[0001] This utility model relates to the technical field of cosmetic bottles, and more particularly to a vacuum cosmetic bottle. Background Technology

[0002] Cosmetic packaging containers are an important part of the cosmetic industry, and their design quality directly affects the preservation effect and user experience of cosmetics. Currently, cosmetic packaging containers on the market mainly have the following problems: (1) Inaccurate liquid control: Traditional press-type packaging containers often adopt a single-layer press structure, and the pressure transmission is uneven, which makes it difficult to accurately control the liquid volume, easily causing waste or insufficient usage; (2) Poor preservation effect of cosmetics: Ordinary packaging containers are in contact with air, and cosmetics are easily oxidized and deteriorated, especially high-end cosmetics containing active ingredients, which shorten the shelf life and affect the use effect; (3) Large amount of residue: Traditional gravity-type liquid dispensing method is inefficient, and a large amount of cosmetics are easily left at the bottom of the container, causing resource waste, especially for creams with high viscosity; (4) Poor operation stability: The single-layer press structure is prone to problems such as unstable pressing and deviation during use, affecting the user experience and liquid dispensing effect; (5) Insufficient sealing performance: The sealing structure of existing products is relatively simple, and the seal is prone to failure after long-term use, resulting in leakage or deterioration of cosmetics.

[0003] Therefore, there is a need for a cosmetic bottle that can achieve precise liquid dispensing control, has good preservation effect, and is stable and reliable in operation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is to provide a vacuum cosmetic bottle that controls the liquid dispensing channel through a pressing device to achieve precise quantitative dispensing. The pressing device is equipped with a double-layer pressing structure (upper pressing cap and lower pressing cap), which makes the force transmission more stable and avoids uneven force distribution when pressing with a single layer, resulting in uniform and abundant dispensing. At the same time, the axial pressing conforms to user habits and is simple and intuitive to operate. The double-layer structure is conducive to forming multiple seals to prevent the cosmetic from oxidizing and deteriorating.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problems is a vacuum cosmetic bottle, including...

[0008] The bottle body has an internal cavity for holding cosmetics;

[0009] The pressing device is capable of moving up and down along the axis of the bottle body and has a liquid outlet channel that connects the receiving cavity to the outside.

[0010] The pressing device includes an upper pressing cover and a lower pressing cover arranged vertically; the upper pressing cover transmits pressure through the lower pressing cover; wherein, when the upper pressing cover is pressed, the force is transmitted through the lower pressing cover to drive the cosmetic in the receiving cavity to be discharged to the outside through the liquid outlet channel.

[0011] In some embodiments, the bottle body includes an inner bottle and an outer bottle arranged inside and outside, the inner bottle forming the receiving cavity, the bottom of the receiving cavity being provided with a piston, the outer wall of the piston being in close contact with the inner wall of the inner bottle; the side of the upper pressing cap is provided with a lateral liquid outlet, the liquid outlet channel connecting the receiving cavity and the lateral liquid outlet, avoiding the problem of easy contamination from vertical liquid outlet and improving hygiene.

[0012] Using the above solution, the liquid outlet channel is controlled by a pressing device to achieve precise quantitative liquid dispensing. The pressing device is equipped with a double-layer pressing structure (upper pressing cover and lower pressing cover), which makes the force transmission more stable and avoids uneven force when pressing with a single layer, resulting in uniform and large dispensing. At the same time, the axial pressing conforms to user habits and is simple and intuitive to operate. The double-layer structure is conducive to forming multiple seals to prevent cosmetics from oxidizing and deteriorating.

[0013] In some embodiments, the upper press cover includes a pressing portion and a driving portion extending downward from the bottom end of the pressing portion; the lower press cover includes a driving engagement portion formed at its top end that engages with the driving portion.

[0014] By adopting the above solution, the cooperation between the drive unit and the drive mating unit ensures that the pressing action is efficiently transmitted to the pump body structure, the force transmission path is clear, and energy loss is reduced.

[0015] In some embodiments, the drive unit includes a mounting groove, and the drive mating part is adapted to the mounting groove; and the inner wall of the mounting groove is provided with an annular recess, and the outer wall of the drive mating part is provided with an annular protrusion that can mate with the annular recess.

[0016] By employing the above solution, the upper and lower press covers can be firmly locked together through the cooperation of the annular recess and the annular protrusion, preventing them from falling off during use.

