<P>PROBLEM TO BE SOLVED: To provide an injection container which has an overpressure relief mechanism excellent in operation reliability and assembly reliability, and to provide a valve assembly of the injection container. <P>SOLUTION: The injection container 100 includes: a through-hole formed in the center part; a discharge port 124 spaced from the through-hole; a mounting cup 120 connected to a housing 110 of the injection container 100; a stem housing 220 comprising a hollow part, a vertical installation part 220a and a horizontal extension part 220b; a valve stem 210; and an overpressure preventive valve part formed so as to prevent an overpressure in a housing space S. The overpressure preventive valve part includes: body parts 260, 270 including a first channel 261 which communicates with the hollow part leading to the housing space S and a second channel 271 which is connected to the discharge port 124 from the first channel 261; and an opening and closing module M which is arranged on the first channel 261 so that the second channel 271 maintains a flow cross-section in the direction parallel to the vertical installation part 220a and which is opened and closed by a pressure of the housing space S. <P>COPYRIGHT: (C)2013,JPO&INPIT |
