Description

DISPOSITIF DE DOSAGE POUR PRODUITS LIQUIDES CONTENUS DANS DOSING DEVICE FOR LIQUID PRODUCTS CONTAINED IN
DES FLACONS OU SIMILAIRES.BOTTLES OR THE LIKE.
La présente invention concerne un dispositif de dosage destiné à être inséré dans le goulot d'un flacon ou récipient similaire contenant un liquide.The present invention relates to a metering device intended to be inserted into the neck of a bottle or similar container containing a liquid.
On connaît déjà des dispositifs de dosage de liquide, engagés dans le goulot d'un flacon, comportant deux compartiments, à savoir un premier compartiment doseur se remplissant d'un volume de liquide prédéterminé lors du retournement du flacon à partir de sa position verticale normale et un second compartiment de réserve communiquant avec le compartiment doseur de manière à recevoir le volume de liquide prédéterminé contenu dans le compartiment doseur lors de la remise en place du flacon en position verticale normale. Le compartiment de réserve communique par ailleurs avec un orifice de sortie du dispositif de dosage de manière à déverser à l'extérieur la dose de liquide contenu dans le compartiment de réserve, lors du retournement du flacon. Un tel dispositif est décrit par exemple dans le brevet FR-1.047.119. Ce brevet décrit un bouchon doseur constitué par une armature tubulaire avec une partie supérieure profilée formant bouchon externe et une partie inférieure obturée par un bouchon coulissant ; un cloisonnement interne divise l'armature en deux chambres, une chambre de remplissage et une chambre de réserve. L'armature comporte un orifice de remplissage et un orifice d'échappement d'air pratiqué dans les parois de la chambre de remplissage. En renversant la bouteille, le liquide peut alors pénétrer dans l'orifice de remplissage dans la chambre correspondante jusqu'à la hauteur de l'orifice d'échappement d'air qui est le point d'équilibre des pressions ; à ce moment là, si l'on redresse la bouteille, le liquide se déverse dans la chambre de réserve et le volume de liquide contenu dans la chambre de remplissage étant supérieur à celui de la chambre de réserve, le surplus s'évacue par l'orifice d'échappement d'air assurant le dosage. L'opérateur, en inclinant la bouteille, vide alors le contenu du doseur ce qui réamorce un nouveau dosage et le liquide excédentaire qui était demeuré dans la chambre de remplissage se mélange à nouveau avec le nouvel apport. On voit facilement qu'avec ce dispositif, l'évacuation du liquide excédentaire qui est assuré par l'orifice d'échappement d'air, définit en fait le niveau de remplissage de chaque chambre ; ainsi, les limites de remplissage sont identiques lorsque l'on commence à renverser le récipient pour vider la chambre de dosage, de sorte qu'une partie du liquide peut alors déborder de la chambre de réserve vers la chambre de remplissage créant incontestablement une imprécision du dosage puisque la quantité de liquide pouvant déborder de cette même chambre de remplissage varie selon que l'on incline le récipient dans un plan plus ou moins proche du plan de symétrie du bouchon .Liquid metering devices are already known, engaged in the neck of a bottle, comprising two compartments, namely a first metering compartment filling with a predetermined volume of liquid during the inversion of the bottle from its normal vertical position. and a second reserve compartment communicating with the dosing compartment so as to receive the predetermined volume of liquid contained in the dosing compartment when the bottle is replaced in the normal vertical position. The reserve compartment also communicates with an outlet orifice of the metering device so as to pour out the dose of liquid contained in the reserve compartment when the bottle is turned over. Such a device is described for example in patent FR-1,047,119. This patent describes a dosing cap constituted by a tubular frame with a profiled upper part forming an external cap and a lower part closed by a sliding cap; an internal partition divides the reinforcement into two chambers, a filling chamber and a reserve chamber. The frame has a filling orifice and an air exhaust orifice made in the walls of the filling chamber. By inverting the bottle, the liquid can then enter the filling orifice in the corresponding chamber up to the height of the air exhaust orifice which is the point of pressure equilibrium; at this time, if the bottle is straightened, the liquid pours into the reserve chamber and the volume of liquid contained in the filling chamber being greater than that of the reserve chamber, the surplus is evacuated by the air exhaust port for metering. The operator, by tilting the bottle, empties the contents of the dispenser which restarts a new dosage and the excess liquid which had remained in the filling chamber mixes again with the new supply. It is easy to see that with this device, the evacuation of the excess liquid which is ensured by the air exhaust orifice, in fact defines the level of filling of each chamber; thus, the filling limits are identical when one begins to invert the container to empty the dosing chamber, so that part of the liquid can then overflow from the reserve chamber towards the filling chamber undoubtedly creating an inaccuracy of the dosage since the amount of liquid that can overflow from this same filling chamber varies depending on whether the container is tilted in a plane more or less close to the plane of symmetry of the stopper.
