A rigid cover (10) includes a first (15) inlet opening for liquid and a second (16) inlet opening for a suction conduit. A flexible pouch with base (21) and opening (22) portions may be sealed against the lower surface (11) of the cover for communication with the two openings in the cover. The opening in the pouch includes a threaded portion (25) which cooperates with a threaded flange (19) on the underside of the cover. A safety cap (40) is attached to the lower end of the suction conduit, incorporating a hydrophobic filter element (42), to block the conduit when liquid in the pouch reaches a predetermined level. |
