La tête de distribution 1 est constituée d'un embout 4, à fixer dans le col 2 et d'une capsule 5 réalisée d'un seul tenant avec l'embout 4 et formée par la réunion d'un corps annulaire 6, d'un couvercle pivotant 7 et d'un rabat pivotant 8.There is shown in Figures 1 to 3 a dispensing head 1 according to a first embodiment of the invention, intended to be mounted on the neck 2 of a container 3 known in itself and produced for example by a injection-blowing technique. The dispensing head 1 consists of a nozzle 4, to be fixed in the neck 2 and of a capsule 5 produced integrally with the nozzle 4 and formed by the union of an annular body 6, of a pivoting cover 7 and a pivoting flap 8.

L'embout 4 comporte deux jupes tubulaires 9, 10 coaxiales d'axe X, de section transversale circulaire, réunies en 11 à leur extrémité inférieure. La jupe tubulaire radialement la plus externe, référencée 10, se prolonge radialement vers l'extérieur à son extrémité supérieure pour former un rebord annulaire 12 recourbé vers le bas, conformé pour s'engager sur la tranche d'extrémité supérieure du col 2. La jupe tubulaire 9 radialement la plus interne se prolonge axialement à son extrémité supérieure au-delà du rebord annulaire 12 comme représenté sur la figure 1. Le rebord annulaire 12 est évidé sur un secteur angulaire limité de sa périphérie pour former une découpe 13 destinée à coopérer avec un ergot 14 de forme complémentaire formant saillie sur la surface radialement externe du col 2 pour immobiliser en rotation l'embout 4 sur le col 2. La jupe tubulaire 9 est ajourée à partir de sa tranche d'extrémité supérieure, sur un secteur angulaire limité de sa périphérie, pour former une ouverture latérale 15 pour le passage de produit comme cela sera précisé dans la suite.The end piece 4 comprises two tubular skirts 9, 10 coaxial with axis X, of circular cross section, joined at 11 at their lower end. The radially outermost tubular skirt, referenced 10, extends radially outward at its upper end to form an annular rim 12 curved downward, shaped to engage the upper end edge of the neck 2. The radially innermost tubular skirt 9 extends axially at its upper end beyond the annular rim 12 as shown in FIG. 1. The annular rim 12 is hollowed out over a limited angular sector of its periphery to form a cutout 13 intended to cooperate with a lug 14 of complementary shape projecting from the radially external surface of the neck 2 to immobilize in rotation of the nozzle 4 on the neck 2. The tubular skirt 9 is perforated from its upper end edge, over a limited angular sector of its periphery, to form a lateral opening 15 for the passage of product as will be specified in the following.

Le diamètre externe de la jupe tubulaire 10 est choisi de manière à ce que l'embout 4 s'ajuste à force de façon étanche dans le col 2. La jupe tubulaire 9 délimite intérieurement un canal 16 pour le passage de produit depuis l'intérieur du récipient 3. L'embout 4, une fois en place dans le col 2, diminue la section de passage offerte à l'écoulement de produit quittant le récipient 3 par le col 2.The external diameter of the tubular skirt 10 is chosen so that the end piece 4 adjusts by force in a sealed manner in the neck 2. The tubular skirt 9 internally delimits a channel 16 for the passage of product from the interior of the container 3. The nozzle 4, once in place in the neck 2, reduces the passage section offered to the flow of product leaving the container 3 through the neck 2.