La présente invention concerne un perfectionnement apporté au dispositif antérieur, dans le but d'améliorer la précision du dosage de liquide.The present invention relates to an improvement made to the prior device, with the aim of improving the precision of the liquid metering.
A cet effet, ce dispositif de dosage destiné à être inséré dans le goulot d'un flacon ou récipient similaire contenant un liquide comprenant deux compartiments, à savoir un premier compartiment doseur se remplissant d'un volume de liquide prédéterminé lors du retournement du flacon à partir de sa position verticale normale, et un second compartiment de réserve communiquant avec le compartiment doseur communiquant avec l'orifice de sortie du dispositif de dosage et avec le compartiment doseur de manière à recevoir le volume de liquide contenu dans ce dernier, lors de la remise du flacon en position normale comportant un élément tubulaire externe emboîté dans le goulot du flacon, fermé à son extrémité inférieure et ouvert à son extrémité supérieure, présentant, dans sa paroi latérale, une ouverture de remplissage proche de son extrémité supérieure et débouchant dans le compartiment doseur, un premier orifice d'évacuation de l'air (14), délimitant le niveau de remplissage du compartiment étant prévu dans la paroi de l'élément tubulaire extrême (4) et un élément tubulaire interne (5) emboîté d'une manière étanche dans l'élément tubulaire externe (4), comportant une partie extrême supérieure formant un bec verseur (17) , un corps intermédiaire (16) délimitant, vers l'intérieur, le compartiment doseur (A) et une partie extrême inférieure formant un conduit de transfert (23) s ' étendant vers le bas débouchant, à son extrémité supérieure, dans le compartiment doseur (A) et, à son extrémité inférieure, dans le compartiment de réserve (B) est, selon la caractéristique principale de l'invention, remarquable en ce que ledit élément tubulaire externe (4) comporte un second orifice de trop plein (15) situé à un niveau inférieur à celui de l'orifice d'évacuation de l'air (14), c'est-à-dire plus proche du fond de l'élément tubulaire externe (4) , et délimitant le niveau maximal de remplissage du compartiment de réserve (B) .To this end, this metering device intended to be inserted into the neck of a bottle or similar container containing a liquid comprising two compartments, namely a first metering compartment which is filled with a predetermined volume of liquid when the bottle is turned over. from its normal vertical position, and a second reserve compartment communicating with the dosing compartment communicating with the outlet orifice of the metering device and with the dosing compartment so as to receive the volume of liquid contained in the latter, during the return of the bottle to the normal position comprising an external tubular element fitted into the neck of the bottle, closed at its lower end and open at its upper end, having, in its side wall, a filling opening close to its upper end and opening into the metering compartment, a first air outlet orifice (14), defining the level filling water of the compartment being provided in the wall of the extreme tubular element (4) and an internal tubular element (5) fitted in a way sealed in the external tubular element (4), comprising an upper end part forming a pouring spout (17), an intermediate body (16) delimiting, inwards, the metering compartment (A) and a lower end part forming a transfer duct (23) extending downwards opening, at its upper end, into the metering compartment (A) and, at its lower end, in the reserve compartment (B) is, according to the main characteristic of the invention, remarkable in that said external tubular element (4) comprises a second overflow orifice (15) situated at a level lower than that of the air evacuation orifice (14), that is to say - say closer to the bottom of the external tubular element (4), and delimiting the maximum level of filling of the reserve compartment (B).
