Definitions
- the present invention relates to a fluid dispenser pump, as well as a fluid dispenser device incorporating such a pump.
- Fluid product dispensing pumps are well known in the art.
- the present invention relates more particularly to pumps in which the return spring of the pump is not in contact with the product dispensed by this pump.
- the spring is therefore placed in a chamber inside the pump body which is isolated from the product but which contains air.
- the movable element of the pump which cooperates with this spring moves by compressing the spring and the presence of air can pose a problem on the ease or reliability of use of the pump. .
- the present invention therefore aims to provide a fluid dispensing pump which is safe and reliable to use, while being simple and inexpensive to manufacture and assemble.
- the present invention therefore relates to a fluid dispenser pump, comprising a pump body containing a metering chamber defined between a high piston sliding in an upper part of the pump body and a low piston sliding in a lower part of the body pump, said low piston cooperating with a spring disposed in said lower part of the pump body, characterized in that the spring is isolated from any contact with the fluid, the lower part of the pump body comprising means for taking up air allowing the entry and / or exit of air when the pump is actuated, isolation means being provided to prevent the penetration of fluid product into said air intake means.
- said air intake means are formed by a hole made in the lower part of the pump body.
- said insulation means comprise an external envelope disposed around said pump body.
- an air passage is defined between said casing and said pump body, said air passage being connected to the vent hole of the pump.
- the vent hole includes a filter adapted to filter the incoming air.
- said envelope is fitted around the pump body, said air passage being defined by at least one groove formed in the external wall of the pump body and / or in the internal wall of the envelope.
- said envelope comprises a radial flange forming a seal with a reservoir on which the pump is assembled.
- said radial flange forms a neck seal.
- said envelope comprises a sock forming a seal with the external wall of the pump body.
- said sock is elastically deformable to allow air passing out of the interior of the pump body to pass through said air intake means.
- the present invention further relates to a fluid dispenser device comprising a pump as defined above, said pump being mounted on a reservoir by means of a fixing ring or capsule.
- the pump of the present invention comprises a pump body 10 which defines a metering chamber 20 between a high piston 30 and a low piston 40.
- the high piston 30 slides in an upper part of the pump body 11 and the low piston 40 slides in a lower part 12 of the pump body.
- the low piston 40 is mounted floating inside the pump body and cooperates with a spring 50 which is mounted on a bottom wall of the pump body 10 and which forms the return spring of the pump.
- this spring 50 is completely isolated from the fluid product which is distributed by the pump. This means that no product enters the spring chamber, that is to say in the lower part of the pump body in which the spring is located.
- the present invention provides for making air return means 15 in the lower part 12 of the pump body to allow the entry and / or exit of air during pump actuation.
- air intake means 15 are produced in the form of a hole made in the lower part 12 of the pump body.
- insulation means 60 are provided to prevent the penetration of fluid product inside the lower part of the pump body, to guarantee that the spring 50 does not come into contact with the fluid product.
- the total absence of contact between the spring, generally metallic and the fluid to be dispensed is particularly important in the case of certain pharmaceutical products which risk being altered by contact with this spring.
- the insulation means 60 are advantageously produced in the form of an external envelope which is fitted around the pump body and which covers the hole 15 to prevent the fluid product from entering it.
- the external envelope has a shape identical to that of the pump body so that the fitting is achieved with a contact over the entire wall, an air passage 61 being however formed between the pump body 10 and the outer casing 60, this air passage being connected to the vent hole 100 of the pump.
- the vent hole is arranged in the upper part of the pump, at the level of the pump seal 80 which forms the seal between the pump and the fixing ring or capsule 70, which is suitable for mounting the pump on a tank (not shown).
- the seal 80 is a filter seal, that is to say that the air which enters the pump for replace the volume of product dispensed passes through said filter 80 which removes all bacteria and / or impurities which could affect the quality of the product.
- the envelope 60 comprises a radial flange 65 which is adapted to form the seal with the neck of the reservoir (not shown).
- this radial flange 65 can even form the neck seal of the pump.
- the vent hole 100 is directly connected to the air passage 61 produced between the pump body and the outer casing 60, and it is therefore necessary to provide air passage means, allowing this air vent inside the pump.
- This is preferably achieved by means of a sock 62 preferably produced at the lower end of the external envelope 60, this sock forming on the one hand the seal with the external wall of the pump body 10, but being elastically deformable to let vent air through.
- the present invention makes it possible to guarantee a total absence of contact between the return spring of the pump 50 and the fluid product, while allowing safe and reliable operation of the pump since the air contained in the chamber of the spring 50 can freely circulate as a function of the displacement of the low piston 40.
- the isolation means in particular the external envelope provides a seal against the entry of product in contact with this spring, so that the objectives of the present invention are achieved by this very simple and inexpensive means constituted by the casing 60.
- the present invention further limits the number of component parts to achieve the objective of the invention.
