    CLOSING SET FOR A CONTAINER AND METHOD FOR MAKING A CLOSING FOR A CONTAINER. A container lock assembly includes a lock, an internal seal, and a radio frequency identification tag. The internal seal includes a first surface for engaging a container sealing surface, and a second opposite surface for engaging one of a support liner, a facing liner, an induction sealing liner, and a glued closure liner. The radio frequency identification tag includes an electrically attachable microprocessor with an antenna to receive, store and transmit digitized information. The internal seal can minimize the migration of fluids between the inner volume of the container and the outer one of a container when the inner seal is engaged with a sealing surface of the container. The radio frequency identification tag can be included in the closure set in the inner or outer volume of a container, or it can be incorporated into the internal seal, without the closure set electromagnetically interfering with the reception, storage or transmission of the digitized information.

    [001] This order claims the benefit of Orders No. 61 / 323,915, filed on April 14, 2010, and No. 61 / 360,550, filed on July 1, 2010, each of which is incorporated herein by reference in its wholeness. Field of the Invention
    [002] The invention relates to a container closure set that has an integral radio frequency identification tag. Description of the Related Art
    [003] Containers that can be closed are used for a variety of domestic and commercial products. Closures, such as screw-top and flip-top closures, hinged closures, dispensing closures, and the like, are installed after filling the container with a selected product. The closures may have a relatively simple structure, or they may include multilayer liners that provide selected functionality. A finished closure assembly may be a multipart assembly, and may include, for example, an outer closure with a hard hull adapted for resealable engagement with a container, one or more padding liners (also referred to as "cellulose paste"), sealable films, dehydrating inserts, and the like.
    [004] Container locking sets can be manufactured using different processes. A manufacturer specializing in fasteners can handle the entire raw material process for the final product. Alternatively, the manufacture of container lock assemblies can be handled by several specialized manufacturers. For example, fasteners can be produced and supplied as a stand-alone product by a manufacturer that specializes in injection molding. If the fasteners must use a liner, a liner manufacturer can produce the liners and install them in the closures. Alternatively, closures and liners may be manufactured and provided separately for the manufacturer of the product intended for the container or for a specialty container filling operation, which assembles the closures and liners, and installs the closure assemblies mounted on the filled containers. Closures and liners can also be provided separately for a closure assembly operation, which assembles and supplies finished closure assemblies to the product manufacturer or filling operation. The entire process from manufacturing to installation can involve numerous steps carried out by several different operators in several different locations, which can involve several packaging and transport steps. All of this can add to the cost finally paid by the end user, thus increasing the value of the product enclosed by a container and closure set.
    [005] Many products, such as pharmaceuticals, foodstuffs, personal care products, household chemicals, and the like, may require protection from air and moisture while in a container. It is known that a metallic liner, such as aluminum foil, is typically less permeable to air and moisture than a polymeric liner. Thus, closure sets may also include features that prevent the migration of air and moisture into the container.
    [006] Manufacturers, distributors, carriers, resellers, and / or end users may wish to monitor or identify containers at various points throughout the distribution process.
    [007] In addition, end users typically expect some assurance that the contents purchased from a container are as advertised and produced by the manufacturer. Thus, locking sets may also include features that prevent or signal unwanted or unauthorized access to the contents of the container. Specialized sealing liners, often referred to as "tamper-proof seals" or "tamper evident seals", can be installed over the opening of the filled container. Such fences are adapted so that the fence must be removed, destroyed, or distorted to obtain initial access to the content, thus indicating that the breach may have been carried out. However, tampering agents can replace or recreate a sealing liner so expertly that the mistake most likely may not be discovered.
    [008] Violation can be minimized by controlling the transport and storage of filled containers. Radio frequency identification ("RFID") tags can be used to track containers and provide information regarding the products transported in them, such as the name of the product, its location and date of manufacture, expiration data, an identification number , and the like. RFID tags typically consist of a microchip or microprocessor that can store such information, electrically coupled with an antenna. The antenna can receive an actuation signal from a remote transmitter and carry the signal to the microprocessor, to which the microprocessor can respond by transmitting information stored through the antenna to a remote reader. The microprocessor and the antenna can be mounted on a support substrate, which can include a label or enclosure, for extension along the outside of the container and / or closure assembly.
    [009] RFID tags are often manufactured by a specialized RFID tag manufacturer that purchases the substrate and microprocessor material, and attaches the antennas and microprocessors to the substrate. The label manufacturer can also add typically printed information about a product label to the substrate. The substrate / label can then be affixed to the outside of the container and / or closure assembly. Alternatively, the product manufacturer can print and attach the product label by incorporating RFID tags.
    [0010] RFID tags can also be pre-coded, non-coded, or omitted from the container and / or closure set. This can further complicate the manufacture of the container closure and filling assembly by requiring the manufacturer responsible for adding the RFID tags to the container and / or final closure assembly to perform additional operations on the RFID tags, such as encoding, verification, control quality, and the like. This can lead to inefficiencies and increased costs, and can complicate the customization of RFID tags.
