Description

Technical Field

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

[0002] In today's booming cosmetics industry, cosmetic bottles, as an indispensable packaging medium, have attracted much attention regarding their design and usage. As people's pursuit of beauty continues to increase and the cosmetics market expands, the usage of cosmetic bottles has also grown dramatically.

[0003] Traditional cosmetic bottles suffer from numerous drawbacks in design and material selection. In terms of materials, existing cosmetic bottles often combine various materials, with some components made of metal to give the product a premium feel and enhance its appeal, while others are made of plastic to meet the needs of diverse shapes and cost control. However, this mixed-material design creates significant challenges for subsequent disposal after the cosmetic contents are used.

[0004] When the contents of a cosmetic product are exhausted, the tightly bonded components made of different materials make effective separation difficult, often resulting in the entire cosmetic bottle being disposed of as a whole. This not only wastes a significant amount of resources, as many still usable materials are discarded and cannot be properly recycled, but also places a heavy burden on the environment, with large quantities of discarded cosmetic bottles accumulating, occupying considerable space, and failing to degrade naturally.

[0005] In the recycling process, the vast differences in recycling processes between metals and plastics, coupled with the difficulty of separating metal and plastic components from existing cosmetic bottles, make recycling extremely complex and inefficient. Recycling companies often need to invest significant manpower, resources, and capital to process these mixed-material cosmetic bottles, which not only increases recycling costs but also reduces the quality and reusability of recycled materials, further hindering resource recycling.

The inner bottle replacement device is provided with an annular groove that can engage with the snap-fit ​​protrusions.

[0016] In some embodiments, the inner bottle replacement package includes an inner bottle body, and the annular flange, the snap-fit ​​rib, and the arc-shaped rib are integrally disposed on the outer wall of the inner bottle body.

[0017] In some embodiments, the inner bottle replacement device includes an outer ring, and an annular groove is disposed on the outer ring; an inner connecting seat is fitted inside the outer ring, and the inner bottle body is connected to the inner connecting seat; a pump body extending into the inner bottle body is installed at the center of the inner connecting seat, the pump body is connected to a push cap, and a plastic spring is installed between the push cap and the pump body.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0020] 1) The product uses a metal outer shell and an all-plastic inner bottle refill. The inner bottle refill and the metal outer shell can be easily separated after the cosmetic is used, and the inner bottle refill can be replaced for continued use, reducing usage costs. When consumers discard cosmetic bottles, they can easily separate the metal and plastic parts, greatly reducing the difficulty of recycling. For recycling companies, this easily separable structure helps to efficiently recycle and reuse different materials, reducing the complexity and cost of handling mixed materials, which is conducive to the recycling of resources, thereby reducing the pressure on the environment and conforming to the concept of environmental protection.

[0021] 2) When it is necessary to replace the inner bottle, simply rotate the metal outer bottle to disengage the snap-fit ​​groove from the snap-fit ​​rib and the arc-shaped protrusion from the arc-shaped groove, and the inner bottle replacement can be easily removed and replaced with a new inner bottle replacement. The operation is simple and convenient, which greatly facilitates consumers and improves the product user experience.

[0022] 3) Metal outer components are highly durable and reusable. On the one hand, this effectively reduces consumer waste caused by discarding the entire bottle every time cosmetics are replaced, thus reducing the negative impact on the environment. On the other hand, for manufacturers, it reduces the repeated production of metal outer components, thereby lowering product costs and improving the product's market competitiveness. At the same time, the all-plastic inner bottle replacement design is relatively simple, low-cost, and easy to mass-produce, further optimizing the product's cost structure.

