Description

La présente invention concerne un ensemble de distribution d'un produit dans lequel le produit à distribuer est contenu dans une poche souple.The present invention relates to a product distribution assembly in which the product to be distributed is contained in a flexible bag.

De tels ensembles sont utilisés plus particulièrement dans le cas où la tête de distribution, associée à la poche souple, constitue une pompe sans reprise d'air ou dans le cas de distributeurs de type aérosol dans lesquels le produit est introduit dans une poche souple et le gaz propulseur est introduit dans le bidon autour de la poche.Such assemblies are used more particularly in the case where the dispensing head, associated with the flexible bag, constitutes a pump without air intake or in the case of aerosol dispensers in which the product is introduced into a flexible bag and the propellant is introduced into the container around the pocket.

Les poches souples sont le plus souvent formées d'un sac comportant deux parois de forme variable, par exemple rectangulaire, les parois étant soudées sur au moins un côté. La poche souple est fixée de façon étanche, le plus souvent par soudure, sur une tête de distribution. Lors de la distribution du produit, la poche souple se vide peu à peu et, par conséquent, ses parois se rapprochent l'une de l'autre. Il est alors fréquent que les deux parois se touchent avant que la totalité du produit ne soit distribuée et se scellent l'une à l'autre sur une ou plusieurs zones, lesdites zones pouvant constituer une barrière étanche. Une partie du produit à distribuer peut se trouver ainsi piégée, sa distribution étant devenue impossible. Les pertes dues au produit ainsi piégé peuvent être très importantes. On a proposé dans le brevet US-A-4 381 846 d'introduire dans la poche souple, une grille qui au cours de l'écoulement du produit passe d'une première position où elle se déplace librement à une seconde position où elle recouvre l'ouverture de sortie du liquide à distribuer, et empêche l'aspiration des parois de la poche par l'ouverture de sortie. Le liquide peut alors traverser librement la grille et s'écouler par l'ouverture de sortie ; on évite ainsi que l'ouverture de sortie soit bouchée par aspiration des parois de la poche. Ce dispositif ne permet pas d'éviter que les parois latérales de la poche souple collent l'une à l'autre. Par conséquent, une partie du produit peut encore rester piégée.The flexible pockets are most often formed of a bag comprising two walls of variable shape, for example rectangular, the walls being welded on at least one side. The flexible bag is fixed in a sealed manner, most often by welding, on a dispensing head. During the distribution of the product, the flexible bag gradually empties and, therefore, its walls approach each other. It is then common for the two walls to touch before all of the product is distributed and to seal one another over one or more zones, said zones possibly constituting a tight barrier. Part of the product to be distributed may thus be trapped, its distribution having become impossible. The losses due to the product thus trapped can be very significant. It has been proposed in patent US-A-4 381 846 to introduce into the flexible bag, a grid which during the flow of the product passes from a first position where it moves freely to a second position where it covers the outlet opening of the liquid to be dispensed, and prevents the suction of the walls of the bag through the outlet opening. The liquid can then pass freely through the grid and flow through the outlet opening; this prevents the outlet opening from being blocked by suction from the walls of the pocket. This device does not prevent the side walls of the flexible bag from sticking to each other. As a result, part of the product may still remain trapped.

Pour éviter cet inconvénient, on introduit dans la poche souple selon la présente invention, une grille parallèle à l'axe de sortie du liquide et qui reste parallèle à cet axe.To avoid this drawback, there is introduced into the flexible bag according to the present invention, a grid parallel to the axis of exit of the liquid and which remains parallel to this axis.

