Definitions
- the present invention relates to a dosing tube for the precise distribution of doses of a pasty product.
- Dosing tubes which comprise an elongated cylindrical body closed at one of its ends by a transverse wall pierced with an outlet for the pasty product and which carries, at its other end, a mounted control button coaxially in rotation, this control button being integral with a threaded axial rod which is screwed into an internal sliding piston.
- a dosing tube of the aforementioned type is described, for example, in patents US-2,485,467 and FR-A-2,312,422.
- the body of this metering tube can have a circular or non-circular cross section, in particular elliptical or polygonal.
- the present invention aims to remedy these drawbacks by providing a dosing tube of particularly simple design and taking advantage of the non-circular cross section of the body to allow high accuracy in the distribution of doses of pasty product to be obtained.
- the cross section of the body and of the control button can be curved, for example oval or elliptical, or in the shape of a regular polygon such as equilateral triangle, square, etc. Because the control button has the same non-circular cross section (in terms of shape and size) as that of the body, the passage of this control button between two positions in each of which it is aligned with the body, is translated by a rotation of the control button a fraction of a turn relative to the body, a fraction which is well determined angularly and which in turn causes a well-determined longitudinal displacement of the internal piston ensuring the delivery of a precise elementary dose of pasty product through the outlet.
- the dosing tube shown in Figures 1 to 3 comprises a cylindrical body 1 closed at one of its ends by a transverse wall 2 in the central part of which is formed an outlet orifice 3.
- This body 1 contains a product pasty 4 which is forced through the outlet 3 by an internal piston 5 mounted to slide.
- This piston 3 is pierced with a tapped central hole 6 which is crossed by an axial threaded rod 7.
- This threaded rod 7 comes out of the body 1, through a front wall 8 opposite the front wall 2 pierced with the orifice 3 , and it is integral, at its outer end, with a transverse control button 9.
- the rotation of this button 9 consequently causes that of the threaded rod 7 and correspondingly the sliding of the internal piston 5, in order to repress the pasty product at through the outlet 3.
- the body 1 and the control button 9 have a non-circular cross section but which has a center of symmetry on the longitudinal axis zz 'of the body 1 and the button 9.
- This cross section has substantially the shape of an ellipse in the embodiment shown in Figures 1 to 3. If we consider the top view shown. by FIG. 3, we see that the major axis xx 'of the elliptical cross section of the control button 9 is found to be perpendicular to the major axis yy' of the elliptical cross section of the body 1. This corresponds to the middle of the elementary rotation of 180 ° of the control button 9 between the two positions in which it is located.
- the elliptical cross-section control button 9 is located exactly in line with the. elongated body with elliptical cross section 1.
- the elliptical cross section of the control button 9 can be strictly identical to that of the body 1 or slightly larger or smaller while remaining homothetic.
- FIGS 4 and 5 illustrate an alternative embodiment of the dosing tube according to the invention in which the body 11 and the control button 12 each have a cross section in the form of an equilateral triangle.
- each elementary rotation of the control button 12, relative to the body 11, between a position in which it is aligned with the body 11 and a following alignment position corresponds to an angle of 120 °.
- the elementary dose leaving the dosing tube corresponds to an elementary displacement of the internal piston 5 driven by a third of a turn of the control button 12.
- the dosing tube comprises a body 13 and a control button 14 can be turned by quarter of a turn, each quarter of a turn corresponding to a precise dose of pasty product leaving the dosing tube. .

Description
La présente invention concerne un tube doseur pour la distribution précise de doses d'un produit pâteux.The present invention relates to a dosing tube for the precise distribution of doses of a pasty product.
On connaît déjà des tubes doseurs qui comportent un corps allongé cylindrique fermé, à l'une de ses extrémités, par une paroi transversale percée d'un orifice de sortie du produit pâteux et qui porte, à son autre extrémité, un bouton de commande monté coaxialement à rotation, ce bouton de commande étant solidaire d'une tige axiale filetée qui est vissée dans un piston coulissant interne. Un tube doseur du type précité est décrit, par exemple, dans les brevets US-2 485 467 et FR-A-2 312 42Ô. Le corps de ce tube doseur peut avoir une section droite circulaire ou non, notamment elliptique ou polygonale. Dans un tel tube doseur la rotation du bouton de commande se traduit par un coulissement du piston en direction de l'orifice de sortie du tube doseur si bien que chaque rotation du bouton de commande entraîne la sortie d'une certaine quantité de produit pâteux à travers l'orifice percé dans la paroi frontale du tube doseur.Dosing tubes are already known which comprise an elongated cylindrical body closed at one of its ends by a transverse wall pierced with an outlet for the pasty product and which carries, at its other end, a mounted control button coaxially in rotation, this control button being integral with a threaded axial rod which is screwed into an internal sliding piston. A dosing tube of the aforementioned type is described, for example, in patents US-2,485,467 and FR-A-2,312,422. The body of this metering tube can have a circular or non-circular cross section, in particular elliptical or polygonal. In such a dosing tube the rotation of the control button results in a sliding of the piston in the direction of the outlet orifice of the dosing tube so that each rotation of the control button causes the exit of a certain quantity of pasty product at through the hole drilled in the front wall of the dosing tube.
