When Taizhou Dongbang Plastic Industry Co., Ltd. were designing the squeeze plastic bottle.

In this way, the wall thickness of the modified part will be larger. At the edge and corner, when the parison is blown to the place where it comes into contact, the wall thickness of this part will also be smaller. Therefore, the edge of the plastic bottle and the place where the feet are ground need to be designed with rounded corners.
