32,4 2 Claims. 01. 239-312 ABSTRACT OF THE DISCLOSURE One of the chief objects of the invention is to produce a practical shower assembly enabling the various operations of washing and rinsing to be carried out in a simple and speedy manner.

Another object of the invention is to arrange a cartridge 0n the shower appliance, capable of distributing some kind of product in the circuit in question, in one of the circuits of the shower appliance mixing with the liquid in movement.

Another object of the invention is to enable the alternative distribution of a product contained in the cartridge in communication with one of the Water circuits of the shower appliance, said product being able to serve for all treatments, especially products for shampooing, for treating the scalp, treating the skin, industrial cleaning or the like.

Other objects and advantages will be revealed by the description hereafter and the attached drawings, in which:

FIGURE 13 is a sectional elevation view of the plug of the cartridge,

FIGURE 14 is a View on top of the plug of FIG- URE 13.

The shower appliance shown in the attached figures, possesses two water circuits independent of each other, a dosing cartridge 2 being connected by screwing on to the rose of the shower 1.

The shower rose comprises, in the longitudinal direction, a central water inlet 3 ending at a chamber 4, in

which are two identical valves 5 and 6. Pressure on the valve 5 enables clean water to flow through a duct 7 to the annular part of the rose drilled with holes 8; pressure on the valve 6 enables clean water to flow through a duct 9 and to reach the cartridge 2.

Each valve 4 (FIGURES 4 to 7) consists of a rod 5 with threaded head and lower end. A fluid-tight Washer 5 is placed under the rod and held by a support washer 5 The cartridge 2 is provided internally with a rigid tube 10 placed in the extension of the threaded spout 16 and through which the Water penetrates and thrusts the product contained in said cartridge towards the exterior.

Apertures 11 are provided on the lower face of the cartridge 2 to enable the discharge of the water and cleaning product mixture.

This mixture passes into the shower appliance, in a part 13 provided for this purpose, axially to the outlet face of the spraying rose.

The part 13 is provided at its lower end with two grids 14, for powdering and making the output of the product more homogeneous.

The efiiciency of rinsing and the evacuation of the product contained in the dosing cartridge, is a function of the diameter and length of the tube 10; the tube 10 can also be perforated on the walls when a certain dilution of the product is required.

It is quite obvious that the dosing cartridges can contain either a liquid, granules or products of all kinds.

Also, it is possible to provide dosing cartridges in which case they are filled with various perfumery products, soap, cleaning products, articles for various treatments, etc.

The interest of the invention also lies in the interchangeability of the dosing cartridges Which can, of course, with a variable quantity of the product utilized, be employed either solely or not, and changed after service.

The dosing cartridge can obviously be adapted to professional sanitary appliances as well as on appliances at the disposal of private individuals in their bathrooms.

What we claim is:

1. Shower apparatus which is specifically adapted for washing hair comprising a spraying head having at least two flow paths in the apparatus independent of each other, a cartridge removably coupled to and carried externally by the apparatus, said cartridge being opposite the spraying head and containing a product to be selectively dispensed through said spraying head, means for selectively interconnecting at least one of said flow paths with said removable cartridge so that said one of said paths dispenses some of the product contained in said cartridge through said head.

2. Shower apparatus as set forth in claim 1 including a tube provided inside said removable cartridge for conveying liquid from an inlet in said cartridge into an area of the cartridge remote from the head to thus cause the discharge of a product contained within the cartridge through an outlet in said cartridge to said head, said cartridge having its outlet and inlet at one end thereof.
