Description

L'invention concerne le domaine des distributeurs pour produits pâteux et plus particulièrement ceux utilisant d'une part un système de compression et d'aspiration commandé par l'écrasement de leur tête souple en matière plastique et d'autre part un piston glissant. Le terme produit pâteux désigne ici tout produit de consistance pâteuse pouvant être distribué au moyen d'un tel dispositif, qu'il soit qualifié de pâte, de gel ou de crème épaisse.The invention relates to the field of dispensers for pasty products and more particularly those using on the one hand a compression and suction system controlled by the crushing of their flexible plastic head and on the other hand a sliding piston. The term pasty product here designates any product of pasty consistency which can be distributed by means of such a device, whether it is described as paste, gel or thick cream.

ETAT DE LA TECHNIQUE CONNUEKNOWN STATE OF THE ART

Le document EP-A-0048421 (US-A-4394939) décrit un distributeur pour produits pâteux dont le corps porte, à sa partie supérieure, une soupape d'aspiration du produit pâteux de la chambre de stockage comprise entre son piston glissant et cette partie supérieure vers la chambre de pompage ou de compression, cette soupape comprenant un siège à fenêtres de passage latérales et une pièce annulaire d'obturation de ces fenêtres, pièce reliée par au moins trois rayons souples à un moyen fixé lui-même à une axe ou à un ergot central du siège sous-jacent. Le dôme de la tête fixée par encliquetage sur le corps est souple et écrasable, permettant de réaliser par écrasement puis relâchement l'explusion du produit pâteux et son aspiration de la chambre de stockage vers la chambre de pompage ou de compression. La soupape d'expulsion du produit vers le conduit et l'orifice de distribution a pour siège l'extrémité de la tubulure surmontant le dôme et comprend un clapet qui est fixé à l'intérieur de l'actionneur. L'assemblage des moyens d'aspiration, de compression et d'expulsion se fait ainsi avec 5 pièces, ou encore 3 pièces en plus du corps de distribution et de l'actionneur. La pièce annulaire d'obturation des fenêtres de passage du produit de la chambre de stockage à la chambre de pompage ou de compression est assez fragile.The document EP-A-0048421 (US-A-4394939) describes a dispenser for pasty products, the body of which carries, at its upper part, a suction valve for the pasty product from the storage chamber between its sliding piston and this upper part towards the pumping or compression chamber, this valve comprising a seat with lateral passage windows and an annular part for closing these windows, part connected by at least three flexible spokes to a means itself fixed to an axis or to a central lug on the underlying seat. The dome of the head fixed by snap-fastening on the body is flexible and can be crushed, making it possible to crush and then release the expulsion of the pasty product and its aspiration from the storage chamber towards the pumping or compression chamber. The valve for expelling the product to the conduit and the dispensing orifice has for seat the end of the tubing surmounting the dome and comprises a valve which is fixed inside the actuator. The assembly of the suction, compression and expulsion means is thus done with 5 parts, or even 3 parts in addition to the distribution body and the actuator. The annular blocking part of the windows for the passage of the product from the storage chamber to the pumping or compression chamber is quite fragile.

b1) l'actionneur comprend d'une part une partie fixe comportant une jupe extérieure portant à sa partie inférieure un moyen de fixation sur le sommet du corps de distributeur, et d'autre part u ne partie centrale inclinable reliée à sa partie fixe et comportant un voile d'appui ainsi qu'un conduit de distribution débouchant dans une cheminée longitudinale qui est portée par le dessous dudit voile d'appui et emboîte de façon étanche la tubulure supérieure d'une coupelle déformable formant avec ledit voile d'appui et avec ledit sommet du corps du distributeur la chambre de compression, la surface de dessous dudit voile au fond de cette cheminée étant plane ou de courbure faible;b1) the actuator comprises on the one hand a fixed part comprising an outer skirt carrying at its lower part a fixing means on the top of the distributor body, and on the other hand a tilting central part connected to its fixed part and comprising a support veil as well as a distribution duct opening into a longitudinal chimney which is carried by the underside of said veil of support and sealingly fits the upper tube of a deformable cup forming with said support veil and with said top of the body of the distributor the compression chamber, the bottom surface of said veil at the bottom of this chimney being flat or low curvature;

b2) le voile déformable délimitant la chambre de compression est compris dans ladite coupelle déformable qui est monobloc et comprend en allant du bas vers le haut: un moyen de fixation étanche sur le sommet du corps de ditributeur, puis ledit voile déformable, puis ladite tubulure supérieure surmontée d'une lèvre supérieure souple qui forme avec ladite surface du fond de ladite cheminée la soupape d'expulsion du produit dans le conduit de distribution.b2) the deformable veil delimiting the compression chamber is included in said deformable cup which is in one piece and comprises, going from bottom to top: a sealed fixing means on the top of the distributor body, then said deformable veil, then said tubing upper surmounted by a flexible upper lip which forms with said surface of the bottom of said chimney the valve for expelling the product into the distribution duct.

Les moyens d'acheminement du produit pâteux de la chambre de stockage au conduit de distribution sont ainsi entièrement nouveaux.The means of conveying the pasty product from the storage chamber to the distribution conduit are thus entirely new.

