- said upper axial wall comprises an internal profile, in particular of curved shape, adapted to guide the fluid leaving said dispensing orifice towards the sides to prevent it from returning directly to said dispensing orifice.
- said entrapment space extends laterally around an upper part of said internal sleeve, which allows the trapped fluid to flow and remain trapped in a lower part of said entrapment space.
- said side wall of said priming cover is at least partially transparent or translucent to allow the fluid contained in said trapping space to be seen after the priming actuations.
- said side wall comprises an external marker, such as a rib, forming a priming indicator.
- said priming cover comprises a side wall of which an upper axial end is open, said trapping means comprising a hollow cap fixed to said upper axial end of said side wall.
- said hollow cap contains an insert, a trapping space being defined between said insert and the bottom of said hollow cap.
- said insert is porous, and can absorb the fluid dispensed during priming actuations.
- an axial passage is provided in said insert to facilitate the transfer of fluid to said trapping space.
- said hollow cap contains a one-way valve comprising a membrane provided with a slit which opens when fluid is dispensed through said dispensing orifice during priming actuations, a trapping space being defined between said one-way valve and the bottom of said hollow cap.
- the present invention also relates to a dispensing head of a fluid product dispensing device, comprising a priming cover as described above.
- the present invention also relates to a fluid product dispensing device, comprising a fluid product reservoir, a dispensing member, such as a pump mounted on said reservoir or a piston sliding in said reservoir, and a dispensing head provided with a dispensing orifice, comprising a priming cap as described above.
- a fluid product dispensing device comprising a fluid product reservoir, a dispensing member, such as a pump mounted on said reservoir or a piston sliding in said reservoir, and a dispensing head provided with a dispensing orifice, comprising a priming cap as described above.
