Definitions
- the present invention relates to a fluid or powder dispenser.
- the preferred fields of application of such a distributor are in particular, but not exclusively, pharmaceutical, cosmetic or perfumery.
- Some dispensers of fluid or powdered product of the prior art generally comprise a dispensing member defining a metering chamber in communication with one or more reservoir (s) of fluid or powder and on the other hand with an organ actuating said dispensing member.
- Parts of the dispenser intended to contain the product or to be in contact with the product are most often made of plastic materials.
- the use of plastic materials often involves problems of adhesiveness or sticking of product on the walls of the parts of the dispenser in contact with the product and in particular at the level of the metering chamber.
- such a product adhesivity on the walls of the metering chamber results in problems of reproducibility of doses distributed following actuation of the dispenser member.
- the document WO / 02051483 proposes depositing a fluorinated coating on the surface by means of "plasma-coating” technology or using either fluorinated polymers (such as PTFE) and other fluorinated families (such as PFA, PVDF, etc.) or to associate fluorinated agents with commonly used materials (polyester resins and acetal) to create fluorinated compounds.
- fluorinated polymers such as PTFE
- other fluorinated families such as PFA, PVDF, etc.
- the present invention aims to overcome the aforementioned problems and to propose a solution other than that disclosed in the aforementioned document.
- the present invention also aims to provide a dispenser of fluid or powder product simple and inexpensive to manufacture. Another object of the present invention is to provide a dispenser permitting a regular and reproducible product distribution with each actuation of the dispenser member.
- the subject of the present invention is therefore a fluid or powder product dispenser comprising at least one reservoir capable of containing fluid or powdery product to be dispensed, a dispensing member, such as a pump or a valve, an actuating member capable of to actuate said dispensing member, a dispensing orifice through which fluid or powdered product is dispensed, at least a portion of the dispenser in contact with the fluid or powdery product being made of an anti-adhesion material comprising at least one polymer or a intrinsically dissipative copolymer of electrostatic charges (IDP). Examples of IDPs are disclosed in EP-I 304 355.
- IDPs are implemented in the field of packaging electronic components and in particular are used to produce hard disk drive components which require to remain permanently clean, that is to say without ionic extractibles.
- IDPs have so far never been used to solve the problem of fluid or powdery material sticking in the field of fluid or powder product distribution. The invention will now be more fully described in the detailed description which follows.
- the present invention applies to all types of fluid or powder dispenser.
- the present invention can be applied to distributors incorporating a dispensing member such as a pump or a valve.
- a dispensing member such as a pump or a valve.
- the dispensing member actuated by means of an actuating member, makes it possible to release at a dispensing orifice a quantity of product contained in a metering chamber in communication with one or more reservoirs ( s) of product.
- the operation of such dispensing members is known and therefore will not be further described.
- the present invention is also particularly suitable for dry powder inhalers in which the parts in contact with said powder, in particular the reservoir (s) and / or the metering chamber and / or the various conduits through which the powder to be dispensed passes, tend to fix the powder.
- Fixing or bonding fluid or powder product generally results from electrostatic phenomena related to an imbalance of electrical charges between the (s) material (s) with which (s) are manufactured distributors and the product to be dispensed.
- a part of the dispenser advantageously one or more of the elements in contact with the fluid or powder, such as the reservoir (s), the dosing chamber, the dispensing member, the dispensing member, actuation and all of the ducts leading to the dispensing orifice, is made of an anti-adhesion material comprising at least one polymer or an intrinsically dissipative copolymer of electrostatic charges, commonly called IDP.
- IDP intrinsically dissipative copolymer of electrostatic charges
- All of the IDPs are concerned by the present invention.
- the dissipative properties of IDPs come essentially from their molecular structure. This structure can thus accept ions freely flowing along the molecular chains in order to limit electrostatic charges on the surface.
- polyetherester, polyetherurethane, polyetheresteramide and / or polyacrylic acid can be used as IDP.
- the distributor parts in contact with the fluid product with an anti-adhesion material comprising an alloy of at least one IDP with at least one other polymer.
- an anti-adhesion material comprising an alloy of at least one IDP with at least one other polymer.
- such alloys have the function of offsetting the relatively weak robustness of the IDP.
- said at least one polymer combined with IDP generally has advantageous mechanical properties.
- the alloy obtained will have both the anti-adhesion properties of the IDP and the mechanical properties of said at least one polymer alloyed with IDP.
- Such alloys thus make it possible to obtain a polymeric alloy that is more resistant and that can be injected-molded or extruded without risk of damage.
- said at least one other polymer may be chosen from the following polymers: polymethyl methacrylate (PMMA), polybutylene terephthalate (PBT), polyacetal (POM), polyethylene glycol (PETG), polyvinylchlorare
- PVC polyamide
- PA polycarbonate
- PS polystyrene
- SAN acrylonitrile butadiene styrene
- HDPE high density polyethylene
- LDPE low density polyethylene
- PSU polysulfone alloy
- PET polyethylene terephthalate
- TPUR thermoplastic polyurethane elastomer
- PPS polyphenylene sulfide
- PES polyethersulfone
- TPE polyester thermoplastic elastomer
- TPE polyester thermoplastic elastomer
- PPO polyphenylene ether oxide
- PPO polyetherimide
- PEEEK polyetherketone
- RTPU saturated styrenic elastomer
- SEBS saturated styrenic elastomer
- SBS unsaturated styrene elastomer
- TEO elastomer olefin thermoplastic
- TSV vulcanized styrenic elastomer
- the material according to the invention has a resistivity of between approximately 1 and 10 12 ohm / sq in order to effectively limit the phenomena of sticking of the product.
- This range of resistivity value particularly low thus prevents the anti-adhesion material is easily loaded electrostatic charges and therefore limits the bonding of the fluid or powder.
- the present invention provides an advantageous and effective solution for eliminating the problem of sticking fluid or powder, especially in the dispensing chamber of a dispenser.
- the material used makes it possible to guarantee a more even distribution of product with each actuation of the dispensing member by reducing the mass variability of the active ingredient dispensed or inhaled.
- This invention is therefore particularly, but not exclusively, particularly interesting for the distribution of pharmaceutical formulations.