On comprend bien que l'orifice de dosage, c'est-à- dire l'orifice de trop plein, définit précisément le niveau maximal de remplissage du compartiment doseur ; en effet, ainsi, les deux compartiments étant séparés et, dans la mesure où, le compartiment de dosage n'est que partiellement rempli, le liquide ne peut pas déborder vers la chambre de remplissage c'est-à-dire vers le compartiment de réserve, lors du renversement du récipient ; il n'y a donc aucun retour du liquide vers le premier compartiment, que l'on incline le récipient dans le plan de symétrie du bouchon ou non, ce qui procure la précision de dosage souhaitée.It will be understood that the metering orifice, that is to say the overflow orifice, precisely defines the maximum level of filling of the metering compartment; indeed, thus, the two compartments being separated and, insofar as the metering compartment is only partially filled, the liquid cannot overflow towards the filling chamber, that is to say towards the reserve, when the container is overturned; there is therefore no return of the liquid to the first compartment, whether the container is tilted in the plane of symmetry of the cap or not, which provides the desired dosing precision.

Suivant l'invention, le dispositif de dosage 1 est constitué de deux éléments tubulaires emboîtés axialement l'un dans l'autre, à savoir un élément tubulaire externe 4 et un élément tubulaire interne 5.

Par ailleurs, le corps cylindrique 6 présente dans sa paroi à proximité de l'orifice supérieur, une ouverture 13 destinée à constituer l'orifice de remplissage du compartiment doseur A. Le corps cylindrique 6 présente également, dans une partie intermédiaire de sa paroi, un orifice d'évacuation de l'air 14 et, un peu en dessous de celui-ci, un autre orifice 15, comme on peut le voir sur la figure 1. Le rôle de ces orifices sera précisé dans la suite de la description.The external tubular element 4, shown in more detail in Figures 2 and 3, comprises a cylindrical body 6 closed at its lower end by a bottom 7 and open at its upper end. The external diameter of the cylindrical body 6 is substantially equal to the internal diameter of the neck 2a of the bottle 2. The cylindrical body 6 is integral, in its upper part, with a coaxial skirt 8 intended to cover, on the outside, the neck 2a of the bottle 2 which is fixed to the neck of the bottle by screwing with non-return, in a manner known per se. The skirt 8 carries a shutter 9 pivoting around a lateral hinge 11 ensuring its connection with the skirt 8 so as to be able to close the upper orifice of the cylindrical body 6. The shutter 9 may advantageously include a projecting part forming a plug 12 (Figure 1) to ensure a tight closure of the upper end of the internal tubular element 5 as will be explained below. Furthermore, the cylindrical body 6 has in its wall near the upper orifice, an opening 13 intended to constitute the filling orifice of the metering compartment A. The cylindrical body 6 also has, in an intermediate part of its wall, an air discharge orifice 14 and, a little below it, another orifice 15, as can be seen in FIG. 1. The role of these orifices will be specified in the following description.
On décrira maintenant, en se référant aux figures 4 à 13 , la structure de l'élément tubulaire interne 5. Cet élément 5 comporte un corps tubulaire intermédiaire 16, à section transversale courbe allant en diminuant de bas en haut et dont l'extrémité supérieure est prolongée par une partie cylindrique 17 formant bec verseur. Ce bec verseur 17 a un orifice incliné par rapport à l'axe longitudinal et il présente une fente longitudinale 18. Une jupe transversale cylindrique 19 est prévue dans la zone de jonction du corps intermédiaire 16 et du bec verseur cylindrique 17. Cette jupe transversale 19 a une paroi latérale cylindrique ayant un diamètre externe sensiblement égal au diamètre interne de la partie extrême supérieure de l'élément tubulaire externe 4 de manière à pouvoir s'y emboîter étroitement, d'une manière étanche, comme il est représenté sur la figure 1.We will now describe, with reference to Figures 4 at 13, the structure of the internal tubular element 5. This element 5 comprises an intermediate tubular body 16, with curved cross section decreasing from bottom to top and the upper end of which is extended by a cylindrical part 17 forming a spout . This pouring spout 17 has an opening inclined relative to the longitudinal axis and it has a longitudinal slot 18. A cylindrical transverse skirt 19 is provided in the junction zone of the intermediate body 16 and the cylindrical pouring spout 17. This transverse skirt 19 has a cylindrical side wall having an external diameter substantially equal to the internal diameter of the upper end part of the external tubular element 4 so as to be able to fit there tightly, in a sealed manner, as shown in FIG. 1 .
