"METHOD FOR FORMING A PACKAGE FROM A RIGID OR SEMI-RIGID PORTION AND A POLYMERIC TOP" BACKGROUND OF THE REVELATION
This application claims priority in accordance with 35 USC §119 (e) of provisional patent application serial number 61 / 249,852, filed on October 8, 2009 and provisional patent application serial number 61 / 298,429, filed on January 26 2010, whose contents of both orders are fully incorporated by reference.
FIELD OF REVELATION The present disclosure relates to a method and apparatus for producing a package with a cardboard box type container made of paper, cardboard, chipboard, or similar rigid or semi-rigid material having attached an upper section to it. resealable made of plastic, polymer or other flexible material, the resealable structure is typically a zipper, but not limited to it. The present disclosure similarly refers to the resulting package.
DESCRIPTION OF THE PREVIOUS TECHNIQUE
In the prior art, it is known to manufacture flexible resealable plastic bags for the sale of foodstuffs or other consumer products. Bags or packages, while well suited for their intended uses, typically have not been used for food products that would be easily crushed or damaged during transport. In addition, such bags or packaging may result in inefficiencies in storage, transportation and presentation.
Similarly, traditional cardboard boxes are well known for packaging and marketing well-established products such as cereals. However, these boxes are typically heavy and require an inner waxed paper or similar coating, which is typically tearable and therefore cannot be resealed and does not protect the contents after initial opening. This increases manufacturing costs and typically does not allow the package to be completely filled with the product, thus resulting in inefficiencies in space, which increases the costs of storage, transportation and product presentation. Therefore, many of these traditional cardboard boxes, particularly those with a tearable plastic liner, have been less satisfactory in their ability to be closed again.
There have been several attempts with packages to address these deficiencies, but none have been completely satisfactory. These attempts include those disclosed in United States Patent No. 7,524,111 entitled "Rigid-Bottomed Resealable Bag with Handles", issued on April 28, 2009 to Williams; United States Patent No. 7,207,716 entitled "Flexible Container Having Flat Walls", issued on April 24, 2007 to Buchanan; United States Patent No. 7,160,029 entitled "Enclosure for Resealing a Package and Method Therefor", issued on January 9, 2007 to Bein; United States Patent No. 6,908,422 entitled "Reclosable Packaging Bag and Method for Manufacturing Same", issued on June 21, 2005 to Ichikawa and others; United States Patent No. 6,110,512 entitled "Package and Merchandiser", issued on August 29, 2000 to Teasdale; United States Patent No. 6,063,416 entitled "Proce-dure and Package to Enable Peg Display of Food Pouch in Tent-Style Paperboard Carton", issued on May 16, 2000 to Teasdale and others; United States Patent No. 4,691,373 entitled "Zipper Closure with Unitary Adhesive Cover Sheet", issued on September 1, 1987 to Ausnit; and U.S. Published Patent Application No. 2005/0194386, entitled "Zipper Box Covers" published September 8, 2005 for Shai; and Japanese Patent No. 2002104511 entitled "Bag-in-Carton", published on April 10, 2002 for Makoto et al.
SUMMARY AND OBJECTIVES OF THE REVELATION
Therefore, an objective of the present disclosure is to provide a resealable package that in rigid walls thus providing a high capacity, space efficient package with a flat printing surface thus providing protection for the packaging of delicate products or that can be crushed.
Therefore, an additional objective of the present invention is to provide a package that is lightweight and that can typically be closed again.
These and other objectives are achieved by means of the present disclosure by providing a package, together with a method and apparatus for its production, which includes a rigid or semi-rigid container of the cardboard box type and, attached to it, a flexible upper part of plastic, polymer or similar, typically with a resealable zipper configuration, but not limited to it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, in detail, in which similar numerals indicate similar elements across all the various views, it can be seen that Figure 1 is a perspective view of an embodiment of the package 10 of the present disclosure. The package 10 includes a rigid, semi-rigid or fibrous cardboard box type container 12, typically with a central layer 164 (Figure 3B) made of a paper product such as fiber board or chipboard and an inner surface 166 with a oxygen barrier and moisture barrier and poly-coated outer layer 162, but is not limited to this (hereinafter referred to collectively as a "semi-rigid container"). The semi-rigid container 12 is typically initially provided in a flat configuration as shown in Figure 3A with an open top or mouth 14 and an open bottom 16. Package 10 further includes a plastic or polymeric upper part 18 (typically applied by heat, adhesive or glue) that includes first and second side walls 20, 22 and a resealable (or lockable) device 24, illustrated as a zipper with first and second interconnecting profiles 25, 27 (see Figure 6B), but is not limited to them. Other examples of resealable zippers include, but are not limited to, flanged zippers with opening edges, tamper-resistant flanged zippers, overt tampering zippers, flanged zippers with cursors (see Figure 23), flanged zippers without