<P>PROBLEM TO BE SOLVED: To provide an applicator capable of preventing the intermixture of air from an application body and supplying a stable quantity even if pressed from the rear end. <P>SOLUTION: The applicator is adapted to perform a compression stroke in which a storage body 20 is moved forward by a fixed amount or more within a shaft body 10 by the knock operation of a user; when a front valve element 28 is pushed into the tip part of the storage body against the energizing force of a second spring 32, the volume of a space between the front valve element 28 and a rear valve element 30 is reduced to pressurize an application liquid to thereby open the front valve element 28 so that the application liquid flows into the application body through the inside of an application liquid guide tube 26; and an expansion stroke in which the storage body 20 is moved backward within the shaft body 10 by a knock release operation, and the front valve element 28 is returned toward the front within the tip part of the storage body 20 by the energizing force of the second spring 32 to enlarge the volume of the space so that the rear valve element 30 is opened by the decompression of the application liquid to allow the application liquid to flow into the space. <P>COPYRIGHT: (C)2013,JPO&INPIT |
