Abstract
Apparatus for cleaning hoses used by a dentist in the course of his work has a container having a mouth and a top adapted to snugly cover the mouth of the container. The top includes at least one nozzle protruding upwardly from a surface of the top to the exterior of the container, the nozzle having an internal bore through which fluid in the container may pass and the nozzle sized to fit snugly within a hose attachment attached to the end of an external suction hose so that the hose may be connected to the nozzle via the hose attachment. The top also includes an internal tube attached firmly to the nozzle and extending into the lower interior portion of the container, so that the unattached end of the internal tube is immersed in the fluid. The application of suction to the external suction hose causes the fluid in the container to be drawn through the internal tube, the nozzle, and then the hose, thereby cleaning the hose with the fluid.
