As shown in the publication, a blank plate having a thermoadhesive resin layer on at least one outermost surface of a base material layer mainly composed of paper is used, and the blank plate is hollow with the thermoadhesive resin layer inside. Form a peripheral wall by winding both side edges facing each other in a circular shape, filling the lower end opening of the blank plate and the space between both side edges and covering the peripheral edge of the upper opening to form a skeleton member with synthetic resin so as to be integrally attached to the blank plate. There is known a packaging container in which a bottom portion, a columnar portion and an upper edge portion are constituted by the skeleton member. This type of packaging container is called a Pillard container and is used as a container for detergent, for example.
