Abstract

Manual sprayer, of the type consisting of a one-piece body comprising means for coupling the sprayer to the mouth of a container, a pumping chamber, an outlet nozzle in communication with the pumping chamber through a calibrated orifice, means for the movable assembly of the actuating lever of a piston displaceable in the pumping chamber, incorporated in a tubular sleeve that extends in a tube that penetrates inside the container, whose sleeve closes or opens an air inlet, according to the position of the plunger, and a spring that tends to place the sleeve and the plunger in the rest position, while inside the nozzle there is a stem with one end forming a shutter facing the calibrated orifice, whose stem is loosely located with respect to the walls of the interior of the nozzle and can adopt a release position in which it leaves free the passage to the fluid pumped by the plunger, through the orifice calibrated, and another in which closes said hole, whose closing position can be stabilized by a device operable from the outside of the nozzle, characterized essentially by the fact that the aforementioned device consists of a cap screwed on the end of the nozzle, equipped of an exit orifice and of an internal extension that penetrates inside the nozzle, whose extension can push the obturator until it is positioned against the calibrated orifice, closing it, or releasing it and leaving the orifice open, according to the angular position of the stopper.
