Description

Dispositif pour l'absorption d'une substance par voie buccale, son utilisation comme friandise, produit fortifiant, produit (phyto) harmaceutique et produit d' hygiène dentaire et procédé de fabrication d un tel dispositif.Device for the absorption of a substance by the oral route, its use as a treat, fortifying product, (phyto) harmaceutical product and dental hygiene product and method for manufacturing such a device.
Domaine de l' inventionField of the invention
L'invention se rapporte aux dispositifs et produits pour l'absorption de substances par voie buccale.The invention relates to devices and products for the absorption of substances by the oral route.
Elle concerne particulièrement des dispositifs et produits pour l'absorption buccale de substances par succion, léchage, mastication ou mâchonnement, telles que des substances gustatives, nutritives, thérapeutiques, phytotérapeutiques et/ou médicamenteuses.It particularly relates to devices and products for the oral absorption of substances by suction, licking, chewing or chewing, such as taste, nutritive, therapeutic, phytotherapeutic and / or medicinal substances.
Etat de la techniqueState of the art
Certains groupes de consommateurs recherchent des moyens garantissant l'absorption buccale contrôlée de substances gustatives, nutritives ou thérapeutiques.Certain consumer groups are looking for ways to guarantee controlled oral absorption of taste, nutritive or therapeutic substances.
Il existe en effet de nombreuses substances gustatives (par exemple des friandises) dont l'absorption buccale doit être contrôlée pour éviter des problèmes de santé. L' absorption buccale de substances thérapeutiques doit également être réglée, d'une part, pour obtenir l'effet thérapeutique désiré et, d'autre part, pour éviter l'apparition d'effets secondaires. Dans le cas de médicaments au goût désagréable, on recherche parfois également des moyens d'administration ludiques, notamment dans le cas d'enfants.There are indeed many taste substances (for example treats) whose oral absorption must be controlled to avoid health problems. The oral absorption of therapeutic substances must also be regulated, on the one hand, to obtain the desired therapeutic effect and, on the other hand, to avoid the appearance of side effects. In the case of drugs with an unpleasant taste, playful means of administration are sometimes also sought, particularly in the case of children.
L' absorption de substances nutritives par des personnes à faible appétit peut-être facilitée par l'usage de moyens ludiques. Il existe des essences végétales qui contiennent naturellement des substances gustatives agréables au goût. Le bois de réglisse et la canne à sucre constituent des exemples d'essences végétales de ce type. On connaît par ailleurs des bâtonnets en bois, enrobés de substances gustatives telles que de la crème pâtissière solidifiée par refroidissement ou des sirops. Ces bâtonnets enrobés ont le désavantage d'être difficiles à conserver, à emballer et à manutentionner. Dans le document FR-A-2 544 172, on propose une friandise en forme de bâtonnet, enrobé d'une pellicule en polyester susceptible de rétrécir par chauffage. Cette friandise connue présente l'avantage de posséder une bonne résistance mécanique. Sa fabrication est toutefois compliquée et elle implique la mise en œuvre d'une pellicule en polyester qu'il est parfois difficile d'enlever correctement sans détériorer le bâtonnet.The absorption of nutritive substances by people with low appetite can be facilitated by the use of playful means. There are vegetable essences which naturally contain taste substances pleasant to the taste. Licorice wood and sugar cane are examples of such plant species. Also known are wooden sticks, coated with taste substances such as pastry cream solidified by cooling or syrups. These coated sticks have the disadvantage of being difficult to store, package and handle. In document FR-A-2 544 172, a stick-shaped candy is proposed, coated with a polyester film capable of shrinking by heating. This known delicacy has the advantage of having good mechanical strength. Its manufacture is however complicated and it involves the implementation of a polyester film which it is sometimes difficult to remove correctly without damaging the stick.
Résumé de l'invention L'invention vise à fournir un dispositif nouveau pour l'absorption d'une substance par voie buccale, qui ne présente pas les inconvénients des moyens connus décrits plus haut.Summary of the invention The invention aims to provide a new device for absorbing a substance by the oral route, which does not have the drawbacks of the known means described above.
