Abstract

The method involves directly rolling a sheet without using a cylindrical support, and forming a cylindrical rigid case (9) with tubes (2, 3), where the tubes are formed by cutting a heatweldable hollow plastic rod, and ends (4, 5) of the tubes are closed by heat sealing. The rolled sheet is inserted in the tubes of the rigid case, where the closed ends of the tubes are arranged at opposite ends of the case when the tubes are assembled. The case with the sheet is packaged in a flexible package made of aluminum foil. An independent claim is also included for a sheet package comprising a rigid case.

Description

L'invention concerne un procédé de conditionnement de feuille(s), formées dans un matériau incorporant du tabac, et le conditionnement ainsi réalisé.The invention relates to a method of packaging sheet (s), formed in a material incorporating tobacco, and the packaging thus produced.

De telles feuilles, formées dans un matériau incorporant du tabac, sont connues par les consommateurs de tabac.Such sheets, formed in a material incorporating tobacco, are known to tobacco users.

Ces feuilles permettent aux consommateurs de fabriquer, eux-mêmes, leur cigare, en remplissant les feuilles avec un mélange de tabac qu'ils auront préalablement choisi ; puis, de rouler ledit mélange dans la feuille, afin de former un cigare. Ainsi, ces feuilles permettent d'adapter les cigares, en fonction des goûts du consommateur.These leaves allow consumers to make their own cigar by filling the leaves with a mixture of tobacco they have previously chosen; then roll the mixture into the sheet to form a cigar. Thus, these sheets make it possible to adapt the cigars, according to the tastes of the consumer.

En outre, ces feuilles présentent des qualités gustatives supérieures aux feuilles de papier à rouler classiques et peuvent, dans certain cas, contenir des arômes additionnels.In addition, these sheets have taste qualities superior to conventional paper rolls and may, in some cases, contain additional flavors.

Toutefois, les feuilles formées dans un matériau incorporant du tabac, appelées également « blunt », sont plus fragiles que les feuilles de papier à rouler classiques. En effet, la présence de tabac rend les feuilles plus friables. Ce défaut est d'autant plus aggravé que les feuilles ne sont pas conditionnées de façon hermétique à l'humidité. En effet, la mise à l'air libre des feuilles, pendant quelques minutes, provoque leur assèchement et celles-ci deviennent, alors, très fragiles et, par conséquent, inutilisables. En outre, l'exposition des feuilles à l'air libre détériore le goût et les arômes des feuilles.However, the sheets formed in a material incorporating tobacco, also called "blunt", are more fragile than conventional rolling paper sheets. Indeed, the presence of tobacco makes the leaves more friable. This defect is all the more aggravated that the leaves are not packaged hermetically to moisture. Indeed, the venting of the leaves, for a few minutes, causes their drying and they become, then, very fragile and, therefore, unusable. In addition, exposure of the leaves to the open air deteriorates the taste and aromas of the leaves.

Ainsi, la qualité du conditionnement de ces feuilles est-il critique afin de réduire les inconvénients mentionnés ci-dessus.Thus, the quality of the packaging of these sheets is critical to reduce the disadvantages mentioned above.

Dans l'art antérieur, des conditionnements de ce type de feuilles sont connus et décrits dans le brevet américain US 6 742 525 et dans les demandes de brevets US 20050072439 et US 20050072437 .In the prior art, packages of this type of sheet are known and described in US Pat. US 6,742,525 and in patent applications US 20050072439 and US 20050072437 .

Le brevet US 6 742 525 propose d'enrouler la feuille sur un tube afin de rigidifier l'ensemble, puis d'emballer le tube et la feuille dans un emballage souple hermétique. Toutefois, cette solution n'est pas entièrement satisfaisante car elle nécessite l'utilisation d'un tube intérieur pour garantir la rigidité du conditionnement. En outre, lorsque l'emballe souple est ouvert, l'herméticité de l'emballage n'est plus assuré.The patent US 6,742,525 proposes to wind the sheet on a tube in order to stiffen the assembly, then to pack the tube and the sheet in a hermetic flexible packaging. However, this solution is not entirely satisfactory because it requires the use of an inner tube to ensure the rigidity of the packaging. In addition, when the flexible package is opened, the hermeticity of the packaging is no longer assured.

