The base comprises a lower skirt provided with a thread or an attachment cord for attachment to a container, a pouring well, and an annular groove defining a mounting axis and provided with an elastically hooking relief. deformable device. The cover is provided with a fastening ring inserted into the groove and held in position by the engaging relief, a cap provided with a closure wall and at least one sealing skirt. and a hinge hinge between the ring and the cap, the hinge being reversibly movable from a closed position to an open position, allowing movement of the cap relative to the ring respectively of a position d opening giving access to the well to a closed position in which the sealing skirt cooperates with the base and the closure wall covers the well.
[0003] Lors du montage des deux pièces, le capot doit être positionné angulairement par rapport à l'embase dans un plan
perpendiculaire à l'axe géométrique de montage, ce qui rend le montage complexe et onéreux.When mounting the two parts, the cover must be positioned angularly relative to the base in a plane perpendicular to the geometric axis of assembly, which makes mounting complex and expensive.
EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION
[0004] L'invention vise à faciliter le montage d'un bouchon en deux pièces, du type décrit ci-dessus. Pour ce faire, il est proposé selon l'invention un bouchon comportant :The invention aims to facilitate the assembly of a two-piece plug, of the type described above. To do this, it is proposed according to the invention a cap comprising:
- une première pièce constituant une embase et comportant : - une jupe inférieure munie de moyens de fixation à un récipient,a first part constituting a base and comprising: a lower skirt provided with means for fixing to a container,
- Un puit verseur,- A pouring well,
- une gorge annulaire définissant un axe géométrique de montage, - un relief d'accrochage élastiquement déformable,an annular groove defining a geometric mounting axis; an elastically deformable hooking projection,
- une deuxième pièce constituant un capot comportanta second component constituting a hood comprising
- une bague de fixation insérée dans ladite gorge et maintenue en position par ledit relief d'accrochage,a fixing ring inserted into said groove and held in position by said hooking relief,
- un capuchon pourvu d'une paroi sommitale d'obturation et d'au moins une jupe d'étanchéité, - des moyens de pivotement du capuchon par rapport a la bague entre une position d'ouverture donnant accès audit puits verseur et une position d'obturation dans laquelle la jupe d'étanchéité coopère avec l'embase et la paroi d'obturation recouvre ledit puits.a cap provided with a top closure wall and at least one sealing skirt, means for pivoting the cap relative to the ring between an open position giving access to said pouring well and a position of shutter in which the sealing skirt cooperates with the base and the closure wall covers said well.
[0005] Selon l'invention, le bouchon se caractérise par le fait que le capot comporte une butée et l'embase comporte une
contrebutée coopérant avec la butée pour indexer une position angulaire de l'embase par rapport au capot autour d'un axe de montage .According to the invention, the cap is characterized in that the cover comprises a stop and the base comprises a abutment cooperating with the abutment to index an angular position of the base relative to the cover around a mounting axis.
[0006] La coopération entre la butée et la contrebutée permet de présenter les deux pièces constitutives du bouchon sans avoir déterminé au préalable leur position angulaire respective, puis de les faire tourner l'une par rapport à l'autre autour de l'axe de montage en les rapprochant dans l'axe de montage jusqu'à ce que le mouvement de rotation soit interrompu par la rencontre de la butée et de la contrebutée.The cooperation between the abutment and the abutment makes it possible to present the two component parts of the cap without having previously determined their respective angular position, then to rotate them relative to each other about the axis of mounting them closer to the mounting axis until the rotational movement is interrupted by the meeting of the stop and the abutment.
[0007] Ainsi réalisé, le bouchon offre l'assurance d'un positionnement angulaire précis du capuchon sur l'embase.Thus realized, the plug offers the assurance of precise angular positioning of the cap on the base.
[0008] Selon un mode de réalisation, la butée interfère élastiquement avec le puits verseur en position d'ouverture ou dans une position intermédiaire entre la position de d'obturation et la position d'ouverture, pour maintenir le capuchon en position ou guider le capuchon dans son mouvement. Le même relief assure ainsi une double fonction, lors du montage et lors de l'utilisation ultérieure. La butée peut comporter une rampe qui facilite son guidage par rapport au puits verseur.According to one embodiment, the abutment interferes elastically with the pouring well in the open position or in an intermediate position between the closed position and the open position, to hold the cap in position or to guide the hood in his movement. The same relief ensures a dual function, during assembly and during subsequent use. The stop may include a ramp which facilitates its guidance relative to the pouring well.
