Description

La présente invention concerne un distributeur de produit fluide, liquide ou pulvérulent, et plus particulièrement une tête de distribution de produit fluide faisant partie intégrante d'un distributeur de produit fluide. La tête peut intégrer un poussoir sur lequel l'utilisateur peut appuyer pour actionner le distributeur. En variante, la tête de distribution peut être dissociée du poussoir d'actionnement. Un tel distributeur équipé d'une telle tête de distribution trouve une application privilégiée dans les domaines de la cosmétique, de la pharmacie ou encore de la parfumerie.The present invention relates to a fluid dispenser, liquid or powder, and more particularly to a fluid dispenser head integral with a fluid dispenser. The head can incorporate a pusher on which the user can press to operate the dispenser. Alternatively, the dispensing head can be dissociated from the actuating pusher. Such a dispenser equipped with such a dispensing head finds a privileged application in the fields of cosmetics, pharmaceuticals or even perfumery.

La tête de distribution est destinée à coopérer directement ou indirectement avec un organe de distribution tel qu'une pompe montée sur un réservoir de produit fluide formé par un récipient. La tête comprend généralement un conduit de produit fluide définissant une extrémité d'entrée et une extrémité de sortie, l'extrémité d'entrée étant reliée à une sortie de la pompe et l'extrémité de sortie du conduit définit un orifice de distribution au niveau duquel l'utilisateur peut prélever le produit fluide distribué. La présente invention s'appliquera particulièrement aux têtes comprenant des moyens d'obturation destinés à obturer sélectivement l'orifice de distribution, afin de protéger le produit fluide contenu à l'intérieur du conduit de produit fluide. On évite ainsi toute détérioration du produit par oxydation ou dessèchement. En général, les moyens d'obturation comprennent un organe d'obturation déplaçable entre une position d'obturation dans laquelle l'organe d'obturation obture l'orifice de distribution à une position d'ouverture dans laquelle le produit fluide issu de l'organe de distribution peut s'écouler à travers le conduit et l'orifice de distribution.The dispensing head is intended to cooperate directly or indirectly with a dispensing member such as a pump mounted on a fluid reservoir formed by a container. The head generally comprises a fluid product duct defining an inlet end and an outlet end, the inlet end being connected to an outlet of the pump and the outlet end of the duct defining a distribution orifice at the inlet end. from which the user can take the dispensed fluid. The present invention will particularly apply to heads comprising closure means for selectively closing the dispensing orifice, in order to protect the fluid contained within the fluid conduit. This avoids any deterioration of the product by oxidation or drying. In general, the closure means comprise a shutter member movable between a closed position in which the closure member closes the dispensing orifice at an open position in which the fluid product from the dispensing member may flow through the conduit and the dispensing orifice.

Il existe déjà dans l'art antérieur de nombreux types de moyens d'obturation permettant d'obturer l'orifice de distribution d'une tête de distribution. Ces divers moyens d'obturation diffèrent les uns des autres par le mode de déplacement de l'organe d'obturation par rapport à l'orifice de distribution à obturer. Un premier type de moyens d'obturation met en oeuvre des organes d'obturation déplaçables par le produit fluide sous pression. Ainsi, lors de l'actionnement du distributeur, le produit fluide refoulé sous pression agit directement ou indirectement sur l'organe d'obturation pour le déplacer de sa position d'obturation et ainsi dégager un passage de sortie pour le produit fluide sous pression. Il existe d'autre part un autre type de moyens d'obturation dont l'organe d'obturation est déplaçable par une manipulation préalable à l'actionnement du distributeur. La présente invention s'appliquera plus particulièrement à ce second type de moyens d'obturation actionnable indépendamment de l'actionnement du distributeur. On connaît déjà dans l'art antérieur de tels moyens d'obturation. Des moyens d'obturation très simples sont constitués par ceux où l'organe d'obturation obture l'orifice de distribution de l'extérieur. Dans ce cas, l'utilisateur devra retirer l'organe d'obturation de l'orifice de distribution en agissant directement ou indirectement sur l'organe d'obturation. Il existe d'autre part des moyens d'obturation dont l'organe d'obturation agit de l'intérieur de la tête de distribution. Dans ce cas, l'utilisateur devra agir sur des moyens d'actionnement permettant de déplacer l'organe d'obturation à l'intérieur de la tête de distribution. En général, les moyens d'actionnement ont pour effet de générer un déplacement translatif de l'organe d'obturation à l'intérieur de la tête de distribution.Many types of closure means already exist in the prior art for closing the distribution orifice of a dispensing head. These various closure means differ from one another by the mode of movement of the closure member relative to the dispensing orifice to be closed. A first type of closure means implements shutter members displaceable by the fluid under pressure. Thus, during actuation of the dispenser, the fluid product discharged under pressure acts directly or indirectly on the closure member to move it from its closed position and thus clear an outlet passage for the fluid under pressure. On the other hand there is another type of closure means whose shutter member is movable by manipulation prior to actuation of the dispenser. The present invention will apply more particularly to this second type of shutter means operable independently of the actuation of the dispenser. Already known in the prior art such sealing means. Very simple sealing means are constituted by those where the closure member closes the dispensing orifice from the outside. In this case, the user will have to remove the closure member from the dispensing orifice by acting directly or indirectly on the closure member. On the other hand there are closure means whose shutter member acts from inside the dispensing head. In this case, the user must act on actuating means for moving the shutter member inside the dispensing head. In general, the actuating means have the effect of generating a translational movement of the shutter member inside the dispensing head.

Le document EP 1 310 437 divulge une tête de distribution de produit fluide selon le préambule de la revendication 1.The document EP 1 310 437 discloses a fluid dispenser head according to the preamble of claim 1.

La présente invention a pour but de définir un autre type de mode d'actionnement pour un organe d'obturation faisant partie intégrante de moyens d'obturation intégrés dans une tête de distribution d'un distributeur de produit fluide.The present invention aims to define another type of actuation mode for a closure member integral with sealing means integrated in a dispensing head of a fluid dispenser.

