Description
Dual Aluminum Tamper Indicating Tabbed Sealing Member
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims benefit of United States Provisional Application Number 61/936,218, filed February 5, 2014, which is hereby incorporated herein by reference in its entirety.
FIELD
[0002] The disclosure relates to sealing members for use as secondary closures on containers, and more particularly, to tamper indicating tabbed sealing members.
BACKGROUND
[0003] It is often desirable to seal the opening of a container using a removable or peelable seal, sealing member, or inner seal. Often a cap or other closure is then screwed or placed over the container opening capturing the sealing member therein, Tn use, a consumer typically removes the cap or other closure to gain access to the sealing member and then removes or otherwise peels the seal from the container in order to dispense or gain access to its contents.
[0004] In some cases, the inner seal provides tamper evidence whereby a portion of the seal remains on the container as evidence that the sealing member has been removed or tampered with. For instance, upon removal of the sealing member from the container, the laminate forming the sealing member is designed to rupture and leave debris on the container finish to indicate that the package has been opened. Prior examples of such tamper evidence tabbed liners resulted in a laminates that left debris on the container directly dependent on the placement of the tab. For example, if the tab wras on the top of the sealing member and defined wholly within its perimeter and covering approximately 50 percent of the seal, then prior seals generally left debris on the container land area and also covering over approximately 50 percent of the container opening. The consumer would then need to remove this remaining seal portion in order to effectively use the container, which tended to serve as a nuisance to some consumers and in some applications.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] FIG. 1 is an image of the tabbed sealing member of the disclosure shown removed from a container with residual material left on the container rim land area;
[0006] FIG. 2 is an exploded cross-section view of an exemplary tabbed sealing member of the disclos re; and
[0007] FIG. 3 is another exploded cross-sectional view of an exemplary tabbed sealing member of the disclosure.
DETAILED DESCRIPTION
[0008] The present disclosure generally relates to tabbed sealing members having a gripping tab defined wholly within a perimeter of the seal that is also configured to provide tamper evidence. The sealing members herein eliminate the excessive debris left by prior tamper evidence top-tabbed type inner seals. In one aspect, the sealing members herein are arranged and configured to isolate the residual debris, after removal of the sealing member from the container via the tab. to the land region of the container rim independent of the size or positioning of the tab on the top surface of the sealing member. In another aspect, the tabbed sealing members herein utilize a unique dual foil assembly or dual layered aluminum assembly to aid in achieving the isolated debris left as a ring of sealant and single aluminum layer on the container rim.
[0009] In a preferred approach, a dual layered aluminum sealant component or laminate is configured upon removal from the container to leave a residue of sealant and aluminum remnants isolated to the container finish, which controls the amount of residual liner remaining on the container after opening. Preferably, the isolated remnants are a thin annular ring of the sealant and aluminum layers. Reducing the land areas and also stepping in the container finish help to reduce the removal force of this design. That is, the top surface area of the container rim land area may be reduced. The separation functionality is controlled by the gauge of the aluminum in the base layer and the selection of the adhesive between the two layers.
[0010] By one approach, the tabbed sealing member includes the lamination of a base foil layer and sealant component that is bonded to a secondary foil component to form a tamper evidence substructure. The bonding may be by extrusion lamination or thermal lamination.
Optional layers may then be applied to the tamper evidence substructure, such as foam layers, non-foam polymer layers., and various tab components to form a tamper evidence sealing member configured to isolate the residual debris to the container rim. This laminate can be used as a single element liner system or within a two-piece assembly where the sealing member is temporarily bonded (such as by wax) to a pulp or synthetic backing material in a so-called two-piece seal and liner configuration,
[0011] For simplicity., this disclosure generally may refer to a container or bottle, but the sealing members herein may be applied to any type of container, bottle, package or other apparatus having a rim or mouth surrounding an access opening to an internal cavity. In this disclosure, reference to upper and lower surfaces and layers of the components of the sealing member refers to an orientation of the components as generally depicted in figures and wrhen the sealing member is in use with a container in an upright position and having an opening at the top of the container. Different approaches to the sealing member will first be generally described, and then more specifics of the various constructions and materials will be explained thereafter. It will be appreciated that the sealing members described herein, in some cases, function in both a one-piece or two-piece sealing member configuration. A one-piece sealing member generally includes just the sealing member bonded to a container rim. A cap or closure may be also used therewith. A two-piece sealing member includes the sealing member temporarily bonded to a liner. In this construction, the sealing member is bonded to a container's rim, and the liner is configured to separate from the sealing member during heating to be retained in a cap or other closure used on the container. In a two-piece construction, a wax layer, for example, may be used to temporarily bond the sealing member to a liner. Other types of releasable layers may also be used to provide a temporary bond between the seal and liner, but the releasable layers are generally heat activated.
