Claim 1
Independent Claim
149 words
A cushion bag comprising: an exterior layer, a cushion interior layer joined to and in contact with said exterior layer, said interior layer and exterior layer including a central portion and first and second outer sections, said first and second outer sections having a width less than said central portion, said first outer section being wider than said second outer section and having a marginal section, said marginal section being narrower than said second outer section, crease lines extending longitudinally between said central portion and said outer sections, said marginal section overlapping said second outer section and said interior and exterior layers forming a closed end portion and an open end portion, said interior layer of said closed end portion being compressed, said closed end portion having a return fold, and said open end portion having a compressed interior layer whereby a relatively thin closure tab may be formed.