Pour ce faire, la présente invention propose que la tête comprenne une partie fixe solidaire en rotation de l'organe de distribution et une partie rotative déplaçable en rotation par rapport à la partie fixe, ladite tête comprenant des moyens de déplacement aptes à déplacer l'organe d'obturation entre les positions d'obturation et d'ouverture lors de la rotation de la partie rotative par rapport à la partie fixe. Les moyens d'obturation sont de préférence logés à l'intérieur de la partie rotative de la tête. Ainsi, l'organe d'obturation est non seulement entraîné en rotation par la partie rotative, mais est encore entraîné en translation à l'intérieur de la partie rotative entre les positions d'obturation et d'ouverture. Ainsi, l'organe d'obturation effectue un mouvement complexe qui s'apparente à un segment de spirale concentrique.To do this, the present invention proposes that the head comprises a fixed part that is rotatably connected to the dispensing member and a rotatable part that is displaceable in rotation with respect to the fixed part, said head comprising displacement means capable of displacing the shutter member between the shutter and opening positions during rotation of the rotating part relative to the fixed part. The sealing means are preferably housed inside the rotating part of the head. Thus, the shutter member is not only rotated by the rotating part, but is still driven in translation to the inside of the rotating part between the closing and opening positions. Thus, the shutter member performs a complex movement that is similar to a concentric spiral segment.

Avantageusement, les moyens de déplacement sont formés par la partie fixe. D'autre part, l'orifice de distribution peut être formé par la partie rotative.Advantageously, the displacement means are formed by the fixed part. On the other hand, the dispensing orifice may be formed by the rotating part.

Selon un autre aspect de l'invention, le conduit est partiellement formé par la partie rotative et partiellement formé par la partie fixe. Avantageusement, le conduit comprend une section radiale formée par la partie rotative et une section axiale formée par la partie fixe, la section axiale se raccordant à la section radiale. De préférence, les moyens d'obturation sont logés dans la section radiale. D'autre part, les moyens de déplacement peuvent s'étendre dans la section radiale. En variante, le conduit peut être intégralement formé par la partie rotative. En tout cas, les moyens d'obturation, et plus particulièrement l'organe d'obturation est logé à l'intérieur du conduit formé par la partie rotative.According to another aspect of the invention, the duct is partially formed by the rotating part and partially formed by the fixed part. Advantageously, the duct comprises a radial section formed by the rotating part and an axial section formed by the fixed part, the axial section being connected to the radial section. Preferably, the sealing means are housed in the radial section. On the other hand, the displacement means can extend in the radial section. Alternatively, the conduit may be integrally formed by the rotatable portion. In any case, the sealing means, and more particularly the closure member is housed inside the conduit formed by the rotating part.

Selon une autre caractéristique intéressante de l'invention, la partie rotative définit un axe de rotation, les moyens de déplacement étant excentrés par rapport à cet axe.According to another advantageous characteristic of the invention, the rotating part defines an axis of rotation, the displacement means being eccentric with respect to this axis.

Selon un autre aspect, les moyens d'obturation comprennent un élément de liaison et un élément d'ancrage, ledit élément de liaison reliant l'organe d'obturation à l'élément d'ancrage. Avantageusement, les moyens de déplacement sont en prise avec l'élément d'ancrage pour exercer une traction sur l'organe d'obturation par l'intermédiaire de l'élément de liaison. En variante, les moyens de déplacement sont en prise avec l'élément de liaison pour générer une déformation de l'élément de liaison.In another aspect, the closure means comprise a connecting element and an anchoring element, said connecting element connecting the closure member to the anchoring element. Advantageously, the displacement means are engaged with the anchoring element to exert traction on the closure member via the connecting element. In a variant, the displacement means are engaged with the connecting element to generate a deformation of the connecting element.

Selon encore un autre aspect, l'élément de liaison sollicite l'organe d'obturation en contact étanche dans l'orifice de distribution en position d'obturation.According to yet another aspect, the connecting element biases the closure member in sealed contact in the dispensing orifice in the closed position.

Selon une autre caractéristique intéressante de l'invention, la tête de distribution de produit fluide comprend en outre un poussoir sur lequel on appuie pour actionner l'organe de distribution et un système de verrouillage rotatif déplaçable entre une position verrouillée dans laquelle la tête est inopérante par appui sur le poussoir et une position déverrouillée dans laquelle la tête est opérante par appui sur le poussoir, les positions verrouillée et d'obturation étant confondues et les positions déverrouillée et d'ouverture étant confondues. Ainsi, l'utilisateur ne s'aperçoit même pas de la présence ni de l'action des moyens d'obturation dont l'actionnement est confondu avec celui du système de verrouillage rotatif. Il faut savoir qu'un tel système de verrouillage rotatif est déjà connu de l'art antérieur, et notamment du document FR-2 789 057 . L'avantage de l'association des moyens d'obturation de l'invention avec un tel système de verrouillage réside dans le fait que l'actionnement du système de verrouillage entraîne automatiquement l'actionnement des moyens d'obturation sans besoin d'opération supplémentaire.According to another advantageous characteristic of the invention, the fluid dispensing head further comprises a pusher on which is pressed to actuate the dispensing member and a rotatable locking system movable between a locked position in which the head is inoperative by pressing the pusher and an unlocked position in which the head is operative by pressing the pusher, the locked and closed positions being merged and the unlocked and opening positions being merged. Thus, the user does not even notice the presence or action of the shutter means whose actuation is coincident with that of the rotary locking system. It should be known that such a rotary locking system is already known from the prior art, and in particular the document FR-2 789 057 . The advantage of the combination of the closure means of the invention with such a locking system lies in the fact that the actuation of the locking system automatically causes the actuation of the shutter means without the need for additional operation .

