Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、ペール罐の改良に関する。[Detailed explanation of the idea] (Industrial application field) The present invention relates to an improvement of a pail can.
（従来技術）

である。(Prior Art) As shown in FIGS. 1 and 2, the conventional pail can 1 has a main plate 3 that is fitted into the lower opening of a thin cylindrical body 2 and tightened. Either the top plate 5 is removably fitted through a gasket 6 (open type), or the top plate 5 is fitted and tightened like the base plate 3 (closed type).

This is the grip of a.
ところで、上記のような従来のペール罐１の胴
体２は、薄肉（例えば0.34mm厚）の鋼板で形成さ
れているというものの、より安価に、かつ軽量化
するためには、より薄肉の鋼板で形成する必要が
ある。 By the way, although the body 2 of the conventional pail can 1 as described above is made of a thin steel plate (for example, 0.34 mm thick), in order to make it cheaper and lighter, it could be made of a thinner steel plate. need to be formed.
しかしながら、胴体２は円筒状であるために、
厚みを0.34mmよりも薄く（例えば0.3mm厚）する
と、直径方向及び軸方向の衝撃荷重に対する強度
が著しく低下する。この傾向は、鋼板厚みを薄く
するほど顕著に現われる。 However, since the body 2 is cylindrical,
When the thickness is made thinner than 0.34 mm (for example, 0.3 mm thick), the strength against diametrical and axial impact loads is significantly reduced. This tendency becomes more pronounced as the thickness of the steel sheet becomes thinner.
なお、特開昭58−90039号公報では、蓋と底で
密閉できる胴体を有する板金製包装容器におい
て、少なくとも円形の蓋と円形の底を接合するよ
うに形成した胴体の端部を円形状横断面にし、胴
体の中間部を四角形横断面にした板金製包装容器
が提案されている。 In addition, in JP-A-58-90039, in a sheet metal packaging container having a body that can be sealed with a lid and a bottom, the end of the body formed to join at least the circular lid and the circular bottom is circularly transverse. A sheet metal packaging container has been proposed in which the body has a rectangular cross section and the middle part of the body has a rectangular cross section.
しかしながら、中間部が正方形（４角形）横断
面であるうえ、正方形の辺長が少なくとも円形状
胴体端部の外径に等しく設定されているので、ペ
ール缶において中間部を正方形（４角形）横断面
とすることは、加工が困難である。 However, since the middle part has a square (quadrilateral) cross section and the side length of the square is set at least equal to the outer diameter of the circular body end, the middle part has a square (quadrilateral) cross section in a pail can. It is difficult to process it into a flat surface.
また、ペール缶において、正方形の各辺長を
上、下部の外径に等しく設定することも加工が困

方形の各頂部を上、下部の外径に等しく設定する
ことも加工が困難であるうえ、容量も大幅に減少
する。 Furthermore, in a pail can, setting each side length of the square to be equal to the outer diameter of the upper and lower parts is difficult to process, and the outer diameter size is out of specification. Moreover, the strength of each vertical wall portion and each corner portion of the square is weakened, making it impossible to use thin steel plates. Conversely, setting the tops of the squares to be equal to the outer diameters of the top and bottom would also be difficult to process and would also significantly reduce the capacity.
（考案の目的）
本考案は、ペール罐の胴体を、強度を低下させ
ることなく薄肉化することを目的とするものであ
る。(Purpose of the invention) The object of the invention is to make the body of a pail can thinner without reducing its strength.
（考案の構成）
このため、本考案は、上部、中間部、下部が略
同外径のペール罐の胴体の上部と下部は天板と地
板で夫々補強されるから従来通りの円筒状に形成
する一方、該胴体の中間部を８〜20角の正多角筒
状に形成し、かつ該中間部の相隣り合う外面の会
合する各角部に丸みをつけて構成したものであ
る。(Structure of the invention) Therefore, in the present invention, the upper, middle, and lower parts of the body of the pail can have approximately the same outer diameter, and the upper and lower parts are reinforced by the top plate and the base plate, respectively, so that the body is formed into a conventional cylindrical shape. On the other hand, the intermediate portion of the body is formed into a regular polygonal tube shape with 8 to 20 sides, and each corner where adjacent outer surfaces of the intermediate portion meet is rounded.
このように、強度的に弱くなる胴体の中間部を
正多角形状に形成して補強し、かつ丸みにより各
角部への応力集中を防ぐことにより、鋼板厚みが
薄く（例えば0.3mm厚）ても、従来のペール罐と
同程度の必要充分な強度が維持できるのである。 In this way, the middle part of the fuselage, which is weak in terms of strength, is formed into a regular polygonal shape to reinforce it, and the roundness prevents stress concentration at each corner, making the steel plate thinner (for example, 0.3 mm thick). However, it is possible to maintain the necessary and sufficient strength equivalent to that of conventional pail cans.
（考案の効果）
本考案によれば、上部、中間部、下部が略同外

