Description
La présente invention concerne un système de fermeture d'un flacon tel qu'une bouteille et un procédé de pose d'un bouchon sur un col de flacon formant un tel système.The present invention relates to a closure system of a bottle such as a bottle and a method of laying a cap on a neck of the bottle forming such a system.
Parmi les techniques de fermeture d'un flacon comportant un col avec un bouchon en matière synthétique, on connait un système dans lequel le bouchon comporte une base et un capuchon monté de manière amovible ou articulée sur la base. On peut ainsi ouvrir et fermer le flacon à plusieurs reprises. Dans un tel système, le col comporte une collerette, tandis que la base comporte une jupe externe de forme sensiblement tubulaire entourant le col et comportant une saillie annulaire formant les moyens d'accrochage. Après insertion à force de la base sur le col, la saillie annulaire franchit la collerette et coopère avec elle pour retenir la base sur le col.Among the closure techniques of a bottle having a neck with a plastic cap, there is known a system in which the cap has a base and a cap removably mounted or hinged to the base. It is thus possible to open and close the bottle several times. In such a system, the collar comprises a flange, while the base comprises an outer skirt of substantially tubular shape surrounding the neck and having an annular projection forming the attachment means. After insertion of the base on the neck, the annular projection passes the collar and cooperates with it to retain the base on the neck.
Dans un procédé de pose d'un tel bouchon, par exemple sur une chaîne d'embouteillage, après le remplissage du flacon, on a une étape de dépose du bouchon sur le col dans laquelle le flacon est en déplacement linéaire et tangente par le col une rampe présentant le bouchon avec la jupe externe inclinée et emporte le bouchon ainsi inséré sur le col. La rampe contient une file de bouchon qui descendent par gravité jusqu'à une butée escamotable. Après que le bouchon est déposé sur le col, la base repose sur le buvant du col par la saillie annulaire tandis que la jupe d'étanchéité effectue un centrage de la base. Suit une étape de transport dans laquelle le flacon est déplacé avec le bouchon déposé sur le col et centré par la jupe d'étanchéité, puis une étape de fixation dans laquelle la liaison entre les moyens d'accrochage et la collerette est établie, par emmanchement forcé qui impose à la saillie annulaire de franchir la collerette. Le document
On constate que ce procédé impose d'avoir des jupes d'étanchéité dont la distance entre le bord inférieur et la saillie annulaire est suffisamment longue. En effet, l'étape de transport peut être assortie de chaos qui risquent de faire tomber le bouchon avant l'étape de fixation. Il est pourtant intéressant de faire des jupes d'étanchéité courtes afin d'alléger les bouchons et de se prémunir des rayures ou éclats, par exemple lors de l'insertion de cannes de remplissage de la bouteille, de telles jupes d'étanchéité étant décrites dans la demande de brevet français N°
L'invention vise un système de fermeture d'un flacon dont la fixation ne comporte pas de risques, même si la jupe d'étanchéité est courte. Elle vise également à fournir un procédé de fermeture d'un flacon adapté à ce système.The invention relates to a closure system of a bottle whose fixing does not involve risks, even if the sealing skirt is short. It also aims to provide a method of closing a bottle adapted to this system.
Avec ces objectifs en vue, l'invention a pour objet un système de fermeture d'un flacon, le système comportant un col délimitant une ouverture du flacon et un bouchon apte à fermer l'ouverture de manière amovible, le bouchon comportant une jupe externe de forme sensiblement tubulaire, le système comportant des moyens de fixation du bouchon sur le col, comprenant une collerette de fixation s'étendant sur la périphérie du col et des moyens d'accrochage à l'intérieur de la jupe externe, le bouchon intégrant une jupe d'étanchéité, caractérisé en ce que la jupe externe comporte en outre une lèvre intérieure faisant saillie vers l'intérieur de la jupe externe, le diamètre intérieur de la lèvre étant inférieur au diamètre extérieur de la collerette de fixation, la lèvre étant disposée et configurée de telle sorte qu'elle est apte à franchir la collerette de fixation lorsque le plan de la lèvre est placé de manière oblique par rapport au plan de la collerette de fixation et à retenir le bouchon lorsque le plan de la lèvre est placé parallèlement au plan de la collerette de fixation.With these objectives in view, the invention relates to a closure system of a bottle, the system comprising a neck defining an opening of the bottle and a cap adapted to close the opening removably, the cap having an outer skirt of substantially tubular shape, the system comprising means for fixing the cap on the neck, comprising a fastening flange extending on the periphery of the neck and fastening means inside the outer skirt, the plug incorporating a sealing skirt, characterized in that the outer skirt further comprises an inner lip projecting inwardly of the outer skirt, the inner diameter of the lip being smaller than the outer diameter of the attachment flange, the lip being disposed and configured so that it is able to cross the fastening flange when the plane of the lip is placed obliquely with respect to the plane of the fastening collar and to retain the plug when the plane of the lip is placed parallel to the plane of the fixing collar.
