Description

  • [0001] [0001]
    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, the kind of those used for dispensing liquid products which may be very fluid (alcohol), creamy, or more or less viscous (liquid soap, cream shave, etc ...)
  • [0002] [0002]
    On connait des pompes distributrices de ce genre, mais toutes présentent divers inconvénients. We know of pumps of this type, but all have various disadvantages.
  • [0003] [0003]
    Tout d'abord leur structure souvent complexe conduit à un prix de revient important. First of all their complex structure leads to a significant cost. Ces pompes doivent donc pouvoir être réutilisées avec plusieurs recharges successives du produit à distribuer. These pumps must be reused with successive recharges of the product to distribute. Cela pose des problèmes d'asepsie lorsqu'on souhaite les utiliser par exemple au bloc opératoire dans un hôpital. This poses problems when aseptic wishes to use the example in the operating room in a hospital.
  • [0004] [0004]
    De plus, la plupart des pompes connues laissent remonter l'air extérieur dans le produit après chaque utilisation. In addition, most known pumps let go outside air into the product after use. Il en résulte qu'elles ont tendance à se boucher par dessication du produit. The result is that they tend to become clogged by drying of the product. Par ailleurs les rentrées d'air posent à nouveau un problème d'asepsie pour les utilisations médicales. Furthermore the air flows again pose a problem for aseptic medical uses.
  • [0005] [0005]
    La présente invention a pour but de réaliser une pompe distributrice simple et peu coûteuse, qui satisfasse aux conditions d'asepsie les plus sévères. The present invention aims to achieve a simple and inexpensive dispensing pump, which meets the most stringent aseptic conditions. 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. Moreover, such a pump can be performed in disposable form, enabling the manufacture along with the product cartridge to distribute, and throw it at the same time.
  • [0006] [0006]
    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 dispenser pump according to the invention, intended to be placed under the lower opening of flow of a vessel which contains the liquid product to be dispensed, comprises a hollow body equipped at its upper part with an inlet valve, and its lower part with a discharge valve, and is characterized in that the body consists of a tubular wall of flexible material, while the inlet valve is in the form of a tubular mouth in flexible whose downstream end is flattened to define a transverse slit located between two lips which maintain it elastically closed when the valve is at rest, whereas they diverge at the appearance of a pressure gradient within the liquid to distribute.
  • [0007] [0007]
    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. According to another feature of the invention, the discharge valve comprises an annular sealing lip projecting inwardly from a discharge nozzle, is located in the deformable tubular skirt of a closure tube. 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. At rest, the tubular skirt is in sealing position in the annular lip, however, that its upper part, a transverse bottom closes it, the liquid flowing externally around the skirt.
  • [0008] [0008]
    Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention : The accompanying drawing, given by way of example, will better understand the characteristics of the invention:
    • - la figure 1 est une coupe longitudinale d'une pompe distributrice selon l'invention lorsqu'elle est au repos, - Figure 1 is a longitudinal section of a dispensing pump of the invention when at rest,
    • - les figures 2 et 3 illustrent deux phases de son fonctionnement, - Figures 2 and 3 illustrate two phases of its operation,
    • - la figure 4 montre l'utilisation d'un distribuer mural équipé de la pompe selon l'invention, - Figure 4 shows the use of a dispensing pump equipped with the wall according to the invention,
    • - les figures 5 et 6 sont des vues en perspective montrant le clapet d'admission, rspectivement fermé, puis ouvert, - Figures 5 and 6 are perspective views showing the inlet valve, rspectivement closed and then opened,
    • - la figure 7 montre le tube obturateur qui constitue le clapet de refoulement, - Figure 7 shows the shutter tube which forms the delivery valve,
    • - les figures 8 et 9 montrent une variante où la pompe forme avec son flacon rigide déformable, un ensemble unique et jetable après usage. - Figures 8 and 9 show a variant in which the pump forms with its deformable rigid bottle, a single, disposable unit after use.