[0039] Combination Figures 1-9As shown, this utility model provides a cosmetic bottle with a replaceable inner bottle, including a plastic inner bottle replacement device 1 and a metal outer bottle 2 detachably fitted onto the outside of the inner bottle replacement device 1. The inner bottle replacement device 1 contains cosmetics, and can be replaced when the cosmetics are used up. Multiple arc-shaped grooves 101 are spaced apart along the circumferential direction on the outer circumferential wall of the inner bottle replacement device 1. The inner ends of the arc-shaped grooves 101 are provided with snap-fit ​​ribs 102, which are arranged vertically. The metal outer bottle 2 has a hollow tubular structure. Multiple arc-shaped protrusions 201, which are adapted to the arc-shaped grooves 101, are arranged annularly at the bottle mouth of the metal outer bottle 2. The number of arc-shaped protrusions 201 matches the number of arc-shaped grooves 101; in this embodiment, there are two arc-shaped protrusions 201 and two arc-shaped grooves 101. The arc-shaped protrusion 201 protrudes towards the inside of the metal outer bottle 2, and the end of the arc-shaped protrusion 201 is provided with a snap-fit ​​groove 202 that can engage with the snap-fit ​​rib 102.

[0040] This structure allows the arc-shaped protrusion 201 to enter the arc-shaped groove 101 by rotating the outer metal bottle 2, thereby engaging the protruding rib 102 with the engaging groove 202. When it is necessary to replace the inner bottle, simply rotate the outer metal bottle to easily remove the inner bottle and replace it with a new one. The operation is simple and convenient, greatly facilitating consumers and improving the product's user experience.

[0041] In some embodiments, such as Figures 4 to 7 As shown, a limiting protrusion 203 is provided on one side of the snap-fit ​​groove 202. The limiting protrusion 203, the arc-shaped protrusion 201, and the metal outer bottle 2 are an integral structure. Rotating the metal outer bottle 2 allows the limiting protrusion 203 to pass over the snap-fit ​​rib 102, thereby allowing the snap-fit ​​rib 102 to engage or disengage from the snap-fit ​​groove 202. Inclined guide walls are provided on both sides of the snap-fit ​​rib 102 to facilitate the limiting protrusion 203 passing over it. This structure, with the added limiting protrusion 203, prevents the metal outer bottle 2 from rotating during use, avoiding the snap-fit ​​rib 102 from disengaging from the snap-fit ​​groove 202, ensuring connection stability; furthermore, the use of the limiting protrusion does not affect the rotation and disassembly function of the metal outer bottle 2.

[0042] In some embodiments, such as Figure 7 and Figure 8 As shown, an annular flange 103 is provided on the outer circumferential wall of the inner bottle replacement device 1. Multiple arc-shaped ribs 104 are provided at an annular interval on the lower side of the annular flange 103. There are two arc-shaped ribs 104. One end of each arc-shaped rib 104 is connected to the annular flange 103 via a snap-fit ​​rib 102. The arc-shaped ribs 104, snap-fit ​​ribs 102, and annular flange 103 form an arc-shaped groove 101. An insertion notch 204 is formed between two adjacent arc-shaped protrusions 201, allowing the arc-shaped ribs 104 to be inserted into the metal outer bottle 2 through the insertion notch 204.

[0043] When replacing the inner bottle replacement assembly 1, fit the metal outer bottle 2 onto the inner bottle replacement assembly 1, align the arc-shaped protrusion 104 with the insertion notch 204 and insert it into the metal outer bottle 2. Then rotate the metal outer bottle 2, causing the arc-shaped protrusion 201 to enter the arc-shaped groove 101 until the limiting protrusion 203 passes over the snap-fit ​​protrusion 102, at which point the snap-fit ​​protrusion 102 engages with the snap-fit ​​groove 202, thus completing the assembly. When it is necessary to disassemble the inner bottle replacement assembly 1, rotate the metal outer bottle 2 in the opposite direction, causing the limiting protrusion 203 to pass over the snap-fit ​​protrusion 102, and the snap-fit ​​protrusion 102 to disengage from the snap-fit ​​groove 202 until the arc-shaped protrusion 201 completely disengages from the arc-shaped groove 101. At this point, the arc-shaped protrusion 104 aligns with the insertion notch 204, and then pull out the inner bottle replacement assembly 1. Disassembly only requires rotating the metal outer bottle 2, making the operation simple and convenient for users.

