Cosmetic bottle capable of shaking for pressurization

Abstract

The invention relates to the technical field of cosmetic bottle packaging, in particular to a cosmetic bottle capable of shaking for pressurization. Thecosmetic bottle comprises a cosmetic bottle anda spray head. The spray head is connected to the upper port of the cosmetic bottle; an accommodating cavity is formed in the cosmetic bottle; the lower end of the spray head is communicated with the accommodating cavity; the accommodating cavity is provided with a first inner container and a second inner container which are flexible or elastic; the upper portion of the second inner container is connected with the inner wall of the accommodating cavity; the first inner container is located under the second inner container; the first inner container is filled with gas and liquid, the gas is easily dissolved in the liquid, and a part of the gas is separated from the liquid after the solution is vibrated, so that the inner pressure of the first inner container is increased, the first inner container expands to extrude the second inner container, and the inner pressure of the second inner container is increased; and after standing for a period of time, the gas is dissolved in the liquid again, the pressure in the first inner container is reduced, the first inner container shrinks, and the stress on the second inner container disappears. When the spray head is pressed, under the action of internal pressure, the force for pressing the spray head can be reduced, the force applied by fingers is reduced, and the comfort is improved.
