Description

BOUCHON A MOYEN VERSEUR CAP WITH MEDIUM SIZE
L'invention est relative à un bouchon à moyen verseur. Un tel bouchon est typiquement destiné à des récipients (tels que des bouteilles) de conditionnement d'un contenu liquide ou pâteux notamment alimentaire tel que de l'huile, de la sauce, du vinaigre, un produit laitier, ou autres.The invention relates to a medium-pour plug. Such a cap is typically intended for containers (such as bottles) for packaging a liquid or pasty food including such as oil, sauce, vinegar, a dairy product, or the like.
EP-A-O 472 655 décrit un bouchon comprenant un corps verseur incluant un opercule et une capsule incluant une charnière. Pour le fabriquer, on réalise le corps verseur par moulage par injection de matière plastique souple, le bord du corps verseur ayant une forme de tenon, puis on réalise la capsule en position d'ouverture, par surmoulage localisé au tenon, de matière plastique dure, le bord de la capsule ayant une partie de liaison avec le tenon. Le corps verseur fait partie d'une embase ayant une jupe de fixation au col du récipient et une ceinture placée à l'extérieur où se trouve le tenon. La capsule inclut une jupe interne d'étanchéité et une jupe externe ayant sur son bord la charnière, à proximité de la partie de liaison. La charnière, qui assure une position de fermeture et, à environ 135°, une position d'ouverture, est située sensiblement dans le plan de joint extérieur du corps verseur et de la capsule et elle est écartée axialement du bord de la jupe d'étanchéité. Le bouchon peut comporter, à l'opposé de la charnière, des moyens d'inviolabilité arrachables. Ce type de bouchon a pour inconvénients que sa réalisation est complexe, que la course d'ouverture est bien inférieure à 180°, que la quantité de matière utilisée est importante, l'embase comportant, outre la jupe de fixation, la collerette divergente, que l'encombrement tant axialement que radialement est important.EP-A-0 472 655 discloses a cap comprising a pouring body including a cap and a capsule including a hinge. In order to manufacture it, the pouring body is made by injection molding of flexible plastic material, the edge of the pouring body having a tenon shape, then the capsule is made in the open position, by localized overmolding with the pin, of hard plastic material. , the edge of the capsule having a connection portion with the tenon. The pouring body is part of a base having a skirt for fixing the neck of the container and a belt placed on the outside where the post is located. The capsule includes an internal sealing skirt and an outer skirt having on its edge the hinge, close to the connecting portion. The hinge, which provides a closed position and, at about 135 °, an open position, is located substantially in the outer joint plane of the pouring body and the capsule and is spaced axially from the edge of the skirt of seal. The cap may comprise, opposite the hinge, tearproof tamperproof means. This type of plug has the disadvantages that its implementation is complex, that the opening stroke is much less than 180 °, the amount of material used is important, the base comprising, in addition to the fixing skirt, the diverging collar, that the space both axially and radially is important.
EP-A-O 685 406 décrit un bouchon ayant, fabriqués séparément, un moyen verseur incluant des moyens de régularisation de débit et une capsule incluant une charnière, celui-ci étant d'abord inséré dans celle-là, puis l'ensemble étant placé sur le col du récipient. La capsule comprend une jupe extérieure de fixation au col du récipient, un capot monté pivotant, et sur la jupe extérieure une bande d'inviolabilité arrachable et une charnière formée d'une épaisseur réduite, situées sensiblement dans un même plan transversal. En position d'ouverture, le capot est à 90° par rapport à la position de fermeture. Pour maintenir la position d'ouverture, la jupe d'étanchéité doit être suffisamment longue pour être en appui sur le bord du moyen verseur. Ce bouchon a pour inconvénients que la course d'ouverture est limitée à 90°, que la bande d'inviolabilité arrachée constitue un déchet gênant et crée un espace vide inesthétique, qu'il n'est pas prévu d'opercule sur le moyen verseur, qu'il n'est pas possible de réaliser une capsule transparente permettant à l'utilisateur de voir à travers la paroi sommitale de la capsule.EP-A-0 685 406 discloses a plug having, separately manufactured, a pouring means including flow control means and a capsule including a hinge, the latter being first inserted into that one, and then the assembly being placed on the neck of the container. The capsule comprises an outer skirt for attachment to the neck of the container, a pivotally mounted cover, and on the outer skirt a tear-proof strip and a hinge formed of a reduced thickness, located substantially in the same transverse plane. In the open position, the hood is at 90 ° to the closed position. To maintain the open position, the sealing skirt must be long enough to bear on the edge of the pouring means. This plug has the disadvantage that the opening stroke is limited to 90 °, that the torn tamper band is an annoying waste and creates an unsightly empty space, it is not expected to operculum on the pourer , that it is not possible to make a transparent capsule allowing the user to see through the top wall of the capsule.
