Description

La présente invention concerne un dispositif d'obturation pour distributeur de produit liquide sans reprise d'air ( EP 0 099 457 A ).The present invention relates to a closure device for liquid product dispenser without air intake ( EP 0 099 457 A ).

L'invention s'applique plus particulièrement à la distribution de produits cosmétiques ou pharmaceutiques à partir d'un réservoir rigide équipé notamment de moyens de prélèvement du produit et d'un fond mobile pourvu de moyens d'étanchéité.The invention applies more particularly to the dispensing of cosmetic or pharmaceutical products from a rigid reservoir equipped in particular with means for sampling the product and a moving bottom provided with sealing means.

Au fur et à mesure que le consommateur prélève du produit, le volume interne du réservoir se réduit et, du fait de l'absence d'air, le fond remonte naturellement pour compenser le vide ainsi crée,As the consumer takes the product, the internal volume of the tank is reduced and, because of the absence of air, the bottom naturally rises to compensate for the vacuum thus created,

Ce fond mobile assure par coulissement l'étanchéité statique et dynamique avec la paroi du réservoir. L'herméticité du distributeur et le bon conditionnement du produit dépendent étroitement de la fiabilité des moyens d'étanchéité du fond.This mobile bottom slidably ensures static and dynamic sealing with the tank wall. The hermeticity of the dispenser and the good packaging of the product depend closely on the reliability of the bottom sealing means.

Par conséquent, ces moyens d'étanchéité qui sont réalisés par moulage d'une paroi mince avec une matière souple, déformable et fragile doivent donc être protégés dès leur sortie du moule et jusqu'au montage du fond dans le réservoir pour éviter tout risque de fuite ultérieure.Consequently, these sealing means which are produced by molding a thin wall with a flexible, deformable and fragile material must therefore be protected as soon as they leave the mold and until the bottom is mounted in the tank to avoid any risk of subsequent leakage.

La présente invention a pour but de résoudre ce problème technique de manière satisfaisante.The present invention aims to solve this technical problem satisfactorily.

Ce but est atteint au moyen d'un dispositif comprenant un ensemble constitué d'une embase formant boîtier, destinée à être fixée à la base dudit réservoir et à l'intérieur de laquelle est destiné à être logé intégralement et coaxialement ledit fond, dès sa fabrication et avant distribution du produit de façon à protéger lesdits moyens d'étanchéité.This object is achieved by means of a device comprising an assembly consisting of a housing base, intended to be fixed to the base of said tank and inside which is intended to be housed integrally and coaxially said bottom, from its manufacture and before distribution of the product so as to protect said sealing means.

Selon une caractéristique avantageuse, ladite embase présente un manchon central de retenue et de calage dans lequel est engagée, de manière coulissante, une douille axiale portée par la face extérieure du fond mobile.According to an advantageous characteristic, said base has a central retaining sleeve and wedging in which is engaged, in a sliding manner, an axial sleeve carried by the outer face of the movable bottom.

Selon une autre caractéristique, ledit manchon débouche à l'extérieur à la partie inférieure de ladite embase.According to another characteristic, said sleeve opens outwards to the lower part of said base.

Ladite douille et ledit manchon central présentent des bords respectivement inférieur et supérieur biseautés facilitant, par guidage, l'emboîtement de l'un dans l'autre.Said bushing and said central sleeve have edges respectively lower and upper bevelled facilitating, by guiding, the interlocking of one into the other.

Selon une première variante, ledit fond est constitué d'une calotte prolongée latéralement vers l'extérieur par une lèvre d'étanchéité périphérique.According to a first variant, said bottom consists of a cap extended laterally outwards by a peripheral sealing lip.

De préférence, ladite lèvre se raccorde au pourtour de ladite calotte par une portion concave assurant, par arc-boutement sur la paroi interne de la coupelle ou du réservoir, un blocage anti-retour du fond.Preferably, said lip connects to the periphery of said cap by a concave portion ensuring, by abutment on the inner wall of the cup or tank, a non-return blocking of the bottom.

Selon une autre variante, ledit fond est constitué d'une coupelle prolongée latéralement vers l'extérieur par une bague dont les bords supérieur et inférieur sont pourvus chacun d'une lèvre d'étanchéité périphérique.According to another variant, said bottom consists of a cup extended laterally outwardly by a ring whose upper and lower edges are each provided with a peripheral sealing lip.

Selon encore une autre caractéristique, ladite embase comporte des éléments d'encliquetage coopérant avec des éléments complémentaires portés par la base du réservoir.According to yet another characteristic, said base comprises latching elements cooperating with complementary elements carried by the base of the tank.

Selon une autre variante, le diamètre intérieur de l'embase est légèrement supérieur au diamètre intérieur du réservoir.According to another variant, the inside diameter of the base is slightly greater than the inside diameter of the tank.

