摘要：A reusable closure for an opening in a container (1) defined by at least one upstanding wall having an inner and an outer surface, the closure including: a top (8) to cover the opening; at least one pair of downwardly projecting arms (12) to define a cavity to receive the outer surface of the at least one upstanding wall adjacent the opening and biasing means to bias the pair of arms towards one another. The biasing means includes a ring member (24) or disc engageable in an upwardly directed cavity defined by at least one pair of upwardly projecting arms (19), the ring member (24) or disc dimensioned to urge the arms (19) outwardly to in turn urge the arms (12) inwardly. Inwardly directed claws of the arms (12) engage under a flanged portion (6) of the upstanding wall whereby the closure is captured about the neck (2) of the container. A sealing means (15) seals against the inner surface of the upstanding wall, being urged into sealing engagement by downward and outward movement of a diaphragm constituting the top (8). In an alternative arrangement the downwardly projecting arms (12) and sealing means (15) are urged towards one another by means of a ring member engaging in an upwardly directed cavity defined by upwardly projecting outer and inner arms located above and adjacent the downwardly projecting arms and sealing means, the ring member dimensioned to urge the upwardly projecting outer and inner arms respectively outwardly and inwardly to in turn urge the downwardly projecting arms and sealing means respectively inwardly and outwardly.