L'invention a également pour objet un distributeur de produit fluide comprenant un réservoir de produit fluide, un organe de distribution tel qu'une pompe et une tête de distribution telle que définie ci-dessus.The invention also relates to a fluid dispenser comprising a fluid reservoir, a dispensing member such as a pump and a dispensing head as defined above.

Nous nous référerons tout d'abord à la figure 1 pour décrire en détail les divers éléments constitutifs du distributeur de produit fluide selon le premier mode de réalisation de l'invention. Toutefois, le second mode de réalisation des figures 7 et 8 ne diffère de celui de la figure 1 pratiquement qu'au niveau des moyens d'obturation et des moyens de déplacement pour déplacer ces moyens d'obturation. Tous les autres éléments constitutifs peuvent être identiques.We will refer first of all to the figure 1 to describe in detail the various constituent elements of the fluid dispenser according to the first embodiment of the invention. However, the second embodiment of the Figures 7 and 8 does not differ from that of the figure 1 practically at the level of the closure means and displacement means for moving these closure means. All other constituent elements can be identical.

Le distributeur comprend un récipient 1 définissant un fût cylindrique 11 ayant une paroi interne de coulissement 111. A son extrémité supérieure, le fût 11 se prolonge par un épaulement 12 qui s'étend vers l'intérieur. Sur sa périphérie interne, l'épaulement 12 se raccorde à un col 13 définissant intérieurement une ouverture 130. L'extrémité supérieure du col 13 est pourvue d'un renforcement définissant un profil de fixation 14, qui peut être un profil d'encliquetage. A son extrémité inférieure, le fût 11 définit également un profil de réception 15 pour un fond rapporté 2. Un piston-suiveur 3 est monté coulissant à l'intérieur du fût 11. Ce piston-suiveur 3 comprend une paroi de fond 32 bordée par une lèvre d'étanchéité 31 adaptée à se déplacer en contact coulissant contre la paroi interne 111 définie par le fût 11. La paroi de fond 32, le fût 11, l'épaulement 12 et le col 13 définissent ensemble un volume interne qui sert de réservoir de produit fluide 10. Il s'agit d'un réservoir de volume variable, étant donné que le piston-suiveur 3 va se déplacer dans le fût 11 en direction de l'ouverture 130 à mesure que du produit fluide est extrait du réservoir. Il s'agit là d'un type de réservoir particulier, mais il fait bien comprendre que d'autres types de réservoirs à volume constant ou variable peuvent être utilisés pour mettre en oeuvre la présente invention. Une poche souple constitue un autre type de réservoir de volume variable. En revanche, un flacon rigide indéformable constitue un réservoir de volume constant.The dispenser comprises a container 1 defining a cylindrical barrel 11 having an inner sliding wall 111. At its upper end, the barrel 11 is extended by a shoulder 12 which extends inwardly. On its inner periphery, the shoulder 12 connects to a neck 13 internally defining an opening 130. The upper end of the neck 13 is provided with a reinforcement defining a fastening profile 14, which may be a snap profile. At its lower end, the barrel 11 also defines a receiving profile 15 for an attached bottom 2. A follower piston 3 is slidably mounted inside the barrel 11. This follower piston 3 comprises a bottom wall 32 bordered by a sealing lip 31 adapted to move in sliding contact against the inner wall 111 defined by the barrel 11. The bottom wall 32, the barrel 11, the shoulder 12 and the neck 13 together define an internal volume which serves as fluid reservoir 10. It is a variable volume reservoir, since the follower piston 3 will move in the barrel 11 towards the opening 130 as fluid is extracted from the reservoir . This is a particular type of tank, but it is clear that other types of constant or variable volume tanks can be used to implement the present invention. A flexible pouch is another type of variable volume tank. On the other hand, a rigid non-deformable bottle constitutes a reservoir of constant volume.

Le distributeur comprend également un organe de distribution 4, qui est ici une pompe. La pompe 4 comprend un corps de pompe 41 définissant une collerette 45 qui fait saillie radialement vers l'extérieur. Cette collerette est destinée à venir en appui sur l'extrémité supérieure du col 13, avec l'interposition éventuelle d'un joint de col 45. La pompe 4 comprend également une tige d'actionnement 43 qui est déplaçable axialement en va-et-vient à l'intérieur du corps de pompe 41. La tige d'actionnement 43 définit ici un canal interne de refoulement qui permet au produit fluide mis sous pression à l'intérieur de la pompe d'être refoulé à travers le canal lors de l'enfoncement de la tige d'actionnement 43 dans le corps de pompe 41. La pompe 4 est disposée sur le récipient 1 avec sa collerette 45 en appui sur le bord supérieur du col 13 de sorte que la majeure partie de son corps 41 s'étend à l'intérieur de l'ouverture 130 du col 13 avec sa tige d'actionnement 43 qui fait saillie hors du col 13.The dispenser also comprises a dispensing member 4, which is here a pump. The pump 4 comprises a pump body 41 defining a flange 45 which projects radially outwards. This flange is intended to bear on the upper end of the neck 13, with the possible interposition of a neck seal 45. The pump 4 also comprises an actuating rod 43 which is axially movable in va-et- The actuating rod 43 here defines an internal discharge channel which allows the fluid product pressurized inside the pump to be forced through the channel during the operation of the pump. depression of the actuating rod 43 in the pump body 41. The pump 4 is disposed on the container 1 with its flange 45 resting on the upper edge of the neck 13 so that the majority of its body 41 s' extends inside the opening 130 of the neck 13 with its actuating rod 43 which projects out of the neck 13.

L'organe de distribution 4 présente un axe de symétrie et de révolution XX qui est celui du distributeur dans son ensemble. De préférence, le récipient 1 présente également un axe de symétrie et de révolution qui est confondu avec l'axe XX une fois l'organe de distribution 4 monté sur le col 13 du récipient.The dispensing member 4 has an axis of symmetry and revolution XX which is that of the distributor as a whole. Preferably, the container 1 also has an axis of symmetry and revolution which is coincident with the axis XX once the dispensing member 4 mounted on the neck 13 of the container.

