Description

La présente invention concerne un distributeur de produit fluide comprenant une coque sensiblement rigide ainsi qu'une poche souple destinée à contenir le produit fluide à distribuer. Pour extraire le produit fluide de la poche souple, on utilise un organe de distribution telle qu'une pompe. Pour la fixation de l'organe de distribution sur la poche souple, il est déjà connu d'utiliser une pièce intermédiaire qui sert d'une part de support pour la poche et d'autre part de douille de fixation pour la pompe. Un tel distributeur est notamment divulgué dans le document US-5 873 491. La pièce intermédiaire que l'on peut appeler support de poche comprend dans ce distributeur de l'art antérieur un plateau périphérique qui est encliqueté sur sa périphérie extérieure à l'intérieur de la coque. La coque est fermée au niveau de son fond et présente une ouverture maximale à travers laquelle la poche souple et son support de poche sont introduits pour compléter le distributeur. Etant donné que la poche et son support sont introduits dans la coque par le haut, il est possible de monter préalablement la pompe sur le support de poche.The present invention relates to a fluid dispenser comprising a substantially rigid shell and a flexible pouch for containing the fluid product distribute. In order to extract the fluid product from the flexible bag, an organ of distribution such as a pump. For fixing the dispensing member on the pocket flexible, it is already known to use an intermediate part which serves on the one hand support for the pocket and on the other hand fixing sleeve for the pump. Such a distributor is disclosed in US-5,873,491. The intermediate piece that can be called pocket holder includes in this prior art dispenser a tray device that is snapped on its outer periphery inside the hull. The shell is closed at its bottom and has a maximum opening through which the flexible pouch and its pocket support are introduced to complete the distributor. Since the bag and its support are introduced into the hull by the high, it is possible to pre-mount the pump on the pocket support.

On a remarqué avec ce type de distributeur de l'art antérieur qu'il était possible de désencliqueter le support de poche de la coque en manipulant de manière incorrecte ou maladroite l'organe de distribution. Par conséquent, la fixation du support de poche sur la coque n'est pas fiable.It has been noted with this type of distributor of the prior art that it was possible to disengage the hull pocket support by improperly handling or clumsy the organ of distribution. Therefore, fixing the pocket support on the hull is not reliable.

Dans l'art antérieur, le document EP-0 638 367 décrit un distributeur comprenant une coque rigide avec un col, un réservoir avec un col et une pompe. Le fond de la coque est ouvert et le réservoir est inséré dans la coque par son fond ouvert. Le col de la coque forme une denture annulaire interne qui coopère avec une denture complémentaire formée à l'extérieur du col du réservoir. Ces dentures imbriquées servent de moyens de blocage en rotation. La fixation du réservoir dans la coque est réalisée par le vissage d'une bague de fixation de la pompe sur un filetage formé par le col du réservoir. Il s'agit d'un distributeur rechargeable où le réservoir peut être facilement remplacé. C'est pourquoi le réservoir n'est pas définitivement fixé à la coque, ni à la pompe. On ne peut même pas parler de fixation sur la coque, encore moins définitive, puisque le réservoir n'est pas solidaire de la coque, si l'on vient à soulever cette dernière. A vrai dire, le blocage en rotation n'est pas nécessaire pour la fixation qui est assuré entièrement par le vissage de la pompe. D'autre part le réservoir 1 n'est pas une poche souple soudée sur un support. In the prior art, EP-0 638 367 discloses a dispenser comprising a rigid hull with a collar, a tank with a neck and a pump. The bottom of the hull is open and the tank is inserted into the hull by its open bottom. The neck of the hull forms an internal annular toothing which cooperates with a complementary toothing formed outside the reservoir neck. These nested teeth serve as locking means in rotation. The fixing of the tank in the shell is carried out by screwing a ring of fixing the pump on a thread formed by the neck of the tank. This is a distributor rechargeable where the tank can be easily replaced. That's why the tank is not permanently attached to the hull or the pump. We can not even talk about fixation on the hull, even less definitive, since the tank is not attached to the hull, if we come to lift the latter. Actually, blocking in rotation is not necessary for fixing which is ensured entirely by the screwing of the pump. On the other hand, tank 1 is not a flexible pouch welded to a support.