En dessous de la jupe 19, le corps tubulaire intermédiaire 16 porte un élément formant déviateur de flux 21 à section transversale en forme de T, comme il est représenté sur la figure 10, élément dont l'âme verticale 21a est rattachée au corps tubulaire intermédiaire 16. L'élément déviateur de flux 21 comprend par ailleurs une plaque plane verticale 21b, correspondant à la tête de la section transversale en forme de T, dont l'extrémité inférieure est reliée à une bride horizontale 21c, s ' étendant vers l'extérieur, en forme de segment de cercle dont le rayon de courbure est égal au rayon de la surface interne de 1 ' élément tubulaire externe 4, de manière à s'appliquer étroitement contre la paroi de cet élément lorsque les deux éléments tubulaires 4 et 5 sont emboîtés l'un dans l'autre.Below the skirt 19, the intermediate tubular body 16 carries an element forming a flow deflector 21 with a T-shaped cross section, as shown in FIG. 10, an element whose vertical core 21a is attached to the intermediate tubular body 16. The flow diverting element 21 also comprises a vertical flat plate 21b, corresponding to the head of the T-shaped cross section, the lower end of which is connected to a horizontal flange 21c, extending towards the outside, in the form of a segment of a circle, the radius of curvature of which is equal to the radius of the internal surface of the external tubular element 4, so as to apply closely against the wall of this element when the two tubular elements 4 and 5 are nested one inside the other.
A son extrémité inférieure, le corps tubulaire intermédiaire 16 est prolongé par une jupe cylindrique 22 dont le diamètre externe est sensiblement égal au diamètre interne de l'élément tubulaire externe 4, pour assurer l'étanchéité entre eux. Cette jupe 22 comporte une paroi latérale cylindrique s ' étendant vers le bas et une paroi supérieure 22a.At its lower end, the intermediate tubular body 16 is extended by a cylindrical skirt 22, the external diameter of which is substantially equal to the internal diameter of the external tubular element 4, in order to seal them. This skirt 22 has a cylindrical side wall extending downward and an upper wall 22a.
Par ailleurs, le corps tubulaire intermédiaire 16 est prolongé vers le bas par un conduit de transfert vertical 23, ouvert à ses deux extrémités, qui s'étend vers le bas jusqu'à proximité du fond de l'élément tubulaire externe 4. Ce conduit de transfert 23 est aligné verticalement avec l'élément déviateur de flux 21. Son orifice supérieur est situé au niveau de l'extrémité inférieure de la paroi supérieure 22a de la jupe 22 qui est avantageusement inclinée en direction de l'orifice supérieur du conduit de transfert 23. La section transversale du conduit de transfert 23 a, par exemple, une forme de "haricot" et sa surface externe est cylindrique avec un rayon de courbure égal à celui de la surface interne de 1 ' élément tubulaire externe 4.Furthermore, the intermediate tubular body 16 is extended downwards by a vertical transfer duct 23, open at its two ends, which extends downwards near the bottom of the external tubular element 4. This transfer duct 23 is aligned vertically with the flow deflecting element 21. Its upper orifice is located at the lower end of the upper wall 22a of the skirt 22 which is advantageously inclined towards the upper orifice of the transfer duct 23. The cross section of the duct transfer 23 has, for example, a "bean" shape and its external surface is cylindrical with a radius of curvature equal to that of the internal surface of the external tubular element 4.
