ABSTRACT:
Nestable and stackable box comprising a rectangular bottom, two side walls and a back wall, which walls diverge, starting at the bottom, a lowered front wall and a fold-away stacking support. The front of each side wall has been bevelled off to make an obtuse angle with the top of the side wall, and each side wall has been provided with an opening near its front, the vertical plane bounding the opening at the front being totally before the perpendicular dropped from the vertex of the obtuse angle between the front and the top of the side wall upon the bottom. The part of the wall section between the opening and the front of the side wall goes outward as it goes downward, to a distance of one to three times its horizontal wall thickness, to form a ridge having a width of one to three times the horizontal wall thickness. An inside protrusion has been provided on said ridge and against the outward-going wall section, and on the outside of the side wall and below the opening and outside protrusion, the underside of the outside protrusion being at a distance of at least one third of the side wall height beneath the ridge and extending sidewards not further than the side wall thickness plus the nesting clearance, all this in such a way that in a nesting arrangement the outside protrusion falls behind the inside protrusion.
