Description

A FRAGRANCE GENERATING DEVICE This invention relates to a fragrance generating device incorporating an interchangeable heat source.

Fragrance generating devices, hereinafter referred to as fragrancers, are well known. They are manufactured in a variety of forms, eg aerosols, fragrant pads and those powered by electrical means. Powered fragrancers similar to the proposed invention, described herein, are known, however, they have a number of limitations, some of which are outlined below: 1. The heating element in the known powered fragrancers is not readily replaceable, therefore, in the event of its failure the device will generally be rendered useless.

The proposed invention may overcome this limitation in that the design of the fragrancer could provide means to enable the heating element to be removed and replaced, ie be interchangeable. Furthermore, if the heat source was a common light bulb, which can be purchased from many retail outlets, then the power rating of the light bulb could be chosen to best suit the needs ofthe user, ie high power for rapid fragrance emission and low power for a more gradual emission rate.

2. The fragrance holding component of the device in the known fragrancers, hereinafter known as a holder, is not refillable. Therefore, to continue using a fragrancer after all of the fragrance substance in the holder has been used up, the user needs to find a retail outlet that supplies the holders or contact the manufacturer of the holder; if however the holder was then obsolete / discontinued then the device would be of no further use.

The proposed invention overcomes this limitation in that the holder may be made such that it may be refilled with fragrance substance. In addition, since the proposed device could make use of aromatic oils which have been around for thousands of years and are available today in hundreds if not thousands of retail outlets, the user of the device would have the choice of many hundreds of fragrance substances with which to refill the holder. This feature would be particularly desirable for Aromatherapists who may wish to use their own specific blends of essential oils.

3. The fragrance generation / emission rate in the known powered fragrancers is not controllable, either when it is powered or not, at least, not to the extent whereby all fragrance liberation from the device can be stopped. As a result of this limitation there are instances where fragrance will be liberated even when the device is not powered, eg when the ambient temperature is high, like on a hot summers day or, the fragrancer is placed near to an external heat source or in direct sunlight. In such instances there are many reasons why it would be desirable to provide means to prevent fragrance generation from the device, eg in the event of having to leave pets in a vehicle which utilises a fragrancer, on a hot sunny day.

The proposed invention overcomes these problems in that it could be made such that it provides means to prevent fragrance liberation from the device when the device is not powered. In addition, means may also be provided to regulate the fragrance generation rate when the fragrancer is powered.

4. In the known fragrance generating devices the only way to tell how much fragrance substance is left in the fragrance substance holder is to remove the holder and either visually inspect it or smell it. These means often rely on the users judgement and it may well be that although the holder visually seems to contain fragrance substance, in actual fact it is only the substance with which the fragrance substance had been mixed with, eg a gel. In addition, smelling a fragrance substance holder close up will almost certainly make the user think that there is still fragrance substance left, however, this is not necessarily a true indication that the holder still contains sufficient fragrance substance for the device to function as it should.

The proposed invention can overcome this limitation in that the fragrance substance may be visible through the device's form. This may be achieved in many ways, eg fabricating the holder out of transparent materials, incorporating into the holder a transparent window, or by virtue of the heat source which, in the case of a light bulb, can cause a material that normally looks opaque to become partially transparent.

5. In many known fragrancers the fragrance substance from which fragrance is to be emitted is encapsulated in a gas only permeable holder. The said holder fits into the fragrancer and is heated externally, in order to liberate the fragrance. This indirect heating arrangement has the limitation that a low power external heat source is required, so as not to melt the holder or the gas permeable material, which in turn results in a poor, often unnoticeable, fragrance emission rate from the holder. In addition the low fragrance emission rate from this particular type of holder is not helped by the fact that the vapours derived from heating aromatic substances comprise minute droplets, ie the vapours are not purely gaseous, and as such do not readily penetrate gas only permeable surfaces. This low fragrance emission rate feature associated with this type of fragrancer, whilst perhaps having its advantages, has a number of disadvantages also, some of which are outlined below: A: If the liberation of a fragrance is required quickly, eg during cooking activities or after smoking a cigarette in a motor car, then the known devices will fall short of this requirement since they are not capable of rapid liberation of fragrance.

B: The fragrancer may not be able to fragrance a large room due to the dissipation of the fragrance by normal room ventilation.