Le dispositif de dosage 1 suivant 1 ' invention, constitué des deux éléments tubulaires 4,5 emboîtés l'un dans l'autre, se présente ainsi qu'il est représenté sur la figure 1. Dans cette position emboîtée, la jupe supérieure 19 de l'élément tubulaire interne 5 est emboîtée étroitement, d'une manière étanche, dans la partie extrême supérieure de l'élément tubulaire externe 4. L'élément déviateur de flux 21 s'étend en regard de l'ouverture 13, à partir de l'extrémité inférieure de celle-ci et de préférence son extrémité supérieure est située juste un peu au-delà de l'extrémité supérieure de l'ouverture 13. La bride inférieure 21ç_, en forme de segment de cercle, de l'élément déviateur de flux 21 est en contact étanche, suivant un arc de cercle, avec la paroi du corps cylindrique 6, juste en dessous de l'extrémité inférieure de l'ouverture 13, et la partie plane verticale 21b de l'élément déviateur 21 est en contact, le long de ses deux bords verticaux, avec la surface interne de l'élément tubulaire externe 4. Le corps cylindrique 6 délimite, vers l'intérieur, le compartiment doseur A qui est également délimité, vers l'extérieur par la paroi cylindrique de l'élément tubulaire externe 4. L'orifice d'évacuation de l'air 14 du corps cylindrique 6 est situé juste au-dessus de l'orifice supérieur du conduit de transfert 23 et l'orifice d'évacuation du trop plein 15, est situé juste en dessous du bord horizontal inférieur de la jupe 22 dont la paroi latérale cylindrique est appliquée d'une manière étanche contre la surface interne de l'élément tubulaire externe 4. Selon une configuration particulièrement avantageuse, le premier orifice d'évacuation de l'air 14 du corps cylindrique 6 est diamétralement opposé au bec verseur 17 et le second orifice d'évacuation du trop plein 15 est globalement à 90° par rapport au premier orifice 14 afin que l'écoulement de la dose initialement contenue dans le compartiment de réserve B s'effectue sans pertes.The metering device 1 according to the invention, consisting of two tubular elements 4,5 fitted one inside the other, is presented as shown in FIG. 1. In this fitted position, the upper skirt 19 of the internal tubular element 5 is tightly fitted in a sealed manner in the upper end part of the external tubular element 4. The flow diverting element 21 extends opposite the opening 13, starting from the lower end of the latter and preferably its upper end is located just a little beyond the upper end of the opening 13. The lower flange 21ç_, in the form of a segment of a circle, of the deflecting element flow 21 is in sealed contact, in an arc, with the wall of the cylindrical body 6, just below the lower end of the opening 13, and the vertical flat part 21b of the deflecting element 21 is in contact, along its two vertical edges, with the internal surface of the external tubular element 4. The cylindrical body 6 delimits, towards the inside, the metering compartment A which is also delimited, towards the outside by the cylindrical wall of the external tubular element 4 The air evacuation orifice 14 of the cylindrical body 6 is situated just above the upper orifice of the transfer duct 23 and the overflow evacuation orifice 15 is situated just in below the lower horizontal edge of the skirt 22, the cylindrical side wall of which is applied in a sealed manner against the internal surface of the external tubular element 4. According to a particularly advantageous configuration, the first air evacuation orifice 14 of the cylindrical body 6 is diametrically opposite the spout 17 and the second overflow discharge orifice 15 is generally 90 ° relative to the first orifice 14 so that the flow of the dose initially contained in the reserve compartment B s 'performs without losses.
Enfin, la surface externe courbe du conduit de transfert 23 est appliquée étroitement contre la surface interne du corps cylindrique 6 et son orifice inférieur situé à une faible distance du fond de l'élément tubulaire externe 4.Finally, the curved external surface of the transfer duct 23 is applied tightly against the internal surface of the cylindrical body 6 and its lower orifice located a short distance from the bottom of the external tubular element 4.
Le compartiment doseur A, qui se trouve en position supérieure lorsque le flacon est dans sa position normale, est délimité entre la jupe supérieure 19 de l'élément tubulaire interne 5 et l'orifice d'évacuation de l'air 14. Le compartiment de réserve B est, quant à lui, délimité entre le fond de 1 ' élément tubulaire externe 4 et l'orifice de trop plein 15.The dosing compartment A, which is in the upper position when the bottle is in its normal position, is delimited between the upper skirt 19 of the internal tubular element 5 and the air discharge orifice 14. The compartment reserve B is, for its part, delimited between the bottom of the external tubular element 4 and the overflow orifice 15.
On expliquera maintenant, le fonctionnement du dispositif de dosage 1 suivant 1 ' invention en se référant aux figures 1, 14 et 15.The operation of the metering device 1 according to the invention will now be explained with reference to FIGS. 1, 14 and 15.
