如き欠点が生じていた。In this ultrasonic bonding method, the contact surface of a bone that vibrates according to ultrasonic waves is pressed against the sealing area of a double-polymerized synthetic resin sheet to generate heat, thereby welding both synthetic resin sheets together. However, when the synthetic resin sheet bodies are welded together in this way, the horn must be pressed against the synthetic resin sheet bodies, resulting in the following drawbacks.
ずなわら、シール部分から溶レノた樹脂材料がはみ出し

容物性が低下すること等の欠点があった。Further, due to the vibration caused by ultrasonic waves, which is a mechanical impact applied to the synthetic resin sheet, powdered synthetic resin material is scattered from the synthetic resin sheet 1 which is in contact with the horn. There were disadvantages such as the area around the seal becoming dirty due to so-called "powder leakage" and the resistance to contents being reduced due to uneven welding.

定される。On the other hand, the uneven streaks 3 consist of the grooves 3a and the protrusions 3b.
The depression depth of the groove portion 3a from the reference surface 2a and the protrusion height of the protrusion portion 3b from the reference surface 2a are respectively equal, and the synthetic resin sheet, shaped body 4 to be welded is The material of the synthetic resin material being molded, the quality of the synthetic resin sheet body 4, whether the welding is the joining of two synthetic resin sheet bodies 4 as shown in FIG. 8, or the welding as shown in FIG. The value is set according to the purpose of welding, such as forming the bottom of a seal, the flow form of the melted resin material during welding, etc.

０％程度が好適である。According to many experimental results, the depression depth of the groove portion 3a from the reference surface 2a and the protrusion height of the protrusion portion 3b from the reference surface 2a are approximately 1!7 of the height of the sheet-like body 4. 30-5
Approximately 0% is suitable.

に示す如く、接触面２の一方のに平端部に、シート状体
４の溶融した合成樹脂材料の流出を確実に阻止する堰突
片２ｂを突条部すると良い。As described above, the pawn 1 according to the present invention is constructed by molding the uneven stripes 3 on the contact surface 2, and as shown in FIG. It is preferable that the weir protrusion 2b that reliably prevents the outflow of the molten synthetic resin material of the body 4 is provided as a protrusion.
この第５図図示実施例の場合、堰突片２ｂに、シール部
５に成形されるシート状体４の端面を当接させることに
よって、シート状体４に対するホーン１の位置合わゼを
達成し、シート状体４のシールを行うのである。In the case of the embodiment shown in FIG. 5, the end face of the sheet-like body 4 formed in the seal portion 5 is brought into contact with the weir protrusion 2b, thereby achieving alignment of the horn 1 with respect to the sheet-like body 4. , the sheet-like body 4 is sealed.
このように、シール部５の端面が堰突片２ｂに当接して
いるので、溶融した合成樹脂材料は、この１１ｑ突片２
ｂにせき止められてシール部５外に流出することがない
。In this way, since the end surface of the seal portion 5 is in contact with the weir protrusion 2b, the molten synthetic resin material is transferred to this 11q protrusion 2b.
It is dammed up by b and does not flow out of the seal portion 5.
それゆえ、溶融樹脂材料のシール部５外への流出による
シール部５の外観の劣化を生じる恐れが全く無くなる。Therefore, there is no possibility that the appearance of the seal part 5 will deteriorate due to the molten resin material flowing out of the seal part 5.
この第５図図示実施例の場合は、ホーンｌとシールされ