    [0011] The positioning of the RFID tag under a closure assembly can improve protection of the tag during the shipping and handling process. However, if an RFID tag is to contact a metal liner, the tag may be rendered completely inoperative, or the operating radius of the RFID tag may be significantly reduced. Polymeric liners do not have this limitation. However, as discussed above, the higher permeability of polymeric liners can make their use undesirable.
    [0012] Composite ceilings were developed, which consist of a metallic antenna portion coupled with a microprocessor, and a polymeric portion to properly isolate the microprocessor and optimize the performance of the RFID tag. Although, in many cases, satisfactory RFID tag performance can be provided with this configuration, the composite liner is more permeable in those areas without a polymeric metal liner, effectively making the entire sealing liner relatively permeable, and thus invalidating the purpose of a liner metallic.
    [0013] The optimization of the resistance and fidelity of the transmission signal is dependent on the location of the RFID tag on or inside the container. There are benefits to be incorporated into an RFID tag on the sealing liner. However, sealing liner manufacturing methods may fail to accommodate satisfactory integration of the RFID tag with the sealing liner.
    [0014] Consequently, it would be advantageous to employ some means in addition to a sealing liner for the most effective protection against tampering. It would also be advantageous if such a means could easily provide automatic identification of a container and its contents to confirm that all containers in a shipment or batch are as expected for shipment, inventory control, customer order preparation, inspection of customer, and the like. In particular, automatic identification can comprise part of a control system that can be responsible for each individual container during its shipment from the manufacturer to the end user. In this way, both errors (for example, mislabelling) and intentional mistakes can be detected and corrected before a product reaches an end user. BRIEF DESCRIPTION OF THE INVENTION
    [0015] A container lock assembly includes a lock, an internal seal, and a radio frequency identification tag. The inner seal includes a first surface for engaging a container sealing surface, and a second opposite surface for engaging one of a support liner, a facing liner, an induction sealing liner, and a glued closure liner. The radio frequency identification tag includes an electrically attachable microprocessor with an antenna to receive, store, and transmit digitized information. The internal seal can minimize fluid migration between an inner volume of the container and an outer one of a container when the inner seal is engaged with a container sealing surface. The radio frequency identification tag can be included in the closure set within the inner volume of the outer container to a container, or can be incorporated into the inner seal, without the closure set interfering electromagnetically with the reception, storage, or transmission of information scanned.

DETAILED DESCRIPTION OF EXAMPLES OF EXAMPLE OF THE INVENTION
    [0017] Several modalities of examples of the invention described here share common elements. To the extent that a modality incorporates an element from another modality described here, the same reference character will identify each same element, unless otherwise indicated. In addition, an element of a modality having a configuration and / or function comparable to those of an element associated with another modality described here, must be considered to operate and / or functioning in the same way as that element associated with such another modality, and your description will not be repeated here, unless otherwise noted.
    [0018] The following terms used in this application are defined as:
    [0019] "Closure" - a structure or device used to close or seal a container, such as a bottle, flask, tube, and the like.
    [0020] "Support lining" - a compressible material, such as pulp or foamed polyethylene, to which a facing lining is affixed or adhered. This compressible material is typically held against the inner surface of the end wall of the closure, and compensates for any irregularities along the sealing surface.
    [0021] "Facing lining" - a lining material affixed to or attached to, or retained against, the support lining. The facing liner can act as a barrier to chemically reactive products, particularly when an induction sealing liner is not used.
    [0022] "Finished" - the configuration of a container opening, configured to accommodate a closure.
    [0023] "Gasket" - a lining applied between the sealing surface of a sealing lip and the closure. A gasket provides a complete seal, and does not need to be attached or attached to the closure.
    [0024] "Glued lining" - a lining affixed to the inner surface of the closing end wall by an adhesive, usually a hot-melt adhesive.
    [0025] "Induction sealing liner" - a specialized laminate containing a metal foil and a plastic heat-sealable film, which is used to hermetically seal a container opening using induction sealing technology.
    [0026] "Embedded part" - an electromagnetic device comprising a microchip and an antenna that can be programmed with information to identify an item on which the embedded part is affixed, transmits such information to a receiver, and receives additional information during its useful life operation of the embedded part. Also referred to as an "RFID tag".
    [0027] "Internal Seal" - a lining of sealing material applied over the opening of a container before or during the installation of a closure to minimize the migration of a substance into or out of the container, or violation of the contents of the container .
    [0028] "Lining" - a layer of paper, cork, foam, plastic, metal, and the like, which can be retained in a closure, to provide a flexible insert between the closure and the sealing surface of the container.
    [0029] "Sealable film" - a layer of material applied between the sealing surface of the sealing lip and an overlapping liner or closure. A sealable film can be adhesively or thermally attached to the sealing surface, and can be incorporated into a liner stock. The sealable film can be an internal seal.
    [0030] "Sealing surface" - the lip portion of the finish that makes contact with a sealing gasket, a sealing film, or a liner, and forms a seal.
    [0031] With reference now to the figures, and initially to figure 1, a first example embodiment according to the invention is illustrated, comprising a container set 10. The container set 10 can include a container 12, and a set of closure 14, which includes a resealable protective closure 15, adapted for coupling with container 12. Closure assembly 14 is exemplary, and may include alternative elements and / or configurations appropriate for a selected closure functionality. For example, the closure set can be configured for a single use or for repeated uses.
