Why is the bottom of the water bottle designed with a 5-petal flower?

Many people think that this design is simply to increase the aesthetics of the packaging drinks, attract the user’s attention; Others have suggested that this design is to save material costs, to help manufacturers cut down on the amount of water in the bottle.

At the bottom of plastic bottles, manufacturers often write clearly the capacity value because they must strictly comply with regulatory standards. Therefore, the 5-way flower design at the bottom of the plastic bottle is not a random design, but there is a reason for all.

1. Increased hardness

Most plastic bottles use PET material. However, this material has low stiffness. With such a bottom design, the pressure inside the water bottle is evenly distributed.

Without this design, the alternating hot and cold temperature changes and violent vibrations during transportation can cause bottles to explode, causing waste and danger.

2. Withstand great pressure

Most carbonated soft drinks bottles are designed with the bottom of the water bottle with a raised 5-petal flower shape because shaking can accelerate the decomposition of carbonic acid, creating a large amount of air bubbles. At that time, the gas volume increases, leading to high pressure, increasing the risk of explosion and damage to the bottle.

3. Avoid shocks

The five-petal flower bottom design helps to increase the stability of the bottle when standing, especially on supermarket shelves, the bottle will have better grip, avoiding collisions and damage.

If accidentally dropped to the ground, this design helps to lower the center of gravity to the bottom of the bottle and absolutely limit the deformation of the bottle.