Le corps annulaire 6 présente une paroi 6a de forme générale tubulaire, de section transversale circulaire centrée sur l'axe X, sur laquelle sont formées au moins deux languettes flexibles de retenue 18 diamétralement opposées, munies à leur extrémité inférieure de bossages 19 formant radialement saillie sur la surface interne de la paroi 6a, destinés à s'encliqueter sur un bourrelet annulaire 20 formant radialement saillie sur la surface externe du col 2 comme représenté sur les figures 2 et 3. La paroi 6a est pourvue à son extrémité inférieure d'une collerette 21 formant radialement saillie sur sa surface externe. Le couvercle pivotant 7 et le rabat pivotant 8 sont reliés à la collerette 21, en des emplacements diamétralement opposés, par l'intermédiaire de ponts de matière formant charnières respectivement référencés 22 et 23.The annular body 6 has a wall 6a of generally tubular shape, of circular cross section centered on the axis X, on which are formed at least two flexible retaining tongues 18 diametrically opposed, provided at their lower end with bosses 19 forming radially projecting on the internal surface of the wall 6a, intended to snap onto an annular bead 20 radially projecting from the external surface of the neck 2 as shown in FIGS. 2 and 3. The wall 6a is provided at its lower end with a flange 21 radially projecting from its outer surface. The pivoting cover 7 and the pivoting flap 8 are connected to the collar 21, at diametrically opposite locations, by means of material bridges forming hinges respectively referenced 22 and 23.

Des ponts de matière 17 relient la surface radialement la plus externe du rebord annulaire 12 de l'embout 4 à la surface radialement interne du corps annulaire 6 au voisinage de sa tranche d'extrémité supérieure.Material bridges 17 connect the radially outermost surface of the annular rim 12 of the end piece 4 to the surface radially internal to the annular body 6 in the vicinity of its upper end edge.

Le couvercle pivotant 7 présente une coque externe 24 ayant la forme générale d'un dôme aplati en 27 à son sommet et comporte intérieurement deux tubulures coaxiales 25 et 26 se raccordant sur la face interne de la paroi aplatie 27 de la coque 24. Un canal de passage de produit est formé dans l'épaisseur de la paroi 27, débouchant à une extrémité dans l'espace annulaire 30 formé entre les tubulures 25 et 26 et à l'autre extrémité sur un orifice de distribution 29 situé sur la paroi latérale de la coque 24. Cette dernière est évidée en 31 sensiblement à l'aplomb de l'orifice de distribution 29 pour la fixation du rabat pivotant 8 sur le couvercle pivotant 7. Le diamètre interne de la tubulure 25 ainsi que l'épaisseur de sa paroi sont choisis de manière à ce que lorsque le couvercle pivotant 7 est rabattu sur le corps annulaire 6, la tubulure 25 s'engage dans la gorge annulaire 32 formée entre les jupes tubulaires 9 et 10 et s'ajuste de façon étanche sur la surface radialement interne de la jupe tubulaire 10. De façon plus générale, la tubulure 25 et la jupe tubulaire 9 sont conformées de manière à permettre, compte-tenu de la géométrie du pont de matière 22, le montage de l'une sur l'autre. Le diamètre externe de la tubulure 26 est choisi de manière à ce que cette dernière se loge à l'intérieur de la jupe tubulaire 9 lorsque le couvercle pivotant 7 est en place sur le corps annulaire 6. Le pont de matière 22 est réalisé avec une conformation en V et sa longueur est choisie de manière à conférer au couvercle pivotant 7 la mobilité nécessaire pour engager la tubulure 25 sur la jupe tubulaire 9.The pivoting cover 7 has an outer shell 24 having the general shape of a flattened dome at 27 at its apex and internally comprises two coaxial tubes 25 and 26 connecting on the internal face of the flattened wall 27 of the shell 24. A channel product passage is formed in the thickness of the wall 27, opening at one end into the annular space 30 formed between the pipes 25 and 26 and at the other end on a dispensing orifice 29 located on the side wall of the shell 24. The latter is hollowed out at 31 substantially perpendicular to the dispensing orifice 29 for fixing the pivoting flap 8 on the pivoting cover 7. The internal diameter of the tube 25 as well as the thickness of its wall are chosen so that when the pivoting cover 7 is folded over the annular body 6, the tube 25 engages in the annular groove 32 formed between the tubular skirts 9 and 10 and fits tightly on the s radially internal surface of the tubular skirt 10. More generally, the tubing 25 and the tubular skirt 9 are shaped so as to allow, given the geometry of the material bridge 22, the mounting of one on the other. The external diameter of the tubing 26 is chosen so that the latter is housed inside the tubular skirt 9 when the pivoting cover 7 is in place on the annular body 6. The material bridge 22 is produced with a V-shaped and its length is chosen so as to give the pivoting cover 7 the mobility necessary to engage the tubing 25 on the tubular skirt 9.

