Description

Domaine de l'inventionField of the invention

La présente invention concerne le domaine des articles pour la consommation par inhalation de substances solides ou pulvérulentes sèches généralement élaborées à partir de feuilles séchées ou de fleurs telles que par exemple le thym, la lavande, la sauge, l'eucalyptus, le pin, la mélisse, la menthe, le tabac ou encore le cannabis etc.The present invention relates to the field of articles for consumption by inhalation of dry solid or pulverulent substances generally made from dried leaves or flowers such as, for example, thyme, lavender, sage, eucalyptus, pine, lemon balm, mint, tobacco or cannabis etc.

La consommation se fait habituellement sous forme de cigarettes, joints, ou à l'aide d'une pipe, impliquant une combustion des plantes séchées, sous forme solide ou pulvérulente ou de vaporisateurs utilisant des techniques différentes.Consumption is usually in the form of cigarettes, joints, or using a pipe, involving combustion of dried plants, in solid or powder form or vaporizers using different techniques.

Ce type de consommation fonctionne par la combustion de la matière végétale (ou pyrolyse) produisant une fumée qui est inhalée par l'utilisateur. La température de la braise varie entre 400°C et 900°C entrainant la formation de nombreux produits toxiques et détruisant près de la moitié, des principes actifs de la plante. La pyrolyse produit des réactions chimiques transformant certains constituants de la plante en résidus de combustion et/ou goudrons, très nocifs, formés par un mélange de plusieurs centaines de substances chimiques. Parmi ces substances, plusieurs dizaines se sont avérées cancérigènes (hydrocarbures polycycliques aromatiques, nitrosamines)This type of consumption works by burning plant matter (or pyrolysis) producing smoke that is inhaled by the user. The temperature of the embers varies between 400°C and 900°C causing the formation of many toxic products and destroying almost half of the active ingredients of the plant. Pyrolysis produces chemical reactions that transform certain constituents of the plant into very harmful combustion residues and/or tars, formed by a mixture of several hundred chemical substances. Among these substances, several dozen have proven to be carcinogenic (polycyclic aromatic hydrocarbons, nitrosamines)

Pour éviter une consommation par combustion de plantes séchées, plusieurs alternatives sont actuellement connues de l'art antérieur.To avoid consumption by combustion of dried plants, several alternatives are currently known from the prior art.

Il existe notamment un dispositif permettant la consommation de plantes avec une pipe à eau, aussi appelé Narguilé, bang ou Chicha. Ce dispositif permet la consommation de plantes en utilisant de l'eau pour former une fumée dense. Lorsque l'utilisateur aspire, de l'air chaud passe à travers la mélasse, puis le tube qui l'achemine jusqu'à l'eau avant de remplir le pot dans lequel il est aspiré par l'utilisateur. Le tabac pour les narguilés est très semblable à ceux utilisés pour les pipes traditionnelles, mais extrêmement épicé et mélangé avec du glucose alcoolique liquide (mélasse), une substance très dense et collante qui a deux buts : retarder la combustion autant que possible et adoucir la fumée ainsi formée. Le produit consommé est chauffé ce qui conduit à une combustion incomplète ; ceci diffère d'une cigarette dans laquelle le produit est brulé. Les températures moins élevées de ce dispositif entrainent la formation de moins de composés nocifs. Toutefois, le volume d'air généré par l'utilisation d'eau ainsi que le temps de consommation plus long entrainent une toxicité plus grande qu'avec une cigarette pour l'utilisateur.There is in particular a device allowing the consumption of plants with a water pipe, also called Hookah, bong or Chicha. This device allows the consumption of plants by using water to form a dense smoke. When the user inhales, hot air passes through the molasses, then the tube which conveys it to the water before filling the pot into which it is sucked by the user. The tobacco for hookahs is very similar to that used for traditional pipes, but extremely spicy and mixed with glucose liquid alcoholic (molasses), a very dense and sticky substance which has two purposes: to delay combustion as much as possible and to sweeten the smoke thus formed. The consumed product is heated which leads to incomplete combustion; this differs from a cigarette in which the product is burned. The lower temperatures of this device lead to the formation of fewer harmful compounds. However, the volume of air generated by the use of water as well as the longer consumption time lead to greater toxicity than with a cigarette for the user.

L'article « Systematic Review and Meta-Analysis of Inhaled Toxicants from Waterpipe and Cigarette Smoking » - Brian A Primack et al. Janvier/février 2016 , démontre que la consommation sous forme de pipe à eau expose les utilisateurs à des volumes de fumée plus importants et à des niveaux plus élevés de substances toxiques par rapport à une consommation de tabac sous forme de cigarette ou de joint.The article "Systematic Review and Meta-Analysis of Inhaled Toxicants from Waterpipe and Cigarette Smoking" - Brian A Primack et al. January/February 2016 , demonstrates that smoking in the form of a waterpipe exposes users to greater volumes of smoke and higher levels of toxic substances compared to smoking in the form of a cigarette or a joint.

