[0035] The inner wall of the outer sleeve 2 is provided with a spiral guide groove 20 in sliding cooperation with the guide column 11, and the top end of the spiral guide groove 20 extends to form a circumferential positioning groove 21.

[0036] The inner container 1 is axially positioned by the insertion of the guide column 11 into the helical guide groove 20, and is circumferentially positioned by rotating the guide column 11 into the circumferential positioning groove 21 to complete the locking assembly.

[0037] Specifically, the inner container 1 is a cylindrical structure, and the inner container 1 is provided with a cavity for storing cosmetics. The top of the inner container 1 is open, and the top outer periphery of the inner container 1 is provided with external threads. The bottle cap 3 is provided with internal threads that threadedly cooperate with the external threads. The inner container 1 and the bottle cap 3 form a first sealing interface. The bottom of the inner container 1 is provided with a radially enlarged boss 10, and at least two guide columns 11 are uniformly distributed in the circumferential direction. The guide columns 11 are integrally formed with the inner container 1. In some embodiments, in order to improve the structural strength of the guide columns 11 and the inner container 1, a ring sleeve can also be provided on the outer periphery of the inner container 1, and the guide columns 11 are arranged on the ring sleeve. The ring sleeve, the guide columns 11, and the inner container 1 are integrally formed. Under this arrangement, the material cost of the inner container 1 can be saved while ensuring the structural strength of the guide columns 11 and the inner container 1. The boss 10 is used to abut against the bottom end surface of the outer sleeve 2, and is used to limit the axial displacement of the inner container 1. The outer sleeve 2 is a hollow structure, and two helical guide grooves 20 are formed on the inner wall thereof by an injection molding process. The groove depth of the helical guide groove 20 is matched with the guide column 11, for example, the groove depth is 3mm. The top end of the helical guide groove 20 extends out of the circumferential positioning groove 21, which is parallel to the radial direction of the outer sleeve 2. The circumferential positioning groove 21 is used to accommodate and limit the guide column 11.

[0038] The assembly process of the portable cream bottle with replaceable inner container is as follows. First, the guide column 11 of the inner container 1 is aligned with the inlet of the helical guide groove 20 of the outer sleeve 2. By utilizing the gravitational inertia of the outer sleeve 2 itself, under the joint guidance of the guide column 11 and the helical guide groove 20, the bottom of the outer sleeve slides to contact the boss 10 of the inner container 1. After the boss 10 contacts the bottom end surface of the outer sleeve 2, the inner container 1 is further rotated clockwise. The guide column 11 slides into the guide positioning groove and is attached to the groove wall through friction, thereby forming a mechanical lock.

[0039] In this embodiment, the cooperation between the guide column 11 and the helical groove realizes double fixation through axial positioning and rotational locking, thereby solving the problem of easy falling of the inner container 1 of the traditional cream bottle.

[0040] Further, the circumferential positioning groove 21 is provided with a anti-back locking structure 22 for limiting the guide column 11. When the guide column 11 rotates upward along the helical guide groove 20, resistance is generated through the wave crest 22a of the anti-back locking structure 22. The arc surface of the guide portion 22b assists the guide column 11 to slide into the guide positioning groove, thereby realizing locking. In addition, the wave crest 22a can also provide locking feedback. The completion of locking is confirmed through tactile feedback (“click” sound), thereby avoiding improper assembly.

[0041] Further, the thread angle of the helical guide groove 20 is designed to be 8°-12°, which helps to balance the smoothness of operation and locking force.

[0042] In actual application, the inner container 1 may be vibrated and dropped off during logistics transportation.