    [0032] The container 12 can have an opening 16 to provide access to an interior space 18, with a finish defined by a rim having a sealing surface 20. The closure 15 can be configured for proper alignment with the sealing surface 20 to facilitate sealing of opening 16. For example, closure 15 and container 12 can be adapted for screw-on coupling, snap-fit coupling, bayonet type coupling, and the like.
    [0033] Container 12 is illustrated as cylindrical, although it can have any configuration selected, such as square, octagonal and the like. The closure 15 is illustrated as cylindrical, although it can also have any configuration selected, which includes a configuration complementary to that of the container 12. Safety features can also be incorporated into the closure 15 to prevent unintended opening by young children.
    [0034] Figure 1 shows a first example embodiment of the closure assembly 14 interposed between the closure 15 and the container 12. The closure assembly 14 may include an internal seal 21, comprising a sealable film 22a and a foil 24 having a mounting flap 26, a radio frequency identification tag (hereinafter "RFID tag") 25, and overlapping insulation liner 40 somewhat analogous to a facing liner, to maintain the electromagnetic separation of the RFID tag 25 from the foil 24 , as described below. The various elements comprising the closure assembly 14 can be configured based on, for example, the item (s) to be contained, the environment in which the container will be present, the duration of storage of contents, protection against tampering, and the like. Closure assembly elements, such as a sealable film 22, a foil 24, an insulation liner 40, and other liners, can be manufactured from one or more materials having properties suitable for the intended purposes, such as aluminum, paper, cardboard, cardboard, polymers, resins and the like.
    [0035] The foil 24 is connected to the container opening 16 through the sealable film 22a. The sealable film 22a may comprise a bonding agent, such as a single or multiple constituent adhesive, which can be heat activated, or activated during an induction sealing or sealing process, to connect the foil 24 to opening 16. A sealable film 22a can be a separate component from the foil 24, or it can extend over a surface of the foil 24.
    [0036] An annular sealable film 22a extending only along the sealing surface 20 can be used with the foil 24 or another selected liner. Alternatively, a circular sealable film 22b (Figure 9) extending across the sealing surface 20 and over the opening 16 can be used with the foil 24 or another selected liner, with an annular portion of the circular sealable film 22b along the perimeter of the foil 24 connectable to the sealing surface 20. The sealing film 22b can extend along the lower surface 45 of the metal foil 24 to secure the metal foil 24 to the sealing surface 20. References here to a sealable film 22 should be intended to encompass an annular sealable film 22a or a circular sealable film 22b, unless otherwise indicated.
    [0037] To optimize manufacturing efficiencies, the sealable film can be laminated to the metal sheet to form a sheet or roll stock. Individual liners can then be cut from the stock for incorporation into a closure set.
    [0038] The sealable film 22 and the metallic sheet 24 can be joined to the sealing surface 20 by an induction heating process. Alternative display methods, such as solvent based adhesives, or hot plate bonding using a heat activated adhesive, can be used. The sealable film 22 can also be a material that is fusible to the sealing surface 20, such as a thermoplastic or thermostable, or a material that facilitates laser welding, ultrasonic welding, induction welding, and the like.
    [0039] The sealable film 22 can have dimensions complementary with the diameter and width of the sealing surface 20 for joining the sealable film 22 to the sealing surface 20. The sealable film / sealing surface can have sufficient strength in place to prevent removal of the RFID 25 tag without deformation or destruction. Consequently, the RFID tag 25 can be permanently affixed to the container 12 along the sealing surface 20, thus resulting in an evident tampering seal.
    [0040] The mounting flap 26 can include an insulation channel 36 forking the flap 26. The insulation channel 36 can be positioned anywhere on the mounting flap 26, but is shown to be positioned along a generally bilateral axis. longitudinally (not shown), which defines two generally symmetrical label fingers 32, 34. The insulation channel 36 can have a pre-selected length, generally starting, as shown in figure 2, at the ends of the label fingers 32, 34 and ending to allow the microprocessor 27 to be affixed to a pre-selected location 37 along the insulation channel 36. Part or all of the RFID tag 25 can have a multilayer configuration that includes one or more of a lining and / or the foil having appropriate properties for a selected container set configuration, a selected usage environment, or selected contents.
    [0041] The RFID tag 25 is illustrated in figure 2, and can comprise a generally circular metallic sheet 24 smoothly transitioning from a smaller arc to a mounting flap 26 radially outwardly 26. Both the metallic sheet 24 and the flap mounting elements 26 can be continuous, formed from the same blade, such as aluminum, having strength, durability, and electromagnetic properties appropriate for the purposes described here. The mounting flap 26 can generally be folded along the smaller arch to be located on the foil 24.
