<p>A closure (40; 71; 91), for a container (30), comprises a closure member (45; 93) and a key member (45; 94). The closure member (45; 93) includes an opening (51) formed in communication with a concealed sealing member (52; 73). The sealing member (52; 73) is moveable between a closed position towards which it is resiliently biased and an open position. The opening (51) defines a conduit (53) for either dispensing the contents of the container (30) or adding contents to the container (30). The closure member (45; 93) also includes and access channel (54; 97) in communication with the sealing member (52; 73). The key member (45; 94) includes an engagement portion (56) that is co-operable with the access channel (54; 97), whereby the engagement portion (56) is moveable within the access channel (54; 97), so as to move the sealing member (52; 73) into the open position, when the closure member (45; 93) and the key member (45; 94) are releasably engaged together.</p> |