L'invention propose un bouchon à moyen verseur qui soit de réalisation simple, de course d'ouverture pouvant atteindre de l'ordre de 180°, ne nécessitant qu'une quantité de matière limitée, d'encombrement réduit, ne générant aucun déchet lors de l'ouverture, esthétique, et dont le capot peut être transparent.The invention proposes a medium-pouring cap that is simple in its construction, with an opening stroke of up to about 180 °, requiring only a limited quantity of material, of reduced size, generating no waste during opening, aesthetic, and whose hood can be transparent.

Selon une réalisation, le bouchon comporte également des moyens extérieurs assurant l'inviolabilité avant une première ouverture, sous la forme de ponts frangibles ou équivalent reliant le bord libre de la jupe du capot au bord en regard et adjacent de la bague.According to one embodiment, the cap also comprises external means ensuring the inviolability before a first opening, in the form of bridges frangibles or equivalent connecting the free edge of the hood skirt to the edge opposite and adjacent to the ring.
Selon une réalisation, le bouchon comporte également un opercule arrachable qui constitue des moyens intérieurs assurant l'inviolabilité avant une première ouverture et des moyens de protection du contenu du récipient. Selon une réalisation, le bouchon comporte également des moyens régulateurs de l'écoulement du contenu du récipient.According to one embodiment, the stopper also comprises a tear-off cap which constitutes internal means ensuring the inviolability before a first opening and means for protecting the contents of the container. In one embodiment, the cap also comprises means for regulating the flow of the contents of the container.
Selon un autre aspect, l'invention le procédé de fabrication d'un bouchon tel qu'il vient d'être décrit. Selon ce procédé, on moule par injection séparément les deux pièces constitutives du bouchon, la seconde pièce pouvant être moulée fermée, puis on assemble rigidement entre elles deux pièces grâce aux premiers et seconds moyens de fixation, avec nécessité d'orienter les deux pièces l'une par rapport à l'autre.In another aspect, the invention the method of manufacturing a plug as just described. According to this process, the two component parts of the plug are injection-molded separately, the second part being able to be molded closed, and then two pieces are rigidly joined together by means of the first and second fastening means, with the need of orienting the two parts together. one with respect to the other.

Le bouchon à moyen verseur, en matière plastique et d'axe général de révolution Z, est typiquement destiné à des récipients (tels que des bouteilles) de conditionnement d'un contenu liquide ou pâteux notamment alimentaire tel que de l'huile, de la sauce, du vinaigre, un produit laitier, ou autres.The medium-pouring cap, made of plastic and having a general axis of revolution Z, is typically intended for containers (such as bottles) for packaging a liquid or pasty food-related content such as oil, sauce, vinegar, a dairy product, or others.
Dans la réalisation représentée, le bouchon comprend une première pièce 1 et une seconde pièce 2, associées rigidement l'une à l'autre. La première pièce 1 - par exemple en polyéthylène - forme une embase 3 périphérique et un moyen verseur 4. Elle inclut également des premiers moyens 5 périphériques de fixation pour la seconde pièce 2.In the embodiment shown, the cap comprises a first part 1 and a second part 2, rigidly associated with each other. The first piece 1 - for example polyethylene - forms a peripheral base 3 and a pouring means 4. It also includes first peripheral fixing means 5 for the second part 2.
La seconde pièce 2 - par exemple en polypropylène transparent - forme un capot 6, des moyens 7 de pivotement du capot 6 et des seconds moyens 8 périphériques de fixation complémentaires des premiers moyens 5 de fixation.The second piece 2 - for example made of transparent polypropylene - forms a cover 6, means 7 for pivoting the cover 6 and second peripheral attachment means 8 complementary to the first fixing means 5.
Le bouchon est décrit en supposant l'axe Z vertical, l'embase 3 vers le bas et le capot 6 vers le haut. C'est par rapport à cette position que doivent être compris les mots « haut », « bas », « au-dessus », « au-dessous », « sommet »... Le mot « axial » se réfère à l'axe Z, tandis que le mot « transversal » vise ce qui est perpendiculaire à l'axe Z. Selon le contexte le mot « interne » (ou « intérieur ») vise soit ce qui se trouve situé dans le bouchon stricto sensu soit ce qui est tourné vers ou proche de l'axe Z, tandis que le mot « externe » (ou « extérieur ») vise l'inverse. Sauf indication contraire, le bouchon est décrit en position de fermeture avant sa première utilisation.The cap is described assuming the vertical Z axis, the base 3 down and the hood 6 upwards. It is in relation to this position that must be understood the words "high", "low", "above", "below", "top" ... The word "axial" refers to the Z axis, while the word "transversal" refers to what is perpendicular to the Z axis. Depending on the context, the word "internal" (or "inside") refers to what is located in the cap stricto sensu or what is turned towards or close to the Z axis, while the word "external" (or "outside") is the opposite. Unless otherwise specified, the plug is described in the closed position prior to first use.
