Abstract

The head (12) has a base portion (13) e.g. hoop ring, fixed on a container (11) that is provided with a hollow distribution rod e.g. valve rod, and a lever (14) articulated on the base portion. The lever defines a control surface (15) located on a side of the head, and an end is carried by the lever that is connected to the base portion by a film-hinge. The end is coupled with the distribution rod, and communicates with a product discharge conduit (17) in forward direction (E). The base portion, lever and the end are molded with a single piece made of thermoplastic material. An independent claim is also included for a method for fabricating a gate-triggering distribution head.

Description

La présente invention concerne une tête de distribution pour un récipient pourvu d'une tige de distribution, par exemple une tige de valve ou de pompe.The present invention relates to a dispensing head for a container provided with a dispensing stem, for example a valve or pump stem.

Divers mécanismes de sécurité ont été proposés pour empêcher un actionnement accidentel de la tige de distribution, pendant le transport du récipient par exemple.Various safety mechanisms have been proposed to prevent accidental actuation of the dispensing rod, during the transport of the container for example.

La demande FR 2 692 559 divulgue ainsi une tête de distribution comportant un bouton-poussoir ayant un embout accouplé avec la tige de distribution, le bouchon-poussoir étant mobile relativement à une coiffe fixée sur le récipient, sur laquelle est articulée un organe de blocage de la tige de distribution, déplaçable entre une position active empêchant l'enfoncement de la tige de distribution et une position inactive autorisant l'enfoncement de la tige de distribution. Cette dernière est réalisée avec une gorge et l'organe de blocage se présente sous la forme d'un disque traversé par une ouverture dans laquelle est engagée la tige de distribution. Une extrémité de cette ouverture est suffisamment étroite pour que le disque puisse s'engager dans la gorge et bloquer ainsi l'enfoncement de la tige de distribution. Un tel mécanisme est relativement complexe, nécessitant une tige de distribution pourvue d'une gorge et l'assemblage de plusieurs pièces fabriquées séparément.Requirement FR 2,692,559 discloses a dispensing head comprising a push-button having a tip coupled to the dispensing rod, the push-plug being movable relative to a cap attached to the container, on which is articulated a locking member of the dispensing rod, movable between an active position preventing the depression of the dispensing rod and an inactive position allowing the depression of the dispensing rod. The latter is made with a groove and the locking member is in the form of a disc traversed by an opening in which is engaged the dispensing rod. One end of this opening is narrow enough that the disc can engage the groove and thus block the depression of the dispensing rod. Such a mechanism is relatively complex, requiring a distribution rod provided with a groove and the assembly of several parts manufactured separately.

US 5 282 551 divulgue un organe de blocage réalisé d'une seule pièce avec une partie de base fixée sur le récipient, l'organe de blocage étant relié à cette dernière par des ponts de matière élastiquement déformables. L'organe de blocage est déplaçable en translation et doit être actionné simultanément au bouton-poussoir, ce qui n'est pas très confortable pour l'utilisateur. US 5,282,551 discloses a locking member made in one piece with a base portion attached to the container, the locking member being connected thereto by bridges of elastically deformable material. The locking member is movable in translation and must be actuated simultaneously with the push button, which is not very comfortable for the user.

On connaît par ailleurs de EP 1 661 822 A1 , US 6 286 723 B1 , US 6 003 739 , US 2003/0192910 A1 , US 4 441 633 , US 2006/0113327 A1 et WO 01/36275 des têtes de distribution dans lesquelles la surface de commande, sur laquelle l'utilisateur doit appuyer pour déclencher la distribution, se situe non pas sur le dessus de la tête de distribution mais sur un levier, sur le côté de la tête de distribution. De telles têtes de distribution sont encore appelées à déclenchement par « gâchette » et sont pour la plupart de construction relativement complexe, donc coûteuse.We also know from EP 1 661 822 A1 , US 6,286,723 B1 , US 6,003,739 , US 2003/0192910 A1 , US 4,441,633 , US 2006/0113327 A1 and WO 01/36275 dispensing heads in which the control surface, on which the user must press to trigger dispensing, is not on the top of the dispensing head but on a lever on the side of the dispensing head. Such dispensing heads are still called triggers trigger "and are mostly relatively complex construction, so expensive.

EP 1 661 822 A1 apporte une certaine simplification à la fabrication de la tête grâce à son moulage en une seule pièce. Toutefois, la mise en place sur le récipient est relativement complexe et la première utilisation nécessite de rompre des ponts de matière, ce qui demande une poussée plus importante sur le levier de commande. EP 1 661 822 A1 brings a certain simplification to the manufacture of the head thanks to its molding in one piece. However, the implementation on the container is relatively complex and the first use requires breaking bridges of material, which requires a greater thrust on the control lever.

Il existe un besoin pour perfectionner encore les têtes de distribution afin notamment d'en simplifier la fabrication et en diminuer le coût.There is a need to further improve the distribution heads in particular to simplify the manufacture and reduce the cost.

L'invention a pour objet, selon l'un de ses aspects, une tête de distribution pour un récipient pourvu d'une tige de distribution, comportant :

  • une partie de base configurée pour se fixer sur le récipient,
  • un levier articulé sur la partie de base, de préférence par une charnière film,
  • un embout porté par le levier, venu de moulage avec le levier, l'embout étant configuré pour s'accoupler avec la tige de distribution et communiquant avec au moins un orifice d'éjection du produit.
The object of the invention is, according to one of its aspects, a dispensing head for a container provided with a dispensing rod, comprising:
  • a base portion configured to attach to the container,
  • a lever articulated on the base part, preferably by a film hinge,
  • a tip carried by the lever, molded with the lever, the nozzle being configured to mate with the dispensing rod and communicating with at least one ejection port of the product.