    [0042] The microprocessor 27 can be electromagnetically coupled to the mounting flap 26 through mounting contacts 28, 30, which extend from the microprocessor 27 to the label fingers 32, 34, respectively. The mounting contacts 28, 30 can be electromagnetically coupled to the metal sheet of the mounting flap 26 in an appropriate manner, such as with a welded connection, adhesives and the like. The microprocessor 27 can be positioned inside the isolation channel 36/37 to define a microprocessor bridge 38 that extends in the isolation channel 36. Except for the coupling of the contacts 28, 30 with the tag fingers 32, 34, the microprocessor 27 can be electromagnetically isolated from the label fingers 32, 34, and the metal foil 24. Consequently, the metal foil 24 and mounting flap 26 may comprise an antenna for microprocessor 27, electromagnetically isolated from microprocessor 27, except through the mounting contacts 28, 30.
    [0043] The microprocessor 27 may have appropriate storage capacity and performance characteristics for the purposes described here. The microprocessor 27 can be programmable to track containers and provide information regarding the products carried in it, such as the name of the product, its location and manufacturing data, an expiration data, an identification number, and the like, which can be significance to a manufacturer, carrier, distributor, wholesaler, reseller, or consumer. The microprocessor 27 can be selectively actuated by radio frequency signals from a transmitter (not shown) configured for that purpose, which includes a portable mobile transmitter, or a stationary transmitter. Microprocessor 27 can receive data from a transmitter, which microprocessor 27 can store, such as updating to the location of the container, the location and / or identity of the party currently in possession of the container, the current time and date, and the like. Radio frequency signals from a transmitter can also actuate microprocessor 27, which can, in response, send data stored on it to a receiver (not shown) via radio frequency signals.
    [0044] Referring again to figure 1, the overlapping insulation liner 40 may be a disk-like body, generally circular, made of a material, such as closed cell foam, providing electromagnetic insulation properties. The insulation liner 40 is shown in figure 1 in the middle between the RFID tag 25 and the lock 15.0 overlapping insulation liner 40 can be arranged on, and in non-fixed contact with, an upper surface of the foil 24. Alternatively, the liner insulation 40 can be attached to the metal sheet 24 by means of an adhesive or other suitable means to hold the insulation liner 40 in a selected position in relation to the metal sheet 24. With any configuration, the mounting flap 26 can be folded over the insulation liner 40 to extend over an overlapping surface 41 of insulation liner 40, maintaining electromagnetic insulation from microprocessor 27 in relation to the antenna / foil 24. The latch 15 can be joined over the insulation liner 40, the tag RFID 25, and opening 16 to protect the RFID 25 tag during shipping and handling.
    [0045] The microprocessor 27, in the configuration described above, can be fully functional due to its electromagnetic isolation from the metal sheet 24 starting with the moment when the closing assembly 14 is installed in the container 12 until the RFID tag 25 is removed . The RFID tag 25 can be removed from the container 12 after removing the closure 15, and then discarded, using the mounting flap 26 as a pull tab. If the end user removes the lock 15 to discover that the RFID tag 25 has been tampered with or removed, the end user may be alerted that the contents of the container set 10 may have been tampered with, and informed to take appropriate action.
    [0046] The RFID tag 25 can provide several necessary functions in a single sealing device. The opening 16 can be overlaid in its entirety by the foil 24, thus providing a seal that is virtually impermeable to liquids and gases. The storage life of the contents of a container set that incorporates the metal sheet can therefore be substantially increased over that of a container set that incorporates a polymeric film. The foil 24 can be easily affixed to the sealing surface 20 by one of several methods. At the same time, the RFID tag 25 may be available to provide critical information about the contents, such as the manufacturer, age, contents, visual description, and the like, using transmitters and receivers. In addition, the mounting flap 26 can serve as a pull tab, allowing a consumer to easily gain access to the contents of the container assembly 10.
    [0047] Referring now to figures 3 and 4, a second example embodiment of a lock assembly 14 and an RFID tag 25 are illustrated. The second embodiment of the RFID tag 25 is identical to the first embodiment, but the mounting flap 26 can be folded under the foil 24 and, consequently, uses a downward folded insulation liner 42. The downward folded insulation liner 42 can generally serve the same purpose as the overlapping insulation liner 40 and can be made of the same material as the overlapping insulation liner 40. However, the downward-folding insulation liner 42 may have a diameter that is not larger than the inner diameter of the sealing surface 20 to avoid interference with the adhesion of the sealable film 22 to the sealing surface 20.
    [0048] The folded down insulation liner 42 can be affixed to the underside of the foil 24 and / or the sealable film 22, thus defining a folded down surface 43. The mounting flap 26 can then be folded under the liner downward folding insulation 42 to extend along the downward folding surface 43. Subsequently, the metal sheet 24 and affixed insulation liner 42 can be sealed to the sealing surface 20, with the mounting flap 26 extending into the space interior 18. The latch 15 can be joined over the folded down insulation liner 42, the RFID tag 25, and the opening 16, to provide improved protection for the RFID tag 25.
    [0049] The configuration of the mounting flap 26 can be as exposed for the first RFID tag mode 25. The metal foil 24 and mounting flap 26 can be realized as an antenna for the microprocessor 27, which can be isolated from the foil metal 24 by the insulating liner folded down 42, except through the mounting contacts 28, 30.
