Description of the Related Art Conventionally, in all products such as containers, there are various methods for assembling a main body and a member to be assembled with the main body, depending on their use. For example, there is a method in which projections and undercuts are formed and engaged with each other before they are assembled, or both are fitted and welded.
第４図に示す液体化粧料収納容器は、本出願人によっ

のであり、この中にも本体１と部材２との組付け方法の
一つが示されている。The liquid cosmetic container shown in FIG. 4 shows the technique previously filed by the present applicant (Japanese Utility Model Application No. 59-80240), in which the body 1 and the member 2 are assembled. One of the methods is shown.

壁８上に注出されるものとなっている。In the container shown in FIG.
The assembling of the member and the member 2 is particularly important, and the assembling between the two must be strong and excellent in airtightness. That is, in this container, when the member 2 made of an elastic and soft synthetic resin material is pressed, the content liquid in the pressure chamber 12 opens the first check valve 9 through the pipe 11 by the pressure, and the top wall is opened. 8 is poured out. When the pressing on the member 2 stops, the first check valve 9 is closed and the member 2 elastically returns. With the suction force at that time, the second check valve 10 opens, and the liquid in the container is sucked into the pressure chamber 12. Then, when the member 2 is pressed, the pressure closes the second check valve 10, and the liquid in the pressure chamber 12 is discharged onto the top wall 8 through the first check valve 9 as described above. It has become something.
従って、こうした作用を効果的に達成させるために
は、部材２とそれが組付く本体１との組付きが強固であ
り、かつ気密性に優れている必要がある。Therefore, in order to achieve such an operation effectively, the member 2 and the main body 1 to which the member 2 is to be assembled need to be strong and airtight.
この従来技術においては、その点を考慮して、部材２
と本体１との組付き部分にリングパッキン７を嵌着し
て、両者の組付きを強固なものとし、気密性を高めてい
る。In this prior art, considering this point, the member 2
A ring packing 7 is fitted to a part where the body and the body 1 are assembled, so that the two parts are firmly assembled and the airtightness is enhanced.
しかし、これら従来の組付け手段は、特に上記したよ
うな強い組付きと高い気密性とを必要とし、かつ部材が
本体より弾性に富み軟質である場合等においては適当と
は言えず、改善の余地がある。However, these conventional assembling means require a particularly strong assembling and high airtightness as described above, and are not appropriate when the member is more elastic and softer than the main body. There is room.

性変形により弱められて、発揮される挟持力は部材２が
発揮する弾力の範囲内に制限されるため、充分に強くで
きない状態となるからである。That is, the assembling means in the prior art shown in FIG. 4 tightens the assembling portion of the member 2 between the main body 1 and the ring packing 7, and the airtight assembling of the member 2 with respect to the main body 1 by the clamping force due to the tightening. The member 2 is soft and rich in elasticity, so the clamping force acting on the member 2 is weakened by the elastic deformation of the member 2 itself, and the clamping force exerted is exerted. Is limited to the range of the elasticity exhibited by the member 2 and cannot be sufficiently strengthened.
また、部材２に作用させる締め付け力を、部材２が発
揮する弾力よりも強力なものとすると、部材２の本体１
に対する組付き部分が永久変形状態となり、本体１に対
する部材２の強固で気密な組付き状態を維持できなくな
るからである。If the tightening force applied to the member 2 is stronger than the elasticity exerted by the member 2, the main body 1 of the member 2
Is in a permanently deformed state, and the strong and airtight assembly state of the member 2 with respect to the main body 1 cannot be maintained.
本発明は、これらの点に鑑み創案されたもので、本体
と部材との組付きを強固でかつ気密性に優れたものとす
る組付け方法を提供することを目的とする。The present invention was devised in view of these points, and an object of the present invention is to provide an assembling method for assembling a main body and a member in a strong and airtight manner.
上記目的を達成する本発明の手段は、 合成樹脂製の本体に、この本体の成形材料より融点が

も部材の組付き片の表面部分が本体の組付け凹部表面に
溶融密着するまで、部材の組付き片を超音波溶融するこ
と、 にある。Means of the present invention for achieving the above object is a method of assembling a member made of a synthetic resin material having a melting point lower than that of a molding material of the body and being soft and rich in elasticity, to a body made of a synthetic resin. Forming an assembling recess in which a locking projection is provided on the side wall surface; inserting and pressing an assembling piece having a solid structure of the member into the assembling recess of the main body; Ultrasonically melting the assembled piece of the member while pressing against the assembled piece until at least the surface portion of the assembled piece of the member is melt-adhered to the surface of the mounting recess of the main body.
部材の組付き片を本体の組付け凹部に挿入して押圧し
ながら、この部材の組付き片に超音波振動を印加する
と、圧接している部材の組付き片と本体の組付け凹部の
表面部分が発熱し、この熱により融点の低い部材の組付
き片の表面部分が溶融する。When ultrasonic vibration is applied to the assembling piece of this member while inserting and pressing the assembling piece of the member into the assembling recess of the main body, the surface of the assembling piece of the pressed member and the assembling recess of the main body are applied. The portion generates heat, and the heat melts the surface portion of the assembled piece of the member having a low melting point.
この部材の組付き片の表面部分の溶融の進行と、加え

