A sealed container includes a base jar for containing a substance and a removable lid therefor. The base jar includes an upper portion with a screw thread and an upper wall extending inwardly and upwardly therefrom having a circular brim which defines a wide mouth opening, a brim portion with at least a 10% reduction, and an inside edge. The removable lid includes an encircling member extending downwardly from a top wall with a mating screw thread for the screw thread of the base jar. For sealing with the base jar, the removable lid also includes a circular projection extending downwardly from the lid which engages and seals with the circular brim. For additional sealing, the removable lid further includes a circular flexible flange extending downwardly from the lid having a tip which is radially flexed relative to a remainder of the flange upon engagement with an upper wall of the jar to seal therewith. For further sealing and primary sealing, the top wall of the lid also includes a circular centering and sealing rim which, before engagement of the circular projection with the circular brim, engages the inside edge of the circular brim to form a seal therebetween as well as to positively locate the circular projection vertically adjacent the circular brim. |
