Description

La présente invention concerne un réservoir de produit fluide comprenant un fond et un fût de coulissement, un piston étant monté à coulissement étanche dans le fût de coulissement. Des moyens de sollicitation élastique sont prévus pour pousser le piston dans le fût de coulissement de manière à réduire le volume utile du réservoir de produit fluide. Le réservoir comprend des moyens de maintien pour retenir le piston dans une position initiale à l'encontre des moyens de sollicitation élastique de sorte que le produit fluide stocké dans le réservoir n'est pas soumis à la pression du piston poussé par les moyens de sollicitation élastique. Le réservoir de produit fluide comprend en outre un organe de déblocage pour désactiver les moyens de maintien de sorte que les moyens de sollicitation élastique poussent alors le piston qui exerce une pression sur le produit fluide stocké dans le réservoir, cet organe de déblocage étant mobile entre une position initiale inopérante et une position finale opérante dans laquelle il agit sur les moyens de maintien pour les désactiver. Les domaines d'application privilégiés de la présente invention sont ceux de la cosmétique, de la pharmacie ou encore de la parfumerie.The present invention relates to a fluid reservoir comprising a bottom and a sliding shaft, a piston being slidably mounted in the sliding shaft. Elastic biasing means are provided for urging the piston into the slide shaft so as to reduce the useful volume of the fluid reservoir. The reservoir comprises holding means for retaining the piston in an initial position against the elastic biasing means so that the fluid product stored in the reservoir is not subjected to the pressure of the piston pushed by the biasing means elastic. The fluid reservoir further comprises an unlocking member for deactivating the holding means so that the elastic biasing means then push the piston which exerts pressure on the fluid stored in the reservoir, this unlocking member being movable between an inoperative initial position and an operative final position in which it acts on the holding means to deactivate them. The preferred fields of application of the present invention are those of cosmetics, pharmacy or even perfumery.

Dans l'art antérieur, on connaît le document US4223808 qui décrit un distributeur de produit fluide comprenant un tel réservoir sur lequel est monté un organe de distribution sous la forme d'une valve que l'on peut maintenir à l'état ouvert en appuyant sur un poussoir pourvu d'un gicleur. Le réservoir comprend un fût dans lequel coulisse un piston sous l'action d'un ressort. Le piston est pourvu de deux pattes souples munies de têtes d'accrochage qui sont en prises avec les bords de trous pratiqués dans une coupelle solidaire du fût. Le réservoir comprend également un fond mobile formant un dôme qui permet d'écarter les deux pattes souples pour les libérer de leurs bords respectifs. Lorsque le fond mobile est enfoncé à fond, les deux pattes souples sont libérées de la coupelle et le piston se déplace alors sous l'effet du ressort.In the prior art, the document is known US4223808 which describes a fluid dispenser comprising such a reservoir on which is mounted a dispensing member in the form of a valve that can be maintained in the open state by pressing a pusher provided with a nozzle. The reservoir comprises a barrel in which a piston slides under the action of a spring. The piston is provided with two flexible lugs provided with hooking heads which are engaged with the edges of holes made in a cup integral with the barrel. The reservoir also includes a movable bottom forming a dome which allows to separate the two flexible tabs to release them from their respective edges. When the movable bottom is fully pressed, the two flexible tabs are released from the cup and the piston then moves under the effect of the spring.

Dans ce réservoir de l'art antérieur, une partie visible, à savoir le fond mobile, est déplacé d'une position initiale vers une position finale de libération des pattes souples. Le déplacement du fond mobile modifie ainsi l'aspect extérieur du réservoir, ce qui nuit bien entendu à son esthétique d'ensemble. En effet, il n'est jamais heureux de pourvoir un réservoir visible, et donc esthétique, d'une pièce fonctionnelle.In this tank of the prior art, a visible part, namely the moving bottom, is moved from an initial position to a final position of release of the flexible tabs. Moving the movable bottom and changes the appearance of the tank, which of course affects its overall aesthetics. Indeed, he is never happy to provide a visible tank, and therefore aesthetic, a functional room.