En conséquence, l'invention concerne un dispositif pour l'absorption d'une substance par voie buccale, ledit dispositif se caractérisant en ce qu' il comprend un support en bois imprégné artificiellement de ladite substance.Consequently, the invention relates to a device for absorbing a substance by the oral route, said device being characterized in that it comprises a wooden support artificially impregnated with said substance.
Dans le dispositif selon l'invention, le support en bois doit avoir une forme et des dimensions qui permettent son introduction dans la bouche d'un individu humain de constitution normale. La forme et les dimensions optimum peuvent varier selon que le dispositif est destiné à un enfant ou à un adulte. Nonobstant cette condition préalable, la forme et les dimensions du support en bois ne sont pas critiques. Le support en bois peut par exemple avoir une forme tabulaire, ovoïde, sphérique ou polyédrique. Dans une forme de réalisation particulière du dispositif selon l'invention, le support en bois est profilé pour pouvoir être manipulé facilement à la main (de préférence à une seule main) pour être introduit en bouche. Il peut avoir toute forme compatible avec une préhension et une manipulation facile.In the device according to the invention, the wooden support must have a shape and dimensions which allow its introduction into the mouth of a human individual of normal constitution. The optimum shape and dimensions may vary depending on whether the device is intended for a child or an adult. Notwithstanding this prerequisite, the shape and dimensions of the wooden support are not critical. The wooden support can for example have a tabular, ovoid, spherical or polyhedral shape. In a particular embodiment of the device according to the invention, the wooden support is profiled so that it can be easily handled by hand (preferably with one hand) to be introduced into the mouth. It can have any shape compatible with easy grip and handling.
Dans une forme de réalisation modifiée, le support en bois est fixé à un organe de préhension approprié. Dans cette forme de réalisation du dispositif selon l'invention, l'organe de préhension est distinct du support en bois et rapporté sur celui-ci. Il peut par exemple être en bois, en une résine synthétique, en carton, en verre ou en métal et il est spécialement adapté à la prise en main. En variante, il peut être fixé de manière amovible au support, de manière à pouvoir être récupéré. A cet effet, il peut par exemple être fixé au support en bois par vissage ou par emboîtement.In a modified embodiment, the wooden support is fixed to an appropriate gripping member. In this embodiment of the device according to the invention, the gripping member is separate from the wooden support and attached thereto. It can for example be made of wood, synthetic resin, cardboard, glass or metal and it is specially adapted for handling. Alternatively, it can be removably attached to the support, so that it can be recovered. For this purpose, it can for example be fixed to the wooden support by screwing or by interlocking.
Dans une forme de réalisation préférée du dispositif selon l'invention, le support en bois est un bâtonnet. Le bâtonnet possède avantageusement une longueur qui permette à un individu de le tenir en main à une extrémité, pour introduire l'autre extrémité dans la bouche. Le bâtonnet peut être rectiligne ou cintré et il peut avoir une section transversale circulaire, ovale ou polygonale, par exemple carrée, triangulaire, hexagonale ou octogonale. Les bâtonnets rectilignes de section carrée, triangulaire ou hexagonale présentent l'avantage de faciliter le stockage et la manutention. Des bâtonnets convenant bien ont une longueur supérieure à 2 cm et inférieure à 50 cm (de préférence comprise entre 4 cm et 30 cm) et une section transversale supérieure à 0,25 mm2 et inférieure à 4 cm2 (de préférence comprise 1 mm2 et 1 cm2). Les bâtonnets rectilignes présentant une longueur de 5 à 15 cm et une section transversale de 4 mm2 à 50 mm2 sont spécialement préférés.In a preferred embodiment of the device according to the invention, the wooden support is a stick. The stick advantageously has a length which allows an individual to hold it in hand at one end, to introduce the other end into the mouth. The rod can be straight or curved and it can have a circular, oval or polygonal cross section, for example square, triangular, hexagonal or octagonal. The rectilinear rods of square, triangular or hexagonal section have the advantage of facilitating storage and handling. Sticks that are well suited have a length of more than 2 cm and less than 50 cm (preferably between 4 cm and 30 cm) and a cross section greater than 0.25 mm 2 and less than 4 cm 2 (preferably between 1 mm 2 and 1 cm 2 ). The rectilinear rods having a length of 5 to 15 cm and a cross section of 4 mm 2 to 50 mm 2 are especially preferred.
