Description

La présente invention concerne un procédé de mise en place dans un récipient du type cannette d'un dispositif d'extraction automatique de paille, et son dispositif associé.The present invention relates to a method of placing an automatic straw extraction device in a can-type container, and its associated device.

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, cardboard packaging that 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 disadvantage for the user of being either unhygienic when one wants to drink from the container, or 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 cardboard packaging used for various and varied beverages such as beers, soft drinks, fruit juice or milk, these are very unhygienic. Indeed, from their places of production at the time when the drink was packaged, these are transported and unloaded without any specific hygiene measure, then sold to the consumer by a retailer who stores them without special hygiene precautions and the manipulate manually. During these various manipulations, it can deposit on the walls of the containers various microbes, viruses, bacteria or dust which the consumer will absorb when he affixes his 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 problems, the consumer may be hampered during the absorption of the drink by problems of untimely flow most often causing stains on his clothes.

Il a donc été développé un dispositif d'extraction automatique d'une paille destiné à équiper les cannettes cylindriques métalliques du type comprenant un récipient fermé par un couvercle serti qui comprend des moyens d'ouverture constitués d'un anneau poussoir destiné à déplacer vers l'intérieur de la cannette une languette prédécoupée.It has therefore been developed an automatic straw extraction device intended to equip metallic cylindrical cans of the type comprising a container closed by a crimped cover which comprises opening means constituted by a push ring intended to move towards the inside the can a pre-cut tab.

Un tel dispositif d'extraction est, par exemple, décrit dans le brevet français publié sous le numéro 2 772 731 et comprend un organe support de paille constitué par un bras de retenue élastique déformable, dont l'une des extrémités est reliée à un anneau périphérique et l'autre comprend des moyens de retenu pour la paille. L'anneau périphérique est destiné à être pris en sandwich entre le couvercle et plus particulièrement sa gorge de sertissage et la bordure périphérique supérieure du récipient, tandis que le bras de retenue est mis sous tension avant sa mise en place par déplacement et mis en appui sur une butée fixe solidaire de l'anneau périphérique. Un tel procédé qui consiste à déformer le bras avant sa mise en place sous le couvercle nécessite une chaîne de montage complexe, coûteuse et peu fiable, surtout compte tenu des cadences importantes de remplissage imposéesSuch an extraction device is, for example, described in the French patent published under the number 2 772 731 and comprises a straw support member constituted by a deformable elastic retaining arm, one of the ends of which is connected to a ring peripheral and the other includes means for retaining straw. The peripheral ring is intended to be sandwiched between the cover and more particularly its crimping groove and the upper peripheral edge of the container, while the retaining arm is tensioned before being put in place by displacement and supported. on a fixed stop secured to the peripheral ring. Such a method which consists in deforming the arm before it is placed under the cover requires a complex, expensive and unreliable assembly line, especially given the high filling rates imposed

Un dispositif selon le préambule de la revendication 1 est connu du document US-A-4 792 083.A device according to the preamble of claim 1 is known from document US-A-4,792,083.

La présente invention se propose donc de résoudre ces inconvénients en proposant un dispositif sans butée fixe pour le bras de retenue de paille mis en déformation et son procédé de mise en oeuvre.The present invention therefore proposes to resolve these drawbacks by proposing a device without a fixed stop for the straw retaining arm deformed and its method of implementation.

Ainsi, selon l'invention, le procédé de mise en place dans une cannette comprenant un récipient fermé par un couvercle d'un dispositif d'extraction automatique d'une paille du type comprenant un organe support de paille constitué par un bras de retenue déformable élastiquement destiné à être mis sous tension par déformation élastique, ledit bras comprenant un tube de retenue pour la paille ainsi qu'un bras d'actionnement destiné à être activé et déplacé par l'opercule lors de l'ouverture de la cannette, est caractérisé en ce qu'il consiste à mettre sous tension ledit bras par action directe ou indirecte du couvercle lors de l'accouplement dudit couvercle avec ledit dispositif.Thus, according to the invention, the method of placing in a can comprising a container closed by a lid of an automatic device for extracting a straw of the type comprising a straw support member constituted by a deformable retaining arm elastically intended to be tensioned by elastic deformation, said arm comprising a straw holding tube as well as an actuating arm intended to be activated and moved by the cover when the can is opened, is characterized in that it consists in energizing said arm by direct or indirect action of the cover when coupling said cover with said device.

