Shower head fluid dispenser

Claim 1

An improved, portable shower head fluid dispenser for shower stalls and tub areas of the type including a shower spray nozzle disposed on the end of a fluid dispenser valve block removably coupled to a water supply pipe wherein select fluid such as soap is passed through the valve block in selected quantities to mix with the shower water at the selection of a person in the shower, wherein the improvement comprises a removable valve block having a flow channel formed therethrough with a lower portion of greater diameter than an upper portion and provided for passage of shower water therethrough, said valve block having a depending communication passage formed generally orthogonal to said flow channel and communicating with said flow channel in the area of the interface between said lower and upper portions wherein a selectable venturi draft will be imparted to said depending communication passage and wherein said valve block includes a venting channel extending outwardly from the flow channel, a stationary vent block having an aperture therethrough adapted to communicate with said venting channel, and a slide block having a plurality of apertures of varying diameter formed therethrough, said slide block mounted for rectiliner movement parallel to said flow channel and vented to the atmosphere for select communication with said flow channel and selective control of said venturi draft, by varying the restrictions in said venting channel a fluid supply reservoir housing portably suspended beneath said shower head and supporting at least one fluid container, said housing including means for permitting visual observation of the fluid level in the container received therein and each container being connected in flow communication with said valve block through tubular members supplying the fluid to said valve block for discharge therefrom, said tubular members being in communication with said depending passage and one of said containers wherein a venturi draft will precipitate fluid flow therebetween, and a selector valve comprised of a ported shaft having apertures formed therethrough for opening, closing and channeling fluid flow therein, said shaft having a plurality of detent areas for rotational positioning in proper open and closed registration facilitating fluid flow operation in a shower stall area, said valve also including a selector dial of substantially enlarged surface area for facilitating valve selection by a person having wet hands and limited vision in the shower, and said valve being disposed between said valve block and said fluid supply housing and in communication with said tubular members between said valve block and said fluid supply housing for channeling the select fluid flow therebetween in response to said valve block.