La demande de brevet US 20050072437 propose d'enrouler la feuille de tabac autour d'un cigare puis de conditionner l'ensemble ainsi obtenu dans un emballage souple ; l'emballage souple étant ensuite disposé dans un boîtier rigide. Toutefois, cette solution est onéreuse et relativement complexe car elle nécessite de nombreux éléments d'emballage et la présence d'un cigare.The patent application US 20050072437 proposes to wrap the tobacco leaf around a cigar and then package the resulting assembly in a flexible package; the flexible package is then disposed in a rigid housing. However, this solution is expensive and relatively complex because it requires many packaging elements and the presence of a cigar.

La demande de brevet US 20050072439 propose de disposer les feuilles formées dans un matériau incorporant du tabac sur des feuilles d'emballage souple puis d'enrouler l'ensemble autour d'un rouleau cylindrique. Le rouleau peut ensuite être retiré et les objets ainsi obtenus sont conditionnés, éventuellement par lot, dans un récipient pour être acheminés vers les consommateurs. Toutefois, cette solution possède des inconvénients. En effet, cette solution nécessite l'utilisation d'un rouleau cylindrique. En outre, lorsque le récipient est ouvert, la feuille d'emballage n'est pas suffisamment hermétique pour garantir la conservation des propriétés initiales de la feuille et pas suffisamment rigide pour garantir son intégrité physique. Ainsi, lorsque le récipient est ouvert, les feuilles de tabac s'assèchent et se dégradent rapidementThe patent application US 20050072439 proposes to arrange the sheets formed in a material incorporating tobacco on flexible packaging sheets and then to wind the assembly around a cylindrical roller. The roll can then be removed and the objects thus obtained are packaged, possibly batchwise, in a container to be conveyed to consumers. However, this solution has disadvantages. Indeed, this solution requires the use of a cylindrical roller. In addition, when the container is open, the packaging sheet is not sufficiently sealed to ensure the preservation of the initial properties of the sheet and not sufficiently rigid to ensure its physical integrity. Thus, when the container is opened, the tobacco leaves dry and degrade quickly

L'invention vise à remédier à ces problèmes en proposant un procédé de conditionnement de feuilles du type formées dans un matériau incorporant du tabac qui soit simple, peu onéreux et permet de garantir les propriétés gustatives et l'intégrité physique desdites feuilles.The invention aims to remedy these problems by proposing a method of packaging sheets of the type formed in a material incorporating tobacco that is simple, inexpensive and ensures the taste properties and physical integrity of said sheets.

À cet effet, et selon un premier aspect, l'invention propose un procédé selon la revendication 1.For this purpose, and according to a first aspect, the invention provides a method according to claim 1.

Ainsi, le procédé est relativement simple et nécessite peu d'étapes de conditionnement car la feuille est directement enroulée sur elle-même.Thus, the process is relatively simple and requires few conditioning steps because the sheet is directly wound on itself.

Par ailleurs, l'étui assure à la fois la rigidité du conditionnement et son herméticité ce qui garantit les propriétés et l'intégrité de la feuille ainsi conditionnée. En outre, un tel étui permet un conditionnement relativement facile pour les opérateurs.Moreover, the case ensures both the rigidity of the packaging and its hermeticity which guarantees the properties and integrity of the sheet thus packaged. In addition, such a case allows relatively easy packaging for operators.

La fabrication des tubes est réalisée par découpage d'une tige plastique creuse en matériau thermo-scellable et obturation par thermo scellage d'une extrémité du tube. Ainsi, la fabrication de l'étui est aisée et peu coûteuse et peut être réalisée directement sur le site de conditionnement.The tubes are manufactured by cutting a hollow plastic rod made of thermo-sealable material and sealing by heat-sealing one end of the tube. Thus, the manufacture of the case is easy and inexpensive and can be performed directly on the packaging site.

