ABSTRACT:
An applicator for applying liquids to surfaces, especially highly mobile liquids of low viscosity, the applicator comprising a cap-like body (30) in a transverse wall (50) of which is a dispensing aperture (60). An applicator pad (90) is bonded to the outside of the transverse wall and there is a diaphragm (70) on the other side of the transverse wall, covering the dispensing aperture. The diaphragm (70) has a slit (80), radially spaced from the dispensing aperture.
An actuator member (100) extending through the dispensing aperture (60) rests with one end in contact with the diaphragm (70) and its other end in the applicator pad (90) so that pressure on the applicator pad (90) is transmitted via the actuator member (100) to displace the diaphragm (70) from the dispensing aperture (60) and open the slit (80).
The applicator resists accidental discharge of liquid and is particularly useful for applying treatment liquids to the leather of shoe uppers to impart a shine.
