Description

La présente invention concerne une tête de distribution d'un produit destinée à l'actionnement d'un organe de distribution monté sur un récipient, notamment d'une valve montée sur un récipient pressurisé, et à la distribution d'un produit contenu dans le récipient. En particulier, l'invention concerne une tête de distribution pouvant se déplacer entre une position de distribution et une position de stockage.The present invention relates to a dispensing head of a product intended for the actuation of a dispensing member mounted on a container, in particular of a valve mounted on a pressurized container, and to the dispensing of a product contained in the container. In particular, the invention relates to a dispensing head that can move between a dispensing position and a storage position.

Généralement, les têtes de distribution sont protégées par des capots afin d'éviter toute distribution involontaire de produit. Toutefois, les capots peuvent facilement s'enlever de façon accidentelle ce qui n'est pas souhaitable, en particulier lorsque la tête de distribution est prévue sur un distributeur de type aérosol et que les risques de fuite du produit, notamment du gaz propulseur de l'aérosol, doivent absolument être évités.Generally, the dispensing heads are protected by covers to avoid any unintentional dispensing of product. However, the covers can easily be accidentally removed, which is undesirable, particularly when the dispensing head is provided on an aerosol-type dispenser and the risk of leakage of the product, especially the propellant of the aerosol dispenser. aerosol, must absolutely be avoided.

Pour éviter la distribution involontaire de produit, il est connu de réaliser des têtes de distribution pouvant passer d'une position de distribution à une position de stockage dans laquelle le produit ne peut être distribué. Le document US 2,887,273 décrit un exemple de tête de distribution de ce type qui comporte un diffuseur fixé sur un récipient et sur une tige de valve associée au récipient, ainsi qu'un bouton-poussoir prévu pour actionner la tige de valve. Pour passer d'une position de distribution à une position de stockage, le bouton-poussoir est mobile en rotation par rapport au diffuseur. Le diffuseur comporte un tube creux fixé sur la tige de valve, le tube comprenant deux orifices de pulvérisation latéraux diamétralement opposés. Le bouton-poussoir comporte une jupe emmanchée sur le tube, la jupe délimitant une ouverture destinée à être mise en regard de l'un ou l'autre des orifices de pulvérisation dans la position de distribution. En position de stockage, l'ouverture formée dans la jupe du bouton-poussoir est positionnée en regard de la paroi du tube située entre les deux orifices. Aucun produit ne peut ainsi être distribué. Toutefois, dans cette position, rien n'empêche l'enfoncement du bouton-poussoir de sorte que du produit peut s'accumuler à l'intérieur du tube et des orifices de pulvérisation du diffuseur. Le produit risque donc au cours du temps de sécher et de boucher les orifices. Le document EP 1 024 094 décrit également une tête de distribution selon le préambule de la revendication 1.To avoid the unintentional dispensing of product, it is known to make dispensing heads that can pass from a dispensing position to a storage position in which the product can not be dispensed. The document US 2,887,273 discloses an example of a dispensing head of this type which has a diffuser attached to a container and a valve stem associated with the container, and a push button for actuating the valve stem. To move from a distribution position to a storage position, the push button is rotatable relative to the diffuser. The diffuser comprises a hollow tube fixed on the valve stem, the tube comprising two diametrically opposite lateral spray orifices. The push button has a skirt fitted on the tube, the skirt defining an opening intended to be placed opposite one or the other of the spray orifices in the dispensing position. In the storage position, the opening formed in the skirt of the push button is positioned opposite the wall of the tube located between the two orifices. No product can be distributed. However, in this position, nothing prevents the depression of the push button so that product can accumulate inside the tube and spray holes of the diffuser. The product thus risks over time to dry and plug the orifices. The document EP 1 024 094 also discloses a dispensing head according to the preamble of claim 1.

Aussi, est-ce un des objets de l'invention que de réaliser une tête de distribution qui ne présente pas les inconvénients de la technique antérieure.Also, is it an object of the invention to provide a dispensing head which does not have the disadvantages of the prior art.

C'est encore un objet de l'invention que de réaliser une nouvelle tête de distribution qui évite la distribution accidentelle de produit.It is another object of the invention to provide a new dispensing head which avoids the accidental dispensing of product.

C'est en particulier un objet de l'invention que de réaliser une telle tête qui soit simple à réaliser et peu onéreuse.It is particularly an object of the invention to provide such a head which is simple to produce and inexpensive.

Selon l'invention, ces objets peuvent être atteints en réalisant une tête de distribution selon la revendication 1 destinée à l'actionnement d'un organe de distribution monté sur un récipient et à la distribution d'un produit contenu dans le récipient.According to the invention, these objects can be achieved by producing a dispensing head according to claim 1 for actuating a dispensing member mounted on a container and dispensing a product contained in the container.

Une telle tête de distribution peut être mise dans une position de sécurité dans laquelle le produit ne peut être distribué, cette position pouvant difficilement être changée de façon accidentelle contrairement à des têtes protégées uniquement par des capots qui peuvent facilement s'enlever de façon accidentelle. On évite également les risques de pollution bactériologique à l'extérieur de la tête étant donné qu'en position de stockage la tête n'est pas recouverte de capot et reste donc à l'air.Such a dispensing head can be put in a safety position in which the product can not be dispensed, this position can hardly be changed accidentally unlike heads protected only by covers that can easily be removed accidentally. We avoid also the risk of bacteriological pollution outside the head since in the storage position the head is not covered with a hood and therefore remains in the air.

