    [0001] The present invention relates to a fluid reservoir comprising a neck defining an opening in which a stopper is engaged. This reservoir is intended to be associated with a dispensing member, such as a pump or a valve, to together constitute a fluid dispenser. When mounting the dispenser member on the reservoir, a feed passage must be established to communicate the interior of the tank with the input of the dispenser member. The preferred fields of application of the present invention are those of cosmetics, pharmacy or perfumery, in which the reservoir of the invention can be used as a refill or cartridge. In the prior art, it has long been known fluid containers provided with a plug so as to close the opening of the neck. The term "stopper" should be understood in its widest definition, that is to say encompassing any closing, covering or sealing element able to seal the opening of the neck, in order to preserve the contained fluid product. in the tank any deterioration, contamination or damage. Thus, the plugs of the prior art can be in the form of a plug to be inserted into the neck, a cap to be screwed or snapped around the neck, a cover or a membrane glued to the edge of the neck. opening of the collar. Thus, during assembly of the dispensing member on these tanks, either the cap is removed beforehand, or it is pierced or torn by a member of the dispenser member inserted through the neck. With a cap to unscrew or snap, there is the question of the disposal of this cap which has no function. With membranes or lids to drill or tear, it happens that debris fall into the fluid, which can contaminate or damage the dispenser member. The present invention aims to overcome the aforementioned drawbacks of the prior art by defining a fluid reservoir, for example of the refill or cartridge type, which is equipped with a cap capable of defining a guaranteed feed passage, sized , clean, and that without creating pieces to throw, to drill or debris in the fluid. To do this, the present invention proposes a fluid reservoir comprising a neck defining an opening in which a stopper is engaged, characterized in that the stopper is slidably movable in the neck between a closed top initial position in which the stopper closes. hermetically opening the neck and an open low end position in which at least one feed passage communicates the interior of the tank with the outside. The cap is therefore intended to remain in place in the opening of the neck, the plug moving to create the feed passage. According to an advantageous embodiment, the cap comprises an annular sealing lip which is in sealing contact with the collar in the closed up initial position and which is out of tight contact with the neck in the open low end position, thus defining said at least a feed passage between the stopper and the neck. Thus, this annular sealing lip slides sealingly in the neck over a certain height, then separates from the neck near the low open end position to create the feed passage (s). Advantageously, the plug may comprise an annular guide lip which is in permanent sliding contact with the neck between the two initial and final positions to guide the plug during its displacement in the neck. In other words, the annular guide lip never leaves the contact with the neck during its sliding. However, this annular guide lip does not necessarily guarantee a tight contact over the entire inner periphery of the neck. According to another advantageous aspect of the invention, said at least one feed passage is defined between the two sealing and guiding lips. The feed passage may even extend to the annular guide lip, but may in no case extend to the annular sealing lip. According to a practical embodiment, the two sealing and guiding lips may be formed at two opposite annular edges of a socket, said at least one supply passage extending through the socket. Preferably, the socket forms at least one vertical slot which interrupts the guide lip and defines the feed passage. This slot can extend to near the annular sealing lip without interrupting it. According to another advantageous characteristic of the invention, the plug may comprise a cup which extends downwards from the socket. It can also be said that the bushing defines an upper edge or flange of the bucket.
    [0002] One of the principles of the present invention is to provide the neck of a reservoir with a sliding cap which remains permanently secured to the neck, but which closes it in the upper initial position and which defines at least one feed passage in the end position low. The present invention also defines a fluid dispenser comprising a dispensing member, such as a pump, associated with a fluid reservoir as defined above. The dispensing member comprises a thrust member which comes into contact with the cap to move it from its initial closed position to its final open position. Advantageously, the dispensing member may comprise a body defining a fluid product inlet, the body being received in a fixing ring which comprises hooking means around the neck of the reservoir, the thrust member being formed by the ring fixation, advantageously in the form of an annular flange which extends downwardly inside the neck so as to come into contact with the cap. Thus, during assembly of the dispenser member on the reservoir, the hooking means will engage around the neck of the reservoir and simultaneously the annular flange will drive the plug in the neck to its final open position. According to one characteristic of the invention, the body can extend inside the cap. More concretely, the body of the dispensing member is disposed inside the plug cup.