La présente invention a donc pour objet un ensemble de distribution d'un produit dans lequel le produit à distribuer est contenu dans une poche souple fixée sur une tête de distribution et comportant une tubulure pour la sortie du produit de la poche, la poche souple contenant une pièce interne, caractérisé par le fait que la pièce interne est une pièce semi-rigide dont le plan moyen est pratiquement parallèle à l'axe de sortie du produit distribué, que les dimensions relatives de la poche et de la pièce sont telles que ladite pièce reste dans sa positionet ne puisse pas se mettre dans une position où son plan moyen serait perpendiculaire à l'axe de sortie du produit distribué, et que la pièce définit des canaux d'écoulement du produit distribué, vers la tubulure de sortie du produit.The present invention therefore relates to a product dispensing assembly in which the product to be dispensed is contained in a flexible bag fixed on a dispensing head and comprising a tube for removing the product from the bag, the flexible bag containing an internal part, characterized in that the internal part is a semi-rigid part, the mean plane of which is practically parallel to the outlet axis of the dispensed product, and that the relative dimensions of the bag and the part are such that said part remains in its position and cannot be placed in a position where its mean plane is perpendicular to the outlet axis of the dispensed product, and the part defines flow channels of the dispensed product, towards the outlet pipe of the product .

La pièce ainsi disposée permet de maintenir écartées les parois de la poche souple, de façon à les empêcher de se coller l'une à l'autre et de former une barrière étanche empêchant l'écoulement d'une partie du produit à distribuer vers la tubulure de sortie du produit.The piece thus arranged makes it possible to keep the walls of the flexible pouch apart, so as to prevent them from sticking to one another and to form a tight barrier preventing the flow of a part of the product to be distributed towards the product outlet tubing.

Selon l'invention, la pièce est semi-rigide de façon à ce qu'elle ne puisse pas se tordre, ou se plier, par exemple se mettre en spirale. En effet, l'écoulement du produit à distribuer serait perturbé.According to the invention, the part is semi-rigid so that it cannot twist, or bend, for example to spiral. Indeed, the flow of the product to be distributed would be disturbed.

La pièce semi-rigide peut couvrir une surface plus ou moins grande du plan médian de la poche souple, dans la mesure où ses dimensions ne lui permettent pas de se mettre dans une position perpendiculaire à l'axe de sortie du produit distribué.The semi-rigid part can cover a more or less large surface of the median plane of the flexible bag, insofar as its dimensions do not allow it to be placed in a position perpendicular to the axis of exit of the dispensed product.

De préférence la pièce semi-rigide ne couvre qu'une partie de ce plan médian. Cette disposition facilite l'introduction de la pièce dans ladite poche souple. De plus, lorsque la pièce est libre, elle peut se déplacer légèrement dans la poche souple, ce qui permet de mélanger le produit, éventuellement de briser sa thixotropie et d'éviter la formation de canaux préférentiels. En particulier la pièce est, de préférence, plus courte que la poche. Ainsi la poche peut se raccourcir et venir se plaquer sous la tête de distribution, ce qui permet de vider complètement la poche.Preferably the semi-rigid part covers only part of this median plane. This arrangement facilitates the introduction of the part into said flexible pocket. In addition, when the part is free, it can move slightly in the flexible pouch, which makes it possible to mix the product, possibly to break its thixotropy and to avoid the formation of preferential channels. In particular, the part is preferably shorter than the pocket. Thus the bag can be shortened and come to be pressed under the dispensing head, which allows the bag to be completely emptied.

La pièce peut être libre dans la poche souple. Elle est, de préférence, fixée à la tubulure de sortie du produit. On obtient ainsi toujours une jonction entre la pièce et l'orifice de sortie du produit et on empêche ainsi tout risque de formation entre la pièce et l'orifice de sortie, d'une barrière étanche par collage des parois de la poche. Le dispositif de fixation de la pièce est, de préférence, mobile en flexion et/ou en rotation par rapport à la tubulure de sortie du produit. Ainsi la pièce peut mieux résister aux déformations de la poche.The part can be free in the flexible pocket. It is preferably fixed to the product outlet tubing. This always gives a junction between the part and the product outlet orifice and thus prevents any risk of formation between the part and the outlet orifice, of a tight barrier by bonding the walls of the bag. The device for fixing the part is preferably movable in flexion and / or in rotation relative to the outlet pipe of the product. Thus the part can better resist deformations of the pocket.

Le dispositif de fixation comporte avantageusement une rotule creuse ; la rotule permet alors à la fois le passage du produit et un déplacement en rotation de la pièce.The fixing device advantageously comprises a hollow ball joint; the ball then allows both the passage of the product and a rotational movement of the part.

