Description

Technical Field

[0001] The utility model relates to the technical field of spray bottles, in particular to a spray bottle with good sealing performance. Background Art

[0002] At present, with the improvement of people's living standards, more and more people begin to use cosmetics, and most cosmetics need to be stored in glass bottles, such as perfume, nail polish, etc., and the perfume industry has developed rapidly this year. Not only more women are increasingly fond of using perfume, but also many men are more inclined to use perfume. Therefore, the output of perfume has increased year by year; and with the improvement of people's aesthetic level, the perfume glass bottle industry has also paid more and more attention to the aesthetic use and environmental protection of glass bottles; and people have also paid more and more attention to the protective performance of glass bottles for perfume.

[0003] Existing spray bottles for storing liquids such as perfume are mostly composed of a glass bottle body and a plastic atomizer nozzle screwed together. This structure has shortcomings during use. The glass bottle and the plastic skirt of the atomizer nozzle have different material properties, that is, the materials are mismatched, resulting in differences in thermal expansion coefficient and chemical resistance. Under certain conditions, such as temperature fluctuations, these differences can cause a loose seal or thread slippage. In addition, existing spray bottles for storing liquids such as perfume mostly require a direct press-fit method to install the skirt-retracting shell that is used to tighten the plastic skirt of the atomizer nozzle. This installation method requires high pressure accuracy. If the press force is too low, the installation cannot be completed. If the press force is too high, it can easily damage the glass bottle. Specialized press-fitting equipment is required, which increases assembly costs.

[0004] In view of this, the inventor hopes to design a spray bottle with good sealing performance, which does not require the use of special pressing equipment and has low assembly cost. Utility Model Content
