Abstract
A crown closure and container comprising a glass container having a crown finish without threads, a closure comprising a rigid plastic outer shell and an inner cup-shaped liner. The outer shell comprises a top panel and a peripheral skirt. The liner is made of soft resilient plastic material and comprises a top wall and a peripheral wall. Interengaging cam surfaces are provided between the inner surface of the skirt of the shell and the outer surface of the peripheral wall of the liner such that when the closure is applied to the crown finish by an axial motion of the closure relative to the container, the liner if forced into the shell and the upper portion of the liner engages the crown finish of the container. The peripheral skirt of the outer shell is formed with threads so that the upper portion of the liner is forced into the threads and will allow for sufficient interference with the liner and finish to permit removal of the closure by rotation of the shell in relation to the liner.
