[0039] Embodiment: As illustrated in Figures 1-20, a push-button cosmetic container comprises a lid assembly, a connecting rod 30, an inner sleeve 40, a central lid 50, and a cartridge assembly 60. The lid assembly is mounted on the outside of the central lid 50, and one end of the central lid 50 protrudes from the lid assembly. The central lid 50 is mounted on the outside of the inner sleeve 40, and the inner sleeve 40 is mounted on the outside of the cartridge assembly 60. The connecting rod 30 is rotatably mounted inside the lid assembly; the first end of the connecting rod 30 is connected to the central lid 50, and the second end of the connecting rod 30 is connected to the inner sleeve 40.When the central cover 50 is pushed into the cover assembly, the central cover 50 drives the first side in a synchronous movement, the second side moves in the opposite direction, thus pushing the cartridge assembly 60 out of the cover assembly through the inner sleeve 40.The cover assembly, the inner sleeve 40, the central cover 50, and the cartridge assembly 60 are arranged coaxially. The cartridge assembly 60 is inserted into the inner sleeve 40, the inner sleeve 40 is inserted into the central cover 50, and the central cover 50 is inserted into the cover assembly. The inner sleeve can only move in the axial direction of the central cover, and the central cover 50 can only move in the axial direction of the cover assembly. The inner sleeve and the central cover, as well as the central cover and the cover assembly, are all constrained in the circumferential and radial directions by a protruding rib structure. The connecting rod 30 is rotatably mounted in the middle of the cover assembly, with its two ends moving in opposite directions.Figures 1-2 show the ready-to-use state of this cosmetic container after assembly; at this point, the lower end of the central lid 50 protrudes from the lid assembly, the first side of the connecting rod 30 is connected to the central lid and this side is in the lower position, its second side is connected to the inner sleeve 40. As illustrated in Figures 7-8, when the central lid 50 is pushed into the lid assembly, the central lid. Pushing the first end of the connecting rod upwards, the second end of the connecting rod descends, thus ejecting the cartridge assembly from the cover. The user can then remove the cartridge assembly for use. Therefore, this application utilizes the connecting rod's swing-like function to eject the cartridge assembly by pushing the central cover. Since the operating and ejection ends are located at the same end, this facilitates one-handed operation. This application is convenient to use and adds to the product's appeal.

[0040] This cosmetic container also includes an elastic element 25, the elastic element 25 being installed between the inner sleeve 40 and the lid assembly. As illustrated in Figures 18-19, in another embodiment, the second end of the connecting rod is connected to the inner sleeve 40, and the elastic element 25 is in a compressed state. When the central lid 50 is pushed inward toward the lid assembly, as illustrated in [Fig. 20], the central lid pushes the first end of the connecting rod upward, the second end of the connecting rod downward, and the inner sleeve 40 and the cartridge assembly 60 move outward from the lid assembly under the action of the elastic element 25, thus causing the cartridge assembly 60 to be ejected from the lid assembly.In another embodiment, there is no elastic element between the inner sleeve and the lid assembly; the second end of the connecting rod is connected to the inner sleeve. During use, the central lid pushes the first end of the connecting rod upwards, while the second end of the connecting rod descends and pushes the inner sleeve, resulting in a synchronous movement of the cartridge assembly, thus ejecting the cartridge assembly from the lid assembly. When this application includes an elastic element between the inner sleeve and the lid assembly, the cartridge assembly can be quickly ejected from the lid assembly, thereby improving the smoothness and ease of use of this cosmetic container for the user.

[0041] In this case, the inner sleeve 40 is connected to the cover assembly. Optionally, the inner sleeve and the cover assembly are connected by limiting elements. As illustrated in [Fig. 1], the inner sleeve and the cover assembly are nested one inside the other, and the elastic element 25 is in a compressed state. During use, as illustrated in [Fig. 7], the central cover pushes the first side of the connecting rod upwards, the second side of the connecting rod downwards, and the inner sleeve 40 detaches from the cover assembly under the effect of the force. The elastic element 25 is released, and under the action of the restoring force of the elastic element, the inner sleeve 40 and the cartridge assembly 60 are ejected outwards from the cover assembly. In another In this embodiment, the inner sleeve and the lid assembly are fitted together, but there is no elastic element between the inner sleeve and the lid assembly. This means that the container has two configurations: the first configuration: when the container is in the closed position, i.e., when the cartridge assembly 60 is retracted into the lid assembly, the inner sleeve 40 is connected to the lid assembly; the second configuration: when the container is in the closed position, i.e., when the cartridge assembly 60 is retracted into the lid assembly, the inner sleeve 40 is connected to the other end of the connecting rod 30.

