A method of forming a bi-injected closure (110), comprising the steps of: forming a cap (115) with a top plate ( 125) and a depending sidewall ( I 30) in a first injection moulding phase using a first mould part (175), the cap formed so as to include one or more external sealing areas (132, 146); changing the first mould part (175) for a second mould part (185), the second mould part sealing against the or each sealing area on the cap; and forming an outer ring (120) around the cap sidewall (130) whilst the second mould part is sealed against the sealing area/s (132, 146) in a second moulding phase. |
