Description

La présente invention est relative à la fabrication des flacons distributeurs de produit, et elle concerne en premier lieu une bague porte-pompe pour un tel flacon, du type comprenant un manchon adapté pour recevoir une pompe de distribution et sur lequel peut être fixée une poche dont l'intérieur contient le produit à distribuer. L'invention s'applique notamment aux flacons dits "airless", c'est-à-dire remplis sous vide d'air et contenant un produit protégé de l'air.The present invention relates to the manufacture of product dispensing bottles, and it relates firstly to a pump-holder ring for such a bottle, of the type comprising a sleeve adapted to receive a dispensing pump and on which a pocket can be fixed. whose interior contains the product to be distributed. The invention applies in particular to so-called "airless" bottles, that is to say filled with air vacuum and containing a product protected from air.

Les flacons "airless" comportent généralement une poche souple dont l'ouverture est fixée de manière étanche autour d'un manchon porte-pompe, lequel est muni de moyens d'inviolabilité. L'ensemble peut être disposé dans un boîtier relativement rigide, pourvu de moyens de positionnement du manchon, pour permettre une utilisation commode. Une telle bague est décrite dans le document EP-A-0 486 355."Airless" bottles generally include a flexible pocket, the opening of which is tightly fixed around a pump-carrying sleeve, which is provided with tamper-evident means. The assembly can be arranged in a relatively rigid case, provided with means for positioning the sleeve, to allow convenient use. Such a ring is described in document EP-A-0 486 355.

Le remplissage de tels flacons pose de sérieuses difficultés du fait de la nécessité d'éviter tout contact du produit avec l'air. On a proposé pour cela des pompes distributrices spéciales à travers lesquelles peuvent s'effectuer la mise sous vide de la poche puis son remplissage, mais le coût de fabrication de telles pompes s'est révélé prohibitif.Filling such bottles poses serious difficulties due to the need to avoid any contact of the product with air. Special dispensing pumps have been proposed for this, through which the bag can be evacuated and then filled, but the manufacturing cost of such pumps has proved prohibitive.

L'invention a pour but de permettre l'utilisation économique de pompes classiques, éventuellement légèrement modifiées dans leurs dimensions, pour les flacons "airless".The invention aims to allow the economical use of conventional pumps, possibly slightly modified in their dimensions, for "airless" bottles.

A cet effet, l'invention a pour objet une bague porte-pompe du type précité, caractérisée en ce que l'extrémité interne du manchon est équipée d'un joint d'étanchéité élastique qui obture normalement cette extrémité et qui est adapté pour être ouvert par l'extrémité interne de la pompe lors de la mise de celle-ci en position de travail dans le manchon.To this end, the subject of the invention is a pump-holder ring of the aforementioned type, characterized in that the internal end of the sleeve is equipped with an elastic seal which normally closes this end and which is adapted to be opened by the internal end of the pump when putting it in working position in the sleeve.

Suivant d'autres caractéristiques :

  • le joint comporte un corps fixé, notamment par surmoulage, autour du manchon et prolongé par un bourrelet fendu en saillie au-delà de l'extrémité interne du manchon;
  • le manchon comporte une membrane d'inviolabilité percée d'un orifice central.
According to other characteristics:
  • the seal comprises a body fixed, in particular by overmolding, around the sleeve and extended by a split bead projecting beyond the internal end of the sleeve;
  • the sleeve has a tamper-evident membrane pierced with a central orifice.

L'invention a également pour objet un ensemble de distribution d'un produit comprenant une bague porte-pompe telle que définie ci-dessus, et une poche souple dont l'ouverture est fixée de manière étanche, notamment par soudage, autour du manchon.The invention also relates to a product distribution assembly comprising a pump-holder ring as defined above, and a flexible bag, the opening of which is tightly fixed, in particular by welding, around the sleeve.

