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.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.

EXPOSE DU PROBLEMEEXPOSURE OF THE PROBLEM

La demanderesse a cherché à répondre aux impératifs suivants, dans le cadre d'une fabrication en grande série : nombre faible de pièces à assembler et nombre faible d'interventions manuelles, facilité du montage et fiabilité du fonctionnement avec amélioration de certaines pièces.The Applicant has sought to meet the following requirements, in the context of mass production: low number of parts to be assembled and low number of manual interventions, ease of assembly and reliability of operation with improvement of certain parts.

ETAT DE LA TECHNIQUE CONNUEKNOWN STATE OF THE ART

Le document EP-A-0048421 décrit un distributeur pour produits pâteux dont le corps porte,à sa partie supérieure, une soupape de refoulement du produit pâteux de la chambre de stockage vers la chambre de pompage ou de refoulement, 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 moyeu fixé lui-même à un axe ou un ér- got 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'expulsion du produit pâteux et son refoulement de la chambre de stockage vers la chambre de pompage ou de refoulement (chambre dite encore : chambre de compression). La soupape d'admission ou 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'admission, de refoulement et de compression, se fait ainsi avec 5 pièces, ou encore 3 pièces en plus du corps de distributeur et de 1'actionneur. La pièce annulaire d'obturation des fenêtres de passage du produit de la chambre de stoekage à la chambre de pompage ou de cocompressiom est assez fragile.Document EP-A-0048421 describes a dispenser for pasty products, the body of which carries, at its upper part, a valve for discharging the pasty product from the storage chamber towards the pumping or discharge chamber, this valve comprising a seat with lateral passage windows and an annular blocking part for these windows, a part connected by at least three flexible spokes to a hub which is itself fixed to an axis or a central nipple of the underlying seat. The dome of the head fixed by snap-fastening on the body is flexible and crushable, allowing the expulsion of the pasty product and its discharge from the storage chamber towards the pumping or discharge chamber (also known as: compression chamber). The valve for admitting or expelling the product to the conduit and the dispensing orifice has its seat at the end of the tubing surmounting the dome and comprises a valve which is fixed inside the actuator. The assembly of the intake, discharge and compression means is thus done with 5 pieces, or even 3 pieces in addition to the distributor body and the actuator. The annular blocking part of the windows for the passage of the product from the stoekage chamber to the pumping or co-compression chamber is quite fragile.

La demanderesse a cherché à simplifier cet ensemble de pièces appartenant à la tête de distribution, c'est-à-dire situées au-dessus ou en aval de la chambre de stockage du produit pâteux ou crémeux.The plaintiff sought to simplify this set of parts belonging at the dispensing head, that is to say located above or downstream of the storage chamber for the pasty or creamy product.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention a pour objet une tête de distribution de produits crémeux ou pâteux, pour adaptation sur un corps de distributeur connu en lui-même et qui comprend un corps tubulaire, un piston à lèvre souple coulissant de façon étanche à l'intérieur de ce corps tubulaire, et un sommet muni d'orifices de passage et portant une surface centrale d'appui ainsi que, à sa périphérie, des moyens de fixation de la tête de distribution. Cette tête de distribution comprend elle-même de façon connue :

  • a) des moyens d'aspiration et de refoulement
  • b) un actionneur comportant un voile d'appui et un conduit de distribution
  • c) éventuellement, un capot.
    et selon l'invention, elle comprend :
  • a1)une coupelle déformable, qui forme avec le voile d'appui de l'actionneur un clapet d'aspiration, et avec la surface centrale d'appui du sommet du corps du distributeur un clapet de refoulement;
  • bl)un actionneur qui comprend d'une part une partie fixe comportant une jupe extérieure qui porte à sa base un moyen de fixation sur le sommet du corps de distributeur, et d'autre part une partie centrale inclinable reliée à la partie fixe.

