Description

La présente invention concerne les dispositifs de bouchage pour flacons, bouteilles et autres récipients à goulot fileté, et plus particulièrement, un élément de bouchage du type dit "capsule" constitué par un capuchon cylindrique fileté intérieurement destiné à être vissé sur le filetage correspondant du goulot du flacon, ledit capuchon étant solidarisé et parfois réalisé en une seule pièce avec une enveloppe ou un enjoliveur externe conférant à la capsule un aspect esthétique.The present invention relates to closure devices for flasks, bottles and other receptacles with a threaded neck, and more particularly, a closure element of the so-called "capsule" type constituted by an internally threaded cylindrical cap intended to be screwed onto the corresponding thread of the neck. of the bottle, said cap being secured and sometimes made in one piece with an envelope or an external cover giving the capsule an aesthetic appearance.

Lorsque de tels éléments de bouchage à enjoliveur externe non cylindrique sont utilisés sur des flacons non cylindriques destinés à recevoir du parfum, des eaux de toilette, des produits de beauté ou similaires, l'aspect esthétique de l'ensemble constitué par l'élément de bouchage et le flacon a une importance primordiale et il est en particulier nécessaire d'obtenir une mise en coincidence parfaite de la section de l'enjoliveur de l'élément de bouchage et de la section du flacon dans la position de blocage en fin de course du capuchon fileté.When such capping elements with non-cylindrical external cover are used on non-cylindrical bottles intended to receive perfume, eau de toilette, cosmetics or the like, the aesthetic appearance of the assembly constituted by the closure and the bottle is of primary importance and it is in particular necessary to obtain a perfect coincidence of the section of the embellishment of the stopper element and of the section of the bottle in the blocking position at the end of travel threaded cap.

On a tout d'abord pensé à résoudre ce problème en orientant convenablement l'enjoliveur externe par rapport au capuchon pour que, dans la position de blocage en fin de course du filet intérieur du capuchon, les sections soient alignées. Pour parvenir plus facilement à réaliser cet alignement lors de la fabrication de l'élément de bouchage, on a proposé de monter la partie enjoliveur de l'élément de bouchage sur le capuchon cylindrique fileté intérieurement en vissant tout d'abord, sur le goulot dudit flacon, le capuchon dont la surface externe est munie de rainures longitudinales, et en emboîtant à force sur ledit capuchon, en lui donnant l'orientation recherchée, ladite partie enjoliveur qui comporte dans ce but un emboîtement interne dont la forme est complémentaire de la surface externe dudit capuchon. Toutefois, après serrages et desserrages répétés de l'élément de bouchage, la position de blocage en fin de course du capuchon intérieur est bien souvent légèrement décalée par suite de l'usure des filets ou du tassement des éléments d'étanchéité et on n'obtient plus dès lors l'orientation correcte de l'élément de bouchage par rapport au corps du flacon ou la position de coincidence n'assure pas un serrage suffisant des joints d'étanchéité.We first thought of solving this problem by properly orienting the external trim relative to the cap so that, in the locking position at the end of travel of the inner thread of the cap, the sections are aligned. To more easily achieve this alignment during the manufacture of the plugging element, it has been proposed to mount the embellishing part of the plugging element on the cylindrical cap internally threaded by first screwing on the neck of said bottle, the cap, the external surface of which is provided with longitudinal grooves, and by forcibly fitting onto said cap, giving it the desired orientation, said embellishing part which, for this purpose, has an internal fitting, the shape of which is complementary to the surface external of said cap. However, after repeated tightening and loosening of the plugging element, the end-of-travel blocking position of the inner cap is very often slightly offset as a result of the wear of the threads or the packing of the sealing elements and there is no more therefore obtains the correct orientation of the closure element relative to the body of the bottle or the coincidence position does not ensure sufficient tightening of the seals.

