Try looking at various brands of drinks in minimarkets. Even though the contents are different, the shape of the can is almost always the same.
This design is not because all manufacturers copy each other. The cylindrical shape is very efficient at withstanding internal pressure.
Apart from being strong, this shape is also more material efficient than many other shapes with the same capacity.
Cylindrical cans are also easier to arrange during the shipping and storage process, so they can save space in warehouses and vehicles.
So the shape of the can that looks ordinary is actually the result of a combination of engineering knowledge, production efficiency and ease of distribution.