La coupelle déformable étant un élément distinct, on peut choisir spécialement son matériau constitutif, en même temps que sa géométrie et ses variations d'épaisseur, de façon à obtenir une bonne souplesse et une bonne élasticité de son voile déformable ainsi que de sa lèvre supérieure formant le clapet d'expulsion, en relation avec la nature du produit pâteux distribué. La jupe extérieure fixe de l'actionneur verrouille le bas de cette coupelle déformable et protège son pourtour tandis que l'appui orienté sur la partie centrale inclinable de l'actionneur produit un effet de levier et entraîne de façon particulièrement reproductible l'écrasement de la chambre de compression et l'expulsion du produit pâteux par le fond de la cheminée et le conduit de distribution de cette partie inclinable. Le clapet d'aspiration dont l'ouverture, une fois cet appui relâché, permet la montée du produit pâteux dans la chambre de compression, est solidaire du sommet du corps distributeur. L'assemblage est alors très facile: la coupelle déformable est fixée dans l'actionneur, de façon à réaliser sa fixation étanche à la partie centrale inclinable de l'actionneur, puis l'ensemble est fixé sur le sommet du corps de distributeur, par exemple par encliquetage, ou par tout autre moyen de fixation tel que vissage, collage ou soudage. Pour faciliter la fixation de la coupelle déformable dans l'actionneur, la coupelle comprend de préférence entre son moyen de fixation sur le corps de distributeur et son voile déformable une tubulure inférieure s'emboîtant avec un jeu faible - de préférence moins de 0,6 mm au diamètre - dans la jupe extérieur de l'actionneur. De façon typique, la tubulure supérieure de la coupelle déformable et la cheminée longitudinale de l'actionneur portent des moyens complémentaires de fixation étanche qui coopèrant lors de l'emboîtement de la tubulure par la cheminée, par exemple une nervure circulaire extérieure de la tubulure et une gorge circulaire de l'intérieur de la cheminée.The deformable cup being a separate element, its constituent material can be specially chosen, at the same time as its geometry and its variations in thickness, so as to obtain good flexibility and good elasticity of its deformable veil as well as of its upper lip. forming the expulsion valve, in relation to the nature of the pasty product dispensed. The fixed outer skirt of the actuator locks the bottom of this deformable cup and protects its periphery while the support oriented on the tilting central part of the actuator produces a leverage effect and leads in a particularly reproducible manner to the crushing of the compression chamber and expulsion of the pasty product through the bottom of the chimney and the distribution duct of this tilting part. The suction valve, the opening of which, once this support is released, allows the pasty product to rise in the compression chamber, is integral with the top of the distributor body. The assembly is then very easy: the deformable cup is fixed in the actuator, so as to achieve its tight fixing to the tilting central part of the actuator, then the assembly is fixed to the top of the distributor body, for example by snap-fastening, or by any other fixing means such as screwing, gluing or welding. To facilitate the fixing of the deformable cup in the actuator, the cup preferably comprises between its means of fixing on the distributor body and its deformable veil a lower tube fitting together with a small clearance - preferably less than 0.6 mm in diameter - in the outer skirt of the actuator. Typically, the upper tubing of the deformable cup and the longitudinal chimney of the actuator carry complementary tight fixing means which cooperate during the fitting of the tubing by the chimney, for example an outer circular rib of the tubing and a circular groove inside the chimney.

Le moyen de fixation étanche de la coupelle déformable sur le sommet du corps de distributeur est de façon avantageuse un rebord inférieur circulaire extérieur de cette coupelle, le sommet du corps de distributeur comportant une surface périphérique d'appui de ce rebord, et la jupe extérieure de l'actionneur comportant une surface intérieure d'appui qui, au montage, vient serrer ledit rebord inférieur circulaire de la coupelle sur ladite surface périphérique d'appui.The sealed fastening means of the deformable cup on the top of the distributor body is advantageously a lower circular outer rim of this cup, the top of the distributor body having a peripheral support surface for this rim, and the outer skirt. of the actuator comprising an internal support surface which, when mounted, clamps said circular lower rim of the cup on said peripheral support surface.

La soupape d'aspiration mérite une attention particulière, car son clapet est rendu solidaire du sommet du corps du distributeur par forcement de ses reliefs de retenue au travers de l'orifice central ou à peu près central de ce sommet. Ces reliefs devant être ainsi encliquetables tout en jouant ensuit leur rôle de retenue, consistant à régler et limiter la course d'ouverture du clapet sans qu'il y ait de risque de coincement de ces reliefs dans l' orifice, ce sont de préférence des bossages transversaux ayant un diamètre de cylindre circonscrit supérieur de 1 à 2 mm au diamètre de l'orifice du sommet.The suction valve deserves special attention, because its valve is made integral with the top of the body of the dispenser by forcing its retaining reliefs through the central orifice or approximately central from this top. These reliefs having to be thus snap-on while playing then their retaining role, consisting in regulating and limiting the opening stroke of the valve without there being any risk of jamming these reliefs in the orifice, they are preferably transverse bosses having a circumscribed cylinder diameter 1 to 2 mm greater than the diameter of the aperture of the apex.

