Everyone found the water bottle has broken lines but the reason for their existence is that some people are good

Open a billion bottles of water, but do you know the existence of rough roads in the water bottle? And this is the answer for you.

Water bottles are one of many things used by many people because of their convenience and cleanliness.

But did you notice that the mouth of the rotating bottle has "rough roads" running around the bottle?

What do they do?

Obviously, everything has its causes and these raised lines will create small empty slots to help close the bottle cap. They will help prevent water from spilling, spilling out - extremely effective when you move.

Besides, these empty slots have one more use. When opening the bottle, the compressed air flow in the bottle will escape through small gaps in the bottle mouth.

This makes the air in the bottle uncompressed with excessive pressure, resulting in the bottle cap being thrown out, which is dangerous to the user.

Therefore, the type of gas water or easy-to-compress milk bottles are contained in bottles with the bottle mouth with a rough, broken path.

And yet, the empty slots also help prevent many kinds of tiny insects that intend to penetrate inside. They will be stopped at the rough roads running around that bottle's mouth.

There, just a few lines up at the mouth of the bottle is simple but hidden behind it is a series of utilities included. That said, nothing in this world happens without its reasons, right?