Le rabat pivotant 8 est conformé pour se fixer sur la surface externe latérale du couvercle pivotant 7 et présente un picot 33 apte à s'engager dans l'évidement 31, pour retenir le rabat pivotant 8 appliqué sur le couvercle pivotant 7. Une lame élastique, effilée, est surmoulée sur la paroi rigide constituant le reste du rabat pivotant 8 pour former un clapet 34 recouvrant au repos l'orifice de distribution 29.The pivoting flap 8 is shaped to be fixed on the lateral external surface of the pivoting cover 7 and has a pin 33 capable of engaging in the recess 31, to retain the pivoting flap 8 applied to the pivoting cover 7. An elastic blade , tapered, is molded onto the rigid wall constituting the rest of the pivoting flap 8 to form a valve 34 covering the dispensing orifice 29 at rest.

Le picot 13 est réalisé en matière plastique rigide. En variante il peut être réalisé en matière plastique souple auquel cas il est avantageusement surmoulé avec le clapet (variante non représentée).The pin 13 is made of rigid plastic. Alternatively it can be made of flexible plastic in which case it is advantageously overmolded with the valve (variant not shown).

Selon une caractéristique avantageuse de l'invention, embout 4 et capsule 5 sont réalisés d'un seul tenant en matière plastique, ce qui simplifie la manutention de la tête de distribution 1 ainsi que sa mise en place sur le récipient 3. Après moulage de l'embout 4 et de la capsule 5 dans la configuration représentée sur la figure 1, c'est-à-dire avec le rabat pivotant 8 s'étendant sensiblement perpendiculairement à l'axe X et les axes des tubulures 25 et 26 orientés sensiblement parallèlement à l'axe X, le corps annulaire 6 est encliqueté sur le col 2 du récipient (après remplissage de ce dernier) puis le couvercle 7 et le rabat 8 sont pivotés vers le corps annulaire 6 respectivement de 180° et de 90° environ et solidarisés par insertion à force du picot 33 dans l'évidement 31. L'immobilisation en rotation de l'embout 4 par rapport au col 2 est garantie grâce à la coopération de formes entre l'ergot 14 et la découpe 13.According to an advantageous characteristic of the invention, end piece 4 and capsule 5 are made in one piece of plastic material, which simplifies the handling of the dispensing head 1 as well as its positioning on the container 3. After molding of the end piece 4 and of the capsule 5 in the configuration shown in FIG. 1, that is to say with the pivoting flap 8 extending substantially perpendicularly to the axis X and the axes of the pipes 25 and 26 oriented substantially parallel to the axis X, the annular body 6 is snapped onto the neck 2 of the container (after filling of the latter) then the cover 7 and the flap 8 are pivoted towards the annular body 6 respectively by 180 ° and approximately 90 ° and joined by force insertion of the pin 33 into the recess 31. The immobilization in rotation of the end piece 4 relative to the neck 2 is guaranteed by the cooperation of shapes between the lug 14 and the cutout 13.

Après assemblage de la capsule 5, comme représenté sur la figure 3, le canal 28 se situe à l'opposé de l'ouverture latérale 15 et il est isolé de cette dernière par la jupe tubulaire 9.After assembly of the capsule 5, as shown in FIG. 3, the channel 28 is located opposite the lateral opening 15 and it is isolated from the latter by the tubular skirt 9.

La tête de distribution 1 est ainsi fermée, le clapet 34 isolé du produit, et tout départ de produit empêché.The dispensing head 1 is thus closed, the valve 34 isolated from the product, and any product departure prevented.

Lors de la première utilisation du dispositif, l'utilisateur doit entraîner en rotation la capsule 5 autour de l'axe X pour amener l'ouverture latérale 15 en regard du canal 28.When the device is used for the first time, the user must rotate the capsule 5 around the axis X to bring the lateral opening 15 opposite the channel 28.

Lors de cette rotation, les ponts de matière 17 se rompent, ce qui avertit l'utilisateur que le dispositif n'a pas été utilisé précédemment.During this rotation, the material bridges 17 break, which warns the user that the device has not been used previously.