De façon à obtenir à la fois un bon guidage du clapet d'aspiration au travers de l'orifice du sommet du corps de distributeur et un écoulement facile du produit pâteux à travers l'espace annulaire d'ouverture de la soupape formée par ce clapet et par le pourtour de l'orifice, il est préférable d'avoir en outre, pour la partie de portion cylindrique du clapet situé en dehors des reliefs de retenue, à la fois des portions de surface cylindriques intermédiaires de diamètre relativement faible et des bossages longitudinaux, c'est-à-dire des portions cylindriques arrondies en relief, ayant un diamètre hors-tout plus grand mais inférieur d'au moins 0,6 mm au diamètre de l'orifice, ces bossages longitudinaux servant alors au guidage du clapet au travers de l'orifice. Le diamètre extérieur du rebord annulaire du voile d'obturation de la soupape d'aspiration est choisi de façon que l'étanchéité soit réalisée en toute position de fermeture de cette soupape compte tenu du jeu de clapet dans l'orifice.So as to obtain both good guidance of the suction valve through the orifice of the top of the distributor body and an easy flow of the pasty product through the annular opening space of the valve formed by this valve and by the periphery of the orifice, it is preferable to have in addition, for the portion of portion cylindrical valve located outside the retaining reliefs, both intermediate cylindrical surface portions of relatively small diameter and longitudinal bosses, that is to say cylindrical portions rounded in relief, having an overall diameter more large but at least 0.6 mm smaller than the diameter of the orifice, these longitudinal bosses then serving to guide the valve through the orifice. The outside diameter of the annular rim of the closure veil of the suction valve is chosen so that the seal is produced in any closed position of this valve, taking account of the valve clearance in the orifice.

De préférence encore, les bossages transversaux de retenue comportant des surfaces supérieures et inférieures inclinées ou arrondies, de façon à obtenir un arrêt en douceux du clapet et à faciliter son encliquetage initial au travers de l'orifice du sommet du corps de distributeur, et le diamètre hors-tout sur les bossages ou nervures longitudinales de guidage est inférieur de 1 à 2 mm au diamètre dudit orifice, cette condition réalisant un bon compromis entre l'exigence de guidage et celle de passage du courant de produit pâteux entre le clapet et l'orifice.More preferably, the transverse retaining bosses having inclined or rounded upper and lower surfaces, so as to obtain a smooth stop of the valve and to facilitate its initial latching through the orifice of the top of the distributor body, and the overall diameter on the bosses or longitudinal guide ribs is 1 to 2 mm less than the diameter of said orifice, this condition achieving a good compromise between the guiding requirement and that of passage of the stream of pasty product between the valve and the 'orifice.

Le clapet est avantageusement obtenue par moulage monobloc avec le sommet du corps du distributeur.The valve is advantageously obtained by one-piece molding with the top of the body of the dispenser.

Dans ce cas, la surface latérale de l'orifice central de ce sommet et le bas de la surface extérieure de la portion cylindrique du clapet portent l'une et l'autre des zones circonférentielles de fracture de hauteurs 0,1 à 0,3 mm se correspondant par emboîtement.In this case, the lateral surface of the central opening of this top and the bottom of the external surface of the cylindrical portion of the valve both have circumferential fracture zones of heights 0.1 to 0.3 mm corresponding by interlocking.

Enfin le voile d'obturation du clapet peut servir de moyen de réglage pour l'écrasement de la chambre de compression, cet écrasement pouvant augmenter lorsque la partie centrale de ce voile est en creux à l'intérieur de la portion cylindrique du clapet.Finally, the valve shutter veil can serve as an adjustment means for crushing the compression chamber, this crushing being able to increase when the central part of this veil is hollow inside the cylindrical portion of the valve.

L'actionneur a de préférence une jupe extérieure échancrée à l'avant et à l'arrière, l'avant désignant l'orientation de l'orifice de distribution du produit pâteux, et une partie centrale inclinable reliée à cette jupe par une patte déformable s'étendant depuis le dessous du conduit de distribution jusqu'au bas de l'échancrure de la jupe. Les échancrures facilitent l'opération de l'actionneur et fixent l'orientation de l'écrasement de la chambre de compression. Cet actionneur peut être rendu inviolable par au moins un pont cassable situé transversalement par rapport au plan de symétrie de l'actionneur et reliant le haut de sa partie centrale inclinable au haut de sa jupe extérieure.The actuator preferably has a scalloped outer skirt at the front and at the rear, the front designating the orientation of the dispensing orifice for the pasty product, and a tilting central part connected to this skirt by a deformable tab extending from below the distribution duct to the bottom of the notch of the skirt. The notches facilitate the operation of the actuator and fix the orientation of the compression of the compression chamber. This actuator can be made inviolable by at least one breakable bridge located transversely to the plane of symmetry of the actuator and connecting the top of its tilting central part to the top of its outer skirt.

L'actionneur est réalisé par moulage, typiquement en PP (polypropylène) ou un PE-HD (polyéthylène haute densité) ainsi que le capot.The actuator is made by molding, typically in PP (polypropylene) or PE-HD (high density polyethylene) as well as the cover.