La présente invention a pour but de surmonter les inconvénients de l'art antérieur en définissant un distributeur dont le support de poche est fixé de manière solide et définitive à la coque rigide, indépendamment de la fixation de la pompe.The present invention aims to overcome the disadvantages of the prior art by defining a dispenser whose pocket support is firmly and definitively fixed with the rigid hull, independently of the fixing of the pump.

Pour ce faire, la présente invention propose un distributeur de produit fluide comprenant une coque sensiblement rigide présentant une ouverture, une poche souple fixée à un support de poche formant une douille de fixation définissant un passage de sortie pour le produit fluide et un organe de distribution, tel qu'une pompe, monté dans le passage de sortie du support de poche pour extraire du produit fluide, la douille de fixation du support de poche étant fixée de l'intérieur dans l'ouverture de la coque. Il va de soi que le fond de la coque rigide est ouvert et obturable au moyen d'une pièce de fond rapportée. Le support de poche est donc inséré à l'intérieur de la coque rigide par son fond ouvert et fixé en position dans l'ouverture de la coque. Une fois la pompe montée, il est impossible de désolidariser le support de poche de la coque rigide, puisque la pompe est située à l'extérieur de la pompe et la majeure partie du support de poche est située à l'intérieur de la coque.To do this, the present invention provides a fluid dispenser comprising a substantially rigid shell having an opening, a flexible pouch attached to a pocket holder forming a fixing sleeve defining an exit passage for the fluid product and a dispensing member, such as a pump, mounted in the outlet passage of the pocket holder for extracting fluid, the fixing sleeve the pocket support being fixed from the inside in the opening of the shell. It's obvious that the bottom of the rigid shell is open and closable by means of a bottom piece reported. The pocket holder is inserted inside the rigid shell by its open bottom and fixed in position in the opening of the hull. Once the pump rises, it is impossible to separate the pocket support from the rigid shell, since the pump is located at the outside of the pump and most of the pocket support is located inside the shell.

Un autre avantage de cette fixation de la poche dans la coque est qu'elle ne fait pas intervenir l'organe de distribution (pompe). De ce fait, la poche est solidaire de la coque en l'absence de la pompe. Il est donc possible de remplir la poche alors q'elle est déjà fixée dans la coque. De plus, la coque sert de support à la poche et améliore ainsi sa tenue lors de son remplissage mais aussi lors de la fixation de la pompe. Ceci n'est pas le cas avec le distributeur du document EP-0 638 367.Another advantage of this fixing of the pocket in the hull is that it does not intervene the dispensing member (pump). As a result, the pocket is secured to the shell in the absence of the pump. It is therefore possible to fill the pocket while it is already fixed in the hull. In addition, the shell serves as a support for the pocket and thus improves its performance during filling but also when fixing the pump. This is not the case with the distributor of EP-0 638 367.

Pour la fixation du support de poche, la douille de fixation comprend un profil d'encliquetage destiné à coopérer par encliquetage avec l'ouverture de la coque. Dans ce cas, il suffit d'engager le support de poche à l'intérieur de la coque et de le forcer dans l'ouverture de la coque jusqu'à encliquetage.For fixing the pocket support, the fixing sleeve comprises a profile detent for cooperating by snapping with the opening of the shell. In this case, simply engage the pocket holder inside the hull and force it into the opening of the hull until snapping.

Selon une première forme de réalisation, l'organe de distribution est fixé sur la douille de fixation. La douille de fixation sert ici d'organe d'encliquetage sur la coque ainsi que d'organe pour la fixation de la pompe. Avantageusement, l'organe de distribution vient en contact d'appui sur la coque rigide. Ainsi, la coque est pour ainsi dire coincée entre la pompe et le support de poche sur lequel elle est encliquetée. On voit clairement qu'il est impossible de séparer le support de poche de la coque simplement en agissant sur la pompe.According to a first embodiment, the dispensing member is fixed on the fixing sleeve. The fixing sleeve serves here as a detent member on the shell as well that of organ for fixing the pump. Advantageously, the distribution member comes in bearing contact on the rigid shell. So the hull is pretty much stuck between the pump and the pocket support on which it is snapped. We clearly see that he is it is impossible to separate the pouch holder from the hull simply by acting on the pump.

