The present invention provides aflexible storage bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container. The bag has an opening and a closure means for sealing the opening to convert the semi-enclosed container to a closed container. The closure means comprises a strip of material forming at least a portion of the periphery of the opening having a first side facing inwardly toward the opening and a second side facing outwardly of the opening. The first side exhibits an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. In a preferred embodiment, the flexible storage bag includes at least one auxiliary venting opening located remotely from the primary opening and having an auxiliary closure means for sealing the auxiliary opening. The auxiliary opening has a periphery, and the auxiliary closure means comprises a piece of material forming at least a portion of the periphery and having a first side facing inwardly toward the opening and a second side facing outwardly of the opening. The first side exhibits an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. In another preferred embodiment, the flexible storage bag is self-supporting with the opening extending upwardly away from a horizontal supporting surface. The flexible storage bag may further include at least one pair of opposed gussets formed in the sheet material extending in a direction normal to the opening and a substantially planar bottom extending in a direction substantially parallel to the opening, such that when the bottom is placed on a horizontal surface the flexible storage bag is self-supporting and maintains the opening in an upwardly-extending condition. Preferably, the bag maintains the opening in a substantially open condition.

[ What is claimed is:] [1.] A flexible storage bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening and a closure means for sealing said opening to convert said semi-enclosed container to a closed container, said opening having a periphery, wherein said closure means comprises a piece of material forming substantially all of said periphery, said piece of material having a first side facing inwardly toward said opening and a second side facing outwardly of said opening, said first side exhibiting an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user, such that said first side is adherable to any opposing surface, said closure being a selectively activatable adhesive structure and comprising a three-dimensional, deformable material comprising an adhesive protected from external contact by the three-dimensional surface topography, and which is convertible to a substantially two-dimensional sheet material upon activation by a user to expose an adhesive layer to contact with an opposing surface of said semi-enclosed container across said opening.
