Description

The invention relates to a liquid refilling system for a bottle.

It is known that vials containing liquid and which are equipped with a pump are very difficult or impossible to refill when the vial is empty or almost empty and the user wants to keep it.

Indeed, conventionally, the pumps are mounted on the bottles in such a way that disassembly is impossible, or in any case very difficult, without damaging the pumps and / or bottles.

It would therefore be useful to design a system for refilling a vial equipped with a pump without the need to remove the pump and without questioning the actual design of vials on the market.

• au moins un premier flacon S contenant du liquide et comprenant un fond à une extrémité et une ouverture pour la sortie du liquide du flacon à une extrémité opposée,
• au moins un deuxième flacon R à re-remplir avec le liquide du premier flacon S, le deuxième flacon comprenant un fond à une extrémité et une pompe montée sur le flacon à une extrémité opposée, la pompe étant équipée d'au moins un orifice de mise à l'air libre qui est apte à être ouvert ou fermé selon la position de la pompe, le deuxième flacon R étant en position retournée avec la pompe située en dessous du fond dudit flacon,
• une interface de remplissage reliant les deux flacons, l'interface comprenant, d'une part, au moins un passage de liquide disposé entre les deux flacons pour le transfert du liquide sous pression, du premier flacon S au deuxième flacon retourné R à travers ledit au moins un orifice de mise à l'air libre ouvert de la pompe dudit deuxième flacon et, d'autre part, au moins un passage de gaz pour l'évacuation du gaz contenu dans le deuxième flacon retourné R vers l'extérieur dudit flacon.

The subject of the present invention is thus a liquid refilling system for a bottle, characterized in that it comprises:

The system according to the invention makes it possible, from an action, for example external (temporary or permanent) on the system, to refill in a simple and effective manner a bottle from another so-called source bottle without having to dismount. the pump of the bottle to refill. The system does not require to design a specific bottle to be able to refill it. Indeed, this system allows the contrary to use conventional bottles (at least a portion of the standard bottles of the market). The system plans to return the bottle to be refilled and use its pump in the depressed position to introduce inside this bottle of pressurized liquid from the source bottle and passing through a filling interface. The filling interface fluidly connects the flasks. The liquid can be pressurized in different ways: the pressurization can come from an injection of gas for example point in the source bottle, the opening of the source bottle in which a pressurized gas exerts a permanent pressure on the liquid, an external action of pumping the liquid contained in the source bottle in order to transfer it under pressure into the interface ...

The opening of said at least one first bottle (source bottle) can be located above the bottom thereof (normal position of the bottle with the head up) or below the bottom (position returned with the head down) .

• au moins un premier flacon S contenant du liquide et comprenant un fond à une extrémité et une ouverture pour la sortie du liquide du flacon à une extrémité opposée, l'ouverture étant située au-dessus du fond ou en dessous selon le mode de réalisation,
• au moins un deuxième flacon R à re-remplir avec le liquide du premier flacon S (ledit au moins un deuxième flacon, vide ou presque vide, a déjà été utilisé pour distribuer du liquide tel qu'une fragrance ou parfum qui a été consommé et doit être rempli à nouveau), le deuxième flacon comprenant un fond à une extrémité et une pompe montée sur le flacon (de manière non nécessairement démontable) à une extrémité opposée, la pompe étant équipée d'au moins un orifice de mise à l'air libre qui est apte à être ouvert ou fermé selon la position de la pompe (enfoncée ou non enfoncée, c'est-à-dire au repos), le deuxième flacon R étant en position retournée avec la pompe située en dessous du fond dudit flacon,

The invention which is described below with reference to the accompanying drawings relates in particular to a system for refilling a vial and a related method. The system generally includes:

• at least one first S-bottle containing liquid and comprising a bottom at one end and an opening for the liquid outlet of the vial at an opposite end, the opening being above or below the bottom depending on the embodiment,
• at least one second bottle R to be refilled with the liquid of the first bottle S (said at least one second bottle, empty or almost empty, has already been used to dispense liquid such as a fragrance or perfume which has been consumed and must be refilled), the second vial comprising a bottom at one end and a pump mounted on the vial (not necessarily removable) at an opposite end, the pump being equipped with at least one setting port. free air which is able to be opened or closed according to the position of the pump (depressed or not depressed, that is to say at rest), the second bottle R being in the inverted position with the pump located below the bottom of said bottle,
• a filling interface connecting the two bottles. The interface comprises, on the one hand, at least one liquid passage disposed between the two vials for the transfer of the pressurized liquid, from the first bottle S to the second inverted bottle R, through said at least one dispensing orifice. 'air open free of the pump of said second bottle and, secondly, at least one gas passage such as air for the evacuation of gas such as the air contained in the second flask returned R outwardly of said flask (It should be noted that the gas contained in the flask may be an inert gas such as nitrogen). In the absence of action on the system (action such as mechanical stress, pressure ... from a user or an external device) the transfer of liquid does not intervene between the two bottles . As will be seen later, the filling interface may be very simple to design and mainly comprise ducts forming passages for the passage of liquid between the flasks and for the passage of gas (eg air) from the flask to be refilled. outwards.

It will be noted that the system described above may comprise one or more first bottles S (bottle (s) source (s)) and one or more second bottles R (bottle (s) to be refilled) according to the intended applications. In the following, for the sake of simplification the system is described with a single first bottle (first type) and a single second bottle (second type) but the description also applies to several bottles of the same type.

In the cases described above, the interface is adapted to cooperate with several bottles.

It will also be noted that the R and S flasks are conventional flasks in the sense that they have not been developed specifically to form part of the system according to the invention. Only the filling interface and its elements / moving parts, accessories, etc. have been developed specifically for the system functions.

The system described above can take different forms and, for example, it can be configured with a first source bottle S located below and a second bottle returned to refill R located above the first bottle, with the interface between the two (first configuration of the Figures 1a to 10b ). Alternatively, the system can be configured with a first source bottle S located next to a second flask returned to re-fill R (second configuration of figures 11a-b ), the bottom of the second inverted flask may be arranged at a lower dimension than that of the first flask ( figure 11a ) or greater than first bottle ( figure 11b ). According to another alternative related to the second configuration, the system can be configured with a first source bottle S returned and located next to a second bottle returned to refill R (configuration of Figures 12a-b ). The two bottles being arranged next to each other, the filling interface is disposed wholly or partly between the two bottles, or even next to the two bottles or above or below the two or one of only two. Other configurations not shown are of course conceivable.

It should be noted that one of the bottles or all the bottles may be inclined relative to the vertical, since the degree of inclination does not affect the operation of the refilling system.

The foregoing description and, in particular, the configurations set out above also apply to Figures 13a and 13b which are schematic.

According to the first configuration, several embodiments can be envisaged ( Figures 1a-c , 9 and 10a-b ).

The figure 1a illustrates a system 10 according to a first embodiment wherein the interface I is intended to be fixed to the lower bottle S and the top flask returned R. These three elements are separable from each other.

As shown, the second bottle R comprises a pump R12 mounted here non-releasably on the bottle, via a crimping capsule C, at the open end Ra of said bottle which is opposite the bottom Rb located at the bottom of the bottle. opposite end closed. According to a variant not shown, the pump is removably mounted on the bottle.

Conventionally, the pump R12 comprises a fixed part (body) R14 which is introduced through the opening Ra defined inside the neck Rc of the bottle. The fixed part R14 is fixedly mounted on the bottle thanks to the crimping cap C fixed around the neck Rc. The fixed portion R14 extends partly outside the bottle to cooperate with the capsule for example by a shoulder and partly inside the bottle where it is extended by a dip tube or suction tube T fixed to the fixed part.

The pump R12 comprises, inside the fixed part R14, a movable part (piston) R16 which is able to slide axially along the internal face of the fixed part, while ensuring a tight contact between the two parts during of this relative movement. The mobile part R16 comprises a first internal portion R16a mounted on a return spring R18 which is supported on the inner face of the bottom F of the fixed portion R14. The mobile part R16 also comprises a second portion R16b which extends, on the one hand, partly inside the fixed part and, on the other hand, partly outside (through the capsule C). in order to be operated from outside the bottle as will be explained below. The second portion R16b is mounted to bear on the first internal portion R16a via a return spring R19. This second portion R16b is an elongate piece which has a generally hollow stem shape. It will be noted that the mobile part R16 can be in one piece.

When the bottle is conventionally used a pusher not shown is generally mounted around the protruding portion of the second portion R16b in order to actuate the rod (by depression) and thus the pump from a rest position (not depressed ) such as Figures 1a-b . This makes it possible to dispense liquid in a conventional manner from the bottle R when it contains liquid.

The fixed part R14 comprises a wall R14a which is pierced with one or more holes of which only one R14b is represented on the Fig. 1a . This or these holes allow to put in communication a chamber internal to the pump with the inside of the bottle when the first internal portion R16a moves towards the inner face of the bottom F of the fixed part, under the action of depression of the rod R16b, and releases the hole or holes R14b ( Fig. 1 C ).

The bottom F of the fixed portion R14 is configured to include a valve system comprising a ball b housed in a cage c and a valve seat s arranged in said bottom F and which is pierced with an opening communicating with the inside the tube T. The tube T is embedded in a chimney R14c extending axially from the outer face of the bottom F of the fixed part R14 and away from this face towards the bottom Rb of the bottle. The cage c extends axially from the inner face of the bottom F of the fixed part R14 and away from this face, inside the fixed part. The return spring R18 is arranged around the cage. The cage c is perforated laterally and may, for example, be made from several separate elements spaced from each other. The height of the cage is adjusted so that the ball b can move axially away from the valve seat s and thus bring into communication the inside of the tube T and the inside of the fixed part R14. The ball b, however, remains trapped inside the cage c by the distal end thereof which is narrower than its base to stop the movement of the ball.

The wall R14a of the fixed part R14 has a shoulder R14d around which the capsule C is mounted.

The second portion R16b comprises, in its part which extends inside the fixed part R14, a flange R16b1 located at the outer periphery of the second portion so as to be held in abutment against the internal face of the capsule C when the pump is not depressed ( figs 1a and 1b ), under the action of the springs R18 and R19.

