Abstract
A lockable closure for a container having a foldable annular wall advantageously has locking means whereby the closure can be releasably locked to the container. The closure has an annular bendable wall adapted to be disposed at least partially in contact with the annular wall of the container. The bendable wall has a reversely bent annular lip adapted to be disposed about the outer edge of the annular wall of the container. Upon the closure being disposed with its reversely bent annular lip disposed about the outer edge of the wall of the container, the bendable wall of the closure and its annular lip are deflectable with the foldable wall of the container to fold the bendable wall into and out of locking engagement with the foldable wall of the container. The closure is retained in either the locked or unlocked positions without additional forces or apparatus as it is substantially in a zero stress condition at these positions.
