Description

La présente invention concerne un dispositif de conditionnement et de distribution d'un produit sous pression, et en particulier un dispositif qui permet de vider automatiquement son contenu.The present invention relates to a device for packaging and dispensing a product under pressure, and in particular a device that allows its contents to be emptied automatically.

Les dispositifs de distribution de produit sous pression de type aérosol comportent généralement un récipient rigide, de préférence en métal ou en matière plastique, dans lequel est conditionné le produit à distribuer ainsi qu'un gaz propulseur permettant de propulser le produit. Ils comportent également une valve de distribution montée généralement sur une coupelle, la valve étant surmontée d'un diffuseur permettant de l'actionner pour faire sortir le produit. Les diffuseurs permettent d'actionner la valve mais aussi de canaliser le produit depuis la tige d'actionnement de la valve jusqu'à un orifice de diffusion.Aerosol-type pressurized product dispensing devices generally comprise a rigid container, preferably made of metal or plastic, in which the product to be dispensed is conditioned, as well as a propellant for propelling the product. They also include a dispensing valve mounted generally on a cup, the valve being surmounted by a diffuser to actuate it to bring out the product. The diffusers make it possible to actuate the valve but also to channel the product from the actuating rod of the valve to a diffusion orifice.

Avant de détruire ou de recycler de tels dispositifs, il est préférable de vider complètement le contenu, et en particulier le gaz propulseur. Toutefois, il peut être laborieux de maintenir manuellement le bouton-poussoir jusqu'à ce que le récipient soit vide.Before destroying or recycling such devices, it is best to completely empty the contents, especially the propellant. However, it can be laborious to manually hold the push button until the container is empty.

C'est pourquoi, il a déjà été proposé des dispositifs qui permettent de vider le contenu des récipients sans avoir besoin de maintenir une pression manuelle sur le bouton-poussoir.Therefore, it has already been proposed devices that allow to empty the contents of the containers without the need to maintain manual pressure on the push button.

Avec certains types de diffuseurs, il est relativement simple de prévoir des systèmes de vidange qui viennent en appui sur le bouton-poussoir ou sur la tige de valve, après avoir ôté au préalable le bouton-poussoir, et qui se fixent sur le récipient ou la coupelle portant la valve de façon à maintenir le bouton poussoir et/ou la valve enfoncé(e) ou basculé(e). C'est le cas notamment des diffuseurs qui se fixent directement sur la tige de valve et qui laissent la coupelle ou le bord supérieur du récipient accessible pour former une zone d'accroche.With certain types of diffusers, it is relatively simple to provide emptying systems which come to bear on the pushbutton or on the valve stem, after having previously removed the pushbutton, and which are fixed on the container or the cup carrying the valve so as to hold the push button and / or the valve depressed (e) or tilted (e). This is particularly the case of diffusers that attach themselves directly to the valve stem and leave the cup or the top edge of the container accessible to form a catchment area.

Le document GB 974 278 décrit par exemple un diffuseur emmanché sur une tige de valve. Un organe de vidange formé par une pièce rapportée se fixe sur la partie enroulée de la coupelle et vient, soit basculer la tige de valve, soit appuyer sur le diffuseur. Cette pièce n'a pas une ergonomie qui lui permet d'être attachée facilement au diffuseur ou au récipient lors de sa commercialisation.The document GB 974,278 describes for example a diffuser fitted on a valve stem. An emptying member formed by an insert attaches to the wound portion of the cup and comes to either tilt the valve stem or press the diffuser. This piece does not have an ergonomics that allows it to be easily attached to the diffuser or the container during its marketing.

Le document JP2004 168356 décrit aussi un diffuseur emmanché sur une tige de valve qui est protégé par un capot venant se fixer sur la coupelle portant la valve. La paroi supérieure du capot comporte une partie mobile pouvant basculer de manière à venir en appui sur le diffuseur pour le maintenir enfoncé afin de vider le contenu du récipient.The document JP2004 168356 also discloses a diffuser fitted on a valve stem which is protected by a cap which is fixed on the cup carrying the valve. The upper wall of the cover comprises a movable part that can tilt so as to bear against the diffuser to hold it down to empty the contents of the container.

Le document US 3,137,414 décrit un diffuseur comportant une partie fixée à la coupelle, sur la paroi intérieure de celle-ci, et une surface d'actionnement, mobile par rapport à la partie fixe pour basculer la tige de valve. Là encore, un capot de protection vient se fixer sur la coupelle portant la valve, à l'extérieur de celle-ci, et comporte une paroi supérieure pouvant basculer de manière à venir en appui sur la surface d'actionnement afin de vider le contenu du récipient. Le bord libre de la paroi ainsi basculée vient appuyer sur la surface d'actionnement afin de faire sortir le produit par un orifice de distribution formé sur la surface d'actionnement.The document US 3,137,414 discloses a diffuser having a portion attached to the cup, on the inner wall thereof, and an actuating surface movable relative to the fixed portion for tilting the valve stem. Again, a protective cover is attached to the cup carrying the valve, outside thereof, and has a top wall that can tilt so as to bear against the actuating surface to empty the contents. of the container. The free edge of the wall thus tilted presses on the actuating surface to release the product through a dispensing orifice formed on the actuating surface.

Dans ces deux derniers documents, c'est le capot de protection qui sert aussi d'organe de vidange. Le capot étant séparé du diffuseur à chaque fois que l'utilisateur souhaite distribuer du produit, en utilisation normale, l'utilisateur risque de perdre le capot, et donc l'organe de vidange, avant la fin d'utilisation normale du dispositif de distribution, sans avoir pu utiliser l'organe de vidange pour vidanger le récipient.In these last two documents, it is the protective cover which also serves as emptying member. The cover being separated from the diffuser each time the user wishes to distribute the product, in normal use, the user may lose the cover, and therefore the emptying member, before the end of normal use of the dispensing device , without having been able to use the emptying device to empty the container.