Dans l'art antérieur, on connaît également les documents DE202007002677 , CH465157 , US1303845 et US3377003 qui décrivent tous des organes de déblocage qui fond saillie vers le bas au niveau du fond du réservoir. L'utilisateur doit les manipuler (pousser ver le haut - tourner - presser - basculer, etc.) pour faire passer l'organe de déblocage à travers un trou formé dans le fond du réservoir. Par conséquent, ces organes de déblocage sont visibles avant utilisation et nuisent à l'esthétique du réservoir et du distributeur.In the prior art, the documents are also known DE202007002677 , CH465157 , US1303845 and US3377003 all of which disclose unlocking members which merge downwardly at the bottom of the tank. The user must manipulate them (push up - turn - press - toggle, etc.) to pass the release member through a hole in the bottom of the tank. Therefore, these unlocking members are visible before use and adversely affect the aesthetics of the reservoir and the dispenser.

L'invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un réservoir de produit fluide dont l'organe de déblocage peut être manipulé de manière plus discrète, sans nuire et sans modifier l'aspect esthétique du réservoir. Un autre but de la présente invention est de rendre quasiment invisible l'organe de déblocage. Un autre but de la présente invention est d'informer l'utilisateur de la première utilisation du réservoir tout en masquant l'organe de déblocage.The invention aims to overcome the aforementioned drawbacks of the prior art by defining a fluid reservoir whose unlocking member can be handled in a more discrete manner, without harming and without modifying the aesthetic appearance of the reservoir. Another object of the present invention is to make almost invisible the unlocking member. Another object of the present invention is to inform the user of the first use of the reservoir while masking the unlocking member.

Pour ce faire, la présente invention propose que l'organe de déblocage soit accessible, pour le déplacer manuellement de la position initiale inopérante vers la position finale opérante, à travers une ouverture d'accès formée au niveau du fond du réservoir de produit fluide. Contrairement au document US4223808 , le fond n'est pas mobile, mais au contraire parfaitement fixe, de sorte que le réservoir peut globalement être réalisé de manière monobloc au niveau de sa paroi externe visible. Contrairement aux quatre autres documents précités, l'organe de déblocage est entièrement disposé du côté interne de l'ouverture d'accès, de sorte que l'utilisateur doit introduire son doigt ou un autre objet à travers l'ouverture d'accès pour atteindre et actionner l'organe de déblocage, qui est pour ainsi dire cacher à l'intérieur du réservoir.To do this, the present invention proposes that the unlocking member is accessible to move it manually from the inoperative initial position to the operative final position, through an access opening formed at the bottom of the fluid reservoir. Unlike the document US4223808 , the bottom is not mobile, but on the contrary perfectly fixed, so that the tank can be made integrally in one piece at its visible outer wall. Unlike the other four aforementioned documents, the unlocking member is entirely disposed on the inner side of the access opening, so that the user must introduce his finger or another object through the opening. access to reach and operate the unlocking member, which is virtually hidden inside the tank.

Selon une caractéristique avantageuse de l'invention, l'ouverture d'accès peut présenter une taille légèrement supérieure à la section d'un doigt pour qu'un utilisateur puisse insérer son doigt à travers l'ouverture d'accès et pousser l'organe de déblocage dans sa position initiale inopérante pour qu'il atteigne sa position finale opérante.According to an advantageous characteristic of the invention, the access opening may have a size slightly greater than the section of a finger so that a user can insert his finger through the access opening and push the organ in its initial inoperative position so that it reaches its operative final position.

Selon une autre caractéristique avantageuse de l'invention, l'ouverture d'accès est initialement recouverte par une étiquette de premier usage qui masque l'ouverture d'accès. On peut par exemple se servir de cette étiquette de premier usage pour l'apposition d'instructions permettant de faire comprendre à l'utilisateur le mode d'emploi du réservoir. On peut par exemple inscrire sur l'étiquette « retirez puis appuyez ». Etant donné que la section de l'ouverture d'accès est réduite, on peut utiliser une petite étiquette de premier usage qui adhère au bord extérieur de l'ouverture d'accès.According to another advantageous characteristic of the invention, the access opening is initially covered by a first-use label which conceals the access opening. For example, it is possible to use this first-use label for affixing instructions making it possible to make the user understand the instructions for use of the reservoir. For example, you can write on the label "remove and then press". Since the section of the access opening is small, a small first-use label that adheres to the outer edge of the access opening can be used.

