The dispenser neck (41) is connected by film hinges (48, 49) to both the handle (43) and the cap (42).

Description

La présente invention concerne un ensemble distributeur pour délivrer un produit liquide ou pâteux contenu dans une poche souple munie d'un système de fermeture automatique qui s'ouvre ou se ferme, pour délivrer le produit sans reprise d'air, selon que le produit est, à travers la poche souple, soumis ou non à une pression suffisante, la poche souple étant, mis à part son système de fermeture automatique, logée étanche dans un flacon dont l'enveloppe est munie d'un passage obturable pour, en cas de fermeture du passage obturable, pouvoir comprimer l'air alors emprisonné entre la poche et le flacon, et ainsi comprimer uniformément la poche pour délivrer le produit.The present invention relates to a dispenser assembly for delivering a liquid or pasty product contained in a flexible bag provided with an automatic closing system which opens or closes, to deliver the product without air intake, depending on whether the product is , through the flexible bag, subject or not to sufficient pressure, the flexible bag being, apart from its automatic closure system, housed sealed in a bottle whose envelope is provided with a closable passage for, in case of closing the closable passage, being able to compress the air then trapped between the pocket and the bottle, and thus uniformly compress the pocket to deliver the product.

Un tel ensemble distributeur présente l'avantage qu'il est manoeuvrable avec une seule main et que le produit est protégé contre les agressions de l'environnement, par exemple : les poussières ou le sable en cas de chute à terre du flacon, l'eau s'il tombe dans la baignoire ou dans la mer, l'air enfin qui oxyde les produits et empêche une conservation optimale avec des concentrations minimales de conservateurs chimiques.Such a dispenser assembly has the advantage that it can be operated with one hand and that the product is protected against environmental aggressions, for example: dust or sand in the event of the bottle falling to the ground, the water if it falls in the bathtub or in the sea, finally the air which oxidizes the products and prevents optimal conservation with minimum concentrations of chemical preservatives.

Dans FR-A-2 389 419, un ensemble distributeur est décrit dans lequel l'enveloppe du flacon est déformable élastiquement dans son ensemble ; en outre, il est prévu que le passage obturable de l'enveloppe soit obturé par le doigt de l'usager dont la main tient l'enveloppe pour exercer directement sur celle-ci la pression nécessaire pour délivrer le produit. Cet agencement oblige donc l'usager à être attentif à positionner un doigt en vis-à-vis du passage obturable. De plus la quantité de produit délivrée dépend essentiellement de la force exercée par la main de l'usager, et peut même, accidentellement, être tout à fait excessive.In FR-A-2 389 419, a dispenser assembly is described in which the envelope of the bottle is elastically deformable as a whole; in addition, provision is made for the closable passage of the envelope to be closed by the finger of the user whose hand is holding the envelope so as to directly exert on it the pressure necessary to deliver the product. This arrangement therefore requires the user to be careful to position a finger vis-à-vis the closable passage. In addition, the quantity of product delivered essentially depends on the force exerted by the user's hand, and may even, accidentally, be entirely excessive.

Selon US-A-3 223 289, on a déjà proposé de déformer une partie de la paroi du flacon contenant la poche souple afin d'expulser une quantité de produit de l'ensemble distributeur ; malheureusement, là encore, la quantité de produit délivrée dépend de la manoeuvre de l'usager.According to US-A-3,223,289, it has already been proposed to deform a part of the wall of the bottle containing the flexible bag in order to expel a quantity of product from the dispenser assembly; unfortunately, here again, the quantity of product delivered depends on the maneuver of the user.

La présente invention a pour but, notamment, de remédier aux inconvénients ci-dessus et propose, d'une manière particulièrement économique, de munir l'ensemble distributeur d'un dispositif agencé pour délivrer sensiblement la même quantité de produit, quel que soit le doigté de la manoeuvre de l'usager, et protégé contre des manoeuvres maladroites.The object of the present invention is, in particular, to remedy the above drawbacks and proposes, in a particularly economical manner, to provide the dispenser assembly with a device designed to deliver substantially the same quantity of product, whatever the fingering of the user's maneuver, and protected against clumsy maneuvers.