En outre, l'organe de distribution ne pouvant être actionné lorsque l'ouverture du conduit est obturée, le produit ne peut sortir du récipient dans cette position et s'accumuler dans le conduit. On évite ainsi les risques de bouchage du conduit.In addition, the dispensing member can not be actuated when the opening of the duct is closed, the product can not leave the container in this position and accumulate in the conduit. This avoids the risk of clogging the duct.

De plus, la présence des moyens de liaison élastiquement déformables permet de réaliser un conduit par un procédé de moulage à partir d'une seule pièce avec des moyens de fixation, qui peut se déplacer par rapport aux moyens de fixation. Une telle pièce est simple à réaliser et est peu onéreuse.In addition, the presence of the elastically deformable connecting means makes it possible to produce a duct by a molding process from a single piece with fixing means, which can move relative to the fixing means. Such a piece is simple to make and is inexpensive.

Avantageusement, la tête de distribution peut être configurée de manière à n'autoriser l'actionnement de l'organe de distribution que lorsque les moyens d'actionnement sont dans la première position. L'organe de distribution ne peut ainsi pas être actionné dans une position intermédiaire située entre la première et la seconde position afin d'éviter que du produit puisse arriver dans le conduit alors que l'ouverture du conduit est obturée.Advantageously, the dispensing head may be configured to allow actuation of the dispensing member only when the actuating means are in the first position. The dispenser member can not be actuated in an intermediate position between the first and second position to prevent product can arrive in the conduit while the opening of the conduit is closed.

La tête de distribution peut comprendre une butée axiale contre laquelle les moyens d'actionnement sont aptes à venir en appui axialement au moins lorsqu'ils ne sont pas dans la première position de manière à empêcher l'actionnement de l'organe de distribution. La butée axiale peut en outre être configurée de manière que les moyens d'actionnement sont aptes à venir en butée axialement contre elle entre la première et la seconde position, à savoir dans toutes les positions autres que la première position.The dispensing head may comprise an axial abutment against which the actuating means are able to bear axially at least when they are not in the first position so as to prevent actuation of the dispenser member. The axial stop may also be configured so that the actuating means are able to abut axially against it between the first and the second position, namely in all positions other than the first position.

L'orifice de distribution peut être formé à l'extrémité d'un canal et le conduit débouche sur au moins une ouverture apte à être mise en regard du canal dans la première position et apte à être obturée dans la seconde position. L'ouverture du conduit étant obturée lorsque la tête n'est pas en position de distribution, le conduit est fermé de manière étanche en position de stockage.The dispensing orifice may be formed at the end of a channel and the conduit opens on at least one aperture adapted to be placed facing the channel in the first position and able to be closed in the second position. The opening of the duct being closed when the head is not in the dispensing position, the duct is sealed in the storage position.

Le conduit peut déboucher sur une ouverture unique apte à être mise en regard du canal.The duct can lead to a single opening that can be placed next to the channel.

L'ouverture peut être une fente s'étendant parallèlement à un axe longitudinal X de la tête. Il est bien évident que toute autre forme d'ouverture peut être utilisée.The opening may be a slot extending parallel to a longitudinal axis X of the head. It is obvious that any other form of opening can be used.

Le canal à l'extrémité duquel est formé l'orifice de distribution peut avoir une longueur supérieure au diamètre de l'orifice de distribution. Par diamètre de l'orifice de distribution, on entend le diamètre du cercle lorsque l'orifice est circulaire, ou le diamètre du cercle circonscrit à la section de l'orifice lorsque celui-ci a une forme différente d'un cercle.The channel at the end of which is formed the dispensing orifice may have a length greater than the diameter of the dispensing orifice. By diameter of the dispensing orifice is meant the diameter of the circle when the orifice is circular, or the diameter of the circle circumscribing the section of the orifice when it has a shape different from a circle.

Avantageusement, les moyens de fixation sont montés de manière fixe axialement sur le récipient de manière à ce que la tête soit correctement maintenue sur le récipient.Advantageously, the fixing means are fixedly mounted axially on the container so that the head is properly held on the container.

Avantageusement, les moyens de liaisons sont élastiquement déformables, de sorte qu'ils reprennent leur position initiale lorsque la contrainte qui les déforme cesse.Advantageously, the connecting means are elastically deformable, so that they resume their initial position when the constraint that deforms them ceases.

Les moyens de liaison autorisent un déplacement du conduit en réponse à l'actionnement des moyens d'actionnement.The connecting means allow a displacement of the conduit in response to the actuation of the actuating means.

Selon un mode de réalisation préféré, les moyens de liaison sont constitués par une paroi transversale à un axe longitudinal X de la tête, qui peut être ondulée. Cette configuration de la paroi lui permet de facilement se déformer et de revenir facilement dans sa position initiale.According to a preferred embodiment, the connecting means are constituted by a wall transverse to a longitudinal axis X of the head, which may be corrugated. This configuration of the wall allows it to easily deform and return easily to its initial position.

Le conduit est formé selon un axe longitudinal X de la tête et comporte une première extrémité apte à coopérer avec l'organe de distribution et une seconde extrémité sur laquelle sont emmanchés les moyens d'actionnement. Ainsi, le conduit transmet directement la pression exercée sur les moyens d'actionnement à l'organe de distribution.The duct is formed along a longitudinal axis X of the head and has a first end adapted to cooperate with the dispensing member and a second end on which are fitted the actuating means. So, the conduit directly transmits the pressure exerted on the actuating means to the dispensing member.

