Description

ENSEMBLE DE BOUCHAGE ETANCHE AVEC TUBE VERSEUR ESCAMOTA¬ BLE A ORIENTATION MD TIDIRECTIONNE LE. WATERPROOF CAPPING ASSEMBLY WITH ESCAMOTA¬ BLE TUBE WITH ORIENTATION MD TIDIRECTIONNE LE.
La présente invention concerne un ensemble de bou- chage étanche avec tube verseur escamotable à orientation multidirectionnelle, destiné à être utilisé en coopéra¬ tion avec des récipients, et notamment des bidons conte¬ nant des huiles,des lubrifiants et autres produits simi¬ laires.The present invention relates to a sealed closure assembly with retractable pouring tube with multidirectional orientation, intended to be used in cooperation with containers, and in particular cans containing oils, lubricants and other similar products.
On connait déjà des bidons destinés aux huiles de lubrification, obtenus par la technique dite d'extrusion- soufflage, comportant un bec verseur et une portion en forme de soufflet pour permettre une certaine orienta- tion. Malheureusement, cette technique d'extrusion-souf- flage est délicate à mettre en oeuvre, du fait même que l'on doit décentrer la paraison. Par ailleurs, le souf¬ flet obtenu donne une orientation assez imprécise et limitée, notamment avec des bidons de contenance moyenne (cinq litres et plus). Enfin, le remplissage de ces bi¬ dons, qui sont alors nécessairement équipés du tube ver¬ seur à soufflet, est délicat, difficile et donc onéreux.There are already known cans intended for lubricating oils, obtained by the technique known as extrusion blow molding, comprising a pouring spout and a bellows-shaped portion to allow a certain orientation. Unfortunately, this extrusion-blow molding technique is difficult to implement, because of the fact that the parison has to be decentered. Furthermore, the souf¬ flet obtained gives a rather imprecise and limited orientation, in particular with cans of medium capacity (five liters and more). Finally, filling these bi¬ donations, which are then necessarily equipped with the bellows ver¬ tube, is delicate, difficult and therefore expensive.
On a alors proposé des bidons munis d'un tube ver- seur séparé, destinés à être mis en place sur le col du bidon lors du versement du produit. Ce tube verseur mono¬ lithique qui comporte une embase raccordée à une portion souple en forme de soufflet à effet de mémoire, est des¬ tiné à permettre un versement précis d'un liquide dans n'importe quelle direction. Cette embase présente un filetage complémentaire du filetage extérieur du col du bidon, afin de permettre au tube verseur d'être vissé sur ledit col. Il est à noter que le filetage ménagé à l'ex¬ térieur du col est destiné, classiquement, à permettre la fermeture du bidon au moyen d'un bouchon. Bien que très commode d'utilisation, facile et éco¬ nomique du point de vue réalisation, ce tube verseur présente l'inconvénient de ne pas faire partie intégrante du bidon et ainsi, lorsque celui-ci est fermé, d'être stocké séparément. En outre, en plus des risques de per¬ tes éventuelles du tube, on n'est jamais à l'abri des taches de lubrifiant résiduel sur les parois du tube après utilisation, ou des risques de pénétration de pous¬ sières et autres impuretés dans le bidon, ce qui risque d'encrasser le matériel lubrifié lors du versement du lubrifiant au moyen dudit tube.Canisters were then proposed provided with a separate pouring tube, intended to be placed on the neck of the canister when the product was poured. This mono¬ lithic pouring tube which comprises a base connected to a flexible portion in the form of a bellows with memory effect, is intended to allow precise pouring of a liquid in any direction. This base has a thread complementary to the external thread of the canister neck, in order to allow the pouring tube to be screwed onto said neck. It should be noted that the thread formed outside the neck is intended, conventionally, to allow the closure of the container by means of a plug. Although very convenient to use, easy and economical from the point of view of production, this pouring tube has the drawback of not being an integral part of the container and thus, when the latter is closed, of being stored separately. In addition, in addition to the risks of possible per¬ your tube, it is never safe from residual lubricant stains on the walls of the tube after use, or the risk of penetration of dust and other impurities in the can, which risks clogging the lubricated material during the pouring of the lubricant by means of said tube.
