<p>A device for evaporating para-medical and cosmetic active substances is composed of a plate-like flat hollow body (1, 2) with two large side walls (1b, 1b'), of which at least one has a porous area, and a sliding covering element (5) movably arranged thereon. In order to seal the hollow body and prevent losses of active substances, the hollow body is provided with a continuous outwardly expanding, sealing channel (2b) open towards the covering element. In order to ensure the engagement of a marginal portion of the covering element with this sealing channel in the closing position, the marginal portion of the covering element is outwardly provided with a complementary tapering portion (5b) to the sealing channel. The outer surfaces of the hollow body are further formed at least in their marginal sections in the area of the sealing channel and of the inner surface of the covering element as smooth sealing surfaces that sealingly contact each other in the closing position. The device can be used for the active evaporation for example of para-medical active substances (as mouth and nose inhalator) as well as for the passive evaporation for example of perfume as a pocket perfume dispenser for clothes or as a plug-in gadget.</p> |