[0009] Avantageusement, l'embase comporte un opercule fermant le puits de versement. Cet opercule permet de préserver le contenu du récipient avant la première ouverture et constitue un témoin d'inviolabilité. Cet opercule peut être arrachable et muni d'un anneau de préhension.Advantageously, the base comprises a lid closing the pouring well. This seal makes it possible to preserve the contents of the container before the first opening and constitutes a tamper evidence. This lid can be removed and provided with a gripping ring.
[0010] Dans le cadre d'un mode de réalisation, on prévoit que l'opercule présente une pluralité de disques de diamètre inférieur au diamètre de l'opercule, lesdits disques présentant une bordure de délimitation dans l'épaisseur dudit opercule réalisée par un rétrécissement de matière. Dans le
cadre de ce mode de réalisation, on peut prévoir que l'anneau de préhension est relié à chacun des disques par une patte.In the context of one embodiment, it is provided that the lid has a plurality of disks of diameter less than the diameter of the lid, said disks having a delimiting border in the thickness of said lid made by a shrinkage of matter. In the In this embodiment, it can be provided that the gripping ring is connected to each of the disks by a tab.
[0011] Avantageusement, la bague est reliée au capuchon par des ponts frangibles. Les ponts constituent un témoin d'inviolabilité visible avant la première ouverture du bouchon.Advantageously, the ring is connected to the cap by frangible bridges. The bridges constitute a tamper evident witness before the first opening of the cap.
[0012] Selon un autre aspect de l'invention, celle-ci a trait à un procédé de montage d'un bouchon selon l'une quelconque des revendications précédentes . Conformément à l'invention, le procédé comporte les étapes suivantes :According to another aspect of the invention, it relates to a method of mounting a plug according to any one of the preceding claims. According to the invention, the method comprises the following steps:
- disposition desdites deux pièces de manière coaxiale suivant un axe Z donné,- Arrangement of said two parts coaxially along a given axis Z,

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION [0016] Les deux modes de réalisation du bouchon selon l'invention qui vont maintenant être décrits sont réalisés en matière plastique et présentent un axe général de révolution Z (figures 5 et 10).DETAILED DESCRIPTION OF AN EMBODIMENT [0016] The two embodiments of the plug according to the invention which will now be described are made of plastic and have a general axis of revolution Z (FIGS. 5 and 10).
[0017] Ils sont typiquement destinés 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.They are 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.
[0018] Dans la réalisation représentée, le bouchon comprend une première pièce 1 et une seconde pièce 2 destinées à être associées rigidement l'une à l'autre.In the embodiment shown, the cap comprises a first part 1 and a second part 2 intended to be rigidly associated with one another.
[0019] La première pièce 1 - par exemple en polyéthylène - forme une embase périphérique 3 (figure 3) ou une embase 3' (figure 8) et un moyen verseur 4 (figure 3) ou un moyen verseur 4' (figure 8). Elle inclut également des premiers moyens 5 ou 5' (respectivement figures 3 et 8) périphériques de fixation pour la seconde pièce 2.The first part 1 - for example polyethylene - forms a peripheral base 3 (Figure 3) or a base 3 '(Figure 8) and a pouring means 4 (Figure 3) or a pouring means 4' (Figure 8) . It also includes first means 5 or 5 '(respectively FIGS. 3 and 8) fixing peripherals for the second part 2.
[0020] La seconde pièce 2 - par exemple en polypropylène transparent - forme un capot 6 (figure 1) et, des moyens 7 de pivotement du capot 6 et des seconds moyens 8 périphériques de fixation complémentaires des premiers moyens 5 et 5 'de fixation.The second part 2 - for example transparent polypropylene - forms a cover 6 (Figure 1) and, means 7 for pivoting the cover 6 and second means 8 peripheral fasteners complementary to the first means 5 and 5 'of attachment .
[0021] Le bouchon est décrit en supposant l'axe Z vertical, l'embase 3 (ou 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 a 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 axis Z, the base 3 (or 3 ') down and the hood 6 to the top. 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 "transverse" refers to what is perpendicular to the Z axis. Depending on the context, the word "internal" (or "inner") refers to what is located in the plug 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.