Le départ de produit peut être provoqué par écrasement du récipient 3 lorsque ce dernier est réalisé dans une matière plastique souple ou par tout autre dispositif de mise sous pression du produit à l'intérieur du récipient. Le clapet 34 s'écarte de son siège sur le couvercle pivotant 7 sous l'effet de la pression du produit en amont dans l'orifice de distribution 29.The product departure can be caused by crushing of the container 3 when the latter is made of a flexible plastic material or by any other device for pressurizing the product inside the container. The valve 34 moves away from its seat on the pivoting cover 7 under the effect of the pressure of the product upstream in the dispensing orifice 29.

Après distribution d'une dose de produit, le clapet 34 reprend sa position de repos dans laquelle il obture l'orifice de distribution 29 grâce à son élasticité propre, le retour du clapet dans sa position de repos étant facilité le cas échéant par l'effet de succion accompagnant le retour du récipient 3 dans sa conformation initiale.After dispensing a dose of product, the valve 34 resumes its rest position in which it closes the dispensing orifice 29 thanks to its own elasticity, the return of the valve in its rest position being facilitated if necessary by the suction effect accompanying the return of the container 3 in its initial conformation.

Il est à noter que les dimensions initiales du clapet surmoulé peuvent être telles qu'un jeu est ménagé entre le clapet et son siège sur le couvercle 7 pour tenir compte du gonflement de la matière du clapet au contact du produit lors de l'utilisation.It should be noted that the initial dimensions of the overmolded valve can be such that a clearance is made between the valve and its seat on the cover 7 to take account of the swelling of the material of the valve in contact with the product during use.

On a représenté sur les figures 4 à 7 deux variantes de réalisation d'un dispositif selon l'invention pour illustrer la possibilité de réaliser grâce à l'invention des formes en contre-dépouille pour la tête de distribution.There are shown in Figures 4 to 7 two alternative embodiments of a device according to the invention to illustrate the possibility of achieving through the invention undercut shapes for the dispensing head.

On attribuera dans la suite de la description des numéros de référence identiques, simplement affectés d'un ' , pour désigner des éléments identiques ou fonctionnellement analogues à ceux de la réalisation précédente, et qui pourront par conséquent ne pas être décrits à nouveau dans le détail.In the following description, identical reference numbers will be assigned, simply assigned a ', to designate elements identical or functionally analogous to those of the previous embodiment, and which may therefore not be described again in detail. .

La tête de distribution 1' représentée sur les figures 4 et 5 diffère essentiellement de la tête de distribution 1 décrite précédemment par la géométrie du corps annulaire 6' et par l'agencement de l'embout 4' et du couvercle pivotant 7' permettant d'isoler ou de mettre en communication le canal 28' avec l'intérieur du récipient 3'. Le corps annulaire 6' comporte une paroi tubulaire 6a' sur laquelle se raccordent les ponts de matière 17' reliant l'embout 4' à la capsule 5'.The dispensing head 1 'shown in FIGS. 4 and 5 differs essentially from the dispensing head 1 described previously by the geometry of the annular body 6' and by the arrangement of the end piece 4 'and of the pivoting cover 7' allowing 'isolate or put in communication the channel 28' with the interior of the container 3 '. The annular body 6 ′ has a tubular wall 6a ′ on which the material bridges 17 ′ connecting the end piece 4 ′ to the capsule 5 ′ are connected.

La paroi 6a' est prolongée radialement vers l'extérieur à partir de son extrémité inférieure vers le haut par une paroi 6b' présentant une forme générale évasée convexe vers l'extérieur.The wall 6a 'is extended radially outwards from its lower end upwards by a wall 6b' having a generally flared shape convex towards the outside.