Un soufflet est un dispositif connu, par exemple par US-A-4 087 024, et l'on sait qu'à chaque manoeuvre il comprime la quantité d'air présente dans le flacon et permet la délivrance d'une quantité de produit ; à la fin de chaque manoeuvre, pour délivrer à nouveau du produit, il est évidemment nécessaire de réarmer le soufflet et, donc, l'écoulement d'un excès de produit n'est plus à craindre ; il suffit même de dimensionner le soufflet adéquatement pour n'obtenir que la quantité de produit désirée, et ainsi l'ensemble distributeur fait aussi office de doseur. Malheureusement, un soufflet est un organe relativement fragile qui peut s'user prématurément par des manoeuvres maladroites, par exemple désaxées.A bellows is a known device, for example by US-A-4 087 024, and it is known that at each operation it compresses the amount of air present in the bottle and allows the delivery of a quantity of product; at the end of each maneuver, to deliver the product again, it is obviously necessary to rearm the bellows and, therefore, the flow of an excess of product is no longer to be feared; it is even enough to dimension the bellows adequately to obtain only the quantity of product desired, and thus the dispenser assembly also acts as a metering device. Unfortunately, a bellows is a relatively fragile organ which can wear out prematurely by clumsy maneuvers, for example off-axis.

La présente invention a donc pour objet un ensemble distributeur tel que défini précédemment caractérisé par le fait que l'enveloppe du flacon comporte un élément en forme de soufflet, lequel soufflet est l'unique partie déformable élastiquement de l'enveloppe du flacon dont les autres parois sont relativement rigides, l'ensemble distributeur comportant en outre une poignée articulée manoeuvrable manuellement pour comprimer le soufflet. Ainsi, est imposée à l'usager une direction unique de manoeuvre au moyen d'une poignée articulée autour d'une charnière, ce qui protège le soufflet contre des manoeuvres maladroites.The present invention therefore relates to a dispenser assembly as defined above, characterized in that the envelope of the bottle comprises a bellows-shaped element, which bellows is the only elastically deformable part of the envelope of the bottle, the others of which walls are relatively rigid, the distributor assembly further comprising an articulated handle which can be operated manually to compress the bellows. Thus, the user is imposed a single direction of operation by means of a handle articulated around a hinge, which protects the bellows against clumsy operations.

Avantageusement, l'ensemble distributeur est caractérisé par le fait que ledit passage obturable est aménagé sur la paroi externe du soufflet, et que ladite poignée est munie intérieurement, en vis-à-vis du passage obturable, d'un élément en relief agencé pour venir obturer le passage obturable lors de la manoeuvre de la poignée. Ainsi, la fermeture du passage obturable pour emprisonner l'air s'effectue automatiquement et l'usager n'a plus à être attentif à la position de son doigt en face du passage.Advantageously, the dispenser assembly is characterized by the fact that said closable passage is arranged on the external wall of the bellows, and that said handle is provided internally, opposite the closable passage, with an element in relief arranged for close off the closable passage when the handle is operated. Thus, the closing of the closable passage to trap the air takes place automatically and the user no longer has to be attentive to the position of his finger opposite the passage.

Divers éléments d'obturation en relief sont envisageables, mais avantageusement, il est prévu dans la poignée un bossage en forme de couronne pour venir s'appliquer autour du passage obturable.Various obturation elements in relief can be envisaged, but advantageously, there is provided in the handle a boss in the form of a crown to come to be applied around the closable passage.

Il existe divers systèmes connus de fermeture automatique pour la poche souple mais, avantageusement, on peut prévoir un dôme muni d'une fente, et un corps de forme générale tronconique qui prend appui sur le dôme pour maintenir la fente fermée en l'absence d'une pression suffisante sur le produit, le dôme étant assemblé étanche sur la poche souple. Un tel système a déjà été proposé par exemple dans US-A-1 935 089.There are various known automatic closing systems for the flexible bag but, advantageously, one can provide a dome provided with a slot, and a body of generally frustoconical shape which bears on the dome to keep the slot closed in the absence of 'sufficient pressure on the product, the dome being assembled sealed on the flexible bag. Such a system has already been proposed for example in US-A-1,935,089.

Avantageusement, le flacon est muni d'un goulot comportant une face d'appui annulaire et une collerette de claquage, la poche souple et le dôme comportent chacun une collerette, et le corps tronconique comporte une face d'appui annulaire et un anneau de claquage, l'ensemble étant agencé pour réaliser, par encliquetage, un assemblage étanche du dôme sur la poche souple. L'ensemble distributeur ainsi réalisé est particulièrement économique car chacun de ses éléments est moulable, leur assemblage se faisant par un simple encliquetage.Advantageously, the bottle is provided with a neck comprising an annular bearing face and a snap-on flange, the flexible pocket and the dome each have a flange, and the frustoconical body comprises an annular support face and a snap-on ring. , the assembly being arranged to produce, by snap-fastening, a tight assembly of the dome on the flexible bag. The dispenser assembly thus produced is particularly economical because each of its elements is moldable, their assembly being done by a simple snap-fastening.

