  • the immobilization in rotation of the nozzle 4 relative to the neck 2 is guaranteed thanks to the cooperation of shapes between lug 14 and cutout 13.
  • the channel 28 is located opposite the side opening 15 and it is isolated from the latter by the tubular skirt 9.
  • the dispensing head 1 is thus closed, the valve 34 isolated from the product, and any product departure prevented.
  • the user When using the device for the first time, the user must rotate the capsule 5 around the X axis to bring the lateral opening 15 opposite the channel 28.
  • Product departure can be caused by overwriting the container 3 when the latter is made of a material flexible plastic or by any other pressurizing device of product inside the container.
  • the valve 34 deviates from its seat on the pivoting cover 7 under the effect of the pressure of the product upstream in the dispensing orifice 29.
  • valve 34 After dispensing a dose of product, the valve 34 resumes its rest position in which it closes the orifice distribution 29 thanks to its own elasticity, the return of the valve in its rest position being facilitated if necessary by the effect of suction accompanying the return of the container 3 in its initial conformation.
  • the initial dimensions of the valve molded can be such that a clearance is made between the valve and its seat on the cover 7 to take account of the swelling of the material of the valve in contact with the product during use.

  • Leclapet presents in top view as shown in Figure 10 a general shape in ⁇ and its edge free cleaning with the adjacent edge of the cover a gap g between 0.1 and 0.2 mm. This interstice allows the air intake.
  • valve 66 is made of the same material as the cover but with a different color, by bi-injection molding of material. he can also be made by bi-injection in a material more flexible than that used to mold the rest of the cover. Finally, the valve can be made separately and attached and then fixed by any known means on the cover.
  • the invention allows forms of distribution heads with undercuts and authorizes greater freedom in choosing the general aesthetics of the conditioning.
  • the manufacturing of the dispensing head is made more easy thanks to the invention, in particular by the fact that it allows make the valve (s) without too much difficulty.
  • the invention also makes it possible to reduce the possibilities of access to the interior of the capsule of foreign bodies such as sand.
  • the material bridges 17, 17 ', 17' 'or 59 advantageously connecting the end piece and the capsule, able to hold the latter in a position in which it isolates the distribution channel from inside the container, avoid that during storage, before first use, the valve made of elastomer material is not contact with product and swelling of the valve material.
  • the invention advantageously makes it possible to produce shapes with undercut for the distribution head with a minimum of material, the shell 24 of the capsule may be thin.
  • Figures 1 to 10 correspond to examples of realizations comprising a nozzle to be fixed in a mouth of a container.
  • the air intake can of course be carried out by a not completely sealed closure of the dispensing orifice product in the absence of product distribution, or during the return air, or by an air return valve not integral with the valve opening under the pressure of the product to be dispensed.
