Description

La présente invention concerne un capot de distribution destiné à être associé à un récipient pressurisé du type «bombe aérosol».The present invention relates to a distribution cover intended to be associated with a pressurized container of the “aerosol can” type.

Les capots de distribution connus et utilisés jusqu'ici sont généralement réalisés en deux parties, l'une fixe, l'autre mobile, la partie fixe formée par le corps de capot étant assujettie à la partie supérieure du récipient pressurisé associé tandis que la partie mobile, sous forme de bouton-poussoir, vient s'adapter sur l'organe de sortie de la valve dont est doté le récipient pressurisé. La valve est le plus souvent disposée sur une coupelle elle-même fixée par un bourrelet annulaire de sertissage sur la partie supérieure du corps de récipient. De façon classique, le bouton-poussoir est logé à l'intérieur du corps de capot; il peut comporter une canalisation coudée en équerre dont la branche axiale vient coopérer avec l'organe de sortie de la valve et dont la branche radiale se termine par une buse d'éjection, laquelle est disposée au droit d'une fenêtre pratiquée dans la paroi latérale du corps de capot.The distribution covers known and used hitherto are generally made in two parts, one fixed, the other mobile, the fixed part formed by the cover body being secured to the upper part of the associated pressurized container while the part mobile, in the form of a push button, fits on the valve outlet member which is fitted with the pressurized container. The valve is most often arranged on a cup itself fixed by an annular bead of crimping on the upper part of the container body. Conventionally, the push button is housed inside the hood body; it may include a pipe bent at an angle, the axial branch of which comes to cooperate with the outlet member of the valve and the radial branch of which ends in an ejection nozzle, which is arranged in line with a window made in the wall side of the hood body.

Les capots de distribution de ce genre peuvent être avantageusement réalisés d'une seule pièce par moulage de matière plastique auquel cas, le bouton-poussoir est articulé par une charnière venue de moulage par rapport au corps fixe du capot. Ce type de capot présente, en général, une jupe intérieure pourvue d'organes d'accrochage tels que des ergots ou un jonc périphérique assurant la fixation par encliquetage du corps de capot sur le bourrelet de sertissage de la coupelle porte-valve. C'est le cas par exemple du capot de distribution décrit dans le brevet français 1 406 177; ce capot est réalisé d'une seule pièce par moulage de matière plastique; il comporte une partie fixe consistant en un corps de capot solidarisé avec le récipient pressurisé par encliquetage d'une jupe intérieure sur le bourrelet de sertissage de la coupelle porte-valve; il comporte également une partie mobile consistant en un bouton-poussoir qui est disposé partiellement à l'intérieur du corps de capot et coopère avec l'organe de sortie de la valve équipant le récipient pressurisé; le bouton-poussoir comporte une canalisation mettant en communication l'organe de sortie de la valve avec und buse d'éjection et il est articulé par une charnière venue de moulage par rapport au corps de capot.Distribution covers of this kind can advantageously be made in one piece by molding of plastic material in which case, the push button is articulated by a hinge coming from molding relative to the fixed body of the cover. This type of cover generally has an inner skirt provided with hooking members such as lugs or a peripheral ring ensuring the snap-fastening of the cover body to the crimping bead of the valve-holder cup. This is the case, for example, of the distribution cover described in French patent 1,406,177; this cover is made in one piece by plastic molding; it comprises a fixed part consisting of a cover body secured to the pressurized container by snap-fastening of an internal skirt on the crimping bead of the valve-holder cup; it also includes a movable part consisting of a push-button which is partially disposed inside the cover body and cooperates with the outlet member of the valve equipping the pressurized container; the push-button comprises a pipe putting the valve outlet member in communication with an ejection nozzle and it is articulated by a hinge coming from molding relative to the cover body.

