Description

La présente invention est relative aux distributeurs de produits liquides.The present invention relates to distributors of liquid products.

Plus particulièrement, l'invention concerne un distributeur de produit liquide, comprenant :

  • un réservoir adapté pour contenir du produit liquide (plus ou moins visqueux) et s'étendant selon une direction longitudinale entre des première et deuxième extrémités,
  • une tête distributrice montée à la deuxième extrémité du réservoir, cette tête distributrice comportant une buse de sortie actionnable selon la direction longitudinale pour distribuer du produit liquide,
  • une coque externe dans laquelle le réservoir est monté coulissant axialement selon la direction longitudinale,
  • une pièce d'entraînement montée en rotation par rapport à la coque externe et adaptée pour déplacer axialement le réservoir entre une position de stockage où la buse de sortie est escamotée dans la coque externe, et une position d'utilisation où la buse de sortie est au moins partiellement sortie de la coque externe.
More particularly, the invention relates to a liquid product dispenser, comprising:
  • a reservoir adapted to contain liquid product (more or less viscous) and extending in a longitudinal direction between first and second ends,
  • a dispensing head mounted at the second end of the tank, this dispensing head having an outlet nozzle operable in the longitudinal direction to dispense liquid product,
  • an outer shell in which the reservoir is mounted to slide axially in the longitudinal direction,
  • a drive member rotatably mounted relative to the outer shell and adapted to axially move the reservoir between a storage position where the outlet nozzle is retracted into the outer shell, and a use position where the outlet nozzle is at least partially out of the outer shell.

Le document EP-B-1 954 596 décrit un exemple d'un tels distributeur, qui présente notamment les inconvénients que d'une part, la direction d'émission du produit par la buse de sortie peut être mal maîtrisée par l'utilisateur, et d'autre part, l'utilisateur peut mettre les doigts devant la buse de sortie du produit en gênant ainsi la distribution de produit.The document EP-B-1 954 596 describes an example of such a distributor, which has the disadvantages that on the one hand, the direction of emission of the product by the outlet nozzle can be poorly controlled by the user, and secondly, the user can put fingers in front of the outlet nozzle of the product thus hindering the dispensing of product.

La présente invention a notamment pour but de pallier ces inconvénients.The present invention is intended to overcome these disadvantages.

A cet effet, selon l'invention, un distributeur du genre en question est caractérisé en ce que la buse de sortie présente une sortie orientée selon la direction longitudinale et est adaptée pour venir en butée axiale contre une partie solidaire de la coque externe lors d'un actionnement de la tête distributrice en position d'utilisation du distributeur,
en ce que la première extrémité du réservoir est reliée à un poussoir par un mécanisme d'entraînement adapté pour sélectivement escamoter le poussoir et la buse de sortie dans la coque externe en position de stockage et faire sortir axialement ledit poussoir et la buse de sortie de la coque externe en position d'utilisation.For this purpose, according to the invention, a distributor of the kind in question is characterized in that the outlet nozzle has an output oriented in the longitudinal direction and is adapted to come into axial abutment. against an integral part of the outer shell during an actuation of the dispensing head in the use position of the dispenser,
in that the first end of the tank is connected to a pusher by a drive mechanism adapted to selectively retract the pusher and the outlet nozzle into the outer shell in the storage position and axially remove said pusher and the outlet nozzle from the outer shell in the use position.

Grâce à ces dispositions, le distributeur s'actionne à la manière d'un stylo par appui sur le poussoir à l'opposé de la buse de distribution, ce qui d'une part, permet à l'utilisateur d'orienter très précisément la distribution de produit liquide, et d'autre part évite généralement que l'utilisateur mette ses doigts devant la buse de sortie.With these provisions, the dispenser is actuated in the manner of a pen by pressing the pusher opposite the dispensing nozzle, which on the one hand, allows the user to orient very precisely the dispensing liquid product, and secondly generally avoids the user putting his fingers in front of the outlet nozzle.