[0017] In some embodiments, an elastic element is provided between the lower press cap and the top of the bottle body, the elastic element being able to give the lower press cap a tendency to always move upward.

[0018] In some embodiments, the lower pressing cover is provided with a mounting portion below the driving mating portion, and the mounting portion extends downward to form an extension wall to accommodate the elastic member. The elastic member is placed between the lower pressing cover and the seat body so that after the upper pressing cover is pressed and the lower pressing cover is moved downward, the elastic member will exert an upward force on the lower pressing cover after the pressing is completed, so that the lower pressing cover and the upper pressing cover return to their original state.

[0019] By adopting the above solution, the elastic element automatically returns to its original position after pressing, eliminating the need for manual operation. Furthermore, the pressure of the elastic element ensures that the liquid outlet channel closes after pressing, ensuring a sealed state and preventing leakage or air ingress.

[0020] In some embodiments, the pressing device further includes a pump body structure connected to the bottom end of the lower pressing cap. The pump body structure includes a pump body connected to the bottom end of the lower pressing cap, a sleeve disposed outside the pump body, and a check valve disposed at the bottom end of the inner cavity of the sleeve. The pump body is capable of moving up and down synchronously with the lower pressing cap, the sleeve is fixedly disposed relative to the bottle body, and the check valve is used to control the isolation or connection between the inner cavity of the sleeve and the receiving cavity.

[0021] In some embodiments, a connector is provided between the lower press cover and the pump body to connect the two together, and a sealing structure is provided at the top of the sleeve, and the outer wall of the connector can move up and down along the inner wall of the sealing structure.

[0022] Using the above solution, the check valve allows for one-way flow, preventing cosmetics from flowing back or becoming contaminated; and the vacuum pump creates a negative pressure environment, enabling vacuum-driven liquid dispensing; negative pressure-driven liquid dispensing is more efficient than gravity-driven liquid dispensing.

[0023] In some embodiments, the pump body is provided with a cavity. When the upper pressing cover is pressed, the lower pressing cover and the pump body move downwards until the cavity of the pump body and the inner cavity of the sleeve are connected. The air pressure in the inner cavity is less than the air pressure in the receiving cavity. The air pressure in the receiving cavity gives the check valve an upward force to connect the inner cavity of the sleeve and the receiving cavity. Furthermore, the air pressure in the receiving cavity drives the cosmetic in the receiving cavity to be discharged to the outside through the liquid outlet channel.

[0024] Specifically, the upper pressing cover has an upper chamber and the lower pressing cover has a lower chamber. The upper chamber, lower chamber, cavity, and inner cavity are connected in sequence to form a liquid outlet channel.

[0025] The above scheme utilizes air pressure difference to achieve stable and controllable liquid discharge, with sufficient and stable power, and can also avoid dripping; the interconnected chamber system ensures unobstructed liquid discharge path; the air pressure transmission speed is fast, and the pressing response is timely.

[0026] In some embodiments, the side wall of the pump body is provided with an opening, and the upper half of the sleeve is provided with a seal. After the pump body moves down to the point where the opening is disengaged from the seal, the cavity of the pump body and the inner cavity of the sleeve are connected.

[0027] Using the above method, the channel is opened only when a specific position is reached, and it is normally sealed to prevent leakage. Slight pressing will not release liquid, avoiding accidental waste; the clear starting point ensures that the liquid volume is consistent each time.

[0028] In some embodiments, the bottom end of the sleeve is provided with a through hole, and the check valve can close the through hole to isolate the inner cavity of the sleeve from the receiving cavity.

[0029] In some embodiments, the lower half of the housing is provided with a receiving space for accommodating the check valve, and the receiving space is sufficient to allow the check valve to release the through hole after being moved upward by air pressure, so that the cosmetic in the receiving cavity can enter the inner cavity and then flow out through the liquid outlet channel.

[0030] Using the above solution, the check valve prevents the backflow of cosmetics or air, maintains a vacuum state, ensures that the cosmetics can only flow out in one direction, and prevents outside air and impurities from entering the containment chamber; it opens automatically under air pressure without the need for additional control; it is completely sealed when static, maintaining a vacuum state, and has a simple structure.

[0031] In some embodiments, the top of the bottle is detachably connected to a base, and the sleeve is integrally formed in the middle of the base.

