Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne le domaine des récipients, généralement des bouteilles, dont l'orifice est doté d'un verseur, typiquement dans le cas du conditionnement de liqueurs, d'apéritifs, d'alcools.The invention relates to the field of containers, generally bottles, of which the orifice is provided with a pourer, typically in the case of liquor conditioning, aperitifs, alcohols.

ETAT DE LA TECHNIQUESTATE OF THE ART

On connaít déjà différentes sortes de verseurs, associés à des capsules de bouchage, qui se distinguent notamment par leur mode de fixation au goulot du récipient et par l'élément verseur lui-même.
En ce qui concerne l'élément verseur lui-même, il peut être soit à configuration fixe, comme représenté sur les figures 1 et 2, soit à configuration variable, et notamment mobile axialement comme décrit dans les brevets FR 2.057.345, GB 922,188, US 3,217,935 et US4,569,464.
En ce qui concerne le mode de fixation au goulot du récipient, le verseur peut être emmanché à force dans le goulot, le verseur étant généralement muni de nervures circulaires d'étanchéité comme représenté sur la figure 2, et décrit dans les brevets FR 2.057.345, GB 922,188 et US 3,217,935.Various types of pourers are already known, associated with capping capsules, which are distinguished in particular by their method of attachment to the neck of the container and by the pouring element itself.
Regarding the pouring element itself, it can be either fixed configuration, as shown in Figures 1 and 2, or variable configuration, including axially movable as described in FR 2,057,345, GB 922,188 patents , US 3,217,935 and US 4,569,464.
Regarding the method of attachment to the neck of the container, the pourer can be force-fitted into the neck, the pourer being generally provided with circular sealing ribs as shown in Figure 2, and described in FR 2,057 patents. 345, GB 922,188 and US 3,217,935.

PROBLEME POSEPROBLEM

Ces verseurs sont associés à une capsule de bouchage et sont donc fixés au goulot lors du sertissage de la capsule de bouchage associée audit verseur, et cela, par application d'une force axiale exercée sur la tête de la capsule de bouchage, une force axiale relativement élevée, qui peut aller de 80 à 100 daN, étant nécessaire pour que ledit verseur soit fixé irréversiblement au goulot.
Dans ces conditions, compte tenu du niveau de cette force, certaines capsules de bouchage peuvent être endommagées, notamment par flambage de la jupe ou altération des moyens d'ouverture facile.
Le problème à résoudre est donc d'avoir un verseur dont la fixation au goulot ne nécessite qu'une force axiale relativement faible, typiquement inférieure à 20 daN, de manière à pouvoir associer ledit verseur à tout type de capsule de bouchage, même les moins résistantes mécaniquement, compte tenu de la tendance permanente à réduire les épaisseurs des matériaux et le poids des emballages.These pourers are associated with a closure cap and are therefore attached to the neck during crimping of the closure cap associated with said pourer, and this, by applying an axial force exerted on the head of the closure cap, an axial force relatively high, which can range from 80 to 100 daN, being necessary for said pourer is irreversibly fixed to the neck.
Under these conditions, given the level of this force, some caps capping may be damaged, including buckling of the skirt or alteration means easy opening.
The problem to be solved is therefore to have a pourer whose attachment to the neck requires only a relatively low axial force, typically less than 20 daN, so as to associate said pourer to any type of capping cap, even the least mechanically resistant, given the permanent tendency to reduce the thickness of materials and the weight of packaging.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Selon l'invention, le verseur, destiné à être associé à une capsule de bouchage et à être fixé à l'intérieur d'un goulot d'un récipient, comprend une jupe périphérique dotée d'un moyen de fixation étanche au goulot, un élément verseur, et un moyen d'assemblage temporaire dudit verseur et de ladite capsule de bouchage, et est caractérisé en ce que,

  • a) ladite jupe périphérique comprend une partie inférieure apte à subir un écartement radial assurant la fixation du verseur audit goulot,
  • b) ledit verseur comprend une pièce rigide apte à subir un déplacement axial vers le bas, à l'intérieur de ladite jupe périphérique, par passage, typiquement irréversible, d'une position dite haute H à une position stable dite basse B lors de la fixation dudit verseur et de ladite capsule audit goulot,
  • c) ledit verseur comprend un moyen de coopération de ladite partie inférieure et de ladite pièce rigide apte à transformer le déplacement axial de ladite pièce rigide en déplacement radial de ladite partie inférieure, ledit déplacement axial ne commençant qu'une fois ledit verseur placé dans ledit goulot, la force axiale exigée par le déplacement axial de ladite pièce rigide par rapport à la dite jupe périphérique étant supérieure à celle exigée pour introduire ledit verseur dans ledit goulot.
    • According to the invention, the pourer, intended to be associated with a closure cap and to be fixed inside a neck of a container, comprises a peripheral skirt provided with a neck-tight fastening means, a pouring element, and a means for temporary assembly of said pourer and said closure cap, and is characterized in that,
  • a) said peripheral skirt comprises a lower part capable of undergoing a radial spacing ensuring the attachment of the pourer to said neck,
  • b) said pourer comprises a rigid piece capable of undergoing axial downward movement, inside said peripheral skirt, by passage, typically irreversible, from a so-called high position H to a so-called low position B at the time of the fixing said pourer and said capsule to said neck,
  • c) said pourer comprises a means of cooperation of said lower part and said rigid piece adapted to transform the axial displacement of said rigid part in radial displacement of said lower part, said axial displacement starting only once said pourer placed in said neck, the axial force required by the axial displacement of said rigid part relative to said peripheral skirt being greater than that required to introduce said pourer into said neck.

