Why are most beverage bottles round?

1. Mathematical perspective, cost saving. When the circumference is constant, the circle has the largest area, and the nearly circular shape can save raw materials. This is also the reason why the circle was promoted the earliest.

2. Aesthetic perspective, it is ugly over time. The habit of long-term development makes the circle more in line with aesthetics.

3. Manufacturing perspective, simple process. Whether it is glass or plastic, the circle is relatively easy to make, and other shapes need to be re-made molds, and the process is also difficult to guarantee.

4. Behavioral perspective, easy to use. The circle conforms to the human body and is easy to grip.