Une pointe peut être disposée à l'intérieur du conduit de manière à définir un passage annulaire pour le produit sur une partie au moins du conduit.A tip may be disposed within the conduit to define an annular passage for the product on at least a portion of the conduit.

Les moyens d'actionnement peuvent être mobiles en rotation autour de l'axe X entre les première et seconde positions.The actuating means may be rotatable about the X axis between the first and second positions.

Avantageusement, la tête de distribution peut comprendre au moins deux butées radiales limitant le mouvement de rotation des moyens d'actionnement.Advantageously, the dispensing head may comprise at least two radial stops limiting the rotational movement of the actuating means.

Avantageusement encore, la tête de distribution peut comprendre des moyens d'identification sonore pour signaler la mise en position dans l'une ou l'autre des première et seconde positions. Les moyens d'identification sonore peuvent être constitués par la coopération d'un premier relief formé sur les moyens d'actionnement et d'un second relief, le premier relief étant apte, lors du déplacement des moyens d'actionnement par rapport au conduit, à venir au contact du second relief et à le franchir en le déformant élastiquement de manière à produire un signal sonore. L'utilisateur peut ainsi s'assurer que la tête est bien mise dans l'une ou l'autre des positions, et en particulier en position de stockage.Advantageously, the dispensing head may comprise sound identification means for signaling the positioning in one or the other of the first and second positions. The sound identification means may be constituted by the cooperation of a first relief formed on the actuating means and a second relief, the first relief being suitable, during the displacement of the actuating means with respect to the duct, to come into contact with the second relief and to cross it by deforming it elastically so as to produce a sound signal. The user can thus ensure that the head is put in one or the other of the positions, and in particular in the storage position.

La tête de distribution peut également comprendre des moyens d'identification visuelle pour identifier les première et seconde positions.The dispensing head may also include visual identification means for identifying the first and second positions.

L'orifice de distribution peut être défini par une buse rapportée ou une grille rapportée pour distribuer un produit sous forme de mousse.The dispensing orifice may be defined by an attached nozzle or an attached grid for dispensing a foam product.

L'invention concerne également un ensemble de conditionnement et de distribution d'un produit comprenant :

  • un récipient contenant le produit et équipé d'un organe de distribution ;
  • une tête de distribution telle qu'elle vient d'être décrite prévue pour activer l'organe de distribution afin de distribuer le produit.
The invention also relates to a package for packaging and dispensing a product comprising:
  • a container containing the product and equipped with a dispensing member;
  • a dispensing head as just described intended to activate the dispensing member to distribute the product.

Le récipient peut être pressurisé et l'organe de distribution peut être une valve mâle comprenant une tige de valve sur laquelle le conduit est emmanché, ou bien une valve femelle, c'est-à-dire sans tige de valve, dans laquelle est emmanché le conduit. Alternativement, le récipient est à pression atmosphérique et est équipé d'une pompe.The container may be pressurized and the dispensing member may be a male valve comprising a valve stem on which the conduit is fitted, or a female valve, that is to say without valve stem, in which is fitted the conduit. Alternatively, the container is at atmospheric pressure and is equipped with a pump.

L'invention est particulièrement utile pour le conditionnement et la distribution d'un produit cosmétique ou de soin, notamment d'un produit déodorant.The invention is particularly useful for the packaging and dispensing of a cosmetic or care product, especially a deodorant product.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un ensemble de conditionnement et de distribution d'un produit selon la revendication 22.The invention further relates, independently or in combination with the foregoing, to a package for packaging and dispensing a product according to claim 22.

Au sens de la présente invention, on entend par "produit déodorant" tout produit contenant une composition capable de réduire le flux sudoral, masquer, absorber, améliorer et/ou réduire l'odeur désagréable résultant de la décomposition de la sueur humaine par les bactéries.For the purposes of the present invention, the term "deodorant product" any product containing a composition capable of reducing the flow of sweat, mask, absorb, improve and / or reduce the unpleasant odor resulting from the decomposition of human sweat by bacteria .

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 illustre une vue en perspective d'un mode de réalisation d'un ensemble de conditionnement et de distribution muni d'une tête de distribution selon l'invention ;

The invention consists, apart from the arrangements set out above, in a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • the figure 1 illustrates a perspective view of an embodiment of a packaging and dispensing assembly provided with a dispensing head according to the invention;
  • the figure 2 illustrates an exploded view of the embodiment of the figure 1 ;

  • the figure 6 represents a detail of the dispensing head during the transition from the closed position to the dispensing position; and
  • the figure 7 represents in axial section the dispensing head in the dispensing position, the valve being actuated.

L'ensemble de conditionnement et de distribution illustré sur les figures 1 à 7 est formé d'un récipient pressurisé 30 sur lequel est fixée une tête de distribution 1 selon l'invention.The packaging and distribution package illustrated on the Figures 1 to 7 is formed of a pressurized container 30 on which is fixed a dispensing head 1 according to the invention.

Le récipient 30 est formé par un bidon pressurisé d'axe X, formé par un corps cylindrique 31 de révolution, dont l'extrémité supérieure est fermée par une coupelle 32 sertie sur un bord roulé 33 du récipient. La coupelle 32 est munie d'une valve 34 qui comporte une tige de valve 35 creuse et qui peut être actionnée par exemple par enfoncement de la tige de valve. Il est bien évident que l'on peut alternativement utiliser une valve qui peut être actionnée par basculement de la tige de valve.The container 30 is formed by a pressurized canister X axis, formed by a cylindrical body 31 of revolution, the upper end is closed by a cup 32 set on a rolled edge 33 of the container. The cup 32 is provided with a valve 34 which has a hollow valve stem 35 and which can be actuated for example by depressing the valve stem. It is obvious that one can alternatively use a valve that can be actuated by tilting of the valve stem.