La pièce semi-rigide peut directement être moulée avec la tubulure de sortie du produit ou avec le dispositif de fixation.The semi-rigid part can be directly molded with the product outlet tubing or with the fixing device.

Selon un premier mode de réalisation, la pièce semi-rigide est une grille. Ses éléments longitudinaux et transversaux sont de préférence rectilignes et perpendiculaires, les éléments longitudinaux étant de préférence parallèles à l'axe longitudinal de la poche.According to a first embodiment, the semi-rigid part is a grid. Its longitudinal and transverse elements are preferably rectilinear and perpendicular, the longitudinal elements preferably being parallel to the longitudinal axis of the pocket.

Les éléments longitudinaux et transversaux de la grille sont avantageusement disposés dans deux plans parallèles, c'est-à-dire qu'ils se croisent et sont soudés les uns aux autres sans qu'il y ait une interpénétration. Les éléments longitudinaux et transversaux peuvent également présenter des ondulations dans des plans perpendiculaires au plan médian de la grille. Les éléments transversaux et longitudinaux peuvent également être en quelque sorte tissés.The longitudinal and transverse elements of the grid are advantageously arranged in two parallel planes, that is to say that they intersect and are welded to each other without any interpenetration. The longitudinal and transverse elements may also have undulations in planes perpendicular to the median plane of the grid. The transverse and longitudinal elements can also be somehow woven.

De préférence, sur la périphérie de la grille est disposé un cordon destiné à éviter que les extrémités des éléments longitudinaux et transversaux de la grille ne risquent de percer la paroi de la poche.Preferably, on the periphery of the grid is arranged a bead intended to prevent the ends of the longitudinal and transverse elements of the grid from risking piercing the wall of the pocket.

La dimension des mailles de la grille est suffisamment faible pour que les parois de la poche ne puissent pas se coller à l'intérieur de la maille. La plus grande dimension possible est donc fonction de la rigidité des parois de la poche et de la viscosité du produit distribué. Cette dimension est en général comprise entre 1,5 et 20 mm², par exemple de l'ordre de 9 mm².The mesh size of the grid is small enough that the walls of the pocket cannot stick to the inside of the mesh. The largest possible dimension is therefore a function of the rigidity of the walls of the bag and the viscosity of the product dispensed. This dimension is generally between 1.5 and 20 mm², for example of the order of 9 mm².

Selon un second mode de réalisation, la pièce est constituée de bandes semi-rigides séparées par des fentes et reliées entre elles à leurs extrémités, les bandes étant incurvées soit d'un côté, soit de l'autre du plan médian de la pièce, deux bandes voisines étant incurvées en sens inverse.According to a second embodiment, the part is made up of semi-rigid bands separated by slots and connected to each other at their ends, the bands being curved either on one side or on the other of the median plane of the part, two neighboring bands being curved in opposite directions.

Dans ce mode de réalisation, les bandes incurvées maintiennent les parois du sac écartées. Au fur et à mesure que la poche se vide, les parois de la poche appuient avec une force de plus en plus grande sur les bandes incurvées. Ces dernières qui ont une certaine flexibilité se déforment en direction du plan médian de la pièce. La distribution du produit restant dans la poche est ainsi facilitée.In this embodiment, the curved strips keep the walls of the bag apart. At as the pocket empties, the walls of the pocket press with increasing force on the curved strips. The latter, which have a certain flexibility, deform in the direction of the median plane of the part. The distribution of the product remaining in the pocket is thus facilitated.

Selon une réalisation particulière de l'ensemble selon l'invention, un dispositif formant réseau capillaire est fixé au voisinage de l'orifice de la tubulure de sortie entre la pièce et ladite tubulure, perpendiculairement à ladite grille. Ce dispositif a, notamment, une forme annulaire. Il peut être plein et comporter côté produit des canaux ou des nervures. Il peut également être constitué par une grille.According to a particular embodiment of the assembly according to the invention, a device forming a capillary network is fixed in the vicinity of the orifice of the outlet pipe between the part and said pipe, perpendicular to said grid. This device has, in particular, an annular shape. It can be full and have channels or ribs on the product side. It can also be constituted by a grid.

