Description

Embout à clapet pour distributeur de produits cosmétiques liquides Valve cap for dispenser of liquid cosmetic products
La présente invention concerne un embout à clapet pour un distributeur de produit cosmétique liquide.The present invention relates to a valve tip for a liquid cosmetic product dispenser.
Plus précisément, l'invention s'applique à des distributeurs comprenant notamment, un réservoir et un piston interne actionné par déplacement d'une embase.More specifically, the invention applies to dispensers comprising in particular, a reservoir and an internal piston actuated by displacement of a base.
Ces distributeurs sont généralement équipés d'une valve ou clapet d'extrémité assurant conjointement l'étanchéité du réservoir et la délivrance du produit.These dispensers are generally equipped with an end valve or valve ensuring jointly the sealing of the reservoir and the delivery of the product.
La valve est souvent intégrée à un embout applicateur qui est réalisé soit d'une seule pièce avec le réservoir, soit sous forme rapportée.The valve is often integrated into an applicator tip which is produced either in one piece with the reservoir, or in attached form.
Dans les deux cas, lors de la phase de conditionnement du produit, il est nécessaire d'assurer l'échappement de l'air se trouvant, en fin d'assemblage, dans l'espace situé au-dessus de la surface libre du liquide.In both cases, during the product conditioning phase, it is necessary to ensure the escape of the air which is, at the end of assembly, in the space located above the free surface of the liquid. .
Cette opération qui est effectuée chez le fabricant de produit, doit être simple et facile à mettre en œuvre pour ne pas entraîner de surcoût de production et/ou des défauts de qualité.This operation, which is carried out at the manufacturer of the product, must be simple and easy to implement so as not to entail additional production costs and / or quality defects.
Par ailleurs, en phase de distribution du produit, la précision du dosage dépend étroitement de la sensibilité de la valve et de sa capacité à réagir en réponse aux surpressions générées par les déplacements du piston, même pour les faibles amplitudes correspondant aux petites doses.Furthermore, during the product distribution phase, the precision of the dosage depends closely on the sensitivity of the valve and its ability to react in response to the overpressures generated by the movements of the piston, even for small amplitudes corresponding to small doses.
L'étanchéité, quant à elle, repose sur la rapidité et la fiabilité du rappel des éléments mobiles de la valve vers leur position de repos. Toutes ces contraintes sont autant dé problèmes techniques que l'embout de l'invention se propose de résoudre.Sealing, for its part, is based on the speed and reliability of the return of the movable elements of the valve to their rest position. All these constraints are as many technical problems as the tip of the invention proposes to solve.
Cet objectif est atteint au moyen d'un embout caractérisé en ce qu'il comprend une coiffe fermant le réservoir et présentant un orifice de distribution qui est susceptible d'être obturé de manière étanche par un ergot solidaire d'une entretoise logée de manière coulissante à l'intérieur de la coiffe et pourvue d'au moins un conduit assurant successivement l'éventement du réservoir et l'évacuation du produit, ladite coiffe et ladite entretoise délimitant entre elles, une enceinte dont la paroi présente au moins une zone élastiquement déformable permettant de dégager l'ergot de l'orifice de distribution, suite à l'actionnement du piston, pour assurer la délivrance du produit.This objective is achieved by means of a nozzle characterized in that it comprises a cap closing the reservoir and having a dispensing orifice which is capable of being sealed in a sealed manner by a lug secured to a spacer housed in a sliding manner inside the cap and provided with at least one conduit successively ensuring the venting of the reservoir and the evacuation of the product, said cap and said spacer delimiting between them, an enclosure whose wall has at least one elastically deformable zone allowing to release the lug from the dispensing orifice, following the actuation of the piston, to ensure the delivery of the product.
Selon une première variante de réalisation, ladite zone déformable est portée par la partie supérieure de la coiffe, autour de l'orifice de distribution. De préférence, ledit conduit est alors réalisé au travers de l' entretoise.According to a first alternative embodiment, said deformable zone is carried by the upper part of the cap, around the dispensing orifice. Preferably, said conduit is then produced through the spacer.
