Description

Capsule de bouchage en matière plastique, à jupe d'étanchéité. Plastic cap, with sealing skirt.
La présente invention se rapporte à une capsule de bouchage en matière plastique pour un col de récipient, comprenant une paroi d'extrémité sur laquelle font saillie dans le même sens une jupe extérieure comportant intérieurement des moyens pour la fixation de la capsule sur le col du récipient et une jupe intérieure d'étanchéité coopérant par serrage avec la surface intérieure du col pour obturer ce dernier.The present invention relates to a plastic closure cap for a container neck, comprising an end wall on which protrude in the same direction an outer skirt having internally means for fixing the capsule on the neck of the container. container and an inner sealing skirt cooperating by tightening with the inner surface of the neck to seal the latter.
Les capsules de ce type présentent des jupes d'étanchéité, soit cylindriques, soit de formes plus coinplexes (par exemple avec un premier tronçon tronconique divergeant suivi d'un second tronçon tronconique convergeant, avec un tronçon cylindrique suivi d'un rebord extérieur repliable en direction de la paroi d'extrémité de la capsule, avec des jupes cylindriques comportant un rebord ou bourrelet extérieur à leur extrémité libre, avec un profil en olive ou analogue, etc.). Ces jupes de formes plus complexes compliquent le moulage des capsules. Toutes ces formes complexes des jupes d'étanchéité visent à améliorer l'étanchéité, notamment pour des liquides sous pression tels que des boissons carbonatées, étanchéité établie de préférence au voisinage de l'extrémité libre de la jupe, donc dans une position en retrait par rapport au bord libre du col. Sur les capsules à vis comportant de telles jupes, il est par ailleurs désirable de réduire le couple qui doit être exercé par l'utilisateur pour dévisser la capsule.Capsules of this type have sealing skirts, either cylindrical or of more coinplexed shapes (for example with a first diverging frustoconical section followed by a second converging frustoconical section, with a cylindrical section followed by a foldable outer rim in direction of the end wall of the capsule, with cylindrical skirts having an outer rim or bead at their free end, with an olive or similar profile, etc.). These skirts of more complex shapes complicate the molding of the capsules. All these complex forms of sealing skirts aim to improve sealing, especially for pressurized liquids such as carbonated drinks, sealing preferably established in the vicinity of the free end of the skirt, therefore in a position set back by compared to the free edge of the neck. On screw capsules comprising such skirts, it is moreover desirable to reduce the torque which must be exerted by the user to unscrew the capsule.
Or, les jupes d'étanchéité connues ne répondent que de façon imparfaite à l'ensemble des exigences concernant la facilité de moulage, la bonne étanchéité et le couple de dévissage réduit. La présente invention vise une capsule de bouchage comportant une jupe d'étanchéité conformée de manière à répondre de façon optimale à ces différentes exigences.However, the known sealing skirts only meet imperfectly all the requirements concerning the ease of molding, good sealing and reduced unscrewing torque. The present invention relates to a closure cap comprising a sealing skirt shaped so as to optimally meet these different requirements.
Sur la capsule en matière plastique, objet de l'invention, pour le bouchage d'un col de récipient, comprenant une paroi d'extrémité sur laquelle font saillie dans le même sens une jupe extérieure comportant intérieurement des moyens pour la fixation de la capsule sur le col du récipient et une jupe intérieure d'étanchéité coopérant par serrage avec la surface intérieure du col pour obturer ce dernier, la jupe intérieure diverge au moins extérieurement en tronc de cône depuis sa base en direction de son extrémité libre, au moins le diamètre extérieur de la jupe au voisinage de son extrémité libre étant supérieur au diamètre intérieur nominal du col de récipient, la conicité de la jupe étant telle qu'elle ne gêne pas le démoulage axial.On the plastic capsule, object of the invention, for plugging a container neck, comprising an end wall on which protrude in the same direction an outer skirt internally comprising means for fixing the capsule on the container neck and an inner sealing skirt cooperating by tightening with the inside surface of the neck to close off the latter, the inside skirt diverges at least externally in a truncated cone from its base towards its free end, at least the outside diameter of the skirt in the vicinity of its free end being greater than the nominal inside diameter of the container neck, the taper of the skirt being such that it does not interfere with the axial release.
