composite capsule closure step, with highlighting of tampering

摘要

There is described a composite closure cap in which a metal cover or panel portion (12) is inserted from the top end in a lateral ring or skirt portion (10), plastic molded and joined, at its opposite end, to a tampering evidencing band (28) by means of breakable bridges. The cap is characterized in that at least one jut (32), designed to be engaged by hand to open the packing, is provided on the outer surface of the ring portion, and locking means are circumferentially located on the inner surface of said ring portion to cooperate with a bead (24) of the container (26) to keep the packing sealed.
