment, the shape of the coating zone 1226 will affect the way in which the peel strength varies during the peel process. In particular, the percentage of the width of the removable covering that the shaped covering zone 1226 includes in a given cross-section taken at an angle that is 90 degrees from the geometric axis along which the removable covering is removed (e.g., the cross-section widthwise as pictured) will affect the peel strength at a given peel phase. In this way, the depicted drop-shaped coating zone 1226 will provide a peel strength that gradually increases during the peeling process and then, towards the edge, decreases somewhat rapidly. It is within the scope of the present invention to employ other shapes of coating zones to achieve a desired variation in peel strength.
[00338] Figure 133 depicts an aerial view of an exemplary removable cover 1231 that achieves varied peel strength. Removable cover 1231 includes a body section 1235 and a shaped coating zone 1236 that has greater peel strength than body section 1235 (e.g., through adhesive differences and/or coating release agent differences) . During removal, the upper end of the removable cover 1231 is initially removed from an object.
[00339] The application force required to remove the exemplary removable cover 1231 from an object at a given cross-section taken at an angle that is 90 degrees from the axis along which the removable cover is removed (e.g., the cross-section widthwise as pictured) can be determined by (i) measuring the widths A, B, and C of the cross-section segments of the body section and shaped casing zone, (ii) multiplying the measured widths by a relative strength factor , and (iii) adding them. For example, assuming shaped casing zone 1236 has a peel strength that is twice the peel strength provided by body section 1235, the application force required to remove exemplary peelable cover 1231 from an object at a given cut. transverse is given by: F = 1A + 2B + 1C.
[00340] In this regard, Figure 134 graphically depicts the application force or resistance required to remove the exemplary removable cover 1231 from an object as a function of distance along the geometric axis of detachment (i.e., the geometric axis to the along which the removable cover is removed). As shown, the strength initially gradually increases, then briefly decreases in the narrow lower section of the shaped coating zone 1236. The brief decrease in strength alerts or signals a user that the removable cover 1231 is nearing complete removal. Resistance then increases at the end of the removal process to facilitate placement of the object.
[00341] Figure 135 depicts a top view of another exemplary removable cover 1241 that achieves varied peel strength. Removable cover 1241 includes a body section 1245 and a shaped coating zone 1246 that has a lower peel strength than body section 1245 (e.g., through adhesive differences and/or coating release agent differences) . During removal, the upper end of the removable cover 1241 is initially removed from an object.
[00342] The application force required to remove the exemplary removable cover 1241 from an object at a given cross-section taken at an angle that is 90 degrees from the axis along which the removable cover is removed (e.g., the cross-section widthwise as pictured) can be determined by (i) measuring the widths A, B, and C of the body section cross-section segments and shaped casing zone, (ii) multiplying the measured widths by a relative strength factor , and (iii) adding them. For example, assuming shaped casing zone 1246 has a peel strength that is one-third of the peel strength provided by body section 1245, the application force required to remove exemplary peelable cover 1241 from an object at a given cut. transverse is given by: F = 3A + 1B + 3C.
[00343] In this regard, Figure 136 graphically depicts the application force or resistance required to remove the exemplary removable cover 1241 from an object as a function of distance along the geometric axis of detachment (i.e., the geometric axis to the along which the removable cover is removed). As shown, the strength gradually increases, and then sharply decreases in the rapidly enlarging section of the shaped coating zone 1246 at the end of the removable cover 1241. The decrease in strength at the peel-off end can facilitate placement of the object.
[00344] Figures 137 to 140 depict perspective views of an exemplary removable cover 1251 during different stages of removal. Exemplary removable cover 1251 includes a primary tab 1254, a body section 1255, and a mixed adhesion zone 1256. The varied adhesion zone has a different peel strength than the body section 1255, which can be achieved by increasing or decrease in adhesive strength, different release coatings, or a change in texture. Figure 137 depicts the removable cover 1251 as if applied to an object.
[00345] Figure 138 depicts the removable cover 1251 in an early removal phase. As shown, a first portion of the varying adhesion zone 1256 has been separated and extends downwardly from the adhesion edge 1259 with the portion of the removable cover 1251 that has been removed. Adhesion edge 1259 effectively defines the boundary between the removable cover section 1251 that has been removed and the removable cover section 1251 that is still adhered to an object. Adhesion edge 1259 is typically a cross-section taken at an angle that is 90 degrees from the axis along which the removable cover is removed. Adhesion edge 1259 may not be exactly perpendicular to the axis along which the removable cover is removed because of inaccurate removal by a user.