Cette conformation de la jupe d'étanchéité permet de concentrer l'effet de serrage de ladite jupe contre la surface intérieure du col du récipient essentiellement au voisinage de l'extrémité libre de la jupe, ce qui assure à la fois une bonne étanchéité, un couple de dévissage réduit et un positionnement optimal du contact jupe-col dans la mesure où la pression de gaz éventuelle à l'intérieur du récipient renforce le contact de la jupe avec le col de récipient. Malgré cela, la conicité de la jupe est suffisamment faible pour autoriser un simple démoulage axial de la jupe.This conformation of the sealing skirt makes it possible to concentrate the tightening effect of said skirt against the interior surface of the neck of the container essentially in the vicinity of the free end of the skirt, which ensures both good sealing, a reduced unscrewing torque and optimal positioning of the skirt-neck contact insofar as the possible gas pressure inside the container reinforces the contact of the skirt with the container neck. Despite this, the taper of the skirt is low enough to allow a simple axial demolding of the skirt.
De préférence, la surface extérieure tronconique de la jupe peut présenter une pente comprise entre environ 1° et 5°, de préférence une pente d'environ 2°. Pour améliorer l'engagement de la jupe dans le col de récipient, la jupe peut avantageusement présenter, à son extrémité libre, un chanfrein extérieur dont le diamètre intérieur est inférieur au diamètre intérieur nominal du col de récipient.Preferably, the frustoconical outer surface of the skirt may have a slope of between approximately 1 ° and 5 °, preferably a slope of approximately 2 °. To improve the engagement of the skirt in the container neck, the skirt may advantageously have, at its free end, an external chamfer whose internal diameter is less than the nominal internal diameter of the container neck.
La surface intérieure de la jupe peut être cylindrique ou peut également diverger en tronc de cône, auquel cas la conicité de la surface intérieure est égale ou de préférence inférieure à celle de la surface extérieure de la jupe.The inner surface of the skirt may be cylindrical or may also diverge into a frustum, in which case the taper of the interior surface is equal to or preferably less than that of the exterior surface of the skirt.
Selon la conformation du buvant du col de récipient, la jupe peut avantageusement présenter une longueur comprise entre environ 3 et 6 mm, de préférence une longueur d'environ 4 mm. La capsule conforme à l'invention peut être réalisée par moulage à partir de toutes les matières plastiques utilisées communément pour les capsules à jupe d'étanchéité, par exemple le polyéthylène, le polypropylène ou des matières analogues. En se référant aux dessins schématiques annexés, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif d'une capsule de bouchage conforme à l'invention; sur les dessins :Depending on the shape of the rim of the container neck, the skirt may advantageously have a length of between approximately 3 and 6 mm, preferably a length of approximately 4 mm. The capsule according to the invention can be produced by molding from all the plastics commonly used for capsules with a sealing skirt, for example polyethylene, polypropylene or the like. Referring to the appended schematic drawings, there will be described below in more detail an illustrative and nonlimiting embodiment of a closure cap according to the invention; on the drawings:
- la figure 1 est une coupe axiale d'une capsule conforme à l'invention; - la figure 2 représente, à plus grande échelle, le détail II de la figure 1 montrant le profil de la jupe d'étanchéité.- Figure 1 is an axial section of a capsule according to the invention; - Figure 2 shows, on a larger scale, detail II of Figure 1 showing the profile of the sealing skirt.
La capsule de bouchage 1 telle qu'illustrée par la figure 1, comprend un corps de capsule 2 et une bande d'inviolabilité 3 moulée d'une seule pièce avec le corps 2. Dans la mesure où la bande d'inviolabilité 3 n'entre pas dans le cadre de la présente invention, il n'y a pas lieu de la décrire plus en détail.The closure cap 1 as illustrated in FIG. 1 comprises a capsule body 2 and a tamper-evident band 3 molded in one piece with the body 2. Insofar as the tamper-evident band 3 does not is not within the scope of the present invention, there is no need to describe it in more detail.
