Description

L'invention est relative à un dispositif de bouchage d'un récipient muni d'un goulot, du type flacon ou pot, dispositif du genre de ceux qui comprennent d'une part un manchon cylindrique propre à entourer le goulot, ce manchon étant monté rotatif autour du goulot et, d'autre part, un couvercle en forme de plateau, articulé autour d'un axe transversal de manière à pouvoir pivoter entre une position de fermeture où le couvercle est appliqué contre l'extrémité du goulot et une position d'ouverture où le couvercle est incliné par rapport à l'axe du goulot et libère un passage pour la sortie d'un produit contenu dans le récipient.The invention relates to a device for capping a container fitted with a neck, of the flask or jar type, a device of the type of those which comprise on the one hand a cylindrical sleeve suitable for surrounding the neck, this sleeve being mounted rotatable around the neck and, on the other hand, a tray-shaped cover, articulated around a transverse axis so as to be able to pivot between a closed position where the cover is applied against the end of the neck and a position d opening where the lid is inclined relative to the axis of the neck and frees a passage for the exit of a product contained in the container.

On connaît un dispositif de ce genre dans lequel le couvercle est articulé sur une pièce intermédiaire vissée et bloquée sur un filetage du goulot, tandis que le manchon cylindrique, indépendant de ladite pièce, peut tourner autour de l'axe du goulot alors que la pièce et le couvercle restent immobiles en rotation autour de cet axe. Le mouvement de rotation du manchon permet de commander le pivotement du couvercle autour de l'axe transversal, orthogonal à l'axe du goulot.A device of this type is known in which the cover is articulated on an intermediate piece screwed and locked on a thread of the neck, while the cylindrical sleeve, independent of said piece, can rotate around the axis of the neck while the piece and the cover remain stationary in rotation about this axis. The rotation movement of the sleeve makes it possible to control the pivoting of the cover around the transverse axis, orthogonal to the axis of the neck.

Un tel dispositif de bouchage est intéressant car il réunit, en quelque sorte, les avantages du bouchon vissé et du bouchon claqué avec ouverture capsule service, sans en présenter les inconvénients.Such a closure device is interesting because it combines, in a way, the advantages of the screw cap and the slammed cap with service capsule opening, without having the disadvantages.

En effet, le bouchon vissé est en général considéré comme le moyen d'ouverture-fermeture le plus cosmétique et le plus apprécié des acheteurs.In fact, the screw cap is generally considered to be the most cosmetic opening and closing means and the most appreciated by buyers.

Le deuxième mode de fermeture, avec bouchon claqué sur lequel on vient ajouter un système de fermeture avec articulation présente des avantages de commodité et de rapidité gestuelles. Ce deuxième mode de fermeture présente par contre le désavantage d'avoir tendance à s'ouvrir tout seul dans les sacs de transport.The second closing mode, with a slam-stopper, to which a closing system with articulation has been added has advantages in terms of convenience and speed of movement. This second method of closing, on the other hand, has the disadvantage of having a tendency to open on its own in the transport bags.

Le dispositif de bouchage du genre de l'invention évite les inconvénients évoqués ci-dessus.The closure device of the kind of the invention avoids the drawbacks mentioned above.

Toutefois, la structure du dispositif de bouchage connu décrite précédemment est relativement complexe et entraîne des coûts de fabrication nettement plus élevés que ceux nécessaires pour un dispositif de bouchage ou capsule service standard.However, the structure of the known closure device described above is relatively complex and results in significantly higher manufacturing costs than those necessary for a standard closure device or service capsule.

L'invention a pour but, surtout, de fournir, un dispositif de bouchage du genre en question qui, tout en assurant une ouverture ou fermeture, par pivotement d'un couvercle, commandée par un mouvement de rotation d'un manchon, soit d'une fabrication plus simple et plus économique.The object of the invention is, above all, to provide a closure device of the kind in question which, while ensuring opening or closing, by pivoting of a cover, controlled by a rotational movement of a sleeve, either d '' simpler and more economical manufacturing.