Autrement dit, l'invention a pour objet selon un de ses aspects, une tête de distribution pour récipient pourvu d'une tige de distribution à commande par enfoncement et/ou basculement, comportant :

  • une partie de base configurée pour se fixer sur le récipient,
  • un levier articulé sur la partie de base,
  • un embout configuré pour s'accoupler à la tige de distribution et communiquant avec au moins un orifice d'éjection de produit,
  • au moins un pont de matière reliant l'embout au levier présent au moins avant que l'embout soit accouplé à ladite tige et au moins avant un premier actionnement du levier.
In other words, the object of the invention is, in one of its aspects, a dispensing head for a container provided with a push-in and / or tilt-controlled dispensing rod, comprising:
  • a base portion configured to attach to the container,
  • a lever articulated on the base part,
  • a tip configured to mate with the dispensing stem and communicating with at least one product ejection port,
  • at least one bridge of material connecting the tip to the lever present at least before the tip is coupled to said rod and at least before a first actuation of the lever.

Le produit peut être distribué autrement que dans l'axe longitudinal de la tige de distribution ou dans l'axe longitudinal du récipient, transversalement à l'axe de la tige de distribution ou à l'axe longitudinal du récipient.The product may be dispensed otherwise than in the longitudinal axis of the dispensing rod or in the longitudinal axis of the container, transverse to the axis of the dispensing rod or to the longitudinal axis of the container.

Ledit au moins un pont de matière est distinct de l'articulation entre le levier et la partie de base.Said at least one material bridge is distinct from the articulation between the lever and the base part.

Ainsi, selon un aspect de l'invention, d'une part le levier et l'embout, et d'autre part la partie de base, se situent en configuration de sortie de moule d'un côté et de l'autre d'une articulation, par exemple réalisée sous la forme d'une charnière film.Thus, according to one aspect of the invention, on the one hand the lever and the tip, and on the other hand the base part, are in the mold exit configuration on one side and the other side. a hinge, for example made in the form of a film hinge.

Une telle tête de distribution peut être réalisée facilement, hormis une éventuelle buse de pulvérisation rapportée, d'une seule pièce par moulage de matière, ce qui en réduit le coût.Such a dispensing head can be easily achieved, except for a possible spray nozzle reported in one piece by molding material, which reduces the cost.

La tige de distribution du récipient peut être à commande par enfoncement et/ou par basculement. Lorsque la tige de distribution est à commande par enfoncement, elle est déplacée parallèlement à son axe longitudinal, qui peut être confondu avec l'axe longitudinal du récipient.The dispensing stem of the container may be driven by depression and / or tilting. When the dispensing rod is driving-driven, it is moved parallel to its longitudinal axis, which may coincide with the longitudinal axis of the container.

L'embout peut être relié au levier par l'intermédiaire d'au moins un pont de matière flexible. Le ou les ponts de matière flexible peuvent avantageusement se déformer lorsque le levier est actionné pour agir sur la tête de distribution. Le ou les pont(s) de matière, non sécables, se déforment par exemple en torsion, par exemple autour d'un axe parallèle à l'axe d'articulation du levier.The tip can be connected to the lever via at least one bridge of flexible material. The one or more flexible material bridges may advantageously deform when the lever is actuated to act on the dispensing head. The bridge (s) of material, not breakable, deform for example in torsion, for example around an axis parallel to the hinge axis of the lever.

Dans le cas où ledit au moins un pont de matière est sécable, la paroi de dessus du levier peut comprendre une partie formant casquette, ou bride, s'étendant au moins en partie au-dessus de la portion d'éjection de l'embout et apte à venir en appui sur cette portion d'éjection lors d'un actionnement du levier de façon à solliciter le déplacement de la tige de distribution.In the case where said at least one material bridge is breakable, the upper wall of the lever may comprise a cap portion, or flange, extending at least partly above the ejection portion of the nozzle. and able to bear against this ejection portion when the lever is actuated so as to urge the displacement of the dispensing rod.

Dans un exemple de mise en oeuvre de l'invention, le levier définit une surface d'actionnement sur laquelle l'utilisateur peut appuyer pour provoquer la distribution; cette surface d'actionnement peut être située à proximité de l'extrémité du levier opposée à son axe géométrique d'articulation sur la partie de base. Ainsi, la tête de distribution peut être actionnée à la manière d'une tête de distribution à déclenchement par « gâchette ». Pour déclencher la distribution, l'utilisateur exerce une force sur le levier qui tend à le faire pivoter, cette force ayant une composante non nulle orientée perpendiculairement à l'axe longitudinal du récipient. La surface de commande peut se rapprocher de l'axe de la tige de distribution au cours du mouvement causé par l'utilisateur pour actionner la tige de distribution.In an exemplary implementation of the invention, the lever defines an actuating surface on which the user can press to cause dispensing; this actuating surface may be located near the end of the lever opposite its geometric axis of articulation on the base portion. Thus, the dispensing head can be actuated in the manner of a trigger trigger dispensing head. To trigger the dispensing, the user exerts a force on the lever that tends to rotate it, this force having a non-zero component oriented perpendicularly to the longitudinal axis of the container. The control surface may move closer to the axis of the dispensing stem during the movement caused by the user to actuate the dispensing stem.

Dans un exemple de mise en oeuvre de l'invention, le levier porte deux montants entre lesquels s'étend au moins partiellement l'embout, les ponts de matière flexibles précités se raccordant chacun à un montant respectif.In an exemplary implementation of the invention, the lever carries two uprights between which the nozzle extends at least partially, the aforementioned flexible material bridges each being connected to a respective amount.

Dans un exemple de mise en oeuvre de l'invention, le levier porte au moins un premier relief et la partie de base au moins un deuxième relief, sur lequel le premier relief peut s'encliqueter pour maintenir le levier dans une configuration rabattue sur la partie de base. Ce premier relief est par exemple porté par un conduit comportant l'embout et amenant le produit jusqu'à le ou les orifice(s) d'éjection.In an exemplary implementation of the invention, the lever carries at least a first relief and the base portion at least a second relief, on which the first relief can snap to hold the lever in a folded configuration on the base portion. This first relief is for example carried by a conduit having the nozzle and bringing the product to the orifice (s) ejection (s).