C: The user may think that the device is simply not working or the fragrance substance in the holder is all used up.

In other known fragrance generating devices the fragrance substance is impregnated into a solid or porous form which may be internally or externally heated in order to enhance the liberation of fragrance from the form. In these devices the same limitations as identified above will apply, ie those associated with power considerations and the fact that the fragrance substance is bound in a lattice which will tend to inhibit rapid fragrance emission from the device.

The proposed invention overcomes these limitations in that it can provide means to draw the fragrance substance from within its holder to a position on the outer surface of the holder, such that when the fragrance substance is heated, locally to this point, fragrance substance vapours may escape the holders form without the hindrance of gas only permeable films or lattice structures as described.

According to the present invention there is provided a fragrance generating device incorporating an interchangeable heat source.

A specific embodiment of the proposed invention, adapted for use in the cigarette lighter socket of a vehicle, is described by way of example with reference to Figure 1 and other Figures where stipulated. A number of other possible embodiments of the proposed invention are briefly described with reference to Figures 2 to 6. In addition a number of possible enhancements, generally generic to all embodiments ofthe proposed invention, are described.

Figures 1 to 7 illustrate, in cross-section, possible embodiments of the proposed fragrance generating device adapted for use in the cigarette lighter socket of a vehicle.

Referring to Figure 1 the fragrance generating device basically comprises a housing (I) and two contact assemblies (2) and (3), for making connection to a source of power (not shown) and the terminals ofthe device's heat source, which in this example is a light bulb (4) which is located into the housing (1). A fragrance substance holder (6) is located in a cap (5) which is releasably secured to the housing (1). The holder (6) incorporates a releasably secured lid (7) incorporating an absorber (8), which in this example provides means to draw fragrance substance from the reservoir (9) to the light bulb (4). The fragrance liberated from the absorber (8), by the light bulb (4), escapes from the device via suitably positioned perforations (10) in the cap (5). To use the invention as described above, the holder (6) is inserted into the cap (5) which is then releasably secured to the housing (1). The device is then located into the vehicle cigarette lighter socket causing the light bulb (4) to be powered and fragrance to be liberated from the absorber (8). Individual components ofthe device are discussed in more detail below, with reference being made to Figure 1. Note, these more detailed descriptions of the components are not necessarily specific to the embodiment of Figure 1, but rather the device as described herein, eg where a description refers explicitly to a light bulb the description could be equally applicable to an alternative heat source.

Housing (1) The housing (1) as shown in Figure 1 is an open topped, typically cylindrical, form with a part formed base enabling insertion of a contact assembly (2). The other contact assembly (3) is in some way attached / located to the body of the housing (1), eg by an electrically conductive bolt or similar I known connection means.

An oil seal, or similar known means, may be provided between the cap (5) and the housing (1) to prevent fragrance substance leaks from the device, eg in the event of loss of containment of the fragrance substance through the absorber (8).

The housing (1) may provide means (not shown), eg a screw thread, clip or other known connection means which may be co-operable with the cap (5), enabling the cap (5) to be, directly or indirectly (not shown), releasably secured to the housing (1).

Contacts (2) and (3) The said contact assemblies, (2) and (3), serve to connect the terminals of the light bulb (4) with the bottom and sides of the vehicle cigarette lighter socket (not shown) which in turn make connection to the vehicles battery.

The contacts may be made such that they can make the appropriate connections with cigarette lighter sockets in all vehicles, ie they form a universal connection means for the device.

The contacts may be such that they provide a heat sink, or connection to a heat sink, to remove excess heat generated by the heat source which may otherwise compromise the integrity of the device's components, particularly plastic ones, due to overheating. If required, a heat sink may be provided by one or more of the other components described herein, or an additional component / assembly.

The contacts need not necessarily be separate components, eg the housing (1) could be suitably shaped and fabricated from an electrically conductive material so as to form a contact.

Heat Source (4) In the embodiment illustrated in Figure 1, the heat source is a light bulb (4) located in the housing (1). The purpose of the light bulb (4) is to in some way provide heat to the fragrance substance to promote fragrance generation.

The light bulb (4) may serve an additional function in that it could, in some way, visually inform the operator that the device is functioning.

The light bulb (4) may serve an additional function in that it could enable the operator to gauge the amount of fragrance substance in the device, eg by illuminating the holder thus causing the fragrance substance to be visible, eg by virtue of its shadow.

