A cosmetic bottle with its own pressure

Abstract

The invention discloses a self-contained pressure cosmetic bottle, which mainly relates to the field of cosmetics. It is applied to the storage of liquid cosmetics and solves the problem in the prior art that cosmetics are easy to oxidize after opening the bottle. The technical points are as follows: the bottle body, Bottle cap and spray mechanism; the bottle cap is fixed on the bottle body through threaded connection; the spray mechanism is fixed inside the bottle cap through a spring; the bottle cap is divided into an inner bottle cap and an outer bottle cap; the inner bottle cap It is threadedly connected with the outer bottle cap; the inner bottle cap is provided with a pressure chamber; the spray mechanism is provided with a pressing head and a spray head; the pressing head is provided with a pressure channel; the lower end of the spray head is provided with a small single Directional valve; the present invention provides pressure for liquid extrusion by setting a pressure chamber instead of a pressure pump, so that the cosmetics in the cosmetic bottle can be completely pressed out; the present invention also isolates the outside world from the cosmetic bottle in the bottle through a small one-way valve, so that Cosmetics will not be oxidized.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a cosmetic bottle with its own pressure. Background technique [0002] With the improvement of living standards, cosmetics have increasingly become an indispensable part of life, especially for women. Various cosmetics are piled up on the dressing table, among which bottled cosmetics are mostly used, and lotions, essences, perfumes, etc. are all used Cosmetic bottle storage. [0003] The traditional cosmetic bottle adopts the pressure pump structure. By pressing the nozzle of the pressure pump to drive the piston rod of the pressure pump, the material in the bottle is squeezed out and discharged from the nozzle. This makes the liquid in the liquid storage chamber in the pressure pump finally separated from the outside. In contact with air, this part of cosmetics will be oxidized by oxygen in the air, thus losing its due effect. For this reason, preservatives must be added to the cosmeti...

Problems solved by technology

[0003] The traditional cosmetic bottle adopts the pressure pump structure. By pressing the nozzle of the pressure pump to drive the piston rod of the pressure pump, the material in the bottle is squeezed out and discharged from the nozzle. This makes the liquid in the liquid storage chamber in the pressure pump finally separated from the outside. In contact with air, this part of cosmetics will be oxidized by oxygen in the air, thus losing its due effect. For this reason, preservatives must be added to the cosmetic materials to ensure that the materials will not be oxidized and deteriorated. However, preservatives will have adverse effects on the human body. ; Moreover, the inside of the cosmetic bottle is not connected with the outside world, the pressure difference between the inside of the cosmetic bottle and the outside world is getting bigger and bigger, and the working efficiency of the pressure pump is getting lower and lower, so that the cosmetic bottle in the cosmetic bottle cannot be used completely