La tête de distribution peut comporter une buse de pulvérisation rapportée, notamment fixée à une extrémité du conduit précité.The dispensing head may comprise an attached spray nozzle, in particular attached to one end of the aforementioned conduit.

La partie de base, le levier et l'embout sont avantageusement moulés d'une seule pièce dans une matière thermoplastique.The base part, the lever and the tip are advantageously molded in one piece in a thermoplastic material.

La tête de distribution peut avantageusement s'inscrire dans l'enveloppe du récipient lorsque ce dernier est observé selon son axe. Cela permet d'éviter que la tête de distribution ne gêne le convoyage des récipients au sein de la chaîne de fabrication. En particulier, l'enveloppe du récipient peut être cylindrique et l'intégralité de la tête de distribution, donc y compris le levier et la portion d'éjection du produit, peut s'inscrire dans ce cylindre lorsque le récipient est observé selon l'axe dudit cylindre.The dispensing head may advantageously fit into the envelope of the container when the latter is observed along its axis. This makes it possible to prevent the dispensing head from interfering with the conveying of containers within the production line. In particular, the shell of the container may be cylindrical and the entire dispensing head, including the lever and the ejection portion of the product, may fit in this cylinder when the container is observed according to the axis of said cylinder.

Le levier peut comporter une ouverture située en regard du conduit de distribution comportant l'embout, voire traversée par le conduit. La présence de l'ouverture peut permettre, le cas échéant, une certaine mobilité du conduit relativement au levier, lors de l'actionnement de celui-ci.The lever may comprise an opening located opposite the distribution duct comprising the nozzle, or even through the duct. The presence of the opening may allow, if necessary, a certain mobility of the conduit relative to the lever, when actuating it.

Dans un exemple de mise en oeuvre de l'invention, la tête de distribution comporte un organe de blocage configuré pour prendre une position active où il s'oppose à l'enfoncement de la tige de distribution et une position inactive où il permet l'enfoncement de la tige de distribution lors de l'actionnement du levier, l'organe de blocage étant mobile relativement à la partie de base et étant porté par cette dernière.In an exemplary implementation of the invention, the dispensing head comprises a locking member configured to take an active position where it opposes the depression of the dispensing rod and an inactive position where it allows the depressing the distribution rod during actuation of the lever, the locking member being movable relative to the base portion and being carried by the latter.

L'organe de blocage peut conserver la position où il est laissé par l'utilisateur.The locking member may retain the position where it is left by the user.

L'organe de blocage est avantageusement relié par une articulation à la partie de base, étant de préférence moulé d'une seule pièce avec celle-ci. L'organe de blocage se raccorde par exemple à une surface radialement intérieure de la partie de base, notamment lorsque celle-ci présente une forme annulaire.The locking member is advantageously connected by a hinge to the base portion, preferably being molded in one piece therewith. The locking member is connected for example to a radially inner surface of the base portion, especially when it has an annular shape.

L'organe de blocage peut comporter un ajour ou une encoche ouverte latéralement pour le passage de la tige de distribution du récipient, cette encoche ayant un bord configuré pour s'encliqueter sur la tige de distribution lors du passage de l'organe de blocage de la position inactive à la position active. Ainsi, la tige de distribution peut coopérer avec l'organe de blocage d'une part pour faire ressentir à l'utilisateur le passage de la position active à la position inactive et inversement et d'autre part pour maintenir l'organe de blocage dans la configuration où il est laissé par l'utilisateur. L'ajour ou l'encoche peut comporter des première et deuxième portions de bord épousant sensiblement la forme de la tige de distribution, ces première et deuxième portions étant par exemple des arcs de cercles de même rayon mais de centres décalés. Ces portions peuvent définir entre elles une arête servant à l'encliquetage. L'ajour peut présenter un contour fermé, par exemple en forme générale de huit. L'ajour peut présenter deux arêtes opposées délimitant les deux portions circulaires du huit, qui sont franchies avec déformation élastique par la tige de distribution lors du passage de la position active vers la position inactive et inversement. Chaque portion peut présenter un diamètre sensiblement égal à celui de la tige de distribution.The locking member may comprise an opening or notch open laterally for the passage of the dispensing rod of the container, this notch having an edge configured to snap onto the dispensing stem during the passage of the locking member of the container. the inactive position at the active position. Thus, the distribution rod can cooperate with the locking member on the one hand to make the user feel the passage from the active position to the inactive position and vice versa and secondly to maintain the locking member in the configuration where it is left by the user. The ajour or the notch may comprise first and second edge portions substantially conforming to the shape of the dispensing rod, these first and second portions being for example arcs of circles of the same radius but offset centers. These portions may define between them an edge for snapping. The opening may have a closed contour, for example in the general shape of eight. The opening may have two opposite edges delimiting the two circular portions of the eight, which are crossed with elastic deformation by the dispensing rod during the passage of the active position to the inactive position and vice versa. Each portion may have a diameter substantially equal to that of the dispensing rod.

