Rotary pressing type vacuum flask

Abstract

The invention relates to a rotary pressing type vacuum flask comprising a flask body, a shoulder sleeve, a flask cap, a button, a material cavity, a large piston, a material pumping barrel, a small piston, a feeding port, a feeding one-way valve, a discharging port and a discharging one-way valve; the button is provided with a discharging pipe, the flask cap is rotationally connected with a shaftshoulder, a limiting ring strip is arranged on the periphery of the top surface of the shoulder sleeve, a limiting ring is located on a descending path of the button, an opening mark and a closing mark are arranged on the outer side of the flask cap, an indication mark is arranged on the outer side of the shoulder sleeve or the outer side of the flask body, the opening mark is aligned with the indication mark, and the limiting strip is located right below an avoidance notch; and the opening mark and the indication mark are not aligned with each other, and the limiting strip is staggered with the avoidance notch. According to the rotary pressing type vacuum flask in the invention, the button is protected from accidentally extruding out of cosmetics due to external force in the mode that thebutton is embedded into the flask cap, the limiting strip and the avoidance notch in the rotatable button jointly cooperate to ensure that the button can be pressed down only by rotating to a specific position, accidental pressing of the button is further prevented, meanwhile, high button damping is not needed, and the user experience is improved.

Description

technical field [0001] The invention relates to a cosmetic packaging material, in particular to a rotary pressing vacuum bottle. Background technique [0002] With the development of society and the progress of mankind, cosmetics are rapidly popularized in public life, and the types of cosmetics are continuously refined, and emulsion-like cosmetics occupy a large proportion. Emulsion-like cosmetics are usually kept in extrusion containers. In order to improve the cosmetics Grade and user experience, the extrusion container is usually set as a pump container. The existing pump container is usually covered with a protective cover on the nozzle or directly exposes the nozzle to increase the pressure resistance to prevent accidental extrusion of cosmetics. This method is inconvenient to use. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a rotary press type vacuum bottle. [0004] The technical...