[0012] Turning to FIG. 1, one example of a tamper evidence tabbed sealing member 10 is shown. Seal 10 Includes an upper laminate 12 partially bonded to a lower laminate 14 via a partial bond 16 to form a gripping tab 17 defined wholly within a perimeter of the seal. In this approach, the seal also includes a partial layer or tab stock 18 to aid in forming the tab 17. The tab stock 18 is bonded to layers in the upper laminate 12 but not bonded to layers in the lower laminate 14.
[0013] The upper laminate 12 may also include a polymer film support layer 20 to provide structural support and a co-polymer layer or bonding layer 22 to bond the polymer film 20 to the lower laminate 14. Here, the film 20 is partially bonded to the tab stock 8 and partially bonded to the lower laminate via the bonding layer 22.
[0014] Support film layer 20 may be may be polyethylene terephthaiate (PET), nylon, polyoiefin, or other structural polymer layer and may be, in some approaches, about 0.5 to about 2.5 mil thick.
[0015] When using the tab stock 18, the tab 17 is defined or formed via the tab stock 8 that extends only part way across the upper laminate 12. More specifically, the tab stock 18 forms the tab 17 because it bonds to the bonding layer 22 and generally prevents layer 20 (and any layers above) from adhering to the upper surface of the lower seal laminate 14 (or any layers therebetween) across at least a portion thereof. A bottom surface of tab stock 18 is adjacent to, but not bonded to, the upper surface of the lower laminate 14 to form the tab 17. In one aspect, the tab stock 18 is formed of polyester, such as polyethylene terephthaiate (PET), or paper. By one optional approach, a IowTer surface of the tab stock 18 may be coated with a release material, for example silicone. The optional release coating minimizes the possibility that the tab stock 18 will become adhered to the upper surface of the lower laminate 14 during the heat sealing or induction heat sealing process. The tab stock 18 permits the tab structure 17 to pivot or hinge upwardly along a boundary line to form the tab 17. By this approach, the Lab stock 18 and formed tab 17 are defined wholly within a circumference or perimeter of the seal.
[0016] The bonding layer 22 may include an polymer materials that adhesively bond, are heat activated, or heated to achieve its bonding characteristics or application to the seal. By one approach, the bonding layer 22 may be selected form ethylene vinyl acetate (EVA), polyoiefin, 2-component poiyurethane, ethylene acrylic acid copolymers, curable two-part urethane adhesives, epoxy adhesives, ethylene methacry!ate copolymers and the like bonding materials. As shown, the heat activated bonding layer 22 extends the full width of the laminate segment 12. In other approaches, the laminate 12 may only include a partial layer of adhesive and, thus, not use the tab stock layer 18 discussed above.
[0017] By one approach, the bonding layer 22 is EVA with a vinyl acetate content of about 20 to about 28 percent with the remaining monomer being ethylene in order to achieve
the bond strengths to securely hold the upper laminate to the lower laminate. In some cases, a vinyl acetate content lower than 20 percent is insufficient to form the robust structures described herein. By one approach, bonding layer 22 may be about 0.5 to about 3.5 mil of EVA, in other approaches about 0.5 to about 2.5 mils of EVA, in other approaches, about 0.5 to about 1.5 mils of EVA and, in yet other approaches, about 0.5 to about 1.0 mils of EVA; however, the thickness can vary as needed for a particular application to achieve the desired bonds and internal strength.
[0018] The lower laminate 14 forms the tamper evidence substructure of the unique tamper evident sealing member 10. This substructure includes a lower sealant or heat seal layer 30 that may be composed of any material suitable for bonding to the rim of a container, such as but not limited to induction, conduction, or direct bonding methods. Suitable adhesives, hot melt adhesives, or sealants for the heat sealable layer 30 include, but are not limited to, polyesters, polyolefins, ethylene vinyl acetate, ethylene-acrylic acid copolymers, surlyn, ionomers and other suitable materials. By one approach, the heat sealable layer may be a single layer or a multi-layer structure of such materials about 0.2 to about 3 mils thick. By some approaches, the heat seal layer is selected to have a composition similar to and/ or include the same polymer type as the composition of the container. For instance, if the container includes polyethylene, then the heat seal layer would also contain polyethylene. If the container includes
polypropylene, then the heat seal layer would also contain polypropylene. Other similar materials combinations are also possible. By one approach, the seal layer 30 is about 1 to about 2 mils thick or, in some approaches, about 1.5 mil thick medium density polyethylene film (In some cases about 0.92 to about 0.94 g/cm, but may be other density as needed).