Selon un autre aspect intéressant de la présente invention, l'organe de déblocage peut comprendre une face d'appui qui affleure l'ouverture d'accès de manière à compléter le fond du réservoir. Dans ce cas, l'ouverture d'accès est à peine visible puisqu'elle est parfaitement comblée par l'organe de déblocage dont la face d'appui est alignée avec la paroi extérieure du fond du réservoir. La face d'appui peut être visible, et dans ce cas comprendre une instruction du type « appuyez » ou « push ». Il est également possible de recouvrir la face d'appui avec une étiquette de premier usage qui va parfaitement masquer l'organe de déblocage, étant donné que sa face d'appui est affleurante avec l'ouverture d'accès.According to another advantageous aspect of the present invention, the unlocking member may comprise a bearing face which is flush with the access opening so as to complete the bottom of the tank. In this case, the access opening is barely visible since it is perfectly filled by the release member whose bearing face is aligned with the outer wall of the tank bottom. The bearing face may be visible, and in this case include a "push" or "push" type instruction. It is also possible to cover the bearing face with a first-use label that will perfectly hide the unlocking member, since its bearing face is flush with the access opening.

L'étiquette de premier usage et/ou la face d'appui affleurante permettent de rendre quasiment invisible ou imperceptible la présence d'un organe de déblocage. De ce fait, l'apparence esthétique du réservoir est parfaitement préservée.The label of first use and / or the flush abutment face make it almost invisible or imperceptible the presence of an unlocking member. As a result, the aesthetic appearance of the tank is perfectly preserved.

Selon une forme de réalisation pratique, les moyens de maintien peuvent comprendre plusieurs pattes souples dotées de têtes d'accrochage en prise, en position initiale inopérante, avec un profil d'accrochage correspondant solidaire du piston, l'organe de déblocage, déplacé de sa position initiale inopérante jusqu'à sa position finale opérante, déformant élastiquement les pattes souples pour désengager les têtes d'accrochage de leur profil d'accrochage correspondant, libérant ainsi le piston.According to a practical embodiment, the holding means may comprise a plurality of flexible tabs with gripping heads in engagement, in inoperative initial position, with a hooking profile. corresponding integral piston, the unlocking member, moved from its initial inoperative position to its operative final position, elastically deforming the flexible tabs to disengage the fastening heads of their corresponding latching profile, thus releasing the piston.

Selon un autre aspect avantageux de l'invention, le réservoir peut comprendre une coque externe définissant le fond au niveau de laquelle est formée l'ouverture d'accès. Avantageusement, l'organe de déblocage repose, en position initiale inopérante, contre un bord interne de l'ouverture d'accès. Ainsi, il est aisé de positionner la face d'appui de manière affleurante avec la paroi externe de l'ouverture d'accès.According to another advantageous aspect of the invention, the reservoir may comprise an outer shell defining the bottom at which the access opening is formed. Advantageously, the unlocking member rests, in an inoperative initial position, against an inner edge of the access opening. Thus, it is easy to position the support face flush with the outer wall of the access opening.

Selon une autre caractéristique avantageuse de l'invention, le réservoir peut comprendre un godet interne reçu à l'intérieur de la coque externe, le godet interne formant le fût de coulissement et une partie des moyens de maintien. Selon une forme de réalisation pratique, le godet interne forme une douille de guidage pour guider l'organe de déblocage lors de son déplacement de sa position initiale inopérante vers sa position finale opérante. De préférence, l'organe de déblocage comprend une couronne de support et de guidage qui repose sur le bord interne de l'ouverture d'accès en position initiale inopérante et qui coulisse dans douille de guidage quand l'organe de déblocage est poussé vers position finale opérante, l'organe de déblocage comprenant en outre un pointeau d'écartement engagé entre les pattes souples pour les contraindre vers l'extérieur lorsqu'il est en position finale opérante. Avantageusement, l'organe de déblocage est retenu, avantageusement par encliquetage, dans les pattes souples en position finale opérante. La couronne de support et de guidage peut également venir en butée contre une paroi du godet interne en position finale opérante.According to another advantageous characteristic of the invention, the reservoir may comprise an internal cup received inside the outer shell, the inner cup forming the sliding drum and a part of the holding means. According to a practical embodiment, the inner cup forms a guide sleeve for guiding the unlocking member during its displacement from its inoperative initial position to its operative final position. Preferably, the release member comprises a support and guide ring which rests on the inner edge of the access opening inoperative inoperative position and which slides in guide bush when the unlocking member is pushed towards position. operant final, the unlocking member further comprising a spacer needle engaged between the flexible tabs to constrain outwardly when it is in the final operative position. Advantageously, the unlocking member is retained, advantageously by snapping, into the flexible tabs in operative final position. The support and guide ring can also abut against a wall of the inner cup in operative final position.

