    专利说明:

    [0001] The invention relates to a dispensing system for a fluid product, in particular a gel or a cream, for example a cosmetic product or a pharmaceutical product.
    [0002] The dispensing system comprises a bottle having a product conditioning tank and a dispensing member which is mounted on said bottle to be in communication with said reservoir to be supplied with product. In particular, the tank is surmounted by an access neck in which the dispenser member is slidably mounted until it comes into sealing to allow dispensing. Vials are known comprising a structural outer wall on the inner surface of which a membrane is disposed to form a flexible pouch for containing said product. To preserve the product from any deterioration in contact with the external environment, the product can be packaged in the bag in the absence of air (commonly known as "airless") and the organ is able to ensure distribution conditioned product without air intake so that, in use, air does not enter the bag in compensation for the product dispensed.
    [0003] EP-0 571 280 discloses the use of a purge ring which is interposed between the lower part of a dispensing pump and the reservoir by allowing communication between said pump and the packaged product. In particular, the ring is arranged for, on the mounting stroke of the pump, slide in the tank allowing the evacuation of air and excess product in a higher dead volume. Thus, especially taking into account the tank filling tolerances, it is possible to mount the pump on the bottle by avoiding the presence of air bubbles in said tank, to prevent degradation of the product and / or defusing of the pump.
    [0004] However, at the end of the mounting stroke of the pump, the seal may not be performed reliably enough, especially in connection with a strong requirement for the preservation of the product of any degradation in contact with the external environment.
    [0005] The invention aims to improve the prior art by proposing in particular a distribution system whose mounting of the dispensing member in the neck of a reservoir comprising a flexible bag can be achieved by ensuring an absence of air in said pocket , and this while ensuring the reliability of the seal of said assembly. For this purpose, the invention proposes a system for dispensing a fluid product, comprising a bottle having a container for packaging said product which is surmounted by an access neck to said reservoir, said bottle comprising a structural outer wall on the surface interior of which a membrane is arranged to form a flexible bag for containing said product, said system comprising a dispensing member which is intended to be mounted in the neck to be in communication with the reservoir in order to be supplied with product, said member being equipped with a lower sealing ring which is arranged for, on a mounting stroke of said member, to be able to slide in the neck allowing the evacuation of air and excess product in a higher dead volume, the neck comprising a base having a constriction whose internal dimension is arranged so that, at the end of the mounting stroke of the dispensing member n, the lower crown comes into sealed interference on the portion of the membrane which is disposed at said constriction to create a seal between the interior of said reservoir and said dead volume. Other objects and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which: FIG. 1 is a view partially showing a distribution system according to one embodiment of the invention on which a pump is shown mounted on the neck of a bottle in use, the figure showing an enlargement of the upper part of the bottle; FIGS. 2a to 2d are partial views showing the mounting of the pump on the neck of the bottle, respectively at the beginning of the mounting stroke (FIG. 2a), on the mounting stroke (FIG. 2b), at the beginning of interference of FIG. lower seal (Figure 2c) and at the end of waterproof assembly (Figure 2d). In connection with the figures, there is described below a system for dispensing a fluid product, said fluid product may be a gel or a cream, for example a cosmetic product or a pharmaceutical product. In the description, the spatial positioning terms are taken with reference to the position of the system shown in the figures. In particular, the dispensing system may be of the same type as that described in document FR-2 978 020, for example to allow the application of a product such as a liquid lipstick (lip gloss in English) or a care product for the lips. The dispensing system comprises a bottle 1 which has a tank 2 for packaging the fluid product, said tank being surmounted by a neck 3 which is arranged to allow access to said tank, in particular to pour there fluid product to be packaged and / or to dispense the fluid product that is conditioned therein. In connection with the figures, the bottle 1 comprises a cylindrical tube 1a in which the product conditioning container 2 is formed, said tube being surmounted by an upper ring 1b of reduced external dimension and in which the neck 3 is formed. The bottle 1 comprises a structural outer wall 4 inside which a membrane 5 is arranged to form a flexible bag for containing the fluid.
    [0006] In particular, the structural outer wall 4 is made of a rigid thermoplastic material such as polypropylene. Furthermore, the membrane 5 is made of a flexible plastic material, in particular based on polyethylene.
    [0007] Advantageously, the bottle 1 is made by coextrusion blowing the wall 4 and the membrane 5, not only to easily give the bottle the desired shape, but also to press the membrane 5 on the inner surface of said wall, in order to to give it dimensions similar to the dimensions of said inner surface. Thus, when the membrane 5 is filled with fluid product, it forms a flexible pouch which substantially matches the inner surface of the structural wall 4. In addition, as shown in Figure 1a, the membrane 5 is separated from the structural wall 4 In one embodiment, the membrane 5 has an outer layer based on ethylene-vinyl alcohol (EVOH) allowing such a separation with a wall 4 based on polypropylene. Thus, during an airless filling and a distribution without air intake of the product, the bag can retract into the wall 4 as and when said distribution (Figure 1). Furthermore, the structural wall 4 has an orifice 6 to allow such a retraction, said orifice being for example formed on the bottom 7 of the cylindrical tube 1 a.
    [0008] The dispensing system comprises a dispensing member 8 which is intended to be mounted in the neck 3, in particular after filling the flexible pouch with fluid, so as to be in communication with the reservoir 2 to be supplied with product.
    [0009] In the embodiment shown, the dispensing member 8 is a pump whose body is equipped with a nozzle 9 which is intended to be actuated in translation, in particular by means of a push button not shown, to enable product distribution.
