Description

La présente invention est relative à une pompe distributrice d'un type nouveau, du genre de celles qu'on utilise pour distribuer des produits liquides qui peuvent être très fluides (alcool), crémeux, ou plus ou moins visqueux (savon liquide, crème à raser, etc...)The present invention relates to a dispensing pump of a new type, of the kind used for dispensing liquid products which can be very fluid (alcohol), creamy, or more or less viscous (liquid soap, cream shave, etc ...)

On connait des pompes distributrices de ce genre, mais toutes présentent divers inconvénients.Distributor pumps of this kind are known, but all have various drawbacks.

Tout d'abord leur structure souvent complexe conduit à un prix de revient important. Ces pompes doivent donc pouvoir être réutilisées avec plusieurs recharges successives du produit à distribuer. Cela pose des problèmes d'asepsie lorsqu'on souhaite les utiliser par exemple au bloc opératoire dans un hôpital.First of all, their often complex structure leads to a significant cost price. These pumps must therefore be able to be reused with several successive refills of the product to be dispensed. This poses aseptic problems when you want to use them, for example in the operating room in a hospital.

De plus, la plupart des pompes connues laissent remonter l'air extérieur dans le produit après chaque utilisation. Il en résulte qu'elles ont tendance à se boucher par dessication du produit. Par ailleurs les rentrées d'air posent à nouveau un problème d'asepsie pour les utilisations médicales.In addition, most of the known pumps allow the outside air to rise in the product after each use. As a result, they tend to become clogged by drying the product. In addition, the air intake again poses a problem of asepsis for medical uses.

La présente invention a pour but de réaliser une pompe distributrice simple et peu coûteuse, qui satisfasse aux conditions d'asepsie les plus sévères. De plus, une telle pompe peut être réalisée sous forme jetable, ce qui permet de la fabriquer en même temps que la cartouche du produit à distribuer, et de la jeter en même temps qu'elle.The object of the present invention is to provide a simple and inexpensive dispensing pump which satisfies the most severe aseptic conditions. In addition, such a pump can be produced in disposable form, which makes it possible to manufacture it at the same time as the cartridge of the product to be dispensed, and to dispose of it at the same time as it.

Une autre pompe distributrice selon l'invention, destinée à être placée sous l'ouverture inférieure d'écoulement d'un récipient qui contient le produit liquide à distribuer, comprend un corps creux équipé à sa partie supérieure d'un clapet d'admission, et à sa partie inférieure d'un clapet de refoulement, et elle est caracterisée en ce que le corps est constitué par une paroi tubulaire en matière souple, tandis que le clapet d'admission se présente sous la forme d'une embouchure tubulaire en matière souple dont l'extrémité aval est aplatie pour définir une fente transversale située entre deux lèvres qui la maintiennent élastiquement fermée lorsque le clapet est au repos, alors qu'elles s'écartent à l'apparition d'un gradient de pression au sein du liquide à distribuer.Another dispensing pump according to the invention, intended to be placed under the lower flow opening of a container which contains the product liquid to be dispensed, comprises a hollow body equipped at its upper part with an inlet valve, and at its lower part with a discharge valve, and it is characterized in that the body consists of a tubular wall made of material flexible, while the intake valve is in the form of a tubular mouthpiece of flexible material whose downstream end is flattened to define a transverse slot located between two lips which keep it elastically closed when the valve is at rest, while they deviate at the appearance of a pressure gradient within the liquid to be dispensed.

Suivant une autre caractéristique de l'invention, le clapet de refoulement comprend une lèvre d'étanchéité annulaire dépassant vers l'intérieur d'une buse de refoulement, dans laquelle se trouve la jupe tubulaire déformable d'un tube obturateur. Au repos, cette jupe tubulaire est en position étanche dans la lèvre annulaire, cependant qu'à sa partie supérieure, un fond transversal la referme, le liquide ne circulant qu'extérieurement, autour de la jupe.According to another characteristic of the invention, the discharge valve comprises an annular sealing lip projecting towards the inside of a discharge nozzle, in which is the deformable tubular skirt of a obturator tube. At rest, this tubular skirt is in a sealed position in the annular lip, while at its upper part, a transverse bottom closes it, the liquid circulating only outside, around the skirt.

Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention :

  • - la figure 1 est une coupe longitudinale d'une pompe distributrice selon l'invention lorsqu'elle est au repos,
  • - les figures 2 et 3 illustrent deux phases de son fonctionnement,
  • - la figure 4 montre l'utilisation d'un distribuer mural équipé de la pompe selon l'invention,
  • - les figures 5 et 6 sont des vues en perspective montrant le clapet d'admission, rspectivement fermé, puis ouvert,
  • - la figure 7 montre le tube obturateur qui constitue le clapet de refoulement,
  • - les figures 8 et 9 montrent une variante où la pompe forme avec son flacon rigide déformable, un ensemble unique et jetable après usage.
The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention:
  • FIG. 1 is a longitudinal section of a dispensing pump according to the invention when it is at rest,
  • - Figures 2 and 3 illustrate two phases of its operation,
  • FIG. 4 shows the use of a wall-mounted dispenser equipped with the pump according to the invention,
  • FIGS. 5 and 6 are perspective views showing the inlet valve, respectively closed, then opened,
  • - Figure 7 shows the shutter tube which constitutes the discharge valve,
  • - Figures 8 and 9 show a variant where the pump forms with its rigid deformable bottle, a single set and disposable after use.