L'esprit de l'invention repose sur le fait de rendre le plus discret possible l'organe de déblocage en préservant au maximum l'esthétique du réservoir. L'étiquette de premier usage et la face d'appui affleurante sont deux caractéristiques, qui peuvent être mises en oeuvre individuellement ou cumulativement, et qui participent activement à la discrétion de l'organe de déblocage. La taille de l'ouverture d'accès permet également de rendre l'organe de déblocage plus discret.The spirit of the invention is based on the fact of making the most discreet possible release member preserving the maximum aesthetics of the tank. The first use label and the flush abutment face are two features that can be implemented individually or cumulatively and that actively participate at the discretion of the release. The size of the access opening also makes the release member more discreet.

L'invention sera maintenant décrite plus en détail en référence aux dessins joints, donnant à titre d'exemple non limitatif, un mode de réalisation de l'invention.The invention will now be described in more detail with reference to the accompanying drawings, giving by way of non-limiting example, an embodiment of the invention.

L'organe de distribution peut par exemple se présenter sous la forme d'un couvercle rapporté sur le réservoir et intégrant un clapet de sortie que l'utilisateur peut actionner à l'aide d'un doigt. A la place du clapet, on peut également utiliser une valve ou encore une pompe. L'organe de distribution n'est pas représenté sur les figures, car il n'est pas critique pour la présente invention. En d'autres termes, le réservoir de produit fluide de la présente invention peut recevoir n'importe quel type d'organe de distribution approprié.The fluid reservoir of the present invention is intended to be associated with a fluid dispenser member which closes the reservoir and allows fluid dispensing therethrough. The dispenser member may for example be in the form of a lid attached to the reservoir and incorporating an outlet valve that the user can actuate with a finger. Instead of the valve, one can also use a valve or a pump. The dispenser member is not shown in the figures because it is not critical to the present invention. In other words, the fluid reservoir of the present invention can accommodate any type of suitable dispensing member.

Le réservoir de produit fluide utilisé pour illustrer la présente invention comprend plusieurs pièces distinctes, à savoir une coque externe 1, un organe de déblocage 3, un godet interne 4, un ressort 5 et un piston 6. Le réservoir peut également comprendre de manière optionnelle une étiquette de premier usage 2. Toutes ces pièces sont clairement visibles sur la figure 3.The fluid reservoir used to illustrate the present invention comprises several distinct parts, namely an outer shell 1, an unlocking member 3, an inner cup 4, a spring 5 and a piston 6. The reservoir may also optionally comprise a label of first use 2. All these parts are clearly visible on the figure 3 .

La coque externe 1 est de préférence réalisée de manière monobloc par injection moulage de matière plastique appropriée. On peut par exemple utiliser une matière plastique transparente pour conférer un effet esthétique particulier. La coque externe 1 comprend un fond 11 percé d'une ouverture d'accès 13 définissant un bord annulaire interne 12i et un bord annulaire externe 12e. La tranche de l'ouverture d'accès 13 est de préférence réduite. On peut par exemple remarquer sur les figures que l'épaisseur de paroi du fond 11 diminue vers l'ouverture d'accès 13. La taille de l'ouverture d'accès 13 est de préférence légèrement supérieure à la section moyenne d'un doigt, par exemple l'index, pour qu'un utilisateur puisse insérer son doigt à travers l'ouverture d'accès sans y rester coincé.The outer shell 1 is preferably made integrally by injection molding of suitable plastic material. For example, it is possible to use a transparent plastic material to confer a particular aesthetic effect. The outer shell 1 comprises a bottom 11 pierced with an opening 13 defining an inner annular edge 12i and an outer annular edge 12e. The portion of the access opening 13 is preferably reduced. It can be seen for example in the figures that the wall thickness of the bottom 11 decreases towards the access opening 13. The size of the access opening 13 is preferably slightly greater than the average section of a finger , for example the index, so that a user can insert his finger through the access opening without being stuck.

