Description

Dosette de boisson  Drink pod
L'invention relève du domaine alimentaire, et en particulier celui des dosettes de boisson et d'additif de boisson. The invention relates to the food field, and in particular that of beverage pods and beverage additive.
Des dosettes peuvent être remplies d'un premier contenu à verser dans un récipient principal contenant lui-même un second contenu pour obtenir un mélange. Par exemple, des dosettes sous forme de sachets étanches contiennent du sirop prévu pour être versé dans une bouteille d'eau. Dans ce cas, la bouteille d'eau doit présenter un volume libre suffisant pour recevoir le contenu de la dosette sous peine de déborder. En outre, l'utilisateur peut verser par maladresse le contenu de la dosette à côté du contenant principal. L'utilisation de telles dosettes est peu pratique. Pods can be filled with a first content to pour into a main container itself containing a second content to obtain a mixture. For example, pods in the form of sealed bags contain syrup intended to be poured into a water bottle. In this case, the water bottle must have a free volume sufficient to receive the contents of the pod under penalty of overflow. In addition, the user can clumsily put the contents of the pod next to the main container. The use of such pods is impractical.
Il existe aussi des dosettes spécifiquement adaptées pour alimenter une machine. C'est par exemple le cas des dosettes contenant du café soluble. Ces dernières ne sont utilisables qu'au moyen d'une machine correspondante. There are also pods specifically adapted to power a machine. This is for example the case of pods containing soluble coffee. These can only be used by means of a corresponding machine.
L'invention vient améliorer la situation. La Demanderesse propose une dosette comprenant un réservoir agencé pour contenir une boisson ou un additif de boisson. Le réservoir est pourvu d'un alésage. La dosette comprend une embouchure s'ouvre sur le réservoir. La dosette comprend au moins une ouverture débouche du réservoir à distance de l'embouchure. La dosette comprend un bouchon de fond présentant une position fermée dans laquelle l'ouverture est obturée de manière étanche aux liquides et une position ouverte dans laquelle l'ouverture est libre. La dosette comprend un piston monté dans ledit alésage. Le piston est mobile entre une première position et une deuxième position. La première position exige que le bouchon de fond soit en position ouverte. Le piston comprend une jupe et un disque solidaires l'un de l'autre. La jupe est pourvue d'une surface extérieure en contact avec le réservoir et d'une surface intérieure munie d'une empreinte agencée pour se connecter de manière étanche sur une ouverture d'un contenant de boisson de sorte qu'au cours de la connexion, le piston passe de la deuxième position à la première position. La dosette comprend une lumière mettant en communication fluidique l'intérieur du réservoir et l'ouverture, la lumière étant ouverte dans la première position et fermée dans la deuxième position du piston. Une telle dosette permet de réaliser un mélange du contenu de la dosette avec celui d'un contenant principal. Les risques de salissure sont réduits. L'opération de mélange peut être réalisée indépendamment du volume libre disponible dans le contenant principal, la dosette formant une extension du volume du contenant principal. Une fois installée sur le contenant principal, l'embouchure de la dosette est utilisée par l'utilisateur pour boire le mélange. L'utilisateur peut refermer l'assemblage du contenant principal et de la dosette en fermant l'embouchure de la dosette. Le mouvement relatif entre la dosette et le contenant principal imprimé par l'utilisateur pour fixer la dosette au contenant principal sert aussi à l'ouverture de la dosette vers le contenant principal. Dans un mode de réalisation, la lumière est radiale et ménagée dans le piston. The invention improves the situation. The Applicant proposes a pod comprising a reservoir arranged to contain a drink or a beverage additive. The tank is provided with a bore. The pod includes a mouth opening to the tank. The pod comprises at least one opening opens the tank remote from the mouth. The pod comprises a bottom cap having a closed position in which the opening is sealed in a liquid-tight manner and an open position in which the opening is free. The pod comprises a piston mounted in said bore. The piston is movable between a first position and a second position. The first position requires the bottom cap to be in the open position. The piston comprises a skirt and a disc integral with one another. The skirt is provided with an outer surface in contact with the reservoir and an inner surface with an imprint arranged to seal on an opening of a beverage container so that during the connection the piston moves from the second position to the first position. The pod comprises a light putting in fluid communication the interior of the tank and the opening, the light being open in the first position and closed in the second position of the piston. Such a pod allows a mixture of the content of the pod with that of a main container. The risks of soiling are reduced. The mixing operation can be performed independently of the free volume available in the main container, the pod forming an extension of the volume of the main container. Once installed on the main container, the mouth of the pod is used by the user to drink the mixture. The user can close the assembly of the main container and the pod by closing the mouth of the pod. The relative movement between the pod and the main container printed by the user to secure the pod to the main container also serves to open the pod to the main container. In one embodiment, the light is radial and formed in the piston.
