ABSTRACT:
A storage case for a video cassette. The case is in the general form at a book and is openable to a flat condition. A hollow wall, blow-molded construction imparts structural rigidity to the case and also provides shock resistance for its contents. The case is formed by blow molding a single, unitary, hollow parison of a thermoplastic material and then pressing two parallel portions of the blow-molded article to form living hinges. Integral resilient latch elements hold the case closed yet permit easy reopening. The case is formed in an essentially single operation.