La lèvre, bien qu'étant apte à retenir le bouchon sur la collerette de fixation, franchit facilement celle-ci lorsque la jupe externe est inclinée car la lèvre n'entre en contact avec la collerette de fixation que sur deux points diamétralement opposés. La jupe externe est apte à subir une petite déformation élastique, qui peut être décrite comme une ovalisation. Après ce franchissement, lorsque le bouchon est libéré de la rampe, il se place par gravité avec les moyens d'accrochage en appui sur la collerette de fixation, celle-ci se plaçant entre les moyens d'accrochage et la lèvre. Le bouchon est alors retenu sur le col, même en cas de secousses qui seraient données au flacon. Cette garantie de maintien permet de réaliser des jupes d'étanchéité courtes.The lip, while being able to hold the cap on the fastening flange, easily passes it when the outer skirt is inclined because the lip comes into contact with the fastening flange at two diametrically opposite points. The outer skirt is able to undergo a small elastic deformation, which can be described as ovalization. After this crossing, when the cap is released from the ramp, it is placed by gravity with the hooking means bearing on the mounting flange, the latter being placed between the attachment means and the lip. The cap is then retained on the neck, even in case of shaking that would be given to the bottle. This maintenance guarantee makes it possible to produce short sealing skirts.
Selon un perfectionnement, le diamètre intérieur de la lèvre est inférieur de 0 à 0,9 mm au diamètre extérieur de la collerette de fixation, de préférence de 0,4 à 0,6 mm. Les meilleurs résultats ont été constatés autour de ces valeurs. Une dimension plus importante de l'écart rend plus difficile l'insertion du bouchon. Un écart trop faible hypothèque le maintien du bouchon en cas de secousses.According to an improvement, the inside diameter of the lip is 0 to 0.9 mm less than the outer diameter of the attachment flange, preferably 0.4 to 0.6 mm. The best results were observed around these values. A larger dimension of the gap makes it more difficult to insert the plug. A gap too low mortgages the maintenance of the plug in case of shaking.
Selon une autre caractéristique, la section de la lèvre présente une pointe d'un rayon inférieur à 0,3 mm. Un faible rayon et une faible largeur facilitent le franchissement de la collerette de fixation.According to another feature, the section of the lip has a tip with a radius less than 0.3 mm. A small radius and a small width facilitate the crossing of the fastening flange.
De manière préférentielle, le bouchon est en matière thermoplastique.Preferably, the plug is made of thermoplastic material.
Selon un perfectionnement, le bouchon comporte un capuchon amovible ou articulé. Le capuchon est par exemple vissé sur une base pour être amovible, ou monté pivotant sur le bord de la base.According to an improvement, the cap comprises a removable or articulated cap. The cap is for example screwed on a base to be removable, or pivotally mounted on the edge of the base.
L'invention a aussi pour objet un procédé de pose d'un bouchon sur un col de flacon formant un système selon l'une des revendications précédentes, le col délimitant une ouverture du flacon, le bouchon fermant l'ouverture de manière amovible, le bouchon comportant une jupe externe de forme sensiblement tubulaire, le système comportant des moyens de fixation du bouchon sur le col, comprenant une collerette de fixation s'étendant sur la périphérie du col et des moyens d'accrochage à l'intérieur de la jupe externe, le procédé comportant une étape de dépose du bouchon sur le col dans laquelle le flacon est en déplacement linéaire et tangente par le col une rampe présentant le bouchon avec la jupe externe inclinée et emporte le bouchon ainsi inséré sur le col, une étape de transport dans laquelle le flacon est déplacé avec le bouchon déposé sur le col et centré par la jupe d'étanchéité , et une étape de fixation dans laquelle la liaison entre les moyens d'accrochage et la collerette de fixation est établie, le procédé étant caractérisé en ce que la jupe externe comporte en outre une lèvre intérieure faisant saillie vers l'intérieur de la jupe externe, le diamètre intérieur de la lèvre étant inférieur au diamètre extérieur de la collerette de fixation, la lèvre franchissant la collerette de fixation lors de l'étape de dépose, le plan de la lèvre étant placé de manière oblique par rapport au plan de la collerette de fixation au début de l'étape de dépose par l'inclinaison de la rampe.The subject of the invention is also a process for laying a stopper on a neck of a bottle forming a system according to one of the claims previous, the neck defining an opening of the bottle, the plug closing the opening removably, the cap having an outer skirt of substantially tubular shape, the system comprising means for fixing the cap on the neck, comprising a mounting flange s extending on the periphery of the neck and fastening means inside the outer skirt, the method comprising a step of removing the stopper on the neck in which the bottle is in linear displacement and tangent by the neck a ramp having the plug with the inclined outer skirt and carries the plug thus inserted on the neck, a transport step in which the bottle is moved with the cap deposited on the neck and centered by the sealing skirt, and a fixing step in which the connection between the fastening means and the fastening flange is established, the method being characterized in that the outer skirt further comprises a lens inner projection projecting inwardly of the outer skirt, the inside diameter of the lip being less than the outside diameter of the fixing flange, the lip crossing the fixing flange during the removal step, the plane of the lip being placed obliquely with respect to the plane of the fastening flange at the beginning of the depositing step by the inclination of the ramp.
De manière particulière, les moyens d'accrochage comportent une saillie annulaire à l'intérieur de la jupe externe franchisant à force la collerette de fixation lors l'étape de fixation et coopérant avec elle pour maintenir le bouchon sur le col.In particular, the attachment means comprise an annular projection inside the outer skirt forcing the fastening flange during the fixing step and cooperating with it to hold the cap on the neck.
