Abstract
A liquid applicator adapted to prevent an application liquid from leaking or drying with a small biasing force. A tip unit for a liquid applicator of the present invention includes a tubular member and a valve member. The valve member is biased toward a distal end thereof by a biasing member so as to seal a distal opening portion of the tubular member. The distal opening portion includes a first tapered surface and a second tapered surface located at a proximal side of the first tapered surface. The first and the second tapered surfaces are in contact with a tapered area and a ring of the valve member, respectively, so as to seal the distal opening portion.
