Description

"Dispositif d'obturation d'un appareil applicateur de produit liquide quelconque et appareil applicateur utilisable avec ce dispositif". "Device for closing off an applicator device for any liquid product and applicator device usable with this device".
La présente invention a essentiellement pour objet un dispositif d'obturation d'un appareil applicateur de produit liquide plus ou moins visqueux, tel que par exemple du vernis à ongle.The present invention essentially relates to a device for closing a device for applying a more or less viscous liquid product, such as for example nail varnish.
Elle vise également un appareil applicateur utilisable avec ce dispositif.It also relates to an applicator device usable with this device.
On connait déjà des appareils applicateurs qui sont munis d'un pinceau applicateur en contact avec un produit contenu dans un réservoir et qui, d'une manière générale, sont obturables par un bouchon dont le montage sur le corps de l'appareil et le démontage commandent respectivement la mise hors service ou en position escamotée du pinceau applicateur et sa mise en service ou en position de sortie et d'utilisation.Applicator devices are already known which are provided with an applicator brush in contact with a product contained in a reservoir and which, in general, can be closed off by a plug, the mounting of which on the body of the device and the dismantling respectively control the deactivation or in the retracted position of the applicator brush and its commissioning or in the exit and use position.
De tels dispositifs sont par exemple décrits dans les documents DE-A-2 944 336 et DE-A-3 635 690.Such devices are for example described in documents DE-A-2 944 336 and DE-A-3 635 690.
Toutefois, dans ces documents, le bouchon actionne directement le pinceau applicateur à la fermeture ou à l'ouverture du récipient pour réaliser respectivement son escamotage ou sa mise en service. Il en résulte que le montage et le démontage du bouchon peuvent, à la longue, détériorer le pinceau, ou à tout le moins, altérer ses qualités de finesse.However, in these documents, the plug directly actuates the applicator brush when the container is closed or opened in order to carry out its retraction or its commissioning, respectively. As a result, the assembly and disassembly of the cap can, in the long run, deteriorate the brush, or at the very least, alter its qualities of finesse.
Aussi, la présente invention a pour but de remédier notamment aux inconvénients ci-dessus en proposant un dispositif d'obturation qui ne risque, en aucun cas, d'endommager le pinceau applicateur à la fermeture et à l'ouverture du récipient et qui, au surplus, permet une obturation sûre et positive qui s'oppose à la sortie accidentelle du liquide contenu dans le réservoir et demeurant en contact avec le pinceau applicateur.Also, the object of the present invention is to remedy the above drawbacks in particular by proposing a closure device which does not, in any case, risk damaging the applicator brush on closing and the opening of the container and which, moreover, allows a secure and positive closure which prevents the accidental exit of the liquid contained in the reservoir and remaining in contact with the applicator brush.
A cet effet, l'invention a pour objet un dispositif d'obturation d'un appareil applicateur de produit liquide quelconque plus ou moins visqueux qui est équipé d'un pinceau applicateur en contact avec le produit contenu dans un réservoir et qui est obturable par un bouchon dont le montage sur le corps de 1'appareil et le démontage commandent respectivement la mise hors service ou en position escamotée du pinceau applicateur et la mise en service ou en position de sortie et d'utilisation de ce pinceau applicateur, caractérisé en ce que ledit bouchon, à l'obturation du corps, actionne un fourreau ou analogue monté mobile dans ledit corps de façon à réaliser l'escamotage dans ce fourreau du pinceau applicateur logé à l'intérieur du fourreau et monté fixe dans le corps et, à l'ouverture du corps, actionne ledit fourreau en sens inverse pour dégager le pinceau applicateur du fourreau et permettre ainsi son utilisation après séparation du bouchon du corps de 1'appareil.To this end, the subject of the invention is a device for closing a device for applying any more or less viscous liquid product which is equipped with an applicator brush in contact with the product contained in a reservoir and which can be closed by a plug, the mounting of which on the body of the device and the dismantling respectively control the deactivation or in the retracted position of the applicator brush and the commissioning or in the position of exit and use of this applicator brush, characterized in that that said plug, when closing the body, actuates a sheath or the like mounted movably in said body so as to retract in this sheath the applicator brush housed inside the sheath and mounted fixedly in the body and, at opening the body, actuates said sheath in the opposite direction to disengage the applicator brush from the sheath and thus allow its use after separation of the plug from the body of the device.
