Abstract
An overcap is provided for use with a hermetically sealed container which includes at least an external thread on a peripheral portion of the container, a cover portion closing the container, and a frangible web joining the cover portion to the container threaded portion. The overcap has a closed end, an open end, and at least a generally cylindrical inner peripheral portion oriented about a longitudinal axis with an internal thread on the interior of the overcap. A plurality of flexible fingers is provided on the interior of the overcap and project from the overcap between the overcap thread and the overcap closed end. Each finger projects inwardly toward the longitudinal axis and toward the closed end to accommodate the screwing of the overcap onto the container so that the overcap is operable upon rotation in the unscrewing direction to exert an axial force against the cover portion to fracture the frangible web for removal of the cover portion.