En outre, la coupelle déformable et la partie centrale inclinable de l'actionneur comportent des moyens complémentaires de fixation étanche de ladite coupelle à ladite partie centrale inclinable.The subject of the invention is a head for dispensing creamy or pasty products, for adaptation to a dispenser body known in itself and which comprises a tubular body, a flexible lip piston sliding in leaktight manner inside this. tubular body, and a top provided with through orifices and carrying a central bearing surface as well as, at its periphery, means for fixing the dispensing head. This dispensing head itself comprises in a known manner:
  • a) suction and discharge means
  • b) an actuator comprising a support veil and a distribution duct
  • c) possibly, a cover.
    and according to the invention, it comprises:
  • a1) a deformable cup, which forms with the actuating support veil a suction valve, and with the central support surface of the top of the distributor body a delivery valve;
  • bl) an actuator which comprises on the one hand a fixed part comprising an outer skirt which carries at its base a means of fixing on the top of the distributor body, and on the other hand a tilting central part connected to the fixed part.

In addition, the deformable cup and the tilting central part of the actuator comprise complementary means for sealingly sealing said cup to said tilting central part.

La coupelle déformable de l'invention définit la chambre de pompage ou de compression, et à elle seule, elle remplace trois pièces du système décrit par EP-A-0048421 : la pièce annulaire d'obturation de la soupape de refoulement, le dôme souple et écrasable de la tête et le clapet d'admissicn. Le montage est très facile : la coupelle 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.The deformable cup of the invention defines the pumping or compression chamber, and by itself it replaces three parts of the system described by EP-A-0048421: the annular blocking part of the discharge valve, the flexible dome and crushable of the head and the admittance valve. Assembly is very easy: the 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.

De façon typique, la coupelle déformable de l'invention est monobloc et comprend successivement : un moyen de fixation sur le sommet du corps de distributeur, puis une tubulure inférieure portant une lèvre intérieure souple qui constitue avec la surface centrale d'appui du sommet du corps de distributeur un clapet de refoulement, puis un voile déformable, puis une tubulure supérieure portant un moyen de fixation étanche à la partie centrale inclinable de l'actionneur et surmontée d'une lèvre supérieure souple. Et le dessous du voile d'appui de la partie centrale mobile de l'actionneur comporte vis-à-vis de cette lèvre supérieure souple une surface formant avec cette lèvre un clapet d'aspiration.Typically, the deformable cup of the invention is in one piece and successively comprises: a fixing means on the top of the distributor body, then a lower tube carrying a flexible inner lip which constitutes with the central bearing surface of the top of the distributor body a discharge valve, then a deformable veil, then an upper tube carrying a sealed fixing means to the tilting central part of the actuator and surmounted by a flexible upper lip. And the underside of the supporting veil of the movable central part of the actuator comprises, opposite this flexible upper lip, a surface forming with this lip a suction valve.

Pour que l'extrémité de la lèvre intérieure souple de la coupelle déformable ait de façon reproductible une forme circulaire après démoulage, il est préférable qu'elle comporte un épaississement s'étendant typiquement sur 0,5 à 1,5 mm à partir de son bord extrême. De préférence, cet épaississement est situé sur la face de la lèvre intérieure souple qui est opposée à sa face d'appui sur la surface centrale d'appui du corps du distributeur, et l'épaisseur maximale correspondante de la tubulure est 2 à 4 fois l'épaisseur de la lèvre intérieure avant cet épaississement.In order that the end of the flexible inner lip of the deformable cup reproducibly has a circular shape after demolding, it is preferable for it to have a thickening, typically extending over 0.5 to 1.5 mm from its extreme edge. Preferably, this thickening is located on the face of the flexible inner lip which is opposite its bearing face on the central bearing surface of the body of the distributor, and the corresponding maximum thickness of the tubing is 2 to 4 times the thickness of the inner lip before this thickening.

De façon typique également, le dessous du voile d'appui de l'actionneur porte une cheminée qui emboîte la tubulure supérieure de la coupelle déformable qui vient d'être décrite, et le conduit de distribution de l'actionneur débouche dans cette cheminée. La tubulure supérieure de la coupelle déformable et la cheminée précédente portent alors des moyens complémentaires de fixation étanche qui coopèrent 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.Also typically, the underside of the actuator support veil carries a chimney which fits the upper tube of the deformable cup which has just been described, and the actuator distribution duct opens into this chimney. The upper tubing of the deformable cup and the preceding chimney then carry complementary tight fixing means which cooperate during the fitting of the tubing by the chimney, for example a circular rib outside the tubing and a circular groove from the inside. from the fireplace.