Dans un mode de réalisation, le réservoir est pourvu d'un alésage de grand diamètre distal et d'un alésage de petit diamètre proximal reliés par un épaulement. Le piston peut être disposé dans l'alésage de petit diamètre. Le disque et l'alésage de petit diamètre peuvent être en liaison étanche en position fermée. Le disque peut être écarté de l'alésage de petit diamètre en position ouverte. La lumière peut être en regard de l'alésage de grand diamètre. In one embodiment, the reservoir is provided with a distal large diameter bore and a small proximal diameter bore connected by a shoulder. The piston can be arranged in the bore of small diameter. The disc and the bore of small diameter may be in tight connection in the closed position. The disc can be discarded from the small diameter bore in the open position. The light can be opposite the bore of large diameter.
Dans un mode de réalisation, le bouchon de fond est fixé à une surface extérieure du réservoir. In one embodiment, the bottom plug is attached to an exterior surface of the tank.
Dans un mode de réalisation, la surface intérieure de la jupe est pourvue d'au moins deux étages filetés, de préférence au moins trois. Les étages filetés sont de diamètre adaptés à un filetage de contenant de boisson. In one embodiment, the inner surface of the skirt is provided with at least two threaded stages, preferably at least three. The threaded stages are of diameter adapted to a thread of beverage container.
Dans un mode de réalisation, l'empreinte de la jupe est un filetage femelle. Dans un mode de réalisation, le piston est en liaison hélicoïdale avec le réservoir. Le filetage femelle et la liaison hélicoïdale peuvent être de même sens de façon que le vissage du contenant de boisson dans le filetage femelle puisse se continuer par le déplacement hélicoïdal du piston de la position fermée vers la position ouverte. In one embodiment, the imprint of the skirt is a female thread. In one embodiment, the piston is helically connected to the reservoir. The female thread and the helical connection can be in the same direction so that the screwing of the beverage container into the female thread can be continued by the helical movement of the piston from the closed position to the open position.
Dans un mode de réalisation, la lumière est en communication avec l'intérieur de la jupe. In one embodiment, the light is in communication with the interior of the skirt.
Dans un mode de réalisation, la lumière comprend une pluralité de portions séparées par les plots formant jonction entre le disque et la jupe. In one embodiment, the light comprises a plurality of portions separated by the pads forming a junction between the disk and the skirt.
Dans un mode de réalisation, le couple de déplacement relatif du piston par rapport au réservoir est compatible avec un usage manuel. Dans un mode de réalisation, le réservoir est cylindro-conique avec une portion cylindrique de petit diamètre voisine de l'embouchure, une portion cylindrique de grand diamètre voisine de l'ouverture et une portion tronconique disposée entre les portions cylindriques de petit diamètre et de grand diamètre. Lesdites portions peuvent être coaxiales. In one embodiment, the relative displacement torque of the piston relative to the reservoir is compatible with manual use. In one embodiment, the reservoir is cylindro-conical with a cylindrical portion of small diameter close to the mouth, a cylindrical portion of large diameter adjacent to the opening and a frustoconical portion disposed between the cylindrical portions of small diameter and of large diameter. Said portions may be coaxial.
Dans un mode de réalisation, le piston est monobloc. In one embodiment, the piston is in one piece.
Dans un mode de réalisation, le piston, dans la deuxième position, affleure l'ouverture. Dans un mode de réalisation, le bouchon de fond est vissé sur le réservoir. In one embodiment, the piston in the second position is flush with the opening. In one embodiment, the bottom cap is screwed onto the reservoir.