L'actionneur est typiquement obtenu monobloc en moulage par injection, sa patte déformable constituant alors le pont entre ses deux parties. La coupelle déformable de l'invention est également moulée et en l'une des matières du groupe formé par: les polymères thermoplastiques, les résines silicones, le caoutchouc naturel et les caoutchoucs synthétiques. Des coupelles déformables de qualité particulièrement bonne ont été réalisées ainsi en polyester -éther.The actuator is typically obtained in one piece by injection molding, its deformable tab then constituting the bridge between its two parts. The deformable cup of the invention is also molded and made from one of the materials of the group formed by: thermoplastic polymers, silicone resins, natural rubber and synthetic rubbers. Deformable cups of particularly good quality have been produced in polyester ether.

L'invention a aussi pour objet le procédé de fabrication du corps de distibuteur dont le sommet porte un orifice ainsi qu'un clapet d'aspiration constitué d'un voile d'obturation s'appliquant sur le pourtour de l'orifice et d'une portion cylindrique sous-jacente engagée dans ledit orifice et portant à sa partie inférieure des reliefs de retenue, dans lequel :

  • A) on choisit comme reliefs de retenue des bossages transversaux laissant entre eux des portions de surface cylindrique, le diamètre du cylindre circonscrit à ces bossages étant supérieur de 1 à 2 mm au diamètre de l'orifice central;
  • B) on injecte sur le corps tubulaire du distributeur qui est en matière plastique ou métallo-plastique, une pièce en matière plastique reproduisant le sommet avec son orifice ainsi que le clapet, le bas de la portion cylindrique de ce clapet étant relié à la surface latérale de l'orifice du sommet par une couronne cassable d'épaisseur 0,1 à 0,3 mm;
  • C) après démoulage, on appuie sur le voile d'obturation du clapet de façon à casser la couronne cassable et à forcer les bossages transversaux au travers de l'orifice.
The subject of the invention is also the method of manufacturing the distributor body, the top of which carries an orifice, as well as a suction valve made up of a obturation veil applied on the periphery of the orifice and an underlying cylindrical portion engaged in said orifice and carrying at its lower part retaining reliefs, in which:
  • A) transverse bosses are chosen as retaining reliefs leaving portions of cylindrical surface between them, the diameter of the cylinder circumscribed by these bosses being 1 to 2 mm greater than the diameter of the central orifice;
  • B) a plastic part reproducing the top with its orifice and the valve, the bottom of the cylindrical portion of this valve being connected to the surface, is injected onto the tubular body of the distributor which is made of plastic or metallo-plastic material. lateral opening of the aperture by a breakable crown of thickness 0.1 to 0.3 mm;
  • C) after removal from the mold, the closure flap of the valve is pressed so as to break the frangible crown and force the transverse bosses through the orifice.

La description d'un exemple de distributeur selon l'invention, avec deux variantes de réalisation de son clapet d'aspiration, permettra de mieux en comprendre la structure et le fonctionnement.The description of an example of a dispenser according to the invention, with two alternative embodiments of its suction valve, will allow a better understanding of its structure and operation.

Le corps de distributeur dont le haut est seul représenté (figure 1) est en matière plastique, avec un corps tubulaire comprenant une jupe cylindrique 2 de diamètre extérieur 35 mm et d'épaisseur 1 mm en PE HD, jupe sur laquelle est surmoulé un sommet 3 en PE-HD muni d'un orifice central 4 de diamètre 22 mm avec sur le pourtour de cet orifice 4 une surface annulaire plane 5 de diamètre extérieur 30 mm. Le sommet 3 porte à sa périphérie une gorge circulaire 6 permettant la fixation de la tête de distribution 7 par encliquetage d'une nervure 8 de la partie inférieure de la jupe extérieure 9 de son actionneur 10.The distributor body, the top of which is only shown (FIG. 1) is made of plastic, with a tubular body comprising a cylindrical skirt 2 with an outside diameter of 35 mm and a thickness of 1 mm in HD PE, skirt on which a top is molded. 3 in HDPE provided with a central orifice 4 with a diameter of 22 mm with around the periphery of this orifice 4 a flat annular surface 5 with an external diameter of 30 mm. The apex 3 carries at its periphery a circular groove 6 allowing the dispensing head 7 to be fixed by snap-fastening of a rib 8 of the lower part of the outer skirt 9 of its actuator 10.