Selon l'invention, un dispositif de bouchage du genre défini précédemment est caractérisé par le fait :

  • que des moyens d'accrochage sont prévus entre le manchon et le goulot pour permettre un mouvement de rotation relatif du manchon, sans provoquer de déplacement axial du manchon par rapport au goulot,
  • que le manchon cylindrique et le couvercle forment une capsule monobloc, le couvercle étant articulé sur le manchon à l'aide d'une charnière film,
  • et que des moyens de came avec un organe suiveur de came sont prévus entre goulot et couvercle de sorte que la rotation du manchon, qui entraîne le couvercle, s'accompagne d'un mouvement de basculement de ce couvercle, autour de l'axe transversal, de sa position de fermeture à sa position d'ouverture, ou inversement, par suite de la coopération des moyens de came du goulot (ou du couvercle) et du suiveur de came du couvercle (ou du goulot).
According to the invention, a closure device of the kind defined above is characterized by the fact:
  • that hooking means are provided between the sleeve and the neck to allow a relative rotational movement of the sleeve, without causing axial displacement of the sleeve relative to the neck,
  • that the cylindrical sleeve and the cover form a single-piece capsule, the cover being articulated on the sleeve using a film hinge,
  • and that cam means with a cam follower member are provided between neck and cover so that the rotation of the sleeve, which drives the cover, is accompanied by a tilting movement of this cover, around the transverse axis , from its closed position to its open position, or vice versa, as a result of the cooperation of the cam means of the neck (or of the cover) and of the cam follower of the cover (or of the neck).

Avantageusement, les moyens de came sont prévus sur le goulot tandis que l'organe suiveur de came est solidaire du couvercle.Advantageously, the cam means are provided on the neck while the cam follower member is integral with the cover.

De préférence, le goulot du récipient comporte un col primaire surmonté d'un col secondaire de diamètre plus réduit, et les moyens d'accrochage du manchon comprennent, côté goulot, un bourrelet circulaire prévu sur la paroi extérieure du col primaire, et, du côté manchon, un bourrelet complémentaire prévu sur la paroi interne du manchon, et propre à venir s'encliqueter derrière le bourrelet du col primaire.Preferably, the neck of the container has a primary neck surmounted by a secondary neck of smaller diameter, and the means for hooking the sleeve comprise, on the neck side, a circular bead provided on the outer wall of the primary neck, and sleeve side, a complementary bead provided on the inner wall of the sleeve, and suitable for snapping behind the bead of the primary neck.

Les moyens de came sont avantageusement constitués par une nervure hélicoïdale prévue sur le col secondaire du récipient. L'organe suiveur de came peut être constitué par une extension s'étendant à partir de la face inférieure du couvercle et comportant une gorge dans laquelle est engagée la rampe hélicoïdale du col secondaire du goulot.The cam means advantageously consist of a helical rib provided on the secondary neck of the container. The cam follower member can be constituted by an extension extending from the underside of the cover and comprising a groove in which is engaged the helical ramp of the secondary neck of the neck.

En variante, la rampe du goulot peut être remplacée par une rainure tandis que la gorge de l'extension serait remplacée par un pion en saillie propre à s'engager dans ladite rainure.As a variant, the ramp of the neck can be replaced by a groove while the groove of the extension would be replaced by a projecting pin suitable for engaging in said groove.

La rampe hélicoïdale peut comporter, à chaque extrémité, des butées limitant le mouvement de rotation. L'angle de la rampe et son profil sont choisis selon les conditions d'ouverture souhaitées. Par exemple, la rampe peut s'étendre sensiblement sur un demi-tour.The helical ramp may include, at each end, stops limiting the rotational movement. The angle of the ramp and its profile are chosen according to the desired opening conditions. For example, the ramp can extend substantially over half a turn.

De préférence, le couvercle comporte, sous sa face inférieure, une jupe d'étanchéité propre à entrer dans l'extrémité supérieure du col secondaire du goulot, et à la fermer, lorsque le couvercle est en position de fermeture.Preferably, the cover comprises, under its lower face, a sealing skirt suitable for entering the upper end of the secondary neck of the neck, and for closing it, when the cover is in the closed position.

Le couvercle peut comporter un canal radial avec un orifice interne et un orifice externe, l'ensemble étant tel qu'en position de fermeture du couvercle, l'orifice interne est bouché par le haut du col secondaire tandis que l'orifice externe est bouché par la paroi interne du manchon.The cover may include a radial channel with an internal orifice and an external orifice, the assembly being such that in the closed position of the cover, the internal orifice is blocked by the top of the secondary neck while the external orifice is blocked. through the inner wall of the sleeve.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'un exemple de réalisation décrit avec référence au dessin ci-annexé, mais qui n'est nullement limitatif.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with an exemplary embodiment described with reference to the attached drawing, but which is by no means limiting.