On comprend donc déjà que le bouchon ne risque pas d'endommager le pinceau applicateur, puisqu'il agira seulement sur un fourreau mobile permettant de masquer complètement le pinceau ou bien de le mettre en position d'utilisation ou de sortie du fourreau.It is therefore already understood that the plug does not risk damaging the applicator brush, since it will act only on a movable sheath making it possible to completely hide the brush or else to put it in the position of use or out of the sheath.
Suivant une autre caractéristique de ce disposi if, le bouchon comporte une partie coopérant par vissage avec le fourreau mobile et une partie coopérant par butée avec le corps du récipient, pour réaliser, lors du vissage, l'escamotage dans le fourreau du pinceau applicateur qui demeure ainsi en contact intime avec le produit liquide contenu dans le réservoir.According to another characteristic of this arrangement, the stopper comprises a part cooperating by screwing with the movable sheath and a part cooperating by abutment with the body of the container, to produce, during the screwing, retraction in the sheath of the applicator brush which thus remains in intimate contact with the liquid product contained in the reservoir.
Autrement dit, le vissage du bouchon provoquera l'attraction du fourreau et l'escamotage du pinceau applicateur monté fixe dans le récipient.In other words, the screwing of the cap will cause the attraction of the sheath and the retraction of the applicator brush mounted fixed in the container.
Suivant encore une autre caractéristique de l'invention, le bouchon est intérieurement muni d'un ressort auquel est associée une bague que peut traverser le pinceau et coopérant avec un orifice formant siège dans le fourreau, dès le début du montage ou du vissage du bouchon sur ledit fourreau.According to yet another characteristic of the invention, the plug is internally provided with a spring with which is associated a ring which the brush can pass through and cooperating with an orifice forming a seat in the sheath, from the start of mounting or screwing the plug. on said sheath.
L'invention vise également un appareil applicateur utilisable avec un dispositif d'obturation répondant à l'une ou l'autre des caractéristiques ci-dessus, et caractérisé en ce que le fourreau est d'une part monté à coulissement étanche sur une partie du réservoir pour demeurer en communication permanente avec celui-ci et est d'autre part monté coulissant sans rotation dans le corps.The invention also relates to an applicator device which can be used with a closure device corresponding to one or the other of the above characteristics, and characterized in that the sheath is on the one hand mounted with leaktight sliding on a part of the reservoir to remain in permanent communication therewith and is on the other hand slidably mounted without rotation in the body.
cet appareil est encore caractérisé en ce que l'une des extrémités du fourreau est montée à coulissement étanche sur un élément tubulaire prolongeant le réservoir et situé dans l'axe du corps et du fourreau, tandis qu'un ressort, logé dans le fourreau, prend appui entre ladite extrémité et un clapet portant le pinceau applicateur solidaire du corps.this device is further characterized in that one of the ends of the sheath is mounted in leaktight sliding on a tubular element extending the tank and situated in the axis of the body and of the sheath, while a spring, housed in the sheath, is supported between said end and a valve carrying the applicator brush secured to the body.