Dans un mode de réalisation, la dosette comprend un bouchon de tête. L'embouchure est obturable par le bouchon de tête. Le bouchon de tête peut être vissé sur le réservoir. D'autres caractéristiques, détails et avantages de l'invention apparaîtront à la lecture de la description détaillée ci-après, et des dessins annexés, sur lesquels : - la figure 1 est une vue en coupe longitudinale d'une dosette selon un aspect de l'invention, In one embodiment, the pod comprises a head cap.

Les dessins et la description ci-après contiennent, pour l'essentiel, des éléments de caractère certain. Ils pourront donc non seulement servir à mieux faire comprendre la présente invention, mais aussi contribuer à sa définition, le cas échéant. Des éléments comme la géométrie, les formes et les dimensions de la dosette sont difficiles à définir complètement, autrement que par le dessin. Dans la suite, les termes « haut », « bas », « horizontal », « vertical », « intérieur » et « extérieur » sont utilisés en référence à la disposition et l'orientation d'un assemblage d'une dosette 1 avec un contenant principal 100 posé sur une surface sensiblement horizontale. La dosette 1 présente de manière générale une symétrie axiale d'axe Z, représenté vertical sur les figures. The drawings and the description below contain, for the most part, elements of a certain character. They can therefore not only serve to better understand the present invention, but also contribute to its definition, if any. Elements like geometry, shapes and dimensions of the pod are difficult to define completely, other than by drawing. In the following, the terms "up", "down", "horizontal", "vertical", "inside" and "outside" are used with reference to the arrangement and orientation of an assembly of a pod 1 with a main container 100 placed on a substantially horizontal surface. The pod 1 generally presents an axial symmetry Z axis, shown vertically in the figures.

The outer surface of the lower portion 22 has a groove 28 of rectangular section adjacent to the end of the lower portion 22 opposite the frustoconical portion 23. The groove 28 forms a thinner zone of the wall of the tank 2.
Le piston 3 est réalisé d'un seul tenant. Le piston 3 est fabriqué en matière plastique, par exemple du polytéréphtalate d'éthylène (PET). Le piston 3 peut être formé par injection-soufflage. Le matériau est de qualité alimentaire. Le piston 3 comprend une jupe 31 et un disque 32 solidaires l'un de l'autre. The piston 3 is made in one piece. The piston 3 is made of plastic, for example polyethylene terephthalate (PET). The piston 3 can be formed by injection blow molding. The material is food grade. The piston 3 comprises a skirt 31 and a disc 32 integral with each other.
Le disque 32 présente deux faces planes parallèles et un bord de révolution. L'un des faces planes parallèles est supérieure et, dans la position fermée, forme une surface inférieure de la chambre 24, avec l'épaulement 27. Ladite face plane parallèle supérieure et l'épaulement 27 sont coplanaires. Le disque 32 présente une épaisseur selon l'axe Z nettement inférieure à la hauteur de la jupe 31 aussi selon l'axe Z. Le disque 32 présente une épaisseur selon l'axe Z du même ordre de grandeur que l'épaisseur de la jupe 31 dans un plan normal à l'axe Z, préférablement l'épaisseur de la jupe 31 est comprise entre 50% et 150% de l'épaisseur du disque 32. Le bord de révolution est cylindrique de révolution. Le bord de révolution est de diamètre adapté pour former étanchéité avec la portion de petit diamètre 26. Une interférence légère est souhaitable. Le disque 32 est étanche avec le réservoir 2 dans la position fermée. Le disque 32 présente une structure étanche. The disc 32 has two parallel flat faces and an edge of revolution. One of the parallel plane faces is greater and, in the closed position, forms a lower surface of the chamber 24, with the shoulder 27. Said upper parallel plane face and the shoulder 27 are coplanar. The disc 32 has a thickness along the Z axis substantially lower than the height of the skirt 31 also along the Z axis. The disc 32 has a thickness along the Z axis of the same order of magnitude as the thickness of the skirt 31 in a plane normal to the Z axis, preferably the thickness of the skirt 31 is between 50% and 150% of the thickness of the disk 32. The edge of revolution is cylindrical of revolution. The revolution edge is of a diameter adapted to form a seal with the small diameter portion 26. A slight interference is desirable. The disc 32 is sealed with the reservoir 2 in the closed position. The disc 32 has a sealed structure.
