ment of the mouth and an appliance for conc veying the rinsing liquid to the mouth.

Into a container capable of being closed water and chemicals are introduced, which evolve gases when mixed. The vessel is thereupon closed and the gas is evolved, impregnates the rinsing liquid and forces it through a tube into the mouth rinsing appliance. The flow is suitably regulated by means of a valve. The chemicals preferably used are solid, organic acids (such as' tartaric acid or citric acid) and. alkali bicarbonates, by the mixture of the aqueous solutions of which carbonic acid is developed, which is particularly suitable both as a driving agent and on account of its disinfecting ,and tooth-stone solving action for the treatment of the mouth and teeth. With these chemicals which may suitably be used inthe form of com ressed tablets essential oils, such as oil of peppermint or oil of cloves,

- and other mouth disinfectants, such as thymol or chlorat'el of potash, may be mixed, so that the rinsing liquid is not only impregnated with gas by the addition of chemlcals, but also assumes the properties of a mouth- Wash.

The container, into which the rinsing liquid and the chemicals are introduced, is provided with a tube for the gas-impregnated rinsing water, leading to th'e mouth rinsing appliance which may be of any suitable construction. The container in which the impregnating and pressure gas is evolved may be so constructed as to form the handle of a tooth brush.

Mouth rinsing appliances are known, in which the gas under pressure is taken from a vessel containing compressed carbonic acid. An appliance of this kind iscostlyl and inconvenient, it is also not suitable for use for instance as a travelling appliance.v No more can such tooth brushes be compared with the simple appliance according to the invention as have the rinsing liquid pum ed to them by hand. As air is used or t 's purpose, the particularly favourable eii'ect is not realized at all, which can be effected with the carbonic acid, in the ynascent state or in certain cases with purel oxygen.

In the accompanying drawing various constructional examples of the invention are shown partly in elevation and partly or entlrely in section. l

Fig. 1 showing the container inverted and supported by a bracket, Fig. 2 being in the main, an elevation of the apparatus, standing upright, and Fig. 3 being a section of a modification with brush attachment.

In Fig. 1 the liquid container l is held in .the support 8 which is fixed to the wall and is provided with a longitudinal slot for enabling the container to be inserted. Through the tube 3 the liquid container 1 is connected to the handle 4 of' the brush and to the cleanlng member 5 through the valve 6.

The filling opening of the Icontainer 1 is closed by the mechanism 2, into which the chemicals are introduced in the form of a tablet 7.

Theappliance is used in the following manner. The container 1 with the filling openlng at the top is filled with rinsing liquid. With the container still held in the same position the closing mechanism 2, into whlch the chemical tablet consisting for instance of a mixture of sodium bicarbonate with tartarc acid has been introduced, is screwed in. The container is thereupon inverted, the rinsing liquid comes in contact with the chemicals and the gas commences to evolve. Before the appliance is used the rinsing liquid may, if necessary, be warmed up to the desired temperature by meansI of the electric heatin resistance 9 in the container support 8 w ich is 'supplied with current through the leads 10. The cleaning member 5 is used in the ordinary manner, rinsing liquid being supplied to itv as required by actuating the valve 6.

It has been found, that the public are a t completely or almost -completely to iill t e container for holding the rinsing liquid and the gas' evolving chemicals, so that insufficient room remains for the gas evolved.

This is the cause of the danger of the con-l tainer bursting and also has the effect of reducing the `driving action of the gas, as under the very high pressure it dissolves to too great an extent in the rinsing liquid.

For overcomin this drawback the container (see Fig. 2 is provided with a separate vessel which, when the liquid is poured in, does not become filled with water and can therefore act as a gas chamber. The gas chamber may suitably be placed between the container for the rinsing liquid and the outlet valve. This separate chamber may be rovided with ridges or projections or other` devices for holding the chemicals in position, which are introduced in a solid state.

When the chemicalsare first placed in this separate vessel, they only come in Contact with the liquid at the moment in which the pressure vessel has already been closed again, so that no gas will be lost by being prematurely evolved and the person using the appliance will not be perturbed by the evolution of the gas starting beforehand.