    • L'invention résout le problème posé. En effet, avec les moyens de l'invention, d'une part, l'introduction de la capsule et du verseur associé dans le goulot ne requiert qu'une force FI, dite d'introduction, relativement faible, compte tenue du choix des dimensions extérieures de la jupe périphérique par rapport aux dimensions intérieures du goulot. D'autre part, le déplacement axial qui suit l'introduction du verseur dans le goulot exige certes une force axiale FD, dite de déplacement, supérieure à FI, de manière à ce que ledit déplacement axial ne puisse pas commencer avant que le verseur ne soit correctement enfoncé dans le goulot, mais cette force de déplacement FD reste très inférieure à celle nécessitée par les capsules avec verseurs de l'état de la technique.The invention solves the problem posed. Indeed, with the means of the invention, on the one hand, the introduction of the capsule and the associated pourer in the neck requires only a force F I , called introduction, relatively low, given the choice external dimensions of the peripheral skirt with respect to the internal dimensions of the neck. On the other hand, the axial displacement that follows the introduction of the pourer into the neck certainly requires an axial force F D , called displacement, greater than F I , so that said axial displacement can not begin before the pourer is not properly inserted into the neck, but this displacement force F D remains much lower than that required by the capsules with pourers of the state of the art.

    Toutes les figures sont relatives à l'invention.
    La figure 1A est une vue partielle d'une capsule (1) dotée de son insert (2) et associée à un verseur (3), en coupe axiale selon l'axe vertical (11) de la capsule, le verseur étant introduit dans le goulot (9) d'un récipient, la pièce rigide (6H) du verseur étant encore en position haute, avant fixation du verseur au goulot et donc avant tout déplacement axial de cette pièce rigide (6).
    La figure 1B est analogue à la figure 1A, mais avec la pièce rigide (6B) en position basse, à la suite de son déplacement axial.
    La figure 1C est analogue à la figure 1A et représente la capsule (1) dotée de son insert (2) et de son verseur (3) avant introduction dans le goulot (9).    All the figures relate to the invention.

    Figure 1B is similar to Figure 1A, but with the rigid part (6B) in the low position, as a result of its axial displacement.
    Figure 1C is similar to Figure 1A and shows the capsule (1) with its insert (2) and its pourer (3) before introduction into the neck (9).

    La figure 2 est analogue à la figure 1B, mais en diffère en ce que la lèvre circulaire flexible (80) est solidaire de la pièce rigide (6), et non de la jupe périphérique (4) comme sur les figures 1A et 1B.Figure 2 is similar to Figure 1B, but differs in that the circular lip flexible (80) is integral with the rigid piece (6), and not the peripheral skirt (4) as in Figures 1A and 1B.

FIGS. 5A to 6, similar to FIGS. 3A to 4B, describe other embodiments of the invention in which the rigid piece (6) bears directly against the lower part (5) and more specifically against its inner side (510). ).
    In FIGS. 5A and 5B, similar to FIGS. 3A and 3B, the rigid piece (6) is a typically cylindrical skirt, whereas in FIG. 6, similar to FIG. 5B, this rigid skirt forms a cage (63) containing a ball (630) so as to make the pourer refillable.

      Figure 8A is an exploded view in side perspective of the insert (2) and the associated pourer (3), the rigid piece (6) being in the up position (6H), before the pourer is introduced into the neck. It shows that the cage (63) comprises three arches (631) for gripping the ball (630).
      The pourer (3) is associated with the insert by means of temporary assembly means (20) and (40) borne respectively by a tongue of the insert (2), and by the upper end of the peripheral skirt ( 4).

    DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

    Selon l'invention, la partie inférieure (5) peut être rigide et être articulée par rapport à la jupe périphérique (4), typiquement grâce à une partie amincie (50) formant une charnière O et reliant la partie inférieure (5) à la jupe périphérique (4), et forme un élément articulé (51), typiquement sous forme d'un secteur angulaire d'angle  limité par les côtés extérieur OC et intérieur OD, faisant chacun respectivement un angle ΦC et ΦD par rapport à la verticale, et dans lequel la pièce rigide (6) coopère, typiquement pas son extrémité, avec la partie inférieure (5), typiquement par son côté intérieur OD, de manière à ce que ledit déplacement axial vers le bas de la pièce rigide (6) entraíne la rotation dudit élément articulé ou secteur angulaire (51), l'angle ΦC valant typiquement 0° et l'angle ΦD valant -α° avant ledit déplacement axial, l'angle ΦC valant typiquement +α° et l'angle ΦD valant 0° après ledit déplacement axial, α étant typiquement compris entre 5 et 25°.
    Par « rigide », on entend que, suite audit déplacement axiale, la partie inférieure (5) se déplace radialement en pivotant autour de la charnière O, et cela sans déformation plastique notable de cette partie inférieure (5).
    Les figures 1A et 1B, 3A et 3B, 4a et 4B, 7A, 11A et 11B illustrent ces rotations de la partie inférieure (5).     According to the invention, the lower part (5) can be rigid and articulated with respect to the peripheral skirt (4), typically thanks to a thinned portion (50) forming a hinge O and connecting the lower part (5) to the peripheral skirt (4), and forms an articulated element (51), typically in the form of an angular sector of angle  bounded by the outer sides OC and inner OD, each making an angle Φ C and Φ D respectively relative to the vertical, and in which the rigid part (6) cooperates, typically not its end, with the lower part (5), typically by its inner side OD, so that said axial displacement down the rigid part ( 6) causes rotation of said articulated element or angular sector (51), the angle Φ C being typically 0 ° and the angle Φ D equal to -α ° before said axial displacement, the angle Φ C typically being + α ° and the angle Φ D equaling 0 ° after said displacement axi al, α being typically between 5 and 25 °.
    By "rigid" is meant that, following said axial displacement, the lower portion (5) moves radially pivoting about the hinge O, and without significant plastic deformation of the lower portion (5).
    FIGS. 1A and 1B, 3A and 3B, 4a and 4B, 7A, 11A and 11B illustrate these rotations of the lower part (5).

