Abstract
A commercially available seal disc of foil or thin plastic is inserted in a temper-evident plastic bottle cap prior to its being applied to a container neck. The cap has an internal, horizontal upper locking bead as well as a lower locking bead which lock under shoulders on the neck of the container. Inward-extending lugs are formed projecting inward of the upper locking beads to augment the bead sections in retaining the seal disc inside the cap. When the cap is applied to the container neck, the seal disc adheres to the container neck. Neither the internal cap beads nor the lugs interfere with retention of the disc on the neck as the cap is removed.