The light bulb (4) could be releasably secured in the device to enable its removal and replacement, ie it could be interchangeable / replaceable. These said releasable securing means could be universal in that a wide variety of light bulbs, ie different shapes and power ratings of light bulb, or indeed alternative heat sources, could be utilised by the device.

The light bulb (4) may also be incorporated into other component(s) or their associated assemblies, eg the cap (5) or the holder (6), the latter being illustrated in Figure 7.

The heat source may be other than a light bulb, eg an electrically resistive component. If such an alternative heat source were used then the device could incorporate a visual indicator, eg an electrically powered light source suitably incorporated into the electrical circuit of the heat source, or connected in some way to the device's source of power, to visually inform the operator when the device is functioning. Furthermore, if a heat source other than a light bulb were used then it could still provide a number of the features as described above, eg it could be replaceable.

Cap (S) The cap (5), as shown in Figure 1, houses the fragrance substance holder (6) and is sized such that when it is releasably secured to the housing (1), the absorber (8) is suitably positioned, with respect to the light bulb (4), to enable it to warm up and liberate fragrance from its form.

The cap (5) is suitably perforated (10) to allow the fragrance evaporated from the absorber (8), by the heat from the light bulb (4), to escape from the device (1).

Fragrance holder (6) The fragrance substance holder (6), as shown in Figure 1, comprises a receptacle, typically cylindrical in form, with a lid (7). The lid (7) is perforated and incorporates a means, ie an absorber (8), to draw fragrance substance from the holder's reservoir (9) to the light bulb (4) which may be external to the holder's form (6). The said absorber (8) prevents fragrance substance leaking out of the holder (6) by covering the perforations in the lid (7), which may be releasably secured to the holder (6), eg by screw thread or other known / similar connection means. In this way the lid (7) can be removable thus allowing the option to refill the holder (6) with a fragrance substance of the users choice.

The fragrance holder may also be such that there are no readily available means by which it may be refilled.

The fragrance holder may also be integral to other components of the device, eg the housing (1) as shown in Figures 5 and 6, or the cap (5) as shown in Figures 2 and 3.

Absorber (8) The purpose of the absorber (8), in the embodiment shown in Figure 1, is to provide means to draw the fragrance substance from the holder's reservoir (9) to a position on the surface of the holder's form, whereat, the heat from the light bulb (4), which in this example is external to the holder (6), promotes fragrance liberation. As the heat from the light bulb (4) evaporates the fragrance substance from that part of the absorption pad (8) in contact with, or close to, the light bulb (4), more fragrance substance is drawn to that part, thus, enabling further fragrance substance evaporation.

The absorber (8) could be such that it may be removed from the lid (7) for insertion of a new absorber (8) or for cleaning as appropriate. The absorber (8) may also be such that all of the fragrance substance may be held up in its form, ie the absorber becomes the holder.

The absorber (8) in this example is a material pad having the properties of being able to absorb fragrance substance yet retain it within its form.

The function of the absorber (8) may be realised by other means (not shown), eg a unit working on the principle of capillary action or provision of electrical or mechanical means, eg a plunger arrangement enabling the operator to force the fragrance substance from the reservoir (9) to the light bulb (4), or similar means.

The shape and positioning (not specifically shown) of the absorber (8) could be such that all, or at least a high percentage, of the contents of the reservoir (9) could be evaporated by the light bulb (4).

Perforation(s) (10) The perforation(s) (10) in the device's form in this particular example are located in the cap (5). The said perforation(s) could however be located on one or more of the devices components, eg cap (5) and housing (1), or another form (not shown) in some way attached / located to the device, eg a perforated component in some way located between the housing (1) and the cap (5).

The perforation(s) could in some way be adjustable, in a number of dimensions, to enable regulation of the fragrance substance liberation from the device, eg in a way similar to that on the top of a pepper dispenser, or similar means.

Other possible embodiments of the proposed invention will now be described with reference to Figures 2 to 6. In general, only those features of the said other embodiments which are different or additional to the embodiment already described, with reference to Figure 1, will be described. Therefore, if an embodiment refers to, for example, a light bulb, then since the light bulb has been described by reference to Figure 1, the same features as described may apply to the embodiment being described, eg the light bulb may be replaceable, the heat source may be other than a light bulb etc. To this end the components of these other embodiments similar to those already described, retain their identifying numbers as used in Figure 1.

