Abstract
A set of sorting-stacking bins includes a plurality of tapered containers, each having upstanding, inclined walls and an integral horizontal bottom and shippable in nested condition to reduce cost. Each container has a horizontally enlarged base with depending peripheral flanges which fit over the rim of the next lower container. The bases are shipped separately flatwise against each other to reduce cost. Upon delivery, each container is snap-fitted on an enlarged base to form an integral, permanent unit, the units being vertically stackable, one on the other, with each having a large top opening for receiving a particular type waste.