L'organe de blocage peut présenter des première et deuxième régions situées par exemple à des hauteurs différentes, par exemple des régions d'épaisseurs différentes, la deuxième région étant par exemple plus épaisse que la première, la deuxième région se superposant à une tranche d'extrémité de l'embout lorsque l'organe de blocage est en position de blocage pour empêcher l'enfoncement de l'embout d'une course suffisante pour provoquer la distribution et seule la première région se superposant à la tranche d'extrémité de l'embout lorsque l'organe de blocage est en position inactive, l'enfoncement de l'embout n'étant plus contrarié par la deuxième région. Ainsi, l'embout peut être empêché de s'enfoncer par l'organe de blocage malgré l'utilisation d'une tige de distribution de type conventionnel, sans gorge pour l'accrochage de l'organe de blocage, contrairement à FR 2 692 559 discuté plus haut.The locking member may have first and second regions located for example at different heights, for example regions of different thicknesses, the second region being for example thicker than the first, the second region being superimposed on a wafer. end of the tip when the locking member is in the locking position to prevent the insertion of the tip of a stroke sufficient to cause the distribution and only the first region superimposed on the end portion of the end piece when the locking member is in the inactive position, the depression of the end piece being no longer disturbed by the second region. Thus, the tip can be prevented from being pushed in by the blocking member despite the use of a conventional type of distribution rod, without groove for fastening the locking member, contrary to FR 2,692,559 discussed above.

L'organe de blocage peut comporter deux montants externes définissant des surfaces de poussée sur lesquelles l'utilisateur peut appuyer pour le faire passer de la position active à la position inactive et inversement. Ces montants peuvent être incurvés à leur base, étant par exemple concaves l'un vers l'autre et vers la tige de distribution, d'autres formes étant cependant possibles. L'organe de blocage et/ou la partie de base peut comporter une inscription, par exemple « ON » ou « OFF », imprimée et/ou moulée en relief ou portée par une étiquette rapportée, pour renseigner l'utilisateur sur le caractère actif ou inactif de l'organe de blocage selon sa position relativement à la partie de base.The locking member may comprise two external uprights defining pushing surfaces on which the user can press to move it from the active position to the inactive position and vice versa. These amounts may be curved at their base, being for example concave towards each other and towards the dispensing rod, other forms being however possible. The locking member and / or the base part may comprise an inscription, for example "ON" or "OFF", printed and / or molded in relief or carried by an attached label, to inform the user on the active character or inactive of the locking member according to its position relative to the base part.

Le levier peut s'étendre au moins partiellement au dessus des montants ci-dessus.The lever may extend at least partially above the above amounts.

La course angulaire de l'organe de blocage peut être limitée, au moins dans un sens, par butée de l'organe de blocage contre la partie de base. La course angulaire de l'organe de blocage peut être limitée, dans le sens opposé, par butée de la tige de distribution dans le fond d'une encoche de l'organe de blocage.The angular travel of the locking member may be limited, at least in one direction, by abutment of the locking member against the base portion. The angular stroke of the locking member may be limited, in the opposite direction, by abutment of the dispensing rod in the bottom of a notch of the locking member.

La partie de base peut être configurée pour s'encliqueter sur le récipient ou pour se fixer dessus différemment, par exemple par vissage ou collage. La partie de base peut encore être venue d'une seule pièce avec une portion au moins du récipient, le cas échéant.The base portion may be configured to snap onto or otherwise attach to the container, such as by screwing or gluing. The base portion may have come from a single piece with at least a portion of the container, if any.

L'invention a encore pour objet, selon un autre de ses aspects, un dispositif comportant un récipient et une tête de distribution telle que définie ci-dessus, fixée sur le récipient.The invention further relates, in another of its aspects, a device comprising a container and a dispensing head as defined above, fixed on the container.

Le récipient est par exemple un bidon aérosol.The container is for example an aerosol can.

Le récipient peut contenir un produit cosmétique, y compris de soin, ou un produit non cosmétique, par exemple un produit ménager.The container may contain a cosmetic product, including a care product, or a non-cosmetic product, for example a household product.

L'invention a encore pour objet un procédé de fabrication d'une tête de distribution, comportant les étapes suivantes :

  • mouler d'une seule pièce la partie de base, le levier et l'embout, alors que le levier n'est pas dans sa configuration d'utilisation,
  • rabattre le levier sur la partie de base pour l'amener dans sa configuration d'utilisation, le déplacement du levier s'accompagnant de celui de l'embout, qui lui est solidaire.
The invention also relates to a method of manufacturing a dispensing head, comprising the following steps:
  • mold in one piece the base part, the lever and the bit, while the lever is not in its configuration of use,
  • fold the lever on the base part to bring it into its configuration of use, the movement of the lever being accompanied by that of the end piece, which is secured to it.

La tête peut être moulée avec l'organe de blocage en configuration active. Cela évite l'actionnement de la tige de distribution lors du montage de la tête sur le récipient.The head can be molded with the blocking member in active configuration. This avoids the actuation of the dispensing rod when mounting the head on the container.

Le dispositif de conditionnement et de distribution 10 représenté à la figure 1 comporte un récipient 11, par exemple un bidon aérosol, et une tête de distribution 12 fixée sur ce récipient 11, en l'espèce rapportée dessus dans l'exemple considéré.The packaging and dispensing device 10 shown in FIG. figure 1 comprises a container 11, for example an aerosol can, and a dispensing head 12 fixed on this container 11, in this case reported above in the example in question.

Le récipient 11 comporte une valve comprenant une tige creuse de distribution 33, visible sur la figure 4, à commande par enfoncement, par laquelle le produit est distribué. La valve comporte un organe de rappel de la tige de distribution.The container 11 comprises a valve comprising a hollow dispensing rod 33, visible on the figure 4 , driven by depression, by which the product is dispensed. The valve comprises a return member of the dispensing rod.

La valve peut être de tout type conventionnel pour bidon aérosol.The valve can be of any conventional type for aerosol can.