Selon des caractéristiques complémentaires, le procédé comprend les étapes préalables suivantes :

  • a- fixer la paille au bras de retenu pour constituer un sous-ensemble intermédiaire, à savoir, le sous-ensemble paille-dispositif d'extraction ;
  • b- accouplement du sous-ensemble intermédiaire avec le couvercle pour constituer un sous-ensemble de fermeture ; et les étapes complémentaires suivantes :
  • c- remplissage du récipient avec la boisson désirée ;
  • d- mise en place du sous-ensemble de fermeture dans le récipient ;
  • e- sertissage du couvercle sur le récipient.
According to additional characteristics, the method comprises the following preliminary steps:
  • a- attach the straw to the retaining arm to constitute an intermediate sub-assembly, namely, the straw-extraction sub-assembly;
  • b- coupling of the intermediate sub-assembly with the cover to constitute a closing sub-assembly; and the following additional steps:
  • c- filling the container with the desired drink;
  • d- installation of the closure sub-assembly in the container;
  • e- crimping of the lid on the container.

Selon une autre caractéristique, le procédé consiste à mettre sous tension le bras de retenue par action du couvercle sur une saillie solidaire du bras de retenue, soit sur la paille retenue par le bras.According to another characteristic, the method consists in tensioning the retaining arm by action of the cover on a projection integral with the retaining arm, ie on the straw retained by the arm.

L'invention concerne aussi le dispositif d'extraction d'une paille destiné à mettre en oeuvre le procédé qui comporte les caractéristiques selon la revendication 1.The invention also relates to the device for extracting a straw intended to carry out the method which comprises the characteristics according to claim 1.

Selon une caractéristique complémentaire, les moyens de retenue de la paille sont constitués par une portion de tube de retenue (10).According to an additional characteristic, the straw retaining means consist of a portion of retaining tube (10).

Selon d'autres caractéristiques, le dispositif est réalisé en une seule pièce injectée en matière plastique, tandis que la bague annulaire comprend une succession de lèvres déformables qui sont prises en sandwich de façon périphérique lors du sertissage de la cannette entre le couvercle et plus particulièrement sa gorge de sertissage et la bordure périphérique supérieure de l'ouverture du récipient.According to other characteristics, the device is made in a single piece of plastic material, while the annular ring comprises a succession of deformable lips which are sandwiched peripherally during the crimping of the can between the lid and more particularly its crimping groove and the upper peripheral edge of the container opening.

Selon un mode d'exécution préféré du dispositif, la liaison élastique du bras de retenue avec l'anneau périphérique est réalisée par la succession de deux zones déformables élastiquement : une première zone de déformation permettant au bras de retenue de se déplacer en pivotement horizontal autour d'un axe vertical de pivotement, et une deuxième zone de déformation distincte de la première zone de déformation permettant au bras de se déplacer en pivotement vertical autour d'un axe horizontal de pivotement.According to a preferred embodiment of the device, the elastic connection of the retaining arm with the peripheral ring is carried out by the succession of two elastically deformable zones: a first deformation zone allowing the retaining arm to move in horizontal pivoting around a vertical pivot axis, and a second deformation zone distinct from the first deformation zone allowing the arm to move in a vertical pivot around a horizontal pivot axis.

D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawings which are given only by way of nonlimiting examples.

Le dispositif d'extraction est réalisé avantageusement en une seule pièce injectée en matière plastique, tandis que la bague annulaire (9) comprend une succession de lèvres déformables (15) qui sont prises en sandwich de façon périphérique lors du sertissage de la cannette entre le couvercle (14) et plus particulièrement sa gorge de sertissage et la bordure périphérique supérieure de l'ouverture du récipient comme cela apparaît à la figure 6a et à la figure 11a.The extraction device is advantageously made in a single piece of plastic material, while the annular ring (9) comprises a succession of deformable lips (15) which are sandwiched peripherally during the crimping of the can between the cover (14) and more particularly its crimping groove and the upper peripheral edge of the opening of the container as shown in FIG. 6a and in FIG. 11a.