La jupe 31 s'étend à partir du disque 32 selon l'axe Z à l'opposé de la chambre 24. La jupe 31 est en contact avec le réservoir 2. La jupe 31 présente une surface extérieure cylindrique de révolution adaptée pour coulisser, de préférence par un mouvement hélicoïdal, dans la portion de petit diamètre 26 du réservoir 2. La surface extérieure cylindrique peut présenter un diamètre égal ou très légèrement inférieur au diamètre du bord de révolution du disque 32. La jupe 31 présente une surface intérieure étagée de révolution. Chaque étage est cylindrique, lisse, ou de préférence, fileté. Un étage supérieur 33, un étage intermédiaire 34 et un étage inférieur 35 sont ici prévus. L'étage supérieur 33 s'étend jusqu'au disque 32 et présente un premier diamètre. L'étage intermédiaire 34 s'étend jusqu'à l'étage supérieur 33 et présente un deuxième diamètre. L'étage inférieur 35 s'étend jusqu'à l'étage intermédiaire 34 et présente un troisième diamètre. Le troisième diamètre est supérieur au deuxième diamètre. Le deuxième diamètre est supérieur au premier diamètre. Lesdits étages 33, 34, 35 sont reliés deux à deux par des épaulements 36 et 37. Les épaulements 36 et 37 sont radiaux. L'étage intermédiaire 34 et l'étage inférieur 35 sont filetés. Ainsi la surface intérieure de la jupe 31 est munie d'une empreinte agencée pour se connecter de manière étanche sur une ouverture d'un contenant de boisson 100. The skirt 31 extends from the disc 32 along the Z axis opposite the chamber 24. The skirt 31 is in contact with the reservoir 2. The skirt 31 has a cylindrical outer surface of revolution adapted to slide, preferably by a helical movement, in the small diameter portion 26 of the reservoir 2. The cylindrical outer surface may have a diameter equal to or slightly less than the diameter of the edge of revolution of the disc 32. The skirt 31 has a stepped inner surface of revolution. Each stage is cylindrical, smooth, or preferably threaded. An upper stage 33, an intermediate stage 34 and a lower stage 35 are here provided. The upper stage 33 extends to the disc 32 and has a first diameter. The intermediate stage 34 extends to the upper stage 33 and has a second diameter. The lower stage 35 extends to the intermediate stage 34 and has a third diameter. The third diameter is greater than the second diameter. The second diameter is greater than the first diameter. Said stages 33, 34, 35 are connected in pairs by shoulders 36 and 37. The shoulders 36 and 37 are radial. The intermediate stage 34 and the lower stage 35 are threaded. Thus, the inner surface of the skirt 31 is provided with an imprint arranged to connect in a sealed manner to an opening of a beverage container 100.
De préférence, lesdits étages 33, 34, 35 sont filetés. En variante, sont prévus un nombre d'étages filetés supérieur à trois. Des perçages radiaux 38, par exemple au nombre de quatre dans le mode de réalisation représenté, sont ménagés dans la paroi de la jupe 31 au voisinage du disque 32. Les perçages radiaux 38 peuvent affleure le disque 32. Les perçages radiaux 38 sont en nombre d'au moins un et préférablement trois, quatre ou cinq. Les perçages radiaux 38 sont régulièrement répartis sur la circonférence de la jupe 31. Les perçages radiaux 38 sont ici de forme rectangulaire. Les perçages radiaux 38 interfèrent avec l'étage supérieur 33, lui conférant une forme crénelée. Les perçages radiaux 38 laissent subsister des plots 39 entre eux. Les plots 39 relient le disque 32 et la partie annulaire de la jupe 31. Preferably, said stages 33, 34, 35 are threaded. In a variant, a number of threaded stages greater than three is provided. Radial holes 38, for example four in number in the embodiment shown, are formed in the wall of the skirt 31 in the vicinity of the disc 32. The radial bores 38 may be flush with the disc 32. The radial bores 38 are in number of at least one and preferably three, four or five. The radial bores 38 are regularly distributed over the circumference of the skirt 31. The radial bores 38 are here rectangular in shape. The radial bores 38 interfere with the upper stage 33, giving it a crenellated shape. The radial holes 38 leave blocks 39 left between them. The pads 39 connect the disc 32 and the annular portion of the skirt 31.
