Abstract

The procedure consists of subjecting a block (1) of a solidified mixture containing a perfume to a source of heat so that the perfume is vaporized progressively and released into the ambient air. The procedure consists of subjecting a block (1) of a solidified mixture containing a perfume to a source of heat so that the perfume is vaporized progressively and released into the ambient air. The block is heated by a candle (7) at the bottom of a chimney (6) in a support (4), the candle maintaining a flame of constant height that does not make contact with the block. The block consists of a solidified mixture of 30 - 40 per cent by weight of the perfume and 60 - 70 per cent of components that are liquefied by the heat and return to a solid state when cooled: petroleum jelly, beeswax and stearine or bentone gel.

Description

The subject of the present invention is a method of diffusing perfume in

  ambient air, as well as a device and a product for

its implementation.

  This invention generally relates to the field of manufacturing household products intended to be diffused in an environment to modify the atmosphere, if necessary to create a particular atmosphere or mask any undesirable odors. For this purpose, there is currently a wide range of ambient products with varied scents, packaged in the most diverse forms, each of them determining a setting

in specific work.

  Thus, it is for example known to use perfume diffusers in the form of aerosols making it possible to vaporize punctually the quantity of product necessary for the expected result, at the place

Of his choice.

  The odor emitted thus is quickly lost in the atmosphere, and to maintain the desired atmosphere, it is necessary to regularly use aerosol in order to diffuse

a new amount of fragrance.

  Consequently, if this perfume diffusion method allows a particularly rapid and practical implementation, it is limited to brief use within a fairly small volume and is not really suitable for the diffusion of an odor during several hours through the whole of an apartment or a dwelling house. Other products consist of scent diffusers comprising a solid support on which a perfume is retained in the liquid state and from which it is gradually exhaled, once put

in contact with air.

  But, here again, these are products and processes designed mainly for use inside small volumes, and which are generally used to mask odors, for example in cars, or shoe cupboards , etc. Finally, when one wishes to diffuse a fragrance gradually and continuously in the ambient air, one has

2 2847477

  traditionally rather use of perfume burners or scented candles whose principle is to release a fragrance

  vaporizing under the effect of a heat source.

  Thus, the perfume burners are defined by receptacles in which, as their name suggests, an essence is placed to make it burn, so as to cause vaporization and diffusion

  in the atmosphere of the aromatic compounds it contains.

  This principle, although often pleasant from an aesthetic point of view, however has the disadvantage of sometimes delicate handling and above all of requiring a large amount of gasoline, all the aromatic compounds being immediately exhaled

  when their vaporization point is reached.

  As for the scented candles, they are not more satisfactory, since it has been observed not only that 50 to 60% or even 100% in the case of misuse - the odoriferous substances they contain are consumed directly in the flame , due to the combustion of the central wick, but in addition it was sometimes necessary to wait more than half an hour, depending on the size of the candle, before perceiving the diffusion of an odor coming from the vaporization of the substances located on the outskirts

of the latter.

  Therefore, this scented candle system is not

  satisfactory neither for the manufacturer nor for the consumer.

  The first is, in fact, forced either to increase the proportion of perfume contained in the product in order to compensate for the losses linked to the combustion of the candle, or to produce candles in which this substance is only placed the periphery, which in both cases poses a problem

  cost and / or manufacturing difficulty.

  As far as the consumer is concerned, he will not only have to bear the high cost of these candles, but also the disadvantage of the long delay to be expected before the appearance of the effect.

expected ambiance.

  The present invention therefore proposes to provide a solution to these drawbacks, firstly by means of a process for diffusing perfume into the ambient air, in which a

3 2847477

  solid mixture containing an odorous substance at a heat source, so as to cause a progressive vaporization of said odorous substance and its release into the atmosphere, characterized in that it consists in heating said solid mixture to a given and relatively constant temperature , while isolating it from

contact with a flame.

  We thus manage, in a particularly advantageous manner, to give off a persistent odor instantaneously and in an optimized manner, since no fraction of odoriferous substance is consumed to maintain the heat source, which is

  powered by its own fuel.

  Furthermore, according to a particularly advantageous characteristic of said process, a solid mixture is used containing compounds capable of liquefying under the effect of said heat source to allow the vaporization of said odorous substance, then to return to the state solid when removing said heat source by reincorporating the not yet vaporized fraction of said

odorous substance.

  This makes it possible to quickly stop the emission of perfume, as soon as a period of use is ended, without loss of odorous substance, any fraction of the latter which is not yet diffused in the ambient air being immediately re-encapsulated by said compounds when they return to the solid state on cooling. According to a first embodiment, the method according to the invention is also characterized in that a solid mixture is used containing by weight 5% to 30% of the odorous substance and 70% to 95% of the compounds capable of liquefy under the effect of said heat source and return to the solid state when

removes said heat source.

