Other parts are laminated to form a laminate, leaving the outermost layer and the innermost layer, and a hole for spouting is formed in the laminate, and then a thermoplastic resin is attached to the front and back of the laminate having the holes. Alternatively, a pouring hole formed by ruder processing and having the thermoplastic resin is formed with a hole slightly smaller than the hole so that the end face of the base paper does not come out in the hole. This is the method of forming the outlet.
