The indication element (25) occupies the final position thereof when the cap (2) is returned to the base (1), in such a way as to seal the dispensing hole (11).

Description

Dispositif άf obturation pour ouverture de récipientΆ f closure device for container opening
La présente invention concerne un dispositif d'obturation destiné à être monté sur une ouverture d'un récipient contenant un produit fluide, liquide ou pulvérulent. Ce type de dispositif d'obturation forme ainsi des moyens de distribution du produit fluide contenu dans le récipient. Grâce aux moyens d'obturation intégrés dans le dispositif, la distribution peut être sélectivement permise ou stoppée. Ce genre de dispositif d'obturation peut être utilisé dans de nombreux domaines comme ceux de la cosmétique, de la paracosmétique, des agents de lavage et de nettoyage, des produits alimentaires, de la pharmacie, de la parapharmacie, etc. De manière conventionnelle, le dispositif d'obturation peut comprendre une base définissant des moyens de fixation pour fixer la base sur l'ouverture du récipient. La base définit en général un orifice de distribution de produit fluide par lequel du produit fluide peut être distribué à partir du récipient. D'autre part, le dispositif d'obturation peut comprendre un capuchon amovible destiné à être monté sur la base, ledit capuchon comprenant des moyens d'obturation pour obturer avantageusement de manière étanche l'orifice de distribution de la base. Il s'agit là d'une conception tout à fait classique pour un dispositif d'obturation de l'art antérieur. Le capuchon amovible peut être vissé ou encliqueté sur la base. Le capuchon peut également être articulé de sorte qu'il reste relié à la base, même en position ouverte. Le capuchon, peut par exemple être monté pivotant sur la base entre une position ouverte et une position fermée. Le capuchon peut également être totalement désolidarisé de la base.The present invention relates to a closure device intended to be mounted on an opening of a container containing a fluid, liquid or pulverulent product. This type of closure device thus forms means for distributing the fluid contained in the container. Thanks to the sealing means integrated in the device, the distribution can be selectively enabled or stopped. This kind of closure device can be used in many fields such as cosmetics, paracosmetics, washing and cleaning agents, food products, pharmacy, parapharmacy, etc. Conventionally, the closure device may comprise a base defining fixing means for fixing the base to the opening of the container. The base generally defines a fluid dispensing orifice through which fluid can be dispensed from the container. On the other hand, the closure device can comprise a removable cap intended to be mounted on the base, said cap comprising closure means for advantageously sealingly closing the dispensing orifice of the base. This is a completely conventional design for a shutter device of the prior art. The removable cap can be screwed or snapped onto the base. The cap can also be hinged so that it remains connected to the base, even in the open position. The cap can for example be pivotally mounted on the base between an open position and a closed position. The cap can also be completely detached from the base.
En général, la base est fixée sur l'ouverture du récipient de manière inamovible ou pratiquement inamovible, de telle sorte qu'il n'est pas aisé pour un utilisateur de retirer la base de l'ouverture du récipient. Toutefois, il faut que le capuchon amovible puisse être aisément retiré de la base par l'utilisateur sans utiliser d'autres moyens que ses mains.In general, the base is fixed to the opening of the container in a non-removable or practically non-removable manner, so that it is not easy for a user to remove the base from the opening of the container. However, it is necessary that the removable cap can be easily removed from the base by the user without using other means than his hands.
Un problème est donc d'assurer à l'utilisateur qui vient de se procurer un distributeur équipé d'un tel dispositif d'obturation qu'il est ou sera le premier à retirer le capuchon amovible de la base. En d'autres termes, il faut garantir au premier utilisateur qu'il a la primeur de l'utilisation du distributeur équipé du dispositif d'obturation. Cela permet de rassurer l'utilisateur quant à la nature ou l'origine du produit contenu dans le distributeur. Cela lui garantit également que le récipient est rempli au maximum.A problem is therefore to assure the user who has just obtained a distributor equipped with such a closure device that he is or will be the first to remove the removable cap from the base. In other words, the first user must be guaranteed that he has the first use of the dispenser equipped with the closure device. This reassures the user as to the nature or origin of the product contained in the dispenser. This also ensures that the container is filled to the maximum.
