A flexible bag-like container comprises front and rear flat, rectangular, equal size panels of flexible sheet material which are sealed to each other entirely around their outer periphery. The front panel is made stiff and resiliently bendable about an axis in a region near one end and the rear panel has a slit extending along a line transverse to the bending axis. The slit terminates short of the sides of said container.

1. A flexible self closing container comprising two flat, rectangular, equal size panels of flexible sheet material sealed to each other around their outer periphery, one of said panels being made stiff and resiliently bendable about an axis at least in a region near one end thereof and the other panel having a slit extending along a line transverse to said axis and located within said region, said slit terminating short of the sides of said container,said one panel being stiffer and more resiliently bendable in said region than said other panel such that when the side edges of the container are squeezed together near said one end, the one panel is bent in a concave direction facing the other panel and causes a portion of the other panel on one side of the slit to flex outwardly, thereby to cause the slit to form an opening into the container, and when the sides of the container are released, the resilient panel reverts to a flattened condition to bring the region of the one panel on said one side of said slit back against the resiliently bendable panel, thereby to close said slit, the stiffened, resiliently bendable panel tending to hold the container flat in order to return the panel having the slit to a flattened condition in which the slit is held closed after it has been opened to insert or remove items into or out of said container.