Ce dispositif complète l'action de la grille.This device completes the action of the grid.

L'ensemble de distribution selon l'invention représenté sur les figures 1 et 2 est désigné dans son ensemble par 1. Il comporte une poche souple 2 contenue dans une enceinte rigide 3 et une tête de distribution 4 montée sur un couvercle 5, la poche souple contenant comme pièce semi-rigide une grille libre 6. L'enceinte rigide 3 a, par exemple, une forme cylindrique et comporte une paroi latérale 31 et un fond 32. Dans ce fond 32 est ménagée une ouverture d'entrée d'air 33. Sur le rebord supérieur 34 de l'enceinte rigide 3, le couvercle 5 est fixé par emboîtement. Le couvercle 5 porte sur sa face tournée vers le récipient rigide 3 une jupe cylindrique 51 sur la paroi extérieure de laquelle est soudée la poche souple 2, en particulier par soudure ultrason rotative. Cette poche 2 est constituée par un tube en matériau plastique souple fermé à sa partie inférieure par une soudure 21. Le couvercle 5 comporte un goulot sur lequel est fixée par vissage ou claquage la tête de distribution 4 formant pompe, comportant deux valves et sans reprise d'air.The distribution assembly according to the invention shown in FIGS. 1 and 2 is designated as a whole by 1. It comprises a flexible pocket 2 contained in a rigid enclosure 3 and a distribution head 4 mounted on a cover 5, the pocket flexible containing as a semi-rigid part a free grid 6. The rigid enclosure 3 has, for example, a cylindrical shape and has a side wall 31 and a bottom 32. In this bottom 32 is formed an air inlet opening 33. On the upper edge 34 of the rigid enclosure 3, the cover 5 is fixed by interlocking. The cover 5 carries on its face facing the rigid container 3 a cylindrical skirt 51 on the outer wall of which the flexible bag 2 is welded, in particular by rotary ultrasonic welding. This pocket 2 is constituted by a tube of flexible plastic material closed at its lower part by a weld 21. The cover 5 comprises a neck on which is fixed by screwing or snapping the dispensing head 4 forming a pump, comprising two valves and without recovery of air.

La poche souple 2 contient une grille 6 à mailles bi-orientées en matière plastique souple. Cette grille 6, par exemple à mailles carrées, est constituée comme visible sur la figure 2 d' éléments longitudinaux 61 et d' éléments transversaux 62 situés dans deux plans parallèles, c' est-à-dire qu' ils se croisent et sont soudés les uns aux autres sans qu' il y ait interpénétration. Les éléments longitudinaux 61 et transversaux 62 présentent des ondulations 63 régulières comme apparent sur la figure 2. Cette grille a des dimensions inférieures à celles du sachet, ce qui lui permet de se déplacer au sein du produit et de mélanger ledit produit, mais sa longueur étant nettement supérieure à la largeur de la poche souple, elle ne peut se déplacer de manière importante.The flexible pocket 2 contains a grid 6 with bi-oriented mesh made of flexible plastic. This grid 6, for example with square meshes, is made up as visible in FIG. 2 of longitudinal elements 61 and of transverse elements 62 situated in two parallel planes, that is to say that they cross and are welded to each other without interpenetration. The longitudinal 61 and transverse 62 elements have regular undulations 63 as shown in FIG. 2. This grid has dimensions smaller than those of the sachet, which allows it to move within the product and to mix said product, but its length being significantly greater than the width of the flexible pouch, it can not move significantly.

La grille 6 reste dans sa position et ne peut se mettre dans une autre position où son plan moyen serait perpendiculaire à l'axe longitudinal de la poche.The grid 6 remains in its position and cannot be put in another position where its mean plane is perpendicular to the longitudinal axis of the pocket.