La tête de distribution 12 comporte une partie de base 13, encore appelée « frette », servant à la fixation sur le récipient 11 et un levier de commande 14 articulé sur la partie de base 13 autour d'un axe géométrique de rotation R, le levier 14 définissant une surface d'actionnement, également désignée par surface de commande 15, sur laquelle l'utilisateur peut appuyer pour provoquer la distribution du produit contenu dans le récipient. Cette surface de commande 15 est située à l'avant du levier 14, sur le côté de la tête de distribution 12, cette dernière étant du type à déclenchement par « gâchette ». La surface de commande 15 est orientée vers l'avant.The dispensing head 12 has a base portion 13, also called "hoop", for fixing on the container 11 and a control lever 14 articulated on the base portion 13 about a geometric axis of rotation R, the lever 14 defining an actuating surface, also designated by control surface 15, on which the user can press to cause the dispensing of the product contained in the container. This control surface 15 is located at the front of the lever 14, on the side of the dispensing head 12, the latter being of the "trigger" type. The control surface 15 is oriented towards the front.

La tête de distribution 12 comporte un conduit 17 permettant l'éjection du produit à pulvériser dans une direction E, vers l'avant. La direction E est généralement perpendiculaire à l'axe longitudinal du récipient. Ce conduit 17 comporte dans l'exemple illustré une portion qui forme un embout de raccordement 20 qui est accouplé à la tige de distribution 33, qui s'étend sensiblement parallèlement à celle-ci, et une portion d'éjection qui s'étend sensiblement perpendiculairement à l'axe de l'embout 20. Le conduit 17 peut avoir une portion d'éjection qui s'étend perpendiculairement à l'embout 20. L'embout 20 définit un logement 21 évasé vers le bas pour recevoir la tige 33, ce logement 21 étant délimité supérieurement par un épaulement 23 contre lequel la tige 33 peut venir en butée, comme on peut le voir sur la figure 5.The dispensing head 12 comprises a conduit 17 for ejection of the product to be sprayed in a direction E, forwards. The direction E is generally perpendicular to the longitudinal axis of the container. This duct 17 comprises in the illustrated example a portion which forms a connecting piece 20 which is coupled to the dispensing rod 33, which extends substantially parallel thereto, and an ejection portion which extends substantially perpendicularly to the axis of the nozzle 20. The conduit 17 may have an ejection portion extending perpendicularly to the nozzle 20. The nozzle 20 defines a housing 21 flared downward to receive the rod 33, this housing 21 being defined upper by a shoulder 23 against which the rod 33 can abut, as can be seen on the figure 5 .

Le conduit 17 comporte à son extrémité avant un logement annulaire 26 pour recevoir une buse de distribution, connue en elle-même et non représentée, par exemple une buse à canaux tourbillonnaires ou de type autre. Cette buse est alimentée par un canal 28 du conduit 17, dans l'exemple illustré.The conduit 17 comprises at its front end an annular housing 26 for receiving a dispensing nozzle, known in itself and not shown, for example a swirling channel nozzle or of another type. This nozzle is fed by a channel 28 of the conduit 17, in the illustrated example.

La fixation de la partie de base 13 sur le récipient 11 peut s'effectuer de diverses manières et la partie de base 13 comporte par exemple, comme illustré, un bourrelet annulaire 30 configuré pour s'encliqueter dans une gorge correspondante du récipient, par exemple une gorge formée par une coupelle du récipient portant la valve.The attachment of the base portion 13 to the container 11 can be effected in various ways and the base portion 13 comprises for example, as illustrated, an annular bead 30 configured to snap into a corresponding groove of the container, for example a groove formed by a cup of the container carrying the valve.

Le levier 14 est articulé sur la partie de base 13 autour de l'axe R par une charnière film 35, étant moulé d'une seule pièce avec la partie de base 13 dans une configuration ouverte, représentée à la figure 3.The lever 14 is hinged to the base portion 13 about the axis R by a film hinge 35, being molded in one piece with the base portion 13 in an open configuration, shown in FIG. figure 3 .

L'axe de rotation R est par exemple perpendiculaire à l'axe longitudinal du récipient 11.The axis of rotation R is for example perpendicular to the longitudinal axis of the container 11.

Le levier 14 comporte des premiers reliefs 40, tels que des dents, configurés pour s'encliqueter sur des deuxièmes reliefs 41 réalisés avec la partie de base 13, de manière à retenir par encliquetage le levier 14 rabattu sur la partie de base 13.The lever 14 comprises first reliefs 40, such as teeth, configured to snap onto second reliefs 41 made with the base portion 13, so as to snap-fasten the lever 14 folded onto the base portion 13.

Cette dernière comporte un montant 43, ayant une section transversale généralement en forme de U, dont le dos porte la charnière film 35 et dont les ailes latérales comportent à leur extrémité supérieure des rebords d'accrochage constituant les deuxième reliefs 41 et formant saillie l'un vers l'autre. Des ouvertures 45 sont réalisées dans la partie de base 13 pour permettre le moulage de ces rebords d'accrochage.The latter comprises an upright 43, having a generally U-shaped cross section, whose back carries the film hinge 35 and whose lateral wings have at their upper end hooking flanges constituting the second reliefs 41 and forming a projection. one to the other. Openings 45 are made in the base portion 13 to allow the molding of these attachment flanges.

L'embout 20 est porté par deux montants 51 qui se raccordent supérieurement à une paroi de dessus 52 du levier 14. Ce dernier comporte également deux ailes latérales 57 qui prolongent vers le bas la paroi de dessus 52. L'embout 20 et les montants 51 s'étendent au moins partiellement dans la concavité formée par les deux ailes 57 et la paroi de dessus 52.The tip 20 is carried by two uprights 51 which are connected superiorly to a top wall 52 of the lever 14. The latter also has two lateral wings 57 which extend downwardly the top wall 52. The tip 20 and the uprights 51 extend at least partially in the concavity formed by the two wings 57 and the top wall 52.

La paroi de dessus 52 est traversée par une ouverture 55 dans laquelle s'étend le conduit 17. L'ouverture 55 s'étend également à l'avant du levier 14 afin de permettre au conduit 17 de faire saillie vers l'avant par rapport à la surface de commande 15, comme on peut le voir sur la figure 2.The top wall 52 is traversed by an opening 55 in which the duct 17 extends. The opening 55 also extends forwardly of the lever 14 so as to allow the duct 17 to protrude forwardly relative to the control surface 15, as can be seen on the figure 2 .