Dans l'art antérieur, on connaît déjà le document US-6 269 986 qui décrit un bouchon de distribution comprenant une base et un capuchon reliés entre eux par un pont d'articulation. La base définit un orifice de distribution obturable par le capuchon. Le capuchon comprend en outre un élément de témoin de premier usage constitué de deux parties reliées entre elles au niveau d'une liaison cassable. La partie reliée au capuchon constitue une partie de pression alors que la partie reliée à la partie de pression constitue une partie d'ancrage. Cette partie d'ancrage comprend en outre une perforation. D'autre part, la base comprend une tête d'ancrage. L'élément de témoin peut être rabattu sur la base lorsque le capuchon est positionné sur la base. En rabattant ainsi l'élément de témoin, l'orifice vient en prise avec la tête d'ancrage. La partie d'ancrage est alors plaquée contre la paroi externe de la base alors que la partie de pression est positionnée au niveau d'un logement. La partie de pression peut être désolidarisée de la partie d'ancrage au niveau de la jonction cassable en faisant pivoter la partie de pression dans le logement. Ainsi, le bouchon de distribution de ce document comprend un système de témoin de premier usage que l'utilisateur doit préalablement actionner en appuyant sur la partie de pression. Avant rupture de la liaison cassable, il n'est pas possible de faire pivoter le capuchon. Le document US-5 875 007 apporte un enseignement similaire. Le document US-3 651 992 décrit un autre type de bouchon à sécurité de premier usage comprenant également une base et un capuchon. Le capuchon est initialement relié de manière monobloc à la base par une articulation. Le capuchon forme un téton d'ancrage engageable dans un logement formé par la base. En basculant le capuchon sur la base, le téton est engagé et bloqué dans le logement. Simultanément, le capuchon et la base coopèrent pour former une charnière. Ensuite, on peut faire pivoter le capuchon autour de la charnière. Pour cela, il faut, lors de la première ouverture du capuchon, casser une liaison au niveau de la base. La rupture de cette liaison donne une indication sur la primeur d'utilisation. Une partie, qui était initialement formée par la base, est séparée de la base et est ensuite solidaire du capuchon. La présente invention a pour but de définir un autre type de moyens de témoin de premier usage qui ne nécessitent pas de manipulation préalable de l'utilisateur. En outre, les moyens de témoin doivent être facilement visibles.In the prior art, document US Pat. No. 6,269,986 is already known, which describes a dispensing cap comprising a base and a cap connected to each other by an articulation bridge. The base defines a dispensing orifice closable by the cap. The cap further comprises a first-use tell-tale element consisting of two parts interconnected at a breakable connection. The part connected to the cap constitutes a pressure part while the part connected to the pressure part constitutes an anchoring part. This anchoring part further comprises a perforation. On the other hand, the base includes an anchor head. The indicator element can be folded down on the base when the cap is positioned on the base. By thus folding the witness element, the orifice engages with the anchoring head. The anchoring part is then pressed against the external wall of the base while the pressure part is positioned at a housing. The pressure part can be detached from the anchoring part at the breakable junction by pivoting the pressure part in the housing. Thus, the dispensing cap of this document includes a first-use indicator system that the user must first activate by pressing on the pressure part. Before breaking the breakable link, it is not possible to rotate the cap. Document US-5 875 007 provides a similar lesson. Document US Pat. No. 3,651,992 describes another type of first-use safety cap also comprising a base and a cap. The cap is initially connected in a single piece to the base by a joint. The cap forms an anchoring stud which can be engaged in a housing formed by the base. By tilting the cap on the base, the stud is engaged and locked in the housing. Simultaneously, the cap and the base cooperate to form a hinge. Then you can rotate the cap around the hinge. For that, it is necessary, during the first opening of the cap, to break a connection at the level of the base. The rupture of this link gives an indication of the first use. A part, which was initially formed by the base, is separated from the base and is then secured to the cap. The object of the present invention is to define another type of first-time control means which do not require prior manipulation by the user. In addition, the witness means must be easily visible.
Pour résoudre ce problème, le dispositif d'obturation selon l'invention comprend des moyens de témoin de premier usage permettant de visualiser aisément un premier retrait du capuchon de la base. Avantageusement, lesdits moyens de témoin comprennent un organe de témoin visuel déplaçable entre une position initiale de garantie de non retrait préalable et une position finale de détection de retrait préalable, ledit organe de témoin déplaçable atteignant sa position finale lorsque le capuchon est remis en place sur sa base de manière à obturer l'orifice de distribution. Grâce à cet organe de témoin visuel, l'utilisateur peut immédiatement s'apercevoir si le dispositif d'obturation a déjà été ouvert ou non. C'est le premier actionnement du capuchon qui va permettre de modifier la position de l'organe de témoin visuel. Ainsi, du premier coup d'œil, l'utilisateur, rien qu'à voir l'orientation de l'organe de témoin visuel, saura si le capuchon a déjà été actionné ou non.To solve this problem, the closure device according to the invention comprises first-time indicator means making it possible to easily visualize a first withdrawal of the cap from the base. Advantageously, said witness means comprise a visual witness member which can be moved between an initial position for guaranteeing no prior withdrawal and a final position for detection of prior withdrawal, said displaceable witness member reaching its final position when the cap is replaced on its base so as to close the dispensing orifice. Thanks to this visual indicator member, the user can immediately perceive whether the shutter device has already been opened or not. It is the first actuation of the cap which will make it possible to modify the position of the visual indicator member. Thus, at first glance, the user, just to see the orientation of the visual indicator member, will know if the cap has already been actuated or not.
Selon une caractéristique avantageuse de l'invention, le déplacement de l'organe de témoin est un déplacement par pivotement. De préférence, la position initiale est séparée de la position finale par une position intermédiaire d'équilibre instable. Ainsi, l'organe de témoin visuel est contraint de se positionner soit en position initiale, soit en position finale en passant par la position intermédiaire d'équilibre instable.According to an advantageous characteristic of the invention, the displacement of the control member is a displacement by pivoting. Preferably, the initial position is separated from the final position by an intermediate position of unstable equilibrium. Thus, the visual witness member is forced to position itself either in the initial position, or in the final position passing through the intermediate position of unstable equilibrium.