On a aussi proposé un dispositif dans lequel on utilise un encliquetage par emboîtement de l'enjoliveur sur le corps du flacon au voisinage de la position de blocage en fin de course du capuchon. Dans ce cas l'enjoliveur et le capuchon fileté sont solidaires l'un de l'autre, le bord périphérique de l'enjoliveur formant une lèvre en saillie et la surface supérieure du flacon entourant le goulot portant à sa périphérie une surface d'appui formant gorge dans laquelle la lèvre du bord périphérique de l'enjoliveur doit venir s'emboîter de manière à aligner les sections. Toutefois, pour que cet emboîtement entre surfaces qui ne sont pas de révolution soit possible, le déplacement longitudinal relatif assurant l'emboîtement de la lèvre et de la gorge doit s'effectuer pendant une rotation d'angle très limité correspondant à une fraction d'environ un huitième de tour de l'élément de bouchage qui doit de ce fait présenter un filet à pas très rapide. En outre la paroi du flacon entre la gorge d'emboîtement et le goulot fileté doit être déformable élastiquement puisque la surface supérieure de cette paroi est déjà au contact avec le bord de la lèvre de l'enjoliveur alors que celui-ci doit encore, sous l'effet du vissage du capuchon, descendre de la hauteur de l'emboîtement. Il en résulte que le flacon doit être réalisé en matière plastique, ce qui interdit les flacons en verre ou autre matière rigide tels qu'habituellement employés dans la parfumerie de luxe. En outre, il est certain que les surfaces de contact entre l'enjoliveur et le corps du flacon doivent être planes, ce qui limite les possibilités esthétiques. De plus, avec ce dispositif de bouchage, l'opération de vissage du capuchon est limitée non par l'arrivée en butée de fin de course du capuchon mais par la réalisation de l'emboîtement entre l'enjoliveur et le corps du flacon. Du fait de la rapidité du pas, un faible angle de rotation correspond à un déplacement longitudinal relatif important du capuchon et on risque donc d'avoir un mauvais bouchage par insuffisance de serrage du joint. Enfin l'élasticité et la déformabilité des éléments s'emboîtant ainsi que le couple important résultant du pas rapide du joint qui transforme le serrage élastique des joints en un couple de dévissage, font que les sections de l'enjoliveur et du flacon ne sont jamais parfaitement en coincidence.A device has also been proposed in which a snap-fit engagement of the hubcap is used on the body of the bottle in the vicinity of the end-of-stroke locking position of the cap. In this case the hubcap and the threaded cap are integral with one another, the peripheral edge of the hubcap forming a projecting lip and the upper surface of the bottle surrounding the neck carrying a support surface at its periphery. forming a groove in which the lip of the peripheral edge of the hubcap must fit so as to align the sections. However, so that this fits ment between surfaces which are not of revolution is possible, the relative longitudinal displacement ensuring the interlocking of the lip and the throat must be carried out during a rotation of very limited angle corresponding to a fraction of approximately one eighth of a turn of the plugging element which must therefore have a very fast pitch thread. In addition, the wall of the bottle between the nesting groove and the threaded neck must be elastically deformable since the upper surface of this wall is already in contact with the edge of the lip of the hubcap while the latter must still, under the effect of screwing the cap down from the height of the socket. It follows that the bottle must be made of plastic, which prohibits glass bottles or other rigid material as usually used in luxury perfumery. In addition, it is certain that the contact surfaces between the hubcap and the body of the bottle must be flat, which limits the aesthetic possibilities. In addition, with this closure device, the screwing operation of the cap is limited not by the arrival at the end of the cap end-of-travel but by the achievement of the fitting between the hubcap and the body of the bottle. Because of the rapidity of the pitch, a small angle of rotation corresponds to a significant relative longitudinal displacement of the cap and there is therefore a risk of having a bad blockage due to insufficient tightening of the joint. Finally the elasticity and the deformability of the interlocking elements as well as the significant torque resulting from the rapid pitch of the joint which transforms the elastic tightening of the joints into a loosening torque, means that the sections of the hubcap and of the bottle are never perfectly coincidental.

La présente invention a pour but de remédier aux inconvénients ci-dessus en fournissant un élément de bouchage dont l'enjoliveur est, en position de bouchage, toujours orienté correctement par rapport au corps du flacon.The object of the present invention is to remedy the above drawbacks by providing a closure element whose trim is, in the closure position, always oriented correctly relative to the body of the bottle.

La présente invention aboutit à ce résultat en désolidarisant partiellement au déplacement axial, et éventuellement à la rotation, le capuchon fileté et l'enjoliveur. Par désolidarisation partielle au déplacement axial et à la rotation, on entend une possibilité de variation dans la position longitudinale relative des deux éléments et une possibilité de variation de position angulaire relative entre les deux éléments avec néanmoins, entre ces éléments, une sollicitation élastique, ou une force de frottement associée à un enclenchement mécanique, tendant à maintenir les deux éléments dans une position spatiale relative définie.The present invention achieves this result by partially separating the axial displacement, and possibly rotation, the threaded cap and the hubcap. By partial separation during axial displacement and rotation, is meant a possibility of variation in the relative longitudinal position of the two elements and a possibility of variation of relative angular position between the two elements with, nevertheless, between these elements, an elastic stress, or a friction force associated with a mechanical engagement, tending to maintain the two elements in a defined relative spatial position.

Selon un premier mode de réalisation, le capuchon cylindrique est emboîté dans un manchon axial de l'enjoliveur avec, entre les deux pièces, un encliquetage autorisant entre elles une rotation d'un angle égal à l'angle de symétrie du flacon, l'emboîtement autorisant un déplacement axial relatif égal à la hauteur de l'emboîtement entre l'enjoliveur et le flacon. Par angle de symétrie du flacon, on entend l'angle de rotation qui sépare deux mises en coincidence des sections du flacon et de l'enjoliveur, soit 90° dans le cas d'une section carrée, 180° dans le cas d'une section rectangulaire, 60° dans le cas d'une section hexagonale, etc.According to a first embodiment, the cylindrical cap is fitted into an axial sleeve of the hubcap with, between the two parts, a snap allowing between them a rotation of an angle equal to the angle of symmetry of the bottle, the fitting allowing relative axial movement equal to the height of the fitting between the hubcap and the bottle. By angle of symmetry of the bottle is meant the angle of rotation which separates two coincidences of the sections of the bottle and of the hubcap, that is 90 ° in the case of a square section, 180 ° in the case of a rectangular section, 60 ° in the case of a hexagonal section, etc.

Selon un second mode de réalisation, le,capuchon cylindrique est emboîté dans un manchon axial de l'enjoliveur avec, entre les deux pièces, une liaison d'entraînement autorisant une rotation supplémentaire de l'enjoliveur par rapport au capuchon sous un angle réduit correspondant au jeu dans la position de serrage du capuchon, la liaison d'entraînement autorisant un déplacement axial relatif égal à la hauteur de l'emboîtement entre l'enjoliveur et le flacon. Par angle réduit correspondant au jeu dans la position de serrage du capuchon, on entend l'angle de rotation nécessaire pour amener l'enjoliveur de la position de serrage du capuchon à la position d'emboîtement, c'est-à-dire de coincidence, des sections. La position de blocage du capuchon pouvant varier légèrement d'un angle réduit comme exposé ci-dessus, cette position est fixée de construction pour se trouver en avant de l'une des positions d'enclenchement avec un écart angulaire supérieur à cet angle réduit et la liaison d'entraînement autorise une rotation supplémentaire de l'enjoliveur pour que, le capuchon étant serré, on puisse faire tourner l'enjoliveur pour l'amener en position d'emboîtement. Il est bien évident que l'angle de décalage vers l'avant pourrait être inférieur à la valeur fixée ci-dessus, être nul ou même être négatif sans sortir du cadre de l'invention mais dans un tel cas le capuchon ne serait pas bloqué et le bouchage serait défectueux.According to a second embodiment, the cylindrical cap is fitted into an axial sleeve of the hubcap with, between the two parts, a drive link allowing additional rotation of the hubcap relative to the cap at a reduced angle corresponding to the clearance in the cap tightening position, the drive link allowing a relative axial movement equal to the height of the socket between the hubcap and the bottle. By reduced angle corresponding to the clearance in the tightening position of the cap, is meant the angle of rotation necessary to bring the hubcap from the tightening position of the cap to the nesting position, that is to say coincidence , sections. As the locking position of the cap can vary slightly from a reduced angle as explained above, this position is fixed in construction so as to be in front of one of the engagement positions with an angular difference greater than this reduced angle and the drive link allows additional rotation of the hubcap so that, the cap being tightened, the hubcap can be rotated to bring it into the nesting position. It is obvious that the forward offset angle could be less than the value set above, be zero or even be negative without departing from the scope of the invention, but in such a case the cap would not be blocked. and the plugging would be defective.

