Description

La présente invention concerne un récipient muni d'un dispositif permettant l'absorption d'une boisson de façon hygiénique évitant que le consommateur ne pose les lèvres sur une partie externe dudit récipient et plus particulièrement le dispositif d'extraction d'une paille du récipient.The present invention relates to a container provided with a device allowing the absorption of a drink in a hygienic way avoiding that the consumer does not put the lips on an external part of said container and more particularly the device for extracting a straw from the container.

Il existe sur le marché de nombreux types de récipients : bouteilles plastiques, bouteilles en verre, canettes métalliques, emballages cartonnés pouvant avoir des formes diverses permettant le conditionnement de tout type de produits liquides alimentaires.There are many types of containers on the market: plastic bottles, glass bottles, metal cans, packaging cardboard can have various shapes allowing the packaging of all types of liquid food products.

Ces différents récipients présentent l'inconvénient pour l'utilisateur d'être soit peu hygiéniques lorsque l'on veut boire à même le récipient, soit peu pratiques selon la forme et la dimension du goulot, voire la forme même du récipient.These different containers have the drawback for the user to be unhygienic when drinking from the container, either impractical depending on the shape and size of the neck, or even the shape of the container.

Dans le cas particulier des canettes métalliques ou des emballages cartonnés utilisés pour des boissons diverses et variées du type bières, boissons gazeuses, jus de fruit ou lait, ceux-ci sont très peu hygiéniques. En effet, depuis leurs lieux de production au moment où la boisson a été conditionnée, ceux-ci sont transportés et déchargés sans aucune mesure d'hygiène spécifique puis vendus au consommateur par un détaillant qui les stocke sans précaution d'hygiène particulière et les manipule manuellement. Au cours de ces différentes manipulations, il peut se déposer sur les parois des récipients divers microbes, virus, bactéries ou poussières que le consommateur absorbera lorsqu'il apposera ses lèvres au récipient.In the particular case of metal cans or packaging cardboard boxes used for various and varied beers of the beer type, soft drinks, fruit juice or milk, these are very unhygienic. In indeed, from their places of production at the time the drink was conditioned, these are transported and unloaded without any measures specific hygiene products then sold to the consumer by a retailer who stores them without special hygiene precautions and handles them manually. During these various manipulations, it may deposit various microbes, viruses, bacteria or dust that consumers will absorb when they put their lips to the container.

Par ailleurs, dans le cas particulier de canettes métalliques et indépendamment des problèmes d'hygiène, le consommateur peut être gêné lors de l'absorption de la boisson par des problèmes d'écoulement intempestif provoquant le plus souvent des tâches sur ses habits.Furthermore, in the particular case of metal cans and regardless of hygiene issues, the consumer can be embarrassed during absorption of the drink by flow problems nuisance most often causing stains on his clothes.

Le document WO-A-89/01750 divulgue un dipositif d'extraction automatique d'une paille disposée à l'intérieur d'un récipient, ledit dispositif étant énergisé et mis en mouvement, sous l'action externe des moyens d'ouverture de la canette. Document WO-A-89/01750 discloses a device for automatic extraction of a straw placed inside a container, said device being energized and set in motion, under the external action of the opening means of the can.

Afin d'éviter lesdits inconvénients, l'invention se propose par des moyens simples et peu coûteux de résoudre ces problèmes pratiques et hygiéniques grâce à un dispositif d'extraction automatique d'une paille située à l'intérieur du récipient.In order to avoid said drawbacks, the invention proposes by simple and inexpensive ways to solve these practical problems and hygienic thanks to an automatic straw extraction device located inside the container.

Ainsi, selon sa caractéristique principale, le dispositif d'extraction automatique d'une paille disposée à l'intérieur d'un récipient muni de moyens d'ouverture du type canette cylindrique par exemple, est caractérisé en ce qu'il comporte :

  • un organe support de paille mobile entre une position libre où la paille qu'il supporte présente son extrémité dans l'orifice des moyens d'ouverture du récipient et une position verrouillée où ladite extrémité est disposée à l'intérieur du récipient,
  • des moyens de sollicitation de l'organe support de paille destinés à solliciter celui-ci de sa position verrouillée vers sa position libre,
  • des moyens de verrouillage destinés à bloquer l'organe support de paille dans sa position verrouillée,
  • des moyens de déverrouillage destinés à libérer l'organe support de sa position verrouillée.
Thus, according to its main characteristic, the device for automatically extracting a straw placed inside a container provided with opening means of the cylindrical can type, for example, is characterized in that it comprises:
  • a straw support member movable between a free position where the straw which it supports has its end in the orifice of the means for opening the container and a locked position where said end is disposed inside the container,
  • means for urging the straw support member intended to urge the latter from its locked position to its free position,
  • locking means intended to block the straw support member in its locked position,
  • unlocking means intended to release the support member from its locked position.

Selon une autre caractéristique, l'organe support de paille est constitué par un bras support muni de moyens de retenue de la paille à son extrémité, ledit bras étant articulé entre sa position libre et sa position verrouillée sur une pièce intermédiaire indépendante solidaire du récipient.According to another characteristic, the straw support member is constituted by a support arm provided with means for retaining the straw to its end, said arm being articulated between its free position and its locked position on a separate independent intermediate piece of the container.

