A 'frame' is designed on the surface of the plastic bottle to be positioned incorrectly without moving. How can the plastic bottle mouth be tightly closed with the cap and the sealer on the bottom of the plastic bottle?

This is the part of the plastic bottle with weak mechanical properties. Plastic bottles and plastic parts are mainly bottle caps and sealers. Make it into a circle. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to choosing a material with high rigidity, the outer shape design of the plastic bottle is used to improve the rigidity and load-bearing strength of the plastic bottle.

The position of the corners of the plastic bottle and the recesses inside are all too large arcs. If the surface shape of the plastic bottle is changed, the part of the plastic bottle is relatively thinner, which can increase the grooves and ribs around the surface of the plastic bottle, and can improve the rigidity and resistance of the plastic bottle. Therefore, the bottom of the plastic bottle is generally designed like a concave shape. Therefore, these parts are designed with rounded corners.

The edge and the rotating part are type expansion, and the contact part will thicken the wall of the part. Welcome to consult!When designing a pressure-type plastic bottle, if the material is high-density polyethylene and polypropylene, the cross-section of the plastic bottle is rectangular or oval, and the material is low-density polyethylene and other flexible plastic bottles