Suivant d'autres caractéristiques, l'ensemble comprend en outre :

  • une pompe de distribution munie d'un prolongement inférieur adapté pour traverser le bourrelet du joint en position de travail de la pompe, et une capsule vissable sur le manchon et prenant appui sur la pompe, cette capsule étant destinée à amener la pompe en position de travail;
  • une bande d'inviolabilité amovible entourant le manchon au-dessous de la capsule lorsque celle-ci est en position d'attente;
  • un boîtier relativement rigide adapté pour recevoir la poche et muni de moyens de positionnement du manchon.
According to other characteristics, the set also includes:
  • a dispensing pump provided with a lower extension adapted to pass through the bead of the seal in the working position of the pump, and a capsule screwable on the sleeve and bearing on the pump, this capsule being intended to bring the pump into the job;
  • a removable tamper-evident band surrounding the sleeve below the capsule when the latter is in the standby position;
  • a relatively rigid housing adapted to receive the pocket and provided with means for positioning the sleeve.

L'invention a encore pour objet un procédé de remplissage d'un ensemble de distribution de produit tel que défini ci-dessus. Suivant ce procédé :

  • on introduit à travers un bourrelet du joint un embout d'aspiration, et on relie cet embout à une source de vide;
  • on introduit à travers le bourrelet du joint un embout de remplissage de produit, et on relie cet embout à une source de produit en surpression; et
  • on retire l'embout de remplissage.
The invention also relates to a method of filling a product distribution assembly as defined above. According to this process:
  • a suction nozzle is introduced through a bead of the joint, and this nozzle is connected to a source of vacuum;
  • a product filling nozzle is introduced through the bead of the joint, and it is connected this nozzle to a source of overpressure product; and
  • the filling nozzle is removed.

De façon avantageuse, on utilise un embout unique adapté pour être relié sélectivement à l'une ou l'autre des deux sources.Advantageously, use is made of a single nozzle adapted to be selectively connected to one or the other of the two sources.

Un exemple de réalisation de l'invention va maintenant être décrit en regard des dessins annexés, sur lesquels :

  • la Figure 1 représente en coupe longitudinale une bague porte-pompe conforme à l'invention;
  • les Figures 2 et 3 sont des vues analogues illustrant les deux phases du remplissage d'un ensemble de distribution de produit suivant l'invention, comprenant la bague porte-pompe de la Figure 1;
  • la Figure 4 est une vue analogue de l'ensemble de distribution complété par une pompe et une capsule; et
  • les Figures 5 et 6 sont des vues analogues représentant les deux phases de la mise en service de l'ensemble de distribution.
An embodiment of the invention will now be described with reference to the accompanying drawings, in which:
  • Figure 1 shows in longitudinal section a pump holder ring according to the invention;
  • Figures 2 and 3 are similar views illustrating the two phases of filling a product dispensing assembly according to the invention, comprising the pump holder ring of Figure 1;
  • Figure 4 is a similar view of the distribution assembly completed by a pump and a capsule; and
  • Figures 5 and 6 are similar views showing the two phases of the commissioning of the distribution assembly.

Pour la commodité de la description, on supposera que les éléments sont orientés comme représenté, avec leur axe de symétrie X-X vertical.For the convenience of the description, it will be assumed that the elements are oriented as shown, with their vertical axis of symmetry X-X.

La bague porte-pompe 1 représentée à la Figure 1 est constituée de deux pièces assemblées par surmoulage, à savoir d'un manchon 2 en matière plastique et d'un joint d'étanchéité 3 en élastomère.The pump carrier ring 1 shown in Figure 1 consists of two parts assembled by overmolding, namely a sleeve 2 of plastic and a seal 3 of elastomer.

Le manchon 2 est à double paroi. Sa paroi extérieure présente, de bas en haut : une base 4 de conformation appropriée servant à la fixation par soudage de l'ouverture d'une poche souple 5 visible aux Figures 2 à 6; une zone 6 à dents de rochet servant au positionnement d'une bague d'inviolabilité 7 visible sur la Figure 4; et une zone filetée 8.The sleeve 2 is double walled. Its outer wall has, from bottom to top: a base 4 of suitable conformation used for fixing by welding the opening of a flexible pocket 5 visible in Figures 2 to 6; a ratchet-toothed zone 6 used for positioning a tamper-evident ring 7 visible in FIG. 4; and a threaded area 8.