La tête de distribution 7 comporte deux pièces: la coupelle déformable 11 et l'actionneur 10 qui comprend lui-même, la jupe extérieure fixe 9 et la partie centrale inclinable 12 reliée à la jupe 9 par une patte déformable 13 qui rattache le dessous de son conduit de distribution 14 au bas d'une échancrure avant 15 de cette jupe 9. La partie centrale inclinable 12 de l'actionneur 10 comprend un voile d'appui 16 sur lequel on vient appuyer avec un doigt pour obtenir la distribution d'un peu de produit crémeux ou pâteux, et en-dessous de ce voile d'appui 16 une cheminée 17 au départ de laquelle débouche le conduit de distribbution 14. La cheminée 17 a une position et une géométrie telles que vient emboîter la tubulure supérieure 18 de la coupelle déformable 11 et elle comporte une gorge 19 permettant la fixation de cette tubulure 18 par encliquetage. La jupe extérieure 9 de l'actionneur 10 est fixée sur le sommet 3 du corps de distributeur 1 par l'encliquetage de sa nervure 8, elle comporte l'échancrure avant 15 de largeur 11 mm plus importante que la largeur 8 mm du conduit de distribution rectangulaire, et une échancrure arrière beaucoup plus grande 20 (figure 2) de largeur 20 mm et d e hauteur 17 mm permettant une emprise du doigt sur le voile d'appui 16 sans aucune gêne. Outre l'aisance de manipulation, les deux échancrures 15 et 20 procurent un mode d'appui et une orientation d'appui à peu près constants, entraînant un écrasement sans à-coup de la chambre de compression et une distribution régulière de produit. La jupe extérieure 9 comporte, en outre, un rebord extérieur d'appui 21 du capot 22. L'actionneur décrit est en polypropylène monobloc, avec des épaisseurs généralement comprises entre 1 et 1,2 mm à l'exception de la patte déformable 13 qui est plus mince (0,8 mm).The dispensing head 7 comprises two parts: the deformable cup 11 and the actuator 10 which itself comprises, the fixed outer skirt 9 and the central tilting part 12 connected to the skirt 9 by a deformable tab 13 which attaches the underside of its distribution duct 14 at the bottom of a front notch 15 of this skirt 9. The tilting central part 12 of the actuator 10 comprises a support veil 16 on which one comes to press with a finger to obtain the distribution of a little creamy or pasty product, and below this support veil 16 a chimney 17 at the start of which opens the distribution duct 14. The chimney 17 has a position and a geometry such that comes to fit the upper tube 18 of the deformable cup 11 and it has a groove 19 allowing the attachment of this tube 18 by snap-fastening. The outer skirt 9 of the actuator 10 is fixed to the top 3 of the distributor body 1 by the snap-fastening of its rib 8, it has the front notch 15 of width 11 mm greater than the width 8 mm of the conduit rectangular distribution, and a much larger rear notch 20 (FIG. 2) of width 20 mm and height 17 mm allowing a grip of the finger on the support veil 16 without any discomfort. In addition to ease of handling, the two notches 15 and 20 provide an almost constant mode of support and support orientation, resulting in a smooth crushing of the compression chamber and a regular distribution of product. The outer skirt 9 further comprises an outer support rim 21 of the cover 22. The actuator described is in one-piece polypropylene, with thicknesses generally between 1 and 1.2 mm with the exception of the deformable tab 13 which is thinner (0.8mm).

La coupelle déformable 11 est en polyester-éther moulé avec des épaisseurs qui varient de 1 mm pour la tubulure supérieure 18 à 0,2 mm environ pour l'extrémité de la lèvre souple supérieure 23. Le croisillon transversal 24 porté par l'intérieur de sa tubulure supérieure 18 correspond à l'alimentation de son moulage, il ne gêne par les écoulements de produit. En allant du bas vers le haut, la coupelle 11 comprend successivement une embase ou rebord inférieur circulaire 25, une tubulure inférieure 26, un voile déformable en forme de dôme 27, la tubulure supérieure 18 qui porte une fine nervure circulaire extérieure 28, de hauteur 0,5 mm qui vient se fixer dans la gorge d'encliquetage 19 de la cheminée 17 de l'actionneur 10, et enfin, surmontant cette tubulure 18, la lèvre souple supérieure 23. L'extrémité de la lèvre supérieure 23 a un diamètre de 12 mm et vient au montage se placer contre la surface plane 29 de dessous du voile d'appui 16 au fond de la cheminée 17 de l'actionneur 10 de diamètre intérieur 14 mm, lorsque cette cheminée 17 emboîte avec un jeu faible la tubulure 18 dans la gorge 19 de la cheminée 17. Dans la position de la figure 1, c'est-à-dire en fin d'aspiration ou au repos, la lèvre 23 est appliquée de façon étanche par retour élastique contre la surface 29.The deformable cup 11 is made of molded polyester ether with thicknesses which vary from 1 mm for the upper tube 18 to about 0.2 mm for the end of the upper flexible lip 23. The transverse crosspiece 24 carried by the interior of its upper tube 18 corresponds to the supply of its molding, it does not interfere with the flow of product. Going from bottom to top, the cup 11 successively comprises a base or circular lower rim 25, a lower tube 26, a deformable veil in the shape of a dome 27, the upper tube 18 which carries a thin outer circular rib 28, of height 0.5 mm which is fixed in the latching groove 19 of the chimney 17 of the actuator 10, and finally, surmounting this tube 18, the upper flexible lip 23. The end of the upper lip 23 has a diameter of 12 mm and comes to the assembly to be placed against the flat surface 29 below the support veil 16 at the bottom of the chimney 17 of the actuator 10 with an internal diameter of 14 mm, when this chimney 17 fits with the tubing with a small clearance 18 in the groove 19 of the chimney 17. In the position of FIG. 1, that is to say at the end of suction or at rest, the lip 23 is applied in a sealed manner by elastic return against the surface 29.