La coque externe 1 comprend également un corps périphérique 14 qui s'étend vers le haut à partir du bord externe du fond 11. Le corps 14 peut être cylindrique, ou au contraire présenter une forme quelconque. L'extrémité supérieure du corps 14 forme un col 15, qui est avantageusement pourvu de profils d'accrochage, par exemple sous la forme d'un filetage. Ce profil d'accrochage va servir à la fixation d'un organe de distribution qui vient compléter le réservoir pour former un distributeur de produit fluide.The outer shell 1 also comprises a peripheral body 14 which extends upwardly from the outer edge of the bottom 11. The body 14 may be cylindrical, or otherwise have any shape. The upper end of the body 14 forms a neck 15, which is advantageously provided with hooking profiles, for example in the form of a thread. This hooking profile will serve to fix a dispensing member that completes the reservoir to form a fluid dispenser.

L'étiquette de premier usage 2 comprend une pastille adhésive 21 dont le diamètre est supérieur à celui de l'ouverture d'accès 13, de sorte que la pastille 21 peut venir en contact adhésif avec le bord extérieur 12e de l'ouverture d'accès 13. Ainsi, la pastille 21 masque entièrement et parfaitement l'ouverture d'accès 13. L'étiquette de premier usage 2 peut également comprendre une languette de préhension 22 par laquelle l'utilisateur peut saisir l'étiquette 2 pour la retirer du fond 11 de la coque externe 1. La face visible de la pastille 21 peut comprendre toute indication, marque, logo ou mode d'emploi. On peut par exemple apposer l'inscription « retirez puis appuyez » ou encore « tear off and push ».The first-use label 2 comprises an adhesive pellet 21 whose diameter is greater than that of the access opening 13, so that the pellet 21 can come into adhesive contact with the outer edge 12 of the opening of access 13. Thus, the tablet 21 fully and completely masks the access opening 13. The first-use label 2 may also include a gripping tab 22 by which the user can enter the label 2 to remove it from the bottom 11 of the outer shell 1. The visible face of the pellet 21 may include any indication, mark, logo or instructions for use. For example, you can write "remove and then press" or "tear off and push".

L'organe de déblocage 3 se présente globalement sous la forme d'un petit pion comprenant un pointeau d'écartement 31 qui fait saillie à partir d'une face d'appui 32. Le pointeau d'écartement 31 est ici représenté avec une configuration creuse mais il pourrait également être plein. La face d'appui 32 présente un diamètre supérieur à celui du pointeau 31 et définit sur sa périphérie extérieure une couronne de support et de guidage 33 qui définit également un rebord annulaire 34 orienté vers le bas, et disposé en décalage par rapport à la face d'appui 32.The release member 3 is generally in the form of a small pin comprising a spacer 31 which protrudes from a bearing face 32. The spacer needle 31 is here shown with a configuration hollow but it could also be full. The bearing face 32 has a diameter greater than that of the needle 31 and defines on its outer periphery a support and guide ring 33 which also defines an annular flange 34 oriented downwards, and disposed offset from the face of support 32.

