Description

CAPSULE DE DISTRIBUTION A ETANCHEITE AMELIOREE DISTRIBUTION CAPSULE WITH IMPROVED SEALING
La présente invention se rapporte à une capsule de distribution destinée à équiper un réservoir contenant un produit fluide à distribuer, ainsi qu'a un ensemble de distribution équipé de cette capsule Elle est équipée d'un système de bouchage, pouvant être ouvert pour la distribution du produit, et fermé pour sa conservationThe present invention relates to a dispensing capsule intended to equip a reservoir containing a fluid product to be dispensed, as well as to a dispensing assembly equipped with this capsule. It is equipped with a closure system, which can be opened for dispensing. of the product, and closed for its conservation
Des réservoirs munis d'une capsule de ce genre sont utilisés habituellement dans différents domaines, pour le stockage et la distribution de produits liquides, par exemple dans les domaines cosmétique, alimentaire, ménager, pharmaceutique ou parapharmaceutique Ces produits sont, notamment, des shampooings, des antiseptiques, des nettoyants ménagers ou des produits pour la vaisselle Grâce à l'utilisation d'une telle capsule, on évite, d'une part, l'écoulement du produit pendant le transport et le stockage, et d'autre part, on protège le produit des salissures de provenant de l'extérieur D'autre part, avec une telle capsule, l'utilisateur peut distribuer aisément, de façon contrôlée, le produit contenu dans le réservoirReservoirs provided with a capsule of this kind are usually used in different fields, for the storage and distribution of liquid products, for example in the cosmetic, food, household, pharmaceutical or parapharmaceutical fields. These products are, in particular, shampoos, antiseptics, household cleaners or dishwashing products Thanks to the use of such a capsule, we avoid, on the one hand, the flow of the product during transport and storage, and on the other hand, protects the product from dirt from the outside On the other hand, with such a capsule, the user can easily dispense, in a controlled manner, the product contained in the tank
Plus particulièrement, la présente invention se rapporte a une capsule comportant un orifice de distribution de produit et un couvercle pivotant, le système de bouchage de l'orifice étant constitué par un picot porté par le couvercle, prévu pour fermer cet orificeMore particularly, the present invention relates to a capsule comprising a product dispensing orifice and a pivoting cover, the closure system of the orifice being constituted by a pin carried by the cover, intended to close this orifice.
Le picot introduit dans l'orifice de distribution doit satisfaire à plusieurs fonctions , il doit garantir une bonne étanchéité , la force d'ouverture doit être raisonnable, et, lors de l'ouverture, il ne doit pas se produire un bruit de pistonnage Ces qualités doivent être assurées tout au long de l'utilisation du produit Or, avec les matériaux couramment utilisés pour l'injection de telles capsules, tels que le polyéthylène ou le polypropyiène, le réglage dimensionnel est très délicat, car les tolérances doivent rester en-dessous de 0,05 mm, d'autant plus que des déformations supplémentaires risquent de se produire lors du démoulage En outre, lors d'une utilisation intense, par l'usure du picot et/ou de l'orifice, ce picot ne rentre plus à friction dans l'orifice et, par conséquent, des fuites de produit peuvent se produireThe pin introduced into the dispensing orifice must fulfill several functions, it must guarantee a good seal, the opening force must be reasonable, and, when opening, no pistoning noise should occur. qualities must be ensured throughout the use of the Gold product, with the materials commonly used for the injection of such capsules, such as polyethylene or polypropyiene, the dimensional adjustment is very delicate, because the tolerances must remain within below 0.05 mm, all the more that additional deformations are likely to occur during demolding In addition, during intense use, by wear of the pin and / or the orifice, this pin does not fit more friction in the orifice and, therefore, product leakage may occur
