Description

Technical Field

[0001] The invention belongs to the technical field of cosmetic packaging cans, and in particular is a double-compartment vacuum cream can and a filling method thereof. Background Art

[0002] As people's living standards improve, their demand for cosmetics is also increasing. The aesthetics of cosmetic packaging jars in many cases directly affects whether consumers choose the cosmetics. Existing cosmetic packaging jars mainly achieve beautiful appearance design by changing the overall contour, surface treatment, surface pattern, and combining transparent and non-transparent parts.

[0003] Some cosmetics are made by mixing multiple stock solutions in a certain proportion. These stock solutions can generally be stored for a long time without deterioration in the unmixed state. However, after mixing, the chemical properties change and the shelf life decreases. Therefore, some cosmetic packaging can be divided into stock solutions. After consumers buy the cosmetics, they can mix these stock solutions by themselves to obtain cosmetics with a longer shelf life. Even for some cosmetic packaging with divided stock solutions, since the opening is consistent during filling and the cap is not sealed until all the stock solutions are filled, there is a risk of stock solutions mixing during filling. It is almost impossible to see designs that use the color superposition of internal cosmetics and the change in usage to achieve a unique visual effect during the use of cosmetics. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a double-compartment vacuum cream jar and a filling method thereof. The double-compartment vacuum cream jar can utilize the color superposition of the cream components inside and present a unique visual effect due to the amount of cream inside during use, and can effectively avoid accidental mixing of the two components of the cream during canning.

[0005] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a double-compartment vacuum cream jar, comprising a jar body assembly and a jar cover assembly, the jar body assembly comprising a transparent jar body and an inner jar cover, the transparent jar body is provided with an outer annular jar with a top opening and an inner annular jar with a bottom opening, the transparent jar body is provided with a suction pipe with a top opening and a bottom connected to the inner annular jar, the bottom of the inner annular jar is sealed by the inner jar cover, the top of the outer annular jar is sealed by the jar body assembly, the top of the inner annular jar and the bottom of the outer annular jar are both provided with air holes, the outer annular jar is provided with a first piston sliding from bottom to top, the inner annular jar is provided with a second piston sliding from top to bottom, the jar cover assembly is provided with a first vacuum pump and a second vacuum pump, the suction port of the first vacuum pump is located in the outer annular jar, and the suction port of the second vacuum pump is located in the suction pipe. This double-compartment vacuum cream jar has a transparent body, and the inner and outer annular chambers are respectively filled with two components of the cream. During use, the first piston slides upward and the second piston slides downward, so that the colors of the internal cream components can be superimposed and a unique visual effect can be presented during use due to the amount of internal cream used. Moreover, since the opening positions of the outer and inner annular chambers are different and they are sealed separately, accidental mixing of the two components during filling can be effectively avoided.

With this structure, two components can be pumped out at the same time by extrusion of the extrusion cover, and the two components do not meet in the discharge pipe during the pumping process, and are mixed only when the user uses it, thereby avoiding the two components meeting in the discharge pipe, resulting in a decrease in the shelf life of the mixed cream components in the discharge pipe due to long-term non-use.

[0007] In the above technical solution, preferably, a positioning bracket is provided at the place where the extrusion cover is connected to the first discharge pipe, a plurality of the first discharge holes are arranged around the center of the positioning bracket, a positioning hole is provided at the center of the positioning bracket, a first elastic sealing member is clamped in the positioning hole, and the first elastic sealing member elastically seals the plurality of the first discharge holes. This structure can elastically seal the first discharge hole to prevent the two components from mixing and prevent the components in the first discharge pipe from contacting the air.

[0008] In the above technical solution, preferably, the side wall of the second discharge hole extends inwardly with a clamping protrusion, and the clamping protrusion is clamped with a second elastic sealing member, and the second elastic sealing member elastically seals the second discharge hole. The use of this structure can elastically seal the second discharge hole to prevent the two components from mixing and prevent the components in the second discharge pipe from contacting the air.

[0009] In the above technical solution, preferably, a first vacuum pump is provided on both sides of the extrusion cover opposite to the second vacuum pump, and the suction ports of the two first vacuum pumps are both located in the outer annular bin. This structure makes the forces on both sides of the extrusion cover more balanced when the extrusion cover is pressed, and also has the function of setting the mixing ratio of the two components.