Suivant une autre caractéristique de cet appareil, le ressort entourant une tige ou analogue logée dans le fourreau et reliant le clapet au corps, sollicite constamment l'extrémité du fourreau comportant l'orifice formant siège en appui sur ledit clapet. On précisera encore qu'au corps de l'appareil est associé un bouton-poussoir muni d'une lame-ressort susceptible de coopérer avec un épaulement du fourreau pour actionner ce dernier afin de délivrer du produit liquide au pinceau applicateur uniquement lorsque le bouchon est désolidarisé du corps.According to another characteristic of this device, the spring surrounding a rod or the like housed in the sheath and connecting the valve to the body, constantly urges the end of the sheath comprising the orifice forming a seat in abutment on said valve. It will also be specified that the body of the device is associated with a push button provided with a leaf spring capable of cooperating with a shoulder of the sheath in order to actuate the latter in order to deliver liquid product to the applicator brush only when the cap is disconnected from the body.
Le corps de l'appareil pourra contituer une tête raccordable sur le réservoir par tout moyen approprié tel que vissage. Alternativement, ce corps pourra former un élément unique comportant un réservoir surmonté par une partie tubulaire comportant le fourreau et tous ses éléments associés.The body of the device may constitute a head which can be connected to the tank by any suitable means such as screwing. Alternatively, this body may form a single element comprising a reservoir surmounted by a tubular part comprising the sheath and all of its associated elements.
Selon encore une autre caractéristique de l'invention, le diamètre de l'élément tubulaire précité est sensiblement égal au diamètre de l'orifice précité formant siège que peut traverser le pinceau dont le diamètre est très voisin de celui dudit orifice formant siège.According to yet another characteristic of the invention, the diameter of the above-mentioned tubular element is substantially equal to the diameter of the aforementioned orifice forming a seat which the brush can pass through, the diameter of which is very close to that of said orifice forming a seat.
Ainsi, lors du dévissage du bouchon provoquant la pénétration du fourreau dans le corps et donc le dégagement du pinceau du fourreau, on évite avantageusement une sortie incontrôlée du produit contenu dans le réservoir et qui ainsi ne risque pas de s'échapper lors de l'appareil applicateur.Thus, during the unscrewing of the cap causing the penetration of the sheath into the body and therefore the release of the brush from the sheath, it is advantageous to avoid an uncontrolled exit of the product contained in the reservoir and which thus does not risk escaping during the applicator device.
Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels.However, other characteristics and advantages of the invention will appear better in the detailed description which follows and which refers to the appended drawings, given solely by way of example, and in which.
La figure 1 est une vue en coupe axiale et partielle (réservoir illustré partiellement) du dispositif applicateur représenté en position prête à l'utilisation. La figure 2 est une vue similaire à la figure 1 mais sur laquelle le bouton-poussoir est actionné pour délivrer du produit liquide, tel que vernis à ongle, au pinceau applicateur.Figure 1 is an axial and partial sectional view (tank shown partially) of the applicator device shown in the ready-to-use position. Figure 2 is a view similar to Figure 1 but on which the push button is actuated to deliver liquid product, such as nail polish, to the applicator brush.
La figure 3 est une vue similaire aux figures précédentes, mais montrant le dispositif en début d'obturation au moyen d'un bouchon ou capuchon selon 1'invention.Figure 3 is a view similar to the previous figures, but showing the device at the start of obturation by means of a plug or cap according to the invention.
La figure 4 est une vue identique à la figure 3, mais montrant le bouchon ou capuchon en position finale d'obturation du récipient.Figure 4 is a view identical to Figure 3, but showing the plug or cap in the final closed position of the container.
La figure 5 est une vue en coupe axiale d'une variante de capuchon.Figure 5 is an axial sectional view of an alternative cap.
En se reportant notamment aux figures 3 et 4, on voit qu'un dispositif conforme à cette invention comprend essentiellement un bouchon 1 susceptible d'obturer le corps 2 d'un appareil applicateur qui comporte un réservoir R en communication permanente, comme montré par la flèche F, avec un fourreau 3 monté coulissant dans le corps 2 et susceptible de coopérer avec le bouchon ou capuchon 1.With particular reference to FIGS. 3 and 4, it can be seen that a device according to this invention essentially comprises a plug 1 capable of closing off the body 2 of an applicator device which comprises a reservoir R in permanent communication, as shown by the arrow F, with a sleeve 3 slidably mounted in the body 2 and capable of cooperating with the plug or cap 1.