Le conduit d'éjection 17 et la surface de commande 15 du levier 14 peuvent être disposés comme illustré sensiblement l'un au dessus de l'autre et sur le côté de la partie de base 13. L'extrémité inférieure du levier peut, comme illustré, se situer au dessus du plan perpendiculaire à l'axe de la tige de distribution et contenant l'extrémité inférieure de la partie de base.The ejection duct 17 and the control surface 15 of the lever 14 may be arranged as illustrated substantially one above the other and on the side of the base portion 13. The lower end of the lever may, as shown, lie above the plane perpendicular to the axis of the dispensing rod and containing the lower end of the base portion.

Le levier 14 vu de côté, par exemple comme sur la figure 2, peut avoir de manière non limitative une forme d'arche remontant au dessus du niveau de la charnière 35 et redescendant au dessous du niveau de la charnière, de manière à avoir la surface de commande 15 à un niveau inférieur à celui de l'orifice d'éjection, dans une position d'utilisation où le récipient a la tige de distribution verticale vers le haut. La surface de commande est par exemple orientée vers l'avant, dans la position d'utilisation.The lever 14 seen from the side, for example as on the figure 2 , may have in a nonlimiting manner an arch form rising above the level of the hinge 35 and descending below the level of the hinge, so as to have the control surface 15 at a level lower than that of the orifice ejection, in a use position where the container has the vertical dispensing rod upwards. The control surface is for example oriented forward in the position of use.

L'utilisateur tenant le récipient dans sa main peut activer la gâchette en appuyant avec l'index, vers le récipient. La force exercée par l'utilisateur et la direction de projection du produit sont par exemple sensiblement à l'opposé l'une de l'autre. La force appliquée sur la surface de commande a par exemple une composante non nulle appartenant à un plan perpendiculaire à l'axe longitudinal du récipient 11, c'est-à-dire une composante horizontale non nulle lorsque le récipient est tenu debout.The user holding the container in his hand can activate the trigger by pressing with the index finger towards the container. The force exerted by the user and the direction of projection of the product are for example substantially opposite to each other. The force applied to the control surface has, for example, a non-zero component belonging to a plane perpendicular to the longitudinal axis of the container 11, that is to say a non-zero horizontal component when the container is held upright.

L'embout 20 se raccorde aux montants 51 par des ponts de matière flexibles 58, ces ponts de matière 58 ayant dans l'exemple illustré une section transversale circulaire, et étant d'axe Z parallèle à l'axe de rotation R.The tip 20 is connected to the uprights 51 by flexible material bridges 58, these material bridges 58 having in the example illustrated a circular cross section, and being of Z axis parallel to the axis of rotation R.

Lorsque l'utilisateur appuie sur la surface de commande 15, le levier 14 peut pivoter relativement à la partie de base 13 vers le bas, tendant à entraîner également vers le bas l'embout 20 par l'intermédiaire des montants 51 et des ponts de matière 58. Ces derniers peuvent se déformer en torsion autour de l'axe Z pour permettre à l'embout 20 de rester sensiblement parallèle à l'axe de la tige de distribution 33 au cours de l'enfoncement de celle-ci. La torsion des ponts permet à l'embout 20 de pivoter par rapport au levier 14.When the user presses on the control surface 15, the lever 14 can pivot relative to the base part 13 downwards, tending also to drive the end piece 20 via the uprights 51 and material 58. These can be deformed in torsion about the Z axis to allow the tip 20 to remain substantially parallel to the axis of the dispensing rod 33 during the depression thereof. The torsion of the bridges allows the tip 20 to pivot relative to the lever 14.

Lorsque l'utilisateur relâche le levier 14, la force de rappel à laquelle est soumise la tige de distribution 33 rappelle l'embout 20 et le levier 14 vers le haut.When the user releases the lever 14, the return force to which the dispensing rod 33 is subjected recalls the tip 20 and the lever 14 upwards.

Afin d'éviter un actionnement accidentel de la tige de distribution 12, cette dernière comporte avantageusement, comme cela va maintenant être décrit, un mécanisme de sécurité permettant de bloquer sélectivement l'actionnement de la tige de distribution 33.In order to avoid accidental actuation of the dispensing rod 12, the latter advantageously comprises, as will now be described, a safety mechanism for selectively blocking the actuation of the dispensing rod 33.

Dans l'exemple illustré aux figures 1 à 7, ce mécanisme comporte un organe de blocage 60 qui est relié à la partie de base 13 par une articulation 61 d'axe K, venue de moulage avec la partie de base 13 et avec l'organe de blocage 60. L'axe K est parallèle à la direction d'enfoncement de la tige de distribution 33.In the example shown in Figures 1 to 7 this mechanism comprises a locking member 60 which is connected to the base portion 13 by a hinge 61 of axis K, integrally molded with the base portion 13 and with the locking member 60. The axis K is parallel to the direction of insertion of the distribution rod 33.

L'organe de blocage 60 peut pivoter entre une première position où il permet l'actionnement de la tige de distribution 33, dite « inactive » (ou « déverrouillée ») et une deuxième position où il bloque cet actionnement, dite « active » (ou de « verrouillage »).The locking member 60 can pivot between a first position where it allows the actuation of the dispensing rod 33, called "inactive" (or "unlocked") and a second position where it blocks this actuation, called "active" ( or "lock").