[0010] In the above technical solution, preferably, the extrusion cover includes a head cap and a conduit member, and the conduit member is clamped in the extrusion cover to form the first discharge pipe and the second discharge pipe.

The shoulder sleeve can improve the aesthetics, and the outer annular bin can be conveniently sealed by the vacuum pump positioning seat.

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

[0013] In the above technical solution, preferably, the bottom of the transparent can body is clamped with a base, which not only serves as a decoration but also protects the inner bin cover to prevent accidental damage to the inner bin cover.

[0014] The filling method of the double-compartment vacuum cream jar comprises the following steps: 1) placing the transparent jar body upright, and injecting the first component of the cream into the opening at the top of the outer annular jar; 2) covering the jar cover assembly on the transparent jar body to seal the outer annular jar; 3) inverting the transparent jar body that has covered the outer annular jar, and injecting the second component of the cream into the opening at the bottom of the inner annular jar; 4) placing the inner jar cover made of aluminum foil on the inner annular jar and pressing the bottom support; 5) sealing the inner annular jar by electromagnetic induction aluminum foil sealing equipment. The filling method is used to fill the components in the outer annular jar and the inner annular jar separately and seal them separately, which can effectively avoid accidental mixing of the two components during filling.

[0015] Compared with the prior art, the present invention has the following beneficial effects: since the double-chamber vacuum cream jar has a transparent body, and the inner annular chamber and the outer annular chamber are respectively filled with two components of the cream, during use, the first piston slides upward and the second piston slides downward, so that the colors of the internal cream components can be superimposed and a unique visual effect can be presented during use due to the amount of internal cream used; not only that, since the opening positions of the outer annular chamber and the inner annular chamber are different and they are sealed separately, accidental mixing of the two components during filling can be effectively avoided.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 9A double-compartment vacuum cream jar comprises a jar body assembly 1 and a jar cover assembly 2, the jar body assembly 1 comprises a transparent jar body 3 and an inner jar cover 4, the transparent jar body 3 is provided with an outer annular jar 5 with an opening at the top and an inner annular jar 6 with an opening at the bottom, the transparent jar body 3 is provided with a suction pipe 7 with an opening at the top and a bottom connected to the inner annular jar 6, the bottom of the inner annular jar 6 is sealed by the inner jar cover 4, the top of the outer annular jar 5 is sealed by the jar body assembly 1, air holes 8 are provided at the top of the inner annular jar 6 and the bottom of the outer annular jar 5, a first piston 9 sliding from bottom to top is provided in the outer annular jar 5, a second piston 10 sliding from top to bottom is provided in the inner annular jar 6, the jar cover assembly 2 is provided with a first vacuum pump 11 and a second vacuum pump 12, the suction port of the first vacuum pump 11 is located in the outer annular jar 5, and the suction port of the second vacuum pump 12 is located in the suction pipe 7. This double-chamber vacuum cream jar has a transparent body, and the inner annular chamber 6 and the outer annular chamber 5 are respectively filled with two components of the cream. During use, the first piston 9 slides upward and the second piston 10 slides downward, so that the colors of the internal cream components can be superimposed and a unique visual effect can be presented during use due to the amount of internal cream used. Moreover, since the opening positions of the outer annular chamber 5 and the inner annular chamber 6 are different and are sealed separately, accidental mixing of the two components during filling can be effectively avoided.

[0026] This unique visual effect depends on the color of the components of the cream, including the components of the cream may be transparent, translucent or opaque. During the use of the cream, the first piston 9 slides upward so that the bottom of the inner annular chamber 6 gradually becomes transparent, and the range of the transparent part gradually increases. During the downward sliding of the second piston 10, the top of the outer annular chamber 5 gradually becomes transparent, and the range of the transparent part gradually increases, thereby presenting a unique visual effect of change during use.

[0027] The inner bin cover 4 is made of aluminum foil. During filling, the inner bin cover 4 made of this material can conveniently seal the inner annular bin 6 through an electromagnetic induction aluminum foil sealing device.

