Description

La présente invention est relative à un ensemble de protection et de bouchage d'un distributeur de produit pâteux, par exemple un distributeur doseur de pâte dentifrice à piston et à pompe de distribution sans reprise d'air, ayant un orifice de distribution excentré.The present invention relates to a protection and closure assembly of a pasty product distributor, for example a metering distributor of toothpaste with piston and distribution pump without air intake, having an eccentric distribution orifice.

De nombreux distributeurs doseurs de dentifrice sont constitués, d'une part, par une partie récipient rigide, généralement cylindrique, et d'autre part, par un capuchon de distribution, qui coiffe ladite partie récipient et est relié aux moyens du distributeur permettant l'éjection du produit. Ce capuchon de distribution comporte, le plus souvent, un canal de distribution dont l'extrémité libre, excentrée, définit l'orifice de distribution.Many toothpaste dispensers consist, on the one hand, of a rigid container part, generally cylindrical, and on the other hand, by a dispensing cap, which covers said container part and is connected to the means of the distributor allowing the product ejection. This dispensing cap most often comprises a dispensing channel whose free, eccentric end defines the dispensing orifice.

On connaît déjà pour de tels distributeurs doseurs des capots de protection, qui, lorsqu'on ne se sert pas des distributeurs, recouvrent les capuchons de distribution. Ces capots de protection ont pour fonction essentielle de protéger le capuchon de distribution contre les chocs extérieurs qui pourraient le détériorer. Ils n'ont aucune fonction de bouchage de l'orifice de distribution. La matière dans le canal, directement à l'air libre ou en contact avec l'air compris sous le capot de protection, a tendance à sécher dans le canal d'éjection, à le salir et à l'obstruer.Protective covers are already known for such dispensing dispensers, which, when dispensers are not used, cover the dispensing caps. These protective covers have the essential function of protecting the dispensing cap against external shocks which could damage it. They have no function of blocking the dispensing orifice. The material in the channel, directly in the open air or in contact with the air included under the protective cover, tends to dry in the ejection channel, to dirty it and to obstruct it.

Certains distributeurs doseurs de dentifrice sont présentés à la vente, c'est-à-dire avant la première utilisation par le consommateur, munis d'une petite capsule venant boucher l'orifice de distribution. Cette petite capsule, qui est une pièce disjointe du reste du dispositif, sert essentiellement à éviter que la matière comprise dans le distributeur verseur ne sèche pendant le stockage avant vente et se jette, généralement, dès la première utilisation.Some toothpaste dispensers are presented for sale, that is to say before the first use by the consumer, provided with a small capsule blocking the dispensing orifice. This small capsule, which is a separate piece from the rest of the device, essentially serves to prevent the material included in the pouring dispenser from drying during storage before sale and is generally thrown away from the first use.

Il existe déjà, pour les récipients ayant une forme de révolution et un orifice centre sur leur axe, des capots destinés à accompagner lesdits récipients tout au long de leur utilisation et ayant à la fois une fonction de protection et une fonction de bouchage. Le fond du capot est muni, par exemple, d'une protubérance intérieure qui s'insère, en position de bouchage, dans l'orifice de distribution et l'obture. Pour associer un capot de protection et un récipient en position de bouchage, il suffit, généralement, d'enfiler le capot sur le goulot du récipient dans n'importe quelle position angulaire, puis, par exemple, de faire coopérer les pas de vis respectifs s'ils existent.There are already, for containers having a shape of revolution and an orifice centered on their axis, covers intended to accompany said containers throughout their use and having both a protective function and a function of capping. The bottom of the cover is provided, for example, with an internal protuberance which is inserted, in the plugged position, in the dispensing orifice and plugs it. To associate a protective cover and a container in the plugging position, it is generally sufficient to thread the cover on the neck of the container in any angular position, then, for example, to make the respective screw threads cooperate. if they exist.