Dans certaines applications il est nécessaire que l'utilisateur puisse contrôler avec précision la quantité de produit sortant du tube doseur chaque fois qu'il fait tourner le bouton de commande. On a déjà envisagé de prévoir, à cet effet, une fenêtre longitudinale transparente, avec une graduation, pour permettre de repérer le déplacement du piston entre deux repères successifs. Toutefois une telle façon de faire n'assure pas un dosage très précis et par ailleurs la fabrication d'un tel tube doseur est rendue plus complexe du fait de la nécessité d'avoir à prévoir cette fenêtre transparente.In some applications it is necessary for the user to be able to precisely control the amount of product leaving the dosing tube each time the control knob is turned. It has already been envisaged to provide, for this purpose, a transparent longitudinal window, with a graduation, to enable the displacement of the piston to be located between two successive marks. However, such a procedure does not ensure very precise dosing and, moreover, the manufacture of such a dosing tube is made more complex due to the need to have to provide this transparent window.
La présente invention vise à remédier à ces inconvénients en procurant un tube doseur de conception particulièrement simple et tirant parti de la section droite non-circulaire du corps pour permettre d'obtenir une grande précision dans la distribution des doses de produit pâteux.The present invention aims to remedy these drawbacks by providing a dosing tube of particularly simple design and taking advantage of the non-circular cross section of the body to allow high accuracy in the distribution of doses of pasty product to be obtained.
A cet effet, ce tube doseur pour la distribution de doses d'un produit pâteaux, comportant un corps allongé contenant le produit pâteux, ce corps allongé présentant une section droite non circulaire ayant un centre de symétrie sur l'axe longitudinal du corps, un orifice de sortie du produit pâteux prévu dans la paroi du corps, à une extrémité de celui-ci, un bouton de commande monté à rotation sur le corps, à l'extrémité de celui-ci qui est opposée à celle présentant l'orifice de sortie, un piston interne de même forme que celle de la section droite du corps et mobile à coulissement dans le corps, et des moyens pour transformer la rotation du bouton de commande en une translation du piston interne est caractérisé en ce que le bouton de commande a, en section droite, la même forme non circulaire que la section droite non circulaire du corps et sensiblement les mêmes dimensions que celles de cette section droite.To this end, this dosing tube for dispensing doses of a pastry product, comprising an elongated body containing the pasty product, this elongated body having a non-circular cross section having a center of symmetry on the longitudinal axis of the body, a outlet for the pasty product provided in the wall of the body, at one end thereof, a control button mounted for rotation on the body, at the end thereof which is opposite to that having the orifice outlet, an internal piston of the same shape as that of the straight section of the body and movable to slide in the body, and means for transforming the rotation of the control button into a translation of the internal piston is characterized in that the control button has, in cross section, the same non-circular shape as the non-circular cross section of the body and substantially the same dimensions as those of this cross section.
La section droite du corps et du bouton de commande peut être courbe, par exemple ovale ou elliptique, ou en forme de polygone régulier tel que triangle équilatéral, carré, etc. Du fait que le bouton de commande présente la même section droite non circulaire (du point de vue forme et dimension) que celle du corps, le passage de ce bouton de commande entre deux positions dans chacune desquelles il se trouve aligné avec le corps, se traduit par une rotation du bouton de commande d'une fraction de tour par rapport au corps, fraction qui est bien déterminée angulaire- ment et qui entraîne à son tour un déplacement longitudinal bien déterminé du piston interne assurant le refoulement d'une dose élémentaire précise du produit pâteux a travers l'orifice de sortie.The cross section of the body and of the control button can be curved, for example oval or elliptical, or in the shape of a regular polygon such as equilateral triangle, square, etc. Because the control button has the same non-circular cross section (in terms of shape and size) as that of the body, the passage of this control button between two positions in each of which it is aligned with the body, is translated by a rotation of the control button a fraction of a turn relative to the body, a fraction which is well determined angularly and which in turn causes a well-determined longitudinal displacement of the internal piston ensuring the delivery of a precise elementary dose of pasty product through the outlet.

