PURPOSE: A spout sealing device for a pouch type liquid container, method for sealing spout using the spout sealing device and the pouch type liquid container are provided to minimize sealing facility and simplify a sealing process of the spout. CONSTITUTION: A spout sealing device for a pouch type liquid container is composed of a pair of jig bodies(30), a heater(50), a multi-staged step(80), and a thermal insulating member(90). The pair of the jig bodies has a coupling groove(31) to be engaged with a seal(21) of a spout(20). The heater is contained at the jig body to weld the opening ends of the container. The multi-staged step is formed at the outside of the coupling groove to weld the opening ends of the container at different conditions by the single squeezing of the jig body. The insulating member is prepared at the lowest portion of the step to insulate the heat to the opening end of the container.
