A crown particularly adapted for use with a liquid refreshment container wherein the crown is adapted to be turned off the threads on the container or pried off the container with a bottle opener. The crown has a smooth edge configuration so that it can be readily grasped by the fingers for turning without the fingers being cut by the sharp edges which are normal with a conventional serrated crown. The smooth edge configuration for the crown is secured by forming a lip portion on the peripheral edge of the crown. The crown may be formed by a forming die which provides the lip configuration at the same time it crimps the skirt of the crown, or a conventional crown may be forced through a sizing die to provide the lip configuration.
A seal and closure for a container end includes a metal foil seal having a cylindrical part sealed to the inner surface of the container adjacent the end, a transverse diaphragm part recessed inwardly from the end, and a tear tab on the diaphragm. An annular groove is formed in the cylindrical part between the container end and the diaphragm, the groove defining a tear line so that the membrane and the inward portion of the cylindrical part separate from the remainder thereof when the tear tab is pulled. An insertable lid covers the seal.
A die stamp formed disc construction including a toothed plate and a two-stepped sleeve integrally formed thereon. The sleeve has coined or stamped interior and exterior forty-five degree flats. The flats are accurately positioned so that, with the discs received through their central openings and clamped together onto the rotation shaft, the interior flat of one disc is held directly against the exterior flat of the adjacent disc thereby accurately and consistently positioning and holding the toothed plates of adjacent discs in spaced relation and preventing disc wobble.
