ABSTRACT:
A delivery system for dispensing controlled amounts of liquid or powder has two slidingly engaged parts which are held together as a single unit. The system is closed by pushing one of the two parts toward the other until a valve plug in the upper part of the system is received within an aperture of a valve seal membrane in the lower part of the system. The system is opened by pulling one part of the system away from the other using the sliding engagement means so that the valve plug exits the aperture in the valve seal membrane. Interior contoured walls prevent undesired collection of powder within the system, the relative orientation of the two parts of the system is adjustable to control the rate of flow of powder, and the system is particularly suitable for introducing powdered desiccants into medical waste containers without exposing the contents of the waste containers to the surrounding environment.