La figure 1, de ce dessin, est une coupe verticale axiale d'un dispositif de bouchage, selon l'invention, en position de fermeture.Figure 1 of this drawing is an axial vertical section of a closure device according to the invention, in the closed position.

La figure 2 montre, semblablement à la figure 1, le dispositif de bouchage en position d'ouverture.Figure 2 shows, similarly to Figure 1, the closure device in the open position.

La figure 3 est une vue de dessus par rapport à la figure 1.Figure 3 is a top view with respect to Figure 1.

La figure 4 est une vue de dessus du goulot, alors que le dispositif de bouchage n'est pas en place.Figure 4 is a top view of the neck, while the closure device is not in place.

La figure 5, enfin, est une vue en élévation, à plus grande échelle, de la partie haute du goulot, en l'absence du dispositif de bouchage.Figure 5, finally, is an elevational view, on a larger scale, of the upper part of the neck, in the absence of the closure device.

En se reportant au dessin, on peut voir un dispositif de bouchage B pour un récipient constitué par un flacon, par exemple en matière plastique, contenant un produit liquide ou pâteux.Referring to the drawing, one can see a closure device B for a container constituted by a bottle, for example made of plastic, containing a liquid or pasty product.

Le flacon comporte un goulot 1 cylindrique, à section circulaire. Le corps de récipient peut présenter une forme à section transversale ovale à laquelle correspond la forme d'une jupe extérieure 2 du dispositif de bouchage B, comme illustré sur la figure 3.The bottle has a cylindrical neck 1, with circular section. The container body may have a cross-sectional shape oval to which corresponds the shape of an outer skirt 2 of the closure device B, as illustrated in FIG. 3.

Le goulot 1 du flacon comporte un col primaire 3 de plus fort diamètre surmonté d'un col secondaire 4 coaxial dont l'extrémité supérieure ouverte 5 constitue l'orifice de sortie du récipient.The neck 1 of the bottle has a primary neck 3 of larger diameter surmounted by a secondary neck 4 coaxial whose open upper end 5 constitutes the outlet orifice of the container.

Le dispositif de bouchage B comprend, à l'intérieur de la jupe 2, un manchon cylindrique 6 propre à entourer le goulot 1. Des moyens d'accrochage A sont prévus entre le manchon 6 et le goulot 1 pour permettre un mouvement de rotation relatif du manchon 6 autour de l'axe X du goulot sans provoquer de déplacement axial du manchon 6 par rapport au goulot 1.The closure device B comprises, inside the skirt 2, a cylindrical sleeve 6 suitable for surrounding the neck 1. Hooking means A are provided between the sleeve 6 and the neck 1 to allow relative rotational movement of the sleeve 6 around the axis X of the neck without causing axial displacement of the sleeve 6 relative to the neck 1.

Les moyens d'accrochage A comprennent, côté goulot, un bourrelet circulaire 7 dont le plan moyen est orthogonal à l'axe X du goulot. Ce bourrelet 7 comprend une zone cylindrique 7a (figure 5) de dimension axiale réduite. Cette zone 7a se raccorde à la surface cylindrique du col primaire 3, du côté du col secondaire 4, par une surface tronconique 7b dont les génératrices sont faiblement inclinées sur l'axe X. De l'autre côté, la zone 7a se raccorde au col primaire 3 par une autre surface tronconique 7c dont les génératrices sont plus fortement inclinées par rapport à l'axe X.The attachment means A comprise, on the neck side, a circular bead 7 whose mean plane is orthogonal to the axis X of the neck. This bead 7 comprises a cylindrical zone 7 a (FIG. 5) of reduced axial dimension. This zone 7 a is connected to the cylindrical surface of the primary neck 3, on the side of the secondary neck 4, by a frustoconical surface 7 b whose generatrices are slightly inclined on the axis X. On the other side, zone 7 a is connected to the primary neck 3 by another frustoconical surface 7 c whose generatrices are more inclined relative to the axis X.