Le bois du support doit appartenir à une essence comestible pour l'être humain ou rendue comestible par un traitement chimique ou physique approprié. On utilise avec avantage une essence de bois de faible résistance mécanique, pour permettre un mâchonnement ou une mastication par un individu de constitution normale, sans effort exagéré, inconfortable ou pénible. Le peuplier, le bouleau, le saule, l'érable, le hêtre et le tilleul sont des essences de bois qui conviennent bien et dont la sélection constitue dès lors une forme de réalisation avantageuse de l'invention. En variante, on peut sélectionner une essence qui présente naturellement des propriétés gustatives ou thérapeutiques naturelles, par exemple la canne à sucre ou le réglisse. Le bois peut être utilisé tel quel ou après avoir subi un traitement préalable pour en extraire une partie ou la totalité de ses propriétés naturelles. Le cas échéant, il convient d'éviter que ledit traitement préalable affecte la cellulose et la lignine du bois.The wood of the support must belong to an edible essence for humans or made edible by an appropriate chemical or physical treatment. A wood essence of low mechanical strength is advantageously used, to allow chewing or chewing by an individual of normal constitution, without exaggerated, uncomfortable or painful effort. Poplar, birch, willow, maple, beech and linden are wood species which are very suitable and whose selection therefore constitutes an advantageous embodiment of the invention. As a variant, an essence can be selected which naturally exhibits natural taste or therapeutic properties, for example sugar cane or licorice. The wood can be used as it is or after having undergone a preliminary treatment to extract some or all of its natural properties. If necessary, it should be avoided that said preliminary treatment affects cellulose and wood lignin.
La substance qui imprègne le support en bois doit être une substance comestible pour l'être humain. Elle peut être une substance hydrosoluble ou liposoluble et elle peut être sélectionnée parmi les substances gustatives, les substances aromatiques, les substances nutritives, les substances thérapeutiques, les substances phytothérapeutiques, les médicaments, les édulcorants et les colorants. Conformément à l'invention, la substance imprègne une partie substantielle du support en bois. On entend par cette expression que la substance est localisée entre ou dans les fibres cellulosiques du support en bois, à l'intérieur de celui-ci. La substance peut être répartie de manière sensiblement homogène dans le support en bois ou être répartie préferentiellement dans une partie du support. Par exemple, dans le cas d'un bâtonnet, l'imprégnation peut être limitée à la partie du bâtonnet destinée à être mise en bouche, l'extrémité destinée à être tenue en main n'étant pas imprégnée de la substance. En variante, on peut aussi répartir la substance davantage dans une zone superficielle du support en bois, plutôt que dans sa zone centrale. On préfère que la substance soit répartie de manière sensiblement uniforme dans le support en bois.The substance that permeates the wooden support must be an edible substance for humans. It can be a water-soluble or liposoluble substance and it can be selected from taste substances, aromatic substances, nutritive substances, therapeutic substances, phytotherapeutic substances, medicaments, sweeteners and colorings. According to the invention, the substance permeates a substantial part of the wooden support. By this expression is meant that the substance is located between or in the cellulosic fibers of the wooden support, inside the latter. The substance may be distributed in a substantially homogeneous manner in the wooden support or may be preferentially distributed in a part of the support. For example, in the case of a stick, the impregnation can be limited to the part of the stick intended to be placed in the mouth, the end intended to be held in hand not being impregnated with the substance. Alternatively, the substance can also be distributed more in a surface area of the wooden support, rather than in its central area. It is preferred that the substance is distributed in a substantially uniform manner in the wooden support.
Le support en bois peut éventuellement être recouvert d'une pellicule de la substance. Le cas échéant, la quantité de substance de la pellicule doit être minime par rapport à la quantité localisée entre ou dans les fibres du support en bois. En règle générale, elle est inférieure à 25 % (de préférence à 10 %) de la masse totale de substance imprégnant le support en bois et on préfère qu'elle n'excède pas 5 % de ladite masse totale. Dans une forme de réalisation préférée du dispositif selon l'invention, on évite expressément qu'une quantité substantielle de la substance recouvre le support en bois. Les dispositifs selon cette forme de réalisation de l'invention sont faciles à emballer et à manutentionner et ils évitent d' avoir les mains poisseuses pendant leur utilisation en bouche.The wooden support can optionally be covered with a film of the substance. If necessary, the quantity of substance of the film must be minimal compared to the quantity located between or in the fibers of the wooden support.