[0022] L'embase 3 comporte une jupe inférieure 9 ou 9 ' (respectivement figures 3 et 8) 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. Ces moyens de fixation sont partiellement représentés sur les figures 5 et 10 par les éléments portant la référence 40.The base 3 comprises a lower skirt 9 or 9 '(respectively Figures 3 and 8) of generally cylindrical shape, directed downwards arranged for and intended to be fixed on the neck of the container, by means of suitable fasteners complementary to one another, such as a protruding flange or a thread, provided in this case on the inner face of the outer skirt 9. These fastening means are partially shown in FIGS. 10 by the elements bearing the reference 40.
[0023] 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 le moyen 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 the pouring means.
[0024] La partie 10a de la paroi 10 présente une face interne cylindrique lisse 12 et une face externe 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 having a cylindrical portion 14 downwards, on the side of the outer skirt 9, and upwardly a recessed portion 15, in addition small diameter, connecting the cylindrical portion 14 to the free edge 11.
[0025] Dans la réalisation représentée sur les figures 3, 4, 5 et 6, 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 (figure 5).In the embodiment shown in Figures 3, 4, 5 and 6, 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 (Figure 5).
[0026] L'opercule 16 constitue un moyen pour obturer un puits 50, ledit puits 50 traversant axialement l'embase 3 et constituant un moyen verseur qui livre passage au liquide contenu dans le récipient quand il est délivré.The lid 16 is a means for closing a well 50, said well 50 axially passing through the base 3 and constituting a pouring means that delivers passage to the liquid contained in the container when it is delivered.
[0027] 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 duThe 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
-moyen - verseur- 4-.-—L^-épaulement—annulaire 18 constitue un relief d'accrochage élastiquement déformable d'une partie du capot 6.-moyen - poureur- 4 -.-- The -auaement-annular 18 is an elastically deformable hooking relief of a portion of the cover 6.
[0028] Au voisinage de l' épaulement 18, l'embase présente une partie supérieure dans laquelle est ménagée une gorge annulaire 5, ouverte vers le haut, attenante à la face externe de la partie cylindrique 14 de la paroi 10. Cette gorge annulaire forme les premiers moyens de fixation 5.In the vicinity of the shoulder 18, the base has an upper portion in which is formed an annular groove 5, open upward, adjacent to the outer face of the cylindrical portion 14 of the wall 10. This annular groove forms the first fastening means 5.
[0029] 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 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 peut être de l'ordre de 0,5 cm.The cover 6 has a transverse top wall 19 - flat 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 which, thanks to the structure of the cap, can be reduced, all things being equal otherwise. 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 may be of the order of 0.5 cm .
[0030] De la face interne 19a de la paroi sommitale 19 du capot 6 saille vers le bas une jupe d'étanchéité 22 de forme générale cylindrique, toute entière située dans la hauteur axiale du capot 6 définie par la hauteur de la jupe 20.The inner face 19a of the top wall 19 of the cover 6 protrudes downwardly a sealing skirt 22 of generally cylindrical shape, entirely located in the axial height of the cover 6 defined by the height of the skirt 20.
[0031] La jupe d'étanchéité 22 du capot 6, 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 de l'embase 3 pour participer à 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.The sealing skirt 22 of the cover 6, 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. of the base 3 to participate in sealing, in addition to the free edge 11 of the pouring means 4 comes into contact with the inner face 19a of the top wall 19 of the cover 6.
[0032] La- seconde-pièce ~2-comporte également une bague 80 formant les seconds moyens périphériques de fixation 8. La bague 80 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 80 comporte un talon horizontal supérieur dirigé radialement vers l'extérieur, qui vient sur la face supérieure 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 80 forming the second peripheral attachment means 8. The ring 80 is housed by filling, and held firmly in the groove 5, by fitting and through respective protrusions appropriate, or by welding, or by any other means. Thus, the two parts 1 and 2 are rigidly associated with each other. In the embodiment considered, the ring 80 has a radially outwardly directed upper horizontal bead, which comes on the upper face of the annular shoulder 18, just above the outer skirt 9 of the base 3, so that to completely close the groove 5.
