Abstract: A flexible, preferably transparent, container for food or other contents has a pliable body of flexible plastic material, the body having an opening with a closure flap extending from one side of the opening. The flap forms a continuation of the body and is pivotal relative to the body to close and open the opening. A stiffened portion is disposed around a peripheral portion of the opening opposite the one side, and another stiffened portion is disposed around a periphery of the flap. These stiffened portions are hingedly connected at opposite ends of the one side. The flap stiffened portion moves inside the opening stiffened portion when the flap closes the opening. The pliable body is collapsible to a collapsed disposition for storage when empty, and is variably adapted in size between the collapsed disposition and an expanded maximum size disposition depending upon the volume of contents to be stored in the container.
