Description

COMPOSITION MICROGRANULEE ADSORBANTE ET ABSORBANTE DES ODEURS DE TABAC A USAGE DE CENDRIERS MICROGRANULATED ADSORBENT AND ABSORBENT COMPOSITION OF TOBACCO ODORS FOR ASHTRAY USE
L'invention est relative à une composition microgranulêe, àusage de cendriers, apte à éteindre quasi-instantanément les parties incandescentes des cigarettes et à réduire, voire éliminer, les odeurs dégagées par celles- ci en cours d'extinction (fumées) et une fois éteintes (tabac froid). Les compositions connues du genre en question sont décrites essentiel¬ lement dans les deux catégories de brevets suivants :The invention relates to a microgranular composition, with the use of ashtrays, capable of almost instantaneously extinguishing the incandescent parts of cigarettes and reducing, even eliminating, the odors given off by them being extinguished (smoke) and once extinct (cold tobacco). The known compositions of the genre in question are described essentially in the following two patent categories:
1) FR-2429822 (GUALANDI) qui décrit une composition désodorisante, à usage de cendriers, apte à répandre les vapeurs aptes à traiter l'air environnant. Elle comprend un constituant de base siliceux absorbant et une huile essen- tielle absorbée agissant comme masquant d'odeurs. Le procédé consiste à pulvériser des essences désodororisantes sur la totalité de la masse du constituant de base placée dans un mélangeur.1) FR-2429822 (GUALANDI) which describes a deodorizing composition, for use with ashtrays, capable of spreading the vapors capable of treating the surrounding air. It comprises an absorbent siliceous base constituent and an absorbed essential oil which acts as a mask for odors. The method consists in spraying deodorant essences on the entire mass of the basic constituent placed in a mixer.
Les brevets GB-2217603 (KITTY LITTLE) et EP-0250304 (POINTIER) appartiennent à la même catégorie. 1) JP-87177088 (NIPPON OIL SEAL) qui décrit une composition désodorisante, notamment à usage de cendriers, apte à retenir les odeurs spécifiques de tabac. Elle comprend un constituant de base siliceux et une solution de bétacyclodextrine absorbée agissant par absorption (par inclusion molécu¬ laire) des molécules des odeurs spécifiques de tabac. Dans les deux catégories de brevets, le constituant de base siliceuxPatents GB-2217603 (KITTY LITTLE) and EP-0250304 (POINTIER) belong to the same category. 1) JP-87177088 (NIPPON OIL SEAL) which describes a deodorizing composition, in particular for the use of ashtrays, capable of retaining the specific odors of tobacco. It comprises a siliceous base constituent and an absorbed betacyclodextrin solution which acts by absorption (by molecular inclusion) of molecules with specific tobacco odors. In both categories of patents, the siliceous base constituent
(microporeux) est utilisé comme support physique du constituant additionnel qui se présente toujours en solution acqueuse et qui est absorbé, selon le phénomène d'absorption des liquides propre aux corps siliceux, par les microporositês dudit support. Dans la première catégorie, le constituant additionnel agit comme masquant d'odeurs, autrement dit chacune de ses molécules est susceptible de venir se superposer, pour la neutraliser, à une molécule d'odeur de tabac. Dans la deuxième catégorie, le constituant additionnel agit par inclusion moléculaire, autrement dit chacune de ses molécules, creuse, est susceptible de "piéger" une molécule d'odeur de tabac.(microporous) is used as the physical support of the additional constituent which is always present in an aqueous solution and which is absorbed, according to the phenomenon of absorption of liquids specific to siliceous bodies, by the microporosites of said support. In the first category, the additional constituent acts as a mask for odors, in other words each of its molecules is capable of being superimposed, to neutralize it, on a molecule of tobacco smell. In the second category, the additional constituent acts by molecular inclusion, in other words each of its hollow molecules is capable of "trapping" a tobacco odor molecule.
