摘要： The present invention pertains to a trigger sprayer which is connectable to two container volumes containing separate liquids. The sprayer has a trigger that is manipulated to draw the separate liquids into two separate pump chambers and then supply the two separate liquids from the pump chambers to a discharge passage of the sprayer. In the discharge passage the two separate liquids are mixed together prior to their being dispensed from the discharge passage as a spray.

摘要： A dual fluid dispenser comprising a dispenser body and a nozzle. The dispenser body has first and second pump chambers, a first intake port adapted for fluid communication with a first liquid source, a second intake port adapted for fluid communication with a second with a first liquid source, a second intake port adapted for fluid communication with a second liquid source, first and second intake liquid flow paths for passage of fluid from the intake ports to the pump chambers, and first and second discharge liquid passageways. A third discharge liquid passageway is defined at least in part by the dispenser body. The third discharge liquid passageway includes a mixing chamber and a spinner chamber downstream of the mixing chamber. The first and second discharge liquid passageways are configured for passage of liquid from the first and second pump chambers to the mixing chamber. The nozzle includes a nozzle orifice in fluid communication with the spinner chamber. A fluid spinner member is in the spinner chamber. The pump chambers, and intake liquid flow paths are configured so that varying the volume of the pump chambers draws liquid from the intake liquid flow paths, forces the drawn liquids from the pump chambers to the mixing chambers where the liquids are mixed, and forces the mixed liquids through the spinner chamber and out the nozzle orifice.

摘要： A liquid dispenser comprises a dispenser body and a flow restrictor. The dispenser body has a pump mechanism, an intake port adapted for fluid communication with a source of liquid, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port. The flow restrictor is in the discharge liquid flow path and is moveable between first and second positions. The flow restrictor is configured for permitting fluid flow from the pump mechanism to the discharge port when the flow restrictor is in its first position, and is configured for at least partially impeding fluid flow from the pump mechanism to the discharge port when the flow restrictor is in its second position.

摘要： A closure is removably attachable to a container and comprises a dispensing orifice and a tubular valve element that is biased closed blocking communication of the container with the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens communication with the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.

摘要： 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.