The second portion R16b comprises, in its part which extends outside the fixed part R14 and the capsule C (beyond the flange R16b1), a diameter shrinkage R16b2 near its distal end. This narrowing of diameter R16b2 makes it possible to create one or more orifices O for venting between this narrowing and an inner peripheral edge Ci delimiting the central opening of the capsule C and which is crossed by the second portion R16b when the second portion R16b is pressed inside the fixed part R14 ( Fig. 1 C ). In this depressed position of the pump, the outside of the bottle communicates with the inside of the fixed part R14 of the pump via the orifice or openings O for venting (orifice (s) open (s)) and with the inside of the bottle via the hole or holes R14b released from the wall of the pump. This arrangement thus creates a passage internal to the bottle (especially internal to the pump) for the passage of the outside air compensation in the conventional use of the bottle. However, in the present embodiment this passage is used to convey liquid from the bottle S, then from the interface I to the inside of the bottle R.

It should be noted that other pump configurations may be contemplated with different arrangements for communicating the outside of the vial with the interior thereof via one or more venting ports.

A piece R20 forming a pump cover is mounted around the capsule C and the neck of the bottle Rc generally by clamping and is open axially at its two opposite ends so as to be able, by a proximal end R20a, to be threaded onto the capsule and, by its distal opposite end R20b, leave free access to the second portion R16b and a space between the part R20 and the portion of the capsule C surrounding the second portion R16b. It will be noted that the distal end R20b is provided with an internal peripheral rim or return r ( Figs. 1a and 1b ) directed towards the part of the capsule surrounding the second portion R16b.

In this embodiment, the bottle S has the same pump structures, crimping capsule and pump cover part as the bottle R as described above, although this is not an obligation. For example, the bottle S may comprise another type of pump and / or crimping cap and / or pumphead piece, or even crimping cap or pump cover piece or just one of them.

The interface I comprises a structure I10 in which are arranged internal passages or channels passing through the structure and used to circulate liquid (passage (s) P1), air (passage (s) P2) or a gas (passage (s) P3) according to the passage (s) or channels concerned.

The structure I10 is configured to accommodate a plurality of movable parts or attachment parts for mechanical attachment of the interface on each of the bottles R and S and the attachment of these parts together (however, in other embodiments the parts or attachment parts of the mobile interface or not are not necessarily hooked together), as well as contact parts with the protruding portion of the second portion R16b of each pump R12 to operate the pump by depression. The contact parts also perform the function of seal with the relevant bottle.

• des organes d'accrochage I12a, I14a (ex : pattes d'accrochage) tournés vers l'extérieur de la structure et qui servent à coopérer avec un ou des éléments d'accrochage complémentaires de chaque flacon afin de fixer la structure de l'interface au flacon concerné en poussant la structure vers le flacon ou inversement ; dans cet exemple, l'élément d'accrochage est formé par le rebord périphérique interne r de l'extrémité distale R20b sur la fig. 1b et vient s'insérer dans une gorge externe d'un organe d'accrochage ; on obtient ainsi une première position d'accrochage de l'interface aux flacons sur la figure 1b mais qui n'est toutefois pas encore opérationnelle car la pompe n'a pas encore été actionnée ;
• des organes d'accrochage I12b, I14b tournés vers l'intérieur de la structure et qui servent à coopérer par engagement avec les organes d'accrochage complémentaires de l'autre partie ou pièce d'accrochage ; l'engagement des deux parties ou pièces d'accrochage I12, I14 entre elles est illustré sur la figure 1c.

The reception structure I10 comprises at each of its two opposite axial ends I10a, I10b a movable part or hanging part I12, I14 with respect to the interface and which is each provided with fastening members of two types:

• fastening members I12a, I14a (eg catching tabs) facing outwardly of the structure and serving to cooperate with one or more complementary fastening elements of each bottle in order to fix the structure of the interface to the bottle concerned by pushing the structure towards the bottle or vice versa; in this example, the hooking element is formed by the inner peripheral rim r of the distal end R20b on the Fig. 1b and is inserted into an external groove of a fastening member; thus obtaining a first attachment position of the interface to the bottles on the figure 1b but which is not yet operational because the pump has not yet been actuated;
• fastening members I12b, I14b turned towards the inside of the structure and which serve to cooperate by engagement with the complementary fastening members of the other part or attachment piece; the engagement of the two parts or fasteners I12, I14 between them is illustrated on the figure 1c .

Note that the two parts or attachment pieces I12, I14 are each housed in a peripheral space having a height or axial dimension (taken along the alignment direction of the bottles and the interface, this direction being here confused with the vertical axis) which allows each attachment part to slide axially towards the other part from the position of the Figures 1a-b . In this position the two parts I12, I14 are arranged at the ends I10a and I10b and are held there in spaced apart position on the one hand, thanks to elastic members I16a, I16b (ex: springs of return) mounted between these parts and an inner support surface of the structure and, on the other hand, thanks to one or more internal returns I10a1 ( Fig. 1b ). Each attachment portion I12, I14 has a substantially annular shape and has on each of its two opposite faces the hooking members of the two types described above. When the two gripping parts I12, I14 are axially displaced one towards the other under the action of an external axial force (eg: bringing a bottle closer to each other and / or bringing the two bottles closer towards each other), the elastic members I16a, I16b are compressed until the engagement or hooking of the two attachment members I12b, I14b complementary, each of which for example each have a retaining lug shape (second operational latching position of the Fig. 1 C ). This makes it possible to immobilize the two attachment parts I12, I14 with respect to one another in a second hooking position.

As shown on Figures 1a-c , the structure I10 of the interface comprises a central block I22 located between the two attachment portions I12, I14 and which comprises at least a portion of each of the passages P1 to P3. The block I22 comprises an axial through-cavity I22a located at the periphery of the block and in which at least a portion of the internal fasteners I12b, I14b extend, so as to allow their axial displacement under an external action and their connection ( Figs. 1b and 1c ).

The structure I10 also comprises two parts I18, I20 of contact with the protruding part (outer) of the second portion R16b of each pump R12. Each piece I18, I20 is disposed between an end I10a, I10b of the structure and the central block I22, in a central region (near the longitudinal axis, here vertical, of the structure) which is surrounded by the attachment part corresponding device I12 or I14. Each piece I18, I20 is installed in a central housing delimited externally by an axial wall I22b, I22c (ex: cylindrical) which extends from the central block I22. Each piece I18, I20 is made of a material less rigid than the rest of the structure I10 so as to be elastically deformed under axial stress and form a seal. Each part I18, I20 comprises in its central part a channel I18e, I20e provided, at one end facing the block I22, a lip seal I18a I20a which, in the absence of air pressure internal to the interface (pressure higher than ambient outside pressure), is closed (non-return valve). Each piece I18, I20 also comprises an annular protrusion I18b, I20b which extends axially from the face of the part which is opposite the block I22, in a part of this face which surrounds the central part with the channel. This growth ring I18b, I20b crushes in contact with the capsule C ( Fig. 1 C ), thus ensuring a sealing function. Each piece I18, I20 has, on the opposite side side to that bearing the annular protrusion, a central cavity 118c, I20c in which the seal I18a, I20a extends. The central block I22 comprises one or more projecting elements I22d, I22e, which are intended to support the bottom of each cavity, next to the seal I18a, I20a. Each piece I18, I20 also comprises a passage portion I18d, I20d for the routing of the liquid for the part I18 and the gas flow for the part I20. Each passage portion I18d, I20d constitutes a portion of the passage P1 and the passage P3 respectively, the other parts of the passages P1 and P3 being integrated in the block I22. The passage P2 is also integrated in the block I22. The piece I18, I20 also comprises, at the end of the channel I18e, I20e opposite that where the lip seal I18a I20a, a housing I18f, I20f whose width corresponds to the diameter of the shrinkage R16b2 of the rod R16b.

• on dispose d'abord le premier flacon S en position normale (pompe R12 au dessus du fond Rb), éventuellement sur un support 30, puis on amène l'interface I au dessus du flacon S, de manière à ce que les organes d'accrochage I14a soient en face de l'ouverture axiale de la pièce cache-pompe R20, notamment du rebord interne r (fig. 1a) ; dans cette position, la partie saillante rétrécie R16b2 de la tige R16b est disposée en vis-à-vis du logement I20f aménagé à l'entrée du canal I20e ;
• on amène, au dessus de l'interface I, le deuxième flacon R (à re-remplir) en position retournée avec la pompe R12 située en dessous du fond Rb dudit flacon, de manière à ce que les organes d'accrochage I12a soient en face de l'ouverture axiale de la pièce cache-pompe R20, notamment du rebord r (fig. 1a) ; dans cette position, la partie saillante rétrécie R16b2 de la tige R16b est disposée en vis-à-vis du logement I18f aménagé à l'entrée du canal I18e ;
• on rapproche les trois pièces R, S, I l'une de l'autre dans l'axe d'alignement de celles-ci (en exerçant un effort axial selon la flèche F, ici verticale, de poussée ou appui sur le fond de l'un ou des deux flacons, selon que le flacon S repose sur le support 30 ou non) afin de les emboîter deux par deux grâce aux organes d'accrochage I12a et I14a engagés respectivement avec le rebord r de chaque pièce R20 et retenus axialement dans cette position (fig. 1b) : l'interface I est ainsi fixée/accrochée aux deux flacons dans une première position d'accrochage (la partie saillante rétrécie R16b2 de chaque tige R16b2 est engagée dans son logement correspondant I20f, I18f) ;

• on continue à exercer un effort axial ou appui (pression externe exercée par exemple par un utilisateur) selon la flèche F, ici verticale, de poussée sur le fond du flacon R (le flacon S étant en appui sur le support 30) de manière à comprimer les ressorts 116a, I16b afin de faire coulisser les deux parties d'accrochage I12 et I14 dans leurs espaces périphériques/logements en direction l'une de l'autre, permettant ainsi d'engager les organes I12b et I14b l'un avec l'autre (fig. 1c) ; lors de ce déplacement axial les parties saillantes rétrécies R16b2 des tiges R16b2 s'enfoncent dans leurs logements correspondants I20f, I18f, viennent en butée sur le fond, puis reculent à l'intérieur de la partie fixe R14 de chaque pompe en comprimant les ressorts R18 et R19 afin de dégager le ou les trous R14b et d'ouvrir/créer le ou les orifices de mise à l'air libre O comme expliqué plus haut . Simultanément, lors de ce déplacement les extensions axiales I22b et I22c coulissent le long des organes d'accrochage I12a et I14a respectivement (fig. 1c), à l'intérieur de ceux-ci, afin de venir se loger entre ces derniers et la capsule C, interdisant ainsi toute déformation radiale vers l'intérieur desdits organes d'accrochage. Cet agencement permet de verrouiller l'interface I dans sa position fixée à chaque flacon (deuxième position d'accrochage verrouillée). On notera à titre de variante non représentée qu'un ou plusieurs éléments de blocage/verrouillage de l'interface peuvent alternativement remplacer les axiales I22b et I22c dans le but de maintenir les organes d'accrochage crochetés sur le rebord interne r.