Dans la position fermée, les perçages radiaux 38 débouchent en cul de sac contre la portion de petit diamètre 26. Dans la position ouverte, les perçages radiaux 38 débouchent dans la chambre 24. Les perçages radiaux 38 sont alors en regard de la portion de grand diamètre 25 avec un passage annulaire contigu entre le bord de révolution du disque 32 et la portion de grand diamètre 25, voir figure 4. In the closed position, the radial bores 38 open out in a dead-end against the small-diameter portion 26. In the open position, the radial bores 38 open into the chamber 24. The radial bores 38 are then opposite the portion of large diameter. 25 with an annular passage contiguous between the edge of revolution of the disc 32 and the large diameter portion 25, see Figure 4.
Le piston 3 est mobile entre la première position et la deuxième position. La première position est ouverte, la communication de liquide entre la chambre 24 et l'ouverture 7 étant autorisée, et la deuxième position est fermée, la communication de liquide entre la chambre 24 et l'ouverture 7 étant interrompue. The piston 3 is movable between the first position and the second position. The first position is open, the liquid communication between the chamber 24 and the opening 7 is allowed, and the second position is closed, the liquid communication between the chamber 24 and the opening 7 being interrupted.
Le bouchon de fond 5 est prévu pour venir se fixer par friction ou vissage sur le réservoir 2. Plus précisément le bouchon de fond 5 est apte à être fixé à la surface extérieure de révolution de la rainure 28. Le bouchon de fond 5 comprend une jupe 51 et un disque d'obturation 52. La jupe 51 est de longueur selon l'axe Z inférieure à la longueur de la rainure 28. La jupe 51 présente une surface intérieure de forme complémentaire à la forme de la surface extérieure de révolution de la rainure 28. Le disque d'obturation 52 est monobloc avec la jupe 51. Le disque d'obturation 52 et la jupe 51 peuvent être de même épaisseur. La première position du piston 3 exige que le bouchon de fond 3 soit préalablement ouvert, en général retiré. The bottom plug 5 is provided to be fixed by friction or screwing on the tank 2. More specifically the bottom plug 5 is adapted to be fixed to the outer surface of revolution of the groove 28. The bottom plug 5 comprises a skirt 51 and a shutter disc 52. The skirt 51 is of length along the Z axis less than the length of the groove 28. The skirt 51 has an inner surface of shape complementary to the shape of the outer surface of revolution of the groove 28. The shutter disc 52 is integral with the skirt 51. The shutter disc 52 and the skirt 51 may be of the same thickness. The first position of the piston 3 requires that the bottom cap 3 is previously opened, generally removed.
Dans l'état illustré sur la figure 2, les pièces de la dosette 1 sont prêtes à l'assemblage. Le piston 3 peut venir par translation axiale dans la portion de petit diamètre 26 pour fermer le bas de la chambre 24. Puis le bouchon de fond 5 peut être fixé au réservoir 2. Dans l'état illustré sur la figure 1, le bouchon de tête 4 et le bouchon de fond 5 sont distants du réservoir 2. Le piston 3 est en position fermée. Le bouchon de fond 5 peut être fixé au réservoir 2. La chambre 24 du réservoir 2 peut être remplie de liquide, par exemple de sirop. Puis le bouchon de tête 4 peut venir obturer le réservoir 2. In the state illustrated in Figure 2, the parts of the pod 1 are ready for assembly. The piston 3 can come by axial translation in the small diameter portion 26 to close the bottom of the chamber 24. Then the bottom cap 5 can be fixed to the reservoir 2. In the state illustrated in Figure 1, the head cap 4 and the bottom cap 5 are distant from the reservoir 2. The piston 3 is in the closed position. The bottom cap 5 can be attached to the tank 2. The chamber 24 of the tank 2 can be filled with liquid, for example syrup. Then the head cap 4 can close the tank 2.
