Abstract
Description
La présente invention concerne un distributeur de produit fluide ou pulvérulent selon le préambule de la revendication 1.The present invention relates to a fluid or powder dispenser according to the preamble of claim 1.
Les domaines d'application privilégiés d'un tel distributeur sont notamment mais pas exclusivement la pharmaceutique, la cosmétique ou la parfumerie.The preferred fields of application of such a distributor are in particular, but not exclusively, pharmaceutical, cosmetic or perfumery.
Certains distributeurs de produit fluide ou pulvérulent de l'art antérieur comportent généralement un organe de distribution définissant une chambre de dosage en communication d'une part avec un ou plusieurs réservoir(s) de produit fluide ou pulvérulent et d'autre part avec un organe d'actionnement dudit organe de distribution. Les parties du distributeur destinées à contenir du produit ou à être en contact avec du produit sont la plupart du temps réalisées en matériaux plastiques. Or, l'utilisation de matériaux plastiques implique bien souvent des problèmes d'adhésivité ou de collage de produit sur les parois des parties du distributeur en contact avec le produit et notamment au niveau de la chambre de dosage. Ainsi, une telle adhésivité de produit sur les parois de la chambre de dosage se traduit par des problèmes de reproductibilité des doses distribuées suite à un actionnement de l'organe de distribution.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. However, 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. Thus, 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.
Pour réduire le collage du principe actif dans la chambre de dosage, le document
La présente invention a pour but de surmonter les problèmes susmentionnés et de proposer une solution autre que celle divulguée dans le document précité.The present invention aims to overcome the aforementioned problems and to propose a solution other than that disclosed in the aforementioned document.
La présente invention a également pour but de fournir un distributeur de produit fluide ou pulvérulent simple et peu coûteux à fabriquer.The present invention also aims to provide a dispenser of fluid or powder product simple and inexpensive to manufacture.
La présente invention a encore pour but de fournir un distributeur permettant une distribution de produit régulière et reproductible à chaque actionnement de l'organe de distribution.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.
La présente invention a donc pour objet un distributeur de produit fluide ou pulvérulent comprenant au moins un réservoir apte à contenir du produit fluide ou pulvérulent à distribuer, un organe de distribution, tel qu'une pompe ou une valve, un organe d'actionnement apte à actionner ledit organe de distribution, un orifice de distribution par lequel du produit fluide ou pulvérulent est distribué, au moins une partie du distributeur en contact avec le produit fluide ou pulvérulent étant réalisée en un matériau anti-adhésion comprenant au moins un polymère ou un copolymère intrinsèquement dissipatif de charges électrostatiques (IDP). Des exemples d'IDP sont notamment divulgués dans le document
L'invention sera maintenant plus amplement décrite dans la description détaillée qui suit.The invention will now be more fully described in the detailed description which follows.
La présente invention s'applique à tous types de distributeur de produit fluide ou pulvérulent. En particulier, la présente invention peut s'appliquer à des distributeurs incorporant un organe de distribution telle qu'une pompe ou une valve. Généralement, l'organe de distribution, actionné à l'aide d'un organe d'actionnement, permet de libérer au niveau d'un orifice de distribution une quantité de produit contenue dans une chambre de dosage en communication avec un ou plusieurs réservoir(s) de produit. Le fonctionnement de tels organes de distribution est connu et ne sera donc pas davantage décrit.The present invention applies to all types of fluid or powder dispenser. In particular, the present invention can be applied to distributors incorporating a dispensing member such as a pump or a valve. Generally, 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.