The outlet branch for the liquid under pressure may be connected in a known inanner by a cap nut with the interchan 'cable rinsing members, such as nozzles, douc es or spraying members provided wit-lr tooth brushes. In the arrangement shown in Figure 2 the cap nut is provided with a longitudinal slot for the introduction of the various spraying members, without the necessity of completely removing the cap nut from the branch. This prevents the nut being lost and facilitates the attachment of the various sprayin members.

The liquid container 1 is provided at the top with the filling nozzle 2 having an internal thread. At the bottom of-the separate vessel 3 which serves the purpose of a gas chamber is a nozzle 4 havingan external thread which can be screwed into the internal thread of the filling nozzle 2, the rubber washer' acting asa gas tight packing. At the top of the vessel 3 is an opening having an internal thread 6. In this opening is soldered the plate 7 carrying the delivery tube 8. The top opening of the gas chamber 3 is closed by the valve part 9 the threaded part 11 of which is screwed into the internal thread in the top of the chamber 3. A gastight closure is ensured by the rubber gasket 10 which is pressed onto the top of the gas chamber, when the parts are screwed together. By depressing the conical valve 12 by means of the knob 13 the flexible tube 15 which acts as the valve packing is lifted from the valve seating 14, the passage 17 thus being opened so as to allow the liquid to flow to the branch 18. T he flexible tube 15 which is thrown over the top is held in position on the valve casing by the cap 1G so as to be fluid-tight. The branch 18 endsin the threaded part 19. rIhis part is bored out conically at 20. The cap nut 21 engages with the thread on the part 19. By means of the cap nut 21 the nozzle 22 for the iieX- ible tube 26, which terminates in a cone 23 at the end facing the branch 18, is pressed by means of the shoulders 24 in a fluid-tight manner into the conical part 20 of the branch 18, when the cap nut is tightened.

The connecting part 22 is connected by the flexible tube 26 to the spraying nozzle 27. For inserting the connecting part 22 or the sprayinflr members themselves the cap nut is provided with a slot 25 the shape of' which is shown in the section on line A-B and in the section on line C-D.

This appliance which, in contradistinction to that shown in Figure l, is held upright in the hand when in use, is operated in the following manner: The liquid container 1 is filled to the top with rinsing liquid. After the chemicals which are required for producing the gas and are preferably in tablet form have been introduced into the inverted gas chamber 3, into which the valve part has already been screwed, the whole arrangement is screwed into the container 1. By shaking or turning the a pliance over the chemical tablets are intio uced into the water in the vessel 1. The gas commences to evolve and, by depressing the conical valve 12, the gas impregnated rinsing liquid is caused to pass through the tube 8 and the passage 17 into the outlet nozzle 18 and into the rinsing member.

In the constructional form shown in Figure 3 about 100 Cc. of rinsing liquid are introduced into the container 1 which also serves as the handle of a brush. T he container is closed by the closing member 8 which is so constructed as to hold the ehemical cartridge 9. For ensuring as complete a delivery of' liquid as possible in the various positions, in which the brush is likely to be held, the rinsing water is taken from the container 1 by means of a iiexible tube 6 weighted by a weight 7 and is conveyed to the part 2 of the brush, which carries the cleaning member 3. The weight 7 will always force the end of the flexible tube downwards, so that, when cleaning the teeth, the liquid container will always be almost completely emptied. A. valve 5 is provided for regulating the How of the cleaning member. The ducts in the interior oi' the part 2 for conveying the liquid to the cleaning member are marked 4.

Vith its filling opening placed upwards the vessel 1 is filled with the rinsing liquid and, while still in the same position, is closed by means of the closing mechanism 8 containing the chemical cartridge. When the brush is turned over, so that the cartridge comes in contact with the liquid, the gas commences to evolve and the apparatus is ready for use. In this form oi' the appliance as well the rinsing liquid can be warmed in a similar holder to that provided for the liquid container in Fig. 1 directly in the brush.

With all the forms of the appliance other suitable devices besides tooth brushes can be inserted, such as douches for the treatment of the pharynx or mouth, the nose or ears and the like.