Du côté manchon 6, les moyens d'accrochage A comprennent un bourrelet 8 prévu sur la paroi intérieure du manchon et propre à venir s'encliqueter derrière le bourrelet 7 du col primaire 3. Le plan moyen du bourrelet 8 est orthogonal à l'axe du manchon 6.On the sleeve side 6, the hooking means A comprise a bead 8 provided on the inner wall of the sleeve and suitable for snapping behind the bead 7 of the primary neck 3. The mean plane of the bead 8 is orthogonal to the axis sleeve 6.

Un couvercle 9 en forme de plateau est articulé sur le manchon 6 de manière à pouvoir pivoter entre une position de fermeture (figure 1) où le couvercle 9 est appliqué contre l'extrémité 5 du goulot, et une position d'ouverture où le couvercle 9 est incliné par rapport à l'axe X du récipient et libère un passage pour la sortie du produit.A cover 9 in the form of a plate is articulated on the sleeve 6 so as to be able to pivot between a closed position (FIG. 1) where the cover 9 is applied against the end 5 of the neck, and an open position where the cover 9 is inclined relative to the axis X of the container and frees a passage for the exit of the product.

Le couvercle 9, dans l'exemple considéré, a la forme d'une plaquette sensiblement rectangulaire qui vient s'inscrire dans une ouverture correspondante prévue dans une paroi transversale 10 prévue à l'extrémité supérieure du manchon 6. Le couvercle 9 est articulé, suivant un petit côté, sur le manchon 6, à l'aide d'une charnière film 11 de sorte que la jupe 2, le manchon 6 et le couvercle 9 forment une pièce ou capsule monobloc. Le bord 12 du couvercle 9, opposé à la charnière 11, est limité par un arc de cercle propre à s'inscrire contre la surface interne du manchon 6 dans la position de fermeture du couvercle 9 comme visible sur la figure 1. Une jupe d'étanchéité 13, cylindrique, est prévue sous la face interne du couvercle 9. Cette jupe 13 est propre à entrer dans, et à fermer, l'extrémité supérieure 5 du col secondaire 4 lorsque le couvercle 9 est en position de fermeture. La jupe d'étanchéité 13 a une longueur axiale déterminée pour que cette jupe reste en contact avec l'intérieur du col 4 lorsque le couvercle 9 a pivoté au maximum vers le haut comme illustré sur la figure 2. Toutefois, dans une zone angulaire d'étendue réduite, la jupe libère un passage permettant au produit liquide du récipient 1 de s'écouler vers l'extérieur, à travers un canal radial 14 prévu dans le couvercle 9. L'orifice interne 15 du canal 14 est bouché, en position de fermeture du couvercle 9, par la paroi supérieure du col secondaire 4, tandis que l'orifice externe 16 est bouché par la paroi interne du manchon 6.The cover 9, in the example considered, has the shape of a substantially rectangular plate which fits into a corresponding opening provided in a transverse wall 10 provided at the upper end of the sleeve 6. The cover 9 is articulated, along a small side, on the sleeve 6, using a film hinge 11 so that the skirt 2, the sleeve 6 and the cover 9 form a single piece or capsule. The edge 12 of the cover 9, opposite the hinge 11, is limited by an arc of a circle suitable for fitting against the internal surface of the sleeve 6 in the closed position of the cover 9 as visible in FIG. 1. A sealing skirt 13, cylindrical, is provided under the inner face of the cover 9. This skirt 13 is suitable for entering and closing the upper end 5 of the secondary neck 4 when the cover 9 is in the closed position. The sealing skirt 13 has a determined axial length so that this skirt remains in contact with the inside of the neck 4 when the cover 9 has pivoted upwards as much as illustrated in FIG. 2. However, in an angular zone d 'reduced extent, the skirt clears a passage allowing the liquid product from the container 1 to flow towards the outside, through a radial channel 14 provided in the cover 9. The internal orifice 15 of the channel 14 is blocked, in position for closing the cover 9, by the upper wall of the secondary neck 4, while the external orifice 16 is blocked by the internal wall of the sleeve 6.

Des moyens de came C sont prévus sur le col secondaire 4 du goulot. Ces moyens de came C sont avantageusement constitués par une nervure hélicoïdale 17 constituant une rampe.Cam means C are provided on the secondary neck 4 of the neck. These cam means C are advantageously constituted by a helical rib 17 constituting a ramp.

