Abstract
An improved shower head dispenser for selectively dispensing and mixing liquid additives with shower water. The shower head dispenser comprises a body having a water inlet connected to a source of water under pressure and having an outlet. The body also defines an inlet chamber communicating with the inlet and a small diameter passage connects the inlet chamber with the outlet. One or more liquid additives are contained in separate bottles or containers and each container is connected through a supply line to a manually operated valve. The valve selectively connects each supply line with an aspirating conduit which communicates with the passage in the body. The body also includes a series of the larger outer passages which connect the inlet chamber and the outlet and are located around the first passage. The flow of water through the first passage creates an aspirating action to draw the liquid additive from the desired container and mix the additive with the water which is then dispensed through the outlet. The volume of water flow through the outer passages will vary with water pressure variations, while the volume of water flowing through the first passage will remain relatively…
