Description

Distributeur de produit fluide rechargeable  Refillable fluid product dispenser
La présente invention concerne un distributeur de produit fluide rechargeable comprenant une tête de distribution comprenant un organe de distribution (pompe ou valve par exemple), un réservoir de volume variable et un clapet de remplissage connecté au réservoir. Le domaine d'application privilégié de la présente invention est celui de la parfumerie, de la cosmétique ou encore de la pharmacie. Ce type de distributeur rechargeable est souvent désigné sous le terme de distributeur « nomade ». Il présente en général un réservoir de faible contenance de l'ordre de 10 ml au plus. The present invention relates to a refillable fluid product dispenser comprising a dispensing head comprising a dispensing member (pump or valve for example), a variable volume reservoir and a filling valve connected to the reservoir. The preferred field of application of the present invention is that of perfumery, cosmetics or even pharmacy. This type of refillable dispenser is often referred to as a "nomadic" distributor. It generally has a low capacity tank of the order of 10 ml at most.
Dans l'art antérieur, on connaît le document EP1588775 qui décrit un distributeur rechargeable comprenant une pompe, un fût fixe, et un organe coulissant comprenant un piston mobile apte à coulisser dans le fût fixe pour faire varier le volume du réservoir et un clapet de remplissage monté sur le piston mobile pour remplir le réservoir en produit fluide. Ce distributeur rechargeable est adapté à être monté sur un flacon source qui comprend une tige de connexion apte à venir en prise avec l'organe mobile de manière à forcer le clapet de remplissage à l'état ouvert. Lorsque le réservoir du distributeur rechargeable est vide, le piston mobile est disposé à proximité de la pompe et son déplacement vers le bas en tirant sur la tige de connexion du flacon source, crée une dépression à l'intérieur du réservoir, de sorte que du produit fluide provenant du flacon source est aspiré à l'intérieur du réservoir à travers le clapet de remplissage forcé à l'état ouvert. Lorsque le piston mobile arrive en butée contre l'extrémité inférieure du fût fixe, la tige de connexion se détache de l'organe coulissant de sorte que le clapet de remplissage peut revenir dans sa position de repos fermée. Le réservoir du distributeur rechargeable est alors à nouveau rempli de produit fluide, et l'utilisateur peut s'en servir en appuyant simplement sur le poussoir de la pompe, de manière tout à fait traditionnelle.  In the prior art, document EP1588775 describes a refillable dispenser comprising a pump, a fixed barrel, and a sliding member comprising a movable piston able to slide in the fixed barrel to vary the volume of the tank and a check valve. filling mounted on the movable piston to fill the reservoir with fluid product. This refillable dispenser is adapted to be mounted on a source bottle which comprises a connecting rod adapted to come into engagement with the movable member so as to force the filling valve to the open state. When the reservoir of the refillable dispenser is empty, the movable piston is placed near the pump and its downward movement by pulling on the connection rod of the source bottle, creates a depression inside the reservoir, so that Fluid product from the source flask is sucked into the tank through the forced fill valve in the open state. When the movable piston abuts against the lower end of the fixed barrel, the connecting rod is detached from the sliding member so that the filling valve can return to its closed rest position. The reservoir of the refillable dispenser is then refilled with fluid, and the user can use it by simply pressing the pusher of the pump, in a very traditional way.
Par conséquent, le distributeur rechargeable du document EP1588775 est rechargeable par traction, c'est-à-dire en saisissant le distributeur rechargeable et en le tirant vers le haut pour l'éloigner du flacon source, et finalement le détacher. Au préalable, il est bien entendu nécessaire de rapporter le distributeur rechargeable vide sur le flacon source jusqu'à ce que la tige de connexion vienne en prise avec l'organe coulissant qui forme le piston mobile supportant le clapet de remplissage. De ce fait, la gestuelle nécessaire pour le rechargement de ce distributeur n'est pas intuitive ou évidente. De plus il est nécessaire de maintenir le flacon nomade en appui sur la pompe du flacon source afin de maintenir en position ouverte le clapet haut de la pompe du flacon source. Cette gestuelle antagoniste de maintien en appui vers le flacon source et d'étirement de la seringue vers le haut n'est pas ergonomique et peut conduire à dégrader le processus de remplissage du nomade. Therefore, the refillable dispenser of the EP1588775 document is refillable by traction, that is to say by entering the distributor rechargeable and pulling it upward away from the source bottle, and finally detaching it. Beforehand, it is of course necessary to bring the empty refillable dispenser to the source bottle until the connecting rod comes into engagement with the sliding member which forms the movable piston supporting the filling valve. As a result, the gestures necessary for reloading this dispenser are not intuitive or obvious. In addition it is necessary to keep the nomadic flask resting on the pump of the source flask in order to keep the top flap of the pump of the source flask open. This antagonistic gesture maintaining support towards the source bottle and stretching of the syringe upward is not ergonomic and can lead to degrade the process of filling the nomad.
Il faut également remarquer qu'une autre caractéristique du distributeur rechargeable de ce document est qu'il est possible de se servir du distributeur rechargeable alors qu'il est monté sur le flacon source, du fait de la liaison directe entre la pompe et la tige de connexion sans passer par le réservoir du distributeur rechargeable.  It should also be noted that another characteristic of the refillable dispenser of this document is that it is possible to use the refillable dispenser while it is mounted on the source bottle, because of the direct connection between the pump and the stem connection without passing through the reservoir of the refillable dispenser.
La présente invention a pour but de définir un distributeur rechargeable dont la gestuelle pour le rechargement est plus simple, plus intuitive ou plus évidente pour un utilisateur non averti. Un autre but de la présente invention est pouvoir recharger le distributeur rechargeable à l'aide d'un flacon source standard équipé d'une tige de soupape classique, contrairement au flacon source du document EP1588775. Encore un autre but de la présente invention est de rechercher une architecture de réservoir à volume variable qui engendre ou impose une gestuelle de manipulation différente.  The present invention aims to define a refillable dispenser whose gesture for reloading is simpler, more intuitive or more obvious to an uninformed user. Another object of the present invention is to refill the refillable dispenser with a standard source bottle equipped with a conventional valve stem, unlike the source bottle of EP1588775. Yet another object of the present invention is to seek a variable volume reservoir architecture that generates or imposes a different manipulation gesture.
