Abstract
A snap on non-replaceable cap for a plastic bottle neck has an upper skirt and an inwardly spaced sealing flange, the inner opposed surfaces of the upper skirt and the sealing flange are curved downwardly and away from one another. A tear skirt is joined to the lowermost edge of the upper skirt to form a thin circumferential tear line. An inturned rib is formed on the inner surface of the tear skirt which locks under an external rib on the neck. The tear skirt, including the inturned rib, may be completely or partially torn off to permit the cap to be removed. To facilitate removal, the tear skirt is formed with a vertical tear line from the lower edge thereof to the circumferential tear line. A tab formed adjacent the vertical tear line functions as a lift tab.