On a représenté sur les dessins un récipient ou cartouche 1 qui contient le liquide 2 à distribuer. Ce récipient possède à sa partie inférieure une ouverture d'écoulement 3 sous laquelle on adapte la pompe distributrice 4 selon l'invention. L'adaptation peut s'effectuer par tout moyen connu, par exemple par soudage, ou par vissage, d'un manchon fileté 5 comme on l'a supposé sur les Figures 1 à 3.There is shown in the drawings a container or cartridge 1 which contains the liquid 2 to be dispensed. This container has at its lower part a flow opening 3 under which the dispensing pump 4 according to the invention is adapted. The adaptation can be carried out by any known means, for example by welding, or by screwing, of a threaded sleeve 5 as was supposed in Figures 1 to 3.

La pompe 4 comprend un corps tubulaire 6 terminé, à son sommet, par une collerette 7 sur laquelle prend appui un clapet d'admission 8, et à sa partie inférieure par une buse de refroidissement 9.The pump 4 comprises a tubular body 6 terminated, at its top, by a collar 7 on which an intake valve 8 is supported, and at its lower part by a cooling nozzle 9.

A sa partie inférieure, la buse 9 possède une ouverture 10 pour l'éjection d'une dose 11 du produit 2.At its lower part, the nozzle 9 has an opening 10 for the ejection of a dose 11 of the product 2.

A mi-hauteur, elle est pourvue d'une lèvre annulaire 12 faisant saillie dans son espace intérieur.Halfway up, it is provided with an annular lip 12 projecting into its interior space.

A sa partie supérieure, elle possède un logement interne annulaire 13, prévu pour recevoir la collerette 14 équipant le sommet d'un tube obturateur 15.At its upper part, it has an annular internal housing 13, designed to receive the flange 14 fitted to the top of a shutter tube 15.

Le corps 6 de la pompe est réalisé en une matière moulée souple, que l'utilisateur peut écraser ente ses doigts, comme symbolisé en Figure 2 par les flèches 16.The body 6 of the pump is made of a flexible molded material, which the user can crush between his fingers, as symbolized in FIG. 2 by the arrows 16.

Le tube obturateur 15 pourvu d'une jupe cylindrique souple 17 fermée à son sommet par un fond transversal 18. Autour de celui-ci est disposée la collerette 14 dans laquelle sont découpées des lumières 19 pour laisser le produit 2 librement circuler autour de la jupe 17.The obturator tube 15 provided with a flexible cylindrical skirt 17 closed at its top by a transverse bottom 18. Around the latter is arranged the flange 14 in which are cut lights 19 to let the product 2 freely circulate around the skirt 17.

Au repos, après montage. le tube obturateur 15 est maintenu en place par la collerette 14 dans le logement 13 (Figure 3), cependant que la jupe 17 est serrée élastiquement par la lèvre d'étanchéité 12 qui l'entoure.At rest, after mounting. the obturator tube 15 is held in place by the flange 14 in the housing 13 (Figure 3), while the skirt 17 is elastically tightened by the sealing lip 12 which surrounds it.

Le clapet d'admission 8 est réalisé d'une pièce en une matière moulée souple. Il a la forme d'une collerette transversale annulaire 20 prolongée vers le bas par une embouchure tubulaire 23, aplatie à son extrémité aval où elle définit une fente transversale 21. Cette fente est située entre deux lèvres souples 22 qui, lorsque le clapet 8 est fermé, restent appliquées l'une contre l'autre de façon étanche (Figures 2 et 5).The inlet valve 8 is made in one piece from a flexible molded material. It has the shape of an annular transverse flange 20 extended downwards by a tubular mouth 23, flattened at its downstream end where it defines a transverse slot 21. This slot is located between two flexible lips 22 which, when the valve 8 is closed, remain tightly pressed against each other (Figures 2 and 5).

Lorsqu'au contraire un gradient de pression apparaît de l'amont vers l'aval au sein du produit 2, les lèvres 22 s'écartent et ouvrent la fente 21 qui laisse passer le produit 2 (Figures 3 et 6, flèche 24).When, on the contrary, a pressure gradient appears from upstream to downstream within the product 2, the lips 22 move apart and open the slot 21 which lets the product 2 through (Figures 3 and 6, arrow 24).

