Abstract
An especially configured, ringless, container-lid, design is disclosed having improved sealing characteristics applicable to paint containers for the consuming public. The rim portion of the container is provided with a tapered, especially shaped wall section terminating in a circular bead which is received in a sealing groove in the lid. The wall section flexes to maintain the seal established between the lid and the bead while sufficiently rigidized to prevent collapse of the container's sidewall. The design disclosed permits easy modification of the container for serially stacking thereof.

A cylindrical metal container in combination with a removable, resealable lid comprising:
- (a) said lid having a generally circular configuration with an annular sealing groove formed therein, said sealing groove defined by continuous longitudinally extending inner and outer sealing walls with a bight wall therebetween forming an inverted, U-shaped groove;
- (b) said container having a generally cylindrical longitudinally extending side wall defined by a configured rim portion adjacent to the end of said container and a generally cylindrical body portion contiguous with and extending from said rim portion towards the bottom of said container;
- (c) said rim portion adapted to receive said lid for closing said top opening and further including (i) said top end of said side wall curled in a bead for sealing engaging said sealing walls of said lid, (ii) a longitudinally extending sealing wall segment generally parallel to said container's side wall depending from said curled bead and adapted to be in contact over a substantial portion of the length thereof with one of said lid's sealing walls, and (iii) a frusto conical wall segment extending from said sealing segment to said container's side wall and having rigidizing means formed therein for resisting longitudinal deflection of said rim portion.
