Abstract

A cap for opening and extracting the contents of a vessel provided with a neck and an extraction end closed by a removable attachment connected to the vessel neck by a weakened zone, the cap having an open end for engagement over the vessel neck whereby rotation of the cap relative to the vessel neck causes the attachment to be separated from the vessel neck at the weakened zone so that the contents of the vessel may be removed through an extraction opening in the cap.