Dans divers modes de réalisation du distributeur selon l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • la première extrémité du réservoir est solidaire d'une pièce de commande annulaire centrée sur la direction longitudinale, qui comporte au moins une rainure hélicoïdale dans laquelle est monté coulissant au moins un pion solidaire du poussoir, ladite pièce de commande étant montée coulissante axialement et immobilisée en rotation par rapport à la coque externe, et le poussoir étant solidarisé en rotation par rapport à la pièce d'entraînement et monté coulissant axialement par rapport à la pièce d'entraînement et par rapport à la coque externe, ledit poussoir étant adapté pour buter axialement contre une partie de la coque externe en position d'utilisation ;
  • le mécanisme d'entraînement comporte en outre un coussinet annulaire qui est solidaire de la coque externe et qui coopère avec la pièce d'entraînement pour limiter le débattement angulaire de ladite pièce d'entraînement par rapport à la coque externe ;
  • le réservoir contient un parfum ou une composition cosmétique de soin et/ou de maquillage, en particulier sous forme d'une émulsion ou d'un gel.
In various embodiments of the dispenser according to the invention, one or more of the following provisions may also be used:
  • the first end of the reservoir is integral with an annular control part centered on the longitudinal direction, which comprises at least one helical groove in which is slidably mounted at least one pin integral with the pusher, said control part being slidably mounted axially and immobilized in rotation relative to the outer shell, and the pusher being secured in rotation relative to the drive part and slidably mounted axially with respect to the drive part and with respect to the outer shell, said pusher being adapted to abut axially against a portion of the outer shell in the use position;
  • the drive mechanism further comprises an annular bushing which is integral with the outer shell and which cooperates with the drive part to limit the angular displacement of said drive part relative to the outer shell;
  • the reservoir contains a perfume or a cosmetic care and / or makeup composition, in particular in the form of an emulsion or a gel.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description suivante d'une de ses formes de réalisation, donnée à titre d'exemple non limitatif, en regard des dessins joints.Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.

  • a first endpiece 6 which is rotatably mounted on the end 5a of the central body 5 so as to be rotatable about the longitudinal direction X between the storage position and the position of use, this first endpiece 6 having a circular opening 6a which is open in the longitudinal direction X opposite the central body 5 and in which is retracted the pusher 2 in the storage position,
  • a second endpiece 7 which is secured to the end 5b of the central body 5 by interlocking (single interlocking force, or interlocking completed by a bonding or welding), this second endpiece also comprising a circular opening 7a which is open in the longitudinal direction X away from the main body 5 and in which is retracted the nozzle 3 in the storage position.

Le corps central 5 contient un réservoir de produit 8 de forme général cylindrique, s'étendant selon la direction longitudinale X entre une extrémité 8a proche du premier embout 6 et une extrémité 8b proche du deuxième embout 7. Ce réservoir de produit 8 est rempli de produit liquide P à distribuer, ce produit liquide pouvant le cas échéant être plus ou moins visqueux. Le produit liquide en question peut être un parfum, un produit cosmétique de soin et/ou de maquillage, en particulier sous forme d'une émulsion ou d'un gel, un produit pharmaceutique ou autre.The central body 5 contains a product reservoir 8 of generally cylindrical shape, extending in the longitudinal direction X between an end 8a close to the first endpiece 6 and an end 8b close to the second endpiece 7. This product reservoir 8 is filled with liquid product P to be dispensed, this liquid product may optionally be more or less viscous. The liquid product in question may be a perfume, a cosmetic care product and / or make-up, in particular in the form of an emulsion or a gel, a pharmaceutical product or the like.

Dans l'exemple considéré ici, l'extrémité 8a du réservoir 8 est ouverte, tandis que l'extrémité 8b du réservoir se prolonge par un col 8c sur lequel est montée une tête distributrice 9 telle qu'une pompe manuelle ou similaire.In the example considered here, the end 8a of the tank 8 is open, while the end 8b of the tank is extended by a neck 8c on which is mounted a dispensing head 9 such as a hand pump or the like.

