Abstract
A tamper evident closure construction is provided for use with a container of the type having a neck with a discharge orifice therein. The tamper evident closure construction includes a dispenser cap and a unitary, one-piece, tamper evident closure cover. The dispenser cap includes a base connected to the neck and a dispensing portion connected to the base. The tamper evident closure cover consists of an overcap and a container closure cap separated by frangible webs which, when permanently disengaged, allow access to the dispensing portion and provide a visual indication of tampering. The container closure cap is fastened directly to the neck of the container and includes a breakaway tamperband, or alternatively, a snap-fit abutment arrangement, which provides an indication of attempts to remove the container closure cap from the neck. The skirt of the container closure cap is directly coupled to the neck of the container, and includes an annular bead on an inside surface and an annular flange which cooperate to secure and seal the base of the dispenser cap against the neck around the discharge orifice.
