Abstract
A container for sliced meat products or the like has a base including a marginal base flange, a raised pedestal, and a short peripheral sidewall connecting the pedestal to the marginal base flange. A cover is also provided including a marginal cover flange and a cavity, the cavity being formed by a raised top wall and a long peripheral sidewall connecting the marginal cover flange to the top wall. A plurality of concave channels are provided along the interior surface of the long peripheral sidewall. These channels extend from the top wall and terminate at a height above the marginal cover flange which is greater than or equal to the height of the short peripheral sidewall of the base. A plurality of depressions or grooves are also provided in the upper surface of the pedestal. Preferably, the grooves extend substantially perpendicularly to the adjacent portion of the short peripheral sidewall and are equidistantly spaced. In addition, the end of each groove adjacent the short peripheral sidewall is matingly positioned adjacent a corresponding lower end of a respective concave channel.