In the embodiment of the proposed invention, as illustrated in Figure 2, the holder (6) is integral to the form of the cap (5). In such an arrangement the fragrance substance may be inserted into the cap (5) via an opening in its form. A means to seal the opening, eg a removable plug (11), may be provided to prevent the fragrance substance flowing out of the opening when, for example, the cap (5) is full of fragrance substance and the device is on its side as shown.

In the embodiment of the proposed invention, as illustrated in Figure 3, the light bulb (4) is in direct contact with the fragrance substance reservoir (9). In such an arrangement it would be desirable for the light bulb (4) to be in some way sealed into the housing (1). These sealing means may be realised by, eg a tight fit between the light bulb (4) and the housing (1) or, an oil ring (12) as shown, or other known / similar means. Fragrance substance may be inserted into the cap (5) via an opening in its form which could also be utilised as a suitable means to let fragrance substance vapours escape from the device. In addition a means to control the rate at which fragrance substance vapours escape from the device could be provided, eg by a perforated form (13) inserted into the said opening in the cap (5) and means, eg a screw on cap (14), to cover or uncover the perforations, or similar means. The said cap (14) could also provide a means to seal the fragrance substance into the device thus preventing any fragrance emission or fragrance substance spillage from the device, eg by screwing the cap (14) to a position such that the said perforation in the perforated form (13) are covered.

In the embodiment of the proposed invention, as illustrated in Figure 4, the fragrance substance holder (6) is located in the housing (1). In such an arrangement the positioning of the fragrance substance holder (6) may be governed by means (not shown), eg stops within the housing (1), integral to, or externally attached to, the housing (1) and or holder (6) itself, or other known / similar means.

In the embodiment ofthe proposed invention, as illustrated in Figure 5, the light bulb (4) is in direct contact with the fragrance substance reservoir (9) which is contained within the form of the housing (1). In this arrangement the heat from the light bulb (4) heats up a thermally conductive component or assembly (15), which in turn heats up the absorber (8). The fragrance substance vapours created in the reservoir (9) and the bulk of the absorber (8) will not readily escape, due to almost immediate condensation, however, the fragrance substance vapours that has been drawn to the outer side the absorber (8) will escape from the absorber (8), thus the device will emit a fragrance. The device in this form could be refilled with a fragrance substance, by removal of the cap (5) which could be releasably secured to the housing (1).

In the embodiment of the proposed invention, as illustrated in Figure 6, the light bulb (4) is internal to the fragrance substance holder, which in this case is the housing (1). Means are provided to draw fragrance substance from within the holder's form to a position on the surface of, or external to, its form, where the said holder's form may also comprise the drawing means. In this arrangement the light bulb (4) could be releasably secured to an electrically conductive form (20) which may itself be secured in the housing (1) by an electrically conductive bolt (21). Insulating material may be provided between the conductive form (20) and the bottom terminal of the light bulb (22). The contact (2) and the contact assembly, comprising components (3) and (20) and (22), may act as a heat sink for the removal, from the device, of excess heat generated by the light bulb (4). The cap (5), in this embodiment, provides catchment means (16) for condensed, or leakage from the absorber (8) of, fragrance substance. These catchment means are provided by virtue of the shape of the cap (5) and the fact that any fragrance substance caught up in the said catchment means may be reabsorbed by the absorber (8). A means to prevent any fragrance substance vapours escaping from the absorber (8) when the device is powered or not may be provided by a removable plug (18) which seals the opening through which fragrance substance vapours normally escape from the device. For convenience, the cap (5) in this embodiment may incorporate a holding means (19) for the plug (18). These holding means could also be incorporated into other components of the device.

In a variation to the embodiment shown in Figure 6, the fragrance substance may be entirely held up in the absorber (8). In such an arrangement the user could refill the device with fragrance substance by, removing the cap (5) or plug (18) and adding fragrance substance direct to the absorber (8), or by replacing the absorber (8) with a new absorber (8) containing fragrance substance.

In addition the proposed invention may incorporate additional features as described below, and with reference, where possible, being made to Figure 1. Note, these additional features are not necessarily specific to the device described in Figure 1, eg if a spring mounted light bulb is described, this could also relate to a spring mounted heat source, or if the fragrance generation rate from a holder were referred to this could also relate to the fragrance generation rate from another component of the device, eg the housing.