Le montage consiste ainsi en la fixation de la tubulure supérieure 18 de la coupelle déformable 11 dans l'actionneur 10. Le rebord inférieur 25 a une surface de dessus horizontale qui vient en face d'une surface intérieure d'appui 30 de la jupe extérieure 9 et, en outre, la tubulure inférieure 26 s'emboîte alors avec un jeu faible à l'intérieur d'une partie droite 31 de la jupe 9. La coupelle déformable 11 est ainsi à la fois reliée à la partie centrale inclinable 12 de l'actionneur et solidarisée à sa base avec la jupe extérieure 9. La tête de distribution 7 étant ainsi constituée par l'assemblage de ces deux pièces 10 et 11 est fixée sur le sommet 3 du corps de distributeur 1 par encliquetage de la nervure 8 de la jupe 9 dans la gorge 6 du sommet 3. La surface de dessous 32 du rebord inférieur 25 de la coupelle déformable 11 est horizontale sur sa partie intérieure et inclinée, c'est-à-dire tronconique, sur sa partie extérieure, ces deux parties de la surface 32 s'appuyant respectivement sur la périphérie de la surface annulaire plane 5 du sommet 3 et sur un chanfrein périphérique 33 de ce même sommet 3. La jupe extérieure 9 effectuant par sa partie droite 34 un serrage radial du rebord 25 et par sa surface d'appui 30 un serrage axial de ce même rebord 25, la disposition adoptée se montre particulièrement étanche.The assembly thus consists in fixing the upper tube 18 of the deformable cup 11 in the actuator 10. The lower flange 25 has a horizontal top surface which comes opposite an internal bearing surface 30 of the outer skirt 9 and, in addition, the lower tube 26 then fits with a slight clearance inside a straight part 31 of the skirt 9. The deformable cup 11 is thus both connected to the central tilting part 12 of the actuator and secured at its base with the outer skirt 9. The dispensing head 7 thus being constituted by the assembly of these two parts 10 and 11 is fixed to the top 3 of the dispenser body 1 by snap-fastening of the rib 8 of the skirt 9 in the groove 6 of the apex 3. The bottom surface 32 of the lower rim 25 of the deformable cup 11 is horizontal on its inner part and inclined, that is to say frustoconical, on its outer part, these two parts of the respective surface 32 supported ment on the periphery of the flat annular surface 5 of the apex 3 and on a peripheral chamfer 33 of this same apex 3. The outer skirt 9 carrying out by its straight part 34 a radial tightening of the flange 25 and by its bearing surface 30 an axial tightening of the same rim 25, the arrangement adopted is particularly sealed.

On voit aussi sur la figure 1 le clapet d'aspiration 35 constitué d'un voile d'obturation 36 plan, d'épaisseur 0.8 mm et de diamètre 26 mm et d'une portion cylindrique sous-jacente 37 munie à sa partie inférieure de bossages transversaux arrondis 38 de diamètre de cylindre circonscrit 23,5 mm, ces bossages de retenue 38 et le voile 36 retenant le clapet 35 dans l'orifice 4, et comportant en outre des reliefs arrondis longitudinaux 39, le diamètre hors-tout sur ces reliefs de guidage 39 étant de 20,5 mm et des portions de surface cylindrique intermédiaire 40 de diamètre 19 mm. La course axiale du clapet 35, limitée par les bossages de retenue 18, est de 3 mm et, le diamètre de l'orifice central étant de 22 mm, les reliefs du guidage 39 assurent le maintien en direction du clapet 35 ainsi que sa fermeture en appui sur la surface annulaire 5 au moment des compressions.We also see in Figure 1 the suction valve 35 consisting of a blanking veil 36 plane, 0.8 mm thick and 26 mm in diameter and an underlying cylindrical portion 37 provided at its lower part with rounded transverse bosses 38 of circumscribed cylinder diameter 23.5 mm, these retaining bosses 38 and the web 36 retaining the valve 35 in the orifice 4, and further comprising longitudinal rounded reliefs 39, the overall diameter on these guide reliefs 39 being 20.5 mm and intermediate cylindrical surface portions 40 of diameter 19 mm. The axial stroke of the valve 35, limited by the retaining bosses 18, is 3 mm and, the diameter of the central orifice being 22 mm, the reliefs of the guide 39 ensure the maintenance in the direction of the valve 35 as well as its closure resting on the annular surface 5 at the time of the compressions.

La figure 2 représente l'actionneur 10 en demi-vue de dessus, rendu inviolable par deux ponts cassables 41 situés transversalement et typiquement à peu près à 90° du plan de symétrie (XX) de l'actionneur 10 passant par l'axe du conduit de distribution 14, ces ponts 41 reliant le haut de la partie centrale inclinable 12 de l'actionneur 10 au haut de sa jupe 9. Au premier appui, qui incline la partie centrale 12 autour de l'extrémité fixe de la patte déformable 13, les ponts 41 se trouvent distendus et cassent. Ces ponts ont de préférence une extrémité amincie 42 du côté de l'habillage ou jupe 9 de sorte que leur partie cassée reste attachée à la partie mobile 12 de l'actionneur et ne gêne pas les mouvements ultérieurs.FIG. 2 represents the actuator 10 in half-view from above, made inviolable by two breakable bridges 41 situated transversely and typically approximately 90 ° from the plane of symmetry (XX) of the actuator 10 passing through the axis of the distribution duct 14, these bridges 41 connecting the top of the tilting central part 12 of the actuator 10 to the top of its skirt 9. At the first support, which inclines the central part 12 around the fixed end of the deformable tab 13 , the bridges 41 are stretched and break. These bridges preferably have a tapered end 42 on the side of the covering or skirt 9 so that their broken part remains attached to the movable part 12 of the actuator and does not hinder subsequent movements.