Le distributeur comprend d'autre part un organe de fixation 5 dont la fonction première est de fixer l'organe de distribution 4 sur le récipient 1. L'organe de fixation 5 comprend un logement de réception 52 pour la collerette 42 de la pompe 4 : de préférence, la collerette 42 est maintenue par encliquetage à l'intérieur du logement 52. L'organe de fixation 5 comprend d'autre part une jupe de fixation 54 qui est en prise de fixation, avantageusement par encliquetage, avec le profil de fixation 14 formé par le col 13. La combinaison du logement 52 et de la jupe 54 permet de fixer de manière stable la pompe 4 dans l'ouverture 130 du col 13. L'organe de fixation 5 peut également comprendre une coupole 51 qui vient en prise avec sa périphérie extérieure avec l'épaulement 12 du récipient 1. L'organe de fixation 5 forme également une douille de guidage axiale 56 qui s'étend autour de la partie supérieure du corps de pompe 41. Cette douille de guidage 56 est formée extérieurement avec une série de nervures et de rainures 561 qui s'étendent longitudinalement et verticalement. L'organe de fixation 5 comprend également un manchon de verrouillage 57 dont la paroi interne forme ici deux rainures 571, comme on peut le voir sur les figures. Le manchon de verrouillage 57 forme également deux épaulements 570 à proximité de son extrémité supérieure libre. Les épaulements 570 sont orientés vers l'intérieur et communiquent à une de leurs extrémités avec les rainures 571. L'épaisseur de la paroi du manchon au-dessus de l'épaulement 570 est réduite.The distributor further comprises a fastener 5 whose primary function is to fix the dispenser member 4 on the container 1. The fastener 5 comprises a receiving housing 52 for the flange 42 of the pump 4 preferably, the flange 42 is held snap-fitting inside the housing 52. The fixing member 5 further comprises a fastening skirt 54 which is in engagement with the fastening profile, advantageously by snap-fastening, with the fastening profile. fixation 14 formed by the neck 13. The combination of the housing 52 and the skirt 54 stably fixes the pump 4 in the opening 130 of the neck 13. The fastener 5 may also include a cupola 51 which comes in engagement with its outer periphery with the shoulder 12 of the container 1. The fastener 5 also forms an axial guide sleeve 56 which extends around the upper part of the pump body 41. Guide bush 56 is formed externally with a series of ribs and grooves 561 which extend longitudinally and vertically. The fastener 5 also comprises a locking sleeve 57 whose inner wall here forms two grooves 571, as can be seen in the figures. The locking sleeve 57 also forms two shoulders 570 near its free upper end. The shoulders 570 are inwardly oriented and communicate at one of their ends with the grooves 571. The thickness of the wall of the sleeve above the shoulder 570 is reduced.

La tête de distribution de produit fluide de l'invention comprend ici quatre pièces constitutives, à savoir un insert 6, un corps 7, une buse 8 et un obturateur 9. L'organe de fixation 5 peut être considéré comme faisant partie intégrante de la tête de distribution, car il coopère avec la tête pour remplir certaines fonctions, comme on le verra ci-après.The fluid dispensing head of the invention here comprises four constituent parts, namely an insert 6, a body 7, a nozzle 8 and a shutter 9. The fastener 5 can be considered as an integral part of the invention. distribution head, because it cooperates with the head to perform certain functions, as will be seen below.

L'insert 6 comprend un manchon de raccordement 64 à l'intérieur duquel est engagée l'extrémité supérieure libre de la tige d'actionnement 43. Le manchon de raccordement 64 se prolonge par une tubulure 611 qui définit intérieurement une section de conduit axiale 61. Cette section 61 s'étend donc dans le prolongement du canal interne défini à l'intérieur de la tige d'actionnement 43. Par conséquent, le produit fluide issu de la tige d'actionnement 43 peut s'écouler dans la section de conduit 61. La tubulure 611 est également pourvue d'un ergot 69 qui fait saillie au-delà de la section de conduit axiale 61. Nous verrons ci-après que cet ergot 69 a une fonction de moyen de déplacement de l'obturateur 9. Nous verrons également en référence aux figures 4 et 5 que cet ergot peut opérer d'une manière différente pour déplacer l'obturateur 9'. L'insert 6 définit également une bride annulaire 67 qui s'étend vers l'extérieur à partir de l'extrémité supérieure du manchon de raccordement 64. Cette bride 67 se prolonge sur sa périphérie extérieure par une jupe de guidage 65 qui s'étend vers le bas. Cette jupe de guidage 65 présente sur sa paroi extérieure des moyens d'encliquetage 653 qui peuvent se présenter sous la forme d'un cordon d'encliquetage continu ou de plusieurs profils d'encliquetage discrets. La jupe de guidage 65 forme également une série de nervures 652 et de rainures 651 qui s'étendent longitudinalement et verticalement au niveau de sa paroi interne. La série de nervures et de rainures est en prise avec la série complémentaire de rainures 562 et de nervures 561 formée par la douille de guidage 56 de l'organe de fixation 5. Plus précisément, la jupe de guidage 65 s'étend de manière concentrique autour de la douille de guidage 56 avec les rainures de l'une imbriquées dans les nervures de l'autre et inversement. L'engagement des rainures et des nervures de la jupe et de la douille permet un déplacement axial de l'insert 6 par rapport à l'organe de fixation 5 en interdisant tout déplacement rotatif entre elles. Ainsi, en appuyant sur l'insert 6, on déplace axialement la tige d'actionnement 43 dans le corps de pompe 41, ce qui a pour conséquence d'abaisser la jupe de guidage 65 autour de la douille de guidage 56. L'imbrication des rainures et des nervures de la douille et de la jupe remplit ainsi un rôle de moyen de blocage en rotation et de moyen de guidage en translation axiale le long de l'axe XX. L'insert 6 constitue ainsi une partie fixe de la tête de distribution par rapport à l'organe de fixation 5, au récipient 1 et/ou à l'organe de distribution 4. Bien entendu, l'adjectif « fixe » doit être compris comme empêchant la rotation de l'insert 6 tout en permettant son déplacement axial.The insert 6 comprises a connecting sleeve 64 inside which is engaged the free upper end of the actuating rod 43. The connecting sleeve 64 is extended by a pipe 611 which internally defines an axial duct section 61 This section 61 thus extends in the extension of the internal channel defined inside the actuating rod 43. Consequently, the fluid product coming from the actuating rod 43 can flow into the duct section. 61. The tubing 611 is also provided with a lug 69 which protrudes beyond the axial duct section 61. We shall see below that this lug 69 has a function of means of displacement of the shutter 9. We will also see with reference to Figures 4 and 5 that this lug can operate in a different way to move the shutter 9 '. The insert 6 also defines an annular flange 67 which extends outwardly from the upper end of the connecting sleeve 64. This flange 67 is extended on its outer periphery by a guide skirt 65 which extends down. This guide skirt 65 has on its outer wall latching means 653 which may be in the form of a continuous snap bead or several discrete snap profiles. The guide skirt 65 also forms a series of ribs 652 and grooves 651 which extend longitudinally and vertically at its inner wall. The series of ribs and grooves is engaged with the complementary series of grooves 562 and ribs 561 formed by the guide sleeve 56 of the fastener 5. More specifically, the guide skirt 65 concentrically extends around the guide sleeve 56 with the grooves of one nested in the ribs of the other and vice versa. The engagement of the grooves and ribs of the skirt and the bushing allows an axial displacement of the insert 6 relative to the fastener 5 by preventing any rotational movement between them. Thus, by pressing on the insert 6, the actuating rod 43 is moved axially in the pump body 41, which has the effect of lowering the guide skirt 65 around the guide sleeve 56. The interlocking grooves and ribs of the bushing and the skirt thus fulfill a role of rotation locking means and axial translation guide means along the axis XX. The insert 6 thus constitutes a fixed part of the dispensing head with respect to the fixing member 5, to the container 1 and / or to the dispensing member 4. Of course, the adjective "fixed" must be understood as preventing the rotation of the insert 6 while allowing its axial displacement.

