Stacking container with window

摘要

The container sides (1-4) extend conically downwards. The top edges of opposite walls (1,3) each have at least one aperture (17). Projections (29) on the sides of the base (5) of a second container slide into and engage in this aperture, when it is stacked on the first one. Alternately, there may be holders (21,22) for the projections on the top side edges. There are e.g. twice as may holders as there are projections. Each projection is formed by a rib (24) on the outside of a wall. Each aperture is formed by a hollow rib.