Cependant, l'utilisation de capots de protection similaires pour des récipients à orifice excentré est beaucoup moins commode, puisqu'il faut nécessairement que les organes de bouchage se présentent exactement dans la position angulaire leur permettant de s'assembler avec l'orifice de sortie. Pour faciliter cette mise en place, on utilise souvent des moyens de détrompage qui ne permettent d'engager une pièce sur l'autre que dans une position angulaire prédéterminée. Une telle solution présente l'inconvénient d'obliger l'utilisateur à tâtonner pour trouver la position angulaire convenable qui permet un engagement dans les moyens de détrompage.However, the use of similar protective covers for containers with an eccentric opening is much less convenient, since it is necessarily necessary for the closure members to be present exactly in the angular position allowing them to be assembled with the outlet opening. . To facilitate this positioning, polarization means are often used which only allow one part to be engaged on the other in a predetermined angular position. Such a solution has the drawback of forcing the user to grope around to find the suitable angular position which allows engagement in the polarizing means.

La présente invention propose une solution qui permet d'éviter ou tout au moins de réduire un tel tâtonnement. Le capot de protection et le capuchon de distribution sont munis de moyens appropriés pour guider l'assemblage et conduire l'orifice de sortie excentré sur un organe de bouchage.The present invention provides a solution which makes it possible to avoid or at least reduce such trial and error. The protective cover and the distribution cap are provided with suitable means for guiding the assembly and conducting the eccentric outlet orifice on a closure member.

Des moyens appropriés pour guider un capot diffuseur sur la tête de valve d'un récipient aérosol ont été proposés dans le document FR-A- 2 327 158 ; ces moyens permettent le montage en automatique, sur la chaîne de production, du capot diffuseur sur la tête de valve de façon que la fenêtre de diffusion se trouve face à l'ajutage de la valve ; ces moyens sont constitués d'au moins une saillie de conduite et d'au moins une rampe de guidage avec laquelle ladite saillie coopère, lesdits moyens étant portés par le capot et la tête de valve ; aucun moyen de bouchage de l'ajutage de la valve n'est prévu.Appropriate means for guiding a diffuser cover over the valve head of an aerosol container have been proposed in document FR-A-2 327 158; these means allow the automatic mounting, on the production line, of the diffuser cover on the valve head so that the diffusion window is facing the nozzle of the valve; these means consist of at least one pipe projection and at least one guide ramp with which said projection cooperates, said means being carried by the cover and the valve head; no means of plugging the valve nozzle is provided.

La présente invention a donc pour objet un ensemble de protection et de bouchage d'un distributeur de produit pâteux, par exemple de pâte dentifrice, qui comporte un capot de protection et un capuchon de distribution montés sur une partie récipient du distributeur, ledit capuchon de distribution ayant une forme générale de révolution et comprenant une ouverture de distribution latérale excentrée, le capuchon de distribution et le capot de protection étant munis, respectivement sur leur surface externe et sur leur surface interne, d'au moins une saillie de conduite et d'au moins une rampe de guidage destinées à coopérer lorsqu'on applique ledit capot de protection sur ledit capuchon de distribution pour guider le capot de protection sur le capuchon de distribution, caractérisé par le fait que ledit capot de protection comprend au moins un organe obturateur destiné à s'assembler avec ladite ouverture pour la boucher de façon sensiblement hermétique, l'ouverture de distribution étant formée par l'ouverture d'une cheminée de distribution, latérale, dont l'extrémité opposée à ladite ouverture de distribution est reliée au capuchon de distribution, les bords de ladite cheminée formant les saillies de conduite, destinées à coopérer avec la rampe de guidage portée par le capot de protection pour guider l'organe obturateur et permettre l'assemblage dudit organe obturateur, en position de bouchage, avec l'ouverture, quelle que soit la position relative selon laquelle a été appliqué le capot de protection sur le capuchon.The present invention therefore relates to an assembly for protecting and sealing a dispenser of pasty product, by example of toothpaste, which comprises a protective cover and a dispensing cap mounted on a container part of the dispenser, said dispensing cap having a general shape of revolution and comprising an eccentric lateral dispensing opening, the dispensing cap and the cover of protection being provided, respectively on their outer surface and on their inner surface, with at least one pipe projection and at least one guide ramp intended to cooperate when applying said protective cover to said distribution cap for guide the protective cover over the dispensing cap, characterized in that said protective cover comprises at least one obturating member intended to be assembled with said opening in order to plug it in a substantially hermetic manner, the dispensing opening being formed by the opening of a lateral distribution chimney, the end opposite to said o distribution opening is connected to the distribution cap, the edges of said chimney forming the driving projections, intended to cooperate with the guide ramp carried by the protective cover to guide the shutter member and allow the assembly of said shutter member, in the plugging position, with the opening, regardless of the relative position in which the protective cover has been applied to the cap.

