a metal can

Abstract

The invention belongs to the technical field of metal tanks, and particularly relates to a metal tank which comprises a cup tank, a top cover, a drainage pipe, an annular ring and a flow scattering bulge. The cup tank is made of stainless steel metal and is in a cylinder shape; the top cover is fixedly arranged at the upper end of the cup tank; a circular truncated cone-shaped cavity is arranged in a flow guiding buckle; the drainage pipe is arranged at the lower end of the flow guiding buckle; the upper end of the drainage pipe is fixedly connected into the middle wall of the top cover; the drainage pipe directly faces the inner cavity of the flow guiding buckle; the lower end of the drainage pipe is inserted to the upper end of the annular ring; the lower end of the annular ring is fixedly arranged on the lower surface of the inner part of the cup tank; dispersing holes are uniformly formed in the lower end of the annular ring; the flow scattering bulge is arranged on the inner sideof the annular ring; a cross section of the flow scattering bulge is in a triangular shape; and the flow scattering bulge is fixedly arranged on the lower surface of the inner part of the cup tank. The metal tank provided by the invention is mainly used for solving the problems that the metal cup tank in the prior art cannot solve the problem that a large number of foams is produced when beer is poured, the mood of people for drinking is influenced, and meanwhile, the stomach is swelled up.

Description

technical field [0001] The invention belongs to the technical field of metal cans, in particular to a metal can. Background technique [0002] The advantages of metal cans are obvious. Its airtightness is very good and it can resist high internal pressure. It is very suitable for carbonated drinks, which only have a little requirement for pressure, air and acid resistance. For fruit and vegetable juice, organic acid is an important component that determines its taste, and it can display the unique aroma of fruit. The sugar-acid content ratio in fruit and vegetable juice is an important reason that affects the taste, but organic acids are also corrosive. In addition, important components such as enzymes, vitamin C, and pigments in fruit and vegetable juices have certain requirements for light and temperature. However, the cans use tinplate three-piece cans and aluminum two-piece cans, and are also coated with epoxy phenolic type coatings (sometimes need to apply a layer of ...
