More particularly, the present invention relates to a crimping capsule for fixing a metering valve to the neck of a container with the interposition of a neck seal to ensure sealing at the neck of the container.
- a typical fixing element generally comprises a receiving part for fixedly receiving the dispensing member, a fixing part for fixing to the neck of said container, and an "intermediate" part which, after positioning of the fixing element ensures the positioning of the neck seal on the upper edge of the container neck to guarantee sealing.
- These typical fasteners which can be screwable or snap-on rings, or crimpable capsules, have a number of drawbacks:
- EP-0 101 157 and WO 94/16970 disclose a fixing capsule for an aerosol container comprising an annular housing intended to receive the neck seal.
- the dimensions of said housing are substantially identical to the dimensions of the neck seal, the latter being inserted in said housing by force, so that it is already prestressed before it is assembled on the neck of the container.
- the seal must have very precise dimensions to fit in said housing, so that no tolerance for manufacturing the seal is acceptable, which necessarily implies the use of very expensive seal manufacturing processes, such as molding or overmolding.
- the housing of the fixing capsule must also be produced with high dimensional precision, which complicates its manufacture and therefore its cost.
- the present invention aims to provide a fastening element which does not reproduce the aforementioned drawbacks.
- the object of the present invention is in particular to provide a fixing element which is simple and inexpensive to produce.
- the present invention also aims to provide such a fastening element which allows the use of a neck seal with reduced surface area while eliminating the positioning ring of the seal.
- the present invention also aims to provide such a fastening element which makes it possible to manufacture neck seals with simple means, inexpensively, and which allows relatively high manufacturing tolerances.
- Another object of the present invention is to provide a fastening element which makes it possible to produce neck seals according to any desired manufacturing methods and with any desired suitable materials.
- the present invention also aims to provide a fluid dispensing device which can be produced and assembled at low cost, while guaranteeing a perfect seal, even in the case of the use of propellant gases such as HFA gases.
- the present invention further aims to provide a method of assembling a fluid dispenser device, for which the assembly is facilitated and therefore less expensive.
- the present invention therefore relates to a fastening element of a dispensing member, such as a pump or a valve, on the neck of a container containing a product to be dispensed, with the interposition of a neck seal comprising a inner edge and an outer edge for sealing at the neck of the container, said fixing element comprising a receiving part for receiving said dispensing member and a fixing part for fixing to said neck of the container, said fixing element further comprises a holding part for receiving and holding said neck seal, said annular seal being held in said holding part of the fixing element only at its inner edge.
- a dispensing member such as a pump or a valve
- the holding part of the fastening element comprises an annular recess consisting of a bottom wall, an outer side wall and an inner side wall, said inner side wall comprising retaining means for cooperating with said inner edge of the neck seal to fix it inside said recess.
- said inner side wall of the annular recess makes an angle less than 90 ° * relative to said bottom wall, such that the diameter of said inner side wall, with respect to the central axis of the element fixing, is variable, with at its end opposite said bottom wall, a diameter greater than the diameter of the inner edge of the joint.
- the difference in diameter between the ends of said inner side wall is such that, once placed in the recess, the seal is not prestressed.
- said neck seal is inserted into said recess before assembly of the fixing element.
- said fixing part includes crimping, snap-fastening or screwing means.
- the present invention also relates to a device for dispensing a fluid product, comprising a dispensing member, such as a pump or a valve, mounted on the neck of a container containing a product to be dispensed, with the interposition of a seal. neck to seal at said neck of the container, said dispensing member being mounted on said neck by means of a fixing element.
- the dispensing member is a metering valve and the fixing element is a capsule, preferably metallic, which is fixed to the neck by crimping.
- the present invention also relates to a method of fixing a dispensing member, such as a pump or a valve, to the neck of a container containing a product to be dispensed, with the interposition of a neck seal to ensure sealing at the level of said neck of the container, comprising the following steps:
- a fastening element comprising a receiving part for fixing to said dispensing member, a fixing part for fixing to said neck of the container, and a holding part for receiving and fixedly fixing said neck seal
- said step of assembling the dispensing member in the receiving part can, as a variant, be carried out after said step of placing the neck seal in said holding part and / or after said step of fixing the unit. the fastener / seal on the container.
- said dispensing member is a metering valve
- said fixing element is a capsule, preferably metallic, and said steps of assembling and fixing are carried out by crimping.
- FIG. 1 is a schematic sectional view of a device for dispensing a fluid product according to an advantageous embodiment of the invention
- FIG. 2 is a schematic sectional view, showing more particularly the fastening element according to the advantageous embodiment of the invention.
- the dispensing device comprises a dispensing member, such as a metering valve 20, which is mounted on the neck 31 of a container 30, by means of a fixing element 10, in particular a crimpable capsule.
- the metering valve 20 can be arbitrary and will therefore not be described in more detail below. It is fixed in a receiving part 11 of the capsule 10 which receives and fixes the valve body, in particular by snap-fastening or crimping.