Dans l'un et l'autre de ces modes de réalisation un moyen élastique peut être interposé entre le capuchon et l'enjoliveur pour solliciter l'enjoliveur au déplacement longitudinal vers la position d'emboîtement par rapport au capuchon. Ce moyen élastique peut être un ressort de compression, un ressort à lame, une mousse ou une rondelle élastique.In both of these embodiments, an elastic means can be interposed between the cap and the hubcap to urge the hubcap in longitudinal displacement towards the nesting position relative to the cap. This elastic means can be a compression spring, a leaf spring, a foam or an elastic washer.

Selon un troisième mode de réalisation, le capuchon cylindrique formant la partie filetée s/adaptant sur le goulot est solidaire d'un élément formant doublure qui est emboîté dans l'enjoliveur et solidarisé à la rotation par une jupe périphérique avec ledit enjoliveur, au moins la partie de fond de l'élément formant doublure étant réalisée en un matériau flexible.According to a third embodiment, the cylindrical cap forming the threaded part s / adapting to the neck is integral with a liner element which is fitted into the hubcap and secured to rotation by a peripheral skirt with said hubcap, at least the bottom part of the lining element being made of a flexible material.

Dans ce mode de réalisation, le moyen élastique interposé entre le capuchon et l'enjoliveur pour solliciter l'enjoliveur au déplacement longitudinal vers la position d'emboîtement par rapport au capuchon est constitué par la partie de fond flexible dudit élément formant doublure, l'élasticité de cette partie de fond ainsi que la dépression créée entre cette partie de fond et le fond de l'enjoliveur créant la force élastique de sollicitation.In this embodiment, the elastic means interposed between the cap and the hubcap to urge the hubcap in the longitudinal movement towards the nesting position relative to the cap is constituted by the flexible bottom part of said liner element, the elasticity of this bottom part as well as the depression created between this bottom part and the bottom of the hubcap creating the elastic stressing force.

Selon une autre caractéristique de ce mode de réalisation le capuchon fileté est moulé en une seule pièce avec l'élément formant doublure. Dans ce cas et pour éviter tout foirage du filetage du capuchon en matériau flexible, une bague de renfort rigide est engagée autour dudit capuchon.According to another characteristic of this embodiment, the threaded cap is molded in one piece with the lining element. In this case and to avoid any messing of the thread of the cap of flexible material, a rigid reinforcing ring is engaged around said cap.

Dans ce mode de réalisation également et pour assurer la transmission du couple de vissage de l'enjoliveur au capuchon fileté en neutralisant la possibilité de déformation élastique de la chemise périphérique en matériau flexible, ladite chemise périphérique et, éventuellement, la partie périphérique du fond de l'élément de doublage peuvent être collées sur la surface interne de l'enjoliveur, ou une bague rigide et/ou extensible peut appliquer la chemise périphérique contre la face intérieure de l'enjoliveur.In this embodiment also and to ensure the transmission of the screwing torque from the hubcap to the threaded cap by neutralizing the possibility of elastic deformation of the peripheral jacket of flexible material, said peripheral jacket and, possibly, the peripheral part of the bottom of the the lining element can be bonded to the internal surface of the hubcap, or a rigid and / or extensible ring can apply the peripheral jacket against the interior face of the hubcap.

Eventuellement un moyen élastique sollicitant l'enjoliveur à la rotation vers la position d'emboîtement longitudinal par rapport au capuchon peut également être interposé entre le capuchon et l'enjoliveur. Ce moyen élastique peut être combiné avec le moyen élastique sollicitant l'enjoliveur au déplacement longitudinal.Possibly an elastic means urging the hub cap to rotate towards the nesting position longitudinal with respect to the cap can also be interposed between the cap and the hubcap. This elastic means can be combined with the elastic means urging the hub cap in longitudinal displacement.

Pour assurer une orientation parfaite de l'enjoliveur par rapport au flacon dans la position d'emboîtement, nonobstant les tolérances de fabrication des verreries, des surfaces de butée radiales coopérantes peuvent être prévues sur le flacon et l'enjoliveur. L'orientation de l'enjoliveur de l'élément de bouchage au moment de l'emboîtement longitudinal peut être contrôlée par l'emboîtement longitudinal d'au moins une encoche et une dent solidaire l'une de l'enjoliveur et l'autre de la surface supérieure du flacon.To ensure perfect orientation of the hubcap relative to the bottle in the nesting position, notwithstanding the manufacturing tolerances of glassware, cooperating radial abutment surfaces can be provided on the bottle and the hubcap. The orientation of the cover of the plugging element at the time of the longitudinal fitting can be controlled by the longitudinal fitting of at least one notch and a tooth secured to one of the cover and the other of the top surface of the bottle.