Dans le document US-A-4 560 081, on a proposé un bouchon à couvercle pour boite, associé à une portion de soufflet comprimée par le couvercle. En ouvrant le cou¬ vercle, on libère le soufflet escamoté, qui forme alors tube verseur. Cette solution, adpatée aux boites desti¬ nées à contenir des boissons, n'est pas satisfaisante pour les récipients à col, car elles ne permet pas de faire appel à des soufflets suffisamment longs pour ob¬ tenir une orientation multidirectionnelle.In document US-A-4,560,081, a cover cap for a box has been proposed, associated with a portion of bellows compressed by the cover. By opening the cover, the retracted bellows is released, which then forms a pouring tube. This solution, suitable for boxes intended to contain drinks, is not satisfactory for neck containers, because they do not allow the use of bellows long enough to obtain a multidirectional orientation.
La présente invention pallie ces inconvénients. Elle vise un ensemble de bouchage étanche avec tube verseur escamotable, à orientation multidirectionnelle facile et économique à fabriquer, commode à utiliser et faisant partie du bidon, sans être irrémédiablement solidaire de ce dernier, de façon à bien faciliter le versement précis du contenu du bidon ou le remplissage de ce dernier.The present invention overcomes these drawbacks. It aims for a sealed closure assembly with retractable pouring tube, multidirectional orientation easy and economical to manufacture, convenient to use and forming part of the container, without being permanently attached to the latter, so as to facilitate the precise pouring of the content of the container. or filling it.
Cet ensemble de bouchage étanche avec tube verseur, pour récipient comprenant un col cylindrique, dont la face externe comporte un filetage, constitué par :This sealed closure assembly with pouring tube, for container comprising a cylindrical neck, the external face of which comprises a thread, constituted by:
. un bouchon de fermeture proprement dit présentant une corolle ; . un tube verseur en forme de soufflet à effet de mémoire et à orientation multidirectionnelle, escamotable dans le col et comprimé contre la face intérieure de la corolle du bouchon de fermeture une fois mis en place sur le col, se caractérise en ce qu'il comporte également un élément intermédiaire annulaire en forme de U, définissant deux branches respectivement interne et externe, destinées à enjamber partie essentielle du col : - la face externe de la branche interne épousant partie essentielle de la face interne du col ;. an actual closure cap having a corolla; . a bellows-shaped pouring tube with memory effect and multidirectional orientation, retractable in the neck and compressed against the inner face of the corolla of the closure cap once placed on the neck, is characterized in that it comprises also a U-shaped annular intermediate element, defining two internal and external branches respectively, intended to span the essential part of the neck: - the external face of the internal branch marrying essential part of the internal face of the neck;
- l'extrémité inférieure de la branche interne pré¬ sentant un épaulement contre lequel vient s'appuyer l'ex¬ trémité inférieure du soufflet, dont l'extrémité supé- rieure est comprimée contre la face intérieure de la corolle du bouchon.the lower end of the internal branch having a shoulder against which the lower end of the bellows comes to bear, the upper end of which is pressed against the internal face of the corolla of the plug.
En d'autres termes, la présente invention se carac¬ térise en ce que l'on associe un tube verseur escamotable à orientation multidirectionnelle à un élément intermé¬ diaire de forme adaptée d'une part, au dit tube verseur et d'autre part, au col d'un récipient. De la sorte, le tube verseur est en permanence à l'intérieur du réci¬ pient.In other words, the present invention is characterized in that a retractable pouring tube with multidirectional orientation is associated with an intermediate element of suitable shape on the one hand, with said pouring tube and on the other hand , at the neck of a container. In this way, the pouring tube is permanently inside the container.
