The dispenser comprises a container (1) and a dispensing head (2) comprising a dispensing channel (5). The channel discharges through a dispensing orifice (6) closed by a resiliently deformable valve (7). The valve includes a portion of complementary shape and size to that of the orifice. This portion is housed in the dispensing orifice and fixed to the dispensing head by its center. Its peripheral edge is supported in a sealed manner against the orifice edge and is free to separate resiliently from the edge under the effect of the dispensed product pressure.