Une capsule de distribution du genre de celle mentionnée ci-dessus, est décrite, par exemple, dans le document FR-A-2 662 144 Ce document décrit une capsule de distribution comportant un orifice de distribution et un couvercle pivotant muni d'un picot creux, destine à boucher l'orifice de distribution en position de stockage, ce picot se présentant sous la forme d'une jupe cylindrique Suivant ce document, l'orifice de distribution est ménagé dans une portion plane, perpendiculaire à l'axe longitudinal de la capsule, cette portion étant réalisée en caoutchouc thermoélastiqueA dispensing capsule of the kind mentioned above is described, for example, in document FR-A-2 662 144. This document describes a dispensing capsule comprising a dispensing orifice and a pivoting cover provided with a spike. hollow, intended to plug the dispensing orifice in the storage position, this pin being in the form of a cylindrical skirt According to this document, the dispensing orifice is formed in a flat portion, perpendicular to the longitudinal axis of the capsule, this portion being made of thermoelastic rubber
Cette capsule de l'art antérieur présente l'inconvénient, que, lorsqu'on ferme le couvercle, un effort relativement important est nécessaire pour engager le picot dans l'orifice de distribution En effet, lors de l'opération de fermeture, le picot est au contact avec le bord de l'orifice et, avant de s'engager dans l'orifice, repousse ladite portion en caoutchoucThis capsule of the prior art has the disadvantage that, when the lid is closed, a relatively large effort is necessary to engage the pin in the dispensing orifice. In fact, during the operation of closure, the pin is in contact with the edge of the orifice and, before engaging in the orifice, repels said rubber portion
On connaît, également, par le document US-A-5 169 035, une capsule semblable à la capsule précitée, l'orifice de distribution étant réalisé par une pièce annulaire en éiastomère, clipsée dans une ouverture de la face supérieure de la capsule et obturée par un picot porte par le couvercle articule avec la capsuleAlso known from document US-A-5,169,035, a capsule similar to the aforementioned capsule, the dispensing orifice being produced by an annular piece of elastomer, clipped into an opening in the upper face of the capsule and closed by a pin carried by the hinged lid with the capsule
Bien que la capsule selon US-A-5 169 035 permette d'obtenir un bouchage étanche de l'orifice de distribution par le picot, elle présente les inconvénients suivants - d'une part, la pièce en éiastomère doit présenter une épaisseur importante pour pouvoir assurer son maintien dans l'ouverture de la capsule , - d'autre part, le choix des élastomères utilisables pour la réalisation de la pièce annulaire est limité En effet, en vue d'un engagement souple et étanche a la fois du picot dans l'orifice de distribution, il serait souhaitable d'utiliser des élastomères dits "mous" (c'est-à-dire des élastomères dont la dureté est inférieure a environ 60 Shore A) Or, pour assurer un bon maintien de la pièce en éiastomère dans l'ouverture de la capsule, ce matériau doit présenter une dureté supérieure à 60 Shore A, ce qui est préjudiciable au fonctionnement souple et à l'étanchéité souhaités de la capsule En outre, avec un tel matériau, les tolérances de dimension et de positionnement du picot par rapport à l'orifice de distribution peuvent être moins bien rattrapées Enfin, le montage de la pièce annulaire dans l'orifice par l'intérieur de la capsule est relativement compliqué et nécessite un outillage approprié particulierAlthough the capsule according to US-A-5 169 035 makes it possible to obtain a tight plugging of the dispensing orifice by the spike, it has the following drawbacks - on the one hand, the elastomer part must have a significant thickness for being able to maintain it in the opening of the capsule, - on the other hand, the choice of elastomers which can be used for the production of the annular part is limited In fact, with a view to flexible and waterproof engagement both of the pin in the dispensing orifice, it would be desirable to use so-called "soft" elastomers (that is to say elastomers whose hardness is less than about 60 Shore A). Gold, to ensure good retention of the part in Elastomer in the opening of the capsule, this material must have a hardness greater than 60 Shore A, which is detrimental to the flexible operation and the desired tightness of the capsule In addition, with such a material, the dimensional tolerances n and positioning of the pin relative to the dispensing orifice may be less well caught Finally, the mounting of the annular part in the orifice from the inside of the capsule is relatively complicated and requires special appropriate tools
La présente invention a pour premier objet une capsule de distribution présentant un fonctionnement souple lors de son ouverture ou de sa fermeture, dans des bonnes conditions d'étanchéité et dont le prix de revient est compétitifThe present invention firstly relates to a dispensing capsule having flexible operation when it is opened or closed, in good sealing conditions and the cost price of which is competitive.