Dans un mode de réalisation, les tubes sont réalisés en polypropylène ou en polyéthylène.In one embodiment, the tubes are made of polypropylene or polyethylene.

Chaque tube est découpé à une longueur comprise entre 75 et 95 % de la longueur de la feuille. Ainsi, les tubes se recouvrent sur une distance importante afin de conférer une bonne herméticité à l'étui ainsi réalisé.Each tube is cut to a length of between 75 and 95% of the length of the sheet. Thus, the tubes overlap over a significant distance to provide a good hermeticity to the case thus produced.

Le procédé comprend une étape d'installation de moyens amovibles de fixation des tubes l'un sur l'autre. Cette caractéristique permet de garantir que les tubes ne se désolidarisent pas.The method comprises a step of installing removable means for fixing the tubes to one another. This characteristic makes it possible to guarantee that the tubes do not dissociate.

Avantageusement, le procédé comprend en outre une étape de conditionnement d'au moins un étui comportant une feuille dans un emballage souple. Ainsi, l'emballage souple permet d'améliorer l'étanchéité du conditionnement et permet l'inscription d'informations sur le produit.Advantageously, the method further comprises a step of packaging at least one case comprising a sheet in a flexible package. Thus, the flexible packaging improves the sealing of the packaging and allows the registration of product information.

Dans un mode de réalisation de l'invention, une pluralité d'étuis est conditionnée dans l'emballage souple.In one embodiment of the invention, a plurality of cases are packaged in the flexible package.

On remarquera que l'emballage souple peut contenir une pluralité d'étuis sans nuire à la qualité des feuilles. En effet, selon l'invention, lorsque l'emballage souple est ouvert, les feuilles ne se dégradent pas en raison de l'herméticité de l'étui.It will be appreciated that the flexible package may contain a plurality of cases without affecting the quality of the sheets. Indeed, according to the invention, when the flexible packaging is open, the leaves do not degrade due to the hermeticity of the case.

Avantageusement, l'emballage souple est hermétique afin de garantir la fraîcheur de la feuille. Dans un mode de réalisation, l'emballage est réalisé dans un matériau composite comprenant une feuille d'aluminium.Advantageously, the flexible packaging is hermetic to guarantee the freshness of the sheet. In one embodiment, the package is made of a composite material comprising an aluminum foil.

Selon un second aspect, l'invention concerne un conditionnement d'au moins une feuille formée dans un matériau incorporant du tabac selon la revendication 8.According to a second aspect, the invention relates to a packaging of at least one sheet formed in a material incorporating tobacco according to claim 8.

Avantageusement, le conditionnement comprend un emballage souple hermétique dans lequel est disposé au moins un étui rigide cylindrique comprenant une feuille.Advantageously, the packaging comprises a flexible hermetic packaging in which is disposed at least one cylindrical rigid case comprising a sheet.

D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit, faite en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue schématique en perspective d'une feuille enroulée ;
  • la figure 2 est une vue schématique d'un étui rigide cylindrique composé de deux tubes emboîtables, et fermées à leur extrémité opposée.
  • la figure 3 est une vue schématique d'un conditionnement réalisé selon un mode de réalisation de l'invention, lorsque la feuille enroulée est insérée dans l'étui ; et
  • la figure 4 est une vue schématique d'un conditionnement réalisé selon un mode de réalisation de l'invention, deux étuis comportant une feuille étant conditionnés dans un emballage hermétique ; et
  • la figure 5 est une vue schématique d'un conditionnement réalisé selon un autre mode de réalisation, trois étuis étant conditionnés dans un emballage hermétique.
Other objects and advantages of the invention will become apparent from the following description, made with reference to the appended drawings, in which:
  • the figure 1 is a schematic perspective view of a rolled sheet;
  • the figure 2 is a schematic view of a cylindrical rigid case composed of two nestable tubes, and closed at their opposite end.
  • the figure 3 is a schematic view of a packaging made according to one embodiment of the invention, when the wrapped sheet is inserted into the case; and
  • the figure 4 is a schematic view of a packaging made according to one embodiment of the invention, two cases comprising a sheet being packaged in an airtight package; and
  • the figure 5 is a schematic view of a packaging made according to another embodiment, three cases being packaged in a hermetic package.

