Description

Technical Field

[0001] This utility model relates to the field of aluminum cover technology, specifically to assembled aluminum covers. Background Technology

[0002] Aluminum caps are made by extruding aluminum alloy material through a press, followed by grinding and wire drawing processes to give them a bright appearance and unique aesthetics. Then, plastic liners and sealing gaskets are fixedly installed inside the formed aluminum caps. The finished products are often used in cosmetic containers to seal and store cosmetics.

[0003] However, in existing aluminum cap structures, the aluminum cap and plastic liner are usually fixed together using metal-specific adhesive. While this method can securely connect the aluminum cap and plastic liner, it requires applying a uniform and appropriate amount of adhesive to the outer surface of the plastic liner to ensure a strong connection while preventing adhesive overflow. Furthermore, after snapping the aluminum cap and plastic liner together, it is necessary to wait for a period of time for the adhesive to cure, which is quite cumbersome and inconvenient. Therefore, it is necessary to design an assembly-type aluminum cap to solve the above problems and improve the installation efficiency between the aluminum cap and the plastic liner. Utility Model Content

[0004] The purpose of this utility model is to design an assembled aluminum cover to solve the problem of inconvenient installation and connection between the aluminum cover and the plastic liner in the aluminum cover structure mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The assembled aluminum cap includes an aluminum cap and a plastic liner. The surface of the aluminum cap has an integrally extruded raised groove, and the surface of the plastic liner has an integrally injection-molded raised block. The raised block and the raised groove fit together seamlessly. The inner wall of the plastic liner has internal threads. Through the interlocking of the raised groove and the raised block, the aluminum cap and the plastic liner can be firmly locked together, realizing an assembled connection. This eliminates the need for traditional glue bonding, making the operation more convenient and improving the assembly efficiency of the aluminum cap to a certain extent.

[0007] Preferably, the bottom surface of the plastic liner has a groove for a sealing strip, and a sealing strip is tightly engaged in the groove. The opening width of the groove is smaller than the maximum width of the sealing strip, and more than half of the sealing strip is located within the groove. The design of the groove and the sealing strip allows the sealing strip to be engaged quickly and easily, making installation convenient and fast. The design of the groove opening width ensures a reasonable structure that securely holds the sealing strip, preventing it from falling off and achieving a sealing effect.

[0008] Preferably, the plastic inner lining has an extension block integrally injection molded on its surface, and the bottom of the aluminum cover is tightly fitted with the top of the extension block; the outer side of the extension block is flush with the outer side of the bottom of the aluminum cover. Through the design of the extension block, the bottom of the aluminum cover can be wrapped and isolated to prevent the user's hand from coming into contact with it and causing accidental injury.

[0009] Preferably, the adhesive strip slot is formed at the bottom of the extension block.

[0010] Preferably, the inner wall of the top of the plastic liner has a recessed groove, and a cover gasket is attached to the recessed groove; the top of the cover gasket is flush with the top of the plastic liner and fits flatly against the top of the inner wall of the aluminum cap. The addition of the cover gasket can further seal the cosmetic, and the design of the recessed groove allows the cover gasket to be stably placed inside the aluminum cap, sealing the product and preventing users from losing it or experiencing installation inconvenience.

[0011] Preferably, the bottom surface of the cover pad is concave with a higher outer side and a lower middle side. By designing the bottom surface of the cover pad, the cover pad can not only seal and cover the cosmetics, but also prevent the cosmetics from contacting the cover pad and remaining on the bottom surface of the cover pad to a certain extent.

[0012] Preferably, both the raised groove and the raised block are either continuous or discontinuous. By designing the continuity of the raised groove and the raised block, the connection strength between the aluminum cover and the plastic liner can be changed and adjusted. Continuous or discontinuous raised grooves and blocks can be selected as needed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model, through the design of raised grooves and raised blocks, ensures a firm connection between the aluminum cover and the plastic liner while facilitating easy installation. Combined with the design of the adhesive strip groove, it enables quick and easy installation of the sealing strip. Furthermore, the recessed groove design facilitates easy installation of the gasket and prevents it from easily falling off. Overall, this utility model allows for quick and convenient assembly of the aluminum cover structure, thus improving the efficiency of aluminum cover assembly to a certain extent.