Suivant l'exemple de réalisation représenté sur les figures 3 à 5, le capuchon 1 comporte deux parois tubulaires concentriques, à savoir une paroi ou enveloppe tubulaire externe 4, et une paroi tubulaire interne 5 comportant un filetage 5a extérieur ou faisant face à la paroi 4.According to the embodiment shown in Figures 3 to 5, the cap 1 comprises two concentric tubular walls, namely an outer tubular wall or casing 4, and an inner tubular wall 5 having an external thread 5a or facing the wall 4.
Ainsi, grâce à la configuration spéciale du capuchon 1 avec filetage 5a isolé entre les deux parois tubulaires 4, 5, on évite avantageusement toute souillure éventuelle de ce filetage par le produit du réservoir, et donc tout risque possible de grippage du capuchon sur l'appareil. Un tel avantage est particulièrement appréciable dans le cas où le produit contenu dans le réservoir serait du vernis à ongle.Thus, thanks to the special configuration of the cap 1 with isolated thread 5a between the two tubular walls 4, 5, any possible contamination is advantageously avoided. of this thread by the product from the tank, and therefore any possible risk of the cap seizing on the device. Such an advantage is particularly appreciable in the case where the product contained in the reservoir is nail varnish.
Le fourreau mobile 3 suivant l'exemple représenté, comporte lui aussi deux parois tubulaires concentriques, à savoir d'une part une paroi tubulaire externe 6 portant un filetage intérieur 6a et pouvant s'insérer dans l'espace entre les parois tubulaires 4 et 5 du capuchon 1 de manière que le filetage 6a vienne en prise avec le filetage 5a, et d'autre part une paroi tubulaire interne 7 susceptible de trouver place à l'intérieur du bouchon 1 dans un logement 8, ce logement étant défini par la paroi tubulaire interne et filetée 5 dudit bouchon, comme on le voit bien sur les figures 3 et 4.The movable sheath 3 according to the example shown, also comprises two concentric tubular walls, namely on the one hand an external tubular wall 6 carrying an internal thread 6a and which can be inserted in the space between the tubular walls 4 and 5 of the cap 1 so that the thread 6a comes into engagement with the thread 5a, and on the other hand an internal tubular wall 7 capable of finding a place inside the plug 1 in a housing 8, this housing being defined by the wall internal and threaded tubular 5 of said plug, as can be seen in FIGS. 3 and 4.
On pourrait parfaitement, sans sortir du cadre de l'invention, prévoir pour le fourreau 3 une paroi tubulaire unique et extérieurement filetée coopérant avec une paroi tubulaire intérieurement filetée et elle aussi unique du bouchon ou capuchon 1.One could perfectly, without departing from the scope of the invention, provide for the sheath 3 a single tubular wall and externally threaded cooperating with a tubular wall internally threaded and also unique of the plug or cap 1.
Le fourreau 3 est monté coulissant sans rotation dans le corps 2, et à cet effet, il comporte un ergot ou analogue 8a coopérant avec une rainure ou autre moyen analogue 29 prévu sur la périphérie interne du corps 2. Le fourreau 3 comporte une partie d'extrémité 3a montée à coulissement étanche sur un élément tubulaire 9 solidaire du corps 2 et prolongeant en quelque sorte le réservoir R, de sorte que le fourreau 3 est en communication permanente avec ledit réservoir. On a montré en 10 un anneau élastique ou analogue serrant de façon étanche la partie d'extrémité 3a du fourreau 3 tout en permettant le coulissement dudit fourreau le long du prolongement tubulaire 9. Le fourreau 3 comporte une extrémité opposée 3b munie d'un orifice 11 formant siège pour un clapet 12 équipé d'un pinceau applicateur 13 pouvant passer au travers de l'orifice 11.The sleeve 3 is mounted sliding without rotation in the body 2, and for this purpose, it comprises a lug or the like 8a cooperating with a groove or other similar means 29 provided on the internal periphery of the body 2. The sleeve 3 comprises a part d 'end 3a mounted in leaktight sliding on a tubular element 9 integral with the body 2 and extending in a way the tank R, so that the sheath 3 is in permanent communication with said tank. An elastic ring or the like has been shown at 10 tightly sealing the end portion 3a of the sleeve 3 while allowing said sleeve to slide along the extension tubular 9. The sheath 3 has an opposite end 3b provided with an orifice 11 forming a seat for a valve 12 equipped with an applicator brush 13 which can pass through the orifice 11.