L'embase 3 comporte une jupe extérieure 9 de forme générale cylindrique, dirigée vers le bas agencée pour, et destinée à, être fixée sur le col du récipient, grâce à des moyens de fixation appropriés complémentaires l'un de l'autre, tels qu'une collerette en saillie ou un filetage, prévu en l'espèce sur la face interne de la jupe extérieure 9.The base 3 comprises an outer skirt 9 of cylindrical general shape, directed downwards arranged for and intended to be fixed on the neck of the container, by means of appropriate fastening means complementary to one another, such a protruding flange or thread, provided in this case on the inner face of the outer skirt 9.
Le moyen verseur 4 comporte une paroi cylindrique 10 de plus petit diamètre que la jupe extérieure 9, ayant une partie en regard de la jupe extérieure 9 et une partie 10a saillant axialement de la jupe extérieure 9 vers le haut. Cette partie 10a est limitée à son extrémité sommitale par un bord libre 11 s'étendant sensiblement dans un plan transversal. Sur un peu plus d'un demi-cercle à l'opposé des moyens 7 de pivotement, le bord libre 11 est évasé vers l'extérieur pour former verseur.The pouring means 4 comprises a cylindrical wall 10 of smaller diameter than the outer skirt 9, having a portion facing the outer skirt 9 and a portion 10a projecting axially from the outer skirt 9 upwards. This portion 10a is limited at its summit end by a free edge 11 extending substantially in a transverse plane. On a little more than half a circle opposite the means 7 of pivoting, the free edge 11 is flared outwardly to form pourer.
La partie 10a de la paroi 10 présente une face interne cylindrique lisse 12 et une face externe 13 ayant une partie cylindrique 14 vers le bas, du côté de la jupe extérieure 9, et vers le haut une partie en creux 15, de plus petit diamètre, reliant la partie cylindrique 14 au bord libre 11.The portion 10a of the wall 10 has a smooth cylindrical inner face 12 and an outer face 13 having a cylindrical portion 14 downwards, on the side of the skirt 9, and upwardly a recessed portion 15, of smaller diameter, connecting the cylindrical portion 14 to the free edge 11.
Dans la réalisation représentée, le moyen verseur 4 comporte également d'une part un opercule 16 arrachable empêchant l'accès au contenu du récipient avant une première utilisation et protégeant ce contenu et d'autre part des moyens 17 régulateurs de l'écoulement du contenu du récipient.In the embodiment shown, the pouring means 4 also comprises, on the one hand, a tear-off lid 16 preventing access to the contents of the container before a first use and protecting this content and, on the other hand, means 17 regulating the flow of the contents. of the container.
L'embase 3 présente également un épaulement annulaire 18, transversal, situé entre le haut de la jupe extérieure 9 de l'embase 3 et la partie 10a de la paroi 10 du moyen verseur 4. L'épaulement annulaire 18 présente une face supérieure 18a dans laquelle est ménagée une rainure annulaire de direction axiale, ouverte vers le haut, attenante à la face externe de la partie cylindrique 14 de la paroi 10. Cette rainure forme les premiers moyens de fixation 5.The base 3 also has an annular shoulder 18, transverse, located between the top of the outer skirt 9 of the base 3 and the portion 10a of the wall 10 of the pouring means 4. The annular shoulder 18 has an upper face 18a in which is provided an annular groove of axial direction, open upwards, adjacent to the outer face of the cylindrical portion 14 of the wall 10. This groove forms the first fastening means 5.
Le capot 6 comporte une paroi sommitale transversale 19 - plane dans la réalisation représentée - ayant une face interne 19a tournée vers le bas. Il comporte également, attenante au bord périphérique de la paroi 19, une courte jupe périphérique cylindrique 20, dirigée vers le bas, limitée par un bord libre inférieur 21. La jupe 20, et donc l'ensemble du capot 6, a une hauteur axiale h qui, grâce à la structure du bouchon, peut être réduite, toutes choses égales par ailleurs. Par exemple, pour un bouchon dont l'embase 3 a un diamètre de l'ordre de 3 cm et une hauteur totale de l'ordre de 1 ,5 à 2 cm, la hauteur h peut être de l'ordre de 0,5 cm.The cover 6 has a transverse top wall 19 - planar in the embodiment shown - having an inner face 19a facing downwards. It also comprises, adjacent to the peripheral edge of the wall 19, a short cylindrical peripheral skirt 20, directed downwards, bounded by a lower free edge 21. The skirt 20, and therefore the entire cover 6, has an axial height h which, thanks to the structure of the cap, can be reduced, all things being equal. For example, for a plug whose base 3 has a diameter of about 3 cm and a total height of the order of 1, 5 to 2 cm, the height h may be of the order of 0.5 cm.