Pour ce faire, la présente invention propose que l'organe de distribution soit pourvu d'un tube plongeur qui traverse le réservoir, un organe coulissant comprenant un piston mobile coulissant en contact étanche autour du tube plongeur de manière à faire varier le volume du réservoir, l'organe coulissant étant déplaçable entre une position enfoncée dans laquelle l'organe coulissant est situé à proximité de l'organe de distribution et une position étendue dans laquelle l'organe coulissant est éloigné de l'organe de distribution, le réservoir définissant un volume maximum en position enfoncé et un volume minimum en position étendue, de sorte que le volume du réservoir croît lorsque l'organe coulissant est enfoncé autour du tube plongeur vers l'organe de distribution, le tube plongeur étant pourvu d'un piston fixe qui coulisse en contact étanche dans un fût mobile formé par l'organe coulissant, le piston mobile coulissant autour du tube plongeur entre l'organe de distribution et le piston fixe, le réservoir étant délimité axialement entre le piston mobile et le piston fixe et radialement entre le tube plongeur et le fût mobile. To do this, the present invention proposes that the dispensing member is provided with a dip tube which passes through the reservoir, a sliding member comprising a movable piston sliding in sealed contact around the dip tube so as to vary the volume of the reservoir. , the sliding member being movable between a recessed position in which the sliding member is located near the body of distribution and an extended position in which the sliding member is remote from the dispensing member, the tank defining a maximum volume in the depressed position and a minimum volume in the extended position, so that the volume of the reservoir increases when the sliding member is pressed around the plunger tube towards the dispensing member, the plunger tube being provided with a fixed piston which slides in sealing contact in a mobile shaft formed by the sliding member, the movable piston sliding around the plunger tube between the dispensing member and the fixed piston, the reservoir being delimited axially between the movable piston and the fixed piston and radially between the dip tube and the mobile drum.
Ainsi, le remplissage du réservoir s'effectue en appuyant le distributeur contre le flacon source, et non pas en tirant sur le distributeur comme c'est le cas dans le document EP1588775. Cela répond à une gestuelle tout à fait classique intuitive qui veut que l'on appuie sur le flacon source pour remplir ou recharger le réservoir.  Thus, the tank is filled by pressing the dispenser against the source bottle, and not by pulling on the dispenser as is the case in EP1588775. This responds to a gesture quite classic intuitive that wants to press the source bottle to fill or refill the tank.
Ainsi, le réservoir est vide ou pratiquement vide lorsque les deux pistons sont rapprochés au maximum et plein ou pratiquement plein lorsqu'ils sont éloignés au maximum. On peut aussi dire que le réservoir est plein ou pratiquement plein, lorsque le piston mobile est le plus prêt possible de l'organe de distribution. On peut également dire que le réservoir est vide lorsque l'organe coulissant est étendu au maximum. Il suffit alors à l'utilisateur de positionner le clapet de remplissage sur la tige de soupape d'un flacon source et d'appuyer dessus jusqu'à ce que l'organe coulissant arrive en butée en position enfoncée proche de l'organe de distribution.  Thus, the reservoir is empty or virtually empty when the two pistons are close to the maximum and full or almost full when they are at the maximum distance. It can also be said that the tank is full or substantially full, when the movable piston is as close as possible to the dispensing member. It can also be said that the reservoir is empty when the sliding member is extended to the maximum. It then suffices for the user to position the filling valve on the valve stem of a source bottle and to press on it until the sliding member reaches its abutment in a depressed position close to the dispensing member. .
Selon une caractéristique intéressante, le tube plongeur est en permanence solidaire de l'organe de distribution et le clapet de remplissage est en permanence solidaire de l'organe coulissant.  According to an interesting characteristic, the plunger tube is permanently secured to the dispensing member and the filling valve is permanently secured to the sliding member.
Selon une autre caractéristique avantageuse, le clapet de remplissage communique avec le réservoir à travers une chambre intermédiaire de volume variable inversement à celui du réservoir. Autrement dit, le réservoir de distribution se remplit lorsque la chambre intermédiaire se vide. De préférence, le volume du réservoir de distribution est plus grand que celui de la chambre intermédiaire. D'autre part, la chambre intermédiaire peut communiquer avec le réservoir à travers au moins un canal fixe qui est solidaire du tube plongeur. Selon un mode de réalisation pratique, un manchon fixe est engagé autour du tube plongeur de manière à définir entre eux ledit au moins un canal fixe, ce manchon fixe définissant une extrémité inférieure libre formant une lèvre d'étanchéité qui est engagée à coulissement étanche dans une tubulure mobile solidaire de l'organe coulissant, définissant ainsi la chambre intermédiaire, le piston fixe étant avantageusement formé par le manchon fixe. According to another advantageous characteristic, the filling valve communicates with the reservoir through an intermediate chamber of variable volume inversely to that of the reservoir. In other words, the dispensing tank fills when the intermediate chamber empties. Preferably, the volume of the distribution tank is larger than that of the intermediate chamber. On the other hand, the intermediate chamber can communicate with the reservoir through at least one fixed channel which is integral with the dip tube. According to a practical embodiment, a fixed sleeve is engaged around the dip tube so as to define between them said at least one fixed channel, this fixed sleeve defining a free bottom end forming a sealing lip which is engaged with a watertight sliding a movable tubular integral with the sliding member, thus defining the intermediate chamber, the fixed piston being advantageously formed by the fixed sleeve.
Selon un autre aspect avantageux de l'invention, le piston mobile est formé à une extrémité du fût mobile et le clapet de remplissage est monté à l'autre extrémité du fût mobile.  According to another advantageous aspect of the invention, the movable piston is formed at one end of the mobile drum and the filling valve is mounted at the other end of the mobile drum.
Selon un mode de réalisation pratique, le clapet de remplissage comprend un support de clapet engagé dans le fût mobile et formant une tubulure mobile dans laquelle est engagée une lèvre d'étanchéité, définissant ainsi ensemble un réservoir intermédiaire à travers lequel le clapet de remplissage communique avec le réservoir.  According to a practical embodiment, the filling valve comprises a valve support engaged in the mobile drum and forming a movable tube in which is engaged a sealing lip, thus together defining an intermediate reservoir through which the filling valve communicates. with the tank.
