Definitions
- Tank provided with a closing and filling device and / or fluid product dispensing device comprising such a tank.
- the present invention relates to a device for closing and / or filling a reservoir as well as a device for dispensing a fluid product comprising such a reservoir.
- the present invention is particularly suitable for use in a liquid spraying device, in particular in the field of pharmacy.
- a first problem concerns the stability and contamination of the product. Indeed, during its storage period, a liquid product tends to evaporate and / or could be contaminated by external agents such as bacteria, or even oxidized by oxygen. To avoid evaporation, a tight seal and the use of non-permeable materials for the constituent parts of the tank are necessary. To avoid contamination, it is important to minimize the number of different materials in contact with the fluid, and these materials should also be inert to the product. Suitable materials for fulfilling these two requirements include for example glass for the tank, and special rubbers which do not interact with the liquid product for the sealing device (s).
- the product for example the vaccine
- the product will only be available a few months before its use (2 to 3 months), and the filling of millions of devices will have to be carried out in a very short time.
- Yet another problem that arises concerns precompression.
- the quality of the spray and the size of the particles depend on the pressure supplied to the liquid at the time of its expulsion.
- a rubber stopper which also serves as a pump piston, is pierced at the time of actuation by a hollow needle which is connected to the spray nozzle of the device.
- This solution solves the problem of the stability and contamination of the product contained in the tank, since it uses only glass and rubber, but it does not overcome the problem of filling after assembly of the tank . Indeed, the tank must be filled separately before the final assembly of the device. On the other hand, no precompression is provided by this system since the resistance of the rubber to the penetration of the needle is very limited.
- the piercing provided by the needle can in some cases remove small particles of rubber which could clog the spray or be ejected into the user's nasal cavity.
- the closure is carried out in a relatively simple manner, the opening of the device is complex, requires several components, and is difficult to handle, in particular because of the presence of a needle.
- the object of the present invention is to provide a closure and / or filling system for a reservoir, in particular intended for use in a spraying device, which does not have the abovementioned drawbacks.
- the object of the present invention is to provide a reservoir comprising a simple and effective closure which is opened by the pressure which is created inside the reservoir at the time of actuation, without the need for a complex opening system. which removes or pierces or removes parts of components.
- the present invention also aims to provide such a tank which is simple and inexpensive to manufacture and assemble.
- the present invention also aims to provide a closure and / or filling system which allows the use of a minimum of materials in contact with the product contained in the tank, and in particular glass for the tank and a rubber having inert characteristics vis-à-vis the product for the closure element.
- Another object of the present invention is to provide a closure and filling system for a reservoir, which can be used as a liquid inlet for a easy and quick filling, filling can in particular be carried out before the complete final assembly of the fluid dispenser device incorporating said reservoir.
- the present invention also aims to provide a closing and / or filling system which opens, to allow the expulsion of the liquid, only if a sufficiently high and predetermined pressure is created during actuation of a reservoir, so that the product is expelled with some precompression. This is particularly advantageous in the context of a spraying system.
- the present invention also aims at a tank comprising a closing and filling device which simultaneously fulfills all the above requirements, that is to say that it ensures the stability of the product contained in the tank, which it avoids contamination of this product by chemical interaction, that it allows rapid and simple filling of the reservoir, in particular after final assembly of the device, and that it ensures the expulsion of the product with a predetermined precompression.

- - Figure 6 is a schematic sectional view of a reservoir comprising a closure device and filling carried out according to another alternative embodiment of the present invention, in the closed position.
- the present invention is applicable to all fluid dispenser devices.
- FIG. 1 there is shown a first alternative embodiment of the closure and filling device for a reservoir according to the present invention.
- the reservoir 10, the walls 11 of which are preferably made of glass, in this variant has only one opening, closed by a closure and filling device according to the invention.
- This closure and filling device comprises a closure element 20 which acts as a sealing closure cap in the rest position, shown in FIG. 1.
- This closure element 20 comprises an annular part 21 whose diameter outer substantially corresponding to the inner diameter of the tank 10, and a central portion 22 for sealing the tank in the rest position.
- the central part 22 has a bottom wall 23 which is provided with one or more slots 24 adapted to open under the effect of a predetermined minimum pressure.
- the closure element 20 has an axial bore 22 which is closed on one side by said bottom wall 23, and said bottom wall is preferably made of an elastically deformable material.
- the shutter element 20, as a whole, is made of the same material, which facilitates its manufacture. In the variant embodiment shown in FIGS. 1, 2 and 3, the closure element 20 acts as a sealed closure cap in the rest position.
