摘要： A manually operated reciprocating liquid pump of the type comprising a plunger that reciprocates vertically in a pump chamber to dispense liquid from a container to which the pump is attached includes a vent opening to vent air to the interior of the container as liquid is drawn from the container by the pump. The pump plunger locks in its vertically downward position in the pump chamber and is provided with a stopper that plugs the vent opening and prevents liquid in the container from passing through the vent opening when the plunger is in its locked position.

摘要： A manually operated pump sprayer that does not leak contents through the air inlet vent port during operation when the bottle is oriented so that the inlet vent port would be covered with liquid in a spray bottle to which the sprayer is mounted. The pump sprayer is devised as having an air inlet unit which includes the air inlet vent port in liquid communication with an extension tube which in turn is in liquid communication with a storage volume which in turn is in liquid communication with a liquid control orifice. An entrance end to the tube is positioned at a location farthest from the discharge exit opening of the sprayer, and the liquid control orifice is positioned closer to the exit opening such that when spraying in a downward direction such entrance end is always above the liquid level in the storage volume. Otherwise the entrance end is arranged as to be closer to the exit opening compared to the liquid control orifice such that when spraying in an upward direction the entrance end is above the liquid level in the storage volume.

摘要： A high pressure manually-actuated spray pump for dispensing a fluid. The spray pump comprises a nozzle through which the fluid is dispensed and a pumping engine. The pumping engine comprises a reservoir, a closure, and a plunger. The reservoir has an open top and a closed bottom and an interior surface. The plunger has an outer surface and a longitudinal passageway extending therethrough. The plunger further having an outlet valve mounted therein and an upper end and a lower end. The lower end being slidably disposed within the open top of the reservoir forming an interior chamber within the reservoir. The interior chamber has an annular chamber and a main chamber. The annular chamber being in fluid communication with the main chamber. The annular chamber is formed by the outer surface of the plunger being spaced away from the interior surface of the reservoir such that there is no frictional contact between the outer surface and the interior surface. The closure being attached to the open top of the reservoir allowing the plunger to slidably extend through the closure such that the interior chamber is sealingly closed. The nozzle is mounted on the upper end of the plunger such that the longitudinal passageway is in fluid communication with the nozzle. The interior chamber is separated from the longitudinal passageway by the outlet valve.

摘要： A pump and pump securing device, which pump securing device includes, at its axially-outer end, an axially-outer step and a axially-inner step. These steps are used to interact with a radially-projecting flange on the pump, thereby allowing the pump to be securely snapped into the mounting cup without the need for crimping. The steps also control the position of the pump relative to the mounting cup. As a result, the steps prevent the pump from compressing gaskets in the assembly, thereby controlling variations in pump dosage resulting from gasket compression. The flange can include slots creating vent paths for venting air into the container during operation of the pump.

摘要： A manually operated reciprocating fluid pump for securement to a container's mouth. The fluid pump comprises a disperser body, a closure cap, a seal assembly, and a priming check valve. The dispenser body has a pump mechanism, a discharge port, and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port. The closure cap is connected to the dispenser body and is configured for closing the mouth of the container. The seal assembly has a first portion and a second portion. The first portion is shaped and configured for preventing leakage between the closure cap and the mouth of the container when the closure cap closes the mouth of the container. The second portion has an intake port adapted for fluid communication with liquid contained in the container. The second portion of the seal assembly and the dispenser body define an intake liquid flow path providing fluid communication between the intake port and the pump mechanism. A check valve in the intake liquid flow path is configured for permitting fluid flow from the intake port to the pump mechanism and for checking fluid flow from the pump mechanism to the intake port. The second portion of the seal assembly comprises at least part of the check valve.

摘要： A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. An elastomeric pump element is positioned generally horizontally such that pulling the trigger retracts the element and releasing the trigger allows the element to extend. The sprayer includes a low cost spinner assembly and low cost valving to control the flow of liquid within the sprayer. In one aspect of the invention, the housing has front and rear sections with the rear section having a saddle portion and being hinged to the front section for pivotal movement from an open position for molding the housing to a closed position for operating the sprayer. In another aspect of the invention, the container has a rear portion which extends upwardly past the neck and defining a saddle recess, with the housing connected to the neck of the container and positioned forwardly of the upwardly extending container portion. The sprayer may include an elastomeric spring for biasing the pump element in the extended position.

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.