Dans un premier mode d'exécution du dispositif d'extraction (1) représenté aux figures 3 à 7, les moyens de retenue (10) de la paille sont prolongés vers le haut par une saillie de mise en déformation du bras (11) qui s'étend vers le haut.In a first embodiment of the extraction device (1) shown in Figures 3 to 7, the retaining means (10) of the straw are extended upward by a projection for deformation of the arm (11) which extends upwards.

Ladite saillie (11) est constituée par une portion de paroi cylindrique dont l'extrémité supérieure (12) est destinée à venir en butée sur la paroi inférieure (13) du couvercle (14) lors de son accouplement avec ledit dispositif, comme cela est illustré aux figures 6, et 16 et, bien entendu, lors du sertissage du couvercle, provoquant ainsi la mise en déformation vers le bas selon F du bras (8), tel que cela est illustré à la figure 6 et à la figure 16.Said projection (11) is constituted by a cylindrical wall portion whose upper end (12) is intended to abut on the lower wall (13) of the cover (14) when it is coupled with said device, as is illustrated in Figures 6, and 16 and, of course, when crimping the cover, thus causing deformation down along F of the arm (8), as illustrated in FIG. 6 and in FIG. 16.

Dans un deuxième mode d'exécution du dispositif d'extraction (1), le bras de retenue (8), et notamment ses moyens de retenue (10), ne comprend pas de saillie de mise en déformation. Selon cette variante, la mise en déformation du bras se fait par action directe du couvercle sur la paille. Par ailleurs, ledit bras (8) comprend un bras d'actionnement (18) destiné à être activé et déplacé par l'opercule (5) lors de l'ouverture de la cannette. Dans cette variante, la liaison élastique du bras de retenue (8) avec l'anneau périphérique (9) est réalisée par la succession de deux zones déformables élastiquement : une première zone de déformation (16) permettant au bras de retenue (8) de se déplacer en pivotement horizontal autour d'un axe vertical de pivotement (XX'), et une deuxième zone de déformation (17), distincte de la première zone de déformation (15), permettant au bras (8) de se déplacer en pivotement vertical autour d'un axe horizontal de pivotement (YY'). On notera que la deuxième zone de déformation (17) est un profil plat déformable, mais elle pourrait avoir toute autre forme et notamment celle illustrée à la figure 25.In a second embodiment of the extraction device (1), the retaining arm (8), and in particular its retaining means (10), does not include a deformation projection. According to this variant, the arm is deformed by direct action of the cover on the straw. Furthermore, said arm (8) comprises an actuating arm (18) intended to be activated and moved by the cover (5) when the can is opened. In this variant, the elastic connection of the retaining arm (8) with the peripheral ring (9) is produced by the succession of two elastically deformable zones: a first deformation zone (16) allowing the retaining arm (8) to move in horizontal pivoting around a vertical pivot axis (XX '), and a second deformation zone (17), distinct from the first deformation zone (15), allowing the arm (8) to move in pivoting vertical around a horizontal pivot axis (YY '). It will be noted that the second deformation zone (17) is a deformable flat profile, but it could have any other shape and in particular that illustrated in FIG. 25.

Dans les deux modes d'exécution du dispositif d'extraction (1), on notera qu'en position de non contrainte de repos tel qu'illustré aux figures 3, 4, 5, 7, 8, 9, 10, 12, 13, 14, 15, 19, 20 et 21, le bras de retenue (8) s'étend de l'anneau périphérique vers l'intérieur sensiblement horizontalement, du moins dans un plan sensiblement parallèle au plan général (H) dudit anneau (9).In the two embodiments of the extraction device (1), it will be noted that in the non-resting rest position as illustrated in FIGS. 3, 4, 5, 7, 8, 9, 10, 12, 13 , 14, 15, 19, 20 and 21, the retaining arm (8) extends from the peripheral ring inward substantially horizontally, at least in a plane substantially parallel to the general plane (H) of said ring (9 ).