La pièce 12 formant clapet est logée à l'intérieur du fourreau mobile 3 et est solidaire du corps 2 du récipient par l'intermédiaire d'une tige ou autre moyen analogue 14. On voit que cette tige est fixée en 15 sur une partie du corps 2 du récipient et est située sensiblement sur l'axe du prolongement tubulaire 9 et du fourreau 3. Ainsi, la position du clapet 12 et donc du pinceau applicateur 13 dans le corps 2 du récipient est fixe, et c'est, comme on le verra plus loin, le fourreau 3 qui se déplace par rapport à ce clapet lors du vissage ou du dévissage du capuchon 1 pour mettre hors service ou en service le pinceau applicateur 13.The part 12 forming a valve is housed inside the movable sheath 3 and is integral with the body 2 of the container by means of a rod or other similar means 14. It can be seen that this rod is fixed at 15 to part of the body 2 of the container and is located substantially on the axis of the tubular extension 9 and of the sleeve 3. Thus, the position of the valve 12 and therefore of the applicator brush 13 in the body 2 of the container is fixed, and this is, as we as will be seen below, the sheath 3 which moves relative to this valve during the screwing or unscrewing of the cap 1 to put the applicator brush 13 out of service or in service.
On a montré en 16 un ressort agencé entre le clapet 12 et le fond du fourreau 3 constitué par sa partie d'extrémité 3a. Ce ressort 16 sollicite constamment le fourreau 3 en direction du réservoir R, c'est-à-dire sollicite constamment l'orifice formant siège 11 en position appliquée contre le clapet 12, position pour laquelle le pinceau applicateur 13 fait saillie de l'orifice 11, comme on le décrira plus loin à propos du fonctionnement.16 shows a spring arranged between the valve 12 and the bottom of the sleeve 3 constituted by its end part 3a. This spring 16 constantly urges the sheath 3 towards the reservoir R, that is to say constantly urges the orifice forming seat 11 in the position applied against the valve 12, position for which the applicator brush 13 protrudes from the orifice 11, as will be described later in connection with the operation.
Sur le corps 2 est monté un bouton-poussoir 17 faisant saillie dudit corps et muni d'une lame-ressort 18 dont une extrémité 18a est solidaire du corps 2 et dont l'autre extrémité 18b peut actionner le fourreau 3 sous l'effet d'une pression appliquée sur ledit bouton- poussoir 17, comme on l'expliquera en détail plus loin. On observera que le réservoir R, représenté partiellement sur les figures, peut être raccordé de façon amovible ou non, par tout moyen approprié, au corps 2. Egalement, sans sortir du cadre de l'invention, ce réservoir R pourrait être intégral au corps 2, c'est-à-dire constituer une partie de ce corps.On the body 2 is mounted a push button 17 projecting from said body and provided with a leaf spring 18, one end 18a of which is secured to the body 2 and the other end of which 18b can actuate the sheath 3 under the effect of 'A pressure applied to said push button 17, as will be explained in detail below. It will be observed that the tank R, shown partially in the figures, can be connected removably or not, by any suitable means, to the body 2. Also, without departing from the scope of the invention, this tank R could be integral with the body 2, that is to say constitute a part of this body.