  In this case, the mixture used is in the form of a solid body of variable shape and size, which can be reused successively, until it is completely consumed. According to another preferred embodiment, the present method provides for using a solid mixture containing by weight 30%

4 2847477

  40% of the odoriferous substance and 60% to 70% of a mixture comprising compounds capable of liquefying under the effect of the heat source and of returning to the solid state when said aforementioned is removed

  heat source and thickening compounds.

  The mixture is defined here by a paste which can, for example, be contained in a tube and the quantity of which distributed or consumed each time is determined by the user as a function

of his needs or wishes.

  On the other hand, the present invention also relates to a device for implementing the method as described above, characterized in that it comprises a support comprising, at its upper part, a receptacle intended to receive the solid mixture , said receptacle surmounting a

  chimney at the base of which is placed the heat source.

  According to a first characteristic of said device, the heat source is defined by a candle capable of being consumed while

  retaining a substantially constant flame height.

  This particularity has the advantage of guaranteeing the constant nature of the temperature diffused by the heat source towards the solid mixture and consequently of allowing a regular exhalation of the perfume, avoiding the effects of drop in intensity.

  linked to a possible drop in temperature.

  According to an additional characteristic intended, if necessary, to improve the aesthetics of the device according to the invention, the latter is further characterized in that the receptacle is provided

  a cover, possibly provided with orifices.

  According to another characteristic, the receptacle and the chimney are moreover made of a conductive material, such as in particular aluminum, so as to accelerate the diffusion of the

warmth and that of the scent.

  In addition, the present invention also relates to a product for implementing the method, which is characterized in that it consists, by weight, of 30% of odorous substance, 50% of petrolatum,

  % white beeswax, and 10% stearin.

  According to another formulation which is equally conceivable, the present invention also relates to a product for the implementation

- 2847477

  work of the process which is characterized in that it consists of 40% odorous substance, 51% petrolatum, 3% beeswax

white, and 6% bentone gel.

  The invention will now be better understood on reading the

  description which follows, referring to examples of

  realization given as an indication and not limiting.

  The understanding of this description will be facilitated in view of the

  attached figures in which: - Figure 1 and Figure 2 each represent a possible mode of packaging of a product used for placing

of the present process.

  - Figure 3 shows a schematic perspective view of a device for implementing the method according to the invention. The present invention relates to a method of diffusing perfume into the ambient air, which is based on the use of a device and of a product making it possible to increase the efficiency and the quality of this diffusion, while being very simple. to manufacture

  and inexpensive for the consumer.

  Such a method in fact provides for subjecting a solid mixture in which an odorous substance is trapped, to heat, in order to cause the release and vaporization of this odorous substance in the atmosphere, excluding any untimely loss or waste. . Such vaporization is obtained, according to the present process, by using a heat source independent of said mixture.

  solid, and powered completely independently.

  With such a process, the solid mixture is not consumed by the heat source; and, on the contrary, it excludes, in a particularly advantageous manner, any loss of odorous substance in the combustion of a possible wick, while benefiting only from the benefits of the heat source which stimulates the diffusion of the perfume. On the other hand, so as to allow a gradual implementation of the present process, during possible sessions which follow one another over time, a solid mixture is used whose

6 2847477

  compounds have physicochemical characteristics their

  allowing to change state under the effect of temperature.

  Thus, said compounds have, more precisely, the ability to liquefy, depending on their nature, as the temperature to which they are subjected increases, which gradually makes it possible to deliver and obtain the vaporization of the odorous substances which they retain when they are in the state

solid, at room temperature.

  This liquid state is, moreover, reversible, and these compounds return to the solid state on cooling, while trapping at

  new residual odorants.

  The present method further provides for the use of solid mixtures of variable composition, which can therefore exhibit at room temperature differences in consistency, which are

  determining for their packaging and their mode of use.

  Thus, according to a first possibility, it is possible to use a solid mixture containing, by weight, 5% to 30% of said odorous substance and 70% to 95% of compounds capable of liquefying under the effect of said heat source. and return to the solid state when

removes said heat source.

  Such a solid mixture is hard at room temperature and is, as shown diagrammatically in FIG. 1, in the form of a block 1, in particular cubic, very easy to handle, whose melting point is 500C, and which offers, by example for a 30 mm cube

  aside, a total burn time of approximately 20 hours.

  Of course, it is possible, by the present method, to use blocks 1 of variable shape and dimensions, or even to use several simultaneously, in particular with a view to obtaining the

  diffusion of a mixture of perfumes simultaneously.

