Abstract

The container has a cap fixed in a tank by engagement of a pad (44) in an annular groove (24), where pad and groove are respectively formed on the cap and tank, and vice-versa. Radial blades (45) limit axial and transversal movements between the pad and groove, when the pad is in engagement with the groove. The groove extends in a plane perpendicular to a longitudinal axis of the tank.

Description

La présente invention concerne un récipient comportant un réservoir et un capot destiné à être fixé sur le réservoir par l'engagement d'un bourrelet dans une gorge.The present invention relates to a container comprising a reservoir and a cover intended to be fixed on the tank by the engagement of a bead in a throat.

Dans ce type de récipient, les tolérances de fabrication sont telles que la forme et/ou les dimensions de la gorge ainsi que celles du bourrelet peuvent légèrement varier, ce qui peut entraíner un jeu axial et/ou latéral entre le capot et le réservoir. En outre, même en utilisant toujours le même moule pour la fabrication du capot et le même moule pour la fabrication du réservoir, le jeu qui peut exister entre les capots et les réservoirs obtenus n'est pas toujours identique d'un récipient à l'autre étant donné que chaque moule comporte plusieurs empreintes et que les capots issus d'une empreinte donnée ne sont pas toujours associés aux réservoirs issus d'une même empreinte. Le nombre important d'empreintes entraíne donc un nombre de combinaisons réservoir-capot relativement important et donc un nombre important de jeux différents.In this type of container, the manufacturing tolerances are such that the shape and / or the dimensions of the groove as well as those of the bead can vary slightly, which can cause axial and / or lateral play between the cover and the tank. In addition, even if the same mold is always used for the manufacture of the cover and the same mold for the manufacture of the tank, the game which may exist between the hoods and the tanks obtained is not always identical from one container to another since each mold has multiple imprints and that the covers from a given imprint are not not always associated with tanks from the same footprint. The number large footprints therefore leads to a number of tank-hood combinations relatively large and therefore a large number of different games.

Aussi, est-ce un des objets de l'invention que de réaliser un récipient dans lequel le capot peut se fixer sur le réservoir en évitant que le capot puisse bouger axialement et/ou latéralement lorsqu'il est fixé sur le réservoir, et cela, quel que soit le jeu existant entre le bourrelet et la gorge.It is therefore one of the objects of the invention to produce a container in which the cover can be fixed on the tank avoiding that the cover can move axially and / or laterally when it is fixed on the tank, and this, whatever the clearance between the bead and the groove.

C'est encore un autre objet de l'invention que de réaliser un tel récipient à moindre coût de fabrication.It is yet another object of the invention to produce such a container for lower manufacturing cost.

Selon l'invention, ces objets sont atteints en réalisant un récipient comportant une partie formant réservoir et un capot, d'axe longitudinal X, destiné à être fixé sur le réservoir par l'engagement d'un bourrelet dans une gorge formés respectivement sur le capot et sur le réservoir ou inversement, le récipient pouvant se caractériser par le fait qu'il comporte des moyens, de préférence distincts de la gorge et du bourrelet, destinés à limiter un mouvement axial entre le bourrelet et la gorge lorsque le bourrelet est en engagement avec la gorge.According to the invention, these objects are achieved by producing a container comprising a tank portion and a cover, of longitudinal axis X, intended to be fixed on the tank by the engagement of a bead in a formed groove respectively on the hood and on the tank or vice versa, the container which can be characterized by the fact that it includes means, preferably separate from the groove and the bead, intended to limit axial movement between the bead and the throat when the bead is in engagement with the throat.

Les moyens peuvent en outre être destinés à limiter un mouvement entre le bourrelet et la gorge transversalement à l'axe X lorsque le bourrelet est en engagement avec la gorge.The means may also be intended to limit movement between the bead and throat transverse to the X axis when the bead is in engagement with the throat.

Ainsi, on peut réaliser des récipients avec des tolérances de fabrication qui sont relativement grandes qui peuvent conduire à des jeux entre le bourrelet et la gorge selon l'axe longitudinal du capot, ou encore transversalement à cet axe, sans pour autant autoriser un mouvement axial ou transversal du capot par rapport au récipient.Thus, it is possible to produce containers with manufacturing tolerances which are relatively large which can lead to clearance between the bead and the groove along the longitudinal axis of the cover, or even transversely to this axis, without allowing axial or transverse movement of the cover relative to the container.