Les compositions connues sus-mentionnées présentent les inconvénients particuliers suivants :The above-mentioned known compositions have the following particular drawbacks:
- le constituant de base siliceux n'est utilisé que pour ses propriétés d'absorption des liquides et non d'adsorption des gaz qui sont en outre- the siliceous base constituent is only used for its properties of absorption of liquids and not of adsorption of gases which are also
COPIE K CONFIRMATION réduites par le fait que les cavités des microporosités sont recouvertes de la solution de la substance additionnelle;COPY K CONFIRMATION reduced by the fact that the cavities of the microporosities are covered with the solution of the additional substance;
- les procédés utilisés sont sophistiqués car ils font intervenir des solutions à préparer, à pulvériser et à déshydrater (la composition) ce qui augmente de manière sensible le prix de revient du produit obtenu;- The processes used are sophisticated because they involve solutions to prepare, spray and dehydrate (the composition) which significantly increases the cost price of the product obtained;
- la masse volumique desdites compositions, en particulier pour les brevets GUALANDI et POINTIER qui utilisent du sable extra-siliceux, est supérieure à 1,5 Kg/dm3 ce qui accroît de façon sensible le prix de revient de la composition (prix de revient au m3, coûts de la manutention et du transport); - les additifs utilisés, à base d'huiles essentielles, ont pour effet de graisser les grains (diminution de la propriété coulante de la composition) et les cendriers (salissures) .- The density of said compositions, in particular for the GUALANDI and POINTIER patents which use extra-siliceous sand, is greater than 1.5 Kg / dm 3 which significantly increases the cost price of the composition (cost price per m 3 , handling and transport costs); - the additives used, based on essential oils, have the effect of greasing the grains (reduction in the flowable property of the composition) and the ashtrays (soiling).
L'invention vise donc à réaliser Une composition qui diminue, voire supprime, ces divers inconvénients. Elle concerne à cet effet une composition dont : a) le constituant de base a été choisi pour :The invention therefore aims to produce a composition which reduces or even eliminates these various drawbacks. To this end, it relates to a composition of which: a) the basic constituent has been chosen for:
- son aptitude à éteindre quasi-instantanément les cigarettes (de par sa structure poreuse et sa granulometrie);- its ability to quench cigarettes almost instantly (due to its porous structure and its particle size);
- son aptitude à adsorber, par réaction physico-chimique de surface, les molécules de gaz (de par sa granulomètrie et sa structure poreuse);- its ability to adsorb, by physicochemical surface reaction, gas molecules (due to its particle size and its porous structure);
- sa faible densité (réduction du prix de revient); b) le constituant additionnel a été choisi pour :- its low density (reduction of the cost price); b) the additional constituent has been chosen for:
- son aptitude à absorber, par inclusion moléculaire, les odeurs spécifiques de tabac (en complément du pouvoir d'adsorption du constituant de base); - son intervention dans de faibles quantités en poids ;- its ability to absorb, by molecular inclusion, specific tobacco odors (in addition to the adsorption power of the basic constituent); - its intervention in small quantities by weight;
- son indépendance à l'égard du constituant de base dont il n'altère pas ses propriérés intrinsèques.- its independence from the basic constituent, of which it does not alter its intrinsic properties.
Autrement dit, la composition selon l'invention combine les actions d'ad¬ sorption moléculaire des gaz du constituant de base et d'absorption molê- culaire des gaz du constituant additionnel.In other words, the composition according to the invention combines the actions of molecular sorption of the gases of the basic constituent and molecular absorption of the gases of the additional constituent.