Sur la figure 1, le flacon 2 est représenté avant sa première utilisation et dans ce cas, le liquide 3 se trouve en totalité à l'extérieur du dispositif de dosage 1. Lors de la première utilisation, on retourne le flacon 2 de 180°, pour l'amener dans la position représentée sur la figure 15 et le liquide 3 contenu dans le flacon s'écoule alors vers 1 ' intérieur du compartiment doseur A en passant à travers l'ouverture constituant l'orifice de remplissage 13, en étant dévié vers le bas, c'est-à-dire vers la jupe supérieure 19 par l'élément déviateur de flux 21, et en contournant ce dernier comme il est indiqué par les flèches. L'air contenu dans la partie supérieure du compartiment A, s'échappe à l'extérieur, à travers l'orifice d'évacuation 14. Le remplissage a lieu jusqu'à ce que le niveau du liquide dans le compartiment doseur A arrive sensiblement au niveau de l'orifice d'évacuation de l'air 14. Pendant cette première utilisation, aucun liquide ne sort du dispositif de dosage puisque le compartiment de réserve B se trouve alors vide.In FIG. 1, the bottle 2 is shown before its first use and in this case, the liquid 3 is entirely outside the metering device 1. During the first use, the bottle 2 is turned over by 180 ° , to bring it into the position shown in FIG. 15 and the liquid 3 contained in the bottle then flows towards the interior of the metering compartment A, passing through the opening constituting the filling orifice 13, being deflected down, that is to say towards the upper skirt 19 by the flow diverting element 21, and bypassing the latter as indicated by the arrows. The air in the upper part of the compartment A, escapes to the outside, through the evacuation orifice 14. The filling takes place until the level of the liquid in the metering compartment A comes substantially to the level of the evacuation orifice air 14. During this first use, no liquid leaves the metering device since the reserve compartment B is then empty.
Après remplissage du compartiment doseur A, on retourne le flacon pour le placer dans sa position normale telle que représentée sur la figure 14. Par suite de cette remise en position normale, la dose de liquide contenue dans le compartiment doseur A s'écoule rapidement dans le compartiment de réserve B, en passant à travers le conduit de transfert 23. La dose de liquide prédéterminée qui a été préalablement stockée dans le compartiment doseur A, est ainsi transférée intégralement au compartiment de réserve B, c'est-à-dire pratiquement jusqu'au niveau de l'orifice de trop plein 15. Le dispositif se trouve alors prêt à une première utilisation effective. Cette première utilisation s'effectue par retournement du flacon, comme représenté sur la figure 15, et par suite de ce retournement la dose de liquide contenue dans le compartiment de réserve B s'écoule à l'extérieur, à travers l'élément tubulaire interne 5 et le bec verseur 17. Pendant ce temps, le compartiment doseur A se remplit de nouveau de la dose de liquide prédéterminée qui sera ensuite transférée au compartiment de réserve B lorsque le flacon 2 aura été rétabli dans sa position normale.After filling the dosing compartment A, the bottle is turned over to place it in its normal position as shown in FIG. 14. Following this resetting to the normal position, the dose of liquid contained in the dosing compartment A flows quickly into the reserve compartment B, passing through the transfer duct 23. The predetermined dose of liquid which has been previously stored in the metering compartment A is thus transferred entirely to the reserve compartment B, that is to say practically up to the level of the overflow hole 15. The device is then ready for a first effective use. This first use is carried out by inverting the bottle, as shown in FIG. 15, and as a result of this inversion the dose of liquid contained in the reserve compartment B flows outside, through the internal tubular element. 5 and the pouring spout 17. During this time, the metering compartment A is again filled with the predetermined dose of liquid which will then be transferred to the reserve compartment B when the bottle 2 has been restored to its normal position.
Il est important de noter que le retournement du flacon 2 pour l'amener depuis sa position verticale normale, représentée sur la figure 14, jusqu'à sa position où le compartiment doseur A en cours de remplissage et le compartiment de réserve B en cours de vidage, représentée sur la figure 15, est avantageusement obtenu par une rotation d'environ 180° dans le sens inverse des aiguilles d'une montre pour que le remplissage du compartiment doseur A mais surtout que le vidage du compartiment de réserve B s'effectuent correctement assurant ainsi une meilleure précision du dosage. It is important to note that the inversion of the bottle 2 to bring it from its normal vertical position, shown in FIG. 14, to its position where the metering compartment A is being filled and the reserve compartment B is being emptying, shown in FIG. 15, is advantageously obtained by a rotation of approximately 180 ° anticlockwise so that the filling of the metering compartment A but above all that the emptying of the reserve compartment B is carried out correctly thus ensuring a better dosing accuracy.