Selon le mode de réalisation préféré du dispositif d'extraction automatique d'une paille selon l'invention, les moyens de sollicitation de la paille sont constitués par l'articulation du bras support de paille sur la pièce intermédiaire indépendante et/ou par le bras lui même et sont obtenus grâce à la flexibilité et à l'élasticité du matériau utilisé pour réaliser le bras, la pièce et l'articulation qui les relie.According to the preferred embodiment of the extraction device automatic straw according to the invention, the biasing means of the straw are formed by the articulation of the straw support arm on the independent intermediate piece and / or by the arm itself and are obtained thanks to the flexibility and elasticity of the material used for realize the arm, the part and the articulation which connects them.

Selon un mode de réalisation du dispositif d'extraction automatique d'une paille, les moyens de verrouillage sont constitués par un bras secondaire de verrouillage qui présente à son extrémité un ensemble de surfaces de butée destinées à coopérer avec des surfaces d'appui complémentaires portées par l'organe support de paille lorsque celui-ci est en position verrouillée.According to one embodiment of the extraction device automatic of a straw, the locking means are constituted by a secondary locking arm which has at its end a set of abutment surfaces intended to cooperate with surfaces additional support carried by the straw support member when it is in the locked position.

Selon ce mode de réalisation, les moyens de déverrouillage sont constitués par une patte de déverrouillage portée par le bras secondaire de verrouillage et destinée à coopérer avec les moyens d'ouverture du récipient pour provoquer le déplacement du bras secondaire vers une position extrême de libération où ses surfaces de butée ne coopèrent plus avec les surfaces d'appui complémentaires de l'organe support de paille.According to this embodiment, the unlocking means are constituted by an unlocking tab carried by the secondary arm locking and intended to cooperate with the opening means of the container to cause the displacement of the secondary arm towards a extreme release position where its abutment surfaces no longer cooperate with the complementary bearing surfaces of the straw support member.

    L'invention concerne un dispositif d'extraction automatique portant la référence générale (1) destiné à extraire automatiquement lors de son ouverture une paille (2) disposée à l'intérieur d'un récipient (3). Le dispositif d'extraction (1) est avantageusement décrit dans le cas particulier des canettes cylindriques métalliques dont les moyens d'ouverture (MO) sont constitués de manière connue en soi par un anneau poussoir (6) et une languette prédécoupée (7) qui peut pivoter vers l'intérieur du récipient (3) sous l'action de l'anneau pour libérer l'orifice (5) desdits moyens d'ouverture, comme le montrent les figures 1 et 2. Il va de soi que le dispositif d'extraction automatique selon l'invention pourrait être modifié pour être adapté à d'autres types de récipients ou à d'autres types de moyens d'ouverture sans pour autant sortir du champ de protection de l'invention.The invention relates to an automatic extraction device bearing the general reference (1) intended to extract automatically when from its opening a straw (2) disposed inside a container (3). The extraction device (1) is advantageously described in the case particularly metallic cylindrical cans whose means opening (MO) are constituted in a manner known per se by a push ring (6) and a pre-cut tongue (7) which can pivot towards the inside of the container (3) under the action of the ring to release the orifice (5) of said opening means, as shown in Figures 1 and 2. It goes without saying that the automatic extraction device according to the invention could be modified to be adapted to other types of receptacles or other types of opening means without go beyond the protective field of the invention.

    Selon l'invention, le dispositif d'extraction automatique (1) de la paille (2) comporte un organe support de paille (4) mobile entre une position verrouillée (B) où la paille (2) se trouve à l'intérieur du récipient (3) et qui correspond à la position fermée des moyens d'ouverture (MO) et une position libre (A) où l'organe support (4) présente l'extrémité (2a) de la paille (2) au niveau de l'orifice (5) et qui correspond à la position ouverte desdits moyens d'ouverture. Le dispositif comporte également des moyens de sollicitation (MS) de l'organe support de paille (4) qui tendent à le faire se déplacer de sa position verrouillée (B) vers sa position libre (A). Par ailleurs, il est prévu des moyens de verrouillage (MV) destinés à bloquer l'organe support de paille (4) dans sa position verrouillée (B) et des moyens de déverrouillage (MDV) destinés à provoquer la libération dudit organe. De plus, les moyens de déverrouillage (MDV) sont avantageusement réalisés de manière à être actionnés par les moyens d'ouverture (MO) du récipient (3) lorsque le consommateur effectue l'ouverture de l'orifice (5).According to the invention, the automatic extraction device (1) of the straw (2) comprises a straw support member (4) movable between a locked position (B) where the straw (2) is inside the container (3) and which corresponds to the closed position of the opening means (MO) and a free position (A) where the support member (4) has the end (2a) straw (2) at the orifice (5) and which corresponds to the position open said opening means. The device also includes biasing means (MS) of the straw support member (4) which tend to make it move from its locked position (B) to its free position (A). Furthermore, locking means are provided. (MV) intended to block the straw support member (4) in its position locked (B) and unlocking means (MDV) intended for cause the release of said organ. In addition, the means of unlocking (MDV) are advantageously made so as to be actuated by the opening means (MO) of the container (3) when the consumer opens the orifice (5).

