Spray product and pump to supply air under pressure to the dispenser

摘要

A dispenser having a manually-operated dispensing valve assembly has a container for accommodating a spray product. The bottom of the container has a recess adapted to cooperate with a tube used to deliver air under pressure from an air pump into the container. The container includes a check valve which allows air to flow into the chamber of the container and prevent the flow of air out of the chamber of the container. When the container is placed on the air pump, it actuates a switch which energizes an electric motor which drives a pump for supplying air under pressure which is directed to the tube and into the chamber of the container past the check valve.
