CONTAINER CLEANING DEVICE

摘要

A device for cleaning the inside of a container includes a base carrying a tube. A hose connects the tube to a water source via a quick disconnect assembly. A spray head houses a plunger. A spring urges the nose of the plunger out through the spray head. A washer seal has a majority of its surface on a shelf formed in the spray head. Ribs on the shelf engage the seal on one side, and a rim on the base of the plunger engages the seal's other side. The quick disconnect assembly includes a valve which is maintained closed by a spring so that when the hose is disconnected from the water source backflow is prevented. When a container is pushed down on the plunger nose, the plunger base moves away from the seal to allow water to flow from axial and radial apertures in the spray head.
