[Solution] An opening/closing plate of the present drug-accommodating container (V-shaped container) is shaped such that, when blocked, the horizontal distance from the opening/closing plate to a side wall is continuously or stepwise asymptotic downwards from a line connecting the upper and lower edges of the opening/closing plate. The present drug leveling tool is equipped with: a hand-held grip section and a straight rod-shaped member that is for scraping a drug so as to be level, and that is integrally mounted to the distal tip of the grip section and inclined at an acute angle to the main axis of the grip section.
