ABSTRACT:
The dispenser consists of a container which contains a portion of a paste-like material. The dispenser has an internal check valve and an internal spring for biasing the dispenser actuator. At the lower part of the container is a piston which moves upwardly as the paste-like material is dispensed from the container. This dispenser due to the flow of material can be adapted to put stripes onto the main paste-like material stream. In addition, the dispenser can be adapted to function as an atomizer. As an atomizer, a tube will extend downwardly from the pump head to the bottom of the container. Also, the discharge spout will have an atomizing orifice.
