Claim:
A container having a base and lid formed of at least one sheet, wherein said base and lid are centered on a vertical axis, wherein said base has a base rim portion with an upward-facing base support wall that extends at least 270° around said axis, and said lid has a lid rim portion with a lid rim part that lies on said base support wall, with said lid rim part having an outer lid rim edge, wherein: said base rim portion has a raised base outer rib that lies immediately radially outside said base support wall, to block access to said lid rim part, said base outer rib extending along substantially the entire base rim portion except that said base outer rib has a pair of gaps; said base rim portion has a primarily radial tear gap line lying in at least one of said gaps and has a pivot gap line lying in the other of said gaps and said base rim portion forms a primarily circumferentially-extending tab between said gap lines and along said base support wall; said base rim portion also has a separable line extending primarily circumferentially between said gap lines and lying radially inward of said tab, so that after said tear gap line is torn said tab can be moved to expose the lid rim part between said gap lines.
