Abstract
ABSTRACT OF THE DISCLOSURE
A vapourizing device, preferably made of plastic, for volatile sub-stances, more particularly air-fresheners, has a box-like lower part with a screw threaded cover. A substance-carrier is inserted into the container.
The cover rotates between limiting positions, closing the container sealingly in the one terminal position of rotation, whereas, in the other terminal position of rotation, the cover is raised from sealing surfaces in the lower part to expose openings in the casing which allow the volatile substances to escape. The lower part of the container is pot-shaped and has no openings;
the necessary openings being arranged in the casing of the cover. The edge-part of the mouth of the lower part of the container is in the form of a sealing surface facing the sealing surfaces arranged in the cover.

Description
3~
The invention relates to a vapourizing device, preferably made of plastic, for volatile substances, more particularly to air-fresheners.
A known device consists of a can-like lower container-part having a screw-cover and a substance-carrier lnserted into the said container. The screw-cover is rotatable between l;miting positions, closing the said con-taincr sealingly in one terminal position (wherein the edge-parts of the mouth of the one part of the container lie sealingly against matching sealing sur-faces on the other part thereof) whereas in the other terminal position of rotation, the cover is raised from the sealing surfaces and exposes openings in the casing which allow the volatile substances to escape.
In the case of a vapourizing device of this kind, disclosed in United States Patent 4,014,501, the edge-part of the mouth of the screw-cover forms a sealing surface which, when the container is closed, engages sealing-ly in a groove, arranged around the lower part of the container, in the vicinity of the bottom thereof.
Several relatively wide slots are provided in the casing of the lower part of the container, these slots bsing spaced from each other around the periphery, extending axially parallel, and being open towards the free end-face, the volatile substancesbeing able to escape through the slots when-ever the screw-cover is rotated into the open position. Brackets are moulded on the inside of the casing, between the slots in the lower part of the con-tainer. These brackets impart stiffness to the wall of the lower casing, but increase the amount of material required to fabricate the casing. The brackets support the substance-carrier to be placed in the lower part of the container in such a manner that the carrier is arranged facing the slots and at a dis-tance from the bottom of the container.
With this design, however, there is the danger of persons, especial-ly children, contacting the substance-carrier, and this may be harmful if ~;
3~
the substance contains toxic ingredlents, for example insecticides, since, when the screw-cover is in the open position, there is straight-line access to the substance-carrier through the relatively large slots in the lower part of the container.
~ lother disadvantage is that dust and/or condensates, carried by convection currents through the slots into the container may be deposited all over the surface of the substance-carrier, thus making the release of the substance at least more di~ficult.
; It is therefore the purpose of the invention to improve a vapouriz-ing device of the type described hereinbefore, which in operation, prevents unintentional contact with the substance-carrier, and reduce the amount of material used, while still providing a container having a gas-tight seal.
The invention provides a vapouri~ing device, for volatile substanc-es, said device comprising a container formed by a box-like lower part, an upper part comprising a cover in screw-threaded engagement with the lower part and a substance-carrier inserted into the container, said cover being rotat-able relative to said lower part between one terminal position, wherein co-operating sealing surfaces on the cover and on the lower part are engaged to seal the interior of the container, and a second terminal position wherein said sealing surfaces are spaced apart to expose the interior of the contain-er to atmosphere through openings in the container to allow the volatile sub-stance to escape, wherein:-a) the lower part of the container is pot-shaped and has a peripheral wall that is imperforate;
b) said openings are arranged in a peripheral wall of the cover; and c) said peripheral wall of the lower part of the container has an edge which forms one of said co-operating sealing surfaces and faces another , .
6~B
of said sealing surfaces arranged in thc cover.
The advantage of this is that the substance-carrier is now arrang-ed in the lower part of the con~ainer and is tllus protected against unwanted access and contamination.
Moreover, the hitherto necessary support brackets, which use up so much material, are now redundant, although ~he device is highly rigid and gas-tight.
An embodiment o the invention will now be described in greater detail, in conjunction with the drawings attached hereto, wherein:
Figure 1 is an exploded view of a vapourizing device as seen from the front.
Figure 2 is a front view of the device, but in the closed position and partly cut away;
Figure 3 is a view as in Figure 2, but in the open position;
Figure 4 is a plan view of the device.
This vapourizing device for volatile substances, intended more particularly for use in motor vehicles, comprises a pot-shaped lower contain-er-part 1, a screw-cover 2, and a substance-carrier 3 in the form of a cellu-lose plate~ removably positioned in the lower part 1 of the container.
The screw-cover 2, is mounted upon lower part 1 of the container and is adapted to rotate thereon within limits, and has a casing formed with several openings 4 distributed uniformly around the periphery of the cover.
Moreover, the mouth of lower part 1 of the container is in the form of a conically converging sealing surface 5 which, when the container is closed~ lies sealingly against a matching sealing surface 6 of a wall 7 moulded on the inside of screw-cover 2.
Openings 4 extend fror.l the end wall of the screw-cover 2, ~o that ~43~
when the cover is rotated into the open position, the openings are uncovered from the casing of lower part 1 of the container.
In order to limit the rotation of cover 2, stops, not shown, are moulded to the screw threads thereof, to co-operate with the thread in the lower part of the container. The screw thread is a four-skart thread.
Located on the back of lower part 1 of the container is an attachment-element comprising a plate 8, one side of which is detachably secured to lower part 1 of the container by a tongue-and-groove or plug connection, while the other side carries an adhesive coating.