Le couvercle pivotant 7' et le rabat pivotant 8' sont reliés au corps annulaire 6' par des ponts de matière formant charnières 22' et 23' se raccordant respectivement à la tranche d'extrémité supérieure de la paroi 6b' en des emplacements diamétralement opposés. La paroi 6b' forme avec le couvercle pivotant 7', lorsque ce dernier est rabattu sur le corps annulaire 6', une tête de distribution en forme de boule comme représenté sur la figure 5.The pivoting cover 7 'and the pivoting flap 8' are connected to the annular body 6 'by bridges of material forming hinges 22' and 23 'connecting respectively to the upper end edge of the wall 6b' at diametrically opposite locations . The wall 6b ′ forms with the pivoting cover 7 ′, when the latter is folded over the annular body 6 ′, a distribution head in the form of a ball as shown in FIG. 5.

L'embout 4' diffère de l'embout 4 précédemment décrit par l'absence de jupe tubulaire 9 et par le fait que la jupe tubulaire 10' est traversée latéralement par un perçage formant une ouverture 15' pour le passage du produit depuis l'intérieur du récipient 3' vers le canal de distribution 28'.The end piece 4 'differs from the end piece 4 previously described by the absence of a tubular skirt 9 and by the fact that the tubular skirt 10' is crossed laterally by a hole forming an opening 15 'for the passage of the product from the interior of the container 3' to the distribution channel 28 '.

Bien entendu, la surface intérieure du col du récipient 3' dans laquelle est insérée la jupe tubulaire 10' est conformée de manière à permettre une arrivée de produit depuis l'intérieur du récipient 3' jusqu'à l'ouverture 15'.Of course, the interior surface of the neck of the container 3 ′ into which the tubular skirt 10 ′ is inserted is shaped so as to allow product to arrive from the interior of the container 3 ′ to the opening 15 ′.

Le couvercle pivotant 7' diffère principalement du couvercle 7 précédemment décrit par le fait que la tubulure 25' est ajourée latéralement à partir de sa tranche d'extrémité pour former une ouverture 35' de passage de produit entre l'ouverture latérale 15' et l'intérieur 36' de la tubulure 25'. Lorsque le couvercle 7' est rabattu sur le corps annulaire 6', la tubulure 25' s'ajuste de façon étanche à l'intérieur de la jupe tubulaire 10'.The pivoting cover 7 'differs mainly from the cover 7 previously described in that the tube 25' is perforated laterally from its end edge to form an opening 35 'for the passage of product between the lateral opening 15' and the 'interior 36' of tubing 25 '. When the cover 7 'is folded over the annular body 6', the tubing 25 'fits tightly inside the tubular skirt 10'.

On a représenté sur les figures 6 et 7 une tête de distribution 1" conforme à une deuxième variante de réalisation de la tête de distribution 1 précédemment décrite.There is shown in Figures 6 and 7 a dispensing head 1 "according to a second alternative embodiment of the dispensing head 1 previously described.

On a utilisé des numéros de référence identiques simplement affectés d'un " pour désigner des éléments identiques ou fonctionnellement analogues à ceux précédemment décrits en référence aux figures 1 à 3.Identical reference numbers have been used which are simply assigned a "to designate elements which are identical or functionally analogous to those previously described with reference to FIGS. 1 to 3.

La tête de distribution 1" diffère principalement de la tête de distribution 1' par la géométrie du corps annulaire 6". Ce dernier présente une paroi 6a" concave vers l'extérieur formant, après assemblage de la tête de distribution 1" sur le récipient 3", une gorge annulaire 37" comme représenté sur la figure 7. L'embout 4", le couvercle pivotant 7" et le rabat pivotant 8" sont identiques à ceux précédemment décrits en référence à la figure 4.The dispensing head 1 "differs mainly from the dispensing head 1 'by the geometry of the annular body 6". The latter has a wall 6a "concave towards the outside forming, after assembly of the dispensing head 1" on the container 3 ", an annular groove 37" as shown in FIG. 7. The nozzle 4 ", the pivoting cover 7 "and the pivoting flap 8" are identical to those previously described with reference to FIG. 4.

On a représenté sur la figure 8 un exemple de réalisation dans lequel deux clapets 40, 41 sont réalisés pour s'ouvrir respectivement lors de la distribution du produit et après la distribution pour la reprise d'air dans le récipient.FIG. 8 shows an exemplary embodiment in which two valves 40, 41 are made to open respectively during the dispensing of the product and after the dispensing for the return of air to the container.

