Conical steel drum
A tapered steel body that nests empty, so the return leg and empty storage stop costing what they cost with a straight-sided drum.
- There is a repeatable route back, or empties collect at one site
- A liner keeps the drum clean enough to skip washing between trips
- Empty storage space is scarce at one or both ends
- Deliveries scatter to many small receivers with no return flow
- The product needs washing that costs more than a new container
