PURPOSE: To improve the airtightness of a container for application by providing-sealing parts which airtightly press-bond to each other at the closing final end of a cap, on the external surface of a mouth cylindrical part of a container main body and on the internal surface of the cap. CONSTITUTION: A valve unit 20 and valve seat member 30 are attached to a mouth cylindrical part 11 of a container main body 10. A valve body 25 of the valve unit 20 is energized upward by a spring 24, and a valve seal 26 of the valve body 25 sits on a valve seat 35 of the valve seat member 30, and a leading end protuberance 27 goes through a discharging holes 34 and protrudes upward. An application body 40 to cover the leading end protuberance 27 and discharging hole 34 is attached to the valve member 30, and a cap 60 which is screwed with the mouth cylindrical part 11, annular protuberances 61, 62 are provided. By this method, at the closing final end of the cap 60, the annular protuberance 61 is airtightly press-bonded to a flange part 12 of the container main body 10, and the annular protuberance 62 is fluid-tightly press-bonded to a fixed ring 32. Therefore, oxygen in air does not enter the inside of the container from the outside of the container 1 for application, and a volatile component in the container main body 1 is also prevented from valatilizing. |
