There are two main things to notice in the design of the base of soda cans (Why soda can have beveled edges). The first is the dent in the bottom part. You must have noticed that the bottom parts of soda cans are not flat. They are like a dent in the inside.

Why bottom of soda can concave?

There might be many people who are fond of drinking cold drinks, but the youth prefer drinking cold drinks in aluminum cans more than plastic bottles. The design of a soda can (Why bottom of soda can concave) is quite unique. But its lower part, that is, the base, is always pitted and its corners are raised. By looking at the picture, you must have understood what I am saying. Almost all soda cans have a similar design. Have you ever wondered why it is so?

According to the Reader’s Digest website, there are two main things to notice in the design of the base of soda cans. The first is the dent in the bottom. You must have noticed that the bottom parts of soda cans are not flat. They are bent inwards. Such a base is made so that the soda cans can withstand more pressure. Actually, there is carbon dioxide gas inside, which exerts pressure outwards. Aluminum cans are very thin which can easily get crushed.

The Soda Can Bottom Part is Very Special

But because of this dented design, soda cans can withstand pressure of up to 90 pounds per square inch and do not burst. The second thing worth noticing in the bottom part is the raised corners. The bottom design is such so that they can stand easily on a table or in the fridge and do not fall. They can be easily stacked even in limited spaces. Many videos are also posted on social media, in which it is told that you can also open another can with the raised corners. You just have to pull the tab of the other can in the corner of the can and open it.

The Design Was Not Like This From The Beginning

According to Reader’s Digest, the bottom corner of the soda can was not always raised. Around 1967, companies like Pepsi and Coca Cola switched to aluminum cans. Earlier they used to sell cold drinks in bottles only. Gradually they changed the design of the can and made its corners raised, so that people can open one can from another and can keep the cans properly anywhere.
