Description

Technical Field

[0001] This utility model relates to packaging boxes, and more particularly to a portable decorative product packaging box. Background Technology

[0002] Hair clay, as a paste or clay-like hair styling product, typically contains water, glycerin, or volatile solvents in its formula to ensure styling effects and a pleasant feel on the skin. Therefore, the airtightness of the packaging container is crucial to the product's shelf life and user experience. If the packaging is not properly sealed, the water or solvents in the hair clay will easily evaporate during storage, causing the clay to dry, harden, and crack. This not only affects its usability but also renders it ineffective for styling, leading to product failure.

[0003] In related technologies, packaging boxes for such paste-like products generally use a screw-on lid, requiring the lid to be twisted open. While this structure provides good sealing, it is extremely inconvenient to use. Especially after applying the paste to the fingers, it becomes difficult to close the lid again. Furthermore, different types and dosages of the product require different packaging boxes, which is costly and inconvenient. Summary of the Invention

[0026] The portable decorative item packaging box of this utility model is described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 13 As shown, the portable styling product packaging box provided according to the embodiments of this utility model is particularly suitable for containing volatile or easily oxidized paste-like or mud-like materials such as hair clay. The packaging box includes a bottom shell 10, a top cover 20, a replaceable inner liner 30, and a magnetic suction component.

[0028] Specifically, the top of the bottom shell 10 has an opening, and the interior of the bottom shell 10 has an inner cavity for accommodating a replaceable inner liner 30. The replaceable inner liner 30 is detachably disposed within the bottom shell 10 for holding decorative items, and the replaceable inner liner 30 can be inserted into the bottom shell 10 through the opening. The top of the replaceable inner liner 30 has an opening through which decorative items can be added to or removed from the replaceable inner liner 30.

[0029] The cover 20 is disposed on the bottom shell 10 and is pivotable between an open position and a closed position. Exemplarily, the rear edge of the cover 20 is pivotally connected to the rear edge of the bottom shell 10 via a hinge structure. When the cover 20 is in the open position, the opening of the replaceable inner liner 30 is exposed, facilitating user access to the decorative item; when the cover 20 is in the closed position, the cover 20 covers the opening of the bottom shell 10, sealing the replaceable inner liner 30. To achieve a seal, the cover 20 is provided with an elastic seal 203. This elastic seal 203 is made of materials such as silicone, thermoplastic elastomer (TPE), or flexible rubber, and is circumferentially arranged along a path corresponding to the edge of the opening of the replaceable inner liner 30 or the edge of the opening of the bottom shell 10.

[0030] The magnetic traction assembly includes a first magnetic traction element 40 and a second magnetic traction element 41. One of the first magnetic traction element 40 and the second magnetic traction element 41 is disposed on the bottom shell 10, and the other of the first magnetic traction element 40 and the second magnetic traction element 41 is disposed on the face cover 20. Exemplarily, the first magnetic traction element 40 can be fixed to the front edge of the bottom shell 10 near the opening (i.e., the side opposite the hinge structure), while the second magnetic traction element 41 is correspondingly disposed on the inner side of the front edge of the face cover 20 to ensure that when the face cover 20 is in the closed position, the first magnetic traction element 40 and the second magnetic traction element 41 can be precisely aligned and attract each other. One of the first magnetic traction element 40 and the second magnetic traction element 41 can be a permanent magnet (such as a neodymium iron boron magnet), and the other can also be a permanent magnet (opposite poles attract) or a magnetically conductive material (such as a ferromagnetic metal sheet).

[0031] When the cover 20 is in the closed position, the first magnetic member 40 and the second magnetic member 41 attract each other, causing the cover 20 to cover the opening. The elastic sealing member 203 seals against the edge of the replaceable inner liner 30 surrounding the opening, directly sealing the replaceable inner liner 30. Alternatively, the elastic sealing member 203 seals against the edge of the bottom shell 10 surrounding the opening, sealing the bottom shell 10, while the replaceable inner liner 30 is inside the bottom shell 10, thus achieving an indirect seal for the replaceable inner liner 30, allowing the decorative items inside the replaceable inner liner 30 to be sealed and preserved.

[0032] According to the portable styling product packaging box provided in this embodiment of the utility model, the cover 20 and the bottom shell 10 are pivotally connected. After the user dips the product in the packaging, they only need to close the cover 20, and the magnetic component will automatically adhere to the cover and provide a stable closing force, ensuring that the cover 20 is reliably closed. The operation is extremely simple. At the same time, the closing force generated by the magnetic attraction can make the elastic sealing element on the cover 20 tightly press against the opening edge of the replaceable inner liner 30 (or the bottom shell 10), achieving good airtightness. In addition, different sizes of replaceable inner liners or combinations of inner liners can be selected according to the needs of different scenarios, thereby facilitating the storage and management of different styling products and different dosages, improving the flexibility and convenience of use, and meeting the personalized needs of users.