Le corps 7 définit extérieurement une enveloppe 71 et une surface de poussoir supérieure 72. Le corps 7 définit également un embout 74 à l'intérieur duquel s'étend une section de conduit radiale 73. Cette section 73 s'étend en dessous de la surface de poussoir 72. La section radiale 73 débouche axialement et centralement vers le bas au niveau d'une manchette 76 en prise étanche rotative autour de la tubulure 611. Ainsi, la section de conduit axiale 61 est située à l'intérieur de la manchette 76, et la section axiale 61 communique directement avec la section radiale 73. De ce fait, le produit fluide issu de la tige d'actionnement 43 peut s'écouler à travers la section axiale 61 dans la section radiale 73. L'ergot 69 s'étend à l'intérieur de la section radiale 73. Il faut remarquer que l'ergot 69 est situé de manière excentrée par rapport à l'axe XX. Ceci est clairement visible sur la figure 1. Le corps 7 définit également une jupe de verrouillage 75 qui s'étend vers le bas. La jupe 75 définit au niveau de sa paroi interne un profil de fixation 752 qui agit de préférence par encliquetage avec le profil correspondant 653 formé par la jupe de guidage 65. Le profil 752 est engagé en dessous du profil 653 de manière à maintenir l'insert 6 à l'intérieur de la jupe de verrouillage 75. Toutefois, l'insert 6 peut librement tourner à l'intérieur de la jupe de verrouillage 75. La jupe de verrouillage est en outre pourvue au niveau de sa paroi externe de deux nervures verticales 751. Sur les figures 1 et 2a, l'extrémité inférieure libre des nervures est en butée sur l'épaulement 570 formé à l'extrémité supérieure intérieure du manchon de verrouillage 57. De ce fait, il n'est pas possible de déplacer le corps 7 axialement par rapport à l'organe de fixation 5 en exerçant une poussée sur la surface de poussoir 72. En revanche, il est possible d'entraîner le corps 7 en rotation autour de l'axe XX en laissant l'insert 6 et l'organe de fixation 5 fixes en rotation. Le corps 7 peut ainsi être entraîné en rotation sur un quart de tour par exemple. Pendant cette rotation limitée, les extrémités inférieures des nervures vont glisser sur les épaulements respectifs. La figure 3a représente le distributeur après cette rotation d'un quart de tour. On voit alors que les nervures formées à l'extérieur de la jupe de verrouillage 75 sont situées à l'aplomb des rainures 571 formée au niveau de la paroi interne du manchon de verrouillage 57. La jupe de verrouillage 75 peut alors être déplacée vers le bas à l'intérieur du manchon de verrouillage 57. La coopération du manchon 57 avec la jupe 75 constitue des moyens ou un système de verrouillage rotatif déplaçable entre une position verrouillée et une position déverrouillée. Dans la position verrouillée, telle que représentée sur les figures 1 et 2a, le corps 7 ne peut pas être déplacé axialement par appui sur la surface de poussée 72, alors que dans la position déverrouillée représentée sur la figure 2a, un appui sur la surface de poussoir 72 a pour effet d'abaisser le corps 7 en entraînant l'insert 6 et la tige d'actionnement 43 dans le corps de pompe 41. Les figures 4a, 4b et 4c, ainsi que la figure 2b aident à la compréhension des positions mutuelles des différents éléments dans cette position verrouillée. Dans la position déverrouillée représentée sur la figure 3a, la pompe 4 est de ce fait actionnable. Les figures 5a, 5b et 5c, ainsi que la figure 3b aident à la compréhension des positions mutuelles des différents éléments dans cette position d'actionnement. Le système de verrouillage constitué par le manchon et la jupe de verrouillage ne constitue qu'un exemple non limitatif de moyen de verrouillage. Bien entendu, on peut utiliser n'importe quel autre système de verrouillage rotatif dans le cadre de la présente invention sans pour autant en limiter sa portée.The body 7 externally defines an envelope 71 and an upper pusher surface 72. The body 7 also defines a tip 74 within which extends a radial conduit section 73. This section 73 extends below the surface The radial section 73 opens axially and centrally downwardly at a sleeve 76 in rotary sealing engagement about the tubing 611. Thus, the axial duct section 61 is located inside the cuff 76. , and the axial section 61 communicates directly with the radial section 73. As a result, the fluid product from the actuating rod 43 can flow through the axial section 61 in the radial section 73. The lug 69 s extends within the radial section 73. It should be noted that the lug 69 is located eccentrically with respect to the axis XX. This is clearly visible on the figure 1 . The body 7 also defines a locking skirt 75 which extends downwards. The skirt 75 defines at its wall internal a fastening profile 752 which preferably acts by snapping with the corresponding profile 653 formed by the guide skirt 65. The profile 752 is engaged below the profile 653 so as to maintain the insert 6 inside the skirt However, the insert 6 can freely rotate inside the locking skirt 75. The locking skirt is further provided at its outer wall with two vertical ribs 751. figures 1 and 2a , the free lower end of the ribs abuts on the shoulder 570 formed at the upper inner end of the locking sleeve 57. As a result, it is not possible to move the body 7 axially relative to the fixing member 5 by exerting a thrust on the pusher surface 72. On the other hand, it is possible to drive the body 7 in rotation around the axis XX while leaving the insert 6 and the fixing member 5 fixed in rotation. The body 7 can thus be rotated over a quarter turn, for example. During this limited rotation, the lower ends of the ribs will slide on the respective shoulders. The figure 3a represents the distributor after this rotation of a quarter turn. It can be seen that the ribs formed outside of the locking skirt 75 are situated in line with the grooves 571 formed at the inner wall of the locking sleeve 57. The locking skirt 75 can then be moved towards the The engagement of the sleeve 57 with the skirt 75 provides means or a rotatable locking system movable between a locked position and an unlocked position. In the locked position, as shown on the figures 1 and 2a , the body 7 can not be displaced axially by pressing on the thrust surface 72, whereas in the unlocked position shown on the figure 2a , a pressing on the pusher surface 72 has the effect of lowering the body 7 by driving the insert 6 and the actuating rod 43 into the pump body 41. Figures 4a, 4b and 4c , as well as figure 2b help to understand the mutual positions of the different elements in this locked position. In the unlocked position shown on the figure 3a , the pump 4 is thereby actuable. The Figures 5a, 5b and 5c , as well as figure 3b help to understand the mutual positions of the different elements in this actuating position. The locking system constituted by the sleeve and the locking skirt is only a non-limiting example of locking means. Of course, any other rotary locking system can be used in the context of the present invention without limiting its scope.