Le récipient 30 peut contenir un produit à pulvériser, par exemple un produit cosmétique, et un gaz propulseur, lequel peut être ou non stocké sous une forme liquéfiée dans le récipient 30 et être ou non délivré avec le produit. Le produit sort alors sous forme de spray, c'est-à-dire sous la forme de fines particules en suspension soit dans le gaz, soit dans l'air.The container 30 may contain a product to be sprayed, for example a cosmetic product, and a propellant, which may or may not be stored in liquefied form in the container 30 and may or may not be delivered with the product. The product then exits in the form of a spray, that is to say in the form of fine particles in suspension either in the gas or in the air.

La tête de distribution 1 est également d'axe X et est formée de deux parties mobiles l'une par rapport à l'autre entre deux positions, une première position permettant la distribution du produit et une seconde position de stockage dans laquelle le produit ne peut être distribué. La première partie de la tête est constituée d'une frette 10 permettant de protéger la tige de valve et destinée à être fixée sur le récipient. La seconde partie est constituée d'un bouton-poussoir 20, permettant l'actionnement de la valve et qui est mobile en rotation par rapport à la frette. Chacune des deux pièces est obtenue de moulage d'un matériau thermoplastique à partir d'une seule pièce.The dispensing head 1 is also X-axis and is formed of two parts movable relative to each other between two positions, a first position for dispensing the product and a second storage position in which the product does not can be distributed. The first part of the head consists of a hoop 10 for protecting the valve stem and intended to be fixed on the container. The second part consists of a push button 20, allowing the actuation of the valve and which is rotatable relative to the hoop. Each of the two pieces is obtained by molding a thermoplastic material from a single piece.

La frette 10 comprend une jupe de fixation 11 pour fixer la tête sur le récipient. La jupe de fixation 11 est munie d'un bourrelet annulaire 110 sur sa paroi intérieure permettant de la fixer sur le récipient par encliquetage sous le bord roulé 33 du récipient et la coupelle 32. La jupe de fixation 11 présente un décrochement radial 111 vers l'intérieur de la jupe et se prolonge axialement au-dessus du décrochement jusqu'à une extrémité supérieure depuis laquelle est formée une paroi transversale 12. Des ailettes radiales 13, angulairement espacées sur la périphérie de la surface interne de la jupe de fixation, s'étendent parallèlement à l'axe X depuis le décrochement 111 jusqu'à un bord libre inférieur 130. Le bord libre 130 est prévu pour venir en butée contre le récipient en position montée de la frette sur le récipient, comme on le voit sur les figures 4, 5 et 7. Les ailettes 13 permettent ainsi de limiter l'enfoncement axial de la frette lors de son encliquetage sur le récipient.The hoop 10 comprises a fastening skirt 11 for fixing the head on the container. The fixing skirt 11 is provided with an annular bead 110 on its inner wall making it possible to fix it on the container by snapping under the rolled edge 33 of the container and the cup 32. The fixing skirt 11 has a radial recess 111 towards the inside the skirt and extends axially above the recess to an upper end from which is formed a transverse wall 12. Radial fins 13, angularly spaced on the periphery of the inner surface of the fixing skirt, s extend parallel to the X axis from the recess 111 to a lower free edge 130. The free edge 130 is provided to abut against the container in the mounted position of the hoop on the container, as seen on the Figures 4, 5 and 7 . The fins 13 thus make it possible to limit the axial depression of the hoop when it snaps onto the container.

La paroi transversale 12 est une paroi fine qui présente une ondulation de sorte qu'elle est élastiquement déformable ce qui lui permet de se déformer lorsqu'on la sollicite axialement. La paroi 12 est traversée en son centre par un conduit 14 formé dans l'axe X.The transverse wall 12 is a thin wall which has a corrugation so that it is elastically deformable which allows it to deform when the axially solicits. The wall 12 is traversed at its center by a conduit 14 formed in the X axis.

Le conduit 14 s'étend de part et d'autre de la paroi transversale 12 depuis une extrémité inférieure 14a ouverte qui vient s'emmancher sur la tige de valve 35, jusqu'à une extrémité supérieure 14b, également ouverte, sur laquelle vient s'emmancher une jupe axiale 23 du bouton-poussoir. Une gorge annulaire 14c est prévue sur la surface externe du conduit 14 pour recevoir un cordon annulaire 23a prévu sur la surface interne de la jupe axiale 23 du bouton-poussoir afin d'assurer le maintien axial du bouton-poussoir sur la frette. En outre, la coopération du cordon annulaire 23a avec la gorge annulaire 14c assure une étanchéité entre le conduit et l'intérieur du bouton-poussoir.The conduit 14 extends on either side of the transverse wall 12 from an open lower end 14a which is engaged on the valve stem 35, to an upper end 14b, also open, on which comes s to press an axial skirt 23 of the push-button. An annular groove 14c is provided on the outer surface of the conduit 14 to receive an annular bead 23a provided on the inner surface of the axial skirt 23 of the push button to ensure the axial retention of the push button on the hoop. In addition, the cooperation of the annular bead 23a with the annular groove 14c ensures a seal between the conduit and the inside of the push button.

