Abstract
The invention provides a bag container and method for making same with an improved removable section for conveying marketing and promotional messages. The section may be separated from the bag container without compromising the container's integral barrier wall, and provides an improved construction capable of use in high speed, high efficiency, automated handling systems. In addition, the invention provides the option of a bag container and a wrap with a highly secure, tamper resistant, removable section made from a one-piece blank, without the need for additional multi-part security systems or other added security systems.
Claims13
A container of a flexible, foldable barrier material comprising:
- a predimensioned outer wall with first peripheral borders in folded relation along fold lines defining and forming a closed end of the container and second peripheral borders defining an opening to the interior of the container, the second peripheral borders reversibly foldable from a first open position providing access to the interior of the container to a second closed position;
- at least one multi-ply panel integral to the outer wall formed of at least one inner ply and at least one outer ply disposed to cover the inner ply;
- the panel having a width and at least two opposing borders, the panel extending generally from the first peripheral borders of the outer wall to the second peripheral borders of the outer wall;
- the inner ply and outer ply substantially inseparable fixed together in at least two generally parallel, spaced zones defining the borders of the panel, the inner ply and the outer ply in a generally separable relation between the panel borders;
- and
- the outer ply provided with a gripping surface and at least two spaced frangible lines disposed between the panel borders and at least one frangible zone disposed along the outer ply and extending between the panel borders, the frangible zone spaced from the fold lines of the closed end of the container effective to permit the removal of the outer ply from the panel without opening the closed end of the container to expose the panel inner ply when the panel gripping surface is gasped and the outer ply is pulled away from the panel, and the frangible lines and frangible zone effective to resist disruption of the panel construction during handling and operation of the container.
A method for forming a container of flexible, foldable barrier material comprising the following steps:
- providing a predimensioned blank of the flexible barrier material;
- folding the blank into a container with an outer wall with first peripheral borders in folded relation along fold lines defining and forming a closed first end of the container and folding the blank into foldable peripheral borders of the blank defining an opening to the interior of the container in a first open position and substantially closing the container in a second, folded position;
- folding the blank into at least one multi-ply panel on the container outer wall with an inner ply integral to the outer wall and at least one outer ply disposed in a generally separable relation with the inner ply covering the inner ply, the panel having a width and at least two opposing borders, and the panel extending from the first peripheral borders to the second peripheral borders;
- providing the inner and out plies with at least two, generally parallel, spaced substantially inseparable zones defining borders of the panel and generally extending the length of the inseparable zones;
- and a frangible zone spaced from the fold lines of the closed end of the container.
- providing a gripping surface on the outer ply and at least two frangible zones between the panel borders effective to resist separation of the outer ply from the panel during handling and use of the container and to reduce the outer ply's resistance to separation from the panel when the gripping surface is gasped and the outer ply is pulled away from the panel to expose the panel inner ply;
- and providing at least one frangible zone spaced from the fold lines of the closed end of the container effective to permit the removal of the outer ply from the panel without opening the closed end of the container.
