Abstract: Devices having one or more transfer elements (wick, emanator) formed from plant material derived from the stems of sola plants from the genus Aeschynomene L., family Fabaceae in air fresheners or evaporation devices for other actives (fragrances, insecticides, fungicides, pharmaceuticals). Methods of assembling a device having one or more transfer elements (wick, emanator) formed from plant material derived from the stems of sola plants from the genus Aeschynomene L., and for using the device to transfer or evaporate liquids containing active are also provided. The material when used in form of a wick or emanator shows excellent liquid transfer and of both aqueous and non-aqueous liquids and a low fractionation of a mixture of actives.

Abstract: A candle comprising a body of combustible wax and a wick, there being dispersed within the body inclusions of a combustible wax that has a higher melting point than has the wax of the body, said inclusions comprising a modifier, typically a fragrance or a pyrotechnic substance.

Abstract: Improved transfer elements (wick, emanator) of plant material including material derived from the stems of plants of the family Fabaceae selected from a plant of the genus Aeschynomene, a plant of the genus Sesbania, and a plant of the genus Robinia, and devices having at least one such transfer element including air fresheners and evaporation devices for other actives (fragrances, insecticides, fungicides, pharmaceuticals). Methods of assembling a device having at least one transfer element, and for using the transfer element or device to transfer or evaporate liquids containing active are also provided.

Abstract: An apparatus adapted to spray into an atmosphere a volatile liquid, the apparatus comprising an aerosol container (12) comprising a liquid-containing vessel with spray-actuating button (11), the aerosol container being fixed to the apparatus by means of a resilient support member (15,16) integral with the container, the container having a rest position, in which the button is in a non-depressed position in relation to a pressure pad (10) fixed within the apparatus, and a spray position, in which the button is in spray-actuating contact with the pressure pad against the resilience of the resilient member seeking to maintain the rest position. The apparatus is simple to construct and operate, and may be constructed such that only appropriate refills can be used.

Abstract: An apparatus adapted to disseminate a volatile liquid, for example, a fragrance, into an atmosphere, the apparatus comprising a reservoir containing the liquid and a porous liquid transfer member through which the liquid is conveyed from the reservoir to the atmosphere and from which part extending into the atmosphere it is disseminated, the reservoir consisting of a collapsible bladder that reduces in volume responsive to atmospheric pressure and the loss of liquid, the porous transfer member being encased in an impermeable sleeve that is open to the liquid at that end of the member remote from the that part in the atmosphere, the transfer member additionally comprising at or adjacent to the open end means that interact with the collapsing bladder to maintain liquid contact with the transfer member.

Abstract: A device adapted to disseminate one of a plurality of volatile liquids into an enclosed atmosphere, the device comprising (i) an enclosure (1) within which is defined a plurality of separate compartments (3,4), each compartment having at least one inlet and at least one outlet port (10, 9), and within the compartment, a source of volatile liquid (5), (ii) a source of forced air current external to the compartments and adapted to blow air through them into the atmosphere; characterised in that the device additionally comprises automatic liquid regulating means in the form of paired port closures (11, 12) for both inlet and outlet ports of each compartment, slidable between a number of inlet and outlet port-closing rest positions equal to the number of compartments, such that, in any rest position, the inlet and outlet ports of only one compartment are open.

Abstract: A plug-in device adapted to disseminate a plurality of volatile liquids, such as fragrances, individually into an atmosphere, the device comprising a plurality of volatile liquids and a dissemination means, the liquids being accommodated on a rotatable wheel, which wheel is rotated such that the individual liquids come into liquid disseminating proximity to the liquid disseminating means. The device substantially overcomes the problem of “habituation” encountered with a single fragrance air freshener.

Abstract: A device adapted to disseminate into an atmosphere in a desired sequence and timing, a plurality of active volatile liquids, such as fragrances, comprising a plurality of individual liquid reservoirs, a dissemination element associated with each reservoir, a source of forced air current and a conduit from the source of forced air current to each dissemination element, the conduit being a single conduit that is adapted to be movable so as to supply air current to each dissemination element in a desired sequence. The device may be provided as a simple plug-in type and overcomes the problem of “habituation” encountered with a single fragrance.

Abstract: A device adapted to disseminate into an atmosphere in sequence a plurality of active volatile liquids, such as fragrances, comprising a plurality of individual liquid reservoirs, a dissemination element associated with each reservoir, a central source of forced air current and one air channel per reservoir leading from an entrance at the central source to each dissemination element, air current being provided to one channel at a time by means of an air-tight rotatable barrier comprising a plurality of apertures, the spacing of these apertures being adapted to close all but one entrance at any given time. The device may be provided as a simple plug-in type and substantially overcomes the problem of “habituation” encountered with single fragrance air fresheners.

Abstract: An active volatile liquid-dispensing device comprising a gel and a separate source of active volatile liquid (“the source”), the gel (a) comprising volatile material the emission of which causes the reduction in size of least one physical property of the gel, and (b) being equipped with a screening means that screens the source from the atmosphere, which screening means is caused to open by the size reduction in physical property, thus causing a progressively greater exposure of the source to the atmosphere with passage of time, the exposure of the gel to the atmosphere remaining essentially constant. The physical property utilised is usually reduction in weight or shrinkage in physical dimensions. The devices permit a more controlled release of active into the atmosphere and a longer life, and are especially useful as air fresheners.

Abstract: A volatile liquid emitting device, comprising an electrical heating element and a reservoir of volatile liquid, liquid and heating element being disposed in a heating relationship to each other and the heating element receiving electricity from an integral USB connector, the volatilised liquid passing into the atmosphere through a membrane that is impermeable to the liquid but permeable to the vapour thereof. The device is simple, easy to produce and use, and the contents cannot spill or leak.
