Definitions

  • the present invention relates to a distribution assembly for one or more fluid product (s) in the form of a liquid or cream (or paste) of varying thickness. This set makes it possible in particular to distribute cosmetic or pharmaceutical products.
  • Numerous dispensing assemblies comprising a container containing the product to be dispensed, on which a dispensing head is fixed removably or not.
  • This dispensing head includes a device allowing the user to activate the dispensing, and at least one dispensing channel communicating, on the one hand, with the container containing the product to be dispensed, and, on the other hand, with the 'outside.
  • the container when there are several products to be distributed, can comprise several parts, either because it consists of several independent containers, or because it consists of a single container divided by internal partitions into several compartments, each of the containers or compartments being connected to a channel of the same dispensing head.
  • the dispensing head may also contain a compartment for a product different from that contained in the container, this compartment being connected to the distribution channel for the product contained in the container or to a different channel.
  • the closure system consists of the edge of the sleeve of elastic material which rests on the two opposite faces of the end of said planar partition; this edge is in contact with these two faces of the partition when there is no distribution, deviates from these faces when there is distribution of the product to be distributed and returns by elasticity in contact with these faces when ceases the distribution.
  • the object of the invention is to block systems which are integral with the dispensing head.
  • the present invention has for first object a distribution assembly of at least one fluid product, assembly which comprises a container and a distribution head containing at least one distribution channel of the product (s) to be distributed, a distribution system closure being located at the terminal part, opening on the outside of (or each) distribution channel, said system being formed by at least one obturator which is part of a piece of elastically deformable material of the distribution head and by at least one seat, which is part of another part of the dispensing head, the shutter (s) is in contact with their associated seat when there is no dispensing, s '' spreading from said seat by elastic deformation under the pressure of the product to be dispensed and returning by elasticity in contact with said seat when dispensing ceases, in which the dispensing head comprises a device for blocking the closure system ure, characterized in that the blocking device is constituted by a flap secured to the dispensing head sliding on a part secured to the dispensing head.
  • the present invention has for second object an assembly in which the blocking device is constituted by a movable lug arranged on a stirrup which can pivot on two coaxial axes carried by the dispensing head.
  • the (or each) shutter (s) is subjected to the action of a constraint member tending to keep it (or them) applied (s) on the seat with which it (s) cooperates (s) to seal the closing contact.
  • the seal mentioned in the definition below is only guaranteed for imperfections near realization. According to the invention, it must be sufficient to prevent practically any aspiration of air through the closure system after the end of the dispensing of the product, whatever the viscosity of the product to be dispensed.
  • the tightness being somewhat a function of the contact area between the shutter and the seat, the invention provides for choosing a contact area having a sufficient dimension for the tightness to be ensured.
  • This blocking device can be a device which is moved to effect the first distribution and which can be replaced later.
  • the blocking member can be replaced after one or more distribution (s) to ensure sealing during transport and avoid accidental opening of the closure system.
  • the locking devices according to the invention have an action only on the closing system proper.
  • the locking device constituted by a sliding shutter blocks the flexibility of the lip of the elastic blade of the closure system.
  • the system constituted by a lug blocks the elasticity of the shutter in the closure system, by snap-fastening at the level of the dispensing orifice.
  • the stirrup can also, after disengaging the lug, serve as a lever to exert the dispensing pressure.
  • the assembly 1 is constituted by a dispensing head 3 which comprises a single valve constituted by a closure system with elastic lip, the head being fixed on a flexible tube 2.
  • the tube 2 is provided with a neck 4 comprising, on the tube side, a part 5 of larger diameter and on the dispensing head side, a coaxial part 6 of smaller diameter.
  • Part 5 is provided with two circular beads 5 a and 5 b of identical outside diameters.
  • the part 6 of smaller diameter has at least one rectangular notch 7 on its upper edge.
  • the dispensing head 3 is a side dispensing head. It has a generally cylindrical shape provided with a radial lateral extension forming a spout 3 a ; the closure system F is located at the outer end of this spout 3 a .
  • Said head 3 comprises a part 8 comprising the seat situated in a plane perpendicular to the longitudinal axis X - X of the assembly 1, covering the entire outer surface of the dispensing head farthest from the tube 2, that is to say that is to say the upper surface according to FIG. 1.
  • This part 8 comprising the seat has the shape of a disc provided with a radial spout 8 a of rectangular shape projecting towards the outside.
  • the part 8 comprising the seat is also provided with a cylindrical cavity 8 b into which is inserted the narrow part 6 of the neck 4 of the tube 2.
  • a groove 8 c ends in the vicinity of the outer edge of the spout 8 a of the part 8 comprising the seat by a slope 8 d inclined towards the outside and towards the tube 2.
  • the internal face (upper in FIG. 1) of the external edge of the spout forms the seat 8 e .
  • the seat 8 e is located in a plane perpendicular to the longitudinal axis XX of the distributor assembly and has the shape of a rectangle.
  • a blade of elastic material 9 comprising the lip of the closure system is placed in contact with the internal face (lower face in FIG. 1) of the part 8 comprising the seat 8 e and rests on a support 10.
  • the blade of elastic material 9 covers the entire internal surface of the part 8 comprising the seat, that is to say that it has the shape of a disc provided with a spout the end of which is cut at a bevel and which is located at right the nozzle 8a of the part 8 comprising the seat.
  • the beveled end of the spout is inclined towards the part 8 comprising the seat and its edge forms the lip 9 a of the closure system.
  • the closure system F consists of the seat formed by the surface 8 e of the spout 8 a and by the lip 9 a of the blade 9, a lip formed by the edge of the outside at a bevel of the spout.
  • the support 10 acts as a constraint member. It has a rigid flat wall, parallel to the part 8 comprising the seat and the blade 9, having the shape of a disc 11 provided with a rectangular spout 11 a disposed opposite the spout 8 a of the part comprising the seat 8 and the spout 9 a of the blade 9.
  • the bevel of the beak of the blade 9 forming the lip 9 has protruded beyond the beak 11 a of the rigid wall.
  • an axial and circular opening 11 b bordered by a cylindrical skirt 11 c turned towards the tube 2. Said skirt 11 c surrounds the narrowest part 6 of the neck 4 of the tube 2.