On peut encore prévoir que l'ensemble distributeur comporte en outre une capsule de fermeture de sécurité articulée autour d'une charnière film aménagée sur le corps tronconique pour venir coiffer le dôme ; de même on peut prévoir que la poignée est articulée autour d'une charnière film aménagée sur le corps tronconique ; on sait en effet que certaines matières plastiques se prêtent particulièrement bien à la constitution de charnières en prévoyant une épaisseur assez faible à l'endroit désiré. Ainsi, le corps tronconique, la poignée articulée, et la capsule articulée, constituent une seule et même pièce moulée. Le résultat est que l'ensemble distributeur selon l'invention est non seulement très économique de par son mode de fabrication, mais encore, il est facilement manoeuvrable par l'usager ; il protège le produit contre les agressions de l'environnement, et enfin il délivre la dose prescrite lors de chaque manoeuvre.It is also possible to provide that the dispenser assembly also includes a closure capsule. security articulated around a film hinge arranged on the frustoconical body to cover the dome; similarly it can be provided that the handle is articulated around a film hinge arranged on the frustoconical body; it is known in fact that certain plastics lend themselves particularly well to the constitution of hinges by providing a fairly small thickness at the desired location. Thus, the frustoconical body, the articulated handle, and the articulated capsule, constitute a single molded part. The result is that the dispenser assembly according to the invention is not only very economical in terms of its manufacturing method, but also, it is easily maneuverable by the user; it protects the product against environmental aggressions, and finally it delivers the prescribed dose during each maneuver.

Pour mieux faire comprendre l'objet de la présente invention, on va en décrire, ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the present invention, there will be described below, by way of purely illustrative and not limiting, an embodiment shown in the accompanying drawing.

On this drawing :

  • Figure 4, with its detail in Figure 4 has again shown, in section, the same dispenser assembly but in use.

La vue éclatée de la figure 1 montre un flacon 5, une poche 2 souple, un dôme 3 et un activateur 4 ; tous ces éléments sont moulables par exemple en matière plastique.The exploded view of Figure 1 shows a bottle 5, a flexible bag 2, a dome 3 and an activator 4; all these elements can be molded, for example from plastic.

L'activateur 4 comporte trois parties principales, une poignée 43, un corps 41 et une capsule 42 ; ces trois parties sont reliées par des articulations 48, 49, par exemple des charnières film souple.The activator 4 has three main parts, a handle 43, a body 41 and a capsule 42; these three parts are connected by joints 48, 49, for example flexible film hinges.

Le corps 41 est de forme générale cylindrique terminée par une partie tronconique du côté supérieur ; la partie sensiblement cylindrique comporte intérieurement une face 46 d'appui annulaire et dans sa partie basse un anneau 45 de claquage.The body 41 is of generally cylindrical shape terminated by a frustoconical part on the upper side; the substantially cylindrical part has internally a face 46 of annular support and in its lower part a snap ring 45.

La capsule 42, articulée autour de la charnière souple 49, a une forme générale tronconique correspondant à celle du corps 41 pour venir le coiffer lorsque la capsule 42 vient basculer au-dessus du corps 41.The capsule 42, articulated around the flexible hinge 49, has a generally frustoconical shape corresponding to that of the body 41 so as to cap it when the capsule 42 comes to tilt above the body 41.

La poignée 43, qui peut pivoter vers le bas autour de l'articulation 48, a une forme générale en U ouvert vers le bas ; la partie centrale du U est munie intérieurement d'un bossage 44 en forme de couronne annulaire.The handle 43, which can pivot down around the articulation 48, has a general U-shape open downwards; the central part of the U is internally provided with a boss 44 in the form of an annular crown.

On voit que l'activateur 4 peut ne constituer qu'une seule pièce moulée ; en effet seul l'anneau 45 de claquage peut présenter une difficulté de démoulage mais, dans ce cas, on peut prévoir qu'il soit pourvu de lentes radiales pour l'assouplir.It is seen that the activator 4 can constitute only one molded part; in fact, only the snap ring 45 can present a difficulty in demolding, but in this case, provision can be made for it to be provided with radial nits to soften it.