[0019] Next, the lower laminate includes a first, base, or primary membrane layer 32. The base membrane layer 32 may be one or more layers configured to provide induction heating and/or barrier characteristics to the seal 10. A layer configured to provide induction heating is any layer capable of generating heat upon being exposed to an induction current where eddy currents in the layer generate heat. By one approach, the membrane layer may be a metal layer, such as, aluminum foil, tin, and the like. In other approaches, the membrane layer may be a polymer layer in combination with an induction heating layer. The membrane layer may also be or include an atmospheric barrier lay er capable of retarding the migration of gases and moisture at least from outside to inside a sealed container and, in some cases, also provide
induction heating at the same time. Thus, the membrane layer may be one or more layers configured to provide such functionalities. By one approach, the membrane layer is about 0.3 to about 2 mils of a metal foil, such as aluminum foil, which is capable of providing induction heating and to function as an atmospheric barrier. In one particular approach, the member layer 32 is a 1 mil thick aluminum foil. There is some advantage in reducing the gauge of the aluminum component in the base foil laminate or substructure. Thinner aluminum foil is easier to break and the use of thinner foil reduces the force required by the consumer to peel the liner form the container. In some approaches, the foil layer 32 is thinner than the lower heat seal layer. The combination of the seal layer 30 and base foil layer 32 forms a substructure composite laminate 34.
[0020] Next, the sealing member includes a bonding layer 36 (or hot melt adhesive) above the base foil layer 32. The correct separation of the sealing member to isolate the residue to the container land area is generally dependent on the selection of this bonding layer 36. Thickness of this layer also helps achieve the unique functionality of the seals herein. The hot melt layer may have a thickness from about 1 to about 3 mils. Layer 36 needs to maintain lamination integrity to hold the seal component together, but also remain soft enough to peel away from the foil 32 above the container land area during seal removal by a consumer. Suitable examples of materials for the bonding layer 36 include co-extruded polyethylene/ EVA sealants having a high vinyl acetate composition (such as about 20 to about 40 percent). Other suitable materials for the bonding layer 36 may include EVA hot melts, EAA coatings, or PET heat seal films. In one particular form, the bonding layer 36 is EVA-based hot melt.
[0021] Above the bonding layer 36 there is a secondary foil component 38 and an upper polymer support component 40. The secondary foil component 38 may be similar to the base or primary foil (that is about 0.3 to about 2 mils thick), but in some approaches, may be equal to or thinner than the base foil component 32. The upper polymer support component 40 may be films,, foams, or other support materials. For instance, component 40 may be a polymer foam or a non-foamed polymer film, such as polyolefin, or polyester films or foams.
[0022] {..aver 40 may be an insulation layer or a heat-redistribution layer. In one form, layer 106 may be a foamed polymer layer. Suitable foamed polymers include foamed polyolefin, foamed polypropylene, foamed polyethylene, and polyester foams. In some forms,
these foams generally have an internal rupture strength of about 2000 to about 3500 g/in. In some approaches, the foamed polymer layer 106 may also have a density less than 0.6 g/cc and, in some cases, about 0.4 to less than about 0.6 g/cc. In other approaches, the density may be from about 0.4 g/cc to about 0.9 g/cc. The foamed polymer layer may be about 1 to about 5 mils thick.
[0023] In some approaches, a ratio of the base foil to the secondary foil may be about 1 :1 to about 5:1. In other approaches, the break-in or rupture force of the seal layers that remain on the container is proportional to the sealant areas available on the container land region of the container.
[0024] FIG. 2 shows an alternative embodiment of the tabbed sealing members herein. Various layers in FIG. 2 are similar to FIG. 1 and will not be described further. Some of the layers in FIG. 2 may be different in thickness such as a lower foil layer that is 0.5 mils or less, but can be the same as that described above,
[0025] FIG, 2 also shows the where the laminate ruptures upon sealing member removal to isolate the residue on the container land area. The laminate separates at 50 where the bonding layer 36 peels away from the base foil layer 32 above the container rim land area (Generally shown as 51). Then, the base foil 32 and lower sealant 30 rupture internally 54 along the inner edges of the container rim all around the rim. This separation isolates the sealing member residue 60 as a ring of material on the container rim as best shown in the image of FIG. 3.
[0026] In some approaches, there is a small overhang or annular flange of the sealing member extending beyond the container rim when sealed to the container rim. In some approaches, this overhang may be about 1 to about 3 mm. In other approaches, the container finish may be stepped inwardly so that the upper land area is reduced forming the overhang of material. This overhang of material is generally illustrated in FIG. 3.
[0027] n some approaches, the following features define the sealing members herein. The various features and limitations of the sealing members described above, in the figures, and discussed below are not exclusive to the mentioned sealing member, but may be included in any combination thereof. Mention of an aspect or embodiment of the seals or container herein is not intended to imply that such aspect or embodiment is mutually exclusive of all other aspects or embodiments. In other words, the various features as set forth herein may be united in various combinations as needed for a particular application and features in one paragraph may be combined with features in other paragraphs as needed.