La figure 1 représente une feuille 1 enroulée sur elle-même. Selon l'invention, cette feuille 1 est réalisée avec un matériau incorporant du tabac. La feuille 1 peut être une feuille de tabac naturel ou une feuille composite dont la composition est sensiblement la suivante : 50 à 65 % de tabac, 30 à 50 de papier et 3 à 10 % d'arômes naturels ou artificiels (pomme, fraise, vanille, whisky...). La feuille 1 est pourvue sur un de ses côtés latéraux d'une bande de collage, non représentée.The figure 1 represents a sheet 1 wound on itself. According to the invention, this sheet 1 is made of a material incorporating tobacco. The sheet 1 may be a natural tobacco leaf or a composite sheet whose composition is substantially as follows: 50 to 65% of tobacco, 30 to 50 of paper and 3 to 10% of natural or artificial flavors (apple, strawberry, vanilla, whiskey ...). The sheet 1 is provided on one of its lateral sides with a bonding strip, not shown.

On notera que, selon l'invention, l'expression « enroulée sur elle-même » désigne une feuille 1 enroulée sans l'aide d'un support cylindrique intérieur.Note that, according to the invention, the term "wound on itself" means a sheet 1 wound without the aid of an inner cylindrical support.

La figure 2 représente un étui 9 rigide cylindrique permettant de recevoir la feuille 1 de tabac enroulée. L'étui 9 est rigide et composé d'un assemblage de deux tubes 2, 3 fermés à une de leurs extrémités 4, 5. Les tubes 2, 3 sont emboîtables l'un dans l'autre. À cet effet, un premier tube 2 possède un diamètre légèrement inférieur au second tube 3 afin de permettre son introduction à l'intérieur du second 3. Avantageusement, la différence de diamètre entre le premier 2 et le second tube 3 est faible, inférieure à 1 mm, afin de conférer à l'étui 9 une bonne étanchéité.The figure 2 represents a cylindrical rigid case 9 for receiving the sheet 1 of coiled tobacco. The case 9 is rigid and composed of an assembly of two tubes 2, 3 closed at one of their ends 4, 5. The tubes 2, 3 are nestable one inside the other. For this purpose, a first tube 2 has a diameter slightly smaller than the second tube 3 in order to allow its introduction into the interior of the second 3. Advantageously, the difference in diameter between the first 2 and the second tube 3 is small, less than 1 mm, in order to give the case 9 a good seal.

Le procédé comprend une étape de fabrication de l'étui 9. Pour ce faire, le procédé comprend une étape de découpage d'une longue tige creuse cylindrique, non représenté, afin d'obtenir une pluralité de tubes 2, 3. Par la suite, on procède au thermo scellage d'une extrémité 4, 5 des tubes 2, 3. Pour ce faire, l'extrémité 4, 5 du tube 2, 3 est placée dans une mâchoire chauffante afin d'en souder les bords.The method comprises a step of manufacturing the case 9. To do this, the method comprises a step of cutting a long hollow cylindrical rod, not shown, to obtain a plurality of tubes 2, 3. Thereafter heat sealing is carried out at one end 4, 5 of the tubes 2, 3. To this end, the end 4, 5 of the tube 2, 3 is placed in a heating jaw in order to weld the edges thereof.

Afin de permettre cette opération, les tubes 2, 3 doivent être réalisés dans un matériau thermo soudable. À cet effet, les tubes 2, 3 sont, par exemple, réalisés en polypropylène ou en polyéthylène.In order to allow this operation, the tubes 2, 3 must be made of a heat-sealable material. For this purpose, the tubes 2, 3 are, for example, made of polypropylene or polyethylene.