D'autre part, certains diffuseurs appelés microdiffuseurs, comprennent une partie qui vient se fixer sur le récipient en masquant l'accès à la coupelle, et une surface d'actionnement mobile par rapport à la partie fixe, sur laquelle l'utilisateur peut appuyer pour actionner la valve. La partie du diffuseur fixée au récipient forme une paroi latérale qui prolonge la paroi latérale du récipient, son diamètre externe étant sensiblement égal à celui du récipient de sorte qu'ils ont également une fonction de capot de protection de la valve et de la coupelle. Le produit est distribué par un orifice de diffusion formé dans la paroi latérale du diffuseur. Avec ce type de diffuseurs, ni la coupelle, ni le bord supérieur du récipient n'est accessible pour former une zone d'accroche car le diffuseur les entoure entièrement.On the other hand, some broadcasters called microdiffusers, include a portion that is fixed on the container by hiding the access to the cup, and an actuating surface movable relative to the fixed part, on which the user can press to operate the valve. The part of the broadcaster container forms a side wall which extends the side wall of the container, its outer diameter being substantially equal to that of the container so that they also have a protective cap function of the valve and the cup. The product is distributed through a diffusion orifice formed in the side wall of the diffuser. With this type of diffuser, neither the cup nor the upper edge of the container is accessible to form a hooking zone because the diffuser surrounds them entirely.

Le document W02006/070888 décrit différents types de diffuseurs sur lesquels viennent se placer des pièces prévues pour les actionner de façon automatique. Les pièces prévues à cet effet sont destinées à pouvoir être utilisées sur différents types de diffuseurs, notamment des diffuseurs montés directement sur des tiges de valves et des microdiffuseurs. Ces pièces ont donc des formes leur permettant de s'adapter à plusieurs diffuseurs, ce qui les oblige à être relativement encombrantes.The document W02006 / 070888 describes different types of diffusers on which are placed parts intended to operate automatically. The parts provided for this purpose are intended to be used on different types of diffusers, including diffusers mounted directly on valve stems and microdiffusers. These parts have shapes that allow them to adapt to multiple diffusers, which forces them to be relatively bulky.

C'est pourquoi il existe un besoin pour réaliser un dispositif de conditionnement et de distribution d'un produit sous pression comportant un diffuseur de type microdiffuseur équipé d'un élément pouvant actionner la valve automatiquement.Therefore, there is a need for a device for packaging and dispensing a pressurized product comprising a diffuser type microdiffuseur equipped with an element that can actuate the valve automatically.

Il existe aussi un besoin de réaliser un tel dispositif qui soit simple à réaliser et pratique à utiliser, et notamment qui limite les risques de perte de l'élément prévu pour actionner la valve automatiquement.There is also a need to make such a device that is simple to implement and practical to use, and in particular that limits the risk of loss of the element intended to actuate the valve automatically.

L'invention a ainsi pour objet, selon l'un de ses aspects, un dispositif de conditionnement et de distribution d'un produit sous pression comportant au moins un récipient contenant le produit, le récipient étant surmonté d'une valve et d'une tête de distribution pour actionner la valve et permettre la sortie du produit via au moins un orifice de distribution, la tête de distribution comportant une première portion fixe, selon l'axe longitudinal du récipient, par rapport au récipient et une seconde portion mobile par rapport à la première autour d'un axe, pour actionner la valve, le dispositif comportant en outre un organe de vidange apte à prendre une position dans laquelle la valve est maintenue en position d'actionnement, l'organe de vidange, dans cette position de vidange, comportant une première partie venant en appui sur la seconde portion mobile de la tête de distribution, et une seconde partie venant en butée avec la première portion de la tête de distribution de manière à s'opposer au retour de la seconde portion mobile de la tête de distribution, l'organe de vidange étant, au moins avant une première utilisation, retenu sur le récipient ou la tête de distribution.The invention thus has, according to one of its aspects, a device for packaging and dispensing a product under pressure comprising at least one container containing the product, the container being surmounted by a valve and a dispensing head for actuating the valve and allowing the outlet of the product via at least one dispensing orifice, the dispensing head having a first fixed portion, along the longitudinal axis of the container, relative to the container and a second movable portion relative to at the first axis, to actuate the valve, the device further comprising a drain member adapted to take a position in which the valve is maintained in actuating position, the emptying member, in this emptying position, having a first portion bearing on the second movable portion of the dispensing head, and a second portion abutting with the first portion of the head of the dispensing head; distribution so as to oppose the return of the second movable portion of the dispensing head, the emptying member being, at least before a first use, retained on the container or the dispensing head.

L'organe de vidange peut ainsi être maintenu en position de vidange dans laquelle il maintient la valve actionnée en coopérant seulement avec la tête de distribution ce qui permet de l'utiliser avec des têtes de distribution du type microdiffuseur.The emptying member can thus be held in the emptying position in which it maintains the valve actuated cooperating only with the dispensing head which allows it to be used with distribution heads of the microdiffuseur type.

L'organe de vidange peut venir en appui sur la seconde portion mobile de la tête de distribution selon une direction distincte de la direction de sortie du produit par l'orifice de distribution.The emptying member may bear on the second movable portion of the dispensing head in a direction distinct from the outlet direction of the product by the dispensing orifice.

L'organe de vidange peut venir en appui sur une zone de la seconde portion mobile la plus éloignée de l'orifice de distribution.The emptying member may bear on an area of the second movable portion farthest from the dispensing orifice.

En particulier, la première partie de l'organe de vidange venant en appui sur la seconde portion mobile de la tête de distribution est introduite dans cette position à l'arrière de l'orifice de distribution. Autrement dit, la première portion de l'organe de vidange ne passe jamais du côté du plan tangent à l'orifice du côté duquel sort le produit, elle ne coupe pas ce plan.In particular, the first part of the emptying member bearing on the second movable portion of the dispensing head is introduced into this position at the rear of the dispensing orifice. In other words, the first portion of the drain member never passes on the side of the tangent plane to the orifice on which the product comes out, it does not cut this plane.

On limite ainsi les risques que, lors de la mise en place de l'organe de vidange, l'utilisateur reçoive des projections de produit sur les mains.This limits the risks that, when setting up the emptying member, the user receives product projections on the hands.

La première portion de la tête de distribution peut être fixée sur le récipient ou, en variante, sur une coupelle portant la valve.The first portion of the dispensing head may be attached to the container or, alternatively, to a cup carrying the valve.

Le dispositif de conditionnement peut comporter une coupelle portant la valve, notamment sertie sur le récipient, la tête de distribution entourant la coupelle de manière telle que la coupelle n'est pas accessible depuis l'extérieur.The packaging device may comprise a cup carrying the valve, in particular crimped on the container, the dispensing head surrounding the cup of such that the cup is not accessible from the outside.