Selon une autre variante, ladite zone déformable est constituée de la paroi supérieure d'une cellule de gaz, supportant ledit ergot. De préférence, ladite cellule est alors solidaire de ladite entretoise.According to another variant, said deformable zone consists of the upper wall of a gas cell, supporting said lug. Preferably, said cell is then secured to said spacer.
En outre, ledit conduit est ici réalisé sur le pourtour de ladite cellule.In addition, said conduit is here produced around the periphery of said cell.
Selon une caractéristique avantageuse, le pourtour inférieur de ladite entretoise est pourvu d'un organe de liaison avec le bord supérieur du réservoir.According to an advantageous characteristic, the lower periphery of said spacer is provided with a connecting member with the upper edge of the tank.
Selon une autre caractéristique, ladite coiffe comporte une jupe venant en serrage radial avec la paroi latérale externe du réservoir.According to another characteristic, said cap comprises a skirt coming in radial tightening with the external lateral wall of the reservoir.
Selon encore une autre caractéristique, ladite coiffe comporte une butée interne limitant le coulissement ascendant de l'entretoise lors de l'assemblage sur le réservoir. Un autre objet de l'invention est un procédé de conditionnement d'un produit cosmétique liquide dans un distributeur comprenant un embout selon l'invention, caractérisé en ce que, après remplissage, on emmanche ladite coiffe sur le réservoir avec l'entretoise interne en position basse pour dégager l'orifice de distribution, puis on appuie sur ledit embout en échappant l'air inclus vers l'extérieur, via le conduit, l'enceinte et l'orifice jusqu'à ce que l'entretoise vienne d'abord en butée, vers le bas contre le bord supérieur du réservoir puis, ensuite, la coiffe en butée contre l'entretoise, alors que l'ergot vient s'engager de manière étanche dans l'orifice de distribution.According to yet another characteristic, said cap has an internal stop limiting the upward sliding of the spacer during assembly on the tank. Another object of the invention is a method for packaging a liquid cosmetic product in a dispenser comprising a nozzle according to the invention, characterized in that, after filling, said cap is fitted onto the reservoir with the internal spacer in low position to clear the dispensing orifice, then press on said nozzle while escaping the included air to the outside, via the duct, the enclosure and the orifice until the spacer comes first in abutment, down against the upper edge of the tank and then, the cap abutting against the spacer, while the lug engages in a sealed manner in the dispensing orifice.
Selon une caractéristique du procédé, on guide l'embout sur le distributeur en faisant coulisser la coiffe sur la paroi latérale du réservoir offrant ainsi une portée radiale.According to a characteristic of the process, the end piece is guided on the dispenser by sliding the cap on the side wall of the reservoir, thus offering a radial reach.
L'embout de l'invention est particulièrement simple puisqu'il ne comprend que deux pièces (coiffe et entretoise) qui sont susceptibles de rester attachées l'une à l'autre, en formant un ensemble pré-assemblé, livré chez le client avec l'autre partie du distributeur (réservoir, piston et embase).The tip of the invention is particularly simple since it comprises only two parts (cap and spacer) which are capable of remaining attached to each other, forming a pre-assembled assembly, delivered to the customer with the other part of the distributor (tank, piston and base).
Le procédé de conditionnement de l'invention est, en outre, facile à industrialiser puisque l'étape finale de fermeture consiste en un simple emmanchement de l'ensemble pré-assemblé sur le réservoir avec échappement automatique de l'air inclus.The packaging method of the invention is, moreover, easy to industrialize since the final closing step consists of a simple fitting of the pre-assembled assembly onto the tank with automatic exhaust of the air included.
Au surplus, cet emmanchement est guidé grâce à la coopération entre la jupe de la coiffe- et la paroi du réservoir offrant une portée radiale.In addition, this fitting is guided by the cooperation between the skirt of the cap and the wall of the tank providing a radial reach.
