Device and method for providing additives to a stream of water

Abstract

A device is mounted between an inlet pipe and a shower head and includes a receptacle for mixing a stream of water with additives. A portion of the stream of water passing from the inlet pipe to the shower head is diverted into the receptacle. The receptacle includes replaceable containers, a first container containing a first additive and a second container containing a second additive. The diverted stream of water mixes with the first additive and the second additive upon contact with the first and second containers. The diverted stream containing additives is then returned to the main stream of water which exits the shower head. The flow of the diverted water to and from the receptacle is controlled by a valve. The present invention provides an improvement over known arrangements by providing additives which are kept separate from one another preventing a chemical reaction between the additives which would cause a loss of potency.
