Description

ENSEMBLE POUR LA DISTRIBUTION D'UN PRODUIT PÂTEUX OU D'UN GEL SET FOR THE DISPENSING OF A PASTY PRODUCT OR A GEL
La présente invention concerne un ensemble pour la distribution d'un produit pâteux ou d'un gel. L'ensemble selon l'invention est du type comportant une pompe sans reprise d'air. Dans ces conditions, le récipient contenant le produit à distribuer doit être à volume variable, c 'est-à-dire que son volume doit être susceptible de diminuer au fur et à mesure de la distribution du produit. De façon connue, le récipient à volume variable peut être un récipient rigide contenant un piston suiveur qui remonte vers la pompe au fur et à mesure de la distribution, ou un récipient à paroi déformable en matière plastique souple, ou pliée en forme d'accordéon. La pompe est généralement fixée par sertissage du corps de pompe sur une coupelle de sertissage ou un plateau ; la pompe comporte une tige émergente creuse, qui permet à la fois d'actionner la pompe et de faire sortir le produit. On actionne la pompe à l'aide d'une tête de distribution en enfonçant la tige émergente, la tête de distribution contenant des canaux de distribution s' ouvrant vers l'extérieur. Ce type d'ensemble de distribution est généralement utilisé pour des produits liquides ou faiblement visqueux et le produit est pulvérisé à partir de la tête de distribution.The present invention relates to an assembly for dispensing a pasty product or a gel. The assembly according to the invention is of the type comprising a pump without air intake. Under these conditions, the container containing the product to be dispensed must be of variable volume, that is to say that its volume must be capable of decreasing as the product is dispensed. In a known manner, the variable-volume container can be a rigid container containing a follower piston which rises towards the pump as it is dispensed, or a container with a deformable wall of flexible plastic material, or folded in the form of an accordion . The pump is generally fixed by crimping the pump body on a crimping cup or a plate; the pump has a hollow emerging rod, which both activates the pump and lets the product out. The pump is actuated using a dispensing head by pushing in the emerging rod, the dispensing head containing dispensing channels opening outwards. This type of dispensing assembly is generally used for liquid or slightly viscous products and the product is sprayed from the dispensing head.
Pour les produits visqueux, tels que les déodorants, on utilise généralement un ensemble où le produit est dans un récipient muni d'un piston suiveur et où on pousse le piston à l'aide d'un mécanisme à mollette pour faire sortir le produit. Ce système présente plusieurs inconvénients : d'une part, le produit n'est pas protégé de l'air ambiant au cours du stockage, car, bien que l'on ferme le récipient par un couvercle, celui-ci n'est pas étanche de sorte que, pour protéger le produit pendant le stockage, il est nécessaire de mettre une pellicule de protection sur la tête de distribution, d'autre part, l'application du produit nécessite deux gestes successifs : actionner la molette et appliquer le produit.For viscous products, such as deodorants, an assembly is generally used where the product is in a container fitted with a follower piston and where the piston is pushed using a rotary mechanism to release the product. This system has several drawbacks: on the one hand, the product is not protected from ambient air during storage, because, although the container is closed by a lid, it is not waterproof so that, to protect the product during storage, it is necessary to put a protective film on the dispensing head, on the other hand, the application of the product requires two successive gestures: actuate the wheel and apply the product.
La présente invention concerne un ensemble distributeur qui permet d'utiliser une pompe pour la distribution d'un produit fluide relativement visqueux, c'est-à-dire sous forme de pâte et de gel, et qui a l'avantage de ne nécessiter qu'un seul geste pour la distribution et l'application du produit.The present invention relates to a dispenser assembly which makes it possible to use a pump for dispensing a relatively viscous fluid product, that is to say in the form of a paste and gel, and which has the advantage of requiring only one gesture for the distribution and application of the product.