Le godet interne 4 comprend une paroi de fond 41 qui est pourvue en son centre d'un appendice complexe qui fait saillie vers le haut. Cet appendice complexe comprend de l'extérieur vers l'intérieur une douille de guidage cylindrique 42 qui se prolonge vers l'intérieur par une bride annulaire 43 qui se prolonge elle-même sur sa périphérie interne par plusieurs pattes souples 44 dont les extrémités supérieures libres sont formées avec des têtes d'accrochage 45 qui font saillie vers l'intérieur. Les pattes 44 sont inclinées vers l'intérieur pour former toutes ensemble un tronçon tronconique interrompu par des fentes axiales verticales qui séparent les pattes. Du fait de leur élasticité, les pattes 44 peuvent être déformées vers l'extérieur de manière à agrandir les fentes en forme de triangle. La paroi de fond 41 se prolonge également sur sa périphérie externe pour former un corps de godet 46 définissant intérieurement un fût de coulissement 47, qui présente une forme cylindrique, avantageusement circulaire. L'extrémité supérieure du corps de godet 46 forme une collerette d'appui 48 qui fait saillie radialement vers l'extérieur.The inner cup 4 comprises a bottom wall 41 which is provided at its center with a complex appendage projecting upwards. This complex appendage comprises, from the outside towards the inside, a cylindrical guide bush 42 which extends inwards through an annular flange 43 which itself extends on its inner periphery by a plurality of flexible tabs 44 whose free upper ends are formed with hooking heads 45 which project inwards. The tabs 44 are inclined inwardly to form together a frustoconical section interrupted by vertical axial slots which separate the tabs. Due to their elasticity, the tabs 44 may be deformed outwardly so as to enlarge the triangle-shaped slots. The bottom wall 41 also extends on its outer periphery to form a cup body 46 internally defining a sliding shaft 47, which has a cylindrical shape, preferably circular. The upper end of the cup body 46 forms a bearing flange 48 which protrudes radially outwardly.

Le ressort 5 peut être de toute nature et de toute forme, dans la mesure où il permet de remplir sa fonction de poussée. Dans le mode de réalisation utilisé pour illustrer la présente invention, le ressort 5 présente plusieurs caractéristiques avantageuses, et notamment sa forme en spirale concentrique, sa réalisation en matière plastique, sa section rectangulaire verticale. La configuration en spirale croissante du bas vers le haut permet de conférer une raideur qui est constante, et non pas décroissante. On peut remarquer que le ressort est réalisé à partir d'une lame de section rectangulaire enroulée en spirale. La section rectangulaire permet de garantir une bonne stabilité axiale du ressort. De plus, son moulage en matière plastique permet de réaliser un réservoir sans partie métallique. Il est à noter qu'un tel ressort peut être mis en oeuvre dans n'importe quel réservoir pour pousser un piston, et peut donc être protégé indépendamment du fait que le réservoir intègre un organe de déblocage.The spring 5 can be of any kind and any form, to the extent that it allows to fulfill its thrust function. In the embodiment used to illustrate the present invention, the spring 5 has several advantageous characteristics, and in particular its concentric spiral shape, its plastic embodiment, its vertical rectangular section. The ascending spiral configuration from bottom to top provides stiffness that is constant, not decreasing. It may be noted that the spring is made from a rectangular section blade wound spirally. The rectangular section ensures a good axial stability of the spring. Moreover, its plastic molding makes it possible to produce a tank without a metal part. It should be noted that such a spring can be implemented in any tank to push a piston, and can therefore be protected regardless of whether the tank incorporates an unlocking member.

Le piston 6 comprend un plateau 61 qui comprend en son centre un profil d'accrochage 62 qui fait saillie vers le bas. Ce profil d'accrochage 62 peut par exemple se présenter sous la forme d'un téton pourvu d'une tête saillante d'accrochage. Sur sa périphérie externe, le plateau 61 est pourvu d'une ceinture formant deux lèvres d'étanchéité 63. Pour renforcer la stabilité du piston 6, il est également prévu une jupe de renforcement 64 qui fait saillie vers le bas à l'intérieur de la ceinture.The piston 6 comprises a plate 61 which comprises in its center a hooking profile 62 which projects downwards. This snapping profile 62 may for example be in the form of a pin provided with a projecting hooking head. On its outer periphery, the plate 61 is provided with a belt forming two sealing lips 63. To enhance the stability of the piston 6, there is also provided a reinforcing skirt 64 which projects downwards inside the the belt.

