Definitions

  • the present invention relates to an aerosol dispensing device comprising a ring.
  • rings with aerosol dispensing valves including metering valves mounted on a reservoir containing the product to be dispensed. These rings are used in particular in valves used in the inverted position, that is to say with the valve disposed below the tank at the time of expulsion of a dose of product.
  • These rings generally serve mainly two functions, namely on the one hand to ensure the distribution of a maximum amount of the product contained inside the tank, limiting the dead volume located under the valve inlet when the latter it is in reverse position of use.
  • the rings also serve to limit the contact of the product with the neck seal disposed generally between the neck of the reservoir and the ring or fixing cap, which serves to fix the valve on the container.
  • the ring is assembled on the valve body by radially clamping an inner edge of the ring on said valve body.
  • This implementation has the disadvantage that when this radial clamping is too strong, it can over time induce a deformation of the valve body, and especially inside said body, which can cause a malfunction of the valve. Indeed, many valves provide a relatively narrow space between the valve that slides and the valve body. Radial deformations of the valve body can then cause friction and even blockage of said valve.
  • the ring is generally in contact by its outer portion with a portion of the neck of the tank.
  • this crimping causes a radial deformation of the neck of the tank, thereby increasing the radial compression exerted on the ring. Again, this increase in the radial compression transmitted to the inner edge of the ring can cause an increase in the stresses exerted on the valve body and a deformation thereof.
  • the present invention aims to provide an aerosol dispensing device comprising a ring which does not reproduce the aforementioned drawbacks.
  • the present invention aims to provide an aerosol dispensing device having a ring which avoids excessive radial stress on the valve body, thus avoiding any risk of excessive deformation of the valve body, particularly when crimping the valve. valve on the tank.
  • Another object of the present invention is to provide such a ring which makes it possible to compensate for the manufacturing and assembly tolerances without increasing the radial stresses on the valve body.
  • the present invention also aims to provide such a ring which ensures maximum emptying of the contents of the tank.
  • the present invention also aims to provide such a ring which limits as much as possible the contact between the neck seal and the product contained in the reservoir.
  • the present invention also aims to provide such a ring that is simple and inexpensive to manufacture and assemble.
  • the present invention therefore relates to an aerosol dispensing device according to claim 1.
  • Advantageous embodiments are described in the dependent claims.
  • said outer portion cooperates sealingly with a portion of the reservoir after assembly of said fastener element on the reservoir, to prevent contact between the product to be dispensed and a neck seal disposed between the reservoir and the fastener.
  • the ring has only one inner portion in contact with the valve body.
  • said ring is out of contact with the neck seal.
  • said ring is in contact with said neck seal, and wherein after fixing the fastener element on the reservoir, the deformed axial wall portion biases the ring against said neck seal to improve the seal.
  • said neck seal is disposed away from the valve body, the contact surface between said neck seal and said ring being weak.
  • said ring is made in one piece with said valve body at an inner portion of the ring forming a connecting portion.
  • the outer surface of the deformable axial wall portion is substantially smooth, preferably polished-ice, before fixing the fastener.
  • said valve body comprises at least one opening to allow the product to pass from the reservoir into said valve, said bottom surface of said peripheral space and said radial grooves being located at the lower edge of said opening, in the position of use. inverted, with the valve disposed under said reservoir.
  • the aerosol device comprises a reservoir 1 containing the product to be dispensed.
  • This product may be of the pharmaceutical type, and propellant may be provided for distribute this product through an aerosol valve 20, preferably a metering valve.
  • This aerosol valve comprises a valve body 21 in which slides a valve 30.
  • the valve body 21 is assembled on the neck of the tank 1 by means of a ring or attachment cap 50, in particular of the crimping type, preferably with interposition a neck seal 40 to seal.
  • the valve shown is particularly intended to be used in the inverted position, that is to say that when a dose is expelled, the valve is located below the tank. This valve may also be suitable for valves used in the upright position.
  • valve body may be equipped with a tube for delivering the liquid into the chamber via the valve body.
  • the valve body 21 has one or more openings 22 for filling the valve with product from the reservoir. These openings are shown in the form of lateral longitudinal slots 22 extending over a portion of the height of the valve body 21. Alternatively, one or more openings (s) of different shapes could be provided for this purpose.
  • a ring 10 is assembled around the valve body 21.
  • This ring 10 is intended primarily to perform two functions, namely on the one hand to ensure the most complete emptying of the tank, by limiting the volume as much as possible. dead below the lower edge of the opening (s) 22 of the valve body 21, when the valve is in the reverse use position.
  • the ring also serves to limit as much as possible the contact between the product contained in the tank 1 and the neck seal 40.
  • the ring can prevent any contact between the product and the neck seal 40, by forming a seal with a portion of the reservoir after crimping the capsule 50.
  • the ring 10 comprises at least one inner portion 11 which is intended to cooperate with the valve body 21.
  • the inner portion 11 is the radially innermost portion of the ring 10.
  • a second inner portion 11 ' is provided to cooperate with another portion of the valve body.
  • the ring 10 has an outer portion 15, preferably radially outermost, which comprises a deformable axial wall portion 16 adapted to deform elastically radially inwardly.
  • This deformable wall 16 has in particular the purpose of compensating and absorbing any radial stresses that may be exerted on it by the reservoir 1, in particular when at the time of crimping the attachment cap 50, the latter is deformed radially. towards the inside.
  • the deformable wall 16 extends from an upper part of the ring (in the position shown on the Figures 1 to 4 ) which is in contact with or near the neck seal 40, axially towards the bottom of the tank. This implementation facilitates the assembly of the ring around the valve body 21.