[00346] Figure 139 depicts the removable cover 1251 in an additional removal phase. As shown, a larger portion of the varied adhesion zone 1256 has been separated and extends downwardly from the adhesion edge 1259 with the portion of the removable cover 1251 that has been removed. As adhesion edge 1259 in Figure 139 includes a greater percentage of varying adhesion zone 1256 than adhesion edge 1259 in Figure 138, the peel phase shown in Figure 139 has a different peel strength than the peel stage shown in Figure 138 (i.e. increased or reduced peel strength depending on the relative peel strengths between body section 1255 and varying adhesion zone 1256).
[00347] Figure 140 depicts the removable cover 1251 in yet another Removal Phase. As shown, an even larger portion of the varying adhesion zone 1256 has been separated and extends downwardly from the adhesion edge 1259 with the portion of the removable cover 1251 that has been removed. As adhesion edge 1259 in Figure 140 includes a different percentage of varying adhesion zone 1256 than adhesion edge 1259 in Figure 139, the peel stage shown in Figure 140 has a different peel strength than the peel stage shown in Figure 139 (i.e. increased or decreased peel strength depending on the relative peel strengths between body section 1255 and varying adhesion zone 1256).
[00348] Figures 141 to 144 depict perspective views of an exemplary removable cover 1261 during different Phases of removal from an exemplary object 1263. Exemplary removable cover 1261 includes a primary flap 1264 and a body section 1265. The object Exemplary peelable 1263 includes a receiving surface 1262 (e.g., an adhesive layer) bearing a varying adhesion region 1266. The varying adhesion region 1266 has a different peel strength than the receiving surface 1262, which can be achieved by an increase or decrease in adhesive strength, different release coatings, or a change in texture.
[00349] Figure 141 depicts the exemplary removable cover 1261 and exemplary object before the two are adhered as shown in Figure 142. Figure 143 depicts the removable cover 1261 in a removal phase. As shown, a first portion of the body section 1265 has been separated from the object receiving surface 1262 and extends downwardly from the adhesion edge 1269. The adhesion edge 1269 effectively defines the boundary between the section. of the removable cover 1261 that has been removed and the section of the removable cover 1261 that is still adhered to the object 1263. The adhesion edge 1269 is typically a cross-section taken at an angle that is 90 degrees to the geometric axis along which the removable cover is removed. Adhesion edge 1269 may not be exactly perpendicular to the axis along which the removable cover is removed because of inaccurate removal by a user.
[00350] Figure 144 depicts the removable cover 1261 in an additional removal phase. As shown, a smaller portion of the body section 1265 is in contact with the varying adhesion zone 1266 and the majority of the body section 1265 extends downward from the adhesion edge 1269. in Figure 143 including a greater percentage of the varying adhesion zone 1266 than the adhesion edge 1269 in Figure 144, the peel step shown in Figure 143 has a different peel strength than the peel stage shown in Figure 144 (i.e., strength to increased or decreased peel depending on relative peel strengths between body section 1265 and varying adhesion zone 1256).
[00351] A comparison of the exemplary embodiments in Figures 137 to 140 and Figures 141 to 144 shows that variation in peel strength can be achieved using a varied adhesion zone on a removable cover (i.e., as in Figures 137 to 140) or on an object (ie, as in Figures 141 to 144). Additionally, combinations of these two exemplary embodiments (i.e. varying adhesion zones on both the peelable cover and the object) can also be employed to achieve a desired variation in peel strength.
[00352] Figure 145 depicts an aerial view of an exemplary removable cover and an object 110, and Figure 146 depicts a side view of the exemplary removable cover and object 110. The object includes a body portion 111, a central area 112 ( for example, a center pad) and two end portions 114 and 116 on the center zone side 112. The removable cover portions are below the object 110 and are therefore shown by dotted lines in the aerial view of Figure 145. The cover Removable includes a first bonded section 120 and a second bonded section 122 that are bonded to the object 110 (e.g., by means of adhesive layers 117 and 118 as shown in Figure 146). The removable cover also includes two lugs 140 and 141 that are respectively connected to the first bonded section 120 and the second bonded section 122 at their central ends (i.e., central with respect to object 110). The two handles 140 and 141 extend upward from the underside of the object 110 and around the object 110. As pictured, the handles 140 and 141 are positioned around the center 112 of the object. That said, handles 140 and 141 can be positioned anywhere along the length of the removable cover and/or the object 110. The handles 140 and 141 facilitate removal of the removable cover from the object 110. For example, the handles 140 and 141 can be pulled in the direction of the arrows shown in Figure 146. Additionally, the handles 140 and 141 allow a user to remove the removable cover from the object 110 and apply the object 110 to a surface without accessing or manipulating the side of the object 110 that will be adhered to the surface. For ease of description, some of the components of the exemplary removable cover and object 110 are not shown in Figures 147 to 149.