L'organe de blocage 60 comporte une encoche 62, ouverte latéralement comme on peut le voir sur la figure 4 notamment, dont le bord comporte une première portion 63 et une deuxième portion 64, toutes deux circulaire de rayon adapté à celui de la tige de distribution 33 et de centres décalés, ces portions 63 et 64 définissant à leur jonction une arête 65 qui peut franchir avec encliquetage la tige de commande 33 lorsque l'organe de blocage 60 passe de la position active à la position inactive et inversement.The locking member 60 has a notch 62, open laterally as can be seen on the figure 4 in particular, whose edge comprises a first portion 63 and a second portion 64, both circular with a radius adapted to that of the distribution rod 33 and shifted centers, these portions 63 and 64 defining at their junction a ridge 65 which can cross with latching the control rod 33 when the locking member 60 moves from the active position to the inactive position and vice versa.

L'organe de blocage 60 présente une épaisseur variable, avec une nervure 68 qui peut venir en appui contre la tranche d'extrémité inférieure 70 de l'embout 20 lorsque l'organe de blocage 60 est en position active, comme illustré à la figure 6, afin d'empêcher le déplacement vers le bas de l'embout 20 et l'actionnement de la tige 33.The locking member 60 has a variable thickness, with a rib 68 which can bear against the lower end edge 70 of the end piece 20 when the locking member 60 is in the active position, as illustrated in FIG. figure 6 , in order to prevent the downward movement of the tip 20 and the actuation of the rod 33.

Lorsque l'organe de blocage 60 est en position inactive, cette nervure 68 ne se superpose plus avec la tranche d'extrémité inférieure 70 de l'embout 20 et ce dernier peut se déplacer vers le bas d'une course suffisante pour actionner la tige de commande 33 afin de provoquer la distribution du produit.When the locking member 60 is in the inactive position, this rib 68 is no longer superimposed with the lower end edge 70 of the tip 20 and the latter can move down a sufficient stroke to actuate the rod 33 to cause the distribution of the product.

L'organe de blocage 60 comporte deux montants externes 73 et 74 opposés, sur lesquels l'utilisateur peut appuyer pour déplacer l'organe de blocage 60 entre les positions active et inactive.The locking member 60 has two external uprights 73 and 74 opposite, on which the user can press to move the locking member 60 between the active and inactive positions.

Dans l'exemple illustré, ces montants présentent à leur base une forme incurvée, étant concaves l'un vers l'autre.In the illustrated example, these amounts have at their base a curved shape, being concave towards one another.

Pour amener l'organe de blocage 60 en position active, l'utilisateur appuie sur le montant 73, ce qui force la tige de distribution 33 à franchir l'arête 65 et à se loger dans le fond de l'encoche 62. Dans cette configuration, l'enfoncement de l'embout 20 est empêché par la nervure 68.To bring the locking member 60 into the active position, the user presses on the upright 73, which forces the dispensing rod 33 to cross the ridge 65 and to lodge in the bottom of the notch 62. configuration, the depression of the tip 20 is prevented by the rib 68.

Afin de pouvoir distribuer du produit, l'utilisateur appuie en sens inverse sur le montant 74, ce qui amène la tige de commande 33 en regard de la portion 64 du bord de l'encoche 32 et éloigne la nervure 68 de la tranche d'extrémité inférieure 70 de l'embout 20, ce qui permet à ce dernier de s'enfoncer suffisamment pour actionner la tige de distribution 33.In order to be able to dispense with the product, the user presses on the upright 74 in the opposite direction, which brings the control rod 33 facing the portion 64 of the edge of the notch 32 and moves the rib 68 away from the slice. lower end 70 of the nozzle 20, which allows the latter to sink sufficiently to actuate the dispensing rod 33.

Dans la variante illustrée aux figures 8 à 13, la tête de distribution 12 est réalisée un peu différemment. Les mêmes signes de référence ont été conservés pour désigner des éléments identiques ou ayant la même fonction que dans l'exemple précédemment décrit.In the variant illustrated in Figures 8 to 13 , the dispensing head 12 is made a little differently. The same reference signs have been retained to designate elements that are identical or have the same function as in the example previously described.

Dans cet exemple, l'organe de blocage 60 se présente sous la forme générale d'une ancre dont l'utilisateur peut actionner les extrémités 81 et 82, de manière à le déplacer entre les positions active et inactive.In this example, the locking member 60 is in the general form of an anchor which the user can actuate the ends 81 and 82, so as to move between the active and inactive positions.

Le maintien du levier 14 en position rabattue s'effectue dans cet exemple par une patte de retenue 93 portée par le conduit 17, qui s'encliquette sur un relief 95 de la partie de base, située à l'opposé de la charnière 35. Le levier 14 est réalisé avec une ouverture 96 qui permet le moulage de cette patte de retenue 93.The holding of the lever 14 in the folded position is effected in this example by a retaining tab 93 carried by the duct 17, which snaps onto a relief 95 of the base part, located opposite the hinge 35. The lever 14 is made with an opening 96 which allows the molding of this retaining tab 93.

Dans cet exemple également, l'embout 20 se raccorde directement au levier 14 entre les branches de celui-ci délimitant latéralement l'ouverture 55, par les ponts flexibles 58.In this example also, the end piece 20 connects directly to the lever 14 between the branches thereof laterally delimiting the opening 55, by the flexible bridges 58.

Sur la figure 10, on voit que l'organe de blocage 60 est en position active, la tranche inférieure 70 de l'embout 20 se superposant partiellement à la nervure 68 de l'organe de blocage.On the figure 10 , we see that the locking member 60 is in the active position, the lower edge 70 of the nozzle 20 partially overlapping the rib 68 of the locking member.

Sur la figure 11, on voit que l'organe de blocage 60 est passé dans la position inactive, la tranche inférieure 70 de l'embout 20 ne se superposant plus avec la nervure 68 et l'embout 20 pouvant s'enfoncer davantage.On the figure 11 , we see that the locking member 60 has moved into the inactive position, the lower edge 70 of the tip 20 no longer overlapping with the rib 68 and the tip 20 can be further sinking.