Un second objet de l'invention est constitué par une capsule de distribution dont le réglage des tolérances des dimensions du picot et/ou de l'orifice de distribution est aisé et dont les défauts de moulage/démoulage peuvent être rattrapes Un autre objet de l'invention est de créer un système de bouchage particulièrement étanche, résistant à l'usure pendant toute la durée de vie du produit et assurant un fonctionnement souple, ainsi qu'un fonctionnement d'ouverture et de fermeture aisé En outre, l'invention vise avantageusement l'utilisation d'orifices de section non circulaires, alors jusqu'à maintenant inconnus dans les domaines d'utilisation précitésA second object of the invention consists of a dispensing capsule, the setting of the tolerances of the dimensions of the spike and / or of the dispensing orifice is easy and whose molding / demolding defects can be remedied. Another object of the invention is to create a particularly sealed closure system, resistant to wear throughout the life of the product and ensuring flexible operation, as well as easy opening and closing operation In addition, the invention aims advantageously the use of non-circular section orifices, which until now have been unknown in the aforementioned fields of use
Les objectifs visés ci-dessus sont atteints en déposant un revêtement en matériau élastomérique sur la paroi externe du picot Le dépôt de ce revêtement, dans l(hypothese où il est réalise par bi-injection ou par surmoulage sur le picot, est plus facile à réaliser que la réalisation, selon l'art antérieur, d'un orifice de distribution pratiqué dans une zone en éiastomère En outre, la réalisation d'un revêtement sur la paroi externe du picot permet, d'une part, de réaliser ce revêtement une couche de fine épaisseur, donc d'économiser du matériau, et, d'autre part, d'utiliser des élastomères particulièrement souples (de dureté inférieure à 60 Shore A), ce qui confère à la capsule un fonctionnement souple et une étanchéité parfaite.The above-mentioned objectives are achieved by depositing a coating of elastomeric material on the external wall of the spike The deposition of this coating, in the event that it is carried out by bi-injection or by overmolding on the spike, is easier to realize that the realization, according to the prior art, of a dispensing orifice made in an elastomer zone In addition, the realization of a coating on the external wall of the pin allows, on the one hand, to achieve this coating a thin layer, so to save material, and, on the other hand, to use particularly flexible elastomers (of hardness less than 60 Shore A), which gives the capsule a flexible operation and a perfect seal.
Ainsi, l'invention se rapporte à une capsule de distribution destinée à équiper un flacon contenant un produit fluide, comportant un corps pourvu d'un orifice de distribution et d'un couvercle pivotant, articulé avec le corps autour d'un axe, le corps et le couvercle étant réalisés en un matériau rigide ou semi- rigide, ce couvercle étant pourvu d'un picot de bouchage, destiné à boucher l'orifice de distribution en position de stockage. Selon l'invention, un revêtement en matériau élastomérique est déposé sur la paroi externe du picot, pour assurer, en position fermée du couvercle, une étanchéité parfaite entre le picot et l'orifice dans ladite position de stockage.Thus, the invention relates to a dispensing capsule intended to equip a bottle containing a fluid product, comprising a body provided with a dispensing orifice and a pivoting cover, articulated with the body around an axis, the body and the cover being made of a rigid or semi-rigid material, this cover being provided with a plugging pin, intended to plug the dispensing orifice in the storage position. According to the invention, a coating of elastomeric material is deposited on the external wall of the pin, to ensure, in the closed position of the cover, a perfect seal between the pin and the orifice in said storage position.
Un autre objet de l'invention est constitué par un ensemble de distribution comportant un réservoir de produit, équipé d'une capsule conforme à l'invention telle que décrite précédemmentAnother object of the invention is constituted by a distribution assembly comprising a product reservoir, equipped with a capsule according to the invention as described above.
Généralement, le réservoir équipé d'une telle capsule est constitué par un flacon plus ou moins souple, ou bien par un tube compressible. De préférence, ce réservoir comporte un col, sur lequel est fixée, par vissage, claquage, surmoulage, soudage ou tout autre moyen connu, la capsule de distributionGenerally, the reservoir equipped with such a capsule is constituted by a more or less flexible bottle, or else by a compressible tube. Preferably, this reservoir has a neck, on which is fixed, by screwing, snapping, overmolding, welding or any other known means, the dispensing capsule.
Le produit à distribuer est capable de s'écouler sous son propre poids et est, par exemple, un shampooing ou un lait corporel dont la viscosité est comprise généralement dans une gamme allant de 50 mPa-s à 5 Pa s ou bien un produit pulvérulentThe product to be dispensed is capable of flowing under its own weight and is, for example, a shampoo or body milk whose viscosity is generally in a range from 50 mPa-s to 5 Pa s or a powdery product
L'orifice de distribution peut présenter une section circulaire, ovale, polygonale ou allongée, la section du picot étant complémentaire à celle de l'orifice Grâce à l'invention, il est envisageable de réaliser des orifices, notamment de section non circulaire sans qu'il se crée de problème de défaut d'étanchéité.The dispensing orifice may have a circular, oval, polygonal or elongated section, the section of the pin being complementary to that of the orifice. Thanks to the invention, it is possible to make orifices, in particular of non-circular section without 'there is a problem with a leak.