Le conduit 14 est de forme cylindrique de révolution et définit dans sa partie inférieure un logement épaulé dans lequel peut s'engager de manière sensiblement étanche la partie supérieure de la tige de valve 35 dont l'extrémité supérieure 35a vient en butée contre l'épaulement du logement. L'extrémité inférieure 14a du conduit s'évase légèrement afin de faciliter la mise en place du conduit sur la tige de valve. L'extrémité supérieure 14b comporte une fente axiale 15a qui définit un passage permettant de faire sortir le produit.The duct 14 has a cylindrical shape of revolution and defines in its lower part a shouldered housing in which the upper part of the valve stem 35, whose upper end 35a abuts against the shoulder, can be substantially sealingly engaged. housing. The lower end 14a of the channel flares slightly to facilitate the introduction of the conduit on the valve stem. The upper end 14b has an axial slot 15a which defines a passage for moving the product.

La jupe de fixation 11 se raccorde au niveau du décrochement 111, par une paroi transversale annulaire 16, à une jupe extérieure 17, concentrique de la jupe de fixation 11. La jupe extérieure 17 est destinée à former le prolongement de la paroi du récipient lorsque la tête de distribution est montée sur le récipient. Deux marques M sont prévues sur la surface externe de cette jupe 17 qui indiquent visuellement les positions angulaires de la fente 15a et de la position d'obturation. Une première marque M est par exemple le mot "ON" qui correspond à la position de la fente 15a et donc qui permet une distribution du produit, et une seconde marque M est par exemple le mot "OFF" qui correspond à la position de stockage.The fastening skirt 11 is connected at the recess 111, by an annular transverse wall 16, to an outer skirt 17, concentric with the fastening skirt 11. The outer skirt 17 is intended to form the extension of the wall of the container when the dispensing head is mounted on the container. Two marks M are provided on the outer surface of this skirt 17 which visually indicate the angular positions of the slot 15a and the closed position. A first mark M is for example the word "ON" which corresponds to the position of the slot 15a and thus which allows a distribution of the product, and a second mark M is for example the word "OFF" which corresponds to the storage position .

Comme on le voit plus en détail à la figure 3, la paroi transversale annulaire 16 de la frette est traversée par deux ouvertures en arc de cercle 18 et 19, diamétralement opposées sur la paroi transversale annulaire, formées à proximité de la jupe extérieure 17, et dans lesquelles sont destinées à se déplacer deux pattes du bouton-poussoir, comme on le verra en détail par la suite. La première ouverture 18 est formée du côté de la fente axiale 15a du conduit et la seconde ouverture 19 est formée à l'arrière de la fente axiale 15a.As can be seen in more detail at figure 3 the annular transverse wall 16 of the ferrule is traversed by two arcuate openings 18 and 19, diametrically opposed on the annular transverse wall formed near the outer skirt 17, and in which are intended to move two legs of the push button, as will be seen in detail later. The first opening 18 is formed on the side of the axial slot 15a of the conduit and the second opening 19 is formed at the rear of the axial slot 15a.

La seconde ouverture en arc de cercle 19 se termine, à proximité de l'une de ses extrémités, par une portion d'ouverture 19a qui prolonge radialement vers l'intérieur l'ouverture 19. La portion d'ouverture 19a est formée selon le diamètre passant par la fente axiale 15a. La portion 160 de la paroi transversale annulaire 16 située à proximité de la seconde ouverture 19, à l'intérieur de l'arc de cercle, sert de butée axiale pour le bouton-poussoir comme on le verra en détail ultérieurement.The second opening in an arc of circle 19 ends, near one of its ends, by an opening portion 19a which extends radially inwardly the opening 19. The opening portion 19a is formed according to the diameter passing through the axial slot 15a. The portion 160 of the annular transverse wall 16 located near the second opening 19, within the arc, serves as an axial stop for the push button as will be seen in detail later.

Deux butées verticales 190a et 190b bordent respectivement chaque extrémité de la seconde ouverture en arc de cercle 19. Les butées 190a et 190b s'étendent axialement depuis la paroi transversale annulaire 16 jusqu'à un bord libre supérieur, et s'étendent radialement depuis la surface externe de la jupe de fixation 11 jusqu'à la fente 19. Les butées 190a et 190b sont relativement rigides du fait qu'elles sont solidaires à la fois de la paroi annulaire transversale 16 et de la jupe de fixation 11, et permettent ainsi de limiter le mouvement de rotation du bouton-poussoir.Two vertical stops 190a and 190b respectively border each end of the second arcuate opening 19. The stops 190a and 190b extend axially from the annular transverse wall 16 to an upper free edge, and extend radially from the outer surface of the fastening skirt 11 to the slot 19. The stops 190a and 190b are relatively rigid because they are secured to both the transverse annular wall 16 and the fastening skirt 11, and thus allow to limit the rotational movement of the pushbutton.

Deux languettes radiales 191a et 191b s'étendent axialement depuis la paroi transversale annulaire 16 jusqu'à un bord libre supérieur 191a' et 191b'. L'une est formée du côté du bord intérieur de la portion d'ouverture 19a et l'autre est formée à une distance de la butée 190b. Les languettes 191a et 191b s'étendent, sur une hauteur axiale inférieure à celle des butées 190a et 190b et sont également moins larges que les butées 190a et 190b. Les languettes 191 a et 191b ne s'étendent pas jusqu'à l'ouverture en arc de cercle 19 et sont formées à distance de la jupe de fixation 11 de sorte qu'elles sont élastiquement déformables. Les languettes 191a et 191b coopèrent avec le bouton-poussoir de manière à constituer un moyen d'identification sonore pour indiquer le passage en position d'utilisation et en position de stockage.Two radial tabs 191a and 191b extend axially from the annular transverse wall 16 to an upper free edge 191a 'and 191b'. One is formed on the inner edge side of the opening portion 19a and the other is formed at a distance from the stopper 190b. The tabs 191a and 191b extend over an axial height less than that of the stops 190a and 190b and are also narrower than the stops 190a and 190b. The tongues 191a and 191b do not extend to the opening in an arc 19 and are formed at a distance from the fixing skirt 11 so that they are elastically deformable. The tabs 191a and 191b cooperate with the push button so as to constitute a sound identification means to indicate the passage in the use position and in the storage position.

