Description

Technical Field

[0001] The utility model relates to the technical field of lotion bottles, in particular to a simple replacement vacuum bottle. Background Art

[0002] As people's living standards improve, their demand for cosmetics is also increasing, and a wide variety of cosmetics with different packaging have appeared on the market. There are many kinds of cosmetics in bottles, and most of the cosmetic bottles in the market are disposable items. When the liquid or lotion inside is exhausted, the entire cosmetic bottle is directly discarded, which causes great waste and pollution. In order to solve the above problems, some manufacturers are also constantly developing some replaceable lotion bottles, replacing the inner bottle containing the contents, so that the outer bottle can be reused.

[0003] Among them, there are many ways to disassemble the inner bottle and the outer bottle, some of which are clamped, and some of which are threaded. For example, the Chinese utility model patent "A vacuum bottle with a replaceable inner bottle" with application number 202223056305.3 (authorization announcement number CN 218949997U) discloses such a threaded disassembly structure. However, there are certain shortcomings in the disassembly method using such threaded connection: during the replacement process of the inner bottle assembly, it cannot be guaranteed that the tightening degree of the inner bottle assembly used for replacement is in the optimal position. If the inner bottle is screwed too loose, although it will be convenient for replacement next time, the vacuum bottle may become loose during use and affect the user experience; if it is screwed too tightly, although the possibility of automatic loosening is reduced, it may cause the inner bottle to be unable to be screwed during the next disassembly and affect the replacement of the inner bottle.

[0004] For locking or separating the inner and outer bottles by snapping, reference can be made to the Chinese invention patent "An environmentally friendly vacuum lotion bottle with replaceable inner core" with application number 202311428340.X (application publication number CN 117426612A), which realizes the combination or separation of the inner bottle assembly and the outer bottle assembly by respectively providing L-shaped slots and snap-fitting ridges on the outer bottle assembly and the inner bottle assembly, and by mutual adaptation of the L-shaped slots and the snap-fitting ridges. However, there is also a disadvantage in adopting such a snap-fitting structure: the snap-fitting ridge must first be aligned with the socket of the L-shaped slot before it can be inserted into the L-shaped slot from top to bottom, and then the inner bottle assembly and the outer bottle assembly are locked with each other by rotating the inner bottle assembly or the outer bottle assembly. During the mutual calibration process of the snap-fitting ridges and the slots, the replacement process of the user is inadvertently caused considerable trouble.

[0005] Therefore, how to provide a simple replacement vacuum bottle with a more reasonable snap-fit ​​structure that can quickly snap-fit ​​the inner bottle assembly and the outer bottle assembly without the need for prior calibration of the snap-fitting parts is an urgent problem that needs to be solved by technical personnel in this field.