Grâce à la souplesse du revêtement, des défauts mineurs de positionnement du picot par rapport à l'orifice peuvent être rattrapés II en est de même, pour des différences des diamètres respectifs de l'orifice et du picot Notamment, lorsqu'on veut réaliser des orifices de forme non circulaire, par exemple sous forme d'étoile ou de bande plate, une bonne étanchéité peut être obtenue, en disposant d'un revêtement en matériau élastomérique sur la paroi externe du picot, tout en assurant un fonctionnement souple d'ouverture et de fermeture de l'orifice de distribution.Thanks to the flexibility of the coating, minor defects in positioning the pin relative to the orifice can be made up. The same is true, for differences in the respective diameters of the orifice and the pin. In particular, when one wishes to make orifices of non-circular shape, for example in the form of a star or a flat strip, good sealing can be obtained by having a coating of elastomeric material on the external wall of the pin, while ensuring a flexible opening operation and closing the dispensing orifice.
Avantageusement, le revêtement externe du picot présente une épaisseur comprise entre environ 0,1 mm et 3 mm Selon un autre aspect intéressant de l'invention, on peut réaliser un picot creux, formé par une jupe cylindrique. Dans ce cas, le volume interne du picot peut être rempli de matériau souple. Ceci est avantageux, car on évite un emprisonnement temporaire de résidus de produit à l'intérieur du picot, résidus qui risquent de s'écouler intempestivement, lors de l'ouverture du couvercle et souiller le plan de travailAdvantageously, the external coating of the pin has a thickness of between approximately 0.1 mm and 3 mm According to another interesting aspect of the invention, a hollow pin can be produced, formed by a cylindrical skirt. In this case, the internal volume of the pin can be filled with flexible material. This is advantageous because it avoids a temporary trapping of product residues inside the spike, residues which may run out unexpectedly, when the lid is opened and soil the work surface.
Avantageusement, le couvercle est articulé avec le corps de capsule à l'aide d'une charnière pivotante autour d'un axe Cette charnière est, de préférence, une charnière-film venue de matière lors du moulage du corps de capsule et du couvercleAdvantageously, the cover is articulated with the capsule body using a hinge pivoting about an axis. This hinge is preferably a film hinge made of material during the molding of the capsule body and the cover.
De préférence, la capsule et son couvercle sont réalisés en un matériau thermoplastique rigide ou semi-rigide, par exemple en polypropylène ou en polyéthylène de haute ou basse densité.Preferably, the capsule and its cover are made of a rigid or semi-rigid thermoplastic material, for example polypropylene or high or low density polyethylene.
Selon un premier mode de réalisation, le matériau souple peut être un éiastomère thermoplastique physico-chimiquement compatible avec le matériau rigide ou semi-rigide, capable de former, lors de la réalisation de la capsule par exemple par bi-injection ou surmoulage, une liaison par thermofusion avec le matériau rigide ou semi-rigideAccording to a first embodiment, the flexible material can be a physico-chemically compatible thermoplastic elastomer compatible with the rigid or semi-rigid material, capable of forming, during the production of the capsule, for example by bi-injection or overmolding, a bond by thermofusion with rigid or semi-rigid material
Selon ce mode de réalisation, cet éiastomère thermoplastique est choisi, avantageusement, dans le groupe des élastomères de polyéther blocamides , des polyvinyles , des terpolymères d'éthylène, de propylène et d'un dièneAccording to this embodiment, this thermoplastic elastomer is advantageously chosen from the group of elastomers of polyether blockamides, polyvinyls, terpolymers of ethylene, propylene and a diene
(EPDM) , des polymères de styrène-éthylène-butadiene séquences (SEBS-(EPDM), styrene-ethylene-butadiene block polymers (SEBS-
SIS)SIS)
Selon un autre mode de réalisation, le matériau souple est choisi parmi les caoutchoucs naturelles ou synthétiques, ou bien parmi les caoutchoucs de siliconeAccording to another embodiment, the flexible material is chosen from natural or synthetic rubbers, or else from silicone rubbers
Selon un autre mode de réalisation encore, ledit revêtement est constitué d'une pièce rapportée en éiastomère déposée sur la paroi externe du picot par assemblageAccording to yet another embodiment, said coating consists of an elastomer insert deposited on the external wall of the pin by assembly
Avantageusement, cet assemblage peut être effectué, par exemple, par claquage, collage, soudure, étirement, boutrollage ou tout autre moyen approprié Le montage par étirement est tout particulièrement avantageux en ce qu'il autorise des épaisseurs plus finesAdvantageously, this assembly can be carried out, for example, by snapping, gluing, welding, stretching, rolling or any other suitable means. The assembly by stretching is very particularly advantageous in that it allows thinner thicknesses.
