A closure system for use in repetitively opening and sealing closing an openable end of a pliable container includes at least one bowed band which is connected to the container, as well as at least one closure member. In certain preferred embodiments, bands are connected to opposing side walls of the container, with the bands being interconnected by the closure member. When the container assumes an open condition, the bands are generally located in offset planes and, when the container is in a closed condition, the bands nest with at least one side wall portion of the container being located between the bands. The closure member has spring characteristics which tend to bias the bands together when the closed condition is selected, yet permits the container to be readily maintained in the open condition when desired. In other preferred embodiments, a closure member which tends to coil up is utilized to establish the closed condition.

[ I claim:] [1.] In a pliable container including at least first and second opposing side walls and an openable end defined, at least in part, by upper terminal edges of the side walls, a closure system for repetitively opening and sealingly closing the openable end of the pliable container comprising:a first band extending transversely across and being attached to the first side wall adjacent the openable end at a first level;a second band extending transversely across and being attached to the first side wall at a position spaced from the first band, said second band being arranged above the first level when the closure system assumes an open condition, wherein an interior of the pliable container can be accessed through the openable end, and nests with the first band substantially in the first level when the closure system assumes a closed condition, wherein the openable end of the pliable container is sealingly closed; anda spring member coupled to each of the first and second bands, with said spring member creating a biasing force acting between the first and second bands to at least retain the first and second bands nested when the closure system is in the closed condition.