L'organe de vidange peut être un élément distinct d'un capot de protection.The drain member may be a separate element of a protective cover.

L'organe de vidange peut comporter une paroi délimitée par un bord supérieur et un bord inférieur ainsi que par deux bords latéraux, la paroi étant incurvée entre les deux bords latéraux et sensiblement droite entre le bord supérieur et le bord inférieur. L'organe de vidange présente une forme simple, facile à réaliser et à manipuler. En outre, sa forme incurvée lui permet de facilement se positionner sur un diffuseur classique de section transversale circulaire lors de son utilisation. Elle lui permet aussi de se positionner sur un récipient de section transversale circulaire lors de son conditionnement sans former de protubérances trop importantes qui pourraient augmenter de façon trop importante l'encombrement du dispositif.The emptying member may comprise a wall delimited by an upper edge and a lower edge as well as by two lateral edges, the wall being curved between the two lateral edges and substantially straight between the upper edge and the lower edge. The emptying member has a simple shape, easy to make and handle. In addition, its curved shape allows it to easily position itself on a conventional diffuser of circular cross section during use. It also allows it to position itself on a container of circular cross section during its packaging without forming too large protuberances that could significantly increase the size of the device.

Le bord inférieur de l'organe de vidange peut venir en appui sur la seconde portion mobile de la tête de distribution.The lower edge of the drain member may bear against the second movable portion of the dispensing head.

L'organe de vidange peut en outre comporter des ergots formés à l'extrémité de deux tiges, le bord supérieur des ergots venant en butée avec la première portion de la tête de distribution. Les ergots peuvent ainsi facilement être placés en butée sous une paroi grâce à la souplesse des tiges qui les portent.The emptying member may further comprise lugs formed at the end of two rods, the upper edge of the lugs abutting with the first portion of the dispensing head. The lugs can easily be placed in abutment under a wall thanks to the flexibility of the rods that carry them.

En variante, l'organe de vidange peut comporter, à proximité de son bord inférieur, un rebord transversal à la paroi, le rebord venant en butée avec la première portion de la tête de distribution.Alternatively, the emptying member may comprise, near its lower edge, a flange transverse to the wall, the flange abutting with the first portion of the dispensing head.

L'organe de vidange peut être, avant une première utilisation, retenu sur le récipient ou la tête de distribution de façon à équiper chaque dispositif d'un tel organe de vidange. L'organe de vidange peut en outre être retenu sur le récipient ou la tête de distribution lors de la distribution du produit en réponse à une pression manuelle d'un utilisateur sur la seconde portion mobile, sans utiliser l'organe de vidange, c'est-à-dire lors de l'utilisation normale du dispositif. A cet effet, l'organe de vidange peut être retenu sur le récipient ou la tête de distribution par un film de protection entourant le dispositif et plaquant l'organe de vidange sur le récipient ou la tête de distribution. Alternativement, l'organe de vidange peut être retenu sur le récipient ou la tête de distribution par deux bras enlaçant le récipient ou la tête de distribution, ou encore par un anneau fixé par encliquetage ou serrage sur le récipient et/ou la tête de distribution. En variante encore, l'organe de vidange peut être réalisé d'un seul tenant avec une partie de la tête de distribution à laquelle il est relié par au moins un pont de matière sécable. L'organe de vidange peut alors, après avoir été désolidarisé de la tête de distribution, être logé dans une fente ménagée dans la première portion fixe de la tête de distribution.The emptying member may be, before a first use, retained on the container or the dispensing head so as to equip each device with such a drain member. The emptying member may also be retained on the container or the dispensing head during dispensing of the product in response to manual pressure from a user on the second movable portion, without using the drain member, that is, during normal use of the device. For this purpose, the emptying member may be retained on the container or the head of distribution by a protective film surrounding the device and plating the drain member on the container or the dispensing head. Alternatively, the drain member may be retained on the container or the dispensing head by two arms embracing the container or the dispensing head, or by a ring fixed by snapping or clamping on the container and / or the dispensing head . In another variant, the emptying member may be made in one piece with a portion of the dispensing head to which it is connected by at least one breakable material bridge. The emptying member can then, after being detached from the dispensing head, be housed in a slot in the first fixed portion of the dispensing head.

On peut donc distribuer du produit de façon classique sans enlever l'organe de vidange du dispositif, si bien qu'on limite les risques de perdre cet organe de vidange avant de l'utiliser.It is therefore possible to distribute the product in a conventional manner without removing the drain member of the device, so that the risk of losing this drain member before using it is limited.

L'organe de vidange peut comporter un cache destiné à être positionné en regard de l'orifice de distribution du produit lorsque l'organe de vidange est en position de vidange de manière à contenir la diffusion du spray dans l'atmosphère lors de la vidange.The emptying member may comprise a cover intended to be positioned facing the dispensing orifice of the product when the discharge member is in the emptying position so as to contain the diffusion of the spray into the atmosphere during the emptying. .

Le produit contenu dans le récipient peut être un produit cosmétique.The product contained in the container may be a cosmetic product.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un dispositif de conditionnement et de distribution d'un produit sous pression comportant au moins un récipient contenant le produit, le récipient étant surmonté d'une valve et d'une tête de distribution pour actionner la valve et permettre la sortie du produit via au moins un orifice de distribution, la tête de distribution comportant une première portion fixe, selon l'axe longitudinal du récipient, par rapport au récipient, et une seconde portion, mobile par rapport à la première, autour d'un axe pour actionner la valve, le dispositif comportant en outre un organe de vidange apte à prendre une position dans laquelle la valve est maintenue en position d'actionnement, l'organe de vidange, dans cette position de vidange, venant en appui sur la seconde portion mobile de la tête de distribution selon une direction distincte de la direction de sortie du produit par l'orifice de distribution la portion de l'organe de vidange venant en appui sur la seconde portion mobile étant introduite dans cette position à l'arrière de l'orifice de distribution. L'utilisateur ne risque donc pas de recevoir du produit sur ses doigts lors de la mise en place de l'organe de vidange sur la tête de distribution.The invention also relates, independently or in combination with the foregoing, to a device for packaging and dispensing a product under pressure comprising at least one container containing the product, the container being surmounted by a valve and a dispensing head for actuating the valve and allowing the product to exit via at least one dispensing orifice, the dispensing head having a first fixed portion, along the longitudinal axis of the container, with respect to the container, and a second portion, movable relative to the first, about an axis for actuating the valve, the device further comprising a drain member adapted to take a position in which the valve is held in the actuating position, the drain member, in this emptying position, bearing on the second movable portion of the dispensing head in a direction distinct from the product outlet direction through the dispensing orifice the portion of the drain member bearing on the second movable portion being introduced in this position at the rear of the dispensing orifice. The user is therefore unlikely to receive product on his fingers during the introduction of the emptying member on the dispensing head.