sliders, cord zippers (without flange), double zippers (see Figure 27I), multi-track zippers, zippers with a tear line, a zipper with flanges connected above the interconnecting elements, zippers with flanges connected below the interconnecting elements, leak-resistant zippers, zippers with a release seal, hinged zippers, zippers with spot seals, zippers with ocular marks, partially sealed zippers, zippers with shape maintenance characteristics, tightening pull zippers (ie, lower product opening resistance than consumer side opening resistance), zipper tape (especially for applications involving frozen food), hook and eyelet (ie Velcro®), resealable adhesives, perforated zipper tape, zipper tape laminated with a tear thread, zippers with a weakened resistance line, zippers with a wedge, zippers with a stabilization pillar, zippers with guide ribs, zippers with a compression pillar, and assemblies. These terms are known to those skilled in the art, and the corresponding zippers are disclosed in the incorporated patents by reference in full below. In addition, in some applications, a release seal may be a substitute for the resealable closure. Similarly, examples of the web from which the upper part 18 is manufactured include, but are not limited to, film with ocular marks, printed film (see Figure 22), film with cutouts, film with diagonal seals and film with tear lines. The upper part 18 is sealed or glued to the mouth 14 of the semi-rigid container 12. First and second transverse seals 21, 23 or other fastening methods are formed at the ends of the upper part 18 between the side walls 20, 22, immediately adjacent to the sense outwardly from the first and second folded edges (or first and second outer folds) 30, 32. The first and second transverse seals 21, 23 further typically include respective first and second incisions or side notches 31, 33 to remove material to aid in the subsequent folding of the upper part 18 to the position shown in Figure 2. Other shapes, such as single or multiple radius cutouts are also considered. It is noted that it is considered that some applications may fold the upper part 18 over the top of the package 10. However, it will be preferred in many applications that the zipper or zipper 24 is not folded 180 degrees. The upper part 18 can be made with biodegradable plastic. Additionally, in such an embodiment, the sealant for the semi-rigid container 12 would also be biodegradable.
As shown in Figure 3A, the semi-rigid container 12 is typically provided initially in a flat state with the front panel 13 and the rear panel 15. The semi-rigid container 12 is typically partially or completely poly-coated on the outer surface 162 ( Figure 3B), particularly in areas where heat sealing is required, such as the upper part of the semi-rigid container 12 where the upper part 18 is fixed, and the portions of the semi-rigid container 12 where the lower part is closed sealed before or after filling. Alternatively, adhesive is applied to the required areas and fixation is done by these adhesives. In addition, interior coating or lamination may include other materials required for the required barrier properties, including oxygen / moisture and airtight barriers. Although illustrated in Figure 3A (see Figure 22), the front and rear panels 13, 15 are typically printed including advertising and product information in the form of text and graphics on the outside, like most products commonly found in a grocery store or other retail outlet. The front panel 13 and the rear panel 15 are joined together by means of the first and second folded edges 30, 32 which ultimately become the front folds of the first and second reinforced sides 34, 36 of the semi-rigid container 12 in the expanded configuration or filled as shown in Figures 1 and 2. The front panel 13 of the semi-rigid container 12 further includes first and second vertical, inner, front folds 38, 40 which are adjacent inwardly from and parallel to the first and second folded edges 30, 32. In expanded or filled configurations as shown in Figures 1 and 2, first and second vertical, inner, front folds 38, 40 form the transition from the front surface 42 to the reinforced sides 34, 36. First and second vertical, inner, posterior folds 38 ', 40' similar are formed at the rear of the semi-rigid container 12, see Figures 5A and 5B, forming the transition from the s u posterior surface 43 for reinforced sides 34, 36. As shown in Figure 7, as well as in Figure 3A, the upper ends of the vertical folds 38, 38 ', 40, 40' can end in chamfered sections 39, 39 ', 41, 41 ', respectively, to prevent cracking of the material of the semi-rigid container 12 during folding and additionally to reduce the likelihood that the material of the semi-rigid container 12 forms a perforation point of the upper part material 18. Similarly, as shown in Figure 7, to prevent leakage between the upper part 18 (not shown in Figure 7) and the semi-rigid container 12, extra points of glue (indicated as "G") are provided on top of the first and second folded edges 30, 32 within the first and second reinforced sides 34, 36. Additionally, as the semi-rigid container 12 is typically formed of a single sheet of material with a splice 35 formed at the overlapping joint of the edges (shown in Figure 7 as occurring in the second inner vertical fold 40) an extra point of glue (indicated as "G") is provided at the top of the seam 35 to prevent leakage between the semi-rigid container 12 and the upper part 18 due to the thickness transition caused by amendment 35. Other modalities may use an even number (four or more) of panels.
