Description

technical field [0001] The invention relates to the field of cosmetic bottle structures, in particular to an anti-loosening bottle mouth structure. Background technique [0002] With the improvement of people's living standards, people are keen on the pursuit of beauty, and cosmetics have become the daily necessities of the public (especially women). Most of the existing cosmetics are packaged in bottles, and when used, the cosmetics are taken out by pouring or pressing. [0003] The connection between the bottle cap or sleeve cap and the bottle body in the existing design is usually a screw connection or a snap connection. Compared with the screw connection, the production and assembly speed is faster, and the sealing performance is better at the initial stage of the engagement. Usually, the engagement structure is to set parts that engage with each other at the relative position of the bottle cap and the bottle mouth. This structure is easy to produce, simple in structure...

Problems solved by technology

[0004] However, after the snap-fit ​​structure has been used for a period of time, it will loosen or fall off. As Chinese patent (201420861023.7) discloses a cosmetic bottle, it includes a bottle body and a push-type bottle cap assembly. There is a pump body for liquid discharge and a button for pressing the liquid; the button is provided with a pipe for liquid discharge and a liquid outlet, and the liquid outlet is provided with a liquid outlet cap; the inside of the piston rod of the pump body is provided with a filter stuffed

[0005] During the use or storage of the above-mentioned cosmetic bottles, the bottle caps made of glass or plastic are affected by thermal expansion and contraction, which makes the bottle caps loose and easy to fall off, resulting in the leakage of cosmetics or cosmetic liquids, thus affecting the product. quality and effect