- the seal is produced in the rest position by the bottom wall 23 of the closure element 20, the slot 24 of which is kept sealed by the pressure exerted by the walls 11 of the reservoir 10 on the annular part 21 and the bottom wall 23 of the closure element 20.
- the closure element advantageously further comprises a radial flange 29 which extends outside on the upper edge of the reservoir 10, to form a stop against any displacement accidental closure element 20 inside the tank 10.
- the central bore 22 of the closure element 20 is adapted to receive the end 32 of an actuating member 30 of the fluid dispenser device (not shown) via of which the actuating force exerted by the user on said actuating member 30 is transmitted to the shutter element 20.
- Said end 32 of the actuating member 30 cooperates with the central bore 22, advantageously with a bearing zone 28 of said closure element 20, by means of a shoulder 38 of the actuating member 30, to transmit said actuating force.
- the end 32 of the actuating member 30 has a concave shape so that the bottom wall 23 can deform inside said concave end 32 to allow the 'opening of the slot 24.
- the pressure therefore increases inside the tank 10 until the predetermined minimum threshold is reached which causes the deformation of the bottom wall 23 towards the concave part of the end 32 of the member d actuation 30, and therefore the opening of the slot 24.
- the radial flange 29 of the closure element 20 folds down along the actuation rod 30 under the effect of the force released by the opening of the slot 24 so that the element shutter 20 turns into a piston sliding inside the walls 11 of the reservoir 10, which then forms the pump body.
- the precompression carried out by the closure element 20 guarantees that the product contained in the reservoir is expelled from the reservoir with optimum pressure.
- the closure element 20 then acts as a piston and is moved towards the bottom of the reservoir 10, to expel the product that it contains, through the slot 24 and an expulsion channel provided in the rod. actuation 30.
- the precompression threshold necessary to deform the bottom wall 23 and open the slot 24 can be determined by choosing an appropriate thickness and / or geometry of said bottom portion 23.
- the geometry of the bottom wall 23 is such that it forms a curved surface, in particular concave , on the side directed towards the actuating rod 30. This concave shape forms a resistance to deformation which makes it possible to precisely define the pressure threshold necessary for the opening of the slot 24.
- said bottom wall 23 may include a longitudinal slot 24, as shown in Figure 3b, or two or more slots made for example in cross shape, or any other appropriate motif.
- FIGS. 3a and 3b the shutter element 20 of the device in FIGS. 1 and 2 is shown in the filling position.
- the filling is carried out through the same closure element 20 which serves as a closure plug in the rest position, and as a piston during dispensing.
- the filling must generally be carried out before the final assembly of the fluid dispenser device, in which said reservoir will be adapted.
- the reservoir is automatically closed at the end of filling by closing the slot 24 after removal of the filling tube.
- a filling arrangement 40 fits inside the central bore 22 of the closure element 20, said filling arrangement 40 comprising a radial flange part 45 cooperating with the flange 29 of the closure element 20 and the wall 11 of the reservoir 10, as shown in FIG. 3b.
- the filling arrangement also comprises a filling tube 41 which comes to bear on the bottom wall 23 from the outside to deform it, open said slot 24 and enter the interior of the reservoir 10. As shown diagrammatically in FIG. 3b, it can be seen that the penetration of the filling tube 41 through the slot 24 provides lateral openings 27 around said filling tube 41, which allow the air contained in the tank to escape during the filling of said tank.
- the radial flange 45 which cooperates with both the closure element 20 and the wall 11 of the tank, avoids during the application of force on the bottom wall 23 to deform the latter in order to allow penetration of the filling tube 41, that said closure element 20 is moved inside the tank.
- This first variant of the present invention which has only one shutter element 20 acting at the same time as a closure cap, piston, and filling element makes it possible to solve all the above-mentioned problems, except that it generally not allow filling of the reservoir after final assembly of the fluid dispenser device.
- the present invention advantageously provides a second closure element 120 disposed on the other side of the reservoir 10 and which acts as a closure cap and as a filling element to allow filling of the reservoir , even after assembly in the dispensing or spraying device.
- the closure element 120 is produced in a similar manner to the closure element 20, preferably it is produced in an identical manner, that is to say that it comprises an annular part 121 and a central part 122. , preferably comprising a central bore 122, closed on one side by a deformable bottom wall 123 which incorporates a slot 124 which can open under the effect of a predetermined force.
- a hollow rigid member 130 is disposed in said bore 122 of the filling element 120.
- the radial end wall 132 of said hollow rigid member 130 is preferably made in a flat manner, that is to say it is disposed facing said wall deformable bottom 123 by preventing the latter from deforming towards the outside of the tank 10 under the effect of a pressure created inside said tank.
- a perfect seal is ensured during the distribution of the product through the other end of the tank.
