ABSTRACT:
A child-resistant closure for a liquid container having a threaded neck. The closure comprises an inverted cup-shaped cap which has a shirt and on the inner side of its skirt has a thread that mates with the neck thread. The child-resistant means consists of an outwardly extending ring attached to the end of the skirt by frangible webs. The ring has a gap that is defined by an abutment at one end and a stop at the other end. A tab which permanently is connected to the cap skirt lies in the gap. The cap, ring and tab are unitary and are turned onto the neck to liquid sealing position at which time the ring engages a shoulder formed on the container at or near the base of the neck. The ring is then affixed to the shoulder. The container is opened by flexing the tab upwardly above the level of the abutment on the ring and rotating the cap and tab in a retrograde direction relative to the ring which breaks the frangible webs. When the cap is again rotated onto the container neck until the tab moves into the gap in the ring, the cap is restored to liquid sealing position.