Conformément à l'invention et du fait que le capuchon fileté et l'enjoliveur sont désolidarisés partiellement au déplacement axial, la mise en coincidence des surfaces périphériques du moyen de bouchage et du flacon ne s'effectue plus obligatoirement selon une surface radiale plane aboutissant à une ligne de séparation perpendiculaire à l'axe mais peut se faire selon des lignes brisées, dentelées, sinusoidales ou autres. L'invention assure donc, d'une part, un bouchage étanche avec une mise en coincidence parfaite des sections de l'enjoliveur et du flacon et, d'autre part, des possibilités élargies en ce qui concerne les possibilités esthétiques dans le cas d'un flacon à élément de bouchage de ce type.According to the invention and the fact that the threaded cap and the hubcap are partially separated from the axial displacement, the coincidence of the peripheral surfaces of the stopper means and of the bottle no longer necessarily takes place along a flat radial surface leading to a dividing line perpendicular to the axis but can be done in broken, jagged, sinusoidal or other lines. The invention therefore ensures, on the one hand, a tight closure with a perfect coincidence of the sections of the hubcap and the bottle and, on the other hand, enlarged possibilities as regards the aesthetic possibilities in the case of '' a bottle with a closure element of this type.

Bien évidemment le capuchon peut être muni de tout type d'organe d'étanchéité connu coopérant avec le goulot du flacon sans sortir du cadre de la présente invention. Dans le cas où la désolidarisation partielle concerne exclusivement le déplacement axial, une étanchéité du type progressif est préférable par exemple une étanchéité constituée par une jupe tronconique ou cylindrique en matière souple s'emboîtant dans le goulot du flacon, la surface périphérique de cette jupe pouvant comporter des bourrelets en saillie ou une étanchéité assurée par une saillie déformable disposée dans le fond du capuchon concentriquement et à faible distance du manchon fileté du capuchon.Obviously the cap can be provided with any type of known sealing member cooperating with the neck of the bottle without departing from the scope of the present invention. In the case where the partial separation relates exclusively to the axial displacement, a sealing of the progressive type is preferable, for example a seal formed by a frustoconical or cylindrical skirt made of flexible material fitting into the neck of the bottle, the peripheral surface of this skirt being able to include protruding beads or a seal provided by a deformable protrusion arranged in the bottom of the cap concentrically and at a short distance from the threaded sleeve of the cap.

Other characteristics and advantages of the present invention will appear on reading the description given below of various embodiments of a plugging element according to the invention with reference to the attached drawing in which:
  • Figure 1 is an exploded perspective view of a bottle and a closure member according to the present invention; Figure 2 is an axial sectional view of a second embodiment of a closure element according to the present invention adapted to receive a trim of any section; Figure 3 is a sectional view through III-III of Figure 2; Figure 4 is an axial sectional view of a third embodiment of a closure element according to the present invention; Figure 5 is an exploded perspective view of a bottle and a closure element according to a fourth embodiment; Figure 6 is an axial sectional view of the closure element according to the embodiment of Figure 5. 6

En se référant tout d'abord à la figure 1, l'invention s'applique à un flacon 1 ou récipient analogue de section générale rectangulaire qui comporte un goulot fileté 2 sur lequel peut être vissé l'élément de bouchage 4 et dont le col 3 comporte un épaulement 5 venu de matière muni de deux surfaces diamétralement opposées 6 formant butées de positionnement.Referring first to Figure 1, the invention applies to a bottle 1 or similar container of generally rectangular section which has a threaded neck 2 onto which the plugging element 4 can be screwed and the neck 3 of which has a shoulder 5 made of material provided with two diametrically opposed surfaces 6 forming positioning stops.

L'élément de bouchage 4 comporte, conformément à la présente invention, une partie externe qui, dans le mode de réalisation représenté, forme l'enjoliveur du bouchon capsule. Cet enjoliveur de section rectangulaire correspondant à celle du flacon comporte un fond plat 7 entouré par une jupe périphérique 8 et une partie interne constituée principalement par un manchon cylindrique femelle 9 de hauteur inférieure à la hauteur de la jupe formant le capuchon de bouchage proprement dit, dont la partie de base est entourée par un flasque 10 de surface correspondant à la section interne de la jupe 8. Ce capuchon comporte de façon connue un filetage interne susceptible de se visser sur le filetage du goulot 2. D'autre part, la partie supérieure du manchon 9 comporte une entaille 11 dans laquelle est engagé un ressort 12 constitué par une corde à piano dont les deux branches se prolongent de part et d'autre du manchon. Le flasque 10 est de plus muni d'encoches 13 qui permettent l'insertion de la partie interne dans la partie externe, la partie de base de la jupe 8 comportant à cet effet deux bossages en saillie vers l'intérieur 16 diamétralement opposés susceptibles de s'engager dans les encoches 13 de manière à limiter le déplacement vertical de la pièce interne dans la pièce externe. Deux tenons 15 formant des rampes en coin sont positionnés à l'intérieur de la jupe 8, dans des positions diamétralement opposées et près de la partie de fond 7 et ils comportent près de leur partie supérieure des logements 15' destinés à recevoir les extrémités des ailes du ressort 12 comme cela sera exposé ci-après. Enfin le bord libre de la jupe 8 présente des logements 14 de manière à pouvoir s'engager exactement sur le col 3 avec les faces verticales des logements 14 en butée sur les surfaces 6 du col.The closure element 4 comprises, in accordance with the present invention, an external part which, in the embodiment shown, forms the embellishment of the capsule stopper. This cover of rectangular section corresponding to that of the bottle has a flat bottom 7 surrounded by a peripheral skirt 8 and an internal part mainly constituted by a female cylindrical sleeve 9 of height less than the height of the skirt forming the closure cap proper, whose base part is surrounded by a flange 10 of surface corresponding to the internal section of the skirt 8. This cap comprises in known manner an internal thread capable of being screwed onto the thread of the neck 2. On the other hand, the part upper part of the sleeve 9 comprises a notch 11 in which is engaged a spring 12 constituted by a piano cord, the two branches of which extend on either side of the sleeve. The flange 10 is further provided with notches 13 which allow the insertion of the internal part into the external part, the base part of the skirt 8 comprising for this purpose two bosses projecting inwardly 16 diametrically opposite likely to engage in the notches 13 so as to limit the vertical displacement of the internal part in the external part. Two tenons 15 forming corner ramps are positioned inside the skirt 8, in diametrically opposite positions and near the bottom part 7 and they comprise near their upper part housings 15 'intended to receive the ends of the wings of the spring 12 as will be explained below. Finally the free edge of the skirt 8 has housings 14 so as to be able to engage exactly on the neck 3 with the vertical faces of the housings 14 abutting on the surfaces 6 of the neck.

