why do sprite bottles have dimples
Bottles of soft drinks and soda drinks, especially those made of plastic, are not flat-bottomed. The foot of the bottles usually has 5 bumps (ripple). You will not see these bumps in water bottles. Water bottles have small recesses to improve the stability of the bottle.
The bumps or ripples at the bottom of the bottle increase the resistance of the bottle.
why do plastic bottles have a concave bottom
Another reason is that most soft drinks are pressurized by gas filling; the plastic bottle must be able to withstand the pressure. It should also absorb shocks in case of an accidental drop of the bottle. The next time you buy a soft drink, try crushing the bottle. You can easily crush the top but you will have trouble crushing the foot of the bottle. These bumps at the bottom of a bottle also improve stability...
The size of the bottle continues to decrease upwards; it's lowering the center of gravity. This improves the stability of the bottle. In the cans, the bottom is domed inward, which gives good stability to the box.
Bottles of soft drinks must withstand the pressure due to carbonation. The 5-point socks are designed to better withstand the pressure. A 5 point background is not the only way, it's just a way that works well and is commonly used.

| why do water bottles have flat bottoms |
Bottled water is not carbonated, so it is not necessary to have a sharp bottom. A flat bottom uses less plastic and withstands fall tests better.
Soft drinks are served fresh. When a liquid is cooled, its volume changes and the bottle must not be veiled because of this change in volume. The corner or tip of the bump may slightly expand / contract without breaking, allowing the change in liquid volume to be taken into account.
Explanation:
Take a sheet of paper and fold it. You can easily fold the paper. Now, fold any side of the sheet and try folding it. You will now feel some resistance. Now roll the paper in a pipe and try to fold it. It will be a bit difficult to fold the paper pipe. Bending of any material increases its strength and stiffness. This is due to the fact; rolling the paper increases its moment of inertia around the axis of bending.