Suivant la variante représentée sur la figure 5, le bouchon 1 est intérieurement muni d'un ressort 19 qui retient une bague 20 pouvant coulisser dans le logement 8 précédemment mentionné et défini par la paroi tubulaire interne et filetée 5 du bouchon.According to the variant shown in Figure 5, the plug 1 is internally provided with a spring 19 which retains a ring 20 which can slide in the housing 8 previously mentioned and defined by the internal tubular and threaded wall 5 of the plug.
Cette bague 20 permet de réaliser l'étanchéité au niveau de l'extrémité 3b du fourreau 3 dès qu'on commence le vissage du bouchon 1 sur le corps 2.This ring 20 makes it possible to seal at the end 3b of the sleeve 3 as soon as the plug 1 is screwed onto the body 2.
Mais, pour une meilleure compréhension de l'invention, on expliquera ci-après le fonctionnement du dispositif selon cette invention en se reportant successivement aux figures 1 à 5.However, for a better understanding of the invention, the operation of the device according to this invention will be explained below, referring successively to FIGS. 1 to 5.
Lorsque le bouchon ou capuchon 1 est enlevé, comme on le voit sur la figure 1, le ressort 16 sollicite le fourreau 3 en direction du réservoir R, de sorte que l'orifice 11 est obturé par le clapet 12 portant le pinceau applicateur 13 qui fait saillie dudit orifice. Dans cette position, l'extrémité 18b de la lame-ressort 18 du bouton-poussoir 17 prend appui sur le fourreau 3, ou plus précisément sur un épaulement 3c que forme ce fourreau au niveau de l'ergot 8a.When the plug or cap 1 is removed, as can be seen in FIG. 1, the spring 16 biases the sheath 3 in the direction of the reservoir R, so that the orifice 11 is closed by the valve 12 carrying the applicator brush 13 which protrudes from said orifice. In this position, the end 18b of the leaf spring 18 of the push button 17 bears on the sheath 3, or more precisely on a shoulder 3c that this sheath forms at the lug 8a.
Par conséquent, comme on le voit sur la figure 2, en exerçant une pression avec le doigt sur le bouton-poussoir 17, le fourreau 3 sera poussé à l'encontre de la force exercée par le ressort 16, de sorte que l'orifice 11 du fourreau se dégagera du clapet 12 et permettra au liquide contenu dans le réservoir R d'imbiber le pinceau applicateur 13 au niveau de sa partie située à l'intérieur du fourreau 3. Autrement dit, l'utilisateur ou l'utilisatrice pourra, en cours d'utilisation et à volonté, appeler du liquide contenu dans le réservoir R en comprimant plus ou moins le bouton-poussoir 17 vers l'axe de l'appareil. Cette faculté de pouvoir doser l'imprégnation du pinceau avec le produit exactement en fonction des besoins de l'utilisateur, constitue un avantage incontestable sur de nombreux applicateurs connus qui ne délivrent du produit qu'en continu ou suivant des quantités non dosables risquant ainsi de procurer un écoulement excessif indésirable.Consequently, as can be seen in FIG. 2, by exerting a pressure with the finger on the push button 17, the sheath 3 will be pushed against the force exerted by the spring 16, by so that the orifice 11 of the sheath will disengage from the valve 12 and allow the liquid contained in the reservoir R to soak the applicator brush 13 at its part located inside the sheath 3. In other words, the user or the user can, during use and at will, call the liquid contained in the reservoir R by compressing more or less the push button 17 towards the axis of the device. This ability to be able to dose the impregnation of the brush with the product exactly according to the needs of the user, constitutes an undeniable advantage over many known applicators which deliver the product only continuously or in non-dosable quantities thus risking provide unwanted excessive flow.