Le moyen de fixation de la coupelle déformable sur le sommet du corps de distributeur est de façon avantageuse un simple rebord inférieur circulaire, incliné par rapport à l'axe ou à 90° de cet axe, qui vient s'appuyer sur une surface périphérique d'appui du sommet du corps de distributeur, la jupe extérieure de la partie fixe de l'actionneur comportant elle-même une surface intérieure d'appui complémentaire, de sorte que, au montage, la fixation de la jupe extérieure de l'actionnneur, réalisant la fixation de la tête de distribution sur le sommet du corps de distributeur, entraîne le serrage étanche du rebord inférieur de la coupelle déformable entre la surface intérieure d'appui de la jupe de l'actionneur et la surface d'appui du sommet du corps de distributeur.The means of fixing the deformable cup on the top of the body dispenser is advantageously a simple circular lower edge, inclined relative to the axis or at 90 ° to this axis, which comes to rest on a peripheral support surface of the top of the distributor body, the outer skirt of the fixed part of the actuator itself comprising an additional internal bearing surface, so that, during assembly, the fixing of the outer skirt of the actuator, making the fixing of the dispensing head on the top of the body of distributor, causes the tight tightening of the lower rim of the deformable cup between the internal bearing surface of the actuator skirt and the bearing surface of the top of the distributor body.

Pour la facilité du montage et pour le bon maintien de la base de la coupelle pendant sa compression et son relâchement opérés par la manipulation de l'actionneur, il a également été trouvé avantageux de prévoir un emboîtement avec jeu faible - de préférence moins de 0,3 mm au rayon - de la tubulure inférieure de la coupelle déformable par le jupe extérieure de l'actionneur.For the ease of assembly and for the good maintenance of the base of the cup during its compression and its relaxation operated by the manipulation of the actuator, it has also been found advantageous to provide an interlocking with a small clearance - preferably less than 0 , 3 mm to the radius - of the lower tubing of the cup deformable by the outer skirt of the actuator.

Enfin, l'actionnneur, dont divers aspects ont déjà été décrits, est typiquement monobloc, avec une jupe extérieure échancrée 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 d'une échancrure de la jupe. Les échancrures facilitent alors l'opération de l'actionnneur 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.Finally, the actuator, various aspects of which have already been described, is typically monobloc, with an indented outer skirt and a tilting central part connected to this skirt by a deformable tab extending from below the distribution conduit to the bottom. a notch in the skirt. The notches then 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 de l'invention est réalisé par moulage, typiquement en PP (polypropylène) ou PE-HD (polyéthylène haute densité). Il en est de même du capot. 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 of the invention is produced by molding, typically in PP (polypropylene) or PE-HD (high density polyethylene). The same goes for the hood. 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.

La description d'un exemple de tête de distribution selon l'invention permettra de mieux en comprendre la structure et le fonctionnement.The description of an example of a dispensing head according to the invention will make it possible to better understand its structure and operation.

La figure.2 représente une tête de distribution selon l'invention rendue inviolable, en demi-vue de dessus.Figure.2 shows a dispensing head according to the invention made inviolable, in half-view from above.