[0033] II est entendu que la rainure 5 et la bague 80 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.
[0034] Le bouchon est constitué des deux pièces 1 et 2 comprend deux parties, l'une que l'on peut qualifier de fixe - en ce sens qu'elle est fixée rigidement sur le col du récipient - et l'autre que l'on peut qualifier de mobile, associées l'une à l'autre par les moyens 7 de pivotement, les moyens 7 formant charnière entre la bague 80 et la jupe 20 du capot 6. La partie fixe comprend la première pièce 1 et la bague 80, tandis que la partie mobile est formée d'une partie 60 du capot 6, cette partie formant capuchon.It is understood that the groove 5 and the ring 80 may be the subject of alternative embodiments within the scope of the patent, since the rigid cooperation function is fulfilled ensuring the respective attachment of the two parts 1 and 2. The cap consists of two parts 1 and 2 comprises two parts, one that can be described as fixed - in that it is rigidly fixed on the neck of the container - and the other that one can qualify as mobile, associated with each other by the means 7 of pivoting, the means 7 forming a hinge between the ring 80 and the skirt 20 of the cover 6. The fixed part comprises the first part 1 and the ring 80, while the movable portion is formed of a portion 60 of the cover 6, this cap portion.
[0035] Les deux parties fixe et mobile coopèrent tout d'abord comme décrit, en ce que la face interne 19a de la paroi sommitale 19 et la face externe de la jupe d'étanchéité 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 partieThe two fixed and movable parts cooperate firstly as described, in that the inner face 19a of the top wall 19 and the outer face of the sealing skirt 22 of the cover 6 come into contact, respectively, with the free edge 11 and the inner face 12 of the wall 10 of the pouring means 4, participating in the seal. Then, the cylindrical peripheral skirt 20 surrounds the outside part
10a._de_la.. paro.i 10_,._Egaiement, 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 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, pour la raison que lorsque l'on regarde le bouchon de l'extérieur, le plan de jonction est celui dans lequel le capot 6 et l'embase 3 semblent être adjacents.Similarly, the portion of the inner face of the skirt 20 of the cover 6 adjoining its lower free edge 21 comes into contact with the outer face of the cylindrical portion 14 of the wall 10 of the housing. medium pourer 4, to help maintain 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, for the reason that when looking at the cap from the outside, the junction plane is one in which the cover 6 and the base 3 appear to be adjacent.
[0036] Les moyens 7 de pivotement, fonctionnellement associés à la partie fixe 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 et une position d'ouverture stable. L'axe X,
perpendiculaire à l'axe Z et parallèle au plan des figures 5 et 10 , 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. 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°.The pivoting means 7, operatively associated with the fixed part and the cover 6, provide the pivoting of the latter around a transverse axis X, between two extreme positions, namely a stable closed position and a position of stable opening. The X axis, perpendicular to the Z axis and parallel to the plane of Figures 5 and 10, is essentially virtual and its position is not perfectly fixed but instead moves axially when opening and closing the cap. 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 ° pivoting.
[0037] De part et d'autre des moyens de pivotement 7, 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 dirigé vers la paroi sommitale 19 et s 'étendant jusqu'à proximité de celle-ci. Dans la réalisation représentée, les deux segments 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, la hauteur axiale de la jupe 20 est diminuée et les deux segments délimitent deux parties vides 28.On both sides of the pivoting means 7, and 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 directed towards the top wall 19 and extending to near it. In the embodiment shown, the two segments 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, the axial height of the skirt 20 is reduced and the two segments delimit two empty portions 28.
[0038] De part et d'autre des moyens de pivotement 7, et sur deux petits secteurs circulaires correspondant aux secteurs des deux segments et des deux parties vides 28, la hauteur axiale de la bague 80 est augmentée, la bague 80 saillant axialement à l'extérieur et au dessus de la rainure 5, de manière à former ainsi de part et d'autre des moyens de pivotement une sorte de triangle rectangle curviligne 27.On either side of the pivoting means 7, and on two small circular sectors corresponding to the sectors of the two segments and the two empty parts 28, the axial height of the ring 80 is increased, the ring 80 projecting axially to outside and above the groove 5, so as to form on either side of the pivoting means a sort of curvilinear rectangle triangle 27.