De manière connue, un "soufflet" est une portion souple formée par une succession de plis droits disposés en accordéon. Un "soufflet à effet de mémoire" est un soufflet qui peut être étiré et incliné dans une position déterminée sous l'effet d'une première force, et qui, sous l'effet d'uen force inverse, revient sans distorsion sensible à sa position initiale ou dans une autre posi¬ tion. Avantageusement, en pratique :In known manner, a "bellows" is a flexible portion formed by a succession of straight folds arranged in an accordion. A "memory effect bellows" is a bellows which can be stretched and inclined in a determined position under the effect of a first force, and which, under the effect of a reverse force, returns without distortion sensitive to its initial position or in another position. Advantageously, in practice:

- l'extrémité inférieure du soufflet est prolongée par une portion cylindrique qui pénètre dans le réci¬ pient, et dont la face externe disposée au voisinage de l'extrémité présente une saillie et une butée ménageant un espace correspondant à la longueur de l'épaulement disposé à l'extrémité de la branche interne de l'élément intermédiaire, pour encastrer l'extrémité de cette por¬ tion cylindrique sur ledit épaulement ;- The lower end of the bellows is extended by a cylindrical portion which penetrates into the container, and the external face of which is disposed in the vicinity of the end has a projection and a stop providing space corresponding to the length of the shoulder disposed at the end of the internal branch of the intermediate element, to embed the end of this cylindrical por¬ tion on said shoulder;
- l'extrémité inférieure du soufflet est soudée à 1'épaulement ;- The lower end of the bellows is welded to the shoulder;

La figure 3 est une vue en détail de la zone de raccordement entre deux plis droits du soufflet constitu¬ tif du tube verseur.Figure 3 is a detailed view of the connection zone between two straight folds of the bellows constit¬ tive of the pouring tube.
La figure 4 est une vue en coupe d'un mode d'exécu¬ tion préféré de l'invention, montré en détail partiel à la figure 5. FIG. 4 is a sectional view of a preferred embodiment of the invention, shown in partial detail in FIG. 5.
Dans les figures, la référence générale (1) désigne un bidon, dont le col (2) présente, sur sa face externe un filetage (9), et un joint annulaire (29) dont le rôle sera décrit ultérieurement.In the figures, the general reference (1) designates a container, the neck (2) of which has a thread (9) on its external face, and an annular seal (29) whose role will be described later.
Dans une première forme d'exécution, le tube verseur conforme à l'invention, désigné par la référence générale (6) est monolithique et comporte deux portions, respec¬ tivement une portion inférieure cylindrique (7) raccordée à une portion supérieure (8) souple en soufflet à effet de mémoire, permettant ainsi une inclinaison dans toutes les directions, la zone de raccordement entre les deux portions (7) et (8) définissant un épaulement (45), dont le rôle sera également décrit ultérieurement.In a first embodiment, the pouring tube according to the invention, designated by the general reference (6) is monolithic and comprises two portions, respec¬ tively a cylindrical lower portion (7) connected to an upper portion (8) flexible bellows effect memory, allowing an inclination in all directions, the connection area between the two portions (7) and (8) defining a shoulder (45), whose role will also be described later.
Ce tube verseur est avantageusement réalisé par mou¬ lage de matière plastique, tel que du polyéthylène haute densité ou polypropylène, notamment par extrusion-souf- flage.This pouring tube is advantageously produced by molding of plastic material, such as high density polyethylene or polypropylene, in particular by extrusion-blowing.
La portion souple à soufflet (8), se termine sur le haut par une zone annulaire en couronne (10), destinée à coopérer de manière étanche avec une couronne interne (4) ménagée sous la corolle du bouchon de fermeture (3) . L'extrémité supérieure (11) de la zone annulaire en cou¬ ronne (10) est destinée à coopérer avec la face interne de la corolle (51) du bouchon (3) , lorsque le tube ver¬ seur est en position escamotée.The flexible bellows portion (8) ends at the top with an annular zone in a crown (10), intended to cooperate in leaktight manner with an internal crown (4) formed under the corolla of the closure cap (3). The upper end (11) of the ring-shaped annular zone (10) is intended to cooperate with the internal face of the corolla (51) of the plug (3), when the ver¬ sor tube is in the retracted position.
