a metal can

technical field

The invention belongs to the technical field of metal cans, in particular to a metal can.

Background technique

The advantages of metal cans are obvious. It has very good airtightness and can resist high internal pressure. It is very suitable for loading carbonated beverages that only require a little pressure, air and acid resistance. For fruit and vegetable juices, organic acid is an important component that determines its taste, which can show the unique aroma of fruit. The ratio of sugar to acid content in fruit and vegetable juice is an important factor affecting the taste, but organic acids are also corrosive to a certain extent. In addition, enzymes, vitamin C, pigments and other important components in fruit and vegetable juice have certain requirements for light and temperature. However, the cans are made of tinplate three-piece cans and aluminum two-piece cans, and are also internally coated with epoxy novolac (sometimes a vinyl coating is required on the epoxy novolac internal coating), so that, Those organic acids in fruit and vegetable juices do not pose a threat at all. As we all know, people pour bottled beer into a cup when drinking beer, but in the process, it will cause a lot of foam in the beer, which not only affects the mood of the drinker, but also if you drink beer. Drinking the foam in the stomach can also cause a bloated stomach.

SUMMARY OF THE INVENTION
