  • the course of the coupling part 42 and of the movable element 28 along the axis 24 is for example greater than 6 mm and is in particular between 2 mm and 8 mm. This large course authorizes a dispensing of a substantial volume of product, for example greater than 2 ml, by a single actuating of the movable element 28.
  • the cosmetic product is conveyed through the movable element 28, in the cover
  • the dispensing duct 44 is deformed slightly by bending and the nozzle 74 pivots slightly inside the dispensing opening 33.
  • the user presses on the visual marking 140 situated opposite the second lateral wall 136 of the slider 120.
  • the slider 120 is displaced in translation along the axis 125, until the second lateral wall 136 arrives in abutment against the cover 42.
  • the slider 120 has then reached the initial blocking configuration, such as shown in figure 3.
  • the pawl 56 again crosses the ridge 132 in order to return in the first notch 128, which emits a "click” sound, indicating to the user the return to the blocking configuration.
  • Such a blocking mechanism effectively prevents untimely dispensing of cosmetic product, while still benefiting from the seal provided by the protective cap.
