Definitions

  • This present invention concerns a valve seal and a device for the dispensing of a fluid product that includes such a seal.
  • ethylene propylene (EP) and ethylene propylene diene monomer (EPDM) turned out to be appropriate materials.
  • Ethylene propylene and ethylene propylene diene monomer have also proven to be appropriate materials for solving this problem.
  • Document EP-0 969 069 describes a valve seal that is intended for a fluid product dispenser that includes EPDM as well as a mineral filler that includes magnesium silicate and/or Kaolin.
  • the purpose of these mineral fillers is to improve the properties of the seal, and in particular the aspects concerning its sealing properties.
  • the purpose of this present invention is to supply a valve seal that includes a different mineral filler, in order to obtain good characteristics for the seal, in particular those aspects concerning the effectiveness of its sealing properties, its elastic properties, and the manufacturing process of the seal.
  • Another objective of this present invention is to provide such a valve seal with improved sliding properties and with a reduced extractible substances leeching rate.
  • a further objective of this present product is to supply such a valve seal which is simpler and less costly to manufacture than the previously known valve seals.
  • the subject of this present invention is therefore a valve seal that is intended for a fluid product aerosol dispenser, characterised in that the said seal includes an elastomer which is based upon ethylene propylene (EP) and/or ethylene propylene diene monomer (EPDM), and a mineral filler that is based upon quartz (SiO 2 ) and Kaolinite (Al 4 [(OH) 8 Si 4 O 10 ]).
  • EP ethylene propylene
  • EPDM ethylene propylene diene monomer
  • mineral filler that is based upon quartz (SiO 2 ) and Kaolinite (Al 4 [(OH) 8 Si 4 O 10 ]).
  • the mineralogical composition of the mineral filler includes between 65% and 95%, preferably about 80%, of quartz, and between 5% and 35% preferably about 20%, of Kaolinite.
  • the chemical composition of the mineral filler includes between 3% and 15%, preferably about 8%, of Al 2 O 3 , and between 75% and 95%, preferably about 87%, of SiO 2 .
  • the mineral filler has a pH greater than 6, preferably between about 7 and 8.
  • the mineral filler has an average particle size of between 1.5 and 4 microns, preferably about 2.2 microns.
  • the said seal before its assembly into a fluid product aerosol dispenser, is subjected to a surface chlorination treatment.
  • the said seal is immersed in a solution containing water, hydrochloric acid and bleach.
  • Another objective of this present invention is a measuring-out valve for a fluid product aerosol dispenser that includes at least a valve seal as described above.
  • This present invention also has as its objective a fluid product aerosol dispenser that includes a reservoir containing a fluid product and a propellant gas, and a valve, preferably a measuring-out valve, mounted on the said reservoir, where the said valve includes at least a valve seal as described above.
  • the said valve includes a valve element sliding in a valve body with the interposition of a valve seal, where the said valve seal is made as described above.
  • the said propellant gas includes HFC-134a gas and/or of the HFC-227 gas.
  • the reservoir also contains alcohol, ethanol in particular.
  • Another objective of this present invention is a manufacturing process for a valve seal intended for a fluid product aerosol dispenser, characterised in that the process includes the following stages:
  • the said surface chlorination treatment includes immersing the seal in a solution containing water, hydrochloric acid and bleach.
  • the mineral filler of this present invention has a structure which is both granular and lamellar. This results in improving the elastic properties of the seal, improving the effectiveness of the sealing properties of the seal, and also simplifies the manufacturing process of the said seal.
  • a material that is particularly suitable to be used in accordance with this present invention is Sillitin, which is a natural mixture of quartz and kaolinite. This material has never been used in the manufacture of valve seals, in particular of the type of dynamic valve seal in which the valve element slides.
  • Sillitin contains much less Al 2 O 3 and much more SiO 2 in relation to Kaolin.
  • the granular and lamellar structure of Sillitin results in improving the effectiveness of the seal in relation to a seal with the same elastomer, such as EP or EPDM for example, but a mineral filler composed of Kaolin.
  • the neutral pH can limit the interactions between the seal and the active ingredient contained in the fluid product to be dispensed.
  • a seal that includes EP and/or EPDM, and a mineral filler that includes Sillitin is particularly suitable for use with HFC gases. It is also particularly suitable to be used with HFC gases in the presence of alcohol, and ethanol in particular.
  • the seal can also be subjected to a surface chlorination treatment.
  • This treatment is used in particular to reduce the electrostatic character of the seal. The properties of the seal, in particular its sliding quality, are therefore ameliorated.
  • This treatment is also used to reduce the leeching of extractible substances, and therefore limits the risk of interaction with the active product.
  • this surface treatment can be effected by immersing the seal in a solution containing water, hydrochloric acid and bleach. This leads to the formation of chlorine which attaches itself to the surface of the seal.