Returning to Figure 3A, it can be seen that the first and the second horizontal folds 46, 48 are formed on the front panel 13 adjacent to the bottom 16. Similar interior horizontal fold 46 'is formed on the rear panel 15 of the semi-rigid container 12 , see Figures 5A, 5B. The first inner horizontal folds 46, 46 'are used to form the transition to the bottom surface 50 while the second inner horizontal fold 48 is used to form the fin seal 52 as shown in Figures 4A, 4B, 5A and 5B. A second horizontal fold is not shown on the rear panel 15, since typically, only one of the panels 13, 15 includes a second horizontal fold to help force the fin seal 52 to fold in a specific direction. As shown in the detail area of Figure 3A, the lower portions of the first and second vertical, inner, front folds 38, 40 form the respective first and second inwardly angled fold portions 139, 141. As shown in the detail area of Figure 3A, an angle typically 1-4 degrees, or preferably 2-3 degrees in most applications, is formed between the projection of the respective vertical, inner front folds 38, 40 (with substantially identical construction at the rear of the semi-container) rigid bending portions 139, 141, so that the inward bending portions 139, 141 tilt or turn towards the center of the semi-rigid container 12 as the portions angled inward bending directions 139, 141 approach the open bottom part 16. This aids in subsequent folding of semi-rigid container 12 into pack 10.
As additionally shown in Figure 3A, the first and second corresponding partially carved oval-shaped portions 47, 49 (typically cutting through a first layer of a coated surface or multiple laminates, however other similar methods, such as compression, are considered to be within of the notch definition) are formed with a vertical main axis in the semi-rigid container 12 immediately below the upper part 18, adjacent in an outward direction from the first and second vertical, inner front folds 38, 40 (thereby being located within reinforced sides after package 10 has been formed). During the formation of the package 10 from the semi-rigid container 12 and upper part 18, the first and second corresponding oval-shaped glue points 51, 53 (with a main horizontal axis) are placed on one front side of the upper part 18 , typically above the resealable or zipper fastener 24 and adjacent inwardly from the respective first and second transverse seals 21, 23. Additionally, a glue point 55 can be placed just below the midpoint of the upper edge of the upper part 18 Typically, hot melt glue is used, but other glues or adhesives may be applicable for various applications. During the formation of the package 10 from the semi-rigid container 12 and upper part 18, the upper part 18 is folded against the sides of the formed semi-rigid container 12 so that the first and the second oval-shaped glue points 51 , 53 cover and are glued or otherwise attached to the respective first and second partially carved oval-shaped portions 47, 49. Similarly, the glue point 55 adheres to the upper edge of the upper part 18 against the downwardly folded side wall 20. Subsequently, when the user lifts the upper part 18 in order to break the connection formed by the first and second oval shaped glue points 51, 53, typically only the first and second relatively well defined partially shaped oval portions 47, 49 they are pulled out of the semi-rigid container 12, with little or no tearing of bad-looking fibers. The first and second partially carved oval portions 47, 49 are typically provided only at the front of the semi-rigid container 12. Otherwise, the front and rear views of the semi-rigid container 12 are substantially identical. Alternatively, configurations that can be released can be used to attach the folded top to the sides of the formed semi-rigid container, such as, but not limited to, the releaseable adhesives, hook and loop (Velcro®), multiple strips, etc. . The first diagonal fold 54 extends from the intersection of the first inner vertical fold 38 and the first horizontal fold 46 to the intersection of the first folded edge 30 and the second horizontal fold 48. Similarly, the second diagonal fold 56 extends from the intersection of the second inner vertical fold 40 and first horizontal fold 46 until the intersection of the second folded edge 32 and the second horizontal fold 48. Additionally, as shown in Figure 3A, the lower corners are removed by means of the first and second lower cuts 57, 59 which extend diagonally from the respective ends of the second horizontal fold 48 to opposite ends of the lower part 16 of the semi-rigid container 12. This results in diagonal ends in the fin seal 52 as shown in Figure 4A. As shown in Figures 4B, 5B and 6B, first and second similar diagonal folds 54 ', 56' are formed on the rear panel 15 of the semi-rigid container 12. The first and second diagonal folds 54, 54 ', 56, 56' are required to form the diagonal edges of the first and second lower triangular flaps 58, 60, shown in the transient extended position in Figures 4A, 4B, 5A, 5B and shown in the level, sealed end position in Figures 1, 2, 6A and 6B.
Figures 6E and 6F illustrate an additional embodiment of the package 10, in which the first and second side walls 20, 22 can be provided as two separate sheets or a single sheet, and where the seal 119 joins the two separate sheets or is formed in a central location on the single sheet. The sidewall 20 includes a line of weakness 72 (which may include perforations, laser cut lines, tear strips, tear notches, linear tear lines, a peel seal, or similar structures, and can be configured as lines multiple) with first and second flanges 25 ', 27' of the zipper 24 extending over the fragility line 72 and sealed in the first side wall 20 on opposite sides of the fragility line 72. The zipper 24 further includes an opening zipper flange 123 that extends from it. In this position, the zipper 24 is placed in front of the upper part 18, in an off-center position rather than in a central position. A similar alternative embodiment would secure the zipper 24 inside the first side wall 20.
Figures 6G and 6H further illustrate an additional embodiment of the package 10 in which the side walls 20, 22 are provided as separate sheets (or alternatively, as a single sheet with an opening or tear line through it) and the flanking zipper. frost 24 with slider 70 is sealed on the outside (first flange 25 'sealed on the side wall 20 and a second flange 27' sealed on the side wall 22) thus allowing the consumer to operate the slider 70 to open the zipper 24 and thereby have access to the contents of package 10.
