Abstract:
A closure system on a pliable container for use in repetitively opening and sealingly closing an openable end of the pliable container comprising: first and second shape memory elements each of which assumes a bowed shape in a relaxed state so as to define an elongated, generally concave surface portion and an opposing, generally convex surface portion, the first and second shape memory elements being attached to respective opposing side walls of the pliable container adjacent the openable end and interconnected solely through the pliable container, with the generally concave surface portions of the first and second shaped memory elements facing each other when the pliable container is in an open condition to maintain the opposing side walls in a spaced relationship to permit ready access to an interior of the pliable container and with the generally concave surface portion of the first shape memory element nesting with the generally convex surface portion of the second shape memory element when the pliable container is in a closed condition to maintain the side walls in a close bearing relationship at the openable end.