Selon l'invention, on utilise un récipient à volume variable muni d'une pompe associée à une tête de distribution qui permet, en un seul geste, d'actionner la pompe et d'effectuer l'application, la pression exercée par l'utilisateur sur la tête de distribution lors de l'application, par exemple lors de son frottement sur la peau, actionnant la pompe et provoquant la distribution.According to the invention, a variable volume container is used provided with a pump associated with a dispensing head which allows, in a single gesture, to actuate the pump and to carry out the application, the pressure exerted by the user on the dispensing head during application, for example when rubbing it on the skin, actuating the pump and causing the dispensing.
La présente invention a pour objet un ensemble pour la distribution d'un produit fluide visqueux, notamment une pâte ou un gel, comportant un récipient à volume variable contenant le produit à distribuer, la distribution ayant lieu grâce à une pompe sans reprise d'air qui comprend un corps de pompe en libre communication avec l'intérieur du récipient et un organe de sortie du produit, ladite distribution étant mise en oeuvre au moyen d'une tête de distribution comportant des canaux de distribution, qui s'ouvrent à l'extérieur et sont alimentés par l'organe de sortie de la pompe, caractérisé par le fait que la tête de distribution comporte, en premier lieu, une platine, qui est munie d'un moyen d'assemblage sur l'organe de sortie de pompe et d'une ouverture au droit dudit organe de sortie de pompe, et, en second lieu, un élément applicateur, qui est, d'une part, solidaire de la platine, d'autre part, disposé du côté de la platine où ne se trouve pas le récipient et, enfin, muni d'ouvertures s'ouvrant vers l'extérieur, les canaux de distribution, qui relient l'organe de sortie de pompe aux ouvertures de l'élément applicateur étant disposés entre la platine et ledit élément applicateur.The subject of the present invention is an assembly for the distribution of a viscous fluid product, in particular a paste or a gel, comprising a variable-volume container containing the product to be distributed, the distribution taking place by means of a pump without air intake. which comprises a pump body in free communication with the interior of the container and a product outlet member, said distribution being implemented by means of a distribution head comprising distribution channels, which open to the outside and are supplied by the pump outlet member, characterized in that the dispensing head comprises, firstly, a plate, which is provided with a means of assembly on the pump outlet member and an opening at right of said pump outlet member, and, secondly, an applicator element, which is, on the one hand, integral with the plate, on the other hand, disposed on the side of the plate where is not the container and, finally, provided with openings opening towards the outside, the distribution channels, which connect the pump outlet member to the openings of the applicator element being arranged between the plate and said applicator element.
Dans ces conditions, lorsqu'on appuie l'élément applicateur sur la peau, on actionne simultanément la pompe, car l'élément applicateur et la platine sont solidaires. Le produit sort par les ouvertures de l'élément applicateur grâce aux canaux reliant l'organe de sortie de pompe et les ouvertures de l'élément applicateur. Selon l'invention, on utilise donc la pression exercée sur la tête de distribution lors de l'application pour actionner la pompe.Under these conditions, when the applicator element is pressed against the skin, the pump is actuated simultaneously, since the applicator element and the plate are integral. The product leaves through the openings of the applicator element through the channels connecting the pump outlet member and the openings of the applicator element. According to the invention, therefore, the pressure exerted on the dispensing head is used during application to actuate the pump.
Avantageusement, la pompe est une pompe à tige émergente, ladite tige étant creuse pour constituer l'organe de sortie du produit et pouvant être enfoncée vers le corps de pompe pour assurer la distribution dudit produit.Advantageously, the pump is a pump with an emerging rod, said rod being hollow to constitute the outlet member of the product and can be pushed towards the pump body to ensure the distribution of said product.
