    摘要: A spray pump comprising a main cylinder and a secondary cylinder with a main piston and a secondary piston, first and second springs are provided for urging the pistons to particular positions. A fixed attachment between the main piston and the secondary cylinder and the latter forms a space with a closed bottom and an open upper end through which the interior of the main cylinder and the secondary cylinder are in communication.

    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 tie 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.

    摘要: A precompression pump sprayer has a stationary discharge and a reciprocable pump cylinder which squeezes the air out of the pump chamber to facilitate priming as the cylinder is plunged relative to a piston shifted by the plunger to open the discharge during priming. Once primed the piston is shifted to open the discharge upon a build up of pressure during plunger reciprocation. A container vent is controlled by operation of the plunger.
