Abstract

The invention protects an application body as well as reducing a remaining amount of a liquid cosmetic. A bag-like container accommodates liquid cosmetic therein and provides an opening neck portion to communicate the inner side and the outer side thereof, a pipe portion in the opening neck portion extends to the bag portion bottom side. The pipe portion peripheral surface has an opening for the liquid cosmetic going into an internal portion. An application body in a lid portion goes into the pipe portion by installing the lid portion to the opening neck portion to reach the opening position. If a user pushes and squeezes the bag portion, the liquid cosmetic goes into the pipe portion through the opening, the application body dips into the liquid cosmetic to run short of the liquid cosmetic and to protect the application body by the pipe.
