Abstract
There is disclosed a dry bulk hopper system that includes a generally frustoconical bottle and a base having a tapered wall that defines a cradle for holding the bottle. The bottle has locking tabs disposed at bottom end thereof that cooperate with engagement ledges to secure the bottle to the base when the bottle has been received into the base in a first orientation, but not in a second orientation. Extruded support columns are disposed inside an interior of the base to distribute loads created by material in the bottle when the system is raised by a forklift.
