The invention relates to a device for preparing and dispensing a solution, comprising: -a bottle containing a substance to be dissolved and closed by a stopper in two parts: a rigid rod and a deformable head, - a tube of solvent, closed by a piston adapted to be driven therein. Mixing is effected by placing the piston against the rigid rod; an axial pressure provokes decanting of the solvent; slots which are revealed during this operation allow the air to escape. A deformable head also serves in known manner as instilling teat. As a variant, the atmosphere in the bottle may be maintained under pressure to enable an aerosol to be prepared. |