Toutefois, de tels capots soulèvent deux sortes de difficultés: l'une au moulage, l'autre à la mise en place du capot sur le récipient pressurisé associé. En effet, les capots de distribution ont généralement une configuration complexe nécessitant pour leur moulage d'une seule pièce, des moules coûteux à fabriquer et compliquant aussi les opérations de démoulage. En outre, la plupart des capots de distribution actuels ne se prêtent pas bien, en raison de leur conception, à la mise en place automatique, quasiment sans intervention manuelle, sur les récipients pressurisés.However, such covers raise two kinds of difficulties: one in molding, the other in the establishment of the cover on the associated pressurized container. In fact, the distribution covers generally have a complex configuration requiring for their molding in one piece, molds which are expensive to manufacture and which also complicate the demolding operations. In addition, most of the current distribution covers do not lend themselves, due to their design, to automatic positioning, almost without manual intervention, on pressurized containers.

La présente invention vise à remédier au double inconvénient précité et à cet effet, elle se propose de décrire un capot de distribution réalisé d'une seule pièce, de forme particulièrement simple permettant à la fois une économie de matière première par rapport aux capots de distribution classiques et une mise en place simple et rapide - pouvant faire l'objet d'une mécanisation poussée - sur un récipient pressurisé. Le corps du capot selon l'invention ne comporte plus de jupe intérieure servant à son accrochage sur la coupelle porte-valve mais sa paroi latérale est pourvue d'un jonc annulaire, continu ou discontinu destiné à s'encliqueter à l'intérieur d'une gorge de retenue préformée pratiquée sur le corps du récipient pressurisé. En outre, le bouton-poussoir est disposé à l'intérieur du corps de capot entre deux ailes de guidage solidaires dudit corps, ces deux ailes de guidage venant en appui sur la coupelle porte-valve du récipient pressurisé. Les deux ailes de guidage servent ainsi de butée limitant le mouvement d'enfoncement du capot sur le récipient pressurisé au moment de sa fixation par encliquetage et accroissent également la résistance à l'écrasement des capots fixés sur les récipients pressurisés, lors du stockage et du transport, en particulier lorsque ces ensembles sont empilés les uns sur les autres. Avantageusement, les deux ailes de guidage sont pourvues de deux tétons saillants s'emboîtant à l'intérieur de la coupelle porte-valve et assurant au montage son précentrage sur le récipient pressurisé associé, avant l'encliquetage du jonc continu ou discontinu du corps de capot dans la gorge de retenue du récipient pressurisé.The present invention aims to remedy the aforementioned double drawback and to this end, it proposes to describe a distribution cover made in one piece, of particularly simple shape allowing both a saving of raw material compared to the distribution covers conventional and a simple and fast installation - which can be the object of a deep mechanization - on a pressurized container. The body of the cover according to the invention no longer has an internal skirt used for hooking it onto the valve-holder cup, but its side wall is provided with an annular ring, continuous or discontinuous intended to snap inside. a preformed retaining groove made on the body of the pressurized container. In addition, the push-button is disposed inside the cover body between two guide wings integral with said body, these two guide wings coming to bear on the valve-carrying cup of the pressurized container. The two guide wings thus serve as a stop limiting the depression movement of the cover on the pressurized container at the time of its snap fastening and also increase the crushing resistance of the covers fixed on the pressurized containers, during storage and transport, especially when these sets are stacked on top of each other. Advantageously, the two guide wings are provided with two projecting studs which fit inside the valve-holder cup and which assures its mounting its pre-centering on the associated pressurized container, before the continuous or discontinuous rod of the body is snapped in. cover in the retaining groove of the pressurized container.

Dans la demande de brevet français n° 8012112 déposée le 30 Mai 1980, (FR-A-24 83 369) on a également décrit un capot de distribution destiné à être associé à un récipient pressurisé dont la paroi latérale comporte une gorge de retenue préformée servant à la fixation par encliquetage du corps de capot. Le capot de distribution faisant l'objet de cette demande de brevet offre sensiblement les mêmes avantages que celui de la présente invention mais présente une structure différente du fait qu'il est constitué de deux pièces s'emboîtant l'une dans l'autre.In French patent application n ° 8012112 filed on May 30, 1980, (FR-A-24 83 369), a distribution cover has also been described intended to be associated with a pressurized container whose side wall has a preformed retaining groove used for snap-fastening of the hood body. The distribution cover which is the subject of this patent application offers substantially the same advantages as that of the present invention but has a different structure from the fact that it consists of two parts which fit into one another.

