DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a device for long-term evaporation of liquid perfumes, for placing in the pockets of garments, in handbags and the like and equipped with a stand for use as a free standing evaporator. Within the said fields the invention concerns a device for long-term evaporation comprising a flat, plate-like basic member which encloses a perfume carrier and which has at least one wall made porous for evaporation purposes. The perfumes may equally be of a paramedicinal type, e.g. to act on the respiratory tracts.
STATE OF THE ART
Evaporators of the above type which have already been proposed in prior publications are accommodated in corsetry, bras, underarm pads and similar garments, which are provided with special pockets for the purpose. In one of these known constructions the container surrounding the perfume carrier is made of viscose sponge and contains a slot-like chamber into which is pushed a perfume capsule which is as shallow as a board and which has a capillary hole (Swiss Pat. No. 367945). The flexible container is surrounded by an elastic, perforated cover. Another proposal is for a perfume tablet of solid or semi-solid consistency to be accommodated directly in a bag provided with evaporation holes (Swiss Pat. No. 345432).
Because of their impractical construction and the arbitrary nature of their application these evaporators have never found acceptance.
DISCLOSURE OF INVENTION
The problem underlying the invention is to develop an evaporator of the above type so as to give it a novel form and construction, in which it is particularly convenient to manipulate, and so as to adapt it particularly for carrying in pockets which are provided in garments in any case, such as breast pockets of jackets, shirts and blouses, in inside jacket pockets and the like. A particularly large evaporation capacity must further be obtained, in addition, a simple appropriate development must provide for the evaporator to be used as a free-standing appliance.
The invention is characterised in that the basic member is provided with a second chamber which, in the form of a reserve scent chamber, communicates with the evaporation chamber by means of at least one channel for the passage of perfume, and in that a cover member, which is mounted on the basic member and movable thereon in the manner of a slide, can be transferred from a sealing position, in which the porous evaporation region is covered, to at least one evaporating position.
A further feature of the invention is that the cover member is in the form of a sheath-like sleeve which is provided with an inwardly directed engaging cam for the purpose of securing a plurality of adjustment positions, and that by virtue of the inherent resilience of the corresponding wall of the cover member, the engaging cam exerts a locking action in co-operation with a longitudinal row of evaporation openings in the basic member.
Wick-like perfume conductors are proposed to convey the liquid perfume from the reserve chamber into the evaporation chamber, the longitudinal portions of the conductors, which extend into the evaporation chamber, also acting as evaporating perfume carriers. Other features of the invention will emerge from the description of the drawings.
