PROBLEM TO BE SOLVED: To solve two problems that when a resin-made test tube to be used for urine examination or the like is uncorked, since corked firmly, an examinee feels a pain in his his/her hand when several test tubes are uncorked even when he/she draws on his/her inspection gloves and his/her hand skin peels off when many test tubes are uncorked; and since his/her finger gets torn just after the uncorking work is completed to a certain extent, he/she must touch a unrine-stuck cork with his/her bare hands. SOLUTION: The polygonal or cylindrical tip 7 (shown in figure 4), whose outside diameter is slightly smaller than the inside diameter of a hollow of the upper end of the cork of the test tube, of a polygonal rod or cylinder is inserted into the hollow of the cork 2 (shown in figure 4). The cork can be removed easily from the test tube by levering up a main body 5 of the rod or cylinder by applying the principle of leverage and using around the hollow of the cork as a fulcrum. When the tip is hardly inserted into the hollow, the cork-stuck tip is pushed into the test tube by pushing a central bar 4 (shown in figure 4) from the side of the rear end thereof, and the cork can be dropped in the test tube without touching the cork with his/her hands.