[0033] Reference Figures 1 to 6 As shown, in one embodiment of this utility model, the top of the replaceable inner liner 30 has a first sealing edge 301 that surrounds the opening and protrudes upward, and the elastic seal 203 has a first annular sealing ring 2032. When the cover 20 is in the closed position, the first annular sealing ring 2032 surrounds and fits against the outside or inside of the first sealing edge 301.

[0034] In this embodiment, there is one replaceable inner liner 30. The size of the replaceable inner liner 30 is adapted to the internal size of the bottom shell 10. Furthermore, by utilizing the first annular sealing ring 2032 in conjunction with the first sealing edge 301, the cover 20 can seal the opening of the replaceable inner liner 30. Specifically, when the cover 20 pivots from the open position to the closed position, the stable adsorption force provided by the magnetic component drives the cover 20 downwards, causing the first annular sealing ring 2032 to precisely and elastically engage with the first sealing edge 301. Depending on the design, there are two preferred sealing engagement methods. Firstly, the inner diameter of the first annular sealing ring 2032 is designed to be slightly smaller than or match the outer diameter of the first sealing edge 301. When the cover 20 is closed, the first annular sealing ring 2032, under elastic deformation, surrounds and tightly adheres to the outer wall of the first sealing edge 301, forming an external circumferential seal. Secondly, the outer diameter of the first annular sealing ring 2032 is designed to be slightly larger than or match the inner diameter of the first sealing edge 301. When the cover 20 is closed, the first annular sealing ring 2032 is pressed into the opening and, relying on its elastic restoring force, tightly adheres to the inner wall of the first sealing edge 301 to form an inner circumferential seal.

[0035] The sealing structure used in this embodiment is a circumferential interference fit. Compared with a simple planar press seal, it concentrates the pressure provided by the magnetic attraction component on the circumferential annular surface of the first sealing edge 301 and the first annular sealing ring 2032, thereby improving the sealing strength of the contact area, making the seal fit tighter and more reliable, and having a stronger barrier effect to prevent the escape of moisture or solvent molecules.

[0036] Reference Figures 7 to 13 As shown, in another embodiment of the present invention, the replaceable inner liner 30 includes a first inner liner 30a and a plurality of second inner liners 30b, wherein the first inner liner 30a and the plurality of second inner liners 30b are selectively installed inside the bottom shell 10.

[0037] The size of the first inner liner 30a is adapted to the internal size of the bottom shell 10, and the size of the second inner liner 30b is smaller than the size of the first inner liner 30a. When multiple second inner liners 30b are installed in the bottom shell 10, the multiple second inner liners 30b are arranged sequentially along the length direction of the bottom shell 10.

[0038] In this embodiment, the replaceable inner liner 30 has a large inner liner (i.e., "first inner liner 30a") and multiple small inner liners (i.e., "second inner liners 30b"). The user can choose to install the first inner liner 30a inside the bottom shell 10 according to actual needs, or choose to combine multiple second inner liners 30b inside the same bottom shell 10.

[0039] Specifically, the first inner liner 30a is designed as a large-capacity container. Its outline and overall dimensions are adapted to or substantially consistent with the internal space of the bottom shell 10. When the first inner liner 30a is inserted into the bottom shell 10, it occupies most or all of the internal space of the bottom shell 10. This configuration is suitable for users who need to carry a single type of styling product in large quantities, such as a full box of standard-sized hair clay or face cream. When the first inner liner 30a is placed in the bottom shell 10, its top opening corresponds to the elastic seal 203 on the cover 20, achieving a reliable seal through the magnetic attraction force of the magnetic assembly.

[0040] As an alternative, the portable styling product packaging also provides multiple second inner liner 30b. Each second inner liner 30b is significantly smaller than the first inner liner 30a; for example, its capacity can be designed to be half, one-third, or one-quarter of the capacity of the first inner liner 30a. When the inner cavity of the base shell 10 is designed as rectangular, the multiple second inner liner 30b (e.g., two) can be designed as a smaller rectangular or square structure. When the user selects this configuration, the multiple second inner liner 30b will be housed together in the inner cavity of the base shell 10, and they will be arranged closely together along the length of the base shell 10. This configuration allows each second inner liner 30b to hold different types, colors, or functions of styling products; for example, the user can simultaneously carry small amounts of hair clay, hair wax, and concentrated styling spray.