Une seconde alternative à la combustion de matière végétale est la consommation par inhalation de vapeur de substances sèches solides ou pulvérulentes (phyto-inhalation). Cette méthode consiste en une vaporisation des composants contenus dans les plantes séchées. Le produit est chauffé dans un dispositif et l'utilisateur inhale les principes actifs libérés. Contrairement aux modes de consommations par combustion, ce procédé ne produit pas de fumée mais une vapeur sans sous-produits toxiques qui contient uniquement les principes actifs. Toutefois, la vaporisation des composants peut amener à la désagrégation des plantes séchées en petites particules. Lorsqu'elles sont aspirées, ces particules toxiques peuvent remonter dans le conduit d'aspiration et brûler les voies respiratoires de l'utilisateur. Les dispositifs que l'art antérieur propose ne comportent aucune solution efficace pour empêcher les particules de remonter dans le conduit d'aspiration.A second alternative to the combustion of vegetable matter is the consumption by vapor inhalation of dry solid or powdery substances (phyto-inhalation). This method consists of vaporizing the components contained in the dried plants. The product is heated in a device and the user inhales the released active ingredients. Contrary to the modes of consumption by combustion, this process does not produce smoke but a vapor without toxic by-products which contains only the active ingredients. However, vaporization of the components can lead to the disintegration of the dried plants into small particles. When aspirated, these toxic particles can travel up the suction duct and burn the user's airways. The devices that the prior art proposes do not include any effective solution for preventing the particles from rising in the suction duct.

Le problème technique à résoudre est de proposer un dispositif permettant de prévenir les différents risques sanitaires liés à la consommation de plantes séchées solides ou pulvérulentes en évitant la combustion de plantes séchées et en limitant l'aspiration des particules produites lors de la mise en œuvre du procédé pouvant brûler les voies respiratoires de l'utilisateur.The technical problem to be solved is to propose a device making it possible to prevent the various health risks associated with the consumption of solid or pulverulent dried plants by avoiding the combustion of dried plants and by limiting the aspiration of the particles produced during the implementation of the process that can burn the user's airways.

Inconvénients de l'art antérieurDisadvantages of the prior art

Les solutions de l'art antérieur ne sont pas totalement satisfaisantes. En effet, les solutions de type cigarette, joints ou pipes n'évitent pas la combustion de plantes séchées, avec les inconvénients déjà mentionnés. Au contraire, les documents de l'art antérieur concernent la combustion des plantes et ne prévoient aucune sécurité pour éviter l'inhalation des particules nocives, tout en permettant une fabrication simple et économique.The solutions of the prior art are not completely satisfactory. Indeed, solutions of the cigarette, joint or pipe type do not avoid the combustion of dried plants, with the drawbacks already mentioned. On the contrary, the documents of the prior art relate to the combustion of plants and do not provide any security to avoid the inhalation of harmful particles, while allowing simple and economical manufacture.

Les solutions de type narguilé ou « chicha », de par leur combustion dite "incomplète" conduisent à une consommation d'un volume très important de fumée et n'excluent pas complétement la formation de résidus toxiques De plus, ce dispositif ne permet pas de consommer des plantes séchées solides ou pulvérulentes proprement dit puisque le produit doit nécessairement être mélangé à du glucose alcoolique liquide afin d'obtenir un mélange de type mélasse.Hookah or “shisha” type solutions, due to their so-called “incomplete” combustion, lead to the consumption of a very large volume of smoke and do not completely exclude the formation of toxic residues. Moreover, this device does not make it possible to consume solid or pulverulent dried plants as such, since the product must necessarily be mixed with liquid alcoholic glucose in order to obtain a molasses-like mixture.

Les dispositifs utilisant des méthodes de vaporisation par sublimation de plantes séchées ne proposent pas de solution permettant de limiter les particules issues de la désagrégation des plantes séchées utilisées.The devices using methods of vaporization by sublimation of dried plants do not offer a solution making it possible to limit the particles resulting from the disintegration of the dried plants used.