[0039] La fonction des moyens de pivotement 7, des triangles rectangles 27 et des parties vides 28 est exposée dans la demande de brevet évoquée précédemment PCT/FR06/001553.
[0040] L'embase 3 comporte également un col 32 destiné à être disposé en regard des moyens de pivotement 7 du capot 6 lorsque le capot est monté sur l'embase.The function of the pivoting means 7, right triangles 27 and empty parts 28 is disclosed in the previously mentioned patent application PCT / FR06 / 001553. The base 3 also comprises a neck 32 intended to be disposed opposite the pivoting means 7 of the cover 6 when the cover is mounted on the base.
[0041] Le col 32 est saillant de la partie cylindrique 14 de l'embase et a pour fonction de faire barrage aux impuretés pouvant s'introduire dans le bouchon par les parties vides 28 du capuchon.The neck 32 is protruding from the cylindrical portion 14 of the base and serves to block the impurities that can be introduced into the cap by the empty parts 28 of the cap.
[0042] Pour indexer la position angulaire du col 32 par rapport aux parties vides 28 du capuchon, la jupe d'étanchéité 22 du capot est réalisée de telle manière que, ponctuellement, elle forme une patte 70 (particulièrement visible sur la figure 2) dirigée vers le bas, ladite patte étant réalisée au voisinage de l'une des parties vides 28.To index the angular position of the neck 32 relative to the empty parts 28 of the cap, the sealing skirt 22 of the cover is made in such a way that, punctually, it forms a tab 70 (particularly visible in Figure 2) directed downwards, said tab being made in the vicinity of one of the empty parts 28.
[0043] Parallèlement, l'embase présente une cale 71 saillante sur la face interne 12 de la paroi 10 de l'embase 3 et -vi-s-ible- en- par-tieul-ie-r—sur la—figure 4. La cale 71 est réalisée au voisinage du col 32.In parallel, the base has a shim 71 protruding on the inner face 12 of the wall 10 of the base 3 and -vi-s-ible- in-between-th-ie-r-on-Figure 4 The wedge 71 is made in the vicinity of the neck 32.
[0044] La patte 70 du capot 6 forme une butée et la cale 71 de l'embase forme une contrebutée. Le capot se trouve positionné correctement par rapport à l'embase quand la patte formant butée entre en contact avec la cale formant en contrebutée .The tab 70 of the cover 6 forms a stop and the wedge 71 of the base forms a buttress. The cover is positioned correctly relative to the base when the tab forming the abutment comes into contact with the wedge forming abutment.
[0045] Ainsi, la butée 70 du capot et la contrebutée 71 de l'embase coopèrent pour indexer la position angulaire de l'embase par rapport au capot, dans un sens de rotation au moins par rapport à l'axe Z, en l'occurrence le sens horaire qui constitue un sens d'indexation.Thus, the stop 70 of the cover and the abutment 71 of the base cooperate to index the angular position of the base relative to the cover, in a direction of rotation at least with respect to the Z axis, in the 'occurrence clockwise which constitutes a direction of indexation.
[0046] Comme le montre la figure 1, la butée 70 comporte une rampe 72.
[0047] De même, comme le montre la figure 4 ou la figure 9, la contrebutée comporte une rampe 73.As shown in Figure 1, the stop 70 includes a ramp 72. Similarly, as shown in FIG. 4 or FIG. 9, the abutment comprises a ramp 73.
[0048] La butée 70 est réalisée de telle manière que, quand le capuchon est en position d'ouverture, la butée interfère avec le bord du puits 50. La butée constitue ainsi une patte de maintien du capuchon en position ouverte, ou partiellement ouverte.The stop 70 is made such that when the cap is in the open position, the stop interferes with the edge of the well 50. The stop thus constitutes a cap holding tab in the open position, or partially open .
[0049] Pour ce faire, on prévoit que la longueur de la butée soit au moins égale à la moitié de la hauteur de la jupe 20 du capuchon 6, comme on peut le voir sur la figure 1.To do this, it is expected that the length of the stop is at least equal to half the height of the skirt 20 of the cap 6, as can be seen in Figure 1.