    [0050] Figures 5 and 6 illustrate a third example embodiment of a closure assembly 14, which includes an RFID tag 25, generally as described for the first example embodiment, and an insulation pad folded down 44. The pillow downward folding insulation pad 44 is illustrated as comprising a straight "flap" affixed to the bottom side 45 of the foil 24, and is used in place of the downward folding insulation liner 42. The downward folded insulation pad 44 may have a size and configuration sufficient to isolate the microprocessor 27 from the metal sheet 24 when the mounting flap 26 is folded down. Optionally, the insulation pad 44 can be affixed to the top side of the foil 24 as an "folded over" insulation pad (not shown). The pad 44 can also take any shape, regular or irregular, any thickness, or any position on the foil 24, consistent with the functional and operational characteristics of an insulation liner as described here.
    [0051] The mounting flap 26 and RFID tag 25 can be folded so that the microprocessor 27 is in contact with a pad surface folded down 47 of the insulation pad 44 and thus electromagnetically isolated from the foil 24. A affixing the insulation pad 44 to the underside of the foil 24 can be carried out during the manufacture of the RFID tag 25, as opposed to incorporating the insulation pad 44 into the RFID tag 25 as a separate component of the locking assembly 14. The space required small of the insulation pad 44 can facilitate the affixing of the metal sheet 24 to the sealing surface 20, and the manufacture of the closure assembly 14, reducing the potential for the insulation pad 44 to contact the sealable film 22.
    [0052] Isolation pad 44, whether used as a folded-down or folded-up insulation pad, can also serve as a label to display information, such as dosing instructions, to a consumer who could have ignored the same information on the side of the container assembly 10.
    [0053] Figure 7 illustrates a fourth example embodiment of an RFID tag 46 which can be identical to RFID tag 25, except for a pair of opposite flap notches 60 along the side edges of the mounting flap 26. A frangible line 63 can connect the notches 60 to define a tear tab 62 comprising an end portion of the mounting tab 26 having the microprocessor 27. This can facilitate the removal of the microprocessor 27 from the rest of the RFID tag 46, thereby disabling the RFID tag 46 The mounting flap 26 can be a folded up or folded down configuration, as previously described here. Alternatively, the mounting flap 26 can extend along the interface between the container 12 and the closure 15 to project along the side of the container 12 away from the closure 15, thus facilitating the removal of the tear flap 62 prior to initial removal of the closure 15. Thus, the tear tab 62 can be removed by a consumer immediately upon purchasing the container assembly 10 and product contained therein. The tear tab 62 can be protected by a superimposed wrapper (not shown) affixed to, or enclosing, at least a portion of the container 12, which can be easily removed by a consumer to access the tear tab 62.
    [0054] Figure 8 illustrates a fifth example embodiment of an RFID tag 64 which may include a semicircular pull tab 48 coupled with metal foil 24. Metal foil 24 can be affixed to the sealing surface 20 of a container opening 16 through a sealable film 22, as previously described here. The foil 24 can be coupled with the pull tab 48 to allow the pull tab 48 to be folded over the foil 24 in a complementary arrangement thereto. The pull tab 48 may include an isolation channel 54 to accommodate a microprocessor bridge 56. An upwardly disc-like insulation liner 58 having appropriate electromagnetic insulation properties, size, configuration, and thickness, can be attached to the upper surface of the foil 24 so that the pull tab 48 and the microprocessor 27 can be folded over the insulation liner 58 adjacent to, but separate from, the foil 24.
    [0055] The pull tab 48 and metallic foil 24 can act as an antenna in a similar way to that exposed in relation to the first modality. Thus, the pull tab 48, which includes an electrically insulated microprocessor bridge 56, can form part of a seal that can be easily removed from the container 12, while operating as an RFID tag.
    [0056] With reference now to figure 9, a sixth example embodiment of a closure assembly 14 according to the invention is illustrated. The sixth embodiment is similar to the properties previously described, and includes the container 12, the closure 15, a sealable film 22b (the sealable films 22a, 22b can be used in the alternative), the metal sheet 24, a pull-tab lining 76 , and a support liner 78, also referred to as a "filler." Closure assembly 14 may include different elements than those shown in figure 9 depending on factors, for example, such as the relevant properties of the item (s) ) to be (are) contained, and the type (for example, humidity, breach) and degree of protection specified.
    [0057] The pull tab lining 76 may comprise a multilayer lining which incorporates a pull tab 82 for gripping by a user to remove the closure assembly 14 and gain access to the interior space 18 of the container 12. The flap lining of pull 76 can be interleaved with sealable film 22 and foil 24. Alternatively, the foil and sealable film can be integrated into the pull tab lining 76 to form a unitary lining having both pull tab and sealing features, the foil 24 can be omitted and replaced with an alternative material, such as support liner 78, a facing liner, or an internal seal, if tampering is an issue, but exposure of the contents of the container to fluids is not. The support liner 78 can be arranged between the pull-tab liner 76 and the lock 15. The support liner 78 can be fixedly incorporated in the lock 15, separate from the remaining elements of the lock assembly 14.