Selon une caractéristique avantageuse de l'invention, le distributeur comprend en outre un étui solidaire du tube plongeur et dans lequel l'organe coulissant est déplaçable par coulissement étanche autour du tube plongeur. Avantageusement, l'étui définit une extrémité inférieure ouverte à travers laquelle l'organe coulissant fait saillie en position étendue, l'organe coulissant étant avantageusement pourvu d'un marquage d'indication d'état de remplissage du réservoir. Selon, un mode de réalisation préférentiel, l'étui est pourvu d'un capot qui obture l'extrémité inférieure ouverte, ce capot formant avantageusement une fenêtre de lecture laissant apparaître d'un marquage d'indication d'état de remplissage du réservoir apposé sur l'organe coulissant.  According to an advantageous characteristic of the invention, the dispenser further comprises a holster integral with the dip tube and in which the sliding member is movable by leaktight sliding around the dip tube. Advantageously, the case defines an open bottom end through which the sliding member protrudes in the extended position, the sliding member being advantageously provided with a tank fill status indication marking. According to a preferred embodiment, the case is provided with a cover which closes the open bottom end, this cover advantageously forming a reading window revealing a marking indicating the filling status of the tank affixed on the sliding organ.
Selon une autre caractéristique particulièrement avantageuse, l'organe coulissant est sollicité élastiquement vers la position étendue par un ressort. Ce ressort peut par exemple agir entre le clapet de remplissage et le manchon fixe. Selon une définition plus structurelle de l'invention, le distributeur de produit fluide rechargeable comprend une tête de distribution intégrant un organe de distribution avec un tube plongeur, According to another particularly advantageous characteristic, the sliding member is biased elastically towards the extended position by a spring. This spring can for example act between the filling valve and the fixed sleeve. According to a more structural definition of the invention, the rechargeable fluid dispenser comprises a dispensing head incorporating a dispensing member with a dip tube,
caractérisé en ce qu'il comprend en outre :  characterized in that it further comprises:
- un organe coulissant formant un fût mobile et un piston mobile, a sliding member forming a mobile drum and a movable piston,
- un manchon fixe formant un piston fixe et une lèvre d'étanchéité,a fixed sleeve forming a fixed piston and a sealing lip,
- un clapet de remplissage comprenant un support de clapet formant une tubulure mobile, a filling valve comprising a valve support forming a mobile pipe,
dans lequel :  in which :
- le piston mobile est engagé à coulissement étanche autour du tube plongeur,  the movable piston is engaged in leaktight sliding around the dip tube,
- le manchon fixe est engagé fixement autour du tube plongeur en créant entre eux au moins un canal fixe, le piston fixe étant engagé à coulissement étanche dans le fût mobile, the fixed sleeve is fixedly engaged around the plunger tube, creating between them at least one fixed channel, the fixed piston being slidably engaged in the mobile shaft,
- le support de clapet est engagé fixement dans le fût mobile, avec sa tubulure mobile engagé autour de la lèvre d'étanchéité. - The valve support is fixedly engaged in the mobile drum, with its movable tubing engaged around the sealing lip.
A partir de cette définition structurelle, on peut définir un procédé de montage, dans lequel l'organe coulissant, le manchon fixe et le support de clapet sont successivement engagés l'un après l'autre de manière axiale sans orientation angulaire. Avantageusement, un ressort est engagé ou inséré entre le manchon fixe et le support de clapet.  From this structural definition, it is possible to define a mounting method in which the sliding member, the fixed sleeve and the valve support are successively engaged one after the other axially without angular orientation. Advantageously, a spring is engaged or inserted between the fixed sleeve and the valve support.
L'esprit de la présente invention réside dans le fait de reconfigurer le réservoir de sorte que son remplissage s'effectue avec un déplacement de l'organe coulissant qui est à l'opposé de celui pour une seringue traditionnelle, où il faut tirer sur le piston pour remplir le réservoir. La traversée du réservoir par le tube plongeur, l'engagement de l'organe coulissant autour du tube plongeur, la mise en œuvre d'un manchon fixe pour former les canaux et/ou le piston fixe, la formation d'une chambre intermédiaire, le renvoi élastique de l'organe coulissant vers la position étendue, l'utilisation d'un capot avantageusement ajouré pour voir à travers les graduations d'état de remplissage du réservoir sont des caractéristiques de l'invention qui peuvent être mises en œuvre individuellement ou de manière combinée. The spirit of the present invention resides in reconfiguring the reservoir so that its filling is effected with a displacement of the sliding member which is the opposite of that for a traditional syringe, where it is necessary to draw on the piston to fill the tank. The passage of the reservoir through the dip tube, the engagement of the sliding member around the dip tube, the implementation of a fixed sleeve to form the channels and / or the fixed piston, the formation of an intermediate chamber, the elastic return of the sliding member to the extended position, the use of a hood advantageously perforated to see through the fill level graduations of the tank are characteristics of the invention which can be implemented individually or in combination.
L'invention sera maintenant plus amplement décrite, en référence aux dessins joints, donnant à titre d'exemple non limitatif, un mode de réalisation de l'invention.  The invention will now be more fully described, with reference to the accompanying drawings, giving by way of non-limiting example, an embodiment of the invention.

