【考案の詳細な説明】
（産業上の利用分野）
この考案は天蓋の取外しが可能なオープンドラ
ム缶に関する。[Detailed description of the invention] (Field of industrial application) This invention relates to an open drum can with a removable canopy.
（従来の技術）
化学薬品など有害な危険物をドラム缶に密封し
て長期間倉庫などで保管することが行なわれてい
る。(Prior Art) Hazardous substances such as chemicals are sealed in drums and stored in warehouses for long periods of time.
また、保管が長期にわたるためドラム缶が腐食
する虞れがある場合、保管の途中で内容物を新し
いドラム缶に入れ替えることも行なわれている。 Additionally, if there is a risk of corrosion of the drum due to long storage, the contents are replaced with a new drum during storage.
さらに、ドラム缶の地板は長期間の負荷により
下方に張り出すように変形することがある。この
ため、従来では地板の底面に十字形あるいは放射
状に帯鋼を溶接し、地板を補強していた。 Furthermore, the base plate of the drum may deform in such a way that it bulges downward due to long-term loads. For this reason, in the past, steel bands were welded to the bottom of the base plate in a cross shape or radially to reinforce the base plate.
（考案が解決しようとする問題点）
しかし、保管期間が数年ないし数十年と長期間
にわたる場合、その間にドラム缶が外側から腐食
して内容物が漏れ出る虞れがある。(Problem that the invention aims to solve) However, if the drum is stored for a long time, from several years to several decades, there is a risk that the drum will corrode from the outside and the contents will leak out during that period.
また、上記のように内容物を新しいドラム缶に
入れ替える場合、入替え作業は危険であるばかり
でなく、多くの手間がかかる。 Furthermore, when replacing the contents with a new drum as described above, the replacement work is not only dangerous but also time-consuming.
さらに、上記地板への補強材の溶接は隅肉溶接
のため、非常に多くの工数を要していた。 Furthermore, welding the reinforcing material to the base plate requires fillet welding, which requires a very large number of man-hours.
（問題点を解決するための手段）

である。 A reinforcing member having a dish-shaped or annular convex portion is fixed to the bottom surface of the base plate concentrically with the cylindrical body by spot welding so as to project downwardly. The reinforcing member is obtained by molding a metal plate material by press working or the like. The outer diameter of the protrusion is approximately equal to the outer diameter of the drum to be accommodated, and when no load is applied to the base plate, the bottom surface of the protrusion is located above the lower end of the drum chime, and the protrusion when no load is applied to the base plate. The height difference between the bottom surface of the section and the lower end of the drum chime section is smaller than the amount of downward displacement of the bottom surface of the convex section when the drum is accommodated. In the case of a drum of normal size, the outer diameter d of the convex portion is about 60 mm to 30 mm, which is the outer diameter of the drum to be accommodated. Also,
When no load is applied to the main plate, the difference in height between the bottom surface of the convex portion and the lower end of the drum chime portion is approximately 2 to 8 mm.
（作用）
内容物を充填したドラム缶をオープンドラム缶
内に収容し、天蓋をして密封する。したがつて、
収容したドラム缶は外気から遮断される。(Operation) The drum filled with contents is placed in an open drum, covered with a canopy, and sealed. Therefore,
The contained drums are isolated from the outside air.
また、凸部の外径は前記収容されるドラム缶の
外径にほぼ等しく、凸部の底面はドラムチヤイム

缶の荷重によりたわみ、凸部の底面は下がる。こ
の結果、ドラム缶の荷重はオープンドラム缶のド
ラムチヤイム部の下端および補強部材の凸部の底
面により支持される。 Further, the outer diameter of the protrusion is approximately equal to the outer diameter of the drum to be accommodated, and the bottom surface of the protrusion is located above the lower end of the drum chime part, so that the bottom surface of the protrusion and the drum chime when no load is applied to the main plate are The difference in height between the lower end of the convex part and the lower end of the convex part is smaller than the amount of downward displacement of the bottom surface of the convex part when the drum is accommodated. Therefore, when a drum filled with contents is housed in an open drum, the base plate is deflected by the load of the drum, and the bottom surface of the convex portion is lowered. As a result, the load of the drum is supported by the lower end of the drum chime portion of the open drum and the bottom surface of the convex portion of the reinforcing member.

