Definitions

  • Hie present application relates generally to resealabfe packages.
  • the present application relates to reseaiable packages that provide for relatively easy access to the contents contained within the package while allowing users to reseal the package to store the contents for later use without the use of zippers or other mechanical fastening structures or components.
  • Conventional reseaiable packages for storing items such as frozen foods or other items may incorporate mechanical fastening structures or mechanisms to allow tor resealing of toe bag.
  • a zipper mechanism e.g., press-to-dose zippers, sliding zippers, etc.
  • These zippers can indude members (e.g., a male portion and a female portion, etc.) that are caused to selectively mate along toe length of the zipper to close and seal the bag.
  • Other packages may utilize different types of mechanical fastening structures such as snaps, buttons, dasps, or other similar dosure mechanisms.
  • toe fastening structures may become advocated during use of toe package when partides or fragments (e.g., crumbs, seeds, ice, frost, juice, etc.) of the products may become lodged within components of the fastening mechanisms, such as within toe female portion of a zipper mechanism. This in turn may make use of toe fastening mechanisms more cumbersome, and in some cases may prevent complete resealing of the package.
  • fastening mechanisms Even if a zipper or other fastening mechanism is not foiled, the fastening mechanisms may unintentionally decouple during movement of the package, resulting in contents spilling out of the package. Furthermore, the fastening mechanism used by current packages may be difficult for a user to locate or be aware of due to the position thereof inside the package. As a result, the user may inadvertently cut or damage the fastening mechanisms when initially opening the package, thereby negatively impacting the functionality of the fastening mechanism.
  • zippers and other mechanical fastening mechanisms are relatively thick* compared to die surrounding packaging material, and limit a number of packages that can be produced from a roll of film used to make such packages.
  • die product manufacturers may be required to frequently change between roils of packaging material, thereby decreasing production efficiency.
  • Certain types of fastening mechanisms are also relatively costly and may require specialized machinery to apply them to die packaging material, which increases the cost associated with the packaging for die products.
  • a resealable package includes a first edge and a fin seal.
  • the first edge defines a boundary between two panels.

  • the finger hold may be positioned in the center of the fin seal or lap seal. Hie user may then unfold file top of the package and remove the desired products from within the package.
  • the adhesive is less prone to fouling than zippers employed by current bags because the adhesive is positioned along an external surface of the resea!able package. Fragments of products are less likely to come into contact with the adhesive than the zippers of current bags which are in consistent contact with products due to the position of file zippers along inner surfaces of the bags, in contrast to the zippers of current bags, fire location of the fin seal or lap seal allows a user to easily locate the adhesive for use in resealing the resealable package.

Abstract

L'invention concerne un emballage réutilisable qui comprend un premier bord et un joint d'ailette. Le premier bord définit une limite entre deux panneaux. Le premier bord peut être retiré pour séparer les deux panneaux pour accéder au contenu à l'intérieur de l'emballage. Le joint d'ailette s'étend à travers l'un des deux panneaux dans une direction parallèle au premier bord. Le joint d'ailette comprend une région adhésive et un film qui comprend une partie amovible située sur au moins une partie de la région adhésive. Le joint d'ailette est configuré pour permettre la refermeture du sac par couplage de la région adhésive à l'un des deux panneaux.
