Description

Technical Field

[0001] This utility model belongs to the field of cosmetic packaging jar technology, specifically a double-compartment vacuum face cream jar. Background Technology

[0002] As people's living standards improve, their demand for cosmetics is also increasing. The aesthetic appeal of cosmetic packaging often directly influences whether consumers choose a particular product. Current cosmetic packaging primarily achieves its attractive design through variations in overall shape, surface treatment, surface patterns, and the combination of transparent and opaque elements.

[0003] Some cosmetics are made by mixing multiple serums in a certain proportion. These serums, when undisturbed, can generally be stored for a long time without spoiling. However, after mixing, their chemical properties change, and their shelf life decreases. Therefore, some cosmetic packaging allows for the repackaging of serums, enabling consumers to mix them themselves after purchasing the product to achieve a longer shelf life. Even with repackaged serums, the consistent opening during filling and the sealing only after all the serum has been filled pose a risk of mixing during the filling process. Furthermore, it's almost impossible to find designs that utilize the layering of colors or variations in the amount used to create unique visual effects during cosmetic use. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a dual-compartment vacuum cream jar. This dual-compartment vacuum cream jar can utilize the color superposition of the cream components inside and present a unique visual effect depending on the amount of cream used during use. In addition, it can effectively prevent the two components of the cream from accidentally mixing during filling.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a dual-compartment vacuum cream jar, comprising a jar body assembly and a jar lid assembly. The jar body assembly includes a transparent jar body and an inner jar lid. The transparent jar body has an outer annular jar with a top opening and an inner annular jar with a bottom opening. The transparent jar body has a suction pipe with a top opening and a bottom connection to the inner annular jar. The bottom of the inner annular jar is sealed by the inner jar lid, and the top of the outer annular jar is sealed by the jar body assembly. Air holes are provided at the top of the inner annular jar and the bottom of the outer annular jar. A first piston that slides upward from the bottom is provided in the outer annular jar, and a second piston that slides downward from the top is provided in the inner annular jar. A first vacuum pump and a second vacuum pump are provided on the jar lid assembly. The suction port of the first vacuum pump is located inside the outer annular jar, and the suction port of the second vacuum pump is located inside the suction pipe. This dual-compartment vacuum face cream jar has a transparent body, and the inner and outer annular compartments contain two different components of the face cream. During use, the first piston slides upward and the second piston slides downward, allowing the colors of the face cream components to overlap and creating a unique visual effect depending on the amount of face cream used. Furthermore, because the openings of the outer and inner annular compartments are in different positions and are sealed separately, the two components can be effectively prevented from accidentally mixing during filling.

[0006] In the above technical solution, preferably, the can lid assembly includes a squeeze cap, with the tops of the first vacuum pump and the second vacuum pump connected to the squeeze cap. The squeeze cap is provided with a first discharge pipe communicating with the discharge port of the first vacuum pump and a second discharge pipe communicating with the discharge port of the second vacuum pump. The top of the squeeze cap is provided with a first discharge hole communicating with the first discharge pipe and a second discharge hole communicating with the second discharge pipe. This structure allows for the simultaneous pumping of two components through the squeezing of the squeeze cap, ensuring that the two components do not meet within the discharge pipes during the pumping process. They only mix when the user uses the product, thus avoiding a decrease in the shelf life of the mixed cream components in the discharge pipes due to the two components meeting within the discharge pipes and not being used for a long time.

[0007] In the above technical solution, preferably, a positioning bracket is provided on the extrusion cap at the connection point with the first discharge pipe, and a plurality of first discharge holes are arranged around the center of the positioning bracket. A positioning hole is provided at the center of the positioning bracket, and a first elastic sealing element is engaged within the positioning hole. The first elastic sealing element elastically seals the plurality of first discharge holes. This structure can elastically seal the first discharge holes, preventing the two components from mixing and also preventing the components inside the first discharge pipe from contacting air.

[0008] In the above technical solution, preferably, the sidewall of the second discharge hole extends inward with a locking protrusion, and a second elastic sealing member is fitted inside the locking protrusion, which elastically seals the second discharge hole. This structure can elastically seal the second discharge hole, preventing the two components from mixing and also preventing the components inside the second discharge pipe from contacting air.