[0032] In some embodiments, a sealing ring is provided between the top of the base and the top of the bottle; the base is provided with an engaging space for engaging the elastic element.

[0033] The above solution allows for a detachable connection between the base and the bottle, facilitating subsequent assembly and maintenance. The sleeve and base are integrally molded, reducing assembly steps. The sealing ring enhances the bottle mouth's sealing performance, preventing liquid evaporation or leakage.

[0034] In some embodiments, a bracket is sleeved on the outside of the base, and an open end is provided in the middle of the bracket. The lower pressing cover can pass through the open end so that the pump body can cooperate with the sleeve. Furthermore, the outer edge of the lower pressing cover extends radially outward to form a flange, and the flange is confined between the bracket and the base.

[0035] In some embodiments, the bracket engages with the body to achieve synchronous movement between the two; a cover is detachably connected to the outside of the bracket to seal the pressing device.

[0036] Specifically, the downward pressing cover has a travel distance between the bracket and the base.

[0037] With the above solution, the bracket provides additional support, enhances overall rigidity, and also protects the pump body structure; the open end design provides guidance for pressing down on the cover; the flange limits the pressure between the bracket and the base to prevent excessive pressing; the cover provides additional sealing protection, preventing dust and moisture.

[0060] like Figures 1-4 As shown, this utility model provides a vacuum cosmetic bottle, including a bottle body 100, which has a receiving cavity 101 for containing cosmetics; a pressing device 200, which can move up and down along the axis of the bottle body 100, and has a liquid outlet channel 201 that connects the receiving cavity 101 to the outside; the pressing device 200 includes an upper pressing cover 202 and a lower pressing cover 203 arranged vertically; the upper pressing cover 202 transmits pressing force through the lower pressing cover 203; wherein, when the upper pressing cover 202 is pressed, the force is transmitted through the lower pressing cover 203 to drive the cosmetics in the receiving cavity 101 to be discharged to the outside through the liquid outlet channel 201. In some embodiments, the bottle body 100 includes an inner bottle 102 and an outer bottle 103 arranged inside and outside. A receiving cavity 101 is formed within the inner bottle 102. A piston 104 is disposed at the bottom of the receiving cavity 101, and the outer wall of the piston 104 is in close contact with the inner wall of the inner bottle 102. A lateral liquid outlet 2023 is disposed on the side of the upper pressing cap 202. The liquid outlet channel 201 connects the receiving cavity 101 and the lateral liquid outlet 2023, avoiding the problem of easy contamination during vertical liquid outlet and improving hygiene. Using the above solution, the liquid outlet channel 201 is controlled by the pressing device 200 to achieve precise quantitative liquid outlet. The pressing device 200 is provided with a double-layer pressing structure (upper pressing cap 202 and lower pressing cap 203), making force transmission more stable and avoiding uneven force during single-layer pressing, resulting in uniform and abundant dispensing. Simultaneously, axial pressing conforms to user habits, making operation simple and intuitive. The double-layer structure facilitates the formation of multiple seals, preventing oxidation and deterioration of cosmetics.

[0061] In some embodiments, the upper pressing cover 202 includes a pressing portion 2021 and a driving portion 2022 extending downward from the bottom end of the pressing portion 2021; the lower pressing cover 203 includes a driving engagement portion 2031 formed at its top end that cooperates with the driving portion 2022. Using the above solution, the cooperation between the driving portion 2022 and the driving engagement portion 2031 ensures that the pressing action is efficiently transmitted to the pump body structure 205, the force transmission path is clear, and energy loss is reduced. In some embodiments, the driving portion 2022 includes a mounting groove 2022a, and the driving engagement portion 2031 is adapted to fit within the mounting groove 2022a; furthermore, the inner wall of the mounting groove 2022a is provided with an annular recess 2022b, and the outer wall of the driving engagement portion 2031 is provided with an annular protrusion 2031a that can cooperate with the annular recess 2022b. By adopting the above solution, the upper pressing cover 202 and the lower pressing cover 203 can be firmly locked together by the cooperation of the annular recess 2022b and the annular protrusion 2031a, preventing them from falling off during use.

