Description

Technical Field

[0001] This utility model relates to the field of aluminum cover technology, and specifically to an aluminum cover that is easy to assemble and disassemble. Background Technology

[0002] Aluminum caps are made by extruding aluminum alloy material using a press, followed by polishing and wire drawing processes to give them a bright appearance and unique aesthetics. A plastic liner and sealing gasket are then fixed inside the formed aluminum cap. The finished product is commonly used in cosmetic containers to seal and store cosmetics. After use, the aluminum cap can be recycled. For such recyclable aluminum caps, a design that facilitates easy assembly and disassembly is necessary from the initial design stage, allowing for convenient disassembly and reassembly during assembly or recycling. Utility Model Content

[0003] The purpose of this utility model is to design an aluminum cover that is easy to disassemble and assemble, thereby solving the problem mentioned in the background art of needing to make the aluminum cover structure easy to disassemble and assemble so that the entire aluminum cover can be easily assembled and recycled.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] An easily detachable aluminum cover includes an aluminum cover and a plastic liner. The aluminum cover has a first thread, and the plastic liner has a second thread that mates with the first thread. A force groove is formed at the lower part of the plastic liner. An internal thread is formed on the inner wall of the plastic liner. The design of the first and second threads allows the aluminum cover and the plastic liner to be connected by threads, ensuring a tight and convenient connection while maintaining a simple and reasonable overall structure. Furthermore, the force groove provides a force point, facilitating the disassembly and assembly of the aluminum cover and the plastic liner, thus enabling the assembly and recycling of the aluminum cover structure.

[0006] Preferably, the first thread is concave on the outside and convex on the inside, and the second thread is concave on the inside. By designing the shapes of the first and second threads, it is ensured that the aluminum cap and the plastic liner can achieve a threaded connection.

[0007] Preferably, the aluminum cap, located at the bottom end of the first thread flush with the end of the first thread, is provided with a resistance groove, and the plastic liner is provided with a resistance protrusion adapted to the resistance groove. The resistance groove is convex, and the resistance groove and the first thread are not connected continuously. By providing a non-continuous resistance groove and resistance protrusion at the bottom end of the first thread and the second thread respectively, the tightness of the connection between the aluminum cap and the plastic liner can be further increased, ensuring that the aluminum cap will not easily become loose from the plastic liner due to rotation during use. At the same time, by setting the resistance groove to be convex, the aluminum cap only encounters the resistance of the resistance protrusion when it is installed at the bottom of the plastic liner, avoiding resistance between the two during the installation of the aluminum cap, which would cause inconvenience.

[0008] Preferably, the force grooves are arranged in two symmetrical groups. By making the force grooves symmetrical, the force application is stable and convenient.

[0009] Preferably, the lower end of the inner wall of the plastic liner is provided with 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 diameter of the sealing strip, and more than half of the sealing strip is located in the groove, so that the sealing strip can be tightly and firmly engaged in the groove, making it difficult to fall off and achieving a sealing effect.

[0010] Preferably, a cover gasket groove is provided on the top inner wall of the plastic liner, and a cover gasket is tightly fitted into the cover gasket groove. By adding a cover gasket, the cosmetic is further sealed. The design of the cover gasket 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 after use.

[0011] Preferably, the inner plastic substrate has an integrally injection-molded partition block, which is aligned and fitted with the bottom side of the aluminum cover. The partition block design can wrap and isolate the bottom of the aluminum cover, preventing users from accidentally injuring themselves by contacting it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model, through the design of the first and second threads, enables the aluminum cap and plastic liner to be tightly and conveniently connected while maintaining a simple and reasonable structure. Simultaneously, the inclusion of resistance grooves and resistance protrusions ensures that the aluminum cap and plastic liner are locked together after the threaded connection, preventing them from rotating and further enhancing the connection's strength. Finally, symmetrically arranged force grooves facilitate positioning as force points during later disassembly, allowing the aluminum cap and plastic liner to rotate and detach easily. This makes the aluminum cap structure of this application convenient for assembly and disassembly, facilitating both initial assembly and subsequent recycling. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] The embodiments of this utility model are as follows:

[0026] See Figure 1-5As shown, the easy-to-disassemble aluminum cap includes an aluminum cap 110 and a plastic liner 210. The inner wall of the plastic liner 210 is provided with an internal thread 211, which facilitates the threaded connection of the entire aluminum cap structure with the cosmetic container.