Avantageusement, le matériau souple est choisi de sorte que le revêtement présente une dureté comprise entre 20 Shore A et 90 Shore A, et de préférence comprise entre 30 Shore A et 60 Shore AAdvantageously, the flexible material is chosen so that the coating has a hardness of between 20 Shore A and 90 Shore A, and preferably between 30 Shore A and 60 Shore A
La capsule de l'invention peut être munie d'un certain nombre de dispositions complémentaires, décrites ci-après Ainsi, une partie du corps et/ou du couvercle peut être pourvue d'une zone de préhension comportant une zone en matériau souple, réalisée en même temps que le revêtement du picot, par surmoulage ou bi-injection du corps de capsule. Cette zone de préhension facilite l'ouverture et la fermeture du couvercle, du fait d'un effet anti-dérapant que présentent certains élastomères. Ceci est avantageux, notamment lorsque les mains de l'utilisateur sont mouillées, par exemple sous la douche.The capsule of the invention can be provided with a certain number of additional provisions, described below. Thus, a part of the body and / or of the cover can be provided with a gripping zone comprising a zone made of flexible material, produced at the same time as the coating of the pin, by overmolding or bi-injection of the capsule body. This gripping area facilitates the opening and closing of the cover, due to the non-slip effect that certain elastomers exhibit. This is advantageous, especially when the user's hands are wet, for example in the shower.
De plus, le corps de la capsule peut comporter un joint annulaire en matériau souple, en contact étanche avec un bord périphérique du couvercle, lorsque ce dernier est en position rabattue.In addition, the capsule body may include an annular seal made of flexible material, in leaktight contact with a peripheral edge of the cover, when the latter is in the folded position.
Il est envisageable, également, de prévoir au moins un élément de liaison en matériau souple, élastiquement déformable en élongation, formant ressort. Dans ce cas, l'une des extrémités de l'élément de liaison est solidaire du corps, l'autre est solidaire du couvercle. L'élément de liaison est monté de manière à être situé d'un côté de l'axe de pivotement du couvercle lorsque celui-ci est en position ouverte, et de l'autre côté de l'axe de pivotement lorsque le couvercle est en position fermée. L'élément de liaison subit une élongation lors du passage de la position ouverte à la position fermée, ou inversement, et dont le maximum est atteint lors du passage de l'élément de liaison dans l'axe de pivotement. Cet élément est ainsi apte à maintenir, à volonté, le couvercle dans deux positions extrêmes : dans une position totalement ouverte ou dans une position fermée ou quasi-fermée.It is also conceivable to provide at least one connecting element of flexible material, elastically deformable in elongation, forming a spring. In this case, one of the ends of the connecting element is secured to the body, the other is secured to the cover. The connecting element is mounted so as to be situated on one side of the pivot axis of the cover when the latter is in the open position, and on the other side of the pivot axis when the lid is in closed position. The connecting element undergoes an elongation when passing from the open position to the closed position, or vice versa, and the maximum of which is reached during the passage of the connecting element in the pivot axis. This element is thus able to maintain, at will, the cover in two extreme positions: in a fully open position or in a closed or almost closed position.
Les dispositions mentionnées ci-dessus, à savoir la bande élastique, le revêtement externe du picot ou interne de l'orifice, le surmoulage des zones de préhension et le joint annulaire peuvent être réalisées en une seule étape de fabrication en utilisant le procédé de bi-injection, consistant à injecter en une seule et même pièce, dans un moule approprié, en un premier temps, la capsule articulée avec le couvercle en matériau rigide ; dans un deuxième temps, on réalise la bande élastique, le revêtement du picot ou de l'orifice, le surmoulage des zones de préhension et le joint annulaire en matériau thermoplastique souple.The arrangements mentioned above, namely the elastic band, the external coating of the spike or the internal of the orifice, the overmolding of the gripping zones and the annular seal can be carried out in a single manufacturing step using the bi-process. -injection, consisting in injecting in a single piece, in a suitable mold, firstly, the articulated capsule with the cover of rigid material; in a second step, the elastic band is produced, the coating of the spike or the orifice, the overmolding of the gripping zones and the annular seal in flexible thermoplastic material.
