A package (10) comprising a belt (42) extending between a first end (37) and a second end (39) of a belt path; and first and second tab members (14, 16) attached to the belt (42) such that when the first tab member (14) is moved in a first direction, the second tab member (16) is driven by the belt (42) to move in a second direction different to the first direction. The tab members (14, 16) are attached to the belt (42) by respective bonds (45, 46), the movement of the tab members (14, 16) in either direction being delimited by at least one bond reaching an end of the belt path; and when at least one of the tab members is in a closed position, said bond is positioned inwardly from the ends of the belt path so that said tab member can move in both the first and second directions from the closed position before the bond reaches an end of the belt path to delimit said movement. |
