The present invention provides a container having a sheet metal floor, a sheet metal sidewall shell having four round seamless corners and a maximum of two sidewall seams. The container can be a casket with a lid, and a pair of hinges pivotally attaching the lid to the sidewall. The sheet metal sidewall shell can be made from a stretch-bent sheet metal sidewall panel. In some instances, the sheet metal sidewall shell has only one seam that may or may not be a welded seam.

6. The casket of claim 1 , wherein said double torsion spring is attached to one of said sheet metal sidewall and said lid, and said cam is attached one of said sheet metal sidewall and said lid that does not have said double torsion spring attached thereto.
7. The casket of claim 6 , wherein each of said hinges has a base plate attached to one of said sheet metal sidewall and said lid, said two spaced-apart torsion springs attached to said base plate.
8. The casket of claim 7 , wherein said base plate is rigidly attached to said lid and has a back edge lip adjacent to a back portion of said lid.
9. The casket of claim 8 , wherein said back edge lip provides support for said base plate on said lid.
10. The casket of claim 1 , wherein said cam is a gooseneck-shaped rod that engages said C-shaped section of said double torsion spring.
11. The casket of claim 10 , further comprising a bearing on said C-shaped section of said double torsion spring, said gooseneck-shaped rod engaging said bearing.
12. The casket of claim 11 , wherein said bearing is a sleeve on said C-shaped section.
