ABSTRACT:
A device (10) for cleaning the inside of a container includes a base (11) carrying a tube (12). A hose (50) is received within the base (11) and is connected at one end to the bottom of the tube (12) and at the other end to a source of water via a quick disconnect assembly (60). A spray head (21) houses a plunger (30) which has a base (31) and a nose (32). A spring (37) urges the nose (32) of the plunger (30) out through an aperture (40) in the spray head (21). A flat washer seal (42) is positioned with a majority of its surface on a shelf (41) formed in the spray head (21). Ribs (43) on the shelf (41) engage the seal (42) on one side, and a rim (44) on the base (31) engages the other side of the seal (42). The quick disconnect assembly (60) includes a valve (66) which is maintained closed by a spring (67) so that when the hose (50) is disconnected from the source of water, or the water supply pressure is lost, backflow is prevented. When a container is inverted and its bottom pushed down on the top of the nose (32) of the plunger (30), the base (31) of the plunger (30) is moved away from the seal (42) to allow water to be emitted from spray head (21) through axial apertures (70) and radial apertures (71).