Cette tête distributrice 9 comporte (voir la figure 2) :

  • un corps 9a qui est solidarisé avec le col 8c du réservoir par exemple au moyen d'une bague de fixation 10 clipsée sur le col 8c, ou par tout autre moyen,
  • et une tige d'actionnement 9b montée coulissante dans le corps 9a selon la direction longitudinale X, cette tige d'actionnement 9b étant creuse et étant emboîtée dans la buse de sortie 3 du distributeur, laquelle buse de sortie comporte au moins un canal 3a débouchant axialement et communiquant avec la tige d'actionnement 9b pour permettre la sortie du produit P lors de l'actionnement du distributeur, comme il sera expliqué ci-après.
This dispensing head 9 has (see figure 2 ):
  • a body 9a which is secured to the neck 8c of the reservoir for example by means of a fixing ring 10 clipped on the neck 8c, or by any other means,
  • and an actuating rod 9b slidably mounted in the body 9a in the longitudinal direction X, this actuating rod 9b being hollow and being fitted into the outlet nozzle 3 of the distributor, which outlet nozzle comprises at least one channel 3a opening axially and communicating with the actuating rod 9b to allow the output of the product P when actuating the dispenser, as will be explained below.

Dans le cas présent, le réservoir 8 est en outre fermé par un piston 11 monté coulissant à l'intérieur du réservoir selon la direction X pour délimiter un volume fermé rempli du produit liquide P. Dans le cas présent, la tête distributrice 9 fonctionne sans reprise d'air, c'est-à-dire sans laisser rentrer d'air dans le réservoir de produit 8 au fur et à mesure que le produit liquide P est distribué, de sorte que le piston 11 se déplace vers la deuxième extrémité 8b du réservoir au fur et à mesure de la consommation du produit liquide P.In this case, the tank 8 is further closed by a piston 11 slidably mounted inside the tank in the direction X to delimit a volume closed closed liquid product P. In this case, the dispensing head 9 operates without air intake, that is to say without letting air in the product tank 8 as the product liquid P is distributed, so that the piston 11 moves towards the second end 8b of the reservoir as and when consuming the liquid product P.

En alternative, le réservoir de produit 8 pourrait être sous pression et la tête distributrice 9 une soupape. A titre d'exemple, on pourra dans le cas d'un réservoir sous pression utiliser comme produit P un produit cosmétique de maquillage tel qu'un fond de teint.Alternatively, the product tank 8 could be under pressure and the dispensing head 9 a valve. By way of example, in the case of a pressure vessel, it is possible to use as product P a cosmetic makeup product such as a foundation.

Le premier embout 6 contient en outre un mécanisme de commande 12, bien visible sur les figures 2, 3, 3A, 4, 4A et 5 à 7, ce mécanisme de commande comportant notamment une pièce d'entraînement 13, un coussinet 14 et une pièce de commande 15.The first endpiece 6 also contains a control mechanism 12, clearly visible on the figures 2 , 3 , 3A , 4 , 4A and 5 to 7 , this control mechanism comprising in particular a driving part 13, a bearing 14 and a control part 15.

La pièce d'entraînement 13 présente une forme annulaire centrée sur la direction X. Cette pièce d'entraînement 13 est retenue axialement dans le premier embout 6, par exemple par clipsage d'une collerette 13a de cette pièce d'entraînement sur un jonc interne 6b du premier embout (voir la figure 2), et ladite pièce d'entraînement est également solidarisée en rotation avec le premier embout 6, par exemple par emboîtement de nervures axiales 6d du premier embout dans des encoches axiales 13b de la pièce d'entraînement (voir les figures 3A et 5).The drive part 13 has an annular shape centered on the direction X. This drive part 13 is retained axially in the first endpiece 6, for example by clipping a flange 13a of this drive part on an inner ring 6b of the first mouthpiece (see figure 2 ), and said drive part is also secured in rotation with the first endpiece 6, for example by interlocking axial ribs 6d of the first endpiece in axial notches 13b of the drive part (see FIGS. Figures 3A and 5 ).

