Description

Technical Field

[0001] This utility model relates to the field of perfume storage bottle technology, specifically a perfume storage bottle with replaceable fragrance core. Background Technology

[0002] In today's perfume market, where personalization and environmental protection are increasingly valued, perfume storage bottles with replaceable fragrance cores have gained attention for meeting consumers' diverse fragrance needs and reducing packaging waste. However, existing similar products have significant structural design flaws, making it difficult to achieve a balance between high efficiency, practicality, and environmental protection.

[0003] Existing perfume storage bottles typically use plug-in or simple threaded connections. This method is not only cumbersome to operate, but also difficult to accurately position during installation, resulting in poor sealing between the inner core and the bottle body. This can easily lead to perfume leakage and evaporation, affecting the quality of the perfume and the user experience. In addition, the structural design of these storage bottles is unreasonable when fixing the inner core, resulting in poor stability. During daily use or carrying, the inner core may shake, shift, or even detach from the bottle body, posing a significant risk of use. Furthermore, the complex disassembly and assembly process may damage bottle components, further shortening the lifespan of the storage bottle and failing to meet consumers' needs for convenient, environmentally friendly, and economical use.

[0004] Therefore, it is necessary to propose a perfume storage bottle with replaceable fragrance cores. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a perfume storage bottle with replaceable fragrance cores, which has the advantages of easy positioning and disassembly, and can ensure its airtightness, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a perfume storage bottle with a replaceable fragrance core, comprising an outer bottle body: An inner bottle is provided inside the outer bottle body. The upper surface of the outer bottle body is equipped with the outer bottle mouth, and the upper surface of the inner bottle body is equipped with the inner bottle mouth. An outer connecting block is fixedly connected to the outer surface of the inner bottle opening. A hollow circular block is fixedly connected to the top center of the inner part of the outer bottle. A mating groove is opened inside the hollow circular block. The outer surface of the inner bottle opening is inserted into the interior of the hollow circular block. The outer surface of the outer connecting block is mated to the interior of the mating groove. A bottle cap is threadedly connected to the outer surface of the outer bottle opening. The lower end of the bottle cap is threadedly connected to the interior of the inner bottle opening.

[0007] Preferably, the bottom of the outer bottle body is provided with a groove, both sides of the inside of the groove are provided with side grooves, both sides of the outer bottle body are provided with sliding grooves, and both sides of the inside of the groove are slidably connected with sealing plates.

[0008] Preferably, side sliders are fixedly connected to both sides of the sealing plate, the outer surface of the side sliders is slidably connected to the inside of the side groove, and magnetic strips are installed inside the opposite sides of the two sets of sealing plates, and the magnetic strips are magnetically attracted.

[0009] Preferably, a groove is provided on the outer side of the sealing plate, and the groove on the outer bottle body and the groove on the sealing plate are connected. A through groove is provided at the bottom of the groove.

[0010] Preferably, an L-shaped connecting strip is slidably connected inside the through groove and the slide groove, a sliding limiting block is slidably connected inside the slide groove, a second magnetic block is installed inside the top of the sliding limiting block, a first magnetic block is installed inside the top of the slide groove, and the first magnetic block and the second magnetic block are magnetically attracted to each other.

[0011] Preferably, the outer bottle opening, the inner bottle opening, and the hollow circular block are located on the same central axis.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This type of perfume storage bottle with replaceable fragrance cores is assembled by first inserting the inner bottle into the outer bottle from the bottom. The inner bottle opening is then connected to the hollow circular block inside the outer bottle via an external connector. The upper end of the cap is threaded onto the outer bottle opening, and the lower end is threaded onto the inner bottle opening, thus securing the inner bottle. At this point, the two sealing plates are pushed together, and the magnetic strips at the joint of the two sealing plates magnetically attract and secure them. The lower surface of the inner bottle then aligns with the upper surface of the sealing plate. This pushes the sliding limit block upwards, and the second magnetic block at the upper end of the sliding limit block magnetically attracts the first magnetic block at the top of the slide groove, securing the sliding limit block within the slide groove. This completes the assembly of the inner bottle. To replace the inner bottle, only... The L-shaped connecting strip needs to be pushed down to slide, simultaneously causing the sliding limiting block to slide down as well. This allows the sliding limiting block to enter the groove on one side of the sealing plate. Pulling the sliding limiting block to both sides separates the two sets of sealing plates. At this point, rotate the bottle cap, remove it, and release the restriction on the inner bottle. The inner bottle can then be removed. The new fragrance core inner bottle can be reassembled in the same way. This structure effectively positions and disassembles the inner bottle with the fragrance core. The operation is simple and convenient, requiring no complicated tools, and can be completed quickly and easily. Furthermore, the outer bottle can be reused, reducing the amount of perfume bottle waste, minimizing resource waste, and saving on usage costs. At the same time, the bottle cap simultaneously connects the outer and inner bottles, ensuring their airtightness and preventing perfume leakage or evaporation. Attached Figure Description

An outer connecting block 311 is fixedly connected to the outer surface of the inner bottle mouth 310. A hollow circular block 150 is fixedly connected to the top center of the inner bottle body 1. A mating groove 151 is opened inside the hollow circular block 150. The outer surface of the inner bottle mouth 310 is inserted into the interior of the hollow circular block 150. The outer surface of the outer connecting block 311 is mated with the interior of the mating groove 151. A bottle cap 2 is threadedly connected to the outer surface of the outer bottle mouth 140. The lower end of the bottle cap 2 is threadedly connected to the interior of the inner bottle mouth 310.

[0019] The inner bottle 3 is inserted into the outer bottle 1 from the bottom. The inner bottle opening 310 is connected to the hollow circular block 150 inside the outer bottle 1 through the outer connecting block 311. The upper end of the bottle cap 2 is threaded to the outer bottle opening 140, and the lower end of the bottle cap 2 is threaded to the inner bottle opening 310 to limit and fix the inner bottle 3.

[0020] As a preferred embodiment of this utility model, a groove 110 is provided at the bottom of the outer bottle body 1. Side grooves 120 are provided on both sides of the groove 110. Sliding grooves 130 are provided on both sides of the outer bottle body 1. A sealing plate 4 is slidably connected to both sides of the groove 110. Side sliders 410 are fixedly connected to both sides of the sealing plate 4. The outer surface of the side sliders 410 is slidably connected to the interior of the side grooves 120. Magnetic strips 420 are installed inside the opposite sides of the two sets of sealing plates 4. The magnetic strips 420 magnetically attract the sealing plate 4. A groove 130 is provided on the outer side of the bottle. The groove 130 on the outer bottle body 1 and the groove 130 on the sealing plate 4 are connected.