[0009] In the above technical solution, preferably, a first vacuum pump is provided on each of the two sides opposite the second vacuum pump on the extrusion cap, and the suction ports of the two first vacuum pumps are located inside the outer annular chamber. This structure ensures that the force on both sides of the extrusion cap is more balanced when the extrusion cap is pressed, and also serves to set the mixing ratio of the two components.

[0010] In the above technical solution, preferably, the extrusion cap includes a head cap and a guide tube, the guide tube being snapped into the extrusion cap to form the first discharge pipe and the second discharge pipe. This structure facilitates the processing and formation of the first and second discharge pipes on the extrusion cap.

[0011] In the above technical solution, preferably, the can lid assembly includes a shoulder sleeve that snaps onto the transparent can body, and a vacuum pump positioning seat is sandwiched between the shoulder sleeve and the transparent can body. The vacuum pump positioning seat is equipped with a first vacuum pump and a second vacuum pump, and the vacuum pump positioning seat seals the top of the outer annular compartment. The shoulder sleeve improves aesthetics, and the vacuum pump positioning seat facilitates the sealing of the outer annular compartment.

[0012] In the above technical solution, preferably, the inner annular compartment and the outer annular compartment are concentrically arranged circular compartments.

[0013] In the above technical solution, preferably, a base support is snapped onto the bottom of the transparent tank. The base support serves both a decorative purpose and protects the inner compartment lid, preventing accidental damage to the inner compartment lid.

[0014] Compared with the prior art, this utility model has the following advantages: Because the body of this dual-compartment vacuum face cream jar is transparent, and the inner and outer annular compartments are respectively filled with two components of face cream, during use, the first piston slides upward and the second piston slides downward, thereby utilizing the color superposition of the internal face cream components and presenting a unique visual effect due to the amount of face cream used during use; moreover, because the opening positions of the outer and inner annular compartments are different and they are sealed separately, the two components can be effectively prevented from accidentally mixing during filling.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 9 A dual-compartment vacuum face cream jar includes a jar body assembly 1 and a jar lid assembly 2. The jar body assembly 1 includes a transparent jar body 3 and an inner compartment cover 4. The transparent jar body 3 has an outer annular compartment 5 with a top opening and an inner annular compartment 6 with a bottom opening. The transparent jar body 3 has a suction pipe 7 with a top opening and a bottom connection to the inner annular compartment 6. The bottom of the inner annular compartment 6 is sealed by the inner compartment cover 4, and the top of the outer annular compartment 5 is sealed by the jar body assembly 1. Air holes 8 are provided at the top of the inner annular compartment 6 and the bottom of the outer annular compartment 5. A first piston 9 that slides from bottom to top is provided in the outer annular compartment 5, and a second piston 10 that slides from top to bottom is provided in the inner annular compartment 6. A first vacuum pump 11 and a second vacuum pump 12 are provided on the jar lid assembly 2. The suction port of the first vacuum pump 11 is located in the outer annular compartment 5, and the suction port of the second vacuum pump 12 is located in the suction pipe 7. This dual-compartment vacuum face cream jar has a transparent body, and the inner annular compartment 6 and the outer annular compartment 5 contain two different components of the face cream. During use, the first piston 9 slides upward and the second piston 10 slides downward, which allows the colors of the face cream components inside to overlap and present a unique visual effect depending on the amount of face cream used. In addition, because the opening positions of the outer annular compartment 5 and the inner annular compartment 6 are different and they are sealed separately, the two components can be effectively prevented from accidentally mixing during filling.

[0025] This unique visual effect depends on the color of the cream components, which may be transparent, semi-transparent, or opaque. During the use of the cream, the first piston 9 slides upward, causing the bottom of the inner annular compartment 6 to gradually become transparent, and the transparent area gradually increases. As the second piston 10 slides downward, the top of the outer annular compartment 5 gradually becomes transparent, and the transparent area gradually increases, thus presenting a unique visual effect during use.

[0026] The inner chamber cap 4 is made of aluminum foil. During filling, the inner chamber cap 4 made of this material can easily seal the inner annular chamber 6 through an electromagnetic induction aluminum foil sealing device.

[0027] In this embodiment, in order to reduce the space inside the suction tube 7 so that the second vacuum pump 12 can smoothly draw up the cream components, a filling tube is also sleeved inside the suction tube 7, with the bottom connected to the inner annular chamber 6 and the top connected to the suction port of the second vacuum pump 12.