Selon une caractéristique de l'invention, le bouchon de fermeture (3) coopère de manière étanche avec un élé¬ ment intermédiaire caractéristique annulaire en forme de U (14), globalement en forme de couronne cylindrique et dont la majeure partie est disposée à l'intérieur du col (2) du bidon (1). Cet élément intermédiaire caractéristi- que annulaire (14) définit deux branches, respectivement externe (19) et interne (50), et enjambe partie essen¬ tielle du col (2). La face externe de la branche interne (50) épouse partie essentielle (32) de la face interne du col (2). Cet élément intermédiaire (14) est fixé de ma¬ nière réversible ou non au niveau de la zone supérieure (32) du col (2) du bidon (1), et ce, par clipsage au moyen d'un jonc annulaire (20) ménagé sur la face interne du rabat externe en forme de couronne (19) dudit élément intermédiaire (14), coopérant avec un jonc complémentaire (29) situé, sur la face externe de la zone supérieure (32) du col (2) du bidon (1). De fait, lorsque l'élément intermédiaire (14) est clipsé sur le col (2), l'extrémité supérieure (33) dudit col (2) est en butée contre la base de raccordement (21) du rabat (19), maintenant ainsi fermement ledit élément intermédiaire en position opéra¬ tionnelle sur le col (2).According to a characteristic of the invention, the closure cap (3) cooperates in leaktight fashion with a characteristic annular U-shaped intermediate element (14), generally in the form of a cylindrical crown and the major part of which is disposed at the inside the neck (2) of the container (1). This intermediate element characteris- that annular (14) defines two branches, respectively external (19) and internal (50), and spans the essential part of the neck (2). The external face of the internal branch (50) follows essential part (32) of the internal face of the neck (2). This intermediate element (14) is fixed in a reversible manner or not at the upper zone (32) of the neck (2) of the container (1), and this, by clipping by means of an annular ring (20) formed on the internal face of the external flap in the form of a crown (19) of said intermediate element (14), cooperating with a complementary rod (29) located on the external face of the upper zone (32) of the neck (2) of the container (1). In fact, when the intermediate element (14) is clipped onto the neck (2), the upper end (33) of said neck (2) abuts against the connection base (21) of the flap (19), now thus firmly said intermediate element in the operative position on the neck (2).
Ainsi, lorsque l'élément intermédiaire (14) est clipsé sur le col (2), il y a coopération étanche au niveau de la zone référencée (30) entre ledit élément intermédiaire (14) et la zone supérieure (32) dudit colThus, when the intermediate element (14) is clipped onto the neck (2), there is sealed cooperation at the level of the zone referenced (30) between said intermediate element (14) and the upper zone (32) of said neck.
(2).(2).
Comme on peut le voir sur la figure 1, lorsque le tube verseur (6) est en position escamotée, la portion souple à soufflets (8) est comprimée entre la face inter¬ ne (51) de la corolle du bouchon (3) au niveau de l'ex¬ trémité (11) de la dite zone annulaire en couronne (10), et entre 1'épaulement (15) ménagé à cet effet au niveau de la partie intérieure et inférieure dudit élément in¬ termédiaire (14) . Cet épaulement caractéristique (15) coopère avec l'épaulement complémentaire (45) ménagé au niveau de la zone de raccordement des deux portions res- pectivement cylindrique (7) et souple (8) du tube verseur (6). La face interne (34) de l'extrémité dudit épaulement (15) de l'élément intermédiaire (14) présente des joncs annulaires (16) destinés à permettre un coulissage "étan¬ che" de la portion cylindrique (7) du tube verseur (6) , notamment afin de permettre la sortie hors du col (2) dudit tube verseur (6) .As can be seen in FIG. 1, when the pouring tube (6) is in the retracted position, the flexible bellows portion (8) is compressed between the internal face (51) of the corolla of the plug (3) at level of the ex¬ end (11) of said annular ring zone (10), and between the shoulder (15) provided for this purpose at the level of the inner and lower part of said intermediate element (14). This characteristic shoulder (15) cooperates with the complementary shoulder (45) formed at the level of the connection zone of the two respective cylindrical (7) and flexible (8) portions of the pouring tube. (6). The internal face (34) of the end of said shoulder (15) of the intermediate element (14) has annular rods (16) intended to allow sliding "etan¬ che" of the cylindrical portion (7) of the pouring tube (6), in particular to allow the outlet from the neck (2) of said pouring tube (6).