    Selon une modalité de l'invention, la pièce rigide (6) peut coopérer avec la partie inférieure (5) par un élément rigide (72,73) formant le moyen de coopération (7) et articulé à ses extrémités X et Y, une des extrémités X étant solidaire, ou rendue solidaire, de la partie inférieure (5), l'autre extrémité Y étant solidaire, ou rendue solidaire, de la pièce rigide (6), de manière à ce que ledit déplacement axial de l'élément rigide (72,73), en faisant varier l'inclinaison dudit élément articulé (51) pour atteindre ladite position stable et en déplaçant vers le bas l'extrémité Y, repousse radialement vers l'extérieur l'extrémité X, assurant ainsi ledit passage de la position haute H à la position basse Y.
    Cette modalité est illustrée sur les figures 3A à 4B et 7A à 9B.    According to a modality of the invention, the rigid piece (6) can cooperate with the lower part (5) by a rigid element (72,73) forming the cooperation means (7) and articulated at its ends X and Y, a ends X being integral with, or made integral with, the lower part (5), the other end Y being secured to, or secured to, the rigid part (6), so that said axial displacement of the element rigid (72,73), by varying the inclination of said articulated element (51) to reach said stable position and by moving the Y end downwards, pushes the X-end radially outwardly, thus ensuring said passage from the high position H to the low position Y.
    This modality is illustrated in FIGS. 3A to 4B and 7A to 9B.

    Dans une variante de verseur illustrée sur les figures 3A, 3B et 7A, et de manière à obtenir ladite position stable, d'une part, la hauteur ZYH de ladite extrémité Y en position haute, avant ledit déplacement axial, peut être typiquement supérieure à la hauteur ZX de ladite extrémité X, alors que la hauteur ZYB de ladite extrémité Y en position basse, après ledit déplacement axial, peut être typiquement inférieure à la hauteur ZX de ladite extrémité X, et d'autre part, ledit élément rigide (73) peut présenter une section typiquement triangulaire, l'extrémité Y formant un sommet de ce triangle, de manière à ce que, en position basse, un côté adjacent (730) à ce sommet vienne en butée contre la pièce rigide (6) et limite ainsi ledit déplacement axial vers le bas.In a pourer variant illustrated in FIGS. 3A, 3B and 7A, and so as to obtain said stable position, on the one hand, the height Z YH of said end Y in the high position, before said axial displacement, can be typically greater at the height Z X of said X end, while the height Z YB of said Y end in the low position, after said axial displacement, may be typically less than the height Z X of said X end, and secondly, said rigid element (73) may have a typically triangular section, the Y end forming an apex of this triangle, so that, in the low position, an adjacent side (730) to this vertex abuts against the rigid piece ( 6) and thus limits said axial displacement downwards.

    De manière avantageuse, et comme illustré sur les figures 14 à 16C, ladite partie inférieure (5) peut comprendre, comme éléments articulés (51), des languette rigides (53) ou des talons rigides (54) régulièrement espacés et en nombre n allant de 3 à 10, et typiquement de 4 à 8, à chaque languette (53) ou talon (54) correspondant un élément rigide (72, 73) distinct. Sur les figures 14 à 16C, n est égal à 8.
    De préférence, un verrou (740) peut être angulairement intercalé entre deux dits talons rigides (54) consécutifs, grâce à une tige de verrouillage (74) analogue audit élément rigide (72,73), de manière à bloquer circulairement lesdits talons rigides par lesdits verrous lorsque ladite pièce rigide (6) est en position dite basse.     Advantageously, and as illustrated in FIGS. 14 to 16C, said lower portion (5) may comprise, as articulated elements (51), rigid tongues (53) or rigid heels (54) regularly spaced and in number n ranging from 3 to 10, and typically from 4 to 8, with each tongue (53) or heel (54) corresponding to a separate rigid member (72, 73). In FIGS. 14 to 16C, n is equal to 8.
    Preferably, a lock (740) can be angularly interposed between two said rigid heels (54) consecutive, by means of a locking rod (74) similar to said rigid element (72,73), so as to block said rigid heels circularly by said locks when said rigid piece (6) is in so-called low position.

    Comme illustré sur la figure 16C, lesdits verrous (740) et lesdits talons rigides (54) peuvent coopérer, typiquement grâce à une encoche d'encliquetage (540), de manière à renforcer la fixation du verseur (3) au goulot (9).
    Il est également avantageux que lesdits talons rigides (54) comprennent des ailettes (541), de manière à renforcer la fixation du verseur (3) audit goulot (9).    As illustrated in FIG. 16C, said locks (740) and said rigid heels (54) can cooperate, typically by means of a detent notch (540), so as to reinforce the attachment of the pourer (3) to the neck (9) .
    It is also advantageous that said rigid heels (54) comprise fins (541), so as to reinforce the attachment of the spout (3) to said neck (9).

    Dans le cas des verseurs selon les figures 3A à 4B, 7A à 9A et 14 à 16C, le verseur (3) forme de préférence une pièce monobloc.In the case of pourers according to FIGS. 3A to 4B, 7A to 9A and 14 to 16C, the pourer (3) preferably forms a single piece.

    Selon une autre modalité de l'invention, l'extrémité inférieure (61) de la pièce rigide (6) peut venir en appui direct sur un côté intérieur (510) de la partie inférieure (5), de manière à former ledit moyen de coopération. Cette modalité a été illustrée sur les figures 1A, 1B, 2, 5A, 5B, 6, 11A à 13.According to another embodiment of the invention, the lower end (61) of the rigid piece (6) can bear directly on an inner side (510) of the lower part (5), in order to form said cooperation means. This modality has been illustrated on FIGS. 1A, 1B, 2, 5A, 5B, 6, 11A to 13.

    Typiquement, la pièce rigide (6) et la jupe périphérique (4) peuvent comprendre des éléments (62, 43), mâles et femelles, coopérant et s'encliquetant irréversiblement, de manière à obtenir ladite position stable, comme illustré sur les figures 1A et 1B à titre d'exemple. En effet, quelle que soit la modalité de l'invention, il est en général préférable que le verseur reste fixé au goulot une fois placé dans ce dernier.Typically, the rigid piece (6) and the peripheral skirt (4) may comprise elements (62, 43), male and female, cooperating and irreversibly to obtain said stable position, as illustrated in FIGS. 1A and 1B as example. Indeed, whatever the modality of the invention, it is generally it is preferable that the pourer remains attached to the neck once placed in the latter.