La présente invention a donc pour objet un capot de distribution destiné à être associé à un récipient pressurisé du type «bombe aérosol», ce capot de distribution étant réalisé, d'une seule pièce, par moulage de matière plastique et comportant deux parties, l'une fixe et l'autre mobile, la partie fixe consistant en un corps de capot solidarisé par encliquetage avec le récipient pressurisé, la partie mobile du capot de distribution consistant en un bouton-poussoir, qui est disposé au moins partiellement à l'intérieur du corps de capot et qui coopère avec l'organe de sortie de la valve équipant le récipient associé, ledit bouton-poussoir comportant une canalisation mettant en communication l'organe de sortie de la valve avec une buse d'éjection, une fenêtre étant pratiquée dans la paroi latérale du corps de capot au droit de la buse d'éjection du bouton-poussoir, ce dernier étant articulé par une charnière venue de moulage par rapport au corps de capot, caractérisé par le fait que, de façon connue en soi, la paroi latérale du corps de capot, est pourvue d'un jonc continu ou discontinu, destiné à s'encliqueter à l'intérieur d'une gorge de retenue préformée pratiquée sur le corps du récipient pressurisé associé, et qu'à l'intérieur du corps de capot, le bouton-poussoir est disposé entre deux ailes de guidage solidaires du corps de capot, ces deux ailes de guidage venant sensiblement en appui sur le bourrelet annulaire de sertissage de la coupelle porte-valve du récipient associé.The present invention therefore relates to a distribution cover intended to be associated with a pressurized container of the “aerosol can” type, this distribution cover being produced in one piece by molding of plastic material and comprising two parts, l '' one fixed and the other mobile, the fixed part consisting of a cover body secured by snap-fastening to the pressurized container, the mobile part of the dispensing cover consisting of a push button, which is arranged at least partially inside of the cover body and which cooperates with the outlet member of the valve fitted to the associated container, said push button comprising a pipe bringing the valve outlet member into communication with an ejection nozzle, a window being provided in the side wall of the cover body to the right of the push button ejection nozzle, the latter being articulated by a hinge molded in relation to the cover body, characterized in that, f side known per se, the side wall of the cover body, is provided with a continuous or discontinuous rod, intended to snap inside a preformed retaining groove formed on the body of the associated pressurized container, and that inside the body of cover, the push button is arranged between two guide wings integral with the cover body, these two guide wings coming to bear substantially on the annular bead for crimping the valve-holder cup of the associated container.

Selon une caractéristique avantageuse de l'invention, le corps de capot comporte des organes assurant son précentrage sur le récipient pressurisé, au moment de sa mise en place sur ce dernier, avant l'encliquetage du jonc du corps de capot dans la gorge de retenue du récipient pressurisé. Les organes de précentrage précités sont constitués par deux tétons s'étendant parallèlement à l'axe du corps de capot et faisant saillie par rapport aux deux ailes de guidage, ces deux tétons étant destinés à s'emboîter à l'intérieur de la coupelle porte-valve du récipient pressurisé.According to an advantageous characteristic of the invention, the cover body comprises members ensuring its pre-centering on the pressurized container, at the time of its installation on the latter, before the snap of the ring of the cover body in the retaining groove of the pressurized container. The aforementioned pre-centering members consist of two studs extending parallel to the axis of the cover body and projecting with respect to the two guide wings, these two studs being intended to fit inside the cup holder -valve of the pressurized container.