[0050] Selon une réalisation possible, le bouchon peut comporter également des moyens assurant l'inviolabilité avant une première ouverture, interposés entre la jupe 20 du capot et la bague 80. Ces moyens d'inviolabilité n'ont pas été représentés de sorte à simplifier la compréhension des figures-. -Ils -sont—usuellement- réalisés sous la forme de ponts frangibles.According to a possible embodiment, the cap may also comprise means ensuring the inviolability before a first opening, interposed between the skirt 20 of the cover and the ring 80. These tamperproof means have not been represented so as to simplify the understanding of the figures-. They are usually made in the form of frangible bridges.
[0051] On fera maintenant plus particulièrement référence aux figures 1 à 6 pour décrire le premier mode de réalisation de l'embase destinée à être fixée sur le col de bouteilles d'huile alimentaire.We will now more particularly refer to Figures 1 to 6 to describe the first embodiment of the base to be fixed on the neck of food oil bottles.
[0052] Suivant ce premier mode de réalisation, et comme indiqué ci-avant, l'opercule arrachable 16 constitue des moyens intérieurs assurant l'inviolabilité avant une première ouverture. Dans la mesure où le capot est transparent, comme indiqué ci-avant, l'utilisateur peut constater que l'opercule 16 est bien en place et n'a pas été enlevé.According to this first embodiment, and as indicated above, the tear-off lid 16 constitutes internal means ensuring the inviolability before a first opening. Insofar as the cover is transparent, as indicated above, the user can see that the cover 16 is in place and has not been removed.
[0053] 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 paroiThe lid 16 is constituted by a transversal discoid bottom, removable closing the pouring means 4, the peripheral edge is connected to the inner face 12 of the wall
10 du moyen verseur 4, au-dessus des moyens régulateurs 17,
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 1 'utilisateur .10 of the pouring means 4, above the regulating means 17, by a line or zone of lower strength, so that it can be torn due to sufficient traction of the user, once the cover 6 open, then removed. To the disc of the lid 16 is fixed, above, a gripping ring 35 facilitating the tearing of the lid 16 by the user.
[0054] Dans la réalisation représentée, les moyens 17 (figure 5) régulateurs de l'écoulement d'une huile alimentaire 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 (FIG. 5) regulating the flow of a cooking oil consist of a multiplicity of parts (commonly called "petals"), extending from the internal face 12 of the wall 10 of the pouring means 4, slightly below the cover 16, being directed towards the Z axis, distributed substantially uniformly about said axis, slightly directed downwards, and leaving free passage spaces between they and centrally.
[0055] L'invention n'est toutefois pas limitée à être mise en œuvre sur un bouchon comportant uniquement l'embase qui est représentée sur les figures 1 à 7.The invention is however not limited to being implemented on a plug comprising only the base which is shown in Figures 1 to 7.
[0056] L'invention peut également s'appliquer à des embases réalisées différemment.The invention can also be applied to bases made differently.
[0057] Par exemple, l'invention s'applique également à une embase telle que celle illustrée sur les figures 8 à 11.For example, the invention also applies to a base such as that illustrated in Figures 8 to 11.
[0058] L'opercule 16' d'obturation du puits verseur 50 s'inscrit dans un plan perpendiculaire à l'axe Z, comme illustré notamment en figure 8 et 10.The sealing cap 16 'of the pouring well 50 is in a plane perpendicular to the Z axis, as illustrated in particular in FIGS. 8 and 10.
[0059] L'opercule 16' présente trois disques 80 délimités par un rétrécissement de matière plastique dans l'épaisseur de l'opercule 16'.The lid 16 'has three discs 80 delimited by a plastic narrowing in the thickness of the lid 16'.
[0060] Chacun des disques 80 est lié par une patte 81 à un anneau de préhension 82.
[0061] Du fait du rétrécissement de matière dans l'épaisseur de l'opercule 16', lorsque l'anneau de préhension est tiré, les trois disques 80 se désolidarisent de l'opercule 16', laissant béantes trois ouvertures de diamètre sensiblement plus petit que celui du puits verseur 50.Each of the disks 80 is connected by a tab 81 to a gripping ring 82. Due to the shrinkage of material in the thickness of the lid 16 ', when the gripping ring is pulled, the three discs 80 are disengaged from the lid 16', leaving gaping three openings of diameter substantially more small as that of the pouring pit 50.