Figures 8A-14 illustrate methods and apparatus for producing the packages 10 of Figures 1-7. Figures 8A-G and 9A-C illustrate methods and apparatus for producing the unfilled flat packages of Figure 3A. Figure 8A (with many similar elements shown in the subsequent figures), a stack 11 of prefabricated or previously made folded semi-rigid containers 12 is provided to a sequential feeder 290 (another sequential feeder, such as an upstream conveyor or pick-and-place apparatus, can be substituted for stack 11 and sequential feeder 290), and semi-rigid containers 12 are fed sequentially in one direction of the machine by a servo driven conveyor 103. The weft material 12 is provided from a cart 100, with periodic ocular marks 104 (in some applications, cutouts in the weft material could be substitutes for ocular marks), the detection of which by the ocular mark detector 111 is used to synchronize the sequential feed of semi-rigid containers 112 by the sequential feeder 290 to the conveyor 103 (the alignment provided by the ocular marks 104 and the its detection is typically required only if the weft material 12 has graphics or other printing with defined locations for the beginning and the end of the adjacent upper parts, see Figure 22). Alternatively, the detection of periodic ocular marks 104 can be used to vary the speed of the conveyor 103 so that the semi-rigid containers are delivered with the correct alignment with respect to the weft material 102. The zipper material extension 22 is provided from the spool 200 and is sealed in the weft material extension 102 in the sealing and folding station 106 (the zipper material extension 202 can be configured without cursors, with pre-assembled cursors, or with cursors assembled by the assembly station optional cursor 204 just after the zipper is provided from the spool 200 or the mounting station 204 'can be located after the zipper material is attached to the weft material as shown in Figure 8A). This sealing can be done by attaching the first flange of an interlocking zipper material 202 to the unfolded weft material 102 and then securing the second flange after the weft material 102 is folded around the zipper material 202. Alternatively, the profiles separate, non-interlocking material from the zipper material 202 can be attached to the weft material 102 and the weft material 102 subsequently folded so that the profiles of the zipper material 202 are aligned and interconnected (see the alternative mode illustrated in spectrum in Figure 8B ). In another alternative, the interlocking zipper material 202 can be inserted between a folded weft material 102 and sealed or attached to it. In yet another embodiment of the method, the zipper is attached to separate weft materials. In such an embodiment, the zipper is either attached to a weave in an unblocked condition, one section for each weave, and subsequently, the zipper is aligned and interlocked or one side of an interlocked zipper material can be attached to a weave material . Then, the other weft material can be attached to the other side of the zipper material. In these embodiments, the zipper can be separated at a later stage to fill the semi-rigid container through the zipper. In addition, although the preferred method of fixing the zipper, weft, and semi-rigid containers together requires several steps, the same can be done in a smaller number of steps or even simultaneously.
Typically, releasable glue points (or other similar methods can be used) are applied to the weft material extension in the glue station 107 for the purpose of fixing the upper part 18 to the outside of the formed semi-rigid container 12. At the station of weft sealing (or fixing) 108, the weft extension 102 (with the zipper 202 attached to it) is folded (the side edges of which thus form the first and second side walls 20, 22 of the upper part 18 of Figures 1- 6) in order to contact the semi-rigid containers 12. The lateral edges of the weft material 102 are glued, sealed or otherwise fixed to the panels, front and rear, 13 and 15, of the semi-rigid container 12 via the weft sealing or fixing station 108. Sealing station 108 typically includes compression rollers and a heated bar on both sides of the weft. The sealing station can include multiple heated sealing bars, in which the semi-rigid container 12, with the upper part 18 in position, passes through these heated bars with little or no contact pressure. After each set of sealing bars, the container 12 and the upper part 18 pass through the compression rollers. The compression rollers establish the film / film seal (i.e., transverse seals 21, 23) between the semi-rigid containers 12 and the film / container seal on the containers 12. These compression rollers can be free-rotating or triggered. In addition, it has been found that by pre-tensioning the film of the upper part 18 during sealing, the package 10 becomes more rigid. The semi-rigid containers 12 with the weft material 102 fixed (with the zipper material 202, in turn, fixed to the weft material 102) moves towards the machine. A transverse seal 110 typically with three transverse sealing bars 112, 114, 116 (see Figure 11) alternately moves so that it momentarily moves towards the machine, tracking the movement of semi-rigid containers 12 and weft material 102 (with the zipper material 202 attached thereto), and engages the weft material 102 so that a first transverse seal 21 and second adjacent transverse seal 23 of an adjacent package are simultaneously formed in three gaps between packages, successively typically without the need to slow or stop the weft material displacement 102. The use of multiple transverse sealing bars (typically ultrasonic welding, but may include heat welding) in conjunction with the synchronized displacement with the weft material 102 allows an extended residence