Description

Nouvelle composition de paraffine et son utilisation dans des verrines ou autres contenants.New paraffin composition and its use in verrines or other containers.
La présente invention concerne une nouvelle composition de paraffine et son utilisation comme constituant principal pour des bougies à durée de combustion améliorée, disposées notamment dans une enceinte en verre ou autres contenants.The present invention relates to a new paraffin composition and its use as a main constituent for candles with improved burning time, arranged in particular in a glass enclosure or other containers.
On sait que la durée de combustion d'une composition de paraffine, par exemple une bougie, est un critère commercial important et qu'une demande est de plus en plus souvent exprimée, aussi bien pour une utilisation dans des édifices à caractère religieux que pour l'éclairage chez des particuliers, de disposer sur le marché de bougies présentant à la fois une faible vitesse de combustion, une combustion complète, harmonieuse et régulière, ainsi qu'une flamme éclairante et sans fumée. On sait aussi que, pour augmenter la durée de combustion d'une bougie, plusieurs solutions ont été envisagées, que ce soit par l'ajout d'accessoires, par exemple métalliques, à incorporer à la bougie, ou par des formulations spécifiques de la masse combustible. C'est à ce dernier aspect, qui tend à proposer une composition de paraffine particulière visant à améliorer la durée ainsi que la qualité de combustion, que s'intéresse la présente invention.It is known that the duration of combustion of a paraffin composition, for example a candle, is an important commercial criterion and that a demand is increasingly expressed, both for use in buildings of a religious nature and for lighting in private homes, to have candles on the market with both a low combustion speed, complete, harmonious and regular combustion, as well as an illuminating and smokeless flame. We also know that, to increase the burning time of a candle, several solutions have been envisaged, whether by adding accessories, for example metallic, to be incorporated into the candle, or by specific formulations of the combustible mass. It is this last aspect, which tends to propose a particular paraffin composition aiming to improve the duration as well as the quality of combustion, that the present invention is concerned with.
Pour que des bougies, ou tout autre article utilisant de la paraffine destinée à une combustion, puissent brûler pendant une longue période, il est connu que la composition de paraffine qui les constitue, éventuellement additionnée de différents additifs, doit avoir une vitesse de combustion relativement lente, c'est-à-dire une consommation ralentie en produits hydrocarbonés. De plus, cette combustion doit s'opérer d'une façon parfaitement régulière et homogène, afin que la surface supérieure de la bougie reste sensiblement plane et qu'elle évite de présenter, à sa partie haute, une surface concave, avec parfois un creux accentué au niveau de la mèche de la bougie. Dans ce dernier cas, en effet, la quantité d'air devenant insuffisante pour alimenter la flamme, il en résulte une combustion incomplète de la masse combustible, pouvant aller jusqu'à l'extinction de la flamme.In order for candles, or any other article using paraffin intended for combustion, to burn for a long period, it is known that the paraffin composition which constitutes them, possibly supplemented with various additives, must have a relatively rapid burning rate. slow, that is to say a slow consumption of hydrocarbon products. In addition, this combustion must take place in a perfectly regular and homogeneous manner, so that the upper surface of the spark plug remains substantially flat and that it avoids having, at its upper part, a concave surface, sometimes with a hollow. accentuated at the wick of the candle. In the latter case, in fact, the quantity of air becoming insufficient to supply the flame, this results in incomplete combustion of the combustible mass, which can go as far as extinguishing the flame.
On sait également que, dans la profession, l'on appelle couramment verrine des enceintes en verre, généralement transparent, ayant pour la plupart une forme cylindrique, mais dont la section transversale peut prendre une forme quelconque. A l'intérieur de ces verrines peuvent être disposées différentes matières et, notamment, une composition de paraffine, seule ou en mélange, qui, associée à une ou plusieurs mèches, est utilisée comme bougie éclairante. C'est à ce type d'application, qui n'a pas un caractère limitatif, que l'on se référera et que l'on désignera globalement sous l'appellation « verrine » dans la suite de la présente description.We also know that in the profession, we commonly call glass enclosures, generally transparent, mostly having a cylindrical shape, but the cross section of which can take any shape. Inside these verrines can be arranged different materials and, in particular, a paraffin composition, alone or in mixture, which, associated with one or more wicks, is used as a lighting candle. It is this type of application, which is not limiting, which will be referred to and which will be generally designated under the name "verrine" in the remainder of this description.
Le choix d'une composition de paraffine appropriée à une utilisation comme bougie éclairante dans une verrine est une opération complexe, car de nombreux paramètres doivent être pris en considération, tels que la qualité et la vitesse de combustion, cette dernière étant directement liée au point de fusion de la paraffine. L'objectif recherché est, en effet, d'obtenir une combustion complète, mais la plus lente possible de la masse combustible, y compris le long de la paroi du verre, avec une flamme éclairante et sans fumée, et ceci malgré la faible vitesse de combustion recherchée.Choosing a paraffin composition suitable for use as a lighting candle in a verrine is a complex operation, since many parameters must be taken into account, such as the quality and the rate of combustion, the latter being directly related to the point. of paraffin fusion. The objective sought is, in fact, to obtain a complete, but as slow as possible, combustion of the combustible mass, including along the wall of the glass, with an illuminating and smokeless flame, despite the low speed. of combustion sought.