Les éléments longitudinaux 61 sont orientés sensiblement suivant la direction d' écoulement du produit vers la tête 4, c' est-à-dire verticalement selon la représentation de la figure 1. Ces éléments 61 déterminent des canaux 7 dirigés dans le sens général d' écoulement du produit. Les canaux 7 sont continus et libres d'obstacle puisque tous les éléments transversaux 62 passent au-dessus ou au-dessous des éléments 61.The longitudinal elements 61 are oriented substantially in the direction of flow of the product towards the head 4, that is to say vertically according to the representation in FIG. 1. These elements 61 determine channels 7 directed in the general direction of product flow. The channels 7 are continuous and free of obstacles since all the transverse elements 62 pass above or below the elements 61.

L'ensemble 1 fonctionne de la façon décrite ci-après. Lorsque l' utilisateur désire distribuer le produit contenu dans la poche souple 2, il appuie sur la tête de distribution 4 de façon à faire sortir le produit. Au fur et à mesure de la distribution la poche souple 2 se vide et les parois latérales se rapprochent. Les parois latérales sont maintenues espacées par la grille 6, et les canaux formés 7 permettent d' épuiser le produit.The assembly 1 operates in the manner described below. When the user wishes to dispense the product contained in the flexible bag 2, he presses on the dispensing head 4 so as to remove the product. As the distribution progresses, the flexible bag 2 empties and the side walls come closer. The side walls are kept spaced apart by the grid 6, and the formed channels 7 allow the product to be used up.

Les figures 3 et 4 représentent la poche souple 102 d'un ensemble de distribution selon l'invention. La poche souple 102 est fixée sur une tête de distribution analogue à celle représentée sur la figure 1, la tête de distribution est montée sur un couvercle 105 dont seule la jupe intérieure 151, sur laquelle est fixée par soudure la poche, est représentée. Cette jupe intérieure est constituée d'une partie cylindrique 151a sur laquelle est disposé le dispositif de fixation 108. Celui-ci est constitué de deux pattes symétriques en forme d'équerre 108a et 108b, la partie 181a ou 181b fixée à la jupe 151 étant perpendiculaire à l'axe longitudinal de la poche souple et la partie 182a ou 182b parallèle à l'axe étant dirigée vers le fond de la poche 102. L'extrémité libre de ces parties 182a et 182b porte un bourrelet 183, les bourrelets 183a et 183b se faisant vis-à-vis. La grille 106 est maintenue entre les pattes 108a et 108b, plus particulièrement entre les bourrelets 183a et 183b.Figures 3 and 4 show the flexible bag 102 of a dispensing assembly according to the invention. The flexible bag 102 is fixed to a dispensing head similar to that shown in FIG. 1, the dispensing head is mounted on a cover 105 of which only the inner skirt 151, on which the pocket is fixed by welding, is shown. This inner skirt consists of a cylindrical part 151 a on which is disposed the fixing device 108. This consists of two symmetrical brackets in the form of a square 108 a and 108 b , the part 181 a or 181 b fixed to the skirt 151 being perpendicular to the longitudinal axis of the flexible bag and the part 182 a or 182 b parallel to the axis being directed towards the bottom of the pocket 102. The free end of these parts 182 a and 182 b carries a bead 183, the beads 183 a and 183 b being made opposite. The grid 106 is held between the legs 108 a and 108 b , more particularly between the beads 183 a and 183 b .

La figure 5 représente un ensemble de distribution 201 en cours de montage. L'ensemble 201 comporte une poche souple 202 et une tête de distribution 204 montée sur un couvercle 205. Ledit couvercle comporte une jupe cylindrique 251 sur laquelle la poche 202 est fixée par soudure. La poche 202 contient une grille 206 et un dispositif formant réseau capillaire 209. La grille est fixée au dispositif 209 par un dispositif de fixation 208 constitué d'une rotule creuse 281 associée à une calotte sphérique 282 munie de fentes disposée au centre du dispositif formant réseau capillaire 209.FIG. 5 represents a distribution assembly 201 during assembly. The assembly 201 comprises a flexible pocket 202 and a dispensing head 204 mounted on a cover 205. The said cover comprises a cylindrical skirt 251 on which the pocket 202 is fixed by welding. The pocket 202 contains a grid 206 and a device forming a capillary network 209. The grid is fixed to the device 209 by a fixing device 208 consisting of a hollow ball 281 associated with a spherical cap 282 provided with slots arranged in the center of the device forming capillary network 209.