    Selon le mode de réalisation préféré du dispositif d'extraction selon l'invention, l'organe support de paille est constitué par un bras (4) portant à son extrémité (4a) des moyens de retenue de la paille (2) telle qu'une portion de tube (10) à l'intérieur de laquelle est disposée l'extrémité (2a) de ladite paille. Le bras support de paille (4) est avantageusement articulé sur une pièce intermédiaire indépendante (9) disposée à l'intérieur du récipient et solidaire de celui-ci grâce à des moyens de fixation qui seront décrits ultérieurement.According to the preferred embodiment of the extraction device according to the invention, the straw support member is constituted by an arm (4) carrying at its end (4a) means for retaining the straw (2) such a portion of tube (10) inside which is disposed the end (2a) of said straw. The straw support arm (4) is advantageously articulated on an independent intermediate piece (9) arranged inside the container and secured to it by means of fixing means which will be described later.

    Selon ce mode de réalisation préféré, les moyens de verrouillage (MV) illustrés figure 4 sont avantageusement constitués par un organe de verrouillage comme, par exemple, un bras secondaire de verrouillage (8) qui présente à son extrémité (8a) un ensemble de surfaces de butée (11), à savoir, deux butées latérales (11a, 11b) et une butée inférieure (11c). Les surfaces de butée latérales (11a, 11b) et inférieure (11c) sont destinées à coopérer avec des surfaces d'appui (12, 12a, 12b, 12c) complémentaires portées par le bras support de paille (4) lorsque le dispositif d'extraction (1) est en position verrouillée (B). Le bras secondaire (8) est avantageusement articulé à son autre extrémité sur la pièce intermédiaire indépendante (9), cependant il va de soi qu'il pourrait fort bien être articulé sur une autre pièce solidaire de la canette (3).According to this preferred embodiment, the locking means (MV) illustrated in Figure 4 are advantageously constituted by a locking such as, for example, a secondary locking arm (8) which has at its end (8a) a set of abutment surfaces (11), namely, two lateral stops (11a, 11b) and a lower stop (11c). The lateral (11a, 11b) and lower (11c) abutment surfaces are intended to cooperate with complementary bearing surfaces (12, 12a, 12b, 12c) carried by the straw support arm (4) when the extraction device (1) is in the locked position (B). The secondary arm (8) is advantageously articulated at its other end on the intermediate piece independent (9), however it goes without saying that it could very well be articulated on another piece integral with the bobbin (3).

    Selon le mode de réalisation préféré du dispositif d'extraction automatique de la paille (1), la pièce intermédiaire (9) est réalisée dans un matériau légèrement flexible et possédant une certaine élasticité. Le bras support (4) et le bras secondaire (8) étant constitués par des prolongements de la pièce intermédiaire (9), leur articulation avec celle-ci s'effectue selon une charnière (13, 14) formée de manière connue en soi, par exemple, par un rétrécissement de la section des prolongements formant les bras. L'élasticité du matériau utilisé permet aux bras articulés (4, 8) d'être sollicités élastiquement vers leurs positions initiales respectives qui correspondent chacune à la position libre du dispositif d'extraction (1) comme le montrent les figures 5b et 6b. L'élasticité du bras support de paille (4) tend en permanence à le rappeler vers sa position libre (A) et constitue ainsi les moyens de sollicitation (MS) du dispositif d'extraction (1). Cependant, lesdits moyens pourraient être obtenus par tout dispositif de rappel élastique équivalent, comme par exemple situés sur les charnières ou articulations des bras sans pour autant sortir du champ de protection revendiqué de l'invention.According to the preferred embodiment of the extraction device automatic straw (1), the intermediate piece (9) is made in a slightly flexible material with a certain elasticity. The support arm (4) and the secondary arm (8) being constituted by extensions of the intermediate piece (9), their articulation with this is carried out according to a hinge (13, 14) formed in a known manner per se, for example, by a narrowing of the section of extensions forming the arms. The elasticity of the material used allows the articulated arms (4, 8) to be urged elastically towards their positions respective initials which each correspond to the free position of the extraction device (1) as shown in Figures 5b and 6b. The elasticity of the straw support arm (4) permanently tends to recall towards its free position (A) and thus constitutes the means of stress (MS) of the extraction device (1). However, said means could be obtained by any elastic return device equivalent, such as located on the hinges or joints arms without departing from the claimed protective field of the invention.

