Abstract
The closure has a tear band (3) connected to a cap by a fragible line of weakness comprised of spaced apart relatively strong nibs (6) separated by weak sections. The nibs are of relatively thick material. A skirt (2) is connected to the tear band by the weakness line. The tear band is connected to an anchor band by a second tear line also consisting of nibs and weak sections. The nibs in the second tear line are displaced vertically w.r.t. the nibs in the first. Each weak section is in the form of a fine web (7) interconnecting adjacent ribs.
