Abstract
A tamperproof press-on, snap cap for closing a container having a neck defining the mouth opening. The container has an upper cap retaining bead and lower, enlarged annular ledge. The snap cap includes an enlarged end wall and a downwardly depending skirt inwardly of the end wall periphery which has an inwardly directed radial annular bead for cap retaining engagement with the container bead. A cylindrical tear sleeve depends downwardly from the peripheral edge of the end wall of the cap, is spaced radially outwardly from the skirt, is longer than the skirt and sized for encircling and snugly engaging the annular ledge. The tear sleeve has a peripherally weakened annular tear zone at the cap end wall juncture and includes an axial tear groove extending from the weakened tear zone to the lowered edge of the sleeve. Adjacent the tear groove is shortened section to enable grasping and tearing the sleeve. Two alternative forms of cap end wall are shown, the first a solid end wall providing a one-piece cap, the second, an apertured end wall useable with a two-piece closure wherein an underlying lid seals off the mouth of the container and is held by the overlying cap.
