Description

Technical Field

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

[0002] As people's living standards improve, their demand for cosmetics is also increasing. A wide variety of cosmetics with different packaging have appeared on the market. Among them, bottled cosmetics are even more numerous, and most of the cosmetic bottles of bottled cosmetics on 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 currently developing some replaceable lotion bottles, which can replace the inner bottle containing the contents separately, so that the outer bottle and pump core components can be reused.

[0003] For example, the Chinese utility model patent "A cosmetic vacuum bottle with easy replacement of the inner bottle" with application number 202020638328.7 (authorization announcement number CN211996924U) discloses such a structure with replaceable inner bottle, which includes a mounting bracket, the bottom of which is threadedly connected with an outer bottle and an inner bottle, the inner bottle is placed in the inner cavity of the outer bottle, and a spray head device is installed on the mounting bracket. The spray head device includes a pressing head cap, a valve stem and a blind cover. The pressing head cap is installed on the valve stem, and the blind cover is mounted on the valve stem. When the inner bottle needs to be removed, the outer bottle is first unscrewed from the mounting bracket, and then the inner bottle is unscrewed from the mounting bracket for replacement.

[0004] However, the lotion bottle with such a structure for replacement and disassembly has certain shortcomings: during the use of the lotion bottle, consumers generally discharge liquid by pressing the push cap arranged on the top of the pump core assembly. Due to the limitation of the head structure of the push cap, in order to prevent the push cap from affecting the discharge of liquid from its liquid outlet when being pressed, the liquid outlet is generally arranged on the side of the push cap. As a result, consumers often need to use both hands to complete the liquid extraction operation process during daily use. One hand is used to drive the push cap to press down, and the other hand is used to receive the liquid from the liquid outlet arranged on the side of the push cap before applying it on the body. It is impossible to apply the liquid directly on the body by single-handed operation, which brings certain troubles to daily use.

[0005] Therefore, how to provide a lotion bottle that can achieve rapid liquid discharge without setting a push cap on the top of the pump core assembly, can directly apply the liquid to the body by pressing with one hand, and can also achieve rapid replacement of the inner bottle assembly, is a problem that technical personnel in this field urgently need to solve.