    [0010] In particular, the dispensing member 8 is equipped with a lower sealing ring 10 which is arranged so as to be able to slide in the neck 3 over a mounting stroke of said member, allowing air and product to be evacuated. in excess in a higher dead volume 11. Thus, the mounting of the dispensing member 8 on the bottle 1 can be performed by avoiding the presence of air bubbles in the tank 2, to prevent degradation of the product and or defusing said organ. Moreover, the assembly makes it possible to take into account the filling tolerances of the tank 2 by evacuating with air the product possibly excessively poured into the tank 2. In the embodiment shown, the distribution system comprises a sleeve 12 which is associated around the lower portion 13 of the dispensing member 8 and which carries the lower sealing ring 10. In particular, the sleeve 12 has a central well 14 in which the lower portion 13 of the body of the dispenser member 8 is mounted in tight and tight contact, the lower sealing ring 10 being formed around a lower end of said central well. The central well 14 comprises a bottom which is provided with a lower orifice 15 opposite which an orifice of the lower part 13 of the dispensing member 8 is arranged, in order to allow the feeding of the dispensing member 8 to through said holes when said member is mounted on the bottle 1. The sleeve 12 further has an upper ring 16 formed around the upper end of the central well 14, said upper ring being arranged to seal the interference assembly in the neck 3, the dead volume 11 being formed between said upper ring and the lower ring 10.
    [0011] In addition, the sleeve 12 has an upper flange 17 which extends radially from the upper end of the upper ring 16, said flange being intended to come into axial abutment against the upper wall of the neck 3 at the end of the assembly stroke. the member 8 in said neck.
    [0012] Advantageously, the dispensing member 8 is of the type without air intake in compensation for the volume of dispensed product, so as not to introduce air into the reservoir 2 during use of the system, and thus to preserve the product from any deterioration in contact with the external environment.
    [0013] In connection with the figures, the sleeve 12 is arranged to have in the neck 3 only the lower part 13 of the dispensing member 8, the upper part 19 of said member, on which the vent orifice 18 is formed, remaining outside said neck being further isolated from the tank 2 thanks to the sealing rings 10, 16. For a good sealing of the assembly, the neck 3 comprises a base which has a constriction 20 whose inner dimension is arranged so that, at the end of the mounting stroke, the lower ring 10 comes into sealed interference on the membrane portion 5 which is disposed at the level of said constriction to create a seal between the inside of the tank 2 and the dead volume 11. In connection with the Figures, the constriction 20 has a V-shaped geometry formed by an upper bearing surface 20a inclined radially inwardly and a lower bearing surface 20b inclined radially outwardly. In particular, the constriction 20 has, at the tip of the V, a minimum inside diameter at which the lower ring 10 is intended to come into sealed interference with the membrane 5 to seal at the end of mounting stroke.
    [0014] Advantageously, the upper bearing surface 20a extends under the ring 1b, and thus under the neck 3, while the lower bearing surface 20b extends above the tube 1a, and thus above the reservoir 2. , by deporting the constriction 20 under the neck 3, it avoids the diameter fluctuations at said neck to better control the sealing interference between the lower ring 10 and said tightening, which ensures a good seal at the end mounting of the dispensing member 8.
    [0015] In particular, the formation of such a constriction 20 is easy when the bottle 1 is made by coextrusion blow molding, in particular by providing in the mold a boss of complementary shape to that of the desired tightening 20. Furthermore, the embodiment of the membrane 5 with an inner layer of relatively flexible material, such as polyethylene, allows the membrane portion 5 covering the constriction 20 to be deformed by the lower crown 10 and therefore to improve the seal. The lower ring 10 further has an outer diameter which is between the nominal inside diameter of the neck 3 and the minimum inside diameter of the constriction 20, which allows said lower crown to be able to slide easily in said neck during assembly and to come frankly interference at said tightening at the end of said assembly.
    [0016] In the embodiment shown, the lower ring 10 is deformable radially between a free mounting state and a compressed state of tight interference on the constriction 20. In particular, the lower ring 10 is deformable and has an axial annular flap 10a connected central well 14 by a radial annular platform 10b, said annular platform forming a hinge to allow pivoting of said flap between its two states. In relation with FIGS. 2, the mounting of the dispensing member 8 on the bottle 1 is described, in particular after filling the reservoir with the fluid product to be dispensed.
    [0017] In Figures 2a and 2b, we see that the lower ring 10 is in free state, and can slide easily without interference in the neck 3 with its outer diameter which is smaller than the nominal diameter of said neck. Furthermore, the space between the lower ring 10 and the neck 3 allows the air present in the tank 2, and even a small amount of product contained in excess in said tank (Figure 2b), to go back to the volume death 11.
    [0018] As shown in FIG. 2c, once the free edge of the flap 10a comes into contact against the constriction 20, the lower crown 10 deforms radially, in particular by folding said flap on the central well 14, in order to allow said free edge to to cross said constriction. The vent grooves 16a arranged below the upper ring 16 allow the evacuation of air to the outside and avoid the pressurization of the reservoir 2. Finally, as shown in Figure 2d, once the rim upper 17 of the sleeve 12 abuts against the neck 3, the lower ring 10 is deformed again, in particular by radial deployment of the flap 10a under the constriction 20, to reach its compressed state of interference tight on said tightening. Moreover, the upper ring 16 comes into sealed interference against the membrane portion 5 disposed near the upper opening of the neck 3.
    [0019] During assembly, the air present in the tank 2 is discharged into the dead volume 11, where it remains trapped at the end of said assembly. On the other hand, once the air is completely discharged, a small amount of product may overflow over the lower crown 10 and remain contained in the dead volume 11 while the watertight interference of the upper crown 16 in the neck 3 ensures the maintenance and sealing of the dispensing member 8 in said neck (Figure 2d). The air contained in the dead volume 11 is no longer in contact with the packaged product in the tank 2, so that the bottle 1 is purged of the air that had entered during its filling and can distribute without leaving the air come in contact with the product.
