Abstract: A molded plastic container/closure combination providing a tamper evident feature, a child resistant feature and a removal facilitation feature. The closure has radially extending bayonets extending from the outer skirt which fit into horizontal slots in a beam molded integrally with the sidewall of the container. Rotation of the closure in one direction brings the bayonets into the slots for locking purposes. Rotation in the opposite direction unlocks the closure and continued rotation lifts the closure relative to the container to facilitate removal. A resiliently mounted release tab must be depressed before unlocking rotation is permitted. A latch prevents depression of the release tab until anchors on the sides of the latch are fractured. Serrations acting between the tab and the bayonets provide an audible indication of rotation.

Abstract: A cake container having a base (14) and a transparent cover (16) lying over the base, both being constructed of heat-formed plastic sheets, with peripheries of the base and cover securely latched together in a way that avoids sudden movement during unlatching.