Selon l'invention, les canaux de distribution peuvent être ménagés dans la platine ou dans le support, ou également partiellement dans la surface de la platine tournée vers l'élément applicateur et partiellement dans la surface de l 'élément applicateur tournée vers la platine, les surfaces de la platine et de l'élément applicateur étant complémentaires et formant les canaux lorsqu'on les dispose l'une contre l'autre. De préférence, les différents canaux reliant la sortie de pompe aux différentes ouvertures de l'élément applicateur ont des sections variables, de façon à obtenir pour chaque trou d'ouverture de l'élément applicateur des débits égaux de produit à distribuer en fonction de la longueur des différents canaux, c'est-à-dire en fonction de la disposition relative des différentes ouvertures et de la sortie de pompe.According to the invention, the distribution channels can be provided in the plate or in the support, or also partially in the surface of the plate facing the applicator element and partially in the surface of the applicator element facing the plate, the surfaces of the plate and of the applicator element being complementary and forming the channels when they are placed one against the other. Preferably, the different channels connecting the pump outlet to the different openings of the applicator element have variable sections, so as to obtain for each opening hole of the applicator element equal flow rates of product to be distributed according to the length of the different channels, that is to say as a function of the relative arrangement of the different openings and of the pump outlet.
Selon l'invention, la platine est avantageusement une plaque généralement plane ou légèrement bombée. Elle est avantageusemnt munie d'une ouverture entourée d'un manchon tourné vers le récipient et destiné à la fixation de la tige de pompe.According to the invention, the plate is advantageously a generally flat or slightly curved plate. It is advantageously provided with an opening surrounded by a sleeve facing the container and intended for fixing the pump rod.
Selon un premier mode de réalisation de l'invention, l'élément applicateur comporte une plaque plane ou légèrement bombée munie d'ouvertures régulièrement réparties. Lors de l'utilisation, l'utilisateur frotte sur la peau l' applicateur et, simultanément, il actionne la pompe et répartit le produit à distribuer sortant par les ouvertures ménagées dans la plaque.According to a first embodiment of the invention, the applicator element comprises a flat or slightly convex plate provided with regularly distributed openings. During use, the user rubs the applicator on the skin and, simultaneously, he activates the pump and distributes the product to be dispensed leaving through the openings in the plate.
Selon un deuxième mode de réalisation, l'élément applicateur comporte une coupelle dont le fond est muni d'ouvertures et sur les parois latérales de laquelle est fixé au moins un rouleau ; l'axe du rouleau est perpendiculaire à l'axe du récipient ; le rouleau est muni de lames radiales, l'axe du rouleau étant disposé de façon que le bord des lames radiales frotte sur le fond de la coupelle et puisse prélever le produit distribué par les ouvertures disposées dans le fond de la coupelle. Le bord des lames est, de préférence, découpé de façon régulière, par exemple en forme de sinusoïde. Selon un troisième mode de réalisation de l'invention, l'élément applicateur comporte un support muni d'alvéoles en forme de calotte sphérique dans lesquelles sont disposées des billes, des ouvertures étant ménagées dans le support, au fond des alvéoles. Selon un quatrième mode de réalisation de l'invention, l'élément applicateur comporte un peigne constitué d'une plaque de base à partir de laquelle font saillie vers l'extérieur des dents ayant la forme de prismes de section droite triangulaire ou trapézoïdale. De préférence, les dents sont formées de prismes à section trapézoïdale isocèle dont les arêtes sont disposées parallèlement. Les ouvertures peuvent être disposées dans la plaque de base entre les dents mais s'ouvrent, de préférence, dans les parois latérales des prismes formant les dents.According to a second embodiment, the applicator element comprises a cup whose bottom is provided with openings and on the side walls of which is fixed at least one roller; the axis of the roller is perpendicular to the axis of the container; the roller is provided with radial blades, the axis of the roller being arranged so that the edge of the radial blades rubs against the bottom of the cup and can take the product dispensed through the openings arranged in the bottom of the cup. The edge of the blades is preferably cut out regularly, for example in the form of a sinusoid. According to a third embodiment of the invention, the applicator element comprises a support provided with cells in the form of a spherical cap in which balls are arranged, openings being formed in the support, at the bottom of the cells. According to a fourth embodiment of the invention, the applicator element comprises a comb consisting of a base plate from which project outwardly teeth having the shape of prisms of triangular or trapezoidal cross section. Preferably, the teeth are formed of prisms with an isosceles trapezoidal section, the edges of which are arranged in parallel. The openings can be arranged in the base plate between the teeth but preferably open in the side walls of the prisms forming the teeth.
