Pumping-type cosmetic container

Abstract

A pumping-type cosmetic container is characterized by an elastic discharging portion being formed on the top of a pumping member and opened by the pressure of contents of the container, and a sealing shaft being coupled to the elastic discharging portion such that sealing is enabled without the use of a separate check valve and air is prevented from entering into a bellows.
