A blood collecting tube comprises a bottom-closed tubular member (10) closed at the bottom and open at the other end, a stopper (20) having an upper flange portion (21) and a lower annular skirt portion (22) extending therefrom and being fitted in the open end of the tubular member (10), and a cap member (30) placed on the tubular member. The tubular member (10) has an annular flange (11) so designed that its diameter increases in the direction toward the closed bottom to form a groove between its flange (11) and the flange (21) of the stopper (20), whereas the cap member (30) is provided with at least two inward projections (34,35) of which one projection is adapted to engage with the flange (11) of the tubular member (10), the other projection being engaged with the flange (21) of the stopper (20) and held in the groove. <IMAGE> |
