Abstract
A tamper evident container assembly for packaging of dairy and other food products. A container is provided with a closure comprising an end board, a downwardly extending peripheral skirt along an edge of the end board and an upturned locking ring projecting inwardly from a bottom edge of the skirt. The locking ring engages the container rim and prevents removal of the closure while the locking ring is in place. The skirt and locking ring are integrally molded with the end board being attached to the skirt subsequent to the molding process. The locking ring and a portion of the skirt may be severed from the remainder of the skirt along a score line to permit removal of the closure after initial application to the container. Removal of the locking ring provides a visual indication of possible product tampering.