La demi figure 3 à gauche reprend une partie de la figure 1 : on est en phase d'aspiration, la coupelle déformable 11 a repris à peu près sa forme initiale, l'appui sur l'actionneur étant relâché, et la lèvre supérieure 23 de la coupelle 11 s'est dépliée élastiquement contre la surface plane 29 du voile d'appui 16 (figure 1) en fermant le haut de la chambre de compression 43. La flèche sinueuse 44 schématise le parcours du produit pâteux au travers de l'intervalle annulaire compris entre le clapet d'aspiration 35 qui est soulevé vers le haut par l'effet de dépression et le bord de l'orifice 4 d'épaisseur ou hauteur 1,2 mm. Le produit contourne les bossages de retenue 38 et passe le long des portions de surface cylindrique intermédiaire 40, qui présentent un maximum de jeu par rapport à l'orifice 4, et à un degré moindre le long des reliefs longitudinaux de guidage 39. On comprend l'importance des conditions de guidage et de jeu pour obtenir un bon fonctionnement du clapet 35, spécialement vis à vis de l'écoulement du produit pâteux.The half in figure 3 on the left takes up part of figure 1: we are in the suction phase, the deformable cup 11 has resumed roughly its initial shape, the support on the actuator being released, and the upper lip 23 of the cup 11 is elastically unfolded against the flat surface 29 of the support web 16 (FIG. 1) by closing the top of the compression chamber 43. The sinuous arrow 44 shows diagrammatically the path of the pasty product through the annular gap between the suction valve 35 which is raised upwards by the vacuum effect and the edge of the orifice 4 of thickness or height 1.2 mm. The product bypasses the retaining bosses 38 and passes along the intermediate cylindrical surface portions 40, which have a maximum of play with respect to the orifice 4, and to a lesser degree along the longitudinal guide reliefs 39. It is understood the importance of the guiding and clearance conditions to obtain proper operation of the valve 35, especially with respect to the flow of the pasty product.

La demi figure 3 à droite la coupelle 11 en fin de compression, la bas de la tubulure supérieure 18 relativement rigide butant sur le voile d'obturation 36 du clapet d'aspiration 35 qui est appliqué par la pression sur la surface annulaire plane 5 du sommet 3 du corps de distributeur 1. La compression de la chambre 43 produit l'expulsion du produit pâteux entre la lèvre supérieure 23 de la coupelle 11 et le fond 29 de la cheminée 17 (figure 1), cette lèvre supérieure 23 étant légèrement recourbée par le passage de ce courant pâteux qui se dirige vers le conduit de distribution 14. Au sujet de la phase de compression, il est intéressant de noter (figure 1) que l'appui sur l'actionneur est effectué sur la partie arrière 45 du voile d'appui 16, en arrière de l'axe de symétrie vertical Y de la coupelle 11, la patte déformable 13 de l'actionneur 10 servant d'articulation souple, ce qui donne un effet de levier pour la compression élastique de la coupelle 11 favorisant une compression et une expulsion régulières du produit pâteux.The half-figure 3 on the right the cup 11 at the end of compression, the bottom of the relatively rigid upper tube 18 abutting on the sealing web 36 of the suction valve 35 which is applied by pressure to the flat annular surface 5 of the top 3 of the distributor body 1. The compression of the chamber 43 produces the expulsion of the pasty product between the upper lip 23 of the cup 11 and the bottom 29 of the chimney 17 (FIG. 1), this upper lip 23 being slightly curved by the passage of this pasty current which goes towards the distribution duct 14. With regard to the compression phase, it is interesting to note (FIG. 1) that the pressing on the actuator is carried out on the rear part 45 of the support web 16, behind the vertical axis of symmetry Y of the cup 11, the deformable tab 13 of the actuator 10 serving as a flexible articulation, which gives a leverage effect for the elastic compression of the cup 11 promoting compression and regular expulsion of the pasty product.

La figure 4 représente la position du même clapet 35 moulé en même temps que le reste du sommet 3 du corps 1 du distributeur sur la jupe cylindrique 2 d'épaisseur 1 mm du corps tubulaire. Le bas de la portion cylindrique 37 du clapet 35 est relié au haut 46 de la surface latérale de l'orifice 4 par une couronne de matière plastique 47 d'épaisseur environ 0,15 mm et de largeur 1 0,7 à 1,5 mm, le pont d'injection (flèche) correspondant au centre du voile d'obturation 36. La poussée du clapet 35 vers le bas entraîne le passage des bossages de retenue 38 en-dessous de l'orifice 4.FIG. 4 represents the position of the same valve 35 molded at the same time as the rest of the top 3 of the body 1 of the distributor on the cylindrical skirt 2 of thickness 1 mm from the tubular body. The bottom of the cylindrical portion 37 of the valve 35 is connected to the top 46 of the lateral surface of the orifice 4 by a crown of plastic material 47 of thickness approximately 0.15 mm and width 1 0.7 to 1.5 mm, the injection bridge (arrow) corresponding to the center of the obturation veil 36. The thrust of the valve 35 downwards causes the retaining bosses 38 to pass below the orifice 4.

