PROBLEM TO BE SOLVED: To greatly improve convenience in carrying, cooking by heat of contents and carrying after cooking by a method wherein a plurality of tongues each having an engaging gadget are formed at a piece of platelike body, and the engaging gadgets are pushed up from the lower part of a peripheral part. SOLUTION: A supplementary device 1 for which three tongues 3, 3 and 3 are provided, extending radially, is put at the center of a capped packaging container with liquid contents housed therein with its pressure reducing pore 8 agreed with a pressure reducing pore of the capped packaging container. Bending parts 4 of the tongues 3, 3 and 3 are bent downward along the peripheral part 12a of a cap 12. Engaging pieces 5a of engaging gadgets 5 formed at the bending parts 4 are pressed for pushing up the peripheral part of the container main body, and holding is made therewith. The pressure reducing pore 8 provided at the center of the supplementary device 1 for capped packaging container is opened to correspond to the pressure reducing pore of the cap 12. Therefore, the cap 12 can be prevented from falling off by shocks during carrying or transport and contents can be prevented from being damaged or spilled. |