    Selon le mode de réalisation préféré du dispositif d'extraction (1), la sollicitation des bras articulés (4, 8) due à l'élasticité de leurs matériaux lorsqu'ils sont fléchis en position verrouillée (B) permet de faire coopérer les surfaces de butée et d'appui respectives (11, 12) à l'encontre des forces de rappel qui s'exercent sur lesdits bras selon un principe d'arcs boutants connu en soi illustré schématiquement figure 3a. Ainsi, l'ensemble desdites surfaces d'appui et de butée permet de positionner et de maintenir les bras articulés et essentiellement le bras support de paille (4) dans une position verrouillée (B) comme le montrent les figures 5a et 6a, où l'extrémité (2a) de la paille (2) qu'il porte se trouve en retrait à l'intérieur de la canette (3) et où le bras support de paille (4) est sollicité vers sa position libre (A) grâce à son élasticité et à sa position fléchie.According to the preferred embodiment of the extraction device (1), the stress on the articulated arms (4, 8) due to the elasticity of their materials when bent in the locked position (B) allows cause the respective abutment and bearing surfaces (11, 12) to cooperate with against the restoring forces exerted on said arms according to a principle of flying arcs known per se illustrated schematically in Figure 3a. Thus, all of said bearing and abutment surfaces allow position and maintain the articulated arms and essentially the arm straw holder (4) in a locked position (B) like the show Figures 5a and 6a, where the end (2a) of the straw (2) it door is set back inside the bobbin (3) and where the arm straw support (4) is biased towards its free position (A) thanks to its elasticity and in its bent position.

    Notons que, selon le mode de réalisation préféré du dispositif, l'articulation (13) du bras support (4) est réalisée de manière à ce qu'il passe de sa position verrouillée (B) où l'extrémité (2a) de la paille (2) est située dans un plan horizontal (H1) situé en dessous du plan horizontal (H) comportant l'orifice (5) et décalé par rapport à cet orifice, comme le montrent les figures 3a et 7a, vers une position libre (A) où l'extrémité (2a) est disposée dans un plan (H2) situé légèrement au-dessus du plan (H) de l'orifice, à l'aplomb de celui-ci, tel qu'illustré figures 3d, 7b, 8b et 10. Le déplacement du bras support (4) s'effectue ainsi en pivotement dans un plan incliné orthogonal à l'axe de son articulation (14) de manière à permettre le passage de l'extrémité (2a) de la paille (2) dans l'orifice (5).Note that, according to the preferred embodiment of the device, the articulation (13) of the support arm (4) is made so that it goes from its locked position (B) where the end (2a) of the straw (2) is located in a horizontal plane (H1) located below the horizontal plane (H) comprising the orifice (5) and offset with respect to this orifice, like the show figures 3a and 7a, towards a free position (A) where the end (2a) is arranged in a plane (H2) located slightly above the plane (H) of the orifice, directly above it, as illustrated in Figures 3d, 7b, 8b and 10. The movement of the support arm (4) is thus carried out in pivoting in an inclined plane orthogonal to the axis of its articulation (14) of so as to allow the passage of the end (2a) of the straw (2) in the orifice (5).

    Le dispositif d'extraction (1) comporte également des moyens de déverrouillage (MDV) qui permettent lors de l'actionnement des moyens d'ouverture (MO) du récipient (3) illustrée schématiquement figure 3b de libérer le bras support (4) de sa position verrouillée (B). Selon le mode de réalisation préféré, les moyens de déverrouillage sont constitués par une patte de déverrouillage (15) disposée sur le bras secondaire de verrouillage (8) et destinée à être actionnée lors de l'ouverture du récipient par le pivotement vers l'intérieur de la canette (3) de la languette prédécoupée (7) ou opercule des moyens d'ouverture de façon à provoquer le déplacement par pivotement autour de son articulation (14) du bras secondaire vers une position extrême de libération (D) illustrée schématiquement figure 3b. Le pivotement du bras secondaire vers sa position de libération (D) permet de libérer l'ensemble des surfaces de butée et d'appui complémentaires (11a, 11b, 11c, 12a, 12b, 12c) qui coopéraient entre elles dans la position verrouillée (B) de manière à ce que le bras support de paille (4) soit rappelé vers sa position libre (A) grâce aux moyens de sollicitation (MS), comme le montre la figure 3c, la patte de déverrouillage cessant ensuite de coopérer avec la languette prédécoupée de manière à libérer également le bras secondaire.The extraction device (1) also comprises means for unlocking (MDV) which allow upon actuation of the means opening (MO) of the container (3) illustrated schematically in Figure 3b of release the support arm (4) from its locked position (B). Depending on the mode preferred embodiment, the unlocking means are constituted by an unlocking tab (15) arranged on the secondary arm of locking (8) and intended to be actuated when the container by pivoting inward of the can (3) of the precut tab (7) or covers opening means so to cause displacement by pivoting around its articulation (14) from the secondary arm to an extreme release position (D) schematically illustrated in Figure 3b. The pivoting of the secondary arm towards its release position (D) frees all of the complementary abutment and support surfaces (11a, 11b, 11c, 12a, 12b, 12c) which cooperated with each other in the locked position (B) of so that the straw support arm (4) is pulled towards its free position (A) thanks to the biasing means (MS), such as shows figure 3c, the release tab then ceasing to cooperate with the tongue precut so as to also release the arm secondary.

