<P>PROBLEM TO BE SOLVED: To provide a packaging container 10 that minimizes the entire height of the stack of many packaging containers and, at the same time, prevents all the packaging container from inclining toward a sidewall 12c opposite a sidewall 12a provided with support projections 16 for wrapping film. <P>SOLUTION: The packaging container 10 obtained by molding a foam resin sheet so as to include: a substantially rectangular tray portion 15 having a bottom 11 and sidewalls 12 inclining outward while spreading upward in the direction of the opening from the perimeter of the bottom 11; and the support projections 16 for supporting wrapping film, the projections being formed by molding part of one sidewall 12a upward so as to have a mountain-like shape. In the packaging container 10, the sidewalls other than the one that has the support projections 16 have thick protuberant portions 20, which protuberate outside from the external surfaces of the sidewalls 12. The locations where the protuberant portions 20 are formed are such that when the packaging containers 10 of the same shape are stacked in the same direction, the parts where the protuberant portions 20 are formed come into contact with the internal surface or top of the sidewalls 12 of the packaging container located below it, thereby the packaging container located above it can be held in position parallel to the packaging container located below it. <P>COPYRIGHT: (C)2011,JPO&INPIT |