[00353] In this regard, Figure 147 depicts a side view of the exemplary removable cover of Figures 145 and 146 in a phase of removing the object 110. As pictured, handles 140 and 141 can be pulled out. Initially, the peel strength is relatively low as the lugs 140 and 141 move the first bonded section 120 and the second bonded section 121 away from the center 112, which typically do not include an adhesive layer. Peel strength then increases as lugs 140 and 141 move first bonded section 120 and second bonded section 121 away from adhesive layers 117 and 118 (shown in Figure 146 but not in Figure 147). Thus, the central zone 112 is exposed and can be applied to a surface (eg, a patient's skin) as shown in Figure 148.
[00354] Figure 148 depicts a side view of the exemplary removable cover of Figures 145 and 146 in a phase of removing an object 110 and a phase of applying the object to a surface 129. As pictured, the handles 140 and 141 move the first bonded section 120 and second bonded section 121 additionally adhesive layers 117 and 118 (shown in Figure 146 but not in Figure 148) and object 110 is applied to a surface 129.
[00355] As depicted in Figure 149, handles 140 and 141 can be further pulled to remove the removable cover from object 110, and adhesive layers 117 and 118 (shown in Figure 146 but not in Figure 149) can adhere to the surface 129 which holds the object 110 in position. Any of the previously described mechanisms for a change or variation in resistance can be used in conjunction with this exemplary modality.
[00356] Figure 150 depicts an aerial view of an exemplary removable cover and an object 210, and Figure 151 depicts a side view of the exemplary removable cover and object 210. Object 201 includes a body section 211, a central zone 212, two end sections 214 and 216 and a central bridge 205. The removable cover includes a first adhered section 220 and a section adhered to section 222 which are adhered to the object 210 (e.g., through an adhesive layer). The first bonded section 220 and the section bonded section 222 each include a tab at their respective ends closest to the center of object 210 that facilitates removal of object 210. Other exemplary embodiments, however, may not include such tabs . Alternatively, other interlocking tab mechanisms (eg adhesive layers, pin and hole mechanism, slit and tab mechanism) can be used. Typically, the ends of the first adhered section 220 and the section adhered to the section 222 that are closer to the center of the object 210 are not adhered to the object 210.
The removable cover also includes interlock extension sections 242 and 243. As shown, interlock extension sections 242 and 243 include complementary notches that lock together. The interlocking nature of the interlocking extension sections 242 and 243 can be achieved using other features or designs that provide different degrees or variants of pre-tensioning the object 210 consistently prior to application to a surface (eg a wound) . For ease of description, some of the components of the exemplary removable cover and object 210 are not shown in Figures 152 through 154.
[00358] Figure 152 depicts a side view of the exemplary removable cover of Figures 150 and 151 in a phase of preparation of the removable cover and object 210 for application to a surface. As shown, the ends of the removable cover and object 210 have been folded up (ie, away from the side of the object to be applied to a surface). The first bonded section 220 and the section bonded section 222 have been moved away from the central bridge 205. In Figure 153, the ends of the removable cover and object 210 have been further folded up and the interlocking extension sections 242 and 243 have been locked between themselves. After the interlocking of the interlocking extension sections 242 and 243, the user can position the object 210 including the center bridge 205 over the surface (eg including a wound as shown). The first adhered section 220 and the section adhered to section 222 have been moved away from the object 210 even further than in Figure 152, at the same time exposing a larger section of an adhesive layer.
[00359] Figure 154 depicts the object 210 including the central bridge 205 as applied to the surface. Interlock extension sections 242 and 243 have been released from each other and bridge 205 provides tension across the surface. Typically, an adhesive on the object 210 and/or the bridge 205 adheres the object 201 to the surface. The first adhered section 220 and the section adhered to the section 222 can be removed from the object 210 and the two end sections 214 and 216 can be adhered to the surface (for example, through an adhesive layer). The sections of the first adhered section 220 and the section adhered to the section 222 that have been moved away from the object 210 as a result of the application process as depicted in Figures 152 to 154 can function as a tab for subsequent complete removal of the first adhered section 220 and the section adhered to section 222 of object 210.
