The first tube 32 of the shell assembly 30 is securely mounted around the outer surface of the second rotating tube 12 of the driving assembly 10. The second tube 33 is further securely mounted around the first tube 32. The at least one connecting protrusion 37 of the second tube 33 is inserted into the at least one notch 35 of the first tube 32 to enable the second tube 33 to engage with the first tube 32. Then, the first tube 32 co-acts with the second tube 33. The retaining pins 38 of the top seat 34 align with the connecting grooves 363 of the retaining members 36 of the first tube 32. When the retaining pins 38 align with the connecting grooves 363, the top seat 34 may be pressed downward relative to the second tube 33.
In addition, when the retaining pins 38 slide into the retaining grooves 361 near the first faces 364, the top seat 34 is rotated relative to the first tube 32. The retaining pins 38 pass through the retaining protrusions 362 and move into the retaining sections 367. When the retaining pins 38 pass through the retaining protrusions 362, the retaining protrusions 362 are pressed downward by the retaining pins 38. The deformable grooves 39 below the retaining protrusions 362 are deformed. The retaining protrusions 362 are easy to move downward. Then, the retaining pins 38 may pass through the retaining protrusions 362 smoothly. The top seat 34 is further securely mounted on the first tube 32. The body 21 of the vessel 20 is inserted through the top seat 34 and is securely mounted on the moving seat 13 of the driving assembly 10.
With reference to FIGS. 8, 9, and 10, the top seat 34 may be rotated by users. The retaining pins 38 of the top seat 34 pass through the retaining protrusions 362 and move out of the retaining sections 367. The top seat 34 may be pulled upward by users. The retaining pins 38 pass through the connecting grooves 363 and move out of the first tube 32. The second tube 33 may be pulled upward by users. The at least one connecting protrusion 37 of the second tube 33 moves upward and moves out of the at least one notch 35 of the first tube 32. It is easy to take the second tube 33 out of the first tube 32 for replacement. The aesthetic appearance of the cosmetic container is improved. In addition, the vessel 20 may be pulled out of the moving seat 13 by users for replacement.
In operation, users may hold the second tube 33 and rotate the bottom seat 31. The first tube 32, the top seat 34, and the second rotating tube 12 are fixed on the second tube 33. The first rotating tube 11 is rotated by the bottom seat 31. The guiding protrusions 131 of the moving seat 13 move along the chutes 112 of the first rotating tube 11 and move along the longitudinal grooves 122 downwardly and upwardly. The vessel 20 is moved downwardly and upwardly by the moving seat 13. The outlet 24 of the vessel 20 is retracted and hidden in the top seat 34.
Accordingly, the second tube 33 is mounted around the first tube 32. The at least one connecting protrusion 37 of the second tube 33 is inserted into the at least one notch 35 of the first tube 32, so the second tube 33 may be coactively assembled with the first tube 32 quickly and conveniently. In addition, the top seat 34 may be pressed and rotated. The retaining pins 38 of the top seat 34 pass through the connecting grooves 363 and the retaining grooves 361 of the first tube 32. The retaining pins 38 of the top seat 34 slide into the retaining sections 367 and abut the retaining protrusions 362. Since the top seat 34 is mounted on the first tube 32 securely and conveniently, the first tube 32, the second tube 33 and the top seat 34 are convenient to assemble.
In addition, the at least one connecting protrusion 37 is formed in the inner surface of the second tube 33 and is hidden in the second tube 33. When the at least one connecting protrusion 37 is inserted into the at least one notch 35, the at least one notch 35 is covered by the second tube 33, and the at least one notch 35 is not exposed out of the second tube 33. The retaining grooves 361, the deformable grooves 39 of the first tube 32, and the retaining pins 38 of the top seat 34 are covered by the second tube 33 and are not exposed out of the second tube 33, either. The aesthetic appearance of the cosmetic container is improved. Dust is difficult to accumulate on the at least one notch 35 and the retaining members 36 of the cosmetic container.
Besides, the top seat 34 and the second tube 33 are easy to take apart from the first tube 32. The vessel 20 may be pulled out of the moving seat 13 by users. It is convenient to change to another top seat 34, another second tube 33 or another vessel 20.