The Figures 1a to 1c illustrate different assembly steps of the system 10 from the two bottles R and S and the interface I:

• the first bottle S is firstly placed in the normal position (pump R12 above the bottom Rb), possibly on a support 30, then the interface I is brought to the top of the bottle S, so that the organs of I14a hook are opposite the axial opening of the pump-protector piece R20, in particular the internal r-rim ( Fig. 1a ); in this position, the narrowed projecting portion R16b2 of the rod R16b is disposed opposite the housing I20f arranged at the inlet of the channel I20e;
• is brought, above the interface I, the second bottle R (to be refilled) in the inverted position with the pump R12 located below the bottom Rb of said bottle, so that the attachment members I12a are in face of the axial opening of the pump-protector piece R20, in particular the flange r ( Fig. 1a ); in this position, the narrowed projecting portion R16b2 of the rod R16b is disposed opposite the housing I18f arranged at the entrance of the channel I18e;
• the three pieces R, S, I are brought closer to one another in the alignment axis thereof (exerting an axial force according to the arrow F, here vertical, pushing or resting on the bottom of one or both bottles, depending on whether the bottle S rests on the support 30 or not) in order to fit two by two through the shackles I12a and I14a engaged respectively with the edge r of each piece R20 and retained axially in this position ( Fig. 1b ): the interface I is thus fixed / hooked to the two bottles in a first hooking position (the narrowed projecting portion R16b2 of each rod R16b2 is engaged in its corresponding housing I20f, I18f);

• it continues to exert an axial force or pressure (external pressure exerted for example by a user) according to the arrow F, here vertical, thrust on the bottom of the bottle R (the bottle S being supported on the support 30) so as to compressing the springs 116a, I16b so as to slide the two attachment portions I12 and I14 into their peripheral spaces / housings towards each other, thus making it possible to engage the members I12b and I14b, one with the other ( Fig. 1 C ); during this axial displacement the narrowed projections R16b2 of the rods R16b2 sink into their corresponding housing I20f, I18f, abut on the bottom, then retreat inside the fixed part R14 of each pump by compressing the springs R18 and R19 to clear the hole (s) R14b and to open / create the vent hole (s) O as explained above. Simultaneously, during this displacement, the axial extensions I22b and I22c slide along the fastening members I12a and I14a respectively ( Fig. 1 C ), inside of them, in order to be housed between them and the capsule C, thus preventing any radial deformation inward of said fastening members. This arrangement makes it possible to lock the interface I in its position fixed to each bottle (second locked latching position). Note as a variant not shown that one or more blocking elements / locking of the interface can alternatively replace the axial I22b and I22c in order to keep the hooked hooking members on the inner r r.

In this second hooking position the two bottles are each fixed to the filling interface by keeping the pump of each bottle pressed into the bottle (orifice (s) venting O open (s)) and the passage normally intended for outdoor open compensation air.

In the embodiment shown, an overpressure is created in the bottle S by injection of a gas under pressure (arrow G) in the interface I via the passage / channel P3 ( Fig. 1 C ), then in the bottle S through the orifice O, the hole R14b, the opening Ra of the neck and the inside of the bottle as indicated by the arrows. The liquid L present in the bottle is thus subjected to the overpressure of gas, which causes its rise in the tube T, the lifting of the ball b above the seat s, the crossing of the valve by the liquid, the rise of the liquid inside the rod R16b, through the lip seal I20a open under the pressure of the liquid, the internal cavity located behind and the vertical passage P1 (integrated passage portion I22 block and I18d portion), then through the orifice O of the bottle R, the hole R14b, the opening Ra of the neck and the inside of said bottle R. The liquid thus leaves the source bottle S and is transferred, via the filling interface I, to the flask returned R to fill it again.

The liquid injected under pressure into the bottle R fills the latter from the neck. The liquid level rises and the internal air is expelled by the tube T, as indicated by the arrows, then travels through the valve which opens under the pressure of the air, the inside of the rod R16b, the channel and the lip seal 18a which opens under the pressure of the air, then the passage P2 before exiting the interface. A piece A of absorbent material such as a ring is placed around the structure of the interface, at the outlet of the passage P2 (alternatively, the piece is placed against the face where the outlet of the passage P2 is arranged) in order to absorb a possible liquid flow that may occur after all the air from the bottle R has been discharged to the outside and that the liquid level has exceeded the upper end of the tube T. This piece A is also useful when the pump n ' has not been previously purged.

It should be noted that the gas is, for example, injected at a pressure of between 0.1 and 2 bar, for example 0.5 bar. This gas is generally a gas that does not alter the composition of the liquid L such as air or a known inert gas (eg nitrogen). Means for injecting gas under pressure will be described later with reference to figures 7a-b , 8a-b .

Note that a deactivation element B (ex: deactivation finger) is positioned, through the outer wall of the structure I to level of an organ, namely for example the organ I14b. A thrust on the deactivating element B makes it possible to deform the organ I14b of the organ I12b by deformation and, thus, to release the organs I12b and I14b engaged with each other. Under the action of the springs I16a and I16b the attachment portions I12 and I14 deviate axially from one another to return to the intermediate position of the figure 1b . The interface is always attached to the bottles but no longer in a locked position.

The Figures 2a to 6c which will be described below are examples of simplified implementation of a filling interface between two bottles with a multiplication of efforts to provide.

The Figures 2a to 2c illustrate a first possible example of a mechanism allowing a simplified implementation, on at least one of the two bottles R and S, of a filling interface I 'similar to that of the Figures 1a-c . The following description relates only to the attachment of the interface to the inverted flask R, knowing that the same mechanism is duplicated for attachment to the lower bottle S not shown. All the illustrated references on the Figures 1a-c are not repeated here for the sake of clarity but apply with the exception of the hooking parts I12 and I14 and their hooking between them which no longer takes place. The shape of these parts has indeed been modified and the springs I16a, I16b have been removed.

The interface I 'comprises a central block I'22 incorporating at least a portion of the passages P1 to P3, an elastomer contact piece 1'18 similar to the piece I18, surrounded by an axial extension 1'22b but which has no no lip seal (however, in a variant not shown, this part may include a seal such as I18a). The interface comprises a space or peripheral housing E 'surrounding the I'18 piece and in which is positioned the attachment portion I'12 equipped with its shackles 1'12a. The attachment portion I'12 has an annular shape delimited at its outer periphery by an axial wall or axial elements I'12b which are provided on their outer face of teeth. The interface also comprises at least one lever, for example here two diametrically opposed levers I'30 mounted articulated about an axis I'30a perpendicular to the alignment axis of the interface and the bottle R, on the outer wall I'32 of the structure I 'delimiting externally the space E '. Each lever I'30 (or single lever) has a head I'30b surrounding the axis I'30a and an arm I'30c. The head is provided, on its outer surface perpendicular to the axis I'30a, with teeth (such as a pinion) meshing with the teeth of the outer face of the axial wall or axial elements I'12b, to through an opening in the outer wall 1'32 of the structure I '.

On the figure 2a the levers I'30 are in a lowered position along the outer wall I'32 and in engagement with one or more teeth of the axial wall or axial elements I'12b. The interface I 'and the bottle are close to one another and the attachment members 12a (resilient tabs) deform elastically in contact with the rim r of the pump-retaining piece R20 to cross the opening delimited by the outer edge of the capsule C and this flange and engage with said flange in the retained position (hooked) on the figure 2b .

The interface is thus fixed to the bottle R in a first attachment position which is not yet the locked operational position. We do the same with the lower bottle S not shown.

The Figure 2c illustrates the next step in which levers I'30 are raised (rotation of 180 ° about their pivot axis I'30a), which causes the gripping portion I'12 to slide downwards by meshing of the teeth of the levers and teeth of the axial wall or of the axial elements I'12b. The hooking portion 1'12 being attached to the piece R20 integral with the bottle R, the latter is driven downwardly with the engaging portion 1'12 (or the interface is driven upwards towards the vial), thereby bringing the contact member 1'18 into contact with the tapered protrusion R16b2 of the rod R16b. This movement makes it possible to depress / actuate the pump by disengaging the hole or holes R14b and by opening / creating the venting orifice (s) O as explained above. As described with reference to Figures 1a-c simultaneously with this movement, the axial extension 1'22b is inserted between the hooking members I'12a and the capsule C to lock the members in position and therefore the interface on the bottle. The hooking members I'12a are thus locked on the bottle via the piece R20. In this way, a second hooking position is obtained for the locked interface to the bottle in which the pump is maintained actuated (permanently). The procedure is the same with the lower bottle S not shown. The system is made operational, ready to transfer pressurized liquid from the bottle S to the bottle R under the action of a gas injection under pressure. Lever means (s) described (lever (s) controlled by a gear) and its (their) implementation allows (thanks to a force reduction effect) any user can easily operate the pump of each bottle (the supply of the pump in the lowered or depressed position generally requires a force of the order of 3 to 4 kg or more) and to obtain the seal with the I'18 piece forming a seal. The levers I'30 are in the locking and unlocking position arranged along the interface, which does not cause any external space likely to hinder the user. The procedure is the same with the lower bottle S not shown.

The operation of the system thus set up is identical to that described for the embodiment of the Figures 1a-c and will not be repeated here.