time, thus improving sealing qualities, while maintaining high production rates. In some embodiments, a greater or lesser number of transverse sealing bars can be implemented. The transverse seal 110 then moves in the opposite direction from the machine direction to position itself for the transverse sealing operation with three gaps between packages, successive or consecutive. Transverse sealing bars 112, 114, 116 typically include a reverse serrated ultrasonic tube and a reverse serrated ultrasonic anvil as shown in Figure 10. The reverse spiral surface creates several small receptacles for polymeric or similar material to flow during sealing or welding -range of the transverse seals 21, 23. This produces aesthetically pleasing and high-quality transverse seals in half the time of the heat and pressure sealing. This also typically removes the ambient heat that damages the film during long machine downtime. Figures 8A-G and 9A-C illustrate the method and apparatus for fixing the zipper web material on the outside of folded semi-rigid containers 12. However, such a zipper material can be fixed inside the semi-rigid containers 12 In such an embodiment, the edges 30, 32 of the reinforcements 34, 36 are slid over a required distance, and the zipper weft material is inserted between the separate upper portions of the reinforcements 34, 36 and attached to them and to the panels 13, 15. Alternatively, as shown in Figure 6D, panels 13, 15 (as well as reinforcements 34, 36) are provided with upward facing flaps 13 ', 15' between and into which the zipper weft material forms the part upper 18 is fixed as in Figure 3C. The weft material 102 in the gaps between packages is then cut through the cutting station 120, resulting in the flat and unfilled packages 10 of Figure 3A. Alternatively, instead of cutting, perforations can be made in the transverse seals by station 120, thus leaving the packages in a concatenated chain. Figure 8B shows a similar method and apparatus, in which no ocean mark is provided on the weft material 102 (typically because no graphics are provided on the weft material 102 that would require crucial alignment) and where the conveyor 103 is a chain servo-driven with periodically spaced adjustable lugs 105 to engage the rear edges of the semi-rigid containers 12 thus ensuring exact spacing of the semi-rigid containers 12. In addition, in Figure 8B, in spectrum, a second 200B zipper material headset, wherein source 200 would include a first interconnectable profile and source 200B would include a second interconnectable profile. The separate, non-interlocking profiles of the zipper material 202 can be attached to the weft material 102 and the weft material 102 subsequently folded so that the zipper material profiles 202 are aligned and interlocked.
As shown in Figure 8C, another alternative is to provide two separate weft sheets 102A, 102B. The zipper profiles 202A, 202B are supplied from respective reels 200A, 200B and sealed to the weft sheets 102A, 102B through the sealing stations 102A, 102B. The zipper profiles 202A and 202B are then aligned and joined together and the upper edges of the sheet web 102A, 102B sealed together in a joint and seal station 109. However, if at a later stage, the then formed container must be filled through the zipper, the top edges 102A and 102B are left unsealed.
As shown in Figure 8D, another alternative is to feed two weft sheets 102A, 102B and interlocking zipper 202 to the sealing station 106 in which a first zipper profile 202 is sealed in weft 102A and a second profile is sealed in weft 102B simultaneously or at a later station. Again, however, if at a later stage, the container then formed must be filled through the zipper, the upper edges 102A, 102B are left unsealed. The upper edges of the weft sheets 102A, 102B are then sealed together at the sealing station 109. Figure 27H is a representative cross section of what can be produced using this method and apparatus, showing, in particular, lines of fragility 72 or structure of similar opening (which may include perforations, laser cut lines, tear strips, hard tear notches, linear tear lines, a peeling seal, or similar structures, and can be configured as multiple lines) formed on the side walls 20, 22 thereby providing access to the zipper 24 after removal of the removable top portion 29. The receptacle 133 formed between the seals 135, 137 which may contain printed advertising or similar material 138 in that place is further illustrated in Figure 27H. This structure is similarly illustrated in Figure 22.
As shown in Figure 8E, segments of zipper material, resulting in discrete zippers 24, can be fed to the weft material extension 102 by the zipper feeder 206 as shown in Figure 17B resulting in a separate configuration. This can avoid having the zipper profile in the cross sections 21 and 23, but requires exact alignment of the zippers 24 with respect to a weft material 102. In this embodiment, the zipper segments can be applied to the weft material 102 in line with the weft direction or at an angle to it.
As shown in Figures 8F and 8G, stack 11 is implemented as a tank with containers 12 stacked vertically in it. Sequential feeder 290 is implemented as a conveyor belt. The conveyor belt 290 pulls a single container 12 through a feed port that allows only the thickness of a box to pass. The containers 12 are then engaged in a pass formed between the upper and lower drive conveyor belts 292, 294. The upper and lower drive conveyor belts, 292 and 294, are typically set at a different speed than the conveyor belt 290 for control the gap between successive containers 12. The edge of the containers 12 is detected by photodetector 296 that controls the operation of the glue point applicator 52 (similar to the one shown in Figure 9C) that applies glue points to the containers 12.