De la face interne 19a de Ia paroi sommitale 19 du capot 6 saille vers le bas une collerette 22 de forme générale cylindrique, toute entière située dans la hauteur axiale du capot 6 définie par la hauteur h de la jupe 20. Dans la réalisation représentée, la hauteur axiale de la collerette 22 est de l'ordre d'un peu plus de la moitié, ou de l'ordre des deux tiers, de la hauteur de la jupe 20. Ce faisant, la collerette 22 ne saille pas en dessous du plan transversal défini par le bord libre inférieur 21 de la jupe 20. La collerette 22, qui a un diamètre externe en correspondance avec le diamètre interne de la partie 10a de la paroi 10 vers le bord libre 11 , vient au contact de la face interne 12 de la paroi 10 pour participer à δ l'étanchéité, outre que le bord libre 11 du moyen verseur 4 vient quant à lui au contact de la face interne 19a de la paroi sommitale 19 du capot 6.From the inner face 19a of the top wall 19 of the cover 6 protrudes downwardly a flange 22 of generally cylindrical shape, entirely located in the axial height of the cover 6 defined by the height h of the skirt 20. In the embodiment shown, the axial height of the collar 22 is of the order of a little more than half, or of the order of two-thirds, the height of the skirt 20. In doing so, the collar 22 does not project below the transverse plane defined by the lower free edge 21 of the skirt 20. The flange 22, which has an outer diameter in correspondence with the internal diameter of the portion 10a of the wall 10 towards the free edge 11, comes into contact with the inner face 12 of the wall 10 to participate in δ sealing, in addition to the free edge 11 of the pouring means 4 comes in contact with the inner face 19a of the top wall 19 of the cover 6.
La seconde pièce 2 comporte également une bague formant les seconds moyens périphériques de fixation 8. La bague 8 est logée en remplissant, et maintenue fixement, dans la rainure 5, par emmanchement et grâce à des saillies respectives appropriées, ou par soudage, ou par tout autre moyen. C'est ainsi que les deux pièces 1 et 2 sont associées rigidement entre elles. Dans la réalisation considérée, la bague 8 comporte un talon horizontal supérieur dirigé radialement vers l'extérieur, qui vient sur la face supérieure 18a de l'épaulement annulaire 18, juste au dessus de la jupe extérieure 9 de l'embase 3, de manière à obturer totalement la rainure 5.The second piece 2 also comprises a ring forming the second peripheral attachment means 8. The ring 8 is housed by filling, and fixedly held in the groove 5, by fitting and by respective appropriate projections, or by welding, or by any other way. Thus, the two parts 1 and 2 are rigidly associated with each other. In the embodiment considered, the ring 8 comprises a radially outwardly directed upper horizontal heel, which comes on the upper face 18a of the annular shoulder 18, just above the outer skirt 9 of the base 3, so that to completely close the groove 5.
Il est entendu que la rainure 5 et la bague 8 peuvent faire l'objet de variantes de réalisation entrant dans le champ du brevet, dès lors qu'est remplie la fonction de coopération rigide assurant la fixation respective des deux pièces 1 et 2. Il est entendu également qu'à la rainure 5 et à la bague 8 peuvent être substitués des moyens équivalents.It is understood that the groove 5 and the ring 8 may be the subject of alternative embodiments falling within the scope of the patent, since the rigid cooperation function is fulfilled ensuring the respective attachment of the two parts 1 and 2. It is also understood that the groove 5 and the ring 8 may be substituted with equivalent means.
Le bouchon constitué des deux pièces 1 et 2 comprend deux parties, l'une que l'on peut qualifier de fixe PF - en ce sens qu'elle est fixée rigidement sur le col du récipient - et l'autre que l'on peut qualifier de mobile PM, associées l'une à l'autre par les moyens 7 de pivotement. La partie fixe PM comprend la première pièce 1 et la bague 8, tandis que la partie mobile PM est formée du seul capot 6.The plug consisting of the two parts 1 and 2 comprises two parts, one that can be described as fixed PF - in that it is fixed rigidly on the neck of the container - and the other that we can PM mobile, associated with each other by the means 7 of pivoting. The fixed part PM comprises the first part 1 and the ring 8, while the mobile part PM is formed of the only cover 6.
