<P>PROBLEM TO BE SOLVED: To surely close the inside of a pipe by a closing member even when the outer peripheral surface of the closing member is elastically pressed to a deposit in a pipe. <P>SOLUTION: In this pipe closing tool, the outer peripheral surface 2 along the direction of the circumference of the closing member 1 inserted in the pipe B is elastically pressed to the inner surface 3 side of the pipe extending over the substantially whole periphery to thereby close the inside of the pipe, and liquid state sealing material 4 is discharged between the outer peripheral surface and the inner surface of the pipe. The pipe closing tool is provided with a projecting member caused to bite into inner deposit 20 interposed between the outer peripheral surface and the pipe inner surface as the outer peripheral surface of the closing member is pressed to the pipe inner surface side. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