Selon une autre caractéristique intéressante de l'invention, l'organe de témoin est sollicité en position finale par un élément d'appui solidaire de la base, ledit organe de témoin étant solidaire du capuchon. Avantageusement, l'organe de témoin s'étend en position initiale, entre la base et l'élément d'appui et, en position finale, entre l'élément d'appui et le capuchon. Selon une forme de réalisation, l'élément d'appui est initialement solidaire du capuchon, et rendu solidaire de la base après montage initial du capuchon sur la base. Avantageusement, l'élément d'appui est initialement solidaire du capuchon par l'intermédiaire de liaisons cassables aptes à être cassées lors du premier retrait du capuchon. De préférence, l'élément d'appui est rendu solidaire de la base par soudage.According to another advantageous characteristic of the invention, the witness member is biased in the final position by a support element integral with the base, said witness member being integral with the cap. Advantageously, the control member extends in the initial position, between the base and the support element and, in the final position, between the support element and the cap. According to one embodiment, the support element is initially secured to the cap, and made integral to the base after initial mounting of the cap on the base. Advantageously, the support element is initially secured to the cap by means of frangible connections capable of being broken during the first removal of the cap. Preferably, the support element is made integral with the base by welding.
Selon une forme de réalisation pratique, l'élément d'appui est formé par un anneau qui s'étend au moins partiellement autour du capuchon, ledit anneau étant initialement relié au capuchon par des ponts de matière cassants, la base comprenant une couronne entourant au moins partiellement l'orifice de distribution, ledit anneau étant fixé, avantageusement par soudage, à la couronne avec une force de fixation supérieure à la force de liaison de l'anneau sur le capuchon, de telle sorte que l'anneau reste fixé à la base lorsque l'on retire le capuchon de la base en cassant les ponts de matière cassants. Avantageusement, la couronne forme un logement destiné à recevoir l'organe de témoin en position initiale. Selon un autre aspect, l'organe de témoin est relié au capuchon le long d'une ligne d'articulation courbe avantageusement définie au niveau d'un bord périphérique inférieur du capuchon. Avantageusement, le capuchon est monté pivotant sur la base. Avantageusement, l'organe de témoin est réalisé en une matière ou une couleur différente du reste du capuchon.According to a practical embodiment, the support element is formed by a ring which extends at least partially around the cap, said ring being initially connected to the cap by bridges of brittle material, the base comprising a crown surrounding at at least partially the dispensing orifice, said ring being fixed, advantageously by welding, to the crown with a fixing force greater than the bonding force of the ring on the cap, so that the ring remains fixed to the base when removing the cap from the base by breaking the bridges of brittle material. Advantageously, the crown forms a housing intended to receive the witness member in the initial position. According to another aspect, the control member is connected to the cap along a curved articulation line advantageously defined at a lower peripheral edge of the cap. Advantageously, the cap is pivotally mounted on the base. Advantageously, the control member is made of a material or a color different from the rest of the cap.
L'anneau formant l'élément d'appui qui est relié d'une part au capuchon par les liaisons cassables et qui est fixé d'autre part à la base avantageusement par soudage forme déjà des moyens de témoin, en ce sens que l'anneau forme un élément de témoin relié initialement, avant le premier retrait du capuchon au capuchon par les liaisons de témoin cassable, et fixé d'autre part à la base, les liaisons cassables étant aptes à être cassées lors du premier retrait du capuchon de sorte que les liaisons cassées informent de l'ouverture préalable du dispositif d'obturation. De ce fait, l'anneau avec ses Uaisons cassables, constituent également des moyens de témoin de premier usage dont la visibilité dépend de la forme, de la configuration et de la taille des liaisons cassables et également de la manière dont elles se cassent. Bien entendu, lorsque les moyens de témoin se présentent sous la forme d'un organe de témoin visuel sollicité par l'anneau soudé entre une position initiale et une position finale, le dispositif d'obturation intègre alors deux moyens de témoin, à savoir l'organe de témoins déplaçable et les liaisons de témoin cassable. Par conséquent, le dispositif d'obturation selon l'invention, peut intégrer des moyens de témoins uniquement sous la forme d'un élément de témoin relié initialement au capuchon par des liaisons de témoin cassables, ou une combinaison d'organe de témoin et d'élément de témoin donnant une double indication quant au premier usage du dispositif d'obturation. On peut également imaginer, que le dispositif d'obturation selon l'invention intègre uniquement des moyens de témoin sous la forme d'un organe de témoin sollicité par un élément d'appui autre qu'un élément de témoin sous la forme d'un anneau relié par des liaisons cassables.The ring forming the support element which is connected on the one hand to the cap by the breakable connections and which is fixed on the other hand to the base advantageously by welding already forms control means, in the sense that the ring forms a witness element initially connected, before the first removal of the cap to the cap by the breakable witness links, and fixed on the other hand to the base, the breakable links being able to be broken during the first removal of the cap so that the broken connections inform of the prior opening of the closure device. Therefore, the ring with its breakable uses, also constitute first-time witness means whose visibility depends on the shape, configuration and size of the breakable links and also on the the way they break. Of course, when the witness means are in the form of a visual witness member urged by the welded ring between an initial position and a final position, the shutter device then integrates two witness means, namely the movable witness body and breakable witness links. Consequently, the shutter device according to the invention can integrate witness means only in the form of a witness element initially connected to the cap by breakable witness links, or a combination of witness member and d 'witness element giving a double indication as to the first use of the shutter device. One can also imagine that the shutter device according to the invention integrates only witness means in the form of a witness member urged by a support element other than a witness element in the form of a ring connected by breakable links.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will now be described more fully with reference to the accompanying drawings which give an embodiment of the invention by way of non-limiting example.
