Description

Technical Field

[0001] This utility model relates to the field of cosmetic storage container technology, and in particular to a high-rigidity polymer powder box based on a snap-on pressing structure. Background Technology

[0002] Powder compacts are widely used storage containers in the cosmetics industry. They are mainly used to store various powder cosmetics such as loose powder, pressed powder, and powder powder. They not only need to have the function of storing and protecting the powder inside to prevent it from getting damp or contaminated with impurities, but also need to meet the needs of portability and ease of use. They are an indispensable core category in the beauty tool system.

[0003] With the rapid development of polymer materials technology, to improve the structural stability, impact resistance, durability, and molding precision of toner cartridges, existing toner cartridges are mostly manufactured using high-rigidity polymer materials, either as a whole or in parts. Common high-rigidity polymer materials include polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), and polyoxymethylene (POM). These materials combine the advantages of high hardness, excellent impact resistance, lightweight, and easy molding. They can effectively prevent toner cartridges from deforming and being damaged by daily bumps and squeezes, ensuring the integrity of the internal powder, while also reducing the overall weight, meeting consumers' demand for portability. Therefore, they have been widely used in the toner cartridge manufacturing industry.

[0004] In terms of the opening and locking structure design of powder cartridges, existing products generally adopt a snap-locking structure to ensure reliable closure between the lid and the body. These can be mainly divided into two categories based on the unlocking method: The first is a manual unlocking snap-locking structure, which requires the user to use both hands to manually lift the lid upwards to release the snap lock, making the operation cumbersome and inconvenient. The second is a press-to-unlock snap-locking structure, designed for one-handed operation. This type of structure has a press-to-unlock button on the body or lid of the powder cartridge. The user only needs to press the button with one hand to quickly release the snap lock. Combined with the spring hinge at the hinge joint, the lid can automatically open under the spring's rebound force, greatly simplifying the operation and improving ease of use. This has become the mainstream design solution for powder cartridge opening and closing structures.

[0005] However, existing push-to-unlock buckle locking structures have significant drawbacks. During daily carrying of the powder compact, when placed in a makeup bag or backpack, other items such as cosmetics and keys can easily squeeze or touch the push-to-unlock button, accidentally triggering the unlock and causing the buckle to malfunction. Furthermore, because the lid and body are connected by a spring hinge, once the buckle is unlocked, the lid automatically pops open under the spring's force. This not only exposes the powder to the environment, making it susceptible to moisture and dust accumulation, affecting its effectiveness and hygiene, but also risks spillage and waste. Additionally, the popped-open lid can easily scratch other items in the bag, damaging the powder compact or other items, causing significant inconvenience to the user. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a high-rigidity polymer powder cartridge based on a snap-on pressing structure that can improve the carrying safety of the powder cartridge, greatly reduce the probability of accidental opening, and also take into account the convenience of opening and closing.

[0007] This utility model discloses a high-rigidity polymer powder box based on a snap-on press structure, comprising a box body, a box lid connected to the top rear side of the box body via a coil spring hinge, a storage slot provided at the top of the box body for storing cosmetic powder, and a powder puff placed on top of the cosmetic powder, and a cosmetic mirror provided at the inner end of the box lid, and further comprising:

[0008] A fixing clip is installed on the inner edge of the box cover and is located on the opposite side of the coil spring hinge. The end of the fixing clip facing the box cover is provided with a first beveled clip head.

[0009] The movable card has a sliding groove at the top edge of the box body that matches the shape of the box body edge. The outer end of the sliding groove is connected to a through hole. The bottom end of the movable card is provided with a sliding component, which is installed in the sliding groove. The top of the outer end of the movable card is provided with a second inclined card head.

[0010] Both sides of the sliding component are provided with elastic components. When the sliding component is not subjected to external force, the two elastic components limit the sliding component to the middle of the slide groove.

[0011] When the lid and body are fastened together, pressing the lid and body causes the fixed and movable clips to snap together due to their elastic deformation, resulting in a tight fit between the first and second inclined clips. At this point, the lid and body are in close contact.

[0012] Furthermore, the sliding assembly includes an arc-shaped rod and a control block. The two ends of the arc-shaped rod are connected to the two opposite sidewalls of the slide groove. The two opposite sidewalls of the control block are provided with sliding holes adapted to the arc-shaped rod. The control block slides and fits with the arc-shaped rod through the sliding holes. The bottom end of the control block slides in contact with the bottom end of the slide groove. The bottom end of the movable card is connected to the rear side of the top center of the control block.

[0013] Furthermore, it also includes an arc-shaped switch plate. The shape of the arc-shaped switch plate is adapted to the shape of the outer circumferential side wall of the box. The middle part of the arc-shaped switch plate facing the box is connected to the control block. After the control block is squeezed by the elastic component and slid to both sides under the action of external force, the arc-shaped switch plate can still cover the slide groove. The arc-shaped switch plate slides in contact with the outer circumferential side wall of the box.

[0014] Furthermore, the elastic component is configured as a spring.