La course du coulissage de la portion cylindrique (7) du tube verseur (6) est limitée au moyen d'une butée dite de maintien (12), destinée à coopérer avec l'extré¬ mité inférieure de l'épaulement (15) de l'élément inter¬ médiaire (14). De plus, et comme on peut le voir sur la figure 2, afin d'éviter un glissement intempestif du tube verseur à l'intérieur du bidon (1) en cours d'utilisa- tion, la portion cylindrique (7) est maintenue en place lorsque le tube verseur est sorti, au moyen d'une saillie (13), jouant le rôle de clipsage, et maintenant 1'épaule¬ ment (15) de l'élément intermédiaire (14) entre cette dite saillie (13) et la butée de maintien (12). De fait, la distance séparant la saillie (13) de la butée de main¬ tien (12) correspond sensiblement, aux tolérances près, à la longueur de la face interne (33) dudit épaulement (15) . De plus, pour permettre la sortie hors du bidon (1) de la totalité de la zone souple à soufflets (8), la distance séparant 1'épaulement (45) de la butée de main¬ tien (12) correspond sensiblement à la longueur de la portion cylindrique de l'élément intermédiaire (14), située à l'intérieur dudit bidon (1).The sliding stroke of the cylindrical portion (7) of the pouring tube (6) is limited by means of a so-called retaining stop (12), intended to cooperate with the lower end of the shoulder (15) of the intermediate element (14). In addition, and as can be seen in FIG. 2, in order to avoid inadvertent sliding of the pouring tube inside the container (1) during use, the cylindrical portion (7) is maintained in place when the pouring tube is pulled out, by means of a projection (13), playing the role of clipping, and now 1'épaule¬ ment (15) of the intermediate element (14) between this said projection (13) and the retaining stop (12). In fact, the distance separating the projection (13) from the main stop (12) corresponds substantially, with tolerances, to the length of the internal face (33) of said shoulder (15). In addition, to allow the outlet from the container (1) of the entire flexible bellows area (8), the distance separating the shoulder (45) from the holding stop (12) corresponds substantially to the length of the cylindrical portion of the intermediate element (14), located inside said container (1).
Selon une autre caractéristique de l'invention, l'extrémité inférieure de la couronne interne (4) située sous la corolle du bouchon (3) , présente des secteurs de clipsage dirigés vers l'extérieur et destinés à coopérer avec un dégagement inférieur situé sous la zone annu- laire en couronne (10) de la portion souple (8) du tube verseur (6) afin de le maintenir comprimé axialement, lorsqu'il n'est pas en position opérationnelle, c'est-à- dire lorsqu'il ne fait pas saillie hors du col (2) du bidon (1) .According to another characteristic of the invention, the lower end of the internal crown (4) located under the corolla of the plug (3), has clipping sectors directed towards the outside and intended to cooperate with a lower clearance located under the annular ring zone (10) of the flexible portion (8) of the tube pourer (6) in order to keep it compressed axially, when it is not in the operational position, that is to say when it does not protrude out of the neck (2) of the container (1).