Sur les figures : la figure 1 est une vue en perspective d'une base d'un dispositif d'obturation selon l'invention, les figures 2 et 3 sont des vues en perspective selon des angles différents d'un capuchon, d'un dispositif d'obturation selon l'invention, la figure 4 est une vue en perspective d'un dispositif d'obturation selon l'invention en position initiale avant utilisation, la figure 5 est une vue en perspective du dispositif d'obturation de la figure 4 en position ouverte, et la figure 6 est une autre vue en perspective du dispositif des figures 4 et 5 en position refermée après utilisation.In the figures: FIG. 1 is a perspective view of a base of a closure device according to the invention, FIGS. 2 and 3 are perspective views from different angles of a cap, of a closure device according to the invention, FIG. 4 is a perspective view of a closure device according to the invention in the initial position before use, FIG. 5 is a perspective view of the closure device of FIG. 4 in the open position, and Figure 6 is another perspective view of the device of Figures 4 and 5 in the closed position after use.
Le dispositif d'obturation selon l'invention représenté sur les différentes figures comprend deux éléments constitutifs, à savoir une base 1 et un capuchon 2. Nous verrons ci-après que le dispositif d'obturation comprend encore un anneau 3 qui peut être associé soit au capuchon, soit à la base en terme d'élément constitutif. La base 1 ainsi que le capuchon 2 peuvent être réalisés par injection de matière plastique.The closure device according to the invention shown in the various figures comprises two constituent elements, namely a base 1 and a cap 2. We will see below that the closure device also comprises a ring 3 which can be associated either with the cap, either at the base in constituent element term. The base 1 as well as the cap 2 can be produced by injection of plastic material.
La base 1 peut être réalisée de manière monobloc et est destinée à être montée sur une ouverture d'un récipient (non représenté) contenant un produit fluide, liquide ou pulvérulent. La base 1 comprend des moyens de fixation pour la fixer de manière stable sur l'ouverture du récipient. Ces moyens de fixation peuvent par exemple comprendre une jupe 12 qui est pourvue intérieurement ou extérieurement de moyens d'accrochage destinés à coopérer avec l'ouverture du récipient. De manière classique, la jupe 12 peut être pourvue d'un filetage interne ou d'un profil d'encliquetage interne destiné à coopérer avec une paroi externe du récipient. C'est précisément le cas de la jupe 12 de la base 1 représentée sur les figures. La jupe 12 se prolonge au niveau de son extrémité supérieure par un épaulement rentrant 16 qui s'étend sensiblement sur toute la périphérie de la jupe 12. Au-delà de cet épaulement rentrant 16, la base 1 forme deux contreforts qui définissent ensemble une sorte de couronne 14 qui s'étend partiellement sur la périphérie de la jupe. Les deux contreforts sont séparés par un logement 15 qui forme un évidement dans la couronne 14. De manière diamétralement opposée au logement 15, il est prévu un élément de palier de charnière 13. Entre les deux contreforts formant la couronne 14, et entre le logement 15 et l'élément de pallier de charnière 13, il est prévu une buse centrale 10 percée en son centre par un orifice de distribution 11. Une fois la base 1 montée sur une ouverture de récipient, l'intérieur du récipient peut communiquer avec l'extérieur par l'intermédiaire ou à travers l'orifice de distribution 11. Une zone de la buse 10 entourant l'orifice 11 forme un siège d'étanchéité 110 destiné à coopérer avec un téton d'obturation 210, comme nous le verrons ci-après.The base 1 can be made in one piece and is intended to be mounted on an opening of a container (not shown) containing a fluid, liquid or powdery product. The base 1 comprises fixing means for fixing it stably on the opening of the container. These fixing means may for example comprise a skirt 12 which is provided internally or externally with hooking means intended to cooperate with the opening of the container. Conventionally, the skirt 12 can be provided with an internal thread or an internal latching profile intended to cooperate with an external wall of the container. This is precisely the case of the skirt 12 of the base 1 shown in the figures. The skirt 12 is extended at its upper end by a re-entering shoulder 16 which extends substantially over the entire periphery of the skirt 12. Beyond this re-entering shoulder 16, the base 1 forms two buttresses which together define a kind crown 14 which extends partially over the periphery of the skirt. The two buttresses are separated by a housing 15 which forms a recess in the crown 14. In a diametrically opposite manner to the housing 15, there is provided a hinge bearing element 13. Between the two buttresses forming the crown 14, and between the housing 15 and the hinge bearing element 13, there is provided a central nozzle 10 pierced in its center by a dispensing orifice 11. Once the base 1 is mounted on a container opening, the interior of the container can communicate with the outside via or through the dispensing orifice 11. A zone of the nozzle 10 surrounding the orifice 11 forms a sealing seat 110 intended to cooperate with a closure stud 210, as we will see below -after.