La présente invention convient aussi particulièrement aux inhalateurs de poudre sèche dans lesquels les parties en contact avec ladite poudre, notamment le ou les réservoir(s) et/ou la chambre de dosage et/ou les différents conduits par lesquels transite la poudre à distribuer, ont tendance à fixer la poudre. Dans le cas des inhalateurs fonctionnant avec une valve contenant un gaz propulseur pour distribuer le produit, ce problème de collage est accentué par la présence d'un gaz propulseur, tels que les gaz HFA (HFA-134a ou HFA-227), à l'origine de la création d'une surpression au sein du distributeur. Cette surpression a tendance à plaquer la poudre contre les parois des différentes parties du distributeur et ainsi à favoriser le collage de la poudre sur ces parois, notamment au niveau de la chambre de dosage dans le cas d'une valve doseuse. Cet effet a été amplifié par l'utilisation des gaz HFA en remplacement des gaz CFC nocif pour l'environnement.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. In the case of inhalers operating with a valve containing a propellant gas for dispensing the product, this gluing problem is accentuated by the presence of a propellant gas, such as HFA (HFA-134a or HFA-227), at the same time. origin of the creation of an overpressure within the distributor. This overpressure tends to press the powder against the walls of the various parts of the dispenser and thus to promote the bonding of the powder on these walls, especially at the level of the metering chamber in the case of a metering valve. This effect has been amplified by the use of HFA gases as a substitute for CFC gases harmful to the environment.
La fixation ou le collage de produit fluide ou pulvérulent résulte généralement de phénomènes électrostatiques liés à un déséquilibre de charges électriques entre le(s) matériau(x) avec le(s)quel(s) sont fabriqués les distributeurs et le produit à distribuer.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.
Selon l'invention, une partie du distributeur, avantageusement un ou plusieurs des éléments en contact avec le produit fluide ou pulvérulent, tel que le ou les réservoir(s), la chambre de dosage, l'organe de distribution, l'organe d'actionnement et l'ensemble des conduits menant à l'orifice de distribution, est réalisée en un matériau anti-adhésion comprenant au moins un polymère ou un copolymère intrinsèquement dissipatif de charges électrostatiques, communément appelé IDP. L'ensemble des IDP sont concernés par la présente invention. Les propriétés dissipatives des IDP viennent essentiellement de leur structure moléculaire. Cette structure peut ainsi accepter des ions circulant librement le long des chaînes moléculaires pour ainsi limiter les charges électrostatiques en surface. A titre d'exemples non limitatifs, le polyétherester, le polyétheruréthane, le polyétheresteramide et/ou l'acide polyacrylique peuvent être utilisés en tant qu'IDP.According to the invention, 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. 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. By way of non-limiting examples, polyetherester, polyetherurethane, polyetheresteramide and / or polyacrylic acid can be used as IDP.
D'autre part, il est également possible de réaliser les parties du distributeur en contact avec le produit fluide avec un matériau anti-adhésion comprenant un alliage d'au moins un IDP avec au moins un autre polymère. Bien souvent, de tels alliages ont pour fonction de compenser la relativement faible robustesse de L'IDP. Pour ce faire, ledit au moins un polymère combiné à l'IDP présente généralement des propriétés mécaniques avantageuses. Ainsi, l'alliage obtenu sera doté à la fois des propriétés anti-adhésion de l'IDP et des propriétés mécaniques dudit au moins un polymère allié à l'IDP. De tels alliages permettent ainsi d'obtenir un alliage polymérique plus résistant et pouvant être injectés-moulés ou extrudés sans risque de détériorations. Pour former de tels alliages, ledit au moins un autre polymère peut être choisi parmi les polymères suivants : le polyméthylméthacrylate (PMMA), le polybutylène téréphtalate (PBT), le polyacétal (POM), le polyéthylène glycol (PETG), le polyvinylchlorure (PVC), le polyamide (PA), le polycarbonate (PC), le polystyrène (PS), le styrène acrylonitrile (SAN), l'acrylonitrile butadiène styrène (ABS), le polyéthylène haute