Definitions

  • the present invention relates to a dispensing and closure system intended to be disposed at the end of a container, in particular a flexible tube containing a liquid or pasty product which is evacuated by pressure on said tube.
  • liquid or pasty such as creams, gels, emulsions, an anti-bacterial preservative.
  • the anti-bacterial action takes place only in close contact with the surface of the container and not at heart.
  • the present invention proposes to remedy all these drawbacks, ie at the level of the pump (airless), at the level of the protective mechanism of the head.
  • the invention relates to a distribution and closure system intended to be disposed at the end an elastically deformable container, in particular a flexible tube comprising a liquid or pasty product, which is evacuated by pressure on said tube, this system consisting of a valve comprising two concentric elements, one of which forms a cylindrical valve mobile having at its upper central part an opening defining a peripheral seat and the other of which forms a cylindrical body derived from a connecting plate with the tube and whose closed upper end of said cylindrical body is capable of cooperating with the closing with the seat of said movable valve, the two elements defining between them an annular space through which the product passes, during a manual pressure exerted on the tube, consequently causing a direct action of the product on the valve acting on it in opening, against an elastic return member, so as to escape the product of the tube, when n presses on it and automatically close the opening when released, without possible return to the inside of the product already released.
