Referring to fig. 14, when makeup is performed using the cosmetic bottle of this embodiment, a user presses down on the push cap 3, the push cap 3 moves downward against the pump core assembly 4, the spring 5 is gradually compressed and deformed by downward movement of the pump core assembly 4, and negative pressure is formed in the inner bottle 7 as the lower end of the pump core assembly 4 moves downward into the inner bottle 7; under the action of the atmospheric negative pressure, the large piston 8 at the bottom of the inner bottle moves upwards towards the direction of the pressing cap 3, and then the large piston 8 pushes the whole body of the material body 13 contacted with the large piston upwards, so that the liquid level of the material body 13 is lifted to a new position at the original position, the internal and external atmospheric pressures of the inner bottle are balanced, and the spring 5 is changed into a telescopic state from compression deformation; by pressing the pressing cap 3 downwards in a reciprocating way, the material body 13 in the inner bottle of the cosmetic bottle can be continuously lifted upwards for the user to use; referring to fig. 15 and 16, when the amount of the material 13 in the inner bottle 7 is small, even a residual amount remains, the material 13 flows to the gathering groove 83 at the central position of the arc-shaped body 80, so that a large amount of the material is gathered in the gathering groove 83, and the material in the gathering groove 83 is sucked in through the inlet end 40 of the pump core assembly 4 and then is output through the outlet end of the pump core assembly 4 again by pressing the pressing cap 3 and the pump core assembly 4.

Referring to fig. 15 and 16, by providing such a suction plane 87 at the bottom of the accumulating groove 83, when the residual material in the inner bottle is pumped by the pump core group 4, the pumping unit 4 can still fully pump the very little residual material in the accumulating groove 83 when the residual material is at the use limit node of the accumulating groove 83, and the effect of no residual on the residual material in the cosmetic bottle is really realized. Of course, the suction plane 87 is preferably of the same size as the feed opening 40 of the core assembly, i.e., so that the feed opening 40 can be exactly and completely abutted against the suction plane 87, so that the pumping action of the core assembly can be utilized to suck the limited residual material on the suction plane 87 into the core assembly through the feed opening 40 and out through the discharge opening end of the core assembly.

In addition, in order to more stably confine the spring in the space formed by the pressing cap and the inner cap, referring to fig. 7, the present embodiment is formed with a limiting annular wall 32 inside the pressing cap 3 and outside the pressing rod 31, and the upper end of the spring 5 is confined in the limiting annular wall 32.