La buse 8 comprend une enveloppe extérieure 81 en prise avec l'enveloppe extérieure 71 et la surface de poussoir 72 du corps 7. La buse 8 comprend également une tubulure de distribution 82 engagée de manière étanche à l'intérieur de l'embout 74. La tubulure 82 s'étend à l'intérieur de l'enveloppe 81 et débouche tous deux au niveau d'un orifice de distribution 83. Ainsi, la tubulure 82 définit une partie de la section de conduit radiale 73 avec l'orifice de distribution 83 qui définit l'extrémité de sortie de cette section 73. A son extrémité opposée, la section axiale 61 forme l'entrée du conduit. Le produit fluide refoulé à travers la tige d'actionnement 43 peut ainsi s'écouler à travers la section 71, la section 73 et l'orifice de distribution 83 où il peut être récupéré par l'utilisateur. La distribution du produit fluide peut être réalisée sous forme pulvérisée ou encore sous la forme d'une noisette de produit fluide.The nozzle 8 comprises an outer casing 81 in engagement with the outer casing 71 and the pusher surface 72 of the body 7. The nozzle 8 also comprises a distribution tubing 82 sealingly engaged inside the endpiece 74. The tubing 82 extends inside the casing 81 and both opens out at a dispensing orifice 83. Thus, the tubing 82 defines a portion of the radial duct section 73 with the dispensing orifice. 83 which defines the outlet end of this section 73. At its opposite end, the axial section 61 forms the inlet of the conduit. The fluid product discharged through the actuator rod 43 can thus flow through the section 71, the section 73 and the dispensing orifice 83 where it can be retrieved by the user. The distribution of the fluid product can be carried out in pulverized form or in the form of a dab of fluid product.