densité (PEHD), le polyéthylène basse densité (PEBD), l'alliage polysulfone (PSU), le polyéthylène téréphtalate (PET), l'élastomère thermoplastique polyuréthane (TPUR), le polyphénylène sulfure (PPS), le polyéthersulfone (PES), l'élastomère thermoplastique polyester (TPE), le polyphénylène éther oxide modifié (PPO), le polyétherimide (PEI), le polyétheréthercétone (PEEK), le polyuréthane thermoplastique rigide (RTPU), l'élastomère styrénique saturé (SEBS), l'élastomère styrénique insaturé (SBS), l'élastomère thermoplastique oléfinique (TEO), l'élastomère styrénique vulcanizè (TPV), le polyméthylpentène (PMP), le perfluoroalkoxy (PFA), l'éthylène térafluoroéthylène (ETFE), le polyvinylidène fluorure (PVDF), le polymère à cristaux liquides (LCP), l'éthylène propylène fluoré (FEP), le polyphtalamide (PPA), le polyéthercétonecétone (PEKK), le polyimide thermoplastique (TPI), le polyamide hautes températures (NHT), le polystyrène syndiotatique (SPS), le polytriméthylène téréphtalate (PTT). Toutefois, cette liste de polymères ne doit pas être considérée comme étant limitative, tous polymères aptes à être combinés audit au moins un IDP pouvant être utilisés.On the other hand, it is also possible to make 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. Often, such alloys have the function of offsetting the relatively weak robustness of the IDP. To do this, said at least one polymer combined with IDP generally has advantageous mechanical properties. Thus, 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 more resistant polymeric alloy and that can be injected-molded or extruded without risk of deterioration. To form such alloys, said at least one other polymer may be chosen from the following polymers: polymethylmethacrylate (PMMA), polybutylene terephthalate (PBT), polyacetal (POM), polyethylene glycol (PETG), polyvinylchloride (PVC ), polyamide (PA), polycarbonate (PC), polystyrene (PS), styrene acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), high density polyethylene (HDPE), low density polyethylene (LDPE) ), polysulfone alloy (PSU), polyethylene terephthalate (PET), thermoplastic polyurethane elastomer (TPUR), polyphenylene sulfide (PPS), polyethersulfone (PES), thermoplastic polyester elastomer (TPE), polyphenylene Modified Ether Oxide (PPO), Polyetherimide (PEI), Polyetheretherketone (PEEK), Rigid Thermoplastic Polyurethane (RTPU), Saturated Styrenic Elastomer (SEBS), Unsaturated Styrenic Elastomer (SBS), Thermoplastic Elastomer olefinic (TEO), vulcanized styrenic elastomer (TPV), polymethylpentene (PMP), perfluoroalkoxy (PFA), ethylene terafluoroethylene (ETFE), polyvinylidene fluoride (PVDF), liquid crystal polymer (LCP), fluorinated ethylene propylene (FEP), polyphthalamide (PPA), polyetherketoneketone (PEKK), thermoplastic polyimide (TPI), high temperature polyamide (NHT), syndiotatic polystyrene (SPS), polytrimethylene terephthalate (PTT). However, this list of polymers should not be considered as limiting, any polymers capable of being combined with said at least one IDP can be used.
Avantageusement, le matériau selon l'invention présente une résistivité comprise entre environ 10-3 et 109 Ωm (1 et 1012 ohm/sq) de façon à limiter efficacement les phénomènes de collage du produit. Cette gamme de valeur de résistivité particulièrement faible évite ainsi que le matériau anti-adhésion se charge facilement en charges électrostatiques et par conséquent limite le collage du produit fluide ou pulvérulent.Advantageously, the material according to the invention has a resistivity of between approximately 10 -3 and 10 9 Ωm (1 and 10 12 ohm / sq) so as 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.
Par conséquent, la présente invention propose une solution avantageuse et efficace destinée à éliminer le problème de collage de produit fluide ou de poudre, notamment au niveau de la chambre de dosage d'un distributeur. Ainsi, le matériau utilisé permet de garantir une distribution plus régulière de produit à chaque actionnement de l'organe de distribution en réduisant la variabilité en masse du principe actif distribué ou inhalé. Cette invention est donc notamment, mais pas exclusivement, particulièrement intéressante pour la distribution de formulations pharmaceutiques.Therefore, 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. Thus, 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.