[0062] In some embodiments, an elastic element 204 is provided between the lower pressing cap 203 and the top end of the bottle body 100. The elastic element 204 provides the lower pressing cap 203 with a tendency to always move upward. In some embodiments, a mounting portion 2033 is provided below the driving engagement portion 2031 of the lower pressing cap 203. The mounting portion 2033 extends downward to form an extension wall 2033a to accommodate the elastic element 204. The elastic element 204 is positioned between the lower pressing cap 203 and the seat body 300 so that after the upper pressing cap 202 is pressed, causing the lower pressing cap 203 to move downward, the elastic element 204 will provide an upward force to the lower pressing cap 203 after the pressing is completed, causing the lower pressing cap 203 and the upper pressing cap 202 to return to their original positions. By adopting the above solution, the elastic element 204 is set so that it can automatically return to its original position after pressing, without the need for manual operation; and the pressure of the elastic element 204 ensures that the liquid outlet channel 201 is closed after pressing, ensuring a sealed state and preventing leakage or air from entering.

[0063] In some embodiments, the pressing device 200 further includes a pump body structure 205 connected to the bottom end of the lower pressing cap 203. The pump body structure 205 includes a pump body 2051 connected to the bottom end of the lower pressing cap 203, a sleeve 2052 disposed outside the pump body 2051, and a check valve 2053 disposed at the bottom end of the inner cavity of the sleeve 2052. The pump body 2051 can move up and down synchronously with the lower pressing cap 203. The sleeve 2052 is fixedly disposed relative to the bottle body 100. The check valve 2053 is used to control the isolation or connection between the inner cavity of the sleeve 2052 and the receiving cavity 101. In some embodiments, a connector 2055 is provided between the lower pressing cap 203 and the pump body 2051 to connect the two together. A sealing structure 2056 is provided at the top of the sleeve 2052, and the outer wall of the connector 2055 can move up and down along the inner wall of the sealing structure 2056. Using the above solution, the check valve 2053 allows for unidirectional flow, preventing cosmetic backflow or contamination; and the vacuum pump creates a negative pressure environment, achieving vacuum-driven liquid dispensing; negative pressure-driven liquid dispensing is more efficient than gravity-driven dispensing. In some embodiments, the pump body 2051 is provided with a cavity 2051a. When the upper pressing cover 202 is pressed, the lower pressing cover 203 and the pump body 2051 are moved downwards until the cavity 2051a of the pump body 2051 and the inner cavity of the sleeve 2052 are connected. The air pressure in the inner cavity is less than the air pressure in the receiving cavity 101. The air pressure in the receiving cavity 101 gives the check valve 2053 an upward force to connect the inner cavity of the sleeve 2052 and the receiving cavity 101. Furthermore, the air pressure in the receiving cavity 101 drives the cosmetic in the receiving cavity 101 to be discharged to the outside through the liquid outlet channel 201. Specifically, the upper pressing cover 202 has an upper chamber 2024, and the lower pressing cover 203 has a lower chamber 2034. The upper chamber 2024, lower chamber 2034, cavity 2051a, and inner cavity 2052c are sequentially connected to form a liquid outlet channel 201. Using this scheme, stable and controllable liquid discharge is achieved through air pressure difference, providing sufficient and stable power while preventing dripping. The interconnected chamber system ensures a smooth liquid outlet path; air pressure transmission is fast, and the pressing response is timely. In some embodiments, the side wall of the pump body 2051 has an opening 2051b, and the upper part of the sleeve 2052 has a sealing element 2054. After the pump body 2051 moves down until the opening 2051b disengages from the sealing element 2054, the cavity 2051a of the pump body 2051 and the inner cavity of the sleeve 2052 are connected. Using the above method, the channel is opened only when a specific position is reached, and it is normally sealed to prevent leakage. Slight pressing will not release liquid, avoiding accidental waste; the clear starting point ensures that the liquid volume is consistent each time.In some embodiments, the bottom end of the sleeve 2052 is provided with a through hole 2052a, and the check valve 2053 can close the through hole 2052a to isolate the inner cavity of the sleeve 2052 from the receiving cavity 101. In some embodiments, the lower half of the sleeve 2052 is provided with a receiving space 2052b for receiving the check valve 2053, and the receiving space 2052b is sufficient to allow the check valve 2053 to release the through hole 2052a after being moved upward by air pressure, so that the cosmetic in the receiving cavity 101 can enter the inner cavity and then flow out through the liquid outlet channel 201. With the above solution, the check valve 2053 prevents the backflow of cosmetic or air, maintains a vacuum state, ensures that the cosmetic can only flow out in one direction, and prevents external air and impurities from entering the receiving cavity 101; it opens automatically under air pressure without additional control; it is completely closed when static, maintaining a vacuum state, and has a simple structure.

