Abstract: A pull tab spout for a bottle neck has a tubular inner member having a bottle end opposite a pouring end, the bottle end being configured to sealingly engage the inner wall of a neck. A skirt extends about the bottle end of the spout outwardly thereof to define a recess for receiving the mouth of the bottle. A shoulder extends between and joins the skirt to the inner member and defines a guide surface for guiding a rim of a closure cap onto an outer face of the skirt. The outer face of the skirt has outwardly extending threads for engaging corresponding inwardly extending threads of the cap. The skirt has at least one inwardly extending protrusion to secure the spout to the bottle. A pull tab extends across an interior and is secured by a frangible membrane. The pull tab has a graspable protrusion to facilitate removal of the pull tab by tearing the frangible membrane.

Abstract: The invention provides a motion transfer mechanism for transferring motion between a first and second component, the mechanism comprising an elongate track mounted to the first component, the track having a polar axis and an external actuation surface along a portion of the length of the track, the track having at least one portion of the actuation surface inclined at a predetermined spiral angle about the polar axis; track riding device, mounted to the second component in guided contacting relation with the actuation surface, for longitudinal displacement relative to the actuation surface, and for predetermined rotational displacement in response to the longitudinal displacement, the track riding device comprising: an actuating surface follower mounted within a rider housing; and biasing device disposed between the follower and the housing for resiliently urging the follower into continuous engagement with the actuation surface; track mounting device for mounting the track to the first component in predeterm