On a représenté sur les figures 1 et 5 un dispositif de distribution 10 comportant un récipient 20 surmonté d'une tête de distribution 30.FIGS. 1 and 5 show a dispensing device 10 comprising a container 20 surmounted by a dispensing head 30.

Comme on le voit à la figure 5, le récipient 20 comporte par exemple un bidon pressurisé muni d'une valve maintenue sur le bidon par une coupelle 21 sertie sur la partie supérieure du bidon et fermant la partie supérieure du bidon, cette valve ayant une tige de valve 22, creuse. La valve peut être de tout type connu, l'actionnement s'effectuant par exemple par un enfoncement de la tige.As can be seen in FIG. 5, the container 20 comprises, for example, a pressurized container provided with a valve held on the can by a cup 21 crimped on the upper part of the can and closing the upper part of the can, this valve having a valve stem 22, hollow. The valve can be of any known type, the actuation being effected for example by a depression of the rod.

Le récipient 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 et être délivré avec le produit.The container may contain a product to be sprayed, for example a cosmetic product, and a propellant, which may or may not be stored in a liquefied form in the container and be delivered with the product.

La tête de distribution est du type microdiffuseur, c'est-à-dire qu'elle intègre la fonction de diffuseur et de capot. Elle comporte une première portion 40 fixée sur le bidon 20, et une seconde portion 50, mobile par rapport à la première partie autour d'un axe de basculement de manière à actionner la valve. Le diamètre extérieur de la tête de distribution est sensiblement égal au diamètre du bidon 20 qui est lui-même cylindrique de révolution.The dispensing head is of the microdiffusor type, that is to say that it integrates the function of diffuser and hood. It comprises a first portion 40 fixed on the can 20, and a second portion 50, movable relative to the first portion about a tilting axis so as to actuate the valve. The outer diameter of the dispensing head is substantially equal to the diameter of the can 20 which is itself cylindrical of revolution.

La première portion 40 comporte essentiellement une jupe cylindrique 41, de section transversale circulaire, constituant la paroi latérale de la tête de distribution, et se raccordant en partie supérieure à une paroi transversale 42.The first portion 40 essentially comprises a cylindrical skirt 41, of circular cross-section, constituting the lateral wall of the dispensing head, and connected in the upper part to a transverse wall 42.

La jupe cylindrique 41 est munie en partie inférieure d'un bourrelet 43 permettant de la fixer par encliquetage dans une gorge annulaire 23 présente dans une partie supérieure du bidon de diamètre sensiblement rétréci.The cylindrical skirt 41 is provided in the lower part with a bead 43 for fixing it by snapping into an annular groove 23 present in an upper part of the drum of substantially narrowed diameter.

Une ouverture 44 est prévue dans la paroi transversale 42 pour permettre d'accéder à la seconde portion mobile 50 actionnant la valve. L'ouverture 44 est de forme allongée et est délimitée par deux bords droits 44a s'écartant l'un de l'autre jusqu'à, d'un côté, la périphérie de la paroi transversale 42 et se prolonge sur une partie de la hauteur de la jupe cylindrique 41. Les deux bords 44a se raccordent de l'autre côté, à distance de la périphérie de la paroi transversale.An opening 44 is provided in the transverse wall 42 to allow access to the second movable portion 50 actuating the valve. The opening 44 is of elongate shape and is delimited by two straight edges 44a deviating from one another to, on one side, the periphery of the transverse wall 42 and extends over part of the height of the cylindrical skirt 41. The two edges 44a are connected on the other side, away from the periphery of the transverse wall.

Deux parois intérieures 45 s'étendent depuis chaque bord 44a, perpendiculairement à la paroi transversale 42 et donc parallèlement à la jupe 41. Elles se terminent par un bord libre 45a.Two inner walls 45 extend from each edge 44a, perpendicular to the transverse wall 42 and therefore parallel to the skirt 41. They terminate in a free edge 45a.

Un rebord 46 rentrant vers l'intérieur de la jupe 41 est également prévu au niveau du bord supérieur de la jupe 41 qui délimite l'ouverture 44.A flange 46 entering the interior of the skirt 41 is also provided at the upper edge of the skirt 41 which defines the opening 44.

La jupe cylindrique 41 est également traversée par une ouverture frontale 47, opposée à l'ouverture 44, en regard de laquelle débouche un orifice de distribution 55, au travers duquel peut s'effectuer la distribution du produit, lorsque l'on appuie sur la partie mobile 50.The cylindrical skirt 41 is also traversed by a front opening 47, opposite to the opening 44, facing which opens a dispensing orifice 55, through which the dispensing of the product can take place, when pressing the moving part 50.

La seconde portion mobile 50 comporte une paroi supérieure, destinée à servir d'appui à un doigt de l'utilisateur de manière à constituer une surface d'actionnement 51. La surface d'actionnement 51 comporte donc une composante perpendiculaire à la tige d'actionnement de la valve. La surface d'actionnement se prolonge verticalement vers le bas pour obturer l'ouverture 44 qui se prolonge dans la jupe 41 pour se terminer par un rebord 52 transversal.The second movable portion 50 comprises an upper wall intended to serve as a support for a user's finger so as to constitute an actuating surface 51. The actuating surface 51 therefore comprises a component perpendicular to the stem of the user. actuation of the valve. The actuating surface extends vertically downwards to seal the opening 44 which extends into the skirt 41 to end with a transverse rim 52.

La surface d'actionnement 51 se raccorde sur sa surface interne à un conduit 53 qui délimite un canal 54 prévu pour acheminer le produit provenant de la tige de valve 22 jusqu'à l'orifice de distribution 55.The actuating surface 51 is connected on its inner surface to a conduit 53 which delimits a channel 54 provided for conveying the product from the valve stem 22 to the dispensing orifice 55.

