[0003] One purpose of the utility model is to provide a cosmetic jar using three-start thread to solve the problems existing in the prior art.

[0004] To achieve this purpose, the utility model adopts the following technical scheme:

[0005] A cosmetic jar using three-start thread, comprising a jar, an inner container and an upper cover, the inner container is in the inside of the jar, the upper cover covers the upper end of the jar, the inner side of the upper cover is provided with three-start internal thread, the upper end of the outside of the jar is provided with three-start external thread, the three-start external thread and the three-start internal thread form a threaded connection, and the number of turns between the three-start external thread and the three-start internal thread is one turn.

[0006] As a preferred technical scheme, the material of the upper cover is aluminum alloy, and the material of the jar is aluminum alloy.

[0007] As a preferred technical scheme, the upper end of the outside of the inner container is provided with a snap ring, the upper end of the inside of the jar is provided with a clamping groove, the snap ring is clamped in the clamping groove, and the lower end of the snap ring is arc-shaped.

[0008] As a preferred technical scheme, the upper end of the inside of the jar is provided with a mounting groove, and the upper end of the inside of the jar is pressed in the mounting groove.

[0009] The utility model has the advantages that the cosmetic jar using three-start thread can ensure that the number of turns required to open the upper cover is within one turn, which facilitates consumers to quickly open the package and use the product, effectively improves the use experience of consumers, and improves the convenience.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figs. 1-3 As shown in this embodiment, a cosmetic container using a three-pronged thread includes a container body 1, an inner liner 2, and a top cover 3. The inner liner 2 is located inside the container body 1, and the top cover 3 covers the upper end of the container body 1. The inner side of the top cover 3 is provided with a three-pronged internal thread 4, and the outer side of the upper end of the container body 1 is provided with a three-pronged external thread 5. The three-pronged external thread 5 and the three-pronged internal thread 4 form a threaded connection, and the number of rotations between the three-pronged external thread 5 and the three-pronged internal thread 4 is one revolution.

[0018] More specifically, the top cover 3 is made of aluminum alloy, the tank body 1 is made of aluminum alloy, the upper outer side of the inner liner 2 is provided with a retaining ring 6, the upper inner side of the tank body 1 is provided with a retaining groove 7, the retaining ring 6 is engaged in the retaining groove 7, the lower end of the retaining ring 6 is arc-shaped, the upper end of the inner liner 2 is flipped outward, the upper end of the tank body 1 is provided with an installation groove 8, and the upper end of the inner liner 2 is pressed into the installation groove 8.

[0019] When the product needs to be used after closing the top cover 3, it can be completely separated from the can body 1 by manually twisting it less than one turn. This allows consumers to quickly open the cosmetic packaging and use the product, effectively improving the consumer experience. The unconventional three-thread structure ensures the number of turns, and the aluminum alloy material reduces the possibility of scratches between the top cover 3 and the can body 1, extending the life of the packaging.

[0020] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
