Abstract
A closure for a recipient having an upwardly open annular neck centered on an axis and formed with an external attachment formation and an axially downwardly projecting shoulder has a unitary one-piece cap formed of a relatively soft synthetic resin and a unitary one-piece tamper-resistant ring formed of a relatively hard synthetic resin. The cap itself is formed with an end sealingly fittable over the neck and an annular skirt projecting axially from the end and formed internally with an attachment formation complementary to that of the neck. The skirt has remote from the end a rim and is formed between the rim and the end with a radially inwardly open groove. The tamper-resistant ring is formed with an annular upper part having an outwardly projecting ridge normally seated in the groove of the skirt, an annular lower part having an inwardly projecting lip fitting axially under the shoulder of the neck, and a relatively fragile web axially joining the unitarily formed with both parts.
