  • two bosses 30 are provided at 120 ° on either side of the orifice 24 and in the same radial plane, said bosses having a thickness equivalent to that of the nozzle 29 so as to ensure the centering.
  • This embodiment aims to improve the fixing and sealing of the bellows 4 on the ring 3, in particular when removing the cap 28. It can be used in combination with the embodiment described above to ensure the closure of the dispensing orifice 24 between two uses.
  • the radial clamping of the lower part 5a of the base 5 can be used independently of the realization of the closure, or as a main feature combined with said realization of the closure.
