Abstract

A plastic closure is disclosed which has an integral sealing means formed by an annular resiliently deflectable V-shaped wall section with a downwardly and outwardly projecting corner on it for sealing against an upwardly facing sealing surface on a container. The closure also has a stop member projecting downwardly and inwardly from near the top of the closure skirt for engagement against the container mouth during application of the closure on a container to arrest the axial travel of the closure on the container. The closure may have paraffin or wax lubricant either in the plastic material of the closure or on the inside surface to reduce the torque required to seal the closure on a container.