Abstract

A dispenser for a fluid substance, esp. used in cosmetics or pharmaceuticals, consists of a cap (1) which fits onto the container (2) and made with at least one outlet channel (8). The/each outlet channel has a system which closes its outlet, made in the form of a shutter (9a) which is able to deform elastically and interact with a seat (8e). The deforming shutter and seat form a self-closing valve which is opened by the pressure of the fluid passing through it but closes once the pressure stops. The shutter is pressed towards the seat by a support which limits its deformation. The pressure which expels the fluid from the container can be of various types, e.g. a pump piston or flexible bulb.

Description

La présente invention concerne un ensemble de distribution d'un ou plusieurs produit(s) fluide(s) sous forme de liquide ou de crème (ou pâte) plus ou moins épaisse. Cet ensemble permet notamment de distribuer des produits cosmétiques ou pharmaceutiques.The present invention relates to a distribution assembly for one or more fluid product (s) in the form of a liquid or cream (or paste) of varying thickness. This set makes it possible in particular to distribute cosmetic or pharmaceutical products.

On connaît de nombreux ensembles de distribution comportant un récipient contenant le produit à distribuer, sur lequel, on fixe de façon amovible ou non, une tête de distribution. Cette tête de distribution comporte un dispositif permettant à l'utilisateur d'actionner la distribution, et au moins un canal de distribution communiquant, d'une part, avec le récipient contenant le produit à distribuer, et, d'autre part, avec l'extérieur.Numerous dispensing assemblies are known comprising a container containing the product to be dispensed, on which a dispensing head is fixed removably or not. This dispensing head includes a device allowing the user to activate the dispensing, and at least one dispensing channel communicating, on the one hand, with the container containing the product to be dispensed, and, on the other hand, with the 'outside.