It will be noted that the unlocking of the interface with respect to the bottle is done in an inverse manner by lowering the levers I'30 and bringing them back to the position of the figure 2a .

The Figures 3a and 3b illustrate a possible variant of the mechanism for simplified implementation of Figures 2a to 2c . The mechanism of Figures 3a-b uses a gearless lever system.

• la partie d'accrochage I"12 est montée sur un ressort I"16a (ou tout autre organe élastique assurant la même fonction) et est susceptible de coulisser axialement dans l'espace périphérique E" aménagé au dessus du bloc central I"22;
• deux leviers ou bras I"30 sont encastrés par leur tête I"30b qui est montée à pivotement autour de l'axe I"30a entre ladite partie d'accrochage I"12 et une pièce d'appui supérieur I"32 fixée au bloc central I"22 (la pièce d'appui pourrait être d'un seul tenant avec le bloc dans une variante) ; chaque levier est solidaire de la partie d'accrochage I"12 par l'intermédiaire de son axe I"30a et est apte à pivoter autour de l'axe par rapport à ladite partie I"12 ; la tête de chaque levier présente une face externe dont une partie est courbe à son extrémité. A titre de variante non représentée, un seul levier peut être envisagé.

The system of Figures 3a-b differs from that of Figures 2a-c by the following elements of the interface I ":

• the attachment portion I "12 is mounted on a spring I" 16a (or any other elastic member providing the same function) and is capable of sliding axially in the peripheral space E "arranged above the central block I"22;
• two levers or arms I "30 are recessed by their head I" 30b which is pivotally mounted about the axis I "30a between said attachment portion I" 12 and an upper support piece I "32 fixed to the block central I "22 (the support piece could be in one piece with the block in a variant); each lever is secured to the attachment portion I "12 via its I axis "30a and is rotatable about the axis with respect to said portion I"12; the head of each lever has an outer face, a portion of which is curved at its end. As a variant not shown, a single lever can be considered.

In the position of the figure 3a the two levers I "30 are in the horizontal standby position while the interface I" is fixed to the inverted bottle R as already described in FIGS. Figures 2a-c (first hanging position). In this position the outer face of the head I "30b of each lever is in abutment against the underside of the upper support piece I" 32.

To lock the interface to the bottle in a simple manner and without undue effort (in order to actuate / depress the pump), the user grasps the two levers I "30 and pivots them downwards (in the manner of movement of the arms of a corkscrew) as shown in figure 3b (the effort to be exerted by the user is multiplied). During this movement, the head I "30b of each lever rests against the lower face of the upper support piece I" 32, thus exerting a leverage effect thereon. By thus supporting the lever lowers and thus translates the attachment portion I "12 which compresses the spring I" 16a. As the attachment portion I "12 is attached to the bottle, this movement induces a relative movement between the bottle and the interface, in particular the central block I" 22. As for the other modes, the axial extension I "22b ensures the locking in position of the interface by keeping the gripping members pressed against the rim R. The actuation of the pump is carried out as already described with reference to FIGS. Figures 2a-c . The levers I "30 are in the locking position arranged along the interface, which does not cause any external space likely to hinder the user.The same is the same with the lower bottle S not shown.

The operation of the system thus set up is identical to that described for the embodiment of the Figures 1a-c and will not be repeated here.

It will be noted that the unlocking of the interface with respect to the bottle is carried out inversely by raising the levers I "30 to bring them back to the position of the figure 3a .

The Figures 4a to 4d illustrate a second possible example of a simplified implementation mechanism, on at least one of the two bottles R and S, of a filling interface I '"similar to that of the Figures 1a-c .

The bottle R 'has the same elements as the bottle R with the exception of the capsule C and the pump-cover piece which are absent (it could however have a capsule set in a variant not shown, or even a pump cover adapted ). The rod R'16b is held inside the fixed part R'14 by a not shown retaining element. The pump is also held in the bottle by a retaining element not shown.

The interface I "'has a structure comprising the central block I"' 22 integrating the passages P1 to P3 not completely represented here. The structure extends on either side of the block by an annular wall I "'32 delimiting an internal space E'" (only the upper wall is shown here).

A contact and sealing piece I '"18 similar to the piece I18 of Figures 1a-c is disposed in the center of the space E '"in a housing delimited externally by an axial cylindrical extension I"' 22b of the block. The contact and sealing piece I "'18 is hollow and bears in its central part on a support I"' 22c enclosing a compression spring I "'22d.

Exhibit I "'18 is pierced, on the one hand, at the center by an I-channel" 18 ^e aligned with the spring I "22d and with the inlet passage and P2, on the other hand, in periphery by a channel I '"18d which is part of the passage P1.

The annular wall I '"32 is provided on its internal face turned towards the internal space E'" of an internal thread I "'32a.

An intermediate piece B10 having a generally annular shape is provided on its outer face with a thread B10a complementary to the thread I '"32 for its attachment to the interface, the piece B10 is a part or part of attachment that is movable relative to the interface and whose role is to hang the interface to the bottle.

Part B10 has an inner face configured to house a single piece or a plurality of circumferentially spaced pieces each made of soft (flexible) and adherent material B12. For convenience, in the rest of the presentation it will be a question of a ring adhesion B12. The material exerting the adhesion function is for example an elastomer or a foam.

The part B10 comprises a continuous low part B10b throughout its circumference and an upper part B10c which is not continuous over its entire circumference so as to form a plurality of portions spaced from one another along the circumference.

The figure 4b represents in plan view the intermediate part B10 with upper portions B10i regularly spaced along the circumference of the part and mounted on a common annular support B10j visible between the portions B10i. These portions B10i form elastic tabs which, in the rest position ( Fig. 4a ), are flared outward. In this figure, the common annular support B10j is screwed partially inside the wall I "32 of the interface in order to hold the piece B10 alone.

The adhesion ring B12 comprises several pieces B12i spaced circumferentially on the figure 4b and fixed firmly, for example by gluing, to the inner faces of portions B10i. B12i pieces form adhesion pads.

As shown on the figure 4a , the bottle R 'is disposed above the intermediate part B10 mechanically engaged in the interface. The bottle is moved downward along the arrow F1 (translation) in the direction of the part B10 so that the neck R'c of the bottle comes into contact with its outer face (ex: here by its outer shoulder) with the adhesion ring B12, more particularly its pads B12i. The adhesion of the neck with the pads makes it possible to immobilize the bottle relative to the intermediate piece B10. The user then rotates the bottle according to the arrow F2 in order to screw said part B10 (driven in rotation by adhesion) inside the interface, in the space E ''. When screwing the thread B10a to the In the interior of the thread I "'32a, the portions B10i carrying the adhesion pads B12i are tightened radially in the direction of the center of the piece B10 and therefore of the neck R'c. The adhesion pads B12i made of a soft material deform around the neck R'c, while the piece B10 and the bottle down to the central block I '"22. The piston R'16b (hollow rod) retracts to inside the fixed part R'14 and compresses the springs R'18 and R'19 when the end of the part Tightened protrusion R'16b2 is engaged in the channel I "18e and is under the action of the spring I '" 22d (note that this spring or any other elastic member can absorb any axial dimension variations). The hole R'14b is thus released and the vent hole O 'is created. This orifice is here formed by the annular space surrounding the piston and delimited externally by the shoulder R'14d of the wall R'14a. The aforementioned arrangement does not cause any external dimensions that may interfere with the user. The same procedure is followed with the lower bottle S (not shown) which, in this example, does not (optionally) have a cap and a pump-cap piece.

The operation of the system thus set up is identical to that described for the embodiment of the Figures 1a-c and will not be repeated here.

The attachment of the interface to the bottle is performed differently with a reduced effort (axial depression and screwing). The attachment does not involve two latching positions as above but only one position which is the locked latching position ( Fig. 4d ). The attachment of the interface to the bottle uses one or more gestures to which the user is accustomed, which makes handling particularly easy. This embodiment makes it possible to fix, at a filling interface, vials without a pump-protector piece.

It will be noted that the unlocking of the interface with respect to the flasks is carried out inversely by unscrewing each flask in order to return successively to the positions of the flasks. Figures 4c and 4a .

The figures 5a-d illustrate a first possible variant of the system of Figures 4a-d for fixing an interface I "" to a top flask R "" This bottle is almost identical to the bottle R of Figures 1a-c with the exception of two diametrically opposite zones R "d on its outer surface which are configured to facilitate the gripping of the bottle by the fingers of a user.These areas R" d here correspond to indentations (or imprints) but could be grooved areas, textured otherwise than grooves ...... in addition or alternately with the recesses. The bottle R "comprises a crimping capsule C and a pump-retaining piece R20.

The interface I "" comprises an intermediate part or piece I "" 12 (mobile with respect to the interface) which combines the attachment functions of the parts I12 and I'12 of the Figures 1a to 3b and intermediate piece B10 Figures 4a-d with its function of adhesion (adhesion ring / adhesion pads).

The intermediate attachment part I "" 12 comprises fastening members I "" 12a identical to the attachment members I12a ( figs 1a-c ) and which are intended to snap on the inner r of the R20 r part.

The intermediate attachment piece I "" 12 shown separately in plan view at the figure 5a has upper portions B'10i regularly spaced along the circumference of the part and mounted on a common annular support B'10j visible between the portions B'10i. These portions B'10i form elastic tabs which, in the rest position ( Figs. 5a-b ), are flared outward. On the figure 5b the common annular support B'10j provided with a thread B'10h on the outside is partially screwed inside the wall I "" 32 of the interface (threaded on its inner face with a complementary thread I "" 32a ) in a waiting position.

The adhesion ring comprises several B'12i pieces circumferentially spaced on the figure 5a and secured, for example by gluing, to the inner faces of the portions B'10i. B'12i pieces form adhesion pads made for example in the same material as the system of the Figures 4a-d . Unlike the system of Figures 4a-d , pads B'12i have axial grooves B'12j relative to the axis of revolution of the piece I "" 12. These grooves are arranged along the axis of insertion of the bottle (axis of the arrow F1 on the figure 5b ) to facilitate the translation insertion of the bottle. As for the system of Figures 4a-d each pair of pads and portion B'10i could be a single piece integral with the common annular support B'10j.