  • [0009] [0009]
    On a représenté sur les dessins un récipient ou cartouche 1 qui contient le liquide 2 à distribuer. There is shown in the drawings a container or cartridge 1 containing the liquid 2 to be dispensed. Ce récipient possède à sa partie inférieure une ouverture d'écoulement 3 sous laquelle on adapte la pompe distributrice 4 selon l'invention. This container has at its bottom a discharge opening 3 in which the dispensing pump 4 is adapted according to the 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. Adaptation can be effected by any known means, for example by welding, or by screwing, with a threaded sleeve 5 as has been assumed in Figures 1 to 3.
  • [0010] [0010]
    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 of which rests an intake valve 8 and at its lower part by a cooling nozzle 9.
  • [0011] [0011]
    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 ejection of a dose 11 of product 2.
  • [0012] [0012]
    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.
  • [0013] [0013]
    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 top, it has an annular inner housing 13, adapted to receive the collar 14 fitted to the top of a closure tube 15.
  • [0014] [0014]
    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 flexible molded material, the user can overwrite ente his fingers, as symbolized in Figure 2 by the arrows 16.
  • [0015] [0015]
    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 shutter tube 15 provided with a flexible cylindrical skirt 17 closed at its top by a transverse bottom 18. Around thereof is arranged the collar 14 in which are cut slots 19 to leave the product 2 to move freely around the skirt 17.
  • [0016] [0016]
    Au repos, après montage. At rest, after assembly. 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. the shutter tube 15 is held in place by the collar 14 in the housing 13 (Figure 3), while the skirt 17 is elastically clamped by the sealing lip 12 that surrounds it.
  • [0017] [0017]
    Le clapet d'admission 8 est réalisé d'une pièce en une matière moulée souple. The intake valve 8 is made in one piece of flexible molded material. 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). It has the shape of an annular transverse flange 20 extended downwards by a tubular mouthpiece 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, are applied against one another in sealed manner (Figures 2 and 5).
  • [0018] [0018]
    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). In contrast, when a pressure gradient appears from upstream to downstream within the product 2, the lips 22 separate and open the slot 21 which passes the product 2 (Figures 3 and 6, 24 arrow).
  • [0019] [0019]
    Le fonctionnement est le suivant : The operation is as follows:
  • [0020] [0020]
    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 unit 1,4 is at rest, the flaps 8 and 9,15 are both closed (Figure 1) and the pump 4 is full of the product 2 in the entire space above the sealing lip 12 of the nozzle 9. the air therefore can not enter the pump, ensuring aseptic product 2 and prevents its eventual desiccation.
  • [0021] [0021]
    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. When the user overwrites the tubular wall of the body 6 (Figure 2, arrow 16), the intake valve 8 remains sealed by the upward thrust which tends to close it further lip 22 against one another. 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. For against, the downward thrust exerted on the outside of the skirt 17 of the closure tube 15 inwardly deforms the skirt 17 which deviates locally from the annular lip 12 and allows escape down the dose 11 of product 2.
  • [0022] [0022]
    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 (Figure 3), the body 6 returns elastically to its original position (arrow 25) and the skirt 17 comes to close it against the sealing lip 12. An ascent of air through the nozzle 9 is thus prevented.
  • [0023] [0023]
    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. By against the pressure gradient occurring between the upstream and downstream of the inlet valve 8 separates the lips 22 (Figures 3 and 6) to leave the product 2 of the container 1 into the body 6 of the pump 4 ( arrow 24) which is thus recharged, ready for a new job.
  • [0024] [0024]
    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. We see that the pump of the invention can be manufactured at a very low cost, so that one can predict in disposable form. 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. In particular, in manufacturing, it is possible to integrate it into the cartridge 1 containing the product 2. The assembly can then be supplied as sterile and discarded after use. Cela convient particulièrement bien pour les applications médicales et chirurgicales. This is particularly suitable for medical and surgical applications.
  • [0025] [0025]
    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. 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 particularity of being made of a plastic material that is both rigid and deformable. 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. Thus, when new and filled with the liquid 2, the bottle has an initial binary pattern, for example parallelepiped (Figure 8), which can be adapted on a wall dispenser. 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). For against, progressively as the liquid 2 is drawn without the air enters the bottle 26, it collapses on itself by deforming in the manner of another (Figure 9). On peut ainsi jeter l'ensemble 4 - 26 quand le flacon 26 a été vidé. One can thus throw the entire 4 to 26 when the bottle 26 has been emptied.