De façon connue, lorsqu'il y a plusieurs produits à distribuer, le récipient peut comporter plusieurs parties, soit qu'il soit constitué de plusieurs conteneurs indépendants, soit qu'il soit constitué d'un conteneur unique divisé par des cloisons internes en plusieurs compartiments, chacun des conteneurs ou des compartiments étant relié à un canal de la même tête de distribution. La tête de distribution peut également contenir un compartiment pour un produit différent de celui contenu dans le récipient, ce compartiment étant relié au canal de distribution du produit contenu dans le récipient ou à un canal différent.In a known manner, when there are several products to be distributed, the container can comprise several parts, either because it consists of several independent containers, or because it consists of a single container divided by internal partitions into several compartments, each of the containers or compartments being connected to a channel of the same dispensing head. The dispensing head may also contain a compartment for a product different from that contained in the container, this compartment being connected to the distribution channel for the product contained in the container or to a different channel.

Il est connu, qu'après la distribution du produit, une partie de celui-ci reste dans le canal de distribution. Cette partie du produit est en contact avec l'air lors de la reprise d'air de la tête de distribution et, éventuellement, au cours du stockage. Le produit peut donc être dégradé par oxydation ou souillé par les impuretés et les micro-organismes de l'air et, par conséquent, lors d'une distribution ultérieure, le produit distribué pourra avoir perdu ses qualités et même être devenu nocif.It is known that after the distribution of the product, part of it remains in the distribution channel. This part of the product is in contact with air during the air intake from the dispensing head and, possibly, during storage. The product can therefore be degraded by oxidation or contaminated by impurities and microorganisms in the air and, consequently, during a subsequent distribution, the distributed product may have lost its qualities and even become harmful.

Dans US-A-4 099 651, on a proposé de résoudre ce problème par un système de fermeture ne s'ouvrant que sous la poussée du produit à distribuer. Ce brevet décrit une tête de distribution comportant un élément tubulaire fixé sur l'embout d'un tube souple ; l'élément tubulaire contient, sur au moins une partie de sa longueur, une cloison plane qui dépasse de l'élément tubulaire : deux canaux de sortie du produit sont ainsi définis. Un manchon en matériau élastique est enfilé sur l'élément tubulaire et sur la partie de la cloison plane qui en dépasse. Le système de fermeture est constitué par le bord du manchon en matériau élastique qui repose sur les deux faces opposées de l'extrémité de ladite cloison plane ; ce bord est en contact avec ces deux faces de la cloison lorsqu'il n'y a pas de distribution, s'écarte de ces faces lorsqu'il y a distribution du produit à distribuer et revient par élasticité en contact avec ces faces lorsque cesse la distribution.In US-A-4,099,651, it has been proposed to solve this problem by a closure system which opens only under the pressure of the product to be dispensed. This patent describes a dispensing head comprising a tubular element fixed to the end piece of a flexible tube; the tubular element contains, over at least part of its length, a flat partition which protrudes from the tubular element: two product outlet channels are thus defined. A sleeve of elastic material is fitted over the tubular element and over the part of the planar partition which projects beyond it. The closure system consists of the edge of the sleeve of elastic material which rests on the two opposite faces of the end of said planar partition; this edge is in contact with these two faces of the partition when there is no distribution, deviates from these faces when there is distribution of the product to be distributed and returns by elasticity in contact with these faces when ceases the distribution.

Cependant, dans un tel système de fermeture, le contact entre le bord du manchon et la face de la cloison n'est assuré que par l'élasticité de la zone de bord du manchon et il en résulte fréquemment une étanchéité au repos très insuffisante, quelle que soit la surface de contact entre le bord du manchon et chacune des faces de la cloison, en particulier lorsque le produit distribué est visqueux.However, in such a closure system, the contact between the edge of the sleeve and the face of the partition is only ensured by the elasticity of the edge area of the sleeve and this frequently results in a very insufficient seal at rest, whatever the contact surface between the edge of the sleeve and each of the faces of the partition, in particular when the product dispensed is viscous.

Dans US-A-4 099 651 on a proposé de protéger la tête de distribution lors du stockage à l'aide d'un capuchon comportant des éléments internes venant bloquer la fermeture. Cependant, ces capuchons n'étant pas solidaires de la tête de distribution sont facilement égarés. Il n'y a alors plus aucun moyen de blocage de la fermeture.In US-A-4,099,651, it has been proposed to protect the dispensing head during storage with the aid of a cap comprising internal elements which block the closure. However, these caps not being integral with the dispensing head are easily lost. There is then no longer any means of blocking the closure.

