Plastic stopper for e.g. wine bottles - consist of e.g. foam body in two halves joined together by horizontal gas barrier of e.g. foil coated each side with polyethylene

A stopper for bottles, and partic. for wine or champagne bottles, has a plastic stem with gas-tight barrier layer. This stem is solid; the barrier layer runs at right angles to its axis and divides the stem into upper and lower halves. The barrier can be made of polyester-coated aluminium and the body sprayed-on foam. Specifically, an exploded view of a stopper for wine bottles shows that it consists of an upper (2) and a lower (3) part with the barrier layer (4) between. The top and bottom (2,3) are made of e.g. ethylene-vinyl acetate and the barrier (4) is alumnium with a thin layer of polyethylene on each side (5,6). The polyethylene films (5,6) are bonded on hot. The structure indicated is pressed together into one place. In this the two parts (2,3) stay bonded together even if subjected to torsinal forces. A champagne type of stopper (or for e.g. sherry) has a similar construction with a bevelled bottom edge and a wiper top head. ADVANTAGE - The prod. provides an effective gas barrier ...

APPARATUS FOR PRODUCING SCREW-THREADED INJECTION-MOULDED ARTICLES

METAL CAN ENDS WITH METAL PULL TABS BONDED THERETO

METHOD AND MOULD FOR A CAP WITH A TAMPER-EVIDENT BAND

The cap made in the mould of the invention comprises a skirt (14) attached to a band (20) by frangible lugs (30). The band has angularly spaced inward projections (21) for engaging over a bead on a container. The cap can only be removed from the container by breaking the lugs leaving the band on the container. The top faces of the projections (21) which engage the bead are perpendicular to the axis of the cap to provide secure captivation. This is produced by moulding each projection between a mould core (40) and a slidable mould part (60). The part (60) has a boss (61) defining a face (62) perpendicular to the cap axis for forming the top face of the projection. The end face (63) of the boss is tapered outwardly from the perpendicular face (62) and contacts a complementary face (43) of the mould. The lugs are formed between the bosses. Each projection (21) slides up the corresponding complementary face (43) as the stripper (70) strips the cap off the core, thereby preventing damage to ...
