As another related art, Korean Utility Model Publication No. 20-0425952 discloses a packing for sealing underground pipes, which is installed at the end of one side of a pair of underground pipes and is inserted and installed between a pair of connecting pipes whose outer circumferential surface is connected by a connecting joint, includes a circular ring-shaped coupling part which is inserted into and installed on one lateral surface of any one selected from the pair of connecting pipes and whose cross section has an arrow shape; a circular ring-shaped outer sealing part which is positioned at one end of one side of the coupling part and whose cross section has a rectangular shape; a circular ring-shaped inner sealing part which is positioned inside the outer sealing part and whose cross section has a rectangular shape with a width smaller than that of the outer sealing part; and a sealing sill which is positioned inside the inner sealing part and whose cross section has a reversed “V”.
Conventional packing members come in different shapes so as to prevent fluid from leaking out of a pipe. However, once a pipe leaks, the amount of leaked fluid increases over time. Accordingly, the packing can no longer work correctly.
As a means to solve the above-described problems, provided is a packing member for sealing a pipe which includes a fluid accommodating unit that accommodates fluid leaking out of a pipe, so as to seal the pipe more efficiently when the fluid leaks out of the pipe in an early stage.
A packing member for sealing a pipe, which is configured to have a hollow shape inserted into a hollow housing and is configured to accommodate a pipe in the inner hollow hole thereof so as to block fluid flowing in the pipe from leaking out, includes a curved part configured to protrude from both ends of a hollow body towards the inner center of the body, a fluid accommodating unit formed between the curved part and the inner surface of the body and configured to accommodate fluid, and a first flow channel hole formed at an end portion of the curved part and connected to the fluid accommodating unit so as to introduce fluid into the fluid accommodating unit even when the end portion of the curved part contacts the inner surface of the body by means of the pipe inserted into the body.
As described above, a packaging member for sealing a pipe of the present invention has a fluid accommodating unit for accommodating fluid that leaks in an early stage, so as to completely prevent fluid leakage. Additionally, when the fluid that leaks in an early stage is accommodated in the fluid accommodating unit, fluid pressure increases and the pipe is sealed more efficiently thereby preventing fluid leakage. Further, a packaging member for sealing a pipe of the present invention has a significant advantage of sealing the pipe more efficiently by means of the accommodating units provided on both ends of a packing.
A packing member for sealing a pipe 100, which is configured to have a hollow shape inserted into a hollow housing 300 and is configured to accommodate a pipe 200 in the inner hollow hole thereof so as to block fluid flowing in the pipe 200 from leaking out, includes a curved part 120 configured to protrude from both ends of a hollow body 110 towards the inner center of the body 110, a fluid accommodating unit 140 formed between the curved part 120 and the inner surface of the body 110 and configured to accommodate fluid, and a first flow channel hole 121 formed at an end portion of the curved part 120 and connected to the fluid accommodating unit 140 so as to introduce fluid into the fluid accommodating unit 140 even when the end portion of the curved part 120 contacts the inner surface of the body by means of the pipe 200 inserted into the body 110.
If fluid flowing inside the pipe 200 leaks and then is introduced into the fluid accommodating unit 140 through the first flow channel hole 121, the curved part 120 firmly comes into close contact with the outer surface of the pipe 200 by means of fluid pressure inside the fluid accommodating unit 140 such that the pipe 200 is sealed.
Additionally, the first flow channel hole 121 of the curved part 120 is configured to have a half circle shape, a protruding sill 130 is formed on the inner surface of the body 110 the curved part 120 contacts and protrudes inwards, a second flow channel hole 131 is configured to have a half circle shape so as to correspond to the first flow channel hole 121 of the curved part 120 and is formed at the protruding sill 130 such that the first flow channel hole 121 and the second flow channel hole 131 form a circle shape when the end portion of the curved part 120 contacts the protruding sill 130 by means of the pipe 200 inserted into the body.
Further, a plurality of the first flow channel holes 121 and the second flow channel holes 131 are spaced apart at a regular interval along the circumferential direction of the curved part 120 and protruding sill 130.
Further, a step 122 is formed on the outer surface where the curved part 120 contacts the pipe 200.
Below, a packing member for sealing a pipe of the present invention will be described in detail with reference to the attached drawings.

Specifically, a packing member 100 of the present invention includes a curved part 120 configured to protrude from both ends of a hollow body 110 towards the inner center of the body 110, and a fluid accommodating unit 140 formed between the curved part 120 and the inner surface of the body 110 and configured to accommodate fluid.
That is, one end of the curved part 120 is integrally formed at an end portion of the body 110 while the other end is curved towards the center of the body 110, and a space is formed between the curved part 120 and the inner surface of the body 110 so as to accommodate fluid leaking out of the pipe 200. The space is referred to as a fluid accommodating unit 140.
In this case, a first flow channel hole 121 is formed at an end portion of the curved part 120 and connected to the fluid accommodating unit 140 so as to introduce fluid into the fluid accommodating unit 140 even when the end portion of the curved part 120 contacts the inner surface of the body by means of the pipe 200 inserted into the body 110.
Meanwhile, the first flow channel hole 121 of the curved part 120 is configured to have a half circle shape, a protruding sill 130 is formed on the inner surface of the body 110 the curved part 120 contacts and protrudes inwards, a second flow channel hole 131 is configured to have a half circle shape so as to correspond to the first flow channel hole 121 of the curved part 120 and is formed at the protruding sill 130.
Accordingly, the first flow channel hole 121 and the second flow channel hole 131 form a circle shape when the end portion of the curved part 120 contacts the protruding sill 130 by means of the pipe 200 inserted into the body.
Additionally, a plurality of the first flow channel holes 121 and the second flow channel holes 131 are spaced apart at a regular interval along the circumferential direction of the curved part 120 and protruding sill 130 so as to easily introduce fluid into the fluid accommodating unit 140.
Further, a plurality of steps 122 are formed on the outer surface where the curved part 120 contacts the pipe 200, and are configured to incline towards the inner circumferential center of the packing member 100 such that the curved part 120 is blocked from folding outwards when the pipe 200 is inserted.
A packing member 100 of the present invention is preferably manufactured from a synthetic rubber or a synthetic resin.