    Par ailleurs, selon le mode de réalisation préféré, le bras secondaire de déverrouillage (8) est également sollicité vers sa position libre (A) par des moyens de sollicitation complémentaires obtenus également par l'élasticité du matériau utilisé pour le réaliser ou par des moyens de rappel élastiques situés sur l'articulation (14) du bras sur la pièce intermédiaire (9). Lors du déverrouillage, le bras secondaire (8) passe au-dessus du bras support (4) pour libérer les surfaces d'appui et de butée des deux bras articulés qui coopèrent. Ensuite, les deux bras subissent chacun une force de rappel de leurs moyens de sollicitation respectifs et viennent se positionner en position libre. Notons que le bras secondaire de déverrouillage (8) chevauche le bras support (4) pour passer dessous et permettre ainsi par sa force de rappel propre de solliciter également vers le haut (HA) le bras support (4) de manière à l'amener vers sa position libre (A).Furthermore, according to the preferred embodiment, the arm secondary release (8) is also biased towards its position free (A) by additional means of solicitation obtained also by the elasticity of the material used to make it or by elastic return means located on the articulation (14) of the arm on the intermediate piece (9). When unlocking, the secondary arm (8) passes over the support arm (4) to free the support surfaces and stop of the two articulated arms which cooperate. Then the two arms each undergo a force of recall of their means of solicitation respective and are positioned in the free position. Note that the arm secondary release (8) overlaps the support arm (4) to pass underneath and thereby allow by its own return force to also push the support arm (4) upwards (HA) so as to bring it to its free position (A).

    Notons que les bras articulés (4, 8), les moyens de retenue de la paille (2), le bras support (4), les surfaces d'appui et de butée, le bras secondaire (8) et la pièce intermédiaire (9) sont avantageusement réalisés d'un seul tenant et forment une seule et même pièce qui se présente sous la forme d'une bague annulaire (9) destinée à être disposée à l'intérieur (INT) de la canette (3) sous la paroi supérieure (16) sur laquelle sont disposés les moyens d'ouverture de ladite canette comme le montre la figure 8a.Note that the articulated arms (4, 8), the means for retaining the straw (2), the support arm (4), the bearing and abutment surfaces, the arm secondary (8) and the intermediate part (9) are advantageously made in one piece and form a single piece which is presented under the shape of an annular ring (9) intended to be arranged inside (INT) of the bobbin (3) under the upper wall (16) on which are arranged the means for opening said can as shown in the Figure 8a.

    Selon le mode de réalisation préféré de l'invention, la bague annulaire (9) est réalisée dans une matière plastique du type de celles utilisées dans l'industrie alimentaire pour pouvoir être disposée au contact du liquide destiné à être consommé. Elle peut avantageusement être réalisée par un procédé d'injection ou par tout autre procédé équivalent.According to the preferred embodiment of the invention, the ring annular (9) is made of a plastic material of the type used in the food industry to be able to be contact of the liquid intended to be consumed. It can advantageously be made by an injection process or by any other process equivalent.

    Notons également que la paille (2) peut être constituée par deux portions de paille (20a, 20b) coaxiales dont une (20a) est retenue par les moyens de retenue (10) du bras support de paille (4) et dont l'autre (20b) coulisse à l'intérieur de la première (20a) comme le montre la figure 10 et permet ainsi à l'utilisateur d'en extraire une partie pour boire tout en maintenant l'extrémité inférieure (2b) de la portion de paille (20a) au niveau du fond (17) du récipient (3) pour permettre d'en aspirer l'intégralité du contenu. La portion de paille supérieure (20b) peut avantageusement comporter un bourrelet annulaire de retenue (18) destiné à empêcher celle-ci de coulisser intégralement dans la portion inférieure (20a). Le bourrelet (18) est situé sur la portion de paille (20b) de manière à ce que son extrémité supérieure (2a) soit située légèrement au-dessus du plan (H) de l'orifice (5) lorsque le dispositif d'extraction (1) est en position libre (A).Note also that the straw (2) can consist of two coaxial portions of straw (20a, 20b), one of which (20a) is retained by the retaining means (10) of the straw support arm (4) and of which the other (20b) slides inside the first (20a) as shown in Figure 10 and thus allows the user to extract part of it for drinking while maintaining the lower end (2b) of the straw portion (20a) at the level of the bottom (17) of the container (3) to allow suction the entire content. The upper straw portion (20b) can advantageously include an annular retaining bead (18) designed to prevent it from sliding fully into the portion lower (20a). The bead (18) is located on the portion of straw (20b) so that its upper end (2a) is located slightly above the plane (H) of the orifice (5) when the extraction device (1) is in the free position (A).

    Il est important de noter que la bague annulaire (9) peut avantageusement comporter des moyens d'étanchéité constitués par son rebord périphérique (19). Ainsi, lors du conditionnement de la canette (3) avec son dispositif d'extraction (1) illustrée figure 9a et 9b, le rebord périphérique (19) peut avantageusement remplacer les joints silicones utilisés par les fabricants pour assurer l'étanchéité entre la paroi périphérique (21) de la canette et sa paroi supérieure (16), ledit rebord étant pincé entre les deux parois lorsque celles-ci sont assemblées ensemble par sertissage par exemple tel que le montre en détail la figure 9c. Ainsi selon les différents modes de réalisation, le dispositif d'extraction est constitué par une pièce indépendante (9) qui peut être disposée et fixée dans le récipient et en particulier dans une canette sans nécessiter de modification structurelle de celle-ci.It is important to note that the annular ring (9) can advantageously include sealing means constituted by its peripheral edge (19). So when packaging the can (3) with its extraction device (1) illustrated in FIGS. 9a and 9b, the rim device (19) can advantageously replace silicone seals used by manufacturers to seal between the wall device (21) of the bobbin and its upper wall (16), said rim being pinched between the two walls when these are assembled assembly by crimping for example as shown in detail in the figure 9c. Thus according to the different embodiments, the device extraction consists of an independent part (9) which can be arranged and fixed in the container and in particular in a can without require structural modification of it.