Figures 9A and 9B reveal methods and apparatus similar to those of Figures 8A and 8B, except that the weft material 102 is provided with the extension of the zipper material 202 already sealed thereon. If the weft material 102 is provided in a folded state, then folding within the illustrated apparatus is not required. Figure 9C discloses a method and equipment in which the weft material extension 102 is provided with the zipper extension 202 already fixed thereon. The weft material extension 102 is fed in the open configuration at a right angle (i.e., perpendicularly) to the direction of travel of the semi-rigid containers 12. The weft material extension 102 (with the zipper 202 attached) is then placed in alignment with the direction of travel of the semi-rigid containers via the roller 500. Glue dots are applied via the applicator 502 and guide rollers 504, 506, 508 fold the weft material 102 over the succession of semi-containers rigid 12.
Typically, the resulting upper part 18 comprises resealable weft closure material, in which the distance between the edges of the upper part 18, when separated, is greater than the distance between the edges of the sides of the semi-rigid container 12 when the container semi-rigid 12 is unfolded and formed (i.e., the distance between the first and second front inner vertical folds 38 and 40).
Figures 27A-27I illustrate various modalities or variations of the zipper 24, including profiles 25, 27 with respect to its attachment to the side, front and rear walls, 20 and 22 of the weft material 102, as well as different configurations of the weft material 102 as in Figures 27E and 27F. It should be noted that Figures 27A, 27E and 7F refer to constructions where the zipper is attached to the outside of the folded weft material (see also Figures 6E and 6G). As stated earlier, many different types of zippers can be used, such as hinged zippers, sliding zippers, flange-free (sliding) zippers and any of the zippers disclosed in United States Patent No. 6,360,513 entitled "Resealable Bag for Filling with Food Product (s) and Method ", for Strand and others; United States Patent No. 7,137,736 entitled "Closure Device for a Reclosable Pouch" to Pawloski; United States Patent No. 5,972,396 entitled "Fle-xible Package Having a Reclosable Zipper" to Jurgovan; United States Patent No. 6,030,122 entitled "Pinch-Grip Zipper" to Ramsey; United States Patent No. 6,347,885 entitled "Reclosable Package Having Zipper Closure, Slider Device and Tamper-Evident Structure" to Buchman; United States Patent No. 6,427,421 entitled "Me-thod of Manufacturing Recloseable Packages" to Belmont; United States Patent No. 4,846,585 entitled "Easy Open Bag Structure" to Boeckmann; United States Patent No. 4,874,257 entitled "Method of Forming a Closed Filled Bag, a Bag Construction and an Apparatus for Forming the Bag" to Inagaki; United States Patent No. 6,299,353 entitled "Zipper for Reclosable Container with Apertures Passing Through Female Profile" to Piechocki; United States Patent No. 6,955,465 entitled "Powder-Resistant Flexible Zipper For Reclosable Packaging" to Machacek; United States Patent No. 7,241,046 entitled "Watertight Closure for a Reclosable Package" to Piechocki; United States Patent No. 6,609,827 entitled "Bag Having Slider-Actuated Complementary Closure Strips and a Leakproofing Structure" to Oxen and others; United States Patent No. 3,325,084 entitled "Pressure Closable Fastener" to Ausnit; United States Patent No. Re. 34,554 entitled "Bags with Reclosable Plastic Fastener Having Automatic Sealing Gasket Means" for Ausnit; United States Patent No. 5,520,463 entitled "Foamed Zipper" to Tilman; United States Patent No. 4,787,880 entitled "Method of Making Extruded Zipper Strips and Bags Containing the Same" to Ausnit; United States Patent No. 6,177,172 entitled "Zippered Film and Bag" to Yeager; United States Patent No. 6,021,557 entitled "Process of Making a Zipper for a Reclosable Thermoplastic Bag" for Dais and others; United States Patent No. 7,478,950 entitled "Variable Alignment Slider Zipper for Reclosable Bags" for Plourde and others; United States Patent No. 4,925,316 entitled "Reclosable Bag Having an Outer Reclosable Zipper Type Closure and Inner Non-Reclosable Closure" to Van Erden and others; United States Patent No. 4,923,309 entitled "Tamper-Evident Package" to Van Erden; United States Patent No. 5,509,734 entitled "Wedge Activated Zipper" to Ausnit; United States Patent No. 4,736,451 entitled "Extruded Zipper Having Combination Stabilizing and Differential Opening Means" to Ausnit; United States Patent No. 5,412,924 entitled "Method of Making Reclosable Plastic Bags on a Form, Fill and Seal Machine" to Ausnit; United States Patent No. 3,959,856 entitled "Interlocking Separable Fastener" to Ausnit; United States Patent No. 6,131,370 entitled "Zipper Applied Across a Film in Transverse Direction" to Ausnit; United States Patent No. 6,863,754 entitled "Apparatus and Method for Manufacturing Reclosable Bags Using Zipper Tape Material" to Wright and others; United States Patent No. 6,290,392 entitled "Reclosable Plastic Bag with Deformable, Stay-Open Inlay" to Sandor; United States Patent No. 3,054,434 entitled "Bag Closure" to Ausnit; United States Patent No. 4,665,552 entitled "Zipper Equipped Bags and Method of and Means for Manually Filling and Separating Them" to Lems and others; United States Patent No. 5,902,427 entitled "Fastener Arrangement with Dual Purpose Cover Sheet" to Zinke and others; United States Patent No. 5,174,658 entitled "Self-Expanding and Reclosable Flexible Pouch" to Cook and others; United States Patent No. 6,827,491 entitled "Wide Open Feature for Reclosable Bags" to Kohl and others; United States Patent No. 6,899,460 entitled "Storage Bag with Openly Biased Mouth" to Turvey and others; and United States Patent No. 6,167,597 entitled "High Compression Zipper" to Malin, the contents of which are incorporated herein in full by reference.
