Definitions
- the present invention relates to a device for dispensing a fluid product, and more particularly such a device operating with a pump without air intake.
- a device for dispensing a fluid product and more particularly such a device operating with a pump without air intake.
- fluid product distribution devices comprising a reservoir containing the product, generally a liquid, a pump, said pump being fixed. on said tank by means of a turner and / or a fixing ring.
- the pump operates without air intake, but in this case there is the problem of the vacuum created inside the tank.
- the object of the present invention is to provide a device for dispensing a fluid product which does not have the abovementioned drawbacks.
- the present invention thus aims to provide a device of • a fluid dispenser with a pump operating without air recovery, called airless pump, said device for balancing the vacuum inside the tank without involving contamination of product remaining in the tank and without complication of the manufacture and assembly of the device and therefore of its cost.
- the present invention also aims to provide a fluid dispensing device which works ef fi ciently with any type of tank, shape or any material.
- the present invention also aims to provide such a fluid product distribution device which prevents any alteration of the product contained in the reservoir while guaranteeing perfect distribution of the latter on each actuation.
- the present invention therefore relates to a device for dispensing a fluid product comprising a product reservoir, a dispensing member, such as a pump operating without air intake, a spinner fixedly supporting said pump, said spinner being fixed on said reservoir for a fixing ring, at least part of said spinner being made of an air-permeable plastic material.
- said spinner is made in one piece with said fixing ring.
- the air-permeable plastic material allows air to pass into the interior of the tank but blocks the passage of bacteria.
- the air-permeable plastic material comprises thermoplastic polymers.
- the air-permeable plastic material has a filler.
- the filler is chalk, talc or silicone.
- said spinner includes a window made of air-permeable plastic material, said window being overmolded in said spinner made of non-permeable material.
- FIG. 1 is a schematic view showing a first variant of a spinner according to the present invention
- - Figure 2 is a view similar to Figure 1 showing a second variant of tourette according to the present invention
- - Figure 3 is a view similar to Figure 1 showing a third variant of tourette according to the present invention.
- the fluid dispenser device comprises a reservoir of product (not shown), which can be of any shape and made of any material, a dispenser member 10, in particular an airless pump, that is to say - say operating without air intake, and a tower 20 which fixedly supports said pump 10.
- This tower 20 is then fixed to the neck of the tank by means of a fixing ring 30.
- the tourette 20 and the ring 30 are produced in the form of two different parts, while in the embodiment shown in FIG. 2, the tourette 20 and the ring 30 form a single piece.
- the fixing ring 30 can be of any suitable type, and in particular of the type to snap on (fig. 1), screw on (fig. 2) or crimp (fig 3).
- At least part 21 of the spinner 20 is made of a plastic material permeable to air.
- the depression created inside the tank can be compensated by an air flow, represented schematically by the arrow A in the figures, which passes through said spinner 20.
- the part 21 of the tower 20 through which the air passes is located in the intermediate part located between the part 22 of the tower 20 which the pump 10 supports and the part 23 of the tower 20 which is fixed to the ring attachment 30. It is therefore at least this part 21 which must be made of plastic material permeable to air.
- FIG. 3 shows a spinner 20 made of non-permeable plastic material and comprising a molded window 21, said window being made of air-permeable plastic material.
- the invention therefore allows the use of a pump of known type which does not need to be modified, as well as the use of any tank of known type which also does not need to be modified. 'be changed.
- the only part to be modified in the fluid product dispensing devices used today is said spinner 20, which is a small part, very easy to manufacture.
- This tourette can for example be manufactured by molding, in particular using a process injection / blowing, or by a bi-injection process.
- a particularly advantageous characteristic of the invention is that said air-permeable pie according to the present invention can be produced in the same machine and / or the same mold as that making the pies used until now, by simply modifying the plastic material supplied to said machine.
- the solution proposed by the present invention is therefore particularly economical and allows very simple and therefore very inexpensive manufacture and assembly of the various constituent parts of the dispensing device, no machine of the assembly line having to be modified.
- the air-permeable plastic material constituting said drum 20 can advantageously consist of thermoplastic polymers, such as polyolefins, PVC or technical polymers, advantageously comprising a filler.
- This filler intended to increase the diffusion of air can be in particular chalk, talc or silicone.
- the advantage of these plastic materials is that they allow air to pass while retaining contaminating agents such as bacteria, thus making it possible to avoid any deterioration of the product contained inside the tank.
- the air-permeable plastic materials which can be used to make the spinner according to the invention these can in particular be those used to make the walls of the bottle in document EP-0771 734. This document is therefore included in the present description for reference for this particular feature.
- the present invention therefore makes it possible to provide a particularly advantageous and economical solution for solving the problem of avoiding contamination of the product contained in a dispensing device operating with an airless pump.
