Japanese Patent JP7186089
Kind Code:
B2
Abstract:
To provide a pipe closing member which can be applied for sealing pipes having a wide range of different outer diameters and can secure sealing property.SOLUTION: A pipe closing member 1 includes a planar base part 2 having a first through-hole 2a of such a diameter that a pipe can be inserted thereto and a planar seal part 3 which is laminated and manufactured on the base part 2 and is manufactured with material softer than the base part 2. On an area of the inner side of the first through-hole 2a on the seal part 3, a second through-hole 3a having such a diameter as to be smaller than a diameter of the first through-hole 2a and that a pipe can be inserted is formed. On either one side of a part 5 overlapped with each other, a flat surface 3b is formed. The base 2 part and the seal part 3 are closely attached to each other on the flat surface 3b. An area of such a part 5 that the base 2 part and the seal part 3 are overlapped with each other is set so as to be 75% or more and less than 100% of an area of the seal part 3 including the second through-hole 3a.SELECTED DRAWING: Figure 4