The common annular support B'10j comprises, on its inner face, the attachment members I "" 12a respectively arranged in radial correspondence with the pads B'12i. A radial space is provided between these attachment members I "" 12a and the axial grooves B'12j of the pads to enable the passage of the inner rim r of the capsule ( Fig. 5c ). It will be noted that the sealing piece I "" 18 is identical to the piece I'18 of the Figures 2a-c .

As shown on Figures 5b to 5d , the user inserts axially downward along the arrow F1 the bottle R 'between the pads B'12i of the intermediate attachment piece I "" 12 (the user may or may not grasp the bottle by the zones R "d) to bring the pump seal part R20 into contact with the adherent material constituting the pads B'12i and to insert the internal flange r into the external groove of the fastening members I "" 12a (first attachment position of the figure 5c ). In this position the part R20 is in axial abutment on the intermediate attachment part I "" 12 via the fastening members. The user grasps the bottle with the fingers pressed into the two zones or fingerprints R "d to rotate (according to the arrow F2) the bottle adhering to the intermediate attachment part I""12 (rotational connection of the two elements ) and thus screwing the latter inside the interface I "". During the screwing, the portions B'10i provided with pads B'12i (flexible tabs) are tightened radially on the part R20 and the intermediate piece of I "" hooking "12 descends into the open peripheral space of the interface, while the axial extension I""22b of the interface is inserted into the radial space between the attachment members I""12a and the capsule C ( Fig. 5d ) to prevent any radial deformation of said members under the action of screwing which has just been described. This arrangement thus makes it possible to lock the inside of the flexible tabs I "" 22b on the part R20 (and therefore of the interface on the bottle) while keeping the pump actuated (position depressed or low when the bottle is in the normal position). The figure 5d illustrates the locked position of the system from which the bottle R "can be refilled again (since the interface has also been fixed identically to the lower bottle S not shown).

The operation of the system thus set up is identical to that described for the embodiment of the Figures 1a-c and will not be repeated here.

It will be noted that the unlocking of the interface with respect to the flasks is carried out inversely by unscrewing each flask in order to return successively to the positions of the flasks. Figures 5c and 5b .

The Figures 6a-c illustrate a second possible variant of the system of Figures 4a-d for fixing an interface I ""'to a top flask returned R identical to the bottle R of Figures 1a-c . The system of Figures 6a-c has no adhering material but a fastening piece I "" 12 whose base I ""'12b is identical to the common annular support B'10j of the figure 5b and comprises fastening members I '"" 12a and an external thread I "" 12c cooperating with the internal thread I "" 32a of the wall I "" 32.

However, the attachment piece I '"" 12 movable relative to the interface is extended axially upwards by an axial extension I ""' 12d which projects in particular beyond the interface and which is provided on the outer surface of its upper free end of two diametrically opposite zones I '"" 12e which are configured to facilitate the grip of the part by the fingers of a user.

These zones I "" 12e here correspond to recesses (or imprints) in the end which is thicker than the rest of the extension. However, it could be grooved areas, textured otherwise than by grooves ...... in addition or alternately with the recesses. The axial extension I '"" 12d of the attachment piece I' "" 12 defines an upper axial inner housing at the bottom of which are arranged the attachment members I '"" 12a. The diameter of this housing can accommodate the R bottle.

The axial extension I '"" 12d has on its outer surface two unhooked d1, d2 offset axially and radially relative to each other. The first hook d1 allows the attachment piece I '"" 12 to go down into the peripheral space E'"" without mechanically interfering with the internal thread I "" 32a ( Fig. 6c ).

The second stall d2 allows the attachment piece I "" '12 to descend into the peripheral space E' "" while being guided by the inner surface of the wall I "" 32.

In the position of the figure 6a , the attachment piece I ""'12 is partially screwed inside the wall I "" 32 of the interface (on the upper part of the thread I ""' 32a, in the standby position.

As shown on Figures 6a to 6c , the user inserts axially downward along the arrow F1 the bottle R in the upper axial inner housing ( Fig. 6a ) of the attachment piece I "" 12 to insert the internal rim r of the capsule in the outer groove of the fastening members I '"" 12a located at the bottom of the housing (first attachment position of the figure 6b ). In this position the part R20 is in axial abutment on the intermediate attachment piece I '"" 12 via the attachment members I'"" 12a and is immobilized in translation thereon. The user grasps the axial extension I ""'12d (sheath) with the fingers pressed into the two zones or fingerprints I'"" 12e and presses it while spinning (according to the arrow F2 of the figure 6b ) the intermediate attachment piece I "" 12, which has the effect of screwing it inside the wall I ""'32 of the interface I ""', thus causing the bottle in translation downhill in the space E '"". Simultaneously, the axial extension I "" 22b of the interface engages between the attachment members I '"" 12a and the capsule C to prevent any radial displacement / deformation of said members towards the capsule in order to disengage from the inner rim r. At the end of screwing the piece I '"" 32 is at the bottom of the space E'"", the pump is actuated (depressed or low position when the bottle is in the normal position) and the shackles I '"" 12a (flexible tabs) are locked in the latching position.

The Figure 6c illustrates the locked position of the system from which the bottle R can be refilled (since the interface has also been fixed and locked identically to the lower bottle S not shown).

The operation of the system thus set up is identical to that described for the embodiment of the Figures 1a-c and will not be repeated here.

It will be noted that the unlocking of the interface with respect to the flasks is carried out inversely by unscrewing each flask in order to return successively to the positions of the flasks. figures 6b and 5a .

The system of Figures 6a-c is useful when grease is present on the R20 pump cover. In such a situation, the system of figures 5a-d is less efficient because the adhesion necessary for the rotation of the bottle is more difficult to obtain. The system of Figures 6a-c circumvents this difficulty since the screwing force is no longer exerted directly on the pump-retaining piece R20 or on the body of the bottle (the user is no longer in direct contact with the bottle) but on a part intermediate hooked to the inner rim of the pump-protector piece R20 (the intermediate attachment piece I '"" 12 is removable relative to the interface, as in the embodiments of the Figures 2a-c , 4a-d and 5a-d ). Thus, even if the outer surface of the body of the bottle is oily, the establishment of the system takes place with great efficiency.

It should be noted that the contact and sealing piece I "" 18 (identical to the piece I "" 18 of the Figures 5b-d ) performs two functions where the system of Figures 4a-d requires two pieces: the contact and sealing piece I "'18 and the spring I"'22d. Exhibit I ""'18 ( Fig. 6c ) comprises a downward axial portion forming a skirt I '"" 18f which is supported by adjusting on the central support I ""' 22c of the interface, thus allowing to absorb / compensate any variations in the rating of parts (pump ...).

For the sake of simplicity, the features and advantages of each system which has been described above for the first time have not been systematically repeated in the description of the following systems incorporating all or part of this system. Of course, these features and advantages also apply to the following systems except in the case of technical incompatibility.

It will be noted that the filling interface of the various modes and variants described above may comprise different shapes and therefore different parts and attachment mechanisms for fixing the inverted bottle and for that of the source bottle, for example for adapt to different types of flasks. The parts and mechanisms of attachment of Figures 1a to 6c can thus be interchanged and used in the same interface: an interface (not shown may include a part or mobile attachment part of a first type for hooking the interface to a first bottle and a part or part d mobile hooking of a second type for attaching the interface to a second bottle, thus the lever or levers of the Figures 3a-b are arranged in the upper part of the interface in order to cover when they are in the folded-down position ( fig 3b ), the levers of the Figure 2c arranged in the lower part of the interface. Such an arrangement provides an unlocking order between the vials. By way of example, the interface may alternatively comprise an intermediate hooking part with one or more levers in its upper or lower part and an intermediate hooking part which screws into the interface in the other part.

The figures 7a-b and 8a-b illustrate in axial section two possible examples of a device for injecting pressurized gas capable of cooperating with any one of the interfaces of the preceding figures and FIG. figures 13a-c .

The device for injecting gas under pressure (here, it is about air) 50 ( figures 7a-b ) comprises a casing 52 made of an elastically deformable material (eg pear) which is pierced in an area of its wall with a vent hole 54. The device comprises in another zone of the wall a piece rigid or tip 56 which extends away from the casing and comprises an internal distribution duct 58. The duct 58 has a first end opening into the interior of the casing and a second opposite end opening out of the the envelope. The conduit 58 thus communicates the inside and the outside of the envelope. At rest, the envelope is maintained in its expanded form of the figure 7a the pressure balance being established between the inside and the outside of the envelope.

This device is for example used with the refilling system 10 Figures 1a-c when the latter is operational ( Fig. 1 C ). The tip 56 is approached from the inlet port P3a of the gas passage P3 of the interface and the end 58b of the duct is engaged in this orifice or positioned thereon. The user places his finger on the hole 54 to plug the hole 54 and presses on the envelope 52 to expel through the conduit 58 of the nozzle of the air contained in the envelope as indicated by the arrow G. This pressurized air is introduced inside the passage P3 to fulfill the function described above: conveying air under pressure via the passage P3 to the first bottle S to cause the transfer of pressurized liquid from said bottle to to the second bottle R to be refilled via the interface.

When the user withdraws his finger from the hole 54, the injection of pressurized air ceases immediately (release of the residual air pressure in the bottle S), thus stopping the filling of the inverted bottle R, without however being accompanied by any inertia phenomenon in the system (the air continuing to relax and the liquid under pressure continuing to rise from the bottle S to the bottle R ...). This injection device is therefore particularly effective since it allows to precisely adjust (only by plugging and releasing the hole 54 in a suitable manner) the volume of liquid to be transferred from the bottle S to the bottle R.

• une pompe à air électrique 64,
• un interrupteur 66 monté sur la pompe,
• un contacteur 68 traversant la paroi de l'enveloppe de manière à faire saillie à l'extérieur par une partie, la partie restante étant retenue dans l'enveloppe et montée sur un organe élastique 70 (ex : lame à ressort) qui, en l'absence d'appui sur le contacteur, maintient celui-ci contre la face interne de la paroi de l'enveloppe (fig. 8a),
• un embout 72 disposé dans l'alignement de la pompe et fixé à cette dernière.

