Abstract: A cap of a type having a top disk with depending outer and inner skirts between which the neck of the jar fits is disclosed. The inner surface of the outer skirt and the outside of the neck have cooperating upper and lower locking beads holding the cap in place until the lower portion of the skirt is torn off by tearing along a horizontal score line and thereby removing the lower cap locking bead. The skirt is torn by pulling a tab horizontally. The tab in one form of the invention is defined by cutouts in the lower portion of the outer skirt and is offset outwardly for easy engagement by the finger of the user. In a modification there are two tabs extending in opposite directions, either of which may be pulled to tear off the lower skirt and both tabs being joined by narrow links to a central release lug. The latter is bent upward, thereby breaking the links. The lug has an additional utility in prying off the cap from the neck of the jar after the lower skirt is torn off.