Les recherches entreprises ont consisté à éliminer en particulier : a) comme constituant de base, les constituants siliceux qui ont une densité, une fois imprégnés et séchés, supérieure à 1,5 Kg/dm3; b) comme constituant additionnel, les solutions absorbées par la masse du constituant de base; c) les constituants qui consistent à traiter l'air environnant et non à retenir, dans la masse de la composition, les odeurs de tabac. La composition selon l'invention est du type utilisant un constituant de base siliceux microgranulé et un constituant additionnel contenant au moins une substance choisie pour ses qualités de rétension des molécules des odeurs spécifiques de tabac. Elle se caractérise essentiellement en ce qu'elle est constituée par un mélange dudit constituant de base siliceux microgranulé qui est choisi, dans sa nature et sa granulomètrie, pour être utilisé pour ses qualités de rétention, selon le phénomène d'adsorption des gaz, des molécules des odeurs spécifiques de tabac sur les parois des cavités dudit constituant de base; et en ce que le constituant additionnel, également microgranulé, qui est choisi, dans sa nature et dans sa forme physique, pour être utilisé pour ses qualités de rétention, selon le phénomène d'absorption des gaz par inclusion moléculaire, des odeurs spécifiques de tabac dans les cavités des molécules dudit constituant additionnel. Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un mode de réalisation préféré de l'invention donné à titre d'exemple non limitatif. Le constituant de base siliceux microgranulé est choisi pour être utilisé pour ses qualités de rétention, selon le phénomène d'adsorption des gaz, des molécules des odeurs spécifiques de tabac sur les parois des cavités dudit constituant de base.The research undertaken consisted in eliminating in particular: a) as a basic constituent, the siliceous constituents which have a density, once impregnated and dried, greater than 1.5 kg / dm 3 ; b) as additional constituent, the solutions absorbed by the mass of the basic constituent; c) the constituents which consist in treating the surrounding air and not in retaining, in the mass of the composition, the odors of tobacco. The composition according to the invention is of the type using a constituent of microgranulated siliceous base and an additional constituent containing at least one substance chosen for its qualities of retention of molecules of specific odors of tobacco. It is essentially characterized in that it is constituted by a mixture of said constituent of microgranulated siliceous base which is chosen, in its nature and its particle size, to be used for its retention qualities, according to the phenomenon of adsorption of gases, specific tobacco odor molecules on the walls of the cavities of said basic constituent; and in that the additional constituent, also microgranulated, which is chosen, in its nature and in its physical form, to be used for its retention qualities, according to the phenomenon of absorption of gases by molecular inclusion, specific odors of tobacco in the cavities of the molecules of said additional constituent. The characteristics and advantages of the invention will appear more clearly on reading the following detailed description of at least one preferred embodiment of the invention given by way of non-limiting example. The microgranulated siliceous base constituent is chosen to be used for its retention qualities, according to the phenomenon of adsorption of gases, molecules of specific odors of tobacco on the walls of the cavities of said basic constituent.
Le constituant de base siliceux peut être avantageusement de l'argile. Ledit constituant de base peut être avantageusement de l'attapulgite. L'argile et plus particulièrement l'attapulgite peuvent être calcinées pour accroître de façon sensible (plus de 50%) leur pouvoir d'adsorption des gaz.The siliceous base constituent can advantageously be clay. Said basic constituent can advantageously be attapulgite. The clay and more particularly the attapulgite can be calcined to appreciably increase (more than 50%) their power of adsorption of the gases.
Le constituant de base siliceux obtenu contient, par rapport à son poids total, 40 à 80% de SiÛ2 et de 10 à 30% d'un mélange d'oxydes métalliques comprenant AI2O3, Fe2θ3, CaO et MgO.The siliceous base constituent obtained contains, relative to its total weight, 40 to 80% of SiO2 and 10 to 30% of a mixture of metal oxides comprising Al2O3, Fe2θ3, CaO and MgO.
Le constituant additionnel, également microgranulé, contient au moins une substance qui est choisie pour être utilisée pour ses qualités de rétention, selon le phénomène d'absorption des gaz par inclusion moléculaire, des odeurs spécifiques de tabac dans les cavités des molécules dudit constitu- ant additionnel.The additional constituent, also microgranulated, contains at least one substance which is chosen to be used for its retention qualities, depending on the phenomenon of absorption of gases by molecular inclusion, specific odors of tobacco in the cavities of the molecules of said constituent. additional.