    [0058] Referring also to figure 13, the pull-tab lining 76 with a built-in RFID tag 80 can be manufactured from sheet stock or roll stock material 84. Stock material 84 can be supplied in rolls or sheets suitable for a continuous manufacturing process, and may include one or more of a substrate 86, which can selectively serve as a seal or inner liner, a sealable film material 88 which is located below substrate 86, and a tape pull tab 90, laminated together. The manufacturing process can include an RFID antenna production step, and a flip chip connection step to couple the microprocessors with antennas to produce an RFID 80 embedded part or tags. The process can also include a lamination step for laminate RFID 80 tags to form products.
    [0059] The RFID antenna production step may include one of several processes, such as acid etching of copper or aluminum, or printing with silver ink using screen printing, flexographic printing, engraving printing, or inkjet printing, on substrate 86. Antennas can also be produced by electrode-free plating, using screen printing, flexographic printing, gravure printing, or inkjet printing, to print a catalyst ink on a substrate 86, then depositing conductive metal on the plating catalyst without electrode.
    [0060] Antennas can be produced by electroplating, using silkscreen printing, flexography, engraving, or inkjet printing, to print a conductive ink on a substrate 86, then electroplating conductive metal on the conductive ink. The antenna production step can be followed by the flip chip connection step, to provide regularly spaced RFID 80 tags, incorporated in the stock material 84.
    [0061] A pull tab 90 of material, such as a polymer, a paper / polymer composite, a metallic / polymer composite, and the like, having a width somewhat less than the width of substrate 86, can be aligned longitudinally with substrate 86 and sealed to substrate 86 to form a pull tab 82 capable of rotating longitudinally around a pull tab hinge line 50 away from substrate 86, as shown in figure 10. Alternatively, the tape pull tab 90 can have a width equal to the width of substrate 86, with [1/2] the width of pull tab tape 90 longitudinally affixed to substrate 86 to form hinged pull tab 82. In any case, RFID tags they can be joined to form sheet stock or roll stock material 84, such as the pull tab tape 90, instead of the substrate material. The pull tab tape 90 with RFID tags 80 affixed can be combined with substrate 86, or can be supplied to a sealing manufacturer, a closure manufacturer, a lining manufacturer, the filling operation, and the like, for incorporation in a closure set.
    [0062] RFID 80 tags, evenly spaced, can be incorporated into the pull tab tape 90 before, or generally simultaneously, by attaching the pull tab tape 90 to substrate 86. RFID 80 tags can be attached to the top or bottom side of the pull tab tape 90 to form a hinged pull tab 82 having an RFID tag 80, as shown in figure 11. Alternatively, RFID tags 80 can be incorporated on the top side of substrate 86.
    [0063] In a seventh example embodiment, illustrated in figure 12, the pull tab tape 90 may comprise a double layer which includes a top liner 94 and a separate bottom liner 96 affixed to substrate 86 to form a hinged pull tab 98. The upper lining 94 and the lower lining 96 can be rotated separately around the hinge line 50.
    [0064] During the manufacturing process, the upper and lower liners 94, 96 can be separated to allow the RFID tags 80 to be inserted between them, corresponding to the selected location of the RFID tags 80 on the finished pull tab 82. Subsequent sealing of the upper lining 94 to the lower lining 96 can enclose the RFID tags 80 within the pull tab tape 90.
    [0065] The pull tab 82 may alternatively include a combined hinge and frangible line to allow selective removal of the pull tab 82, and the built-in RFID tag 80 from the pull tab lining 76. Subsequently, lock sets individual 14 of a pre-selected configuration can be separated from stock material 84 by methods, such as punching, as shown in figure 13, laser cutting, and the like.
    [0066] Alternatively, the RFID tag 80 can be inserted between any two of the various layers comprising the closure assembly 14, such as between the pull tab lining 76 and the support lining 78, between the support lining 78 and the closing the inner surface of the end wall between a facing lining and the supporting lining 78, and the like.
    [0067] In an eighth example embodiment illustrated in figures 14 and 15, an RFID closure set 110 includes an RFID tag set 112 having an RFID tag 120 mounted on an RFID guide 114. The RFID guide 114 can be suspended from of a display liner, such as support liner 78, metal foil 24, or another suitable liner, such as a pull-tab attachment that extends downward to interior space 18. Figure 14 illustrates the assembly RFID closure 110 as including a closure 15, a support liner 78, an RFID tag assembly 112, and an internal seal 21 comprising a foil 24 and a sealable film 22.
    [0068] The example modality of figures 14 and 15 can be manufactured and used in the same general way as the modalities illustrated in the previously referenced figures. The guide 114 can have any appropriate configuration, such as semicircular, or the type of strip, suspended from the center of the display liner or from another selected location on the display liner. In this embodiment, a separate pull tab, generally in accordance with the pull tabs previously described, can be incorporated, or not, in the closure assembly 110.
    [0069] The support liner 78 can be a material, as previously described here, suitable for repeatedly sealing a container opening 16 after the closure 15 has first been removed by an end user, and the contents of the container initially accessed. The support liner 78 may comprise a foam, or other resilient compressible material, suitable for sealing the container opening 16 after the closure 15 has been refitted. The support liner 78 can be frictionally or mechanically engaged with the upper part of the closure 15, which includes the use of an adhesive.