On se référera maintenant à la figure 1 pour décrire en détail l'agencement des différentes pièces entre elles. Tout d'abord, le godet interne 4 est reçu à l'intérieur de la coque externe 1 de telle sorte que sa paroi de fond 41 s'étende à proximité ou en contact direct du fond 11. D'autre part, la collerette 48 vient en appui sur le bord supérieur du col 15. On peut remarquer que le diamètre de la douille de guidage 42 est légèrement supérieur à celui de l'ouverture d'accès 13 de sorte que le bord interne 12i est dégagé. D'autre part, le piston 6 est engagé à l'intérieur du fût de coulissement 47 de manière à définir au-dessus de lui un volume utile V. Le profil d'accrochage 62 est engagé entre les pattes souples 44 avec les têtes d'accrochage 45 en prise avec le profil d'accrochage 62. Le piston 6 est ainsi immobilisé à l'intérieur du godet interne 4. Il est cependant soumis à l'action du ressort 5 qui prend appui d'une part sur la bride annulaire 43 du godet interne 4 et d'autre part sous le plateau 61 à l'intérieur de la jupe de renforcement 64. Le ressort 5 est comprimé dans un état maximal, mais son action sur le piston 6 est inopérante, étant donné que ce dernier est maintenu en position bloquée de par l'engagement du profil d'accrochage 62 avec les pattes souples 44. Ainsi, le produit fluide stocké dans le volume utile V n'est soumis à aucune pression de la part du piston 6. Le réservoir est alors dans une position initiale.We will now refer to the figure 1 to describe in detail the arrangement of the different parts together. First, the inner cup 4 is received inside the outer shell 1 so that its bottom wall 41 extends near or in direct contact with the bottom 11. On the other hand, the flange 48 bears against the upper edge of the neck 15. It may be noted that the diameter of the guide sleeve 42 is slightly greater than that of the access opening 13 so that the inner edge 12i is clear. On the other hand, the piston 6 is engaged inside the sliding shaft 47 so as to define above it a useful volume V. The hooking profile 62 is engaged between the flexible tabs 44 with the heads of the piston. hooking 45 engaged with the hooking profile 62. The piston 6 is thus immobilized inside the inner cup 4. It is, however, subjected to the action of the spring 5 which is supported on the one hand on the annular flange 43 of the inner cup 4 and secondly under the plate 61 inside the reinforcing skirt 64. The spring 5 is compressed in a maximum state, but its action on the piston 6 is inoperative, since the latter is held in the locked position by the engagement of the attachment profile 62 with the flexible tabs 44. Thus, the fluid stored in the useful volume V is not subjected to any pressure from the piston 6. The reservoir is then in an initial position.

Selon l'invention, l'organe de déblocage 3 est disposé à l'intérieur de la coque externe 1 et du godet interne 4 avec son pointeau d'écartement 31 déjà engagé entre les pattes souples 44 et sa face d'appui 32 qui obture l'ouverture d'accès 13. Avantageusement, la face d'appui 32 vient en affleurement avec le bord externe 12e de manière à compléter parfaitement l'ouverture d'accès 13. On peut également remarquer que le rebord 34 vient en appui contre le bord interne 12i. La couronne de support et de guidage 33 est engagée avec un jeu réduit à l'intérieur de la douille de guidage 42. Il est à noter que dans cette position initiale, le pointeau d'écartement 31 ne sollicite pas les pattes souples 44, de sorte que l'on peut dire que l'organe de déblocage 3 est dans une position initiale inopérante.According to the invention, the unlocking member 3 is disposed inside the outer shell 1 and the inner cup 4 with its spacer needle 31 already engaged between the flexible tabs 44 and its bearing face 32 which closes The access opening 13. Advantageously, the bearing face 32 comes flush with the outer edge 12e so as to perfectly complete the access opening 13. It may also be noted that the flange 34 bears against the inner edge 12i. The support and guide ring 33 is engaged with a reduced clearance inside the guide sleeve 42. It should be noted that in this initial position, the spacer needle 31 does not solicit the flexible tabs 44, so that it can be said that the unlocking member 3 is in an initial inoperative position.

