The strength of the lightweight bottle made by the glass bottle manufacturer is not only related to the glass composition, microscopic and macroscopic defects in the glass, but also has a lot to do with the shape of the bottle. Reasonable structural design can make the stress distribution uniform, uniform cooling and increase the ” Elasticity”, so that the internal pressure resistance and impact strength can be improved. Therefore, as long as the design of the bottle shape and wall thickness distribution is reasonable, the lightweight bottle will not cause a decrease in strength.

When designing the glass bottle shape, it is mainly based on the principle that the closer the glass product is to a spherical shape, the less likely it is to generate stress concentration, thereby increasing the strength. The general principles of strength and light weight bottle shape design are as follows:
① Shrink the bottle root, which can increase the strength of the bottle and improve the glass distribution in this part.
②Avoid shaped bottles. The bump on the bottom of the bottle should be as shallow as possible.
③ Do not use long-necked bottles as much as possible. The long-necked bottle only increases the height of the bottle but cannot increase the capacity of the bottle. In addition, the bottleneck is easy to break, and it is not easy to reduce the amount of glass used in the neck.
④ Avoid sharp angles on the shoulder of the bottle, and use a tapered high hall with a smooth transition.
⑤ Avoid seams at the corners, otherwise it will make it difficult to maintain the mold, increase the number of bottle defects, make the blank design difficult, and make the glass distribution at the corners uneven.
⑥ Use a bottle mouth with the smallest wall thickness to avoid excessive overlapping of threads. The neck reinforcement ring should be as small as possible or completely eliminated.
⑦The distance from the top of the bottle mouth to the beginning of the thread should be as small as possible. The bottle mouth height is also as small as possible.
⑧Reduce the total height of the bottle.
