PROBLEM TO BE SOLVED: To evade danger to injure a fingertip by means of a needle tip even when the needle tip is deviated to the outer side of an opening part by means of missing the mark by pinching a tab by means of fingers of one hand in a state where the fingers are sufficiently separated from the opening part when a used needle is stored in a needle tube protecting cap. SOLUTION: An outer edge part 2a swelled in a little large diameter is arranged in the outer periphery of the opening part in the needle tube protecting cap 1 and a planar tab 3 is arranged in the outer edge part 2a by extension. Hinge parts 3a and 3b are formed at two positions on the board surface of the tab 3 and a tapered boss part 4 with a little small diameter in the tip is arranged on the inner board surface of the tip of the tab 3. Slits 6 are piercingly and circumferentially arranged on the board surface of the tab 3 in the base part peripheral edge of the boss part 4 and a part between the base peripheral edge of the boss part 4 and the planar surface of the tab 3 is connected by a rib 5 at the desired place of the slits 6. When the used needle is stored in the needle tube protecting cap 1, the tab 3 is pinched by the fingers of one hand in a state where the fingers are sufficiently separated from the opening part 2b. |