[0041] In practical applications, the first and second inner liners can be packaged together. The larger first inner liner is suitable for occasions requiring frequent and rapid consumption, such as dressing rooms and beauty salons; the smaller second inner liner is suitable for personal and household use. Two different sized first and second inner liners can also be freely combined to create unique items, better meeting individual needs. Furthermore, if two second inner liners are used, one can be used up before opening the other, thus extending their lifespan.

[0042] The modular inner liner design provided in this embodiment enhances the versatility of the packaging box. Users do not need to purchase multiple complete packaging boxes for different capacities or types of products. They only need to use the same set of bottom shell 10 and top cover 20. By simply changing the inner liner combination, they can freely switch between "large-capacity single item" and "multi-variety sample combination" methods. This high degree of flexibility and customizability not only perfectly adapts to the differentiated usage needs in different scenarios such as beauty salons and homes, facilitating the simultaneous carrying and classification management of different dosages of the same product and multiple different products, but also increases the reusability of durable components such as the bottom shell 10 and top cover 20, thereby effectively reducing the user's overall usage cost and packaging cost.

[0043] Reference Figures 7 to 13As shown, in one embodiment of this utility model, the first inner liner 30a has a first opening, and the second inner liner 30b has a second opening. The elastic sealing member 203 has a second annular sealing ring 2033 and a plurality of third annular sealing rings 2034. The number of third annular sealing rings 2034 is equal to the number of second inner liners 30b that can be inserted into the bottom shell 10.

[0044] The top of the first inner liner 30a has a second sealing edge 302 that surrounds the first opening and protrudes upward. When the first inner liner 30a is installed inside the bottom shell 10 and the cover 20 is in the closed position, the second annular sealing ring 2033 surrounds and fits against the inner side of the second sealing edge 302.

[0045] Each of the second inner liner 30b has a third sealing edge 303 that surrounds the second opening and protrudes upward. When the plurality of second inner liners 30b are installed inside the bottom shell 10 and the cover 20 is in the closed position, each of the third annular sealing rings 2034 surrounds and fits against the outside of the corresponding third sealing edge 303.

[0046] When the user selects the large-capacity configuration, the first inner liner 30a is installed inside the bottom shell 10. When the cover 20 is pivoted to the closed position, the magnetic attraction force of the magnetic assembly presses the cover 20 down. At this time, the second annular sealing ring 2033 on the cover 20 is precisely aligned with the inner side of the second sealing edge 302 and is pressed into the first opening as the cover 20 is pressed down. Under this pressure, the outer circumferential surface of the second annular sealing ring 2033 undergoes elastic deformation and fits tightly and circumferentially against the inner wall of the second sealing edge 302, thereby forming an inner circumferential seal at the opening of the first inner liner 30a.

[0047] In the configuration of multiple second inner liners 30b, the user removes the first inner liner 30a and installs multiple second inner liners 30b inside the bottom shell 10, for example, by placing them side by side along the length. When the faceplate 20 is in the closed position, the positions of multiple third annular sealing rings 2034 on the faceplate 20 correspond exactly to the third sealing edges 303 of the multiple second inner liners 30b inside the bottom shell 10. Under the action of magnetic attraction, each third annular sealing ring 2034 will be fitted over the outside of its corresponding third sealing edge 303. The inner circumferential surface of the third annular sealing ring 2034 undergoes elastic deformation and fits tightly against the outer wall of the corresponding third sealing edge 303, thereby forming a reliable circumferential seal for each second inner liner 30b.

[0048] By integrating two sealing structures with different layouts and specifications, namely a second annular sealing ring 2033 and multiple third annular sealing rings 2034, on the same elastic sealing element 203, and respectively cooperating with the second sealing edge 302 on the first inner liner 30a and the third sealing edge 303 on the second inner liner 30b, the same reliable mating seal can be provided for two different inner liner configurations using the same set of bottom shell 10 and top cover 20.

[0049] Reference Figure 8 and Figure 11 As shown, in one embodiment of the present invention, at least one spacer portion is provided at intervals along the width direction inside the second annular sealing ring 2033, and the spacer portion and a part of the second annular sealing ring 2033 are combined to form the third annular sealing ring 2034.

[0050] This embodiment achieves adaptation and reliable sealing for two different inner liner configurations with an extremely streamlined layout on a single elastic seal 203. Compared to a solution that involves molding a separate second annular sealing ring 2033 and multiple smaller sealing rings on the elastic seal 203, this integrated structure is simpler and less expensive.

[0051] Preferably, the elastic seal 203 includes an elastic gasket 2031, which is attached to the inner surface of the cover 20. The elastic gasket 2031 is preferably made of medical-grade silicone, thermoplastic elastomer, etc. The first annular sealing ring 2032, the second annular sealing ring 2033, the third annular sealing ring 2034, and the spacer are all integrally formed on the inner surface of the elastic gasket 2031.