Comme indiqué ci-dessus, l'ensemble platine-élément applicateur constitue le système d'actionnement de la pompe. Dans ce but, cet ensemble est fixé sur la tige de pompe et il est susceptible de translation linéaire lorsque l'utilisateur appuie sur l'élément applicateur ; l'élément applicateur comporte généralement une jupe susceptible de coulisser sur la paroi latérale du récipient. La pompe utilisée selon l' invention peut être toute pompe sans reprise d'air. On utilise, de préférence, une pompe "douce" , qui est actionnée pour une pression inférieure à 1 kg/m2.As indicated above, the plate-applicator element assembly constitutes the pump actuation system. For this purpose, this assembly is fixed on the pump rod and it is capable of linear translation when the user presses on the applicator element; the applicator element generally comprises a skirt capable of sliding on the side wall of the container. The pump used according to the invention can be any pump without air intake. Preferably, a "soft" pump is used, which is actuated for a pressure of less than 1 kg / m 2 .
La pompe utilisée dans l'ensemble distributeur selon l'invention ne comportant pas de reprise d'air, le récipient contenant le produit à distribuer est à volume variable, comme expliqué ci-dessus. Il peut être constitué par un sac à parois déformables, qui se déforme au fur et à mesure que le produit est distribué ou par un récipient plié en accordéon dont les plis se referment. Il est, de préférence, constitué par une enveloppe rigide dans laquelle coulisse de façon étanche un piston suiveur qui se rapproche de la pompe au fur et à mesure de la distribution du produit. Le fond de l'enveloppe rigide peut être ouvert ou il peut être fermé, une ouverture étant alors ménagée pour permettre une rentrée d'air.Since the pump used in the dispenser assembly according to the invention does not include an air intake, the container containing the product to be dispensed is of variable volume, as explained above. It can consist of a bag with deformable walls, which deforms as the product is distributed or by a container folded in an accordion whose folds close. It is preferably constituted by a rigid envelope in which slides in leaktight manner a follower piston which approaches the pump as the product is dispensed. The bottom of the rigid envelope can be opened or it can be closed, an opening being then made to allow an air intake.
La tête de distribution de l'ensemble selon la présente invention est, de préférence, recouverte d'un capot. Pour mieux faire comprendre l'objet de l' invention, on va en décrire maintenant, à titre d'exemples purement illustratifs et non limitatifs, plusieurs modes de réalisation représentés sur le dessin annexé.

L'ensemble de distribution représenté sur les figures 1 et 2 est désigné dans son ensemble par la référence 1. Il est composé d'un récipient 2, qui est équipé d'une pompe 3 et d'une tête de distribution 4, la tête de distribution étant coiffée d'un capot de protection 38. Le récipient 2 est un récipient en matériau rigide, en particulier en matière plastique rigide, dans lequel coulisse de façon étanche un piston suiveur 5. Le récipient 2 est constitué par une paroi latérale 6 définissant un cylindre de section ovale, comme visible sur la figure 2. La paroi latérale 6 comporte, à ses extrémités inférieure et supérieure, une feuillure dont le fond est formé par une partie de paroi latérale d'épaisseur réduite (respectivement 7 et 8). La feuillure correspondant à la partie 7 permet d'emboîter sur la paroi latérale 6 une embase 9 en forme de coupelle dont le fond est pourvu d'une ouverture 10 pour la rentrée d'air. Il est bien évident que l'embase 9 pourrait être supprimée, car elle a essentiellement une fonction esthétique. Le récipient 2 est fermé à son extrémité opposée à l'embase 9 par un plateau 11, qui est moulé d'une pièce avec la paroi latérale 6 du récipient 2. Le plateau l i a une forme de cuvette, dont la concavité est tournée vers l'extérieur du récipient 2, et porte un manchon axial 12 ouvert à ses deux extrémités et faisant saillie vers l'extérieur du récipient 2.The distribution assembly represented in FIGS. 1 and 2 is generally designated by the reference 1. It is composed of a container 2, which is equipped with a pump 3 and a distribution head 4, the head dispenser being