Definitions
- the present invention relates to a ring for aerosol dispensing valve.
- 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 a radial clamping of an inner edge of the ring on said valve body, in particular by being force-fitted.
- This implementation has the disadvantage that when this radial clamping is too strong, it can over time induce a deformation of the valve body, including 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. Especially when the attachment capsule is a capsule crimping, this crimping can cause a radial deformation of the neck of the tank, thereby increasing the radial compression exerted on the ring.
- the present invention aims to provide a ring and an aerosol dispensing device comprising such a ring that do not reproduce the aforementioned drawbacks. More particularly, it is an object of the present invention to provide an aerosol dispensing device ring which limits excessive radial stresses on the valve body, thereby limiting the risk of excessive deformation of the valve body, particularly during crimping of the valve body. the valve on the tank. The present invention also aims to provide such a ring that compensates for manufacturing 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 eliminates contact between the neck seal and the product contained in the tank.
- 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 a ring intended to be arranged around a valve body of an aerosol dispensing valve mounted, by means of a fastening element, such as a fixing cap. crimped on a reservoir containing the product to be dispensed, said ring comprising at least one inner part cooperating with said valve body, and an outer part, said ring being made in a substantially rigid one-piece piece, said outer part being adapted to cooperate with sealed manner by deformation of material with a portion of the tank during assembly of the fastener on the tank.
- said ring is dimensioned so that it cooperates sealingly with the reservoir after assembly of the fastener element on the reservoir.
- said outer portion forms a smooth surface, preferably polished ice, before assembly of the fastening element on the reservoir.
- said at least one inner portion has a small contact surface with the valve body.
- said ring has a radially inner portion cooperating with a portion of the valve body and a second inner portion cooperating with another portion of the valve body.
- the ring has only one inner portion in contact with the valve body.
- the upper surface of the ring comes into contact with a neck seal, and extends over most of the lower surface of said neck seal.
- said ring is out of contact with the neck seal.
- said ring is integrally connected with said valve body, at an inner portion of the ring forming a connecting portion.
- the present invention also relates to a fluid dispensing valve, comprising a ring as described above.
- the present invention also relates to a fluid dispenser device comprising a valve as described above mounted on a reservoir.
- Figure 1 is a schematic cross-sectional view of an aerosol dispensing device having a ring according to a first embodiment of the present invention, in the upright position;
- Figure 2 is an enlarged detail view of a portion of the device of Figure 1;
- Figure 3 is a schematic sectional view showing another embodiment of the invention;
- Fig. 4 is a view similar to that of Fig. 3 showing still another embodiment of the present invention.
- 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 dispensing this product through an aerosol valve 20, preferably a metering valve.
- This aerosol valve comprises a valve body 21 in which a valve 30 slides.
- the valve body 21 is assembled on the neck of the tank 1 by means of a fixing ring or cap 50, in particular of the crimpable type, with the interposition of 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.
- the valve body 21 has one or more openings 22 for filling the valve with product from the reservoir. These openings are represented in the form of lateral longitudinal slots 22 extending over a portion of the height of the body valve 21. Alternatively, one or more openings of different shapes could be provided for this purpose.
- a ring 10 is arranged around the valve body 21.
- This ring 10 serves in particular to ensure the most complete emptying of the tank, limiting as much as possible the dead volume located below the lower edge of the or opening (s) 22 of the valve body 21, when the valve is in the reverse use position.
- the ring 10 comprises at least one inner portion 1 1 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 intended to cooperate with another part of the valve body.
- the ring 10 also comprises an outer portion 15, preferably radially outermost, which comprises a rigid axial wall portion adapted to deform plastically during crimping of the cap 50.
- This deformable wall 15 has in particular the purpose of partially compensating and absorb the radial stresses that are exerted on it by the tank 1, when at the time of crimping the fixing cap 50, the tank deforms radially inwards.
- the fact that the ring 10 comprises such a deformable wall portion prevents such deformation of the tank 1 is entirely transmitted to the inner edge 11 thereof, and therefore to the valve body 21. This limits the risk deformation of the valve body 21, which could cause a blockage or malfunction of the valve.
- the ring 10 eliminates any contact between the neck seal 40 and the product contained in the tank 1. More particularly, during the crimping, the portion of the reservoir which deforms against the outer wall 15 of the ring will actively interfere with this wall by elastically deforming and exerting a radial pressure on it, thereby creating a peripheral seal, preventing any contact between the product and the For example, the portion of the reservoir that deforms will cause creep of the outer wall 15 of the ring, this permanent deformation of the material creating a complete seal.
- the dimensions of the ring 10 are chosen so that the seal is achieved only after crimping, but not during the establishment of the ring 10 around the valve body 21.
- the ring 10 is made of a substantially rigid one-piece piece, advantageously made of nylon.
- the outer surface of the deformable wall 15 of the ring is flat and smooth, preferably polished-ice, and is in particular devoid of any coating or surface modification that would make the realization of the ring more complex and therefore more expensive. This smooth surface also promotes assembly, including the insertion of the valve into the reservoir.
- the ring 10 advantageously comprises an upper surface 17 in contact with a major part of the lower surface of the neck seal 40. Furthermore, the ring 10 advantageously comprises two contact points 11, 1 1 'with the valve body, the surfaces of these contact points being small to simplify and facilitate the assembly of the ring 10.
- a conical surface 18 is provided to guide the product towards the opening (s) ) 22 of the valve body.
- Figures 3 and 4 show other embodiments of the invention.
- 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 is according to the invention in peripheral sealing contact with the tank 1, at its outer portion 15, after crimping the cap 50.
- the ring of this variant has only one contact point 1 1 with the valve body 21, which can be provided at the a radial shoulder thereof.
- the advantage of this variant is that the ring has a very simple shape, which is easy and economical to achieve.
- the ring 10 is made in one piece with the valve body 21, the inner portion 11 of the ring forming the connecting portion.
- This implementation simplifies the assembly of the valve, since it removes the assembly step of the ring on the valve body.
- the structure of the valve can be any.
- the shape of the valve body and the openings may be different from that shown. It is the same with the tank, and especially its neck. In general, any modification is possible without departing from the scope of the present invention as defined by the appended claims.