[0028] In this embodiment, the lid assembly 2 includes a squeeze cap 13. The tops of the first vacuum pump 11 and the second vacuum pump 12 are connected to the squeeze cap 13. The squeeze cap 13 is provided with a first discharge pipe 14 communicating with the discharge port of the first vacuum pump 11 and a second discharge pipe 15 communicating with the discharge port of the second vacuum pump 12. The top of the squeeze cap 13 is provided with a first discharge hole 16 communicating with the first discharge pipe 14 and a second discharge hole 17 communicating with the second discharge pipe 15. With this structure, the two components can be pumped out simultaneously by the squeeze cap 13, and the two components do not meet in the discharge pipe during the pumping process. They only mix when the user uses the product, avoiding the decrease in shelf life of the mixed cream components in the discharge pipe due to the two components meeting in the discharge pipe and not being used for a long time.

[0029] In this embodiment, a positioning bracket 18 is provided on the extrusion cap 13 at the connection point with the first discharge pipe 14. A plurality of first discharge holes 16 are arranged around the center of the positioning bracket 18, and a positioning hole 19 is provided at the center of the positioning bracket 18. A first elastic sealing member 20 is fitted into the positioning hole 19, and the first elastic sealing member 20 elastically seals the plurality of first discharge holes 16. This structure can elastically seal the first discharge holes 16, preventing the two components from mixing and also preventing the components in the first discharge pipe 14 from contacting air.

[0030] In this embodiment, a locking protrusion 21 extends inward from the sidewall of the second discharge hole 17, and a second elastic sealing member 22 is fitted inside the locking protrusion 21, which elastically seals the second discharge hole 17. This structure can elastically seal the second discharge hole 17, preventing the two components from mixing and also preventing the components in the second discharge pipe 15 from contacting air.

[0031] In this embodiment, both the first elastic sealing member 20 and the second elastic sealing member 22 are elastic members made of silicone.

[0032] In this embodiment, a first vacuum pump 11 is provided on each of the two sides opposite to the second vacuum pump 12 on the extrusion cap 13, and the suction ports of the two first vacuum pumps 11 are located inside the outer annular chamber 5. This structure ensures that the force on both sides of the extrusion cap 13 is relatively balanced when the extrusion cap 13 is pressed, and also serves to set the mixing ratio of the two components.

[0033] In this embodiment, the extrusion cap 13 includes a head cap 23 and a guide tube 24. The guide tube 24 is snapped into the extrusion cap 13 to form a first discharge pipe 14 and a second discharge pipe 15. Both the head cap 23 and the guide tube 24 are made of PP material. This structure facilitates the processing and formation of the first discharge pipe 14 and the second discharge pipe 15 on the extrusion cap 13.

[0034] In this embodiment, the can lid assembly 2 includes a shoulder sleeve 25 that snaps onto the transparent can body 3. A vacuum pump positioning seat 26 is sandwiched between the shoulder sleeve 25 and the transparent can body 3. A first vacuum pump 11 and a second vacuum pump 12 are mounted on the vacuum pump positioning seat 26. The vacuum pump positioning seat 26 seals the top of the outer annular compartment 5. The shoulder sleeve 25 improves the aesthetics, and the vacuum pump positioning seat 26 facilitates the sealing of the outer annular compartment 5.

[0035] In this embodiment, the inner annular compartment 6 and the outer annular compartment 5 are concentric annular compartments.

[0036] In this embodiment, a base support 27 is snapped onto the bottom of the transparent can 3. The base support 27 is made of ABS material. The base support 27 serves both a decorative purpose and protects the inner compartment cover 4 from accidental damage.

[0037] The filling method for the aforementioned dual-compartment vacuum face cream jar includes the following steps: 1) Place the transparent jar body 3 upright and inject the first component of the face cream into the opening at the top of the outer annular compartment 5; 2) Cover the outer annular compartment 5 with the lid assembly 2; 3) Invert the transparent jar body 3 with the outer annular compartment 5 covered, and inject the second component of the face cream into the opening at the bottom of the inner annular compartment 6; 4) Place the inner compartment cap 4 made of aluminum foil into the inner annular compartment 6 and press down the bottom support 27; 5) Seal the inner annular compartment 6 using an electromagnetic induction aluminum foil sealing device. This filling method, by separately filling and sealing the outer annular compartment 5 and the inner annular compartment 6, effectively avoids accidental mixing of the two components during filling.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