L'invention a pour but des systèmes de blocage qui sont solidaires de la tête de distribution.The object of the invention is to block systems which are integral with the dispensing head.

La présente invention a pour premier objet un ensemble de distribution d'au moins un produit fluide, ensemble qui comporte un récipient et une tête de distribution contenant au moins un canal de distribution du (des) produit(s) à distribuer, un système de fermeture étant situé à la partie terminale, s'ouvrant sur l'extérieur du (ou de chaque) canal de distribution, ledit système étant formé par au moins un obturateur qui fait partie d'une pièce en matériau élastiquement déformable de la tête de distribution et par au moins un siège, qui fait partie d'une autre pièce de la tête de distribution, l'(ou les) obturateur(s) est en contact avec leur siège associé lorsqu'il n'y a pas de distribution, s'écartant dudit siège par déformation élastique sous la pression du produit à distribuer et revenant par élasticité en contact avec ledit siège lorsque cesse la distribution, dans lequel la tête de distribution comporte un dispositif de blocage du système de fermeture, caractérisé par le fait que le dispositif de blocage est constitué par un volet solidaire de la tête de distribution coulissant sur une pièce solidaire de la tête de distribution.The present invention has for first object a distribution assembly of at least one fluid product, assembly which comprises a container and a distribution head containing at least one distribution channel of the product (s) to be distributed, a distribution system closure being located at the terminal part, opening on the outside of (or each) distribution channel, said system being formed by at least one obturator which is part of a piece of elastically deformable material of the distribution head and by at least one seat, which is part of another part of the dispensing head, the shutter (s) is in contact with their associated seat when there is no dispensing, s '' spreading from said seat by elastic deformation under the pressure of the product to be dispensed and returning by elasticity in contact with said seat when dispensing ceases, in which the dispensing head comprises a device for blocking the closure system ure, characterized in that the blocking device is constituted by a flap secured to the dispensing head sliding on a part secured to the dispensing head.

La présente invention a pour second objet un ensemble dans lequel le dispositif de blocage est constitué par un ergot mobile disposé sur un étrier qui peut pivoter sur deux axes coaxiaux portés par la tête de distribution.The present invention has for second object an assembly in which the blocking device is constituted by a movable lug arranged on a stirrup which can pivot on two coaxial axes carried by the dispensing head.

Avantageusement, le (ou chacun des) obturateur(s) est soumis à l'action d'un organe de contrainte ayant tendance à le (ou les) maintenir appliqué(s) sur le siège avec lequel il(s) coopère(nt) pour assurer l'étanchéité du contact de fermeture.Advantageously, the (or each) shutter (s) is subjected to the action of a constraint member tending to keep it (or them) applied (s) on the seat with which it (s) cooperates (s) to seal the closing contact.

Il est entendu que l'étanchéité mentionnée dans la définition ci-dessous n'est assurée qu'aux imperfections de réalisation près. Selon l'invention elle doit être suffisante pour empêcher pratiquement toute aspiration d'air à travers le système de fermeture après la fin de la distribution du produit, quelle que soit la viscosité du produit à distribuer. L'étanchéité étant quelque peu fonction de la zone de contact entre l'obturateur et le siège, l'invention prévoit de choisir une zone de contact ayant une dimension suffisante pour que l'étanchéité soit assurée.It is understood that the seal mentioned in the definition below is only guaranteed for imperfections near realization. According to the invention, it must be sufficient to prevent practically any aspiration of air through the closure system after the end of the dispensing of the product, whatever the viscosity of the product to be dispensed. The tightness being somewhat a function of the contact area between the shutter and the seat, the invention provides for choosing a contact area having a sufficient dimension for the tightness to be ensured.

Ce dispositif de blocage peut être un dispositif que l'on déplace pour effectuer la première distribution et que l'on peut remettre en place ultérieurement.This blocking device can be a device which is moved to effect the first distribution and which can be replaced later.

