A packaging container formed by folding a blank into a pyramid shape, the blank comprising a rectangular bottom wall and four lateral walls which consist of front and rear walls and a pair of side walls. Each lateral wall has a maximum width between points where side edges of the adjacent lateral walls are joined together. The side walls each has a projection at the top end and a pair of laps at the side end portions. The blank is folded along each of the four sides of the bottom wall and boundaries of the lateral walls to raise the latter with respect to the bottom wall, while the side walls also are so folded that the laps face and abut the front and rear walls, respectively, with the projections being sandwiched between the top ends of the front and rear walls. The top ends and the projections are fastened together with a staple.
