Description

Technical Field

[0001] The utility model relates to the technical field of packaging barrels, in particular to a C-shaped packaging barrel with a sealed cover. Background Art

[0002] Storage and transportation steel drums are widely used in industries such as chemical, petroleum, food and medicine for the storage and transportation of liquids and solid substances. Traditional storage and transportation steel drums have some shortcomings in the design and manufacturing process, such as insufficient strength, poor sealing, high production cost and other problems. In the prior art, there are two common methods to enhance the strength of the barrel body: one is to increase the thickness of the barrel body material, and the other is to set reinforcing ribs on the barrel body. However, increasing the thickness of the material will significantly increase the production cost and weight, which is not conducive to handling and transportation; and the existing reinforcing ribs are mostly simple annular or longitudinal ribs, with limited effect. At the same time, the traditional barrel cover sealing method is mostly welding or threaded connection, which is complicated to operate and has poor sealing effect. The top cover of the C-type packaging barrel in the cover is easily deformed by external force, which is not conducive to the support strength. When storing gas with high pressure, the welding point between the top cover and the barrel body is subjected to greater force, and the weld is easy to loosen and crack, which is not conducive to the sealing effect of the packaging barrel and has a short service life. Therefore, those skilled in the art provide a C-type packaging barrel in the cover to solve the problems raised in the above background technology. Utility Model Content