De préférence, la position de distribution est assez éloignée angulairement de la position de stockage de manière à parfaitement séparer ces deux positions. On évite ainsi que l'utilisateur fasse passer le bouton-poussoir dans la position de distribution sans le souhaiter. Les deux positions étant relativement éloignées, le bouton-poussoir peut alors prendre différentes positions intermédiaires dans lesquelles il n'est pas souhaitable que l'organe de distribution puisse être actionné. C'est pourquoi, il est préférable que la portion 160 serve de butée axiale pour le bouton-poussoir entre ces deux positions. Toutefois, on peut en variante prévoir que la portion 160 de la paroi transversale annulaire 16 située à proximité de la seconde ouverture 19, à l'intérieur de l'arc de cercle, peut ne servir de butée axiale pour le bouton-poussoir que dans la position de stockage. La portion 160 située entre les deux languettes radiales 191a et 191b s'étend alors radialement au même niveau que la portion 160 de la paroi située entre la languette 191a et la butée verticale 190a.Preferably, the dispensing position is rather angularly distant from the storage position so as to perfectly separate these two positions. This prevents the user push the push button into the dispensing position without wishing. The two positions being relatively far apart, the pushbutton can then take different intermediate positions in which it is not desirable that the dispensing member can be actuated. Therefore, it is preferable that the portion 160 serves as an axial stop for the push button between these two positions. However, it may alternatively be provided that the portion 160 of the annular transverse wall 16 located near the second opening 19, inside the arc, may serve as an axial stop for the pushbutton only in the storage position. The portion 160 located between the two radial tabs 191a and 191b then extends radially at the same level as the portion 160 of the wall located between the tongue 191a and the vertical stop 190a.

Pour actionner la valve, la tête de distribution comprend un bouton-poussoir 20 qui comporte une paroi supérieure 21, destinée à servir d'appui à un doigt de l'utilisateur. La paroi supérieure 21 se raccorde en périphérie à une première jupe 22, de diamètre inférieur au diamètre de la jupe extérieure 17 de la frette.To actuate the valve, the dispensing head comprises a push button 20 which has an upper wall 21, intended to serve as a support for a finger of the user. The upper wall 21 is connected at the periphery to a first skirt 22, of smaller diameter than the diameter of the outer skirt 17 of the hoop.

Le bouton-poussoir 20 comporte, à l'intérieur de la première jupe 22, une deuxième jupe 23, cylindrique de révolution. La jupe 23 est d'axe X et vient s'emmancher sur l'extrémité supérieure 14b du conduit 14 autour duquel elle est mobile en rotation. Dans la partie supérieure de la jupe 23 débouche, par une première extrémité 24a, un canal 24, sensiblement radial, dont la seconde extrémité 24b débouche dans un support de buse. Le support de buse comporte un plot 25, ou "centerpost" sur lequel peut être fixée une buse à canaux tourbillonnaires 50 conventionnelle. La buse 50 définit un orifice de distribution 51.The push-button 20 comprises, inside the first skirt 22, a second skirt 23, cylindrical of revolution. The skirt 23 is X-axis and comes to slip on the upper end 14b of the conduit 14 around which it is rotatable. In the upper part of the skirt 23 opens, through a first end 24a, a channel 24, substantially radial, the second end 24b opens into a nozzle holder. The nozzle support comprises a stud 25, or "centerpost" on which can be attached a conventional swirl channel nozzle 50. The nozzle 50 defines a dispensing orifice 51.

Une flèche F est prévue sur la paroi supérieure 21 pour indiquer la position angulaire de l'extrémité 24a du canal 24, de sorte que lorsqu'elle est mise en regard de l'une ou l'autre marque M prévue sur la frette, cela indique visuellement à l'utilisateur la position dans laquelle il peut actionner le bouton-poussoir pour distribuer le produit et la position de stockage.An arrow F is provided on the upper wall 21 to indicate the angular position of the end 24a of the channel 24, so that when it is set Regardless of the M mark provided on the hoop, this visually indicates to the user the position in which he can actuate the push button to distribute the product and the storage position.

