  • Patent number: 4577783
    Abstract: A dispenser for high viscosity fluid materials is disclosed which includes a container of predetermined inside diameter, a selectively operable valve means providing, in open condition, an outlet flow passage for a fluid material and propelling means for forcing the fluid material through the flow passage and out of the container. The propelling means comprises a follower plate disposed in contact with the fluid material and mounted for movement toward the valve means to force the fluid material out of the container. The configuration, the structure and dimensional relationships between various portions of the follower plate are carefully controlled to provide a unique, dependable and effective fluid material discharge from the container as the follower plate is moved toward the open valve means.
