Definitions

  • the present invention relates to a device for sampling and dispensing a viscous product, without air intake.
  • the high viscosity of all these products has the disadvantage of causing a decrease in the rate of return of the bottle during the emptying of the bottle. It is known that these products can be removed from their container with a pump associated with a flask without air intake, airless type. It is necessary to use either airless piston flasks or airless pocket flasks. Indeed, these systems make it possible to restore the viscous products more effectively.
  • the bag systems may lose their return performance and may use a dip tube, which will greatly slow down the operation of the pump. . Indeed, when the bag is full of product, a traditional dip tube absorbs the product by its lower end, but the pressure drop is high.
  • the solution would be to increase the diameter of the dip tube. But the problem would remain whole because the volume of product and air to convey, become more important, would also increase the number of strokes.
  • the sampling and dispensing device 1 generally designated in the figures comprises on the one hand a pumping member (3) arranged, by its base (8), at the open end (4) of a rigid container (5). associated with a retractable flexible inner pouch (6) for receiving the product (2), and on the other hand a plunger tube (7) connected by its upper end (7a) to a corresponding part (3a) of the organ pumping, so that the upper end (7a) is partially immersed in the product (2) and that the lower end (7b) free is fully immersed in the product (2).
  • the opening angle of the longitudinal slot (9) of the second open bottom portion (7B) of the tube (7) represents a circular sector whose apex angle ( ⁇ ) is between 45 and 120 °.
  • the width "a" of the slot is optimized to allow the product to easily enter the tube through the slot, without allowing the introduction of the bag by suction at the end of restitution.
  • the first and second portions (7A, 7B) of the dip tube (7) are obtained distinctly from each other, the upper one having a closed circumference (7A) being obtained by molding a plastic material with the base (3a) of the pumping member (3), and with which cooperates by interlocking the lower part with open circumference (7B).
  • the second portion (7B) is inserted within the first portion (7A).
  • the second portion (7B), slit along its entire length, is fitted outside the first portion (7A).
  • the second part (7B) further comprises a first open reinforcement ring (71) which extends circumferentially and with the same sector angle as the second part (7B) in an area which overlaps the first part (7A). ).
  • the first reinforcing ring (71) serves to increase the stiffness of the second portion (7B) to obtain a reinforced tightening on the first portion (7A).
  • the second portion (7B) has a second reinforcing ring (72) symmetrically with respect to a transverse plane.
  • the presence of the second reinforcing ring (72) is not functional, but allows to avoid the orientation of the second part during assembly with the pump (3).
  • Each end of the second part (7B) is identical and can be fitted on the first part (7A).
  • the sector angle of the second part (7B) can be chosen, as in the first embodiment, for example between 45 and 120 °, for example at 90 °.
  • the second part (7B) comprises a plurality of reinforcing rings at each end.
