Although these materials have played an important role in storing and transporting liquid products, they still have some problems to be solved in practical application:
[0004] 1. Bottle deformation caused by air pressure changes: During transportation or storage, due to changes in environmental temperature, altitude and other factors, the air pressure inside and outside the bottle may differ. This air pressure difference often leads to the expansion or contraction of the bottle body, thereby affecting the integrity of the package and the stability of the product. For traditional hard packing bottles, they lack effective air pressure regulation mechanisms and are difficult to cope with the challenges brought by air pressure changes.
[0005] 2. Liquid backflow pollution: When pouring liquid, if the bottle mouth is not reasonably designed or the sealing performance is poor, the liquid may flow back into the bottle, causing pollution. This backflow phenomenon not only affects the quality of the product, but also may cause safety hazards.
