  • the cutout has, along the longitudinal and central axes, an inclined linear profile, said profile being decreasing from an end situated in the vicinity of the hinge zone to an end opposite the hinge zone .
  • the valve which can be used to equip the dispenser according to the invention is advantageously a conventional recess valve.
  • This valve can be a male valve comprising an emerging control rod communicating via a connection pin of the mobile part with the dispensing orifice. It is also possible to use a stemless female valve; in this case, the rod is secured to the movable part, in communication with this valve.
  • the movable part is advantageously in the form of a domed, flattened cap acting as a clean push button for controlling, via the rod, the opening of the valve.
  • the top of the cap is formed, for example, by an inclined plane, constituting a bearing surface on which the user places his index finger, in order to distribute a dose of product.
  • this push button comprises a conduit for conveying the product towards the dispensing orifice.
  • This duct comprises two segments in the extension of one another respectively defining an axial channel and a radial channel, bent relative to each other and forming between them an obtuse angle ⁇ .
  • the axial channel of this conduit is formed by a hollow central pin carried by the internal face of the push-button adapted to be connected to the valve stem.
  • the central pin has a height along the longitudinal axis, such that its free end is substantially at the same level as the hinge zone.
  • the dispensing orifice can be equipped, if necessary, with a spray nozzle, when the product to be dispensed is a liquid.

  • the small base of the trapezium forms, in particular, the pivot axis of the hinge zone and is oriented, advantageously, perpendicular to the axis of the reservoir.
  • the two lateral sides of the trapezium thus converging towards the hinge area, are delimited by two inclined branches of a cut separating the mobile part from the fixed part.
  • the ends opposite to the hinge zone of said branches open into a middle part of the cutout.
  • This middle part is oriented substantially perpendicular to the axis of the tank, and is located on the periphery of the movable part.
  • This middle part of the cutout has, in particular, an arcuate shape. This cut allows the movable part to pivot relative to the fixed part around the axis of the hinge zone.
  • an angle ⁇ is formed between each branch and the middle part.
  • this angle ⁇ is an angle between 70 ° and 160 °.
  • the angle ⁇ is an obtuse angle.
  • This hinge zone by which the mobile part is connected to the fixed part, is preferably situated in a plane passing through the axis of the tank and the axis center of the dispensing orifice. According to the invention, this hinge zone is at a level, along the axis of the tank, corresponding substantially to the level of the connection means. More particularly, the connection means consists of the valve stem and the pin of the mobile part. In particular, the level of the hinge zone is just at the height of the emerging end of the valve stem.
  • the hinge zone can be constituted by two struts oriented perpendicular to the axis of the reservoir and carried by the movable part, these struts cooperating with two complementary cylindrical bores carried by the fixed part of the dispensing head. However, preferably, the hinge zone is a film hinge formed by a part of flexible material of less thickness than the rest of the material forming the movable part.
  • the dispensing head thus formed then forms a monobloc assembly (fixed part - movable part and film hinge). From the industrial point of view, this monobloc embodiment allows easy molding requiring only low assembly costs of the head on the tank.
