Abstract
Abstract A container closure assembly for a container comprising an outer cap of generally cup-like form having a top and a skirt depending from the outer peripheral edge of the top and means for detachably securing the same over the opening in a container, an annular pocket formed in the skirt of the outer cap adjacent said top and a liner assembly consisting of at least a disc-like core of a resilient material, a shell for the core having a portion confronting the inside of the top of the outer cap and a locking portion to hold the core in said shell, said shell being of a predetermined dimension to permit limited axial movement in the pocket in the outer cap and anti-friction means between the shell and outer cap to permit relative rotation between the outer cap and the liner assembly.
