Container cap having rounded retainer bead sections

Abstract

A container having a neck formed with external shoulders and grooves below the shoulders is closed by a plastic cap having a depending skirt formed with interrupted internal beads which lock under the neck shoulders and are received in the neck grooves. A circumferential scoreline is formed in the skirt above the lower bead and is connected to a second scoreline which extends down to the lower edge of the skirt. Adjoining the terminus of the second scoreline is a tab which may be gripped and pulled to tear the skirt upward along the second scoreline and then circumferentially around the first scoreline to remove the lower part of the skirt and make it possible to remove the remaining portion of the cap. The improvement consists in making the bead sections in various truncated conical shapes distributed in various patterns. These shapes facilitate application of the cap to the neck without splitting the former or crushing the latter. The conical shapes may be circular or elliptical in cross-section and may be aligned or staggered.