Selon un mode de réalisation, les moyens comprennent au moins une ailette radiale apte à se déformer. De préférence, les moyens peuvent comprendre plusieurs ailettes espacées angulairement les unes des autres, et en particulier au moins trois ailettes radiales disposées par exemple à 120° les unes des autres. De telles ailettes ont une épaisseur relativement faible, à savoir de l'ordre du millimètre de sorte qu'elles peuvent se déformer afin, notamment, de se conformer à la forme de la gorge avec laquelle elles viennent en contact.According to one embodiment, the means comprise at least one fin radial able to deform. Preferably, the means may include several fins spaced angularly from one another, and in particular at least three radial fins arranged for example at 120 ° from each other other. Such fins have a relatively small thickness, namely of the order of a millimeter so that they can deform in order, in particular, to conform to the shape of the groove with which they come into contact.

La (les) ailette(s) peut(vent) être contiguë(s) au bourrelet. Elle(s) peut(vent) s'étendre axialement depuis le sommet du bourrelet, ou encore depuis sa base. La (les) ailette(s) est(sont) par exemple de forme triangulaire.The fin (s) can (wind) be contiguous (s) to the bead. She (s) can (wind) extend axially from the top of the bead, or from its base. The fin (s) is (are) for example of triangular shape.

Selon un mode de réalisation, le bourrelet peut être formé sur la paroi interne du capot et la gorge peut être formée sur la paroi externe du réservoir.According to one embodiment, the bead can be formed on the internal wall of the cover and the groove can be formed on the external wall of the tank.

La gorge peut être une gorge annulaire qui s'étend dans un plan perpendiculaire à l'axe longitudinal du réservoir. The groove may be an annular groove which extends in a plane perpendicular to the longitudinal axis of the tank.

Le bourrelet peut être un bourrelet annulaire qui s'étend de façon continue dans un plan perpendiculaire à l'axe longitudinal du capot. Cela permet notamment d'obtenir un accrochage relativement dur. Alternativement, le bourrelet peut être discontinu, c'est-à-dire formé par plusieurs portions d'arc de cercle angulairement espacées et s'étendant dans un plan perpendiculaire à l'axe longitudinal du capot.The bead may be an annular bead which extends continuously in a plane perpendicular to the longitudinal axis of the cover. This allows in particular to obtain a relatively hard attachment. Alternatively, the bead may be discontinuous, that is to say formed by several portions of arc of angularly spaced circle extending in a plane perpendicular to the longitudinal axis of the hood.

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 illustre une vue éclatée en perspective d'un récipient selon l'invention ;
  • la figure 2 représente en coupe le capot du récipient selon l'invention ;
  • la figure 3A représente en partie le capot ; et
  • la figure 3B représente en partie le capot fixé sur le réservoir.
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • Figure 1 illustrates an exploded perspective view of a container according to the invention;
  • 2 shows in section the cover of the container according to the invention;
  • FIG. 3A partially shows the cover; and
  • Figure 3B partially shows the cover attached to the tank.

Le récipient 10 illustré à la figure 1 comporte un réservoir 20 sur lequel vient se fixer un capot 40.The container 10 illustrated in FIG. 1 comprises a reservoir 20 on which comes attach a cover 40.

Selon l'exemple illustré, le réservoir est sous forme de flacon qui est destiné à contenir un produit, par exemple un produit cosmétique. Le flacon est par exemple réalisé par extrusion soufflage d'un matériau thermoplastique, par exemple en polypropylène. Le produit peut être distribué par une tête de distribution 30 qui comporte par exemple une pompe, et un bouton poussoir prévu pour actionner la pompe. Il est bien évident que le récipient peut ne pas comporter de tête de distribution et que le produit peut être distribué directement par une ouverture du flacon, par simple retournement du flacon ou encore en déformant les parois du flacon, lorsque le produit est sous forme fluide. According to the example illustrated, the reservoir is in the form of a bottle which is intended for contain a product, for example a cosmetic product. The bottle is by example produced by blow molding a thermoplastic material, for example example in polypropylene. The product can be dispensed by a distribution 30 which comprises for example a pump, and a push button designed to activate the pump. Obviously the container may not have a dispensing head and that the product can be dispensed directly by opening the bottle, by simply inverting the bottle or again by deforming the walls of the bottle, when the product is in the form fluid.

