Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, and in particular to a square multi-compartment cosmetic container. Background Technology

[0002] In existing technologies, most multi-compartment cosmetic containers are round and tightened with threads, with a handle pad used for additional sealing. However, the sealing performance is poor, and the contents can easily cross-contaminate, causing pollution.

[0003] Existing technologies also include square multi-compartment cosmetic containers, but the inner and outer lids are separate structures. The seal is only released after opening the outer lid, and there are multiple inner lids (e.g., two, each sealing each inner compartment). This requires multiple openings to access all the contents, making it inconvenient. Furthermore, the seal is achieved through plastic inner lids, resulting in poor sealing (requiring an aluminum foil seal to ensure a secure seal). Utility Model Content

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0038] Reference Figures 1-13 As shown, this embodiment of the utility model provides a square multi-compartment cosmetic container, comprising:

[0039] The lower cover assembly 100 includes an outer can 110 and an inner liner 120 connected inside the outer can 110; the inner liner 120 is provided with at least two square inner compartments 121 for containing cosmetics at a distance from each other.

[0040] The top cover assembly 200 includes an outer cover 210 and a middle cover connected to the bottom of the outer cover 210. The outer cover 210 is rotatably connected to the inner liner 120. In some embodiments, the outer cover 210 is rotatably connected to the outer can 110 via a pin 130. The middle cover includes a middle cover body 220 and an elastic sealing cover 230. The middle cover body 220 is connected to the outer cover 210; the elastic sealing cover 230 is connected to the bottom of the middle cover body 220; the elastic sealing cover 230 is provided with at least two sealing protrusions 231 spaced apart, the sealing protrusions 231 protruding downward from the lower surface of the elastic sealing cover 230; the sealing protrusions 231 are correspondingly arranged one-to-one with the square inner compartment 121; the sealing protrusions 231 are located in the square inner compartment 121, and the side of the sealing protrusion 231 cooperates with the inner wall of the square inner compartment 121 to achieve a first seal; the lower surface of the elastic sealing cover 230 cooperates with the upper surface of the inner liner 120 to achieve a second seal.

[0041] The locking component 300 includes a button 310 and a locking hole 320; the button 310 is slidably connected to the outer container 110, and the button 310 is provided with a locking platform 311; the locking hole 320 is provided on the outer cover 210; when the button 310 is slid to the locking position, the locking platform 311 is engaged with the locking hole 320 to achieve locking; thereby ensuring the airtightness during storage, transportation and other conditions.

[0042] Specifically, this application features a square inner compartment 121, and an elastically deformable sealing cap 230 is provided at the bottom of the middle cover body 220. The middle cover body 220 provides support for the elastic sealing cap 230. The sealing protrusion 231 of the elastic sealing cap 230 seals against the inner wall of the square inner compartment 121, and the lower surface of the elastic sealing cap 230 seals against the upper surface of the inner liner 120, thus achieving a double seal and ensuring a stronger sealing effect, guaranteeing both freshness and cleanliness. This application connects and fixes the middle cover and the outer cover 210, allowing the square inner compartment 121 to be opened and used at once. Furthermore, one elastic sealing cap 230 can seal and release multiple square inner compartments 121, increasing the convenience for consumers. This application allows the lower cover assembly 100 to be opened by sliding the button 310. Compared to conventional snap-fit ​​structures (where positional differences occur due to tolerances), this structure controls the distance through forced locking, ensuring both sealing performance and preventing interference with the seal under any transportation conditions.

[0043] Therefore, this application addresses the issue of extending the freshness of cosmetics during storage and consumer use, providing a one-stop solution for consumers and making daily care simpler and more convenient.

[0044] Furthermore, a sealing boss 122 is provided on the upper surface of the inner liner 120 near the edge of the square inner compartment 121. The sealing boss 122 protrudes upward from the upper surface of the inner liner 120; the sealing boss 122 seals with the lower surface of the elastic sealing cover 230. Specifically, this embodiment provides a sealing boss 122 so that when the elastic sealing cover 230 is pressed and contacts the inner liner 120, it directly contacts the sealing boss 122, rather than the entire upper surface of the inner liner 120, thus reducing the contact area and improving the sealing performance.

[0045] Furthermore, the top of the sealing boss 122 is provided with two upwardly protruding rings 123, and a sealing groove 124 is formed between the two rings 123. Specifically, in this embodiment, the sealing groove 124 is formed on the top of the sealing boss 122 by means of the two rings 123. When the sealing boss 122 and the lower surface of the elastic sealing cover 230 are pressed together, causing the elastic sealing cover 230 to deform and seal, the elastic sealing cover 230 is elastic and can fill the sealing groove 124 after deformation, thereby further improving the sealing performance.

[0046] Furthermore, the middle cover body 220 and the elastic sealing cap 230 are integrally molded (e.g., integrally injection molded). In some embodiments, the middle cover body 220 is made of plastic (e.g., PP material), which is safe and environmentally friendly. The elastic sealing cap 230 is made of silicone, TPE, TPU, etc., which has a certain degree of elasticity and good resilience, thus providing better sealing performance. Specifically, the middle cover body 220 and the elastic sealing cap 230 are integrally molded, which increases the overall robustness of the middle cover and avoids the instability caused by secondary assembly.

