However, due to problems such as processing errors, it is often difficult to align the threads of the barrel cover and the barrel body when rotating this sealed barrel. Jams often occur during the tightening process, which can easily lead to problems such as poor sealing or spillage of grains. There are also sealed barrels whose barrel covers are connected to the barrel body by buckles, but this structure often requires multiple buckles, which is inconvenient to operate. The production of buckles will increase the difficulty of processing sealed barrels, and as the number of uses increases, the buckles will be at risk of breaking, greatly shortening the service life of the sealed barrel and causing a waste of resources.