Dans un mode préféré de réalisation, les deux ailes de guidage, entre lesquelles le bouton-poussoir peut pivoter autour de sa charnière d'articulation, se raccordent à la paroi supérieure du corps de capot; chacune des ailes de guidage relie l'un des deux bords de la fenêtre du corps de capot, où est disposée la buse d'éjection du bouton-poussoir, au bord correspondant d'une encoche diamétralement opposée pratiquée dans la paroi latérale du corps de capot; les deux ailes de guidage sont sensiblement symétriques par rapport à un plan axial du capot et sont convergentes en direction de la fenêtre dudit corps, au droit de laquelle est disposée la buse d'éjection du bouton-poussoir; le bouton-poussoir comporte une languette dont les parois coopèrent avec les parois des ailes de guidage pour assurer le débattement du bouton-poussoir sensiblement sur ledit récipient dans un plan passant par l'axe de coulissement de l'organe de sortie de la valve et perpendiculaire à l'axe de la charnière d'articulation.In a preferred embodiment, the two guide wings, between which the push button can pivot around its articulation hinge, are connected to the upper wall of the cover body; each of the guide wings connects one of the two edges of the window of the cover body, where the push button ejection nozzle is disposed, to the corresponding edge of a diametrically opposite notch formed in the side wall of the body hood; the two guide wings are substantially symmetrical with respect to an axial plane of the cover and are convergent in the direction of the window of said body, to the right of which is disposed the ejection nozzle of the push button; the push-button has a tongue, the walls of which cooperate with the walls of the guide wings to ensure the movement of the push-button substantially on said container in a plane passing through the sliding axis of the valve outlet member, and perpendicular to the axis of the hinge.

Avantageusement, la buse d'éjection est portée par une paroi frontale du bouton-poussoir qui obture sensiblement la fenêtre pratiquée dans le corps de capot; la charnière d'articulation est ménagée dans la zone de raccordement entre la base de la paroi frontale du bouton-poussoir et le fond de la fenêtre précitée. En variante, la charnière d'articulation est constituée de deux bouts d'axe venus de moulage reliant la paroi du bouton-poussoir, où est ménagée la canalisation radiale, aux deux ailes de guidage.Advantageously, the ejection nozzle is carried by a front wall of the push button which substantially closes the window made in the hood body; the articulation hinge is formed in the connection zone between the base of the front wall of the push button and the bottom of the aforementioned window. As a variant, the articulation hinge consists of two ends of an axis from the molding connecting the wall of the push button, where the radial pipe is formed, to the two guide wings.

Selon une autre caractéristique avantageuse, l'ouverture pratiquée dans la paroi supérieure du corps de capot pour permettre la manoeuvre du bouton-poussoir qui y est logé à l'intérieur est obturé, avant la première utilisation de l'ensemble formé par le capot de distribution et le récipient pressurisé associé, par une plaque d'inviolabilité reliée par des attaches cassables, venues de moulage, à la paroi supérieure précitée. Si la plaque d'inviolabilité n'a pas été arrachée du capot associé au récipient, l'utilisateur est alors certain que l'ensemble qu acquiert n-a pas été touché ou du moins renferme encore la totalité du produit à distribuer conditionné par le fabricant dans le récipient pressurisé; par contre, la fracture ou l'arrachage de la plaque d'inviolabilité signifie que le bouton-poussoir associé à la valve a été manoeuvré au moins une fois et que le récipient a donc été soumis à une utilisation antérieure.According to another advantageous characteristic, the opening made in the upper wall of the cover body to allow the operation of the push button which is housed therein is closed, before the first use of the assembly formed by the cover distribution and the associated pressurized container, by a tamper-evident plate connected by breakable fasteners, molded, to the above-mentioned upper wall. If the tamper plate has not been torn off the cover associated with the container, the user is certain that all that acquires n - not being touched or at least still contains all of the product to distribute conditioned by manufacturer in pressurized container; on the other hand, the fracture or the tearing of the tamper-evident plate means that the push button associated with the valve has been operated at least once and that the container has therefore been subjected to a prior use.

De préférence, la plaque d'inviolabilité est pourvue dans sa partie qui est disposée au centre de la paroi supérieure du corps de capot d'une patte pré-découpée déformable permettant la manoeuvre en usine du bouton-pressoir logé à l'intérieur du corps de capot, aux fins de vérifications du bon fonctionnement de l'ensemble.Preferably, the tamper-evident plate is provided in its part which is arranged in the center of the upper wall of the hood body with a deformable pre-cut tab allowing the factory operation of the press button housed inside the body. cover, for the purpose of verifying the proper functioning of the assembly.

