IPC: B01J4/00
Filed: 1975-06-30
Abstract: Dispenser is for adding controlled vols. of a liq. (esp. scented foam soln.) to flowing water, esp. for domestic showers. The dispenser has a component which is connected on one side to the water supply and on the other to the pipe at hose leading to the shower head. Water flowing through the component is accelerated through a construction to a slightly reduced pressure in the construction. According to the novelty, an adapter is connected at one end to a container for the liq., and is capable of being screwed vertically into component. At the other end, the adaptor has one or more openings, below which a valve seat is located. The valve seat is formed by the surfaces of the end of adaptor and component respectively. The adaptor has an internal passage extending from one end to the other. The space above the valve seat communicates with the water stream in construction through a slot whose cross-section increases towards construction. The opening between space and construction can be varied according to the depth to which adaptor is screwed into the vertical leg of component. There is no loss of additive when bottle is inverted and screwed into adaptor as the bottle can have a sealed top which is pierced by a spike. The arrangement ensures that the entire contents of the bottle are used up. Stepless, fine control of very small additive flow rates can be achieved.