[0064] In some embodiments, a base 300 is detachably connected to the top of the bottle body 100, and the sleeve 2052 is integrally formed in the middle of the base 300. In some embodiments, a sealing ring 500 is provided between the base 300 and the top of the bottle body 100; the base 300 is provided with a locking space 301 for engaging the elastic member 204. With the above solution, the detachable connection between the base 300 and the bottle body 100 facilitates subsequent assembly and maintenance; the integral forming of the sleeve 2052 with the base 300 reduces assembly steps; and the sealing ring 500 enhances the sealing of the bottle mouth, preventing liquid evaporation or leakage. In some embodiments, a bracket 400 is sleeved on the outside of the base 300, and an open end 401 is provided in the middle of the bracket 400. The lower pressing cover 203 can pass through the open end 401 so that the pump body 2051 cooperates with the sleeve 2052. Furthermore, the outer edge of the lower pressing cover 203 extends radially outward to form a flange 2032, and the flange 2032 is constrained between the bracket 400 and the base 300. In some embodiments, the bracket 400 is engaged with the base 300 to achieve synchronous movement between the two. A cover 600 is detachably connected to the outside of the bracket 400 to seal the pressing device 200. Specifically, the lower pressing cover 203 has a travel distance between the bracket 400 and the base 300. With the above solution, the bracket 400 provides additional support, enhances overall rigidity, and also protects the pump body structure 205; the design of the open end 401 provides guidance for the pressing cover 203; the flange 2032 limits the pressure between the bracket 400 and the seat 300 to prevent excessive pressing; the cover 600 provides additional sealing protection, dustproof and moistureproof.

The pump body structure (205) includes a pump body (2051) connected to the bottom end of the lower pressing cap (203), a sleeve (2052) disposed outside the pump body (2051), and a check valve (2053) disposed at the bottom end of the inner cavity of the sleeve (2052). The pump body (2051) can move up and down synchronously with the lower pressing cap (203). The sleeve (2052) is fixedly disposed relative to the bottle body (100). The check valve (2053) is used to control the isolation or connection between the inner cavity of the sleeve (2052) and the receiving cavity (101).

6. The vacuum cosmetic bottle according to claim 5, characterized in that: The pump body (2051) is provided with a cavity (2051a). When the upper pressing cover (202) is pressed, the lower pressing cover (203) and the pump body (2051) are moved down until the cavity (2051a) of the pump body (2051) and the inner cavity of the sleeve (2052) are connected. The air pressure in the inner cavity is less than the air pressure in the receiving cavity (101). The air pressure in the receiving cavity (101) gives the check valve (2053) an upward force to connect the inner cavity of the sleeve (2052) and the receiving cavity (101). Furthermore, the air pressure in the receiving cavity (101) drives the cosmetic in the receiving cavity (101) to be discharged to the outside through the liquid outlet channel (201).

7. The vacuum cosmetic bottle according to claim 6, characterized in that: The pump body (2051) has an opening (2051b) on its side wall, and the upper part of the sleeve (2052) is provided with a sealing element (2054). After the pump body (2051) moves down to the opening (2051b) and disengages from the sealing element (2054), the cavity (2051a) of the pump body (2051) and the inner cavity of the sleeve (2052) are connected.

8. The vacuum cosmetic bottle according to claim 6, characterized in that: The bottom end of the sleeve (2052) is provided with a through hole (2052a), and the check valve (2053) can close the through hole (2052a) to isolate the inner cavity of the sleeve (2052) from the receiving cavity (101).

9. The vacuum cosmetic bottle according to claim 5, characterized in that: The top of the bottle body (100) is detachably connected to a base (300), and the sleeve (2052) is integrally formed in the middle of the base (300).

10. The vacuum cosmetic bottle according to claim 9, characterized in that: The seat (300) is fitted with a bracket (400) on its outside. The bracket (400) has an open end (401) in the middle. The lower pressing cover (203) can pass through the open end (401) so that the pump body (2051) can cooperate with the sleeve (2052). Furthermore, the outer edge of the lower pressing cover (203) extends radially outward to form a flange (2032), which is confined between the bracket (400) and the seat (300).