    Il est avantageux que la capsule de bouchage (1), typiquement métallique, soit munie d'un insert (2) en matière plastique assurant l'étanchéité de la capsule de bouchage (1) et comprenant le moyen d'assemblage temporaire (20) et un moyen de déplacement axial (21) de la pièce rigide (6), ces deux moyens pouvant être partiellement confondus, le moyen d'assemblage temporaire (20), ayant typiquement la forme d'une couronne, assurant la coopération temporaire de l'insert (2), solidaire de la capsule (1), et du verseur (3), le moyen de déplacement axial (21) de l'insert étant en prise directe sur la pièce rigide (6H) en position dite haute.
    En effet, bien que les verseurs selon l'invention puissent présenter déjà, en eux-mêmes, un grand intérêt, l'intérêt le plus grand réside dans l'association d'un verseur et d'une capsule de bouchage, puisque c'est pour résoudre un problème lié à une telle association que le verseur selon l'invention a été mis au point.
    Pour le conditionneur, la capsule munie d'un verseur est utilisée sur machine d'embouteillage pratiquement comme une capsule standard non munie de verseur, et cela sans risque d'endommagement de la capsule, ce qui illustre le grand intérêt de l'invention.    It is advantageous that the closure cap (1), typically metallic, is provided with a plastic insert (2) sealing the closure cap (1) and comprising the temporary assembly means (20). and a means for axial displacement (21) of the rigid part (6), these two means being able to be partially merged, the temporary assembly means (20), typically having the shape of a crown, ensuring the temporary cooperation of the insert (2), integral with the capsule (1), and the spout (3), the axial displacement means (21) of the insert being in direct contact with the rigid piece (6H) in the so-called high position.
    Indeed, although the pourers according to the invention can already present, in themselves, a great interest, the greatest interest lies in the combination of a pourer and a capping capsule, since it is to solve a problem related to such an association that the pourer according to the invention has been developed.
    For the conditioner, the capsule with a pourer is used on a bottling machine substantially like a standard capsule without a pourer, and this without risk of damage to the capsule, which illustrates the great interest of the invention.

    La jupe périphérique (4) du verseur peut comprendre au moins une nervure circulaire (41) assurant l'étanchéité du verseur (4) avec le goulot (9), la largeur, le nombre et la flexibilité des nervures (41) étant choisi pour obtenir une friction assez élevée avec le goulot pour assurer ladite étanchéité, et cependant assez basse pour que la jupe périphérique (4) puisse, lors de la fixation du verseur, et de la capsule de bouchage associée, au goulot (9), être introduite à sa place définitive dans le goulot (9), par appui axial sur la capsule, avant que ne commence ledit déplacement axial vers le bas de la pièce rigide (6). La plupart de figures - sauf la figure 13, illustrent cette modalité.
    La friction peut être choisie de manière à ce que la force FI pour introduire le verseur et sa jupe périphérique dans le goulot soit typiquement inférieure à 10 daN, et qu'une force FD, supérieure à FI, typiquement supérieure à 10 daN, et de préférence comprise entre 10 et 20 daN, soit nécessaire pour assurer ledit déplacement axial.    The peripheral skirt (4) of the pourer may comprise at least one circular rib (41) sealing the pourer (4) with the neck (9), the width, the number and the flexibility of the ribs (41) being chosen for to obtain a rather high friction with the neck to ensure said sealing, and yet low enough so that the peripheral skirt (4) can, during the attachment of the pourer, and the associated closure cap, to the neck (9), be introduced in its final place in the neck (9), by axial support on the capsule, before the said axial movement towards the bottom of the rigid piece (6) begins. Most figures - except Figure 13, illustrate this modality.
    The friction can be chosen so that the force F I to introduce the pourer and its peripheral skirt into the neck is typically less than 10 daN, and a force F D , greater than F I , typically greater than 10 daN , and preferably between 10 and 20 daN, is necessary to ensure said axial displacement.

    Comme illustré sur les figures, la jupe périphérique (4) peut comprendre un rebord supérieur (42) venant en appui sur tout ou partie du buvant (90) du goulot (9) lorsque la jupe périphérique (4) du verseur (3) est mise en place dans le goulot (9). Ainsi, il est commode que le verseur, soumis à la force axiale FI, vienne en butée contre le buvant (90), de manière à éviter de contrôler le déplacement axial de la jupé périphérique (4) du verseur.As illustrated in the figures, the peripheral skirt (4) may comprise an upper rim (42) resting on all or part of the rim (90) of the neck (9) when the peripheral skirt (4) of the pourer (3) is placed in the neck (9). Thus, it is convenient that the pourer, subjected to the axial force F I , abuts against the rim (90), so as to avoid controlling the axial displacement of the peripheral skirt (4) of the pourer.

    L'élément verseur peut être solidaire soit de la jupe périphérique (4), soit de la pièce rigide (6). Il a été représenté solidaire de la jupe périphérique (4) sur l'ensemble des figures concernées, sauf sur la figure 2 où il a été représenté solidaire de la pièce rigide (6). The pouring element may be integral with either the peripheral skirt (4) or the part rigid (6). It has been shown integral with the peripheral skirt (4) on all the figures concerned, except in Figure 2 where it has been shown attached to the rigid part (6).

    Comme illustré par exemple sur les figures 1A et 1B, l'élément verseur peut comprendre une lèvre circulaire flexible (8), à l'état fléchi (8F) ou plaqué, typiquement contre le buvant du goulot, lorsque le goulot (9) est fermé par la capsule de bouchage (1), ou à l'état déployé (8D) lorsque le verseur (3) doit être utilisé, la capsule de bouchage (1), typiquement à vis, ayant été enlevée.As illustrated for example in FIGS. 1A and 1B, the pouring element can comprise a flexible circular lip (8), in the bent (8F) or plated state, typically against the rim of the neck, when the neck (9) is closed by the capping capsule (1), or in the expanded state (8D) when the pourer (3) is to be used, the capsule of capping (1), typically screw, having been removed.