The device for injecting gas under pressure (here, it is about air) 60 ( figures 8a-b ) comprises a rigid casing 62 comprising a plurality of air passages 62a in its outer wall and enclosing:

• an electric air pump 64,
• a switch 66 mounted on the pump,
• a contactor 68 passing through the wall of the casing so as to project outwardly by a part, the remaining part being retained in the casing and mounted on an elastic member 70 (eg spring leaf) which, in absence of support on the contactor, keeps it against the inner face of the wall of the envelope ( Fig. 8a )
• a tip 72 disposed in alignment with the pump and fixed thereto.

The envelope 62 is for example in two parts which are assembled together by means of a fastener (eg screwing) placed in the hole 62b ( Fig. 8a ).

The nozzle comprises an axial central duct 74 communicating, on the one hand, with the inside of the pump 64 to receive the compressed air when the pump is actuated and, on the other hand, with the outside of the device for expel this compressed air to the outside.

The tip 72 also comprises a lateral channel 76 extending from the lateral central duct towards the inside of the casing, more particularly in the direction of the elastic member 70 and a sealing and elasticity element. 70a worn by the latter. Element 70a is suitable for be elastically deformed by compression under the action of an external stress and then resume its original shape when the stress ceases.

This device is for example used with the refilling system 10 Figures 1a-c when the latter is operational ( Fig. 1 C ). The tip 72 is approached from the inlet port P3a of the gas passage P3 of the interface and the outlet end 72a of the nozzle is positioned against the latter so as to axially match the duct 74 and the passage P3. The user presses with his finger on the switch 68 which is lowered ( figure 8b ) and comes into contact with the switch 66 of engagement of the pump 64 while compressing and plating the element 70a of the elastic member 70 against the opening opening of the lateral channel 76, thus obstructing the latter. The compressed air by the pump is forced to take the conduit 74 to exit the nozzle 72 and enter the passage P3 of the figure 1c to fulfill the function described above and recalled with reference to figures 7a-b .

When the user removes his finger from the contactor 68, the latter goes back to the position of the figure 8a , the elastic member 70 rises under the action of recovery of the element 70a and the pump 64 stops working. The injection of air under pressure therefore stops immediately (release of the residual air pressure in the bottle S), thus stopping the filling of the inverted bottle R, without being accompanied by any phenomenon of inertia in the system. (the air continues to relax and the liquid under pressure continues to rise from the bottle S to the bottle R ...). The air of the bottle S escapes from the latter via the passage P3 that it rises and then borrows the conduit 74 of the nozzle and the lateral channel 76 to escape into the envelope which is open to the outside . This injection device is therefore particularly effective since it allows precise adjustment (only by plugging and releasing the hole 54 in a suitable manner) the volume of liquid to be transferred from the bottle S to the bottle

The figure 9 illustrates a system 100 for refilling a vial according to a second embodiment of the invention in which the system is still in its first configuration as described above: a first bottle S 'is located below and a second flask returned R is located above the first bottle, with the filling interface 102 disposed between the two.

In this mode, the second inverted bottle R is always equipped with a pump and the interface is fixed to the bottle R so as to keep the pump pressed into said bottle and said at least one venting port of the open pump. The first bottle S 'containing liquid L has no pump unlike the first mode. The bottle S 'is open at its upper end bounded by an outer neck Surrounding the opening S'b.

The returned bottle R is for example identical to that of Figures 1a-c .

The filling interface 102 comprises a central block 104 and, on either side of it, two upper and lower portions 106 respectively 108 in contact with the upper flask returned to refill R and the lower bottle source S . The upper part 106 is fixed to the upper flask returned via a part or mobile attachment part identical to the part I'12 of Figures 2a-c .

The central block 104 integrates almost all the passages P'1, P'2 and P'3 similar to the passages P1, P2 and P3 respectively. Figures 1a-c .

The upper part 106 of the interface comprises a part or attachment piece 110 comprising attachment members 110a carried by the inner periphery of an annular base 110b which is housed in a peripheral space open to the outside. The annular base 110b has at its outer periphery a cylindrical wall 110c provided with an external thread on its outer face to cooperate with the toothed heads of the two levers 111 (alternatively, a single lever can be used). As for the 1'12 piece, the attachment of the part 110 is on the inner r r of the pump-protector piece R20 via the bodies 110a. It will be noted that for all the previous embodiments and variants which have illustrated and describes this mode of attachment the attachment to a bottle of a fastening piece which is connected (removably or not) to the interface can to be carried out differently on the pump cover, the capsule or directly on the bottle, through other complementary hooking elements (not shown here) arranged on the bottle or reported thereon. The attachment piece 110 surrounds a contact and sealing piece 112 identical to the piece I'18 of Figures 2a-c .

On the figure 9 , the interface is in the hooked and locked position of the Figure 2c : the levers are in the raised position and the axial extension or locking element 104a (identical to the element I'22b of the Figure 2c ) is embedded between the members 110a and the outer edge of the capsule C.

The lower part 108 of the interface is, for its part, simplified because of the absence of a pump in the bottle S '.

The portion 108 comprises a skirt 108a provided with an internal thread cooperating with the external thread of the neck S'a. The part 108 also comprises a nozzle 108b disposed in correspondence with the liquid passage P'1 and in which is mounted, through the opening S'b, a dip tube T 'similar to the tube T of the bottle R. A seal sealing 108c is positioned between the upper edge of the neck S'a and the underside of the central block 104.

The passage P'3 conveying gas under pressure opens directly into the opening S'b.

In this embodiment, the piece 110 of the interface is fixed and locked to the bottle as indicated above (here by simple snapping) so as to directly actuate the pump permanently (depression of the pump and opening of the orifice As soon as the interface is firmly fixed in a tight manner to the bottle R and the bottle S ', pressurized gas G can be injected into the passage P'3 via the one of the features of Figures 7a-8b . the gas (eg air) is brought inside the bottle S 'via the opening S'b, pressurizes the liquid to transfer to the bottle R. The pressurized liquid rises in the tube T', the passage P'1, the passage portion included in the piece 112, the vent hole O, the hole R14b and the inside of the bottle R for filling. The air from the bottle R is expelled as already explained above by the tube T, the pump open and the passage P'3. Room A of the figure 1c or a part of the same function can also be provided here at the output of the passage P'2, as also in the other modes and previous or future variants.

This system is particularly suitable for source bottles which can be opened (withdrawal of the pump) without damaging the bottle.

It should be noted that the inverted bottle R can alternatively take any of the different forms of the preceding figures and the upper part of the filling interface can also take any one of the different shapes illustrated in FIGS. Figures 1a-c , 3a-b , 4a-d , 5a-d and 6a-c .

The Figures 10a-b illustrate a system for refilling a bottle according to a third embodiment of the invention in which the system is still in its first configuration as described above: a first bottle S "is located below and a second R flask with a pump is located above the first flask, with the filling interface 150 disposed between the two.

This system is simplified in the sense that the interface 150 is fixed to the two bottles so as to allow relative movement between the bottle S "and the interface 150 along the alignment direction of said bottles and the interface (here the vertical axis), under an external action (ex: pressing or manual pressure or not) exerted in this direction.This external action is exerted for example by the finger of a user to implement the system when desired. The figure 10a corresponds to a waiting position.

The lower source bottle S "is provided with a valve closing the opening of said bottle and contains in this bottle liquid and a gas G 'stored under pressure .The gas G' (under excess pressure) is for example air or an inert gas so as not to alter the composition of the liquid L. This gas is introduced in a conventional manner prior to the use of the bottle as is done for example for a deodorant atomizer, insecticide, lacquer

The valve is able to open under the effect of an axial external action. As shown on the figure 10b (Valve in open position), the valve comprises for example a valve body S "c mounted in a sealed manner in the upper opening of the bottle and a valve member S" v mounted on a spring S "r. external force (which is the case on the figure 10a ) the spring S "r holds the valve member S" v against its valve seat S "s disposed above and formed by the upper inner face of the valve body, thus closing any outlet passage of the liquid of the bottle. S "c is extended in its lower part not a dip tube t which extends near the bottom of the bottle.

The interface 150 comprises a central block 152 incorporating all or part of the liquid transfer passages P "1 of the bottle S" to the inverted flask R and P "2 of the return flask R. The flask R is for example identical to that of Figures 1a-c . However, here there is no pump-cover piece, thus leaving the collar Rc visible ( fig.10a ).

The interface 150 comprises at one of its two opposite ends hooking members 154 which for example snap around the outer groove g located at the base of the neck Rc of the bottle R and grip it with the function retaining the end ends of the fastening members 154. During this attachment, given the length of the members 154, the upper face of the interface is depressed the pump of the bottle R as already described above. In the position of Figures 10a-b the interface is fixed to the bottle R so that the pump of the bottle is pressed permanently (pump pre-pressed) as for the mode of the figure 9 .

The interface 150 comprises at the other opposite end an open end whose dimensions allow to cap the projecting end of the valve of the bottle S ".

In the waiting position of the figure 10a the valve is closed and the gas is kept under pressure in a sealed manner in the bottle S ".

When the user wishes, he presses on the bottom of the flask turned R with his finger as indicated by the downward vertical arrow of the figure 10b . This external action has the effect of exerting a downward (axial) vertical pressure on the valve of the lower bottle S ", which compresses the spring S" r, removes the valve member S "v from its valve seat S" s and opens the passage to the liquid under pressure of the bottle. The liquid maintained under the pressure of the gas is forced to mount in the tube t, the body S "c, the valve member S" v, then to flow in the passage P "1 of the interface in order to join the vent hole, the pump and the inside of the inverted flask R.

The opening of the bottle S "allows the transfer of the liquid from the first bottle S" to the second flask returned R as a result of the release of the pressure of the internal gas G 'residing permanently in the bottle S ".

The filling of the inverted flask R is thus carried out and the air inside said flask is evacuated by the plunger tube, the pump and the passage P "2 as already explained above.The process of transferring liquid under pressure can be interrupted. on command when the support of the finger of the user ceases, which has the effect of raising the interface and the bottle R attached thereto, thus closing the valve of the bottle S "and now stored again the gas G under reduced pressure.

The external action on the system can thus be exerted repeatedly over time.

