  • Patent number: 5429240
    Abstract: A reclosable light-tight container for storing a plurality of sheets of light-sensitive material includes a lower wall, an upper wall, and a plurality of side walls. A door is formed as part of the upper wall, and a door hinge permits the container to be opened and closed. A reclosable light-tight closure is created by an unbroken wall formed on the inner surface of the lower wall and extending around and enclosing the portion of the inner surface corresponding to the door location when the door is closed. A raised platform on the inner surface of the upper wall door has a top surface which abuts the inner surface of the lower wall outside of the unbroken wall when the door is closed. The raised platform blocks light from entering the container by covering the parting line between the unbroken wall on the lower wall and the upper wall. A tab on the unbroken wall blocks light at the door hinge.
