ABSTRACT:
A compound packing container consisting of an outer casing made of a paper material having an inner bag member arranged to be contained therein. The outer casing has a series of adjacent first, second, third and fourth side panels arranged to be formed into a tubular drum portion with first, second, third and fourth upper flaps and first, second, third and fourth lower flaps extending respectively upwards and downwards from the side panels through an upper and a lower horizontal fold. A pair of opposite vertical folds are made in the vertical center portions of the first side panel, the first upper flap and the first lower flap and in the vertical center portions of the third side panel, the third upper flap, and the third lower flap. The flat inner bag member is made of a rectangular waterproof sheet arranged in the outer casing having front and rear sheet portions, opposite side edges extending along the whole length of the opposite vertical folds of the outer casing, a bottom closed edge and an open top edge having an opening defined by the front and rear sheets. Both sides of an intermediate portion of the inner bag member are adhered to the inner surface of the side panels and both surfaces of each of the bottom portions around the corners on both ends of the bottom edge are adhered respectively to the first and third lower flaps at each of two triangular adhesion regions. The triangular adhesion regions have apexes at the lower ends of the vertical folds.