Dans l'exemple décrit, les clapets 40 et 41 sont réalisés d'un seul tenant par surmoulage de matière plastique élastomère sur un rabat 42 représenté partiellement et relié par un pont de matière formant charnière au reste de la tête de distribution, à l'instar des rabats 8, 8' et 8" précédemment décrits. L'opération de surmoulage est facilitée dans la mesure où la partie qui porte les clapets, c'est-à-dire le rabat 42 s'étend à l'écart du reste de la tête de distribution lors de la fabrication de celle-ci, en étant reliée par le pont de matière 23. Elle est ainsi plus facilement accessible pour des opérations de surmoulage de matière plastique. Le rabat 42 comporte une ouverture 43 associée au clapet 41. Ce dernier est conformé pour s'engager au repos à l'intérieur de l'ouverture 43 et s'appliquer sur la surface interne du rabat 42 bordant l'ouverture 43.In the example described, the valves 40 and 41 are made in one piece by overmolding of elastomeric plastic material on a flap 42 shown partially and connected by a bridge of material forming a hinge to the rest of the dispensing head, to the like the flaps 8, 8 'and 8 "previously described. The overmolding operation is facilitated insofar as the part which carries the valves, that is to say the flap 42 extends away from the rest of the dispensing head during the manufacture thereof, being connected by the material bridge 23. It is thus more easily accessible for plastic overmolding operations. The flap 42 has an opening 43 associated with the valve 41. The latter is shaped to engage at rest inside the opening 43 and to be applied to the internal surface of the flap 42 bordering the opening 43.

Le rabat 42 comporte sur sa face interne une paroi tubulaire 44 à l'intérieur de laquelle débouche l'ouverture 43. La lame de matière élastomère dans laquelle sont réalisés les clapets 40 et 41 est fixée au rabat par une partie 45 réunissant les deux clapets. Cette partie 45 traverse un ajour 46 formé à la base de paroi tubulaire 44. Au repos, le clapet 40 repose contre un siège 47 d'un couvercle 48 à l'instar des clapets 34, 34' et 34" précédemment décrits.The flap 42 has on its internal face a tubular wall 44 inside which opens the opening 43. The blade of elastomeric material in which the valves 40 and 41 are made is fixed to the flap by a part 45 joining the two valves . This part 45 passes through an aperture 46 formed at the base of the tubular wall 44. At rest, the valve 40 rests against a seat 47 with a cover 48 like the valves 34, 34 'and 34 "previously described.

L'utilisation d'un clapet de reprise d'air permet notamment d'éviter l'apparition d'une dépression dans le récipient après la distribution du produit et un écrasement des parois de ce dernier sur elles-mêmes. En outre, puisque la reprise d'air s'effectue grâce au clapet 41, il est possible de conformer le clapet 40 de manière à ce que ce dernier s'applique de façon complètement étanche sur son siège 47 et éviter toute fuite de produit lorsque le dispositif est utilisé avec la tête de distribution en bas.The use of an air return valve makes it possible in particular to avoid the appearance of a vacuum in the container after dispensing the product and crushing of the walls of the latter on themselves. In addition, since the air intake takes place thanks to the valve 41, it is possible to conform the valve 40 so that the latter is applied in a completely sealed manner on its seat 47 and avoid any product leakage when the device is used with the dispensing head at the bottom.

On a représenté sur la figure 9 une tête de distribution 50 conforme à un cinquième exemple de réalisation de l'invention, équipant le col 51 d'un récipient.There is shown in Figure 9 a dispensing head 50 according to a fifth embodiment of the invention, fitted to the neck 51 of a container.

