A cap of the type having a top portion with a depending annular flange on its peripheral edge and a depending annular sealing flange inwardly thereof between which the neck of the container is sealingly engaged is disclosed in which an annular depending flange of the cap has a lower annular portion offset outwardly for registry with a similarly shaped neck finish of the container. An upstanding tab is integrally formed on the lower annular portion of the depending annular flange. The inner surface of the annular depending flange and the outer surface of the neck finish have cooperating upper and lower locking ribs and grooves holding the cap in place until a major portion of the depending annular flange and its lower annular offset portion are removed by tearing along a horizontal frangible line which removes the lower cap locking rib. The horizontal frangible line has a depending portion adjacent the upstanding tab and a downwardly curving frangible line extends therefrom to the lower edge of the lower annular offset portion. The removable portion of the depending annular flange and the lower annular offset portion form a tear skirt which must be removed from the neck finish of the container in order to remove the cap therefrom. A downturned tab is formed on the remaining portion of the depending annular flange to provide for easy engagement by the finger of the user.