En particulier, le conduit 53 comporte une jupe cylindrique 56 de révolution qui s'étend sensiblement dans l'axe de la tige de valve, la jupe cylindrique 56 se raccordant dans sa partie supérieure à la surface d'actionnement 51. La jupe cylindrique 56 définit, dans sa partie inférieure, un logement épaulé 57 dans lequel peut s'engager de manière sensiblement étanche la partie supérieure de la tige de valve, comme on peut le voir sur la figure 5. On voit également sur cette figure que la tige de valve 22 vient en butée par son extrémité supérieure 22a contre l'épaulement 57 du logement. La jupe 56 délimite une première portion du canal d'acheminement 54 du produit.In particular, the conduit 53 comprises a cylindrical skirt 56 of revolution which extends substantially in the axis of the valve stem, the cylindrical skirt 56 being connected in its upper part to the actuating surface 51. The cylindrical skirt 56 defines, in its lower part, a stepped housing 57 in which the upper part of the valve stem can be substantially sealingly engaged, as can be seen in FIG. 5. It can also be seen in this figure that the stem of valve 22 abuts by its upper end 22a against the shoulder 57 of the housing. The skirt 56 defines a first portion of the delivery channel 54 of the product.

Le canal d'acheminement 54 se prolonge par une seconde portion, transversale à la première, qui est délimitée par un tube 58. Le tube 58 est de forme allongée selon un axe perpendiculaire à l'axe principal de la tige de valve, et s'étend depuis la jupe cylindrique 56 jusqu'à une extrémité débouchant par l'orifice de distribution 55 délimité par une buse rapportée 80, par exemple une buse conventionnelle à canaux tourbillonnaires.The delivery channel 54 is extended by a second portion, transverse to the first, which is delimited by a tube 58. The tube 58 is of elongate shape along an axis perpendicular to the main axis of the valve stem, and extends from the cylindrical skirt 56 to an end opening through the dispensing orifice 55 defined by an attached nozzle 80, for example a conventional swirling channel nozzle.

La seconde portion mobile 50 de la tête de distribution est articulée sur la première portion 40 de la tête de distribution autour d'un axe, par exemple par deux arbres, non illustrés, logés dans deux orifices dans lesquels les arbres peuvent tourner. Les orifices sont par exemple formés dans les parois intérieures 45 de la première portion fixe 40, du côté de l'orifice de distribution.The second movable portion 50 of the dispensing head is articulated on the first portion 40 of the dispensing head about an axis, for example by two shafts, not shown, housed in two orifices in which the shafts can rotate. The orifices are for example formed in the inner walls 45 of the first fixed portion 40, on the side of the dispensing orifice.

Le dispositif de conditionnement et de distribution 10 illustré à la figure 1 comporte également un organe de vidange 60, retenu sur le récipient par un film de protection 70 selon l'exemple illustré. Le film de protection 70 est un manchon rétractable qui vient se plaquer sur le récipient et la tête de distribution pour protéger le dispositif, et qui maintient également par serrage l'organe de vidange 60 sur le récipient.The packaging and dispensing device 10 illustrated in FIG. 1 also comprises a drain member 60 retained on the container by a protective film 70 according to the illustrated example. The protective film 70 is a retractable sleeve which is pressed against the container and the dispensing head to protect the device, and which also clamps the drain member 60 on the container.

L'organe de vidange 60, illustré isolément à la figure 3, est constitué par une paroi 61 comportant un bord supérieur 62 et un bord inférieur 63 ainsi que deux bords latéraux 64. La paroi 61 est sensiblement droite entre ses bords inférieur et supérieur alors qu'elle est incurvée entre ses deux bords latéraux 64 de manière à épouser la courbe de la jupe cylindrique 41. Deux fentes verticales 66 sont prévues de manière à former deux tiges 67 sur les bords latéraux de la paroi 61. Un ergot 65 est formé à l'extrémité de chacune des tiges dans le prolongement latéral de la paroi 61 de manière à former un hameçon. Le bord supérieur 65a de chaque ergot est prévu pour s'accrocher sur la première portion fixe 40 de la tête de distribution. Au dessus des fentes, un décrochement 68 peut en outre être prévu sur chaque bord latéral 64 de la paroi 61.The emptying member 60, illustrated in isolation in FIG. 3, is constituted by a wall 61 comprising an upper edge 62 and a lower edge 63 as well as two lateral edges 64. The wall 61 is substantially straight between its lower and upper edges then that it is curved between its two lateral edges 64 so as to match the curve of the cylindrical skirt 41. Two vertical slots 66 are provided so as to form two rods 67 on the lateral edges of the wall 61. A lug 65 is formed at the end of each of the rods in the lateral extension of the wall 61 so as to form a hook. The upper edge 65a of each lug is provided to hook on the first fixed portion 40 of the dispensing head. Above the slots, a recess 68 may further be provided on each lateral edge 64 of the wall 61.

Comme on le voit à la figure 1, le dispositif de conditionnement et de distribution est commercialisé avec l'organe de vidange 60 maintenu sur le récipient par le film de protection 70 qui entoure le récipient, sans masquer l'orifice de pulvérisation 55.As seen in FIG. 1, the packaging and dispensing device is marketed with the emptying member 60 held on the container by the protective film 70 which surrounds the container, without concealing the spray orifice 55.

L'utilisateur peut distribuer du produit de façon classique, à plusieurs reprises, en appuyant sur la surface d'actionnement 51 avec son doigt pour actionner la valve et faire sortir le produit alors que l'organe de vidange 60 est toujours maintenu sur le récipient. L'organe de vidange 60 ne risque pas d'être égaré pendant toute la phase d'utilisation normale du dispositif.The user can distribute the product in a conventional manner, repeatedly, by pressing on the actuating surface 51 with his finger to actuate the valve and release the product while the drain member 60 is still held on the container . The emptying member 60 will not be lost during the normal use phase of the device.

