Abstract

A can end (1) having an openable portion (14) defined by a score line (13), has a ring pull defining an aperture in which is retained a token (16) which may be removed as proof of purchase to qualify the purchaser for a prize or other premium offer. The token (16) is preferably made from a plastics material which is retained by clinching of peripheral material of the ring pull, and may be marked with indicia.

Claims

1. Apparatus for retaining a token on a lever or ring pull said apparatus comprising:

(a) means to feed a strip of material including token portions to a parting station;

(b) a parting station at which the token portion is severed from the strip of material;

(c) means to transfer the parted token to a location in a partly formed lever or ring pull; and

(d) means to clinch a peripheral portion of the lever into clinched engagement with a peripheral portion of the token.

2. Apparatus according to claim 1 wherein the means to part the token portion from the strip is a punch and die so arranged that after parting the token from the strip the punch pushes the token through die and into engagement with the partly formed lever or ring pull.

3. Apparatus according to claim 1 wherein the apparatus further comprises means to convey the lever or ring pull with token attached to a station at which the pull ring is rivetted to a can end.

4. Apparatus for retaining a token on a lever or ring pull, said apparatus comprising:

(a) a parting station at which a token portion is severed from a strip of material; and

(b) means for clenching a peripheral portion of the lever into clenched engagement with a peripheral portion of the token.