En effet, il est avantageux que l'organe de blocage puisse être replacé après une ou plusieurs distribution(s) pour assurer l'étanchéité lors du transport et éviter une ouverture accidentelle du système de fermeture. Les dispositifs de blocage selon l'invention n'ont d'action que sur le système de fermeture proprement dit. Le dispositif de blocage constitué par un volet coulissant vient bloquer la flexibilité de la lèvre de la lame élastique du système de fermeture. Le système constitué par un ergot vient bloquer l'élasticité de l'obturateur dans le système de fermeture, par encliquetage au niveau de l'orifice de distribution. De préférence, l'étrier peut également, après désencliquetage de l'ergot, servir de levier pour exercer la pression de distribution.Indeed, it is advantageous that the blocking member can be replaced after one or more distribution (s) to ensure sealing during transport and avoid accidental opening of the closure system. The locking devices according to the invention have an action only on the closing system proper. The locking device constituted by a sliding shutter blocks the flexibility of the lip of the elastic blade of the closure system. The system constituted by a lug blocks the elasticity of the shutter in the closure system, by snap-fastening at the level of the dispensing orifice. Preferably, the stirrup can also, after disengaging the lug, serve as a lever to exert the dispensing pressure.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire ci-après, à titre purement illustratif et non limitatif, plusieurs modes de réalisation représentés sur le dessin annexé.To better understand the object of the invention, we will describe below, purely by way of illustration and not limitation, several embodiments shown in the accompanying drawing.

  • Figures 5 and 6, finally, show in perspective and in axial section a head similar to that of Figure 2 having a particular locking system.

Sur les figures 1 et 2, l'ensemble 1 est constitué par une tête de distribution 3 qui comporte une seule valve constituée par un système de fermeture à lèvre élastique, la tête étant fixée sur un tube souple 2.In FIGS. 1 and 2, the assembly 1 is constituted by a dispensing head 3 which comprises a single valve constituted by a closure system with elastic lip, the head being fixed on a flexible tube 2.

Le tube 2 est muni d'un goulot 4 comportant, côté tube, une partie 5 de plus grand diamètre et coté tête de distribution, une partie 6 coaxiale de plus petit diamètre. La partie 5 est munie de deux bourrelets 5a et 5b circulaires de diamètres extérieurs identiques.The tube 2 is provided with a neck 4 comprising, on the tube side, a part 5 of larger diameter and on the dispensing head side, a coaxial part 6 of smaller diameter. Part 5 is provided with two circular beads 5 a and 5 b of identical outside diameters.

La partie 6 de plus petit diamètre présente au moins une échancrure rectangulaire 7 sur son bord supérieur.The part 6 of smaller diameter has at least one rectangular notch 7 on its upper edge.

La tête de distribution 3 est une tête à distribution latérale. Elle a une forme générale cylindrique munie d'une extension latérale radiale formant bec 3a ; le système de fermeture F est situé à l'extrémité extérieure de ce bec 3a.The dispensing head 3 is a side dispensing head. It has a generally cylindrical shape provided with a radial lateral extension forming a spout 3 a ; the closure system F is located at the outer end of this spout 3 a .

Ladite tête 3 comporte une pièce 8 comportant le siège située dans un plan perpendiculaire à l'axe longitudinal X - X de l'ensemble 1, couvrant toute la surface extérieure de la tête de distribution la plus éloignée du tube 2, c'est-à-dire la surface supérieure selon la figure 1. Cette pièce 8 comportant le siège a la forme d'un disque muni d'un bec radial 8a de forme rectangulaire se projetant vers l'extérieur. La pièce 8 comportant le siège est également munie d'une cavité cylindrique 8b dans laquelle vient s'insérer la partie étroite 6 du goulot 4 du tube 2. Une rainure 8c se termine au voisinage du bord extérieur du bec 8a de la pièce 8 comportant le siège par une pente 8d inclinée vers l'extérieur et en direction du tube 2. La face interne (supérieure sur la figure 1) du bord extérieur du bec forme le siège 8e. Le siège 8e est situé dans un plan perpendiculaire à l'axe longitudinal X-X de l'ensemble distributeur et a la forme d'un rectangle.Said head 3 comprises a part 8 comprising the seat situated in a plane perpendicular to the longitudinal axis X - X of the assembly 1, covering the entire outer surface of the dispensing head farthest from the tube 2, that is to say that is to say the upper surface according to FIG. 1. This part 8 comprising the seat has the shape of a disc provided with a radial spout 8 a of rectangular shape projecting towards the outside. The part 8 comprising the seat is also provided with a cylindrical cavity 8 b into which is inserted the narrow part 6 of the neck 4 of the tube 2. A groove 8 c ends in the vicinity of the outer edge of the spout 8 a of the part 8 comprising the seat by a slope 8 d inclined towards the outside and towards the tube 2. The internal face (upper in FIG. 1) of the external edge of the spout forms the seat 8 e . The seat 8 e is located in a plane perpendicular to the longitudinal axis XX of the distributor assembly and has the shape of a rectangle.

