The present invention provides a panel which may be removably inserted into a nonrigid container, which container is comprised of at least one container wall defining a container opening. The panel is characterized at least in that it is formed from a flexible material having a memory of its original shape such that it can be coiled and returned to its original shape upon release. Preferably, the device is rectangular and includes a series of memory retention units therein. Among the advantages provided by the device is that it may be repeatedly coiled and inserted into a nonrigid container so that, upon release, the container may be retained in an upright and open position for easy access, all without breaking or cracking and without damaging the container either during retention of the container or during its removal therefrom.
