Abstract: A container for a volatile liquid in a liquid dispensing device comprises a body and a neck extending from the body to define an opening. A retention structure is integral with the container body and is adapted to be releasably engaged with two opposing sidewalls of a housing of the dispensing device. The sidewalls are spaced apart in a first direction, and the retention structure is inhibits motion of the container in two opposing directions generally transverse to the first direction. The retention structure may be located on a side of the container body. A capillary member extends from inside the container to an exterior of the container. The volatile liquid migrates along the capillary member from the reservoir to the exterior of the container where it is evaporated from the surface of the capillary member by forced airflow generated by a motorized fan mounted in the housing.

Abstract: An apparatus adapted to both purify an air flow passing through it and disseminate a volatile liquid therein, comprising a source of volatile liquid, a disseminating element for the liquid and a catalyst adapted to remove pollutants at relatively low temperatures, the aforementioned elements being arranged such that the air flow encounters first the catalyst and then the disseminating element. The apparatus is useful, for example, for purifying air and adding fragrance thereto.

Abstract: A device adapted to disseminate a volatile liquid, such as a fragrance, into an atmosphere comprises a reservoir (1) containing the liquid (6) and a capillary means (8) for conveying the liquid from the reservoir to the atmosphere. The reservoir has an upper orifice (2) into which the capillary means fits loosely. This orifice is in liquid-tight contact with a tubular member (3), which extends downwards into the reservoir, the tubular member and reservoir being proportioned such as to define a liquid-retaining volume regardless of the orientation of the device. The liquid is preferably introduced by means of a sealed cartridge (5), which may be supplied separately or as an integral part of the device. The device allows the use of a wide variety of capillary means and has the advantage of being spillproof.

Abstract: An apparatus adapted to release individually into an atmosphere one of at least two volatile liquids, each liquid being in heat transfer contact with one face of a theromoelectric device, typically a Peltier device. The apparatus allows the emission of different liquids at different times.

Abstract: An apparatus adapted to disseminate volatile liquid into an atmosphere, the apparatus comprising at least one evaporation element having at least one evaporation surface bearing at least one capillary channel and at least one wick, the wick making contact with the evaporation element at a surface other than the one bearing the capillary channel.

The evaporation element is preferably a capillary sheet. The apparatus allows the use of wicks that are smaller than usual, with no loss in efficiency of dissemination. It is also cheaper and more convenient to manufacture.

Abstract: An apparatus adapted to disseminate volatile liquid into an atmosphere from a reservoir, the transfer to atmosphere being achieved by means of a porous transfer member that transfers liquid from the reservoir to an evaporation surface. The evaporation surface is a capillary sheet substantially transversely from the transfer member, and being further characterized in that the material of the sheet is a plastics material having a Shore D hardness of from around 50 to 80 and a thickness of from 0.75-1.25 mm. These sheets make especially good liquid transfer contact with the transfer member.

Abstract: An apparatus for the dissemination of volatile liquid, such as a fragrance, into an atmosphere comprises a reservoir (1) containing volatile liquid (2) and at least one liquid transfer member (12) that is adapted to transfer liquid from the reservoir to the atmosphere. The transfer member is separated from the liquid, prior to putting the apparatus into operation, by a wall (5) having at least one breakable section (7), there being present at least one breaker element (11) that, when the apparatus is put into operation, is capable of breaking through the breakable section on being urged into contact therewith, thereby exposing the transfer member to the liquid. The transfer member preferably comprises capillary channels.

Abstract: An apparatus adapted to disseminate volatile liquid into an atmosphere comprises a reservoir containing volatile liquid and a liquid transfer member that transfers liquid from the reservoir to the atmosphere via an orifice in the reservoir. The reservoir orifice is closed by a puncturable membrane, and the transfer member is mounted adjacent to the orifice on the side of the membrane remote from the liquid and adapted such that it can be pushed through the puncturable membrane into, and then held in contact with, the liquid in the reservoir, to permit the flow of the liquid from the reservoir to the atmosphere. The liquid transfer member preferably comprises capillary channels. The apparatus has the advantage of being leakproof in transit.

Abstract: A device adapted to disseminate vaporous material, such as a fragrance, into an atmosphere by means of forced ventilation acting on an evaporation surface (6) supplied with a liquid volatile material that is vaporised thereby, the evaporation surface being essentially planar and having an orientation generally parallel to the direction of the forced ventilation. The ventilation is preferably supplied by an electrically-powered fan (8).

Abstract: An apparatus adapted to transmit an active substance in the vapour phase to an atmosphere, comprising an active substance incorporated in a sublimable carrier substance (12) and a heating element (4) that interfaces with only part of the total sublimable carrier substance, carrier substance and heating element being so arranged that the sublimable carrier substance subliming at the heating element/sublimable carrier substance interface is replaced by further sublimable carrier substance. The apparatus is not prone to spillage, as are current volatile liquid-based apparatus. It also allows the easy observation of the approaching end of life of the carrier substance/active substance and its need for replacement, so that continuity of transmission is assured.

Abstract: An apparatus adapted to disseminate a volatile liquid, such as a fragrance, an insecticide or a fungicide, into an atmosphere, the apparatus comprising a reservoir containing the liquid and a porous transfer member through which the liquid is conveyed from the reservoir to the atmosphere, the apparatus additionally comprising means of pressure equalization between atmosphere and reservoir, which means is adapted to effect a pressure-equalising change in volume of the reservoir, when the apparatus is in operation. The apparatus does not suffer from the leaking problems of known apparatus of the same kind, and is especially useful in apparatus in which one of two liquids, particularly fragrances, may be singly dispensed, by the inversion of the apparatus.

Abstract: A device adapted to provide volatile liquid material to an atmosphere comprising a reservoir (1) containing volatile liquid material, a rod-like transfer member (3, 4) extending therefrom and adapted to transfer liquid from the reservoir, and at least one diffusion surface (7) adapted to receive the liquid from the transfer member and facilitate its evaporation into the atmosphere, the diffusion surface extending essentially laterally from the transfer member and comprising at least one non-integral, non-porous sheet bearing a surface capillarity (9), which sheet has an extent and a capillarity sufficient to allow an appropriate evaporation. The device is cheap and easy to construct, versatile and diffuses odour without major changes of the odour over time.
