CAP CLOSURE

摘要

A bottle is formed from a moulded plastics body and an injection moulded nec k and cap assembly which can be fused to the body after the body has been fill ed with a fluid. The body may be provided with a relatively wide mouth to enhan ce the filling speed. The bottle is particularly suitable for blow moulding in a plant adjacent to a dairy where it will be subsequently filled with a fluid and fused to a pre-sealed neck and cap assembly in a single continuous operation. A foil (70) is interposed between the body and the neck and cap assembly. The neck comprises a base (20) fitted to the body with a removable annular flange (30) connected to a pull ring (42) and secured to the foil (70). A frangible region (32) separates the removable annular flange (30) fr om the base (20). A plurality of depending teeth (36) each having a saw tooth profile inclined inwardly to a centre of the base are formed in the base adjacent to or in the frangible region (32) such that on removal of the pull ring (42) the foil (70) is torn by the teeth. The base may be provided with a weakened annular recess (48) that is concealed by a skirt (58) of a cap (50) when the closure is sealed. This recess (48) causes the base to break and th e cap closure to be destroyed if any attempt is made to prise the base (20) fr om the mouth (6) of the bottle. This provides tamper evidence by destruction of the closure.
