Abstract

A tamper evident container (10) having an opening (15) to allow access to the container contents. Undulations (16) are formed in the rim (14), and a seal (18) is glued across the opening to cause destruction of the seal in gaining access to the container contents. A replica (24) is illustrated on the bottle label for comparison to the seal (18) on the bottle for assurance the container has not been opened.