Le flacon 20 comprend un corps 21 sensiblement cylindrique, d'axe longitudinal X, fermé à une première extrémité par un fond 22. A l'extrémité opposée au fond, la section transversale diminue progressivement jusqu'à une portion d'accrochage 23 de section transversale circulaire, qui permet la fixation du capot sur le flacon.The bottle 20 comprises a substantially cylindrical body 21, of axis longitudinal X, closed at one end by a bottom 22. At the end opposite the bottom, the cross section gradually decreases to a attachment portion 23 of circular cross section, which allows the fixing the cover on the bottle.

La portion d'accrochage 23 comporte une gorge annulaire 24 délimitée, d'une part, par une paroi annulaire plane 25 qui s'étend radialement à partir du corps 21 dans un plan perpendiculaire à l'axe X, jusqu'au fond de la gorge annulaire 24 et, d'autre part, par un cordon annulaire 26 formé au-dessus de la gorge annulaire 24.The attachment portion 23 comprises an annular groove 24 delimited, of a part, by a flat annular wall 25 which extends radially from the body 21 in a plane perpendicular to the X axis, to the bottom of the annular groove 24 and, on the other hand, by an annular bead 26 formed above the groove ring finger 24.

La portion d'accrochage 23 se raccorde à un col 27 d'axe longitudinal X dont le bord libre délimite une ouverture permettant la sortie du produit contenu dans le réservoir. Selon l'exemple illustré, la tête de distribution 30 est fixée sur le col 27, par exemple au moyen d'une bague filetée.The attachment portion 23 is connected to a neck 27 of longitudinal axis X whose free edge delimits an opening allowing the product contained in The reservoir. According to the example illustrated, the dispensing head 30 is fixed to the neck 27, for example by means of a threaded ring.

Le capot 40 est destiné à se fixer sur le flacon 20 en coopérant avec la portion d'accrochage 23 du flacon de manière à fermer le flacon en enveloppant le col et la tête de distribution. Le capot est par exemple réalisé par injection d'un matériau thermoplastique, par exemple d'un polypropylène. Alternativement, le capot peut être réalisé en polyéthylène, en résine ionomère (par exemple en Surlyn®), ou encore en polyéthylène téréphtalate (PET), en styrène acrylonytrile (SAN), ou en acrylonitrile butadiène styrène (ABS).The cover 40 is intended to be fixed on the bottle 20 by cooperating with the portion hooking 23 of the bottle so as to close the bottle by wrapping the neck and the distribution head. The cover is for example produced by injection of a thermoplastic material, for example polypropylene. Alternatively, the cover can be made of polyethylene, ionomer resin (for example Surlyn®), or polyethylene terephthalate (PET), styrene acrylonytrile (SAN), or acrylonitrile butadiene styrene (ABS).

Le capot est formé par une jupe cylindrique 41 fermée à une première extrémité par une paroi transversale 42 qui peut être plane ou bombée comme on l'a représenté à la figure 2. La jupe 41 se termine, à sa seconde extrémité, par un bord libre 43.The cover is formed by a cylindrical skirt 41 closed at a first end by a transverse wall 42 which can be flat or curved as this has been shown in FIG. 2. The skirt 41 ends at its second end, by a free edge 43.

Un bourrelet annulaire 44 est formé à proximité du bord libre 43, sur la surface interne de la jupe 41. Le bourrelet s'étend radialement de façon continue sur toute la périphérie de la jupe pour permettre un accrochage relativement dur. Alternativement, on peut prévoir que le bourrelet ne soit formé que par des portions annulaires angulairement espacées et formées dans un même plan, ce qui assouplit l'accrochage.An annular bead 44 is formed near the free edge 43, on the surface internal of the skirt 41. The bead extends radially continuously over the entire periphery of the skirt to allow a relatively hard attachment. Alternatively, provision may be made for the bead to be formed only by angularly spaced annular portions formed in the same plane, which eases the grip.