Une pointe 26 d'axe X est formée à l'intérieur de la deuxième jupe 23 et vient s'insérer à l'intérieur du conduit 14 lorsque le bouton-poussoir est monté sur la frette. La pointe 26 a un diamètre légèrement inférieur à celui du conduit de manière à former un passage annulaire pour le produit à l'intérieur du conduit. La pointe 26 permet de limiter le volume mort à l'intérieur du conduit et ainsi limiter les pertes de charge à l'intérieur du conduit afin d'optimiser le débit avec lequel le produit sort. En outre, en diminuant le volume mort, on diminue le volume de produit que peut contenir la tête de distribution entre la valve 34 et l'orifice de distribution 51. Ainsi, la pulvérisation du produit par l'orifice de distribution s'arrête sensiblement à l'instant où l'utilisateur relâche le bouton-poussoir, c'est-à-dire dès que la valve n'est plus ouverte puisque la quantité de produit restant à l'intérieur de la tête est relativement faible.An X axis tip 26 is formed inside the second skirt 23 and is inserted inside the conduit 14 when the push button is mounted on the hoop. The tip 26 has a diameter slightly smaller than that of the conduit so as to form an annular passage for the product inside the conduit. The tip 26 makes it possible to limit the dead volume inside the duct and thus limit the pressure drops inside the duct in order to optimize the flow rate with which the product leaves. In addition, by decreasing the dead volume, it reduces the volume of product that can contain the dispensing head between the valve 34 and the dispensing orifice 51. Thus, the spraying of the product through the dispensing orifice stops substantially. at the moment when the user releases the push button, that is to say as soon as the valve is no longer open since the quantity of product remaining inside the head is relatively small.

La jupe périphérique 22 du bouton-poussoir se prolonge axialement, dans sa partie inférieure, sur deux portions angulaires diamétralement opposées, par deux pattes 27 et 28, prévues chacune pour se déplacer respectivement dans les ouvertures en arc de cercle 18 et 19 prévues dans la frette. Chaque patte 27 et 28 est munie à son extrémité inférieure d'un crochet 270 et 280 qui vient en butée sous la paroi transversale annulaire 16, lorsque les pattes traversent les ouvertures 27 et 28. Les crochets 270 et 280 servent à maintenir axialement le bouton-poussoir sur la frette. La patte 27, située du côté de l'orifice de distribution 51, est prévue pour se déplacer dans l'ouverture en arc de cercle 18. La patte 28 est prévue pour se déplacer dans l'ouverture en arc de cercle 19. La patte 28 comprend une nervure 281 dont la longueur axiale et la longueur radiale sont suffisantes pour venir en butée contre chaque butée 190a et 190b lors du mouvement de rotation du bouton-poussoir sur la frette. La nervure 281 présente un épaulement 281 a dans sa partie inférieure qui lui permet de passer à distance du bord vertical des languettes 191a et 191b. Toutefois, l'épaulement 281 a vient en contact avec les bords libres supérieurs 191a' et 191b' de chaque languette 191a et 191b et les franchit en les déformant élastiquement, comme on le voit à la figure 6, de manière à produire un signal sonore.The peripheral skirt 22 of the push-button extends axially, in its lower part, on two diametrically opposite angular portions, by two tabs 27 and 28, each provided for moving respectively in the arcuate openings 18 and 19 provided in FIG. fret. Each tab 27 and 28 is provided at its lower end with a hook 270 and 280 which abuts under the annular transverse wall 16, when the tabs pass through the openings 27 and 28. The hooks 270 and 280 serve to axially hold the button - push on the fret. The tab 27, located on the side of the dispensing orifice 51, is provided to move in the opening in a circular arc 18. The tab 28 is provided to move in the opening in an arc 19. The leg 28 comprises a rib 281 whose axial length and radial length are sufficient to abut against each stop 190a and 190b during the rotational movement of the push button on the hoop. The rib 281 has a shoulder 281a in its lower part which allows it to move away from the vertical edge of the tabs 191a and 191b. However, the shoulder 281a comes into contact with the upper free edges 191a 'and 191b' of each tongue 191a and 191b and passes through them. deforming elastically, as seen in the figure 6 , so as to produce a sound signal.

En position de stockage représentée sur la figure 4, le conduit 14 obture l'extrémité 24a du canal 24 de manière à empêcher toute communication entre l'orifice de sortie 51 et l'intérieur du conduit de distribution 14. Le conduit est ainsi fermé de façon étanche par la coopération de deux pièces cylindriques. Dans cette position, la nervure 281 est en butée contre la butée 190b. En outre, la patte 28 traverse la fente 19 et se situe à l'extrémité de l'ouverture 19 opposée à l'ouverture 19a. L'extrémité inférieure de la nervure 281 formée sur le bouton-poussoir est en butée axiale contre la portion 160 de la paroi transversale annulaire 16 de sorte que si l'utilisateur appuie sur le bouton-poussoir 20, en particulier sur la zone de la paroi supérieure 21 située à l'opposé de l'orifice de distribution 51, celui-ci ne peut s'enfoncer et ne peut donc pas actionner la valve 34. On empêche ainsi tout actionnement involontaire de la valve. On peut en outre prévoir sur la surface interne de la jupe périphérique 22 du bouton-poussoir deux nervures de renfort (non représentées), s'étendant axialement de part et d'autre de la nervure 281 et qui sont diamétralement opposées, ces nervures étant destinées à venir axialement en butée contre une couronne s'étendant axialement autour de la paroi transversale 12. Ces nervures de renfort permettent d'éviter le basculement du bouton-poussoir lorsque l'on appuie sur les côtés de la paroi supérieure 21 du bouton-poussoir. La couronne devra bien entendu comporter des échancrures qui autorisent l'enfoncement du bouton-poussoir en position de distribution.In storage position shown on the figure 4 the duct 14 closes the end 24a of the channel 24 so as to prevent any communication between the outlet orifice 51 and the inside of the distribution duct 14. The duct is thus sealed by the cooperation of two cylindrical pieces . In this position, the rib 281 abuts the abutment 190b. In addition, the tab 28 passes through the slot 19 and is located at the end of the opening 19 opposite the opening 19a. The lower end of the rib 281 formed on the push button is in axial abutment against the portion 160 of the annular transverse wall 16 so that if the user presses the push button 20, in particular on the zone of the upper wall 21 located opposite the dispensing orifice 51, it can not sink and can not actuate the valve 34. This prevents any involuntary actuation of the valve. It is also possible to provide on the inner surface of the peripheral skirt 22 of the push button two reinforcement ribs (not shown), extending axially on either side of the rib 281 and which are diametrically opposed, these ribs being intended to come axially in abutment against a ring extending axially around the transverse wall 12. These reinforcing ribs make it possible to prevent the push-button from tilting when the sides of the upper wall 21 of the button are pressed. button. The crown will of course have indentations that allow the depression of the push button in the dispensing position.

