Description

La présente invention est relative à un perfectionnement du récipient distributeur de substance visqueuse, tel que décrit et représenté dans la demande de brevet français n° 87 10053 déposée le 16 Juillet 1987 et publiée le 20 Janvier 1989 sous le n° 2618127, qui correspond à la demande de brevet européen déposée le 15 juillet 1988 sous le n°88401847.4. Le récipient décrit dans ce document antérieur comprend comme représenté sur la figure 1 annexée un corps de récipient 1 muni d'un réservoir 2 contenant la substance à distribuer et d'une tête de distribution 3 susceptible d'être commandée à l'ouverture ou à la fermeture, le réservoir 2 étant constitué en matériau souple et le récipient comprenant en outre des moyens 20, 23 de pression permettant d'exercer sur le réservoir 2, en présence de substance, une pression permanente, afin de permettre la distribution de la substance sur seule commande à l'ouverture de la tête de distribution 3.The present invention relates to an improvement of the viscous substance dispensing container, as described and represented in French patent application No. 87 10053 filed on July 16, 1987 and published on January 20, 1989 under No. 2618127, which corresponds to European patent application filed on July 15, 1988 under No. 88401847.4. The container described in this prior document comprises, as shown in FIG. 1 attached, a container body 1 provided with a reservoir 2 containing the substance to be dispensed and with a dispensing head 3 capable of being controlled upon opening or closing, the reservoir 2 being made of flexible material and the container further comprising pressure means 20, 23 making it possible to exert permanent pressure on the reservoir 2, in the presence of substance, in order to allow the distribution of the substance on single command when opening the dispensing head 3.

Le récipient précédemment décrit donne satisfaction du point de vue de son fonctionnement.The container described above is satisfactory from the point of view of its operation.

Toutefois on a constaté, au cours d'essais de développement et de perfectionnement du récipient précité, qu'il était opportun de prévoir, en fonction de la puissance de restitution et de distributin de la substance à distribuer, des moyens de pression exerçant leur effet de manière différente.However, it has been found, during tests for development and improvement of the aforementioned container, that it was expedient to provide, as a function of the power of restitution and distribution of the substance to be distributed, pressure means exerting their effect. in a different way.

Le perfectionnement, selon la présente invention, au récipient distributeur de substance visqueuse selon la demande de brevet français n° 87 10053 déposée le 16 Juillet 1987 est remarquable en ce que les moyens élastiques, prenant appui sur la paroi interne du corps de récipient, comprennent une première et une deuxième lames élastiques formant ressort entre les faces internes desquelles le réservoir constitué en matériau souple est placé et des moyens de rappel externes agissant sur la face externe des ressorts.The improvement, according to the present invention, in the viscous substance distributor container according to French patent application No. 87 10053 filed on July 16, 1987 is remarkable in that the elastic means, bearing on the internal wall of the container body, include first and second elastic blades forming a spring between the internal faces of which the reservoir made of flexible material is placed and external return means acting on the external face of the springs.

Le récipient selon l'invention, en fonction de la force des moyens de rappel externes, trouve application à la distribution de substances crêmeuses, soit à grande viscosité, conditionnées sous une pression de 800g/cm², ou de substances plus fluides telles que les émulsions.The container according to the invention, depending on the strength of the external return means, finds application in the distribution of creamy substances, either of high viscosity, conditioned under a pressure of 800 g / cm², or of more fluid substances such as emulsions. .

Le récipient selon l'invention sera décrit plus en détail dans la description ci-après et dans les dessins annexés sur lesquels :

  • - la figure 1 représente une vue schématique en coupe longitudinale d'un récipient distributeur connu tel que décrit dans la demande de brevet français n° 87 10053,
  • - la figure 2a représente, selon une vue en coupe transversale correspon­dant au plan de coupe A-A de la figure 1, un mode de réalisation de l'invention dans le cas où le réservoir constitué par un matériau élastique est vide,
  • - la figure 2b représente le même mode de réalisation dans le cas où le réservoir en matériau élastique est partiellement rempli.
The container according to the invention will be described in more detail in the description below and in the accompanying drawings in which:
  • FIG. 1 represents a schematic view in longitudinal section of a known dispensing container as described in French patent application No. 87 10053,
  • FIG. 2a represents, according to a cross-sectional view corresponding to the section plane AA of FIG. 1, an embodiment of the invention in the case where the reservoir constituted by an elastic material is empty,
  • - Figure 2b shows the same embodiment in the case where the reservoir of elastic material is partially filled.

