PROBLEM TO BE SOLVED: To improve tightness of sealing up and to ensure safety for pouring out of hot water by a method wherein a covering member main body having an unsealing tab is made from a laminated body comprising a paper lamina and a sealant lamina, and a seal-up seal is stuck with a seal-up material to the covering member so as to cover a hole for pouring out hot water provided at the covering member. SOLUTION: A covering member main body is formed in a shape the same as an opening 44 of a container main body 40 while being equipped with an unsealing tab 12 and a hole 16 for pouring out hot water, and stuck to a flange 42 of the container main body 40. Then, a seal-up seal 14 is stuck with a seal-up material 20 to the covering member main body so as to cover the hole 16. In this case, the seal-up material 20 is applied to the seal-up seal 14, excluding positions corresponding to a tab 18 and the hole 16. The covering member main body is formed by laminating a sealant lamina such as an olefine resin, heat-sealing varnish, hotmelt resin or the like to a laminated body made up by combining paper, metal, PET and the like. Furthermore, a thermoplastic resin, viscous adhesive or the like is, for instance, used as the seal-up material 20.
