PURPOSE: An apparatus for isolating the heat of a paper container is provided to allow a user to safely grip the paper container even though hot water is received in the paper container. CONSTITUTION: The paper container comprises a reinforcement protrusion(2) formed at desired upper and lower positions of a container body(1), a vertical leg part(3) extending downward from the bottom surface of the container body, and a space(5) capable of isolating the transmission of heat between an outer shell(4) and the container body. The space extends from the upper edge of the container body to the lower end of the vertical leg part. The reinforcement protrusion is applied with an adhesion so as to make the outer shell attached and fixed onto the container body.