    Comme illustré sur les figures 10A et 10B, l'insert (2) peut comprendre, outre une lèvre de solidarisation (22) de l'insert (2) avec la partie métallique (10) de la capsule (1), une lèvre d'étanchéité (23) orientée vers l'intérieur du goulot (9) et destinée à prendre appui sur le buvant (90) du goulot (9) ou sur la lèvre circulaire (8F) formant l'élément verseur si ce dernier s'étend sur ledit buvant, de manière à fermer de manière étanche le goulot (9).
    Comme illustré sur les figures 11A et 11B, la lèvre circulaire flexible (8) peut présenter à l'état déployée (8D) un diamètre extérieur qui est inférieur au diamètre intérieur de la lèvre d'étanchéité (23), de manière à ce que, lorsque le goulot (9) est fermé par la capsule de bouchage (1), la lèvre circulaire passe à l'état fléchi (8F) en se plaquant contre la lèvre d'étanchéité (23), elle-même étant alors plaquée contre le buvant (90) du goulot.    As illustrated in FIGS. 10A and 10B, the insert (2) may comprise, in addition to a securing lip (22) of the insert (2) with the metal part (10) of the capsule (1), a lip of sealing (23) directed towards the inside of the neck (9) and intended to bear on the rim (90) of the neck (9) or on the circular lip (8F) forming the pouring element if the latter extends on said rim, so as to seal the neck (9).
    As illustrated in FIGS. 11A and 11B, the flexible circular lip (8) may have in the expanded state (8D) an outside diameter which is smaller than the inside diameter of the sealing lip (23), so that when the neck (9) is closed by the closure cap (1), the circular lip moves to the bent state (8F) by pressing against the sealing lip (23), which itself is pressed against the water (90) of the neck.

    Selon une variante de l'invention illustrée sur la figure 13, tout ou partie de l'étanchéité dudit moyen de fixation étanche du verseur (3) au goulot (9) peut être assurée par au moins une nervure externe (512) portée par la partie inférieure (5).According to a variant of the invention illustrated in FIG. 13, all or part of the seal said sealing means of the pourer (3) to the neck (9) can be provided by the less an external rib (512) carried by the lower part (5).

    Selon une autre variante de l'invention illustrée sur les figures 12A et 12B, la jupe périphérique (4) et la pièce rigide (6) peuvent coopérer selon des surfaces tronconiques (44,64), de manière à ce que ledit déplacement axial conduise à un écartement radial de la jupe périphérique (4), de manière à augmenter la fixation et/ou l'étanchéité entre le goulot (9) et le verseur (3).According to another variant of the invention illustrated in FIGS. 12A and 12B, the skirt device (4) and the rigid part (6) can cooperate on frustoconical surfaces (44, 64), so that said axial displacement results in a radial spacing of the peripheral skirt (4), so as to increase the fixing and / or the sealing between the neck (9) and the spout (3).

    Sur l'ensemble des figures, les fonctions de l'insert (2) est notamment d'assurer la fermeture étanche du goulot, ainsi que l'assemblage temporaire du verseur. Cependant, l'insert (2) peut également être fileté, et dans ce cas, il comprend un jupe filetée destinée à coopérer avec le filetage du goulot.In all the figures, the functions of the insert (2) are in particular to ensure the tight closure of the neck, as well as the temporary assembly of the pourer. However, the insert (2) can also be threaded, and in this case, it comprises a threaded skirt intended to cooperate with the thread of the neck.

    Selon une autre modalité de l'invention illustrée sur la figure 6 et les figures 7A à 9B, la pièce rigide (6) peut former une cage (63) pour une bille (630), de manière à former un verseur irremplissable (3I).According to another embodiment of the invention illustrated in FIG. 6 and FIGS. 7A to 9B, the rigid piece (6) can form a cage (63) for a ball (630), so as to form a non-refillable pourer (3I).

    Un autre objet de l'invention est constitué par une capsule de bouchage solidarisé temporairement à un verseur selon l'invention, par la coopération d'un moyen d'assemblage temporaire (20) porté par l'insert (2), et d'un moyen d'assemblage temporaire (40,60) porté par le verseur (3). Un tel objet est représenté sur la figure 1C.Another object of the invention is constituted by a closure cap secured temporarily to a pourer according to the invention, by the cooperation of a means temporary assembly (20) carried by the insert (2), and an assembly means temporary (40,60) carried by the pourer (3). Such an object is shown in FIG. 1C.

