[0032] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an airtight lip gloss tube, comprising:

[0033] A tube body 1, with a mounting seat 12 provided at the top opening thereof, and a mounting groove 13 provided on the mounting seat 12;

[0034] A shoulder sleeve 2, which is sleeved on the mounting seat 12, has a tube orifice 23 at the top, and a first limiting ring 21 and a second limiting ring 22 extending from the inside to the outside at the bottom. The first limiting ring 21 and the second limiting ring 22 are respectively clamped on the inner side and the outer side of the mounting seat 12;

[0035] A sealing ring 3, which is assembled on the mounting groove 13 and makes an interference fit and seal with the mounting seat 12 and the first limiting ring 21 or / and the second limiting ring 22;

[0036] A brush rod, comprising a cap body 5 assembled on the tube orifice 23 and a rod body 6 extending from the bottom of the cap body 5. A fuzzy head 61 is assembled on the rod body 6, and the rod body 6 is inserted into the storage cavity 11 of the tube body 1;

[0037] The top cover 7 is sleeved on the cap body 5 .

[0038] A card slot 14 is provided on the outside of the mounting seat 12, and the card block on the inner side edge of the bottom side of the shoulder sleeve 2 is engaged with the card slot 14, and the sealing ring 3 is inserted into the shoulder sleeve 2 and the mounting seat 12 for interference fit assembly, which is convenient for large-capacity use, installation and other usage requirements while ensuring the sealed installation of the shoulder sleeve 2 on the tube body 1.

[0039] An external thread is provided on the outside of the pipe opening 23 , and the external thread is screwed to the internal thread 51 of the cap body 5 to ensure a tight and stable assembly of the brush rod and the shoulder sleeve 2 .

[0040] In order to further improve the stability and structural airtightness of the assembly of the brush rod and the shoulder sleeve 2, an inner plug 4 is provided between the pipe opening 23 and the cap body 5, and the limiting side edge 42 of the top of the inner plug 4 abuts against the top surface of the pipe opening 23.

[0041] A conical tube section 41 is provided at the bottom of the inner plug 4. The inner diameter of the bottom of the conical tube section 41 is between the diameter of the rod body 6 and the diameter of the bristle head 61. This design squeezes the cosmetics adsorbed on the bristle head 61 when the brush rod is removed, causing it to desorb and drip, thereby preventing the cosmetics from dripping onto the surface of the lip gloss tube or splashing out when the brush rod is pulled out, thereby ensuring neatness in use.

[0042] A plug-in 62 is provided on the top of the hair head 61 and is inserted into the slot 63 of the rod body 6 to facilitate replacement of the hair head 61, thereby achieving sufficient and stable adsorption of cosmetics and improving the convenience of using cosmetics.

[0043] The airtight lip gloss tube of this embodiment is used as follows: when using, the top cover 7 is pulled out, the cap body 5 is held and twisted to separate it from the nozzle 23, the brush rod is pulled out, and the inner plug squeezes the bristle head 61. The excess cosmetics that are not fully absorbed by the surface drip into the storage chamber 11, and then the makeup can be used; after use, the brush rod is inserted into the inner plug 4, and the internal thread 51 of the cap body 5 is screwed with the external thread of the nozzle 23 to complete the fixation of the brush rod. The top cover 7 is pressed into the cap body 5 to complete the storage. When assembling the shoulder sleeve 2, first press the sealing ring 3 tightly into the installation groove 13, then align the outer side of the first limiting ring 21 with the inner side of the sealing ring 3, and align the second limiting ring 22 with the outer side of the top of the mounting seat 12. The shoulder sleeve 2 is pressed into the mounting seat 12 to complete the high airtight assembly.

[0044] In summary, due to the adoption of the above technical solution, the airtight lip gloss tube of this embodiment has the following beneficial effects compared with the prior art:

[0045] 1. In the present utility model, the sealing ring is press-fitted into the shoulder sleeve and the mounting seat, and is clamped by the buckle position. While facilitating the use requirements such as large-capacity use and installation, it ensures the high airtight installation of the shoulder sleeve on the tube body. Compared with the lip gloss tube structure in which the conventional splicing part is welded by ultrasonic waves, the cost of this application is reduced, and the airtightness of the product is higher, and it is not easy to have problems such as leakage of the material in the bottle and fracture of the container.

[0046] 2. In order to further improve the stability of the brush rod and the shoulder sleeve assembly and the structural airtightness, an inner plug is arranged between the tube opening and the cap body, and the limiting side edge at the top of the inner plug abuts against the top surface of the tube opening. A conical tube section is arranged at the bottom of the inner plug, and the inner diameter at the bottom of the conical tube section is between the diameter of the rod body and the diameter of the bristles. This design squeezes the cosmetics adsorbed on the bristles when the brush rod is taken out, so that it desorbs and drips, avoiding dripping on the surface of the lip gloss tube or splashing out when the brush rod is pulled out, and ensuring the cleanliness of use.

[0047] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