[0015] Furthermore, auxiliary plates are provided at both ends of the arc-shaped switch plate, and the outer ends of the auxiliary plates are all set as arc surfaces. At the connection between the auxiliary plate and the arc-shaped switch plate, the arc surface of the auxiliary plate is aligned with the outer wall of the arc-shaped switch plate, and the other end of the arc surface of the auxiliary plate extends close to the outer circumferential side wall of the box. The inner end of the auxiliary plate is adapted to the shape of the outer circumferential side wall of the box and slides in contact.

[0016] Furthermore, the arc-shaped switch plate has several anti-slip ridges in the middle area of ​​the side facing away from the box.

[0017] Furthermore, the sidewalls of the anti-slip ribs are all designed as curved sidewalls.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Significantly improves carrying security and reduces the probability of accidental opening.

[0020] Abandoning the traditional press-to-unlock button design, it adopts a sliding unlocking buckle locking structure, which avoids the problem of the unlock button being accidentally triggered when the powder box is squeezed inside the bag. Structurally, it greatly reduces the possibility of the lid popping open on its own, ensuring the airtightness of the powder cosmetics inside and preventing them from getting damp, dusty, or leaking.

[0021] 2. Enables convenient opening and closing operation, suitable for one-handed use scenarios.

[0022] When closing, simply press the lid to lock it in place using the elastic deformation of the beveled latch. To unlock, slide the arc-shaped switch to release the latch, and the lid will automatically pop open under the action of the coil spring hinge. The entire process can be operated with one hand, simplifying the usage process and improving ease of use.

[0023] 3. Optimize structural sealing and overall aesthetics

[0024] The arc-shaped switch plate can always cover the slide groove. Combined with the fitting design of the auxiliary plate, it not only prevents dust and other impurities from entering the slide groove and affecting the normal operation of the sliding components, but also ensures the flatness and aesthetics of the outer surface of the powder box, while improving the overall sealing performance of the structure.

[0025] 4. Improves operating comfort and anti-slip performance

[0026] The anti-slip ridges on the curved switch plate increase friction during operation, preventing hand slippage. The curved sidewalls of the anti-slip ridges also prevent hand scratches. Combined with the curved shape of the switch plate and auxiliary plate, this further enhances the comfort of gripping and operation.

[0027] 5. Ensure the stability of structural operation and the reliability of resetting.

[0028] The elastic component (spring) can stably limit the sliding component in the middle of the slide groove, ensuring the stability of the latch locking state. At the same time, it can drive the sliding component to automatically reset after the unlocking operation is completed, ensuring the continuity and reliability of the structure operation.

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] like Figures 1 to 5As shown, the high-rigidity polymer powder box based on a snap-on press structure of this utility model includes a box body 1, a box cover 2 connected to the top rear side of the box body 1 by a spring hinge, a storage slot provided at the top of the box body 1 for storing cosmetic powder, and a powder puff 3 placed on the cosmetic powder, a makeup mirror 4 provided at the inner end of the box cover 2, and also includes:

[0037] The fixing clip 5 is installed on the inner edge of the box cover 2 and is located on the opposite side of the coil spring hinge. The end of the fixing clip 5 facing the box cover 2 is provided with a first inclined clip head 6.

[0038] The movable card 7 has a sliding groove 8 at the top edge of the box body 1 that matches the shape of the edge of the box body 1. The outer end of the sliding groove 8 is connected to a through hole. The bottom end of the movable card 7 is provided with a sliding component, which is installed in the sliding groove 8. The top of the outer end of the movable card 7 is provided with a second inclined card head 9.

[0039] Both sides of the sliding component are provided with elastic components 10. When the sliding component is not subjected to external force, the two elastic components 10 limit the sliding component to the middle of the slide groove 8.

[0040] When the lid 2 and the body 1 are fastened together, pressing the lid 2 and the body 1 causes the fixed clip 5 and the movable clip 7 to be tightly engaged due to their elastic deformation, so that the first inclined clip head 6 and the second inclined clip head 9 are tightly engaged. At this time, the lid 2 and the body 1 are in close contact.

[0041] In this embodiment,

[0046] Powder puff 3: Used by users to apply powder cosmetics.

[0047] Fixed clip 5: Installed on the edge of the lid 2, the first beveled clip head 6 at its end can cooperate with the second beveled clip head 9 of the movable clip 7 to achieve the locking and fastening of the lid 2 and the box body 1.

[0048] Activity card 7: Installed in the slide groove 8 of the box body 1, it is locked by the second inclined card head 9 and the fixed card 5, and can be released as the sliding component moves.

[0049] Slide 8: Provides sliding guidance for the sliding component, ensuring the stability of the displacement trajectory of the movable card 7.

[0050] Sliding component: It moves the movable card 7 to a certain position and is the core transmission component for unlocking the buckle.

[0051] Elastic component 10: Under normal conditions, it limits the sliding component to the middle of the slide groove 8 to ensure the stability of the snap-lock state. At the same time, it can drive the sliding component to reset. There are two elastic components 10, which are symmetrically arranged on both sides of the sliding component. The purpose is to allow the sliding component to slide to the left or right. At this time, it is very convenient for the user to adjust the sliding component to the left or right, which greatly improves the adaptability of the powder box switch structure.