Le corps de distributeur (1) dont le haut est seul représenté, est en matière plastique, avec un corps tubulaire comprenant une jupe cylindrique (2) de diamètre extérieur 40 mm et d'épaisseur 0,8 mm en PE HD, jupe sur laquelle est surmoulé un sommet (3) en PE-HD muni de 6. orifices de passage (4) incurvés, de longueur moyenne 12 mm et de largeur 2 mm, avec entre ses orifices une surface centrale d'appui (5) de diamètre 23 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 (1), the top of which is only shown, is made of plastic, with a tubular body comprising a cylindrical skirt (2) with an outside diameter of 40 mm and a thickness of 0.8 mm in HD PE, skirt on which a PE-HD top (3) is overmolded provided with 6. curved passage orifices (4), of average length 12 mm and width 2 mm, with between its orifices a central support surface (5) of diameter 23 mm. The top (3) carries at its periphery a circular groove (6) allowing the fixing of the dispensing head (7) 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 souple (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'actionnneur (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 distribution (14). La cheminée (17) a une position et une géométrie telles qu'elle 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 juge extérieure (9) de l'actionneur (10) est fixée sur le sommet (3) du corps de distributeur (1) comme il a déjà été expliqué, 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 de 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 constante, 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 tilting central part (12) connected to the skirt (9 ) by a flexible tab (13) which connects the underside of its distribution duct (14) to 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 web (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 it fits the upper tube (18) of the deformable cup (11), and it has a groove (19) allowing the fixing of this tube (18) by snap-fastening . The outer judge (9) of the actuator (10) is fixed to the top (3) of the distributor body (1) as already explained, it includes the front notch (15) of width 11 mm more important than the width 8 mm of the rectangular distribution duct, 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 no discomfort. In addition to the ease of handling, the two notches (15) and (20) provide a support mode and an approximately constant 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 made of one-piece polypropylene, with thicknesses generally between 1 and 1.2 mm with the exception of the deformable tab (13) which is thinner (0.8 mm).

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 les extrémités des lèvres souples inférieure (23) et supérieure (24). Le croisillon transversal (34) porté par l'intérieur de sa tubulure supérieure (18) correspond à l'alimentation de son moulage, il ne gêne pas 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) dont le haut porte la lèvre souple inférieure (23), 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 (24). L'extrémité de la lèvre inférieure (23) a un diamètre moyen de 20 mm, qui s'inscrit dans la surface centrale d'appui (5) du sommet (3) du corps de distributeur (1), et l'extrémité de la lèvre supérieure (24) a un diamètre de 12 mm et vient au montage se placer contra la surface plane (32) 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 supérieure (18) jusqu'à l'encliquetage de la nervure (28) de cette tubulure (18) dans la gorge (19) de la cheminée (17). Dans la position réalisée, la lèvre (24) est appliquée de façon étanche contre la surface (32).The deformable cup (11) is made of molded polyester ether with thicknesses which vary from 1 mm for the upper tube (18) to approximately 0.2 mm for the ends of the lower flexible lips (23) and upper (24). The transverse spider (34) carried by the interior of its upper tube (18) corresponds to the supply of its molding, it does not hinder the flow of product. Going from bottom to top, the cup (11) successively comprises a circular lower base or rim (25), a lower tube (26) the top of which carries the lower flexible lip (23), a deformable veil in the shape of a dome (27), the upper tube (18) which carries a thin outer circular rib (28), 0.5 mm high, which is fixed in the latching groove (19) of the chimney (17) of the actuator (10), and finally, overcoming this tubing (18), the upper flexible lip (24). The end of the lower lip (23) has an average diameter of 20 mm, which fits into the central bearing surface (5) of the top (3) of the distributor body (1), and the end of the upper lip (24) has a diameter of 12 mm and comes to assembly to be placed against the flat surface (32) of the underside of the bearing 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 the upper tube (18) with a slight clearance until the rib (28) of this tube (18) engages in the groove (19) of the chimney (17). In the position carried out, the lip (24) is applied in leaktight manner against the surface (32).

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) vient en face d'une surface intérieure d'appui (29) 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 (30) 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). Le dessous du rebord inférieur (25) de la coupelle déformable vient alors se placer contre une surface d'appui du sommet (3) consistant en un chanfrein périphérique (31), de sorte que ce rebord inférieur (16) se trouve serré de façon étanche entre la surface intérieure d'appui (29) de la jupe (9) et ce chanfrein (31). De plus, la lèvre inférieure (23) se trouve appliquée de façon étanche contre la surface d'appui (5) du sommet (3).The assembly thus consists of fixing the upper tube (18) of the deformable cup (11) in the actuator (10). The lower flange (25) comes opposite an inner bearing surface (29) of the outer skirt (9) and, in addition, the lower tube (26) then fits together with a slight clearance inside. a straight part (30) of the skirt (9). The deformable cup (11) is thus both connected to the tilting central 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 top (3). The underside of the lower rim (25) of the deformable cup is then placed against a bearing surface of the top (3) consisting of a peripheral chamfer (31), so that this lower rim (16) is tightened so tight between the inner bearing surface (29) of the skirt (9) and this chamfer (31). In addition, the lower lip (23) is applied sealingly against the bearing surface (5) of the top (3).