    [0070] The RFID tag set 112, for example, is illustrated in figures 14 and 15 as a slightly T-shaped guide 114 and an RFID tag 120. The RFID tag 120 may include a microprocessor and an antenna generally as previously described on here. Guide 114 may comprise a polymeric material having properties suitable for the purposes described herein, such as radio frequency transparency, strength, electrical insulation / insulation, and the like. Alternatively, the guide 114 can comprise an integrated metal foil, generally as previously described here, with a microprocessor, with appropriate isolation of the microprocessor from the guide 114, also generally as previously described here.
    [0071] As illustrated in figure 15, the guide 114 may comprise an elongated strip 116 accommodating a pair of intermediate fold lines and 130, 134, and a middle fold line 132, which extends transversely to the longitudinal axis of strip 116. Fold lines 130, 132, 134 allow strip 116 to be folded into the guide 114 shown in figure 14, and define a pair of center panels 122, 124 between the middle fold line 132 and intermediate fold lines 130, 134 , and a pair of outer panels 126, 128 between the intermediate fold lines 130, 134 and the ends of the RFID strip 116. The joined center panels 122, 124 can define an RFID shell 136 to retain the RFID tag 120. The center panels joined 122, 124 can also define a display flange 138 to affix the guide 114 from, as an example, the support liner 78.
    [0072] Prior to folding the RFID strip 116, the RFID tag 120 can be sandwiched between the two center panels 122, 124, which can be properly joined together, such as by an adhesive to form the RFID wrapper 136. The closure of the RFID tag 120 in RFID wrapper 136 can provide protection for RFID tag 120. RFID tag 120 can be electrically coupled to one or both of the center panels 122, 124 so that one or both of the center panels can serve as an antenna for radio frequency or high frequency.
    [0073] With the RFID strip 116 folded to the T-shaped configuration, an adhesive can be applied to the display flange 138 to affix the RFID tag set 112 to an appropriate surface, such as the support liner 78. The set of RFID tag 112 can be attached to support liner 78 before or after support liner 78 is joined with lock 15. With any process, metal foil 24 and sealable film 22 can be attached to lock 15, just like with liner support 78. Before adding foil 24 and seal film 22, the RFID wrapper 136 can be folded against the support liner 78, or the closed end of the closure 15, thereby sandwiching the RFID wrapper 136 between the liner support 78 or closure end and the metal sheet 24 when the closure 15 is tightened onto the container 12.
    [0074] Other configurations of an RFID tab can be used. For example, the strip may have a single fold line dividing the strip into a pair of panels (not shown) arranged in an L shape to define an attachment flange and an RFID tag holder. The display flange can be provided with an adhesive to affix the RFID guide to a support disc, and the RFID tag holder can support an RFID tag, and can be adapted as an antenna, as previously described here. The closure set described here allows the RFID tag to be incorporated into the closure set at a relatively early stage in the manufacturing process, which can improve efficiency and thus contribute to lowering cost and improving quality control.
    [0075] In a ninth example embodiment, illustrated in figure 16, the RFID tag 120 can be attached to the metallic foil 24 and / or sealable film 22, instead of the support liner 78, to extend to the container 12 when the RFID closure assembly 110 was affixed to the container opening 16. Alternatively, the RFID tag 120 can be inserted between the foil 24 and sealable film 22. In any configuration, the microprocessor 27 must be electrically isolated / isolated from the metallic sheet 24.
    [0076] Alternatively, an RFID tag can be incorporated into a support disc during the manufacture of the support disc. Support disks can be manufactured from stock material already supplied with RFID tags. RFID tags can be added to a stock material immediately before or after separating the support disks from the stock material. An RFID tag can be attached to a surface of a support disc, such as a surface engaging the closed end of a fastener, or embedded within a support disc, such as in a pouch formed on the support disc or between layers of a laminated support disc.
    [0077] In addition, an RFID tag can be added to a clasp, for example, affixed to the closed end of the clasp, after the clasp is manufactured, but before adding a support liner or internal seal. The RFID tag can thus be hidden by the support liner or internal seal. If the resealable container is to contain pharmaceutical products that can be eroded or fractured during handling, an RFID tag can be incorporated into the padding material that is inserted into the container and occupies the space between the product and the closure assembly.
    [0078] The closure assembly is advantageous in that it can be easily manufactured, with the RFID tag incorporated in the closure assembly during the production of the closure assembly, or at some other time and place. For example, the sealing of the container can be expected to occur after filling the container with a selected product. Thus, the closure and container assembly can be manufactured, stored, and transported separately until after the filling step.
    [0079] RFID tags can be incorporated into a closure assembly during any of the various process steps, such as during the manufacture of the closure assembly, or the filling and sealing of the container. Factors, such as the production of containers that can be closed with or without RFID tags, the information to be stored and transmitted by an RFID tag, the stage at which information is available for storage on an RFID tag, the preferred configuration of a RFID tag when incorporated into a closure and container assembly, and the like, can create a need for flexibility in incorporating an RFID tag into a resealable container. The manufacture, encoding, and incorporation of an RFID tag can be controlled by an entity other than the manufacturer of the closure assembly, such as a product manufacturer or a container filler, and at an optimal step in the process, just as at the time when that the container is full.