A typical bottom filling method and equipment is shown in Figure 12. It is important to note that the filling apparatus and machinery shown in Figure 12 can be separated geographically or otherwise spatially separated from the machinery of package formation of Figures 8A-G and 9A-C. Forming and filling operations can take place at separate times and places, at the same time and in the same place. Forming and filling equipment and machinery can be on separate manufacturing lines or on an integrated manufacturing line. The package in Figure 3A (resulting from the method and apparatus of one of Figures 8A-G and 9A-C) is inverted. The forming device 300 opens the package 10 so that first and second inner vertical folds 38, 38 ', 40, 40' become the corners of the semi-rigid container 12, and a volume of product is created inside the semi-rigid container. rigid 12. This typically includes opposing forces on the semi-rigid container 12 next to the transverse seals 21, 23 as illustrated by the arrows labeled "F" on the far left of Figure 12. On the first sealer 302 (alternatively characterized as a releasable fastener) , as explained with respect to Figure 3A, first and second oval shaped glue points 51 and 53 are placed on one front side of the upper part 18 and the upper part 18 is folded so that the first and second points of glue oval shaped 51 and 53 cover and are glued or otherwise attached to the respective first and second partially carved oval portions 47 and 49. Mandrel 303, which can be reciprocating, can be used in combination with the first sealer 302 to guarantee a square shape of the semi-rigid container 12 and also to ensure secure bonding through points 51, 53. Alternatively, other methods of fixing the upper part 18 to the sides of the semi-container rigid format 12 can be used as previously described. Thereafter, the inverted package 10 is filled from the filling device 34. The first folder 306 folds along the first and second horizontal horizontal folds 46, 46 ', 48 and seals to form the fin seal 52 and triangular flaps 58 and 60 as shown in Figure 4A and 4B. The first folder 306 can be implemented with an inverted configuration of strip seal 310 shown in Figures 13 and 14. Polytetrafluoroethylene belts 312 and 313 grab the material of the fin seal 52 and heated seal bars 314 and 315 perform the sealing operation between the front and rear panels, 13 and 15, thus completing the fin seal 52. The first folder 306 can also use adhesive to close the bottom of package 10. The second fin 308 folds the fin seal 52 in level with package 10 and seals fin seal 52 on package 10. The third folder 309 seals the triangular flaps 58, 60 on the bottom of package 10 (shown in bold) or on the first and second reinforced sides 34, 36 of the container semi-rigid 12 (shown in spectrum). It may be preferred that the triangular flaps 58, 60 are sealed at the bottom of the package 10 for aesthetic purposes and to reduce the possibility for the consumer to open the bottom of the package 10. The semi-rigid container 12 may have different lower folding sections and different ways to fold these sections. In alternative embodiments, packages 10 are filled in at a later stage, or are kept in a continuous chain with perforated lines securing the transverse seals between adjacent packages 10 and stacked in a zigzagged configuration. In another alternative, the semi-rigid container 12 is not inverted. After the bottom of the container is formed, the semi-rigid container 12 is filled through the top as described below with reference to Figures 21A-C. Figure 15A illustrates, in spectrum, two possible positions of an optional handle 62 or 62 '. A handle 62 may be sealed or otherwise formed on the upper side side 18. Alternatively, a handle 62 'may be sealed or otherwise formed on the front panel 13 of the package 10. Figure 15B shows, in perspective, a portion extended upper 18 with an opening 63 therethrough, thus forming a loop. Figure 16 illustrates an embodiment of the upper part 18 in which the fold between the first and second side walls 20, 22 of the upper part 18 includes a line of fragility 72 (which may include perforations, laser cut lines, tear lines) , tear notches, linear tear films, or similar structures, and can be configured as multiple lines) instead of, or in conjunction with, lock 24. Similarly, element 72 can be implemented as a linear tear line. This provides an upper part 18 that can be opened by the consumer, but not closed again. Similarly, Figure 17A illustrates an embodiment of the upper part 18 in which side walls 20, 22 are provided as separate pieces with a peel seal 64 (typically pre-activated) between them. The element 64 could similarly be implemented as a tear tape or as a grab-and-go zipper. Figure 18 illustrates a cross section of a semi-rigid container embodiment 12 in which the front and rear panels 13 and 15 are joined at one end by means of the first reinforced side 34 and joined directly together at the other end at the point 36 'thus eliminating the second reinforced side 36 and providing a triangular cross section which can be advantageous for pouring. Figure 19A illustrates an embodiment of an upper part 18 in which the first and second side walls 20, 22 are sealed or otherwise joined together along a portion 66 of the upper edge, with a zipper 24, including first and second profiles 25, 27 providing a resealable closure along the rest of the top edge. Typically, the portion 66 is formed by sealing together a section of the zipper or the cross section 23 is extended