Definitions
- the present invention relates to a device for dispensing an improved fluid, and in particular such a device eliminating any risk of contamination of the product contained therein.
- the problem of contamination of the product contained in a dispensing device has been posed for a long time, and many solutions have been proposed to remedy this problem.
- the solution which is generally adopted consists in having a filter to filter the incoming air replacing the dose. of product previously dispensed This filter is generally placed at the vent hole of the pump, which means that so-called standard pumps which do not have such a filter have to be modified
- Another solution has been to place the filter between the reservoir and the ring fixing the pump to the tank
- This solution also requires modifying an element of the device, namely the fixing ring, which must on the one hand receive and filter the filter and on the other hand have a single opening acting as event hole All the solutions proposed so far have therefore required the modification of one or more component parts of the device distribution system to perform this incoming air filtration function
- the object of the present invention is to provide a device for dispensing a fluid product allowing filtration of the incoming air, which does not have the above-mentioned drawbacks.
- the subject of the present invention is also a device for dispensing a fluid product making it possible to filter the incoming air, in which the filtration of the air is carried out without modification of the parts forming the device, and which adapts to all the devices existing distribution
- the present invention also aims to provide such a fluid dispensing device for filtering the incoming air, operating reliably and safely, and simple to make and assemble.
- the present invention therefore relates to a device for dispensing a fluid product, comprising a reservoir of product and a dispensing member, such as a pump, actuated by an actuating rod connected to a dispensing head for selectively dispensing said product.
- said distribution member being fixed to said tank by means of a fixing element
- the distribution device comprising an air vent located outside the tank and of the fixing element, an air filtration element being disposed near said air vent, outside said fixing element, said filtration element being fitted on or near the air vent by means of an external member fixed on the fixing element and / or the reservoir, said external member comprising a fixing part which is fixed on the fixing element of the dispensing device and a flexible membrane part connected in leaktight manner to said ti actuation age and / or part of said dispensing head
- said filtration element is an annular filter
- said external member has an opening disposed between these two parts, a filter being held by the external member at said opening.
- the filtration element forms an integral part of said external member.
- the filtration element is said flexible membrane which is filtering and permeable to air.
- said external member is snapped onto said fixing element
- the dispensing head comprises a shutter at the dispensing orifice, so that all of the outside air coming into contact with the product contained in the dispensing device passes through the filtration element, preventing any contamination of said product before, during and after actuation of the device.
- Figure 1 is a schematic cross-sectional view of part of a fluid dispenser device according to a first embodiment of the invention
- Figure 2 is a view similar to that of Figure 1 showing a variant of the first embodiment of the present invention
- Figure 3 is a schematic cross-sectional view of a device similar to that of Figure 1
- Figure 4 is a schematic cross-sectional view of another variant of the first embodiment of embodiment of the present invention
- - Figure 5 is a cross-sectional view of a fluid dispenser device produced according to a second embodiment of the present invention
- a fluid dispenser device comprising a reservoir 10 and a dispensing member, such as a precompression pump 20 in this example, which is fixed on the reservoir 10 using a fixing element 40, in this case a crimped ring.
- the reservoir, the pump and the fixing ring can be of any known
- the device comprises a filtration element 60 or 75 for filtering the air entering the tank 10 in replacement of the dose of product expelled during the previous actuation of the device.
- This incoming air passes through a hole d 'event 50 which according to the invention is arranged outside the reservoir and the fixing element 40, and the filter element 60 or 75 is arranged near said vent hole 50
- this filtration element 60 is produced in the form of an annular filter 60
- This filter 60 is preferably held near the vent hole 50, outside the fixing ring 40 , by an external member 70, which can be fixed to the fixing element 40, in particular by encetting as shown in FIG.
- the external member 70 comprises a fixing part 71, here means of snap, and part of membrane 75 not permeable to air and fixed in leaktight manner to the actuating rod 25 of the pump 20
- Said external member 70 further comprises an opening 78 forming the vent hole 50 and against which the annular filter 60 is arranged
- said filter 60 is comce by the external member 70 between it and the outside of the fixing ring 40, at the level of said opening 78
- the membrane portion 75 is flexible to allow movement of the latter with the actuating rod 25 without risk of leakage or loss of sealing at the junction of the external member 70 with the rod 25
- FIG. 2 there is shown an alternative embodiment of the first embodiment of FIG.
- the dispensing head 30 is shown diagrammatically, and advantageously comprises a structure in two parts Amsi , the dispensing head has an internal part 35, approximately tubular and defining the distribution orifice 33, which is fixed in sealed manner to the actuating rod 25 of the pump
- the flexible membrane part 75 of the external member 70 can in this case be fixed on this internal part 35 of the dispensing head rather than directly on the actuating rod 25, as shown in FIG. 1
- u is represents yet another alternative embodiment of the first embodiment of the invention, in which the external member 70 holds the annular filter 60 on its outer side against its opening 78 forming the hole air vent 50 of the device
- the external member 70 is advantageously provided with an annular radial recess in which the annular filter 60 comes to merge from the outside.
- the dispensing head 30 is also shown as being formed in two parts, but in a slightly different manner from FIG. 3
- the internal part 35 is snapped onto the actuating rod 35 of the pump to prevent its intentional or accidental tearing
- the part of membrane 75 of the external member is again fixed in a sealed manner on said internal part 35 of the dispensing head
- the dispensing head tion is provided with a shutter 38 at the dispensing orifice 31, which guarantees a total absence of contamination of the product contained in the device before, during and after use thereof.
- the shutter prevents any entry of air at the level of the dispensing orifice 31, the fixing of the internal part 35 of the dispensing head to the actuating rod 25 of the pump prevents it from being torn off and therefore a contamination at the level of said actuating rod 25, and the filter 60 ensures the filtration of the air which enters to replace the dose of product previously expelled
- FIG. 5 it is a second embodiment of the present invention.
- the distribution device as a whole is similar to that shown in FIG. 3, but the external member 70 comprises a portion of flexible filtering membrane 75 acting as a filtration element of the device to do this, said flexible membrane portion 75 is made of a suitable material which lets air pass while filtering microbes, bacteria and other contaminating agents Said membrane 75 is fixed so tight to the internal part 35 of the dispensing head, but it could just as easily be fixed directly to the actuating rod 25 of the pump.