Le fonctionnement est le suivant :The operation is as follows:

Lorsque l'appareil 1,4 est au repos, les clapets 8 et 9,15 sont tous deux fermés (Figure 1) et la pompe 4 est pleine du produit 2 dans tout l'espace situé au-dessus de la lèvre d'étanchéité 12 de la buse 9. L'air ne peut donc pas pénétrer dans la pompe, ce qui garantit l'asepsie du produit 2 et empêche son éventuelle dessication.When the device 1,4 is at rest, the valves 8 and 9,15 are both closed (Figure 1) and the pump 4 is full of the product 2 in all the space located above the sealing lip 12 of the nozzle 9. The air cannot therefore enter the pump, which guarantees the asepsis of the product 2 and prevents its possible drying out.

Lorsque l'utilisateur écrase la paroi tubulaire du corps 6 (Figure 2, flèche 16), le clapet d'admission 8 reste hermétiquement fermé sous la poussée ascendante qui tend à refermer encore davantage les lèvres 22 l'une contre l'autre. Par contre, la poussée descendante exercée sur l'extérieur de la jupe 17 du tube obturateur 15 déforme vers l'intérieur cette jupe 17 qui s'écarte localement de la lèvre annulaire 12 et laisse fuir vers le bas la dose 11 de produit 2.When the user crushes the tubular wall of the body 6 (FIG. 2, arrow 16), the intake valve 8 remains hermetically closed under the upward thrust which tends to close the lips 22 even more against one another. On the other hand, the downward thrust exerted on the outside of the skirt 17 of the obturator tube 15 deforms inward this skirt 17 which deviates locally from the annular lip 12 and lets the dose 11 of product 2 leak downwards.

Quand l'utilisateur relâche la pompe 4 (Figure 3), son corps 6 revient élastiquement à sa position initiale (flèches 25), et la jupe 17 vient se refermer contre la lèvre d'étanchéité 12. Toute remontée d'air à travers la buse 9 se trouve ainsi empêchée.When the user releases the pump 4 (FIG. 3), his body 6 resiliently returns to its initial position (arrows 25), and the skirt 17 comes to close against the sealing lip 12. Any upflow of air through the nozzle 9 is thus prevented.

Par contre, le gradient de pression apparaissant entre l'amont et l'aval du clapet d'admission 8 écarte les lèvres 22 (Figures 3 et 6) pour laisser le produit 2 du récipient 1 pénétrer dans le corps 6 de la pompe 4 (flèche 24) qui se trouve ainsi rechargée, prête à un nouvel emploi.On the other hand, the pressure gradient appearing between the upstream and downstream of the intake valve 8 spreads the lips 22 (Figures 3 and 6) to let the product 2 of the container 1 penetrate into the body 6 of the pump 4 (arrow 24) which is thus recharged , ready for a new job.

On voit que la pompe selon l'invention peut être fabriquée pour un prix de revient très bas, si bien qu'on peut la prévoir sous forme jetable. En particulier, en fabrication, il est possible de l'intégrer à la cartouche 1 contenant le produit 2. L'ensemble peut alors être livré sous forme stérile, puis jeté après usage. Cela convient particulièrement bien pour les applications médicales et chirurgicales.It is seen that the pump according to the invention can be manufactured for a very low cost price, so that it can be provided in disposable form. In particular, during manufacturing, it is possible to integrate it into the cartridge 1 containing the product 2. The assembly can then be delivered in sterile form, then discarded after use. This is particularly suitable for medical and surgical applications.

Dans la variante illustrée sur les Figures 8 et 9, la pompe 4 est soudée définitivement à l'unique ouverture inférieure 3 d'un flacon 26. Ce dernier présente la particularité d'être réalisé en une matière plastique à la fois rigide et déformable. Ainsi, lorsqu'il est neuf et rempli du liquide 2, le flacon a une forme initiale bien définie, par exemple parallélepipédique (Figure 8), qui permet de l'adapter sur un distributeur mural. Par contre, au fur et à mesure que le liquide 2 est soutiré sans que l'air ne pénètre dans le flacon 26, celui-ci s'affaisse sur lui même par déformation à la façon d'une autre (Figure 9). On peut ainsi jeter l'ensemble 4 - 26 quand le flacon 26 a été vidé.In the variant illustrated in Figures 8 and 9, the pump 4 is permanently welded to the single lower opening 3 of a bottle 26. The latter has the distinction of being made of a plastic material that is both rigid and deformable. Thus, when it is new and filled with liquid 2, the bottle has a well-defined initial shape, for example parallelepipedal (Figure 8), which makes it possible to adapt it to a wall-mounted dispenser. On the other hand, as the liquid 2 is withdrawn without the air entering the bottle 26, the latter collapses on itself by deformation like another (Figure 9). It is thus possible to discard the assembly 4 - 26 when the bottle 26 has been emptied.
