Abstract: A liquid applicator includes a liquid pressing mechanism 6 for pressurizing an application liquid 4 inside a main body 2 so as to supply the application liquid to an applying member 10 at the front end by the pressing of liquid pressing mechanism 6, wherein the applying member 10 is made of an elastic material, has a valve structure 8 which is formed with a communication path 24 for communication between the inside and outside of main body 2 and can close the communication path 24 by elasticity in the normal condition and open the communication path 24 by elastic deformation of the communication path when the application liquid is pressurized by liquid pressing mechanism 6, and, an ejection opening 24a of communication path 24 of valve structure 8 is arranged to front onto the applying portion 10a of the applying member 10.

Abstract: The present invention provides a liquid applicator which enables easy application of an application liquid even if it is high in viscosity and which can protect the application liquid held therein against the contamination by microbes etc.