L'élément de bouchage 4 conforme à l'invention est monté en emboîtant à l'aide des encoches 13 et des bossages 16, la pièce interne dans la pièce externe, les extrémités du ressort 12 étant engagées au-dessus des tenons 15 à l'aide d'un outil introduit par les trous 18 du flasque 10 et venant s'insérer dans les logements 15' le ressort étant prétendu de façon à solliciter à l'engagement l'élément interne dans l'enjoliveur externe. Du fait de la forme du flasque 10 et de la jupe 8, l'élément interne ne peut pas tourner à l'intérieur de l'enveloppe, mais est seulement susceptible de se déplacer verticalement, ce déplacement étant limité par les bossages 13-16.The plugging element 4 according to the invention is mounted by fitting together with the notches 13 and the bosses 16, the internal part in the external part, the ends of the spring 12 being engaged above the pins 15 to 1. 'Using a tool inserted through the holes 18 of the flange 10 and coming to be inserted in the housings 15', the spring being pretended so as to urge the internal element into engagement in the external hubcap. Due to the shape of the flange 10 and of the skirt 8, the internal element cannot rotate inside the envelope, but is only capable of moving vertically, this displacement being limited by the bosses 13-16 .

Lors de l'utilisation de l'élément de bouchage celui-ci est vissé sur le goulot 2, le couple étant transmis par l'emboîtement de forme du flasque 10 et de la jupe 8. La partie de base de la jupe 8 vient en butée contre la surface supérieure du col 5 avant que le manchon fileté 9 ne soit entièrement vissé. Toutefois, comme la partie externe peut se déplacer en translation par rapport à la partie interne en bandant encore plus le ressort 12, il est possible d'effectuer une rotation supplémentaire correspondant environ à un demi-tour pour terminer le vissage. A ce moment,la section de l'enjoliveur vient en coincidence avec la section du col du flacon, de sorte que sous l'action du ressort 12, la partie de base de la jupe 8 est amenée à s'enclencher élastiquement sur l'épaulement 5 du col du flacon, les encoches 6 et saillies 14 empêchant par leur mise en butée tout décalage d'orientation entre la section de l'enjoliveur et la section correspondante du flacon. D'autre part pour éviter un désemboitage à force de l'élément de bouchage , on donne au ressort 12 une force suffisante. Lors du débouchage le fonctionnement est inverse, l'opération pouvant être facilitée et le positionnement amélioré en adoucissant l'arête de l'épaulement 5 qui aboutit au bord interne de la surface 6 pour former un plan incliné qui transforme la sollicitation axiale élastique imposée à la jupe 8 par le ressort 12 lors du vissage en un couple sollicitant les faces 14 de la jupe 8 contre les faces de butée 6 du goulot et transformant à l'inverse le couple de dévissage imposé à l'enjoliveur en une force axiale le soulevant en bandant le ressort 12.When using the plugging element, this is screwed onto the neck 2, the torque being transmitted by the form fitting of the flange 10 and the skirt 8. The base part of the skirt 8 comes in abutment against the upper surface of the neck 5 before the threaded sleeve 9 is fully screwed. However, as the external part can move in translation relative to the internal part by further banding the spring 12, it is possible to perform an additional rotation corresponding approximately to a half-turn to complete the screwing. At this time, the section of the hubcap coincides with the section of the neck of the bottle, so that under the action of the spring 12, the base part of the skirt 8 is caused to engage elastically on the shoulder 5 of the neck of the bottle, the notches 6 and projections 14 preventing by their abutment any shift in orientation between the section of the hubcap and the corresponding section of the bottle. On the other hand for avoid forcibly removing the plugging element, the spring 12 is given sufficient force. When uncorking, the operation is reversed, the operation being able to be facilitated and the positioning improved by softening the edge of the shoulder 5 which terminates at the internal edge of the surface 6 to form an inclined plane which transforms the elastic axial stress imposed on the skirt 8 by the spring 12 during screwing in a couple urging the faces 14 of the skirt 8 against the abutment faces 6 of the neck and conversely transforming the unscrewing torque imposed on the hubcap into an axial force lifting it using the spring 12.