The power source for the heat source may be internal, eg a battery, or external to the device, and may also be used to power additional components, eg a fan or vibration device which could enhance fragrance liberation from the device The proposed invention may incorporate a switching means to enable connection / disconnection of the device to its source of power. The switching means could be provided by, eg a standard electrical type switch, or a switch utilising movement of one or more of the device's components, eg, with reference to Figure 1, the securing of the cap (5) to the housing (1), when the holder (6) is in place, could causes the movement of a spring mounted (not shown) light bulb (4) and a contact to be made, thus powering the device, or the contacts, (2) and (3), could be made and positioned such that withdrawing the device slightly from the vehicle cigarette lighter socket would cause a contact to the said power source to be lost, or other known / similar means.

The proposed invention may be provided with means by which the user of the device can visually determine how much fragrance substance there is in its holder. Such means could be provided by, eg a transparent window between the fragrance substance holder and the outside surface of the device's form, or by fabricating one or more of the device's components from transparent materials, or other known / similar means. In addition, use of a light bulb as a heat source may sufficiently illuminate the device such that it becomes partially transparent, thus enabling the user to gauge the amount of fragrance substance in the holder by virtue of its shadow.

The proposed invention may be provided with means to prevent fragrance substance vapours escaping from the device, when the device is in use or not. These means may be afforded by, for example, an additional cap which fits over the lid (7), a means to compress the absorber (8) such that no fragrance substance can be absorbed into its form, a means to block the perforation(s) from which the fragrance substance vapours, directly or indirectly escape from the device's form, eg by means to position the light bulb (4) tight up against the lid (7) or a means to block the perforation(s) in the device's form, eg a plug as illustrated in Figure 6 or means similar to that on the top of a pepper dispenser as already mentioned, or any combination of the above or similar / known means.

In the event of a loss of containment from the holder (6) due to a breach in the absorber (8), or in the event of fragrance substance vapours collecting in the device's form due to condensation, the proposed invention may be provided with means of catching and or trapping the resulting pool of fragrance substance. These means could be integral to the design of, for example, the lid (7), as shown in Figure 6, the holder (6), the housing (1), or other component of the device, or be a separate component, eg the intermediate component or assembly as described below, or similar / known means..

The proposed invention may be provided with means to enhance / control the fragrance emission rate from the holder / device, for example, referring to Figure 1, an intermediate component or assembly (not shown), eg a cylindrical perforated tube or disc, could in some way be positioned in the device, eg between the light bulb (4) and the absorber (8), to enhance the fragrance evaporation rate from the holder (6). This enhancement of the fragrance liberation from the holder (6) could be by way of increasing the heat affected area of the absorber (8). If the said intermediate component or assembly were provided with means to make it moveable in some way then there could be scope to provide control of fragrance substance evaporation by, eg moving the said intermediate component or assembly in such away that the heat affected area on the absorber (8) is altered. The means to enhance / control the fragrance substance evaporation rate from the holder (6) could be provided by means other than the said intermediate component, eg by provision of means to regulate, or switch on and off, the power to the light bulb (4), or light bulbs, or alter the heat affected area of the absorber (8), eg by movement of the holder (6) relative to the light bulb (4), or provision of a thermostat, possibly adjustable, to, eg control the temperature to which the absorber (8) is subjected, or means to compress the absorber (8) such that less fragrance substance is absorbed into its form, or means to alter the dimensions of the perforation(s), through which fragrance substance vapours pass, or any combination of the above or similar / known means.

The said intermediate component or assembly may also provide means, eg by virtue of its shape, to aid in the containment of fragrance substance in the holder (6). Means to aid in the containment of fragrance substance in the holder (6) could be provided by means other than the said intermediate component or assembly, eg by forms integral or in some way attached / located to one or more of the devices components.

The device may also be made utilising any combination of the features herein described by way of example with reference to Figures 1 to 7. The device described may also be adapted for use in a standard household type electric wall plug or for use in a standalone unit in some way connected, eg by electrically conducting cable to a power source. In addition the device may also be incorporated into a device that already serves one or more functions, eg a vehicle cigarette lighter, the light unit in a fridge, a vacuum cleaner and so on.