En fin d'utilisation, comme on le voit sur la figure 3, on pourra visser le bouchon ou capuchon 1 par sa partie tubulaire interne et filetée 5 sur le fourreau 3, c'est-à-dire plus précisément sur la partie tubulaire externe et filetée 6 de ce fourreau. Lors du vissage, la partie tubulaire externe 4 du capuchon 1 prendra appui sur l'extrémité 2a du corps 2 de l'appareil. Ainsi, le fourreau 3 sera attiré, par vissage, vers l'intérieur du capuchon 1, alors que le clapet 12 demeurera immobile, puisqu'il est fixé par la tige 14 sur le corps 2. Dès lors, au fur et à mesure du vissage du capuchon 1, et donc de 1'éloignement progressif de l'orifice 11 du clapet fixe 12, le pinceau applicateur 13 viendra progressivement se loger dans le fourreau 3, et cela tout en lissant les poils ou fibres du pinceau 13 sur le bord de l'orifice 11.At the end of use, as can be seen in FIG. 3, the plug or cap 1 can be screwed by its internal tubular and threaded part 5 on the sheath 3, that is to say more precisely on the external tubular part and threaded 6 of this sheath. During the screwing, the external tubular part 4 of the cap 1 will bear on the end 2a of the body 2 of the device. Thus, the sleeve 3 will be attracted, by screwing, towards the inside of the cap 1, while the valve 12 will remain immobile, since it is fixed by the rod 14 on the body 2. Consequently, as the screwing the cap 1, and therefore from the gradual moving away from the orifice 11 of the fixed valve 12, the applicator brush 13 will gradually come to be housed in the sheath 3, and this while smoothing the bristles or fibers of the brush 13 on the edge orifice 11.
On observera qu'avec le bouchon des figures 3 et 4, les extrémités libres des parois tubulaires 4, 5 sont situés dans des plans très proches l'un de l'autre, de sorte que l'obturation du corps 2 est réalisée immédiatement par appui de l'extrémité libre de la paroi 4 sur l'extrémité 2a du corps 2, et ceci avant le début du vissage.It will be observed that with the plug of FIGS. 3 and 4, the free ends of the tubular walls 4, 5 are located in planes very close to each other, so that the body 2 is closed immediately by pressing the free end of the wall 4 on the end 2a of the body 2, and this before the start of screwing.
Il est encore important de remarquer ici que la mise en place et le vissage du capuchon 1 ne pourront en aucun cas endommager le pinceau applicateur 13 qui, en quelque sorte, se retirera dans le fourreau 3 au fur et à mesure du vissage du capuchon.It is also important to note here that the installation and screwing of the cap 1 can in no case damage the applicator brush 13 which, in a way, will withdraw into the sheath 3 as the cap is screwed.
En fin de vissage du capuchon 1, et comme on le voit bien sur la figure 4, le ressort de rappel 16 est comprimé, le pinceau applicateur est complètement escamoté à 1'intérieur du fourreau 3 et le fond du capuchon 1 vient obturer l'orifice 11.At the end of screwing on the cap 1, and as can be seen in FIG. 4, the return spring 16 is compressed, the applicator brush is completely retracted inside the sheath 3 and the bottom of the cap 1 closes the port 11.