融した表面部分は、本体の組付け凹部表面との間に形成
されている隙間を埋める方向に流動変形し、最終的には
本体の組付け凹部の表面に密着する。Due to the progress of the melting of the surface portion of the assembled piece of the member and the action of the applied pressing force, the molten surface portion of the assembled piece of the member is formed between the assembled concave surface of the main body. Flow deformation in the direction to fill the gap, and finally comes into close contact with the surface of the mounting recess of the main body.
この際、部材の組付き片は無垢構造となっているの

付き片の表面部分を本体の組付け凹部表面に押し付ける
力として作用するので、表面部分を溶融させた組付き片
の組付け凹部に対する密着程度はきわめて高いものとな
る。At this time, since the assembling piece of the member has a solid structure, all of the pressing force applied to this assembling piece acts as a force for pressing the surface portion of the assembling piece against the surface of the assembling recess of the main body. Therefore, the degree of close contact of the assembled piece with the surface portion fused to the assembly concave portion is extremely high.
このため、部材の組付き片に対する押圧しながらの超
音波振動の印加処理を完了して、この組付き片を冷却固

の表面に高い密着程度で弾接させると共に、組付け凹部
の係止突起と強固に係合することになる。For this reason, in a state where the application of the ultrasonic vibration while pressing the assembled piece of the member is completed, and the assembled piece is cooled and solidified, the assembled piece has its surface on the surface of the assembled concave portion. It is elastically contacted with a high degree of adhesion, and firmly engages with the locking projection of the mounting recess.
以下、本発明の実施例を図面を参照しながら説明す
る。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
第１図と第２図は、本発明の一実施例を示すもので、
第４図に示した収納容器において、合成樹脂製の本体１
と部材２との組付けを、本発明方法によって達成したも
のを示すものである。1 and 2 show one embodiment of the present invention.
In the storage container shown in FIG. 4, a main body 1 made of synthetic resin is used.
FIG. 3 shows a state where the assembling of the member 2 is achieved by the method of the present invention.
この第１図および第２図図示実施例においては、本体

に断面三角状の立突起６を周突条状に設け、両側壁面の
上端部付近に、周突条状の係止突起４を相互に対向する
姿勢で設けた構成となっている。In the embodiment shown in FIGS. 1 and 2, the mounting recess 3 of the main body 1 is entirely formed in a circumferential groove shape, and an upright projection 6 having a triangular cross section is provided on the bottom surface in a circumferentially protruding strip shape. In the vicinity of the upper end of the wall surface, circumferentially projecting locking projections 4 are provided so as to face each other.
部材２の組付き片５は、第２図に二点鎖線で図示した

ように、組付け凹部３の容積とほぼ等しい値に設定され
ている。The assembling piece 5 of the member 2 has an inner diameter equal to the diameter of the inner side wall surface of the assembling recess 3 as shown by the two-dot chain line in FIG. Is also formed into a short cylindrical shape having a small outer diameter, and its volume is such that the entire assembly piece 5 is in a state of being fitted into the assembly concave portion 3 in a state where the ultrasonic fusion mounting to the assembly concave portion 3 has been achieved. The volume is set to be substantially equal to the volume of the mounting recess 3.

超音波による組付き片５表面部分の溶融を効率良く達成
するようにしている。The upright projection 6 provided on the bottom surface of the mounting recess 3 is
When the ultrasonic wave is applied while applying a pressing force to the assembling portion, the bite of the upright projection 6 into the assembling piece 5 increases the contact area of the assembling piece 5 with the assembling concave portion 3.
Melting of the surface of the assembly piece 5 by ultrasonic waves is efficiently achieved.
また、係止突起４を、組付け凹部３の両側壁面上端

け凹部３は、その下部の幅よりも開口部の幅の方が小さ
くなり、このため組付け凹部３内全体を埋める状態で位
置している組付き片５は、ほぼ組付け凹部３内に離脱不
能に組付くことになる。Further, since the locking projections 4 are arranged opposite to the upper ends of both side wall surfaces of the mounting concave portion 3, that is, close to the circulating portion, the width of the opening of the mounting concave portion 3 is smaller than the width of the lower portion thereof. Therefore, the assembling piece 5 positioned so as to fill the entirety of the assembling concave portion 3 is assembled into the assembling concave portion 3 almost irremovably.
このように、係止突起４は、組付け凹部３に対する組

力を発揮し、これにより組付き片５の組付け凹部３内へ
の嵌入組付きを強固にかつ安定して維持するものであれ
ば良いのである。As described above, the locking projections 4 function to maintain the fitting of the mounting pieces 5 into the mounting recesses 3 firmly. Therefore, as in the other embodiment shown in FIG. The attachment recess 3 may have a structure in which the width of the attachment recess 3 is increased toward the bottom surface, and the inner and outer opening edges of the attachment recess 3 may be used as the locking projections 4. In short, the locking projection 4 exerts a strong locking force against the movement of the assembling piece 5 fitted in the assembling recess 3 in the detaching direction, and thereby the assembling recess 3 of the assembling piece 5 What is necessary is just to maintain the fitting fitting inside firmly and stably.
なお、組付け凹部３は周溝構造に限定されることはな

脂材料製の部材とを、強固にかつ密に組付ける場合に、
有効に適用することができる。The mounting recess 3 is not limited to the peripheral groove structure, but may be a blind hole structure. The present invention is limited to the combination of the main body 1 and the member 2 in the storage container of the illustrated embodiment. Without, when a synthetic resin body and a member made of a synthetic resin material having a lower melting point than the molding material of the main body, and soft and elastic, are firmly and densely assembled,
Can be applied effectively.
本発明は、上記した構成となっているので、以下に示