Selon une seconde forme de réalisation, l'ouverture de la coque est formée par un col qui fait saillie vers l'extérieur de la coque, ladite douille de fixation étant fixée à l'intérieur du col. Dans ce cas, l'organe de distribution peut être fixé sur le col de la coque. Le support de poche est donc fixé, par exemple par encliquetage, à l'intérieur du col de la coque et la pompe est fixée, par exemple par encliquetage, sur le col de la coque. Ici, le col sert de moyen de fixation à la fois pour le support de poche et la pompe. Là encore, on voit qu'il est clairement impossible de désolidariser le support de poche simplement en agissant sur la pompe d'autant plus qu'il n'y aucun lien mécanique direct entre le support de poche et la pompe.According to a second embodiment, the opening of the shell is formed by a collar protruding outwardly from the shell, said fixing sleeve being secured to the inside of the collar. In this case, the dispenser member may be attached to the neck of the shell. The support pocket is therefore fixed, for example by snapping, inside the neck of the shell and the pump is fixed, for example by snapping, on the neck of the hull. Here, the collar serves as fastening means for both the pocket holder and the pump. Again, we see that it is clearly impossible to separate the pocket support simply by acting on the pump especially as there is no direct mechanical connection between the pocket holder and the pump.

Dans le cas où la douille de fixation du support de poche est encliquetée à l'intérieur du col de la coque, il est avantageux que le col de la coque soit déformable élastiquement radialement vers l'extérieur pour permettre le passage de la douille de fixation dans le col. La déformabilité élastique du col permet de faciliter l'encliquetage de la douille de fixation du support de poche. Dans une forme de réalisation pratique, le col de la coque est formé avec au moins une fente verticale permettant une dilatation radiale du col lors de la mise en place de la douille de fixation. La fixation ultérieure de la pompe, par exemple par encliquetage, sur le col de la coque permet de verrouiller l'encliquetage de la douille dans le col. En effet, une fois la pompe montée sur le col déformable, celui-ci ne peut plus subir de déformation idéale vers l'extérieur.In the case where the fixing sleeve of the pocket holder is snapped inside of the neck of the shell, it is advantageous for the neck of the shell to be elastically deformable radially outwardly to allow passage of the fixing sleeve in the neck. The elastic deformability of the neck makes it easier to snap the fastening sleeve of the pocket support. In a practical embodiment, the neck of the shell is formed with at least one vertical slot allowing radial expansion of the neck when place of the fixing sleeve. The subsequent fixing of the pump, for example by snap on the neck of the shell to lock the snap of the socket in the collar. Indeed, once the pump mounted on the deformable collar, it can no longer undergo ideal deformation to the outside.

Selon une réalisation pratique, le col est formé avec une rainure d'encliquetage interne pour l'encliquetage de la douille de fixation et une gorge d'encliquetage externe pour l'encliquetage de l'organe de distribution.In a practical embodiment, the neck is formed with a snap groove internally for snap-fastening socket and external snap groove for latching the dispensing member.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif deux modes de réalisation de la présente invention. Sur les figures :

  • la figure 1 est une vue éclatée en section transversale verticale à travers un distributeur selon la présente invention,
  • la figure 2 est une vue de profil du distributeur de la figure 1,
  • la figure 3 est une vue de dessus du distributeur des figures 1 et 2 avec l'organe de distribution enlevé,
  • la figure 4 est une vue agrandie en section transversale à travers le distributeur des figures 1 à 3 à l'état assemblé, et
  • la figure 5 est une vue en section transversale à travers un distributeur selon une seconde forme de réalisation, l'organe de distribution étant omis.
The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example two embodiments of the present invention. In the figures:
  • FIG. 1 is an exploded view in vertical cross section through a dispenser according to the present invention,
  • FIG. 2 is a profile view of the dispenser of FIG. 1,
  • FIG. 3 is a view from above of the dispenser of FIGS. 1 and 2 with the dispenser member removed,
  • FIG. 4 is an enlarged cross-sectional view through the distributor of FIGS. 1 to 3 in the assembled state, and
  • Figure 5 is a cross-sectional view through a dispenser according to a second embodiment, the dispensing member being omitted.

Dans les deux formes de réalisation utilisées pour illustrer la présente invention, le distributeur de produit fluide comprend une coque sensiblement rigide 1, un support de poche 2, sur lequel une poche souple est fixée, et un organe de distribution tel qu'une pompe.In both embodiments used to illustrate the present invention, the fluid dispenser comprises a substantially rigid shell 1, a support of pocket 2, on which a flexible pouch is attached, and a dispensing member such as a pump.