Les deux parties fixe PF et mobile PM coopèrent tout d'abord comme décrit, en ce que la face interne 19a de la paroi sommitale 19 et la face externe de la collerette 22 du capot 6 viennent au contact, respectivement, du bord libre 11 et de la face interne 12 de la paroi 10 du moyen verseur 4, en participant à l'étanchéité. Ensuite, la jupe périphérique cylindrique 20 entoure à l'extérieur la partie 10a de la paroi 10. Egalement, la partie de la face interne de la jupe 20 du capot 6 attenante à son bord libre inférieur 21 vient au contact de la face externe 13 de la partie cylindrique 14 de la paroi 10 du moyen verseur 4, pour aider au maintien du bouchon en position de fermeture. Réserve faite d'un secteur circulaire dans lequel se trouvent les moyens 7 de pivotement, le bord libre 21 de la jupe 20 est adjacent au bord supérieur de la bague 8, sensiblement dans le plan transversal de l'épaulement 18 qualifié par la suite de plan de jonction P, pour la raison que lorsque l'on regarde Ie bouchon de l'extérieur, le plan P est celui dans lequel le capot 6 et l'embase 3 semblent être adjacents.The two fixed parts PF and mobile PM initially cooperate as described, in that the inner face 19a of the top wall 19 and the outer face of the flange 22 of the cover 6 come into contact, respectively, with the free edge 11 and of the inner face 12 of the wall 10 of the pouring means 4, participating in the seal. Then, the cylindrical peripheral skirt 20 surrounds outside the portion 10a of the wall 10. Also, the portion of the inner face of the skirt 20 of the cover 6 adjacent to its lower free edge 21 comes into contact with the outer face 13 of the cylindrical portion 14 of the wall 10 of the pouring means 4, to help hold the cap in the closed position. Reserve made of a circular sector in which are the means 7 of pivoting, the free edge 21 of the skirt 20 is adjacent to the upper edge of the ring 8, substantially in the transverse plane of the shoulder 18 subsequently qualified junction plane P, for the reason when looking at the cap from the outside, the plane P is the one in which the cover 6 and the base 3 appear to be adjacent.
Les moyens 7 de pivotement, fonctionnellement associés à la partie fixe PF et au capot 6, assurent le pivotement de ce dernier autour d'un axe transversal X, entre deux positions extrêmes, à savoir une position de fermeture stable (figures 1 , 5 et 6) et une position d'ouverture stable (figures 3 et 4). La position extrême d'ouverture résulte d'un pivotement de sensiblement 180° par rapport à la position de fermeture. Le cas échéant, le capot 6 peut être ouvert dans une position intermédiaire, par exemple par suite d'un pivotement à 90° (figure 2). L'axe X est essentiellement virtuel et sa position n'est pas parfaitement fixe mais au contraire se déplace axialement lors de l'ouverture et de la fermeture du bouchon.The pivoting means 7, functionally associated with the fixed part PF and the cover 6, pivot the latter about a transverse axis X, between two extreme positions, namely a stable closing position (FIGS. 6) and a stable opening position (Figures 3 and 4). The extreme open position results from a pivoting of substantially 180 ° with respect to the closed position. If necessary, the cover 6 can be opened in an intermediate position, for example as a result of a 90 ° pivot (FIG. 2). The X axis is essentially virtual and its position is not perfectly fixed but instead moves axially when opening and closing the cap.
Dans la réalisation particulière représentée, les moyens 7 de pivotement comprennent une partie déformable 23 en forme générale de diabolo d'axe transversal parallèle à l'axe X. La partie déformable 23 est délimitée vers le haut par un segment arqué supérieur d'épaisseur réduite 24 formant une zone de plus faible résistance déformable, appartenant à la jupe 20 du capot 6 (partie mobile PM). La partie déformable 23 est délimitée vers le bas par un segment arqué inférieur d'épaisseur réduite 25 formant une zone de plus faible résistance déformable, appartenant à la bague 8 (partie fixe PF). Latéralement de part et d'autre, la partie déformable 23 est limitée à ses deux extrémités transversales par deux bords libres 26, droits et de direction axiale.In the particular embodiment shown, the pivoting means 7 comprise a deformable part 23 in the general shape of a diabolo with a transverse axis parallel to the axis X. The deformable part 23 is delimited upwards by an upper arcuate segment of reduced thickness. 24 forming an area of lower deformable resistance, belonging to the skirt 20 of the cover 6 (mobile part PM). The deformable portion 23 is delimited downwards by a lower arcuate segment of reduced thickness 25 forming a zone of lower deformable resistance, belonging to the ring 8 (fixed part PF). Laterally on either side, the deformable portion 23 is limited at its two transverse ends by two free edges 26, straight and axial direction.