Les figures 2 et 3 représentent un autre mode de réalisation de l'élément de bouchage conforme à la présente invention lequel remédie à un certain inconvénient du mode de réalisation de la figure 1 qui exige que l'angle de mise en concordance des sections de l'enjoliveur corresponde exactement à l'angle de blocage du capuchon assurant une étanchéité suffisante. En effet le capuchon et l'enjoliveur ne présentent aucune liberté de rotation relative du fait de l'emboîtement des sections. Plus exactement cette figure comporte un élément standard susceptible d'être solidarisé avec des enveloppes extérieures ou enjoliveurs de modèles divers par encliquetage, soudage ou tout autre procédé. Cet élément est constitué par un manchon cylindrique 20 dont l'extrémité supérieure est fermée par un couvercle 21 pour permettre le montage et dont la partie de base est munie d'une collerette interne 22. Dans ce manchon 20 est inséré un capuchon fileté 22' de type connu qui peut coulis'ser dans l'ouverture de la collerette. L'extrémité supérieure du manchon 22' est munie d'au moins deux saillies radiales 23 susceptibles de coopérer avec des saillies radiales internes 24 prévues à la partie supérieure de la paroi interne du manchon 20, cette disposition ayant pour but de permettre d'entraîner en rotation pour le vissage et le dévissage le capuchon 22' par entraînement du manchon 20. D'autre part, entre la collerette 22 du manchon 20 et le capuchon 22' est inséré un ressort à boudin 25 qui agit comme ressort de compression pour repousser le capuchon 22' contre le couvercle 21 et d'autre part comme ressort de torsion pour solliciter le manchon 20 par rapport au capuchon 22' dans une direction inverse de celle assurant le vissage pour les motifs exposés ci-après. De plus, pour obtenir une meilleure étanchéité, le capuchon interne 22 présente, de manière connue, une saillie tronconique 26 qui s'emboîte dans le goulot du flacon.Figures 2 and 3 show another embodiment of the closure element according to the present invention which overcomes a certain drawback of the embodiment of Figure 1 which requires that the angle of alignment of the sections of the '' hubcap exactly matches the locking angle of the cap ensuring sufficient tightness. Indeed, the cap and the hubcap do not have any relative freedom of rotation due to the interlocking of the sections. More precisely, this figure includes a standard element capable of being secured to external envelopes or embellishments of various models by snap-fastening, welding or any other process. This element consists of a cylindrical sleeve 20 whose upper end is closed by a cover 21 to allow mounting and whose base part is provided with an internal flange 22. In this sleeve 20 is inserted a threaded cap 22 ' of known type which can slide in the opening of the collar. The upper end of the sleeve 22 'is provided with at least two radial projections 23 capable of cooperating with internal radial projections 24 provided at the upper part of the wall internal of the sleeve 20, this arrangement having the aim of making it possible to rotate the cap 22 'for screwing and unscrewing by driving the sleeve 20. On the other hand, between the flange 22 of the sleeve 20 and the cap 22' is inserted a coil spring 25 which acts as a compression spring to push the cap 22 'against the cover 21 and on the other hand as a torsion spring to bias the sleeve 20 relative to the cap 22' in a direction opposite to that ensuring screwing for the reasons set out below. In addition, to obtain a better seal, the internal cap 22 has, in known manner, a frustoconical projection 26 which fits into the neck of the bottle.

Sur le manchon est emboîté un enjoliveur 27 représenté en traits mixtes qui peut avoir une section quelconque y compris une section circulaire, section pour laquelle l'invention est essentielle lorsque, comme représenté, le bord 28 destiné à venir en appui sur le bord supérieur du corps du flacon et ce bord lui-même ne sont pas plan mais présentent un profil denté, ondulé ou autre, ce qui était irréalisable jusqu'ici avec des dispositifs de bouchage du type capsule à enjoliveur.On the sleeve is fitted an embellishment 27 shown in phantom which may have any section including a circular section, section for which the invention is essential when, as shown, the edge 28 intended to come to bear on the upper edge of the body of the bottle and this edge itself is not planar but has a toothed, wavy or other profile, which has hitherto been impracticable with closure devices of the cap type with hubcap.

Pour utiliser le dispositif de bouchage des figures 2 et 3 muni de son enjoliveur on présente comme habituellement le dispositif de bouchage en face du goulot du flacon et le visse. Lorsque le couple de vissage devient important, le ressort 25 se bande à la torsion et les saillies radiales 24 du manchon viennent en butée contre les saillies radiales 23 du capuchon pour assurer l'entraînement en rotation du capuchon jusqu'à serrage complet. Dès qu'un point du bord de la jupe de l'enjoliveur 26 vient en appui au cours de la progression de l'opération contre un point de l'épaulement 5 ou du bord supérieur du flacon, le ressort 25 se comprime pour autoriser le déplacement du capuchon résultant du vissage par rapport au manchon 20 qui se trouve arrêté du fait de cette mise en butée. Lors du blocage du capuchon, l'enjoliveur 27 doit, de par le montage, avoir dépassé légèrement la position de coïncidence des sections de l'enjoliveur et du flacon. Lorsqu'on le libère,le ressort 25 agissant à la torsion tend à ramener l'enjoliveur vers cette position de coincidence, en même temps qu'il agit à la compression pour assurer l'emboîtement. Si la précision de l'emboîtement n'est pas suffisante pour assurer une orientation correcte, on peut prévoir sur l'enjoliveur une surface de butée radiale 29 qui vient buter au cours de la rotation vers l'arrière contre une surface correspondante prévue sur le flacon. Cette butée constitue également un verrouillage contre le débouchage accidentel puisque, pour exercer sur le capuchon un couple de dévissage, il faut d'abord tirer sur l'enjoliveur pour faire échapper la surface 29 à la surface de butée correspondante prévue sur le flacon ou exercer un couple plus élevé si ces surfaces sont des rampes hélicoïdales à pas rapide.To use the closure device of FIGS. 2 and 3 provided with its hubcap, the closure device is presented as usual opposite the neck of the bottle and the screw. When the tightening torque becomes high, the spring 25 is banded at torsion and the radial projections 24 of the sleeve abut against the radial projections 23 of the cap to ensure the rotational driving of the cap until fully tightened. As soon as a point on the edge of the skirt of the hubcap 26 comes to bear during the progress of the operation against a point of the shoulder 5 or of the upper edge of the bottle, the spring 25 is compressed to allow the displacement of the cap resulting from the screwing with respect to the sleeve 20 which is stopped due to this abutment. When the cap is blocked, the hubcap 27 must, by mounting, have slightly exceeded the position of coincidence of the sections of the hubcap and of the bottle. When released, the spring 25 acting on torsion tends to bring the hubcap back to this coincidence position, at the same time as it acts on compression to ensure nesting. If the precision of the fitting is not sufficient to ensure correct orientation, one can provide on the hubcap a radial abutment surface 29 which abuts during the rearward rotation against a corresponding surface provided on the bottle. This stop also constitutes a lock against accidental unblocking since, to exert on the cap a torque of unscrewing, it is first necessary to pull on the hubcap to escape the surface 29 to the corresponding stop surface provided on the bottle or to exercise higher torque if these surfaces are helical ramps with rapid pitch.

