Definitions

  • the invention relates to a dosing head for “Err” vessels under “Cae” pressure “Err” continuous valve.
  • This piece “Err” reported “Err” has a passage connecting the hollow rod of the continuous valve “Err” a metering chamber which is itself connected by another passage “Err” the expulsion nozzle.
  • a valve is provided, the closure of which is caused by the pressure of the finger on the valve head, and the opening by the release of this pressure.
  • all the “Err” elements of the dosing cap are made of rubber, that is - “Err” - to say “Err” deformable in all directions, it is quite difficult to obtain, on the one hand, a regular “Err” dosage, on the other hand a good “Err” efficiency of the valve.
  • the realization of the valve is delicate “Err”, as is that of the metering chamber “Err” wall “Err” movable.
  • the pressure of the finger on said piston moves it down in order to close the passage connecting the central chamber “Err” to the expulsion nozzle and to apply the "Cae” valve seat to the passage connects "Err” the hollow rod which allows the filling of the metering chamber when the “Cae” insert is also moved down on the hollow rod.
  • the release of the finger pressure allows the piston to be returned to the upper position by elastic means and therefore the emptying of the metering chamber by the passage leading to the expulsion nozzle.
  • the object of the invention is therefore to propose a dosing head which adapts in a simple and removable manner to a pressure vessel “Err” continuous valve, while being of particularly simple, therefore inexpensive “Err” embodiment, and in ensuring a perfect seal of the assembly.
  • the subject of the invention is a dosing head for pressure vessels with continuous valve comprising:
  • cup adapted to be in leaktight relation with the pressure vessel, said cup having a central plate provided with an axial orifice for the continuous valve body,
  • a sheath-end piece consisting of a central chamber "Err” bottom surrounding the central foot of the membrane support, a radial end piece and a cylindrical skirt, characterized in that said "Cae" valve seat of the foot center of the membrane support is applied directly to the end of the hollow control rod of the continuous valve to fill the dosing "Err” bell during the dosing phase, and moves away from it to connect the "Err” bell “Err” dosing unit for the nozzle during the expulsion phase.
  • the hollow control rod of this valve is the hollow rod of the latter
  • the hollow rod for controlling this valve is constituted by a connector in the form of a hollow rod
  • the seal is arranged on the bottom of the central chamber of the sheath-nozzle
  • the bottom of the central chamber has two arches, the free end of which rests on the central plate of the cup, acting as a spring to return the dosing head to its exhaust position,
  • the bottom of the central chamber carries two arcs, the free end of which rests on a disc of the fitting, acting as a spring to return the dosing head to its exhaust position,
  • the dosing head fits onto the rod 5.
  • This dosing head comprises the following elements: a dosing “Err” bell “Err” ll defining the volume of the dosing liquid “Err”; a “Err” membrane 12 made of rubber or elastomer, acting as an elastic wall of the metering chamber; a membrane support “Err” 13; and a gait-tip "Err” "Err” l7.
  • the membrane support “Err” 13 is fixed, for example by snap-fastening, in the “Err” dosing bell “Err” ll; it has a central leg “Err” l4 provided with an axial passage “Err” l5 ending “Err” its base in the form of a valve seat “Err” l6. “Err” u- “Err” del of the valve seat “Err” l6, the central foot “Err” l4 is extended by fingers “Err” l.
  • the central foot "Err” l4 carries “Err” its periphery an annular rib “Err” l9, “Err” triangular section for example, on which is clipped the "Err” sheath-tip "Err” l7.
  • the “Err” sheath-tip “Err” l 7 is made up of: a central chamber “Err” l “Err” and cylindrical 2O surrounding the central foot “Err” l4 of the membrane support “Err” l3; a “Err” 2l radial nozzle; and a cylindrical “Err” or skirt 22 long enough for its free edge to slide under the "Err” flange 3 so that "Err” holds the dosing head in place on the container. "Err” this effect, the free edge of the "Err” sheath 22 has an outer rib 23.
  • the "Err" sheath 22 still carries, “Err” outside, a tab “Err” tearable 24, which serves as a stop on the "Err” flange 3 to prevent the dosing head from sinking. When this safety tab is removed, the dosing head can be actuated.
  • the central chamber 2O has an annular bottom 25, which the rod 5 crosses.
  • a sealing gasket 26 is disposed on which the fingers "Err" l are supported. Therefore, the seal 26 slides tightly on the valve stem 5.
  • the bottom 25 of the chamber 20 carries "Err" the outside two arcs 27 whose free end rests on the central plate 2 of the “Err” cup l and which act as springs to accompany the upward movement of the dosing head when the finger pressure is removed.
  • the operation of the dosing head according to the invention is as follows. First of all, the dosing head is placed on the container fitted with its continuous valve “Err” hollow rod 5. This positioning is done by light pressure on the bell “Err” 17, so that the outer rib 23 which borders the "Err” sheath 22 crosses the "Err” flange 3. The corresponding downward movement of the dosing head is stopped by the safety tab 24 which comes into abutment on the "Err" flange 3. During this positioning of the dosing head, the seal 26 has come to slide on the hollow rod 5, as shown in the figure "Err” l.
  • valve seat "Err" 16 which is supported on the rod “Err” 5 prevents any passage of the pressurized liquid towards the nozzle "Err" 21.
  • the product in the container is in liquid form and is under pressure.
  • the product is put "Err” atmospheric pressure and can then be in a form other than liquid. It is thus possible to expel an aerosol, a foam, or a cream for example.
  • a foaming product a liquid dosage is carried out and a foam is distributed whose volume, or quantity, is proportional to the volume of the bell.
  • a cup “Err” l has been represented identical to “Err” that of the figure “Err” l, but mounted on a container equipped with a continuous valve of female type, that is to say “Err” - say not having a hollow rod “Err” 5 like that of the figure “Err” l.
  • a 3O connector such as that shown in FIG. 2.
  • This 3O connector is presented as a hollow rod whose head , housed in the cylindrical chamber 2O, has a peripheral rib 32 ensuring its maintenance above the "Cae” joint 26.
  • the connector 3O carries a disc “Err” 3l on which come to bear the arcs 27.
  • the connector 3O is provided with an axial passage 33 passing through it completely, and it has “Err” its lower end at least one notch 34.
  • FIG 3 is shown an alternative embodiment of the "Err” Sealing on the hollow rod “Cae” of Figure “Err” l.
  • the seal 26 is deleted.
  • the "Err" fingers 18 extend to the bottom 25 of the cylindrical chamber 20.
  • the bottom 25 carries a lip 47, annular, molded, which rubs on the rod "Err" 5 to seal.