Comme représenté sur la figure 1 annexée, le récipient distributeur de substance visqueuse auquel s'applique l'invention comporte un corps de récipient 1, muni d'un réservoir 2 contenant la substance visqueuse à distribuer. Le récipient distributeur de substance visqueuse comporte également une tête de distribution 3, susceptible d'être commandée à l'ouverture ou à la fermeture, afin d'assurer la distribution de la substance précitée ou son stockage dans le récipient.As shown in Figure 1 attached, the viscous substance dispensing container to which the invention applies comprises a container body 1, provided with a reservoir 2 containing the viscous substance to be dispensed. The viscous substance dispensing container also comprises a dispensing head 3, capable of being controlled on opening or closing, in order to ensure the distribution of the aforementioned substance or its storage in the container.

Le réservoir noté 2, est constitué en matériau souple, et des moyens notés 20, 23 désignés par moyens de pression, permettent d'exercer sur le réservoir 2, en présence de substance, une pression permanente. Les moyens de pression précités associés au réservoir en matériau souple permettent sur seule commande à l'ouverture de la tête de distribution 3, la distribution de la substance visqueuse à distribuer.The tank denoted 2, is made of flexible material, and means denoted 20, 23 designated by pressure means, make it possible to exert on the reservoir 2, in the presence of substance, a permanent pressure. The aforementioned pressure means associated with the flexible material reservoir allow, on a single command when the dispensing head 3 is opened, the distribution of the viscous substance to be dispensed.

Le réservoir 2 est avantageusement constitué par un matériau souple élastique constituant la ou les parois du réservoir. Ces parois lors du chargement en substance visqueuse à distribuer sont mises en tension mécanique, et les moyens de pression 20 sont dans ce cas, constitués de manière non limitative par la tension élastique des parois.The tank 2 is advantageously constituted by a flexible elastic material constituting the wall or walls of the tank. These walls during the loading of viscous substance to be dispensed are put under mechanical tension, and the pressure means 20 are in this case, constituted in a nonlimiting manner by the elastic tension of the walls.

Le récipient distributeur de substance visqueuse, selon l'invention, sera maintenant décrit en liaison avec les figures 2a et 2b.The viscous substance dispensing container according to the invention will now be described in connection with FIGS. 2a and 2b.

Selon la figure 2a, laquelle représente une vue en coupe transversale du distributeur selon la coupe AA de la figure 1, les moyens élastiques 23, prenant appui sur la paroi interne du corps de récipient 1, comprennent une première 230 et une deuxième 231 lames élastiques formant ressort entre les faces internes desquelles le réservoir 2 constitué en matériau souple est placé. En outre, des moyens 2400 jouent le rôle de moyens de rappel externes agissant sur la face externe des ressorts.According to FIG. 2a, which represents a cross-sectional view of the dispenser according to section AA of FIG. 1, the elastic means 23, bearing on the internal wall of the container body 1, comprise a first 230 and a second 231 elastic blades forming a spring between the internal faces of which the reservoir 2 made of flexible material is placed. In addition, means 2400 play the role of external return means acting on the external face of the springs.

Sur la figure 2a on a représenté la première 230 et la deuxième 231 lames élastiques entourant le réservoir 2 constitué en matériau souple, lorsque celui-ci est totalement vide.FIG. 2a shows the first 230 and the second 231 elastic blades surrounding the reservoir 2 made of flexible material, when the latter is completely empty.

Selon le mode de réalisation des figures 2a et 2b les moyens de rappel externes sont avantageusement constitués par une gaine élastique 2400, laquelle est rapportée sur la face externe des lames élastiques 230 et 231.According to the embodiment of FIGS. 2a and 2b, the external return means are advantageously constituted by an elastic sheath 2400, which is attached to the external face of the elastic blades 230 and 231.

