ABSTRACT:
A closure (5) suitable for mounting onto a container (80). A closure comprises a main closure (10) having a top portion (11) that has an aperture (32) therethrough and a skirt (12) depending downwardly from the top portion (11) that is attachable to the container. A sealing rib (16) extends inwardly from the inner surface of the main closure (10) and is adapted to form a seal with the end portion of the container (80). A spout (33) extends upwardly from the top portion (11) and defines a bore that is in fluid communication with the aperture (32) in the top portion (11). A plug (36) having radially outer surface is mounted to the spout (33). The closure further comprises a top cap (50) that is mountable to the spout and is relatively movable between a first position where the plug (36) seals an opening in the top cap (5) and at least a second position where the plug (36) is withdrawn from the opening. On relative movement of the top cap (50) from the first position towards the second position, a sealing member (59) of the top cap (50) rides up over one or more protuberances (40) extending outwardly from the spout so as to at least partially release the seal made by the sealing member (59) with the spout (33).
