Anti-rotational and removal closure
A closure for use with a container in which the closure includes a polymeric top portion and a polymeric annular skirt portion. The skirt portion depends from the top portion. The skirt portion includes exterior and interior surfaces. The interior surface of the skirt portion includes crushable ribs and anti-rotational lugs. The crushable ribs are configured to be crushed when the closure is applied to the container so as to prevent or inhibit axial movement of the closure with respect to the container by forming an interference fit. At least one of the plurality of anti-rotational lugs prevents or inhibits rotational movement of the closure with respect to the container such that the closure remains on the container.
