[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 6A cream bottle with a replaceable liner comprises an outer bottle 1, wherein the upper side wall of the outer bottle 1 is provided with a through hole 1 2 and a plurality of through holes 2 3 located outside the bottle mouth of the outer bottle 1, the inner wall of the through hole 1 2 is smoothly arranged, the through holes 1 2 and the through holes 2 3 are distributed in a circular shape with equal intervals, an inner liner 4 is movably inserted inside the outer bottle 1, a flange is fixedly arranged at the bottle mouth of the inner liner 4, the flange is pressed on the bottle mouth of the outer bottle 1, a pressure ring 5 is arranged on the upper side of the flange, a limiting mechanism is arranged between the pressure ring 5 and the outer bottle 1, and the upper side wall of the pressure ring 5 is fixed A vertically upward connecting pipe 16 is fixedly provided, the outer side wall of the connecting pipe 16 is provided with a spiral tooth 17, the outer side of the connecting pipe 16 is sleeved with an end cover 8, the inner top wall of the end cover 8 is fixedly connected with a vertically downward connecting pipe 2 13, the diameter of the connecting pipe 2 13 is larger than the diameter of the connecting pipe 16, the inner side wall of the connecting pipe 2 13 is provided with a spiral tooth 2 14, the spiral tooth 2 14 is meshed with the spiral tooth 17, the inner top wall of the end cover 8 is fixedly provided with a gasket 15, and the gasket 15 matches the upper end of the connecting pipe 6.

[0022] The limiting mechanism includes a guide column 9 fixedly connected to the lower side wall of the edge pressing ring 5, the guide column 9 is slidably inserted in the through hole 2, the lower end of the guide column 9 is located at the lower side of the through hole 2, the length of the guide column 9 is greater than the depth of the inner liner 4, and a stopper 10 is fixedly provided at the lower end of the guide column 9. A spring 11 is sleeved on the guide column 9 and is located between the inner top wall of the outer bottle 1 and the stopper 10. The spring 11 presses the edge pressing ring 5 against the flange of the inner liner 4. The lower side wall of the edge pressing ring 5 is also fixedly connected with a plurality of guide columns 12 corresponding to the through holes 3. The guide columns 12 are slidably inserted in the through holes 3, and the lower ends of the guide columns 12 are flush with the lower side walls of the through holes 3.

[0023] Under the pulling force of the spring 11, the pressure ring 5 is tightly pressed against the flange of the inner liner 4, so that the inner liner 4 is squeezed and fixed to the outer bottle 1, and the guide pillars 1 9 and 12 limit the rotation of the pressure ring 5. At the same time, multiple guide pillars 12 improve the torsional strength of the pressure ring 5 on the outer bottle 1. After unscrewing the end cover 8, the cream in the inner liner 4 can be reached from the middle of the connecting tube 1 6. After tightening the end cover 8, the gasket 15 is pressed against the port of the connecting tube 6, which enhances the airtightness between the inner liner 4 and the end cover 8.

[0024] When replacing the inner liner 4, keep the end cover 8 on the connecting tube 1 6 and pull the end cover 8. The edge pressing ring 5 will simultaneously drive the guide pillar 1 9 and the guide pillar 2 12 to slide outward. As the spring 11 is continuously compressed, the guide pillar 2 12 disengages from the through hole 2 3. When the distance between the edge pressing ring 5 and the bottle mouth of the outer bottle 1 is greater than the outer body length of the inner liner 4, the edge pressing ring 5 is rotated to rotate around the guide pillar 1 9 to the outside of the outer bottle 1. At this time, the inner liner 4 is taken out and a new inner liner 4 is put in. Then the edge pressing ring 5 is rotated to align the guide pillar 2 12 with the through hole 2 3. The edge pressing ring 5 is slowly loosened. Under the action of the spring 11, the edge pressing ring 5 presses the flange of the inner liner 4 to the bottle mouth of the outer bottle 1, thereby fixing the inner liner 4 and improving the convenience of replacing the inner liner 4.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
