Abstract

Improved dosing device and solution dispenser, characterized in that it essentially comprises the assembly constituted by a first cylinder-like part, which is arranged to be coupled to a general container containing the solution to be dosed so that said solution can penetrate inside it; a second piece that acts as a piston that moves inside at least part of the first piece and is driven by a third external push piece which carries inside a fourth piece consisting of a pass valve elastically mounted which is arranged to normally close the outermost end of a longitudinal perforation existing in the second piece and through which the solution to be dosed is introduced as the pressing action of the plunger on it passes through said perforation overcoming for this the sealing action exerted by the indicated valve, all this assisted by elastic recovery means, stop means, sealing gaskets and auxiliary elements and elements that allow and contribute to the integrated operation of the four main parts indicated for the achievement of that, with each advance movement of the external thrust piece that joins the embolus or, the latter drives a predetermined amount of solution through its longitudinal perforation, open the valve and the dosed solution can access to the outside by means of passages or openings existing in the aforementioned thrust piece.