L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels ;The invention will be better understood on reading the description which follows with reference to the drawings on which;
Les figures 1A et IB représentent des vues en coupe d'un premier mode de réalisation de l'embout de l'invention monté sur un distributeur, respectivement en phase de repos et en phase de distribution. Les figures 2A et 2B représentent des vues en coupe d'un second mode de réalisation de l'embout de l'invention monté sur un même distributeur, respectivement en phase de repos et en phase de distribution.Figures 1A and IB show sectional views of a first embodiment of the nozzle of the invention mounted on a distributor, respectively in the rest phase and in the distribution phase. Figures 2A and 2B show sectional views of a second embodiment of the nozzle of the invention mounted on the same distributor, respectively in the rest phase and in the distribution phase.
Les figures 3A à 3D représentent des vues schématiques des différentes étapes du procédé de conditionnement de l'invention.FIGS. 3A to 3D represent schematic views of the different stages of the packaging method of the invention.
Les modes de réalisation de l'embout de l'invention sont représentés sur les figures en association avec des distributeurs D de produits cosmétiques liquides dont la structure est ici présentée de façon schématique.The embodiments of the tip of the invention are shown in the figures in association with dispensers D of liquid cosmetic products, the structure of which is shown here diagrammatically.
Ces distributeurs D comprennent notamment et à titre principal, un réservoir R et un piston interne P déplacé par actionnement manuel d'une embase E, et ici, en particulier, par rotation de ladite embase autour d'un axe vertical, relativement au réservoir R et à l'embout.These distributors D include in particular and primarily, a reservoir R and an internal piston P moved by manual actuation of a base E, and here, in particular, by rotation of said base about a vertical axis, relative to the tank R and the tip.
Bien entendu, l'embout de l'invention est apte à être monté sur des distributeurs différents de ceux qui sont représentés ici, et notamment sur des distributeurs dont le piston est mû par déplacement axial de l'actionneur.Of course, the tip of the invention is capable of being mounted on distributors different from those which are represented here, and in particular on distributors whose piston is moved by axial displacement of the actuator.
Sur les figures 1A, IB, 2A et 2B, le produit n'est pas représenté pour des raisons de clarté.In FIGS. 1A, IB, 2A and 2B, the product is not shown for reasons of clarity.
L'embout de l'invention comprend une coiffe 1 fermant le réservoir R et présentant un orifice de distribution 10. L'orifice 10 est susceptible d'être obturé de manière étanche par un ergot ou pointeau 21 solidaire d'une entretoise 2 logée de manière coulissante à l'intérieur de la coiffe 1.The tip of the invention comprises a cap 1 closing the reservoir R and having a dispensing orifice 10. The orifice 10 is capable of being sealed in a sealed manner by a lug or needle 21 secured to a spacer 2 housed in sliding inside the cover 1.
L'entretoise 2 est pourvue d'au moins un conduit 20 assurant successivement l'éventement du réservoir R comme représenté sur les figures 3 A à 3D et l'évacuation du produit à partir dudit réservoir, comme sur les figures IB et 2B. La coiffe 1 et l'entretoise 2 délimitent entre elles, dans la partie supérieure de l'embout, une enceinte 12 alimentée en produit via le conduit 20. La paroi de cette enceinte présente au moins une zone élastiquement déformable permettant de dégager l'ergot 21 de l'orifice de distribution 10, sous l'action du piston P, pour permettre la délivrance du produit.The spacer 2 is provided with at least one conduit 20 successively ensuring the venting of the tank R as shown in Figures 3 A to 3D and the discharge of the product from said tank, as in Figures IB and 2B. The cap 1 and the spacer 2 delimit between them, in the upper part of the end piece, an enclosure 12 supplied with product via the conduit 20. The wall of this enclosure has at least one elastically deformable zone allowing the lug to be released. 21 of the dispensing orifice 10, under the action of the piston P, to allow the delivery of the product.
Le pourtour inférieur de l'entretoise 2 est pourvu d'un élément assurant la liaison avec le bord supérieur ou col r du réservoir R tandis que la coiffe 1 comporte une jupe 11 venant en serrage radial étanche avec la paroi latérale externe du réservoir R et en butée externe contre le bord supérieur de l'embase E.The lower periphery of the spacer 2 is provided with an element ensuring the connection with the upper edge or neck r of the reservoir R while the cap 1 comprises a skirt 11 coming in tight radial tightening with the external lateral wall of the reservoir R and in external abutment against the upper edge of the base E.
