〔利用分野及び発明の概要］
本発明は、エアーゾル容器等の圧力容器、特に、その底
部を胴部に接着固定する形式の容器の製造方法に関する
ものであり、胴部内周面と底板の周壁との接着面積を増

加わった時の構成壁面の変形に対するシール部の損傷を
防止できるようにするものである。[Detailed Description of the Invention] [Field of Application and Summary of the Invention] The present invention relates to a method for manufacturing a pressure container such as an aerosol container, particularly a container whose bottom is adhesively fixed to a body. In addition to increasing the adhesive area between the peripheral surface and the peripheral wall of the bottom plate, even when using a highly viscous adhesive, the adhesive sufficiently penetrates into the adhesive gap to improve the sealing performance of the adhesive part. Moreover, it is possible to prevent damage to the seal portion due to deformation of the constituent wall surface when internal pressure changes or impact loads are applied.
［従来技術及びその問題点］
細口圧力容器はエアーゾル容器等として大量に使用され
ているが、従来は、有底寸胴容器を製作して、この開口
部をネッキング加工によって細口に構成し、この細口部
にバルブ装置を具備させた蓋体を装着するようにしてい
る。[Prior art and its problems] Narrow-mouth pressure vessels are used in large quantities as aerosol containers, etc., but conventionally, a bottomed body container is manufactured, and this opening is formed into a narrow opening by necking. A lid body equipped with a valve device is attached to the part.
ところが、この従来のものでは、例えば、アルミニュー
ム等の、加工性に富む材質を使用するしかなく、必然的
にその耐圧性が低いものとなる。However, in this conventional type, a material with high workability, such as aluminum, must be used, and its pressure resistance is inevitably low.
そこで、更に耐圧性の要求される圧力容器の場合には、
第７図及び第８図に示すように、−旦細口の下端開放の
筒状体（１）を製作し、この下端開放部（１１）に別体
に形成した底板（２）を接着とカシメ止めによって装着
する形式の圧力容器が特開昭４９−１２５９１７に提案
されている。Therefore, in the case of pressure vessels that require even more pressure resistance,
As shown in Figures 7 and 8, a cylindrical body (1) with a narrow opening at the lower end is manufactured, and a separately formed bottom plate (2) is attached to the open lower end part (11) by gluing and caulking. A pressure vessel of the type that is attached with a stopper has been proposed in Japanese Patent Laid-Open No. 49-125917.
この従来のものは、予め、下端開放の細口の筒状体（１
）を製作するものであるから、アルミニューム以外の硬
い材質の金属材料、例えば鋼板等によっても容器の胴部
が製作できる利点がある。This conventional type has a narrow-mouthed cylindrical body (1
), there is an advantage that the body of the container can be made of a hard metal material other than aluminum, such as steel plate.
ところが、この従来のものでは、筒状体（１）の下端開
放部（１１）の近傍に接着剤（３）を塗布し、そのあと
、別体の底板（２）を胴部の下端開放部（１１）に圧入
し、次いで、前記胴部下端を内方に屈曲させて前記接着
部をカシメ止めしていることから、耐圧強度については
、十分となるものの、シール性及びシール部の強度が不
十分である。However, in this conventional device, the adhesive (3) is applied near the open lower end portion (11) of the cylindrical body (1), and then a separate bottom plate (2) is attached to the open lower end portion of the body. (11), and then the lower end of the body is bent inward and the adhesive part is caulked, so although the pressure resistance is sufficient, the sealing performance and the strength of the sealing part are low. Not enough.
これは、下端開放部（１１）の内周面に接着剤（３）を
塗布して底板（２）を圧入した場合、底板（２）の周縁
のスカート部（２１）が圧入されるに伴なって、接着剤
（３）が筒状体（１）の内周面から剃がれるようにして
スカート部（２１）の内方ｔ４縁部に集合し、前記圧入
完了時点では、集合接着剤がその断面の中央部において
凸になった塊状となり、底板（２）の周囲全域にこの塊
状部が連続するからである。This is because when the bottom plate (2) is press-fitted after applying the adhesive (3) to the inner circumferential surface of the lower end open part (11), the skirt part (21) on the periphery of the bottom plate (2) is press-fitted. As a result, the adhesive (3) is shaved from the inner circumferential surface of the cylindrical body (1) and gathers at the inner t4 edge of the skirt portion (21), and at the time of completion of the press-fitting, the adhesive (3) gathers at the inner t4 edge of the skirt (21). This is because it forms a convex block at the center of its cross section, and this block continues throughout the entire circumference of the bottom plate (2).
又、前記接着剤（３）として、接着強度において優れた
硬化型の接着剤が採用されるからである。Further, as the adhesive (3), a curable adhesive having excellent adhesive strength is used.
即ち、前記のように下端開放部（１１）の内周面に塗布
した接着剤（３）が圧入によって剃かれることから、圧
入完了時にはスカート部（２１）の外周面と下端開放部
（１１）の内周面との間には接着剤（３）が殆ど介在し
ないこととなり、主に、上記の塊状部によってシールが
確保される。That is, since the adhesive (3) applied to the inner peripheral surface of the lower end open part (11) is shaved off by press fitting as described above, when the press fitting is completed, the outer peripheral surface of the skirt part (21) and the lower end open part (11) are removed. Almost no adhesive (3) is present between the inner circumferential surface and the seal is mainly ensured by the above-mentioned lumpy portion.
従って、接着剤（３）と接着する底板（２）及び接着剤
（３）の内壁面との接着面積が少く、しかも、筒状体（
１）と底板（２）との嵌合部に接着剤（３）が殆ど介在
しなくなって、シール性が不十分となるのである。Therefore, the adhesion area between the adhesive (3) and the bottom plate (2) to be adhered and the inner wall surface of the adhesive (3) is small, and the cylindrical body (
Almost no adhesive (3) is present at the fitting portion between 1) and the bottom plate (2), resulting in insufficient sealing performance.
又、接着剤（３）が塊状となっていることから、更には

