  • the user When first used, as shown in figure 2 , and in order to cause the dispensing of the cosmetic product from inside the container 4, the user exerts, for example with one of his fingers, a pressure on the dome 221 of the diaphragm 20.
  • the pressure exerted causes a depression of the diaphragm 20.
  • Said pressure is understood here as a force advantageously exerted parallel to the direction of depression of the diaphragm 20, that is to say orthogonal to the flat portion 129 of the pump body 10 and to it .
  • the diaphragm 20 is designed to sink under the effect of said pressure exerted by the user.
  • the tongue of the inlet valve 222 is designed and arranged so that the pressure exerted by the air contained in the first portion 19a of the diaphragm 20 plates said tongue of the intake valve 222 against the outlet orifice 122 of the intake passage 120.
  • the inlet valve 222 thus continues to obstruct the inlet passage 120.
  • the compressed air inside the first part 19a then flows through the recess 128 of the pump body 10 and passes from the first 19a to the second part 19b of the interior space.
  • the pressure exerted against the second portion 211 of the diaphragm causes the lifting thereof by elastic deformation.
  • said second portion 211 By lifting, said second portion 211 carries with it the finger-shaped protuberance of the dispensing valve 201, thus releasing the inlet orifice 111 of the dispensing passage 115.
  • the air then rushes inside. of said dispensing passage 115 and is expelled outwardly of the pump 1 through the outlet port 117 of said dispensing passage 115. This outward air flow continues until the pressure is reached. equalizes between the interior space 19 of the diaphragm and the outside.
  • the second portion 211 of the diaphragm 20 then resumes its rest position in which the dispensing valve obstructs the inlet orifice 111 of the dispensing passage 115.
  • the dome 221 of the diaphragm 20 returns to its rest position.
  • the volume of the interior space 19 of the dispensing pump 1 increases. This increase in volume causes a decrease in the pressure in the interior space 19.
  • the protuberance of the dispensing valve 201 remains pressed against the inlet orifice of the dispensing passage 115.
  • the pressure inside the container 4 becomes higher than the pressure in the inner space 19 of the pump 1.
  • the tongue of the inlet valve 222 is deformed and a portion of said tongue, whose free end, moves towards the inner space 19 of the pump 1
  • at least a portion of the tongue of the inlet valve 222 departs from the outlet orifice 222 so that it opens, at least partially, it.
  • the cosmetic product contained in the container 4 then moves through the intake passage 222 and then fills, at least partially, the inner space 19 of the pump 1. This filling takes place until the pressures equalize between the intake passage 120 and the inner space 19 of the pump 1.
  • this displacement of cosmetic product creates inside the container 4 a depression.
  • the atmospheric pressure that is to say the outside pressure of the dispensing device becomes greater than the pressure inside the container 4
  • the pressure inside the air inlet channel 330 in its portion between the distal end 336 of the air channel 330 and the inner portion 334 of the air inlet valve 338 , becomes less important than the pressure between said inner portion 334 of the air inlet valve 338 and the outlet orifice of the air inlet channel 330.
  • This pressure differential on either side of the internal portion 334 of the air inlet valve 338 causes deformation of the extension of the inner portion 334 of the air inlet valve 338.
  • said extension is deformed so that the inner portion 334 is more obstructs the air inlet channel 330 and thereby allows a return of air into the container.
  • One or more pressures on the diaphragm 20 thus allow priming of the pump 1.
  • a new pressure of the user on the diaphragm 20 allows the distribution of the cosmetic product according to a mechanism identical to that described above allowing the expulsion of air from said interior space 19 of the pump 1 to the outside. The difference is that this time it is the cosmetic product initially contained in the container 4 and no longer air that is expelled through the passage. This depression also allows the filling of the interior space 19 with a new dose of cosmetic product at the moment when the diaphragm 20 resumes its rest position.
  • the pump body 10 and the diaphragm 20 are designed in different materials.
  • the flexible membrane of the diaphragm 20 is made of plastic elastomer.
  • the pump body 10 is itself made of polypropylene.
  • the diaphragm 20 is advantageously secured to the pump body 10 by welding.
  • the dispensing pump 1 comprises a welding bead 213, for example made of polypropylene.
  • the welding bead 213 is designed in a material identical to that in which the pump body 10 is designed.
  • Said welding bead 213 is designed to be disposed at the periphery of the diaphragm between the pump body 10 and said periphery. of the diaphragm 20.
  • the plane portion 129 is provided on its inner surface with two positioning ribs 119 in the form of a semicircle. These ribs 119 are designed to facilitate the positioning of the diaphragm 20 relative to the pump body 10.
  • the dispensing pump further comprises a reinforcing armature 214.
  • Said stiffening armature 214 is then disposed between the diaphragm 20 and the welding bead 213.
  • the flexible membrane of the diaphragm is then subjected to the reinforcing armature 214, which is located at its periphery.
  • said reinforcing armature 214 is overmolded on the flexible membrane.
  • Said stiffening frame 214 is example in the same material as that constituting the pump body 10.
  • the reinforcing armature 214 is here made of polypropylene.
  • the well 111 is provided with a ring 102 protruding from the flat portion 129. Unlike the first embodiment, it is said ring 102 serves as a seat for the protrusion of the outlet valve 201.
  • the air inlet valve 338 is made of polyethylene.
  • the pump 1 is provided with a device for dethroning a mounting operator and / or a user during assembly of the dispensing pump 1 on the container 4.
  • the outer skirt 311 of the base 30 of the body pump 10 is provided at its free end with notches 312.
  • Said notches 312 are designed to facilitate an appropriate positioning, particularly angularly and / or in depth, of the pump 1 vis-à-vis the container 4.
  • the said notches 312 are for example two in number and diametrically opposite one another.
  • Said notches 312 are here of substantially rectangular shape.
  • Said slots 312 are for example designed to cooperate mechanically with lugs arranged at the neck of the container 4 and / or on it.
  • the pump body 10 is advantageously provided with two reinforcing ribs 107 which extend perpendicular to both the flat portion 129 and the circular plate 301. Said ribs 107 extend parallel to each other and on both sides of the slump 128 and the intake passage 120.