En se référant maintenant aux figures 2 et 3, on peut voir un capuchon 2 qui est destiné à être monté de manière amovible sur la base 1 de manière à obturer de manière étanche l'orifice de distribution 11. Pour ce faire, le capuchon 2 forme un téton d'obturation 210 comme on peut le voir sur la figure 5. La capuchon 2 présente une forme générale de godet comprenant un fond 21 au niveau duquel est formé le téton d'obturation 210. Etant donné que le godet est renverse de manière à former une sorte de coiffe 20, le fond 21 constitue la paroi supérieure du capuchon 2. A partir de cette paroi supérieure 21, la coiffe 20 forme une paroi latérale 22 qui est ici de forme générale tronconique. Selon l'invention, cette paroi latérale 22 est percée d'une fenêtre 220 qui présente un bord supérieur de préhension 211 formé par la paroi supérieure 21. La taille de la fenêtre 220 est telle qu'il est possible d'y pénétrer au moins partiellement un doigt d'une main. On peut ainsi se saisir de la coiffe 20 du capuchon 2 à l'aide d'un doigt d'une main. La paroi latérale 22 définit un bord d'extrémité inférieure libre 201. Un élément d'axe de charnière 24 se raccorde à la coiffe 20 au niveau de ce bord d'extrémité libre 201. De manière diamétralement opposée à l'élément d'axe de charnière 24, le capuchon forme une languette 25 qui est reliée au bord 201 le long d'une ligne d'articulation courbe 205. Nous verrons ci- après de quelle manière cette languette 25 est déplaçable entre deux positions stables. Cette languette peut être réalisée de manière monobloc avec la coiffe 20, dans une matière plastique appropriée. En variante, la languette peut être réalisée en une matière plastique ou une couleur différente de celle de la coiffe, par exemple au moyen d'une technique par bi-injection ou co-moulage.Referring now to Figures 2 and 3, one can see a cap 2 which is intended to be removably mounted on the base 1 so as to seal the dispensing orifice 11 in a sealed manner. To do this, the cap 2 forms a sealing stud 210 as can be seen in FIG. 5. The cap 2 has a general shape of a cup comprising a bottom 21 at the level of which the closing stud 210 is formed. Since the cup is overturns so as to form a sort of cap 20, the bottom 21 constitutes the upper wall of the cap 2. From this upper wall 21, the cap 20 forms a side wall 22 which is here of generally frustoconical shape. According to the invention, this side wall 22 is pierced with a window 220 which has an upper gripping edge 211 formed by the upper wall 21. The size of the window 220 is such that it is possible to penetrate therein at least partially a finger of one hand. It is thus possible to take hold of the cap 20 of the cap 2 using a finger of one hand. The side wall 22 defines a free lower end edge 201. A hinge pin element 24 is connected to the cap 20 at this free end edge 201. Diametrically opposite the axis element hinge 24, the cap forms a tongue 25 which is connected to the edge 201 along a curved articulation line 205. We will see below how this tongue 25 is movable between two stable positions. This tongue can be made in one piece with the cap 20, in a suitable plastic material. Alternatively, the tongue may be made of a plastic material or a color different from that of the cap, for example by means of a technique by bi-injection or co-molding.
En utilisation, c'est-à-dire après la première ouverture du capuchon, celui- ci est constitué de la coiffe 20, de son élément d'axe de charnière 24 et de sa languette déplaçable 25. Cependant, avant la première utilisation, c'est-à-dire avant le premier retrait du capuchon de la base, le capuchon 2 comprend également un anneau 3 qui s'étend au moins partiellement autour de la coiffe 20, et plus précisément au niveau de son bord d'extrémité inférieure 201. Cet anneau 3 s'étend sur toute la périphérie de la coiffe 20 sauf au niveau de l'élément d'axe de charnière 24. L'anneau 3 s'étend également au niveau de la languette déplaçable 25. Cette languette 25 qui est située de manière diamétralement opposée à l'élément d'axe de charnière 24 et avantageusement juste en dessous de la fenêtre de préhension 220, s'étend en position initiale, c'est-à-dire avant montage du capuchon 2 sur la base 1 en dessous de l'anneau 3 comme on peut le voir clairement sur la figure 3. L'anneau 3 présente un amincissement au niveau de la languette 25 sous la forme d'un évidemment interne 33. Cette partie amincie de l'anneau 3 forme un élément d'appui 32 pour la languette 25 comme on le verra ci-après. Cet élément d'appui 32 est avantageusement pourvu d'un appendice de butée et de protection 320 qui s'étend sur une partie de la périphérie externe de l'élément d'appui 32. Cet appendice de protection 320 s'étend vers le bas sensiblement dans la même direction générale que la languette 25. Selon l'invention, l'anneau 3 est relié au restant du capuchon 2 et plus particulièrement à la coiffe 20 au niveau de son bord d'extrémité inférieur 201 par l'intermédiaire de plusieurs liaisons cassantes ou cassables 30. On peut par exemple prévoir six liaisons cassables 30 qui se présentent sous la forme de ponts de matière reliant la coiffe 20 à l'anneau 3, ou plus précisément