La paroi intérieure 9 du manchon est cylindrique et lisse. Son extrémité supérieure se raccorde à la paroi extérieure, à une petite distance de l'extrémité supérieure de celle-ci, par une collerette horizontale 10. L'extrémité inférieure de la paroi 9 est légèrement en retrait par rapport à celle de la base 4.The inner wall 9 of the sleeve is cylindrical and smooth. Its upper end is connected to the outer wall, a small distance from the upper end thereof, by a horizontal flange 10. The lower end of the wall 9 is slightly set back from that of the base 4 .

Un espace annulaire borgne 11, ouvert vers le bas, est défini entre les deux parois du manchon 2. Cet espace est entièrement empli par l'élastomère du joint 3, lequel se prolonge par le bas par un bourrelet 12. Ce dernier obture normalement l'ouverture inférieure de la paroi 9 et est fendu en 13 dans au moins un plan diamétral. Ainsi, en introduisant un embout de haut en bas à travers le manchon 2, on peut ouvrir temporairement le bourrelet 12.A blind annular space 11, open towards the bottom, is defined between the two walls of the sleeve 2. This space is entirely filled by the elastomer of the seal 3, which extends from below by a bead 12. The latter normally closes the 'lower opening of the wall 9 and is split at 13 in at least one diametrical plane. Thus, by introducing a nozzle from top to bottom through the sleeve 2, it is possible to temporarily open the bead 12.

Le remplissage de la poche 5 est illustré aux Figures 2 et 3.The filling of the bag 5 is illustrated in Figures 2 and 3.

On utilise un embout unique 14 comportant une tête supérieure 15 adaptée pour prendre appui sur la collerette 10, un corps cylindrique 16 à peu près de même longueur que la paroi 9 et reçu librement dans celle-ci, et un appendice inférieur 17 de diamètre réduit et convergent vers le bas. Lorsque la tête 15 se trouve contre la collerette 10, l'appendice 17 traverse le bourrelet 12 en ouvrant la fente 13.A single end piece 14 is used, comprising an upper head 15 adapted to bear on the flange 10, a cylindrical body 16 roughly the same length as the wall 9 and freely received therein, and a lower appendage 17 of reduced diameter. and converge downward. When the head 15 is against the flange 10, the appendage 17 passes through the bead 12 by opening the slot 13.

La tête 15 est reliée à deux conduites, l'une 18 elle-même reliée à une source de vide 19 et équipée d'une vanne 20, et l'autre 21 elle-même reliée à une source 22 du produit à distribuer et équipée d'une vanne 23.The head 15 is connected to two pipes, one 18 itself connected to a vacuum source 19 and equipped with a valve 20, and the other 21 itself connected to a source 22 of the product to be dispensed and equipped a valve 23.

Dans une première phase (Figure 2), la vanne 23 est fermée et la vanne 20 est ouverte. L'air contenu dans la poche 5 est donc évacué, et la poche s'aplatit sur elle-même.In a first phase (Figure 2), the valve 23 is closed and the valve 20 is open. The air contained in the pocket 5 is therefore evacuated, and the pocket flattens on itself.

Dans une seconde phase (Figure 3), les vannes sont inversées, et le produit remplit donc la poche, sous une légère surpression.In a second phase (Figure 3), the valves are reversed, and the product therefore fills the bag, under slight overpressure.

En fin de remplissage, la poche est totalement pleine de produit, sans air, et lorsqu'on retire l'embout 14, le bourrelet 12 se referme élastiquement, la surpression du produit contribuant à son étanchéité, comme illustré par des flèches sur la Figure 4.At the end of filling, the bag is completely full of product, without air, and when the end piece 14 is removed, the bead 12 closes elastically, the overpressure of the product contributing to its tightness, as illustrated by arrows in the Figure 4.

On complète ensuite l'ensemble (Figure 4) par une pompe de distribution 24 et une capsule 25 munie de la bande d'inviolabilité 7.The assembly is then completed (FIG. 4) by a distribution pump 24 and a capsule 25 provided with the tamper-evident band 7.

