STEAM HEATING DEVICE

摘要

PURPOSE:To obtain a heating device of an excellent ever-heating property and heating efficiency regardless of having the smallest formation by cutting off an aperture blocking sheet and a pyrogen sealing sheet simultaneously by pulling a cord whose one end is exposed out of a container, and dispersing the steam generated by a hydration reaction of the exposed pyrogen and the water surrounding the pyrogen upwards from the opened aperture of the blocking sheet of the container aperture. CONSTITUTION:By pulling the other ends of thread-form opening members 10 protruding from a heating container 1 in the arrow direction, a part of an engine tray 6 receives a tensile force, and the center of the edge of a water impermeable sheet 11 covering an aperture surface 6a is cracked. After that, one end 7b of a pyrogen bag 7 is cracked almost at the position same as the water impermeable sheet 11. In this case, the cracks are made in a shearing condition, and the end 7b can be broken without requiring a strong force. As a result, the pyrogen bag is, together with the water impermeable sheet 11, opened from one end 7a side to the other end 7b side in the tensile force direction, and the pyrogen bag 7 is opened largely from the center. Consequently, the water 9 surrounding the whole circumference of the pyrogen bag 7 invades into the pyrogen bag 7, contacting almost all the surface, and a high temperature steam is generated by the hydration reaction of the pyrogen.