la périphérie externe de la coiffe 20 au niveau du bord inférieur 201 à la périphérie interne de l'anneau 3.In use, that is to say after the first opening of the cap, the latter consists of the cap 20, its hinge pin element 24 and its movable tongue 25. However, before the first use, that is to say before the first removal of the cap from the base, the cap 2 also comprises a ring 3 which extends at least partially around the cap 20, and more precisely at its lower end edge 201. This ring 3 extends over the entire periphery of the cap 20 except at the level of the hinge pin element 24. The ring 3 also extends at the level of the displaceable tongue 25. This tongue 25 which is located diametrically opposite the hinge pin element 24 and advantageously just below the gripping window 220, extends in the initial position, that is to say before mounting the cap 2 on the base 1 below the ring 3 as can be clearly seen on Figure 3. Ring 3 shows a thinning at the level of the tongue 25 in the form of an internal recess 33. This thinned part of the ring 3 forms a support element 32 for the tongue 25 as will be seen below. This support element 32 is advantageously provided with a stop and protection appendage 320 which extends over part of the external periphery of the support element 32. This protection appendage 320 extends downwards substantially in the same general direction as the tongue 25. According to the invention, the ring 3 is connected to the remainder of the cap 2 and more particularly to the cap 20 at its lower end edge 201 by means of several brittle or breakable connections 30. One can for example provide six breakable connections 30 which are in the form of bridges of material connecting the cap 20 to the ring 3, or more precisely the outer periphery of the cap 20 at the lower edge 201 at the internal periphery of the ring 3.
Le capuchon 2 avec son anneau 3 peut être réalisé de manière monobloc par injection de plastique moulé. Ainsi, la coiffe 20 et l'anneau 3 forment initialement une pièce unitaire monobloc. Cette pièce monobloc 2 peut être montée sur la base 1 telle que représentée sur les figures 2 et 3. Le capuchon 2 est engagé sur la base 1 de manière à ce que le téton d'obturation 210 vienne se loger dans l'orifice de distribution 11 en créant une étanchéité au niveau du siège 110. En outre, l'élément d'axe de charnière 24 vient en prise avec l'élément de palier de charnière 13 formé par la base 1. L'engagement de l'élément d'axe 24 sur l'élément de palier 13 est tel que le capuchon 2 pourra ensuite se déplacer par rapport à la base 1 avec un mouvement de rotation par pivotement autour de l'axe formé par l'association des éléments 13 et 24. De même, l'anneau 3 formé initialement de manière monobloc par le capuchon 2 vient en contact avec la couronne 14 de la base 1. Dans cette configuration représentée sur la figure 4, la languette 25 est positionnée sous l'élément d'appui 32 formé par l'anneau 3, mais également dans le logement 15 formé au niveau de la couronne 14. Le montage du capuchon 2 sur la base 1 pour parvenir à la configuration de la figure 4 s'effectue très simplement sans qu'il soit nécessaire de veiller au positionnement de la languette 25 pour qu'elle vienne se loger dans le logement 15 en dessous de l'élément d'appui 32. En effet, la languette 25 n'a pas changé de position depuis sa fabrication.The cap 2 with its ring 3 can be made in one piece by injection of molded plastic. Thus, the cap 20 and the ring 3 initially form a unitary unitary piece. This one-piece piece 2 can be mounted on the base 1 as shown in FIGS. 2 and 3. The cap 2 is engaged on the base 1 so that the closure stud 210 comes to be housed in the dispensing orifice. 11 by creating a seal at the seat 110. In addition, the hinge pin element 24 engages with the hinge bearing element 13 formed by the base 1. The engagement of the element axis 24 on the bearing element 13 is such that the cap 2 can then move relative to the base 1 with a rotational movement by pivoting around the axis formed by the association of the elements 13 and 24. Similarly , the ring 3 formed initially in a single piece by the cap 2 comes into contact with the crown 14 of the base 1. In this configuration shown in FIG. 4, the tongue 25 is positioned under the support element 32 formed by the ring 3, but also in the housing 15 formed on level water from the crown 14. The mounting of the cap 2 on the base 1 to achieve the configuration of FIG. 4 is carried out very simply without it being necessary to take care of the positioning of the tongue 25 so that it comes to be housed in the accommodation 15 below the support element 32. Indeed, the tongue 25 has not changed position since its manufacture.
Selon l'invention, l'anneau 3 est fixé à la base 1 une fois le capuchon 2 monté sur la base 1. Cette fixation peut s'effectuer par tout moyen technique, mais de préférence, l'anneau 3 est soudé à la base 1 au niveau de la couronne 14.According to the invention, the ring 3 is fixed to the base 1 once the cap 2 is mounted on the base 1. This fixing can be carried out by any technical means, but preferably, the ring 3 is welded to the base 1 at crown 14.
