Description

The invention relates to an evaporation device, in particular made of plastic, for insecticides and / or other volatile active ingredients, consisting of a housing having openings in which the Active substances enclosed by a gas-tight envelope are arranged, the active substances being cut through the shell can be released in a contactless manner by an opener formed on the housing, wherein furthermore, the opener is shielded from the housing having a lower part and an upper part, also in the Housing a carrier which absorbs the active substances emerging from the opened cover and extends to the openings in the housing facing active ingredient evaporation surfaces is arranged, and wherein the active ingredient shell are arranged in one housing part and the opener in the other housing part.

An evaporation device of this type is known from the German patent application 28 07 424.

Here, the housing is assembled from two prefabricated housing parts.

It is also known from the above German interpretation for refilling the device with active ingredient that insert a gas-tight active substance envelope into a third, prefabricated container open at the bottom and this container to plug into the device housing interchangeably.

The manufacture of those device parts and the assembly of the latter are, however, relatively cumbersome and time consuming.

Furthermore, DE-GB 19 97138 discloses an evaporation device for insecticides known, wherein a plate soaked with insecticide from a window-like breakthroughs comprising housing made of plastic and wherein a part of the housing front side for inserting the impregnated plate is hinged by means of a film hinge and designed to be folded forward.

This housing also requires a relatively complicated and expensive form of manufacture.

In addition, refilling of the device with poisonous insecticide is not provided here and not to be recommended, because you will come into direct contact with the poisonous insecticide could come.

The object of the invention is now to provide an evaporation device in the preamble of Claim 1 specified type to improve that while maintaining the prior art Advantages already achieved in addition to a simplification of the manufacture of the device parts as well as their assembly can be achieved, which allows a simple and cheaper, machine manufacturing option.

The solution to this problem is that the housing parts are arranged side by side and by means of an integrally formed film hinge connected to one another and manufactured in one piece with their mouths directed to one another around the film hinge axis are designed to be foldable and latchable with one another are and that the casing containing the active ingredient and the opener each next to the film hinge axis so are arranged that when the housing parts are folded onto one another, the opener is inserted into the active substance sleeve opening engages.

With these measures it is now not only

possible to have all housing parts together in a single one

ίο Production process by primary molding, whereby preferably the mouths of the housing parts both with respect to one another and with respect to the plane of division of the mold Should be arranged at the same level, but in addition, this design allows a simple machine addition of the active ingredient shell and the carrier absorbing the active ingredients.

In addition, this evaporation device can be easily and safely used by the purchaser, and only to be put into operation by opening the housing parts.

Finally, it is just as easy to exchange the active ingredient shell.

In order to make contact with the possibly toxic active ingredients, especially with the To make it even more difficult to replace an active ingredient cover than before, it is advantageous if the upper part of the housing is divided into two parts, both upper housing sections independently of one another with their mouths on the mouth of the lower part of the housing can be supported, the latter can be folded over together to completely cover and with the lower part of the housing are designed to be latched and that on the one first upper housing section the active ingredient cover is exchangeably retained, while the other, second, upper housing section having the housing openings the largest part of the carrier which is arranged in the lower part of the housing and absorbs the active substance covers.