Il est clair que le capot selon l'invention peut coopérer selon la forme de l'extrémité concernée du bouton-poussoir, soit avec une valve à tige émergente, soit avec une valve sans tige émergente.It is clear that the cover according to the invention can cooperate according to the shape of the end concerned of the push-button, either with a valve with an emerging stem, or with a valve without an emerging stem.

La présente invention a également pour objet un ensemble formé, en premier lieu, d'un récipient pressurisé du type «bombe aérosol» et, en deuxième lieu, d'un capot de distribution moulé d'une seule pièce, destiné à s'adapter sur une extrémité du récipient précité, la paroi latérale du récipient associée comportant une gorge de retenue préformée servant à la fixation par encliquetage du corps du capot caractérisé par le fait que le capot de distribution est un capot du type ci-dessus défini.The present invention also relates to an assembly formed, firstly, of a pressurized container of the “aerosol can” type and, secondly, of a distribution cover molded in one piece, intended to adapt on one end of the aforementioned container, the side wall of the associated container comprising a preformed retaining groove used for snap-fastening of the body of the cover, characterized in that the distribution cover is a cover of the type defined above.

Pour mieux faire comprendre l'objet de la présente invention, on va en décrire ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the present invention, there will be described below, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

En se référant aux figures 1 à 3 du dessin, on voit que l'on a désigné par 1 dans son ensemble, un récipient pressurisé du type «bombe aérosol» obtenu, par exemple, par matriçage et formage d'une pastille d'aluminium. Le récipient 1 comporte un fond (non représenté), une paroi latérale cylindrique 2 et une partie supérieure 3 en forme d'ogive. Une coupelle porte-valve est fixée, par un bourrelet annulaire de sertissage 4, à l'extrémité de l'ogive 3.Referring to Figures 1 to 3 of the drawing, we see that we have designated by 1 as a whole, a pressurized container of the "aerosol can" type obtained, for example, by stamping and forming an aluminum pellet . The container 1 has a bottom (not shown), a cylindrical side wall 2 and an upper part 3 in the form of a warhead. A valve holder cup is fixed, by an annular crimping bead 4, to the end of the warhead 3.

Dans la partie centrale de la coupelle porte-valve, est disposée une valve dont l'organe de sortie est constitué, de façon classique, par un tube 5 pouvant coulisser selon son axe. Dans la zone de raccordement entre la paroi latérale cylindrique 2 du récipient et l'ogive 3 est pratiquée une gorge périphérique de retenue 6.In the central part of the valve holder cup, a valve is arranged, the outlet member of which is conventionally constituted by a tube 5 which can slide along its axis. In the connection zone between the cylindrical side wall 2 of the container and the warhead 3, a peripheral retaining groove 6 is formed.

Sur la partie supérieure du récipient pressurisé 1, de type connu, vient s'adapter un capot de distribution réalisé d'une seule pièce par moulage de matière plastique. Un tel capot comporte pour l'essentiel deux parties, d'une part, un corps de capot désigné par 10 dans son ensemble et, d'autre part, un bouton-poussoir 20 articulé audit corps de capot.On the upper part of the pressurized container 1, of known type, is fitted a distribution cover made in one piece by plastic molding. Such a cover essentially comprises two parts, on the one hand, a cover body designated by 10 as a whole and, on the other hand, a push button 20 articulated to said cover body.

La paroi latérale cylindrique 11 du corps de capot est pourvue intérieurement, à sa partie inférieure, d'un jonc continu 12 qui, par encliquetage à l'intérieur de la gorge de retenue 6, assure la fixation, de façon sensiblement irréversible, du capot sur la partie supérieure du récipient .The cylindrical side wall 11 of the cover body is provided internally, at its lower part, with a continuous rod 12 which, by snap-fastening inside the retaining groove 6, ensures the fixing, in a substantially irreversible manner, of the cover on the top of the container.