Pour mieux faire comprendre l'objet de l'invention, on va décrire, maintenant, à titre d'exemples purement illustratifs et non limitatifs, deux modes de réalisation de capsule de distribution conforme à l'invention, en référence aux dessins annexés.To better understand the object of the invention, a description will now be given, by way of purely illustrative and nonlimiting examples, of two embodiments of a dispensing capsule in accordance with the invention, with reference to the accompanying drawings.
- La figure 1 représente, en coupe axiale, un ensemble de distribution, en position ouverte, comprenant un réservoir muni d'une capsule de distribution, selon l'invention ;- Figure 1 shows, in axial section, a distribution assembly, in the open position, comprising a reservoir provided with a distribution capsule, according to the invention;
- la figure 2 représente, une vue de dessus de la capsule de la figure 1 ;- Figure 2 shows a top view of the capsule of Figure 1;
- la figure 3 montre une vue de dessus d'une variante de la capsule de la figure 1 ; - la figure 4 montre une coupe axiale d'une autre variante de la capsule de la figure 1- Figure 3 shows a top view of a variant of the capsule of Figure 1; - Figure 4 shows an axial section of another variant of the capsule of Figure 1
En référence, à la figure 1, on peut voir un ensemble de distribution désigne dans son ensemble par la référence 1 , comportant un réservoir 21 ayant un axe longitudinal X, équipé d'une capsule de distribution 3 pourvue un corps de référence 32 Le réservoir 21 comporte un fond fermé 22 et, du côté opposé au fond, un goulot 2 muni d'un filetage externe 24 pour la fixation du corps 32 de capsule sur le réservoir A cet effet, le corps de capsule comporte une jupe interne cylindrique 25, munie d'un filetage interne complémentaire au filetage 24 du goulot 2 Le réservoir 21 a une section générale circulaire ou ovale, mais celle- ci peut être quelconque, par exemple polygonale ou dissymétrique II est réalise, par exemple, en polyéthylène haute densité Le corps de la capsule, quant a lui, est réalisé en un matériau rigide, comme le polypropyleneWith reference to FIG. 1, a distribution assembly can be seen designated as a whole by the reference 1, comprising a reservoir 21 having a longitudinal axis X, equipped with a distribution capsule 3 provided with a reference body 32 The reservoir 21 has a closed bottom 22 and, on the side opposite the bottom, a neck 2 provided with an external thread 24 for fixing the capsule body 32 to the reservoir. For this purpose, the capsule body has a cylindrical internal skirt 25, provided with an internal thread complementary to the thread 24 of the neck 2 The reservoir 21 has a general circular or oval section, but this may be any, for example polygonal or asymmetrical II is produced, for example, in high density polyethylene The body of the capsule, meanwhile, is made of a rigid material, such as polypropylene
Le corps 32 de la capsule 3 comporte un plateau 34, pourvu sur une portion de sa périphérie d'une charniere-film 8, a l'aide de laquelle est articule un couvercle 5, permettant à ce dernier de pivoter autour d'un axe A constituant l'axe de la charnière Le couvercle 5 a une forme de calotte muni d'un bord périphérique 51 tourné vers le réservoir Dans le plateau 34, du côté oppose à la charnière 8 et dans un plan passant par la charnière et par l'axe X du réservoir 21 , est prévu un orifice de distribution 4 L'orifice 4 est défini par une tubulure cylindrique 41 , 42, s'etendant de part et d'autre du plateau 34 Une partie émergente 41 de la tubulure présente une forme interne conique, s'evasant vers l'extérieur Cette tubulure constitue un réducteur de débit, la partie 41 émergente ayant la fonction d'un bec verseurThe body 32 of the capsule 3 comprises a plate 34, provided on a portion of its periphery with a film hinge 8, by means of which a cover 5 is hinged, allowing the latter to pivot about an axis A constituting the axis of the hinge The cover 5 has a shape of a cap provided with a peripheral edge 51 turned towards the reservoir In the plate 34, on the side opposite the hinge 8 and in a plane passing through the hinge and through the axis X of the reservoir 21, a dispensing orifice 4 is provided The orifice 4 is defined by a cylindrical tube 41, 42, extending on either side of the plate 34 An emerging part 41 of the tube has a shape conical internal, flaring outwards This tubing constitutes a flow reducer, the emerging part 41 having the function of a pouring spout
