Abstract: A hose end sprayer has a sprayer lid and a container. The sprayer lid has a cap with a pair of bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the sprayer lid's cap. The connectors and a threaded adapter allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end, with a siphon tube intersecting the conduit within the periphery of the smaller of the bottle connectors, with mixture of pressurized carrier water entering the liquid conduit at the hose inlet with liquid chemical siphoned from the container through the siphon tube. The chemical/water admixture is expelled from the spray nozzle.

Abstract: A manually pressurizable house and garden tank sprayer employing a separate diluent tank and liquid chemical concentrate container, wherein the concentrate container is mounted to and carried by the diluent container or by a spray wand. The tank containing diluent is pressurized by a conventional hand pump, and the same hand pump pressure pressurizes the concentrate container. The diluent and concentrate chemical are not admixed until just before the liquids are dispensed, so that unused chemicals are not contaminated or diluted until they are used.

Abstract: A hose end sprayer comprising a sprayer lid and container includes multiple bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the cap of the sprayer lid. The connectors allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end. A siphon tube intersects the conduit within the periphery of the smallest of the bottle connectors. The siphon tube carries liquid chemical from a container connected to the sprayer lid, such as a bottle of concentrated liquid, into the liquid conduit, where the liquid mixes with carrier water entering the liquid conduit at line pressure from an external hose connected to the hose inlet. The liquid carrier water mixture is then expelled from the nozzle.

Abstract: An applicator system comprises a reservoir, a conduit extending from a first end at the reservoir to an opposite terminal end, an applicator connected with the conduit, a flow control engaging the conduit, and a holder releasably coupling with the applicator. The applicator has a liquid impermeable back, an opposite porous face, and a plenum. The plenum, situated between the back and face, releasably couples with the conduit terminal end and distributes fluid to the face. The face and plenum may be replaceable and disposable. The holder is a rigid member that releasably couples with the applicator, provides a structural foundation to the applicator, and includes a handle for manipulation by a user. An extension can be employed to connect the flow control to the handle, effectively extending the length of the handle. A helical coil portion of the conduit can be conveniently wrapped around the extension to prevent kinking.

Abstract: A portable sprayer which has a resealable closure, a dispensing valve and a pressure-responsive filling valve attached to a receptacle. As the receptacle is filled with fluid through the valve, air which is entrapped in the receptacle pressurizes the container to facilitate dispensing the fluid. During filling, the inlet valve closes if the pressure of the liquid source to which the sprayer is connected exceeds that within the container by a predetermined amount. The inlet valve also closes when the filling hose is disconnected from the container in order to close the container.

Abstract: A portable sprayer which has a resealable closure, a dispensing valve and a quick disconnect one-way valve attached to a receptacle. As the receptacle is filled with fluid through the one-way valve, air which is entrapped in the receptacle pressurizes the container to facilitate dispensing the fluid. By locking the dispensing valve open or by opening the top closure of the sprayer, and securing a hose to the quick disconnect one-way valve, one can flush the sprayer out by allowing fresh water to flow continually through the system.