Selon une autre caractéristique de l'invention, la base de raccordement (21) du rabat (19) de l'élément in¬ termédiaire (14) présente une saillie annulaire (18), dirigée vers 1'extérieur,et destinée à coopérer de maniè- re étanche avec un jonc annulaire (24) ménagé au niveau de la face interne du bouchon (3). De la sorte, le bou¬ chon (3) peut être clipsé sur l'élément intermédiaire (14) indépendamment du bidon (1), c'est à dire sans être vissé sur le filetage (9) du col (2). Lorsque ledit bou- chon (3) est clipsé sur l'élément intermédiaire (14), une couronne annulaire supérieure (17) issue de la base de raccordement (21) du rabat (19) de l'élément intermédiai¬ re (14), est en butée contre un épaulement (35) ménagé au voisinage de la corolle du bouchon (3). De plus, afin d'augmenter l'étanchéité de l'ensemble, ladite couronne annulaire supérieure (17) coopère avec une couronne in¬ terne (22) du bouchon (3), coaxiale et extérieure par rapport à la dite couronne (4), et définissant avec la paroi latérale (23) du bouchon (3) ledit épaulement (35).According to another characteristic of the invention, the connection base (21) of the flap (19) of the intermediate element (14) has an annular projection (18), directed towards the outside, and intended to cooperate tightly sealed with an annular ring (24) formed at the level of the internal face of the plug (3). In this way, the plug (3) can be clipped onto the intermediate element (14) independently of the container (1), that is to say without being screwed onto the thread (9) of the neck (2). When said plug (3) is clipped onto the intermediate element (14), an upper annular ring (17) coming from the connection base (21) of the flap (19) of the intermediate element (14) , is in abutment against a shoulder (35) formed in the vicinity of the corolla of the plug (3). In addition, in order to increase the tightness of the assembly, said upper annular ring (17) cooperates with an internal ring (22) of the plug (3), coaxial and external with respect to said ring (4). , and defining with the side wall (23) of the plug (3) said shoulder (35).
De manière connue, le bouchon (3) présente au ni¬ veau inférieur de sa face interne, un filetage (26) des¬ tiné à coopérer avec le filetage (9) ménagé au niveau du col (2) du bidon (1) .In known manner, the plug (3) has at the lower level of its internal face, a thread (26) des¬ tiné to cooperate with the thread (9) formed at the neck (2) of the container (1).
De manière connue également, l'extrémité inférieure du bouchon (3) présente des secteurs d'accrochage (28) destinés à se clipser au niveau d'un jonc annulaire (27) ménagé à la base du col (2) du bidon (1), afin d'éviter un dévissage intempestif dudit bouchon. En pratique, l'élément intermédiaire (14) caracté¬ ristique et le bouchon (3) sont réalisés par moulage de matière plastique, notamment en polyéthylène basse densi¬ té.In a known manner also, the lower end of the stopper (3) has hooking sectors (28) intended to be clipped at the level of an annular ring (27) formed at the base of the neck (2) of the container (1 ), in order to avoid untimely unscrewing of said plug. In practice, the intermediate element (14) caracté¬ ristique and the plug (3) are made by molding of plastic, in particular in low density polyethylene.
La partie souple à soufflet (8) du tube verseur (6) conforme à l'invention est formée de plis droits élémen¬ taires (36) montrés en détail sur la figure 3. Chacun de ces plis droits est formé par la jonction de deux plans inclinés (38,39,40,41) formant ainsi des zones d'infle¬ xion (42,43,44). L'épaisseur des plis élémentaires au niveau de ces zones d'inflexion est réduite dans chacune des zones de raccordement d'un pli à l'autre.The flexible bellows part (8) of the pouring tube (6) according to the invention is formed of straight folds (36) shown in detail in FIG. 3. Each of these straight folds is formed by the junction of two inclined planes (38,39,40,41) thus forming inflection zones (42,43,44). The thickness of the elementary folds at these inflection zones is reduced in each of the connection zones from one fold to the other.
Ainsi, l'ensemble constitué par le tube verseur escamotable (6), l'élément intermédiaire (14), et le bouchon (3), constitue une entité solidaire par simple clipsage du bouchon (3) sur l'élément intermédiaire (14), comprimant ainsi axialement la portion en soufflet (8) dudit tube (6) entre la corolle du bouchon (3) et l'épau¬ lement (15) de l'extrémité inférieure de l'élément inter¬ médiaire (14). De fait, le remplissage du bidon (1) s'a¬ vère tout à fait aisé.Thus, the assembly constituted by the retractable pouring tube (6), the intermediate element (14), and the plug (3), constitutes an integral entity by simple clipping of the plug (3) on the intermediate element (14). , thus axially compressing the bellows portion (8) of said tube (6) between the corolla of the plug (3) and the shoulder (15) of the lower end of the intermediate element (14). In fact, the filling of the container (1) turns out to be quite easy.