Dans l'exemple considéré, la nervure 17 s'étend sensiblement sur 180°, comme visible sur la figure 4. Chaque extrémité de la nervure 17 comporte une butée respectivement 18, 19 pour limiter le mouvement de rotation du manchon 6.In the example considered, the rib 17 extends substantially over 180 °, as visible in FIG. 4. Each end of the rib 17 has a stop respectively 18, 19 to limit the rotational movement of the sleeve 6.

Un organe suiveur de came 20 solidaire du couvercle 9 est prévu pour coopérer avec la nervure 17. L'organe 20 est constitué par une extension, formant une sorte de plot, perpendiculaire au plan moyen du couvercle 9 et située au droit du canal 14 lequel a son axe situé dans le plan médiateur du couvercle 9, à égale distance des grands côtés de ce couvercle.A cam follower member 20 secured to the cover 9 is provided to cooperate with the rib 17. The member 20 is constituted by an extension, forming a sort of stud, perpendicular to the mean plane of the cover 9 and located in line with the channel 14 which has its axis located in the mediating plane of the cover 9, equidistant from the long sides of this cover.

L'extension 20 comporte, vers son extrémité inférieure, sur sa paroi adjacente au col 4, une gorge 21 dans laquelle est engagée la rampe hélicoïdale 17.The extension 20 comprises, towards its lower end, on its wall adjacent to the neck 4, a groove 21 in which the helical ramp 17 is engaged.

Ceci étant, le fonctionnement du dispositif de bouchage est le suivant.However, the operation of the closure device is as follows.

La position de fermeture, illustrée sur la figure 1, est obtenue en plaçant le manchon 6 dans la position angulaire où la gorge 21 coopère avec l'extrémité inférieure de la rampe 17.The closed position, illustrated in FIG. 1, is obtained by placing the sleeve 6 in the angular position where the groove 21 cooperates with the lower end of the ramp 17.

Pour obtenir l'ouverture du récipient, on fait tourner le manchon 6 relativement au goulot 1, dans le sens approprié pour provoquer la montée de la gorge 21 le long de la nervure 17.To obtain the opening of the container, the sleeve 6 is turned relative to the neck 1, in the appropriate direction to cause the groove 21 to rise along the rib 17.

En fin de course, le couvercle 9 occupe la position de la figure 2 pour laquelle l'orifice externe 16 du canal 14 se trouve au-delà du bord du manchon 6 et l'orifice interne 15 de ce canal 14 communique avec l'espace intérieur du col 4. En retournant le flacon 1, on peut provoquer l'écoulement du produit vers l'extérieur.At the end of the race, the cover 9 occupies the position of FIG. 2 for which the external orifice 16 of the channel 14 is located beyond the edge of the sleeve 6 and the internal orifice 15 of this channel 14 communicates with the space inside the neck 4. By inverting the bottle 1, the product can flow outwards.

L'angle d'inclinaison de la nervure ou rampe 17 par rapport à l'axe X et le profil de cette nervure peuvent être choisis et modifiés à volonté, par exemple pour que l'ouverture du couvercle 9 ne se produise que dans le dernier tiers du mouvement de rotation du manchon 6.The angle of inclination of the rib or ramp 17 relative to the axis X and the profile of this rib can be chosen and modified at will, for example so that the opening of the cover 9 occurs only in the last third of the rotation movement of the sleeve 6.

Dans le mode de réalisation décrit, l'ouverture est obtenue par une rotation de 180° du manchon 6 par rapport au goulot 1. Cette réalisation peut être modifiée de manière qu'une rotation de 90° du manchon 6 soit suffisante pour obtenir l'ouverture totale.In the embodiment described, the opening is obtained by a 180 ° rotation of the sleeve 6 relative to the neck 1. This embodiment can be modified so that a 90 ° rotation of the sleeve 6 is sufficient to obtain the total opening.

Le dispositif de bouchage de l'invention est simple et économique à fabriquer puisque le couvercle 9, le manchon 6, et la jupe 2 lorsqu'elle existe, peuvent être moulés d'une seule pièce.The closure device of the invention is simple and economical to manufacture since the cover 9, the sleeve 6, and the skirt 2 when it exists, can be molded in one piece.