The invention therefore also relates to methods for the manufacture of devices in accordance with the invention, in particular candies, fortifying products, (phyto) therapeutic products and dental hygiene products in accordance with the invention.
Dans un premier procédé de fabrication selon l'invention, on met en œuvre un support en bois et on imprègne ledit support avec ladite substance.In a first manufacturing process according to the invention, a wooden support is used and said support is impregnated with said substance.
Dans le procédé selon l'invention, on peut utiliser toute technique connue et adéquate pour imprégner le support en bois et obtenir les propriétés d'imprégnation définies plus haut en relation avec le dispositif selon l'invention. Selon l'invention, l'imprégnation du support en bois est de préférence exécutée en phase liquide. A cet effet, selon un premier mode d'exécution du procédé selon l'invention, on traite le support en bois avec une solution aqueuse ou organique de la substance. Le traitement du support en bois avec la solution peut comprendre un badigeonnage ou une immersion. On préfère mettre en œuvre une immersion.In the method according to the invention, any known and adequate technique can be used to impregnate the wooden support and obtain the impregnation properties defined above in relation to the device according to the invention. According to the invention, the impregnation of the support wooden is preferably performed in the liquid phase. To this end, according to a first embodiment of the method according to the invention, the wooden support is treated with an aqueous or organic solution of the substance. Treatment of the wooden support with the solution may include brushing or immersion. We prefer to implement an immersion.
Dans un autre mode d'exécution du procédé selon 1' invention, spécialement destiné aux substances liposolubles, on réalise l'imprégnation dans un autoclave sous une atmosphère gazeuse maintenue dans un état supercritique de pression et de température. Dans cette forme de réalisation du procédé selon l'invention, l'atmosphère gazeuse est de préférence du dioxyde de carbone dont le point critique correspond à une température de 31 °C et une pression de 73,85 bar).In another embodiment of the process according to the invention, specially intended for liposoluble substances, the impregnation is carried out in an autoclave under a gaseous atmosphere maintained in a supercritical state of pressure and temperature. In this embodiment of the process according to the invention, the gaseous atmosphere is preferably carbon dioxide, the critical point of which corresponds to a temperature of 31 ° C. and a pressure of 73.85 bar).
Dans une variante du procédé selon l'invention, on soumet le support en bois, avant l'imprégnation, à un traitement d'extraction d'une partie au moins des matières hydrosolubles autres que la cellulose et la lignine, qu'il contient naturellement. Cette variante du procédé selon l'invention s'applique spécialement aux essences de bois qui contiennent naturellement des substances non comestibles ou présentant un goût désagréable ou qui sont dangereuses pour l'organisme. Ce traitement d'extraction peut comprendre un lavage à l'eau du support en bois ou une extraction par osmose ou encore une extraction par mise sous vide, qui sont des techniques bien connues. Dans un second procédé conforme à l'invention, on met en œuvre une pâte cellulosique, on additionne la substance à la pâte que l'on soumet ensuite à une filtration, on recueille un gâteau aqueux de la filtration que l'on soumet successivement à un essorage, à un chauffage et à un découpage.In a variant of the process according to the invention, the wooden support is subjected, before impregnation, to an extraction treatment of at least part of the water-soluble materials other than cellulose and lignin, which it naturally contains . This variant of the process according to the invention applies especially to wood species which naturally contain inedible substances or which have an unpleasant taste or which are dangerous for the organism. This extraction treatment may include washing the wooden support with water or an osmosis extraction or even a vacuum extraction, which are well known techniques. In a second process in accordance with the invention, a cellulosic paste is used, the substance is added to the paste which is then subjected to filtration, an aqueous cake of the filtration which is subjected successively to a spin, to heating and to cutting.