Dans l'état illustré sur la figure 3, la chambre 24 contient du liquide. L'étanchéité entre le piston et le réservoir 2 est opérationnelle. Le bouchon de fond 5 a été ôté. La dosette 1 est prête pour venir coopérer avec le contenant 100. Le contenant 100 comprend un goulot fileté 101 et un réservoir. L'étage intermédiaire 34 et l'étage inférieur 35 ont des diamètres extérieurs dont l'un est adapté au diamètre extérieur du goulot fileté 101. Le goulot fileté 101 peut donc venir se visser dans le piston 3. In the state illustrated in Figure 3, the chamber 24 contains liquid. The seal between the piston and the reservoir 2 is operational. Bottom cap 5 has been removed. The pod 1 is ready to cooperate with the container 100. The container 100 comprises a threaded neck 101 and a reservoir. The intermediate stage 34 and the lower stage 35 have external diameters, one of which is adapted to the outside diameter of the threaded neck 101. The threaded neck 101 can therefore be screwed into the piston 3.
Dans l'état illustré sur la figure 4, le goulot fileté 101 a été vissé dans le piston 3. Le goulot fileté 101 forme une étanchéité avec le piston 3. Le mouvement de vissage du goulot fileté 101 a permis d'entraîner le déplacement du piston 3 vers l'embouchure 6, soit le déplacement du piston 3 de la position fermée à la position ouverte. Les perçages 38 sont débouchants dans la chambre 24. Le liquide s'écoule vers le bas dans le sens de la flèche. Préférablement, la surface extérieure du piston 3 et la portion de petit diamètre 26 sont filetés de manière complémentaire. Le filetage est de même sens que le filetage des étages filetés 34 et 35. De la sorte, le vissage dans l'un des étages filetés 34 et 35 entraîne par un mouvement de même sens, soit une continuation dudit mouvement, l'enfoncement du piston 3 dans le réservoir 2 pour ouvrir la communication entre la chambre 24 et l'intérieur du piston 3. Le filetage peut être de même pas que le filetage des étages filetés 34 et 35 pour rendre le vissage du piston 3 insensible à un utilisateur moyennement attentif. In the state illustrated in Figure 4, the threaded neck 101 has been screwed into the piston 3. The threaded neck 101 forms a seal with the piston 3. The screwing movement of the threaded neck 101 has caused the movement of the piston 3 to the mouth 6, the displacement of the piston 3 from the closed position to the open position. The holes 38 are opening into the chamber 24. The liquid flows downwards in the direction of the arrow. Preferably, the outer surface of the piston 3 and the small diameter portion 26 are threaded in a complementary manner. The threading is in the same sense as the threading of the threaded stages 34 and 35. In this way, the screwing in one of the threaded stages 34 and 35 causes a movement of the same direction, or a continuation of the said movement, the depression of the piston 3 in the tank 2 to open the communication between the chamber 24 and the inside of the piston 3. The threading may be likewise not the threading of the threaded stages 34 and 35 to make the screwing of the piston 3 insensitive to a user moderately attentive.
Ainsi quand le couple de vissage du goulot fileté 101 augmente en fin de vissage dudit goulot fileté 101, ledit couple de vissage exercé par l'utilisateur devient suffisant pour entraîner le piston 3 en rotation hélicoïdale selon le filetage mettant en coopération le piston 3 et le réservoir 2. L'invention ne se limite pas aux exemples de dosettes décrits ci-avant, seulement à titre d'exemple, mais elle englobe toutes les variantes que pourra envisager l'homme de l'art dans le cadre des revendications ci-après. Thus, when the screwing torque of the threaded neck 101 increases at the end of screwing of said threaded neck 101, said screwing torque exerted by the user becomes sufficient to drive the piston 3 in helical rotation along the threading which puts the piston 3 and the piston in contact with each other. tank 2. The invention is not limited to the examples of pods described above, only by way of example, but it encompasses all the variants that may be considered by those skilled in the art within the scope of the claims below.