- the capsule 10 also includes an attachment portion 12 for attaching to said neck 1 of the container 30, said attachment portion 12 may include crimping, latching or screwing means or any other known means. In the example shown in the figures, these are crimping means.
- the fixing element 10 further comprises a holding part 13 which is intended to receive and fix the neck seal 1 which is placed between the fixing element 10 and the neck 31 of the container for seal at this location.
- Said holding part 13 is made in such a way that the neck seal 1, which is preferably annular and which has an inner edge 2 and an outer edge 3, is fixedly held in said holding part 13 only at its edge interior 2.
- said retaining part 13 comprises an annular housing 14 intended to receive said seal 1, said annular recess 14 consisting of a bottom wall 15, an annular side wall outer 16 and an inner annular side wall 17.
- said inner side wall 17 comprises retaining means which are adapted to cooperate with said inner edge 2 of the neck seal 1 to keep it fixed inside of said recess 14.
- the present invention provides a fixing element, in particular a crimping cap, in which the neck seal 1 can be assembled before the final assembly on the neck 31 of the container.
- the means for retaining the inner side wall 17 are formed by a deformation of said inner wall 17, so that the latter makes an angle of less than 90 ° relative to said bottom wall 15.
- the diameter of said inner side wall 17 gradually increases from a minimum diameter which is formed at said bottom wall 15 to a diameter maximum achieved at the opposite end.
- the maximum diameter of said inner side wall is preferably slightly greater than the diameter of the inner edge 2 of the neck seal 1, so that, after having been inserted into the housing 14, said seal 1 is fixedly held in said housing only by said inner side wall.
- the diameter of the inner side wall 17, at the bottom wall 15, is equal to or slightly less than the diameter of the inner edge 2 of the seal, so that when the seal is inserted into the housing 14, there is no is not prestressed.
- the seal 1 is held in the housing in the housing 14 only at its inner edge 2, the bottom wall 15 and the outer side wall 16 of the housing 14 may have variable dimensions so that the element of fixing 10 can be achieved with relatively high manufacturing tolerances without influencing the positioning of the seal 1 in said retaining portion 13.
- This also allows large manufacturing tolerances of the seal 1, which in particular allows the use of manufacturing methods inexpensive joints, such as cutting the joint from a strip of suitable material, rather than molding.
- molded seals can also be used with the fastener of the present invention.
- the manufacture of the fastening element 10 as shown in Figures 1 and 2 is particularly simple.
- this can first be carried out in a conventional manner with an interior wall 17 that is straight, then this interior wall can be deformed, for example by fitting a cone inside. of the capsule.
- a relatively large difference in diameter d between the ends of the inner side wall 17 can be obtained, without there therefore being any major problem due to a possible undercut inside the housing. 14 due to the inclination of the inner side wall 17.
- the fastening element allows great manufacturing tolerances for the neck seal, this can be made by any suitable method, in any suitable material, depending on the subsequent application of the joint.
- the neck seal can be cut, molded or even overmolded, that is to say injected directly into the capsule, which allows the use of different materials, such as elastomers, in especially nitryl, butyl or chloroprene, thermoplastic elastomers (TPE), EPDM, etc.
- elastomers in especially nitryl, butyl or chloroprene, thermoplastic elastomers (TPE), EPDM, etc.
- TPE thermoplastic elastomers
- EPDM thermoplastic elastomers
- An advantage of the invention is that it provides a simple fixing element which can be used in a large number of very varied applications with very different sealing requirements (device with or without propellant gas, etc.).
- a fixing element 10 also makes it possible to carry out the method of fixing or assembling the device in a simpler and therefore less costly manner.
- the neck seal 1 according to the invention comes into place in the housing 14 of the capsule 10, before it is fixed to the container, to form a fixing element / seal unit which will then be assembled, in particular crimped on the neck of the container.
- the prior placement of the seal in the capsule guarantees proper positioning of the seal, and eliminates the need for an additional piece, such as a seal positioning ring, which is necessary, especially when it is desired to use a seal neck area reduced.
- the fixing of the dispensing member in the receiving wall 11 of the fixing element 10 can be carried out before or after the installation of the seal 1 in the housing 14 of the fixing element 10, and it could even be considered to fix the dispensing member in said receiving part 1 1, after installation of the fixing element / seal unit on the container neck.
- the present invention therefore makes it possible, by very simple and inexpensive means, to assemble a dispensing device comprising a neck seal with reduced surface area, thus limiting as much as possible the interactions with the product contained inside the container, without the need for 'use an additional part, and penne ttant to achieve the seal and / or the fixing element with relatively high manufacturing tolerances.
- the deformation of the fastening element 10 at the level of the internal lateral wall 17 also provides an additional advantage in that this deformation makes it possible to limit the dead volume inside the device, thus making it possible to guarantee a better distribution of the whole. of the product inside the container.