    La coque de la capsule est typiquement métallique (10), mais l'invention n'est pas limitée à ce type de matériau. Elle pourrait être également en matière plastique.
    Les inserts (2) et les verseurs (3) peuvent être en matière plastique moulée. Ils peuvent être en toute matière plastique apte à être moulée, choisie en fonction de son coût et des caractéristiques mécaniques requises, mais typiquement en polyoléfine, tel que PE, PP, ou en d'autres matériaux thermoplastique, tels que PA, PET, PS (éventuellement modifié pour avoir une souplesse suffisante), ou encore en matériau élastomère tels que SBS ou autres caoutchoucs synthétiques. Les inserts et verseurs peuvent être formés d'une seule pièce ou monoblocs, sauf lorsque deux pièces distinctes sont prévues, comme par exemple avec les verseurs des figures 1A à 2 et 5A à 6. Dans ce cas, de préférence, on peut avoir la jupe périphérique (4) et sa partie inférieure (5) en matériau élastomère, la partie inférieure (5) étant dans ce cas rendue rigide par l'épaisseur du matériau, alors que la pièce rigide (6) sera en un matériau de plus grande dureté, rigidité et autres caractéristiques mécaniques, par exemple en PP, de manière à garantir une fixation étanche de la jupe périphérique (4) au goulot (9), l'étanchéité requise ici visant à ce que, lorsque le verseur est utilisé, la totalité du liquide versé s'écoule bien au travers de l'élément verseur (8), et cela, sans écoulement de liquide ou suintement entre la paroi intérieure du goulot et le verseur. Par contre, lorsque les verseurs sont formés d'une pièce monobloc et présentent des charnières pour permettre l'articulation d'un moyen de coopération (7) entre la partie inférieure (5) de la jupe périphérique et la pièce rigide (6) du verseur, comme dans le cas des verseurs des figures 3A à 4B, 7A et 8A, les charnières sont obtenues par amincissement de paroi et, réciproquement, les parties les plus rigides, comme la pièce rigide (6), sont obtenues en jouant sur l'épaisseur du matériau.    The shell of the capsule is typically metallic (10), but the invention is not limited to this type of material. It could also be plastic.
    The inserts (2) and the pourers (3) can be molded plastic. They can be in any plastic material capable of being molded, chosen according to its cost and the mechanical characteristics required, but typically in polyolefin, such as PE, PP, or other thermoplastic materials, such as PA, PET, PS (optionally modified to have sufficient flexibility), or elastomeric material such as SBS or other synthetic rubbers. The inserts and pourers can be formed in one piece or monoblocks, except when two separate parts are provided, such as with the pourers of Figures 1A to 2 and 5A to 6. In this case, preferably, we can have the peripheral skirt (4) and its lower part (5) of elastomeric material, the lower part (5) being in this case made rigid by the thickness of the material, whereas the rigid part (6) will be made of a larger material hardness, rigidity and other mechanical characteristics, for example in PP, so as to ensure a tight attachment of the peripheral skirt (4) to the neck (9), the sealing required here so that, when the pourer is used, the all poured liquid flows well through the pouring element (8), and this, without liquid flow or seep between the inner wall of the neck and the pourer. By cons, when the pourers are formed of a single piece and have hinges to allow the articulation of a means of cooperation (7) between the lower portion (5) of the peripheral skirt and the rigid part (6) of the pourer, as in the case of the pourers of Figures 3A to 4B, 7A and 8A, the hinges are obtained by wall thinning and, conversely, the more rigid parts, such as the rigid part (6), are obtained by playing on the thickness of the material.

    On peut aussi former des verseurs ou des éléments de verseur (4 et 5) monobloc en au moins deux matériaux différents par surmoulage. Ainsi, par exemple, l'élément verseur (8) et/ou la partie inférieure (5) formant un secteur angulaire (51) peuvent être en un matériau différent de celui constituant la jupe périphérique (4).It is also possible to form pourers or pourer elements (4 and 5) in one piece at least two different materials by overmolding. So, for example, the pouring element (8) and / or the lower portion (5) forming an angular sector (51) can be in one material different from that constituting the peripheral skirt (4).

    EXEMPLES DE REALISATIONEXAMPLES OF REALIZATION

    Les figures constituent des exemples de réalisation de capsules (1) munies d'inserts (2) et dotées de verseurs (3) selon l'invention.
    Dans ces exemples, toutes les capsules et verseurs ont été fabriqués pour le bouchage de goulots de 31,5 mm de diamètre extérieur - voit la figure 7A.    The figures are examples of embodiments of capsules (1) provided with inserts (2) and provided with pourers (3) according to the invention.
    In these examples, all the capsules and pourers were manufactured for capping 31.5 mm OD necks - see Figure 7A.

    Pour la partie métallique (10) de la capsule, on a pris une coque classique, typiquement en aluminium.For the metal part (10) of the capsule, we took a classic shell, typically in aluminium.

    En ce qui concerne les inserts (2), ils comprennent tous, comme on peut le voir sur les figures, les éléments suivants:

  • 1 - une lèvre périphérique (22) pour solidariser l'insert avec la partie métallique (10), grâce à une gorge annulaire (12), sinon il faudrait coller l'insert à la tête de la partie métallique (10),
  • 2 - une lèvre d'étanchéité (23) tournée vers l'intérieur et qui s'écrase de préférence contre le buvant (90) comme illustré sur les figures 10B à 11B, mais éventuellement contre la lèvre flexible (8F), comme illustré sur les autres figures.
  • 3 - un moyen d'assemblage temporaire de l'insert (2) et du verseur (3) servant à solidariser capsule et verseur tant que ce dernier n'est pas fixé au goulot d'une bouteille ce qui facilite considérablement l'opération de capsulage. Dans ces exemples, le moyen d'assemblage choisi est la coopération par encliquetage d'éléments flexibles dont les extrémités présentent des reliefs (20) et (40,60).
  • 4 - et un moyen de déplacement axial (21) de la pièce rigide (6) du verseur (3), lors de la fixation du verseur (3) au goulot (9) qui a lieu lors du capsulage.
    • Les inserts (2) ont été moulés en PE ou en matériau élastomère.As regards the inserts (2), they all include, as can be seen in the figures, the following elements:
  • 1 - a peripheral lip (22) for securing the insert with the metal part (10), thanks to an annular groove (12), otherwise the insert should be glued to the head of the metal part (10),
  • 2 - a sealing lip (23) facing inwards and which preferably crushes against the rim (90) as illustrated in FIGS. 10B to 11B, but possibly against the flexible lip (8F), as illustrated on FIG. the other figures.
  • 3 - a temporary assembly means of the insert (2) and the pourer (3) for securing capsule and pourer until the latter is attached to the neck of a bottle which greatly facilitates the operation of capping. In these examples, the assembly means chosen is the latching cooperation of flexible elements whose ends have reliefs (20) and (40,60).
  • 4 - and a means of axial displacement (21) of the rigid part (6) of the pourer (3), during the attachment of the pourer (3) to the neck (9) which takes place during capping.
    • The inserts (2) were molded in PE or elastomeric material.

