PATENTS ABSTRACT OF THE DISCLOSURE A push on cap for engaging a container neck is formed with inturned thickened flanges on its inner surface which cooperate with matching grooves in the container neck to retain the cap in place when the skirt is intact. A circumferential groove is formed in the skirt intermediate the inturned thickened flanges joined with a second groove extending to the bottom edge of the skirt. A tab projecting beyond the skirt is gripped and pulled causing the skirt to tear upward and then circumferentially thereby removing the lower thickened flange and permitting the top of the cap to be removed and reclosed. A rigid circumferential flange on the exterior of the skirt is spaced above the level of the uppermost inturned thickened flanges and below the top of the cap has a angled gusset below the image to prevent removing the cap by prying upwards with a fingernail prior to removing the tear skirt. The addition of the rigid circular flange and gusset and the uppermost thickened flange do not restrict the cap from expanding when pressed over the neck of the container due to the thin wall formation of the circumferential skirt of the cap.