On se référera tout d'abord aux figures 1 et 2 pour décrire en détail la structure d'un distributeur réalisé selon l'invention. Le distributeur rechargeable comprend une tête de distribution T et un récipient qui sont associés pour former ensemble le distributeur. La tête de distribution T peut être une tête de distribution tout à fait classique avec un organe de distribution D, comme par exemple une pompe, une valve ou encore un clapet de distribution. Dans le cas d'une pompe ou d'une valve, elle comprend un corps définissant une entrée de produit fluide sous la forme d'une tubulure d'entrée axiale E. La pompe ou valve comprend également une tige d'actionnement (non représentée) sur laquelle est monté un bouton- poussoir B. Par enfoncement du bouton-poussoir B, du produit fluide est mis sous pression dans une chambre définie à l'intérieur du corps. Le bouton- poussoir B peut définir un orifice de distribution par lequel le produit fluide refoulé hors de la chambre est distribué sous forme pulvérisé, de jet ou de gouttes. Pour la fixation de la pompe sur le récipient, il est prévu un organe de fixation F qui maintient le corps fixement et qui s'accroche sur un col ou une ouverture du récipient. Un capuchon amovible C peut optionnellement coiffer l'organe de distribution D et le bouton-poussoir B. Il s'agit là d'une conception tout à fait classique pour une tête de distribution dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie. Etant donné que la tête de distribution n'est pas l'entité critique de la présente invention, elle ne sera pas décrite plus amplement. Referring first to Figures 1 and 2 to describe in detail the structure of a dispenser made according to the invention. The refillable dispenser includes a dispensing head T and a container that are associated to form the dispenser together. The dispensing head T can be a dispensing head quite conventional with a dispensing member D, such as a pump, a valve or a dispensing valve. In the case of a pump or a valve, it comprises a body defining a fluid product inlet in the form of an axial inlet manifold E. The pump or valve also comprises an actuating rod (not shown ) on which is mounted a pushbutton B. By pressing the pushbutton B, fluid is pressurized in a chamber defined inside the body. The push-button B may define a dispensing orifice through which the fluid product discharged from the chamber is dispensed in spray, jet or droplet form. For fixing the pump on the container, there is provided a fixing member F which holds the body fixedly and which clings to a collar or an opening of the container. A removable cap C may optionally cover the dispensing member D and the push button B. This is a quite conventional design for a dispensing head in the field of perfumery, cosmetics or from the pharmacy. Since the dispensing head is not the critical entity of the present invention, it will not be described further.
Le récipient sur lequel la tête de distribution T est montée présente une forme particulière qui ne doit pas être considérée comme limitative dans sa structure. Le terme « récipient » doit être considéré comme le sous ensemble bas complet qui coopère avec le sous ensemble haut formé par la tête de distribution T. Le récipient intègre un réservoir de produit fluide R et d'autres organes fonctionnels, comme on le verra ci-après. Dans cette forme de réalisation particulière non limitative, le récipient forme un tube plongeur 23 auquel se raccorde l'entrée E de l'organe de distribution D de la tête de distribution T. Sans sortir du cadre de l'invention, il est tout à fait possible d'intégrer le tube plongeur 23 à la tête de distribution T et non pas au récipient.  The container on which the dispensing head T is mounted has a particular shape which should not be considered as limiting in its structure. The term "container" should be considered as the complete low subassembly which cooperates with the upper subset formed by the dispensing head T. The container incorporates a fluid reservoir R and other functional organs, as will be seen here. -after. In this particular non-limiting embodiment, the container forms a dip tube 23 to which the inlet E of the dispensing member D of the dispensing head T is connected. Without departing from the scope of the invention, it is all makes it possible to integrate the dip tube 23 to the dispensing head T and not to the container.
Le récipient comprend plusieurs pièces constitutives, à savoir un étui 1 , un insert 2, un organe coulissant 3, un manchon fixe 4, un ressort 5, un support de clapet 6, un clapet de remplissage 7 et optionnellement un capot 8. Toutes ces pièces ne doivent pas être considérées comme essentielles et figées dans leur structure.  The container comprises a plurality of component parts, namely a case 1, an insert 2, a sliding member 3, a fixed sleeve 4, a spring 5, a valve support 6, a filling valve 7 and optionally a cover 8. parts should not be considered essential and fixed in their structure.
L'étui 1 comprend une enveloppe externe 1 1 qui peut présenter n'importe quelle forme géométrique, comme par exemple cylindrique circulaire, comme c'est le cas sur les figures. L'étui 1 comprend également un épaulement rentrant 12 à son extrémité supérieure et un profil d'accrochage intérieur 18 à son extrémité inférieure. L'enveloppe externe 1 1 est normalement visible de l'extérieur et destinée à être saisie par l'utilisateur de manière à pouvoir appuyer sur le bouton poussoir B à l'aide de son index.  The case 1 comprises an outer envelope January 1 which can have any geometric shape, such as circular cylindrical, as is the case in the figures. The case 1 also comprises a reentrant shoulder 12 at its upper end and an inner hooking profile 18 at its lower end. The outer envelope 1 1 is normally visible from the outside and intended to be grasped by the user so as to press the push button B with his index finger.
L'insert 2 comprend un plateau annulaire 21 qui fait saillie radialement vers l'extérieur. On peut voir que ce plateau 21 est disposé juste en dessous de l'épaulement rentrant 12 de l'étui 1 1 sur la figure 1 . Un col 22 s'étend vers le haut à partir du plateau 21 : il présente de préférence un profil d'accrochage apte à coopérer avec la bague de fixation F de la tête de distribution T. L'insert 2 forme également le tube plongeur 23 qui s'étend vers le bas. Ce tube plongeur 23 comprend une section supérieure 24 et une section inférieure 25 de diamètre réduit. La paroi externe de la section supérieure 24 est de préférence cylindrique circulaire. A son extrémité inférieure libre, la section inférieure 25 forme plusieurs dents d'encliquetage 26 dont la fonction sera donnée ci-après. La paroi externe de la section inférieure 25 peut être parfaitement cylindrique circulaire, ou encore formée avec des nervures verticales, définissant entre elles des saignées en creux.The insert 2 comprises an annular plate 21 which protrudes radially outwards. It can be seen that this plate 21 is placed just below the reentrant shoulder 12 of the case 1 1 in FIG. A collar 22 extends towards the top from the plate 21: it preferably has a hooking profile adapted to cooperate with the fixing ring F of the dispensing head T. The insert 2 also forms the dip tube 23 which extends downwards . This dip tube 23 comprises an upper section 24 and a lower section 25 of reduced diameter. The outer wall of the upper section 24 is preferably circular cylindrical. At its lower free end, the lower section 25 forms a plurality of ratchet teeth 26 whose function will be given below. The outer wall of the lower section 25 may be perfectly cylindrical circular, or formed with vertical ribs, defining between them recessed grooves.
A la jonction entre la section supérieure 24 et la section inférieure 25 est formé un épaulement orienté vers le bas. At the junction between the upper section 24 and the lower section 25 is formed a shoulder oriented downwards.
