<p>PROBLEM TO BE SOLVED: To prevent damage of a carton container at the time of forming the container by respectively disposing a heater nozzle having a hot air outlet and a baffle plate on inner and outer surfaces of a bottom of the container, and providing a plate of the shape that a gap is converged toward an end without providing a hot air outlet. SOLUTION: An inner surface of the container is activated by hot air from a hot air outlet provided at a heater nozzle, and an outer surface of the container is activated by hot air from hot air outlets provided at three baffle plates. The plate 50 does not have hot air outlet. An upper surface and bottom are opened. And, a side 52 opposed to a side of the nozzle is provided with a part for mounting by a nut, and a central part is largely opened. Further, a side 54a opposed thereto is inclined to converge a gap to the side 52 toward downward. Thus, heat near the plate 50 is efficiently exhausted out of an apparatus via the opening. And, synthetic resin film of a site necessary to form a bottom of the carton container can be effectively activated.</p> |