Le soudage peut s'effectuer avec n'importe quelle technique connue, comme par exemple un soudage par ultrason. Ainsi, le capuchon 2 est fixé en position sur la base 1 par l'intermédiaire de l'anneau 3 fixé à la base 1 et relié à la coiffe 20 par l'intermédiaire des liaisons cassables 30. En saisissant la coiffe 20 au niveau de sa fenêtre de préhension 220, et en maintenant la base 1 ou le récipient sur lequel elle est fixée, on peut exercer une force de traction sur la coiffe 20 qui est suffisante pour faire céder ou casser les liaisons cassables 30 qui reUent la coiffe à l'anneau 3. Bien entendu, pour parvenir à la rupture des liaisons 30, il est nécessaire que la force de fixation qui relie l'anneau à la base 1 est supérieure à la force de rupture des liaisons 30. On peut ainsi désolidariser la coiffe 20 de l'anneau 30 de sorte que le capuchon se résume alors simplement à la coiffe 20 pourvue de son élément d'axe de charnière 24 et de sa languette déplaçable 25. Ainsi, l'anneau 3 et plus particulièrement ses liaisons cassantes 30, constituent des moyens de témoin de premier usage sous la forme d'un organe de témoin visuel au niveau desquels on peut aisément et rapidement s'apercevoir si le capuchon a déjà été retiré de la base ou non. En effet, les liaisons cassables 30 n'ont pas la même configuration ou aspect avant et après leur rupture de sorte que l'utilisateur peut aisément voir si les liaisons sont encore intactes ou rompues. Ceci lui donne une information claire sur l'utilisation préalable du dispositif d'obturation.Welding can be carried out with any known technique, such as for example ultrasonic welding. Thus, the cap 2 is fixed in position on the base 1 by means of the ring 3 fixed to the base 1 and connected to the cap 20 by means of the breakable connections 30. By grasping the cap 20 at the level of its gripping window 220, and by maintaining the base 1 or the container on which it is fixed, a tensile force can be exerted on the cap 20 which is sufficient to cause the breakable links 30 which receive the cap to break or break 'ring 3. Of course, to achieve the rupture of the links 30, it is necessary that the fixing force which connects the ring to the base 1 is greater than the breaking force of the links 30. It is thus possible to separate the cap 20 of the ring 30 so that the cap then simply boils down to the cap 20 provided with its hinge pin element 24 and its displaceable tongue 25. Thus, the ring 3 and more particularly its brittle connections 30, constitute means of witness d e first use in the form of a visual indicator member at which one can easily and quickly see if the cap has already been removed from the base or not. Indeed, the breakable links 30 do not have the same configuration or appearance before and after their rupture so that the user can easily see if the links are still intact or broken. This gives him clear information on the prior use of the shutter device.
L'esprit de cette caractéristique protégeable en soi réside dans le fait que l'anneau 3 qui forme les moyens de témoin de premier usage est réalisé ensemble avec le capuchon 2 puis ensuite rapporté et fixé avantageusement par soudage à la base 1. Ensuite, le retrait du capuchon 2 de la base 1 laisse l'anneau 3 fixé à la base 1. Le capuchon 2 n'a même pas besoin d'être pourvu d'une languette 25. Cependant, cette languette déplaçable 25 fait également office de moyen de témoin visuel en coopération avec l'élément d'appui 32 formé par l'anneau 3. En position initiale, la languette 25 s'étend sous l'élément d'appui 32 à l'intérieur du logement 15, comme on peut le voir très clairement sur la figure 4. Lorsque l'on retire le capuchon 2 de la base 1 en rompant les liaisons 30, la languette 25 reliée à la coiffe 20 par la ligne d'articulation 205 est alors extraite du logement 15 et d'en dessous de l'élément d'appui 32. On parvient alors à la configuration ouverte de la figure 5. La coiffe 20 est alors pivotée dans son état d'ouverture maximale de manière à dégager très largement l'orifice de distribution 11. On peut alors procéder à une distribution de produit fluide contenu dans le récipient.The spirit of this characteristic, which can be protected in itself, resides in the fact that the ring 3 which forms the first-use indicator means is produced together with the cap 2 and then added and advantageously fixed by welding to the base 1. Next, the removing the cap 2 from the base 1 leaves the ring 3 fixed to the base 1. The cap 2 does not even need to be provided with a tongue 25. However, this movable tongue 25 also acts as a visual indicator means in cooperation with the support element 32 formed by the ring 3. In the initial position, the tongue 25 extends under the support element 32 to inside the housing 15, as can be seen very clearly in FIG. 4. When the cap 2 is removed from the base 1 by breaking the links 30, the tongue 25 connected to the cap 20 by the line of articulation 205 is then extracted from the housing 15 and from below the support element 32. We then arrive at the open configuration of FIG. 5. The cover 20 is then pivoted in its maximum opening state so as to very clear the dispensing orifice 11. It is then possible to dispense the fluid contained in the container.