La figure 2 représente l'actionneur en demi-vue de dessus, rendu inviolable par 2 ponts cassables (33) 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 (33) 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 (33) se trouvent distendus et cassent. Ces ponts ont de préférence une extrémité amincie (36) du côté de l'habillage (29) 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 in half-view from above, made inviolable by 2 breakable bridges (33) situated transversely and typically approximately 90 ° from the plane of symmetry (XX) of the actuator (10) passing through l axis of the distribution duct (14), these bridges (33) 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 (33) are stretched and break. These bridges preferably have a tapered end (36) on the side of the covering (29) so that their broken part remains attached to the movable part (12) of the actuator and does not hinder subsequent movements.

Le fonctionnement de la distribution du produit crémeux ou pâteux, connu dans son principe, mérite d'être précisé ici avec la tête de distribution de l'invention. Au premier appui, après rupture des ponts d'inviolabilité, le clapet de refoulement (23, 5) formé par la lèvre inférieure ou lèvre de refoulement (23) de la coupelle (11) et la surface centrale d'appui (5) du sommet (3) du corps de distributeur étant fermé, la pression de la chambre de compression (35) délimitée par l'intérieur de la coupelle déformable (11) et par les surfaces d'appui (5) et (32) augmente et fait ouvrir le clapet d'aspiration (24, 32) formé par la lèvre supérieure (24) et la surface d'appui (32). Au relâchement, ce clapet (24, 32) se ferme, la chambre de compression (35) revient à son volume initial, ce qui y crée une dépression qui fait ouvrir le clapet de refoulement (23, 5) par soulèvement de la lèvre inférieure (23) et met en dépression la chambre de stockage du produit comprise entre le sommet (3) du corps de distributeur (1) et son piston coulissant (non représenté). Le piston remonte alors en poussant la colonne du produit crémeux ou pâteux à travers les orifices (4) et par dessous la lèvre (23), une partie du produit passe ainsi dans la chambre de compression (35).The operation of the distribution of the creamy or pasty product, known in principle, deserves to be specified here with the dispensing head of the invention. At the first press, after rupture of the tamper-evident bridges, the discharge valve (23, 5) formed by the lower lip or discharge lip (23) of the cup (11) and the central support surface (5) of the top (3) of the distributor body being closed, the pressure of the compression chamber (35) delimited by the interior of the deformable cup (11) and by the bearing surfaces (5) and (32) increases and to open the suction valve (24, 32) formed by the upper lip (24) and the bearing surface (32). Upon release, this valve (24, 32) closes, the compression chamber (35) returns to its initial volume, which creates a depression there which opens the discharge valve (23, 5) by lifting the lower lip. (23) and lowers the product storage chamber between the top (3) of the distributor body (1) and its sliding piston (not shown). The piston then rises by pushing the column of the creamy or pasty product through the orifices (4) and from below the lip (23), part of the product thus passes into the compression chamber (35).

Ensuite, à chaque pressée sur la partie centrale inclinable (12) de l'actionneur (10), le clapet de refoulement (23, 5) est fermé, le produit contenu dans la chambre (35) est comprimé et une partie de ce produit est éjectée au travers du clapet d'aspiration (24, 32) et du conduit de distribution (14). Lorsqu'on relâche la pression sur l'actionneur (10), on remplit à nouveau la chambre de compression (35) grâce à un nouveau passage de produit à travers le clapet de refoulement (23, 5).Then, each time the central tilting part (12) of the actuator (10) is pressed, the discharge valve (23, 5) is closed, the product contained in the chamber (35) is compressed and part of this product is ejected through the suction valve (24, 32) and the distribution duct (14). When the pressure on the actuator (10) is released, the compression chamber (35) is again filled by means of a new passage of product through the discharge valve (23, 5).
