Description

Technical Field

[0001] This utility model relates to a cosmetic packaging box, specifically an ultra-thin powder box. Background Technology

[0002] In the current cosmetic packaging industry, especially for ultra-thin powder compacts designed for powder cosmetics, several technical problems urgently need to be solved. Traditional ultra-thin powder compacts often feature right-angled edges in their inner liner design. This structure is quite inconvenient in actual use, making it difficult for users to easily remove the cosmetics from the inner liner with their fingers, thus affecting the user experience. Furthermore, powder compacts often incorporate glass mirror elements in their design to meet users' needs for touch-ups. However, due to the material properties of glass mirrors, their fragility is a significant drawback. If accidentally dropped or subjected to external impact, the mirror is easily broken, affecting not only the aesthetics of the powder compact but also causing unnecessary trouble and financial loss for users. Additionally, traditional powder compacts typically have an inner liner ring along the outer edge of the inner liner to enhance its stability and sealing. However, the existing methods for installing the inner liner ring have obvious shortcomings. Most of them simply open a groove with an upward-facing opening on the outer edge of the inner liner and insert the inner liner ring into it. This simple limiting structure lacks sufficient stability. If the user accidentally touches the inner liner ring during use, it may fall off, which seriously affects the practicality and durability of the toner cartridge.

[0003] In summary, existing toner cartridges have significant shortcomings in terms of inner container design, mirror material selection, and inner container ring installation method. There is an urgent need for a new type of ultra-thin toner cartridge to overcome these technical problems and improve the user experience. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide an ultra-thin powder box.

[0005] The technical solution of this utility model is: an ultra-thin powder box, including a base, an inner liner, an inner liner ring, an inner liner cover, and an outer cover. The inner liner is fixed inside the base, the inner liner is clipped between the inner wall of the base and the outer wall of the inner liner, the inner liner ring is clipped on the edge of the inner liner, the inner liner cover is placed on the upper end of the inner liner, and the outer cover is fixed on the upper end of the base. The inner side wall of the inner liner is an arc surface, and a PET lens is fixed on the top of the outer cover. The edge of the inner liner has an upward-facing, annular groove. A first annular protrusion is provided on the outer wall of the inner liner ring, and a second annular protrusion is provided on the inner wall of the inner liner ring. The inner wall of the groove has a first slot for the first protrusion to be inserted and a second slot for the second protrusion to be inserted.

[0006] Furthermore, the right end of the outer cover is rotatably connected to the right end of the base via a pin, and the left end of the outer cover is connected to the left end of the base via a snap-fit ​​connection.

[0007] Furthermore, the rear end of the inner liner cover is rotatably connected to the rear end of the inner liner via a pin, and the front end of the inner liner is connected to the front end of the inner liner via a snap-fit ​​connection.

[0008] Furthermore, a sealing ring is placed at the bottom of the groove, and the inner liner is pressed against the outer wall of the sealing ring.

[0009] The advantages of using the ultra-thin powder box provided by this utility model are:

[0010] The inner wall of the inner container is designed with a rounded surface, which makes it easier for users to remove cosmetics from the inner container with their fingers, avoiding the inconvenience caused by the traditional right-angle edge design, and significantly improving the comfort and convenience of use.

[0011] Replacing traditional glass mirrors with PET lenses not only maintains a good visual effect and meets users' makeup touch-up needs, but also the PET material has higher impact resistance and drop resistance, greatly reducing the risk of breakage caused by drops or external impacts. This protects the aesthetics of the powder box and avoids unnecessary trouble and economic losses for users.

[0012] The first and second convex rings on the inner liner are secured to the first and second locking grooves of the inner liner, respectively. This double-limiting structure significantly enhances the stability of the inner liner and effectively prevents it from falling off. Attached Figure Description

[0019] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0020] like Figure 1 — Figure 5 As shown, an ultra-thin powder box includes a base 1, an inner liner 2, an inner liner 3, an inner liner ring 4, an inner liner cover 5, and an outer cover 6. The inner liner 2 is fixed inside the base 1. The inner liner 3 is fitted between the inner wall of the base 1 and the outer wall of the inner liner 2. The inner liner ring 4 is fitted around the edge of the inner liner 2. The inner liner cover 5 covers the upper end of the inner liner 2. The outer cover 6 is fixed to the upper end of the base 1. The inner wall of the inner liner 2 is an arc surface 21. A PET lens 7 is fixed to the top of the outer cover 6. The edge of the inner liner 2 has an annular groove 22 with an upward opening. The outer wall of the inner liner ring 4 has a first annular protrusion 41, and the inner wall of the inner liner ring 4 has a second annular protrusion 42. The inner wall of the groove 22 has a first slot 221 for the first protrusion 41 to be inserted into and a second slot 222 for the second protrusion 42 to be inserted into.

[0021] To facilitate the connection of the outer cover 6 to the base 1, the right end of the outer cover 6 is rotatably connected to the right end of the base 1 via a pin 8, and the left end of the outer cover 6 is connected to the left end of the base 1 via a snap-fit ​​connection.

[0022] To facilitate the connection between the inner liner cover 5 and the inner liner 2, the rear end of the inner liner cover 5 is rotatably connected to the rear end of the inner liner 2 via a pin 8, and the front end of the inner liner 2 is connected to the front end of the inner liner 2 via a snap-fit ​​connection.

[0023] A sealing ring 9 is placed at the bottom of the groove, and the inner ring 4 is pressed against the outer wall of the sealing ring 9.

[0024] like Figure 4 As shown, the ultra-thin powder box provided by this utility model has an inner wall surface 21 with rounded edges 21, which allows users to more easily take out cosmetics from the inner box 2 with their fingers, avoiding the inconvenience caused by the traditional right-angle edge design, and significantly improving the comfort and convenience of use.

[0025] This utility model uses PET lenses 7 to replace traditional glass mirrors, which not only maintains a good visual effect and meets the user's makeup needs, but also the PET material has higher impact resistance and drop resistance, which greatly reduces the risk of breakage caused by drops or external impacts. This protects the aesthetics of the powder box and avoids unnecessary trouble and economic losses for users.

[0026] like Figure 5 As shown, the first protruding ring 41 and the second protruding ring 42 on the inner liner 4 of this utility model are respectively secured to the first slot 221 and the second slot 222 of the inner liner 2. This double limiting structure significantly enhances the stability of the inner liner 4 and can effectively prevent it from falling off.

[0027] Of course, the above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. The base 1, pin 8, inner liner 3, outer cover 6, and PET lens 7 of this utility model are all made of PET material, while the inner liner 2, inner liner ring 4, and inner liner cover 5 are all made of PP material. The powder box can be designed to be ultra-thin by reducing the thickness of each component. Any simple modifications and equivalent structural changes made using the description and drawings of this utility model should also be included within the patent protection scope of this utility model.