La coiffe .1 comporte également une butée interne, par exemple, sous forme d'un épaulement 13 destiné à limiter le coulissement relatif et ascendant de l'entretoise 2 lors du montage de l'embout sur un distributeur, comme représenté sur les figures 3C et 3D.The cover .1 also includes an internal stop, for example, in the form of a shoulder 13 intended to limit the relative and upward sliding of the spacer 2 during assembly of the end piece on a distributor, as shown in FIGS. 3C and 3D.
Dans le mode de réalisation des figures 1A et IB, la zone déformable de l'enceinte 12 est portée par la partie supérieure de la coiffe 1. Cette zone est formée par la paroi de la coiffe elle-même, qui est réalisée, au moins autour de l'orifice de distribution 10, avec un matériau et/ou une épaisseur déterminés, lui conférant une flexibilité suffisante pour libérer l'orifice 10 sous la pression du produit.In the embodiment of FIGS. 1A and 1B, the deformable zone of the enclosure 12 is carried by the upper part of the cap 1. This zone is formed by the wall of the cap itself, which is produced, at least around the dispensing orifice 10, with a determined material and / or thickness, giving it sufficient flexibility to release the orifice 10 under the pressure of the product.
Le conduit 20 est ici ménagé au travers de l'entretoise 2 et, dans la variante représentée, autour de l'ergot 21.The conduit 20 is here formed through the spacer 2 and, in the variant shown, around the lug 21.
Le réservoir R présente un col r dont le profil est complémentaire de celui de la collerette périphérique 22 de l'entretoise 2 assurant la liaison avec ledit col par emboîtement.The reservoir R has a neck r whose profile is complementary to that of the peripheral flange 22 of the spacer 2 ensuring the connection with said neck by interlocking.
Par. ailleurs, le profil de la face latérale de l'entretoise 2 épouse la paroi interne de la coiffe 1 au niveau de l'épaulement 13, assurant ainsi un calage en position haute. Dans le mode de réalisation des figures 2A et 2B, la zone déformable de l'enceinte 12 est constituée de la paroi supérieure 23a d'une cellule de gaz 24 supportant l'ergot 21.Through. elsewhere, the profile of the lateral face of the spacer 2 conforms to the internal wall of the cap 1 at the shoulder 13, thus ensuring wedging in the high position. In the embodiment of FIGS. 2A and 2B, the deformable zone of the enclosure 12 consists of the upper wall 23a of a gas cell 24 supporting the lug 21.
De préférence, le gaz utilisé sera de l'air sous pression atmosphérique.Preferably, the gas used will be air under atmospheric pressure.
La cellule 24 est hermétique et solidaire de l'entretoise 2.The cell 24 is hermetic and integral with the spacer 2.
Sous l'action du piston P, une surpression est générée dans le réservoir R et dans l'enceinte 12. La paroi de la coiffe 1 n'étant pas dans ce cas déformable, cette surpression est absorbée par la paroi mince de la cellule 24 formant membrane qui fléchit en entraînant avec elle l'ergot 21 et en libérant ainsi l'orifice 10.Under the action of the piston P, an overpressure is generated in the reservoir R and in the enclosure 12. The wall of the cover 1 not being deformable in this case, this overpressure is absorbed by the thin wall of the cell 24 forming a membrane which flexes, carrying with it the lug 21 and thereby freeing the orifice 10.
Bien entendu, ce fonctionnement n'est possible qu'à la condition que le différentiel de pression entre celle régnant dans l'enceinte 12 pressurisée par l'action du piston P, et celle du volume intérieur de la cellule 24, soit positif.Of course, this operation is only possible on condition that the pressure differential between that prevailing in the enclosure 12 pressurized by the action of the piston P, and that of the interior volume of the cell 24, is positive.
Dans la variante représentée, la cellule est logée à l'intérieur de l'entretoise et le fond 23b de la cellule est constitué d'une paroi rigide indéformable dans les conditions de pression qui sont susceptibles d'être établies.In the variant shown, the cell is housed inside the spacer and the bottom 23b of the cell consists of a rigid wall which cannot be deformed under the pressure conditions which are liable to be established.