Lorsque l'utilisateur désire verser le contenu du bidon (1), il perce l'opercule, et visse ensuite le bou¬ chon (3) sur le bidon (1) , ledit bouchon étant muni du tube verseur, de l'élément intermédiaire et du bouchon (3) proprement dit. Il visse le bouchon (3) jusqu'à clip- sage de l'élément intermédiaire (14) sur la partie supé¬ rieure (32) du col (2) du bidon (1), et il suffit alors qu'il dévisse le dit bouchon pour libérer le tube verseur (6) . Il oriente alors la portion souple à soufflet (8) dans la direction voulue après avoir tiré celui-ci jus- qu'à clipsage de 1'épaulement (15) entre la saillie (13) et la butée de maintien (12) de la partie inférieure de la portion cylindrique coulissante (7) dudit tube.When the user wishes to pour the contents of the container (1), he pierces the lid, and then screws the cap (3) onto the container (1), said cap being provided with the pouring tube, with the intermediate element. and of the plug (3) proper. It screws the plug (3) until the intermediate element (14) is clipped onto the upper part (32) of the neck (2) of the container (1), and it suffices then that it unscrews the said cap to release the pouring tube (6). It then directs the flexible bellows portion (8) in the desired direction after having pulled it until the shoulder (15) is clipped between the projection (13). and the retaining stop (12) of the lower part of the sliding cylindrical portion (7) of said tube.
Une fois le remplissage terminé, l'utilisteur remet en place le tube verseur à l'intérieur du col par sim¬ ple et légère pression, et recomprime axialement la par¬ tie à soufflet (8) du tube (6) au moyen du bouchon (3). Il revisse alors ce dernier de manière tout à fait clas¬ sique.Once filling is complete, the user puts the pouring tube back inside the neck by simple pressure and lightly, and axially recompresses the bellows part (8) of the tube (6) by means of the plug (3). He then saw the latter again in a completely classic manner.
Comme déjà dit, les figures 4 et 5 montrent un mode de réalisation préféré de l'invention. Ici, le récipientAs already said, Figures 4 and 5 show a preferred embodiment of the invention. Here, the container
(100) comporte un col (101), dont la face interne (102) est sensiblement cylindrique et verticale, et dont la face externe présente un filetage (103).(100) has a neck (101), the internal face (102) of which is substantially cylindrical and vertical, and the external face of which has a thread (103).
La référence (110) désigne un bouchon formé d'une corolle (111) dénommée parfois "plafond" présentant une jupe annulaire d'étanchéité (112), dont l'extrémité (113) présente des secteurs d'accrochage (113) dirigés vers l'extérieur. (114) désigne une jupe annulaire d'appui et de gerbage, et (115) désigne le flanc du bouchon de fer¬ meture (110) dont la face interne présente un filetage (116). Le bas (117) de ce flanc est relié par des ponts sécables non représentés à une ceinture d'inviolabilité (118) réalisée de manière connue. (119) désigne une lan¬ guette également connue permettant de détacher cette ceinture d'inviolabilité (118)'. Selon une caractéristique essentielle de l'invention, l'ensemble de bouchage com- porte un élément intermédiaire annulaire désigné par la référence générale (120), en forme de U définissant deux branches, respectivement interne (121) et externe (122), qui enjambent le col (102). La face externe (123) de la branche interne (121) est sensiblement verticale et cy- lindrique pour épouser la face interne (102) du col (101). L'extrémtié (124) inférieure de cette branche interne (121), présente un épaulement (125) dirigé sur l'intérieur du col (102). La branche externe (122) pré¬ sente, sur sa face interne, un filetage (126) destiné à coopérer avec le filetage (103) du col (102). En revan¬ che, la face externe (127) présente également un filetage destiné à coopérer avec le filetage (116) ménagé sur la face interne du flanc (115) du bouchon de fermeture (110). La portion de raccordement (130) des deux branches (121) et (122) présente, dirigé vers l'extérieur, un jonc circulaire (131) destiné à coopérer avec des secteurs d'accrochage complémentaires (132) ménagés sur la face interne du flanc (115). La référence (135) désigne des crans verticaux ménagés sur le col (102) pour empêcher le retour de la pièce intermédiaire (120). La référence (136) désigne