Une lame en matériau élastique 9 comportant la lèvre du système de fermeture est placée en contact avec la face interne (face inférieure sur la figure 1) de la pièce 8 comportant le siège 8e et repose sur un support 10. La lame de matériau élastique 9 recouvre toute la surface interne de la pièce 8 comportant le siège, c'est-à-dire qu'elle a la forme d'un disque muni d'un bec dont l'extrémité est taillée en biseau et qui est situé au droit du bec 8a de la pièce 8 comportant le siège. L'extrémité en biseau du bec est inclinée vers la pièce 8 comportant le siège et son bord forme la lèvre 9a du système de fermeture.A blade of elastic material 9 comprising the lip of the closure system is placed in contact with the internal face (lower face in FIG. 1) of the part 8 comprising the seat 8 e and rests on a support 10. The blade of elastic material 9 covers the entire internal surface of the part 8 comprising the seat, that is to say that it has the shape of a disc provided with a spout the end of which is cut at a bevel and which is located at right the nozzle 8a of the part 8 comprising the seat. The beveled end of the spout is inclined towards the part 8 comprising the seat and its edge forms the lip 9 a of the closure system.

En résumé, le système de fermeture F est constitué par le siège formé par la surface 8e du bec 8a et par la lèvre 9a de la lame 9, lèvre formée par le bord de l'extérieur en biseau du bec.In summary, the closure system F consists of the seat formed by the surface 8 e of the spout 8 a and by the lip 9 a of the blade 9, a lip formed by the edge of the outside at a bevel of the spout.

Le support 10 fait office d'organe de contrainte. Il comporte une paroi plane rigide, parallèle à la pièce 8 comportant le siège et à la lame 9, ayant la forme d'un disque 11 muni d'un bec 11a rectangulaire disposé au vis-à-vis du bec 8a de la pièce comportant le siège 8 et du bec 9a de la lame 9. Le biseau du bec de la lame 9 formant la lèvre 9a fait saillie au-delà du bec 11a de la paroi rigide. Dans la paroi plane 11 est ménagée une ouverture axiale et circulaire 11b bordée par une jupe 11c cylindrique tournée en direction du tube 2. Ladite jupe 11c entoure la partie la plus étroite 6 du goulot 4 du tube 2.The support 10 acts as a constraint member. It has a rigid flat wall, parallel to the part 8 comprising the seat and the blade 9, having the shape of a disc 11 provided with a rectangular spout 11 a disposed opposite the spout 8 a of the part comprising the seat 8 and the spout 9 a of the blade 9. The bevel of the beak of the blade 9 forming the lip 9 has protruded beyond the beak 11 a of the rigid wall. In the planar wall 11 is formed an axial and circular opening 11 b bordered by a cylindrical skirt 11 c turned towards the tube 2. Said skirt 11 c surrounds the narrowest part 6 of the neck 4 of the tube 2.

Le support 10 comporte également une jupe périphérique 12 qui est fixée à la périphérie de la pièce 8 comportant le siège 8e par un système de nervure et rainure, sauf au niveau du bord du bec 8a de la pièce comportant le siège 8e. Cette jupe 12 comporte une échancrure au vis-à-vis du bec 11a du disque rigide 11.The support 10 also includes a peripheral skirt 12 which is fixed to the periphery of the part 8 comprising the seat 8 e by a rib and groove system, except at the edge of the spout 8 a of the part comprising the seat 8 e . This skirt 12 has a notch opposite the spout 11 a of the rigid disc 11.