Sans sortir du cadre de l'invention, il est tout à fait possible de réaliser le col 22 et le plateau 21 de manière monobloc avec l'étui 1 1 et de connecter directement le tube plongeur 23 à l'entrée E de l'organe de distribution D. Without departing from the scope of the invention, it is quite possible to make the neck 22 and the plate 21 integrally with the case 1 1 and directly connect the dip tube 23 to the inlet E of the organ D. Distribution
Selon une autre variante, il est également possible de faire passer un tube plongeur raccordé à l'entrée E à travers l'insert 2 pourvu d'un tube, non plus plongeur, mais capable d'accueillir à l'intérieur le tube plongeur de l'organe de distribution D. According to another variant, it is also possible to pass a dip tube connected to the inlet E through the insert 2 provided with a tube, no longer a plunger, but capable of receiving inside the plunger tube the distribution member D.
L'organe coulissant 3 est une pièce mobile par rapport à l'étui 1 et à l'insert 2. Cet organe coulissant 3 comprend un fût mobile 31 de forme cylindrique, de préférence circulaire. A son extrémité supérieure, l'organe coulissant 3 comprend une bride radiale 34 qui se termine intérieurement par un piston mobile 35 qui vient en contact de coulissement étanche avec la paroi externe du tube plongeur 23, au niveau de sa section supérieure 24. A son extrémité inférieure, le fût mobile 31 forme intérieurement un profil d'accrochage dont la fonction sera donnée ci-après. L'organe coulissant 31 est de préférence réalisé de manière monobloc avec une ou plusieurs matière(s) plastique(s) différente(s). On peut par exemple imaginer que le piston mobile 35 soit réalisé en un matériau plus souple que le fût mobile 31 . The sliding member 3 is a movable piece relative to the case 1 and the insert 2. This sliding member 3 comprises a movable shaft 31 of cylindrical shape, preferably circular. At its upper end, the sliding member 3 comprises a radial flange 34 which ends internally by a movable piston 35 which comes into sealing contact with the outer wall of the dip tube 23, at its upper section. lower end, the movable shaft 31 internally forms a fastening profile whose function will be given below. The sliding member 31 is preferably made in one piece with one or more plastic material (s) different (s). For example, it can be imagined that the mobile piston 35 is made of a more flexible material than the mobile shaft 31.
On peut remarquer sur la figure 2 que la paroi externe du fût mobile 31 est pourvue d'un marquage lisible fournissant une indication sur l'état de remplissage du réservoir R. It can be seen in FIG. 2 that the outer wall of the mobile shaft 31 is provided with a legible marking giving an indication of the state of filling of the tank R.
Le manchon fixe 4 est engagé fixement autour de la section inférieure 25 du tube plongeur 23. Plus précisément, ce manchon fixe 4 comprend une gaine 41 qui est engagé à frottement autour de la section inférieure 25. La paroi interne de cette gaine 41 peut être parfaitement cylindrique, ou encore formée avec des nervures radiales définissant entre elles des saignées en creux. Quoiqu'il en soit, un ou plusieurs canaux 43 sont formés entre la gaine The fixed sleeve 4 is fixedly engaged around the lower section 25 of the plunger tube 23. More specifically, this fixed sleeve 4 comprises a sheath 41 which is frictionally engaged around the lower section 25. The inner wall of this sheath 41 may be perfectly cylindrical, or formed with radial ribs defining between them hollow grooves. Be that as it may, one or more channels 43 are formed between the sheath
41 et la section inférieure 25 : ces canaux 43 s'étendent sur toute la hauteur de la gaine 41 de manière à déboucher de part et d'autre. Le manchon fixe 4 forme également une couronne 44 qui s'étend radialement vers l'extérieur pour former sur sa périphérie externe un piston fixe 45 qui est en contact coulissant étanche avec le fût mobile 31 de l'organe coulissant 3. Pour garantir la fixation du manchon 4 autour de la partie inférieure 25 du tube plongeur 23, les têtes d'encliquetage 26 peuvent venir en prise en dessous des nervures formées à l'intérieur de la gaine 41 . On peut également remarquer que l'extrémité libre de la gaine 41 forme une lèvre d'étanchéité41 and the lower section 25: these channels 43 extend over the entire height of the sheath 41 so as to open on both sides. The fixed sleeve 4 also forms a ring 44 which extends radially outwardly to form on its outer periphery a fixed piston 45 which is in sliding sealing contact with the mobile shaft 31 of the sliding member 3. In order to guarantee the fixation of the sleeve 4 around the lower part 25 of the plunger tube 23, the detent heads 26 can engage below the ribs formed inside the sheath 41. It may also be noted that the free end of the sheath 41 forms a sealing lip
42 dont la fonction sera donnée ci-après. 42 whose function will be given below.
Un réservoir R est ainsi formé à l'intérieur du récipient. Plus précisément, ce réservoir R est délimité axialement entre la bride 34 (avec son piston mobile 35) et la couronne 44 (avec son piston fixe 45) et radialement entre le fût mobile 31 et la paroi externe de la section supérieure 24 du tube plongeur 23. On comprend aisément que le volume du réservoir est variable, étant donné que l'organe coulissant 3 peut se déplacer à l'intérieur de l'étui 1 avec son piston mobile 35 en contact de coulissement étanche autour du tube plongeur 23. Simultanément, le fût mobile 31 se déplace par rapport au piston fixe 45 du manchon 4.  A reservoir R is thus formed inside the container. More specifically, this reservoir R is defined axially between the flange 34 (with its movable piston 35) and the ring 44 (with its fixed piston 45) and radially between the movable shaft 31 and the outer wall of the upper section 24 of the dip tube 23. It is easily understood that the volume of the reservoir is variable, since the sliding member 3 can move inside the case 1 with its movable piston 35 in sealing contact around the dip tube 23. Simultaneously , the mobile shaft 31 moves relative to the fixed piston 45 of the sleeve 4.
