る。As shown in FIGS. 1 to 3, in the blood collection tube (1) of the present invention, the outer diameter of the tube body (2) is tapered from the opening (9) to the bottom (10), A plurality of ribs (3) are provided on the outer periphery of the body (2) in parallel with the longitudinal axis direction thereof.
The rib (3) is so arranged that, in a cross section including the rib (3), at least one of straight lines (4) connecting the ribs (3) passes through the axis (5) (see FIG. 4), or It is arranged so that the axis (5) is included in the polygon (6) formed by connecting the adjacent ribs (3) (see FIG. 5).
