Abstract:
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; andthe 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.
