Non-replaceable snap on cap for school milk bottles

摘要

A snap on non-replaceable cap for a plastic school milk bottle neck finish with an external annular rib has a top with an inwardly spaced sealing flange depending therefrom, the outer surface of the sealing flange is shaped downwardly and inwardly. A tear skirt having an inturned annular flange forming the peripheral edge of the top is joined to the top by a thin semi-annular tear line. An inturned rib is formed on the inner surface of the tear skirt which locks under the external rib on the neck finish. The tear skirt, including the inturned annular flange may be completely or partially torn away from the top to permit the top to be removed. To facilitate removal, the tear skirt is formed with a second tear line from a lower edge thereof to the thin semi-annular tear line in the top. A pull tab is formed adjacent the second tear line functions as a lift tab to remove the cap. The top and its depending sealing flange prevent the same from being replaced on the bottle.
