  • Patent number: 5033634
    Abstract: A child resistant box which is composed of a base, a lid and a hinge connecting the base and lid together. A latching mechanism is located on each of the two sides of the box for releasably retaining the lid to the base. The box can be moved between open, intermediate, and closed positions. The box also includes a means for biasing the lid from the intermediate position toward the closed position. To open the box the lid is compressed to the intermediate position. In this intermediate position, the latching mechanism may be disengaged by exerting manual pressure thereon toward the center of the box. Once pressure is exerted simultaneously on both latching mechanisms the lid is released and the biasing means moves the lid at least partially toward the open position. The operation of this box is particularly well-suited for the elderly.