Le dôme 3 a une forme générale de tétine pourvue d'une fente 32 de distribution et d'une collerette 31 annulaire.The dome 3 has a general shape of a teat provided with a distribution slot 32 and an annular collar 31.

La poche 2 souple, destinée à contenir le produit, peut avoir une forme générale quelconque, mais de préférence cylindrique ; la poche 2 souple ne comporte qu'une ouverture 22 munie d'une collerette 21 annulaire.The flexible pouch 2, intended to contain the product, may have any general shape, but preferably cylindrical; the flexible pocket 2 only has an opening 22 provided with an annular collar 21.

Le flacon 5 a une forme générale cylindrique ou parallélépipédique dont les parois 53 sont relativement rigides ; une face du flacon 5 est munie d'un soufflet 51 dont la paroi 54 manoeuvrable comporte un passage 52 obturable, par exemple une petite ouverture cylindrique ; le soufflet 51 qui relie d'une manière étanche la paroi 54 aux parois 53 possède évidemment la souplesse nécessaire à la manoeuvre du soufflet ; le flacon 5 est muni d'un goulot 57 lequel se termine par une face 56 d'appui annulaire sous laquelle est aménagée une collerette 55 de claquage.The bottle 5 has a generally cylindrical shape or parallelepipedic whose walls 53 are relatively rigid; one face of the bottle 5 is provided with a bellows 51 whose maneuverable wall 54 has a closable passage 52, for example a small cylindrical opening; the bellows 51 which tightly connects the wall 54 to the walls 53 obviously has the flexibility necessary for the operation of the bellows; the bottle 5 is provided with a neck 57 which ends in a face 56 of annular support under which a flange 55 is fitted.

La collerette 55 de claquage du flacon 5 et l'anneau 45 de claquage de l'activateur 4 sont agencés pour s'encliqueter l'un sur l'autre en emprisonnant de manière étanche, entre la face 56 d'appui annulaire du flacon 5 et la face 46 d'appui annulaire de l'activateur 4, les deux collerettes 21, 31, annulaires respectivement de la poche 2 souple et du dôme 3.The flange 55 for snapping on the bottle 5 and the snap ring 45 for activating the activator 4 are arranged to snap onto each other while sealingly trapped between the face 56 of the annular support of the bottle 5 and the face 46 of the annular support of the activator 4, the two annular flanges 21, 31, respectively of the flexible bag 2 and the dome 3.

Le montage de l'ensemble distributeur s'effectue comme suit : introduction de la poche 2 souple dans le flacon 5 à travers son goulot 57 en appliquant la collerette 21 annulaire de la poche 2 souple sur la face 56 d'appui annulaire du flacon 5, remplissage de la poche 2 souple avec le produit à distribuer, positionnement du dôme sur la collerette 21 annulaire de la poche 2 souple, et enfin encliquetage du corps 41 de l'activateur 4 pour obtenir l'ensemble distributeur terminé. La poignée 43 de l'activateur 4 est clairement agencée pour pouvoir se rabattre en pivotant autour de la charnière 48 et ainsi venir entourer le flacon 5, le bossage 44 étant positionné pour se trouver en vis-à-vis du passage obturable 52.The assembly of the dispenser assembly is carried out as follows: introduction of the flexible bag 2 into the bottle 5 through its neck 57 by applying the annular flange 21 of the flexible bag 2 to the face 56 of the annular support of the bottle 5 , filling the flexible pouch 2 with the product to be dispensed, positioning the dome on the annular flange 21 of the flexible pouch 2, and finally snap-fastening of the body 41 of the activator 4 to obtain the finished dispenser assembly. The handle 43 of the activator 4 is clearly arranged so that it can be folded down by pivoting around the hinge 48 and thus come to surround the bottle 5, the boss 44 being positioned so as to be opposite the closable passage 52.

La figure 2 est une vue extérieure de l'ensemble distributeur ainsi obtenu. On y voit le flacon 5 partiellement caché par la poignée 43 articulée sur le corps 41 au moyen de la charnière souple 48 ; la capsule 42, articulée autour de la charnière souple 49 est représentée ici en position fermée.Figure 2 is an exterior view of the dispenser assembly thus obtained. We see the bottle 5 partially hidden by the handle 43 articulated on the body 41 by means of the flexible hinge 48; the capsule 42, articulated around the flexible hinge 49 is shown here in the closed position.

