Abstract: A sequential delivery valve provides sequential delivery of gas propellant and liquid product from a container to a dispensing head for ejecting an atomized spray from the dispensing head. When the dispensing head is depressed, a pusher in the valve passes from a closed position wherein no liquid and no gas is allowed to travel through the valve to a partially open position where only gas is allowed to travel through the valve and eventually to a fully open position wherein both gas and liquid are allowed to travel through the valve into the dispensing head. When the dispensing head is released, the pusher passes from the fully open position back to a partially open position allowing only gas to travel through the valve and eventually to the closed position wherein no gas and no liquid are allowed to travel through the valve into the dispensing head.

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.

Abstract: An improved hose end sprayer is provided in which chemical concentrate from a reservoir circumscribing a tube secured to the end of the hose is gradually fed into a liquid stream passing through the tube. A back pressure baffle is fitted within the tube between a pair of holes spaced in the tube in the portion thereof circumscribed by the reservoir walls. A first of the holes permits gradually release of liquid concentrate within the reservoir when under pressure into the tube. This hole is positioned downstream of the baffle. A partition within the chamber is fitted over the tube, at least a portion thereof being movable under pressure from liquid within the tube passing through the second hole upstream of the baffle into the reservoir. This action causes sufficient pressure on the concentrate to cause its gradual release through the first hole into the tube.