Dans cette configuration inactive, la tige de distribution 33 se situe sensiblement en regard de la portion 64 du bord de l'encoche 62.In this inactive configuration, the distribution rod 33 is located substantially opposite the portion 64 of the edge of the notch 62.

Dans la figure 10, la tige de distribution 33 se situe sensiblement contre la portion 63 du bord de l'encoche 62.In the figure 10 , the dispensing rod 33 is located substantially against the portion 63 of the edge of the notch 62.

Sur les figures 12 et 13, on voit que lorsque l'utilisateur appuie sur la surface de commande 15, le levier 14 peut basculer vers le bas tandis que les ponts de matière 58 permettent à l'embout 20 de rester sensiblement co-axial à la tige de distribution.On the Figures 12 and 13 it can be seen that when the user presses on the control surface 15, the lever 14 can swing downwards while the material bridges 58 allow the nozzle 20 to remain substantially coaxial with the dispensing rod.

Dans la variante de la figure 14, l'organe 60 comporte un ajour 162 qui remplace l'encoche 62 et qui présente un contour formé.In the variant of the figure 14 , the member 60 comprises an opening 162 which replaces the notch 62 and which has a contour formed.

La tige de distribution 33 est engagée dans cet ajour 162 et peut coopérer avec les portions de bord 63 et 64.The dispensing rod 33 is engaged in this opening 162 and can cooperate with the edge portions 63 and 64.

Dans l'exemple représenté à la figure 15, l'organe de blocage 60 comporte un ajour 162 dont le contour, selon une section transversale prise perpendiculairement à l'axe longitudinal de la tige de distribution 33, est fermé et en forme de huit. L'ajour 162 comporte deux portions de contour sensiblement circulaire autour d'axes respectifs distants d'un écart référencé E63 sur la figure 15. Plus les arêtes 163, à la jonction des deux portions de contour circulaire, sont rapprochées l'une de l'autre, plus le franchissement par la tige de distribution de l'intervalle formé entre ces arêtes 163 est dur. Le rayon R6 de chacune des deux portions de contour circulaire correspond par exemple sensiblement au rayon extérieur de la tige de distribution 33. Les centres des portions de contour circulaire se situent sur une trajectoire circulaire à la même distance de l'axe K de l'articulation 61 de l'organe de blocage 60 par rapport à la partie de base 13.In the example shown in figure 15 , the locking member 60 comprises an aperture 162 whose contour, in a cross section taken perpendicularly to the longitudinal axis of the dispensing rod 33, is closed and shaped eight. The aperture 162 has two portions of substantially circular contour around respective axes distant from a distance referenced E63 on the figure 15 . The more the edges 163, at the junction of the two circular contour portions, are brought closer to each other, the more the crossing by the distribution rod of the gap formed between these edges 163 is hard. The radius R6 of each of the two circular contour portions corresponds for example substantially to the outer radius of the distribution rod 33. The centers of the circular contour portions are located on a circular path at the same distance from the axis K of the articulation 61 of the locking member 60 with respect to the base portion 13.

Des marques visuelles comprenant par exemple les inscriptions « ON » ou « OFF » ou des flèches sont par exemple inscrites à côté des montants d'appui 73 et 74, comme illustré.Visual marks including, for example, the "ON" or "OFF" markings or arrows are, for example, written beside the support posts 73 and 74, as illustrated.

Comme représenté à la figure 18, le montant 43 de la partie de base 13, sur lequel se raccorde la charnière 35, peut avoir une hauteur H43 supérieure à celle du montant de l'exemple de réalisation de la figure 2. La hauteur H43 est mesurée entre l'extrémité inférieure de la partie de base 13 et l'extrémité supérieure du montant 43. En particulier, la charnière 35 peut se situer à une altitude supérieure à celle des montants 73 et 74 et à celle de l'extrémité inférieure de l'embout 20 quand le levier 14 est au repos, prêt à être actionné par l'utilisateur pour distribuer le produit. La hauteur H43 est par exemple supérieure ou égale à 20 mm, étant par exemple comprise entre 20 et 30 mm, par exemple entre 24 et 28 mm, par exemple de l'ordre de 27 mm.As represented in figure 18 , the amount 43 of the base portion 13, to which the hinge 35 is connected, may have a height H43 greater than that of the amount of the embodiment of the figure 2 . The height H43 is measured between the lower end of the base portion 13 and the upper end of the upright 43. In particular, the hinge 35 may be at an altitude greater than that of the uprights 73 and 74 and that of the upright. lower end of the tip 20 when the lever 14 is at rest, ready to be operated by the user to distribute the product. The height H43 is for example greater than or equal to 20 mm, being for example between 20 and 30 mm, for example between 24 and 28 mm, for example of the order of 27 mm.

On voit sur la figure 16 notamment que l'extrémité libre 17a du conduit 17 peut se situer dans un plan S perpendiculaire à la direction E, en avant de la surface de commande 15.We see on the figure 16 in particular that the free end 17a of the duct 17 can be located in a plane S perpendicular to the direction E, in front of the control surface 15.

Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits.Of course, the invention is not limited to the examples which have just been described.

En particulier, on peut munir la tête de distribution d'un organe de rappel élastique propre à rappeler le levier 14 dans sa position initiale après chaque actionnement, ce qui peut être utile lorsque la valve du récipient ne dispose pas de la force nécessaire.In particular, it can provide the dispensing head with an elastic return member adapted to recall the lever 14 in its initial position after each actuation, which can be useful when the valve of the container does not have the necessary force.

Dans une variante, le levier vient appuyer par sa face inférieure sur le conduit de distribution.In a variant, the lever is supported by its lower face on the distribution duct.

On peut équiper d'une tête de distribution selon l'invention un récipient muni d'une pompe et non plus un bidon aérosol.It is possible to equip a dispensing head according to the invention with a container provided with a pump and no longer with an aerosol can.

L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