Le dispositif de l'invention comprend donc un ensemble prêt au montage offrant une bonne protection au fond mobile durant les opérations délicates de stockage en sortie de moule, de transfert vers les postes d'assemblage et de montage sur le réservoir.The device of the invention therefore comprises an assembly ready for mounting providing good protection to the moving bottom during delicate operations storage mold output, transfer to the assembling stations and mounting on the tank.

Cet ensemble constitue ainsi un double fond avec une pièce extérieure fixe formant à la fois embase pour le réservoir et boîtier pour la pièce intérieure formant fond mobile.This assembly thus constitutes a double bottom with a fixed outer part forming both a base for the tank and a housing for the inner part forming a moving bottom.

La séparation du fond mobile et sa sortie de l'embase/boîtier formant le fond fixe puis son passage dans le réservoir, s'effectuent automatiquement par coulissement axial en réponse à la dépression créée dès la phase initiale de distribution.The separation of the mobile bottom and its output from the base / housing forming the fixed bottom and its passage in the tank, are carried out automatically by axial sliding in response to the depression created from the initial phase of distribution.

Le remplissage du réservoir est généralement effectué en position inversée du distributeur (tête en bas) puis l'ensemble solidaire embase/fond mobile est monté sur la partie ouverte du réservoir à la manière d'un couvercle avant de retourner le distributeur pour le mettre dans une position verticale de stockage et d'utilisation dans laquelle les moyens de prélèvement sont disposés à la partie supérieure.The filling of the tank is generally carried out in the inverted position of the distributor (head down) and then the integral fixed base / moving bottom is mounted on the open part of the tank in the manner of a lid before returning the dispenser to put it in a vertical storage and use position in which the sampling means are arranged at the upper part.

Toutes ces opérations sont effectuées sans contact avec le fond mobile qui reste enfermé dans l'embase.All these operations are performed without contact with the moving bottom which remains enclosed in the base.

Le cas échéant, la mise en service comportera une opération consistant à extraire le fond mobile de l'embase en exerçant une légère poussée axiale au travers de l'alésage central du manchon, ce qui permet également de chasser l'air résiduel enfermé dans le réservoir après conditionnement du produit.If necessary, the commissioning will include an operation of extracting the movable bottom of the base by exerting a slight axial thrust through the central bore of the sleeve, which also allows to drive the residual air enclosed in the tank after product conditioning.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels :

  • La figure 1 représente une vue en coupe axiale d'un mode de réalisation du dispositif de l'invention avant assemblage sur un réservoir et,
  • La figure 2 représente une vue en coupe axiale du dispositif de la figure 1, après assemblage sur un réservoir et mise en service du distributeur.
  • La figure 3 représente une vue en coupe d'un autre mode de réalisation de l'invention.
The invention will be better understood on reading the description which follows with reference to the drawings in which:
  • The figure 1 represents an axial sectional view of an embodiment of the device of the invention before assembly on a tank and,
  • The figure 2 represents an axial sectional view of the device of the figure 1 , after assembly on a tank and commissioning of the dispenser.
  • The figure 3 is a sectional view of another embodiment of the invention.

Le dispositif représenté sur les figures est destiné à être monté sur des distributeurs de produits liquides ou semi-liquides fonctionnant sans reprise d'air et appelés parfois «airless».The device shown in the figures is intended to be mounted on distributors of liquid or semi-liquid products operating without air intake and sometimes called "airless".

Ce type de distributeur est notamment équipé d'un réservoir et de moyens de prélèvement du produit tels qu'une pompe (non représentée).This type of dispenser is in particular equipped with a reservoir and means for taking the product such as a pump (not shown).

Le réservoir est réalisé dans le cadre de la présente invention, sous forme d'un conteneur rigide R comportant un fond mobile 1.The reservoir is made in the context of the present invention, in the form of a rigid container R comprising a movable bottom 1.

Le fond 1 représenté sur les figures 1 et 2 assure l'étanchéité du distributeur en partie basse et remonte en coulissant à l'intérieur du réservoir R (figure 2) sous l'effet de la dépression interne consécutive à la sortie des doses successives de produit qui sont délivrées.The bottom 1 represented on the Figures 1 and 2 ensures the tightness of the distributor in the lower part and goes up by sliding inside the tank R ( figure 2 ) under the effect of the internal depression following the output of the successive doses of product that are delivered.

Dans la variante des figures 1 et 2, le fond 1 est constitué d'une calotte 11 et possède des moyens d'étanchéité sous forme d'une lèvre périphérique 12 prolongeant la calotte 11 latéralement et vers l'extérieur et qui assure, en outre, le raclage de la paroi interne du réservoir R lors du déplacement du fond entre deux positions de repos.In the variant of Figures 1 and 2 , the bottom 1 consists of a cap 11 and has sealing means in the form of a peripheral lip 12 extending the cap 11 laterally and outwardly and which further ensures the scraping of the inner wall of the reservoir R when moving the bottom between two rest positions.

La lèvre 12 se raccorde au pourtour de la calotte I du fond par une portion concave 120 assurant, par arc-boutement sur la paroi interne du réservoir R, un blocage directionnel du fond mobile 1 vers le bas et/ou vers l'extérieur.The lip 12 is connected to the periphery of the cap I of the bottom by a concave portion 120 ensuring, by buttresses on the inner wall of the tank R, a directional blocking of the movable bottom 1 downwards and / or outwards.