De préférence, la rampe de guidage, ou l'ensemble des rampes de guidage, s'étend sensiblement sur un tour du capot de protection.Preferably, the guide ramp, or all of the guide ramps, extends substantially over one revolution of the protective cover.

De préférence, le (ou les) organe(s) obturateur(s) est (ou sont) disposé(s) sur le fond du capot de protection ; la (ou les) rampe(s) de guidage sur la surface intérieure de la paroi du capot de protection est (ou sont) positionnée(s) de façon que leur extrémité proche du fond du capot de protection soit juxtaposée à un organe obturateur.Preferably, the shutter member (s) is (or are) disposed on the bottom of the protective cover; the guide ramp (s) on the inner surface of the wall of the protective cover is (or are) positioned (s) so that their end close to the bottom of the protective cover is juxtaposed with a shutter member.

Pour mieux faire comprendre l'objet de l'invention, on va décrire maintenant, à titre purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the invention, we will now describe, purely by way of non-limiting illustration, an embodiment shown in the accompanying drawing.

Sur ce dessin :

  • la figure 1 est une vue en perspective éclatée d'un capot de protection et d'un capuchon de distribution montés sur un récipient ;
  • la figure 2 est une vue en coupe longitudinale du capot de protection ;
  • la figure 3, enfin, est une vue en coupe, selon la ligne III-III de la figure 2 du même capot de protection.
On this drawing :
  • Figure 1 is an exploded perspective view of a protective cover and a dispensing cap mounted on a container;
  • Figure 2 is a longitudinal sectional view of the protective cover;
  • Figure 3, finally, is a sectional view along line III-III of Figure 2 of the same protective cover.

En se référant aux dessins, on voit que l'ensemble de protection et de bouchage est constitué par un capot de protection 1 et par un capuchon de distribution 2 monté sur la partie récipient 3 du distributeur.Referring to the drawings, it can be seen that the protection and plugging assembly is constituted by a protective cover 1 and by a dispensing cap 2 mounted on the container part 3 of the dispenser.

Le capot de protection 1 comporte une paroi 4 fermée sur elle-même et terminée à une de ses extrémités par un fond plat 5, son autre extrémité étant libre. Vers son extrémité libre la paroi 4 est un manchon cylindrique 6. Le fond 5 a une forme qui est définie par un cercle 7, de même axe que le manchon 6 et de diamètre légèrement plus petit, à la périphérie duquel sont répartis trois logements en oreille 8, à 120̸° les uns des autres, prolongeant identiquement le fond 5. Ces logements en oreille 8 sont délimités à leur extrémité opposée au cercle 7 délimitant le fond 5 par les arcs d'un cercle de même centre et de même diamètre que le manchon 6.The protective cover 1 has a wall 4 closed on itself and terminated at one of its ends by a flat bottom 5, its other end being free. Towards its free end, the wall 4 is a cylindrical sleeve 6. The bottom 5 has a shape which is defined by a circle 7, of the same axis as the sleeve 6 and of slightly smaller diameter, at the periphery of which are distributed three housings in ear 8, at 120 ° to one another, identically extending the bottom 5. These ear housings 8 are delimited at their end opposite the circle 7 delimiting the bottom 5 by the arcs of a circle with the same center and the same diameter as the sleeve 6.