ので、より安価でかつ軽量となり、外径寸法も規
格内に維持可能なペール罐を製造できるようにな
る。(Effects of the invention) According to the invention, since the middle part of the body of the pail can is formed into a regular polygonal shape with the upper, middle, and lower parts having approximately the same outer diameter, it is easy to process, and it is possible to use a steel plate. Since the necessary and sufficient strength can be guaranteed even if the thickness is reduced, it becomes possible to manufacture a pail can that is cheaper and lighter, and whose outer diameter can be maintained within the standard.
（実施例）
第１図及び第２図の従来技術と同一構成、作用
の箇所は同一番号を付して説明は省略する。(Example) Portions having the same structure and function as those of the prior art shown in FIGS. 1 and 2 are given the same numbers, and explanations thereof will be omitted.
第３図及び第４図に示すように、ペール罐１１
の胴体１２は、上部１３、中間部１５、下部１４
を略同一外径として、厚みが薄い（例えば0.3mm
厚）鋼板で形成する。 As shown in Figures 3 and 4, the pail can 11
The body 12 has an upper part 13, a middle part 15, and a lower part 14.
with approximately the same outer diameter and a thinner thickness (for example, 0.3 mm)
Thickness) Made of steel plate.
胴体１２の上部１３はストレートな円筒状に形
成し、下部１４は下窄み（テーパ）の円筒状に形
成する。この上部１３と下部１４の構造は従来と
同様である。 The upper part 13 of the body 12 is formed into a straight cylindrical shape, and the lower part 14 is formed into a tapered cylindrical shape. The structure of the upper part 13 and lower part 14 is the same as the conventional one.
一方、胴体１２の中間部１５は僅かに下窄み
（テーパ）の正多角形状、例えば正18角形状に形
成する。 On the other hand, the intermediate portion 15 of the body 12 is formed into a regular polygonal shape, such as a regular 18-sided polygonal shape, with a slight downward taper.
正多角形状としては、８〜20角形状が好まし
い。７角形状以下であれば、加工が困難になり、
容量も減少する。逆に21角形状以上であれば、円
筒状に近ずくので強度の向上が望めない。 The regular polygon is preferably 8 to 20 polygons. If it is less than a heptagonal shape, it will be difficult to process.
Capacity also decreases. On the other hand, if the shape is 21 sides or more, it approaches a cylindrical shape, so no improvement in strength can be expected.
正多角形状としたのは、中間部１５に局部的な
応力集中が起こつて強度が低下するのを防ぐため
である。 The reason why the shape is a regular polygon is to prevent local stress concentration from occurring in the intermediate portion 15 and a decrease in strength.
また、第５図に詳細に示すように、中間部１５
の相隣り合う外面の会合する各角部１６，……，
１６に僅かな丸みをつける。丸みをつけるのは、
角部１６に応力集中が起こつて強度が低下するの
を防ぐためである。 Further, as shown in detail in FIG.
Each corner 16 where adjacent outer surfaces meet,...
Add a slight roundness to 16. To make it round,
This is to prevent stress concentration from occurring at the corner portion 16 and a decrease in strength.
上記のように多角ペール罐１１を構成すれば、
強度的に弱くなる胴体１２の中間部１５が正多角
形状であるために、直径方向及び軸方向の強度が
従来のペール罐１と同程度まで向上するようにな
り、従つて、胴体１２を薄い鋼板で製造すること
が可能になるのである。 If the polygonal pail 11 is configured as described above,
Since the middle part 15 of the body 12, which is weak in strength, has a regular polygonal shape, the strength in the diametrical and axial directions is improved to the same level as the conventional pail can 1. Therefore, the body 12 can be made thinner. This makes it possible to manufacture it with steel plates.