Les pâtes cellulosiques utilisées dans ce second procédé selon l'invention sont bien connues, notamment dans les techniques de fabrication du papier. De manière résumée, dans une technique appropriée à l'invention, on soumet des morceaux de bois (généralement des branches ou des troncs d'arbre) à un déchiquetage pour former des copeaux que l'on soumet à un lavage pour les débarrasser des substances minérales ou métalliques qu' ils pourraient contenir. On soumet ensuite les copeaux à une opération de défibrage. Cette opération peut consister en un défibrage mécanique ou un défibrage chimique. On préfère le défibrage mécanique. A l'issue du défibrage, on recueille une pâte cellulosique que l'on exploite dans le procédé selon l'invention.The cellulosic pulps used in this second process according to the invention are well known, in particular in the techniques of papermaking. To summarize, in a technique suitable for the invention, pieces of wood (generally branches or tree trunks) are subjected to shredding to form chips which are subjected to washing to remove them from the substances mineral or metallic that they could contain. The chips are then subjected to a defibration operation. This operation may consist of mechanical defibration or chemical defibration. Mechanical defibration is preferred. After defibration, a cellulose pulp is collected which is used in the process according to the invention.
Dans ce second procédé selon l'invention, la filtration peut avantageusement être effectuée sur une toile du type de celles habituellement utilisées dans les techniques papetières. La filtration s'opère à travers la toile. On peut accélérer celle-ci ou concentrer le gâteau en opérant une dépression sous la toile filtrante. L'essorage et le chauffage ont pour fonction de déshydrater le gâteau. A l'issue de la déshydratation, le gâteau est découpé aux dimensions du support en bois du dispositif selon l'invention. Il peut par exemple être découpé en bâtonnets. Les supports en bois (par exemple les bâtonnets) recueillis à l'issue de l'opération de découpage comprennent la substance dans leur masse. Ils constituent des dispositifs conformes à l'invention et sont prêts à l'emploi. Dans une variante recommandée du procédé, avant de découper le gâteau déshydraté, on soumet celui-ci à une compression pour lui conférer une résistance mécanique suffisante.In this second process according to the invention, the filtration can advantageously be carried out on a fabric of the type of those usually used in the papermaking techniques. Filtration takes place through the canvas. You can speed it up or concentrate the cake by operating a vacuum under the filter cloth. The function of spinning and heating is to dehydrate the cake. At the end of the dehydration, the cake is cut to the dimensions of the wooden support of the device according to the invention. It can for example be cut into sticks. The wooden supports (for example the sticks) collected at the end of the cutting operation include the substance in their mass. They constitute devices in accordance with the invention and are ready for use. In a recommended variant of the process, before cutting the dehydrated cake, subjects it to compression to give it sufficient mechanical strength.

La friandise comprend un bâtonnet cylindrique 1 en bois de peuplier dont les extrémités sont arrondies (une seule extrémité, désignée 4, étant représentée) . Le bâtonnet a un aspect tactile lisse. Conformément à l'invention, le bâtonnet 1 est imprégné d'une substance gustative (par exemple un mélange de sucre et d'extraits de fruits) sensiblement sur la totalité de son épaisseur et de sa longueur. Le bâtonnet porte une marque distinctive 3.Detailed description of a particular embodiment The figure shows a treat according to the invention. The candy includes a cylindrical stick 1 made of poplar wood whose ends are rounded (only one end, designated 4, being shown). The stick has a smooth tactile appearance. According to the invention, the stick 1 is impregnated with a taste substance (for example a mixture of sugar and fruit extracts) substantially over its entire thickness and length. The stick bears a distinctive mark 3.
La friandise est destinée à être tenue en main à son extrémité 4 et à être mâchonnée progressivement à partir de son autre extrémité 5. Le mâchonnement de la friandise a pour résultat de désunir les fibres cellulosiques 2 du bâtonnet en bois, qui libèrent de la sorte la substance gustative qu'elles emprisonnent, cette dernière passant dans la salive et au contact des papilles gustatives. The candy is intended to be held in the hand at its end 4 and to be chewed progressively from its other end 5. The chewing of the candy has the result of disuniting the cellulose fibers 2 of the wooden stick, which thus release the taste substance they trap, the latter passing through the saliva and in contact with the taste buds.