Une fois la distribution terminée, l'utilisateur va à nouveau faire pivoter la coiffe 20 pour la ramener dans la position initiale d'obturation étanche de l'orifice de distribution 11. Cependant, la languette 25 qui n'avait jusque là pas encore changée d'orientation depuis sa fabrication, va alors être contrainte de modifier son orientation par un déplacement de pivotement autour de la ligne d'articulation 205. En effet, lors du retrait de la coiffe 20, la languette 25 pour se désengager du logement 15 est venue en contact de l'élément d'appui 32 et a subi une légère déformation par flexion. Immédiatement après avoir quitté le contact avec l'élément d'appui 32, la languette 25 s'est à nouveau détendue pour regagner sa position initiale de repos, qui est indicative d'un non retrait préalable de la coiffe 20. Lors de la remise en place de la coiffe 20 base 1, la languette 25, qui est encore toujours dans sa position initiale, va à nouveau revenir en contact de l'élément d'appui 32, mais cette fois-ci par le dessus, alors que lors du retrait de la languette, celle-ci était venue en contact de l'élément d'appui 24 par le dessous. De ce fait, la languette 25 va être contrainte de pivoter autour de sa ligne d'articulation 205 pour parvenir à une seconde position finale dans laquelle la languette 25 est alors positionnée au-dessus de l'élément d'appui 32 et non plus en dessous comme c'était le cas dans la position initiale de la figure 4. La languette 25 s'étend alors dans une direction faisant un angle de près de 90° par rapport à sa position initiale. Elle pointe alors légèrement vers le haut, tandis qu'en position initiale, elle pointe significativement vers le bas. Ainsi, cette languette déplaçable 25 remplit une fonction de témoin visuel de premier usage, étant donné que l'utilisateur peut immédiatement remarquer si la languette 25 est positionnée au dessus ou en dessous de l'anneau 3. Une position au dessus de l'anneau 3 l'informe clairement d'une utilisation préalable du dispositif d' obturation .Once the dispensing is complete, the user will again pivot the cap 20 to bring it back to the initial sealed closure position of the dispensing orifice 11. However, the tab 25 which had hitherto not changed orientation since its manufacture, will then be forced to modify its orientation by a pivoting movement around the hinge line 205. In fact, when removing the cap 20, the tongue 25 to disengage from the housing 15 is came into contact with the support element 32 and underwent a slight deformation by bending. Immediately after having left the contact with the support element 32, the tongue 25 is again relaxed to return to its initial rest position, which is indicative of a prior withdrawal of the cover 20. When handing over in place of the cap 20 base 1, the tongue 25, which is still still in its initial position, will again come into contact with the support element 32, but this time from above, while during the withdrawal of the tongue, the latter had come into contact with the support element 24 from below. Therefore, the tongue 25 will be forced to pivot around its articulation line 205 to reach a second final position in which the tongue 25 is then positioned above the support element 32 and no longer in below as was the case in the initial position of Figure 4. The tongue 25 then extends in a direction making an angle of nearly 90 ° relative to its initial position. It then points slightly upwards, while in the initial position, it points significantly downwards. Thus, this movable tongue 25 fulfills a function of first-time visual indicator, since the user can immediately notice whether the tongue 25 is positioned above or below the ring 3. A position above the ring 3 clearly informs him of a prior use of the shutter device.
Pour empêcher la languette 25 de pivoter librement lorsque le dispositif d'obturation est ouvert, comme représenté sur la figure 5, la position initiale et la position finale sont des positions stables séparées par une position intermédiaire instable. Ceci est possible du fait que la ligne d'articulation 215 n'est pas rectiligne, mais au contraire courbe, ce qui induit cette position intermédiaire d'équilibre instable séparant les deux positions stables initiale et finale. On assure ainsi que la languette 25 ne peut pas quitter sa position initiale trop facilement, et que son changement d'orientation pour parvenir à la position finale ne peut pratiquement être sollicité que par l'élément d'appui 32. Dans le mode de réalisation représenté sur les figures, le capuchon est relié à la base au moyen d'un système de charnière 12, 24. Le capuchon et la base sont réalisés de manière séparée, en principe par moulage, puis le capuchon est monté sur la base. En variante, le capuchon et la base peuvent être réalisés de manière monobloc en étant reliés l'un à l'autre par un pont de matière qui servira ensuite de charnière ou d'articulation.To prevent the tongue 25 from pivoting freely when the closure device is open, as shown in FIG. 5, the initial position and the final position are stable positions separated by an unstable intermediate position. This is possible due to the fact that the articulation line 215 is not rectilinear, but on the contrary curved, which induces this intermediate position of unstable equilibrium separating the two stable initial and final positions. It is thus ensured that the tongue 25 cannot leave its initial position too easily, and that its change of orientation to reach the final position can practically be requested only by the support element 32. In the embodiment shown in the figures, the cap is connected to the base by means of a hinge system 12, 24. The cap and the base are produced separately, in principle by molding, then the cap is mounted on the base. Alternatively, the cap and the base can be made in one piece by being connected to each other by a bridge of material which will then serve as a hinge or articulation.
Grâce à l'invention, on obtient un dispositif d'obturation mettant en œuvre un ou deux types de moyen de témoin visuel de premier usage tout en limitant le nombre de pièces constitutives à deux. Thanks to the invention, a shutter device is obtained using one or two types of first-time visual indicator means while limiting the number of component parts to two.
