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.