Lorsqu'il n'y a pratiquement plus de produit et que l'utilisateur souhaite jeter le dispositif, il peut vider le contenu du gaz propulseur restant dans le récipient, et le cas échéant le reste du produit, en utilisant l'organe de vidange 60. L'utilisateur retire alors le film de protection 70 pour pouvoir prendre l'organe de vidange 60. Il place l'organe de vidange 60 au travers de l'ouverture 44 formée dans la paroi transversale 42, à l'arrière de la surface d'actionnement 51 c'est-à-dire à proximité de la jupe 41. L'extrémité inférieure 63 de l'organe de vidange vient en appui sur le rebord 52 prolongeant la surface d'actionnement 51 de la portion mobile 50 de la tête de distribution de manière à la déplacer et à actionner la valve. Les deux décrochements 68 de l'organe de vidange viennent alors en butée contre la paroi transversale 42 de manière à limiter l'enfoncement de l'organe de vidange dans la tête de distribution. On peut bien sûr s'affranchir de cette butée. Dans cette position, les ergots 65 se placent sous chaque paroi intérieure 45 de la portion fixe 40 de la tête de distribution. Les bords supérieurs 65a des ergots 65 viennent alors en butée contre le bord inférieur 45a des parois intérieures 45 de façon à s'opposer au retour de la portion mobile 50 de la tête de distribution. La portion mobile 50 reste donc dans sa position enfoncée dans laquelle la valve est actionnée de sorte que tout le produit et le gaz propulseur encore présents dans le récipient puissent être vidés. En outre, l'extrémité inférieure 63 de l'organe de vidange est introduite dans la position de vidange à l'arrière de l'orifice de distribution. L'extrémité 63 de l'organe de vidange ne passe jamais du côté du plan P tangent à l'orifice du côté duquel sort le produit, elle ne coupe pas ce plan.When there is practically no product and the user wants to discard the device, it can empty the contents of the propellant remaining in the container, and if necessary the rest of the product, using the drain member 60. The user then removes the protective film 70 to be able to take the emptying member 60. He places the emptying member 60 through the opening 44 formed in the transverse wall 42 at the rear of the actuating surface 51 that is to say near the skirt 41. The lower end 63 of the drain member abuts on the flange 52 extending the actuating surface 51 of the movable portion 50 of the dispensing head so as to move and actuate the valve. The two recesses 68 of the emptying member then abut against the transverse wall 42 so as to limit the depression of the drain member in the dispensing head. We can of course get rid of this stop. In this position, the lugs 65 are placed under each inner wall 45 of the fixed portion 40 of the dispensing head. The upper edges 65a of the lugs 65 then abut against the lower edge 45a of the inner walls 45 so as to oppose the return of the movable portion 50 of the dispensing head. The movable portion 50 remains in its depressed position in which the valve is actuated so that all the product and the propellant gas still present in the container can be emptied. In addition, the lower end 63 of the drain member is introduced into the drain position at the rear of the dispensing orifice. The end 63 of the drain member never passes on the side of the plane P tangent to the orifice on which the product comes out, it does not cut this plane.

L'utilisateur ne risque pas de recevoir de produit sur ses doigts lors de la mise en place de l'organe de vidange sur la tête de distribution.The user is not likely to receive product on his fingers during the establishment of the drain member on the dispensing head.

Comme on le voit plus particulièrement à la figure 5, l'organe de vidange 60 vient en appui sur une zone de la seconde portion mobile 50 la plus éloignée de l'orifice de distribution 55. En outre, l'organe de vidange 60 vient en appui sur cette zone selon une direction sensiblement parallèle à l'axe du récipient, direction distincte de la direction de sortie du produit par l'orifice de distribution 55 qui est sensiblement perpendiculaire à l'axe du récipient. On limite ainsi les risques que l'utilisateur reçoive des projections de produit lorsqu'il met en place l'organe de vidange 60.As can be seen more particularly in FIG. 5, the emptying member 60 comes to bear on an area of the second movable portion 50 farthest from the dispensing orifice 55. In addition, the emptying member 60 comes resting on this zone in a direction substantially parallel to the axis of the container, direction distinct from the outlet direction of the product by the dispensing orifice 55 which is substantially perpendicular to the axis of the container. This limits the risks that the user receives product splashes when setting up the drain member 60.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit.Of course, the invention is not limited to the embodiment which has just been described.

Au lieu d'être retenu sur le récipient par un film de protection 70, l'organe de vidange 60 peut être retenu sur le récipient par deux bras 71 enlaçant le récipient sur une partie de sa périphérie comme on l'a illustré à la figure 8. Les deux bras 71 peuvent par exemple être réalisés d'un seul tenant avec l'organe de vidange auquel ils sont reliés par des ponts de matière sécables. Il suffit alors de rompre ces ponts de matière pour séparer les bras 71 de l'organe de vidange 60 avant d'utiliser celui-ci pour vider le récipient. L'utilisateur peut là encore distribuer du produit de façon classique sans que l'organe de vidange 60, toujours maintenu sur le récipient, ne gêne la distribution.Instead of being retained on the container by a protective film 70, the emptying member 60 can be retained on the container by two arms 71 embracing the container on a part of its periphery as illustrated in FIG. 8. The two arms 71 may for example be made in one piece with the drain member to which they are connected by breakable material bridges. It is then sufficient to break these bridges of material to separate the arms 71 of the drain member 60 before using it to empty the container. The user can again distribute the product in a conventional manner without the drain member 60, still held on the container, interferes with the distribution.

En variante encore, l'organe de vidange 60 peut être retenu sur le récipient par un anneau 72 encliqueté sur le fond du récipient comme représenté à la figure 6. Là encore, l'anneau 72 peut être réalisé d'un seul tenant avec l'organe de vidange auquel il est relié par des ponts de matière sécables. Un tel anneau peut aussi en variante être retenu entre le diffuseur et le récipient, non pas par encliquetage, mais par serrage. On choisira un anneau de diamètre interne sensiblement supérieur au diamètre externe du diffuseur et sensiblement inférieur au diamètre externe du récipient de manière à ce que l'anneau puisse être enfilé autour du diffuseur jusqu'à venir se serrer sur l'extrémité supérieure du récipient comme on le voit à la figure 7. L'utilisateur peut là encore distribuer du produit de façon classique sans que l'organe de vidange 60, toujours maintenu sur le récipient, ne gêne la distribution.In another variant, the emptying member 60 may be retained on the container by a ring 72 snapped onto the bottom of the container as shown in FIG. 6. Again, the ring 72 may be made in one piece with the drain member to which it is connected by breakable material bridges. Such a ring can also alternatively be retained between the diffuser and the container, not by snapping, but by clamping. We will choose a ring of internal diameter substantially greater than the outer diameter of the diffuser and substantially less than the outer diameter of the container so that the ring can be threaded around the diffuser until it comes to tighten on the upper end of the container as seen in Figure 7. The user can again distribute the product in a conventional manner without the emptying member 60, always held on the container, hinders the distribution.