    Par ailleurs, selon les différents modes d'exécution du dispositif d'extraction, la bague annulaire (9) le constituant peut avantageusement être réalisée par un procédé d'injection du type bimatière, de manière à obtenir une pièce réalisée dans une première matière plastique relativement rigide munie d'un rebord périphérique (19) réalisé dans une deuxième matière plastique plus souple injectée simultanément de manière connue en soi. Ainsi, lors de la mise en place du dispositif dans la canette, le rebord périphérique relativement flexible permet de réaliser une étanchéité parfaite entre la paroi supérieure (16) et la paroi périphérique (21) de la canette (3) comme le montre la figure 9c, alors que la rigidité relative de la pièce centrale principale permet le fonctionnement optimal du dispositif et notamment la sollicitation élastique des bras de leur position verrouillée (B) où ils se trouvent en position légèrement fléchi vers leur position libre (A).Furthermore, according to the different modes of execution of the device extraction, the annular ring (9) constituting it can advantageously be carried out by an injection process of the bi-material type, so as to obtain a part made from a first plastic material relatively rigid provided with a peripheral rim (19) produced in a second softer plastic material injected simultaneously with in a manner known per se. Thus, during the installation of the device in the bobbin, the relatively flexible peripheral rim makes it possible a perfect seal between the upper wall (16) and the wall device (21) of the bobbin (3) as shown in FIG. 9c, then that the relative rigidity of the main central part allows the optimal functioning of the device and in particular the stress elastic of the arms from their locked position (B) where they are in position slightly bent towards their free position (A).

    Selon un deuxième mode de réalisation illustré schématiquement figure 11, le dispositif d'extraction (1) comporte un bras support de paille (4) articulé et sollicité vers sa position libre (A) du type de celui décrit dans le mode de réalisation précédent. Toutefois, les moyens de verrouillage (MV) ne sont plus constitués par un bras secondaire, mais par un système de butée (22) en forme de cran solidaire de la pièce intermédiaire (9) sur laquelle le bras support (4) peut être disposé en position verrouillée (B), ledit bras étant sollicité par ses moyens de sollicitation (MS) vers sa position libre (A).According to a second embodiment illustrated schematically Figure 11, the extraction device (1) comprises a straw support arm (4) articulated and biased towards its free position (A) of the type described in the previous embodiment. However, the means to locking (MV) are no longer constituted by a secondary arm, but by a stop system (22) in the form of a notch secured to the part intermediate (9) on which the support arm (4) can be arranged in locked position (B), said arm being biased by its means of bias (MS) to its free position (A).

    Selon ce mode de réalisation, les moyens de déverrouillage (MDV) sont constitués par une patte de déverrouillage (23) formée par une portion de paroi en saillie du bras support de paille (4). Cette patte (23) est destinée à coopérer avec la languette prédécoupée (7) des moyens d'ouverture (MO) de la canette lorsque celle-ci pivote vers l'intérieur pour libérer le bras support (4) de sa butée (22) à l'encontre de la sollicitation des moyens de sollicitation (MS). Lorsque ledit bras (4) est sorti de son cran et que la patte de déverrouillage cesse de coopérer avec la languette prédécoupée (7), les moyens de sollicitation rappellent le bras vers sa position libre,According to this embodiment, the unlocking means (MDV) consist of an unlocking tab (23) formed by a portion of the wall projecting from the straw support arm (4). This paw (23) is intended to cooperate with the precut tab (7) of the opening means (MO) of the bobbin when the latter pivots towards inside to release the support arm (4) from its stop (22) against solicitation of the means of solicitation (MS). When said arm (4) is out of its notch and the release tab stops cooperating with the precut tab (7), the biasing means remind the arm towards its free position,

    Notons que, selon ce mode de réalisation, le déverrouillage du bras (4) qui s'effectue grâce à la patte de déverrouillage (23) permet de confier au bras une énergie potentielle supérieure à celle qu'elle possède en position verrouillée puisque le bras (4) est déplacé à rencontre de la force de rappel des moyens de sollicitation (MS) d'une hauteur nécessaire pour passer le cran, la butée (22) permet ainsi de donner une énergisation complémentaire au bras (4) afin de faciliter son positionnement en position libre (A) lorsqu'il se libère de ladite butée. Notons que le rebord latéral (22a) de la butée (22) peut avantageusement être incliné et légèrement incurvé, et peut de ce fait constituer des moyens de guidage du bras support (4), permettant de le guider depuis sa position extrême de libération où il sort du cran vers sa position libre.Note that, according to this embodiment, the unlocking of the arm (4) which is effected by the release tab (23) allows give the arm more potential energy than it has in the locked position since the arm (4) is moved against the return force of the biasing means (MS) from a height necessary to pass the notch, the stop (22) thus makes it possible to give a complementary energy to the arm (4) to facilitate its positioning in free position (A) when it is released from said stop. Note that the lateral flange (22a) of the stop (22) can advantageously be inclined and slightly curved, and may therefore constitute means for guiding the support arm (4), allowing it to be guided from its extreme position of release where it leaves the notch towards its free position.

