MINIATURE PUMP SPRAYER |
摘要 |
A ventless miniature pump sprayer comprises a reciprocable plunger head extending outwardly of an open end of a tubular member divided into an upper sleeve section and a lower container section for a liquid to be sprayed. A dip tube integral with the member extends into the container, and a pump cylinder and hollow inlet tube integral with the member extend into the sleeve section. An integral shipper seal is molded in the inlet tube and a coaxial rod within a hollow piston on the plunger cooperates with the inlet tube for controlling the inlet and, during initial actuation of the plunger, pierces the shipper seal and has a groove or a rib thereon which establishes an air passage through which unwanted air from the pump chamber is ejected into the container to aid in pump priming. |
