<p>The present invention relates to a pouch pack having a pressure outlet formed at the time when a sealing region is thermally fused to therefore substantially reduce the amount of time required for the manufacturing process, with the pressure outlet being open precisely under pressure. A pouch pack having a pressure outlet according to the present invention comprises a main body which is formed of two opposedly facing sheets with a sealing region thermally fused in a hermetic manner by a heating pressure mold designed for thermally pressing a target sealing region and defines a storage space inside thereof; and a pressure outlet which is integrally formed on the sealing region of the main body and opens under pressure to discharge a content kept within the storage space. As a cavity is formed in a part of the heating pressure mold, only a corresponding region of the cavity experiences a reduced heating temperature and reduced pressure while the sealing region is being thermally fused, so that the pressure outlet and the sealing region can be formed at the same time. Alternatively, a recess is formed in a part of the heating pressure mold and a metallic material having a heat conductivity lower than that of the heating pressure mold is seated in the recess, so that only a corresponding part of the metallic material experiences a reduced heating temperature while the sealing region is being thermally fused so as to allow the pressure outlet and the sealing region to be formed at the same time.</p> |
