This invention relates to a device for dispensing a liquid product stored in a container (2) of variable capacity supplying a pumping chamber. The liquid product is expelled through an opening in a dispensing plate (3), the structure of the dispensing device being among other things simplified by, as a minimum: an elastic deformable sealing element (32) behind or flush with a dispensing surface (S3) of the plate, in its closed position and with a part that is movable relative to the dispensing opening (31) so as to open when the liquid product is expelled; an outwardly convex deformable partition (11) forming the chamber; and means enabling a user to apply pressure in order to compress the deformable partition and reduce the chamber, the deformable partition returning by elasticity to its uncompressed position to bring about aspiration. |