Une fenêtre 13 et une encoche diamétralement opposée 14 sont pratiquées dans la partie supérieure de la paroi latérale 11, dans sa zone de raccordement avec la paroi supérieure 15 du corps de capot 10. Les deux bords latéraux de la fenêtre 13 et de l'encoche 14 sont réunis deux à deux par deux ailes de guidage 16, 17 s'étendant à l'intérieur du corps de capot 10; les deux ailes de guidage sont disposés symétriquement de part et d'autre de l'axe du corps de capot et sont sensiblement convergentes en direction de la fenêtre 13, elles se raccordent à la paroi supérieure 15 du corps de capot.A window 13 and a diametrically opposite notch 14 are formed in the upper part of the side wall 11, in its zone of connection with the upper wall 15 of the cover body 10. The two lateral edges of the window 13 and of the notch 14 are joined two by two by two guide wings 16, 17 extending inside the cover body 10; the two guide wings are arranged symmetrically on either side of the axis of the cover body and are substantially convergent in the direction of the window 13, they are connected to the upper wall 15 of the cover body.

Une ouverture, dont deux bords opposés sont délimités par les deux ailes de guidage 16, 17, est pratiquée dans la paroi supérieure 15 du corps de capot. L'ouverture précitée s'étend depuis la partie centrale des deux ailes de guidage 16, 17 jusqu'à l'extrémité desdites ailes qui délimitent l'encoche 14. Elle est obturée par une plaque d'inviolabilité 18 reliée par des attaches cassables 19 venues de moulage avec la paroi supérieure 15 du corps de capot. Une patte prédécoupée 30 (figure 3) est prévue dans la partie de la plaque d'inviolabilité 18 qui est disposée au centre de la paroi supérieure 15. En usine, l'enfoncement de la patte prédécoupée 30 au moyen d'un outil permet d'actionner le bouton-poussoir 20 et de contrôler la pulvérisation du produit contenu dans le récipient 1, sans arrachement ni endommagement de la plaque d'inviolabilité 18.An opening, two opposite edges of which are delimited by the two guide wings 16, 17, is formed in the upper wall 15 of the cover body. The aforementioned opening extends from the central part of the two guide wings 16, 17 to the end of said wings which delimit the notch 14. It is closed by a tamper-evident plate 18 connected by breakable fasteners 19 comings of molding with the upper wall 15 of the cover body. A precut tab 30 (FIG. 3) is provided in the part of the tamper-evident plate 18 which is arranged in the center of the upper wall 15. In the factory, the depressing of the precut tab 30 by means of a tool makes it possible to 'actuate the push button 20 and control the spraying of the product contained in the container 1, without tearing off or damaging the tamper-evident plate 18.

Le bouton-poussoir 20 est disposé à l'intérieur du corps de capot 10, entre les deux ailes de guidage 16, 17. Il comporte une canalisation en équerre dans la branche axiale 21 de laquelle vient s'emboîter le tube de sortie 5 de la valve; la branche radiale 22 de la canalisation en équerre débouche par son extrémité 23 en vis-à-vis de l'orifice d'éjection d'une buse (non représentée). La buse d'éjection précitée est portée par une paroi frontale 24 du bouton-poussoir. La paroi frontale 24 précitée est disposée au droit de la fenêtre 13 pratiquée dans la paroi latérale 11 du corps de capot 10. L'ouverture définie par la fenêtre 13 est sensiblement obturée par la paroi frontale 24 du bouton-poussoir 20. Sur le fond de la fenêtre 13 se raccorde par une charnière 25 venue de moulage, la base de la paroi frontale 24 du bouton-poussoir 20. La charnière 25 constitue l'articulation autour de laquelle le bouton-poussoir 20 peut pivoter.The push button 20 is disposed inside the cover body 10, between the two guide wings 16, 17. It has a channel at right angles to the axial branch 21 of which the outlet tube 5 fits the valve; the radial branch 22 of the square pipe opens out at its end 23 opposite the ejection orifice of a nozzle (not shown). The aforementioned ejection nozzle is carried by a front wall 24 of the push button. The aforementioned front wall 24 is disposed in line with the window 13 formed in the side wall 11 of the cover body 10. The opening defined by the window 13 is substantially closed by the front wall 24 of the push button 20. On the bottom of the window 13 is connected by a hinge 25 coming from molding, the base of the front wall 24 of the push button 20. The hinge 25 constitutes the articulation around which the push button 20 can pivot.