Le bourrelet 44 s'étend dans un plan perpendiculaire à l'axe longitudinal X du capot. Le bourrelet a un profil convexe et son sommet arrondi 440 délimite un diamètre intérieur minimum pour le capot. Le bourrelet se raccorde au bord libre 43 du capot par un chanfrein 441 dont la pente est telle qu'elle facilite l'insertion du capot sur le flacon. De l'autre côté du sommet du bourrelet, le bourrelet se raccorde à la paroi 41 par une portion 442 dont la pente est telle qu'elle permet l'accrochage contre le bord supérieur de la gorge 24 tout en autorisant le démoulage en force du bourrelet.The bead 44 extends in a plane perpendicular to the longitudinal axis X of the cover. The bead has a convex profile and its rounded top 440 delimits a minimum inside diameter for the hood. The bead connects to the edge free 43 of the cover by a chamfer 441 whose slope is such that it facilitates inserting the cover on the bottle. On the other side of the top of the bead, the bead is connected to the wall 41 by a portion 442 whose slope is such that it allows hooking against the upper edge of the groove 24 while authorizing the release in force of the bead.

Des ailettes radiales 45, de forme triangulaire sont formées dans un plan parallèle à l'axe X, au-dessus du bourrelet 44. Elles s'étendent depuis le sommet 440 du bourrelet jusqu'à la surface interne de la jupe 41, et ont un bord libre 450 rectiligne. Il est bien évident qu'elles pourraient comporter un bord libre courbe, par exemple concave ou convexe. Les ailettes 45 sont très fines de manière à pouvoir se déformer contrairement au bourrelet 44 qui est relativement rigide. Le capot comporte par exemple 8 ailettes identiques espacées angulairement de manière régulière.Radial fins 45, of triangular shape are formed in a plane parallel to the X axis, above the bead 44. They extend from the top 440 of the bead up to the internal surface of the skirt 41, and have an edge free 450 straight. It is obvious that they could have an edge free curve, for example concave or convex. The fins 45 are very fine so as to be able to deform unlike the bead 44 which is relatively rigid. The cover comprises for example 8 identical fins angularly spaced evenly.

Lors de la fixation du capot sur le flacon, le bourrelet 44 franchit élastiquement le cordon 26 avant de se loger dans la gorge 24. Dans cette position de fixation, représentée en partie à la figure 3B, le bord libre 43 de la jupe 41 est en butée contre la paroi annulaire plane 25. Dans cette position, le bourrelet 44 est logé dans la gorge 24. Le diamètre interne de la jupe 41, au-dessus du bourrelet est environ égal au diamètre externe du cordon 26 de sorte que ce dernier est destiné à être au contact de la paroi. La portion 442 du bourrelet est destinée à venir au contact du bord inférieur du cordon 26. Toutefois, avec les variations de dimensions qui peuvent se produire dues aux tolérances de fabrication, il arrive que le diamètre externe du cordon soit légèrement inférieur au diamètre interne de la jupe 41 et/ou que la portion 442 du bourrelet soit légèrement en retrait du bord inférieur du cordon 26. Dans un tel cas, le bord 450 des ailettes vient s'écraser sur le cordon 26 et se déforme du fait de la faible épaisseur des ailettes pour s'adapter à la forme du cordon 26, comme on le voit sur la figure 3B. Ainsi, grâce à la présence des ailettes, le capot ne peut plus bouger axialement ni transversalement par rapport au flacon.When fixing the cover on the bottle, the bead 44 passes elastically the cord 26 before being housed in the groove 24. In this position of attachment, shown in part in FIG. 3B, the free edge 43 of the skirt 41 is in abutment against the flat annular wall 25. In this position, the bead 44 is housed in the groove 24. The internal diameter of the skirt 41, above the bead is approximately equal to the external diameter of the cord 26 so that this the latter is intended to be in contact with the wall. The portion 442 of the bead is intended to come into contact with the lower edge of the cord 26. However, with the dimensional variations which may occur due to tolerances of manufacturing, sometimes the external diameter of the cord is slightly smaller the internal diameter of the skirt 41 and / or that the portion 442 of the bead is slightly set back from the lower edge of the cord 26. In such a case, the edge 450 of the fins comes crashing onto the bead 26 and deforms due to the small thickness of the fins to adapt to the shape of the cord 26, as is seen in Figure 3B. Thus, thanks to the presence of the fins, the hood cannot no longer move axially or transversely relative to the bottle.

