ABSTRACT:
The present invention is directed to a lug cap or closure that is used in combination with a container for indicating that the container has been opened so as to indicate loss of seal or tampering. The lug cap includes an upper cap portion and a depending tamper or pilfer band, each having a series of circumferentially spaced lugs. The upper cap portion and the pilfer band are joined by a plurality of frangible bridges. The container finish includes combination camming/locking projections for locking the lugs into a locked position and for separating the pilfer band from the upper cap portion by a camming action when the container is opened. The lug cap may also include a secondary tamper indicating means such as a tamper indicating button in the top of the lug cap.