Lors du mouvement d'ouverture du capot 6 à partir de sa position de fermeture, l'axe X de pivotement est d'abord situé à l'endroit ou au voisinage du segment arqué supérieur 24. A ce moment, la collerette 22, de petite longueur axiale, peut échapper de la paroi 10. Puis, la partie déformable 23 en forme de diabolo est déformée en étant incurvée vers l'extérieur. Pour la fin du mouvement d'ouverture, l'axe X de pivotement se trouve à l'endroit ou au voisinage du segment arqué inférieur 25. Ainsi, lors du mouvement d'ouverture, l'axe X de pivotement est généralement déplacé vers le bas. En position d'ouverture totale à 180°, la partie déformable 23 en forme de diabolo, légèrement incurvée à concavité dirigée vers le bas, est située sensiblement dans un plan transversal voisin du plan de la paroi sommitale 19 du capot 6.During the opening movement of the cover 6 from its closed position, the pivoting axis X is first located at or near the upper arched segment 24. At this moment, the collar 22, of small axial length, can escape the wall 10. Then, the deformable portion 23 shaped diabolo is deformed being curved outwardly. For the end of the opening movement, the pivoting axis X is at or near the lower arched segment 25. Thus, during the opening movement, the pivot axis X is usually moved down. In the fully open position at 180 °, the deformable portion 23 in the form of a diabolo, slightly curved with concavity directed downwards, is located substantially in a transverse plane adjacent to the plane of the top wall 19 of the cover 6.
De part et d'autre du segment arqué supérieur 24, et sur deux petits secteurs circulaires - en l'espèce de quelques degrés ou d'une dizaine de degrés -, le bord libre inférieur 21 de la jupe 20 du capot 6 définit un segment 27 dirigé vers la paroi sommitale 19 et s'étendant jusqu'à proximité de celle-ci. Dans Ia réalisation représentée, les deux segments 27 ont chacun une forme générale très légèrement arrondie et leurs liaisons avec le reste du bord libre 21 de la jupe 20 et avec le segment arqué supérieur 24 sont également arrondies. Ainsi, à l'endroit des segments 27, la hauteur axiale de la jupe 20 est diminuée et les deux segments 27 délimitent deux parties vides 28.On either side of the upper arcuate segment 24, and on two small circular sectors - in this case a few degrees or ten degrees -, the lower free edge 21 of the skirt 20 of the hood 6 defines a segment 27 directed towards the top wall 19 and extending to near it. In the embodiment shown, the two segments 27 each have a very slightly rounded overall shape and their connections with the rest of the free edge 21 of the skirt 20 and with the upper arcuate segment 24 are also rounded. Thus, at the location of the segments 27, the axial height of the skirt 20 is reduced and the two segments 27 delimit two empty portions 28.
De part et d'autre du segment arqué inférieur 25, et sur deux petits secteurs circulaires correspondants aux secteurs des deux segments 27 et des deux parties vides 28, la hauteur axiale de la bague 8 est augmentée, la bague 8 saillant axialement à l'extérieur et au dessus de la rainure 5, de manière à former ainsi une sorte de triangle rectangle curviligne 29. Un tel triangle rectangle curviligne 29 est limité sur son premier côté de plus grande longueur opposé à l'angle droit par un segment 30, adjacent et complémentaire du segment 27 placé en regard. Sur un deuxième côté de plus petite longueur, le triangle curviligne 29 est limité par un bord droit 31, de direction générale axiale, adjacent du bord libre d'extrémité 26 de la partie déformable 23. Le troisième côté du triangle curviligne 29 correspond à la prolongation de la partie principale de la bague 8. Les deux zones élargies de la bague 8 en forme de triangle curviligne 29 se logent de façon complémentaire dans les deux parties vides 28.On either side of the lower arcuate segment 25, and on two small circular sectors corresponding to the sectors of the two segments 27 and the two empty parts 28, the axial height of the ring 8 is increased, the ring 8 projecting axially to the outside and above the groove 5, so as to form a sort of rectangle curvilinear triangle 29. Such a curvilinear rectangle 29 is limited on its first longer side opposite the right angle by a segment 30, adjacent and complementary to the segment 27 placed opposite. On a second side of smaller length, the curvilinear triangle 29 is bounded by a straight edge 31 of axial general direction, adjacent to the free end edge 26 of the deformable portion 23. The third side of the curvilinear triangle 29 corresponds to the extension of the main part of the ring 8. The two enlarged areas of the ring 8 in the form of a curvilinear triangle 29 are housed in a complementary manner in the two empty parts 28.