Selon un exemple de réalisation, le diamètre interne d de la jupe 41, au-dessus du bourrelet est environ égal à 31,06 mm, à ± 0,2 mm. La longueur l mesurée entre le bord libre 43 et la jonction entre la portion 443 du bourrelet et la paroi 41 est égale à 2,1 mm ± 0,1 mm. L'épaisseur e du bourrelet mesurée radialement est égale à 0,5 mm ± 0,1 mm. La hauteur axiale p de la gorge 24 est par exemple égale à 1,5 mm ±0,1 mm. Les ailettes 46 ont une épaisseur d'environ 0,45 mm et s'étendent sur une hauteur axiale h environ égale à 1,2 mm. La largeur des ailettes, mesurée radialement, diminue de façon linéaire le long de cette hauteur axiale, entre une extrémité inférieure située à la hauteur axiale du sommet du bourrelet, et une extrémité supérieure. A leur extrémité inférieure, la largeur des ailettes est égale à l'épaisseur radiale e du bourrelet, puis elle diminue jusqu'à rejoindre la paroi 41 au niveau de l'extrémité supérieure.According to an exemplary embodiment, the internal diameter d of the skirt 41, above the bead is approximately equal to 31.06 mm, to ± 0.2 mm. The length l measured between the free edge 43 and the junction between the portion 443 of the bead and the wall 41 is equal to 2.1 mm ± 0.1 mm. The thickness e of the bead measured radially is equal to 0.5 mm ± 0.1 mm. The axial height p of the groove 24 is for example equal to 1.5 mm ± 0.1 mm. The fins 46 have a thickness of approximately 0.45 mm and extend over an axial height h approximately equal to 1.2 mm. The width of the fins, measured radially, decreases linearly along this axial height, between a lower end situated at the axial height of the top of the bead, and an upper end. At their lower end, the width of the fins is equal to the radial thickness e of the bead, then it decreases until it reaches the wall 41 at the upper end.

Bien entendu, les dimensions des ailettes sont déterminées en fonction du jeu à rattraper entre le capot et la gorge. Elles sont également choisies en fonction du matériau dans lequel elles sont réalisées et en particulier en fonction de la souplesse du matériau. En effet, plus le matériau utilisé est rigide, plus les ailettes devront être fines de manière à pouvoir se déformer et se conformer à la forme de la gorge.Of course, the dimensions of the fins are determined according to the play to be caught between the hood and the groove. They are also chosen according to of the material in which they are made and in particular depending on the flexibility of the material. The more rigid the material used, the more fins must be thin so that they can deform and conform to the shape of the throat.

Selon une variante non représentée, la gorge peut être formée sur la paroi interne du capot dans l'épaisseur de celle-ci. Le bourrelet et les ailettes sont alors formés sur la surface externe du flacon. Selon cette variante, afin de former avec précision les ailettes, le flacon sera de préférence réalisé non pas par extrusion soufflage mais par injection soufflage, le col du flacon ainsi que la base du col comportant le bourrelet et les ailettes étant réalisés par injection et le corps du flacon étant soufflé.According to a variant not shown, the groove can be formed on the wall internal cover in the thickness thereof. The bead and the fins are then formed on the outer surface of the vial. According to this variant, in order to form the fins with precision, the bottle should preferably be made not by blowing extrusion but by blowing injection, the neck of the bottle as well as the base of the neck comprising the bead and the fins being produced by injection and the body of the bottle being blown.

Le récipient qui vient d'être décrit comporte un réservoir sous forme de flacon mais il est bien évident qu'il peut être formé par un réservoir de toute autre forme, par exemple sous forme d'un pot.The container which has just been described comprises a reservoir in the form of a bottle but it is quite obvious that it can be formed by a reservoir of any other form, for example in the form of a pot.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. It is obvious that there are variations be made without departing from the invention as claimed below.
