<P>PROBLEM TO BE SOLVED: To provide a cap with a thread which has the snap-off and snap-on function while maintaining a thred-fixing function similar to that of a conventional cap with a thread, and is attachable/detachable in one operation to/from a male thread part of a container or the like materialized by a test tube body or the like. <P>SOLUTION: The cap 20 with the thread is equipped with a peripheral wall 21 and a pressing unit 25. The peripheral wall 21 has a cylindrical shape having a female thread 23 with the inside diameter and the thread pitch corresponding to those of a male thread 11 of the test tube 10 on its inner peripheral surface. The pressing unit 25 has a projection integrally formed at the predetermined angular position in the circumferential direction of the peripheral wall 21. A plurality of slits 21a and 21b extending in the axial direction from a lower end edge to an upper end edge of the peripheral wall 21 are formed at the angular positions with the predetermined angle in both directions of the circumferential direction of the peripheral wall 21 from the pressing unit 25. <P>COPYRIGHT: (C)2009,JPO&INPIT |