through the upper part 18, leaving only a small section open for pouring out the content. Similarly, Figure 19B illustrates an upper part modality 18 in which a shortened zipper segment 24 ', configured as an assembly, is inserted into the seal 26 between the first and the second side wall 20, 22 in a configuration adapted for interconnection after the dumping of content. Figure 20 illustrates an embodiment of the upper part 18 including a portion of funnel 67 created by forming diagonal seals and cutouts for the double folded zipper film. Access to the funnel portion 67 is provided by the zipper 24. The funnel portion 67 would extend through the upper part 18 to dispense the product therefrom. Figure 21A illustrates an overfilled embodiment, in which the first side wall 20 of the upper part 18 is sealed, glued or attached to a semi-rigid container 12. Before sealing, gluing, or other fixing of the second side wall 22 from the top 18 to the semi-rigid container 12, the filling apparatus 40 inserts the contents into the package. Subsequently, the second side wall 22 is fixed or sealed back in the semi-rigid container 12 by means of sealer 402. Alternatively, as shown in Figure 21B, a zipper flange 27 'can be left unscrewed from its side wall corresponding 22 and the product is filled by the filling device between the flange 27 'and the side wall 22. Subsequently, the flange 27' and the side wall 22 are fixed together by means of the sealer 402. In an additional alternative embodiment shown in Figure 21C, the top foil of the upper part 18 is slit, the zipper (or resealable closure) 24 is opened, the product is introduced through the zipper 24 through the filling device 400, the zipper 24 is closed again and the edges upper part slits 18 are again sealed by sealer 402. However, if separate sheets of weft material are used as in Figure 8C, there is no need to split the top part of the super 18. Figure 22 illustrates an embodiment of the package 10 in which a straw opening 68 in the upper part 18, typically being initially sealed, but providing an easy opening for the container. Figure 22 further illustrates the structure of the removable upper portion 29 shown in Figure 27H. It is further illustrated in Figure 22 the attachment of a rigid support member 153 to the side of the second reinforced side 36, as well as the upper part structure illustrated and described with reference to Figure 27H. It is further illustrated in Figure 22 the print on the top and print on the cardboard box. Figure 23 illustrates an embodiment of the upper part 18 in which the resealable fastener 24 is implemented as a flange zipper with a slider 70. Additionally, the walls of the upper part 18 include a tear line 72 (typically implemented as a fragility line, such as perforations, laser notched lines, tear lines, tear notches, linear tear films, or similar structures, and can be configured as multiple lines) which is above the lockable closure 24 on the first and second transverse seal 21, 23 descending to the area between the top of the reclosable latch 24 and the sealing lines 74 joining the zipper flanges and the walls of the upper part 18. The slider 70 operates in a conventional manner, opening the zipper when moved in a first direction and closing the zipper when moved in a second direction, opposite the first direction. Figure 24 illustrates an embodiment in which the upper part 18 is held in place by a cover 80. The cover 80 includes rectangular top 82 with side walls 84 extending downwardly thereto. The rectangular shape of the lid 80 assists not only in reinforcing or strengthening the package 10, but also helps the package 10 to maintain a rectangular cross section. Similarly, Figure 25 illustrates an embodiment of package 10 with strip 86 keeping upper part 18 down. As previously described with reference to Figure 22, reinforced sides 35 or 36 can be provided with rigid support member 153. Top 82 and strip 86 can be fixed in a way that can be broken to the semi-rigid container 12, thus providing evidence of tampering, if removed. Figure 26 illustrates an embodiment of package 10 with a semi-rigid rectangular container 12 having four sides 90, 91, 92, 93 thus forming a square or rectangular shape that is free of reinforcements. The upper part 18 is glued, sealed or otherwise fixed to the flattened semi-rigid container 12 using previously described methods so that the transverse seal 21 is aligned with the corner or fold formed between the sides 90, 93 and the transverse seal 23 it is aligned with the corner or fold formed between sides 91 and 92 (formed opposite from the corner formed by sides 90, 93). This configuration allows the semi-rigid container 12, with the upper part 18 attached, to remain flat before filling (that is, the side walls 90 and 93 are pressed or folded flat against each other and the side walls 91, 92 are pressed or folded flat against each other), similar to the previously described modalities, however, without requiring reinforcements. In the open configuration, as shown in Figure 26, the zipper 24 extends diagonally across the open top of the semi-rigid container. Similar configurations could be achieved with packages with an even number of sides, greater than four.
Thus, the various objectives and advantages mentioned above are more effectively achieved. Although preferred embodiments of the invention have been revealed and described here in detail, it is to be understood that this invention is in no way limited and its scope should be determined by that of the appended claims.
