Abstract

Abstract An integrally formed, one-piece, generally rectangular, plastic container particularly adapted for holding medicines is disclosed. The container includes a generally rectangular bottom section which is connected to a rectangular top section by means of an integrally formed, flexible, plastic hinge at the rear of the two sections. In the closed position, the top section overlies the bottom section and latch means lock the two sections together. The closed container requires that equal pressure be applied to the rear corners thereof in order to disengage the latch means. The container provides a substantially childproof safety closure for tableted medicines such as aspirin, laxatives, cold tablets, prescription drugs, etc.