According to a variant not shown, the filling interface is fixed to the top flask returned without the pump being depressed. It is then pressed only when the user presses the inverted bottle ( Fig.10B ) to simultaneously open the valve of the bottle S ".

As illustrated on figures 11a and 11b , a refilling system of a bottle according to one embodiment of the invention can be configured with a first bottle located next to a second flask returned (second configuration) and not one below the another in an axial configuration. The bottom of the second inverted flask may be arranged at a lower dimension than that of the first flask ( figure 11a ) or greater than that of the first bottle ( figure 11b ), or even the same dimension (not shown).

The figure 11a represents a system configuration 200 of refilling a flask R1 returned with a source bottle S1 (fourth mode). The flasks are interconnected by a filling interface 210 which includes a flexible conduit 212 extending between the two flasks.

The source bottle S1 is equipped with a pump R12 as the bottle S of Figures 1a-c , a capsule C and a pump-cover piece R20, as well as a dip tube T immersed in the liquid contained in this bottle.

The source bottle S1 takes all the characteristics of the bottle S and further comprises a pusher S10, for example conventional, which caps the upper end of the bottle. For example, the pusher comprises a skirt S10a which is inserted in the annular space disposed between the capsule C and the pump-retaining piece R20. The pusher covers the projecting end of the second portion R16b (hollow piston rod) by its central portion S10b which contains an internal channel S10c matched to the inside of the piston R16b and which leaves on the side of the pusher. The pusher S10 also comprises at the outlet of the channel a protruding projecting end S10b on which is fixed an end of the duct 212.

The conduit 212 is fixed at its opposite end to an interface portion 214 to which is releasably attached the returned bottle to refill R1.

This bottle has the same characteristics as those of the bottle R ' Figures 4a-d and S1 bottle (pump, dip tube ... but no capsule or pump cover piece).

In the example shown, the bottle R1 is for example smaller than the source bottle S1, although it is by no means an obligation.

The system 200 includes an interface portion 214 that is identical to the upper portion of the interface I '" Figures 4a-d in that it comprises a hollow body open at its upper part to receive, on the one hand, in its central part a contact and sealing member 216 identical to the piece I '"18 and secondly about an intermediate annular attachment piece 218, identical to the part B10, around the part 216. This part 218 is provided at its outer periphery with an external thread 218a cooperating with a complementary internal thread 214a of a cylindrical wall 214b delimiting externally the recess of the body of the interface.This piece 218 is provided at its inner periphery with pads 218b made of, for example, elastomeric material identical to the pads B12. Bottle R1 via the part 218 makes it possible to fix and lock the interface to the bottle so as to keep the pump of the bottle pressed permanently.

The interface portion 214 comprises a base or base 220 in which are integrated a passage P '"1 for the supply of pressurized liquid to the pump of the flask R1 and a passage P'" 2 for the evacuation of the air of the flask R1 under the action of filling said flask with the liquid transferred under pressure from the flask S1.

The interface 210 here comprises the flexible conduit 212 and the interface portion 214.

In the example shown a part of the system 200 is housed in a housing or box 230 comprising an open hollow body which is closed by a cover 234 unsealed. Through openings are provided in the cover for the passage of the bottles S1 and R1 and the flexible conduit 212. An upper portion of each of the bottles S1 and R1 and the conduit 212 protrudes here above the hood. However, the height of the vertical walls of the housing can be different and especially larger, thus hiding all or part of the body of the bottles and, for example, leaving only the pusher S10 and the upper end of the conduit 212. The openings are adapted to the external dimensions of the flasks and the duct to facilitate their insertion from above. In particular, the bottle R1 is easily installed in the interface portion 214 by simply translating said bottle vertically through the corresponding opening in the cover 234. In this example, the source bottle S1 is larger and heavier than the bottle. R1 can be simply placed on the bottom of the box without being fixed. In a variant not shown, it can however be attached to the bottom or to another part of the housing.

The implementation of the system 200 thus installed is particularly easy since it is sufficient for the user to press the pusher S10 successively, as indicated by the vertical arrow, to suck liquid by pumping (creating a vacuum ) in the tube, then to transfer the pressurized liquid through the pump, the pusher, the conduit 212, the passage P '"1, the pump of the bottle R1 and the inside thereof. the latter is evacuated via the pump and the passage P '"2 as the liquid is transferred. When the user stops pressing, the pusher and the pump up, interrupting the transfer of liquid by suctioning liquid by pumping. The filling of the bottle R1 is therefore particularly simple and accurate.

During successive presses of the user on the pusher S10, a vertical translation movement between the two bottles is performed. The stroke of the pusher is absorbed by the flexibility of the conduit 212.

Note that the base 220 of the interface portion 214 is for example made in one piece with the bottom 232a of the body 232. However, according to a variant not shown, the interface portion 214 can be dissociated from the bottom.

It should be noted that the latching portion of the interface portion 214 may differ from that shown and take for example one of the forms of Figures 5a to 6c . The bottles S1 and R1 may also differ and may or may not include a pump cover and / or a capsule depending on the applications envisaged and the types of bottle.

The figure 11b illustrates a fifth embodiment of a system 300 for refilling an inverted flask R2 with a source flask S2. This system is very close to the system 200 but differs in that the source flask S2 is arranged at a lower rating than that of the flask R2 returned.

The system is partially housed inside a body 332 of a housing or box 330 closed by a cover 334 not waterproof.

An upper opening 334a is made in the cover 334 to enable the inverted flask R2 to be introduced from above and to fix it on the attachment portion 340 of the interface portion 342. The attachment portion 340 is identical to part 218 of the figure 11a and the interface portion 342 includes a pedestal 344 higher than the pedestal 220 to elevate the interface portion 342 and thus the vial R2. The same remarks as those made about the figure 11a also apply here.

The housing is open at its bottom in the bottom 336 and an opening 336a is thus provided to allow to engage the bottle S2 and introduce it inside the housing.

The cover 334 is configured in the form of a pusher, in an area located next to the opening 334a, with on the upper (outer) face of the cover, an actuating member 350. The pusher extends inside the housing by a base 352 which integrates an internal channel 354 similar to the channel S10c of the figure 11a .

A duct 360, for example a flexible duct, similar to the duct 212, connects the interface portion 342 to the open end of the internal duct 354. The base 352 of the plunger has on its underside a housing 352a adapted to receive the end of the hollow rod. R16b of the S2 bottle pump when said bottle is introduced inside the housing through the lower opening 336a.

In the position of the figure 11b , the user has only to successively press the member 350 / releasing the pressure as indicated by the vertical arrow to cause the descent / rise of the housing 330 and thus of the bottle S2 attached thereto and, thus, actuate the S2 bottle pump (pushing in / out of the pump).

As for the mode of figure 11a when the support stops, the transfer of the pressurized liquid is interrupted.

The modes of figures 11a and 11b are easy to implement (for example with one hand) and hide most of the mechanisms of the systems through a housing in which are arranged housing to receive the bottles, making these modes particularly interesting for some applications. These modes can also be applied to configurations with more than two vials (eg a source vial and two or more vials to refill, or a refill bottle and two or more vials source).

A system 400 for refilling a vial according to a sixth embodiment is illustrated in FIG. figure 12a in the second configuration where the S3 source vials and re-fill R3 are next to each other. Here, the source bottle S3 containing liquid L is also returned and has no dip tube or pump. Both flasks are at approximately the same rating although it is not an obligation.

The source bottle S3 and the bottle to be filled R3 are both mounted on a support or base 402 which serves as a filling interface fluidically and mechanically connecting the bottles. In the example shown, the source bottle has a volume greater than the bottle to refill but it is not an obligation.

The filling interface 402 has on a horizontal upper face 402a two locations E1, E2 horizontally distant from each other and configured to each receive one of the bottles.

The first location E1 is formed by a hollow element E11 for receiving the bottle S3 which projects relative to the upper face 402a. The hollow element E11 has an internal thread E12 in which the external thread S32 of the neck S31 of the bottle S3 is screwed. The element E11 forms a socket which is for example integrated in the interface. The element E11 has for example a hollow cylindrical shape.

The interface 402 comprises a passage 404 for supplying a pressurized gas G from a source of gas that is not shown (the source is part or not of the interface and, more generally of the system). This passage 404 includes a valve or valve 406 formed for example of a ball mounted on a spring and which closes an orifice 404a of the passage in the absence of gas injection into the passage.

This passage 404 opens at the upper face 402a and extends above this face by a chimney 408 which penetrates inside the bushing E11 and the neck S31 when the bottle is screwed into the bushing E11.

The location E2 comprises, integrated in the interface 402, for example above the face 402a, the filling interface I 'illustrated in FIGS. Figures 2a-c with the two levers 1'30 and the attachment portion 1'12 equipped with its hooking 1'12a. This interface I 'is adapted at the level of the gear link of the levers with the part I'12 so that the insertion of the bottle into the interface I' and its locking takes place for a pivoting of the levers at an angle of 90 ° and not 180 ° as on the Figures 2a-c . it suffices to adapt the number of teeth of the gear mechanism.

The interface 402 also includes a passage 410 which extends from a first end flush with the face 402a inside the bushing E11 (and the neck S31 when the bottle is screwed into the bushing E11) to the interface I 'of the location E2. This passage 410 serves for the transfer of liquid from the source bottle S3 flask to be filled R3.

The interface also includes a passage 412 for venting the gas (here air) from the bottle to be refilled R3.

The passages 404, 410 and 412 are here integrated in the body of the filling interface 402 but other possibilities of arrangement can be envisaged.

The operation of the system is very simple since it is the injection of gas under pressure into the passage 404 which increases the pressure inside the source bottle S3 (above the liquid), triggers the transfer of liquid under pressure from the source bottle S3 to the bottle to be refilled R3 and the evacuation of air from the latter to the outside, as indicated by the arrows on the figure 12a . As soon as the gas injection ceases, the transfer of the liquid stops.

The supply of gas (eg air) into the filling interface 402 can be carried out for example by one of the pumping devices illustrated in FIGS. figures 7a-b , 8a-b . The supply of gas may alternatively be effected by other means such as a pressurized gas tank associated with a valve and the assembly being connected to the inlet of the passage 404. The valve may for example be mounted on the reservoir or downstream thereof in a circuit connecting the reservoir to the valve. Such a means for injecting pressurized gas without a pumping device can also be used with the embodiments described above except for the Figures 10a-b .

