Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cosmetic packaging, in particular to an anti-oxidation cosmetic bottle. Background Art
[0002] Cosmetics are popular among consumers because of the active ingredients they contain, which often have multiple functions such as anti-oxidation, anti-aging, and whitening. However, these active ingredients are prone to oxidation reactions after contact with air, especially when they encounter oxygen, resulting in changes in the structure of the ingredients, reduced efficacy, or even failure. The oxidation process may also cause changes in the texture and color of cosmetics, affecting the sensory quality of the product and the consumer's experience of use. In addition, the free radicals released by the oxidation reaction may cause additional damage to the skin, offsetting the original skin care effect of the cosmetics.
[0003] Most cosmetic bottles in the prior art are simple containers that lack effective anti-oxidation design. When cosmetics are squeezed out of the bottle, negative pressure is formed due to the reduction of the material in the bottle. When the negative pressure reaches a certain level, air will be sucked into the bottle, causing the cosmetics to come into contact with oxygen, accelerating the oxidation process. Therefore, developing a cosmetic bottle that can effectively isolate air and slow down the oxidation reaction is of great significance for maintaining the stability and activity of cosmetic ingredients, extending the shelf life of the product, and improving the consumer experience. Utility Model Content
[0004] In order to solve the above problems in the prior art, the utility model provides an anti-oxidation cosmetic bottle, which can reduce the volume of the bottle body as the cosmetics are squeezed out, thereby preventing air from flowing back into the bottle body from the extrusion position and causing oxidation of the cosmetics.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: an anti-oxidation cosmetic bottle, comprising a bottle body, an extrusion device and a volume adjustment base, the volume adjustment base having the same shape as the bottle body, the volume adjustment base being arranged inside the bottle body, the volume adjustment base being movable up and down inside the bottle body, the bottom of the bottle body being provided with an opening, the extrusion device comprising a negative pressure extrusion head and an extrusion tube. After the cosmetics are extruded by the extrusion device, negative pressure is generated in the space above the volume adjustment base, the atmospheric pressure pushes the volume adjustment base upward, thereby reducing the space above the volume adjustment base, and preventing air from entering the bottle body through the extrusion head of the extrusion device.
[0006] Furthermore, it also includes a bottom cover, which is connected to the bottom of the bottle body through threads to prevent the volume adjustment base from falling off.
[0007] Furthermore, an elastic isolation sleeve is connected to the bottom of the bottle body, and the maximum stretching length of the elastic isolation sleeve is equal to the height of the bottle body, which can further prevent air from entering the space above the volume adjustment base.
[0008] Furthermore, the top of the bottle body is connected with the elastic isolation sleeve, and the cosmetics are placed in the elastic isolation sleeve, which can further prevent air from entering the space above the volume adjustment base.
[0009] Furthermore, the volume adjustment base is a hollow shell, which reduces weight and facilitates being pushed upward by atmospheric pressure.
[0010] Furthermore, the height of the volume adjustment base is greater than or equal to one centimeter, so as to prevent the volume adjustment base from turning over and preventing the volume adjustment base from getting stuck or falling off.
[0011] Furthermore, it also includes a one-way check valve, which is arranged on the extrusion tube of the extrusion device to prevent air from flowing back into the bottle body through the negative pressure extrusion head. Since the volume of the bottle body is variable, no negative pressure will be formed to cause the bottle body to be flattened by atmospheric pressure.
[0012] The utility model has the following beneficial effects: anti-oxidation protection, as the amount of cosmetics decreases, the volume-adjusting bottom support can move upward under the action of atmospheric pressure to reduce the volume, thereby avoiding the formation of negative pressure inside the bottle body and preventing air from flowing back into the bottle body, and effectively preventing the cosmetics from being oxidized; the volume-adjusting bottom support can move up and down inside the bottle body, dynamically adjusting the internal space to adapt to the remaining amount of cosmetics at different use stages; the negative pressure generated by the extrusion device helps to push the volume-adjusting bottom support up, further reducing the contact between air and cosmetics; the bottom cover is connected to the bottom of the bottle body by threads, thereby enhancing the stability of the overall structure and preventing the volume-adjusting bottom support from falling off; the elastic isolation sleeve connected to the bottom and top of the bottle body provides additional protection to prevent air from entering the cosmetics storage space; the volume-adjusting bottom support is designed as a hollow shell, thereby reducing the weight and facilitating upward movement; the height of the volume-adjusting bottom support is designed to be greater than or equal to one centimeter, thereby preventing the volume-adjusting bottom support from turning over or getting stuck and ensuring its normal operation; the one-way check valve arranged on the extrusion tube prevents air from flowing back through the negative pressure extrusion head and ensures the safety of the use process.

The bottom of the bottle body 1 is provided with an opening, and the extrusion device 2 comprises a negative pressure extrusion head 21 and an extrusion tube 22. After the cosmetics are extruded by the extrusion device 2, negative pressure is generated in the space above the volume adjustment base 3, and the atmospheric pressure pushes the volume adjustment base 3 upward, so that the space above the volume adjustment base 3 is reduced, thereby preventing air from entering the bottle body 1 through the extrusion head 21 of the extrusion device 2.
