Abstract
An atomizer provided with a manually activated pump forming a stopper, which is mounted by force in the opening of the bottle. The bottle is made entirely from a plastic material, moulded as a single piece, and the opening of this bottle comprises on the inside an annular hooking rib and the plastic material used to make the bottle is harder and more rigid than the material used to make the pump body so that the said rib can encrust in the pump body.
