PURPOSE:To simplify the assembling operation of a blood sampling tube so that said tube can be easily opened or close, while making it possible to reuse a closing member thereof by a method whereby a cap member is fitted in an outer periphery of an opening of said bottomed tubular body with a sealing material interposed therebetween and said closing member is placed on said cap member. CONSTITUTION:When a cap member 5 is fitted in a bottomed tubular body 1, it is screwed into the body while the head thereof is rotated. Accordingly, the cap member 5 can be easily and rigidly secured to the tubular body 1 with a sealing material 4 interposed between the member and an opening end 2a of the tubular body 1. A gas barrier member 7a and a reusable sealing member 7b may be bonded onto the cap member 5 either before or after the cap member 5 is mounted in the tubular body 1. When this tubular body is used to sample a blood, a hollow needle provided with a drawing holder is pierced into the members 7a, 7b, and further into the interior of the tubular body 1 through a needle piercing section 6 of the cap member 5. Accordingly, the blood entering from an end of the needle runs in the hollow part of the needle and flows into the tube. Thus, the blood is sampled in the tube. |