    [0080] Figure 17 illustrates an example manufacturing, filling, and sealing process for a container having an RFID closure assembly. In this process, closures are prepared in step 144, support is prepared in step 146, and a seal assembly is prepared in step 148. Steps 144, 146, 148 can proceed in parallel. The closure and support can be installed in a joining step 150. If no RFID tag is to be used, the closing and closing assembly can be installed in a joining step 152, followed by or during a container filling step 154, and followed by assembly of the filled container and closure assembly in a coupling step 156. If sealing or induction sealing is to be used, this can occur in a sealing step 160.
    [0081] If an RFID tag is to be used, after the joining step 150, the RFID tag can be joined to the holder in an RFID joining step 158. This can be followed by the joining step 152, the filling step 154 , and the closing joint step 156. The process is completed by the sealing step 160. A closing manufacturer can implement steps 144, 146, 148, 150, and 152. Step 158 can also be implemented by a closing manufacturer close. Otherwise, the RFID tag can be added by an RFID supplier, or by a product manufacturer, product filler, or product distributor.
    [0082] The addition of an RFID tag to a closure set can occur in an alternate sequence of steps appropriate for a selected process of manufacturing a product, manufacturing closure sets and containers, filling containers with a product, and distribution filled containers. For example, an RFID tag can be added to the holder during the preparation of the holder, before joining the holder with the lock.
    [0083] Figure 18 illustrates another example manufacturing, filling, and sealing process for a container having an RFID closure assembly. The process illustrated in figure 18 is similar to that illustrated in figure 17. However, prior to joining the lock and support in step 150, the RFID tag is affixed to the support disc in an RFID display in step 158. This is followed by joining the closure assembly and support disk in a joining step 150, and joining the closure assembly and closure assembly in a joining step 152. The process can culminate in a container filling step 154, a joining step closure 156, and a sealing step 160.
    [0084] Figure 19 illustrates yet another example embodiment of an RFID closure set according to the invention. The embodiment of figure 19 includes a container 12, the closure 15, a support liner 78, an embedded part that includes a microprocessor 27 electrically coupled with an antenna 52, and a pair of metal sheets 24, each generally as previously described here . The metal sheets 24 can be sealed together along a lower glue line 70 and an upper glue line 72, leaving a central pocket. The embedded part can be inserted between the metal sheets 24 before sealing, so that the embedded part is retained within the central pocket. Based on factors such as the size and configuration of the antenna, the frequency at which the embedded part operates, for example, LF, HF and UHF, characteristics of the transmitter / reader, whether the embedded part is active or passive, and the like, electromagnetic interference from the contact of the embedded part with any metallic foil 24 can be minimized or eliminated.
    [0085] Alternatively, one or more electromagnetically neutral ceilings can be retained between the metallic sheets 24 to enclose the embedded part and isolate the embedded part from the metallic sheets 24. The metallic sheets 24 can also enclose the embedded part without being sealed together, allowing as soon as the embedded part "floats" between the metal sheets 24.
    [0086] In another alternative configuration, the metal sheets can be manufactured to be thicker than the metal sheets 24 previously described, even to the extent of being essentially inflexible. The metal sheets can be cast, instead of being drawn or laminated, and can be manufactured in such a way that the embedded part is incorporated during the casting process. The performance of the embedded part can, as described above, be optimized based on the size and configuration of the antenna, the frequency at which the embedded part operates, characteristics of the transmitter / reader, whether the embedded part is active or passive, sheet metal properties , and the like.
    [0087] Figure 20 illustrates another example embodiment of an RFID closure set according to the invention. In the embodiment of figure 20, the container assembly 10 is shown to be closed, with only the container 12 and closure 15 visible. A flush part including a microprocessor 27 and an antenna 52 is positioned on the end wall of the closure 15. The container assembly 10 includes an outer seal 100 that extends over at least a portion of the container assembly 10, such as the closure 15 and an upper part of the container 12. The outer seal 100 may include a suitable material, such as a shrinkable wrap. With this example embodiment, the embedded part can be joined to the closure 15, or the container 12 provided with it is overlaid by the outer seal 100. Alternatively, the embedded part can be incorporated into the outer seal 100 to be positioned in a selected location in relation to the container assembly 10. The outer seal 100 and the insert can be configured in such a way that when the outer seal 100 is removed, the insert can be removed together with it, and thus arranged, thus eliminating issues of potential privacy. An internal insert can also be incorporated into the closure assembly, as previously described here, so that if the outer seal 100 and insert are removed, the internal insert will remain with the container assembly 10.
    [0088] An RFID tag can be incorporated into the container set 10 at a relatively premature stage, in a distribution process, and can increase production / manufacturing efficiencies, thus contributing to lower costs for the consumer and improving the quality control.
    [0089] Although the invention has been specifically described in connection with certain specific embodiments thereof, it should be understood that this is by way of illustration, not limitation. Reasonable variation and modification is possible within the scope of the preceding exhibition and the drawings without departing from the spirit of the invention which is defined in the appended claims.