[0042] The cover assembly comprises an outer cover 10 and an inner cover 20 fixed together, the inner cover 20 being placed inside the outer cover 10. As illustrated in [Fig.

[14] , the lower end of the inner cover 20 extends downwards along the axis to form a projecting lug 21, the projecting lug 21 being provided with a rotation axis hole 22. The inner cover 20 is provided with a first limiting element 23 and a second limiting element 24. The connecting rod 30 is provided with a rotation axis 31, the first side being provided with a first connecting element 32, the second side being provided with a second connecting element 33. The rotation axis 31 is installed in the rotation axis hole 22, the first connecting element 32 is connected to the central cover 50, the second connecting element 33 is connected to the inner sleeve 40.The outer cover 10 is a hollow tubular structure with an opening at its lower end. The inner cover 20 is installed inside the upper end of the outer cover. The inner cover 20 has two projecting tabs 21 arranged symmetrically along the central axis. As illustrated in Figures 1-2, 9, and 14, the outer cover 10 and the inner cover 20 are secured by snap-fitting. The two projecting tabs 21 are arranged parallel to each other. The inner wall of the inner cover has a first limiting element 23 and two second limiting elements 24 arranged parallel to each other. The two second limiting elements are arranged symmetrically along the central axis of the inner cover.

[0043] As illustrated in [Fig. 15], the connecting rod 30 is provided internally with a housing groove 34, the axis of rotation 31, the first connecting element 32, and the second connecting element 33 all extending outwards in the radial direction of the connecting rod 30. The connecting rod 30 has a hollow annular structure internally, the hollow portion being the housing groove 34. The front and rear walls of the connecting rod 30 are each provided with an axis of rotation; the left wall is provided with the first connecting element 32, and the right wall is provided with the second connecting element 33. During assembly, as illustrated In [Fig.4], the two rotation axes 31 are respectively installed in the rotation axis holes 22, so that the connecting rod 30 can rotate relative to the inner cover 20. The first connecting element 32 is connected to the central cover 50; when the central cover 50 moves downwards, the first connecting element of the connecting rod 30 descends while the second connecting element ascends, according to a principle similar to that of a seesaw.

[0044] The inner sleeve 40 is provided with a third limiting element 41 and a fourth limiting element 43. The third limiting element 41 can be inserted into the second connecting element 33, and the third limiting element 41 can interlock with the first limiting element 23. The fourth limiting element 43 can interlock with the second limiting element 24. The first, second, third and fourth limiting elements can be structures such as hooks, snap points, magnetic points, etc., as long as they achieve mutual interlocking between the first limiting element and the third limiting element, as well as between the second limiting element and the fourth limiting element.

[0045] As illustrated in [Fig. 16], the inner sleeve 40 is a hollow tubular structure with an opening at the lower end, the upper surface of the inner sleeve 40 extending upwards along the axis to form a third limiting element 41 and a tubular body 42, the fourth limiting element 43 being disposed on the tubular body 42. The diameter of the tubular body 42 is smaller than that of the main body of the inner sleeve and the tubular body is disposed coaxially with the main body of the inner sleeve, the tubular body 42 is provided with two fourth limiting elements 43 disposed symmetrically along the central axis of the tubular body, the third limiting element 41 being located on one side of the tubular body.

[0046] The fourth limiting element 43 is inserted into the housing groove 34, the inner cover 20 extending along the axial direction to form a limiting sleeve 26, one end of the elastic element 25 being placed in the limiting sleeve 26, the other end of the elastic element being placed in the tubular body 42. During assembly, as illustrated in [Fig. 10], the two fourth limiting elements pass through the housing groove 34 of the connecting rod 30, as illustrated in [Fig. 2], the third limiting element 41 passes through the second connecting element 33 and this third limiting element hooks onto the first limiting element 23, thus connecting the inner sleeve to the inner cover, compressing the elastic element between the inner cover and the inner sleeve, the fourth limiting element 43 on the sleeve interior 40 and the second limiting element 24 on the inner cover serving to limit the maximum stroke of the elastic element.

