Abstract: Push-button applicator device for dispensing liquids intended to be mounted on a dosing pump or aerosol valve on the mouth of liquid containers, and to provide for the dispensing of liquids in a uniform and controlled way on a surface through the use of a spongy material part, and wherein the inadvertent operation of the dosing pump is prevented during storage. The device includes a fixed part (7) which is mounted on a dosing pump (8) or aerosol valve on the neck of the liquid container (10). The free end of the fixed part surrounds the whole periphery of the discharge tube (17) which emerges from the pump. A movable part (4) is adapted for mounting both to the discharge tube of the pump and to the upper end of the fixed part (7).
