PROBLEM TO BE SOLVED: To provide a container valve capable of being smoothly opened/closed for a long period. SOLUTION: Within a housing (3) of a container valve (2), a fluid entrance (5) is communicated to a fluid exit (7) via a valve seat (9) and a valve chest (10). A closing member (15) is inserted into the valve chest (10). A spindle (17) is inserted into a guide hole (14) communicated with the valve chest (10), the closing member (15) is connected with a handle (18) via the spindle (17) and the closing member (15) is constituted on the valve seat (9) so that an opening/ closing operation may be performed by the handle (18). Between the closing member (15) and a peripheral wall of the valve chest (10), an annular scraper (21) is mounted. An inner peripheral surface of a lip (21a) of the annular scraper (21) is made to abut on an outer peripheral surface of the closing member (15). Between the closing member (15) and the guide hole (14), a sealing tool (23) is mounted.