[0047] As illustrated in [Fig. 17], the central cover 50 is a hollow tubular structure with openings at both the upper and lower ends, the upper end of the central cover 50 extending along the axial direction to form a connecting rod 51, the connecting rod 51 being provided with an installation slot 52 for installing the first connecting element 32. As illustrated in Figures 2 and 10-11, the first connecting element 32 of the connecting rod is inserted into the installation slot 52 of the central cover, so that the central cover can cause a synchronous movement of the first connecting element of the connecting rod, the third limiting element 41 of the inner sleeve 40 is inserted into the second connecting element 33 of the connecting rod and the third limiting element 41 hooks onto the first limiting element 23 of the inner cover,thus limiting the inner sleeve and the cartridge assembly inside the outer cover 10, while compressing the elastic element 25 between the inner cover and the inner sleeve, as illustrated in Figures 3-4, at this moment there is a certain distance between the second limiting element 24 of the inner cover and the fourth limiting element 43 of the inner sleeve, this distance being the maximum stroke of the spring; when the central cover 50 is pushed inwards into the inner cover 20, the central cover 50 drives the first connecting element 32 of the connecting rod upwards, causing the second connecting element 33 of the connecting rod to descend and giving a horizontal force to the third limiting element 41, causing the third limiting element to bend to the left and detach from the first limiting element 23, as illustrated in Figures 5-6,At this point, the constraint force on the elastic element 25 disappears, the elastic element 25 relaxes, pulling the inner sleeve and the cartridge assembly 60 downwards. The cartridge assembly is ejected from the outer cover 10, as illustrated in Figures 7-8, 12-13. At this point, the central cover is in contact with the lower end of the outer cover, the second and fourth limiting elements interlock, and the user can then remove the cartridge assembly 60 for use.

[0048] As illustrated in Figures 1-8, the cartridge assembly 60 comprises an inner cartridge portion 61, a counterweight 62, and a base 63. The inner cartridge portion 61 is rotatably installed inside the base 63, and the counterweight 62 is positioned between the inner cartridge portion 61 and the base 63. The inner cartridge portion 61 contains cosmetics such as lipstick, lip gloss, lip balm, etc. By rotating the base 63, the cosmetic product is dispensed from the inner cartridge portion for application by the user. This assembly of Cartridge 60 is a structure commonly used for lipstick-type cosmetics and will not be described in detail here.

[0049] The process of using this application includes the following steps:

[0050] Step 1: Initially, the cosmetic container is in the closed position, as illustrated in Figures 1-2, 10-11, the lower end of the central cover 50 protrudes from the outer cover 10, the first side of the connecting rod 30 is connected to the connecting rod 51 of the central cover and this side is in the lower position, the third limiting element 41 of the inner sleeve 40 is inserted into the second connecting element 33 of the connecting rod and the third limiting element 41 hooks onto the first limiting element 23 of the inner cover;

[0051] Step 2: The user pushes the central cover 50 inwards, the central cover 50 drives the first connecting element 32 of the connecting rod upwards, causing the second connecting element 33 of the connecting rod to descend and giving a horizontal force to the third limiting element 41, causing the third limiting element to bend to the left and detach from the first limiting element 23, as illustrated in Figures 5-6;

[0052] Step 3: At this moment, the constraining force on the elastic element 25 disappears, the elastic element 25 relaxes, pulling the inner sleeve and the cartridge assembly 60 downwards, causing the cartridge assembly to come out of the outer cover 10, as illustrated in Figures 7-8, 12-13. At this moment, the central cover is in contact with the lower end of the outer cover, the second limiting element 24 and the fourth limiting element 43 fit together, the user can then remove the cartridge assembly 60 for use.

[0053] It should be noted that, for ordinary technicians in the field, without departing from the idea of ​​this application, it is still possible to make various modifications and improvements, all of which fall within the scope of protection of this application.