[0044] In some embodiments, such as Figure 8 As shown, the outer end of the arc-shaped groove 101 is provided with a flared inlet 105 with a larger outer diameter and a smaller inner diameter. The flared inlet 105 facilitates the entry of the arc-shaped protrusion 201 into the arc-shaped groove 101. Multiple vertical protrusions 106 are spaced apart along the extension direction of the arc-shaped groove 101. The outer wall of the vertical protrusions 106 is a circular arc surface, facilitating the passage of the limiting protrusion 203. Through the cooperation of the vertical protrusions 106 and the limiting protrusion 203, the rotational feel of the metal outer bottle 2 is enhanced, resulting in a better user experience.

[0045] In some embodiments, such as Figures 1 to 3 as well as Figure 7 As shown, a metal bottom cap 3 is fitted onto the bottom of the outer metal bottle 2. Multiple side ribs 107 are spaced annularly at the lower end of the outer circumferential wall of the inner bottle replacement assembly 1. The metal bottom cap 3 is fitted onto the outside of the inner bottle replacement assembly 1 and is press-fitted to it via the side ribs 107. This structure, with the addition of the metal bottom cap 3, secures the inner bottle replacement assembly 1 after assembly, preventing it from shaking. When disassembling the outer metal bottle 2, the metal bottom cap 3 must be removed first; it can be pulled out directly.

[0046] In some embodiments, such as Figures 1 to 3 as well as Figure 9 As shown, the upper end of the inner bottle replacement device 1 is fitted with a metal dust cover 4. Multiple snap-fit ​​protrusions 401 are spaced circumferentially along the inner wall of the metal dust cover 4. The inner bottle replacement device 1 has an annular groove 108 that engages with the snap-fit ​​protrusions 401. The metal dust cover 4 can be removed by simply pulling it off. The outer metal bottle 2, the bottom metal cap 3, and the dust cover 4 can all be made of aluminum.

[0047] This replaceable cosmetic bottle features a metal outer casing (including a metal outer bottle 2, a metal bottom cap 3, and a metal dust cap 4) and an all-plastic inner bottle replacement pack. The inner bottle replacement pack and the metal outer casing can be easily separated after use, allowing for continued use of the replacement pack and reducing operating costs. Consumers can easily separate the metal and plastic parts when discarding the cosmetic bottle, significantly reducing the difficulty of recycling. For recycling companies, this easily separable structure facilitates efficient recycling and reuse of different materials, reducing the complexity and cost of handling mixed materials, promoting resource recycling, and thus alleviating environmental pressure, aligning with environmental protection principles.

[0048] In addition, the metal outer casing is highly durable and reusable. On the one hand, it effectively reduces consumer waste caused by discarding the entire bottle every time cosmetics are replaced, thus reducing the negative impact on the environment. On the other hand, for manufacturers, it reduces the repeated production of metal outer casings, thereby lowering product costs and improving the product's market competitiveness. At the same time, the all-plastic inner bottle replacement design is relatively simple, low-cost, and easy to mass-produce, further optimizing the product's cost structure.

[0049] In some embodiments, such as Figure 7 and Figure 8 As shown, the inner bottle replacement device 1 includes an inner bottle body 11, an annular flange 103, a snap-fit ​​rib 102, an arc-shaped rib 104, and a side rib 107 integrally disposed on the outer wall of the inner bottle body 11.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner bottle replacement device 1 includes an outer ring 12, with an annular groove 108 disposed on the outer ring 12; an inner connecting seat 13 is fitted inside the outer ring 12, and the inner bottle body 11 is connected to the inner connecting seat 13; a pump body 14 extending into the inner bottle body 11 is installed at the center of the inner connecting seat 13, and a push cap 15 is connected to the pump body 14; a plastic spring 16 is installed between the push cap 15 and the pump body 14. The pump body 14 and the plastic spring 16 are both prior art and will not be described in detail in this embodiment.

[0051] 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.

[0052] 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.
