The metal can consists of a larger diameter bottle, a bottle neck with a gradually decreasing diameter and a bottle neck connected to the uppermost bottleneck (which extends upwards and is threaded and can be screwed on the bottle cap). The outer surface of the bottle is covered with a certain thickness of coating and ink layer, and there is a coating on the outer surface. Wherein the ink layer covers the part except the screw thread of the bottle mouth, and the film thickness difference of the cover coating along the peripheral direction of the thread part of the bottle mouth is ≤8 m, and the thickness of the bottle body part is ≥4 m. When detecting the tank with light, it can be prevented from mistakenly recognizing a good tank as a difference tank.