Le corps de capsule 2 comprend essentiellement une paroi d'extrémité 4, une jupe extérieure 5 qui fait saillie sur la paroi 4, sur le bord extérieur de cette dernière, et présente intérieurement un filet 6 et extérieurement un moletage 7, et une jupe d'étanchéité intérieure 8 qui fait saillie sur la paroi 4 dans le même sens que la jupe 5, dans une position concentrique à cette dernière. La jupe d'étanchéité 8 est destinée à coopérer, lors du vissage de la capsule 1 sur un col de bouteille 9 représenté schématiquement en dessous de la capsule 1 sur la figure 1, par serrage avec la surface intérieure du col 9, cette surface présentant un diamètre intérieur nominal Di9.The capsule body 2 essentially comprises an end wall 4, an outer skirt 5 which projects from the wall 4, on the outer edge of the latter, and has internally a thread 6 and externally a knurling 7, and a skirt d 'inner seal 8 which projects from the wall 4 in the same direction as the skirt 5, in a position concentric with the latter. The sealing skirt 8 is intended to cooperate, when the cap 1 is screwed onto a bottle neck 9 shown diagrammatically below the cap 1 in FIG. 1, by tightening with the inside surface of the neck 9, this surface having a nominal inside diameter Di9.
Comme le montre plus clairement la figure 2, la jupe d'étanchéité 8 diverge en tronc de cône, tant intérieurement qu'extérieurement, de sa base (paroi d'extrémité 4) en direction de son extrémité libre. La surface extérieure de la jupe 8 présente une pente et la surface intérieure une pente β. Le diamètre extérieur maximal De8 max au voisinage de l'extrémité libre de la jupe 8 est supérieur au diamètre intérieur Di9 du col de bouteille 9. La jupe 8 présente, à son extrémité libre, un chanfrein extérieur 10 dont le diamètre intérieur DilO est inférieur au diamètre intérieur nominal Di9 du col de bouteille 9. A titre d'exemple, sur une capsule telle que représentée, destinée à boucher un col de bouteille 9 présentant un diamètre intérieur nominal Di9 de l'ordre de 25 mm, le diamètre extérieur minimal De8 min de la jupe 8 ayant une longueur L8 de l'ordre de 4 mm peut être de l'ordre de 25,48 mm et le diamètre extérieur maximal De8 max de la jupe 8 de l'ordre deAs shown more clearly in Figure 2, the sealing skirt 8 diverges in a truncated cone, both internally and externally, from its base (end wall 4) towards its free end. The outer surface of the skirt 8 has a slope and the inner surface a slope β. The maximum external diameter De8 max in the vicinity of the free end of the skirt 8 is greater than the internal diameter Di9 of the bottle neck 9. The skirt 8 has, at its free end, an external chamfer 10 whose internal diameter DilO is less at the nominal inside diameter Di9 of the bottle neck 9. By way of example, on a cap as shown, intended to cap a bottle neck 9 having a nominal internal diameter Di9 of the order of 25 mm, the minimum external diameter De8 min of the skirt 8 having a length L8 of the order of 4 mm can be of the order of 25.48 mm and the maximum outside diameter De8 max of the skirt 8 of the order of
25,72 mm, l'épaisseur radiale de la jupe 8 de l'ordre de 0,8 mm et le diamètre intérieur DilO du chanfrein 10 de l'ordre de 24,50 mm, les angles α et β étant respectivement de 2°.25.72 mm, the radial thickness of the skirt 8 of the order of 0.8 mm and the internal diameter DilO of the chamfer 10 of the order of 24.50 mm, the angles α and β being respectively 2 ° .
Il va de soi que le mode de réalisation illustré et décrit ci-dessus n'a été donné qu'à titre indicatif et non limitatif et de nombreuses modifications et variantes sont possibles dans le cadre de l'invention.It goes without saying that the embodiment illustrated and described above has been given for information only and is not limitative and numerous modifications and variants are possible within the scope of the invention.
Ainsi, les deux angles de pente α et β de la surface extérieure et de la surface intérieure de la jupe 8, au lieu d'être égaux pourraient être différents, l'angle β étant alors inférieur à l'angle α et pouvant même être égal à 0°, en fonction par exemple de la matière constitutive de la capsule, de la longueur de la jupe 8, de l'épaisseur de la jupe 8, du diamètre du col de bouteille, etc. Thus, the two angles of slope α and β of the outer surface and of the inner surface of the skirt 8, instead of being equal, could be different, the angle β then being less than the angle α and may even be equal to 0 °, depending for example on the material of the capsule, the length of the skirt 8, the thickness of the skirt 8, the diameter of the bottle neck, etc.