La tête de distribution 50 comporte un embout 52 à fixer dans le col 51 et une capsule réalisée d'un seul tenant avec l'embout 52, et constituée par la réunion d'un corps annulaire 53, d'un couvercle pivotant 54 et d'un rabat de fermeture 55. Le couvercle 54 et le rabat 55 sont reliés par des charnières film respectives 56 et 57 au corps annulaire 53. Le rabat 55 comporte un picot 58 destiné à s'engager dans un évidement adapté du couvercle 54 pour maintenir en place celui-ci comme représenté sur la figure 9.The dispensing head 50 comprises an end piece 52 to be fixed in the neck 51 and a capsule produced integrally with the end piece 52, and constituted by the union of an annular body 53, a pivoting cover 54 and d 'a closing flap 55. The cover 54 and the flap 55 are connected by respective film hinges 56 and 57 to the annular body 53. The flap 55 comprises a pin 58 intended to engage in a suitable recess of the cover 54 to maintain in place as shown in Figure 9.

Le corps annulaire 53 est relié par des ponts de matière sécables 59 à l'embout 52.The annular body 53 is connected by bridges of breakable material 59 to the end piece 52.

Après rupture de ces ponts 59, la capsule peut tourner autour de l'axe X de l'embout.After rupture of these bridges 59, the capsule can rotate around the axis X of the nozzle.

L'embout 52 comporte en partie supérieure deux jupes cylindriques concentriques 60 et 61 ménageant entre elles une gorge annulaire dans laquelle est reçue une jupe cylindrique 63 solidaire du couvercle 54. La jupe intérieure 61 est fermée à sa partie supérieure et présente une fente axiale 64.The endpiece 52 comprises in the upper part two concentric cylindrical skirts 60 and 61 forming between them an annular groove in which is received a cylindrical skirt 63 secured to the cover 54. The inner skirt 61 is closed at its upper part and has an axial slot 64 .

La jupe 63 présente également une fente axiale 65, permettant lorsqu'elle est amenée en regard de la fente 64, au produit contenu à l'intérieur du récipient de quitter celui-ci.The skirt 63 also has an axial slot 65, allowing when it is brought opposite the slot 64, the product contained inside the container to leave it.

Un clapet 66 est placé à l'extrémité supérieure de la jupe 63 pour empêcher les poussières ou le sable de pénétrer à l'intérieur du récipient, réduire le risque de fuite de produit en cas de chute du récipient par exemple et encore empêcher le désèchement du produit présent sur les parois internes du col 51 ou contenu à l'intérieur de la jupe 63 ou dans les fentes 64 et 65.A valve 66 is placed at the upper end of the skirt 63 to prevent dust or sand from entering the interior of the container, reduce the risk of product leakage if the container falls, for example, and also prevent drying out. of the product present on the internal walls of the neck 51 or contained inside the skirt 63 or in the slots 64 and 65.

Par rotation de la capsule autour de l'axe X, il est possible d'amener les fentes en regard l'une de l'autre pour la distribution du produit ou au contraire de les décaler suffisamment pour fermer la communication entre le clapet 66 et l'intérieur du flacon.By rotation of the capsule around the X axis, it is possible to bring the slots opposite one another for the distribution of the product or, on the contrary, to offset them sufficiently to close the communication between the valve 66 and inside the bottle.

Durant la rotation de la capsule, qui s'effectue après rupture des ponts 59, l'embout 52 est bloqué en rotation sur le col 51 par exemple par engagement d'un relief externe 67 du col 51 dans un évidement 68 de forme complémentaire de l'embout.During the rotation of the capsule, which takes place after the bridges 59 have broken, the endpiece 52 is blocked in rotation on the neck 51 for example by engagement of an external relief 67 of the neck 51 in a recess 68 of complementary shape. the mouthpiece.

Le corps annulaire 53 de la capsule est maintenu axialement sur le col par encliquetage dans une gorge 69 de ce dernier.The annular body 53 of the capsule is held axially on the neck by snapping into a groove 69 of the latter.

Le clapet 66 est venu de moulage d'un seul tenant avec le couvercle 54. Il est relié au reste du couvercle par un pont de matière 70 lui permettant de se soulever sous l'action du produit lors de la distribution. Leclapet présente en vue de dessus comme représenté sur la figure 10 une forme générale en Ω et son bord libre ménage avec le bord adjacent du couvercle un interstice g compris entre 0,1 et 0,2 mm. Cet interstice permet la reprise d'air.The valve 66 is molded integrally with the cover 54. It is connected to the rest of the cover by a bridge of material 70 allowing it to be lifted under the action of the product during distribution. Leclapet presents in top view as shown in Figure 10 a general shape in Ω and its free edge forms with the adjacent edge of the cover a gap g between 0.1 and 0.2 mm. This interstice allows the air intake.

