Definitions

  • the piston is a visible and unsightly mechanical element, perceived as trivially functional, and does not correspond to the image of certain prestigious brands of cosmetic products.
  • the objective of the present invention is to eliminate or at least mitigate this effect.
  • the problem to be solved is therefore to hide the piston, to make it invisible or even to make it a mobile aesthetic element, within the tank.
  • the lateral ends of the piston consist only of the outer sealing line and the outer guide points. Only these lateral ends will be in contact with the reservoir, and will therefore be visible from the outside by the dispenser user. In the end, there will only be a single contact line and contact points that will be visible to the user through the reservoir.
  • the fluid dispenser comprising a piston of the present invention no longer forms an unsightly sealing ring visible from the outside of a tank.
  • the sealing means define a single external sealing line. This single line is thus very discreet compared to the two rings of the prior art.
  • the exterior guidance points are very discreet, and barely visible to the user through the tank.
  • the invention relates to a fluid dispenser without air intake comprising a reservoir capable of storing the fluid and housing a piston as described above, the reservoir having a bottom and a neck located opposite the bottom, said sealing means of the piston being in contact with an inner wall of the reservoir, forming a contact line, and the free ends of the legs being in contact with the inner wall of the reservoir, forming contact points.
  • This dispenser is characterized in that the legs of the piston are oriented towards the neck of the reservoir: in this case, the legs are immersed in the fluid.
  • Dispensers without air intake called “airless” (absence of air in the tank 10) are equipped with so-called “follower” pistons. They are in contact with the product and rise with each dispensing under the effect of the depression in the tank induced by this dispensing.
  • follower pistons so-called “follower” pistons. They are in contact with the product and rise with each dispensing under the effect of the depression in the tank induced by this dispensing.
  • the piston 1 is composed in particular of sealing means 2 and guide means 3. These sealing means 2 and these guide means 3 have ends which define an external envelope of the piston 1, capable of coinciding with the internal volume of a reservoir 10 into which the piston 1 is introduced.
  • the outer casing of the piston 1 will also be cylindrical in shape.
  • the sealing means 2 of the piston 1 make it possible to divide the reservoir 10 into two sealed zones relative to each other.
  • the sealing means 2 allow the fluid product contained in a first zone, for example above the piston 1, not to bypass the piston 1 and not to reach the second zone located in this case below the piston 1.
  • the guide means 3 of the piston 1 make it possible to maintain the piston 1 in a stable position transversely inside the reservoir 10, and allow the piston 1 to move axially inside the reservoir 10 while remaining in stable positions inside the reservoir 10 over its entire travel.
  • FIGS. 1a to 1d illustrate a first embodiment of the piston 1 for the fluid product dispenser according to the invention.
  • piston 1 has a square shape, that is to say square with the four rounded corners.
  • Piston 1 has a central axis X as defined in the Figure 1d .
  • Legs 4 develop around this X axis and are located in the same plane P transverse to this X axis.
  • the piston 1 may be produced using tri-injection, with the rounded parts 6 of the legs 4 made of a third material which may be more flexible than the rest of the guide means 3 in order to absorb the radial dimensional dispersions of the inner walls 14 of the reservoir 10 inside which it moves.
  • the radial dimensional tolerances may be less drastic in this case.
  • PETG polyethylene terephthalate glycol
  • the piston 1 in the second embodiment of the piston 1 for the fluid dispenser according to the invention, shown in Figures 2a and 2b , the piston 1 consists of three assembled parts.
  • a connecting piece 7 mounted by force in the guide means 3.
  • this connecting piece 7 is of square shape, and has external dimensions slightly larger than the internal dimensions of the base 8.
  • the base 8 is a hollow part. The base 8 thus accommodates within it, by forcing, the connecting piece 7.
  • the sealing means 2 are clamped between the connecting piece 7 and the base 8.
  • the piston 1 in the third embodiment of the piston 1 for the fluid dispenser according to the invention, shown in Figures 3a and 3b , the piston 1 consists of a single-injected part to which a toric or quadrilobe seal 2 is added. This seal 2 constitutes the sealing means 2.
  • the piston 1 consists of a single rigid part, preferably made of PP (polypropylene) produced by single injection, and comprising a groove 9 in which the O-ring 2 is inserted, sealing the piston 1 against the internal wall of the reservoir 10.
  • PP polypropylene
  • Such an O-ring or quadrilobe seal for example made of silicone, has the advantage of providing a good elastic response whatever the local curvature of the tank 10 (i.e. round or square or round, triangular or other, and with rounded corners or not), both on a straight part and on a rounded part.
  • the piston 1 has the same general external appearance, and has an improved restitution rate thanks to the cube 5 projecting from the base 8. This restitution rate is further improved thanks to the presence of a complementary female shape 11 to the guide means 3 of the piston 1 present at the upper end 13 of the reservoir 10, that is to say opposite the bottom 12 of the reservoir 10.
  • Such a complementary form 11 is visible at Figures 4a to 4c .
  • the upper end 13 of the reservoir 10 is provided with this complementary female shape. It comprises hollows and recesses in which the legs 4, their rounded ends 6, as well as the cube 5 projecting from the piston 1 are housed. Thanks to this complementarity, there is almost no more fluid trapped between the piston 1 and the upper part 13 of the reservoir 10 when the piston 1 reaches the end of its travel as can be seen in the figure.
  • Figure 4e is .
  • a flat pump with a deformable membrane fixed flat on top of the tank 10, and which therefore does not penetrate into the tank 10, is used.
  • piston 1 has a round profile and no longer square.
  • its base 8 is truncated in shape and it has four legs 4 extending obliquely from the base 8, and distributed equidistant from each other all around the base 8.
  • This base 8 has a cylindrical central orifice extending into a central orifice of truncated cone shape 18 widening towards the upper end of the base 8, that is to say in the direction of the top 13 of the reservoir 10.
  • This piston 1 is capable of being housed in a complementary female form 11 provided for this purpose, not in the upper part 13 of the reservoir 10 but in a ring 15 mounted in the upper part 13 of the reservoir 10 and in which it is possible to fix a fluid product distribution pump.
  • This ring 15 enters the reservoir 10.
  • This female complementary shape 11 comprises a central truncated cone-shaped part which fits into the central truncated cone-shaped orifice 18 of the base 8, and comprises four hollow wings 16 inside which the legs 4 of the piston 1 can fit.
  • the central cylindrical orifice is provided to fit the pump body which is immersed in the reservoir 10.
  • the ninth embodiment of the piston 1 for the fluid dispenser according to the invention is close to the eighth embodiment of the Figure 9 .
  • microbiocidal properties of the material can also be obtained by contacting the product with a microbiostatic agent, for example by using a metallic material such as a copper or zinc alloy or a material comprising at least one polyolefin loaded with such metallic particles or having undergone a surface treatment by fluorination, zinc plating or copper plating.
  • a metallic material such as a copper or zinc alloy or a material comprising at least one polyolefin loaded with such metallic particles or having undergone a surface treatment by fluorination, zinc plating or copper plating.
  • the microbiocidal properties of the material can also be obtained by irradiating the piston with radiation of a suitable wavelength, in particular by means of a material which exhibits photoluminescence properties after exposure to external light.
  • the material can be based on at least one polyolefin loaded with at least one additive capable of emitting photoluminescent radiation which has a wavelength of between 250 and 260 nanometers, and in particular 254 nanometers, which corresponds to the order of magnitude of sterilizing ultraviolet radiation.
