Description

Technical Field

[0001] This application relates to the field of vacuum bottle technology, specifically to a vacuum bottle with a replaceable inner bottle. Background Technology

[0002] Vacuum bottles are packaging bottles used to store cosmetics. Current vacuum bottles typically consist of a bottle body and a cap. Once the lotion inside is used up, a new one needs to be purchased. This results in some waste due to the high cost of manufacturing these vacuum bottles, negatively impacts the environment, and increases the cost of use for consumers. Patent application number 202311428340.X discloses an environmentally friendly vacuum emulsion bottle with replaceable inner core, including an inner bottle assembly (1) and an outer bottle assembly (2). The outer bottle assembly has an opening at the top, and the inner bottle assembly can be inserted into the outer bottle assembly from the opening at the top of the outer bottle assembly, and can also be removed from the outer bottle assembly from the opening at the top of the outer bottle assembly. The detachable connection structure includes an L-shaped groove (21) set in the inner wall of the outer bottle assembly (2), and a vertically arranged protruding rib (213) is provided in the L-shaped groove (21). A snap-fit ​​protrusion (101) is set in the outer wall of the inner bottle assembly (1), and a vertically arranged positioning recess (102) is provided in the middle of the snap-fit ​​protrusion (101). When the snap-fit ​​protrusion (101) enters the second connecting groove (212) and is snapped in place, the protruding rib (213) can be snapped into the positioning recess (102). The vacuum bottle requires disassembling the connecting sleeve and removing it from the outer bottle when replacing the inner bottle assembly, making bottle replacement inconvenient. Furthermore, the inner bottle is not in a vacuum state after being connected to the pump body, which poses problems of leakage and oxidation during transport. Summary of the Invention

[0026] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0027] Combination Figures 1-6 As shown, this application provides a vacuum bottle with a replaceable inner bottle, including an outer bottle 1, an inner bottle assembly, and a pump assembly. The inner bottle assembly is detachably installed inside the outer bottle 1, and the pump assembly is detachably connected to the top of the inner bottle assembly. The inner bottle assembly includes an inner bottle 2, and the outer bottle 1 is through-entered with an opening 3 at the bottom. The inner bottle 2 can pass through the outer bottle 1 and be inserted into the outer bottle 1 from the top for installation. A stop 4 is provided at the opening 3, which is folded inward. After assembly, the bottom of the inner bottle 2 abuts against the stop 4, which serves as a limiting function. The inner wall of the outer bottle 1 is provided with a first annular locking rib 5 above the stop rib 4. The bottom of the inner bottle 2 is surrounded by a flange 6. After the inner bottle 2 is inserted into the outer bottle 1, the flange 6 and the first locking rib 5 are engaged, which serves as a positioning function. By pressing the inner bottle 2 upward through the opening 3, the inner bottle 2 can be pushed through the outer bottle 1. At this time, the inner bottle 2 and the pump assembly can be removed and disassembled as a whole.

[0028] In some embodiments, such as Figure 3 , Figure 4 and Figure 6As shown, the inner bottle assembly also includes a bottom cap 7. The bottom of the inner bottle 2 is through and has a snap-fit ​​groove 8 on its inner wall. The bottom cap 7 has a second snap-fit ​​rib 9. The bottom cap 7 is inserted into the bottom of the inner bottle 2 through the second snap-fit ​​rib 9. The bottom cap 7 has symmetrical ventilation grooves 10 on both sides. The ventilation grooves 10 are connected to the inside of the inner bottle 2. The inner bottle assembly also includes a piston 11. The piston 11 is press-fitted into the inner bottle 2. The bottom cap 7 is located below the piston 11. The piston 11 keeps the inside of the inner bottle 2 under vacuum, while the ventilation grooves 10 allow the piston 11 to communicate with the outside air. As the emulsion in the inner bottle 2 is gradually used, the air pressure will push the piston 11 upward through the ventilation grooves 10, thereby gradually pushing the emulsion upward.

[0029] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the pump assembly includes a pump body 12, a connecting seat 13, and a cap 14. The cap 14 is inserted into the top of the pump body 12, and the connecting seat 13 is fitted onto the pump body 12. The connecting seat 13 has an internal thread 15. The inner bottle 2 is detachably connected to the connecting seat 13 through an external thread 16. After the inner bottle 2 and the pump assembly are removed as a whole, the inner bottle 2 can be rotated to disassemble it. The threaded connection also serves to seal the inner bottle 2 and isolate it from external air. In this embodiment, a gasket 17 is provided between the connecting seat 13 and the bottle mouth of the inner bottle 2 to provide a sealing function. The surface of the connecting seat 13 has an anti-slip part 21 to facilitate opening the connecting seat 13 and the inner bottle 2. The cap 14 has a nozzle 18, and the top of the outer bottle 1 has a corresponding clearance groove 19. The nozzle 18 is placed in the clearance groove 19, which allows the cap 14 to move freely. The outer bottle 1 has an arc-shaped pressing port 20 on the other side of the clearance groove 19, through which the cap 14 is pressed down.

[0030] In this specification, the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