La charnière 8 est formée en deux parties 8a, 8b séparées par un evidement 8c Deux barrettes 12, 13 d'orientation parallèle a l'axe A traversent l'evidement Ces barrettes 12, 13 sont noyées dans une bande plate 10 en matériau éiastomère et constituent des moyens d'ancrage de la bande Les extrémités de cette bande sont solidaires du corps 32 de la capsule et du couvercle 5 respectivement, la solidansation de cette bande 10 sur le corps 32 et le couvercle 5 étant obtenue par thermofusion des matériaux respectifs lors de la fabrication de la capsule 3 Pour renforcer d'avantage la tenue de la bande 10, des points d'ancrage supplémentaires 14 peuvent être prévus sur chaque partie attenante aux extrémités de la bande 10The hinge 8 is formed in two parts 8a, 8b separated by a recess 8c Two bars 12, 13 of orientation parallel to the axis A pass through the recess These bars 12, 13 are embedded in a flat strip 10 of elastomeric material and constitute means for anchoring the strip The ends of this strip are integral with the body 32 of the capsule and the cover 5 respectively, the fastening of this strip 10 on the body 32 and the cover 5 being obtained by thermofusion of the respective materials during of the manufacture of the capsule 3 To further strengthen the holding of the strip 10, additional anchoring points 14 may be provided on each part adjoining the ends of the strip 10
Cette bande 10 est monte de manière a se situer d'un côte de l'axe A en position ouverte du couvercle 5, et de l'autre côte de l'axe A en position fermée du couvercle Ainsi, la bande 10 subit une élongation lors de son passage d'une des positions à l'autre et dont le maximum est atteint lors du passage de la bande 10 au niveau de l'axe A Une fois franchie la zone d'élongation maximum, le couvercle 5 est rappelé soit dans sa position ouverte, soit dans sa position fermée ou quasi-fermée A partir de la position quasi-fermée, le couvercle 5 peut être ferme complètement en faisant rentrer, a friction, le picot 6 dans l'orifice 4 La bande souple 10 est réalisée, par exemple, en un mélange de polypropylene / polymère de bloc de styrène - éthylene - butylène - styrène L'orifice de distribution 4 est bouché, en position rabattue du couvercle, par un picot 6 obturant la partie tubulaire 41. Ce picot 6 est creux et porte un revêtement externe 72 en matériau souple. Les diamètres interne de la partie tubulaire 41 et externe du revêtement 72 sont choisis de sorte que le picot 6 puisse rentrer à friction, de façon étanche, dans l'orifice 4, lorsqu'on ferme le couvercle 5. Avantageusement, ce diamètre est de l'ordre de 3 à 8 mm, en fonction de la viscosité du produit à distribuer. Typiquement, cette viscosité est comprise dans la gamme allant de 50 mPa-s à 5 Pa sThis strip 10 is mounted so as to be situated on one side of the axis A in the open position of the cover 5, and on the other side of the axis A in the closed position of the cover. Thus, the strip 10 undergoes an elongation. during its passage from one of the positions to the other and the maximum of which is reached during the passage of the strip 10 at the level of the axis A Once the maximum elongation zone has been crossed, the cover 5 is recalled either in its open position, either in its closed or quasi-closed position From the quasi-closed position, the cover 5 can be closed completely by causing the stud 6 to enter, in friction, in the orifice 4 The flexible strip 10 is produced , for example, a blend of polypropylene / styrene-ethylene-butylene-styrene block polymer The dispensing orifice 4 is blocked, in the folded-down position of the cover, by a pin 6 closing off the tubular part 41. This pin 6 is hollow and carries an external coating 72 made of flexible material. The internal diameters of the tubular part 41 and external of the covering 72 are chosen so that the pin 6 can frictionally enter, in a sealed manner, in the orifice 4, when the cover 5 is closed. Advantageously, this diameter is around 3 to 8 mm, depending on the viscosity of the product to be dispensed. Typically, this viscosity is in the range from 50 mPa-s to 5 Pa s
Il est possible, bien entendu, de réaliser une pièce distincte sous forme de manchon cylindrique en éiastomère, dont le diamètre interne est légèrement inférieur au diamètre du picot. Après étirement radial du manchon, ce dernier peut être pose sur le picot où il est maintenu par élasticitéIt is of course possible to produce a separate piece in the form of a cylindrical elastomer sleeve, the internal diameter of which is slightly less than the diameter of the pin. After radial stretching of the sleeve, it can be placed on the pin where it is held by elasticity
Comme visible sur les figures 1 et 2, l'intérieur 71 du picot 6 peut être rempli d'un matériau élastomériqueAs shown in Figures 1 and 2, the interior 71 of the pin 6 can be filled with an elastomeric material
Comme illustré, notamment sur la figure 2, le plateau 34 comporte en outre, à sa périphérie, un joint annulaire 11 en matériau élastomérique II est disposé de sorte que le bord 51 du couvercle 5 vienne en appui contre ce joint 11 , en position de fermeture de la capsule.As illustrated, in particular in FIG. 2, the plate 34 further comprises, at its periphery, an annular seal 11 made of elastomeric material II is arranged so that the edge 51 of the cover 5 comes to bear against this seal 11, in the position of closure of the capsule.