capped with a protective cover 38. The container 2 is a container made of rigid material, in particular rigid plastic, in which slides a follower piston 5. The container 2 is constituted by a side wall 6 defining a cylinder of oval section, as visible in FIG. 2. The side wall 6 comprises, at its lower and upper ends, a rebate whose bottom is formed by a part of side wall of reduced thickness (respectively 7 and 8). The rebate corresponding to the part 7 allows to fit on the side wall 6 a base 9 in the form of a cup, the bottom of which is provided with an opening 10 for the return of air. It is obvious that the base 9 could be omitted, since it essentially has an aesthetic function. The container 2 is closed at its end opposite to the base 9 by a plate 11, which is molded in one piece with the side wall 6 of the container 2. The plate 11a has the shape of a bowl, the concavity of which faces towards outside the container 2, and carries an axial sleeve 12 open at its two ends and projecting towards the outside of the container 2.
La pompe 3 est une pompe de type classique comportant un corps de pompe 13 muni, à sa partie inférieure (sur la figure 1), d'une ouverture 14 mettant en communication le corps de pompe 13 avec le produit P contenu à l'intérieur du récipient 2 et, à sa partie supérieure (sur la figure 1), d'une tige creuse 15 mobile qui, de façon connue, sert, à la fois au déplacement du piston de la pompe dans le corps de pompe et à la sortie du produit à distribuer. Le corps de pompe 13 est disposé à l'intérieur du manchon 12 et il est serti sur celui-ci à l'aide d'une bague métallique 16, un joint d'étanchéité 17 étant disposé entre le bord supérieur du manchon 12 et la bague métallique de sertissage 16.The pump 3 is a conventional type pump comprising a pump body 13 provided, at its lower part (in FIG. 1), with an opening 14 putting the pump body 13 in communication with the product P contained inside. of the container 2 and, at its upper part (in FIG. 1), of a movable hollow rod 15 which, in known manner, is used both for the displacement of the pump piston in the pump body and for the outlet of the product to be distributed. The pump body 13 is disposed inside the sleeve 12 and it is crimped onto the latter using a metal ring 16, a seal 17 being disposed between the upper edge of the sleeve 12 and the metal crimp ring 16.
La tête de distribution 4 est constituée d'une platine 18 et d'un élément distributeur 19, la platine 18 étant emboîtée à force dans l'élément distributeur 19. Dans le mode de réalisation représenté sur la figure 1, la platine 18 a la forme d'une plaque bombée, sa convexité étant tournée vers l'extérieur ; une ouverture 25 est ménagée dans la platine 18. Un manchon 20 tourné vers l' intérieur de l'ensemble entoure l'ouverture 25 et fait saillie sous la platine ; ce manchon 20 a un diamètre intérieur égal, au jeu nécessaire près, au diamètre extérieur de la tige de pompe 15. L'élément applicateur 19 est constitué d'une paroi latérale 21 et d'un fond 22 ovale, qui a, en section, une forme ovale, comme le récipient 2, et qui a des dimensions internes telles que la surface interne de cette paroi latérale 21 soit susceptible de coulisser dans la feuillure correspondant à la partie de faible épaisseur 8 de la paroi latérale 6 du récipient 2. La platine 18 est en appui contre le fond 22 et a les mêmes contours que ce fond.The dispensing head 4 consists of a plate 18 and a distributor element 19, the plate 18 being forced into the distributor element 19. In the embodiment shown in FIG. 1, the plate 18 has the shape of a curved plate, its convexity being turned towards the outside; an opening 25 is formed in the plate 18. A sleeve 20 turned towards the inside of the assembly surrounds the opening 25 and projects under the plate; this sleeve 20 has an inside diameter equal, apart from the necessary clearance, to the outside diameter of the pump rod 15. The applicator element 19 consists of a side wall 21 and an oval bottom 22, which has, in section, an oval shape, like the container 2, and which has internal dimensions such as the internal surface of this wall side 21 is capable of sliding in the rebate corresponding to the thin part 8 of the side wall 6 of the container 2. The plate 18 is in abutment against the bottom 22 and has the same contours as this bottom.