Il est à noter que, dans cette position, d'une part le pinceau applicateur 13 demeure en contact avec le liquide ou les vapeurs de celui-ci, contenu dans le réservoir R, Q ce qui évite avantageusement tout séchage possible du pinceau en cas de non utilisation, et d'autre part, la lame-ressort 18 du bouton-poussoir 17 ne peut plus actionner le fourreau 3 par son extrémité 18b, même en cas de pression accidentelle sur ledit bouton-poussoir. 5It should be noted that, in this position, on the one hand the applicator brush 13 remains in contact with the liquid or the vapors thereof, contained in the reservoir R, Q which advantageously avoids any possible drying of the brush in the event of non-use, and on the other hand, the leaf spring 18 of the push button 17 can no longer actuate the sheath 3 by its end 18b, even in the event of accidental pressure on said push button. 5
Bien entendu, pour remettre le dispositif en position de service à partir de la position fermée visible sur la figure 4, il suffira d'effectuer les opérations inverses de celles décrites ci-dessus, c'est-à-dire de dévisser le 0 capuchon 1, ce qui, sous l'effet du ressort 16, provoquera le retrait du fourreau 3 dans le corps 2, jusqu'à ce que l'orifice formant siège 11 du fourreau 3 vienne en appui sur le clapet 12, comme montré sur la figure 1. Le fonctionnement qui vient d'être décrit sera exactement le même avec la variante de capuchon illustrée sur la figure 5, à cela près qu'ici, dès le début du vissage du bouchon pour obturer le récipient, la bague 20 prendra élastiquement appui sur l'extrémité 3b du fourreau 3, de façon que le liquide contenu dans l'appareil ne puisse pas s'échapper lors de l'ouverture de l'orifice 11 provoquée par le vissage du bouchon. Bien entendu, comme expliqué plus haut, l'extrémité libre de la paroi tubulaire 4 du bouchon prendra appui également dès le début du vissage sur l'extrémité 2a du corps 2 pour réaliser ainsi son obturation et constituer une sécurité supplémentaire à l'échappement du produit.Of course, to return the device to the service position from the closed position visible in FIG. 4, it will suffice to carry out the reverse operations to those described above, that is to say to unscrew the 0 cap. 1, which, under the effect of the spring 16, will cause the withdrawal of the sheath 3 in the body 2, until the seat orifice 11 of the sheath 3 comes to bear on the valve 12, as shown on the figure 1. The operation which has just been described will be exactly the same with the variant of cap illustrated in FIG. 5, except that here, from the start of the screwing of the cap to close the container, the ring 20 will take elastic rest on the end 3b of the sleeve 3, so that the liquid contained in the device cannot escape during the opening of the orifice 11 caused by the screwing of the plug. Of course, as explained above, the free end of the tubular wall 4 of the stopper will also bear from the start of the screwing on the end 2a of the body 2 so as to close it off and constitute additional security when escaping from the product.
On a donc réalisé suivant l'invention un dispositif d'obturation d'un appareil applicateur qui évite tout endommagement possible du pinceau applicateur à l'ouverture et à la fermeture de l'appareil, qui procure une sécurité à la délivrance accidentelle de produit lorsque le récipient est fermé, et qui évite tout assèchement du pinceau applicateur lorsque l'appareil est fermé puisque ledit pinceau baignera dans le liquide contenu dans le fourreau en communication permanente avec le réservoir.Therefore, according to the invention, a device for closing off an applicator device has been produced which avoids any possible damage to the applicator brush when the device is opened and closed, which provides security for the accidental delivery of product when the container is closed, and which prevents any drying out of the applicator brush when the device is closed since said brush will bathe in the liquid contained in the sheath in permanent communication with the reservoir.
Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiments described and illustrated which have been given only by way of example.
C'est ainsi que la matière constituant le corps du récipient et le bouchon peut être quelconque, que les formes coopérantes du bouchon et du fourreau peuvent être autres que celles représentées, et que les moyens d'actionnement du fourreau par le bouton-poussoir pourraient être autres qu'une lame-ressort. Egalement, le fourreau coopérant avec le bouchon pourrait être raccordé au réservoir d'une manière autre que celle représentée.Thus the material constituting the body of the container and the stopper may be any, that the cooperating forms of the stopper and of the sheath may be other than those shown, and that the means of actuation of the sheath by the push button could be other than a leaf spring. Also, the sheath cooperating with the plug could be connected to the tank in a manner other than that shown.
C'est dire que l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons, si celles-ci sont effectuées suivant son esprit. This means that the invention includes all the technical equivalents of the means described as well as their combinations, if these are carried out according to the spirit.