Dans une variante de réalisation non représentée, le clapet 66 est réalisé dans la même matière que le couvercle mais avec une couleur différente, par moulage par bi-injection de matière. Il peut également être réalisé par bi-injection dans une matière plus souple que celle utilisée pour mouler le reste du couvercle. Enfin, le clapet peut être réalisé à part et rapporté et fixé ensuite par tout moyen connu sur le couvercle.In an alternative embodiment not shown, the valve 66 is made of the same material as the cover but with a different color, by molding by bi-injection of material. he can also be made by bi-injection in a softer material than that used to mold the rest of the cover. Finally, the valve can be produced separately and attached and then fixed by any known means on the cover.

Finalement, l'invention permet de réaliser des formes de têtes de distribution présentant des contre-dépouilles et autorise une plus grande liberté dans le choix de l'esthétique générale du conditionnement.Finally, the invention makes it possible to produce shapes of dispensing heads having undercuts and allows greater freedom in the choice of the general aesthetics of the packaging.

La fabrication de la tête de distribution est rendue plus facile grâce à l'invention, notamment par le fait qu'elle permet de réaliser sans trop de difficultés le ou les clapet(s).The manufacture of the dispensing head is made easier thanks to the invention, in particular by the fact that it makes it possible to produce the valve (s) without too much difficulty.

L'invention permet également de réduire les possibilités d'accès à l'intérieur de la capsule de corps étrangers tels que du sable.The invention also makes it possible to reduce the possibilities of access to the interior of the capsule of foreign bodies such as sand.

Les ponts de matière 17, 17',17" ou 59 reliant l'embout et la capsule, aptes à maintenir cette dernière dans une position dans laquelle elle isole le canal de distribution de l'intérieur du récipient, permettent d'éviter que pendant le stockage, avant première utilisation, le clapet en matériau élastomère ne soit en contact avec le produit et le gonflement de la matière du clapet.The material bridges 17, 17 ', 17 "or 59 connecting the endpiece and the capsule, capable of maintaining the latter in a position in which it isolates the distribution channel from the interior of the container, make it possible to avoid that during storage, before first use, the valve made of elastomeric material is not in contact with the product and the swelling of the material of the valve.

L'invention permet avantageusement de réaliser des formes à contre-dépouille pour la tête de distribution avec un minimum de matière, la coque 24 de la capsule pouvant être de faible épaisseur.The invention advantageously makes it possible to produce undercut shapes for the dispensing head with a minimum of material, the shell 24 of the capsule being able to be thin.

Les figures 1 à 10 correspondent à des exemples de réalisations comportant un embout à fixer dans une embouchure d'un récipient.Figures 1 to 10 correspond to exemplary embodiments comprising a nozzle to be fixed in a mouth of a container.

On ne sort pas du cadre de l'invention en fixant l'embout sur une pompe ou sur une valve équipant un récipient, auquel cas la tête de distribution peut servir également de bouton-poussoir.It is not going beyond the scope of the invention to fix the end piece on a pump or on a valve fitted to a container, in which case the dispensing head can also serve as a push button.

La reprise d'air peut bien entendu s'effectuer par une fermeture non complètement étanche de l'orifice de distribution de produit en l'absence de distribution de produit, ou lors de la reprise d'air, ou par un clapet de reprise d'air non solidaire du clapet s'ouvrant sous l'effet de la pression du produit à distribuer.The air intake can of course be carried out by a not completely sealed closure of the product dispensing orifice in the absence of product dispensing, or during the air intake, or by a return valve d air not attached to the valve opening under the effect of the pressure of the product to be dispensed.

On peut encore modifier les parties coopérantes de l'embout et de la capsule permettant d'obtenir l'ouverture et la fermeture de la tête de distribution.It is also possible to modify the cooperating parts of the end piece and of the capsule, making it possible to obtain the opening and closing of the dispensing head.