- Said closure element 120 therefore acts as a tight closure cap in the rest position and during dispensing of the product.
- the hollow rigid member 130 comprises a radial flange 135 which cooperates with the radial flange 129 of the filling element 120 and with the wall 11 of the reservoir 10 so as to prevent displacement of said element 120 at the inside the tank 10 when pressure is exerted from the outside on the bottom wall 123, in particular during filling.
- the filling of the reservoir 10 in this second variant embodiment shown in FIGS. 5a and 5b is carried out in a similar manner to the filling of the reservoir of the first variant shown in FIG. 3a, with the difference that this filling can be carried out while the tank is already assembled in the fluid dispenser.
- the filling assembly 140 in particular the filling tube 141 is brought through said hollow rigid member 130 to rest on the bottom wall 123, deform it and pass through the slot 124.
- the filling element 120 not being intended to serve as a piston during the dispensing of the product, it can be easily accessible by the filling device itself when the tank is already assembled in the device.
- the reservoir 10 is returned relative to the position shown in Figure 4 to allow air to escape through the openings 127 provided around the filling tube 141 in the slot 124, and avoid any leakage of liquid through said openings 127.
- the filling element 120 has been shown in FIGS. 4 and 5 in conjunction with a filling element 20 described previously in the context of the first alternative embodiment. It should however be understood that the invention also covers a reservoir 10 comprising only one filling and filling element 120 which acts as a tight closure cap, and as a filling element for filling the reservoir , even when it is already assembled on the final device.
- the closure on the other side of the reservoir and the dispensing of the product contained in the reservoir are in this case not necessarily carried out by a closure element 20 as described above.
- FIG. 6 there is shown a third embodiment, adapted more particularly to a single-dose device for lyophilized drug.
- the reservoir 10 is separated into two sub-reservoirs 110 and 210 by a third closure element 220 which is fixedly disposed, via a portion of radial flange 229, inside said reservoir 10.
- This third element d the shutter 220 is produced in a similar manner to the first and second shutter elements 20 and 120, and in particular comprises an annular part 221 inserted in leaktight manner inside the O 00/24523
- the sub-reservoir 110 comprises a lyophilized powder
- the sub-reservoir 210 comprises a liquid solvent for the lyophilized drug.
- the second closure element 120 arranged in FIG. 6 on the lower side of the reservoir 10, acts in this alternative embodiment as a closure cap in the rest position, possibly as a filling element for filling the sub -reservoir 210, but also as a piston for mixing the freeze-dried product and its solvent. The actuation of this device is carried out in two phases.
- the liquid contained in the sub-tank 210 is transferred into the sub-tank 110 through the slot 224 provided in the bottom wall 223 of the third closure element 220 by exerting a pressure in the sub-tank 210 by means of an actuating element (not shown) acting on the hollow rigid member 130 of the second closure element 120.
- Said pressure created in the sub-reservoir 210 causes the deformation of the bottom wall 223 and opening the slot 224 so that the liquid solvent is transferred inside the sub-tank 110 via the piston 120.
- said mixture is expelled through the expulsion channel 31 from the actuating member 30 by means of the first closure element 20 as described above with reference to FIGS. 1, 2 and 3.
- the third shutter member 220 includes a hollow rigid member 230 inserted in its central bore 222 and the end 232 is formed so flat.
- the bottom wall 223 can deform in the direction of the sub-tank 110 to allow the passage of the solvent during the first phase, but cannot deform in the other direction, during an overpressure created in the sub-tank 110 during the expulsion of the mixture, thus guaranteeing the seal.
- the rigid member 130 inserted in the central bore 122 of the second closure element 120 advantageously also has an end 132 produced in this way to avoid any leakage of solvent during the first phase, during which an overpressure is created inside. of the sub-tank 210.
- the slot 124 can only open inwards to allow a filling tube to pass, if necessary.
- the present invention therefore makes it possible to produce, in a very simple and inexpensive manner, a closure and filling device for a reservoir which makes it possible to overcome all the drawbacks mentioned above.
- the reservoir may have a single closure element, but in the preferred embodiment, it has two closure elements, one at each end of the reservoir, the first serving as a sealed cap in the rest position and as a piston during dispensing. of the product, and the second acting as a tight closure cap and as a filling element, making it possible in particular to fill the reservoir after its assembly in any suitable device or sprayer.
- the present invention has been described with reference to three alternative embodiments, but it is understood that these are not limitative, those skilled in the art can make various modifications without departing from the scope of the present invention as defined in the appended claims.
- the invention is not limited to single-dose devices.
- stop means or the like can be provided to effect the expulsion of the product contained in the reservoir in two or more actuations of the device.