[0062] Un tel mode de réalisation est particulièrement avantageux dans le cadre d'une application de l'embase à la délivrance d'un liquide moins visqueux que l'huile alimentaire. Notamment, ce mode de réalisation est particulièrement destiné à la délivrance de vinaigre alimentaire.Such an embodiment is particularly advantageous in the context of an application of the base to the delivery of a liquid less viscous than the edible oil. In particular, this embodiment is particularly intended for the delivery of food vinegar.
[0063] Par ailleurs, et pour faciliter l'ouverture du capot 6, ce dernier comporte sur la face externe de sa jupe 20, diamétralement à l'opposé des moyens 7 de pivotement, une partie striée 36 offrant une prise pour l'utilisateur.Moreover, and to facilitate the opening of the cover 6, the latter comprises on the outer face of its skirt 20, diametrically opposite the means 7 of pivoting, a ridged portion 36 providing a grip for the user .
[0064] On va maintenant . décrire le procédé de montage de l'embase 3 avec le capot 6.We are going now. describe the method of mounting the base 3 with the cover 6.
[0065] L'embase 3 et le capot 6 sont tout d'abord moulés par injection séparément - le capot 6 étant moulé fermé - puis on assemble rigidement entre elles les deux pièces 3 et 6 en suivant les étapes décrites ci-après :The base 3 and the cover 6 are first injection molded separately - the cover 6 being molded closed - then rigidly assembled together the two parts 3 and 6 by following the steps described below:
[0066] L'embase et le capot sont disposés de manière coaxiale.The base and the cover are arranged coaxially.
[0067] On procède à une première étape de rapprochement par translation relative du capot 6 par rapport à l'embase suivant l'axe Z de sorte que la butée 70 pénètre dans le puits verseur 50.We proceed to a first approximation step relative translation of the cover 6 relative to the base along the Z axis so that the stopper 70 enters the pouring well 50.
[0068] On procède à une seconde étape de rotation du capot par rapport à l'embase autour de l'axe Z, en l'espèce dans le sens horaire, jusqu'à ce que la butée 70 entre en contact
avec la contrebutée 71 en saillie de la paroi interne 12 de l'embase, la paroi interne 12 constituant une paroi du puits verseur 50. L'outil qui assure cette rotation est par exemple muni d'un capteur de couple commandant l'arrêt de la rotation lorsque le butée 70 rencontre la contrebutée 71, ou d'un limiteur de couple assurant un débrayage de l'entraînement en rotation. Le cas échéant la première et la deuxième étape peuvent être combinées en une étape de rapprochement par mouvement combinant un translation suivant l'axe Z et une rotation autour de l'axe Z dans le sens d'indexation.A second step of rotation of the cap relative to the base around the Z axis is carried out, in this case in the clockwise direction, until the stop 70 comes into contact. with the abutment 71 projecting from the inner wall 12 of the base, the inner wall 12 constituting a wall of the pouring well 50. The tool which provides this rotation is for example provided with a torque sensor controlling the stopping of the rotation when the stop 70 meets the abutment 71, or a torque limiter ensuring disengagement of the rotational drive. Where appropriate, the first and second stages can be combined in a movement approach step combining translation along the Z axis and rotation around the Z axis in the indexing direction.
[0069] Enfin, on procède à une étape de translation relative sans rotation du capot par rapport à l'embase suivant l'axe Z jusqu'à insertion de l'anneau dans la gorge annulaire et encliquetage du relief d'accrochage 18, ledit anneau s'y trouvant alors maintenu par le relief d'accrochage 18.Finally, we proceed to a relative translation step without rotation of the cover relative to the base along the Z axis until insertion of the ring in the annular groove and latching hooking relief 18, said ring then being maintained by the hooking relief 18.
[0070] Ainsi, l'embase^ et le capot sont solidarisés en étant positionnés de telle manière que le col 32 de l'embase se trouve en regard des moyens de pivotement 7 et des parties vides 28 du capot 6.Thus, the base ^ and the cover are secured by being positioned in such a way that the neck 32 of the base is opposite the pivoting means 7 and the empty parts 28 of the cover 6.
[0071] L'étanchéité du bouchon aux agents polluants est ainsi assurée.
The sealing of the pollutant plug is thus ensured.
