Abstract: A tear-off closure is provided which has a top end wall and a depending skirt and having a tear strip defined by scoring divisive of the end wall and into the skirt, the tear strip having at least one embossed rib therein which extends from a location toward the center of the closure radially outward to a location adjacent the shoulder of the closure between its end wall and the skirt to ensure severance of the tear strip over such shoulder of the closure. The closure may further have a raised rim around a recessed central panel in its top end wall, with the rib in the tear strip extending from the recessed central panel into the rim of the closure.
