Abstract
A portable cosmetic container is disclosed. The portable cosmetic container includes a tube that has a receiving space with an opening at one end, and a crease is located at a bottom portion of the receiving space, so that a user can easily break the tube from the crease to form the opening of the receiving space. Substance is partially filled in the receiving space, and air therein is extracted to form a negative pressure status. It is advantageous that when a user breaks the tube from the crease, the substance will not randomly spray out since the air pressure moves towards the opening to keep the substance in the receiving space.
