Abstract
Description
La présente invention a pour objet un dispositif de dosage d'un produit liquide ou semi-pâteux contenu dans un tube souple permettant de délivrer une dose du produit chaque fois qu'on exerce une pression sur le tube souple, et agencé pour empecher toute pénétration d'air dans le tube risquant d'affecter les propriétés du produit contenu. The subject of the present invention is a device for dosing a liquid or semi-pasty product contained in a flexible tube making it possible to deliver a dose of the product each time that a pressure is exerted on the flexible tube, and designed to prevent any penetration air in the tube which could affect the properties of the product contained.
A cet effet, ce tube comporte à sa partie supérieure un manchon, venu de fabrication avec lui, ou indépendant et fixé de toute manière appropriée, telle que soudage ou vissage par exemple, avec un orifice latéral de sortie du produit au-dessous de son fond, ledit fond étant percé d'une petite ouverture axiale, à travers laquelle peut coulisser une tige de piston, entre deux positions extrêmes, avec une rondelle librement coulissante sur elle, entre le piston en position basse et un épaulement de la tige de piston en position haute, le piston et la rondelle constituant continûment, successivement ou simultanément, des joints d'étanchéité dans le manchon, lors de leur coulissement axial, l'un d'eux étant constamment dans la douille, au-dessous de son orifice de sortie, l'ensemble étant agencé de façon qu'en posi tion extrême basse de la tige du piston, le produit puisse passer autour du piston et pénétrer dans le manchon jusqu'à la rondelle qui en empêche la sortie vers le haut, en position intermédiaire, une dose de produit soit maintenue dans le manchon entre le piston et la rondelle, et qu'en se rapprochant de la position extrême haute, la rondelle dégage l'ouverture latérale du manchon à travers laquelle le produit peut commencer à sortir du manchon, et que la dose complète du produit soit éva--- cuée quand la tige du piston atteint sa-position extrême haute. For this purpose, this tube comprises at its upper part a sleeve, which has come from manufacturing with it, or independent and fixed in any suitable manner, such as welding or screwing for example, with a lateral outlet for the product to exit below its bottom, said bottom being pierced with a small axial opening, through which a piston rod can slide, between two extreme positions, with a freely sliding washer on it, between the piston in the low position and a shoulder of the piston rod in the high position, the piston and the washer continuously, successively or simultaneously, forming seals in the sleeve, during their axial sliding, one of them being constantly in the sleeve, below its orifice outlet, the assembly being arranged so that in the extreme low position of the piston rod, the product can pass around the piston and penetrate the sleeve up to the washer which prevents its exit upwards, positively Intermediate ion, a dose of product is maintained in the sleeve between the piston and the washer, and as it approaches the extreme high position, the washer releases the lateral opening of the sleeve through which the product can begin to exit the sleeve, and that the full dose of the product is evacuated when the piston rod reaches its extreme high position.
Le dessin annexé montre à titre d'exemple un mode de réalisation du dispositif suivant la présente invention. The accompanying drawing shows by way of example an embodiment of the device according to the present invention.
Les figures 1 à 4 sont des vues en coupe longitudinales respectivement - en position extrême basse - en position intermédiaire basse, en position intermédiaire haute et en position extrême haute. Figures 1 to 4 are views in longitudinal section respectively - in the extreme low position - in the low intermediate position, in the high intermediate position and in the extreme high position.
Le dispositif représenté comporte un manchon 1, avec un orifice latéral 2 de sortie du produit 3 contenu dans le tube, et dont le fond 4 est percé d'une petite ouverture 5, à travers laquelle peut coulisser une tige de piston 6. The device shown comprises a sleeve 1, with a lateral orifice 2 for the outlet of the product 3 contained in the tube, and the bottom 4 of which is pierced with a small opening 5, through which a piston rod 6 can slide.
Un piston 7 est fixé à la partie inférieure de la tige de piston 6,et une rondelle mobile 8, munie de lèvres d'étanchéité 9, peut coulisser librement sur la tige de piston 6, entre le piston 7 et un épaulement 10 de la tige de piston, constitué par une différence des diamètres de sa partie haute et de sa partie basse. A piston 7 is fixed to the lower part of the piston rod 6, and a movable washer 8, provided with sealing lips 9, can slide freely on the piston rod 6, between the piston 7 and a shoulder 10 of the piston rod, constituted by a difference in the diameters of its upper part and its lower part.
La tige de piston 6 est en position extrême basse, comme le montre la figure 1, quand sa tête proéminente ll vient buter contre les bords de l'ouverture axiale 5 du fond du manchon 1; le piston 7 est alors sorti du manchon et le produit 3 contenu dans le tube peut circuler autour de lui pour pénétrer dans le manchon. The piston rod 6 is in the extreme low position, as shown in FIG. 1, when its protruding head ll abuts against the edges of the axial opening 5 of the bottom of the sleeve 1; the piston 7 is then taken out of the sleeve and the product 3 contained in the tube can circulate around it to penetrate the sleeve.
La tige de piston 6 est en position extrême haute, comme le montre la figure 4, quand la rondelle 8, elle-même en position haute, en butée contre l'épaulement 10 de la tige de piston 6, vient buter contre le fond 2 du manchon 1, et que le piston 7 vient lui-même buter contre la rondelle 8. The piston rod 6 is in the extreme high position, as shown in FIG. 4, when the washer 8, itself in the high position, in abutment against the shoulder 10 of the piston rod 6, abuts against the bottom 2 of the sleeve 1, and that the piston 7 itself abuts against the washer 8.