De plus, comme représenté notamment sur les figures 4A et 5, la pièce d'entraînement 13 est solidarisée en rotation avec le poussoir 2, par exemple au moyen de nervures axiales internes 13c (ou autres reliefs) de la pièce de commande 13, qui s'étendent selon la direction X et pénètrent dans des rainures axiales 2b formées à l'extérieur d'une jupe axiale 2a qui appartient au poussoir 2 et qui s'étend selon la direction X vers le réservoir 8 en traversant la pièce d'entraînement. Le poussoir 2 n'est en revanche pas lié axialement à la pièce d'entraînement, de sorte qu'il peut se déplacer axialement selon la direction X par rapport à la pièce d'entraînement 13, comme il sera expliqué ci-après.Moreover, as represented in particular on Figures 4A and 5 , the driving part 13 is secured in rotation with the pusher 2, for example by means of internal axial ribs 13c (or other reliefs) of the control part 13, which extend in the direction X and penetrate into grooves 2b formed outside of an axial skirt 2a which belongs to the pusher 2 and which extends in the direction X towards the tank 8 crossing the workpiece. The pusher 2 is however not axially connected to the drive part, so that it can move axially in the direction X relative to the drive part 13, as will be explained below.

Le coussinet 14, quant à lui, est également une pièce annulaire centrée sur la direction X, qui est disposée autour de la pièce d'entraînement 13. Comme on peut le voir notamment sur les figures 3A et 6, le coussinet 14 est relié à la pièce d'entraînement 13 de façon à permettre un mouvement de rotation de ladite pièce de commande 13 avec le premier embout 6 selon un angle de débattement limité. La limitation de cet angle de débattement peut être obtenue par tout moyen connu, par exemple par deux pions 14a formés à l'intérieur du coussinet 14, qui coopèrent par butée avec deux dents 13d de la pièce d'entraînement, dents qui s'étendent axialement vers le réservoir 8. L'angle de débattement autorisé pour la pièce d'entraînement et le premier embout 6, entre la position de stockage et la position d'utilisation, peut ainsi être par exemple de l'ordre d'un tiers de tour.The pad 14, meanwhile, is also an annular piece centered on the X direction, which is arranged around the drive piece 13. As can be seen in particular on the Figures 3A and 6 , the pad 14 is connected to the drive part 13 so as to allow a rotational movement of said control member 13 with the first nozzle 6 at a limited deflection angle. The limitation of this deflection angle can be obtained by any known means, for example by two pins 14a formed inside the bearing 14, which cooperate by abutment with two teeth 13d of the drive part, teeth which extend axially towards the reservoir 8. The authorized clearance angle for the drive part and the first endpiece 6, between the storage position and the position of use, can thus be for example of the order of one third of tower.

Des moyens d'indexation peuvent également être prévus pour retenir la pièce de commande 13 et le premier embout 6, soit dans la position de stockage, soit dans la position d'utilisation. Dans l'exemple représenté, ces moyens d'indexation peuvent comprendre notamment deux bossages 13e faisant saillie respectivement à l'extérieur des deux dents 13d de la pièce de commande, ces bossages pénétrant dans des évidements internes 14b du coussinet 14, respectivement dans la position de repos et dans la position d'utilisation.Indexing means may also be provided to retain the control part 13 and the first end piece 6, either in the storage position or in the position of use. In the example shown, these indexing means may comprise in particular two bosses 13e projecting respectively outside the two teeth 13d of the control part, these bosses penetrating into internal recesses 14b of the pad 14, respectively in the position resting and in the position of use.

