Description

DISPOSITIF D'OBTURATION POUR DISTRIBUTEUR DE PRODUIT LIQUIDE SANS REPRISE D'AIR SHUTTERING DEVICE FOR A LIQUID PRODUCT DISPENSER WITHOUT AIR INTAKE
La présente invention concerne un dispositif d'obturation pour distributeur de produit liquide sans reprise d'air.The present invention relates to a closure device for a liquid product dispenser without air intake.
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 distribution of cosmetic or pharmaceutical products from a rigid tank equipped in particular with means for withdrawing the product and from a movable 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, due to the absence of air, the bottom rises naturally 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 movable bottom ensures by sliding the static and dynamic sealing with the wall of the tank. The hermeticity of the distributor 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 leak.
La présente invention a pour but de résoudre ce problème technique de manière satisfaisante. 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.The object of the present invention is to solve this technical problem satisfactorily. This object is achieved by means of a device comprising an assembly consisting of a base forming a housing, 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 and wedging sleeve in which is engaged, in a sliding manner, an axial sleeve carried by the external 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 to the outside at 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 sleeve and said central sleeve have beveled lower and upper edges respectively, making it easier to guide one into the other by guidance.
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 outward 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 is connected to the periphery of said cap by a concave portion ensuring, by bracing on the internal wall of the cup or of the reservoir, 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 outwards by a ring, the upper and lower edges of which 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. Selon une autre variante, le diamètre intérieur de l'embase est légèrement supérieur au diamètre intérieur du réservoir.According to yet another characteristic, said base comprises latching elements cooperating with complementary elements carried by the base of the tank. 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 assembly offering good protection to the movable base during the delicate operations of storage at the outlet of the mold, of transfer to the assembly and assembly stations 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 movable 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 movable bottom and its exit from the base / box forming the fixed bottom then its passage in the tank, are carried out automatically by axial sliding in response to the vacuum created from the initial distribution phase.
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 reservoir is generally carried out in the reverse position of the distributor (upside down) then the integral base / movable bottom assembly is mounted on the open part of the reservoir in the manner of a cover before turning the distributor over to put it in a vertical position of storage and use in which the removal means are arranged at the top.
Toutes ces opérations sont effectuées sans contact avec le fond mobile qui reste enfermé dans l'embase.All these operations are carried out without contact with the movable base 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. L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels :If necessary, the commissioning will include an operation consisting in extracting the movable base from the base by exerting a slight axial thrust through the central bore of the sleeve, which also allows the residual air trapped in the tank after product packaging. The invention will be better understood on reading the description which follows with reference to the drawings in which:
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,FIG. 1 represents a view in axial section of an embodiment of the device of the invention before assembly on a tank and,
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.2 shows an axial sectional view of the device of Figure 1, after assembly on a tank and commissioning of the dispenser.
La figure 3 représente une vue en coupe d'un autre mode de réalisation de l'invention.Figure 3 shows 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 dispensers 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 notably equipped with a reservoir and means for withdrawing 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 produced 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 shown in FIGS. 1 and 2 seals the dispenser at the bottom and rises by sliding inside the reservoir R (FIG. 2) under the effect of the internal depression following the exit of the successive doses of product that are issued.
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. La lèvre 12 se raccorde au pourtour de la calotte 11 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.In the variant of FIGS. 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 outward and which also provides , the scraping of the internal wall of the tank R when the bottom moves between two rest positions. The lip 12 is connected to the periphery of the cap 11 of the bottom by a concave portion 120 ensuring, by bracing on the internal 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 Figure 3, the bottom 1 consists of a cup 13 extended laterally outward 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 previous figures.
Ces lèvres, qui sont généralement réalisées avec un matériau elastomère, 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 with an elastomeric material, are fragile, in particular at their thinned end which is intended to come into bearing contact, under slight stress, against the internal wall of the reservoir.
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, provision is made, according to the invention, to place the base 1, as soon as it is manufactured, 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.To this end, 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, produced here in the form of slots, cooperating with complementary elements r carried by the base of tank R.
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 awaiting its mounting on the tank R as shown in FIG. 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. Dans la variante représentée, la douille 10 est creuse.The base 2 has a central sleeve 20 opening to the outside by forming a duct for the entry of air into the space between the base 1 and the base and in which is slidably engaged a socket axial 10 carried by the outer face of the bottom 1, located here below. 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 10a 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 sleeve 10 and the sleeve 20 ensures the retention and the setting of the bottom 1 and guarantees a correct stop and positioning relative to the reservoir R with a view to its subsequent travel. The lower edge 10a of the sleeve 10 and, here, also the upper edge 20a of the sleeve 20, are profiled in a bevel to facilitate by guiding, their mutual engagement and the nesting of one in 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 in Figure 2, the base 2 is fitted inside the reservoir 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 reservoir 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 internal wall of the reservoir R is provided with a slope P facilitating the forced or automatic sliding of the lip 12 at the internal 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 for the base to be fitted outside the tank, the wall of the tank then being inserted between the lip of the movable bottom and the skirt of the base.