La jupe 12 est munie sur sa face interne d'un bourrelet circulaire 12a qui vient se placer par claquage sous le bourrelet 5a de la partie 5 de plus grand diamètre du goulot 4 du tube 2.The skirt 12 is provided on its internal face with a circular bead 12 a which is placed by snapping under the bead 5 a of the part 5 of larger diameter of the neck 4 of the tube 2.

L'appareil fonctionne de la façon suivante : quand l'utilisateur désire distribuer le produit contenu dans le tube 2, il fait tourner la tête de distribution 3 jusqu'à ce que l'échancrure 7 du goulot 4 vienne en face de la rainure 8c du siège 8. Puis il appuie sur le tube 2, ce qui fait passer le produit à travers le premier conduit formé par le goulot 4 dans le second conduit perpendiculaire délimité par la lame 9 et la rainure 8c de la pièce 8 comportant le siège.The device operates as follows: when the user wishes to dispense the product contained in the tube 2, he rotates the dispensing head 3 until the notch 7 of the neck 4 comes in front of the groove 8 c of the seat 8. Then he presses the tube 2, which passes the product through the first conduit formed by the neck 4 in the second perpendicular conduit delimited by the blade 9 and the groove 8 c of the part 8 comprising the seat.

Lorsque le produit arrive au niveau de la zone de fermeture F, la lèvre 9a formée par le bord s'écarte par flexion de la surface 8e du bec 8a, de la pièce 8 comportant le siège, perpendiculairement à la direction de poussée du produit et le produit peut sortir comme illustré sur la figure 2. Le support 10 qui maintient la lame limite le déplacement de la lèvre 9a lors de l'ouverture du système de fermeture. Dès que l'utilisateur cesse d'appuyer sur le tube 2, il n'y a plus de poussée du produit à distribuer au niveau du système de fermeture F et la lèvre 9a revient, par élasticité, en contact avec le siège 8e, dans la zone de fermeture F. Le support 10 exerce alors sur la lame 9 une certaine contrainte qui applique la lèvre 9a contre le siège 8e et assure l'étanchéité désirée convenable. L'air ne peut plus pénétrer dans le tube 2 et, par conséquent, le produit ne peut pas être souillé par des impuretés ou micro-organismes, ni oxydé.When the product arrives at the level of the closing zone F, the lip 9 a formed by the edge deviates by bending from the surface 8 e of the spout 8 a , from the part 8 comprising the seat, perpendicular to the direction of thrust of the product and the product can exit as illustrated in FIG. 2. The support 10 which holds the blade limits the movement of the lip 9 a during opening of the closing system. As soon as the user stops pressing on the tube 2, there is no more thrust of the product to be dispensed at the closing system F and the lip 9 a returns, by elasticity, in contact with the seat 8 e , in the closed zone F. The support 10 then exerts on the blade 9 a certain constraint which applies the lip 9 a against the seat 8 e and ensures the desired desired tightness. The air can no longer enter the tube 2 and, therefore, the product cannot be contaminated by impurities or microorganisms, nor oxidized.

La lèvre 1705a de la lame peut être maintenue au cours du stockage à l'aide d'un dispositif de blocage, constitué par un étrier 1707 en matériau semi-rigide fixe pivotant par encliquetage de ses deux branches latérales 1771 sur deux axes 1772 et muni sur la barre transversale d'un ergot 1773 disposé au niveau du système de fermeture F. En position de stockage, l'étrier 1707 est dans la position représentée sur les figures 3a et 3b. La figure 3c représente, en traits mixtes, l'étrier 1707 en cours de déblocage et, en trait continu, l'étrier en position de repos après déblocage.FIG. 3 a to 3 c schematically represent a dispensing head 1703 with lateral spout 1703 a comprising a blade 1705 with a beveled end 1705 a resting on a part comprising the seat and held by a cover 1706 forming a constraint member. The lip 1705 a of the blade can be maintained during storage by means of a locking device, constituted by a stirrup 1707 of fixed semi-rigid material pivoting by snap-fastening of its two lateral branches 1771 on two axes 1772 and provided on the crossbar with a lug 1773 arranged at the closing system F. In the storage position, the stirrup 1707 is in the position shown in FIGS. 3 a and 3 b . FIG. 3 c shows , in phantom, the stirrup 1707 being released and, in solid line, the stirrup in the rest position after unlocking.

