Abstract:
A flexible storage bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having two opposing side panels, two opposing gusseted end panels between said side panels, an opening defined by a hinged peripheral flange, and a substantially planar bottom opposite of and substantially parallel to said opening, said end panels each including a gusset extending in a direction normal to said opening, said hinged flange including a closure, said closure being selectively activatable without removal of a liner material for sealing said opening to convert said semi-enclosed container to a closed container, said closure comprising a three-dimensional sheet material having a plurality of protrusions separated by valleys, said three-dimensional sheet material being convertible to a substantially two-dimensional sheet material upon collapse of said protrusions in response to an externally applied compressive force exerted by a user to expose an adhesive layer to contact a complementary surface, wherein said side panels, said end panels, said bottom, and said hinged flange form a structure which enables said container to be self-supporting and maintains said opening in an upwardly-extending condition when said bottom is placed on a horizontal surface.
