Abstract: A liquid dispensing system which is designed to use a single pump in conjunction with a plurality of liquid containing containers. The pump can be either manually or electrically operated. Associated with each container is a dispensing valve which prior to usage is closed by a cap preventing leakage of liquid from the container. Once the cap is removed a connector on the pump can be matingly connected to the dispensing valve in a liquid tight manner and subsequent operation of the pump will cause dispensing of the liquid into the ambient. The pump can be covered by a cover which is fixed to the container. An access opening is provided within the cover so as to manually operate the pump. An outlet tube extends from the pump to an outlet hole in the cover. This outlet tube flexes during operation of the pump. The pump and container can be formed into a pistol type configuration.

Abstract: An air treatment apparatus operating in conjunction with a conventional type of air conditioning apparatus through which air moves in an air stream. The air treatment apparatus is to be loaded with any one of a plurality of interchangeable cassette type containers. Each container is to contain a particular type of a liquid substance such as an air freshening chemical. The air treatment apparatus is to be electrically controlled to operate through a pump to be dispensed as a plurality of short bursts of the substance within the air stream of the air conditioning apparatus at preselected intervals.
