Description

La présente invention concerne un procédé et un système pour le conditionnement d'une paillette avec un liquide.The present invention relates to a method and system for packaging of a straw with a liquid.

Les paillettes, utilisées largement pour la conservation de petites quantités de substances, notamment de substances biologiques et en particulier de liquides biologiques, ont été divulguées pour la première fois dans le Brevet Français N° 995 878. De telles paillettes, appelées "paillettes françaises" comprenaient un bouchon tripartite constitué par deux tampons d'une substance fibreuse enserrant une poudre susceptible de se transformer au contact d'un liquide en une pâte ou gel imperméable adhérant à la paroi du tube en créant un bouchon étanche.Glitter, widely used for the preservation of small quantities of substances, in particular biological substances and in particular liquids have been disclosed for the first time in the French Patent N ° 995 878. Such flakes, called "French flakes" included a tripartite stopper consisting of two pads of a fibrous substance enclosing a powder capable of transforming on contact with a liquid into a paste or gel waterproof adhering to the wall of the tube creating a waterproof cap.

Les paillettes à bouchon tripartite mises au point et commercialisées par la Demanderesse donnent toute satisfaction. Néanmoins, une certaine absorption de liquide contenu dans la paillette a pu être constatée, quoique très faible. Aussi, la Demanderesse a-t-elle mis au point une paillette avec un bouchon monobloc microporeux hydrophobe, dénommé également "bouchon non absorbant". Une telle paillette est décrite dans la demande de brevet de la Demanderesse FR-A-2 762 210 du 21 avril 1997.The tripartite cap flakes developed and marketed by the Plaintiff give all satisfaction. However, some absorption of liquid contained in the glitter could be noted, although very weak. Also, the Has the Applicant developed a flake with a one-piece stopper hydrophobic microporous, also called "non-absorbent plug". Such a glitter is described in the patent application of the Applicant FR-A-2 762 210 of the April 21, 1997.

Les paillettes à bouchon tripartite sont remplies par remplissage horizontal par aspiration. Le liquide à conditionner est introduit dans la paillette horizontale à l'aide d'une pompe à aspiration. Le remplissage horizontal d'une paillette à bouchon tripartite est décrit notamment dans la demande de brevet de la Demanderesse EP-A-0 480 109.The tripartite plug flakes are filled by horizontal filling with aspiration. The liquid to be conditioned is introduced into the horizontal straw using a suction pump. Horizontal filling of a tripartite plug straw is described in particular in the patent application of the Applicant EP-A-0 480 109.

Ce système convient parfaitement pour des paillettes de petit diamètre mais non pour des paillettes ayant un diamètre important. Par "diamètre important", il faut entendre dans la présente invention un diamètre supérieur ou égal à environ 3 mm.This system is perfectly suited for small diameter flakes but not for glitter with a large diameter. "Large diameter" means hear in the present invention a diameter greater than or equal to about 3 mm.

Un objet de l'invention est de disposer d'un procédé permettant de conditionner un liquide à l'intérieur de paillettes ayant un diamètre important.An object of the invention is to have a method for conditioning a liquid inside the flakes having a large diameter.

D'autres objets et avantages de l'invention apparaítront à la lecture de la description ci-après.Other objects and advantages of the invention will appear on reading the description below.

La présente invention répond à l'objet ci-dessus et fournit un procédé de conditionnement d'une paillette ayant un diamètre supérieur ou égal à environ 3 mm avec un liquide, dans lequel on procède à un remplissage vertical de ladite paillette, caractérisé en ce que l'on sélectionne une paillette munie d'un bouchon perméable aux gaz et imperméable aux liquides, caractérisé en ce que l'on effectue un vide primaire dans la paillette, puis on remplit la paillette et on évacue la quantité d'air restante dans la partie située au-dessus de la colonne de liquide formée, permettant ainsi un remplissage homogéne de ladite paillette.The present invention fulfills the above object and provides a method of packaging of a straw with a diameter greater than or equal to approximately 3 mm with a liquid, in which a vertical filling of said straw is carried out, characterized in that a straw is provided with a plug permeable to gas and impermeable to liquids, characterized in that a primary vacuum is effected in the straw, then fill the straw and exhaust the remaining amount of air in the part located above the liquid column formed, thus allowing a homogeneous filling of said flake.

