Description

Technical Field

[0001] The utility model belongs to the field of cosmetic packaging, and in particular relates to a pump head cover structure with strong compatibility. Background Art

[0002] With the increasing prosperity of the cosmetics market, there are more and more types of cosmetics. In order to meet market demand, cosmetics manufacturers often design unique cosmetic bottles for different types of cosmetics to highlight the uniqueness of the products. However, with the increasing number of cosmetics, the cost of designing different types of cosmetic bottles has gradually increased. In order to reduce costs, using the same type of cosmetic bottles to package different cosmetics has become an effective strategy. However, in order to distinguish different types of cosmetics, we need to spray different decorative layers on the bottle caps of cosmetic bottles. However, existing cosmetic bottle caps are usually made of a single material, which makes it a very challenging task to pursue compatibility with cosmetics and prevent chemical reactions while ensuring beautiful appearance and convenient spraying.

[0003] At present, some advanced technologies are also trying to solve this problem. For example, the patent document with publication number CN215532329U introduces a cosmetic bottle, including a bottle body and a bottle cap, and the bottle cap is directly screwed onto the bottle body. However, the bottle cap of this cosmetic bottle is also made of one material in one piece, so it is also difficult to find a balance between compatibility and aesthetic appearance. In addition, the bottle mouth of the traditional cosmetic bottle is small, which is inconvenient when assembling the pump body. It is necessary to optimize and improve the bottle mouth of the cosmetic bottle.

[0004] Therefore, we urgently need a pump head cover structure with stronger compatibility to solve the above-mentioned problems and achieve the dual goals of diversification and structural optimization of cosmetic bottles. Summary of the invention

[0005] In view of the problems in the prior art, the utility model proposes a pump head cover structure with strong compatibility, which comprises a card cover assembly covering the bottle mouth through a card cover body and a card cover cover made of different materials, so that the card cover body is compatible with cosmetics, and the card cover cover is convenient for spraying, thereby achieving the technical effect of taking into account both the chemical stability and aesthetics of the card cover assembly. Another purpose of the utility model is to optimize the bottle mouth structure of the cosmetic bottle to facilitate the rapid assembly of the pump body.

[0006] The utility model is realized as follows: a pump head cover structure with strong compatibility, which includes a bottle body, the top of the bottle body is provided with a bottle mouth with a middle portion penetrating therethrough; a vacuum pump body is installed in the bottle mouth, and a card cover assembly and a protective cover are sequentially sleeved on the outer periphery of the bottle mouth;
