Abstract
A trigger sprayer apparatus is comprised of a sprayer housing and a vent housing that are formed independently of each other and are then assembled together. By providing a separate sprayer housing and vent housing, the sprayer apparatus may be produced in a manner that significantly reduces the occurrence of deformations or imperfections in the component parts of the apparatus. Molding the sprayer housing and vent housing separately enables the cylindrical interior surface of the pump chamber and the cylindrical interior surface of the vent chamber to be molded more accurately.
Because the sprayer and vent housings are molded separately, a lesser amount of material is needed to mold each of these components and therefore shrinkage of the material as the components cool is significantly reduces.
This eliminates the occurrence of deformations or sinks in critical areas of these component parts.
