<p>In a second embodiment, the straw (130) engages a floating member (126) which is urged against the lid (116) of the container (110). When the container is opened by deflecting a closure tab (122) into the container, the closure tab (122) engages a cam surface (134) on the floating member (126) and imparts a rotational motion to the floating member (126). The floating member (126) rotates until the straw (130) is aligned with the open orifice (120) and a buoyant member (128) associated with the straw (130) elevates the straw through the orifice (120).</p> |