La pompe est d'un type classique, par exemple une pompe VB 36/200 de la société française VALOIS, dont le corps a simplement été prolongé vers le bas par un appendice tubulaire 26 de diamètre réduit et convergent vers le bas, analogue à l'appendice 17 de l'embout 14. Extérieurement, la pompe présente au-dessus de l'appendice 26 un corps cylindrique 27 pouvant coulisser à frottement dans la paroi 9 du manchon 2, et une tête supérieure élargie 28 d'où part vers le haut un tube central 29 de distribution.The pump is of a conventional type, for example a VB 36/200 pump from the French company VALOIS, the body of which has simply been extended downwards by a tubular appendage 26 of reduced diameter and converging downwards, similar to the 'appendage 17 of the end piece 14. Externally, the pump has above the appendage 26 a cylindrical body 27 which can slide in friction in the wall 9 of the sleeve 2, and an enlarged upper head 28 from which goes towards the up a central distribution tube 29.

La capsule 25 a une forme de coupelle renversée, avec un fond supérieur 30 traversé librement en son centre par le tube 29 et une jupe périphérique 31 filetée intérieurement. La tranche d'extrémité inférieure de cette jupe est reliée par des picots 32 à la tranche d'extrémité supérieure de la bande 7. Cette dernière comporte intérieurement des dents de rochet adaptées pour coopérer avec celles du manchon 2.The capsule 25 has an inverted cup shape, with an upper bottom 30 freely traversed in its center by the tube 29 and a peripheral skirt 31 internally threaded. The lower end edge of this skirt is connected by pins 32 to the upper end edge of the strip 7. The latter has internally ratchet teeth adapted to cooperate with those of the sleeve 2.

La pompe est insérée dans le manchon 2, presque jusqu'au contact du bourrelet 12, et l'ensemble 7-25 est vissé partiellement sur le manchon, jusqu'à ce que la bande 7 bute sur l'épaulement 6A qui limite inférieurement la zone dentée 6. Dans cette position, le fond 30 de la capsule 25 se trouve à une petite distance de la tête de pompe 28.The pump is inserted into the sleeve 2, almost until contact with the bead 12, and the assembly 7-25 is partially screwed onto the sleeve, until the strip 7 abuts on the shoulder 6A which lowerly limits the toothed zone 6. In this position, the bottom 30 of the capsule 25 is located a short distance from the pump head 28.

Pour l'utilisation, on retire la bande 7 (Figure 5), puis (Figure 6) on dispose l'ensemble restant dans un boîtier 33 relativement rigide muni de moyens de positionnement du manchon 2. Il peut s'agir par exemple d'un boîtier en matière plastique ayant un col supérieur 34, à collerette intérieure d'extrémité 35, de réception du manchon et un fond amovible, ou bien un boîtier en une seule pièce, articulé, tel que décrit dans la demande de brevet FR 92 03 111 de la Demanderesse et définissant le col 34 en position fermée.For use, remove the strip 7 (Figure 5), then (Figure 6) the remaining assembly is placed in a relatively rigid housing 33 provided with means for positioning the sleeve 2. It may for example be a plastic housing having an upper neck 34 , with inner end flange 35, for receiving the sleeve and a removable bottom, or else a single-piece housing, articulated, as described in patent application FR 92 03 111 of the Applicant and defining the neck 34 in closed position.

La partie filetée du manchon fait saillie hors de ce col sur une hauteur prédéterminée par la butée contre la collerette 35 d'un épaulement 6B du manchon délimitant vers le haut la zone dentée 6, et l'on visse la capsule 25 sur le manchon jusqu'à ce qu'elle bute sur la surface supérieure de la même collerette (Figure 6). Ce faisant, la capsule presse la pompe vers le bas et force son appendice 26 à traverser le bourrelet 12 en l'ouvrant, ce qui met la pompe en communication avec l'intérieur de la poche.The threaded part of the sleeve protrudes from this neck over a predetermined height by the stop against the flange 35 of a shoulder 6B of the sleeve delimiting upward the toothed zone 6, and the capsule 25 is screwed onto the sleeve until 'so that it abuts on the upper surface of the same flange (Figure 6). In doing so, the capsule presses the pump downwards and forces its appendage 26 to pass through the bead 12 by opening it, which puts the pump in communication with the interior of the pocket.

La pose du bouton-pression de distribution 37 sur le tube 29 complète le montage.The installation of the dispensing press button 37 on the tube 29 completes the assembly.

Si nécessaire, un joint d'étanchéité torique (non représenté) peut être interposé entre la tête de pompe 28 et la collerette 10.If necessary, an O-ring seal (not shown) can be interposed between the pump head 28 and the flange 10.