On peut également remarquer sur la figure 1 que l'étiquette de premier usage 2 est appliquée contre le fond 11 et l'organe de déblocage 3. Plus précisément, la pastille 21 adhère au bord externe 12e de l'ouverture d'accès 13 et à la face d'appui 32 de l'organe de déblocage 3. Lorsque la face d'appui 32 est disposée dans l'alignement du bord externe 12e, l'étiquette de premier usage 2 masque parfaitement l'ouverture d'accès 13 et l'organe de déblocage 3. L'utilisateur ne peut même pas savoir que le réservoir est équipé d'un organe de déblocage.We can also notice on the figure 1 that the first-use label 2 is applied against the bottom 11 and the unlocking member 3. More specifically, the pellet 21 adheres to the outer edge 12e of the access opening 13 and the bearing face 32 of 3. When the bearing face 32 is disposed in alignment with the outer edge 12e, the first-use label 2 perfectly masks the access opening 13 and the unlocking member 3. L The user can not even know that the tank is equipped with an unlocking device.

En se référant maintenant à la figure 2, on peut voir que l'étiquette de premier usage 2 a été retirée, ce qui a permis à l'utilisateur de déplacer l'organe de déblocage 3. En effet, dès que l'étiquette 2 est arrachée, l'utilisateur découvre la face d'appui 32 de l'organe de déblocage 3, et il peut appuyer à l'aide d'un doigt, par exemple l'index, de manière à enfoncer l'organe de déblocage 3 à l'intérieur du réservoir. Ce faisant, le rebord 34 se décolle du bord interne 12i, la couronne 33 coulisse à l'intérieur de la douille 42 jusqu'à ce qu'elle vienne en butée contre la bride annulaire 43. Simultanément, le pointeau d'écartement 41 est engagé à fond à l'intérieur des pattes souples 44 qui sont contraintes de se déplacer vers l'extérieur de sorte que leur tête d'accrochage 45 se dégage du profil d'accrochage 62 qui est ainsi libéré. Le piston 6 peut alors se déplacer sous l'action des forces de sollicitation élastiques générées par le ressort 5. Le produit fluide stocké dans le volume utile V est alors soumis à la pression exercée par le piston 6.Referring now to the figure 2 it can be seen that the first-use label 2 has been removed, which has enabled the user to move the unlocking member 3. Indeed, as soon as the label 2 is torn off, the user discovers the bearing face 32 of the unlocking member 3, and it can press with the aid of a finger, for example the index finger, so as to depress the release member 3 inside the tank. In doing so, the rim 34 comes off the inner edge 12i, the ring 33 slides inside the sleeve 42 until it abuts against the annular flange 43. Simultaneously, the spacer needle 41 is fully engaged within the flexible tabs 44 which are forced to move outwardly so that their attachment head 45 is disengaged from the attachment profile 62 which is thus released. The piston 6 can then move under the action of the elastic biasing forces generated by the spring 5. The fluid product stored in the useful volume V is then subjected to the pressure exerted by the piston 6.

On peut remarquer sur la figure 2 que l'organe de déblocage 3 a atteint une position finale opérante dans laquelle il est de préférence retenu dans les pattes souples 44. Le maintien de l'organe de déblocage 3 peut par exemple être réalisé par encliquetage ou par simple frottement.We can notice on the figure 2 that the unlocking member 3 has reached an operative final position in which it is preferably retained in the flexible tabs 44. The maintenance of the release member 3 may for example be achieved by snapping or by simple friction.

Grâce à l'invention, on dispose d'un réservoir à piston sollicité par ressort qui est maintenu en position initiale de repos et qui est débloqué au moyen d'un organe de déblocage qui est à peine visible, voire invisible, du fait que l'ouverture d'accès est réduite, que la face d'appui de l'organe de blocage obture parfaitement l'ouverture d'accès et qu'une étiquette de premier usage peut être apposée sur l'ouverture d'accès et l'organe de déblocage de manière à masquer entièrement l'organe de déblocage.Thanks to the invention, there is provided a spring loaded piston reservoir which is held in the initial rest position and which is unlocked at the means of an unlocking member which is barely visible, or even invisible, because the access opening is reduced, that the bearing surface of the locking member perfectly closes the access opening and that a first-use label may be affixed to the access opening and the unlocking member so as to completely mask the unlocking member.
