The present invention provides a collapsible, foldable, stackable, and self-restorable container comprising semi-enclosed container body having two opposed side walls, two opposed end walls between the side walls, and a bottom panel enclosing one end of the container body. Each of the side walls includes a gusset extending in a direction substantially parallel to the bottom panel. The container further includes a lid attached to the container body for selectively converting the semi-enclosed container to a closed container. Finally, the container includes a closure means for sealing the lid to the container body. In accordance with the present invention the side walls and end walls are inwardly foldable toward one another, such that the container is collapsible in a direction normal to the lid and bottom panel while being substantially self-supporting while the side walls and end walls are in their unfolded orientation. The present invention also provides a storage container having 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. Accordingly, the storage containers of the present invention combine the desirable qualities of both flexible bags and storage containers and minimize the less desirable qualities of both approaches by providing improved sealability, being self-supporting in an open condition for filling, storing easily by folding into a compact form, and being unitarily constructed from inexpensive materials to promote disposability and obviate the need for separate closure devices. |