Le segment arqué supérieur 24 est situé à proximité de la paroi sommitale 19 du capot 6 - notamment à proximité immédiate - et Ie segment arqué inférieur 25 est situé à proximité - notamment à proximité immédiate - de l'épaulement annulaire 18. Ainsi, la partie déformable 23 en forme de diabolo s'étend en direction axiale sur une hauteur totale de l'ordre de la hauteur h de la jupe 20. Compte tenu que le segment arqué inférieur 25 est situé sensiblement dans le plan de jonction P, les moyens 7 de pivotement se trouvent situés substantiellement tout entier entre le plan défini par la paroi sommitale 19 du capot 6 et le plan de jonction P. Le bouchon est ainsi de hauteur axiale limitée et réalisé avec une quantité moindre de matière plastique.The upper arcuate segment 24 is located near the top wall 19 of the cover 6 - especially in the immediate vicinity - and the lower arcuate segment 25 is located close to - especially in the immediate vicinity of - the annular shoulder 18. Thus, the part deformable 23 diabolo-shaped extends in the axial direction over a total height of the order of the height h of the skirt 20. Given that the lower arcuate segment 25 is located substantially in the junction plane P, the pivoting means 7 are located substantially entirely between the plane defined by the top wall 19 of the cover 6 and the junction plane P. The cap is thus high limited axial and made with a smaller amount of plastic material.
Grâce aux deux fentes axiales existant de part et d'autre des moyens 7 de pivotement, définies chacune par un bord libre 26 de la partie déformable 23 et le bord 31 en regard du triangle curviligne 29, la partie 23 en forme de diabolo peut être déformée en s'incurvant vers l'extérieur et, en position d'ouverture totale, être située sensiblement dans ou au voisinage d'un plan transversal voisin du plan de la paroi sommitale 19.Thanks to the two axial slots existing on either side of the pivoting means 7, each defined by a free edge 26 of the deformable part 23 and the edge 31 facing the curvilinear triangle 29, the diaboloid-shaped part 23 can be deformed by curving outwards and, in the fully open position, be located substantially in or near a transverse plane adjacent to the plane of the top wall 19.
Sur un secteur circulaire légèrement plus grand que celui où se trouvent les moyens 7 de pivotement et les deux triangles curvilignes 29 de la bague 8, la face externe de la paroi 10 du moyen verseur 4 est dépourvue de la partie en creux telle que 15 et, au contraire, prolonge la partie cylindrique 14, pour former une face 32 en forme générale de secteur cylindrique. La face 32 est limitée vers le bas par l'épaulement 18 et vers le haut par un secteur circulaire - en l'espèce de l'ordre de 90° - du bord libre 11.In a circular sector slightly larger than that in which the pivoting means 7 and the two curvilinear triangles 29 of the ring 8 are located, the outer face of the wall 10 of the pouring means 4 is devoid of the recessed portion such that 15 and on the contrary, extends the cylindrical portion 14, to form a face 32 in the general shape of a cylindrical sector. The face 32 is limited downwards by the shoulder 18 and upwards by a circular sector - in this case of the order of 90 ° - of the free edge 11.
La face 32 est limitée latéralement, de part et d'autre, par un segment latéral 33, légèrement incurvé, s'étendant de façon adjacente au segment 27 de la jupe 20 et au segment 30 du triangle curviligne 29 de la bague 8.The face 32 is laterally limited, on either side, by a slightly curved lateral segment 33 extending adjacent to the segment 27 of the skirt 20 and to the segment 30 of the curvilinear triangle 29 of the ring 8.
La face 32 est une contrepartie contre laquelle sont placés, vers l'extérieur, les moyens 7 de pivotement et les deux triangles curvilignes 29. Ainsi, les vides existant autour des moyens 7 de pivotement et des triangles curvilignes 29 sont masqués et la pénétration de pollution d'origine extérieure vers la zone de versage est évitée.The face 32 is a counterpart against which are placed, outwardly, the means 7 of pivoting and the two curvilinear triangles 29. Thus, the voids existing around the pivoting means 7 and the curvilinear triangles 29 are masked and the penetration of pollution from outside to the pouring area is avoided.
Selon une réalisation possible, le bouchon comporte également des moyens extérieurs 34 assurant l'inviolabilité avant une première ouverture, interposés entre la partie fixe PF et la partie mobile PM. Ces moyens 34 sont réalisés sous la forme de ponts frangibles, reliant le bord libre inférieur 21 de la jupe 20 au bord supérieur en regard et adjacent de la bague 8. Les ponts frangibles 34 sont conçus pour être rompus lorsque, lors de la première ouverture du capot 6, l'utilisateur tire axialement vers le haut sur le capot 6 à l'opposé des moyens 7 de pivotement. Selon une autre variante de réalisation, les ponts frangibles 34 peuvent être remplacés par une ligne ou une zone de plus faible résistance. Il importe de souligner que cette réalisation assure l'inviolabilité avant une première ouverture, sans générer de déchet gênant à l'occasion de cette première ouverture.According to one possible embodiment, the cap also comprises external means 34 ensuring the inviolability before a first opening, interposed between the fixed part PF and the mobile part PM. These means 34 are made under the form of frangible bridges, connecting the lower free edge 21 of the skirt 20 to the upper edge opposite and adjacent to the ring 8. The frangible bridges 34 are designed to be broken when, at the first opening of the cover 6, the user pulls axially upwards on the cover 6 opposite the means 7 of pivoting. According to another embodiment, the frangible bridges 34 may be replaced by a line or a zone of lower resistance. It is important to underline that this realization ensures the inviolability before a first opening, without generating troublesome waste on the occasion of this first opening.