  • the ring with dimensions such that the deformable portion is deformed only during the crimping of the capsule 50, but neither when assembling the ring around the valve body, or during insertion of the valve into the reservoir, which could cause axial movement of the ring along the valve body.
  • this specific form with the deformable wall 16 pointing towards the bottom of the tank allows it to participate in guiding the product towards the opening (s) 22 of the valve body, as notably visible on the figure 4 .
  • the contact between the reservoir and the wall deformable 16 is made in a zone of the deformable wall capable of easily deforming. In the example shown on the figure 1 this zone is located approximately in the middle of said deformable wall 16. It could be axially offset, but should preferably not be located at the very beginning of this wall, where the capacity of elastic deformation would be low or zero.
  • a deformable wall directed towards the bottom of the tank is that in one embodiment where the neck seal 40 is in contact with the ring 10, the ring 10 is biased axially or pushed against said seal 40 after crimping. Indeed, the wall 16 after deformation exerts a force whose component is axial and directed towards the joint. This improves the fixing of the ring 10 on the valve body 21.
  • this constraint of the neck seal 40 has the effect of improving the seal for a better distribution of stresses on the seal, in particular during the crimping of the seal. the capsule. With a deformable wall that would be directed in the other direction, the ring would instead be solicited away from said seal after deformation of the wall. Fixing the ring 10 on the valve body 21 should therefore be stronger to compensate for this stress, increasing the risk of a negative effect on the valve body. In addition, the seal at the neck seal 40 would not be improved.
  • the outer surface of the outer portion 15, in particular of the deformable axial wall portion 16 is smooth, preferably polished-ice, that is to say with a roughness index of less than 1.0, advantageously less than 0.8, preferably about 0.05.
  • This implementation promotes a sealing contact between the reservoir and the ring after crimping.
  • the ring 10 comprises a deformable wall portion 16 prevents a deformation of the reservoir 1 is automatically transmitted to the (x) inner edge (s) 11 and 11 'thereof, and therefore to body of valve 21. This avoids any risk of deformation of the valve body 21, which may cause a blockage or malfunction of the valve. Furthermore, after deformation, the contact between the deformable wall and the reservoir may create a peripheral seal that will prevent any contact between the product and the neck seal 40. This eliminates any risk of contamination of the product to be dispensed.
  • the figure 11 represents the simplest version.
  • the deformable axial wall portion 16 forms the radially outer portion 15 of the ring 10 and extends radially inwardly by a peripheral space 17 extending towards the radially inner edge 11.
  • the peripheral space 17 simply comprises a bottom surface.
  • the bottom surface of the peripheral space 17 can be horizontal in the position shown on the figure 4 or slightly inclined.
  • this bottom wall is terminated in said radially inner portion 11 substantially at the upper edge of the opening 22 of the valve body 21, as shown in FIG. figure 4 .
  • This upper edge of the opening 22, in the right position shown on the figure 4 obviously corresponds to the lower edge of the same opening 22 in the inverted position of the valve. This ensures maximum emptying of the product contained within the tank by limiting, or eliminating, any dead volume for said product when the valve is in the reverse use position. A slight inclination of the bottom surface peripheral space 17 would further promote this function.
  • the ring 10 further comprises a central axial wall 19 which separates said radially inner portion 11 from said peripheral space 17 and said deformable axial wall portion 16 forming the outer portion 15 of the ring 10.
  • This central axial wall 19 is then provided at least one radial through groove 12 which is intended to connect said peripheral space 17 to said radially inner portion 11.
  • the function of this at least one radial through groove 12 is only to prevent the product from stagnating inside.
  • said peripheral space 17 provided to allow radial deformation of the deformable wall 16. This limits the maximum dead volume for the product when the valve is in the reverse use position.
  • said central axial wall 19 has a radially outer rear face 13 which is substantially axial, that is to say substantially vertical in the straight position shown in particular on the figure 2 and a radially inner front face 14, which is advantageously inclined, preferably connecting the top of said central axial wall 19 to said radially inner portion 11.
  • This implementation clearly visible on the Figures 5 to 10 , makes it possible to guiding the product in the direction of said internal radial edge 11 of the ring 10, and consequently in the direction of the opening 22 provided in the valve body 21.
  • This is notably clearly visible on the figure 3 , in which it is found that the radially inner edge 11 of the ring is disposed substantially at the upper edge (in the upright position) of said lateral opening 22 of the valve body 21.
  • the figure 6 shows a ring 10 with a single radial through groove 12, while the Figures 7 and 8 show a ring with two through radial grooves 12, preferably diametrically opposed.
  • the figure 9 shows such a ring with four through radial grooves 12, and the figure 10 shows a ring with six radial grooves 12.
  • the number of grooves 12 can be any.
  • the peripheral space 17 and the radial groove (s) 12 comprise a common bottom surface which can, as for the variant of the figure 11 or be substantially flat, or slightly inclined to promote the guiding of the product towards the opening 22 of the valve body, in the reverse use position.
  • radial groove (s) through (s) 12 may comprise side walls 18 substantially axial, that is to say substantially vertical in the right position.
  • these side walls 18 may be more or less inclined.
  • figure 8 shows strongly inclined walls, this implementation particularly promoting the flow of the product towards the opening (s) 22 of the valve body 21, when the valve is in the reverse use position.
  • the ring 10 is not in contact with the neck seal 40, which is fixed directly between the valve body 21 and the tank 1.
  • the ring 10 may be in peripheral sealing contact with the tank 1, at its level. external part 15, after crimping the capsule 50.
  • the ring of this variant has only one point of contact 11 with the valve body 21, which can be provided at a radial shoulder of the latter. this.