Au droit de l'ouverture ménagée dans la paroi supérieure 15 du corps de capot 10, le bouton-poussoir 20 est pourvu d'une languette 26. Cette dernière comporte deux bords latéraux convergeant en direction de la fenêtre 13 du corps de capot et venant coopérer avec les deux ailes 16 et 17 pour assurer le guidage du bouton-poussoir 20 sensiblement dans un plan passant par l'axe de coulissement du tube de sortie 5 de la valve et perpendiculaire à l'axe de la charnière d'articulation 25, lorsque le bouton-poussoir est actionné. La languette 26 comporte à sa partie supérieure une dépression dans laquelle vient se loger le doigt de l'utilisateur qui agit sur le bouton-poussoir 20. Elle est également pourvue d'un retour sensiblement en équerre 27 de forme arrondie. L'encoche 14 a pour but de faciliter la manoeuvre d'enfoncement du bouton-poussoir 20 à l'intérieur du corps de capot 10.In line with the opening in the upper wall 15 of the cover body 10, the push button 20 is provided with a tongue 26. The latter has two lateral edges converging in the direction of the window 13 of the cover body and coming from cooperate with the two wings 16 and 17 to guide the push button 20 substantially in a plane passing through the sliding axis of the outlet tube 5 of the valve and perpendicular to the axis of the articulation hinge 25, when the push button is pressed. The tongue 26 has at its upper part a depression in which is housed the finger of the user who acts on the push button 20. It is also provided with a substantially square return 27 of rounded shape. The purpose of the notch 14 is to facilitate the pushing in operation of the push button 20 inside the cover body 10.

Dans la zone centrale des deux ailes de guidage 16, 17, sont prévus deux tétons 28 s'étendant parallèlement à l'axe du capot et disposés symétriquement de part et d'autre de ce dernier. Les deux tétons 28 précités, qui font saillie par rapport aux deux ailes de guidage 16, 17, sont destinés à s'emboîter à l'intérieur de la coupelle porte-valve où ils coopèrent avec la paroi intérieure circulaire du bourrelet de sertissage 4.In the central zone of the two guide wings 16, 17, two studs 28 are provided which extend parallel to the axis of the cover and are arranged symmetrically on either side of the latter. The two aforementioned pins 28, which project relative to the two guide wings 16, 17, are intended to fit inside the valve-holder cup where they cooperate with the circular inner wall of the crimping bead 4.

L'assemblage du capot de distribution qui vient d'être décrit sur le récipient pressurisé 1 peut être réalisé soit manuellement soit sur machine. Le corps de capot 10, qui est présenté au-dessus du récipient pressurisé 1, est emboîté sur la partie supérieure de celui-ci; pendant ce mouvement d'enfoncement les deux tétons 28 pénètrent à l'intérieur de la coupelle porte-valve et la coopération desdits tétons avec la paroi circulaire intérieure du bourrelet de sertissage 4 assurent le précentrage du corps de capot sur le récipient pressurisé; la manoeuvre d'enfoncement est poursuivie jusqu'à mise en appui des deux ailes de guidage 16 et 17 sur le bourrelet de sertissage 4 de la coupelle porte-valve et encliquetage du jonc périphérique 12 à l'intérieur de la gorge de retenue 6 du récipient pressurisé; le tube de sortie 5 de la valve se trouve automatiquement enfoncé à l'intérieur de la canalisation axiale 21 du bouton-poussoir. Il convient de noter que la mise en place du capot sur le récipient pressurisé 1 peut être effectuée sans aucune précaution particulière et sans risque d'enfoncement du tube de sortie 5 de la valve, étant donné que ce mouvement d'enfoncement est limité par la mise en appui des deux ailes de guidage 16 et 17 sur le bourrelet de sertissage 4 de la coupelle porte-valve.The assembly of the distribution cover which has just been described on the pressurized container 1 can be carried out either manually or on a machine. The cover body 10, which is presented above the pressurized container 1, is fitted onto the upper part of the latter; during this driving-in movement, the two studs 28 penetrate inside the valve-holder cup and the cooperation of said studs with the inner circular wall of the crimping bead 4 ensure the centering of the cover body on the pressurized container; the sinking operation is continued until the two guide wings 16 and 17 are supported on the crimping bead 4 of the valve-holder cup and snap-fastening of the peripheral ring 12 inside the retaining groove 6 of the pressurized container; the outlet tube 5 of the valve is automatically inserted inside the axial pipe 21 of the push button. It should be noted that the fitting of the cover on the pressurized container 1 can be carried out without any particular precaution and without risk of sinking of the outlet tube 5 of the valve, since this sinking movement is limited by the bearing of the two guide wings 16 and 17 on the crimping bead 4 of the valve holder cup.