Par contre, en position active de précontrainte, tel qu'illustré aux figures 6, 11, 16, 17, 22, 23 et 24, le bras de retenue (8) forme avec le plan général (H) de l'anneau périphérique (9) un angle aigu (A) compris entre 20 et 60 degrés et, par exemple, 40 degrés.On the other hand, in the active prestressing position, as illustrated in FIGS. 6, 11, 16, 17, 22, 23 and 24, the retaining arm (8) forms with the general plane (H) of the peripheral ring ( 9) an acute angle (A) of between 20 and 60 degrees and, for example, 40 degrees.

Selon le procédé de mise en place du dispositif d'extraction (1) selon l'invention, le bras de retenue (8) est sollicité élastiquement vers le bas selon F, de façon à ce que, lors de l'ouverture, cette élasticité soit restituée pour faire extraire la paille (2) hors de l'ouverture, tel que cela est illustré aux figures 2, 6 et 11.According to the method of fitting the extraction device (1) according to the invention, the retaining arm (8) is resiliently biased downward along F, so that, when opened, this elasticity is returned to extract the straw (2) out of the opening, as illustrated in Figures 2, 6 and 11.

La mise sous contrainte du bras se fait au moment de l'accouplement du couvercle (14) avec le dispositif (1) tel que cela est illustré aux figures 6, 11, 16, 17, 22 et 23 par action directe ou indirecte dudit couvercle sur le bras de retenue.The arm is placed under stress when the cover (14) is coupled with the device (1) as illustrated in FIGS. 6, 11, 16, 17, 22 and 23 by direct or indirect action of said cover on the retaining arm.

Avec le premier mode d'exécution du dispositif (1), la paroi inférieure (13) du couvercle (14) sollicite le bras de retenue (8) en précontrainte élastique vers le bas par son action directe sur l'extrémité (12) de la saillie de mise en déformation du bras (11).With the first embodiment of the device (1), the lower wall (13) of the cover (14) biases the retaining arm (8) in elastic preload downwards by its direct action on the end (12) of the deformation projection of the arm (11).

Avec le deuxième mode d'exécution du dispositif (1), la paroi inférieure (13) du couvercle (14) sollicite le bras de retenue (8) en précontrainte élastique vers le bas par son action directe sur l'extrémité (20) de la paille (2) retenue par la portion tubulaire de retenue (10).With the second embodiment of the device (1), the lower wall (13) of the cover (14) biases the retaining arm (8) in elastic preload downwards by its direct action on the end (20) of the straw (2) retained by the tubular retaining portion (10).

On a compris qu'avec le premier mode d'exécution du dispositif d'extraction (1), lors de l'ouverture de la cannette, l'opercule (5) libère le bras de retenue (8) de la paille (2) qui, ayant été précontraint élastiquement, revient à sa position inactive pour entraîner avec lui l'extrémité de la paille qui fait alors saillie par l'orifice (6).It has been understood that with the first embodiment of the extraction device (1), when the can is opened, the cover (5) releases the retaining arm (8) from the straw (2) which, having been elastically prestressed, returns to its inactive position to carry with it the end of the straw which then projects through the orifice (6).

Avec le deuxième mode d'exécution du dispositif d'extraction (1), l'extrémité (150) du bras d'actionnement (15) est disposée dans la trajectoire de l'opercule (5). Aussi, lors de l'ouverture de la cannette, l'opercule (5) agit sur le bras d'actionnement (15) pour faire pivoter l'ensemble qu'il constitue avec le bras de retenue (8) autour de l'axe (XX') et ainsi placer l'extrémité de la paille dans la zone de l'ouverture (6), la paille faisant immédiatement saillie par cette ouverture par libération de la précontrainte.With the second embodiment of the extraction device (1), the end (150) of the actuating arm (15) is arranged in the path of the cover (5). Also, when the can is opened, the cover (5) acts on the actuating arm (15) to pivot the assembly which it constitutes with the retaining arm (8) around the axis. (XX ') and thus place the end of the straw in the area of the opening (6), the straw immediately protruding through this opening by releasing the prestress.