On décrira avec référence à la figure 4 un troisième mode de réalisation de l'élément de bouchage conforme à la présente invention. La partie externe de l'élément de bouchage est constituée par une partie de base 30 entourée par une paroi verticale 31 sur laquelle vient se fixer par encliquetage, soudage ou procédé similaire, l'enjoliveur extérieur 32 de l'élément de bouchage. La plaque de base 30 est munie dans sa partie centrale d'une fenêtre circulaire 33 à travers laquelle peut coulisser le capuchon de bouchage. Cette fenêtre 33 est entourée par un manchon 34 faisant saillie vers l'intérieur et destiné à servir d'élément de guidage pour le capuchon de bouchage. Le capuchon de bouchage est constitué comme habituellement par un manchon cylindrique 35 fileté intérieurement de diamètre externe sensiblement égal au diamètre de la fenêtre 33. Le manchon 35 du capuchon est entouré, à une certaine distance de sa partie libre, par un'collet'36 venant prendre appui contre la paroi interne du manchon 34 et destiné à limiter la course du capuchon par rapport à l'enjoliveur. D'autre part, le capuchon 35 comporte dans sa partie supérieure deux perçages 37 diamétralement opposés à travers lesquels passe un ressort à lame 38 dont les deux extrémités sont fixées dans des encoches 39 prévues dans la partie supérieure de la paroi 31. De plus, le manchon 35 du capuchon est fermé de manière connue par une cuvette tronconique 40 formant bouchon destinée à s'emboîter dans le goulot du flacon. Pour assurer une meilleure étanchéité de l'élément de bouchage, la gorge 41 formant raccord entre le manchon 35 et la cuvette 40 est munie d'une lèvre 42 en V auto- jointante qui vient prendre appui contre la partie supérieure du goulot.A third embodiment of the plugging element according to the present invention will be described with reference to FIG. 4. The external part of the plugging element is constituted by a base part 30 surrounded by a vertical wall 31 to which is fixed by snap-fastening, welding or similar process, the external trim 32 of the plugging element. The base plate 30 is provided in its central part with a circular window 33 through which the closure cap can slide. This window 33 is surrounded by a sleeve 34 projecting inwards and intended to serve as a guide element for the closure cap. The closure cap is constituted as usual by a cylindrical sleeve 35 internally threaded with an external diameter substantially equal to the diameter of the window 33. The sleeve 35 of the cap is surrounded, at a certain distance from its free part, by a 'collar' 36 coming to bear against the internal wall of the sleeve 34 and intended to limit the stroke of the cap relative to the hubcap. On the other hand, the cap 35 has in its upper part two diametrically opposite holes 37 through which a leaf spring 38 passes, the two ends of which are fixed in notches 39 provided in the upper part of the wall 31. In addition, the sleeve 35 of the cap is closed in a known manner by a frustoconical cup 40 forming a stopper intended to fit into the neck of the bottle. To ensure better sealing of the plugging element, the groove 41 forming a connection between the sleeve 35 and the bowl 40 is provided with a self-sealing V-shaped lip 42 which bears against the upper part of the neck.

Ce mode de réalisation fonctionne de manière analogue au premier mode de réalisation décrit avec référence à la figure 1 mais il est d'une construction plus simple. Toutefois, le couple de vissage est transmis au capuchon uniquement par le ressort à lame 38 et il peut être avantageux d'assurer une surlargeur aux encoches 39 pour permettre une rotation relative de l'enjoliveur par rapport au capuchon et de prévoir une solidarisation à la rotation en remplaçant le collet 36 par des dents engagées dans des encoches surdimensionnées réalisées dans la surface interne du manchon 34. Avec cette variante de réalisation la mise en coincidence des sections de l'enjoliveur et du flacon est assurée manuellement sauf si elle est assurée par l'enclenchement s'effectuant automatiquement sous l'action du ressort à lame 38 lorsque l'étanchéité du capuchon qui, du fait de la lèvre 42 est atteinte avant blocage mécanique du capuchon est assurée.This embodiment operates in a similar manner to the first embodiment described with reference to Figure 1 but it is of a simpler construction. However, the screwing torque is transmitted to the cap only by the leaf spring 38 and it may be advantageous to provide an extra width at the notches 39 to allow relative rotation of the hubcap relative to the cap and to provide for attachment to the rotation by replacing the collar 36 with teeth engaged in oversized notches made in the internal surface of the sleeve 34. With this variant embodiment the coincidence of the sections of the embellishment and of the bottle is ensured manually unless it is ensured by the engagement taking place automatically under the action of the leaf spring 38 when the sealing of the cap which, due to the lip 42 is reached before mechanical blocking of the cap is ensured.

