| 摘要 |
The invention is a viscous materials dispenser, comprising a housing having side walls defining a hollow interior space, a housing top having a housing top opening in communication with the hollow interior space in which viscous material is contained, and a base. A cap is seated on the housing top where it may rotate, the cap plug extending into the housing top opening. A threaded rod extends from the cap to the base, the threaded rod mated with the cap so that it rotates with the cap. A piston mounted between the side walls advances toward the cap when the cap and threaded rod are rotated. The cap has a lower chamber that extends into the cap plug that is in fluid communication with the hollow interior space through a plurality of polygonal holes, and also has a spout cavity in fluid communication with the lower chamber. The cap has a spout, mounted within the spout cavity and also has a conduit. The spout pivotable within the spout cavity between an open and a closed position to bring the conduit into and out of fluid communication with the lower chamber.