  According to another possibility, it is also possible to use a solid mixture containing, by weight, 5% to 30% of said odorous substance and 70% to 95% of compounds capable of liquefying under the effect of said heat source and to return to the solid state when

removes said heat source.

  This mixture has, in this case, the appearance of a conditioned dough, as shown in Figure 2, for example in a

7 2847477

  tube, or any other container suitable for easy handling, said paste being able to be consumed as required, as and

  measurement of the implementation of the present process.

  It will be readily understood that this mode of packaging allows the user to easily manage the duration of implementation of the present method as a function of the quantity of dough subjected to said

heat source.

  The present invention also also relates to a device 3 for implementing the method described above,

  an example of which is shown diagrammatically in FIG. 3.

  Such a device 3 consists of a support 4, which has been shown here in the shape of a parallelepiped, but which could, of course, have other more original aspects which can be combined

  with multiple styles of decoration.

  This support 4 is at least partially hollowed out and is provided, preferably at its upper part, with a receptacle 5 capable of receiving said solid mixture, in the form of block 1, as well

than dough 2.

  The device 3 further comprises a chimney 6, constituted by a cylindrical pipe, making it possible to connect the receptacle 5 to a heat source 7, introduced inside the support 3 through an orifice 8, and positioned at the base of said chimney 6. The latter also has a height adapted as a function of the melting point of the solid mixture placed in said receptacle 5, which must be able to be reached as quickly as possible, and kept constant throughout the setting period.

process work.

  In the same spirit, according to another particularly advantageous characteristic, making it possible to optimize the efficiency of the present process of diffusing perfume, the heat source 7 is of the type capable of delivering a constant temperature throughout

the use of the device 3.

  Thus, it is for example defined by a candle whose wick is consumed without the height of the flame being modified,

8 2847477

  as is particularly the case for short candles placed in

  suitable containers, of the type "tealight candles".

  It is of course conceivable to equip the device 3 with an electrically supplied heat source, to obtain the same result in terms of temperature constancy, however it is then necessary to have an electric circuit, this which limits the flexibility of use of said device. On the other hand, in order to accelerate the diffusion of heat and reach the melting temperature of the solid mixture in a minimum of time, said receptacle 5 as well as said chimney 6 are

  made of a conductive material, such as aluminum.

  According to a preferred embodiment of the device 3, the receptacle 5 is further completed with a cover 9, provided with a plurality of orifices 10 allowing the diffusion of the perfume in the atmosphere. This cover 9 not only plays an aesthetic role, but also makes it possible to avoid possible burns in contact with the

liquefied mixture.

  In the same spirit, the support 4 is moreover preferably coated with a covering which gives it both an aesthetic quality appearance and perfect thermal insulation, such as in particular wood. The present invention also relates to a product for the

  implementation of the method as described above.

  According to a first formulation possibility, such a product consists, by weight, of 30% of odorous substance, 50% of

  petrolatum, 10% white beeswax, and 10% stearin.

  Such a dosage gives rise to a product which is solid at ambient temperature, very easy to handle, reusable, and to which it is possible to give different forms, obtained for example by

  molding in suitable compartments.

  The melting point of such a product is 500C, which is optimally reached by placing this product substantially at 7cm

from a heat source.

9 2847477

  Once the latter is removed, the product gradually re-solidifies until it regains its shape and consistency.

  initial and is reusable several times in a row.

  Such a product has the advantage of being consumed very slowly and is therefore particularly economical for the user. According to another conceivable formulation, such a product can also consist, by weight, of 40% of odorous substance, 51% of

  petrolatum, 3% white beeswax, and 6% bentone gel.

  Here it will present the appearance of a slightly translucent paste, preferably packaged inside an airtight package

tube type.

  Such a formulation makes it possible to lower the melting point of the solid mixture to 400C and, consequently, to obtain a very rapid diffusion of the perfume, for a product preferably placed at 10

cm from a heat source.

  On the other hand, this formulation also has the advantage of avoiding the dispersion of the perfume and of allowing the user to control himself the quantity of product which he wishes to use at

every time.

  It is also possible to mix products containing different fragrances using a single device 3, in order to

  possibly personalize the diffused odor.

  Consequently, as is clear from all of the foregoing, the present invention makes it possible to solve the problems encountered with conventional type perfume diffusers, by using means that are at the same time economical, effective, aesthetic and

  guaranteeing perfect safety in use.

  Although the invention has been described in connection with a few particular embodiments, it is understood that it is in no way limited thereto and that it is possible to make various modifications to it in terms of shape, materials and combinations of these various elements, without departing from the frame and the spirit

of the invention.
