The BrflndMng concerns a device with the application of an active substance, in particular a coloring agent or something else Cosmetic means or the like on the hair of the head, with one designed as a handle, elastically deformable Receiving container, which carries a working head with at least one outlet opening for the outlet of the Active ingredient is provided, the receiving container at its container base facing away from the working head suppressed air intake valve opening in the receiving container having·

From the DB-GM 79 30 382 a hair coloring device is this Kind of known · The working head of this device includes in one unit what is required for coloring the hair Tools, namely a flaoh brush, a dome-like hair spreader, and a comb. These tools are functional arranged on the working head, which forms a paint container Torsehlieeendes Versehlu0tell.

In the case of the known device, a simple squeeze container is used as the paint container, i.e. a hand-held elastic container * Plastic container is used, with which the dye can be expressed by exerting pressure in the usual amount leaves. In this case, a ventilation valve or an air intake valve is provided, which in the elastic Rttok-

Check valve “Such valves require a relatively high manufacturing and assembly effort. ton of the hair dye are getischt into the container nuts, it 1st practically unavoidable ₉ Dafi including shaking of the ink container colorant from the valve dropwise and verursaoht hä6-liohe impurities. In addition, over time, the coloring agent builds up on the functional components of the ball valve, which makes it leaky.

The object of the invention is primarily to design a hand-held device of the type mentioned, which is preferably used as a hair dye device and is provided with a working head according to dom DS-GM 79 30 3 · 2, so that there is a j () in the production and assembly simple and inexpensive valve structure and valve arrangement that are adapted to the intended use of the device and that are absolutely functionally reliable and shake-free and, if necessary, easy to clean, even over a longer period of time

This object is achieved according to the invention in that the Air suction valve arranged on a closure piece made of plastic which closes the receptacle at its open foot end and is legibly arranged on the receptacle is that ah its side facing the receptacle a molded enclosure with an arranged therein, at least one rubber elastic covering the valve opening

In the case of the device, the air intake valve is therefore part of a package, which is preferably designed as a screw cap and then all squeeze-type receptacles designed as plastic receptacles are rare attach and το »this abnekmaa, ia sB« to rake the valve under running water and / or remove the elastic valve * »• ehlieS member, if« it has become brittle after a lesser brewing time drive through a few simple steps quickly * When removed Versehlufistüek the valve is more or less aufien free, which la regard to dl "good cleaning Tung possibility of valves whereby the Behälterreiniguag is boguastlgt is advantageous · Wr daa AufnahmebehMlter can one open the FuS Behilter be rerwendet · The proposition Bsteek old the valve seat can be produced inexpensively as oiafaohos plastic injection molded part. A simple, small, inexpensive and easy-to-clean valve housing made of rubber or rubber-like plastic is used as the closing element, and the door pull shaft was a flat, rounded shaft. The valve seat fliohe consists of an aa bed of the edging with a flat, annular rib or the like "which closes at least one valve opening or, alternatively, several valve openings located close to one another on the UB".

It has been shown * that old such a valve design requires ventilation that is as simple as it is functionally reliable.
