Process of shaped glass bottles

Time:2018-12-22

Shaped glass bottles refer to various glass bottles with non-circular cross sections, such as three-way bottles, square bottles, square bottles, oval bottles, and the like. Through the unique bottle shape design, the glass bottle not only satisfies the requirements of product packaging, but also makes the container have certain art, decoration and display value, satisfying the spirit and psychological needs of consumers. In addition, the shaped bottles are also relatively good pseudo-functions in technology. Most of the shaped bottles are complex in structure, high in processing technology, difficult to make, and difficult to control, thus making the shaped bottles have technical anti-counterfeiting functions.

The bottom of the glass bottle is generally designed to be concave, which reduces the contact points in the contact plane and increases stability. The bottom of the bottle and the root of the bottle adopt a circular arc transition, and the transition arc is large, which is beneficial to improve the strength of the bottle, but if the arc is too large, the support area will be reduced and the stability of the glass bottle will be reduced. Under the condition that the quality of the glass bottle is constant, the minimum thickness of the bottom of the bottle is used as the design requirement. The thickness ratio of the bottom of the bottle is specified, and the thickness of the bottle is required to have a small difference in thickness and reduce internal stress.