    En ce qui concerne les verseurs (3) fabriqués, ils comprennent tous :

  • a - une jupe périphérique (4), dotée de nervures d'étanchéité (41) - sauf sur la figure 13, où des nervures d'étanchéité (512) sont portées par la partie inférieure (5), et éventuellement dotée d'un épaulement (40) pour former l'assemblage temporaire avec l'insert (voir figure 8A),
  • b - une partie inférieure rigide (5) prolongeant la jupe périphérique (4), apte à s'écarter radialement grâce notamment à la partie amincie (50) formant une charnière O. Les essais ont été réalisés avec un secteur angulaire (51) d'angle  égal à 15° -20° -25°,
  • c - un élément verseur (8) qui se présente sous la forme d'une lèvre flexible, qui, en l'absence de contraintes est en position déployée (8D), et qui sous contrainte, typiquement la pression exercée par la capsule en position fermée, est en position fléchie (8F). Cet élément verseur (8) est généralement un prolongement de l'extrémité supérieure de la jupe périphérique (4) ou, comme dans le cas du verseur de la figure 2, de la pièce rigide (6), et dans ce cas, une partie amincie (65) peut servir de charnière pour que la lèvre flexible puisse pivoter d'une position à état à l'autre.
  • d - une pièce rigide (6) dont le déplacement axial entraíne un écartement radial de la partie inférieure (5), éventuellement grâce à un moyen de coopération spécifique (7, 72,73). Cette pièce rigide peut porter un épaulement (60) pour former le moyen d'assemblage temporaire avec l'insert (2).
    • Dans le cas des verseurs des figures 1A à 2, 5A à 6B, 11A à 13, et 5B, on a fabriqué à part une pièce monobloc constituée de la jupe périphérique (4) dotée de l'élément verseur (8) et de sa partie inférieure, soit en PE, soit en élastomère. En particulier lorsque cette pièce est en élastomère, la partie inférieure (5) peut former une couronne complète, qui peut s'écarter radialement lors du mouvement axial vers le bas de la pièce rigide (6), qui a été par ailleurs fabriquée également à part par moulage de PP.
    Dans le cas des verseurs des figures 3A à 4B, 7A à 9B et 14 à 16C, le verseur est une pièce monobloc, qui a été fabriquée par moulage en PP transparent ou en PP chargé de poudre minérale, telle que du talc. La bille (630), en verre, a été introduite à force dans le verseur.
    Les figures 9A et 9B représentent des modalités relatives à la partie inférieure rigide (5).
    Comme déjà indiqué, cette partie inférieure (5) peut former une couronne, mais, dans le cas présent, elle forme une pluralité de languettes soit isolées (52), comme représenté sur la figure 9B, soit non isolées (53) car solidarisées par une jupe mince (530) comme représenté sur la figure 9A et sur la figure 8B.
    Sur les figures 9A et 9B, les flèches partant des repères 6 ou 7 symbolisent l'écartement radial des languettes (52,53) suite à la poussée directe, soit de la pièce rigide (6) seule, soit du moyen de coopération (7), selon le cas.With regard to the pourers (3) manufactured, they all include:
  • a - a peripheral skirt (4), provided with sealing ribs (41) - except in FIG. 13, where sealing ribs (512) are carried by the lower part (5), and optionally provided with a shoulder (40) to form the temporary assembly with the insert (see FIG. 8A),
  • b - a rigid lower portion (5) extending the peripheral skirt (4), adapted to deviate radially thanks in particular to the thinned portion (50) forming a hinge O. The tests were carried out with an angular sector (51) d angle  equal to 15 ° -20 ° -25 °,
  • c - a pouring element (8) which is in the form of a flexible lip which, in the absence of stresses, is in the extended position (8D), and which under stress, typically the pressure exerted by the capsule in position closed, is in the bent position (8F). This pouring element (8) is generally an extension of the upper end of the peripheral skirt (4) or, as in the case of the pourer of FIG. 2, of the rigid part (6), and in this case, a part Thinning (65) can serve as a hinge for the flexible lip to pivot from one state to another position.
  • d - a rigid part (6) whose axial displacement causes a radial spacing of the lower part (5), possibly through a specific cooperation means (7, 72,73). This rigid piece may carry a shoulder (60) to form the temporary assembly means with the insert (2).
    • In the case of the pourers of FIGS. 1A to 2, 5A to 6B, 11A to 13, and 5B, a single piece consisting of the peripheral skirt (4) provided with the pouring element (8) and its lower part, either PE or elastomer. In particular when this part is made of elastomer, the lower part (5) can form a complete ring, which can deviate radially during the downward axial movement of the rigid part (6), which has also been manufactured at the same time. by molding of PP.
    In the case of the pourers of Figures 3A to 4B, 7A to 9B and 14 to 16C, the pourer is a one-piece piece, which was manufactured by molding PP transparent or PP loaded with mineral powder, such as talc. The ball (630), made of glass, was forced into the pourer.
    FIGS. 9A and 9B show modalities relating to the rigid lower part (5).
    As already indicated, this lower part (5) can form a ring, but in this case it forms a plurality of tongues either insulated (52), as shown in FIG. 9B, or not isolated (53) since they are secured by a thin skirt (530) as shown in Figure 9A and Figure 8B.
    In FIGS. 9A and 9B, the arrows starting from marks 6 or 7 symbolize the radial spacing of the tongues (52, 53) following the direct thrust of either the rigid piece (6) alone or the cooperation means (7). ), depending on the case.

    Les tests réalisés à partir des capsules avec verseur ainsi fabriquées ont montré, à la fois sur ligne de capsulage et auprès de consommateurs, le grand intérêt de l'invention.Tests made from the pourer capsules thus manufactured showed, at the same time on the capping line and to consumers, the great interest of the invention.

