Why are the bottoms of many glass bottles concave bottom?

2021-03-09

1. The concave bottom has stronger anti-beating ability


The glass bottle with concave bottom is 3.2 times more resistant to impact than the flat bottom. Two glass bottles of the same capacity are picked up with both hands and dropped at the same height. The glass bottle with concave bottom is safe, while the glass bottle with flat bottom is very safe. Easy to break, this is the biggest feature of glass bottles with concave bottom.

2. The concave bottom glass bottle is beautiful


The glass bottle with concave bottom looks relatively high-grade, giving a high-end aesthetic atmosphere.


3. The concave bottom glass bottle contains "less" things in the same volume


A glass bottle with a concave bottom can contain a lot of things less. For example, with the same external dimensions, the same 500ml flat-bottom glass bottle can hold 500ml of wine, while the glass bottle with a concave bottom can only hold 450ml. This is the manufacturer. The illusion given to consumers is that the bottle seems to be not small, but basically enough capacity, but it is not enough.
