DETAILED DESCRIPTION OF EMBODIMENTS

The present utility model will be further described below in conjunction with the accompanying drawings and particular embodiments.


As show in FIGS. 1 to 5, a replaceable cosmetic bottle, comprising an outer bottle 1, an inner container 2 and a bottle cap 3, wherein the outer bottle 1 comprises a first threaded connection portion 11 and a second threaded connection portion 12 which are disposed on an upper portion of the outer bottle 1, with the outer diameter of the first threaded connection portion 11 being less than that of the second threaded connection portion 12, that is, a step structure is formed between the first threaded connection portion 11 and the second threaded connection portion 12.


The second threaded connection portion 12 is in threaded connection with the bottle cap 3, the inner container 2 comprises a vertical ring boss 23, the vertical ring boss 23 is in threaded connection with the first threaded connection portion 11, and the inner container 2 is fitted to the bottle cap 3 to enclose the outer bottle 1.


The outer bottle 1 is in threaded connection with the bottle cap 3 in such a specific manner that an inner annular wall of a lower portion of the bottle cap 3 is provided with a bottle cap inner screw thread 31, and an outer annular wall of the second threaded connection portion 12 is provided with a second outer screw thread 14 that is fitted in threaded connection with the bottle cap inner screw thread 31.


The inner container 2 is in threaded connection with the bottle cap 3 in such a specific manner that an inner annular wall of the vertical ring boss 23 is provided with a ring boss inner screw thread 26, and an outer annular wall of the first screw connection portion 11 is provided with a first outer screw thread 13 that is fitted in threaded connection with the ring boss inner screw thread 26. When the inner container 2 is mounted, all that is needed is to screw the inner container 2 into the outer bottle 1, which is simply and convenient for assembly and disassembly, realizing replacement of the inner container 2.


The inner container 2 further comprises a main accommodation body 21 for holding a cosmetic, a horizontal ring boss 22 formed by horizontally extending outward from an upper end of the main accommodation body 21, and a flip cap 24 integrally formed with the main accommodation body 21 for covering the main accommodation body 21, with an outer edge of the horizontal ring boss 22 vertically extending downward to form a vertical ring boss 23. The first threaded connection portion 11 extends between an upper portion of the main accommodation body 21 and the vertical ring boss 23, and the first threaded connection portion 11 vertically abuts against the horizontal ring boss 22.


The flip cap 24 is connected to one side of the horizontal ring boss 22.