Le fonctionnement est le suivant
Le dispositif étant dans la position extrême basse représenté à la figure 1, si l'on exerce une pression sur le tube souple, le produit contenu contourne le piston 7 et vient exercer une pression sur la rondelle 8, qui le maintient dans le manchon qu'elle obture vers le haut.The operation is as follows
The device being in the extreme low position shown in FIG. 1, if pressure is exerted on the flexible tube, the product contained bypasses the piston 7 and exerts pressure on the washer 8, which keeps it in the sleeve that 'it closes up.
La rondelle 8, en butée sur l'épaulement 10 de la tige de piston 6, entraîne donc dans son coulissement vers le haut tout l'équipage mobile, et le piston 7 vient obturer la partie inférieure du manchon, comme le montre la figure 2, et maintenir énfermée une dose du produit entre saface supérieure, la face inférieure de la rondelle 8,qui n'a pas encore dégagé l'orifice 2 de sortiedu produit, la tige du piston 5, et la douille 1. The washer 8, in abutment on the shoulder 10 of the piston rod 6, therefore causes the movable assembly to slide upwards, and the piston 7 comes to close off the lower part of the sleeve, as shown in FIG. 2 , and keep a dose of the product enclosed between its upper surface, the lower face of the washer 8, which has not yet cleared the orifice 2 of the product outlet, the piston rod 5, and the sleeve 1.
La pression du produit s'exerce ensuite sur la face inférieure du piston 7, comme le montrent les figures 2 et 3; la rondelle 8 dégage l'orifice 2 de sortie du produit qui peut commencer à être chassé à travers ledit orifice. The product pressure is then exerted on the underside of the piston 7, as shown in Figures 2 and 3; the washer 8 releases the orifice 2 for the outlet of the product which can begin to be driven through said orifice.
Quand l'équipage mobile arrive dans la position extrême haute, montrée à la figure 4, toute la dose du produit contenu entre le piston 7 et la rondèlle 8, contre laquelle il est venu buter, a été expulsee à travers l'orifice de sortie 2. When the moving part arrives in the extreme high position, shown in FIG. 4, the entire dose of the product contained between the piston 7 and the washer 8, against which it has come to abut, has been expelled through the outlet orifice 2.
Il suffit alors d'exercer une poussée vers le bas sur la tête proéminente 11 de la tige de piston 6 pour faire passer tout l'équipage mobile de la position extreme haute, montrée à la figure 4, à la position extrême basse, montrée a la figure 1, dans laquelle il est prêt àpréparer et à expulser une nouvelle dose de produit, par une simple pression exercée sur le tube souple. It then suffices to exert a downward push on the protruding head 11 of the piston rod 6 to move the entire moving assembly from the extreme high position, shown in FIG. 4, to the extreme low position, shown a Figure 1, in which it is ready to prepare and expel a new dose of product, by a simple pressure exerted on the flexible tube.
Pour diminuer autant que possible l'amplitude dela cpurse de l'équipage mobile pour une opération de prélèvement d'une dose, la différence des nveauxde la face supérieure du piston 7 et de la face inférieure de la rondelle 8 est à peine inférieure à la différence de niveaux entre le niveau inférieur du manchon 1 et le niveau inférieur de son orifice de sortie latéral 2. To reduce as much as possible the amplitude dela cpurse of the mobile assembly for an operation of taking a dose, the difference of the levels of the upper face of the piston 7 and of the lower face of the washer 8 is hardly less than the difference in levels between the lower level of the sleeve 1 and the lower level of its lateral outlet orifice 2.
I1 est bien entendu que le mode de réalisation de l'invention qui a été décrit ci-dessus en référence au dessin annexé a été donné à titre purement indicatif et nullement limitatif et que de nombreuses modifications pourraient être apportées sans qu'on s'écarte pour autant du cadre de la présente invention. It is understood that the embodiment of the invention which has been described above with reference to the appended drawing has been given for information only and is in no way limitative and that numerous modifications could be made without departing from the scope. however within the scope of the present invention.
L'orifice de sortie 2 du produit a été représenté s'étendant jusque dans le fond 4 du manchon 1, pour faciliter le démoulage, mais il pourrait être réalisé tout autrement; il pourrait notamment être de dimension suffisamment réduite pour que le produit soit éjecté sous pression; l'équipage mobile pourrait être bloqué par tous moyens appropriés en position extrême basse, pour éviter toute possibilité de fonctionnement intempestif; la tige de piston pourrait comporter à sa partie supérieure un capuchon dont la jupe occulterait en position basse l'orifice de sortie; ce capuchon pourrait se visser sur une extremite du tubeRqui qui serait filetée à cet effet; des rainures péripheri- ques longitudinales ou un clapet pourraient être prévus sur le piston pour faciliter son enfqncement, après expulsion d'une do si la souplesse du tube n'était pas suffisante pour absorber la pression accrue qui en résulte pour le produit contenu. The outlet orifice 2 of the product has been shown extending as far as the bottom 4 of the sleeve 1, to facilitate demolding, but it could be done quite differently; in particular, it could be of sufficiently small size for the product to be ejected under pressure; the moving part could be blocked by any appropriate means in the extreme low position, to avoid any possibility of inadvertent operation; the piston rod could comprise at its upper part a cap whose skirt would obscure the outlet orifice in the low position; this cap could be screwed onto one end of the tube R which would be threaded for this purpose; longitudinal peripheral grooves or a valve could be provided on the piston to facilitate its insertion, after expulsion of a do if the flexibility of the tube was not sufficient to absorb the resulting increased pressure for the product contained.
