In addition, the cost of PET material is relatively low, which is conducive to controlling the overall cost of the product. When filling, the bottle is inverted for pouring.

[0031] The bottle body 1 is provided with a receiving chamber 13 inside, the top of the bottle body 1 is provided with a pumping assembly 2, and the bottle cap 3 is detachably connected to the top of the bottle body 1, such as by threaded connection or snap connection. The pumping assembly 2 is accommodated inside the bottle cap 3.

[0032] The bottom of the bottle body 1 is provided with a bottom cover 4 for discharging the gas inside the bottle body 1. The bottom cover is provided to meet the requirement of wide-mouth bottom filling of cosmetics, and the vent hole heat-sealing structure is provided to ensure the sealing of the bottom part after filling is completed.

[0033] The bottom cover 4 includes a bottom shell 401, which is arranged at the bottom of the bottle body 1. The outer wall surface of the exhaust structure 402 is connected to the inner wall surface of the bottom shell 401 by threads. A fixing member 404 is arranged inside the bottom shell 401. When the bottom shell 401 is connected to the exhaust structure 402, the fixing member 404 is used to abut against the blocking gasket 403. The exhaust hole of the exhaust structure 402 is to ensure that the air in the bottle can be discharged after the filling is completed. The exhaust structure 402 has an exhaust hole and a heat-sealing structure at the center position, which is used to discharge the air in the bottle, and then the blocking gasket 403 is a heat-sealing gasket (used to seal the exhaust hole) that abuts against the fixing member 404.

[0034] An exhaust structure 402 is provided at the bottom of the bottle body 1 . A through exhaust hole is provided at the center of the exhaust structure 402 . The exhaust hole is connected to the accommodating cavity 13 . A sealing gasket 403 is provided at one end of the exhaust hole away from the accommodating cavity.

[0035] The utility model modularizes the bottle body 1, the bottom shell 401, the exhaust structure 402, the sealing gasket 403 and the fixing part 404. When in use, the various components can be assembled first, and then the inside of the bottle body 1 is vacuumed, and then the bottle body 1 is sealed with the bottom cover 4, and finally the cosmetics are injected into the bottle body 1.

[0036] By arranging the bottle body 1, the bottom shell 401, the exhaust structure 402, the blocking gasket 403, the fixing member 404 and the air vent, when the user presses the pumping assembly 2 and resets it, the air inside the bottle body 1 can be discharged in time to avoid oxidation of the cosmetics inside the bottle body 1, thereby helping to extend the shelf life of the cosmetics inside the bottle body 1;

[0037] A pressure stabilizing chamber 5 is reserved between the bottom shell 401 and the exhaust structure 402. The exhaust structure 402 and the sealing gasket 403 are integrally formed. The design of the pressure stabilizing chamber 5 helps to discharge the gas in the bottle in time, reducing the chance of cosmetics contacting with air, thereby preventing the ingredients in the cosmetics from being oxidized. Oxidation is one of the main reasons for the deterioration of cosmetics. By reducing the oxidation reaction, the shelf life of cosmetics can be significantly extended. In addition, for many cosmetics, the stability of their active ingredients is the key to maintaining the product effect. The design of the pressure stabilizing chamber 5 helps to maintain the stability of the environment in the bottle, reduce the interference of external factors on the active ingredients, thereby maintaining the activity and effectiveness of the cosmetics;

[0038] Two groups of air holes 6 are provided at the inner bottom of the bottom shell 401. The two groups of air holes 6 are symmetrically arranged. The two groups of air holes 6 can more quickly achieve the balance of the air pressure inside and outside the bottle body 1. When the air pressure inside the bottle body 1 decreases due to the reduction of cosmetics, the external air can quickly enter the pressure stabilizing chamber 5 through the two groups of air holes 6, thereby maintaining the stability of the air pressure inside the bottle. In addition, during the process of the cosmetics being squeezed out, the air pressure inside the bottle body 1 will change. The design of the two groups of air holes 6 helps to reduce such air pressure fluctuations, so that the cosmetics can flow out more smoothly.

[0039] The pumping assembly 2 includes a pump housing 201, the bottom of which is fixedly connected to the top of the bottle body 1, a pressure pump 202 is installed inside the pump housing 201, and a nozzle 203 is fixedly connected to the top of the pressure pump 202. By setting the pump housing 201, the pressure pump 202 and the nozzle 203 for coordinated use, the user can press the pressure pump 202 to discharge the cosmetics inside the bottle body 1 from the nozzle 203;

[0040] The inner bottom of the nozzle 203 is provided with an inner ring sleeve 7, and the top of the pressure pump 202 is connected with an outer ring sleeve 8 adapted to the inner ring sleeve 7, and the inner ring sleeve 7 is plugged into the inner cavity of the outer ring sleeve 8. By setting the inner ring sleeve 7 and the outer ring sleeve 8 in cooperation, the pressure pump 202 is limited.

[0041] A return spring 11 is arranged on the outside of the pressure pump 202, and the two ends of the return spring 11 are connected to the pump housing 201 and the pressure pump 202 respectively. By arranging the return spring 11, the pressure pump 202 is reset. The return spring 11 can ensure that the pressure pump 202 can be quickly and smoothly reset to the initial position after each pressing, so that the user can feel a smoother and more fluent pressing experience during continuous use without additional force or waiting for the pressure pump 202 to reset itself. In addition, when using cosmetics for a long time, if the pressure pump 202 cannot be reset smoothly, the user may feel hand fatigue, and the design of the return spring 11 effectively reduces this fatigue, making the use process easier and more comfortable;

[0042] The top of the fixing member 404 is provided with an annular step groove 12 adapted to the blocking gasket 403, and the bottom of the blocking gasket 403 is clamped in the inside of the annular step groove 12. The annular step groove 12 is provided to seal the fixing member 404, which is beneficial to further improve the air tightness of the fixing member 404 and the blocking gasket 403.

[0043] An annular groove 9 is provided on the inner wall of the bottle cap 3, and an annular protrusion 10 corresponding to the annular groove 9 is provided on the outer wall of the bottle body 1. The annular protrusion 10 is clamped in the inner part of the annular groove 9. The annular groove 9 and the annular protrusion 10 are used in coordination to limit the bottle cap 3, so that the user can disassemble and assemble the bottle cap 3 conveniently. The material of the bottle cap 3 is set to be ABS. ABS plastic is made by blending 25% acrylonitrile (A), 20% polybutadiene rubber (B) and 55% styrene (S). This ratio makes ABS achieve a perfect balance between hardness and firmness. This characteristic makes The ABS bottle cap 3 can withstand a certain pressure and is not easily deformed or damaged, thereby ensuring the sealing and durability of the cosmetic vacuum bottle. In addition, ABS has good chemical resistance, which means that it can effectively resist various chemical components that may be contained in cosmetics, such as solvents, fragrances, etc., thereby ensuring the quality and stability of cosmetics. At the same time, ABS can be processed by injection molding, extrusion molding and other methods, which makes the manufacturing process of ABS bottle cap 3 more flexible and efficient. Injection molding is one of the commonly used molding methods in cosmetic packaging. It can produce a large number of bottle caps 3 with complex shapes and precise sizes in a short time.