Pour mettre en oeuvre l'ensemble formé par le récipient pressurisé 1 et le capot de distribution, l'utilisateur arrache la plaque d'inviolabilité 18, de façon à pouvoir enfoncer le bouton-poussoir 20 en agissant, à l'aide d'un doigt, sur la dépression ménagée sur la languette 26; la paroi supérieure 15 du corps de capot sert à limiter le débattement angulaire du bouton-poussoir 20 autour de sa charnière d'articulation 25 dans le sens opposé à celui qui correspond à un enfoncement du tube de sortie 5 de la valve et, par suite, à l'ouverture de ladite valve.To implement the assembly formed by the pressurized container 1 and the dispensing cover, the user tears off the tamper-evident plate 18, so as to be able to depress the push button 20 by acting, using a finger, on the depression formed on the tongue 26; the upper wall 15 of the cover body serves to limit the angular movement of the push button 20 around its articulation hinge 25 in the opposite direction to that which corresponds to a depression of the tube outlet 5 of the valve and, consequently, at the opening of said valve.

Sur la figure 4 on a représenté une variante de réalisation concernant l'articulation du bouton-poussoir 20 sur le corps de capot. Dans le mode de réalisation des figures 1 à 3, le bouton-poussoir 20 comporte une paroi frontale 24 articulée par la charnière 25 sur le fond de la fenêtre 13. Dans la variante de la figure 4, la paroi du bouton poussoir 20, où est aménagée la canalisation radiale 22, est reliée aux deux ailes de guidage 16, 17 par deux bouts d'axe coaxiaux 40; ces deux bouts d'axe coaxiaux 40 sont venus de moulage et constituent la charnière d'articulation du bouton-poussoir 20. Il est à noter que les deux bouts d'axe coaxiaux 40 ne subissent que peu de contrainte en cours de fonctionnement, du fait du faible débattement angulaire du bouton-poussoir nécessaire pour provoquer l'enfoncement du tube de sortie 5 de la valve et l'éjection du produit contenu dans le récipient et du fait aussi de la présence des deux ailes de guidage 16 et 17 servant à guider le débattement du bouton-poussoir 20 selon l'axe de coulissement du tube de sortie 5 de la valve et perpendiculairement aux bouts d'axe 40.In Figure 4 there is shown an alternative embodiment concerning the articulation of the push button 20 on the hood body. In the embodiment of Figures 1 to 3, the push button 20 has a front wall 24 hinged by the hinge 25 on the bottom of the window 13. In the variant of Figure 4, the wall of the push button 20, where is arranged the radial pipe 22, is connected to the two guide wings 16, 17 by two ends of coaxial axis 40; these two ends of coaxial axis 40 came from molding and constitute the hinge of articulation of the push button 20. It should be noted that the two ends of coaxial axis 40 undergo only little stress during operation, the due to the small angular movement of the push button necessary to cause the outlet tube 5 of the valve to sink and the product contained in the container to be ejected and also due to the presence of the two guide wings 16 and 17 serving to guide the travel of the push-button 20 along the sliding axis of the outlet tube 5 of the valve and perpendicular to the ends of the axis 40.

Il est bien entendu que le mode de réalisation ci-dessus décrit n'est aucunement limitatif et pourra donner lieu à toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiment described above is in no way limiting and may give rise to any desirable modifications without departing from the scope of the invention.
