Definitions
- the present invention relates to a fluid dispenser device improved, and in particular such a device eliminating any risk of contamination of the product contained in it.
- Document US-5,727,715 discloses a filter system which can be arranged to the outside of the pump fixing ring on the tank. Sealing with the pump is made by means of an O-ring placed around the actuating rod of the pump. This implementation is complicated because relatively unreliable, and risks impede the actuation of the pump. The size of the O-ring must be very precisely determined, which can be problematic.
- the present invention aims to provide a product distribution device fluid allowing filtration of the incoming air, which does not have the drawbacks above.
- the present invention also relates to a device for distributing fluid product for filtering incoming air, in which air filtration is carried out without modification of the parts forming the device, and which adapts to all existing distribution systems.
- the present invention also aims to provide such a device for distribution of fluid allowing filtration of the incoming air, operating from reliable and safe, and simple to make and assemble.
- the present invention therefore relates to a product distribution device fluid according to claim 1.
- 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 the level of said opening.
- the filtration element makes an integral part of said external organ.
- the filtration element is said flexible membrane which is filtering and breathable.
- said external member is snapped onto said fixing element.
- the dispensing head comprises a shutter at the level of the dispensing orifice, so that all of the outside air coming in 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.
- a device for dispensing of fluid product comprising a reservoir 10 and a dispensing member, such that a precompression pump 20 in this example, which is fixed on the reservoir 10 to using a fixing element 40, in this case a crimped ring.
- the tank, the pump and the fixing ring can be of any known type, in particular standard, and will therefore not be described more fully below.
- the device comprises a filtration element 60 or 75 for filter the air entering reservoir 10 to replace the dose of product expelled during the previous actuation of the device.
- This incoming air passes through a hole vent 50 which according to the invention is arranged outside the tank and the element of attachment 40, and the filter element 60 or 75 is disposed near said vent hole 50.
- this filtration element 60 is produced in the form of an annular filter 60.
- This filter 60 is preferably kept close to the vent hole 50, outside the ring fixing 40, by an external member 70, which can be fixed to the fixing element 40, in particular by snap-fastening as shown in FIG. 1.
- the member external 70 comprises a fixing part 71, here latching means, and a membrane part 75 not permeable to air and tightly fixed to the rod 25 for actuating the pump 20.
- Said external member 70 further comprises a opening 78 forming the vent hole 50 and against which the annular filter 60 is disposed.
- said filter 60 is wedged by the external member 70 between it and the outside of the fixing ring 40, at the level of said opening 78.
- the membrane part 75 is flexible to allow movement thereof with the actuating rod 25 without risk of leakage or loss of tightness at the junction of the external member 70 with rod 25.
- FIG. 2 there is shown an alternative embodiment of the first embodiment of FIG. 1, in which the external member 70 is no longer engaged but fitted around the tower of a known precompression pump.
- said external member maintains an annular filter 60 against a opening 78 forming the vent hole of the dispensing device.
- the filter is held only by the external member 70, in a annular depression.
- the head of distribution 30 is shown diagrammatically, and advantageously comprises a two-part structure.
- the dispensing head has an internal part 35, about tubular and defining the dispensing orifice 33, which is fixed so tight on the actuating rod 25 of the pump.
- the flexible membrane portion 75 of the external member 70 can in this case be fixed on this internal part 35 of the head distribution rather than directly on the actuating rod 25, as shown in Figure 1.
- FIG. 4 another alternative embodiment is shown. of the first embodiment of the invention, in which the external member 70 maintains 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 into which is inserted from the outside, said annular filter 60.
- the dispensing head 30 is also shown as being formed in two parts, however slightly different from Figure 3.
- the internal part 35 is snapped onto the rod actuation 35 of the pump to prevent its intentional tearing or accidental.
- the membrane portion 75 of the external member is again fixed so sealed on said internal part 35 of the dispensing head.
- the dispensing head is provided with a shutter 38 at the orifice of distribution 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 distribution orifice 31, the fixing of the internal part 35 of the dispensing head on the actuating rod 25 of the pump prevents it from being torn off and therefore contamination at the level of said actuating rod 25, and the filter 60 filters the air which enters for replace the dose of product previously expelled.
- FIG. 5 there is shown a second embodiment of the present invention.
- the distribution system as a whole is similar to that shown in Figure 3, but the external member 70 has a membrane portion flexible filter 75 acting as a filter element of the device.
- said flexible membrane portion 75 is made of a suitable material which leaves pass air while filtering out microbes, bacteria and other contaminants.
- said membrane 75 is tightly fixed to the internal part 35 of the head distribution, but it could just as easily be attached directly to the rod pump 25.