バンド（図示しない）により締め付けられる。 As shown in these drawings, the open drum mainly consists of a body 1, a base plate 3, a canopy 9 and a reinforcing member 1.
It consists of 1. A drum chime portion 5 is formed by wrapping the lower end of the drum 1 and the peripheral edge of the base plate 3. A fillet weld 7 is applied to the entire circumference of the upper corner of the drum chime portion 5 near the body plate for airtightness and reinforcement. The canopy 9 has its peripheral edge removably fitted to the peripheral edge of the top of the body 1,
It is tightened by a band (not shown).

なく、また取り扱い易い。 The reinforcing member 11 has an annular convex portion 12 projecting downward, and is fixed to the bottom surface of the base plate 3 by spot welding at several locations. The outer diameter of the annular convex portion 12 is slightly smaller than the outer diameter of the drum in which it is accommodated. Also, the main plate 3
When no load is applied to the base plate 3, the bottom surface of the annular convex portion 12 is located above the lower end of the drum chime portion 5, and the height between the bottom surface of the annular convex portion 12 and the lower end of the drum chime portion 5 when no load is applied to the base plate 3. The difference a is smaller than the amount of downward displacement of the bottom surface of the annular convex portion 12 when the drum is accommodated. As mentioned above, when no load is applied to the base plate 3, the bottom surface of the annular protrusion 12 is located above the lower end of the drum chime 5, so when handling an empty open drum, the annular protrusion 12 Since it does not collide with other objects, the annular convex portion 12 is not damaged and is easy to handle.

Therefore, the contained drums will not corrode during storage. Furthermore, even if the contents leak from the stored drum, the open drum prevents the contents from leaking to the outside, making it possible to store the contents for a longer period of time.
保管が長期にわたるためドラム缶が腐食する虞

入れ替える必要はない。 If drums are at risk of corrosion due to long-term storage, open drums prevent leaks and there is no need to replace the contents with new drums during storage.

することができる。 When a drum filled with contents is housed in an open drum, the load of the drum is supported by the lower end of the drum chime of the open drum and the bottom surface of the convex portion of the reinforcing member. The convex portion is approximately equal to the outside diameter of the drum, and supports the load as a cylinder. Therefore, even if a relatively thin plate material is used as the drum material, the drum chime portion or the base plate will not be damaged even if used for a long period of time. For example, in the case of the dimensions of the above example, the thickness of the base plate could be reduced from the conventional 2.3 mm to 1.6 mm. The reinforcing member has a dish-like or annular convex shape and can be formed as a single piece, so that the reinforcing member can be processed by pressing or spatula drawing. Furthermore, the reinforcing member can be easily fixed to the bottom surface of the base plate by spot welding at several locations. Therefore, open drum cans can be manufactured at low cost.

ドラム缶。 A container containing a drum filled with contents and having a reinforcing member fixed to the bottom, the reinforcing member having a dish-shaped or annular convex part concentric with the cylindrical body, obtained by molding a metal plate material, The outer diameter of the convex portion is approximately equal to the outer diameter of the drum to be accommodated, and the reinforcing member is spot-welded to the bottom of the ground so as to protrude downward, and when no load is applied to the base plate, the bottom of the convex portion becomes a drum chime. The difference in height between the bottom surface of the convex portion and the bottom end of the drum chime portion when no load is applied to the main plate causes the bottom surface of the convex portion to be displaced downward when a drum is accommodated. An open drum characterized by a displacement smaller than the amount of displacement.
