Definitions

  • This disclosure generally relates to closure arrangements for packages.
  • this disclosure relates to closure arrangements having a tamper-evident structure and reclosable profiles.
  • Resealable packages are convenient in that they can be closed and resealed after the initial opening to preserve the enclosed contents. The need to locate a storage container for the unused portion of the products in the package is thus avoided. As such, providing products in resealable packages appreciably enhances the marketability of those products.
  • Some perishable goods are sold to consumers in the form of a reclosable package.
  • cheese or meat products can be packaged in a bag with reclosable closure profiles such that after opening the package, it can be reclosed. It is desirable that these packages be hermetically sealed to prevent spoilage. It is also desirable that these packages include tamper-evident structures to inform the consumer whether the package previously has been opened.
  • a reclosable package includes a closure arrangement having a zipper, a slider device, and a tamper-evident structure positioned above the zipper.
  • the zipper includes first and second closure profiles that are releasably engageable with each other.
  • the first and second closure profiles are interconnected with a fold area including the tamper-evident structure.
  • the slider device is mounted to the upper and slides relative to the zipper to control interlocking and disengaging between the closure profiles.
  • the fold area may be in a variety of configurations.
  • the fold area is configured as a C-channel.
  • the fold area is configured as an inverted V.
  • the fold area is configured as an M.
  • the fold area is configured as an inverted U.
  • the tamper-evident structure may have a variety of constructions.
  • the structure is an area of weakness.
  • the structure is a peel seal.
  • the structure is a solid fold.
  • FIG. 1 illustrates an example packaging arrangement in the form of a resealable, flexible package 10 having a closure arrangement 8.
  • the closure arrangement 8 includes a zipper 11 with first and second closure profiles 12, 14; a slider device 16 to open and close the profiles 12, 14; and a tamper-evident structure 18 located above the zipper 11.
  • the tamper-evident structure 18 signals to the consumer whether the package has been opened previously.
  • One advantage of having the tamper-evident structure 18 located above, instead of below, the zipper 11 is that the consumer is able to identify whether the package 10 previously has been opened prior to opening the zipper 11.
  • the flexible package 10 includes first and second opposed panel sections 20, 22 made from a flexible, polymeric film.
  • the first and second panel sections 20, 22 are heat sealed together along two edges 24, 26 and meet at a fold line in order to form a three-edged containment section for a product within the interior of the package 10.
  • the fold line comprises the bottom edge 28.
  • two separate panel sections 20, 22 of polymeric film may be used and heat sealed together along the two edges 24, 26 and at the bottom 28. Access is provided to the interior of the package 10 through a mouth 30.
  • the zipper 11 can include a variety of configurations and structures.
  • the zipper 11 can be constructed according to U.S. Patent Nos. 4,240,241; 4,246,288; or 4,437,293; each of which is incorporated by reference herein.
  • the slider device 16 can include a variety of configurations and structures.
  • One particular example of a suitable slider device 16 is illustrated in more detail in FIGS. 2-5.
  • the slider device 16 includes a top wall 50 and a pair of side walls 52, 54 extending from the wall 50 such that the walls 52, 54 form a generally C-shaped channel.
  • the slider device 16 also includes a spreader or plow 56 extending or projecting from the wall 50.
  • the plow 56 comprises first and second angled wedges 58, 60 separated by a gap 62.
  • FIG. 5 illustrates a cross-section taken along the line 5-5 of FIG. 4.
  • First and second hook constructions 70, 72 are viewable in FIG. 5.
  • First and second hook constructions 70, 72 help to permit the slider device 16 to slide along the zipper 11 without becoming disengaged from the package 10.
  • FIG. 6 illustrates a cross-sectional view of the closure arrangement 8 taken along the 6-6 line of FIG. 1.
  • FIG. 6 generally shows package 10 including first and second opposed panel sections 20, 22, zipper 11, tamper-evident structure 18, and slider device 16.
  • the zipper 11 has first and second closure profiles 12, 14.
  • the first and second closure profiles 12, 14 are releasably engageable with each other to provide a reclosable seal to the package.
  • the first and second closure profiles 12, 14 are connected through a fold area 100 having tamper-evident structure 18.
  • the first closure profile 12 has a first depending fin or flange 102 extending therefrom, while the second closure profile 14 has a second depending fin or flange 104 extending therefrom.
  • the zipper 11 is formed separately from the panel sections 20, 22, the first and second fins 36, 40 are thermally fused to inner surfaces of the respective first and second panel sections 20, 22.
  • the zipper 11 may be extruded with the panel sections 20, 22 such that the first fin 36 is integrally formed with the first panel section 20, and the second fin 40 is integrally formed with the second panel section 22.
  • FIG. 7 illustrates the zipper 11 depicted in FIG. 6 in an unfolded configuration.
  • the zipper 11 has first and second closure profiles 12, 14 respectively including first and second posts 120, 122 and first and second closure members with a hook 124, 126.
  • the first and second closure profiles 12, 14 are interconnected with the fold area 100 which extends from the first closure member with a hook 124 to the second post 122.
  • the fold area 100 has a fold point 128 suitable for providing a tamper-evident structure 18. In this embodiment, the fold point 128 is the midpoint 130 of the fold area 100.
  • the fold point 128 need not be the midpoint 130 of the fold area 100 but may be located, for example, to the right or left of the midpoint 130 of the fold area 100, between the first closure member with a hook 124 and the midpoint 130 of the fold area 100, or between the second post 122 and the midpoint 130 of the fold area 100.
  • the tamper-evident structure 18 located within the fold area 100 can be a variety of constructions.
  • the tamper-evident structure 18 may be a peel seal, an area of weakness, or a solid fold or web that requires cutting to open.
  • peel seal it is meant that the bonding strength between the layers forming the peel seal is less than the bonding strength of other layers in the package 10, so that when a pulling force is applied, the layers forming the peel seal will break or peel apart before other portions of package 10. Peel seals are known in the packaging art, and examples of peel seals that may be useable with the package of the present disclosure are taught in U.S. Patent Nos. 4,923,309; 4,925,316; 5,425,825; 5,456,928; 5,470,156; and 5,733,636, the disclosures of which are incorporated herein by reference.
  • FIG. 8 illustrates a top view of the zipper in the unfolded configuration depicted in FIG. 7.
  • the fold area 100 has a tamper-evident structure 18 constructed from an area of weakness 132 created by a perforated line 134 along the fold point 128.
  • an area of weakness is created by, for example, a scored or thinned line.
  • a scored line is created by making a uniform crease approximately along the fold point 128 of the fold area 100.
  • a thinned line is created by coextruding the fold area 100 with less material approximately along the fold point 128 of the fold area 100.
  • the area of weakness is created by forming the fold area 100 out of a highly oriented material that has a tendency to split approximately along the fold point 128 of the fold area 100.
  • FIG. 9 illustrates a top view of another embodiment of an unfolded zipper analogous to the view depicted in FIG. 8.
  • the embodiment shown in FIG. 9 also has a fold area 140, a fold point 142, and a tamper-evident structure 144.
