<p>A first cup member (4) has (a) a first channel (18) which passes radially from the centre of its bottom panel (6) along the inside surface of said bottom panel (6) and axially or substantially axially along the inside of its wall(s) (8) and (b) an outlet (16) which communicates with the first channel (18) at a point remote from said bottom panel (6). A second cup member (10) has an opening (20) in its bottom panel (12) which communicates with a second channel (22) which passes radially along the outside surface of its bottom panel (12). The second cup member (10) is positionable within the first cup member (4) such that the first and second channels (18, 22) are always in communication with one another regardless of relative alignment of the first and second cup members (4, 10), such that a fluid held within the second cup member (10) can flow through the opening (20), first channel (18) and outlet (16).</p> |