Comme représenté notamment sur les figures 2, 3A, 4 et 7, le coussinet 14 est en outre solidarisé avec un col 16 formé à l'extrémité 5a du corps 5 :

  • axialement, par clipsage du col 16 dans le coussinet 14,
  • et en rotation, par exemple par engagement de nervures axiales externes 16a du col 16, dans des rainures axiales internes 14c du coussinet.
As represented in particular on figures 2 , 3A , 4 and 7 the pad 14 is furthermore secured with a neck 16 formed at the end 5a of the body 5:
  • axially, by clipping the neck 16 into the pad 14,
  • and in rotation, for example by engagement of external axial ribs 16a of the neck 16, in internal axial grooves 14c of the pad.

Comme on peut le voir notamment sur les figures 2, 3, 3A, 4, 4A et 7, la pièce de commande 15 est une pièce annulaire centrée sur la direction X, disposée autour de la jupe 2a du poussoir 2 et solidarisée par clipsage ou autre avec l'extrémité 8a du réservoir 8.As can be seen in particular on figures 2 , 3 , 3A , 4 , 4A and 7 , the control part 15 is an annular piece centered on the direction X, arranged around the skirt 2a of the pusher 2 and secured by clipping or otherwise with the end 8a of the tank 8.

Cette pièce de commande 15 possède deux rainures hélicoïdales 15a dans lesquelles pénètrent des pions externes 2c formés à l'extrémité libre de la jupe 2a du poussoir 2. Le poussoir 2 possède en outre un bord inférieur 2d en forme de double rampe hélicoïdale glissant sur deux rainures hélicoïdales internes 15c de la pièce de commande 15, complétant ainsi de manière optionnelle et/ou alternative le guidage du poussoir 2 par rapport à la pièce de commande 15. La pièce de commande est en outre solidarisée en rotation avec le corps principal 5, par exemple au moyen de pions ou nervures 16b internes du col 16, qui pénètrent dans des rainures axiales externes 15b de la pièce de commande 15.This control part 15 has two helical grooves 15a into which external pins 2c formed at the free end of the skirt 2a of the pusher 2 penetrate. The pusher 2 also has a lower edge 2d in the form of a double helical ramp sliding on two internal helical grooves 15c of the control part 15, thus optionally and / or alternatively supplementing the guiding of the pusher 2 with respect to the control part 15. The control part is furthermore secured in rotation with the main body 5, for example by means of pins or ribs 16b internal neck 16, which penetrate in external axial grooves 15b of the control part 15.

Par ailleurs, comme représenté notamment sur les figures 2, 3, 3B, 8, 9, le deuxième embout 7 est solidarisé avec le corps principal 5 par clipsage et est solidarisé en rotation avec une bague interne 17, par exemple par butée axiale de cette bague interne contre le deuxième embout et par des nervures axiales internes 7b du deuxième embout pénétrant dans des échancrures 17a de la bague interne, ces échancrures 17a délimitant des pattes élastiques 17b qui viennent en appui latéral contre la bague de fixation 10 susmentionnée, de sorte que cette bague de fixation 10 peut coulisser axialement dans la bague interne 17 selon la direction X.Moreover, as represented in particular on figures 2 , 3 , 3B , 8 , 9 , the second endpiece 7 is secured to the main body 5 by clipping and is secured in rotation with an inner ring 17, for example by axial abutment of the inner ring against the second endpiece and by internal axial ribs 7b of the second endpiece penetrating into indentations 17a of the inner ring, these notches 17a delimiting elastic tabs 17b which bear laterally against the aforementioned fixing ring 10, so that this fixing ring 10 can slide axially in the inner ring 17 in the direction X.

Le dispositif qui vient d'être décrit fonctionne comme suit.The device that has just been described operates as follows.

