We describe the WERIT stack and nest containers as 2-stage containers. Empty containers can be nestled within each other and thus save space. Full containers can be turned through 180° and stacked on the inside edges such that the product does not get damaged. All stack and nest containers have the following properties: smooth inner wals for fast and simple cleaning, 65% reduction in volume, high levels of stability when stacking due to centering, rounded-off grids for safe transport, textured areas.