Le support de clapet 6 comprend une douille de fixation 61 qui est engagée à force à l'intérieur du fût mobile 31 de l'organe coulissant 3. Cette douille 61 coopère avec le profil d'accrochage 33 pour garantir son maintien en place. Le support de clapet 6 forme également un logement de réception 62 pour le clapet de remplissage 7 qui peut être de conception tout à fait classique. Il peut s'agir d'un clapet à ouverture mécanique ou encore un clapet à ouverture hydraulique. Sa conception fine n'est pas critique pour la présente invention. Le support de clapet 6 forme également une tubulure mobile 63 qui est engagée autour de la gaine 41 qui forme à son extrémité inférieure la lèvre d'étanchéité 42. Ainsi, une chambre intermédiaire I est formée à l'intérieur de la tubulure mobile 63 au-dessus de l'entrée du tube plongeur 23. The valve support 6 comprises a fixing sleeve 61 which is forcibly engaged inside the mobile shaft 31 of the sliding member 3. This sleeve 61 cooperates with the attachment profile 33 to ensure its retention in place. The valve support 6 also forms a receiving housing 62 for the filling valve 7 which may be of quite different design. classic. It can be a valve with mechanical opening or a hydraulic opening valve. Its fine design is not critical for the present invention. The valve support 6 also forms a movable tubing 63 which is engaged around the sheath 41 which forms at its lower end the sealing lip 42. Thus, an intermediate chamber I is formed inside the movable tubing 63 at the end. above the inlet of the dip tube 23.
Le ressort 5 est engagé autour de la tubulure mobile 63 en prenant appui d'une part contre la couronne 44 et d'autre part contre le support de clapet 6. L'action du ressort 5 a pour effet de solliciter la bride 34 (avec son piston mobile 35) vers la couronne 44 (avec son piston fixe 45). En d'autres termes, le ressort 5 a pour effet de réduire le volume utile du réservoir R. On comprend alors aisément que le ressort 5 a pour effet d'induire ou de faciliter le déplacement coulissant de l'organe coulissant 3 à mesure que du produit fluide est extrait du réservoir R. Il est à noter que le ressort 5 est une pièce optionnelle, mais qui procure des avantages intéressants dans certains cas d'application. Il est même indispensable lorsque la tête de distribution T intègre une valve ou un clapet de distribution. Lorsque l'organe de distribution D est une pompe, l'utilité du ressort 5 est discutable.  The spring 5 is engaged around the movable tubing 63 while being supported on the one hand against the crown 44 and on the other hand against the valve support 6. The action of the spring 5 has the effect of urging the flange 34 (with its movable piston 35) towards the ring 44 (with its fixed piston 45). In other words, the spring 5 has the effect of reducing the effective volume of the reservoir R. It is then easily understood that the spring 5 has the effect of inducing or facilitating the sliding movement of the sliding member 3 as fluid is extracted from the reservoir R. It should be noted that the spring 5 is an optional part, but which provides interesting advantages in some cases of application. It is even essential when the dispensing head T incorporates a valve or a dispensing valve. When the dispensing member D is a pump, the utility of the spring 5 is debatable.
Le capot 8 comprend un bord d'accrochage supérieur 81 destiné à coopérer avec le profil d'accrochage 18 de l'étui 1 . Bien entendu, le capot 8 est amovible de manière à pouvoir accéder au clapet de remplissage 7. Avantageusement, le capot 8 comprend une fenêtre de lecture 82 à travers laquelle le marquage d'indication de remplissage 32 est visible. Le capot 8 est une pièce optionnelle, qui permet néanmoins de compléter l'étui 1 de manière esthétique. En variante, on peut imaginer que le fond du capot 8 soit ouvert de manière à permettre un accès par le bas au clapet de remplissage 7. Dans ce cas, le capot 8 pourrait être intégré à l'étui 1 .  The cover 8 comprises an upper engaging edge 81 intended to cooperate with the attachment profile 18 of the case 1. Of course, the cover 8 is removable so as to access the filling valve 7. Advantageously, the cover 8 comprises a read window 82 through which the filling indication marking 32 is visible. The cover 8 is an optional part, which nevertheless makes it possible to complete the case 1 in an aesthetic manner. Alternatively, one can imagine that the bottom of the cover 8 is open to allow access from below to the filling valve 7. In this case, the cover 8 could be integrated in the case 1.
En se référant à nouveau à la figure 1 , on peut maintenant constater que le réservoir R est rempli et présente donc un volume maximal. La bride 34 est en butée contre le plateau 21 . A l'inverse, la chambre intermédiaire I présente un volume minimal, étant donné que la lèvre d'étanchéité 42 vient presque en butée contre le fond de la tubulure mobile 63. Toutefois, le réservoir R communique avec la chambre intermédiaire I à travers les canaux 43. D'autre part, le tube plongeur 23 communique directement avec la chambre intermédiaire I, de sorte que l'entrée E de l'organe de distribution D est en communication de fluide avec le réservoir R. Ainsi, l'actionnement du bouton poussoir B a pour effet de distribuer du produit fluide en provenance du réservoir R. Le produit fluide du réservoir R chemine à travers les canaux 43, la chambre intermédiaire I et le tube plongeur 23 jusqu'à l'entrée E de l'organe de distribution D. Le produit fluide peut être distribué à travers un orifice de distribution formé au niveau du bouton poussoir B. Referring again to Figure 1, it can now be seen that the reservoir R is filled and therefore has a maximum volume. The flange 34 is in abutment against the plate 21. Conversely, the intermediate chamber I has a minimum volume, since the sealing lip 42 comes almost in abutment against the bottom of the movable tubing 63. However, the tank R communicates with the intermediate chamber I through the channels 43. On the other hand, the dip tube 23 communicates directly with the intermediate chamber I, so that the The inlet E of the dispenser member D is in fluid communication with the reservoir R. Thus, the actuation of the pushbutton B has the effect of dispensing fluid from the reservoir R. The fluid product of the reservoir R travels through the channels 43, the intermediate chamber I and the dip tube 23 to the inlet E of the dispensing member D. The fluid product can be dispensed through a dispensing orifice formed at the push button B.