Le tube doseur représenté sur les figures 1 à 3 comprend un corps cylindrique 1 fermé, à l'une de ses extrémités, par une paroi transversale 2 dans la partie centrale de laquelle est ménagé un orifice de sortie 3. Ce corps 1 contient un produit pâteux 4 qui est forcé à travers l'orifice de sortie 3 par un piston interne 5 monté à coulissement. Ce piston 3 est.percé d'un trou central taraudé 6 qui est traversé par une tige filetée axiale 7. Cette tige filetée 7 sort du corps 1, à travers une paroi frontale 8 oppose à la paroi frontale 2 percée de l'orifice 3, et elle est solidaire, à son extrémité externe, d'un bouton de commande transversal 9. La rotation de ce bouton 9 entraîne par conséquent celle de la tige filetée 7 et corrélativement le coulissement du piston interne 5, pour refouler le produit pâteux à travers l'orifice de sortie 3.The dosing tube shown in Figures 1 to 3 comprises a cylindrical body 1 closed at one of its ends by a
Suivant l'invention le corps 1 et le bouton de commande 9 ont une section droite non circulaire mais qui présente un centre de symétrie sur l'axe longitudinal zz' du corps 1 et du bouton 9. Cette section droite a sensiblement la forme d'une ellipse dans la forme d'exécution représentée sur les figures 1 à 3. Si on considère la vue de dessus représentée. par la figure 3, on voit que le grand axe xx' de la section droite elliptique du bouton de commande 9 se trouve être perpendiculaire au grand axe yy' de la section droite elliptique du corps 1. Ceci correspond au milieu de la rotation élémentaire de 180° du bouton de commande 9 entre les deux positions dans lesquelles il se trouve. aligné avec le corps 1, autrement dit dans lesquelles les deux grands axes xx' et yy' sont confondus, c'est-à-dire que le bouton de commande à section droite elliptique 9 se trouve exactement dans le prolongement du. corps allongé à section droite elliptique 1.According to the invention the body 1 and the control button 9 have a non-circular cross section but which has a center of symmetry on the longitudinal axis zz 'of the body 1 and the button 9. This cross section has substantially the shape of an ellipse in the embodiment shown in Figures 1 to 3. If we consider the top view shown. by FIG. 3, we see that the major axis xx 'of the elliptical cross section of the control button 9 is found to be perpendicular to the major axis yy' of the elliptical cross section of the body 1. This corresponds to the middle of the elementary rotation of 180 ° of the control button 9 between the two positions in which it is located. aligned with the body 1, in other words in which the two major axes xx 'and yy' are merged, that is to say that the elliptical cross-section control button 9 is located exactly in line with the. elongated body with elliptical cross section 1.
La section droite elliptique du bouton de commande 9 peut être rigoureusement identique à celle du corps 1 ou légèrement plus grande ou plus petite tout en restant alors homothétique.The elliptical cross section of the control button 9 can be strictly identical to that of the body 1 or slightly larger or smaller while remaining homothetic.
On voit donc, d'après la description qui précède, que le passage du bouton de commande à section droite elliptique 9 d'une position dans laquelle il se trouve aligné avec le corps allongé 1 à une autre position similaire, se traduit par une rotation élémentaire d'un demi-tour. A cette rotation élémentaire correspond donc une translation du piston interne 5 d'une distance bien déterminée, autrement dit à la sortie d'une dose précise de produit pâteux 4.It is therefore seen, from the above description, that the passage of the elliptical cross-section control button 9 from a position in which it is aligned with the elongated body 1 to another similar position, results in a rotation elementary of a U-turn. This elementary rotation therefore corresponds to a translation of the
Les figures 4 et 5 illustrent une variante d'exécution du tube doseur suivant l'invention dans laquelle le corps 11 et le bouton de commande 12 ont chacun une section droite en forme de triangle équilatéral. Dans ce cas chaque rotation élémentaire du bouton de commande 12, par rapport au corps 11, entre une position dans laquelle il se trouve aligné avec le corps 11 et une position d'alignement suivante, correspond à un angle de 120°. Autrement dit la dose élémentaire sortant du tube doseur correspond à un déplacement élémentaire du piston interne 5 entraîné par un tiers de tour du bouton de commande 12.Figures 4 and 5 illustrate an alternative embodiment of the dosing tube according to the invention in which the
Dans la variante d'exécution illustrée sur les figures 6 et 7 le tube doseur comporte un corps 13 et un bouton de commande 14 peut être tourné par quart de tour, chaque quart de tour correspondant à une dose précise de produit pâteux sortant du tube doseur.In the variant illustrated in FIGS. 6 and 7, the dosing tube comprises a