    Il est également important de noter que, selon ce mode de réalisation, lorsqu'il est position libre, le bras support (4) est disposé dans le même plan que la butée (22) et est disposé à côté de celle-ci. De cette façon, lors du procédé d'injection destiné à produire en grande série la bague circulaire (9) du dispositif d'extraction (1), le moule utilisé est un moule simple, et moins onéreux que dans d'autres modes de réalisation légèrement plus complexes et qui peuvent nécessiter l'utilisation de moules dits à tiroir.It is also important to note that, according to this mode of embodiment, when in the free position, the support arm (4) is arranged in the same plane as the stop (22) and is arranged next to it. Of this way during the injection process intended to produce large series the circular ring (9) of the extraction device (1), the mold used is a simple mold, and less expensive than in other modes of slightly more complex and which may require the use of so-called drawer molds.

    Selon un troisième mode de réalisation où les moyens de verrouillage (MV) sont, par exemple, constitués par une butée (22), le dispositif d'extraction (1) peut présenter des moyens d'immobilisation complémentaires destinés à permettre l'immobilisation de la paille (2) à l'intérieur de la canette (3) lorsque le bras support (4) est en position verrouillée (B). De ce fait, lors du transport et du stockage des canettes (3) de boisson, ces moyens d'immobilisation réduisent les sollicitations sur le bras support (4) et permettent ainsi d'éviter la libération intempestive de celui-ci. Ainsi, comme les montrent les figures 12, 13 et 14 où les organes constitutifs du dispositif d'extraction (1) portent des références similaires à celles utilisées dans les modes de réalisations précédemment décrits pour des organes équivalents, les moyens d'immobilisation complémentaires de la paille (2) sont constitués par une portion de tube (30) ouverte vers le bas (BA) et située sur la pièce intermédiaire (9) dans l'axe de la paille (2) lorsque celle-ci est en position verrouillée (B). De ce fait, dans cette position verrouillée (B), l'extrémité (2a) de la paille (2) vient se loger dans la portion de tube (30) pour y être immobilisée. Notons que la hauteur (h1) de l'extrémité de la paille (2a) qui est engagée dans la portion de tube (30) est inférieure à la hauteur (h2) de butée que la paille (2) et le bras support (4) doivent parcourir pour parvenir à la position de libération, comme le montre la figure 14. Ainsi, lors de l'actionnement des moyens d'ouverture (MO), l'extrémité de la paille (2a) sort de la portion de tube (30) avant que le bras n'atteigne sa position de libération.According to a third embodiment where the means of locking (MV) are, for example, constituted by a stop (22), the extraction device (1) can have immobilization means intended to allow the immobilization of the straw (2) to inside the bobbin (3) when the support arm (4) is in position locked (B). Therefore, during transport and storage of cans (3) drink, these immobilization means reduce the stresses on the support arm (4) and thus make it possible to avoid release untimely of it. Thus, as shown in Figures 12, 13 and 14 where the constituent parts of the extraction device (1) carry references similar to those used in the embodiments previously described for equivalent bodies, the means additional immobilization of straw (2) consist of a portion of tube (30) open downward (BA) and located on the part intermediate (9) in the axis of the straw (2) when it is in locked position (B). Therefore, in this locked position (B), the end (2a) of the straw (2) is housed in the tube portion (30) to be immobilized there. Note that the height (h1) of the end of the straw (2a) which is engaged in the portion of tube (30) is less than the stop height (h2) that the straw (2) and the support arm (4) must travel to reach the release position, as shown in the FIG. 14. Thus, when the opening means (MO) are actuated, the end of the straw (2a) comes out of the tube portion (30) before the arm does not reach its release position.

    Selon ce troisième mode de réalisation, le bras support (4) ou plus précisément son articulation sur la pièce intermédiaire (9) présente des moyens de répartition de contrainte destinés à éviter d'avoir une zone où les contraintes et les déformations sont trop importantes et qui pourraient amener à la rupture ou à l'endommagement de l'articulation. Ainsi, comme le montrent les figures 12 et 13, le bras support (4) possède à proximité de son embase, des profils de section qui présentent des plats latéraux parallèles. Cette configuration permet de rigidifier le bras (4) lorsqu'il travaille en flexion et de répartir les contraintes dans l'ensemble de l'articulation qui comprend deux portions de bras (31a, 31b) qui présentent chacune des plats latéraux déformables élastiquement disposés orthogonalement, comme le montrent les figures 12 et 13 pour constituer un genre de cardan élastiquement déformable.According to this third embodiment, the support arm (4) or more precisely its articulation on the intermediate part (9) present means of stress distribution intended to avoid having a zone where the stresses and the deformations are too important and which could lead to rupture or damage to the joint. Thus, as shown in Figures 12 and 13, the support arm (4) has near its base, section profiles which present parallel side plates. This configuration stiffens the arm (4) when working in bending and distributing the stresses in the entire joint which includes two arm portions (31a, 31b) which each have deformable side plates elastically arranged orthogonally, as shown in the figures 12 and 13 to constitute a kind of elastically deformable cardan.

