Resumen
Manually operated portable duster, comprising a vertical cylinder (2) that houses a powder and inside which there is a piston (4) with free longitudinal movement; a screen (7) arranged at a lower end of the vertical cylinder; and a horizontal cylinder (10) connected to said vertical cylinder at its lower end, comprising a narrowing at one of its ends, in which there is an outlet (11) for pulverized powder. Through the longitudinal movement of the vertical cylinder (2), the movement of the piston (4) is caused within the cylinder, which forces the passage of the powder through the sieve (7) to the horizontal cylinder (10) and through said cylinder to the outlet (11).
