Title: Refillable container for dispensing photosensitive rolled sheet

Abstract: A flexible plastic rectangular container for dispensing bulk rolled paper is molded with a stiffened top lid attached by an elastic hinge pre-stressed to hold the lid open. The stiffened lid has a skirt portion with latching projections to engage recesses in the container ends when the lid is closed. Manual application of a torsional couple to the container ends so distorts the container as to release the projections from the recesses, upon which the pre-stress on the hinge forces the lid open.
