ABSTRACT:
A closure is provided for selectively closing an opening of a container, including a base element arranged to be affixed to a container adjacent an opening therein. In one embodiment, the closure is provided with tamper-evident film fixed to the base element, and a control element is pivotally movable relative to the base element between open and closed positions. When the base element is affixed to the container, the tamper-evident film obstructs the container opening. When the control element pivots to the open position, the tamper-evident film is visible, and can be punctured or otherwise removed. According to another embodiment of the invention, a closure is provided for a container having a tamper-evident film secured thereto overlying the opening in a container. The closure includes a control element having a puncturing element which is operable upon being pivoted in an inward direction to puncture the tamper-evident film to provide access to the container contents, and to provide an indication that access to the container has been had.