La rotule 281 est constituée de deux coquilles 281a et b fixées sur une couronne annulaire 281c. Ladite couronne 281c porte deux pattes 281d entre lesquelles la grille 206 est fixée. La rotule creuse 281 est montée par claquage dans la calotte sphérique 282. Lorsque la grille est montée le produit peut passer à travers la rotule 281 et la calotte 282 en direction de la tête de distribution. Le dispositif 209 formant réseau capillaire est, selon le mode de réalisation représenté sur la figure 5, fixé sur le rebord de la jupe cylindrique 251. Il est constitué par une grille comportant des éléments radiaux 291 et un élément annulaire 292. Ce dispositif 209 complète l'action de la grille 206 en empêchant les parois de la poche souple 202 d' être aspirées à l'intérieur du couvercle 205 et de bloquer l'ouverture de sortie du produit du récipient dans la tête 204.The ball 281 consists of two shells 281 a and b fixed on an annular ring 281 c . Said crown 281 c carries two tabs 281 d between which the grid 206 is fixed. The hollow ball 281 is mounted by snap in the spherical cap 282. When the grid is mounted the product can pass through the ball 281 and the cap 282 in the direction of the dispensing head. The device 209 forming a capillary network is, according to the embodiment shown in FIG. 5, fixed to the rim of the cylindrical skirt 251. It is constituted by a grid comprising radial elements 291 and an annular element 292. This device 209 completes the action of the grid 206 by preventing the walls of the flexible bag 202 from being sucked inside the cover 205 and blocking the opening for the product outlet from the container in the head 204.

Pour monter l'ensemble selon l'invention on claque la rotule 281 dans la calotte 282. On remplit la poche souple 202 avec le produit et on soude le bord 221 de la poche souple. On fixe ensuite par emboîtage le couvercle 205 sur le bord d'une enceinte rigide (non représentée) protégeant la poche souple.To mount the assembly according to the invention, the ball joint 281 is slammed into the cap 282. The flexible bag 202 is filled with the product and the edge 221 of the flexible bag is welded. The cover 205 is then fixed by fitting onto the edge of a rigid enclosure (not shown) protecting the flexible bag.

Les figures 6 et 7 représentent une pièce semi- rigide 306 selon le second mode de réalisation. La pièce 306 a en projection sur son plan médian une forme rectangulaire. Elle est constituée de trois bandes incurvées 361a, 361b, 361c séparées par des fentes 362a et 362b. Les bandes 361a, 361b, 361c sont reliées à une de leurs extrémités à une bande transversale plane 363 et à leur autre extrémité à une autre bande transversale plane 364 portant deux pattes 365 de fixation à un dispositif de fixation à la tubulure de sortie du produit distribué (non représenté).Figures 6 and 7 show a semi-rigid part 306 according to the second embodiment. The part 306 has in projection on its median plane a rectangular shape. It consists of three curved strips 361a, 361b, 361c separated by slots 362a and 362b. The strips 361a, 361b, 361c are connected at one of their ends to a planar transverse strip 363 and at their other end to another planar transverse strip 364 carrying two tabs 365 for fixing to a device for fixing to the product outlet pipe. distributed (not shown).

Les bandes 361a et 361c sont incurvées de façon à faire saillie d'un côté du plan médian M et la bande du milieu 361b est incurvée de façon à faire saillie systématiquement de l'autre côté du plan médian M.The bands 361a and 361c are curved so as to project from one side of the median plane M and the middle band 361b is curved so as to systematically project from the other side of the median plane M.

La pièce représentée sur les figures 6 et 7 comporte trois bandes. Il faut noter que le nombre de bandes pourrait être plus élevé.The part shown in Figures 6 and 7 has three bands. Note that the number of bands may be higher.
