してある。(Prior Art) Such an ink tube is known from Japanese Utility Model Publication No. 17491/1983. This is done by making the upper end of the suction port tapered upward in diameter, and pushing the cylindrical packing with a flange on the outer periphery of the upper end into the upper end of the suction port from above, and inserting the flange onto the top of the suction port. It has been done.

に洩れることがある。(Problem to be solved by the invention) As mentioned above, the flange of the cylindrical packing is received on the upper end of the suction port and is exposed to the outside, so when it is installed in a rotary copying machine, the inside of the tube is inserted through the suction port. The cylindrical packing may come off the suction port due to rubbing against the tip of the suction nozzle that sucks out the ink, and the ink inside the tube may leak out.

An annular groove for receiving the protruding portion is provided at an interval equal to the above-mentioned interval from the annular packing, and a tapered portion whose diameter decreases downward from the annular groove of the cylindrical packing is set so that the diameter of the lower end of the tapered portion is equal to the diameter of the suction port. It is characterized by being approximately equal to the inner diameter of the protrusion.

ツタリと嵌る。(Function) According to the present invention, the lower end of the tapered portion of the cylindrical packing is inserted into the protruding portion on the inner circumference of the suction port, and the cylindrical packing is pushed into the suction port. As a result, the annular groove on the outer periphery of the cylindrical packing receives the protruding part on the inner periphery of the suction port, and the upper end of the cylindrical packing above the annular groove fits inside the upper end above the protruding part of the suction port. It fits perfectly.
（実施例）
以下、図示の一実施例を説明する。１はプラス
チツク製の薄いチユーブ壁、２は上記チユーブ壁
の上端に嵌着して固定したプラスチツク成形品の

込んで取付ける様になつている。(Example) Hereinafter, one example shown in the drawings will be described. 1 is a thin tube wall made of plastic, 2 is a medium-high head of a plastic molded product that is fitted and fixed to the upper end of the tube wall, and a suction port 3 is integrally provided at the top of the head, and A male thread 3a is provided on the outer periphery, and a cap 4, which is also a molded plastic product, is screwed in and attached.
吸出口３の内周には上端から所定の間隔ｌを保
つて半径方向内向きの張出部５を一体に設けてあ
る。 A radially inward projecting portion 5 is integrally provided on the inner periphery of the suction port 3 at a predetermined distance l from the upper end.
６は合成ゴムなどで成形した弾性質の筒形パツ
キングで、その外径は吸出口３の内径よりも僅か
に大である。筒形パツキングの外周にも上端から
前述の間隔ｌとほゞ同じ間隔を保つて上記張出部
５を受入れる環状溝７が形成してある。そして、
環状溝７の下は下向きに直径が減少したテーパー
部８になつて居り、テーパー部８の下端８′の直
径は前記張出部５の内径にほゞ等しく、好ましく
は僅かに小さい。 Reference numeral 6 denotes an elastic cylindrical packing made of synthetic rubber or the like, and its outer diameter is slightly larger than the inner diameter of the suction port 3. Also formed on the outer periphery of the cylindrical packing is an annular groove 7 for receiving the projecting portion 5 at a distance substantially the same as the above-mentioned distance 1 from the upper end. and,
Below the annular groove 7 is a tapered portion 8 whose diameter decreases downward, and the diameter of the lower end 8' of the tapered portion 8 is approximately equal to the inner diameter of the projection 5, preferably slightly smaller.
従つて、筒形パツキングのテーパー部８の下端

端部６′は吸出口３の張出部５よりも上の上端部
３′内にピツタリと嵌合し、その上面は吸出口３
の上面と同一面になる。 Therefore, when the lower end of the tapered part 8 of the cylindrical packing is aligned with the inner periphery of the overhanging part 5 of the suction port and pushed into the suction port from above, the tapered part 8 deforms radially inward and becomes tensioned. It moves downward through the exit part 5, and when it passes, it tries to restore itself due to its elasticity. In this case, the outer diameter of the cylindrical packing is slightly larger than the inner diameter of the outlet, so the upper end 6' above the annular groove of the cylindrical packing and the upper end of the tapered part 8 are located on the inner periphery of the outlet. The annular groove 7 and the protruding portion 5 of the suction port are pressed together. The upper end part 6' of the cylindrical packing is tightly fitted into the upper end part 3' above the overhanging part 5 of the suction port 3, and the upper surface thereof is connected to the suction port 3.
It will be on the same plane as the top surface of.

ない。(Effects) As described above, according to the present invention, the cylindrical packing does not protrude outward from the upper end of the suction port. The cylindrical packing is strongly held on the inner periphery of the suction port by the engagement between the annular groove and the protrusion of the suction port, and the friction between the outer periphery of the cylindrical packing and the inner periphery of the suction port. When installed, the suction nozzle will not be removed at all.
又、筒形パツキングは環状溝の下にテーパー部
を有し、その下端の直径は張出部の内径にほゞ等
しいので吸出口への挿着も容易に行える。 Further, the cylindrical packing has a tapered part below the annular groove, and the diameter of the lower end thereof is approximately equal to the inner diameter of the overhanging part, so that it can be easily inserted into the suction port.
