かる。<Prior Art> Conventionally, a method of sealing a plastic molded product with a stopper, for example, a method of sealing a hole in a plastic container containing a liquid and completely sealing the hole to prevent the contents from leaking, involves applying adhesive or sealing to the stopper. There is a method of applying an agent, plugging the hole, and adhering the orange to the container, or a friction welding method.In other words, the container containing the contents is fixed, the orange is placed in the hole and rotated at high speed, and the orange is attached to the container. There is a method in which rotation is stopped when the outer surface and the part of the container that is in contact with it are rubbed and melted, and the two are welded together. With the former method, there is a concern that the adhesive will deteriorate over time, and 118 has poor adhesive properties.
A durable orange seal cannot be made with fat. The latter method involves welding, which makes it possible to create a durable plug seal, and is preferred, but it requires specialized equipment and is costly.

栓シール方法に関する。Means for Solving Problems> The present invention provides a method for plugging and then sealing a hole in a thermoplastic resin molded product, in which the orange and/or the surrounding area of the hole is convex relative to the reference surface of the molded product. The present invention relates to a method of sealing a plug for a plastic molded product, which comprises providing a concave portion and a concave portion, and then pressing with a heating block to weld the chain hole and the plug.

孔に、該熱溶１性樹脂と同じ材料の、または熱溶−シー
ルが可能な同系統の熱可塑性樹脂製の栓を施こし、つい
で加熱ブロックにて該伶部分および該孔周辺部を加圧し
、熱溶融させシールするものである。More specifically, a stopper made of the same material as the thermoplastic resin, or a thermoplastic resin of the same type that can be heat-melt-sealed, is applied to the hole of a thermoplastic resin molded product, such as a container. Then, a heating block pressurizes the area and the area around the hole to thermally melt and seal it.
そして、本発明の好ましい実施方法における該恰及び該
孔周辺部の構造の例を説・明すれば橙を施こされた状態

場合、すなわち、該容器の孔の周辺部分は該基準面より
も凸に、かつ該栓部の外周部分は凹に、該枠部の中央部
分は凸にするといった方法を採用することもできる。To explain and explain an example of the structure of the structure and the area around the hole in a preferred method of carrying out the present invention, in the state where orange is applied, the area around the hole of the container is more convex than the reference surface of the container. The frame portion is made to be concave relative to the reference plane. Alternatively, conversely, the peripheral portion of the hole in the container is made to be concave relative to the reference surface of the container, and the frame portion is made to be convex relative to the reference surface. Furthermore, in the case of combining these, in other words, a method in which the peripheral part of the hole of the container is made convex relative to the reference plane, the outer peripheral part of the stopper part is concave, and the central part of the frame part is convex. can also be adopted.
−このような構造になるように栓が施こされた状態にて
、該枠部分および該孔周辺部分を所定の温度に加熱され
たブロックで加圧すると、容器または栓の凸部が溶融し
、加圧力によ−り凹部に流れ込み、ここで容器と栓は溶
着一体化する。- With the stopper in such a structure, if the frame and the area around the hole are pressurized with a block heated to a predetermined temperature, the convex part of the container or stopper will melt. , it flows into the recess under the applied pressure, where the container and the stopper are welded together.
ついで、加熱ブロックを該容器Δ）ら離脱し、放冷また
は強制冷却により冷却することによりシールを終了する
。Then, the heating block is removed from the container Δ), and the sealing is completed by cooling the container Δ) by allowing it to cool or by forced cooling.
上記の方法において凹部の容積と凸部の体積が略同−に
なるようにしておけば、シール後の枠部は、容器の基準
面と同一になり平滑とすることができる。In the above method, if the volume of the concave portion and the volume of the convex portion are made to be approximately the same, the frame portion after sealing becomes the same as the reference surface of the container and can be made smooth.
また凹部の容積と凸部の体積が必ずしも同一でなく、凸
部の体積が多いか、または実質的に凹部がなく凸部だ、

込まれ、シール後の容器の表面が平滑になる場合も本発
明の方法に含まれる。Also, the volume of the concave part and the volume of the convex part are not necessarily the same, and the volume of the convex part is large, or there is virtually no concave part and it is a convex part.
The method of the present invention also includes a case in which the convex portion is pushed in by the pressure applied by the heating block and the surface of the container after sealing becomes smooth.
かくして得られる橙のシールでは、容器と栓の樹脂が孔
の周囲全域にわたって溶着されでい、るので、シールは
完全になされ、内容物の漏れ出す恐れはなく、溶着であ
るから、シールの耐久性は、極めてよい。In the orange seal obtained in this way, the resin of the container and the stopper are welded all around the hole, so the seal is complete and there is no risk of the contents leaking out.Since it is welded, the durability of the seal is low. The quality is extremely good.
栓の材質樹脂と容器の材質ＦＩＪ脂に同一または同系の
樹脂を用いることにより溶着強度を大きくすることがで
きる。Welding strength can be increased by using the same or similar resins for the stopper material resin and the container material FIJ resin.
加熱ブロックとしてはヒーターを取付けた金属ブロック
を用い、栓及び容器を加圧する面は、溶融された樹脂が
金属ブロックに付着しない様に、テフロン等をコートし
ておくのがよい。As the heating block, a metal block with a heater attached is used, and the surfaces that pressurize the stopper and container are preferably coated with Teflon or the like to prevent molten resin from adhering to the metal block.
次に図により詳細に説明する。Next, a detailed explanation will be given with reference to the drawings.

In Fig. 1.2, 1 is a container, 11 is a wall surface of a hole to be sealed in the container, 12 is a reference surface of the container, and 18 is a reference surface 12 provided around the container hole.
It is a more convex part.・2 is the stopper, 21 is the outer periphery of the stopper and is concave than the reference surface 12, and 22 is the reference surface 1 of the stopper.
2 shows the part that is more convex. Reference numeral 8 indicates a space formed by the concave portion 21 of the stopper, which is below the reference surface 12. Reference numerals 4 to 4 show cross-sections of the heating block, and although not shown, a heater and a temperature sensor are attached to this block so that the temperature can be maintained at a predetermined temperature. 41 indicates the pressurizing surface of the heating block, which is coated with Teflon resin. The volume of the area 13 along the circumference of the hole with a volume of 6 g and the area 22 of the stopper,
The sum is approximately equal to the volume of the space 8. In Figure 2, the heating block is lowered to melt and pressurize the convex part of the container hole and the convex part of the stopper, so that the surface 41 of the heating block is the reference surface 1 of the container.
It shows the state where it is pressurized to the same height as 2. The resin in the parts 18 and 22 projecting from the reference surface 12 is melted and flows into the space 8, where it is formed into a welded body.Although not shown, if the heating block is raised and the pressurized surface is allowed to cool, The sealed surface is a flat surface with no irregularities, and is the same as the reference surface 12.
