レス成形品で構成された容器に関する。[Detailed description of the invention] (Field of industrial application) The present invention relates to a small metal container for liquids suitable for beer containers (beer kegs) etc. with a capacity of 2 to 3. This invention relates to a container made of a press-molded thin metal plate.

る。(Prior Art) Generally, in this type of container, the bottom wall is formed integrally with the body of the container by drawing. In some containers, almost the entire bottom wall is in the shape of a flat partial sphere that swells downward. In a container having such a bottom wall, a plurality of supporting legs are provided on the bottom wall in order to stabilize the container on a table or the like. The supporting legs are composed of protrusions formed integrally with the bottom wall, and are provided at a plurality of locations near the outer periphery of the bottom wall.

くすると特に顕著になる。(Problem that the invention aims to solve) However, in the conventional structure in which the protrusions for supporting legs are provided at multiple locations on the bottom wall, the entire bottom wall portion around each protrusion for supporting legs has a flat and smoothly continuous curved shape. Therefore, the strength against bending and buckling is low. Therefore, when the container is placed on a table or the like, that is, when the protrusions support the contents of the container and the weight of the container itself, there is a risk that the bottom wall portion near the supporting leg protrusions may buckle. Further, such problems become particularly noticeable when the wall thickness of the container is reduced in order to reduce material costs.

The bottom portion 3 is formed into a flat, generally partially spherical shape and bulges downward, and the cross-sectional curvature radius R of the center portion 5 (the portion of the bottom wall body other than the outer peripheral edge portion 6) is set to a large value. bottom wall 3
The outer peripheral edge part 6 has a cross-sectional curvature radius R' smaller than the radius R, and extends downward from the inner periphery of the shoulder part 2 to form a step S between the shoulder part 2 and the center part 5 of the bottom wall. There is. The container wall thickness t is, for example, 0.2 mm, and the step S is set to a value 1 to 2 times the wall thickness t (0.2 to 0.4 mm). Reference numeral 7 denotes a boundary between the shoulder 2 and the bottom 3 (outer peripheral edge 6), and when the container is viewed from the outside, the boundary 7 is a concave fold extending in a circular shape.

It is fixed to the upper opening edge of the body part 1 by caulking. Also, when performing the press drawing process mentioned above, if you apply an epoxy-based or vinyl-based coating agent to the surface of the workpiece to reduce the coefficient of friction against the mold to 0.05 or less, forming can be performed without using lubricating oil. is possible,
Molding work can be simplified. However, when using the above coating agent, the mold surface must be finished with high precision to reduce the coefficient of friction of the mold against the workpiece material.
It must be set to 0.4 or lower.

を高めて座屈を防止することができる。(Effect of the invention) According to the structure of the invention described above, the shoulder 2 curved with a small radius of curvature r is formed at the lower end of the cylindrical body 1, and the supporting leg protrusion 9 is adjacent to the shoulder 2. is provided. Therefore, the shoulder portion 2 acts as an annular reinforcing portion for the bottom wall portion near the protrusion 9, increasing the strength of the portion near the protrusion 9 against the weight of contents, etc., and preventing buckling. .
又、肩部２の半径方向内側に隣接する底壁外周
縁部６もその他の底壁部分よりも小さい曲率半径
R′で湾曲した断面を有しているので、底壁外周

も、内容物等の重量に対する突起９の近傍の部分
の強度を高めることができる。 Furthermore, the bottom wall outer peripheral edge 6 adjacent to the radially inner side of the shoulder 2 also has a smaller radius of curvature than the other bottom wall portions.
Since it has a cross section curved at R', the bottom wall outer peripheral edge 6 also has high strength against bending and buckling. Since the part of the supporting leg protrusion 9 closer to the trunk 1 is formed on the outer peripheral edge 6, the strength of the part near the protrusion 9 against the weight of contents etc. can be increased in this respect as well. .
更に、上述の肩部２と外周縁部６とは、両者の

できる。 Further, the above-mentioned shoulder portion 2 and outer peripheral edge portion 6 form a crease with a concave outer surface shape at a boundary 7 between the two. Therefore, the boundary 7 also becomes a high-strength reinforcing portion, and buckling around the protrusion 9 can be prevented more reliably.
