The invention relates to a device for preparing and dispensing a solution. A bottle containing a substance to be disolved is closed by a disc-shaped base having a rigid rod thereon and a deformable head. A tube of solvent is closed by an apertured slidable piston. Mixing is effected by placing the piston against the rigid rod and applying axial pressure which dispenses the solvent from the tube, through a capillary channel in the rod and into the bottle. Slots in the rod are revealed during this operation to allow the air to escape from the bottle. The deformable head also serves to pressurize the bottle to permit dispensing therefrom. |
