Abstract
Abstract A wide-mouth jar of plastic or glass has an exterior neck finish comprising two circumferential, vertically spaced buttressed beads, the lower being of greater diameter than the upper. The plastic cap which fits on the neck has a flat-top disk with a peripheral skirt, the interior of which is formed with two circumferential beads dimensioned to engage immediately under the radial flanks of the beads of the neck. The wall of the skirt is weakened immediately above the lower cap bead in a circumferential internal groove which connects with two downward slanted internal grooves extending to the bottom of the skirt. A first finger grip tab depends from the bottom of the skirt to one side of the slanted groove to tear the cap along the grooves. A second tab depends from the bottom of the skirt between the downward slanted grooves to pry the cap off the neck.