Le remplissage vertical simple, qui fait appel à une pompe volumétrique doseuse, est déjà connu, notamment dans les automates de laboratoire.Simple vertical filling, which uses a positive displacement pump dosing machine, is already known, in particular in laboratory automatons.

Cependant, un tel remplissage vertical avec mouvement asservi de l'aiguille présente, pour le remplissage d'une paillette munie d'un bouchon non absorbant, de nombreux inconvénients, liés à la largeur importante de la paillette relativement à son diamètre, notamment des problèmes de vitesse de remplissage et de précision de guidage de l'aiguille (l'aiguille risque de toucher la paroi de la paillette et de fait emprisonner des bulles d'air).However, such vertical filling with controlled movement of the needle has, for filling a straw with a non-absorbent cap, many disadvantages, related to the large width of the sequin relative to its diameter, in particular problems of filling speed and accuracy of needle guide (the needle may touch the wall of the glitter and in fact trap air bubbles).

Dans le remplissage vertical classique, la durée nécessitée de remplissage est longue, et il peut y avoir une présence de bulles d'air au cours de celui-ci.In conventional vertical filling, the required filling time is long, and there may be air bubbles present during it.

Au contraire, le procédé de remplissage vertical de la présente invention ne nécessite pas de mouvement asservi et offre une possibilité de rappel de goutte.On the contrary, the vertical filling process of the present invention does not requires no controlled movement and offers a possibility of gout recall.

Il faut noter que le procédé de l'invention peut être appliqué également à des paillettes n'ayant pas un diamètre important, c'est-à-dire, des paillette de diamètre inférieur à environ 3 mm.It should be noted that the method of the invention can also be applied to flakes not having a large diameter, that is to say, flakes of diameter less than about 3 mm.

En outre, dans le remplissage horizontal, l'effet de gravité, de viscosité et de tension de surface souille la partie inférieure de la paillette pendant le remplissage et le recul de la buse.In addition, in horizontal filling, the effect of gravity, viscosity and surface tension stains the bottom part of the flake during filling and nozzle recoil.

Par rapport au remplissage horizontal, le remplissage vertical de la présente invention apporte l'avantage de ne pas conduire à une souillure dans la zone de scellage, ce qui est un gage de sécurité pour la conservation du produit conditionné.Compared to horizontal filling, vertical filling of this invention provides the advantage of not leading to contamination in the area of sealing, which is a guarantee of security for the conservation of the packaged product.

Avec le remplissage vertical selon l'invention, l'émulsion des solutions moussantes est également limitée.With the vertical filling according to the invention, the emulsion of the solutions foaming is also limited.

En revanche, le procédé de l'invention ne convient pas pour des paillettes à bouchon tripartite.On the other hand, the process of the invention is not suitable for flakes with tripartite cap.

La présente invention propose également un système pour le remplissage d'une paillette munie d'un bouchon perméable aux gaz et imperméable aux liquides, mettant en oeuvre le procédé ci-dessus, caractérisé en ce qu'il comprend:

  • une pompe à dépression pour faire un vide primaire dans la paillette,
  • une pompe volumétrique pour remplir la paillette,
  • une buse de remplissage,
  • un socle comportant une aiguille de remplissage raccordée à ladite pompe volumétrique et un évent de mise à l'air libre pour évacuer la quantité d'air restante dans la partie située au-dessus de la colonne de liquide formée.
The present invention also provides a system for filling a straw provided with a gas permeable and liquid impermeable cap, implementing the above method, characterized in that it comprises:
  • a vacuum pump to create a primary vacuum in the straw,
  • a positive displacement pump to fill the straw,
  • a filling nozzle,
  • a base comprising a filling needle connected to said positive displacement pump and an air vent to evacuate the quantity of air remaining in the part situated above the column of liquid formed.