    [0003] In another practical aspect, the attachment means may comprise threading engaged with threads formed outside the neck. The reservoir of the present invention may advantageously serve as a refill or cartridge adapted to be associated with a dispensing member to form a fluid dispenser. Once the tank is empty, it is simply replaced by a new full tank. This is a preferred application of the reservoir of the present invention, but which is however not unique or limiting. The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example an embodiment of the invention. In the figures: FIG. 1 is a vertical cross-sectional view through a fluid reservoir according to one embodiment of the invention; FIG. 2 is a greatly enlarged view of the upper part of the FIG. 1 dispenser; FIG. 3 is a vertical cross-sectional view through a fluid dispenser incorporating the reservoir of FIGS. 1 and 2, and FIG. 4 is a greatly enlarged view of the upper portion of the dispenser of FIG. 3. Referring to FIG. firstly to Figures 1 and 2 to describe in detail the structure of a fluid reservoir R made according to a non-limiting embodiment of the invention. The reservoir R comprises three constituent elements, namely a main body 1, a follower piston 2 and a plug 3. These three elements may be made by injection molding of suitable plastic material. However, the main body 1 can also be made of other materials such as glass, metal, composite materials, etc. It is the same with the plug 3 which could possibly be made of metal or composite material.
    [0004] The main body 1 of the tank R comprises a cylindrical barrel 11 of arbitrary, but preferably circular, section. Its lower end can be open, while its upper end forms a neck 12 defining an opening in which is engaged the plug 3. More specifically, the neck 12 extends upwards from an annular shoulder 18 which is connected The neck 12 internally defines a sliding cylinder 13 which is interrupted in its lower part by recesses 16 separated by vertical blades 17 which extend radially inwards. The inner vertical edge of the blades 17 advantageously extends in the extension of the sliding cylinder 13. Optionally, an annular ring 13a may mark the lower end of the slide cylinder 13 or the connection of the slide cylinder 13 with the vertical blades 17. This annular bead 13a projects slightly inwards so as to locally reduce the opening of the neck 12. At its upper end, the neck 12 defines an annular edge 15, possibly provided with an annular sealing ring. On its outer face, the neck 12 defines one or more threads 14.
    [0005] The follower piston 2 may be of a quite conventional type, comprising for example two piston lips 21 connected to a bottom 22. The follower piston 2 is intended to slide in a sealed manner inside the barrel 11 as fluid is extracted from the reservoir R. The displacement of the follower piston 2 inside the barrel 11 results from a depression generated inside the reservoir R. In the place of the follower piston 2, it is also possible to envisage a pocket flexible which is deformed under the effect of depression. The plug 3 is slidably engaged inside the neck 12. In its closed top initial position shown in FIGS. 1 and 2, the plug 3 is in leaktight engagement with the sliding cylinder 13. In this closed top initial position, the cap 3 closes, seals or closes the opening formed by the neck 12 of the reservoir R in an airtight and liquid-tight manner. Thus, the fluid product stored inside the R tank is safe from the outside environment. In the embodiment used to illustrate the present invention, the plug 3 comprises an annular bushing 31 from which extends downwardly a bucket 36 which defines an internal receiving space whose function will be given hereinafter. In order to reinforce the strength of the plug 3, vertical radial ribs 35 extend over the height of the sleeve and the cup 36. The annular bushing 31 defines a low annular sealing lip 32 which is continuous over its entire periphery and which it comes into sealing contact with the slide cylinder 13 in the closed up initial position, shown in FIGS. 1 and 2. The sleeve 31 also defines a high annular guide lip 33 which also comes into contact with the slide cylinder 13. that is to say that the two lips 32 and 33 are formed at opposite external edges of the sleeve 31. The sleeve 31 also defines a plurality of feed passages 34 which radially crosses the thickness of the sleeve 31. These feed passages 34 are here formed by vertical slots or notches 34a which are open at their upper ends, so as to interrupt the annuli guide lip. high area 33. As a result, the guide lip 33 does not fulfill a peripheral sealing function. In a variant that is not shown, the supply passages could simply pass radially through the bushing 31 between the low sealing lip 32 and the upper guide lip 33, without interrupting them. One can even imagine a single opening passage which is in the form of a slot or horizontal window which extends over a portion of the periphery of the sleeve 31. The embodiment of the feed passages 34 in the form of slots vertical 34a open up is only a practical embodiment, which allows to achieve the cap in an extremely simple manner by injection molding / plastic molding with a mold in two parts only. The formation of the upwardly open vertical slots 34a define upwardly extending separate tabs, each of which is reinforced by a rib 35. The outer upper edge of these tabs forms the annular guide lip 33, which is interrupted by vertical slits. However, in the closed up initial position of FIGS. 