ことが明らかであろう。- In this preferred embodiment, the lower body 1 is made of a metal material with a high degree of drawing.
The upper body 2 is formed by shallow drawing of a metal material and consists of nine short side walls 8 and an upper part Ii9. The height of the 1iII portion 8 of the lower body 2 is within the range of 2, which is equal to the width of the seam 5, or slightly larger than the width of the seam 5.
Comer. The upper wall 9 of the lower body 2 has an upwardly convex tapered surface, and a spout 10 for filling or taking out the contents is formed in the center thereof. Thus, upper body 2
It will be clear that the line is joined on the lower body in the form of a so-called bottle shoulder and mouth.

本発明の金属製容器は、上述した如く、容器胴部の主体
となる側壁が高度のしごき加工を受けて薄肉化されてい
ること及び容器中に存在する唯一の継目が周状側面継目
であり、しかもこの継目は重ね合せ接合で形成されてい
ることの組合せに特徴を有するものである。As mentioned above, in the metal container of the present invention, the main side wall of the container body is thinned through advanced ironing, and the only seam in the container is a circumferential side seam. Moreover, this joint is characterized by the fact that it is formed by overlapping joining.
即ち、本発明の金属製容器には二重巻締部が存在せず、

工程において、容器胴に加わる軸荷重は５０乃至１００
に９のオーダーであって、二重巻締工程において加わる
軸荷重の約半分以下であり、かくして二重巻締の場合に
比して座屈傾向が顕著に減少することが了解されよう。That is, the metal container of the present invention does not have a double seam part,
The spout is sealed with a cap or stopper, so even if the container is extremely closed inside the door,
This eliminates the buckling tendency in the cracks. For example, in a commercial capping process, the axial load applied to the container body is between 50 and 100.
It will be appreciated that this is on the order of 9, less than half the axial load applied in the double seaming process, thus significantly reducing the buckling tendency compared to double seaming.
しかも、本発明の金属製容器中に存在する周状側面継目
は軸方向に加わる荷重Ｉこ対して強い重ね合せ接合で形
成されているため、本発明の容器は圧カヤ衝撃に対して
著しく強い構造となっている。Moreover, since the circumferential side seam present in the metal container of the present invention is formed by a lap joint that is strong against the load I applied in the axial direction, the container of the present invention is extremely resistant to pressure impact. It has a structure.

目の剪断強度迄耐えることが可能となるのである。In other words, when using other joining methods such as double-sealed seams, lock seams, or butt joints, when the material is thin, the seams are formed by the load applied to the seams. The material deforms in the first four corners, and this deformation causes leakage at the seam and failure of the seam to occur under relatively small loads. On the other hand, in the case of lap joints, even if the material forming the seam is extremely thin, the deformation of such material does not occur (and the shear strength of the joint, which is unrelated to the thickness of the material, can withstand). becomes possible.