Sur les figures, l'obturateur 9 comprend un organe d'obturation 93 engagé dans la tubulure 82 de manière à pouvoir l'obturer au niveau de l'orifice de distribution 83. Ceci est le cas sur la figure 1. L'obturateur 9 comprend également une bague d'ancrage 99 en prise autour de l'ergot 69. L'organe d'obturation 93 est relié à la bague d'ancrage 99 au moyen d'un élément de liaison 92 qui présente ici une certaine résilience élastique. L'obturateur 9 est entièrement disposé à l'intérieur de la section de conduit radiale 73. Seule la paroi frontale d'extrémité de l'organe d'obturation 93 est tournée vers l'extérieur. La figure 1 représente le distributeur en position de repos, c'est-à-dire avec l'organe d'obturation 93 en prise étanche dans l'orifice de distribution 83. On peut remarquer que l'ergot 69 est situé à gauche de l'axe de symétrie XX. L'élément de liaison élastique 92 peut avantageusement aider à solliciter l'organe d'obturation 93 en contact étanche dans l'orifice de distribution 83. En faisant tourner le corps 7 en maintenant le récipient 1 fixement, l'orifice de distribution 83 effectue un déplacement en arc de cercle d'un rayon constant. Cependant, la bague d'ancrage 99 en prise autour de l'ergot 69 reste statique du fait que l'ergot 69 fait partie intégrante de l'insert 6 qui est fixe en rotation par rapport à l'organe de fixation 5, qui est lui-même fixe en rotation par rapport au récipient 1. Etant donné que l'ergot 69 s'étend de manière excentrée par rapport à l'axe XX, sa distance par rapport à l'orifice de distribution 83 varie lorsque l'on fait tourner le corps 7 par rapport à l'insert 6. Sur la figure 1, l'ergot 69 est positionné à gauche de l'axe XX, de sorte que la distance qui le sépare de l'orifice de distribution 83 est minimale. En revanche, après une rotation d'un quart de tour par exemple, l'ergot 69 peut être positionné au même niveau que l'axe XX sans pour autant être situé sur l'axe XX. Ceci est représenté sur la figure 3a. La distance qui sépare alors l'ergot 69 de l'orifice de distribution 83 a augmentée. Ceci a pour effet d'exercer une traction sur l'organe d'obturation 93 qui est relié à la bague d'ancrage 99 par l'intermédiaire de l'élément de liaison 92. En conséquence, l'organe d'obturation 93 se désengage de l'orifice de distribution 83 par déplacement à l'intérieur de la tubulure 82. Un passage est ainsi libéré autour de 1'organe d'obturation 93 pour le produit fluide refoulé hors de la tige d'actionnement à travers la section axiale 61 et la section radiale 73. La figure 3a correspond ainsi à la position d'ouverture de l'obturateur, qui correspond également à la position déverrouillée du système de verrouillage. De manière inversement symétrique, la figure 1 correspond à la position verrouillée du système de verrouillage et à la position d'obturation de l'obturateur. A partir de la position de la figure 3a, l'utilisateur peut appuyer sur la surface de poussoir 72 pour actionner la pompe 4. La jupe de verrouillage 75 peut s'engager dans le manchon de verrouillage 57, alors que la jupe de guidage 65 s'engage autour de la douille de guidage 56.In the figures, the shutter 9 comprises a shutter member 93 engaged in the pipe 82 so as to be able to close it at the dispensing orifice 83. This is the case on the figure 1 . The shutter 9 also comprises an anchor ring 99 engaged around the lug 69. The closure member 93 is connected to the anchor ring 99 by means of a connecting element 92 which here has a some elastic resilience. The shutter 9 is entirely disposed inside the radial duct section 73. Only the end end wall of the closure member 93 is turned outwards. The figure 1 represents the distributor in the rest position, that is to say with the closure member 93 in sealed engagement in the dispensing orifice 83. It may be noted that the lug 69 is situated to the left of the axis of symmetry XX. The elastic connecting element 92 can advantageously help to urge the closure member 93 into sealing contact in the dispensing orifice 83. By rotating the body 7 while holding the container 1 fixed, the dispensing orifice 83 moves in an arc of a constant radius. However, the anchor ring 99 engaged around the lug 69 remains static because the lug 69 is an integral part of the insert 6 which is fixed in rotation with respect to the fastener 5, which is it itself rotates relative to the container 1. Since the lug 69 extends eccentrically with respect to the axis XX, its distance relative to the dispensing orifice 83 varies when one makes turn the body 7 relative to the insert 6. On the figure 1 , the lug 69 is positioned to the left of the axis XX, so that the distance separating it from the dispensing orifice 83 is minimal. On the other hand, after a rotation of a quarter turn, for example, the lug 69 can be positioned at the same level as the axis XX without being located on the axis XX. This is represented on the figure 3a . The distance which then separates the lug 69 from the dispensing orifice 83 has increased. This has the effect of exerting traction on the closure member 93 which is connected to the anchor ring 99 via the connecting element 92. Consequently, the closure member 93 is disengages from the dispensing orifice 83 by moving inside the pipe 82. A passage is thus released around 1 'closure member 93 for the fluid discharged out of the actuating rod through the axial section 61 and the radial section 73. The figure 3a corresponds to the open position of the shutter, which also corresponds to the unlocked position of the locking system. Conversely, symmetrically, the figure 1 corresponds to the locked position of the locking system and the shutter position of the shutter. From the position of the figure 3a , the user can press the pusher surface 72 to actuate the pump 4. The locking skirt 75 can engage in the locking sleeve 57, while the guide skirt 65 engages around the guide sleeve 56.

Le corps 7, la buse 8, et dans une certaine mesure l'obturateur 9, constituent ensemble une partie rotative par rapport à l'insert 6 qui constitue une partie fixe en rotation.The body 7, the nozzle 8, and to some extent the shutter 9, together constitute a rotatable portion relative to the insert 6 which constitutes a fixed portion in rotation.

Il est tout à fait possible de mettre en oeuvre le système d'obturation par rotation du corps 7 indépendamment du système de verrouillage. Toutefois, l'association des deux systèmes est préférable, étant donné que l'actionnement de l'un est directement lié à l'actionnement de l'autre. Pour l'utilisateur, le système d'obturation de l'invention est parfaitement invisible ou transparent.It is quite possible to implement the system for closing the rotation of the body 7 independently of the locking system. However, the combination of the two systems is preferable, since the actuation of one is directly related to the actuation of the other. For the user, the sealing system of the invention is perfectly invisible or transparent.