La paroi latérale 21 a une hauteur telle que lorsque la tête de distribution 4 est fixée par le manchon 20 sur la tige de pompe 15, il reste un certain jeu entre le bord inférieur de la paroi latérale 21 et l'épaulement qui limite la feuillure correspondant à la partie de faible épaisseur 8, de façon à permettre à la paroi latérale 21 de coulisser dans ladite feuillure quand on enfonce la tige 15 dans le corps de pompe 13. Des ouvertures 23 sont ménagées dans le fond 22. Dans le mode de réalisation représenté sur la figure 2, il y a huit ouvertures disposées symétriquement par rapport au grand axe du fond 22, les ouvertures 23 situées d'un même côté du grand axe étant situées à une distance d les unes des autres ; les deux rangées symétriques d'ouvertures 23 sont également situées à cette même distance d l'une de l'autre.The side wall 21 has a height such that when the dispensing head 4 is fixed by the sleeve 20 on the pump rod 15, there is a certain clearance between the lower edge of the side wall 21 and the shoulder which limits the rebate corresponding to the thin part 8, so as to allow the side wall 21 to slide in said rebate when the rod 15 is pressed into the pump body 13. Openings 23 are formed in the bottom 22. In the mode of embodiment shown in Figure 2, there are eight openings arranged symmetrically relative to the major axis of the bottom 22, the openings 23 located on the same side of the major axis being located at a distance from each other; the two symmetrical rows of openings 23 are also located at the same distance from one another.
D'autres dispositions des ouvertures 23 sont également possibles, en particulier en fonction de la forme de l'ensemble 1. Les ouvertures peuvent, par exemple, être disposées sur un cercle, sur une ellipse ou être alignées.Other arrangements of the openings 23 are also possible, in particular depending on the shape of the assembly 1. The openings can, for example, be arranged on a circle, on an ellipse or be aligned.
Dans ce mode de réalisation, l'ensemble des canaux de distribution 24 est constitué par des rainures ménagées dans la platineIn this embodiment, all of the distribution channels 24 are formed by grooves made in the plate
18, rainures qui sont fermées par l 'élément applicateur 19 lorsque la platine 18 est mise en appui, par engagement à force, contre ledit élément applicateur 19. Les différents canaux relient l'ouverture 25 de la platine 18 correspondant au manchon 20 et les ouvertures 23 de l'élément applicateur 19. Le dessin formé par l'ensemble des canaux 24 est celui représenté sur la figure 2, c'est-à-dire qu' il comporte, le long du grand axe, un canal axial 26 passant par l'ouverture 25, relié à chaque extrémité à des canaux 27 disposés en X, le canal 26 débouchant au centre du X ; un canal 28, passant par l'ouverture 25, est disposé selon le petit axe de la platine 18, et est relié, par leurs milieux, à deux canaux 29 symétriques, parallèles au canal 26 ; les canaux 29 relient deux à deux les quatre ouvertures 24 les plus proches de l'ouverture 25. Le canal 26 a, en section, des dimensions supérieures à celles des autres canaux 27, 28 et 29. Cette disposition a l'avantage de permettre une distribution uniforme du produit à distribuer.18, grooves which are closed by the applicator element 19 when the plate 18 is pressed, by force engagement, against said applicator element 19. The different channels connect the opening 25 of the plate 18 corresponding to the sleeve 20 and the openings 23 of the applicator element 19. The drawing formed by the set of channels 24 is that shown in FIG. 2, that is to say that it comprises, along the long axis, an axial channel 26 passing by the opening 25, connected at each end to channels 27 arranged in X, the channel 26 opening at the center of the X; a channel 28, passing through the opening 25, is arranged along the minor axis of the plate 18, and is connected, by their midpoints, to two symmetrical channels 29, parallel to the channel 26; the channels 29 connect two by two the four openings 24 closest to the opening 25. The channel 26 has, in section, dimensions greater than those of the other channels 27, 28 and 29. This arrangement has the advantage of allowing uniform distribution of the product to be distributed.