La mise en oeuvre du procédé consiste dans les étapes préalables suivantes :

  • a- fixer la paille au bras de retenue par introduction de la paille dans le tube de retenue (10) pour constituer un sous-ensemble intermédiaire (30), à savoir, le sous-ensemble paille (2)-dispositif d'extraction (1).
    Lors de cette opération, il y a lieu de prendre soin de faire dépasser la paille vers le haut d'une hauteur suffisante (L) comprise entre 10 et 25 millimètres (voir figures 13, 14 et figures 19 et 20).
  • b- accouplement du sous-ensemble intermédiaire (30) avec le couvercle, pour constituer un sous-ensemble de fermeture (31).
    Dans cette étape, le sous-ensemble (30) est engagé sous le couvercle (14) et clipsé avec ce dernier par coopération de la succession de lèvres (15) avec la gorge périphérique (31) du couvercle (voir figures 15, 16 et figures 21 et 22). Bien entendu, la mise en place du dispositif avec sa paille avec le couvercle se fait avec une orientation angulaire relative déterminée. Lors du clipsage du sous-ensemble (30) avec le couvercle, la paroi inférieure (13) de ce dernier force directement ou indirectement le bras de retenue (8) vers le bas pour le placer dans la position de précontrainte, tel qu'illustré aux figures 6, 16 et aux figures 11 et 22.
The implementation of the process consists of the following preliminary steps:
  • a- attach the straw to the retaining arm by introducing the straw into the retaining tube (10) to constitute an intermediate sub-assembly (30), namely, the straw sub-assembly (2) -extraction device ( 1).
    During this operation, care should be taken to make the straw protrude upwards by a sufficient height (L) of between 10 and 25 millimeters (see Figures 13, 14 and Figures 19 and 20).
  • b- coupling of the intermediate sub-assembly (30) with the cover, to constitute a closing sub-assembly (31).
    In this step, the sub-assembly (30) is engaged under the cover (14) and clipped with the latter by cooperation of the succession of lips (15) with the peripheral groove (31) of the cover (see FIGS. 15, 16 and Figures 21 and 22). Of course, the installation of the device with its straw with the cover is done with a determined relative angular orientation. When the sub-assembly (30) is clipped onto the cover, the lower wall (13) of the latter forces the retaining arm (8) directly or indirectly downwards to place it in the preloaded position, as illustrated in Figures 6, 16 and Figures 11 and 22.

Lors de l'embouteillage proprement dit il est procédé aux étapes complémentaires successives suivantes :

  • c- remplissage du récipient (3) avec la boisson désirée ;
  • d- mise en place du sous-ensemble de fermeture dans le récipient, tel que cela est illustré aux figures 17,18 et aux figures 23 et 24 ;
  • e- sertissage du couvercle (34) sur le récipient (3).
During the actual bottling, the following successive additional steps are carried out:
  • c- filling the container (3) with the desired drink;
  • d- positioning of the closure sub-assembly in the container, as illustrated in Figures 17,18 and Figures 23 and 24;
  • e- crimping the cover (34) on the container (3).

Dans la variante illustrée à la figure 25, la deuxième zone de déformation (17) est un profil creux ouvert, notamment en forme d'oméga afin de donner à ladite zone une élasticité appropriée.In the variant illustrated in FIG. 25, the second deformation zone (17) is an open hollow profile, in particular in the shape of an omega, in order to give said zone an appropriate elasticity.

La paille (2) utilisée est avantageusement une paille télescopique, flexée, c'est-à-dire qui comprend un accordéon de déformation.The straw (2) used is advantageously a telescopic straw, flexed, that is to say which comprises a deformation accordion.

On notera que le dispositif peut comprendre une rampe de guidage (90) pour l'extrémité de la paille, tel que cela apparaît aux figures 9,10 et 25.It will be noted that the device may include a guide ramp (90) for the end of the straw, as shown in FIGS. 9, 10 and 25.

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 embodiments described and represented by way of examples, but it also includes all the technical equivalents as well as their combinations.