1 and 2, sealing of the reservoir is ensured by the annular sealing contact of the low sealing lip 32 with the sliding cylinder 13. Advantageously, the sealing lip 32 bears on the annular ring 13a formed at the lower end of the sliding cylinder 13, as can clearly be seen in FIG. 2. Thus, when the cap 3 is in its initial closed up position, it simply fills a Shutter function, sealing or sealing, to keep the fluid stored inside the tank away from outside air. It may also be noted that the ribs 35 may be provided with notches 35a oriented downwards, the function of which will be given below. Referring now to Figures 3 and 4 to describe in detail the positioning of the plug 3 inside the neck 12 when a dispensing member D is mounted on the reservoir R. The dispensing member D is preferably a pump but it could possibly be a valve. The dispensing member D comprises a body 4 inside which is mounted an actuating rod 5 which is axially movable back and forth. At its lower end, the body 4 forms a fluid inlet 41, which is advantageously provided with an inlet valve (not shown). Similarly, the actuating rod 5 forms, integrates or supports an outlet valve. Between these two valves, the body 4 forms a chamber 40 in which a dose of fluid can be pressurized. Indeed, by pressing the rod 5 inside the body 4, the fluid contained in the chamber 40 is pressurized, so as to close the inlet valve and open the outlet valve. Thus, the pressurized fluid product is discharged through the rod 5. In a completely conventional manner, a pusher 6 is mounted on the rod 5 in order to be able to exert the axial thrust on the actuating rod 5. In addition, the pusher 6 forms a dispensing orifice 61 at which the fluid product discharged through the actuating rod 5 is dispensed to be collected by the user. Furthermore, the dispensing member D also comprises a fixing ring 7 for fixedly mounting and sealing the body 4 in the neck 12. This fixing ring 7 may comprise a fastening skirt 71 internally provided with a thread adapted to engage the screw threads 14 of the neck 12. The fixing ring 7 may also comprise a sealing ring 72 intended to come into sealing engagement inside the sliding cylinder 13. The fixing ring 7 comprises of course receiving means 74 for fixedly and sealingly receiving the body 4. According to the invention, the fixing ring 7 also comprises an annular push flange 73 which extends downwards so as to define an edge lower thrust which comes into bearing contact with the cap 3, and more specifically with the upper face of the sleeve 31, as can be clearly seen in Figure 4. The cap 3 is then in its position f Open low in which the feed passages 34 allow communication between the reservoir R and the fluid inlet 41, as shown by the line provided with arrows in Figure 4. It can be easily understood that the screwing of the skirt 71 on the neck 12 has had the effect of pushing the plug 3 inside the neck 12 by sliding it. In the low open end position shown in FIGS. 3 and 4, it can be seen that the guide lip 33 is still engaged with the slide cylinder 13, whereas the low sealing lip 32 is now arranged at the level of the blades. vertical radii 16, so that it can no longer perform a peripheral annular sealing function. The feed openings 34 formed by the vertical slots then communicate with the recesses 16 formed between the blades 17. Although it no longer fulfills a sealing function, the low sealing lip 32 always fulfills a guiding function. remaining in contact with the inner vertical edges of the blades 17. This allows, in cooperation with the upper guide lip 33, to ensure the axial stability of the plug 3 regardless of its position. It may also be noted that the body 4 of the dispensing member D is disposed inside the cup 36 without creating a seal. After having passed through the feed passages 34, the fluid product may flow between the reinforcing ribs 35 to gain the fluid inlet 41 which is disposed at a distance from the bottom of the cup 36. The notches 35a formed on the ribs 35 come into contact with the body 4: because of their orientation, they do not prevent the descent of the body into the cup 36, but cling to the body in the opposite direction when removed from the dispensing member D of the tank. This has the effect of sliding the plug 3 in the neck so as to close the feed openings 34. The notches 35a can for example be detached from the body 4 when the sealing lip 32 bears tightly under the annular cord 13a. The tank is then sealed again. The notches 35a are here formed on the ribs, but they can be implemented anywhere on the plug or on the dispensing member in order to close the reservoir during the removal of the dispenser member. Although not shown, the plug 3 can create a peripheral seal with the body 4 above the feed passages 34. For example, it is possible to imagine that the feed passages pass through the bushing 31 without interrupting the upper guide lip 33. and that the sleeve 31 also forms a high inner lip in sealing contact with the body 4. In this variant, the fixing ring 7 may be devoid of a sealing ring 72. One can also imagine that the body 4 bears directly on the cap 3 to move it from its initial closed position to its open end position. The fixing ring 7 could then be devoid of an annular support flange 73. Whatever the modifications that may be envisaged, the stopper 3 always fulfills a shutter function in the high initial position, moves by sliding in the collar using of the dispensing member D and adopts a low end position in which one or more feed openings (s) are defined.