Sur les figures 3 à 10, sont représentés trois autres modes de réalisation de la tête de distribution ; le récipient, auquel sont associées ces têtes de distribution, est identique à celui représenté sur la figure 1 et n'a, par conséquent, pas été représenté.Figures 3 to 10 show three other embodiments of the dispensing head; the container, with which these dispensing heads are associated, is identical to that shown in FIG. 1 and has therefore not been shown.
Dans le mode de réalisation représenté sur les figures 3 à 5, la tête de distribution est désignée dans son ensemble par la référence 104. La tête de distribution 104 comporte une platine 118 et un élément applicateur 119. Dans la platine 1 18 est ménagée une ouverture 125 entourée par un manchon 120 faisant saillie vers le récipient.

Le fond de la cuvette 122a a la forme d'un secteur de cylindre droit ; il s'emboîte sur la platine 1 18 à l 'aide d'un bourrelet 122b ; il est muni d'ouvertures 123 qui sont disposées comme décrit ci-dessus pour les figures 1 et 2 ; les canaux 124 ont également la même configuration que celle décrite pour les figures 1 et 2. Sur la surface interne de la paroi latérale 122ç de la cuvette, sont ménagées deux encoches 122d ; un rouleau 130 est fixé par son axe 131 dans les deux encoches 122d. Le rouleau 130 comporte des lamelles radiales 132 rayonnant à partir d'un noyau cylindrique central 133 ; le bord des lamelles 132 est découpé en forme de sinusoïde, comme visible sur la figure 3.In the embodiment shown in Figures 3 to 5, the dispensing head is designated as a whole by the reference 104. The dispensing head 104 comprises a plate 118 and an applicator element 119. In the plate 1 18 is formed a opening 125 surrounded by a sleeve 120 projecting towards the container. The pump rod 115 is fitted into the sleeve 120. The applicator element 119 comprises a skirt 121 capable of sliding on the outer wall of the container, as explained above during the description of FIG. 1. The skirt 121 is connected to a bottom 122 in the form of a bowl, the concavity of the bowl being turned upwards. The bottom of the bowl 122a has the shape of a straight cylinder sector; it fits onto the plate 1 18 using a bead 122b; it is provided with openings 123 which are arranged as described above for Figures 1 and 2; the channels 124 also have the same configuration as that described for FIGS. 1 and 2. On the internal surface of the side wall 122 c of the bowl, two notches 122 d are formed; a roller 130 is fixed by its axis 131 in the two notches 122d. The roller 130 comprises radial strips 132 radiating from a central cylindrical core 133; the edge of the slats 132 is cut in the form of a sinusoid, as visible in FIG. 3.
Le dispositif fonctionne de la façon suivante. Lorsque l'utilisateur veut appliquer le produit sur la peau, il appuie sur la peau la tête de distribution 104 et enfonce donc la tige de pompe 115 ; le produit passe par l'ouverture 125, par les canaux 124 et par les ouvertures 123. Comme l'utilisateur fait rouler le rouleau 130 sur la peau, le rouleau tourne, les lamelles 132 prélèvent alors le produit qui sort par les ouvertures 123 et le déposent sur la peau.The device operates as follows. When the user wants to apply the product to the skin, he presses on the skin the dispensing head 104 and therefore pushes the pump rod 115; the product passes through the opening 125, through the channels 124 and through the openings 123. As the user rolls the roller 130 on the skin, the roller rotates, the strips 132 then take the product which leaves through the openings 123 and deposit it on the skin.