Le constituant additionnel peut être avantageusement de la bétacyclodextrine qui appartient à la famille des cyclodextrines (dévivés de l'amidon). Le constituant additionnel peut contenir, en addition, un masquant d'odeur de tabac.The additional constituent can advantageously be betacyclodextrin which belongs to the family of cyclodextrins (derived from starch). The additional constituent may contain, in addition, a tobacco odor masking agent.
La composition obtenue peut comporter, en addition, un colorant. Le constituant de base possède avantageusement une granulomètrie comprise entre 0,1 et 1 mm (meilleure adsorption).The composition obtained may comprise, in addition, a dye. The basic component advantageously has a particle size between 0.1 and 1 mm (better adsorption).
La composition obtenue possède avantageusement une masse volumique comprise entre 0,5 et 0,75 Kg/dm3 (réduction du prix de revient).The composition obtained advantageously has a density of between 0.5 and 0.75 Kg / dm 3 (reduction of the cost price).
Le constituant additionnel peut être constitué exclusivement par la subs¬ tance choisie pour ses qualités de rétention, par inclusion moléculaire, sous la forme microgranulée, en particulier par de la bétacyclodextrine.The additional constituent can be constituted exclusively by the substance chosen for its retention qualities, by molecular inclusion, in the microgranulated form, in particular by betacyclodextrin.
Le constituant additionnel peut être constitué par un mélange d'une solution de la substance choisie pour ses qualités de rétention et d'un constituant de même nature et de même granulomètrie que celles du constituant de base. Le constituant en question, servant de support à ladite substance en solution, intervient dans des proportions comprises entre 5 et 30% de la masse totale du constituant de base comprenant le support de même nature et de même granulomètrie.The additional constituent may consist of a mixture of a solution of the substance chosen for its retention qualities and of a constituent of the same nature and of the same particle size as those of the basic constituent. The constituent in question, serving as a support for said substance in solution, intervenes in proportions of between 5 and 30% of the total mass of the basic constituent comprising the support of the same nature and of the same particle size.
La substance choisie pour ses qualités de rétention,intervient dans des proportions comprises entre 0,2 et 10% du poids total de la composition. Le procédé de préparation de la composition selon l'invention,consiste: a) à calciner, dans une enceinte thermique, à une température de préférence comprise entre 600 et 900°C, le constituant de base microgranulé; b) à ajouter, audit constituant de base calciné, le constituant additionnel de manière à obtenir un mélange homogène entre les deuxdits constituants. Le constituant additionnel,qui est par exempledirectement la substance rete¬ nant les odeurs de tabac et qui se présente sous la forme microgranulée ou pulvérulente, est mélangé, par brassage, au constituant de base microgra¬ nulé. Le constituant additionnel peut être également obtenu par pulvérisation de la substance retenant les odeurs de tabac sur une base microgranulée, de même nature ou de nature différente de celle du constituant de base micro¬ granulé, pour être ensuite mélangé, par brassage, à ce dernier. La substance retenant les odeurs de tabac peut être avantageusement micro- pulvérisée directement sur 5 à 30% de la masse totale du constituant de base microgranulê résultant de la phase a) précédente, ladite masse concer¬ née par la pulvérisation étant ensuite mélangée, par brassage, aux 95 à 70% de la masse du constituant de base n'ayant pas subi l'opération de micro- pulvérisation.The substance chosen for its retention qualities, occurs in proportions of between 0.2 and 10% of the total weight of the composition. The process for preparing the composition according to the invention consists of: a) calcining, in a thermal enclosure, at a temperature preferably between 600 and 900 ° C, the basic constituent microgranulated; b) adding, to said calcined base constituent, the additional constituent so as to obtain a homogeneous mixture between the two said constituents. The additional constituent, which is for example directly the substance rete¬ ing odors of tobacco and which is in the microgranule or pulverulent form, is mixed, by stirring, with the basic constituent microgra¬ null. The additional constituent can also be obtained by spraying the substance retaining the odors of tobacco on a microgranular base, of the same nature or of a different nature from that of the basic constituent micro¬ granulate, to be then mixed, by stirring, with the latter . The substance retaining the odors of tobacco can advantageously be micro-sprayed directly on 5 to 30% of the total mass of the basic microgranular constituent resulting from phase a) above, said mass concerned by the spraying then being mixed, by stirring , to 95 to 70% of the mass of the basic constituent which has not undergone the micro- spray.