Dans la variante de la figure 3, le fond 1 est constitué d'une coupelle 13 prolongée latéralement vers l'extérieur par une bague 14 dont les bords supérieur et inférieur sont pourvus chacun d'une lèvre d'étanchéité périphérique 12a, 12b dont la structure est analogue à celle de la lèvre 12 de la variante des figures précédentes.In the variant of the figure 3 , the bottom 1 consists of a cup 13 extended laterally outwards by a ring 14 whose upper and lower edges are each provided with a peripheral sealing lip 12a, 12b whose structure is similar to that of the lip 12 of the variant of the preceding figures.

Ces lèvres, qui sont généralement réalisées avec un matériau élastomère, sont fragiles, en particulier au niveau de leur extrémité amincie qui est destinée à venir en contact d'appui, sous légère contrainte, contre la paroi interne du réservoir.These lips, which are generally made of an elastomeric material, are fragile, in particular at their thinned end which is intended to come into bearing contact, under slight stress, against the inner wall of the tank.

Pour les protéger, il est prévu, selon l'invention, de placer le fond 1, dès sa fabrication, dans une embase 2 formant boîtier qui est destiné à être fixée à la base du réservoir R, immédiatement après son remplissage.To protect them, it is provided, according to the invention, to place the bottom 1, from its manufacture, in a base 2 forming a housing which is intended to be fixed to the base of the tank R immediately after filling.

A cet effet, l'embase 2 présente une jupe latérale 21 dont la hauteur est supérieure ou égale à celle du fond 1 et comporte des éléments d'encliquetage 22, réalisés ici sous forme de créneaux, coopérant avec des éléments complémentaires r portés par la base du réservoir R.For this purpose, the base 2 has a side skirt 21 whose height is greater than or equal to that of the bottom 1 and comprises snap-fastening elements 22, made here in the form of crenellations, cooperating with complementary elements r carried by the R tank base.

Le fond 1 est reçu et logé intégralement et coaxialement dans l'embase 2 en attendant son montage sur le réservoir R comme représenté sur la figure 1.The bottom 1 is received and housed integrally and coaxially in the base 2 while waiting for its mounting on the tank R as shown in FIG. figure 1 .

L'embase 2 présente un manchon central 20 débouchant à l'extérieur en formant un conduit pour l'entrée d'air dans l'espace compris entre le fond 1 et l'embase et dans lequel est engagée, de manière coulissante, une douille axiale 10 portée par la face extérieure du fond 1, située ici en dessous.The base 2 has a central sleeve 20 opening outwardly forming a duct for the entry of air into the space between the bottom 1 and the base and in which is engaged, in a sliding manner, a socket axial 10 carried by the outer face of the bottom 1, located here below.

Dans la variante représentée, la douille 10 est creuse.In the variant shown, the sleeve 10 is hollow.

La coopération entre la douille 10 et le manchon 20 assure la retenue et le calage du fond 1 et garantit une butée et un positionnement corrects relativement au réservoir R en vue de sa course ultérieure. Le bord inférieur l0a de la douille 10 et, ici, également le bord supérieur 20a du manchon 20, sont profilés en biseau pour faciliter par guidage, leur engagement mutuel et l'emboîtement de l'un dans l'autre.The cooperation between the bushing 10 and the sleeve 20 ensures the retention and the wedging of the bottom 1 and ensures a correct stop and positioning relative to the tank R for its subsequent race. The lower edge 10a of the sleeve 10 and here also the upper edge 20a of the sleeve 20, are beveled to facilitate guiding, their mutual engagement and the interlocking of one into the other.

Dans le mode de réalisation représenté sur la figure 2, l'embase 2 est emmanchée à l'intérieur du réservoir R.In the embodiment shown on the figure 2 , the base 2 is fitted inside the tank R.

Toutefois, le diamètre intérieur de l'embase 2 est légèrement supérieur au diamètre intérieur du réservoir R.However, the inside diameter of the base 2 is slightly greater than the inside diameter of the tank R.

Dans ces conditions, la partie basse de la paroi interne du réservoir R est munie d'une pente P facilitant le glissement forcé ou automatique de la lèvre 12 à la jonction intérieure entre le haut de la jupe 21 de l'embase 2 et le réservoir R.Under these conditions, the lower part of the inner wall of the tank R is provided with a slope P facilitating the forced or automatic sliding of the lip 12 at the inner junction between the top of the skirt 21 of the base 2 and the reservoir R.

Il serait néanmoins possible de prévoir que l'embase soit emmanchée à l'extérieur du réservoir, la paroi du réservoir s'intercalant alors entre la lèvre du fond mobile et la jupe de l'embase.It would nevertheless be possible to provide that the base is fitted to the outside of the tank, the wall of the tank then being interposed between the lip of the movable bottom and the skirt of the base.