    Le système de butée (22) destiné à retenir le bras support (4) dans sa position armée de précontrainte est constitué par un cran d'accrochage (220) formé d'un appui horizontal (220a) et d'un rebord vertical (220b).The stop system (22) for retaining the support arm (4) in its armed position of prestressing is constituted by a notch attachment (220) formed by a horizontal support (220a) and a flange vertical (220b).

    Selon les différents modes de réalisation décrits, le dispositif d'extraction est constitué par une pièce en forme de bague annulaire; toutefois selon d'autres modes de réalisation non représentés, le dispositif peut être réalisé en plusieurs pièces. De plus, la ou les pièces constitutives du dispositif d'extraction pourraient avoir une forme différente de la forme de la bague annulaire et posséder une forme de secteur ou autre par exemple. Par ailleurs, selon le mode de réalisation préféré, les moyens de fixation de la pièce annulaire sont constitués par le rebord périphérique destiné à être serti entre le couvercle et la paroi périphérique de la canette, ledit rebord constituant également les moyens d'étanchéité du dispositif, cependant il va de soi que les moyens de fixation pourraient présenter une configuration différente. Ainsi, la pièce annulaire pourrait par exemple ne pas être munie d'un rebord périphérique mais être fixée par coincement dans la partie supérieure de la canette qui présente une forme légèrement tronconique.According to the various embodiments described, the device extraction consists of a piece in the form of an annular ring; however according to other embodiments not shown, the device can be made in several pieces. In addition, the part (s) constituting the extraction device could have a shape different from the shape of the annular ring and have a shape of sector or other for example. Furthermore, according to the embodiment preferred, the means of fixing the annular part are constituted by the peripheral rim intended to be crimped between the cover and the wall peripheral of the can, said rim also constituting the means sealing of the device, however it goes without saying that the means of attachment could have a different configuration. So the room ring could for example not have a rim peripheral but be fixed by wedging in the upper part of the bobbin which has a slightly frustoconical shape.

    On notera que la paille (2), constituée de deux portions de paille, à savoir, une portion externe (20a) dans laquelle coulisse une portion .interne (20b), est avantageusement retenue par les moyens de retenue (10) par sa portion interne (20b), tandis que l'extrémité supérieure de la portion externe (20a) est en appui sur la bordure inférieure de la portion de tube (10) constituant lesdits moyens de retenue, tel que cela est illustré à la figure 14. Ajoutons que la portion de tube (10) est avantageusement fendue pour lui donner l'élasticité suffisante pour assurer le bon maintien de la paille.It will be noted that the straw (2), consisting of two portions of straw, namely, an outer portion (20a) in which a portion slides internal (20b), is advantageously retained by the retaining means (10) by its internal portion (20b), while the upper end of the external portion (20a) is supported on the lower edge of the portion of tube (10) constituting said retaining means, as illustrated in Figure 14. Let’s add that the tube portion (10) is advantageously split to give it sufficient elasticity to ensure good support straw.

    Ajoutons que le dispositif d'extraction (1) en position armée avec la paille (2) constitue lors du montage un sous-ensemble (100) destiné à venir se clipser dans le couvercle (16) pour y être retenu, de façon à constituer un ensemble (160) destiné à être introduit dans le récipient (3) avant sertissage, tel que cela est illustré à la figure 15. Le clipsage assurant le maintien du dispositif (1) dans le couvercle (16) avant la mise en place de l'ensemble (160) est réalisé grâce au léger bourrelet (161) prévu à la périphérie dudit couvercle. Notons aussi qu'il est prévu des moyens pour indexer la position angulaire relative du couvercle (16) avec le dispositif (1) de l'invention permettant de positionner le dispositif (1) dans une bonne position angulaire par rapport audit couvercle (16), afin que la paille, une fois libérée, fasse saillie et apparaisse au niveau du trou fait par la languette prédécoupée (7). Add that the extraction device (1) in the armed position with the straw (2) constitutes during assembly a sub-assembly (100) intended for clip into the cover (16) to be retained, so as to constitute an assembly (160) intended to be introduced into the container (3) before crimping, as illustrated in Figure 15. Clipping ensuring maintaining the device (1) in the cover (16) before installation of the assembly (160) is produced by means of the light bead (161) provided in the periphery of said cover. It should also be noted that means are provided for index the relative angular position of the cover (16) with the device (1) of the invention enabling the device (1) to be positioned in a good angular position relative to said cover (16), so that the straw, once released, protrudes and appears at the hole made by the precut tab (7).

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
