<p>PCT No. PCT/GB89/00409 Sec. 371 Date Dec. 18, 1990 Sec. 102(e) Date Dec. 18, 1990 PCT Filed Apr. 19, 1989 PCT Pub. No. WO89/10270 PCT Pub. Date Nov. 2, 1989.A first cup member (4) has (a) a first channel (18) which passes radially from the center of its bottom panel (6) along the inside surface of said bottom panel (6) and substantially axially, upwardly 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) at an edge of the 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) for moving the opening (20) to the lowest point in the second cup member (10). 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), second channel (22), first channel (18) and outlet (16). The two cup members (4, 10) are easily separated providing access to the channels (18, 22) to facilitate cleaning.</p> |