[0052] As a preferred embodiment of the above, the sliding assembly includes an arc-shaped rod 11 and a control block 12. The two ends of the arc-shaped rod 11 are connected to the two opposite side walls of the slide groove 8. The two opposite side walls of the control block 12 are provided with sliding holes adapted to the arc-shaped rod 11. The control block 12 is slidably fitted with the arc-shaped rod 11 through the sliding holes. The bottom end of the control block 12 is in sliding contact with the bottom end of the slide groove 8.

Its shape is adapted to the box body 1 and always covers the slide groove 8, which not only ensures the flatness of the powder box appearance, but also prevents impurities from entering the slide groove 8. At the same time, it slides in contact with the side wall of the box body 1 to ensure the stability of displacement. Moreover, the arc-shaped switch plate 13, the box body 1 and the box cover 2 are all made of high-rigidity polymer materials, such as PC, ABS, POM, etc., which have excellent impact resistance and structural stability, can resist deformation and damage caused by daily bumps and squeezing, and maintain the characteristics of lightweight, which meets the use requirements of portable travel and extends the service life of the powder box.

[0060] As a preferred embodiment of the above embodiments, the elastic component 10 is configured as a spring;

[0061] In this embodiment,

[0062] Spring: As the specific carrier of elastic component 10, it uses its own elastic deformation to realize the limiting and resetting of sliding component. It has the advantages of simple structure, stable elasticity and low cost, and can maintain the working state of sliding component stably for a long time.

[0063] As a preferred embodiment of the above embodiment, auxiliary plates 14 are provided at both the left and right ends of the arc-shaped switch plate 13. The outer ends of the auxiliary plates 14 are all set as arc surfaces. At the connection between the auxiliary plates 14 and the arc-shaped switch plate 13, the arc surface of the auxiliary plates 14 is aligned with the outer side wall of the arc-shaped switch plate 13. The other end of the arc surface of the auxiliary plates 14 extends close to the outer circumferential side wall of the box body 1. The inner end of the auxiliary plates 14 is adapted to the shape of the outer circumferential side wall of the box body 1 and slides in contact.

[0064] In this embodiment,

[0065] Auxiliary plate 14: The curved design at both ends is adapted to the side wall of the box body 1, which not only improves the overall integrity and aesthetics of the outer surface of the powder box, but also further prevents dust from entering. At the same time, the auxiliary curved switch plate 13 maintains smooth sliding and prevents it from tilting during displacement.

[0066] The auxiliary plate 14 has an arc surface: it is aligned with the side wall of the arc-shaped switch plate 13 to ensure the flatness of the outer surface. At the same time, it extends close to the side wall of the box body 1, which improves the fit and sealing of the structure. The arc surface design reduces the discomfort of pressing the edge of the auxiliary plate 14 by hand, and at the same time avoids the circumferential compression of the arc-shaped switch plate 13 by other items when the powder box is carried, reducing the probability of the arc-shaped switch plate 13 being squeezed and displaced.

[0067] As a preferred embodiment of the above, the arc-shaped switch plate 13 is provided with a plurality of anti-slip ridges 15 in the middle region of the side facing away from the box body 1.

[0068] In this embodiment,

[0069] Anti-slip ridge 15: Set on the outer surface of the arc-shaped switch plate 13, it increases the friction between the hand and the switch plate, prevents slippage during sliding operation, and improves the smoothness and stability of unlocking operation.

[0070] As a preferred embodiment of the above, the sidewalls of the anti-slip ribs 15 are all configured as arc-shaped sidewalls;

[0071] In this embodiment,

[0072] Anti-slip rib 15 curved sidewall: The sidewall of the anti-slip rib 15 is made curved to avoid the discomfort caused to the hand by sharp edges and corners, improve the comfort of the user during operation, and maintain the roundness of the overall structure. The curved sidewall also reduces the probability of the curved switch plate 13 being squeezed by other objects and causing circumferential displacement.

[0073] The working principle of this utility model is as follows:

[0074] When the powder box of this utility model is closed and locked, the user only needs to press the lid 2. The fixed clip 5 on the side of the lid 2 and the movable clip 7 on the side of the box body 1 will undergo elastic deformation due to the force. The inclined clips of the two will press against each other to complete the locking. At this time, the sliding component is in the middle of the slide groove 8 under the action of the elastic component 10, ensuring the stable locking state of the buckle. When unlocking and opening, the user slides the arc-shaped switch plate 13. The arc-shaped switch plate 13 can be slid to the left or right. The switch plate drives the control block 12 to slide along the arc-shaped rod 11 and press the elastic component 10. The movable clip 7 connected to the control block 12 is displaced accordingly. The locking state of the second inclined clip 9 and the first inclined clip 6 is released. The lid 2 automatically pops open under the action of the spring hinge. After the unlocking operation is completed, the spring force of the elastic component 10 will drive the control block 12 and the arc-shaped switch plate 13 to return to the initial position, waiting for the next closing and locking operation. The whole process realizes the unity of safe locking and convenient unlocking.

[0075] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