des crans également verticaux, ménagés à la base de la pièce intermédiaire (120) pour empêcher le retour en arrière de la partie intermédiaire (120).The reference (110) designates a plug formed by a corolla (111) sometimes called "ceiling" having an annular sealing skirt (112), the end (113) of which has hooking sectors (113) directed towards outside. (114) designates an annular support and stacking skirt, and (115) designates the side of the closure cap (110), the internal face of which has a thread (116). The bottom (117) of this flank is connected by breakable bridges not shown to a tamper-evident belt (118) produced in a known manner. (119) designates a lan¬ watch also known for detaching this tamper-evident belt (118) '. According to an essential characteristic of the invention, the closure assembly comprises an annular intermediate element designated by the general reference (120), in the shape of a U defining two branches, respectively internal (121) and external (122), which span the neck (102). The external face (123) of the internal branch (121) is substantially vertical and cylindrical to match the internal face (102) of the neck (101). The lower end (124) of this internal branch (121) has a shoulder (125) directed on the inside of the neck (102). The external branch (122) has, on its internal face, a thread (126) intended to cooperate with the thread (103) of the neck (102). In revan¬ che, the outer face (127) also has a thread intended to cooperate with the thread (116) formed on the inner face of the side (115) of the closure plug (110). The connection portion (130) of the two branches (121) and (122) has, directed outwards, a circular rod (131) intended to cooperate with complementary attachment sectors (132) formed on the internal face of the flank (115). The reference (135) designates vertical notches formed on the neck (102) to prevent the return of the intermediate piece (120). The reference (136) designates also vertical notches, formed at the base of the intermediate part (120) to prevent the backward movement of the intermediate part (120).
Le soufflet désigné par la référence générale (140), prend appui à son extrémité (141) sur la face interne (111) de la corolle, et présente un bec verseur (142) qui prend appui sur la jupe annulaire (112). Ce soufflet (140) présente une pluralité de spires, par exemple dix- huit spires comme montré sur le dessin. Selon une carac¬ téristique essentielle de l'invention, l'extrémité in¬ férieure (145) du soufflet (140) prend appui sur l'épau¬ lement (125). Avantageusement, cette extrémité inférieure (145) est soudée sur cet épaulement (125), notamment aux ultra-sons.The bellows designated by the general reference (140), is supported at its end (141) on the internal face (111) of the corolla, and has a pouring spout (142) which is supported on the annular skirt (112). This bellows (140) has a plurality of turns, for example eighteen turns as shown in the drawing. According to an essential characteristic of the invention, the lower end (145) of the bellows (140) bears on the shoulder (125). Advantageously, this lower end (145) is welded to this shoulder (125), in particular with ultrasound.
Après avoir ôté la bague d'inviolabilité (118) et dévissé le bouchon (110), on libère le soufflet (140) que l'on peut commodément tirer vers le haut. Le soufflet (140) est alors en position d'utilisation, et peut donc être orienté dans la direction désirée. Grâce au serrage diamétral de la jupe (112) sur la couronne (142), de la branche (121) de la pièce inter¬ médiaire (120) sur la face interne (102) du col (100), et à la soudure de l'extrémité (145) sur l'épaulement (125), l'ensemble est totalement étanche, notamment aux huiles.After removing the tamper-evident ring (118) and unscrewing the plug (110), the bellows (140) are released which can be conveniently pulled up. The bellows (140) is then in the position of use, and can therefore be oriented in the desired direction. Thanks to the diametrical tightening of the skirt (112) on the crown (142), of the branch (121) of the intermediate piece (120) on the internal face (102) of the neck (100), and to the welding of the end (145) on the shoulder (125), the assembly is completely sealed, in particular to oils.
Le dispositif selon l'invention présente de nombreux avantages par rapport à ceux commercialisés à ce jour.