Avantages de l'inventionAdvantages of the invention

La présente invention répond au problème technique en proposant un dispositif de consommation par vaporisation à partir de substances sèches ou pulvérulentes amélioré et innovant. Ce dispositif, fonctionne grâce à une réaction de sublimation consistant à vaporiser les composés contenus dans la substance sèche ou pulvérulente. De manière tout à fait innovante, le dispositif adresse le problème de la combustion secondaire. Bien que le dispositif fonctionne par sublimation, une utilisation intensive de celui-ci peut finir par entrainer une combustion de la substance utilisée. En effet, lors d'une utilisation intensive de dispositif de vaporisation en verre de type « ampoule », des particules chaudes pouvant provenir de la substance elle-même ou bien de résidus formés par une combustion de la substance utilisée peuvent remonter dans le conduit d'inhalation. Ces particules peuvent alors être ingérées et brûler les voies respiratoires de l'utilisateur. On parle alors de résidus de combustion.The present invention responds to the technical problem by proposing an improved and innovative device for consumption by vaporization using dry or powdery substances. This device works thanks to a sublimation reaction consisting in vaporizing the compounds contained in the dry or powdery substance. In a completely innovative way, the device addresses the problem of secondary combustion. Although the device works by sublimation, intensive use of it can end up causing combustion of the substance used. In fact, during intensive use of the "bulb" type glass vaporization device, hot particles that may come from the substance itself or from residues formed by combustion of the substance used may rise in the duct of the vaporizer. 'inhalation. These particles can then be ingested and burn the user's airways. We then speak of combustion residues.

Afin de résoudre les effets néfastes pour l'utilisateur des résidus de combustion, l'invention comporte un filtre spécifique permettant de prévenir l'inhalation de ces particules toxiques. Le filtre du dispositif permet de garantir à l'utilisateur un mode de consommation sans aucun risque de brûlure de ses voies respiratoires. Positionné dans le conduit d'inhalation, il retient les particules sans bloquer le passage de la vapeur. L'utilisateur continue à avoir un débit d'inhalation satisfaisant, puisque le filtre ne bloque pas le passage de l'air et de la vapeur tout en évitant l'ingestion de particules. De manière avantageuse, le filtre est composé de fil d 'acier inoxydable compatible alimentaire afin de garantir une innocuité à l'utilisateur, c'est-à-dire qu'aucun composé toxique ne peut s'échapper du filtre lors de l'inhalation. Enfin, son maillage étroit permet de retenir les particules. Celle-ci sont généralement comprises entre 150 et 250 micromètres.In order to solve the harmful effects for the user of the combustion residues, the invention comprises a specific filter making it possible to prevent the inhalation of these toxic particles. The filter of the device makes it possible to guarantee the user a mode of consumption without any risk of burning his respiratory tract. Positioned in the inhalation duct, it retains the particles without blocking the passage of steam. The user continues to have a satisfactory inhalation rate, since the filter does not block the passage of air and vapor while avoiding the ingestion of particles. Advantageously, the filter is made of food-grade stainless steel wire in order to guarantee harmlessness to the user, that is to say that no toxic compound can escape from the filter during inhalation. . Finally, its narrow mesh allows particles to be retained. These are generally between 150 and 250 micrometers.

Un autre avantage de l'invention est que le dispositif comprend un évent dans son hémisphère inférieur. Ainsi, l'air rentre plus facilement dans le dispositif pour permettre la formation de vapeur. Cet évent peut être obturé par l'utilisateur avec son doigt afin de créer un appel d'air plus ou moins important et ainsi régler l'intensité du débit de vapeur.Another advantage of the invention is that the device includes a vent in its lower hemisphere. Thus, the air enters the device more easily to allow the formation of steam. This vent can be blocked by the user with his finger in order to create a greater or lesser air intake and thus adjust the intensity of the steam flow.

L'élément filtrant (40) est constitué par un paquet cylindrique de fil d'acier tricoté d'une section correspondant à la section intérieure du conduit d'inhalation (30), par exemple de 10.95 mm. La hauteur de l'élément filtrant est d'environ 2.5 à 6 millimètres. L'élément filtrant (40) est formé par compression dans une presse à emboutir avec l'aide d'un outillage de compression à empreintes de type poinçon / matrice. Le fil est un fil d'acier inoxydable de type Inox alimentaire, constitué par un alliage comprenant les éléments suivants : carbone, chrome, silicium, manganèse, phosphore, soufre et Nickel. Le fil présente une section de 180 micromètres avec une tolérance de 15 micromètres. Il est formé par un fil tricoté, découpé, roulé et compressé en deux étapes. Il permet de filtrer des particules dont la taille est comprise entre 150 et 250 micromètres. Le fil est maillé et replié pour former des mailles comprimées, de façon à éviter la formation d'aspérités pointues.The filtering element (40) consists of a cylindrical package of knitted steel wire with a section corresponding to the internal section of the inhalation conduit (30), for example 10.95 mm. The height of the filter element is about 2.5 to 6 millimeters. The filter element (40) is formed by compression in a stamping press with the aid of punch/die type indentation compression tooling.