La coque peut masquer la totalité de la poche comme dans l'exemple décrit ci-après. Cependant, la coque peut également se présenter sous la forme d'une enveloppe n'entraínant que la partie supérieure de la poche pour laisser apparaítre sa partie inférieure.The shell can mask the entire pocket as in the example described below. However, the shell may also be in the form of an envelope only driving the upper part of the pocket to reveal its lower part.

Sur les figures, la coque sensiblement rigide 1 comprend un corps 10, ici sensiblement cylindrique, mais qui peut également présenter d'autres formes esthétiques ou même fonctionnelles. A son extrémité supérieure. le corps 10 forme un épaulement 12 qui définit, de préférence de manière centrale. une ouverture 14 de dimension sensiblement réduite. A son extrémité inférieure, le corps 10 est largement ouvert et peut optionnellement être obturé par une pièce de fond. Par conséquent, l'intérieur de la coque est aisément accessible par son fond ouvert 11. En regardant à l'intérieur de la coque par son fond largement ouvert 11, on voit l'ouverture 14 de dimension réduite au niveau de l'épaulement 12.In the figures, the substantially rigid shell 1 comprises a body 10, here substantially cylindrical, but which may also present other aesthetic forms or even functional. At its upper end. the body 10 forms a shoulder 12 which defines, preferably centrally. an opening 14 of substantially reduced size. AT its lower end, the body 10 is widely open and can optionally be closed by a bottom room. Therefore, the inside of the hull is easily accessible by its open bottom 11. Looking inside the hull by its bottom widely open 11, we see the opening 14 of reduced size at the shoulder 12.

Le support de poche 2 comprend un appendice de soudage 21 formé avec des nervures 210. La poche souple 23 est soudée par l'appendice de soudage 21 de sorte que l'appendice 21 pénètre à l'intérieur de l'ouverture de la poche souple. Au-dessus de l'appendice de soudage 21, le support de poche 2 définit un plateau 20 à partir duquel fait saillie une douille de fixation 22. L'appendice de soudage 21 et la douille de fixation 22 définissent un trou de passage 24 qui fait communiquer l'intérieur de la poche 23 avec l'extérieur.The pocket support 2 comprises a welding appendage 21 formed with ribs 210. The flexible pouch 23 is welded by the welding appendage 21 so that Appendix 21 penetrates inside the opening of the flexible pouch. Above the welding appendix 21, the pocket support 2 defines a plate 20 from which protruding a fixing sleeve 22. The welding appendage 21 and the fixing sleeve 22 define a through hole 24 which communicates the inside of the pocket 23 with outside.

Selon l'invention, la douille de fixation 22 du support de poche 2 est fixée dans l'ouverture 14 de la coque rigide 1 de l'intérieur, c'est-à-dire en faisant passer le support de poche 2 à l'intérieur de la coque 1 par son fond ouvert 11 pour amener la douille de fixation dans l'ouverture 14 de la coque 1. La fixation du support de poche dans l'ouverture 14 peut être réalisée par n'importe quelle technique, par exemple par vissage ou encliquetage. Dans une forme de réalisation de l'invention représentée sur la figure 5, l'ouverture 14 de la coque 1 est simplement réalisée par une perforation de l'épaulement 12. D'autre part, la douille de fixation 22 du support de poche 2 est réalisée par une bride d'encliquetage 221 destinée à venir en prise d'encliquetage avec le bord de l'ouverture 14. Pour ce faire, on amène le support de poche 2 à l'intérieur de la coque 1 et l'on engage la douille de fixation 22 à l'intérieur de l'ouverture 14 et par une pression appropriée, on fait passer la bride 221 de l'autre côté de l'ouverture 14 comme représenté sur la figure 5. Une fois en place, le support de poche 2 est définitivement solidaire de la coque rigide 1. Il suffit ensuite de monter une pompe sur la douille de fixation 22 du support de poche 2 pour compléter le distributeur.According to the invention, the fixing sleeve 22 of the pocket support 2 is fixed in the opening 14 of the rigid shell 1 from the inside, that is to say by passing the support of pocket 2 inside the shell 1 by its open bottom 11 to bring the sleeve of fixing in the opening 14 of the shell 1. The attachment of the pocket support in the opening 14 can be achieved by any technique, for example by screwing or snap. In one embodiment of the invention shown in FIG. 5, the opening 14 of the shell 1 is simply made by a perforation of the shoulder 12. On the other hand, the fixing sleeve 22 of the pocket support 2 is made by a flange snap-fastener 221 for snap engagement with the edge of the opening 14. To do this, bring the pocket support 2 inside the shell 1 and engage the fixing sleeve 22 inside the opening 14 and by appropriate pressure, it is pass the flange 221 on the other side of the opening 14 as shown in FIG. once in place, the pocket support 2 is permanently attached to the rigid shell 1. It is sufficient then to mount a pump on the fixing sleeve 22 of the pocket support 2 for complete the distributor.