Les figures 4a à 4c représentent schématiquement une tête de distribution 1803, à bec latéral, formant pompe comportant un bouton-poussoir et un étrier 1807 de blocage de la lame 1805 du sytème de fermeture F. L'étrier 1807 est fixé pivotant en un point voisin du milieu de ses bras 1871, sur deux axes 1872 portés par le bouton-poussoir 1808. La barre transversale de l'étrier est munie d'un élargissement 1879 dont un bord porte l'ergot 1873 et qui forme une surface légèrement incurvée formant un angle avec les bras de l'étrier. L'étrier 1807 oscille entre une position représentée sur la figure 4a où il bloque le dispositif de fermeture à l'aide de l'ergot 1873 et, par l'intermédiaire de la position représentée sur la figure 4b, une position représentée sur la figure 4c, où l'étrier 1807 repose par une partie de sa surface élargie 1879, sur la surface supérieure du bouton-poussoir et est bloqué par un plot 1874 porté par une patte fixe solidaire du récipient 1809. L'étrier peut être alors utilisé comme un levier pour appuyer sur le bouton-poussoir 1808. En appuyant sur la face incurvée de l'élargissement 1873, l'utilisateur obtient une démultiplication de la force de pression exercée sur le bouton-poussoir 1808.FIGS. 4 a to 4 c schematically represent a dispensing head 1803, with lateral spout, forming a pump comprising a push button and a stirrup 1807 for blocking the blade 1805 of the closing system F. The stirrup 1807 is pivotally fixed in a point near the middle of his arms 1871, on two axes 1872 carried by the push button 1808. The cross bar of the stirrup is provided with an enlargement 1879, one edge of which carries the lug 1873 and which forms a slightly curved forming an angle with the arms of the stirrup. The stirrup 1807 oscillates between a position shown in FIG. 4 a where it blocks the closing device using the lug 1873 and, through the position shown in FIG. 4 b , a position shown on FIG. 4 c , where the stirrup 1807 rests by a part of its enlarged surface 1879, on the upper surface of the push-button and is blocked by a stud 1874 carried by a fixed tab secured to the container 1809. The stirrup can be then used as a lever to press the push button 1808. By pressing the curved face of the enlargement 1873, the user obtains a reduction in the pressure force exerted on the push button 1808.

Les figures 5 et 6 montrent une tête de distribution 1603 à bec latéral comportant une lame 1605 prise en sandwich entre une pièce rigide 1604 comportant le siège et un couvercle 1606 formant organe de contrainte. Sur le couvercle 1606 est ménagée une ouverture 1661 rectangulaire disposée symétriquement par rapport au plan médian de la lame et s'étendant de la limite du biseau 1605a de la lame 1605 diamétralement jusqu'au voisinage du bord du couvercle opposé au bec 1603a de la tête de distribution 1603. Dans cette ouverture peut coulisser selon la double flèche f, une languette 1607 qui modifie, selon sa position, la flexibilité de la lèvre de la lame 1605 de façon à régler la pression du produit nécessaire pour l'ouverture du système de fermeture.Figures 5 and 6 show a dispensing head 1603 with side spout comprising a blade 1605 sandwiched between a rigid part 1604 comprising the seat and a cover 1606 forming a constraint member. On the cover 1606 is formed a rectangular opening 1661 arranged symmetrically with respect to the median plane of the blade and extending from the limit of the bevel 1605 a of the blade 1605 diametrically to the vicinity of the edge of the cover opposite the beak 1603 a the dispensing head 1603. In this opening can slide along the double arrow f , a tongue 1607 which modifies, according to its position, the flexibility of the lip of the blade 1605 so as to adjust the pressure of the product necessary for the opening of the closing system.
