Ringless paint container

A wide-mouth cylindrical, rolled metal container having generally constant wall thickness in combination with a removable, resealable lid comprising:

• a. said lid having a generally circular configuration with an annular sealing groove formed adjacent its peripheral edge;
• said sealing groove defined by continuous longitudinally-extending inner and outer sealing walls with a bight wall therebetween thus forming an inverted, U-shaped groove;
• b. said container having a generally cylindrical, longitudinally-extending side wall of generally constant wall thickness, a circular bottom wall at one end of said side wall and a generally circular top opening at the other end of said side wall, said container side wall further defined by a configured rim portion adjacent said top end and a generally constant diameter cylindrical body portion extending from said bottom wall to said rim portion;
• 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 only said sealing walls of said lid, said outer sealing wall of said lid establishing approximately an annular line contact with said container's bead, said curled bead having an outside diametrical distance slightly less than the outside diametrical distance of said cylindrical body portion so that said container is a wide mouth container;
• ii) a longitudinally-extending sealing wall segment generally parallel to said container's side wall and positioned radially inwardly therefrom adjacent to and depending from said curled bead and adapted to be in area contact over a substantial portion of the length thereof with said lid's inner sealing wall to define a longitudinally-extending, frictional sealing wall segment, said sealing walls compressing said curled bead, and iii) a straight frusto-conical wall segment extending from said sealing segment to said container's side wall and having a single reverse bend formed in said frusto-conical wall segment adjacent said body portion of said side wall, said single reverse bend having a first arcuate bend portion contiguous with a second arcuate bend portion, said first bend portion sharper than said second bend portion to form a relatively sharp protrusion in the shape of an annular groove, said second bend portion blending into said frusto-conical wall segment and said first bend portion terminating at the line of demarcation between said rim portion and said cylindrical body portion.
