Problems solved by technology

However, the purpose of this metal barrel is to improve the vibration resistance performance as described above. As mentioned above, the above-mentioned groove-shaped forming part is formed in the entire circumferential direction of the metal barrel, but it does not necessarily improve the internal pressure resistance performance.

no. 1 approach

[0052] Such as Figure 4 As shown, the top cover 110 for metal drums in this embodiment is installed as a cover on the open-type metal drum 100 that can be disassembled with respect to the drum body 120. Fastened with barrel body 120 . Here, the open-ended metal bucket 100 is provided with a liner 116 ( figure 1 ), can be used as an open-ended metal barrel for internal pressure resistance. In the present embodiment, the steel metal barrel with an internal capacity of 200 liters is an example. It goes without saying that the capacity is not limited to 200 litres.

[0053] Additionally, if Figure 5 As shown, similarly to the conventional top cover 7 , a wrinkle-removing portion 111 is formed on the top cover 110 for metal drums. The top cover 110 for a metal bucket is formed by pressing a circular steel plate, and the wrinkle removing portion 111 is used to prevent wrinkles from being generated in the top cover 110 during the above-mentioned press work.

[0054] Such a wr...

no. 2 approach

[0078] In the first embodiment described above, the top cover 110 on which the wrinkle removing portion 111 is formed is taken as an example. On the other hand, there are also Image 6 and Figure 7 A so-called flat-topped top cover 110-1 without the crease removal portion 111 is shown. Like the deformation inducing portion 117 described above, the deformation inducing portion 117-1 that exists between the starting end 117a and the terminal end 117b along the diameter direction 110a of the top cover 110-1 can also be formed on this top cover 110-1, so as to be able to The same effects as in the first embodiment described above are obtained.

[0079] Here, the positions of the start end 117a and the end 117b of the deformation inducing part 117-1 may be the positions of the above-mentioned superordinate concept, or may be the limited positions described in the first embodiment. In addition, in Image 6 and Figure 7 The middle diagram shows the situation where the position...

no. 3 approach

[0081] In addition, the present applicant has improved the conventional fastening ring 10 for metal barrels, and developed Figure 8A and Figure 8B A modified fastening ring 200 is shown. In this improved fastening ring 200, the position where the locking members 221, 222 corresponding to the locking members 2, 3 are attached to the end of the belt-shaped member 210 corresponding to the belt-shaped member 1 has been studied, so that it is possible to prevent Generation of the discontinuity 8 described above. That is, if Figure 8A As shown, for the locking member 221, in order to form the area 214 overlapping with the belt-shaped member 210, the locking member 221 is separated from the one end surface 212a of the belt-shaped member 210 along the circumferential direction of the belt-shaped member 210 and the locking member 221 is fixed. on the strip member 210 . On the other hand, the locking member 222 protrudes from the other end surface 213 a of the belt-shaped member ...

Abstract

The invention provides a top cover for a metal drum. For a top cover 110, when the inner pressure of the metal drum rises, a deformation inducement part 117 for generating the deformation is formed at the desired parts along the perimeter of the top cover. Thus when the inner pressure of the metal drum rises, the stress on the top cover is prevented from concentrating on one part of the top coverand dispersed for many deformation inducement parts. Compared with the prior technology, the inner pressure resistance performance of the metal drum is increased.

Description

technical field [0001] The invention relates to a top cover installed on the barrel body of an open metal barrel and a metal barrel with the top cover installed. Background technique [0002] In an open-type metal drum made of steel in which the top cover is detachable from the barrel body, after the contents are filled into the barrel body, a top cover corresponding to a lid is attached to the barrel body to close it. After closing the lid, if Figure 10 shown, will have Figure 9 The shown belt-shaped part 1 having a U-shaped or V-shaped cross-section and constituting a fastening ring 10 for a metal barrel is installed on the joint part of the barrel body 6 and the top cover 7, and the belt-mounted part 1 is locked by bolts 4 and nuts 5 , thereby fastening the bucket body 6 and the top cover 7. A gasket is usually provided at the above-mentioned joint portion of the top cover 7, and the leakage of the contents is prevented by the above-mentioned fastening, and at the sam...