Les oreilles 8 sont reliées deux à deux par les parois des rampes de guidage 10̸ qui prolongent les extrémités latérales 9, en regard les unes des autres, desdites oreilles 8. Les rampes de guidage 10̸ sont les branches de bandes, d'épaisseur constante, ayant sensiblement la forme d'une dent ou d'un V, dont la pointe, légèrement arrondie est située vers l'extrémité libre du capot de protection 1 et dont les extrémités sont les extrémités latérales 9 des oreilles 8. La paroi 4 du capot de protection 1 relie cylindriquement le contour intérieur de ces rampes de guidage 10̸ au cercle 7, définissant ainsi trois ailettes 11. De plus, la paroi 4, prolongeant cylindriquement le manchon 6, relie les extrémités externes des rampes de guidage 10̸ avec la périphérie du fond 5 délimitée par les arcs de cercle définissant les oreilles 8. De cette façon, deux ailettes 11 déterminent par leurs rampes de guidage 10̸ juxtaposées une gorge 12 fermée sur un côté par la paroi 4 et aboutissant sur le fond 5 aux oreilles 8. Dans une variante, non représentée, les surfaces des ailettes 11, dirigées vers l'intérieur du capot 1, sont légèrement bombées.The ears 8 are connected two by two by the walls of the guide ramps 10̸ which extend the lateral ends 9, facing each other, of said ears 8. The guide ramps 10̸ are the branches of bands, of constant thickness, having substantially the shape of a tooth or a V, the slightly rounded tip of which is situated towards the free end of the protective cover 1 and the ends of which are the lateral ends 9 of the ears 8. The wall 4 of the cover of protection 1 connects the cylindrical inner contour of these guide ramps 10̸ to the circle 7, thus defining three fins 11. In addition, the wall 4, extending the sleeve cylindrically 6, connects the external ends of the guide ramps 10̸ with the periphery of the bottom 5 delimited by the arcs of a circle defining the ears 8. In this way, two fins 11 determine by their guide ramps 10̸ juxtaposed a groove 12 closed on one side by the wall 4 and terminating on the bottom 5 at the ears 8. In a variant, not shown, the surfaces of the fins 11, directed towards the inside of the cover 1, are slightly curved.

Le fond 5 est muni latéralement, sur sa surface intérieure, dans les logements en oreille 8, de trois picots 13. Ces trois picots 13 sont de petits parallépipèdes ayant deux de leurs surfaces légèrement arquées et parallèles aux parties cylindriques de la paroi 4, deux autres de leurs surfaces étant sensiblement parallèles aux parties des rampes de guidages vers les extrémités latérales 9 des oreilles 8, leurs autres surfaces étant parallèles au fond 5. Dans une variante non représentée, le fond 5 est plus épais sur sa surface délimitée par le cercle 7 que sur les logements en oreille 8, la hauteur des picots 13 selon l'axe du capot 1 étant sensiblement égale à l'épaisseur du fond 5 sur sa surface délimitée par le cercle 7 ; chaque picot 13 est alors entouré par une petite gorge annulaire.The bottom 5 is provided laterally, on its inner surface, in the ear receptacles 8, of three pins 13. These three pins 13 are small parallelepipeds having two of their slightly arched surfaces and parallel to the cylindrical parts of the wall 4, two other of their surfaces being substantially parallel to the parts guide rails towards the lateral ends 9 of the ears 8, their other surfaces being parallel to the bottom 5. In a variant not shown, the bottom 5 is thicker on its surface delimited by the circle 7 than on the ear housings 8, the height of the pins 13 along the axis of the cover 1 being substantially equal to the thickness of the bottom 5 on its surface delimited by the circle 7; each pin 13 is then surrounded by a small annular groove.

Le capuchon de distribution 2 comporte un bâti cylindrique 14 dont la section droite est un cercle de diamètre légèrement inférieur à celui du cercle 7. L'intérieur de ce bâti 14 est destiné à contenir les moyens permettant d'actionner le distributeur. A une des extrémités de ce bâti 14, débouche un bouton poussoir 15 relié aux moyens permettant d'actionner le distributeur. Ce bouton poussoir 15 est un cylindre qui coulisse coaxialement dans le bâti 14, son extrémité éloignée dudit bâti étant limitée par une surface plane, légèrement inclinée par rapport à une surface perpendiculaire à l'axe du bâti 14, destinée à recevoir, par exemple, un pouce de main.The dispensing cap 2 comprises a cylindrical frame 14 whose cross section is a circle of diameter slightly smaller than that of the circle 7. The interior of this frame 14 is intended to contain the means making it possible to actuate the dispenser. At one end of this frame 14, opens a push button 15 connected to the means for actuating the dispenser. This push button 15 is a cylinder which slides coaxially in the frame 14, its end remote from said frame being limited by a flat surface, slightly inclined relative to a surface perpendicular to the axis of the frame 14, intended to receive, for example, an inch of a hand.

