ABSTRACT OF THE DISCLOSURE 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. This relatively simple construction enables concentrate from the reservoir to be passed into the stream of liquid while the partition minimizes dilution of the concentrate in the reservoir by liquid from the tube, a problem often found in prior are hose end sprayers of this general type.