    AVANTAGES DE L'INVENTIONADVANTAGES OF THE INVENTION

    D'une part, l'invention diminue considérablement les problèmes rencontrés sur ligne de capsulage dans la mesure où, sans avoir par ailleurs à modifier les lignes de capsulage, les capsules ne sont plus détériorées, avec à la fois les arrêts de production et les pertes de produits qui en sont la conséquence.
    D'autre part, l'invention divulgue des moyens qui permettent d'adapter le verseur à tout type de capsule et à tout type de diamètre.
    En outre, l'invention permet d'introduire, sans surcoût notable, une fonction complémentaire, telle que l'irremplissabilité. Dans ce cas, le verseur selon l'invention comprend des moyens qui rendent sinon impossible du moins difficile l'extraction du verseur du goulot, de manière réduire les possibilités de fraude.
    Enfin, à l'usage, la capsule et son verseur associé sont d'utilisation pratique dans la mesure où, pour le consommateur, il n'y a pas de différence sensible entre une capsule standard sans verseur ou une capsule avec verseur selon l'invention, tant en ce qui concerne la hauteur de la bouteille et son encombrement, que l'effort manuel d'ouverture, notamment pour supprimer la coopération de l'insert (2) et du verseur (3), par l'intermédiaire des moyens d'assemblage temporaire (20) et (40,60), reste dans la plage de ce qui est perçu comme habituel par le consommateur.

    On the other hand, the invention discloses means for adapting the pourer to any type of capsule and any type of diameter.
    In addition, the invention makes it possible to introduce, without significant additional cost, a complementary function, such as non-refillability. In this case, the pourer according to the invention comprises means that make it otherwise impossible at least difficult to extract the spout of the neck, so as to reduce the possibilities of fraud.
    Finally, in use, the capsule and its associated pourer are of practical use insofar as, for the consumer, there is no significant difference between a standard capsule without pourer or a capsule with pourer according to the invention, both as regards the height of the bottle and its size, that the manual opening force, in particular to remove the cooperation of the insert (2) and the pourer (3), through the means of temporary assembly (20) and (40,60), remains in the range of what is perceived as usual by the consumer.

    11. Pourer according to any one of claims 3 to 10 in which the rigid component (6) and the peripheral skirt (4) comprise male and female elements (62, 43) that co-operate and irreversibly click fit together, so as to obtain the said stable position.
    12. Pourer according to any one of claims 1 to 11, in which the closure cap (1), which is typically metallic, is provided with a plastic insert (2), that seals the closure cap (1) and includes a temporary assembly means (20) and a means of axial displacement (21) of the rigid component (6), these two means possibly being partially coincident, the temporary assembly means (20), typically being in the form of a ring, forming temporary co-operation of the insert (2) fixed to the cap (1), and the pourer (3), the axial means (21) of displacement of the insert being in direct contact on the rigid component (6H) in the said high position.
    13. Pourer according to any one of claims 1 to 12 in which the peripheral skirt (4) of the pourer includes at least one circular rib (41) making the pourer (4) leak tight with the neck (9), the width, number and flexibility of the ribs (41) being chosen so as to obtain fairly high friction with the neck to achieve the said leak tightness, but remaining sufficiently low so that the peripheral skirt (4) can be inserted in its final place in the neck (9) by pressing on the cap in the axial direction before the said downwards axial displacement of the rigid component (6) begins, when the pourer and the associated closure cap are fixed.
    14. Pourer according to claim 13 in which friction is chosen so that the force FI necessary to insert the pourer and its peripheral skirt into the neck is typically less than 10 daN, and that a force FD greater than FI and typically greater than 10 daN, and preferably between 10 and 20 daN, is necessary to achieve the said axial displacement.
    15. Pourer according to any one of claims 1 to 14 in which the peripheral skirt (4) comprises an upper rim (42) that bears on all or part of the edge (90) of the neck (9) when the peripheral skirt (4) of the pourer (3) is in place in the neck (9).
    16. Pourer according to any one of claims 1 to 15 in which the pouring element (8) is fixed either to the peripheral skirt (4) or to the rigid component (6)
    17. Pourer according to claim 16 in which the pouring element (8) comprises a flexible circular lip in the deflected state (8F) typically in contact with the edge of the neck when the neck (9) is closed by the closure cap (1), or in the deployed state (8D) when the pourer (3) has to be used, the closure cap (1) typically a screw cap, having been removed.
    18. Pourer according to any one of claims 12 to 17 in which the insert (2) comprises a sealing lip (23) facing towards the inside of the neck (9) and that will bear on the edge (90) of the neck (9) or on the pouring element (8) if the pouring element extends on the said edge, in addition to the lip (22) rigidly fixing the insert (2) to the metallic part (10) of the cap (1).
    19. Pourer according to claims 17 and 18 in which the outer diameter of the flexible circular lip in the deployed state (8D) is less than the inside diameter of the sealing lip (23), so that when the neck (9) is closed by the closure cap (1), the circular lip changes to the deflected state (8F) by being forced into contact with the sealing lip (23), itself forced into contact with the edge (90) of the neck.
    20. Pourer according to any one of claims 1 to 19 in which all or some of the leak tightness of the said leak tight attachment means between the pourer (3) and the neck (9) is achieved by at least one external rib (512) supported on the lower part (5).
    21. Pourer according to any one of claims 1 to 20 in which the peripheral skirt (4) and the rigid component (6) co-operate on tapered surfaces (44, 64) such that the said axial displacement causes a radial spacing of the peripheral skirt (4) so as to increase the attachment and / or leak tightness between the neck (9) and the pourer (3).
    22. Pourer according to any one of claims 12 to 21 in which the insert (2) may be threaded.
    23. Pourer according to any one of claims 1 to 22 in which the rigid component (6) forms a cage (63) for a ball (630) so as to form a non-refillable pourer (3I).
    24. Pourer according to any one of claims 1 to 23 formed by moulding a transparent plastic with high mechanical characteristics chosen from among PA, PET, PS and PET.
    25. Closure cap (1) temporarily fixed to a pourer (3) according to any one of claims 1 to 24, by a temporary assembly means (20) supported by the insert (2), and a temporary assembly means (40, 60) supported by the pourer (3).