L'autre extrémité du bâti 14 est reliée par une petite surface annulaire 16 à un col 17 qui est un cylindre creux coaxial au bâti 14, dont la surface intérieure est emboîtée sur le cylindre du récipient 3. Ce col 17 a des dimensions légèrement inférieures à celles du manchon 6. Il est terminé dans sa partie la plus proche du récipient 3 par un rebord 18 qui est une collerette annulaire dont l'épaisseur est celle de la paroi 4. Le capuchon de distribution 2 est muni, le long du bâti 14, d'une cheminée de distribution 19 en regard du point du bouton poussoir 15 le plus haut lorsque le récipient 3 et le capuchon 2 sont verticaux. Cette cheminée 19 est un conduit parallèle audit bâti 14. Ses parois ont sensiblement la forme d'un parallépipède allongé, une des parois en longueur étant légèrement arquée et prolongeant le col 17, la paroi y faisant face épousant partiellement la paroi du bâti 14. Cette cheminée 19 débouche perpendiculairement à une de ses extrémités sur la surface annulaire 16. Son autre extrémité est libre et délimite l'ouverture de distribution 20̸ ayant une forme lui permettant de recevoir exactement les picots 13, l'épaisseur des parois de cette cheminée 19 étant plus petite que la distance minimale séparant la paroi 4 des picots 13, de façon que ladite cheminée 19 puisse être placée dans les gorges 12.The other end of the frame 14 is connected by a small annular surface 16 to a neck 17 which is a hollow cylinder coaxial with the frame 14, the inner surface of which is fitted onto the cylinder of the container 3. This neck 17 has slightly smaller dimensions to those of the sleeve 6. It is terminated in its part closest to the container 3 by a flange 18 which is an annular collar whose thickness is that of the wall 4. The distribution cap 2 is provided, along the frame 14, with a distribution chimney 19 opposite the highest point of the push button 15 when the container 3 and the cap 2 are vertical. This chimney 19 is a duct parallel to said frame 14. Its walls have substantially the shape of an elongated parallelepiped, one of the walls in length being slightly arched and extending the neck 17, the wall facing it partially matching the wall of the frame 14. This chimney 19 opens perpendicularly at one of its ends to the annular surface 16. Its other end is free and delimits the distribution opening 20̸ having a shape allowing it to receive exactly the pins 13, the thickness of the walls of this chimney 19 being smaller than the minimum distance separating the wall 4 from the pins 13, so that said chimney 19 can be placed in the grooves 12.

Lorsque l'on veut refermer le capot de protection 1 sur le capuchon de distribution 2, on engage dans un premier temps le manchon 6 sur la partie du capuchon de distribution 2 opposée au récipient 3, et ce, sans tenir compte de sa position angulaire par rapport audit capuchon.When we want to close the protective cover 1 on the dispensing cap 2, we first engage the sleeve 6 on the part of the dispensing cap 2 opposite the container 3, without taking into account its angular position with respect to said cap.

Dans un deuxième temps, on referme l'un sur l'autre, le capuchon de distribution 2 et le capot de protection 1, en les faisant coulisser l'un par rapport à l'autre. Les bords 21 de la cheminée de distribution 19, qui délimitent l'ouverture 20̸, forment des saillies de conduite et se retrouvent en appui sur la paroi 4, puis sur les rampes de guidage 10̸. La cheminée 19 est alors guidée progressivement dans une gorge 12, jusqu'à ce que le picot 13 associé à ladite gorge 12 s'insère dans l'ouverture de distribution 20̸. Lors de cette manoeuvre, le manchon 6 descend coaxialement le long du capuchon de distribution 2. Ses possibilités de déplacements transverses sont diminuées au fur et à mesure qu'il passe sur le bouton poussoir 15, puis sur le bâti 14 et enfin sur le col 17, sur lequel il s'insère avec un léger serrage, après avoir été arrêté dans son déplacement axial par le rebord de la collerette 18.In a second step, the distribution cap 2 and the protective cover 1 are closed one on the other, by sliding them relative to one another. The edges 21 of the distribution chimney 19, which delimit the opening 20̸, form pipe protrusions and find themselves in abutment on the wall 4, then on the guide rails 10̸. The chimney 19 is then gradually guided in a groove 12, until the pin 13 associated with said groove 12 is inserted into the dispensing opening 20̸. During this maneuver, the sleeve 6 descends coaxially along the dispensing cap 2. Its possibilities of transverse displacements are reduced as and when it passes over the push button 15, then over the frame 14 and finally over the neck 17, on which it is inserted with a slight tightening, after having been stopped in its axial displacement by the flange of the collar 18.
