Definitions

  • the present disclosure relates to packages and methods of making packages, and more particularly, to sealed reclosable packages and a method of making the same.
  • the field of disposable absorbent articles includes a wide variety of consumer products, including diapers, bibs, wipes, sanitary napkins, tampons, etc.
  • the absorbent articles are packaged in a primary package, such as a polybag.
  • a plurality of primary packages containing absorbent articles may be packaged in a secondary package, such as a cardboard box.
  • Primary packages for containing absorbent articles may include opposing first and second panels. Each panel may define a top edge portion, a bottom edge portion, a left side edge portion, and a right side edge portion. The first and second panels may be joined at a first seam along left side edge portions of the first and second panels and at a second seam along right side edge portions of the first and second panels.
  • the primary package may include a reclosable feature along a top or bottom edge portion of the package for opening and closing the packages.
  • the reclosable features may include a lid, tape tab fastener, hook and loop fastener, snap, button, or latch, for example.
  • adding reclosable features to the primary package may add cost and complexity to the manufacturing of the package.
  • Some primary packages include an integrated reclosable feature, such as a hood, in the second panel of the primary package.
  • the hood may be positioned proximate to the top or bottom edge portion of the primary package.
  • the hood may be configured in a closed configuration and an open configuration. In the closed configuration, the hood may cover the absorbent articles contained therein. In the open configuration, the hood may be folded away from the first panel to create an opening in the package that exposes the absorbent articles contained therein.
  • the first and second panels may be integrally connected in the portion of the panels opposite the hood. As such, the hood may provide the only access to the primary package for inserting absorbent articles during the packaging process, and for removing the absorbent articles from the primary package at the time of use by the consumer.
  • the package may not be sealed at the time of purchasing the primary package of absorbent articles because of the opening created by the hood. Consequently, the absorbent articles may be subject to tampering or contamination before the package of absorbent articles is purchased by the consumer.
  • reclosable primary package that is sealed at the time of purchase. Moreover, it would be beneficial to provide a primary package that is reclosable without the need for additional reclosable features. Additionally, it would be beneficial to provide a sealed reclosable package that is able to be filled with absorbent articles using automated packaging processes.

  • Exit structure is defined in the first material layer through which the composition exits the cavity in use of the packet.
  • a flap is defined by a portion of the opposed layers and is folded at a first fold line so as to extend over and releasably seal to the first material layer over the exit structure. To open the packet, the flap or an extension of the flap is pulled by the user causing the flap to peel away from the first material layer and unseal from over the exit structure.

  • the cover section or gusset has upstanding edges that define a shallow trough at the top of the bag.
  • the bag further includes a handle formed as a U-shaped loop which includes across the cover section and is attached to the opposite inner sides of the upstanding edges of the trough.
  • DE 37 21 675 discloses a coiled bag or pouch made of thermoplastic film material, such as is used for packaging, for example, tobacco, has a bag which is folded in an essentially U-shape, possibly forming a folded-in bottom fold, from a piece of film and is welded at the side edges.
  • the bag is provided, in the region of its opening, with a fold-over or coiling tab which extends its rear wall, that can be folded over the bag opening and, if appropriate, fixed to the bag by its part which covers the bag opening.
  • the arrangement is such that the front wall of the bag located opposite the fold-over or coiling tab has, in the region of the bag opening, an attached covering tab which can be welded to the inner side of the rear wall or of the fold-over or coiling tab whilst sealing the bag opening, the covering tab being bounded, on the side facing the bag, by a transversely running intended tearing line over at least part of its length.
