I don't know if anyone has noticed that the bottom of the soda cans and beer cans we often drink is not flat, but protrudes in. Why?

Is it to look good?

In fact, the bottom of the can does not attract much attention in any shape, so it must not be for the reason of beauty.

Is it to save money by packing less content?

NO ~ NO ~ NO! No matter what kind of drinks, there are default specifications in the industry, and the outer package is marked with a clear capacity value. When filling drinks, businesses should strictly follow the standards set by the state to ensure that the labeled capacity is within a certain error range. The amount of weight that can be carried by that little bit of receding in the bottom of the can won't save the brand much in content costs.

So, there must be a special reason for this design~

Bingo!

The most important reason is that most of the specially designed drinks are carbonated drinks and beer.

Carbonated drinks and beer are infused with carbon dioxide gas. If the bottom of the can is flat, when it is filled with drink, gassed, and sealed, the bottom will pop up like a balloon. As a result, the bottom of the can is designed to be an indented dish that acts like an arched dam against the pressure of the liquid inside.

The cylindrical two-piece can with this design is formed as a whole by stretching the metal sheet, and the tank bottom and the tank body are connected into one, so the tightness is better and the ability of explosion-proof is of course more excellent~

Another reason is that the concave bottom of the can also facilitates the transportation and packaging of finished products.

So, not only is the metal can with the insinuated saucer-shaped bottom design not a visual trick to deceive consumers and save costs, on the contrary, this design will increase the cost of the outer packaging, because the insinuated saucer-shaped design is actually more "waste" than the pure flat bottom, think about it?

Well, that's all about a secret at the bottom. Don't underestimate any of the metal cans we drink every day

According to its 2021 annual report, ORG has an annual capacity of 13.5 billion two-piece cans. Whether it is the quality and stability of their products, or the speed of delivery and responsiveness, the industry leader ORG is excellent.