On décrira maintenant avec référence aux figures 5 et 6, un quatrième mode de réalisation de l'élément de bouchage conforme à la présente invention. L'élément de bouchage s'applique à un flacon 45 ou récipient analogue, de section générale rectangulaire, mais il est sous- entendu que l'élément de bouchage peut aussi s'appliquer à des flacons présentant tout type de section et qu'il est particulièrement adapté pour des sections complexes. Le flacon 45 comporte donc un goulot fileté 46 sur lequel peut être vissé l'élément de bouchage 48 et dont le col 47 comporte un épaulement 49 venue de matière munie de deux surfaces diamétralement opposées 49' formant butées de positionnement.A fourth embodiment of the closure element according to the present invention will now be described with reference to FIGS. 5 and 6. The closure element applies to a bottle 45 or similar container, of generally rectangular section, but it is understood that the closure element can also apply to bottles having any type of section and that it is particularly suitable for complex sections. The bottle 45 therefore comprises a threaded neck 46 onto which the plugging element 48 can be screwed and the neck 47 of which has a shoulder 49 made of material provided with two diametrically opposed surfaces 49 ′ forming positioning stops.

L'élément de bouchage 48 comporte une partie externe qui forme l'enjoliveur du bouchon capsule et une partie interne solidaire du capuchon cylindrique fileté s'adaptant sur le goulot 46. Cet enjoliveur de section rectangulaire correspondant à celle du flacon 45 est réalisé en un matériau rigide et comporte un fond plat 50 entouré par une jupe périphérique 51. D'autre part, le bord libre de la jupe présente intérieurement des logements 51' de manière à pouvoir s'engager exactement sur le col 47 avec les faces verticales des logements 51' en butée sur les surfaces 49' du col. La partie intérieure de l'élément de bouchage est constituée par un élément de doublage de section correspondant à la section interne de l'enjoliveur. L'élément de doublage est constitué d'une partie de fond 52 réalisée en matière flexible telle qu'une matière plastique souple, surface qui est entourée par une jupe 53 de hauteur inférieure à la hauteur de la jupe 51 de l'enjoliveur. Le capuchon cylindrique 54 proprement dit est, dans le mode de réalisation représenté, moulé en une seule pièce avec l'élément formant doublure et il est donc réalisé en la même matière plastique souple que celui-ci. Le capuchon cylindrique 54 est muni sur sa surface interne d'un filetage 55 correspondant au filetage du goulot du flacon 1. D'autre part, une bague cylindrique de renfort en un matériau rigide 56 est engagée autour du capuchon 54 pour éviter tout foirage du pas de vis du capuchon. La jupe 53 de l'élément formant doublure est solidarisée avec la jupe 51 de l'enjoliveur par l'intermédiaire d'une bague 57. Toutefois la solidarisation pourrait être réalisée à l'aide de tous moyens tels que colle ou autre.The closure element 48 comprises an external part which forms the embellishment of the capsule stopper and an internal part integral with the threaded cylindrical cap fitting onto the neck 46. This embellishment of rectangular section corresponding to that of the bottle 45 is produced in a rigid material and has a flat bottom 50 surrounded by a peripheral skirt 51. On the other hand, the free edge of the skirt has internally housings 51 'so as to be able to engage exactly on the neck 47 with the vertical faces of the housings 51 'in abutment on the surfaces 49' of the neck. The inner part of the plugging element is formed by a section doubling element corresponding to the internal section of the hubcap. The lining element consists of a bottom part 52 made of flexible material such as flexible plastic, surface which is surrounded by a skirt 53 of height less than the height of the skirt 51 of the hubcap. The cylindrical cap 54 proper is, in the embodiment shown, molded in one piece with the liner element and it is therefore made of the same flexible plastic material as the latter. The cylindrical cap 54 is provided on its internal surface with a thread 55 corresponding to the thread of the neck of the bottle 1. On the other hand, a cylindrical reinforcement ring made of a rigid material 56 is engaged around the cap 54 to prevent any messing of the no cap screw. The skirt 53 of the lining element is secured to the skirt 51 of the hubcap via a ring 57. However, the fastening could be achieved using any means such as glue or the like.

Lors de l'utilisation de l'élément de bouchage, celui-ci est vissé sur le goulot, le couple étant transmis du fait de la solidarisation de la jupe 53 du bouchon avec la jupe 51 de l'enjoliveur. La partie de base de la jupe 51 vient en butée contre la surface supérieure 49 du col avant que le manchon fileté ne soit entièrement vissé, alors du fait de la déformation élastique de la partie de fond 52 du bouchon et des surfaces latérales du capuchon cylindrique 54, ainsi que de la dépression créée entre cette partie de fond et le fond 50 de l'enjoliveur, on crée la force de sollicitation élastique qui permet d'effectuer un vissage supplémentaire de sorte que la section de l'enjoliveur vienne en coïncidence avec la section du col du flacon. A ce moment, la base de la jupe 51 de l'enjoliveur se verrouille élastiquement sur l'épaulement 49 du col du flacon 45, des encoches 49' et des saillies 51' empêchant par leur mise en butée tout décalage d'orientation entre la section de l'enjoliveur et la section correspondante du flacon.When using the plugging element, it is screwed onto the neck, the torque being transmitted due to the connection of the skirt 53 of the plug with the skirt 51 of the hubcap. The base part of the skirt 51 abuts against the upper surface 49 of the neck before the threaded sleeve is fully screwed, then due to the elastic deformation of the bottom part 52 of the plug and of the lateral surfaces of the cylindrical cap 54, as well as the depression created between this bottom part and the bottom 50 of the hubcap, the elastic biasing force is created which allows additional screwing to be carried out so that the section of the hubcap comes into coincidence with the neck section of the bottle. At this time, the base of the skirt 51 of the hubcap locks elastically on the shoulder 49 of the neck of the bottle 45, of the notches 49 ′ and of the projections 51 ′ preventing by their abutment any shift in orientation between the section of the hubcap and the corresponding section of the bottle.

Les modes de réalisation ci-dessus décrits sont susceptibles de recevoir de nombreuses modifications sans sortir du cadre des revendications ci-après.The embodiments described above are susceptible to numerous modifications without departing from the scope of the claims below.