Sur la figure 6, on voit une tête de distribution selon l'invention qui constitue une variante très proche de la tête de distribution de la figure 1. Seule la forme du corps 7 et de la buse 8 est différente. La vue éclatée permet de comprendre la séquence de montage des différents éléments constitutifs de la tête. Tout d'abord, l'obturateur 9 est engagé à l'intérieur de la section de conduit radiale 73 du corps 7 à travers l'embout 74. L'obturateur 9 est introduit jusqu'à ce que la bague d'ancrage 99 soit positionnée au niveau de la tubulure 76. Ensuite, l'insert 6 peut être rapporté à l'intérieur du corps 7 en faisant pénétrer l'ergot de déplacement 69 à travers la tubulure 76 de manière à l'introduire dans la bague d'ancrage 99. A ce moment, le clapet 9 est bloqué dans la section 73. Il suffit alors de rapporter la buse 8 sur l'embout 74. La tête est alors dans son état final de montage.On the figure 6 , we see a dispensing head according to the invention which is a very close variant of the dispensing head of the figure 1 . Only the shape of the body 7 and the nozzle 8 is different. The exploded view makes it possible to understand the assembly sequence of the different elements constituting the head. First, the shutter 9 is engaged inside the radial duct section 73 of the body 7 through the nozzle 74. The shutter 9 is introduced until the anchor ring 99 is positioned at the tubing 76. Then, the insert 6 can be attached inside the body 7 by causing the displacement pin 69 to penetrate through the tubing 76 so as to introduce it into the anchor ring. 99. At this time, the valve 9 is blocked in section 73. It is then sufficient to report the nozzle 8 on the nozzle 74. The head is then in its final state of assembly.

On se référera maintenant aux figures 7 et 8 pour expliquer un second mode de réalisation qui diffère du mode de réalisation précédent principalement en ce qui concerne l'obturateur et ses moyens de déplacement. Le reste de la tête de distribution et même du distributeur peut être totalement identique à celui du premier mode de réalisation de la figure 1. L'obturateur 9' de ce mode de réalisation comprend un organe d'obturation 93 qui peut être identique à celui du mode de réalisation précédent. L'obturateur 9' comprend un élément d'ancrage qui peut se présenter sous la forme d'un talon d'ancrage 99' en prise dans un logement 79 formé par le corps 7. L'obturateur 9' comprend également un élément de liaison formé par une tige 92' et deux lamelles 93 qui relient la tige 92' au talon d'ancrage 99' en définissant entre elles une fenêtre 930. Ceci est visible sur la figure 4. D'autre part, l'insert 6 forme un ergot de déplacement 69' sous la forme d'une lame 69' insérée dans la fenêtre 930 des lames 93. La lame 69' présente une dimension étroite et une dimension allongée. Dans la position d'obturation représentée sur la figure 4, la lame 69' est disposée dans la fenêtre 930 avec sa dimension allongée qui s'étend dans l'axe longitudinal de l'obturateur 9'. En d'autres termes, la lame 69' laisse les lames 93 sans contrainte. La lame 69' peut être disposée de manière parfaitement axiale sur l'axe XX. Après une rotation d'un quart de tour par exemple, on arrive dans la position d'ouverture déverrouillée de la figure 5. L'obturateur 9' a été tourné d'un quart de tour en laissant la lame 69' statique. Ceci a pour effet de déplacer la lame à l'intérieur de la fenêtre 930 de sorte que sa dimension allongée s'étend alors perpendiculairement à la direction longitudinale de l'obturateur 9'. La lame 69' contraint alors les lames 93 en éloignement l'une de l'autre en augmentant la dimension de la fenêtre 930. Ceci a pour effet de rapprocher l'organe d'obturation 93 du talon d'ancrage 99'. Etant donné que le talon est reçu fixement dans le logement 79, l'organe d'obturation 93 est contraint de se déplacer en retrait à l'intérieur de la section de conduit 73 de manière à dégager l'orifice de distribution 83. Le produit fluide issu de la tige d'actionnement 43 peut alors s'écouler à travers le conduit 73 et l'orifice de distribution 83.We will now refer to Figures 7 and 8 to explain a second embodiment which differs from the previous embodiment mainly with respect to the shutter and its moving means. The rest of the dispensing head and even the dispenser may be completely identical to that of the first embodiment of the figure 1 . The shutter 9 'of this embodiment comprises a shutter member 93 which may be identical to that of the previous embodiment. The shutter 9 'comprises an anchoring element which may be in the form of an anchor heel 99' engaged in a housing 79 formed by the body 7. The shutter 9 'also comprises a connecting element formed by a rod 92 'and two strips 93 which connect the rod 92' to the anchoring heel 99 'defining between them a window 930. This is visible on the figure 4 . On the other hand, the insert 6 forms a displacement pin 69 'in the form of a blade 69' inserted in the window 930 of the blades 93. The blade 69 'has a narrow dimension and an elongated dimension. In the closed position shown on the figure 4 , the blade 69 'is disposed in the window 930 with its elongate dimension extending in the longitudinal axis of the shutter 9 '. In other words, the blade 69 'leaves the blades 93 without stress. The blade 69 'can be arranged perfectly axially on the axis XX. After a rotation of a quarter of a turn, for example, we arrive in the unlocked opening position of the figure 5 . The shutter 9 'has been rotated a quarter turn leaving the blade 69' static. This has the effect of moving the blade inside the window 930 so that its elongated dimension then extends perpendicularly to the longitudinal direction of the shutter 9 '. The blade 69 'then forces the blades 93 away from each other by increasing the size of the window 930. This has the effect of bringing the closure member 93 of the anchoring heel 99'. Since the heel is fixedly received in the housing 79, the closure member 93 is constrained to move recessed within the conduit section 73 to disengage the dispensing orifice 83. The product fluid from the actuating rod 43 can then flow through the conduit 73 and the dispensing orifice 83.

Dans les deux modes de réalisation décrits précédemment, l'actionnement de l'obturateur s'effectue par un déplacement rotatif du corps 7 qui constitue une partie rotative de la tête de distribution. D'autre part, la tête comprend un insert 6 qui est monté fixement en rotation mais librement en translation axiale sur l'organe de distribution 4. Il faut également noter que l'organe d'obturation 93 effectue un mouvement de rotation avec la partie rotative de la tête de distribution.In the two embodiments described above, the actuation of the shutter is effected by a rotational movement of the body 7 which constitutes a rotating part of the dispensing head. On the other hand, the head comprises an insert 6 which is fixedly mounted in rotation but freely in axial translation on the dispensing member 4. It should also be noted that the shutter member 93 rotates with the part rotary of the dispensing head.