La figure 3 est une vue en coupe de l'ensemble distributeur de la figure 2 mais cette fois-ci avec la capsule 42 ayant pivoté de 180° autour de la charnière 49 pour se trouver en position ouverte de sorte que l'ensemble distributeur est prêt à l'usage. On voit sur cette figure le produit 6 à distribuer contenu dans la poche souple 2 laquelle est fermée par le dôme 3 ; le corps 41 est en position encliquetée sur le flacon 5 et la poignée 43 qui peut pivoter autour de l'articulation 48, est en position prête à l'usage.Figure 3 is a sectional view of the dispenser assembly of Figure 2 but this time with the capsule 42 having pivoted 180 ° around the hinge 49 to be in the open position so that the dispenser assembly is ready to use. We see in this figure the product 6 to distribute contained in the flexible bag 2 which is closed by the dome 3; the body 41 is in the latched position on the bottle 5 and the handle 43 which can pivot around the joint 48, is in the ready-to-use position.

Le soufflet 51, constitué d'un matériau élastique, est ici représenté dans sa position de repos. On connaît le principe général de fonctionnement d'un soufflet ; ici il va être utilisé pour comprimer l'air situé entre le flacon 5 et la poche 2. Sur le détail de la figure 3a est représenté le passage 52 obturable qui constitue l'entrée d'air du soufflet aménagée dans la paroi 54 du flacon 5 ; en vis-à-vis de ce passage obturable est prévu, sur la poignée 43, l'élément en relief 44 destiné à obturer l'entrée d'air du soufflet ; ici l'élément en relief 44 est un bossage annulaire en forme de couronne centrée sur le passage.The bellows 51, made of an elastic material, is here shown in its rest position. We know the general principle of operation of a bellows; here it will be used to compress the air located between the bottle 5 and the bag 2. In the detail of FIG. 3 a is shown the closable passage 52 which constitutes the air inlet of the bellows arranged in the wall 54 of the bottle 5; vis-à-vis this closable passage is provided on the handle 43, the relief element 44 intended to close the air inlet of the bellows; here the relief element 44 is an annular boss in the form of a crown centered on the passage.

La figure 4, avec le détail en figure 4a, explicite le mode opératoire de l'ensemble distributeur.FIG. 4, with the detail in FIG. 4 a , explains the operating mode of the dispenser assembly.

Lorsqu'une force P est exercée pour rapprocher la poignée 43 du flacon 5, la couronne 44 de la poignée 43 vient d'abord coiffer le passage 52 de la paroi 54 de sorte que l'air qui se trouve entre le flacon 5 et la poche 2 souple est emprisonné. La pression de l'air ainsi emprisonné augmente donc sous l'action du soufflet 51 comprimé par la force P agissant sur la poignée 43. Cette augmentation de pression agit sur le flacon 2 souple de sorte que le produit 6 est soumis à une pression suffisante pour le faire sortir par la fente du dôme 3.When a force P is exerted to bring the handle 43 closer to the bottle 5, the crown 44 of the handle 43 first covers the passage 52 of the wall 54 so that the air which is between the bottle 5 and the pocket 2 flexible is trapped. The pressure of the air thus trapped therefore increases under the action of the bellows 51 compressed by the force P acting on the handle 43. This increase in pressure acts on the flexible bottle 2 so that the product 6 is subjected to a pressure sufficient to bring it out through the dome slot 3.

Lorsque la force P cesse, la poignée 43 s'écarte, de sorte que l'air peut à nouveau pénétrer par le passage 52, entre le flacon 5 et la poche 2, au fur et à mesure que le soufflet 51 reprend sa position initiale du fait de son élasticité. Le dôme 3 étant pourvu d'une fente apte à délivrer le produit 6 sans reprise d'air, la poche 2 souple conserve la forme et le volume qu'elle avait atteints en fin de manoeuvre.When the force P ceases, the handle 43 moves apart, so that air can again enter through the passage 52, between the bottle 5 and the bag 2, as the bellows 51 returns to its initial position because of its elasticity. The dome 3 being provided with a slot capable of delivering the product 6 without air intake, the flexible pocket 2 retains the shape and the volume it had reached at the end of the maneuver.

Ce mode opératoire est clairement répétitif de sorte que le volume de la poche 2 souple est progressivement réduit en fonction de la quantité de produit délivrée lors de chaque manoeuvre.This operating mode is clearly repetitive so that the volume of the flexible bag 2 is gradually reduced as a function of the quantity of product delivered during each maneuver.