Selon une autre variante illustrée à la figure 11, l'organe de vidange peut initialement être réalisé d'un seul tenant avec la tête de distribution, et par exemple avec une languette d'inviolabilité 74 initialement prévue au-dessus de la portion mobile 50 de la tête de distribution. L'organe de vidange 160 est alors relié à la languette d'inviolabilité par des ponts de matière sécables 73, la languette 74 étant elle-même reliée par des ponts de matière à la paroi transversale 42 de la portion fixe 40 de la tête de distribution. Avant une première utilisation, la languette 74 et l'organe de vidange sont désolidarisés de la tête de distribution. Selon ce mode de réalisation, on peut prévoir que la tête de distribution comporte une fente 48 dans sa paroi latérale 41 dans laquelle l'utilisateur peut introduire l'organe de vidange 160 de façon à le maintenir solidaire du dispositif pendant toute la durée d'utilisation normale du dispositif.According to another variant illustrated in FIG. 11, the emptying member may initially be made in one piece with the dispensing head, and for example with a tamper evident tab 74 initially provided above the moving portion 50. of the dispensing head. The emptying member 160 is then connected to the tamper-evident tongue by bridges of breakable material 73, the tongue 74 being itself connected by material bridges to the transverse wall 42 of the fixed portion 40 of the head of the distribution. Before a first use, the tongue 74 and the emptying member are separated from the dispensing head. According to this embodiment, it can be provided that the dispensing head has a slot 48 in its side wall 41 in which the user can introduce the emptying member 160 so as to maintain it integral with the device for the duration of normal use of the device.

Au lieu d'être réalisé d'un seul tenant avec une languette d'inviolabilité, l'organe de vidange peut être réalisé d'un seul tenant avec une autre partie de la tête de distribution, par exemple avec la jupe 41 à laquelle il est relié par des ponts de matière sécables. Dans ce cas non illustré, l'organe de vidange ne sera désolidarisé de la tête de distribution qu'en fin d'utilisation normale du dispositif, à savoir jusqu'à ce qu'on souhaite vidanger le récipient. Il ne sera alors pas nécessaire de prévoir une fente dans la jupe pour venir loger l'organe de vidange.Instead of being made in one piece with a tamper-evident tab, the emptying member can be made in one piece with another part of the dispensing head, for example with the skirt 41 to which it is connected by bridges of breakable material. In this case not illustrated, the emptying member will be detached from the dispensing head at the end of normal use of the device, namely until it is desired to empty the container. It will not be necessary to provide a slot in the skirt to come to house the drain member.

L'organe de vidange peut aussi avoir une forme différente de celle illustrée à la figure 3. En particulier, l'organe de vidange 160 représenté à la figure 11 sur la tête de distribution avant une première utilisation, et illustré isolément à la figure 9, comporte une paroi 161 incurvée entre ses deux bords latéraux 164 et un bord inférieur 163 destiné à venir en appui sur la portion mobile 50 de la tête de distribution. La paroi 161 est cette fois munie d'un rebord transversal 165 à proximité de son bord inférieur 163, qui s'étend transversalement à la paroi 161, entre ses deux bords latéraux 164. Le rebord transversal 165 est destiné à venir en butée avec la première portion de la tête de distribution. Comme on le voit plus précisément sur la figure 10 lorsque l'organe de vidange 160 est en position d'actionnement, le rebord transversal 165 vient en butée avec le rebord 46 de la portion fixe 40 de la tête de distribution pour s'opposer au retour de la portion mobile 50 de la tête de distribution et maintenir la valve actionnée.The emptying member may also have a shape different from that illustrated in FIG. 3. In particular, the emptying member 160 shown in FIG. 11 on the dispensing head before a first use, and illustrated in isolation in FIG. , has a wall 161 curved between its two side edges 164 and a lower edge 163 intended to bear on the movable portion 50 of the dispensing head. The wall 161 is this time provided with a transverse flange 165 near its lower edge 163, which extends transversely to the wall 161, between its two lateral edges 164. The transverse flange 165 is intended for abut with the first portion of the dispensing head. As can be seen more precisely in FIG. 10 when the emptying member 160 is in the actuating position, the transverse flange 165 abuts with the rim 46 of the fixed portion 40 of the dispensing head to oppose the return of the movable portion 50 of the dispensing head and maintain the actuated valve.

Selon un autre mode de réalisation illustré figures 12 et 13, l'organe de vidange 260 comporte une paroi incurvée 261 reliée à son extrémité supérieure 262 par une paroi transversale 269 à un anneau 268. L'anneau 268 est destiné à venir se fixer sur la jupe 41 de la portion fixe de la tête de distribution en position d'actionnement de l'organe de vidange. Des ergots 265 sont prévus sur le bord inférieur 263 de la paroi 261, les ergots 265 s'étendant transversalement à la paroi 261, sans déborder les bords latéraux 264, pour venir se loger sous le rebord 46 de la portion fixe de la tête de distribution. Dans cette position, le bord inférieur 262 de la paroi 261 vient appuyer sur le rebord 52 pour actionner la valve. Des fentes verticales 266 sont en outre prévues sur la paroi 261 pour obtenir deux tiges 267 souples qui facilitent le positionnement des ergots sous le rebord 46. Au lieu d'utiliser des ergots transversaux 265, on peut prévoir en variante des ergots formés dans le prolongement latéral des bords latéraux 264 de manière à former un hameçon comme dans le mode de réalisation de la figure 3.According to another embodiment illustrated in FIGS. 12 and 13, the emptying member 260 comprises a curved wall 261 connected at its upper end 262 by a transverse wall 269 to a ring 268. The ring 268 is intended to be fixed on the skirt 41 of the fixed portion of the dispensing head in the operating position of the emptying member. Lugs 265 are provided on the lower edge 263 of the wall 261, the lugs 265 extending transversely to the wall 261, without overflowing the lateral edges 264, to be housed under the flange 46 of the fixed portion of the head of the distribution. In this position, the lower edge 262 of the wall 261 presses on the flange 52 to actuate the valve. Vertical slots 266 are further provided on the wall 261 to obtain two flexible rods 267 which facilitate the positioning of the lugs under the flange 46. Instead of using transverse lugs 265, it is possible, in a variant, to provide lugs formed in the extension. lateral side edges 264 so as to form a hook as in the embodiment of FIG.