Du côté opposé à la charnière 8, la jupe 37 présente une zone en dépression 95 en forme d'arc de cercle par exemple, facilitant la préhension et l'ouverture du couvercle 5. La surface 96 de cette zone est recouverte par une couche de matériau souple. De même, le couvercle 5 comporte une zone de préhension 91 en forme de retour concave 9, cette zone étant recouverte, également, de matériau souple L'utilisation d'un matériau souple pour les zones de préhension confère à l'utilisateur un toucher agréable et une manipulation aisée de la capsule En choisissant un matériau souple particulier, par exemple duOn the side opposite to the hinge 8, the skirt 37 has a depression area 95 in the form of an arc of a circle for example, facilitating the gripping and opening of the cover 5. The surface 96 of this area is covered by a layer of flexible material. Likewise, the cover 5 comprises a gripping zone 91 in the form of a concave return 9, this zone being also covered with flexible material. The use of a flexible material for the gripping zones gives the user a pleasant touch. and easy handling of the capsule By choosing a particular flexible material, for example
SANTOPRENEm® (mélange de polypropylene avec des terpolymères d'éthylène, de propylène et d'un diène (EPDM)), commercialisé par la société AES En utilisant un matériau de ce type, il est même possible d'obtenir un effet « antiglisse », ce qui est intéressant lorsque l'utilisateur utilise, sous la douche ou dans le bain, un produit tensioactif de nettoyage corporelSANTOPRENEm ® (mixture of polypropylene with terpolymers of ethylene, propylene and a diene (EPDM)), sold by the company AES By using a material of this type, it is even possible to obtain an "anti-slip" effect , which is interesting when the user uses, in the shower or in the bath, a surface-cleaning product for body cleaning
La figure 3 montre une vue analogue de celle de la figure 2 illustrant une variante de réalisation du picot de bouchage Selon cette réalisation, une capsule 103 comporte un couvercle 105 muni d'un picot 106 Ce picot a une section allongée, courbée en forme de « haricot » Il comporte un revêtement extérieur 172 en matériau élastomérique souple L'orifice correspondant 104 a une forme complémentaire, de sorte que le picot peut rentrer dans cet orifice à friction. La forme « haricot » de l'orifice 104 et du picot 106 n'est donnée qu'à titre d'exemple Selon l'invention, toute autre forme imaginable peut être envisagée La façon de réaliser la capsule conforme à l'invention, est d'une grande simplicité permettant de la fabriquer en un seul cycle de moulage de courte durée, par bi-injection successive des matériaux rigide et souple. Cette capsule peut alors être fabriquée à un prix de revient avantageux. Figure 3 shows a view similar to that of Figure 2 illustrating an alternative embodiment of the stopper pin. According to this embodiment, a capsule 103 has a cover 105 provided with a pin 106. This pin has an elongated section, curved in the shape of "Bean" It has an outer coating 172 made of flexible elastomeric material. The corresponding orifice 104 has a complementary shape, so that the pin can enter this friction orifice. The “bean” shape of the orifice 104 and the spike 106 is given only by way of example. According to the invention, any other conceivable shape can be envisaged. The way of producing the capsule according to the invention is very simple, making it possible to manufacture it in a single short-term molding cycle, by successive bi-injection of the rigid and flexible materials. This capsule can then be manufactured at an advantageous cost price.