たとき、接着剤（３）と対接壁面との接着が剥離されや
すくなり、この結果、シール部分の耐久性が不十分とな
るのである。In addition, since the adhesive (3) is in the form of a lump, and furthermore, since the adhesive (3) is a hardening adhesive, the flexibility of the adhesive (3) is insufficient, making it difficult to prevent caulking. In this state, when the internal pressure of the cylindrical body (1) changes or an impact load is applied and the end plate part of the bottom plate (2) or the lower end open part (11) deforms, the adhesive (3) and the contacting wall surface The adhesive is likely to peel off, resulting in insufficient durability of the sealed portion.

The skirt portion (21) is fitted with a bottom plate (2) having a
and the lower end open part (11) are adhered to each other with an adhesive (3), and the lower end open part (11) is bent inward and the bottom plate (2) is caulked, and the adhesive (3) is 1. In a method for manufacturing a pressure vessel using an adhesive having a high viscosity at room temperature, the sealing performance of the sealing part by the adhesive (3) is improved, and the sealing performance is improved by deforming the wall surface of the container in this sealing part. In order to prevent deterioration and damage to the sealing part, the adhesive that collects on the inner edge of the skirt part (21) should not form a convex lump in the center of the cross section, and should be The technical problem is to ensure that adhesive is sufficiently present in the fitting portion with the bottom plate (2).

。After the adhesive application process, the lower end open part (1) of the cylindrical body (1) is
In the state in which the bottom plate (2) is fitted from 1), the adhesive (3) will gather at the upper end of the skirt portion (21). In particular, since the adhesive (3) has a high viscosity, a sufficient amount of the adhesive (3) is not present at the fitting part between the skirt part (21) and the cylindrical body (1). There is.

維持される。Next, when the fitting part between the bottom plate (2) and the adhesive (3) is temporarily heated, the viscosity of the adhesive (3) is extremely reduced, and the adhesive that had gathered in the previous step is removed. (3
) enters into the gap of the fitting portion. That is, the gap is filled with the adhesive (3) having a low viscosity. Furthermore, due to this intrusion, the cross section of the adhesive that had gathered at the upper end of the skirt portion (21) when the bottom plate (2) was inserted becomes concave at the center. In other words, the cross section of the adhesive (3) gathering portion becomes thinner, and the end plate portion on the inner peripheral side of the skirt portion (21) of the bottom plate (2) and the body wall surface of the cylindrical body (1) are deformed. When doing so, the cross section of the adhesive (3) gathering portion becomes easily deformed. Since the heating time in this step is very short, the viscosity of the adhesive (3) returns to normal after heating is stopped, and the adhesive (3) is attached to the bottom plate (2) and the cylindrical body (1). The fitting part is maintained filled.

てシール性が向上する。The adhesive (3) enters into the gap between the fitting portion of the cylindrical body (1) and the bottom plate (2). That is, since the gap is filled with the adhesive (3) having a low viscosity, the end plate portion on the inner peripheral side of the skirt portion (21) of the bottom plate (2) and the body of the cylindrical body (1) When the wall surface of the part is deformed, use adhesive (3
) becomes more easily deformed, so damage to the sealing part due to changes in internal pressure or impact loads, and problems such as a decrease in sealing performance can be prevented. Since the number of seals increases, the sealing properties are improved compared to the conventional ones mentioned above.