[0015] This invention, through the design of the extension block, can wrap and isolate the bottom of the aluminum cover, preventing users from accidentally injuring themselves by contact with it.

[0016] This invention, through the design of the recessed groove and the cover pad, allows the cover pad to be stably placed inside the aluminum cap, providing a seal while preventing users from losing it or experiencing installation inconvenience. Furthermore, the design of the bottom surface of the cover pad allows it to not only seal and cover the cosmetics but also to a certain extent prevent the cosmetics from coming into contact with the cover pad and remaining on its bottom surface.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] The embodiments of this utility model are as follows:

[0032] See appendix Figure 1-8 As shown, the assembled aluminum cover includes an aluminum cover 110 and a plastic liner 210;

[0033] Among them, the aluminum cover 110 has two sets of symmetrical raised grooves 111 integrally extruded on its surface;

[0034] The plastic liner 210 has two sets of symmetrical raised strip blocks 211 integrally injection molded on its surface. The raised strip blocks 211 and the raised strip grooves 111 fit together seamlessly, making the plastic liner 210 and the aluminum cover 110 firmly connected.

[0035] Both the raised groove 111 and the raised block 211 include a continuous annular shape or an arc-shaped discontinuous shape. By designing the continuity of the raised groove 111 and the raised block 211, the connection firmness between the aluminum cover 110 and the plastic liner 210 can be changed and adjusted. The continuous raised groove 111 and the raised block 211 or the discontinuous raised groove 111 and the raised block 211 can be selected as needed.

[0036] The inner surface of the plastic liner 210 is provided with an internal thread 212, which is threaded to the top of the cosmetic container to achieve sealed storage of cosmetics.

[0037] The plastic liner 210 has a recessed groove 213 on the top inner side wall. The cover gasket 310 fits seamlessly and neatly inside the recessed groove 213, so that the cover gasket 310 can be stably placed inside the aluminum cover 110, which not only seals the cover but also prevents the user from losing it or causing inconvenience in installation.

[0038] The bottom surface of the cover pad 310 is concave with a higher outer side and a lower middle side. This allows the cover pad 310 to seal and cover the cosmetics while also preventing the cosmetics from coming into contact with the cover pad 310 and remaining on the bottom surface of the cover pad 310 to a certain extent.

[0039] The bottom of the plastic liner 210 is integrally injection molded with an extension block 215. The bottom of the aluminum cover 110 is tightly fitted with the top of the extension block 215, which can wrap and isolate the bottom of the aluminum cover to prevent users from accidentally injuring themselves by contacting it with their hands.

[0040] The bottom of the extension block 215 is provided with a rubber strip groove 214, in which a sealing rubber strip 410 is tightly engaged. At the same time, the opening width of the rubber strip groove 214 is smaller than the maximum width of the sealing rubber strip 410, and more than half of the sealing rubber strip 410 is located in the rubber strip groove 214. This makes the structure of the rubber strip groove 214 reasonable, which allows the sealing rubber strip 410 to be engaged into the rubber strip groove 214 relatively quickly, while the two are firmly connected and not easy to fall off.

[0041] When installing the aluminum cover structure, firstly, press the sealing strip 410 into the strip groove 214. Then, place the cover gasket 310 with its concave surface facing down into the recessed groove 213 at the top of the plastic liner 210. Next, put the aluminum cover 110 on top of the plastic liner 210 and press it down firmly so that the aluminum cover 110 and the plastic liner 210 are firmly connected by the engagement of the convex groove 111 and the convex block 211. At this time, the bottom surface of the aluminum cover 110 is just aligned and fitted with the top surface of the extension block 215. This completes the installation of the aluminum cover structure. The assembly method makes the overall assembly of the aluminum cover structure convenient and quick, which improves the assembly efficiency of the aluminum cover structure to a certain extent.