Dans le mode de réalisation représenté sur les figures 1 à 4, l'ouverture 14 de la coque rigide 1 est formée par un col 13 qui fait saillie vers l'extérieur de la coque 1. Le col 13 présente des profils intérieur et extérieur destinés à coopérer avec le support de poche 2 et la pompe. Selon une forme de réalisation pratique, le col 13 forme intérieurement une rainure d'encliquetage 131 et la douille 22 du support de poche 2 forme un cordon d'encliquetage 221 destiné à venir en prise d'encliquetage dans la rainure 131. D'autre part, le col 13 forme extérieurement une gorge d'encliquetage destinée à coopérer par encliquetage avec un cordon d'encliquetage 30 formé par une bague de fixation 31 de la pompe 3. Pour faciliter la mise en place du support de poche 2 à l'intérieur du col 13, on peut réaliser le col 13 avec des fentes verticales 132, par exemple au nombre de quatre, comme représenté sur la figure 3, qui confère au col une caractéristique d'élasticité de sorte que les quatre segments de col ainsi définis peuvent être déformés radialement vers l'extérieur lors du passage du cordon 221 à l'intérieur du col 13 pour regagner finalement la rainure d'encliquetage 131 formée par le col 13. Le verrouillage définitif du support de poche dans le col 13 est réalisé par la mise en place de l'organe de distribution 3 sur le col 13 qui verrouille définitivement l'encliquetage du support de poche 2. Il est à noter que dans cette forme de réalisation, la pompe 3 n'est pas en contact mécanique avec le support de poche 2, puisqu'ils sont encliquetés tous deux sur le même organe c'est-à-dire le col 13 de la coque 1. Il est donc strictement impossible de désencliqueter le support de poche en agissant sur la pompe. Il en est de même dans la version représentée sur la figure 5, bien que la pompe soit directement fixée sur la douille de fixation. En effet, si l'on retire la pompe de la douille, le support de la poche reste encliqueté dans l'ouverture 14 de la coque rigide.In the embodiment shown in FIGS. 1 to 4, the opening 14 of the rigid shell 1 is formed by a neck 13 which protrudes outwardly of the shell 1. The neck 13 has inner and outer profiles for cooperating with the pocket support 2 and the pump. According to a practical embodiment, the neck 13 internally forms a snap groove 131 and the socket 22 of the pocket support 2 form a cord detent 221 for engaging snap-fit in the groove 131. On the other hand, the neck 13 externally forms a latching groove intended to cooperate by latching with a detent cord 30 formed by a fixing ring 31 of the pump 3. To facilitate the introduction of the pocket support 2 inside the neck 13, it is can achieve the neck 13 with vertical slots 132, for example four in number, as shown in FIG. 3, which gives the collar a characteristic of elasticity so that that the four neck segments thus defined can be deformed radially towards outside during the passage of the cord 221 inside the neck 13 to finally regain the snap groove 131 formed by the neck 13. The final locking of the support of pocket in the neck 13 is achieved by the establishment of the dispensing member 3 on the neck 13 which permanently locks the snap of the pocket holder 2. It should be noted that in this embodiment, the pump 3 is not in mechanical contact with the support 2, since they are both latched on the same organ that is to say the neck 13 of the hull 1. It is therefore strictly impossible to disengage the pocket support in acting on the pump. It is the same in the version shown in Figure 5, although the pump is directly attached to the mounting sleeve. Indeed, if we remove the pump of the sleeve, the support of the pocket remains latched in the opening 14 of the hull rigid.