[0027] The aluminum cover 110 has a first thread 111 with an external concave and internal convex shape on its surface, and the plastic liner 210 has a second thread 213 on its outer surface that is adapted to the first thread 111. The second internal thread 213 is concave. Through the design (including shape design) of the first thread 111 and the second thread 213, the aluminum cover 110 and the plastic liner 210 are connected by a thread, which ensures a tight and convenient connection while maintaining a simple and reasonable overall structure.

[0028] The aluminum cap 110 has a convex resistance groove 112, which is located flush with the end of the first thread 111. The resistance groove 112 is discontinuously connected to the first thread 111. The plastic liner 210 has a resistance protrusion 214 that mates with the resistance groove 112. The resistance protrusion 214 is located flush with the end of the second thread 213, and is discontinuously connected to the second thread 213. This is achieved by correspondingly providing resistance grooves at the flush ends of the first thread 111 and the second thread 213. The non-continuous resistance groove 112 and resistance protrusion 214 further increase the tightness of the connection between the aluminum cover 110 and the plastic liner 210, ensuring that the aluminum cover 110 will not easily become loose from the plastic liner 210 due to rotation during use. At the same time, the resistance groove 110 is set to be convex, so that the aluminum cover 110 only encounters the resistance of the resistance protrusion 214 when it is installed at the bottom of the plastic liner 210, avoiding the resistance between the two during the installation of the aluminum cover 110, which would cause inconvenience.

[0029] The bottom of the plastic liner 210 is symmetrically provided with force grooves 215, which can be used as force points to position the aluminum cover 110 and the plastic liner 210 structure when it needs to be disassembled later, thereby facilitating the rotation and separation of the aluminum cover 110 and the plastic liner 210.

[0030] More preferably, the bottom of the plastic liner 210 is integrally injection molded with a partition 217, which is aligned and fitted with the bottom side of the aluminum cover 110 to wrap and isolate the bottom of the aluminum cover 110, preventing the user from accidentally injuring themselves by contact with it.

[0031] Meanwhile, a rubber strip groove 212 is provided at the lower end of the inner wall of the plastic liner 210, and a sealing strip 220 is tightly engaged in the rubber strip groove 212; the opening width of the rubber strip groove 212 is smaller than the maximum diameter width of the sealing strip 220, and more than half of the sealing strip 220 is located in the rubber strip groove 212, so that the sealing strip 220 can be tightly and firmly engaged in the rubber strip groove 212, and is not easy to fall off, thus achieving a sealing effect;

[0032] In a further preferred embodiment, a cover groove 216 is provided on the inner wall of the top of the plastic liner 210, and a cover gasket 230 is tightly fitted on the cover groove 216. By adding the cover gasket 230, the cosmetic is further sealed. The design of the cover groove 216 allows the cover gasket 230 to be stably placed inside the aluminum cap 110, which not only seals the product but also prevents the user from losing it or causing inconvenience in installation.

[0033] When assembly is required, first squeeze the sealing strip 220 into the strip groove 212, then cover the cover gasket 230 in the cover gasket groove 216 on the top of the plastic liner 210, and then rotate the aluminum cover 110 onto the plastic liner 210 under the action of the first thread 211 and the second thread 213 until the resistance groove 112 and the resistance protrusion 214 are fully engaged, and the bottom of the aluminum cover 110 is attached to the top of the partition 217, thus completing the assembly of the aluminum cover structure;

[0034] When disassembly is required, external auxiliary tools (including customized clamps and clamps adapted to the force groove 215 inside the aluminum cover structure) are used in conjunction with the force groove 215 to position the aluminum cover structure. Then, the aluminum cover 110 is rotated with a little force to disengage the resistance groove 112 and the resistance protrusion 214 on the aluminum cover 110. At this time, under the action of the first thread 111 and the second thread 213, the aluminum cover 110 slowly rotates and disengages from the plastic liner 210, thus realizing the disassembly of the aluminum cover structure. It is simple and convenient.