L'invention sera décrite plus en détail en référence aux Figures annexées, dans lesquelles:

  • les Figures 1 à 5 sont des vues schématiques d'une paillette au cours des différentes phases du procédé de conditionnement selon l'invention;
  • la Figure 6 est une vue schématique du système de remplissage selon l'invention.
The invention will be described in more detail with reference to the appended Figures, in which:
  • Figures 1 to 5 are schematic views of a straw during the different phases of the packaging process according to the invention;
  • Figure 6 is a schematic view of the filling system according to the invention.

Pour une meilleure compréhension de l'invention, sur les Figures 1 à 5 la paillette 1 a été représentée avec une aiguille de remplissage 7 et un évent 8 de mise à l'air libre, disposés sur un socle 9, ainsi qu'avec un raccordement 10 à une pompe à dépression.For a better understanding of the invention, in Figures 1 to 5 the straw 1 has been shown with a filling needle 7 and a vent 8 for setting open air, arranged on a base 9, as well as with a connection 10 to a pump depression.

Selon la présente invention, on sélectionne une paillette 1 de diamètre "d" supérieur ou égal à 3 mm, avec un bouchon 2 perméable aux gaz et imperméable aux liquides.According to the present invention, a straw 1 of diameter "d" is selected. greater than or equal to 3 mm, with a plug 2 permeable to gases and impermeable to liquids.

A l'extrémité de la paillette comportant le bouchon, on place un raccordement 10 à une pompe à dépression (non représentée). A l'extrémité de la paillette opposée au bouchon, on place une buse de remplissage 11 (voir Figure 6) avec une aiguille de remplissage 7 raccordée à une pompe volumétrique, c'est-à-dire une pompe doseuse (non représentée) avec rappel de goutte et un évent 8 de mise à l'air libre. L'aiguille de remplissage 7 et l'évent 8 sont placés sur un socle 9.At the end of the straw containing the plug, a connection 10 is placed to a vacuum pump (not shown). At the end of the glitter opposite the cap, place a filling nozzle 11 (see Figure 6) with a needle filling 7 connected to a positive displacement pump, i.e. a metering pump (not shown) with drop reminder and a vent 8 for venting. The needle filling 7 and the vent 8 are placed on a base 9.

Dans la Figure 2, on effectue un vide primaire dans la paillette.In Figure 2, a primary vacuum is made in the straw.

Dans la Figure 3, on commence à remplir la paillette avec du liquide 3. Une "partie de vide" 4 se trouve encore à proximité du bouchon.In Figure 3, we begin to fill the straw with liquid 3. A "vacuum part" 4 is still close to the plug.

Dans la Figure 4, on continue le remplissage de la paillette; il n'y a plus aucune "partie de vide" à proximité du bouchon; il reste un volume d'air 5 au-dessus de la colonne de liquide 6.In Figure 4, the filling of the straw is continued; there is no longer any "vacuum part" near the plug; there remains an air volume 5 above the liquid column 6.

Dans la Figure 5, le volume d'air restant 5 continue à être évacué.In Figure 5, the remaining air volume 5 continues to be exhausted.

La paillette remplie est ensuite scellée de façon connue en soi, par exemple comme indiqué dans EP-A-0 304 358 de la Demanderesse.The filled straw is then sealed in a manner known per se, for example as indicated in EP-A-0 304 358 from the Applicant.

Selon un exemple non limitatif de la présente invention, une paillette ayant un volume de 2 ml et un diamètre intérieur de 5,2 mm est remplie au moyen d'une aiguille de remplissage ayant un diamètre de 2 mm. La pompe de mise en dépression provoque une dépression d'environ 800 mm de Hg. Le débit est d'environ 10 l/mn.According to a nonlimiting example of the present invention, a straw having a volume of 2 ml and an internal diameter of 5.2 mm is filled using a needle filling with a diameter of 2 mm. The vacuum pump causes a vacuum of approximately 800 mm of Hg. The flow rate is approximately 10 l / min.

L'homme de l'art comprendra que bien que l'invention ait été décrite et illustrée pour des modes de réalisation particuliers, de nombreuses variantes peuvent être envisagées tout en restant dans le cadre de l'invention tel que défini dans les revendications annexées.Those skilled in the art will understand that although the invention has been described and illustrated for particular embodiments, many variants can be envisaged while remaining within the framework of the invention as defined in the appended claims.