Ce fond peut être rapporté, comme dans la variante représentée, ou réalisé d'une seule pièce avec les autres parties de la cellule 24.This bottom can be attached, as in the variant shown, or produced in one piece with the other parts of the cell 24.
Le conduit 20 est réalisé sur le pourtour de la cellule sous la forme d'au moins un canal 20a. S'il est prévu une pluralité de canaux, comme dans la variante représentée, ceux-ci seront séparés par des cloisons 25 qui s'étendent, axialement, entre la paroi latérale de la cellule 24 et la paroi de l'embout 1.The conduit 20 is produced on the periphery of the cell in the form of at least one channel 20a. If a plurality of channels is provided, as in the variant shown, these will be separated by partitions 25 which extend, axially, between the side wall of the cell 24 and the wall of the end piece 1.
Le col r du réservoir est formé d'au moins un créneau périphérique c assurant conjointement le passage du produit et la liaison avec l'entretoise 2. Le montage de l'embout de l'invention sur le distributeur D est une opération mise en œuvre pendant le procédé de conditionnement du produit qui s'effectue de la manière suivante :The neck r of the reservoir is formed of at least one peripheral slot c jointly ensuring the passage of the product and the connection with the spacer 2. The assembly of the end piece of the invention on the distributor D is an operation implemented during the product packaging process which is carried out as follows:
Après remplissage du réservoir R (figure 3 A), on positionne et on emmanche la coiffe 1 comme représenté sur la figure 3B.After filling the reservoir R (FIG. 3 A), the cap 1 is positioned and inserted as shown in FIG. 3B.
Dans cette étape, l'entretoise 2 est en position basse ; l'ergot 21 étant en retrait par rapport à l'orifice 10.In this step, the spacer 2 is in the low position; the lug 21 being set back relative to the orifice 10.
On appuie ensuite sur l'embout dans le . sens vertical, ce qui a pour effet de faire échapper l'air inclus vers l'extérieur (représenté par les flèches sur la figure 3B) de façon continue et automatique, via le conduit 20, l'enceinte 12 et l'orifice 10.We then press the tip into the . vertical direction, which has the effect of making the included air escape outside (represented by the arrows in FIG. 3B) continuously and automatically, via the conduit 20, the enclosure 12 and the orifice 10.
Au cours de cette première phase de l'assemblage, l'embout est guidé par coulissement extérieur de la coiffe 1 sur la paroi latérale du réservoir R offrant ainsi une portée radiale, tandis que l'entretoise 2 est fixe relativement à la coiffe 1.During this first phase of assembly, the endpiece is guided by external sliding of the cover 1 on the side wall of the tank R thus offering a radial reach, while the spacer 2 is fixed relative to the cover 1.
Cet emmanchement avec coulissement se poursuit jusqu'à ce que l'entretoise 2 vienne en butée vers le bas contre le bord supérieur r du réservoir R, comme représenté sur la figure 3C.This sliding fitting continues until the spacer 2 abuts down against the upper edge r of the tank R, as shown in FIG. 3C.
A partir de cette position, l'entretoise 2 est immobilisée sur le réservoir et seule la coiffe 1 continue de coulisser verticalement et relativement à l'ensemble entretoise/réservoir.From this position, the spacer 2 is immobilized on the reservoir and only the cap 1 continues to slide vertically and relative to the spacer / reservoir assembly.
L'assemblage est terminé lorsque l'ergot 21 vient s'engager de manière étanche dans l'orifice 10 et que la coiffe 1 vient conjointement en butée contre la partie supérieure de l'entretoise 2 ; le bord inférieur de la jupe 11 venant ici simultanément au contact de l'embase E, comme représenté sur la figure 3D. The assembly is completed when the lug 21 engages in a sealed manner in the orifice 10 and when the cover 1 comes jointly into abutment against the upper part of the spacer 2; the lower edge of the skirt 11 here coming simultaneously into contact with the base E, as shown in FIG. 3D.