La figure 5 qui représente le clapet 35 vu de dessus, permet de compléter sa description géométrique commencée au sujet de la figure 1. Ses bossages transversaux de retenue 38 sont au nombre de 4 et espacés de 90°, ils ont un contour extérieur et un contour en section droite circulaires avec une largeur individuelle de 8 mm et une épaisseur de 1 mm. Ils se présentent comme des excroissances des 4 reliefs longitudinaux de guidage 39, chacun ayant un contour en section droite également circulaire et une la rgeur de 6 mm et s'étendant sur une hauter de 5 mm depuis le bas du clapet 35 jusqu'à son voile d'obturation 36, leur portion de guidage proprement dite étant celle comprise entre les bossages de retenue 38 et le voile 36 et de hauteur 3 mm. Le tracé en trait interrompu du contour de diamètre 22 mm de l'orifice 4 montre l'élargissement de l'intervalle de passage du produit pâteux en face des portions de surface cylindrique intermédiaires 40 de diamètre 19 mm.FIG. 5 which represents the valve 35 seen from above, makes it possible to complete its geometrical description begun with regard to FIG. 1. Its transverse retaining bosses 38 are 4 in number and spaced 90 ° apart, they have an outer contour and a contour in section straight circular with an individual width of 8 mm and a thickness of 1 mm. They appear as protuberances of the 4 longitudinal guide reliefs 39, each having a contour in cross section also circular and a width of 6 mm and extending over a height of 5 mm from the bottom of the valve 35 to its shutter web 36, their guide portion proper being that between the retaining bosses 38 and the web 36 and 3 mm high. The dashed line of the 22 mm diameter contour of the orifice 4 shows the widening of the pasty product passage interval in front of the intermediate cylindrical surface portions 40 of diameter 19 mm.

Sur la figure 6, on voit un clapet 350 dont le voile d'obturation 360, de même pourtour 361 que le voile 36 du clapet précédent 35, est en forme de cuvette. De façon à permettre une compression plus grande de la coupelle 11, la partie centrale 362 de ce voile 360 est abaissée de 3 mm à l'intérieur de la portion cylindrique 370, et on peut remarquer que ce voile 360 est alors complété dans sa fonction d'obturation par la partie haute 362 de la portion cylindrique 370. L'extrémité inférieure de cette portion cylindrique 370 comporte une couronne extérieure 371 d'épaisseur 0,7 mm et de diamètre 20,5 mm et la couronne de matière plastique 470 d'épaisseur 0,15 mm qui relie le haut 46 de l'orifice 4 au haut de cette couronne extérieure 371 a une largeur à peu près constante de 0,7 à 0,8 mm. La rupture en est particulièrement facile.In FIG. 6, a valve 350 is seen, the shutter veil 360, the same periphery 361 as the veil 36 of the preceding valve 35, is in the form of a bowl. In order to allow greater compression of the cup 11, the central part 362 of this veil 360 is lowered by 3 mm inside the cylindrical portion 370, and it can be noted that this veil 360 is then completed in its function for closure by the upper part 362 of the cylindrical portion 370. The lower end of this cylindrical portion 370 comprises an outer ring 371 0.7 mm thick and 20.5 mm in diameter and the plastic ring 470 d 'thickness 0.15 mm which connects the top 46 of the orifice 4 to the top of this outer ring 371 has a roughly constant width of 0.7 to 0.8 mm. Breaking up is particularly easy.

Sur la figure 7 représentant une vue de dessus du même clapet 350, on voit qu'il y a 4 bossages de retenue 380 espacés à 90° comme ceux du clapet 35 et portés par 4 bossages longitudinaux de guidage 390 de largeur 4 mm. Il y a en outre 4 bossages longitudinaux intermédiaires 391, correspondant au même diamètre hors-tout 20,5 mm que celui des bossages 390, de section droite sensiblement demi-circulaire et de rayon 1 mm. Ces 8 bossages de guidage 390 et 391 portés par la portion cylindrique 370 et répartis régulièrement sur sa périphérie s'étendent depuis la courrone extérieure 371 jusqu'au pourtour 361 du voile d'obturation 360; leur nombre et leurs courbures relativement fortes procurent une bonne régularité de fonctionnement du clapet 350.In Figure 7 showing a top view of the same valve 350, it can be seen that there are 4 retaining bosses 380 spaced at 90 ° like those of the valve 35 and carried by 4 longitudinal guide bosses 390 of width 4 mm. There are also 4 intermediate longitudinal bosses 391, corresponding to the same overall diameter 20.5 mm as that of the bosses 390, of substantially semi-circular cross section and radius 1 mm. These 8 guide bosses 390 and 391 carried by the cylindrical portion 370 and distributed regularly over its periphery extend from the outer ring 371 to the periphery 361 of the obturation veil 360; their number and their relatively strong curvatures provide good regularity of operation of the valve 350.

De façon générale, il est souhaitable d'avoir pour un clapet selon l'invention se déplaçant typiquement à l'intérieur d'un orifice de 15 à 30 mm de diamètre : de 3 à 6 bossages de retenue, et de 4 à 12 bossages longitudinaux de guidage. On peut se passer de bossages de guidage, mais les résultats de fonctionnement du distributeur sont alors moins bons.In general, it is desirable to have for a valve according to the invention typically moving inside an orifice 15 to 30 mm in diameter: from 3 to 6 retaining bosses, and from 4 to 12 longitudinal guide bosses. Guide bosses can be dispensed with, but the distributor's operating results are therefore less good.