施例の如く、接触面２の両長手端部を基準面２ａと同一
高さレベルとなった平坦面２ｃ、 ２ｃとするのが良い
。In the case of the embodiment shown in FIG. 5, it is necessary to accurately align the horn l and the sheet-like body 4 to be sealed.
If it is difficult to accurately align the horn 1 and the seal I-shaped body 4 to be sealed, as shown in the embodiment shown in FIG. It is preferable that the flat surfaces 2c, 2c be at the same height level as the .
この第６図図示実施例の場合、ホーンｌとシート状体４
との位置合わせが多少狂ったとしても。In the case of the embodiment shown in FIG. 6, the horn l and the sheet-like body 4
Even if the alignment is slightly off.
凹凸スジ３に対向するシート状体４部分の前後のシート
状体４部分に平坦面２Ｃが押圧されて位置するので、前
記凹凸スジ３に対向したシート状体４部分の溶融した樹
脂材料が９前後方向に流出するのを確実に阻止すること
が出来るのである。Since the flat surface 2C is pressed against and positioned on the sheet-like body 4 portions before and after the sheet-like body 4 portion facing the uneven streaks 3, the molten resin material of the sheet-like body 4 portions facing the uneven streaks 3 is It is possible to reliably prevent the fluid from flowing out in the front-rear direction.
第７図図示実施例は、第５図図示実施例におりる堰突片
２ｂを設けなかった接触面２の他方の長手端部を、第６
図図示実施例に示された。平坦面２ｃに成形し、もって
より完全な溶融樹脂材料流出阻止能力を持つようにした
ものである。The embodiment shown in FIG. 7 has a sixth
This is shown in the illustrative embodiment. It is molded to have a flat surface 2c, thereby having a more complete ability to prevent the flow of molten resin material.
このように９本発明によるホーン１ば、その接触面２に
凹凸スジ３を設げているので、成形されるシール部５に
は、このシール部５に沿って凹凸のスジ５ａが成形され
ることになる。As described above, since the horn 1 according to the present invention has the uneven stripes 3 on its contact surface 2, the uneven stripes 5a are formed along the seal portion 5 on the seal portion 5 to be molded. It turns out.
このシール部５に成形される凹凸のスジ５ａのうら、凹
スジ５ａ部分は、突条部３ｂに対応して成形される部分
であるので、大きな押圧力によりほぼ線状に成形される
ことになる。The back of the concave and convex lines 5a formed on the seal portion 5 and the concave lines 5a are the portions formed corresponding to the protrusions 3b, so they are formed into an almost linear shape by a large pressing force. Become.
それゆえ、各凹スジ５ａ部分は、大きな押圧力が集中作
用して成形されるごとになるので、この凹スジ５８部分
におけるシート状体４同志の溶着は。Therefore, each concave stripe 5a is formed by a concentrated pressing force, so that the sheet-like bodies 4 are welded together at the concave stripe 58 portion.
凹スジ５ａ部分全域で完全に達成されることになっ′０
極めて密にかつ強力に溶着される。This is completely achieved in the entire area of the concave streak 5a.
Welded extremely tightly and strongly.
この凹スジ５ａ部分に隣接して成形される凸スジ５７１
部分は、溝条部３ａに対応して成形される部分であるが
、この凸スジ５ａ部分は、殆ど押圧力を受けることなく
成形される部分であるので、この凸スジ５ａ部分にお＆
Ｊるシート状体４同志の強力な溶着は期待出来ないが、
前記した凹スジ５８部分から流動移動してくるシート状
体４の溶融した樹脂材料を位置させることが出来るので
、シール部５外に溶融樹脂材料を流出させて、シール部
５の外観を劣化させずにすむ。A convex line 571 formed adjacent to this concave line 5a portion
This part is a part that is molded corresponding to the grooved part 3a, but since this convex streak 5a part is a part that is molded without receiving almost any pressing force, the convex streak 5a part is molded.
Although we cannot expect strong welding between the Jru sheet-like materials 4,
Since the molten resin material of the sheet-like body 4 flowing from the above-mentioned concave stripe 58 portion can be positioned, the molten resin material flows out of the seal portion 5 and the appearance of the seal portion 5 is not deteriorated. I live without.
また、前記した如く、凹スジ５ａ部分は、極めて強力に
溶着される部分となるのであるが、特に第９図図示実施
例のデユープ容器の底部シール部を成形する場合には、
チューブ容器の軸心方向に対し一〇直交する姿勢で複数
本の凹スジ５ａ部分が多重に位置することになるので、
この底部シール部におりるシール力は極めて強大なもの
とすることが出来る。Further, as mentioned above, the concave stripe 5a is a part that is extremely strongly welded, especially when forming the bottom seal part of the duplex container of the embodiment shown in FIG.
Since the plurality of concave stripes 5a are positioned in multiple positions in an orientation perpendicular to the axial direction of the tube container,
The sealing force exerted on this bottom seal portion can be extremely strong.

ない。Also, since the groove part 3a is located adjacent to the protruding part 3b and each of the concave and convex lines 3 is rounded, the concave line 58 of the seal part 5 can be melted from the concave line 58 part. The fluidly moving resin material of the sheet-like body 4 is quickly and smoothly moved to the convex stripe 5a portion, and the appearance of the seal portion 5 is not deteriorated by the melted synthetic resin material 11.

を確実に成形することが出来るごとになる。Furthermore, since the pressing force for welding seals is concentrated on each protrusion 3b, even when forming a long seal part 5, it is possible to form a 2-strong (dense seal) with a small output. Part 5
This makes it possible to reliably mold the material.
またさらに、成形されるシール部５の形態および成形条

! Since it is possible to reliably prevent the outflow and movement of the resin material, it is possible to mold a seal part with an extremely beautiful appearance.
Furthermore, many I47. It has a very effective effect.