[0047] In some embodiments, the inner liner 120 is made of PP material, which is safe and environmentally friendly.

[0048] Furthermore, the top of the middle cover body 220 is provided with a grid-like reinforcing rib 221. Specifically, the reinforcing rib 221 in this embodiment can significantly improve the deformation of the middle cover when used within a certain temperature range (e.g., in summer), thereby enhancing the stability of the seal (if the middle cover deforms, it will affect the sealing performance of this application), making the product more versatile and adaptable.

[0049] Furthermore, the button 310 is equipped with a slider; the outer can 110 is equipped with a groove 111 that penetrates its wall and extends along the X direction, and the slider is slidably connected in the groove 111. Specifically, the groove 111 serves to limit and guide the sliding of the slider.

[0050] Furthermore, the locking hole 320 is an L-shaped hole located on the outer wall of the bottom of the outer cover 210. The locking hole 320 includes a locking hole body 321 and an unlocking hole position 322 communicating with the locking hole body 321. The locking hole body 321 extends in the same direction as the slide groove 111, and the unlocking hole position 322 extends downward to the lower surface of the outer cover 210. Specifically, when the outer cover 210 is placed on top of the outer can 110, the locking platform 311 is located in the unlocking hole position 322 and is flush with the locking hole body 321. The sliding button 310 causes the slider to slide in the slide groove 111, and at the same time, the locking platform 311 also slides from the unlocking hole position 322 to the locking hole body 321 (i.e., reaches the locking position) to achieve locking. When unlocking is required, the reverse sliding button 310 causes the slider to slide in the reverse direction in the slide groove 111. At this time, the locking plate 311 gradually slides from the lock hole body 321 to the unlocking hole 322 until the locking plate 311 falls completely into the top of the unlocking hole 322. Since the unlocking hole 322 is an open hole and does not restrict the locking plate 311, the outer cover 210 can be rotated upward to open.

[0051] Furthermore, the slider includes two connecting ears 312 arranged side by side on the button 310; the ends of the two connecting ears 312 facing away from each other are provided with barbs 313, the connecting ears 312 extend into the slide groove 111 and the barbs 313 are hooked at the edge of the slide groove 111. Specifically, since the two connecting ears 312 are arranged side by side, there is a gap between the two connecting ears 312, which facilitates the insertion of the slider into the slide groove 111, and then the button 310 and the outer can 110 are quickly connected by the snapping of the barbs 313 with the edge of the slide groove 111, without affecting the sliding of the slider in the slide groove 111.

[0052] Furthermore, the outer cover 210 and the middle cover body 220 are fixedly connected by a snap-fit ​​structure. The outer can 110 and the inner liner 120 are fixedly connected by a snap-fit ​​structure. In some embodiments, the snap-fit ​​structure includes a locking platform 311 and a locking groove that mates with the locking platform 311; one of the outer cover 210 and the middle cover body 220 has a locking platform 311 and the other has a locking groove. Similarly, one of the outer can 110 and the inner liner 120 has a locking platform 311 and the other has a locking groove. Adhesive can be applied to the gap between the two to further improve the reliability of the connection.

[0053] Furthermore, the outer cover 210 is provided with a flip-top handle 211. Specifically, in this embodiment, the outer cover 210 can be opened conveniently and quickly by manually flipping the flip-top handle 211.

[0054] Except for the pin 130, which is made of stainless steel, all other parts of this application are made of plastic (the elastic sealing cover 230 is made of silicone, etc.), and are manufactured by injection molding. The middle cover is made of two-color injection molding or two injection moldings as one piece.

[0055] The middle cover and inner liner 120 of this application are sealed as a single unit. Unlocking can be achieved by sliding button 310, and then opening the top cover assembly 200 (at this time, the middle cover opens together with the outer cover 210) will release the seal of multiple square inner liner 121, and the contents of multiple inner liner 121 can be used at the same time. After closing the box, sliding button 310 in the opposite direction will seal multiple square inner liner 121 at the same time, making it convenient to use.

[0056] The improved sealing performance of this application significantly increases the airtightness of wide-mouth packaging materials, thereby extending the freshness of cosmetics and their shelf life after opening.

[0057] This application features at least two square inner compartments 121 spaced apart, allowing for simultaneous access without material mixing, thus facilitating convenience and cleanliness. Both the exterior and inner compartments of this application are square, resulting in a novel design.

[0058] This application allows consumers to conveniently enjoy multiple ingredients in one box, providing a one-stop service. The ingredients can be packaged separately, eliminating concerns about mixing. Its excellent sealing performance keeps the ingredients fresh and prevents contamination from external factors. The locking and unlocking design via a sliding button 310 ensures worry-free use, even when traveling.

[0059] The outer cover 210 and the middle cover of this application are fixedly fitted together, which can greatly improve the deformation of the middle cover at various temperatures, making the product more versatile and adaptable.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