Selon une caractéristique avantageuse du mode de réalisation des figures 2a et 2b, la gaine élastique 2400 est tendue sur les lames élastiques 230, 231 lorsque le réservoir 2 constitué en matériau élastique étant vide, les deux lames élastiques 230, 231 présentent un écartement minimum. Pour assurer le montage de l'ensemble constitué par le réservoir 2 constitué en matériau élastique contenu dans l'espace constitué par les première 230 et deuxième lames élastiques 231 et par la gaine 2400, la gaine est déformée transversalement de façon à présenter une dimension d'élongation supérieure à la dimension des lames 230 et 231, le sous ensemble constitué par les lames élastiques 230, 231 et le réservoir 2 constitué en matériau élastique étant alors introduit dans la gaine dilatée. Après disposition convenable relative du sous ensemble précité dans la gaine, la gaine est relâchée et celle-ci vient s'adapter directement sur les lames élastiques 230, 231, sur la paroi externe de ces dernières.According to an advantageous characteristic of the embodiment of FIGS. 2a and 2b, the elastic sheath 2400 is stretched over the elastic blades 230, 231 when the reservoir 2 made of elastic material is empty, the two elastic blades 230, 231 have a minimum spacing. To ensure the assembly of the assembly constituted by the reservoir 2 made of elastic material contained in the space constituted by the first 230 and second elastic blades 231 and by the sheath 2400, the sheath is deformed transversely so as to have a dimension d elongation greater than the size of the blades 230 and 231, the subassembly consisting of the elastic blades 230, 231 and the reservoir 2 made of elastic material then being introduced into the expanded sheath. After a suitable relative arrangement of the abovementioned sub-assembly in the sheath, the sheath is released and the latter comes to adapt directly to the elastic blades 230, 231, on the external wall of the latter.

Bien entendu, la gaine élastique 2400 peut être formée par un manchon cylindrique en caoutchouc dont le diamètre, en l'absence de déformation, est inférieur au diamètre du corps de récipient 1. De préférence, on pourra choisir un manchon en caoutchouc de qualité moyenne, tel qu'un manchon de caoutchouc synthétique puisque, bien entendu, la substance visqueuse à distribuer n'entre pas en contact avec ce dernier.Of course, the elastic sheath 2400 can be formed by a cylindrical rubber sleeve whose diameter, in the absence of deformation, is less than the diameter of the container body 1. Preferably, it is possible to choose a rubber sleeve of medium quality. , such as a synthetic rubber sleeve since, of course, the viscous substance to be dispensed does not come into contact with the latter.

On notera également que le mode de réalisation représenté sur les figures 2a et 2b présente l'avantage d'isoler les lames élastiques 230, 231 en acier du contact du corps de récipient 1, ce contact devant être notamment évité lorsque le corps de récipient 1 est constitué par de l'aluminium, afin d'éviter les interactions par électropositivité entre l'aluminium et l'acier.It will also be noted that the embodiment shown in FIGS. 2a and 2b has the advantage of isolating the elastic blades 230, 231 made of steel from the contact of the container body 1, this contact having to be notably avoided when the container body 1 is made of aluminum, in order to avoid interactions by electropositivity between aluminum and steel.

Le mode de réalisation, tel quc représenté en figures 2a et 2b, est ainsi très économique dans la mesure ou il permet de prévoir l'utilisation de lames élastiques 230, 231 de faible épaisseur, ce qui permet de réduire les coûts de fabrication en conséquence. La puissance de restitution de la substance visqueuse est ainsi liée, non seulement à l'élasticité des ressorts et à leur qualité mécanique, mais aussi à celle du manchon 2400. Bien entendu, la puissance de restitution de la substance visqueuse peut être ajustée par le choix de l'épaisseur des lames élastiques 230, 231, ainsi que de l'élasticité et de la tension de la gaine 2400. Le mode de réalisation représenté aux figures 2a et 2b, est notamment adapté pour la distribution d'émulsions de type de substance visqueuse se présentant sous forme de lait, genre lait de toilette ou même de produits à caractère médicamenteux, tels que la biafine, distribués par les Laboratoi­res MEDIX en France et par ses représentants.The embodiment, as shown in FIGS. 2a and 2b, is thus very economical insofar as it makes it possible to provide for the use of elastic blades 230, 231 of small thickness, which makes it possible to reduce the manufacturing costs as a result. . The rendering power of the viscous substance is thus linked, not only to the elasticity of the springs and their mechanical quality, but also to that of the sleeve 2400. Of course, the rendering power of the viscous substance can be adjusted by the choice of the thickness of the elastic blades 230, 231, as well as the elasticity and the tension of the sheath 2400. The embodiment shown in FIGS. 2a and 2b is particularly suitable for the distribution of emulsions of the viscous substance in the form of milk, such as toilet milk or even medicinal products, such as biafine, distributed by Laboratoires MEDIX in France and by its representatives.

On a ainsi décrit un récipient distributeur de substance visqueuse particulièrement performant dans la mesure où une action externe au ressort ou lames élastiques permet finalement, en fonction de l'application considérée, de moduler la puissance de distribution de la substance visqueuse considérée.A particularly efficient viscous substance dispensing container has thus been described in so far as an action external to the spring or elastic blades finally makes it possible, depending on the application considered, to modulate the dispensing power of the viscous substance considered.