A mesure que du produit fluide du réservoir R est distribué, l'organe mobile 3 se déplace vers le bas en éloignement de l'organe de distribution D. Il se crée ainsi entre le plateau 21 et la bride 34 un espace mort M qui communique avec l'extérieur entre l'étui 1 et le fût mobile 31 . Cet état du distributeur est représenté sur la figure 3, sur laquelle on peut voir que le réservoir R est à moitié rempli ou vide. On peut constater que la chambre intermédiaire I a augmenté de volume, étant donné que le support de clapet 6, qui est solidaire de l'organe coulissant 3 s'est déplacé vers le bas, alors que le manchon fixe 4 est resté en place sur le tube plongeur. On peut ainsi dire que le volume du réservoir R diminue à mesure que le volume de la chambre intermédiaire I et de l'espace mort M augmente. Cependant, il faut remarquer que la section de la chambre intermédiaire I est bien inférieure à celle du réservoir R, de sorte que le volume de la chambre intermédiaire I augmente moins vite que le volume du réservoir ne diminue, et vice versa. Etant donné que l'organe coulissant 3 se déplace vers le bas, son extrémité inférieure sort de plus en plus de l'étui 1 laissant ainsi apparaître le marquage d'indication 32. La figure 3 a été représentée sans le capot 8, mais celui-ci peut très bien rester en place, puisque sa hauteur permet le déplacement de l'organe de coulissement 3 et le marquage d'indication 32 est visible à travers la fenêtre de lecture 82.  As the fluid product of the tank R is distributed, the movable member 3 moves downwardly away from the dispensing member D. Thus, between the plate 21 and the flange 34 a dead space M is formed which communicates with the outside between the case 1 and the mobile shaft 31. This state of the dispenser is shown in Figure 3, on which it can be seen that the tank R is half filled or empty. It can be seen that the intermediate chamber I has increased in volume, since the valve support 6, which is integral with the sliding member 3 has moved down, while the fixed sleeve 4 has remained in place on the dip tube. It can thus be said that the volume of the tank R decreases as the volume of the intermediate chamber I and the dead space M increases. However, it should be noted that the cross section of the intermediate chamber I is much smaller than that of the tank R, so that the volume of the intermediate chamber I increases less rapidly than the volume of the tank decreases, and vice versa. Since the sliding member 3 moves downwards, its lower end leaves more and more of the case 1 thus leaving the indication mark 32. Figure 3 has been shown without the cover 8, but that it can very well remain in place, since its height allows the displacement of the sliding member 3 and the indication marking 32 is visible through the read window 82.
La distribution de produit fluide se poursuit jusqu'à ce que le réservoir R soit complètement vide. On se trouve alors dans la configuration représentée sur la figure 4. Le volume de réservoir R est pratiquement nul, alors que les volumes de la chambre intermédiaire I et de l'espace mort M sont au maximum. L'organe coulissant 3 est alors dans sa position étendue dans laquelle le piston mobile 35 est le plus éloigné de l'organe de distribution D. On peut même remarquer que le piston mobile 35 est pratiquement à la même hauteur axiale que le piston fixe 45. La lèvre d'étanchéité 42 est positionnée au niveau de l'extrémité supérieure de la tubulure mobile 63. Fluid dispensing continues until the reservoir R is completely empty. We are then in the configuration As shown in FIG. 4, the reservoir volume R is practically zero, whereas the volumes of the intermediate chamber I and the dead space M are at most. The sliding member 3 is then in its extended position in which the movable piston 35 is furthest away from the dispensing member D. It may even be noted that the movable piston 35 is substantially at the same axial height as the fixed piston 45 The sealing lip 42 is positioned at the upper end of the movable tubing 63.
Afin de remplir à nouveau le réservoir R, l'utilisateur peut disposer le clapet de remplissage 7 sur la tige de soupape S1 d'un flacon source S, comme représenté sur la figure 5. Il suffit alors à l'utilisateur d'appuyer le distributeur rechargeable sur la tige de soupape S1 , afin que du produit fluide issu du flacon source S ne remonte dans la chambre intermédiaire I puis à travers les canaux 43 jusque dans le réservoir R dont le volume augmente. L'augmentation du volume du réservoir R peut être engendrée uniquement par la poussée exercée par l'utilisateur sur le flacon source. Elle peut également être assistée par le ressort 5. Sur la figure 5, le distributeur est représenté avec le réservoir R rempli à moitié.  In order to refill the reservoir R, the user can arrange the filling valve 7 on the valve stem S1 of a source bottle S, as shown in FIG. 5. It is then sufficient for the user to press the refillable dispenser on the valve stem S1, so that the fluid from the source bottle S goes up in the intermediate chamber I and through the channels 43 into the tank R whose volume increases. The increase in the volume of the tank R can be generated solely by the thrust exerted by the user on the source flask. It can also be assisted by the spring 5. In Figure 5, the dispenser is shown with the reservoir R half filled.
La figure 6 représente de manière agrandie le détail A de la figure 5. On peut voir que la tige de soupape S1 est appliquée à l'entrée du clapet de remplissage 7 qui communique directement en aval avec la chambre intermédiaire I. La force axiale F exercée vers le bas par l'utilisateur vers le flacon source S permet d'ouvrir le clapet de remplissage 7 et d'enfoncer l'organe coulissant 3 à l'intérieur de l'étui 1 en direction de l'organe de distribution D. Ceci a pour effet d'augmenter le volume du réservoir R dans lequel est générée une dépression qui a pour effet d'aspirer le produit fluide issu de la tige de soupape S1 à travers le clapet de remplissage ouvert 7, la chambre intermédiaire I dont le volume croît, et les canaux 43 qui relient la chambre intermédiaire I au réservoir R. Le remplissage du réservoir R peut être effectué par la seule force axiale F exercée par l'utilisateur. Lorsqu'un ressort 5 est mis en œuvre, celui-ci participe également au remplissage du réservoir R en sollicitant l'organe coulissant 3 vers sa position enfoncée initiale. L'utilisateur peut appuyer le distributeur rechargeable sur le flacon source S jusqu'à ce que le réservoir R soit à nouveau rempli, comme représenté sur la figure 1 . Lorsque l'opération de remplissage est finie, le capot 8 peut être remis en place. FIG. 6 is an enlarged view of the detail A of FIG. 5. It can be seen that the valve stem S1 is applied to the inlet of the filling valve 7 which communicates directly downstream with the intermediate chamber I. The axial force F exerted downwards by the user towards the source bottle S makes it possible to open the filling valve 7 and to push the sliding member 3 inside the case 1 in the direction of the dispensing member D. This has the effect of increasing the volume of the tank R in which a vacuum is generated which has the effect of sucking the fluid product from the valve stem S1 through the open filling valve 7, the intermediate chamber I whose volume increases, and the channels 43 which connect the intermediate chamber I to the tank R. The filling of the tank R can be performed by the single axial force F exerted by the user. When a spring 5 is implemented, it also participates in filling the tank R by urging the sliding member 3 to its depressed position initial. The user can press the refillable dispenser onto the source bottle S until the reservoir R is refilled again, as shown in Figure 1. When the filling operation is finished, the cover 8 can be replaced.