Pour obtenir une fusion uniforme de l'ensemble de la surface supérieure de la bougie, et non seulement d'une portion de cette surface contiguë à la mèche, il est donc nécessaire d'abaisser de façon significative le point de fusion de la paraffine utilisée pour la fabrication de la bougie. Or, industriellement, on ne dispose généralement pas de paraffine répondant de façon parfaitement satisfaisante à cette condition et, pour abaisser encore davantage le point de fusion de la paraffine constituant essentiellement la bougie, il a été envisagé d'incorporer à cette paraffine de qualité commerciale, un composé combustible liquide. Ceci permet en effet de fondre la bougie suivant toute sa surface supérieure, même au contact de la paroi de verre de la verrine, ce qui n'est d'ailleurs possible que parce que la bougie est logée dans une enceinte en verre ou dans tout autre type de récipient analogue. En effet, si cette composition était utilisée isolément, par exemple sous forme d'un cierge, la composition liquide coulerait sur les faces latérales du cierge.To obtain a uniform melting of the entire upper surface of the candle, and not only of a portion of this surface contiguous to the wick, it is therefore necessary to significantly lower the melting point of the paraffin used for making the candle. However, industrially, there is generally no paraffin satisfactorily satisfying this condition and, to further lower the melting point of the paraffin essentially constituting the candle, it has been envisaged to incorporate this commercial grade paraffin , a liquid combustible compound. This makes it possible to melt the candle along its entire upper surface, even in contact with the glass wall of the verrine, which is moreover only possible because the candle is housed in a glass enclosure or in all another similar type of container. In fact, if this composition were used alone, for example in the form of a candle, the liquid composition would flow onto the lateral faces of the candle.
On obtient cependant ainsi une composition de bougie, qui brûle d'une manière régulière en produisant une flamme lumineuse, d'une hauteur satisfaisante, et sans fumées, qui ne risque pas de s'éteindre à la suite d'une alimentation en air insuffisante. Dans la pratique, on constate toutefois que la vitesse de combustion devient alors trop élevée, ce qui réduit la durée de vie de la bougie, et il s'avère nécessaire d'incorporer, dans la composition de paraffine, un additif apte à réduire sa vitesse de combustion, sans altérer pour autant ni l'aptitude de la bougie à fondre à basse température, ni la qualité de sa combustion, en particulier, l'absence de production de fumées noires.However, a candle composition is thus obtained, which burns in a regular manner producing a luminous flame, of a satisfactory height, and without fumes, which is not likely to extinguish following an insufficient air supply. . In practice, however, it is found that the combustion speed then becomes too high, which reduces the life of the candle, and it turns out to be necessary to incorporate, in the paraffin composition, an additive capable of reducing its combustion speed, without altering either the ability of the candle to melt at low temperature, nor the quality of its combustion, in particular, the absence of production of black smoke.
Un savant équilibre doit donc par conséquent être respecté entre la quantité du composé liquide combustible introduit dans la composition de paraffine de base et la teneur de cette composition en ralentis seur de combustion.A careful balance must therefore be respected between the quantity of the combustible liquid compound introduced into the base paraffin composition and the content of this composition in combustion retarder.
On ne sait pas aujourd'hui, dans la technique, fabriquer des verrines qui puissent brûler sans interruption pendant plus de 10 jours, et de préférence plus de 12 jours. Plus exactement, on ne dispose pas, sur le marché, de compositions de paraffine, seule ou en mélange, éventuellement avec des additifs, qui permettent d'atteindre directement les temps de combustion relativement longs réclamés par le consommateur. Des solutions ont été proposées pour ralentir la combustion comme dans FR-A-2 798 723 ou dans WO9923416, faisant appel à des artifices mécaniques logés, par exemple, au niveau de la mèche, mais sans pouvoir atteindre les temps de combustion cités précédemment.It is not known today, in the art, to make verrines which can burn continuously for more than 10 days, and preferably more than 12 days. More precisely, there are no paraffin compositions on the market, alone or in admixture, possibly with additives, which make it possible to directly achieve the relatively long combustion times demanded by the consumer. Solutions have been proposed to slow the combustion as in FR-A-2 798 723 or in WO9923416, using mechanical devices housed, for example, at the level of the wick, but without being able to reach the combustion times mentioned above.
C'est ce problème que se propose de résoudre la présente invention et elle vise à proposer dans ce but une composition de paraffine utilisable comme bougie dans des verrines, ou tout autre type de contenant, à section relativement large, qui se prête à une combustion très lente et parfaitement régulière, et dont la flamme provoque la fusion suivant la totalité de sa surface supérieure, même lorsque l'enceinte de verre a des dimensions transversales importantes, sans provoquer d'émission de fumées.It is this problem that the present invention proposes to solve and it aims to propose for this purpose a paraffin composition usable as a candle in verrines, or any other type of container, with a relatively large cross section, which lends itself to combustion. very slow and perfectly regular, and whose flame causes the fusion along its entire upper surface, even when the glass enclosure has large transverse dimensions, without causing emission of fumes.
L'invention a également pour but de proposer une telle composition de paraffine, qui, utilisée dans une verrine ou un récipient de grandes dimensions, a une durée de combustion largement supérieure à celle des compositions de la technique antérieure. L'invention a enfin pour but de proposer une composition de ce type, apte à brûler sur de longues périodes sans risque d'extinction et sans production de fumées. A cet effet, l'invention a pour objet une composition de paraffine utilisable comme bougie à longue durée de combustion, caractérisée en ce qu'elle comprend :The invention also aims to provide such a paraffin composition, which, used in a verrine or a container of large dimensions, has a burning time much greater than that of the compositions of the prior art.
