Abstract:
1. A collapsed bag of unitary construction made of supple polymeric material subject to interlayer cling, comprising first and second opposed contiguous fiat sidewalls with joined lateral edges defining left and right sides of the bag; a bag mouth defined by upper edges of said sidewalls; said sidewalls being configured so that each has an exposed graspable sidewall portion, at least where proximate to said bag mouth, the exposed graspable sidewall portions of said respective opposed sidewalls being located on laterally opposite edges of said bag, said exposed graspable sidewall portions thereby being diagonally opposed, whereby a clinging tendency of the contiguous sidewalls to each other can be overcome by tensioning the exposed graspable portions against each other and laterally displacing relative to each other said sidewalls over substantially the full width between said exposed graspable portions to introduce a shearing action between said contiguous sidewalls; a pair of opposed side gussets located between said first and second opposed contiguous sidewalls, each said gusset having first and second gusset panels hingedly joined to respective side edges of said first and second sidewalls, said gusset panels being freely displaceable and deformable relative to said sidewalls; and said sidewalls being configured such that a said diagonally opposed pair of exposed graspable sidewall portions is provided proximate to said bag mouth, and wherein said graspable sidewall portions are exposed by weakenings, voids, truncations or openings formed in or adjacent to the lateral edge of said sidewalls and their associated gusset panels.