Comme susmentionné, le capot 8 est une pièce optionnelle, mais elle permet cependant de masquer le déplacement de l'organe coulissant 3, de fournir une indication visuelle de l'état de remplissage du réservoir R et de permettre un accès facile au clapet de remplissage 7 une fois retiré.  As mentioned above, the cover 8 is an optional part, but it nevertheless makes it possible to mask the displacement of the sliding member 3, to provide a visual indication of the filling state of the tank R and to allow easy access to the filling valve 7 once removed.
Le ressort 5 est également une pièce optionnelle lorsque l'organe de distribution D est une pompe, mais s'avère essentiel lorsque l'organe de distribution D est une valve ou un clapet de distribution. Le ressort 5 permet une distribution continue du produit fluide, à la manière d'un aérosol.  The spring 5 is also an optional part when the dispensing member D is a pump, but is essential when the dispensing member D is a valve or a dispensing valve. The spring 5 allows a continuous distribution of the fluid product, in the manner of an aerosol.
Il est possible d'optimiser le taux de restitution du distributeur en réduisant la section de la chambre intermédiaire I par rapport à celle du réservoir R.  It is possible to optimize the refund rate of the dispenser by reducing the cross section of the intermediate chamber I relative to that of the reservoir R.
Le piston mobile 35 coulisse ici directement en contact étanche contre la paroi externe du tube plongeur 23, mais on peut envisager un mode de réalisation dans lequel le piston mobile 35 coulisse contre une pièce qui entoure le tube plongeur, qui serait par exemple reliée directement à l'entrée E de l'organe de distribution D.  The mobile piston 35 slides here directly in sealing contact against the outer wall of the dip tube 23, but it is possible to envisage an embodiment in which the movable piston 35 slides against a part which surrounds the dip tube, which would for example be directly connected to the input E of the distribution member D.
L'étui 1 masque presque totalement l'organe coulissant 3 lorsque le réservoir R est rempli : cependant, on peut imaginer une forme de réalisation dans lequel l'étui 1 ne masque que très partiellement l'organe coulissant 3. De même, l'étui 1 présente une forme cylindrique circulaire, mais n'importe quelle forme géométrique ou non est possible.  The case 1 almost completely masks the sliding member 3 when the reservoir R is filled: however, one can imagine an embodiment in which the case 1 only partially masks the sliding member 3. Similarly, Case 1 has a circular cylindrical shape, but any geometric shape or not is possible.
Grâce à la présente invention, on dispose d'un distributeur rechargeable dont le remplissage de réservoir s'effectue très simplement en poussant ou pressant le distributeur rechargeable sur la tige de soupape d'un flacon source. Le réservoir est rempli lorsque le distributeur rechargeable ne peut plus être déplacé par rapport au flacon source.  Thanks to the present invention, there is a refillable dispenser whose tank filling is carried out very simply by pushing or pressing the refillable dispenser on the valve stem of a source bottle. The reservoir is filled when the refillable dispenser can no longer be moved relative to the source bottle.
Il faut également noter que l'assemblage ou le montage de ce distributeur est extrêmement simple, étant donné que toutes les pièces constitutives sont de révolution et ne nécessitent aucune orientation angulaire. Les pièces peuvent être assemblées axialement les unes après les autres dans l'ordre représenté sur la figure 2. Concernant le récipient, l'insert 2 est engagé par le bas dans l'étui 1 , puis l'organe coulissant 3 est introduit par le bas dans l'étui 1 , suivi par le manchon fixe 4 qui vient d'engager autour du tube plongeur 23, puis le ressort 5 est engagé autour de la gaine 41 , suivi par le support de clapet 6 qui vient en prise fixe à l'intérieur de l'organe coulissant 3 avec sa tubulure 63 qui vient se loger à l'intérieur du ressort 5 autour de la gaine 41 . Puis le clapet de remplissage 7 est engagé à l'intérieur de son logement de réception 62. Finalement, le capot 8 peut être mis en place en bas de l'étui 1 . Il suffit alors de monter la tête de distribution T sur le récipient, suivi par le capuchon de protection C. En résumé, on peut dire que l'organe coulissant 3 est engagé autour du tube plongeur 23, suivi par le manchon fixe 4 qui est fixé sur le tube plongeur 23, puis enfin le support de clapet 6 fixé à l'intérieur de l'organe coulissant 3. Comme susmentionné, le ressort 5 est une pièce intermédiaire optionnelle. It should also be noted that the assembly or assembly of this dispenser is extremely simple, since all the parts constitutive elements are of revolution and do not require any angular orientation. The parts can be assembled axially one after the other in the order shown in FIG. 2. With regard to the container, the insert 2 is engaged from below in the case 1, then the sliding member 3 is introduced by the bottom in the case 1, followed by the fixed sleeve 4 which has just engaged around the dip tube 23, then the spring 5 is engaged around the sheath 41, followed by the valve support 6 which engages with the inside the sliding member 3 with its tubing 63 which is housed inside the spring 5 around the sheath 41. Then the filling valve 7 is engaged inside its receiving housing 62. Finally, the cover 8 can be put in place at the bottom of the case 1. It is then sufficient to mount the dispensing head T on the container, followed by the protective cap C. In summary, it can be said that the sliding member 3 is engaged around the dip tube 23, followed by the fixed sleeve 4 which is fixed on the dip tube 23, then finally the valve support 6 fixed inside the sliding member 3. As mentioned above, the spring 5 is an optional intermediate piece.
