Abstract
Abstract A device adapted to be operated in conjunction with a shower fixture for selectively dispensing one or a plurality of liquids into the water stream discharged by the shower nozzle. The device has a plurality of containers, each adapted to store a quantity of liquid, such as, but not limited to, a perfume, a soap, a detergent, a deodorant, an antiseptic, or other chemical substances desired by the user of the shower. Each container has a valve which is manually operated by the user to selectively dispense a predetermined amount of one or more of the liquids from their associated containers to the water stream. The containers are preferably constructed of a transparent material, such as transparent plastic, to permit the user of the shower to visually determine the amount of the liquid remaining within each container. In one example of the invention, an even number of containers are mounted on a support member which, in turn, is carried by the shower fixture. Each of half of the containers is filled with a different liquid, such as for example, soap, oil and a perfume, while each of the remaining half of the containers duplicates the contents of each of the first containers, so that the user may, by manually operating one of the valves, dispense a defined amount of the desired liquid into the water stream and, if the user desires to double that quantity, the valve of the second container containing the same liquid may be simultaneously operated to dispense twice the quantity of the liquid.

Independent Claim
327 words
A device for selectively dispensing a plurality of additive liquids into a main liquid supply line, said device comprising a housing separated into a plurality of compartments, each of said compartments being adapted to store one of said liquids and having liquid conducting means associated therewith for supplying the liquid stored therewithin to said main liquid supply line; and independently operative valve means for each of said compartments for controllably establishing a communication between said compartment and said main liquid supply line, said valve means comprising a tubular member having a piston slidably mounted therein for forming a chamber communicating with said compartment, a port extending through the wall of said tubular member, said port connecting said liquid conducting means to said chamber, means biasing said piston to a position closing said port to prevent communication between said chamber and said liquid conducting means, and control means for slidably displacing said piston to a position opening said port and placing said chamber in communication with said liquid conducting means, said control means comprising a rod attAched to one side of said piston and projecting beyond an end of said tubular member for manually pulling said piston to said second mentioned position, said valve means further comprising one-way valve means disposed between said chamber and said compartment for normally permitting communication between the interior of said compartment and said chamber and preventing return flow from said chamber to said compartment, such that said piston displaces liquid from the interior of said compartment into said chamber when the volume of said chamber is increased by movement of said piston and said piston displaces liquid from said chamber into said liquid conducting means to said main liquid supply line when said piston is moved by said biasing means to decrease the volume of said chamber, and second one-way valve means associated with said liquid conducting means for preventing a reverse flow from said main liquid supply line to said chamber.
