ABSTRACT:
A sealed container includes a base jar for containing a substance and a removable lid for closing and sealing the base jar. The base jar includes a bottom wall, a side enclosure extending upwardly from the bottom wall having an upper portion with a screw thread, and an upper wall extending inwardly and upwardly from the upper portion of the side enclosure having a circular brim which defines a wide mouth opening for the base jar. The removable lid includes a top wall and an encircling member extending downwardly therefrom with a screw thread which matingly engages with the screw thread of the upper wall 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 the upper wall of the jar to seal therewith as the circular projection and circular brim matingly engage. Preferably, the top wall of the lid also includes a circular centering rim which, before engagement of the circular projection with the circular brim, engages an inside surface of the circular brim to positively locate the circular projection vertically adjacent the circular brim. A stacking mechanism is further provided so that the containers can be stacked one on top of another.