La substance retenant les odeurs de tabac peut intervenir avantageusement dans des proportions comprises entre 0,2 et 10% du poids total de la compo¬ sition. Un cycle de séchage accéléré peut éventuellement terminer le procédé si le taux d'humidité de la composition est supérieur à 10%. La substance retenant les odeurs de tabac, sous la forme microgranulée, peut être également mélangée au constituant de base sur lequel on a pulvé¬ risé, au préalable, une solution adhésive, partiellement de préférence, pour éviter le phénomène de ségrégation (différences de granulomètrie).The substance retaining the odors of tobacco can advantageously intervene in proportions of between 0.2 and 10% of the total weight of the composition. An accelerated drying cycle may possibly terminate the process if the moisture content of the composition is greater than 10%. The substance retaining the odors of tobacco, in the microgranular form, can also be mixed with the basic constituent on which an adhesive solution has been sprayed beforehand, partially preferably, to avoid the phenomenon of segregation (differences in particle size ).
Dans la composition ainsi élaborée, bien que les fonctions d'adsorption et d'aborption des odeurs de tabac sont réalisées à partir de deux constituants distincts, ces derniers coopèrent à un résultat d'ensemble nouveau et ori¬ ginal dans son efficacité (meilleur rendement du constituant additionnel). En outre, les qualités de coulage du constituant de base, qui constitue la masse principale de la composition, nei sont pratiquement pas modifiées par le constituant additionnel.In the composition thus produced, although the adsorption and absorption functions of tobacco odors are carried out from two distinct constituents, the latter cooperate in a new and original overall result in its effectiveness (better yield of the additional constituent). In addition, the casting qualities of the basic constituent, which constitutes the main mass of the composition, are practically not modified by the additional constituent.
Vouloir agir directement sur le constituant de base par des solutions de produits désodorisants, diminue de manière importante les propriétés adsor- bantes des produits en question. En outre, ils traitent davantage l'air ambiant que le mégot contenu dans le cendrier.Wanting to act directly on the basic constituent by solutions of deodorant products, significantly reduces the adsorbent properties of the products in question. In addition, they treat the ambient air more than the cigarette butt in the ashtray.
Les résultats obtenus par cette composition par son action sur les mégots, sont très supérieurs à ceux obtenus avec les compositions appartenant à l'état de la technique sus- entionnê (des tests comparatifs ont été réalisés). La composition ainsi obtenue est facile à élaborer et à conditionner.The results obtained by this composition by its action on cigarette butts are much higher than those obtained with the compositions belonging to the above-mentioned state of the art (comparative tests have been carried out). The composition thus obtained is easy to prepare and to package.
Elle permet de travailler à des fréquences élevées de fabrication et d'obte¬ nir des coûts relativement bas compatibles avec l'application concernée. Un tel produit, destiné aux cendriers domestiques et de voitures, doit être avant tout économique et efficace. Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits pour lesquels on pourra prévoir d'autres variantes :It makes it possible to work at high manufacturing frequencies and to obtain relatively low costs compatible with the application concerned. Such a product, intended for domestic ashtrays and cars, must be above all economical and effective. Of course, the invention is not limited to the embodiments described for which other variants can be provided:
- dans les argiles utilisées;- in the clays used;
- dans les constituants additionnels de même fonction;- in additional components with the same function;
- dans les proportions existant entre les différents constituants; sans pour cela sortir du cadre de l'invention. - in the proportions existing between the different constituents; without departing from the scope of the invention.
