Abstract
A cosmetic container includes a piston in which content contained in the container always reaches a content inlet of an airless discharge pump as the piston rises upward along and on an inner wall of the container with operation of the airless discharge pump. More specifically, the content amount remaining in the container is indicated in association with the rising movement of the piston. The cosmetic container includes a container body, an airless discharge pump installed to the container body, a piston installed in the container body so that a topmost level of content contained in the container body reaches a content inlet of the airless discharge pump as the piston moves upward along and on an inner wall of the container body with operation of the airless discharge pump, and an indicator indicating content amount remaining in the container body in association with rising movement of the piston.