Lorsqu'un utilisateur fait tourner le premier embout 6 par rapport au corps principal 5 dans le sens de la flèche 18 visible sur la figure 10, cette rotation fait également tourner la pièce d'entraînement 13, qui entraîne une rotation du poussoir 2 du fait que les nervures 13c de la pièce d'entraînement pénètrent dans les rainures 2b du poussoir. De ce fait, les pions 2c du poussoir coulissent dans les rainures hélicoïdales 15a de la pièce de commande, qui est solidarisée en rotation avec le corps principal 5. Il en résulte que le poussoir 2 sort du premier embout 6 dans la direction de la flèche 19 (figure 10) et lorsque le poussoir arrive en position de butée axiale contre le premier embout 6, la rotation du poussoir 2 entraîne un coulissement de la pièce de commande 13 dans le col 16 vers le deuxième embout 7, ce qui entraîne également le réservoir 8 dans la même direction, de sorte que la buse 3 sort du deuxième embout 7 dans la direction de la flèche 20 (figure 10).When a user turns the first endpiece 6 relative to the main body 5 in the direction of the arrow 18 visible on the figure 10 , This rotation also rotates the drive part 13, which causes a rotation of the pusher 2 that the ribs 13c of the drive part penetrate into the grooves 2b of the pusher. As a result, the pins 2c of the pusher slide in the helical grooves 15a of the control part, which is secured in rotation with the main body 5. As a result, the pusher 2 leaves the first end-piece 6 in the direction of the arrow 19 ( figure 10 ) and when the pusher reaches the axial abutment position against the first end-piece 6, the rotation of the pusher 2 causes the control part 13 to slide in the neck 16 towards the second end-piece 7, which also causes the reservoir 8 in the same direction, so that the nozzle 3 leaves the second nozzle 7 in the direction of the arrow 20 ( figure 10 ).

Lorsque l'utilisateur veut ensuite utiliser le distributeur 1 pour distribuer une dose du produit liquide P, il appuie sur le poussoir 2, ce qui déplace également le réservoir 8 et la pompe 9 vers le deuxième embout 7 en faisant coulisser la bague de fixation 10 dans les pattes élastiques 17b de la bague interne, tandis que la buse est bloquée en translation, par exemple par butée d'un épaulement externe 3b de ladite buse contre un rétrécissement 17c de la bague interne 17. Il en résulte que la tige 9b de la pompe pénètre dans le corps 9a de ladite pompe en actionnant la pompe, provoquant la sortie de la dose de produit P.When the user then wants to use the dispenser 1 to dispense a dose of the liquid product P, he presses the pusher 2, which also moves the reservoir 8 and the pump 9 towards the second end 7 by sliding the fixing ring 10 in the elastic tabs 17b of the inner ring, while the nozzle is locked in translation, for example by abutment of an outer shoulder 3b of said nozzle against a narrowing 17c of the inner ring 17. As a result, the rod 9b of the pump enters the body 9a of said pump by actuating the pump, causing the output of the dose of product P.

On obtient ainsi une distribution (pulvérisation notamment) particulièrement précise de la dose de produit P, et ce quasiment sans risque de voir l'utilisateur mettre les doigts sur la buse 3. De plus, le poussoir n'étant pas à proximité immédiate de la buse 3, cela permet en outre de limiter d'éventuelles contaminations bactériennes du produit P via l'orifice 3a de la buse, contaminations que l'on est susceptible d'apporter via ses doigts en actionnant le poussoir. Ces dispositions sont particulièrement avantageuses lorsque le réservoir 8 contient un produit P qui n'est pas un parfum.This provides a distribution (particularly spraying) particularly accurate dose of product P, and almost without risk to see the user put his fingers on the nozzle 3. In addition, the pusher is not in the immediate vicinity of the nozzle 3, this also makes it possible to limit any bacterial contamination of the product P via the orifice 3a of the nozzle, contaminations that it is likely to bring via his fingers by operating the pusher. These provisions are particularly advantageous when the reservoir 8 contains a product P which is not a perfume.