Dans la variante illustrée sur les figures 12 et 13, l'organe de vidange 260 comporte aussi un cache 90 destiné à être mis en regard de l'orifice de distribution 55 lorsque l'organe de vidange est placé dans sa position d'actionnement illustrée à la figure 13. Le cache 90 est formé par une paroi prolongeant le bord supérieur de l'anneau 268, à l'opposé de la paroi 261. Ce cache 90 limite la diffusion du produit et/ou du gaz propulseur dans l'air lors de la vidange. Le produit vidangé s'écoule en effet le long de la paroi formant le cache puis le long du récipient.In the variant illustrated in FIGS. 12 and 13, the emptying member 260 also includes a cover 90 intended to be placed opposite the dispensing orifice 55 when the emptying member is placed in its illustrated operating position. in Figure 13. The cover 90 is formed by a wall extending the upper edge of the ring 268, opposite the wall 261. This cover 90 limits the diffusion of the product and / or propellant into the air when emptying. The drained product flows indeed along the wall forming the cover and along the container.

Un tel cache peut également être prévu dans les autres modes de réalisation décrits notamment sur les figures 6 à 8, l'un des bras 71 de l'organe de vidange 60 illustré à la figure 8 se prolongeant par exemple jusqu'à former un cache diamétralement opposé à l'organe de vidange 60.Such a cover can also be provided in the other embodiments described in particular in Figures 6 to 8, one of the arms 71 of the drain member 60 illustrated in Figure 8 extending for example to form a cache diametrically opposed to the drain member 60.

Selon une autre variante illustrée sur les figures 14 à 16, l'organe de vidange 360 est, comme dans la variante illustrée à la figure 11, initialement réalisé d'un seul tenant avec la tête de distribution. Comme on le voit à la figure 14, l'organe de vidange est relié par des ponts de matière 75 à la paroi transversale 42 de la portion fixe 40 de la tête de distribution et s'étend au-dessus de la portion mobile 50 de la tête de distribution. L'organe de vidange 260, illustré isolément à la figure 15, comporte une paroi plane 361 dont une extrémité 362 se termine par un bord droit qui est relié à la paroi transversale 42 de la portion fixe 40. La paroi plane 361 est de forme générale tronconique et comporte un décrochement 363 de sorte que l'extrémité 362 est rétrécie. A l'opposé de l'extrémité 362, la paroi 361 se termine par un bord 364 convexe vers l'extérieur, qui suit le contour de la jupe cylindrique 41 de la portion fixe. Une paroi incurvée 365 s'étend transversalement à la paroi plane 361, en retrait du bord 364, vers l'intérieur de la tête de distribution.According to another variant illustrated in Figures 14 to 16, the emptying member 360 is, as in the variant illustrated in Figure 11, initially made in one piece with the dispensing head. As seen in FIG. 14, the emptying member is connected by material bridges 75 to the transverse wall 42 of the fixed portion 40 of the dispensing head and extends above the movable portion 50 of the dispensing head. The emptying member 260, illustrated in isolation in FIG. 15, comprises a plane wall 361 whose end 362 ends with a straight edge which is connected to the transverse wall 42 of the fixed portion 40. The flat wall 361 is of a shape generally frustoconical and has a recess 363 so that the end 362 is narrowed. Opposite the end 362, the wall 361 ends with an edge 364 convex outwards, which follows the contour of the cylindrical skirt 41 of the fixed portion. A curved wall 365 extends transversely to the plane wall 361, set back from the edge 364, towards the inside of the dispensing head.

Pour pouvoir distribuer le produit, l'utilisateur désolidarise l'organe de vidange 360 de la portion fixe 40 de la tête de distribution pour pouvoir accéder à la surface d'actionnement 51. En fin d'utilisation, lorsque l'utilisateur souhaite vidanger le récipient, il place l'extrémité rétrécie 362 de la paroi plane 361 de l'organe de vidange 360 au travers de l'ouverture 44 formée dans la paroi transversale 42, à l'avant de la surface d'actionnement 51 c'est-à-dire derrière la buse 80. Une fois placé dans cette position illustrée à la figure 16, la surface inférieure 362a de l'extrémité 362 vient en appui sur la portion mobile 50 de la tête de distribution de manière à la déplacer et à actionner la valve. La surface supérieure 362b de l'extrémité 362 vient en butée contre la paroi transversale 42 de la portion fixe 40 de la tête de distribution de façon à maintenir l'organe de vidange en appui sur la portion mobile 50. L'extrémité rétrécie 362 pourrait en outre avantageusement être plus épaisse sur une partie d'extrémité de façon à limiter encore les risques que l'organe mobile ne quitte sa position de vidange.In order to be able to dispense the product, the user disengages the emptying member 360 from the fixed portion 40 of the dispensing head in order to be able to access the actuating surface 51. At the end of use, when the user wishes to empty the container, it places the narrowed end 362 of the planar wall 361 of the drain member 360 through the opening 44 formed in the transverse wall 42, in front of the actuating surface 51 that is to say behind the nozzle 80. Once placed in this position illustrated in FIG. 16, the lower surface 362a of the end 362 bears on the movable portion 50 of the dispensing head so as to move and actuate it the valve. The upper surface 362b of the end 362 abuts against the transverse wall 42 of the fixed portion 40 of the dispensing head so as to keep the drain member bearing on the movable portion 50. The narrowed end 362 could further advantageously be thicker on an end portion so as to further limit the risk that the movable member leaves its emptying position.

Là encore, l'extrémité 362 de l'organe de vidange est introduite à l'arrière de l'orifice de distribution sans passer du côté du plan P tangent à l'orifice du côté duquel sort le produit. L'utilisateur ne risque donc pas de recevoir du produit sur ses doigts lors de la mise en place de l'organe de vidange sur la tête de distribution.Again, the end 362 of the drain member is introduced at the rear of the dispensing orifice without passing on the side of the plane P tangent to the orifice from which the product comes out. The user is therefore unlikely to receive product on his fingers during the introduction of the emptying member on the dispensing head.

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'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
