<p>An injection moulded, plastics material cap (1) for a screw top bottle has a top and a skirt with an anti-tamper band (2) connected to the skirt at a tear-off line by links (3). On the inside of the top of the cap, a depending annular ridge (10) is provided. Its inside diameter is such that it abuts and seals on the outside diameter of the distal end of neck of the bottle. Also on the inside of the cap, inside the ridge (10), is moulded a forked feature having an inner limb (12) which extends generally downwards with an outwards bias, and an outer limb (13) which extends generally outwards with downwards bias. The inner limb is dimensioned to fit inside the mouth at the neck of the bottle, sealingly engaging it, whilst the outer limb is dimensioned to abut the end of the neck, also sealingly engaging it when the cap is screwed tight.</p> |
