ABSTRACT:
A tamper resistant closure member adapted to be affixed to a dispensing container includes an inner housing affixed to the opening of the container. The inner housing has an opening and a recessed portion about the opening. A leaf member is positioned over the opening within the recess and is secured about its edge surface to the inner housing. An outer housing is rotatably nested over the inner housing. The outer housing includes an opening and a projection adjacent the opening. The projection is adapted to be received within the recess to engage and substantially close a leaf member as the opening of the outer housing is rotated in communication with the recess.