Pour distribuer le produit, l'utilisateur fait tourner le bouton-poussoir 20 autour de l'axe X de manière à positionner la flèche F en face de la marque "ON". Lors du mouvement de rotation du bouton-poussoir, la patte 27 se déplace dans l'ouverture en arc de cercle 18 et la patte 28 se déplace dans l'ouverture en arc de cercle 19 jusqu'à ce que l'épaulement 281a de la nervure 281 vienne contre la languette 191a et, du fait de son élasticité, la franchisse pour venir en butée contre la butée 190a en émettant un signal sonore permettant à l'utilisateur de savoir que le bouton-poussoir est placé dans la position de distribution. Dans cette position représentée à la figure 5, la nervure 281 se situe au-dessus de l'ouverture 19a et l'orifice de distribution 51 communique avec l'intérieur du conduit 14, via la fente 15a.To distribute the product, the user rotates the pushbutton 20 around the X axis so as to position the arrow F opposite the mark "ON". During the rotational movement of the push button, the tab 27 moves in the opening in a circular arc 18 and the tab 28 moves in the opening in an arc of circle 19 until the shoulder 281a of the rib 281 comes against the tongue 191a and, because of its elasticity, crosses it to abut against the stop 190a by emitting a sound signal allowing the user to know that the push button is placed in the dispensing position. In this position represented in figure 5 , rib 281 is above the opening 19a and the dispensing orifice 51 communicates with the interior of the duct 14, via the slot 15a.

L'utilisateur peut ensuite actionner la valve en appuyant sur le bouton-poussoir comme on l'a représenté à la figure 7. En appuyant sur la paroi supérieure 21, la nervure 281 de la patte 28 s'enfonce dans la portion d'ouverture 19a alors que la patte 27 reste accrochée à la paroi transversale 16 grâce au crochet 270. La jupe 23 se déplace alors selon un mouvement ayant une composante axiale et radiale en entraînant dans son mouvement le conduit 14, sur lequel elle est emmanchée, le mouvement du conduit étant possible grâce au fait que la paroi 12 se déforme. L'extrémité inférieure 14a du conduit exerce à son tour une pression sur la tige de valve 35 qui s'enfonce de manière à actionner la valve 34. Le produit contenu dans le récipient sort alors du récipient par le canal intérieur de la tige de valve et arrive à l'orifice de distribution 51 en passant par le conduit 14 et le canal 24. Lorsque l'utilisateur relâche le bouton-poussoir, la tige de valve remonte et la distribution du produit s'interrompt. Lorsque l'utilisateur ne souhaite plus pulvériser de produit, il tourne le bouton-poussoir de manière à le positionner à l'autre extrémité de l'ouverture 19.The user can then operate the valve by pressing the push button as shown in the figure 7 . By pressing on the upper wall 21, the rib 281 of the tab 28 sinks into the opening portion 19a while the tab 27 remains attached to the transverse wall 16 through the hook 270. The skirt 23 then moves in a movement having an axial component and radial driving in its movement the conduit 14, on which it is fitted, the movement of the conduit being possible due to the fact that the wall 12 is deformed. The lower end 14a of the conduit in turn exerts pressure on the valve stem 35 which sinks to actuate the valve 34. The product contained in the container then exits the container through the inner channel of the valve stem and arrives at the dispensing orifice 51 passing through the conduit 14 and the channel 24. When the user releases the pushbutton, the valve stem rises and the distribution of the product is interrupted. When the user no longer wishes to spray product, he turns the push-button so as to position it at the other end of the opening 19.

Lorsque l'utilisateur ne souhaite plus distribuer de produit, il fait tourner le bouton-poussoir 20 autour de l'axe X de manière à positionner la flèche F en face de la marque "OFF". Là encore, la patte 27 se déplace dans l'ouverture en arc de cercle 18 et la patte 28 se déplace dans l'ouverture en arc de cercle 19 jusqu'à ce que l'épaulement 281a de la nervure 281 franchisse la languette 191 b en émettant un signal sonore et que la nervure 281 vienne contre la butée 190b permettant à l'utilisateur de s'assurer que le bouton-poussoir est placé dans la position de stockage et ne risque plus d'être enfoncé.When the user no longer wishes to dispense product, he rotates the pushbutton 20 around the axis X so as to position the arrow F opposite the mark "OFF". Again, the tab 27 moves in the opening in a circular arc 18 and the tab 28 moves in the opening in a circular arc 19 until the shoulder 281a of the rib 281 crosses the tongue 191 b by emitting an audible signal and that the rib 281 comes against the stopper 190b allowing the user to ensure that the pushbutton is placed in the storage position and is no longer likely to be depressed.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après. On peut notamment prévoir d'ajouter un capot pour coiffer la tête de distribution, même s'il n'est pas indispensable.In the foregoing detailed description, reference has been made to preferred embodiments of the invention.