A system 500 for refilling a vial according to a seventh embodiment is illustrated in FIG. figure 12b in the second configuration where the S4 source vials and re-fill R4 are next to each other. Here, the source bottle S4 containing liquid L is also returned and does not include a dip tube but a pump. This system is identical to that of the figure 11b as regards the bottle to be refilled R4 and will not be detailed again for this part of the system.

As for the system 300, the system 500 is partially housed inside a body 502 of a housing or cabinet 530 closed by a cover 534 not leakproof.

• sur la partie d'accrochage 340 de la partie d'interface 342, pour le flacon R4 (comme sur la figure 11b),
• sur une partie d'accrochage 540 fixée sur le fond fermé 536 du corps 502, pour le flacon S4.

Two upper openings 534a, 534b are made in the cover 534 to enable the two upside-down bottles R4 and S4 to be respectively introduced from above and to fix them inside the body 502:

• on the hooking portion 340 of the interface portion 342, for the R4 flask (as on the figure 11b )
• on a hooking portion 540 fixed on the closed bottom 536 of the body 502, for the bottle S4.

The engaging portion 540 is part of the system fill interface as is the interface portion 342 and includes a base 542 that is lower than the pedestal 344 and includes an internal passage 544 for the liquid. The two bases 344 and 544 are connected to each other by a conduit 546 (conduit for the passage of liquid) which is for example sealingly engaged in force on two respective nozzles 344a and 544a integral with the bases. The base 542 is shown with a shoulder but it is not a necessity.

The passage 544 extends from the nozzle 544a located at one end of the passage to an opposite end which opens on the upper face of the base 542. Note that the nozzle is disposed on one of the sides of the base but it could be willing to another place. The passage 544 forms a bend and thus has in this example a layered L shape.

The source bottle S4 is equipped with a pump 550 mounted here non-releasably on the bottle, via a crimping capsule C (in a variant the pump is removably mounted). A part 552 forming a pump cover is mounted around the capsule and the neck of the bottle. These elements and the entire bottle are identical to those described with reference to Figures 1a-c and will not be further detailed here.

The pump 550 comprises, like the pump R12 Figures 1a-c , a movable part (piston) whose end 554a opening beyond the pump cover 552 is configured to fit into a housing 542a of the base 542. This housing surrounds the open end of the passage 544. Thus, the Inside the piston is in communication with the passage 544.

In the position of the figure 12b , the user (whose finger is visible) has pressed vertically on the bottom of the bottle S4 protruding from the housing 530 to actuate the pump 550 inside the bottle (depression / reassembly of the pump). The piston is thus depressed and the vent or openings open (as the pumps of the two bottles on the Figures 1b and 1c ), which allows the liquid to flow from the source bottle S4 into the passage 544 via the pump. The liquid is thus conveyed under pressure via the conduit 546, to the interface portion 342, then into the bottle to be filled R4 by the same mechanism as that already described. No gas injection is used here.

As for the mode of figure 11b when the support stops on the bottle S4, the bottle rises vertically (according to the arrow) and its pump returns to the non-depressed position, thus closing the passage for the liquid (see the position of the pumps of the figure 1a ). The transfer of the liquid under pressure is interrupted.

The user has only to successively press the bottle / release the pressure as indicated by the double vertical arrow to cause the descent / rise of the bottle and, thus, actuate / release the pump of the bottle S4.

• un flacon source S5 contenant du liquide et qui est disposé à l'endroit (tête du flacon en haut comme pour les modes des figures 1a à 11b ; toutefois, dans une variante non représentée, le flacon source peut être retourné, par exemple comme pour les modes des figures 12a-b) ;
• un flacon à re-remplir R5 qui est en position retournée comme sur toutes les figures précédentes ;
• un dispositif 610 qui est configuré pour délivrer/fournir du gaz sous pression au flacon source S5 ;
• une interface de remplissage 620 qui comprend :
  • un passage de liquide 622 reliant fluidiquement et mécaniquement les deux flacons pour le transfert du liquide sous pression, du flacon S5 au flacon retourné R5 à travers ledit au moins un orifice de mise à l'air libre (non représenté sur la figure) ouvert de la pompe du flacon R5,
  • un passage de gaz 624 pour l'acheminement du gaz sous pression au flacon source,
  • et un passage de gaz (généralement de l'air) 626 pour l'évacuation du gaz contenu dans le flacon à re-remplir lors de l'opération de re-remplissage.

The refilling system 600 of the figure 13a schematically represents:

• a S5 source bottle containing liquid and which is arranged at the place (head of the bottle at the top as for the modes of the Figures 1a to 11b ; however, in a variant not shown, the source bottle can be returned, for example as for the modes of Figures 12a-b );
• a bottle to be filled R5 which is in the inverted position as in all the previous figures;
• a device 610 which is configured to deliver / supply pressurized gas to the source bottle S5;
• a fill interface 620 that includes:
  • a liquid passage 622 fluidically and mechanically connecting the two flasks for the transfer of the pressurized liquid from the S5 flask to the flask returned R5 through said at least one open vent (not shown in the figure) open the pump of the flask R5,
  • a gas passage 624 for conveying the pressurized gas to the source bottle,
  • and a passage of gas (generally air) 626 for evacuation of the gas contained in the bottle to be refilled during the refilling operation.

The device 610 includes a pumping device 612 for pressurizing gas from a gas source (eg tank or ambient air) 614 and a valve 616 connected to the passage 624 (eg via a fitting 624a). The source 614 shown in dotted lines may or may not be part of the device 610. The pumping device 612 is for example of the manual type, for example of the type of the figures 7a-b or of the electric type, for example of the type of figures 8a-b which includes an electric pump. The valve 616 is configured in a first state not open on the outside so as not to interrupt the delivery of pressurized gas in the passage 624 and into the bottle S5 (this gas is pressurized by the pumping device when this last is activated). When the valve 616 is in a second state open to the outside (passage from one state to another controlled manually or electrically), the pressure in the passage 624 and in the source bottle S5 drops and equilibrates with the atmospheric pressure, which interrupts the injection / delivery of pressurized gas into the source bottle S5. Generally, the pumping device 612 has also ceased to function when the valve 616 goes into this second state. The valve is for example a solenoid valve which is electrically controlled.

Actuation of the valve 616 in the second state thus makes it possible to immediately stop the transfer of the pressurized liquid from the source bottle S5 to the bottle to be filled R5 and thus the filling of the latter. In the absence of valve 616, the filling continues even when the pumping device stops working because the compressible air generates a phenomenon of inertia.

The re-filling system 650 of the figure 13b schematically illustrates another embodiment in which the elements of the figure 13a are identical except for device 610.

Indeed, the refilling system 650 comprises a device 660 configured to deliver / supply gas under pressure to the source bottle S5 using a pressurized gas tank 662.

The pressurized gas tank 662 is capable of supplying pressurized gas to the passage 624 and to the source flask S5.

The device 660 comprises a first valve or valve 664 which, depending on its state (manually or electrically controlled), open or closed, allows the delivery of pressurized gas from the tank 662 into the passage 624 and into the source bottle S5 or prevents this routing. This valve can be mounted directly on the tank or remote from it (the valve is for example placed on a pipe connected to the tank and downstream thereof in the direction of flow of the gas, the pipe between the tank 662 and the valve 664 may or may not be part of the gas passage 624) according to the desired configurations. The valve 664 can be manual or electrically controlled.

The device 660 also comprises a second valve which is the valve 616 already described with reference to the figure 13a . When this valve is open (first state), it allows the gas to flow to the source bottle S5 via the passage 624 and, when it is closed (second state), it prevents the supply of pressurized gas to the source bottle S5 via the passage 624.

The second valve 616 is generally open on the outside when the first valve 664 is closed (to abruptly stop the transfer of liquid under pressure between the bottles) and, conversely, it is closed when the first valve 664 is opened (to cause the transfer of pressurized liquid between the vials).

The device 610 ( Fig. 13a ) or 660 ( Fig. 13b ), regardless of its configuration, may or may not be integrated with the system's fill interface. On the figures 7a-b , 8a-b , the device is for example separate from the interface.

On the figure 13c , the device is at least partly integrated with the filling interface.

This figure illustrates a system 700 refilling according to another embodiment of the invention.

This system takes over system 100 from the figure 9 with an S6 source bottle without pump in the head up position, a flask to be filled R6 returned, and a filling interface 702 which comprises, on the one hand, the interface 102 of the figure 9 and, on the other hand, an extension 704 of this interface. This extension 704 accommodates a pumping device 710 comprising an electric pump 712 (for example with air) and a valve 714 which are both mounted connected to the gas passage 716 (as in FIG. figure 13a ) connected to the passage P'3 leading directly to the interior of the bottle S6.

A member 718 for actuating the pump 712 such as an on / off button disposed on an outer face of the interface makes it possible to implement the pump. As soon as the pump 712 is stopped, the valve 714 is automatically open on the outside in order to quickly end the filling (the two members 712 and 714 are for example electrically connected to one another).

The interface 702 also comprises a power supply of the pump and the valve (here a solenoid valve) which is formed of batteries or batteries 720. The connections between the power supply 720 and the elements 712, 714 of the interface are not represented in the cutting plane.

Absorbent material 722 (optional) is disposed on the gas (air) exhaust passage 724 which extends, in the interface extension 704, the passage P'2. This material makes it possible to absorb liquid in the event of an undesired liquid outlet from the flask R6 through the gas evacuation passage.

In the embodiment of the figure 13c the interface extension 704 for example takes the form of a belt surrounding the interface portion 102 and attached thereto. However, the interface 702 could be formed in one piece.

The interface extension can alternatively take another form. It should also be noted that part 102 of the filling interface which welcomes the bottles R6 and S6 may alternatively adopt a different form of that illustrated here, including other means for fixing the bottles.

Furthermore, according to a variant not shown, the interface extension 704 can accommodate instead of the pump 712 a gas tank under pressure (eg air or inert gas) equipped with a valve fulfilling the functions of the valve 664 of the figure 13b .
