Furthermore, in the jacket of the lower part of the container there are several, in the jacket of the screw cap 2, which is screwed on the container and is spaced apart from one another to a limited extent on the circumference, there are several, axially parallel, open to the free end face on the circumference Evenly distributed openings 4 are provided, relatively wide slots through which volatile arranges.

The openings 4 begin at the bottom of the screw cap 2, so that the openings 4 are released from the jacket of the lower container part 1 when the screw cover 2 is turned into the open position.

To limit the rotation of the lid 2, not shown stops are formed on its threads, which correspond to the threads of the lower part of the container. The thread is designed as a four-start thread. On the back of the lower part 1 of the container, a fastening element is provided, in the form that a fastening plate 8 is provided which, on the one hand, is releasably connected to the lower part 1 of the container by means of a tongue and groove type connector and carries an adhesive layer on its rear side.

All new individual and combination features disclosed in the description and / or drawing are regarded as essential to the invention.

Claims (4)

646108 1. Evaporation device made of plastic for volatile hen and serve as supports for the active substances to be fixed in the container lower part, in particular fragrances, consisting of a clamping active substance carrier, so that the latter with container with a can-like container lower part, with a distance from the lower part bottom and the slots opposite a screw cap as the upper container part and one in FIG. 5 is arranged. Containers inserted fragrance carrier, the limited resulting from this, however, is the risk of touching the rotatable screw cap in one end position of the active ingredient carrier, especially by children's hands, which therefore closes more tightly, and the rim parts of the mouth can be harmful if the fragrances are more or less Part of the container on the sealing surfaces corresponding to the latter has poisonous active substances, for example insecticide associated with the other part of the container, should be tightly closed, because the active substance carrier in the open position and in the other rotary end position with the screw cap standing by the sealing surface due to the relatively large size Slits chen lifted lid releases breakthroughs, through which the volatile lower part of the container can be reached straight. Allowing active substances to escape, characterized by This has the disadvantage, however, that convection currents passed through the slots: a.) The lower container part (1) is formed as a breakthrough-free, pot-guided dust and / or condensate on the entire miger container; Put down the surface of the drug carrier and thereby the b.) The openings (4) in the jacket of the screw cap can at least make drug delivery difficult. 2. Evaporation device according to claim 1, characterized sern, wherein also a gas-tight sealability of the pre-characterized that should be given on the inner end face of the screw direction. cover (2) a molded on to the mouth of the The solution to this problem is characterized by the following Bottom part of the container (1) tightly fitting socket 25 features: (7) is arranged. a.) the lower part of the container is a breakthrough-free, pot-shaped (2) arranged and the object of the invention is now to provide an evaporation c.) The mouth edge part of the lower container part (1) is designed as a direction of the type described above with regard to its radio sealing surface, the 20 tion arranged in the cover (2), its safety against unintentional contact with the sealing surfaces. Drug carrier and its material requirements to improve 2nd PATENT CLAIMS first of all provide sufficient shape stiffness 3. evaporation device according to claim 2, characterized ger container formed, characterized that the nozzle (7) in the mouth of the Be.) the openings are in the jacket of the screw cap the lower part of the container (1) is designed to be tight and engaging. 30 c.) The mouth edge part of the lower container part is as 4. Evaporation device according to claim 2 or 3, formed as a sealing surface, which is arranged in the cover, characterized in that on the connecting piece (7) and on the Mün sealing surfaces face each other. Formation of the container lower part tapered sealing surface. This has the advantages that now the active substance carrier Chen (5, 6) are arranged. in the lower part of the container against access and contamination 3s is arranged protected. The previously required, elaborate support brackets. However, this also ensures a high degree of dimensional stability of the device and gas tightness of the device.