Les tubes sont découpés à une longueur 12, 13 comprise entre 75 et 95 % de la longueur 11 de la feuille 1 à rouler. Ainsi, la zone de superposition des deux tubes 2, 3 est relativement longue, ce qui permet de conférer à l'étui 9 ainsi réalisé une bonne herméticité. À titre d'exemple, dans un mode de réalisation de l'invention, la longueur I1 d'une feuille 1 à rouler est de 8,5 cm alors que la longueur I2, I3 des tubes 2, 3 est de 7,5 cm.The tubes are cut to a length 12, 13 of between 75 and 95% of the length 11 of the sheet 1 to be rolled. Thus, the superposition area of the two tubes 2, 3 is relatively long, which allows to give the case 9 thus made a good hermeticity. By way of example, in one embodiment of the invention, the length I1 of a sheet 1 to be rolled is 8.5 cm, whereas the length I2, I3 of the tubes 2, 3 is 7.5 cm. .

Le procédé de conditionnement selon l'invention comprend une étape d'insertion de ladite feuille 1 enroulée dans l'étui 9 afin d'obtenir le conditionnement représenté à la figure 3.The packaging method according to the invention comprises a step of inserting said wound sheet 1 into the case 9 in order to obtain the packaging represented in FIG. figure 3 .

Durant cette étape, la feuille 1 enroulée sur elle-même est insérée à l'intérieur d'un des tubes 2, 3, de préférence, le premier tube 2 dont le diamètre est inférieur. Ainsi, la feuille 1 est maintenue enroulée à l'intérieur du tube 2. Par la suite, le premier tube 2 et la feuille 1 sont insérés à l'intérieur du second tube 3 jusqu'à ce que la feuille 1 vienne en butée contre l'extrémité fermée 5 du second tube 3.During this step, the sheet 1 wound on itself is inserted inside one of the tubes 2, 3, preferably the first tube 2 whose diameter is smaller. Thus, the sheet 1 is kept wound inside the tube 2. By the following, the first tube 2 and the sheet 1 are inserted inside the second tube 3 until the sheet 1 comes into abutment against the closed end 5 of the second tube 3.

Afin de solidariser les tubes 2, 3 l'un à l'autre, le procédé comprend en outre une étape d'installation de moyens amovibles 6 de fixation des tubes 2, 3 l'un sur l'autre. Dans le mode de réalisation représenté, les moyens de fixations se composent d'une étiquette adhésive 6 qui est disposée sur l'étui, à cheval sur le premier 2 et le second tube 3. L'étiquette adhésive 6 peut, en outre, comporter des indications sur la feuille 1 à rouler ou des informations publicitaires. Lorsque l'utilisateur souhaite utiliser la feuille 1, il retire préalablement l'étiquette 6 puis ouvre l'étui 9 en faisant coulisser les tubes 2, 3 afin d'accéder à la feuille 1.In order to secure the tubes 2, 3 to one another, the method further comprises a step of installing removable means 6 for fixing the tubes 2, 3 on one another. In the embodiment shown, the fastening means consist of an adhesive label 6 which is arranged on the case, straddling the first 2 and the second tube 3. The adhesive label 6 may also comprise indications on the sheet 1 to roll or advertising information. When the user wishes to use the sheet 1, he removes the label 6 and then opens the case 9 by sliding the tubes 2, 3 to access the sheet 1.

Dans un mode de réalisation préféré, représenté sur la figure 4, des d'étuis 9 sont conditionnés dans un emballe souple permettant d'augmenter l'herméticité du conditionnement afin de garantir la fraîcheur de la feuille 1.In a preferred embodiment, shown in the figure 4 , holsters 9 are packaged in a flexible package to increase the hermeticity of the packaging to ensure the freshness of the sheet 1.

L'emballe souple 7 peut notamment être constitué de deux plaques souples réalisées dans un matériau composite comprenant une feuille d'aluminium recouverte d'une fine pellicule plastique et dont les bords 10 sont soudés l'un à l'autre.The flexible package 7 may in particular consist of two flexible plates made of a composite material comprising an aluminum foil covered with a thin plastic film and whose edges 10 are welded to one another.
