When you are drinking drinks, have you noticed that the bottom of many drinks bottles is in the shape of a five-petal flower?
Maybe you will think that this design is to hold less drinks and visually deceive consumers.
In fact, such a design will not save costs, because each bottle of drink has a capacity standard.
Filling must be within the specified standard error.
Some people also think that the five-petal flower-shaped bottom design looks very classy.
Indeed, visual beauty is part of the reason, but this is not the original intention of its design!
This five-petal bottle bottom design is usually used to hold drinks with "qi".
This is because there is gas in carbonated drinks. During transportation, the carbonic acid gas will expand due to shaking.
This will generate a lot of pressure, and the five-petal flower design can disperse the pressure caused by gaseous drinks and avoid bottle explosion.
If there is no pressure resistance, the bottles will be damaged due to collision with each other during transportation.
How does the five-petal flower-shaped bottle bottom resist pressure?
When filling carbonated drinks, carbon dioxide needs to be injected into the bottle.
At this time, the bottle needs to withstand about 4 atmospheres of pressure
PET material does not have the hardness of glass bottles
Therefore, the bottom must be designed with a concave design and a structure of elongated ribs.
Evenly distribute the pressure inside the bottle at the bottom of the bottle
Only then can the bottle be "as stable as a mountain" after filling with aerated beverages.
After repeated experiments by designers
This five-petal flower-shaped bottle bottom is a design method that saves materials and has good pressure resistance.
So now most carbonated drink bottles use this design
Don’t underestimate a bottle containing drinks
There is a lot of knowledge behind it, it must not only be beautiful
It must also meet the requirements of human body, aesthetics and physics.
