In the last issue, we introduced the surface treatment of glass bottles. Next, introduce the design considerations of glass bottles.

In the design process of glass bottles, the influence factors of different parts design on strength and appearance are needed, mainly from the following six points:

1.The cross-sectional design of the glass container: it mainly affects the internal pressure strength of the bottle; the more complex the shape of the cross-sectional design, the lower the strength; the closer the cross-sectional design is to a circle, the higher the strength.

2.Shoulder design of glass containers: The larger the radius of curvature of the shoulder design, the stronger its impact strength.

3.Bottom design of the glass container: This shape has a complex influence on various strength indicators; the glass container with a circular arc transition design from the bottle body to the bottom of the bottle has better comprehensive strength.

4.Bottle surface design: Convex or dot-shaped anti-impact hoops are consciously designed around the container on the surface of the bottle. Anti-shock hoops are generally distributed on the shoulders and bottoms that are most vulnerable to impact. Its main function is to resist friction and impact, and can increase the strength of glass bottles by 50%.

5.The design of the bottom surface of the bottle: the bottom surface is often designed as an inner concave surface, and a dotted strip-shaped convex pattern is designed around the outermost circle of the bottom surface. The main function is to increase the stability of the container; reduce the contact surface, reduce the thermal stress caused by temperature difference; reduce wear and tear, which is beneficial to indirectly improve the internal pressure strength and water hammer strength.

6.Design of the R angle at the lower part of the empty bottle mouth: the smaller the R angle at the anti-theft ring at the lower part of the bottle mouth, the greater the undulation of the steps, and the easier it is to break. Properly adjusting the diameter of the R angle can improve the impact strength of the bottle. As shown in the picture:

The design precautions of the glass bottle have been explained to everyone, and the next issue will introduce the glass bottle cap.We welcome more people to pay attention to our company, ZHUHAI BAOLI FOAM SPRAY PUMP CO.,LTD.
