Abstract:
A fluid-dispensing device which selectively draws fluid out from at least two containers or fluid chambers, mixes the fluids in a desired concentration or ratio and expels the mixture of fluids out a nozzle. The dispensing device may be equipped with a mechanism for variably controlling the ratio of the fluids being mixed. The containers may be bottles connectable to the fluid-dispensing device and selectively detachable for refilling with fluid or exchanging one of the containers with another container having an alternate fluid. The bottles include mating elements to permit interconnection of the bottles as well as venting and spill prevention mechanisms.
Abstract:
A spraying device comprising a spray tube having a fluid entrance end connectable to a primary fluid source, and a fluid exit end upon which an additive fluid dispenser is removably mounted. The additive fluid dispenser, having a chamber for holding additive fluid and a mixing chamber, is coupled to the fluid exit end of the spray tube in coaxial alignment with the direction of flow of primary fluid through the spray tube, causing opening of a valve mechanism in the fluid dispenser. The additive fluid then is metered into the primary fluid flowing through the dispenser, by diverting a portion of the primary fluid flow against a movable piston on a piston guide member-primary fluid conduit, to cause flow of the additive fluid through the valve mechanism. The spray tube may be of elongated telescoping construction, or of nontelescoping construction, and may include a control valve. The additive fluid dispenser preferably comes prefilled, is removably mounted on the spray tube by a quick-releasable connection, and is disposable.
Abstract:
A dispensing device or trigger sprayer which selectively draws fluid out from at least two containers, mixes the fluids in a desired concentration or ratio and expels the mixture of fluids out a nozzle. The trigger sprayer is equipped with a metering device for variably controlling the ratio of the fluids being mixed. The containers or bottles connected to the trigger sprayer are selectively detachable for refilling a container with fluid or exchanging one of the containers with another container having an alternate fluid.
Abstract:
A spraying device (10) includes a compound fourway rotatable control valve (30), an additive fluid control disc member (84) and a spray selector disc member (104), whereby a primary fluid, such as water, and an additive fluid, such as detergent, can be sprayed or dispensed in various spray patterns separately, or as a mixture having selectively variable concentrations of the additive fluid in the primary fluid. The compound fourway rotatable valve 30 is movable from an inoperative "OFF" position into first, second and third "WATER RINSE", "SOAP-AND-WATER" and "SUDS ONLY" operative positions. The control disc member (84) includes a plurality of orifices (86) of various diameters for controlling the amount of additive fluid dispensed into the primary fluid from a resilient bladder (16) containing the additive fluid as the bladder is collapsed in response to external pressure thereon by the primary fluid. The spray selector disc member (104) provides various spray patterns as the result of having orifices (112) of various configurations formed therethrough and selectively positionable in alignment with a discharge orifice of the device. A telescoping spray tube assembly (122), which telescopes outwardly in response to fluid pressure, may be utilized in place of the spray selector disc member (104).