[0028] In this embodiment, in order to reduce the space inside the suction tube 7 so that the second vacuum pump 12 can smoothly absorb the cream components, a filling tube is also provided inside the suction tube 7, the bottom of which is connected to the inner annular bin 6 and the top of which is connected to the suction port of the second vacuum pump 12.

[0029] In this embodiment, the can cover assembly 2 includes an extrusion cover 13, the tops of the first vacuum pump 11 and the second vacuum pump 12 are connected to the extrusion cover 13, the extrusion cover 13 is provided with a first discharge pipe 14 connected to the discharge port of the first vacuum pump 11 and a second discharge pipe 15 connected to the discharge port of the second vacuum pump 12, and the top of the extrusion cover 13 is provided with a first discharge hole 16 connected to the first discharge pipe 14 and a second discharge hole 17 connected to the second discharge pipe 15. With this structure, two components can be pumped out at the same time by extrusion of the extrusion cover 13, and the two components do not meet in the discharge pipe during the pumping process, and are mixed only when the user uses it, thereby avoiding the two components meeting in the discharge pipe, resulting in a decrease in the shelf life of the mixed cream components in the discharge pipe due to long-term non-use.

[0030] In this embodiment, a positioning bracket 18 is provided at the place where the extrusion cover 13 is connected to the first discharge pipe 14, and a plurality of first discharge holes 16 are arranged around the center of the positioning bracket 18. A positioning hole 19 is provided at the center of the positioning bracket 18. A first elastic sealing member 20 is clamped in 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 to prevent the two components from mixing and prevent the components in the first discharge pipe 14 from contacting the air.

[0031] In this embodiment, a clamping protrusion 21 extends inwardly from the side wall of the second discharge hole 17, and a second elastic sealing member 22 is clamped in the clamping protrusion 21. The second elastic sealing member 22 elastically seals the second discharge hole 17. This structure can elastically seal the second discharge hole 17 to prevent the two components from mixing and prevent the components in the second discharge pipe 15 from contacting the air.

[0032] In this embodiment, the first elastic sealing member 20 and the second elastic sealing member 22 are elastic members made of silicone.

[0033] In this embodiment, a first vacuum pump 11 is disposed on both sides of the extrusion cover 13 opposite to the second vacuum pump 12, and the suction ports of the two first vacuum pumps 11 are both located in the outer annular bin 5. This structure allows the forces on both sides of the extrusion cover 13 to be relatively balanced when the extrusion cover 13 is pressed, and also serves to set the mixing ratio of the two components.

[0034] In this embodiment, the extrusion cover 13 includes a head cap 23 and a conduit member 24, and the conduit member 24 is clamped in the extrusion cover 13 to form a first discharge pipe 14 and a second discharge pipe 15. The head cap 23 and the conduit member 24 are both made of PP material. The use of this structure facilitates the processing and formation of the first discharge pipe 14 and the second discharge pipe 15 on the extrusion cover 13.

[0035] In this embodiment, the can cover assembly 2 includes a shoulder sleeve 25 that is clamped with the transparent can body 3, and a vacuum pump positioning seat 26 is sandwiched between the shoulder sleeve 25 and the transparent can body 3.

[0037] In this embodiment, a bottom bracket 27 is clamped at the bottom of the transparent tank body 3, and the bottom bracket 27 is made of ABS material. The bottom bracket 27 plays a decorative role on the one hand, and can protect the inner bin cover 4 on the other hand to prevent the inner bin cover 4 from being accidentally damaged.

[0038] The filling method of the double-chamber vacuum cream jar comprises the following steps: 1) placing the transparent jar body 3 upright, and injecting the first component of the cream into the opening at the top of the outer annular jar 5; 2) covering the jar cover assembly 2 on the transparent jar body 3 to seal the outer annular jar 5; 3) inverting the transparent jar body 3 with the outer annular jar 5 covered, and injecting the second component of the cream into the opening at the bottom of the inner annular jar 6; 4) placing the inner jar cover 4 made of aluminum foil on the inner annular jar 6 and pressing the bottom support 27; 5) sealing the inner annular jar 6 by electromagnetic induction aluminum foil sealing equipment. The filling method is used to fill the components in the outer annular jar 5 and the inner annular jar 6 respectively and seal them separately, which can effectively avoid accidental mixing of the two components during filling.

[0039] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
