Abstract: A valve system for a trigger sprayer including a valve forming an air spring with a portion of the trigger sprayer and being made of a flexible or elastomeric material. The trigger sprayer may include an air-spring valve system wherein the air-spring valve system provides precompression during a pump stroke.

Abstract: A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. A bimodal distribution of particle sizes is obtained under two different operating conditions. The sprayer/liquid combination according to the present invention compresses the difference between the two modes, without requiring undue work by the operator. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.

Abstract: A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The sprayer is suitable for dispensing liquid from a reservoir, through a nozzle into particles. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. The trigger sprayer advantageously delivers a particle size distribution suitable for liquids having particular rheological properties. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.

Abstract: A fluid dispenser pump has a fluid reservoir, and a pump that has a pump chamber with a piston that moves within the pump chamber to pump fluids out a dispensing orifice. The pump has a priming air channel that fluidly connects the reservoir to the pump chamber and is separate from the fluid channel that connects the reservoir to the pump chamber. With non-sterile fluids, such as medicine, the air channel cannot displace the air to the exterior of the dispenser, but must displace it to the reservoir where it assists in priming the fluid channel.

Abstract: A foam dispensing device uses a single actuator to actuate two concentric pistons, one for an air chamber and one for a telescopically oriented liquid chamber. In all of the various embodiments the liquid chamber stops its actuation first and can continue to move along with the single actuator and the air chamber continues to dispense air. The air and liquids are dispensed into foaming chamber and then dispensed. The liquid chamber can continue to move because the liquid chamber is attached to the pump system by a deformable connector or some form. This arrangement allows for a foaming device that uses just one actuator that has the ability to dispense foam in the first phase and just air to clear out the nozzle effectively in the second phase.

Abstract: A rolling liquid herbicide applicator with an adjustable shield is attached to a hollow pole having an adjustable width protective shield mounted to one end weighted, textured wheels for rolling over most terrains are attached to the adjustable width protective shield. On the opposite end of the hollow pole handle is a trigger. When the trigger is activated, an internal trigger stick is moved down through the hollow pole, thereby causing a “C” shaped piece to move upward. This upward movement pushes on a hard flat disk. The movement of the hard flat disk causes pliable cap center to move. The gravity flow of liquid herbicide from a liquid herbicide container causes the liquid herbicide to move through a tube and nozzle assembly. The adjustable width protective shield over the nozzle prevents overspray and accidental contact of the liquid herbicide on healthy desired vegetation.