Le cas échéant, de façon alternative ou supplémentaire, les moyens extérieurs assurant l'inviolabilité avant une première ouverture sont un manchon ou une gaine en film de matière plastique entourant l'embase 3 et le capot 6.If necessary, alternatively or additionally, the external means ensuring the inviolability before a first opening are a sleeve or a sheath made of plastic film surrounding the base 3 and the cover 6.
Dans une réalisation possible et représentée, le bouchon comporte également l'opercule arrachable 16 qui constitue des moyens intérieurs assurant l'inviolabilité avant une première ouverture. Dans la mesure où le capot est transparent, comme indiqué, l'utilisateur peut constater que l'opercule 16 est bien en place et n'a pas été enlevé.In a possible embodiment and shown, the cap also comprises the tear-off cap 16 which constitutes internal means ensuring the inviolability before a first opening. Insofar as the cover is transparent, as indicated, the user can see that the cover 16 is in place and has not been removed.
L'opercule 16 est constitué par un fond discoïde transversal, amovible fermant le moyen verseur 4, dont le bord périphérique est relié à la face interne 12 de la paroi 10 du moyen verseur 4, au dessus des moyens régulateurs 17, en l'espèce dans un plan situé légèrement en dessous du plan P, par une ligne ou zone de plus faible résistance, de manière à pouvoir être déchiré par suite d'une traction suffisante de l'utilisateur, une fois le capot 6 ouvert, puis enlevé. Au disque de l'opercule 16 est fixé, au dessus, un anneau 35 de préhension facilitant l'arrachage de l'opercule 16 par l'utilisateur.The cover 16 is constituted by a removable transverse discoid bottom closing the pouring means 4, whose peripheral edge is connected to the inner face 12 of the wall 10 of the pouring means 4, above the regulating means 17, in this case in a plane located slightly below the plane P, by a line or zone of lower resistance, so that it can be torn due to sufficient traction of the user, once the cover 6 open, then removed. The disc of the lid 16 is fixed above a gripping ring 35 facilitating the tearing of the lid 16 by the user.
Dans la réalisation représentée, les moyens 17 régulateurs de l'écoulement du contenu du récipient sont constitués d'une multiplicité de parties (communément appelées « pétales »), s'étendant à partir de la face interne 12 de la paroi 10 du moyen verseur 4, légèrement en dessous de l'opercule 16, en étant dirigées vers l'axe Z, réparties sensiblement uniformément autour du dit axe, légèrement dirigées vers le bas, et laissant libre des espaces de passage entre elles et centralement.In the embodiment shown, the means 17 regulating the flow of the contents of the container consist of a multiplicity of parts (commonly called "petals"), extending from the inner face 12 of the wall 10 of the pouring means 4, slightly below the cap 16, being directed towards the Z axis, distributed substantially uniformly around said axis, slightly directed downwards, leaving free passage spaces between them and centrally.
Dans la réalisation représentée, le capot 6 comporte sur la face externe de sa jupe 20, diamétralement à l'opposé des moyens 7 de pivotement, une petite saillie 36 dirigée transversalement vers l'extérieur offrant une prise pour l'utilisateur afin de faciliter l'ouverture du capot 6.In the embodiment shown, the cover 6 has on the outer face of its skirt 20, diametrically opposite the means 7 of pivoting, a small projection 36 directed transversely outwardly providing a grip for the user to facilitate the opening the hood 6.
Pour la fabrication du bouchon, on moule par injection séparément les deux pièces 1 et 2 - la seconde pièce 2 pouvant être moulée fermée - puis on assemble rigidement entre elles deux pièces 1 et 2 par enfoncement ou par soudage ou par tout autre moyen. Le bouchon ainsi réalisé peut être monté sur un récipient une fois rempli. Il est à noter que dans la réalisation décrite, il est nécessaire d'orienter les deux pièces 1 et 2 autour de l'axe Z pour les assembler, pou amener les moyens 7 de pivotement de la pièce 1 et les deux triangles curvilignes 29 en coïncidence avec le secteur cylindrique 32 de la pièce 2. For the manufacture of the cap, the two parts 1 and 2 - the second part 2 which can be molded closed - are molded separately by injection and then two parts 1 and 2 are rigidly assembled between them by penetration or by welding or by any other means. The cap thus produced can be mounted on a container once filled. It should be noted that in the embodiment described, it is necessary to orient the two parts 1 and 2 about the Z axis to assemble them, to bring the means 7 of pivoting of the workpiece 1 and the two curvilinear triangles 29 into coincidence with cylindrical sector 32 of part 2.