[0052] Reference Figures 1 to 13 As shown, in one embodiment of the present invention, the top of the bottom shell 10 is provided with a shoulder sleeve 11, the shoulder sleeve 11 surrounds the edge of the opening and is snapped to the edge of the opening from top to bottom, and one of the first magnetic suction member 40 and the second magnetic suction member 41 is fastened between the shoulder sleeve 11 and the top of the bottom shell 10.

[0053] For example, a groove for accommodating the first magnetic member 40 is provided on the top surface of the bottom shell 10 near the opening. During assembly, the first magnetic member 40 is first placed in this groove. Then, the shoulder sleeve 11 is pressed down from top to bottom and snapped onto the edge of the opening of the bottom shell 10. When the shoulder sleeve 11 is snapped into place, its bottom is pressed against the first magnetic member 40 in the groove. In this way, the first magnetic member 40 is firmly secured between the shoulder sleeve 11 and the bottom surface of the groove in the bottom shell 10. This snap-fit ​​assembly method simplifies the assembly process. At the same time, the tight snap-fit ​​structure between the shoulder sleeve 11 and the bottom shell 10 ensures that the first magnetic member 40 is confined in a precise position, guaranteeing its reliable magnetic attraction effect.

[0054] Reference Figures 2 to 6 and Figures 8 to 13 As shown, in one embodiment of the present invention, the face cover 20 includes a top cover 201 and an inner cover 202. The inner cover 202 is snapped together with the top cover 201, and the other of the first magnetic member 40 and the second magnetic member 41 is secured between the inner cover 202 and the top cover 201.

[0055] For example, a groove or limiting rib for accommodating the second magnetic member 41 is provided on the inner surface of the top cover 201 near the leading edge. The second magnetic member 41 is placed in the groove, and then the inner cover 202 is pressed in and snapped onto the top cover 201. During this process, the inner cover 202 presses tightly against the second magnetic member 41, thereby firmly fixing it between the bottom surface of the groove of the inner cover 202 and the top cover 201. This embodiment utilizes the mechanical pressure during the assembly of the inner cover 202 and the top cover 201 to secure the second magnetic member 41, simplifying the assembly process and improving production efficiency.

[0056] Reference Figure 3 and Figure 5 As shown, in one embodiment of the present invention, the outer or inner side of the first sealing edge 301 is provided with a first guiding surface S301 for guiding the first annular sealing ring 2032 to an interference fit. The first guiding surface S301 can be a slope, an arc surface or other structures.

[0057] When the cover 20 is rotated from the open position to the closed position, the first guide surface S301 provides a smooth transition contact surface for the first annular sealing ring 2032 made of elastic material, so as to accurately guide it to the outside or inside of the first sealing edge 301, thereby forming an interference fit sealing state.

[0058] In this embodiment, the guiding effect of the first guiding surface S301 not only makes the user's opening and closing operation smoother and eliminates the need for deliberate alignment, but also improves the repeatability and consistency of the seal, ensuring its long-term and efficient airtight performance.

[0059] Reference Figure 7 , Figure 10 and Figure 13 As shown, in one embodiment of the present invention, the inner side of the second sealing edge 302 is provided with a second guiding surface S302 for guiding the second annular sealing ring 2033 to an interference fit, and the outer side of the third sealing edge 303 is provided with a third guiding surface S303 for guiding the third annular sealing ring 2034 to an interference fit.

[0060] When the user places the first inner liner 30a into the bottom shell 10 and closes the cover 20, the outer periphery of the second annular sealing ring 2033 will first contact the second guide surface S302. Under the adsorption force provided by the magnetic component, the second guide surface S302 plays an automatic centering and guiding role, guiding the second annular sealing ring 2033 to smoothly slide into the first opening and making its outer peripheral surface tightly fit against the inner wall of the second sealing edge 302, forming a highly reliable inner circumferential seal.

[0061] When the user selects to use a configuration with multiple second inner liners 30b and the cover 20 is closed, the inner edge of each third annular sealing ring 2034 on the cover 20 will contact the third guide surface S303 on its corresponding second inner liner 30b. The third guide surface S303 guides the third annular sealing ring 2034 to fit tightly against the outer wall of the third sealing edge 303 under gradual radial expansion, forming an independent and reliable circumferential seal for each second inner liner 30b.

[0062] In this embodiment, the second guide surface S302 and the third guide surface S303 ensure that regardless of the inner liner configuration switched by the user, the elastic seal 203 on the cover 20 can achieve precise and smooth automatic alignment and guidance with the sealing edge on the inner liner, effectively preventing problems such as seal ring roll-up, damage, or poor sealing that may occur due to installation deviations. At the same time, the opening and closing operation of the cover 20 remains smooth, improving the user experience.
