Stacking tray and lid assembly

A stacking tray and lid assembly for food, comprising:

• (a) a tray of generally rectangular configuration having an upper surface and multiplicity of compartments for receiving food, depending from said upper surface and spaced inwardly from the side margins of said tray to provide a peripheral portion thereabout, said compartments having a sidewall and a generally planar bottom wall extending parallel to said upper surface, said bottom walls being coplanar;
• and
• (b) a lid of cooperating generally rectangular configuration with two pairs of opposed sides and including a generally planar body and a depending peripheral flange with cutouts extending through said flange on a pair of opposite sides of said lid, said flange on each of said pair of opposite sides having a multiplicity of bosses on its inner surface into engagement below the outer edge of said peripheral portion of said tray, said bosses being disposed on opposite sides of said cutouts, said cutouts facilitating flexing of said flange to enable said bosses to pass over said outer edge of said tray, said bosses being vertically elongated and having an inclined surface at their lower ends to facilitate movement thereof over the edge of said tray, said bosses being spaced downwardly from the upper end of said peripheral flange a distance greater than the thickness of said edge of said tray peripheral portion which engages thereabove.

A stacked tray assembly comprising:

• (a) a first tray of generally rectangular configuration having an upper surface and multiplicity of compartments for receiving food, depending from said upper surface and spaced inwardly from the side margins of said tray to provide a peripheral portion thereabout, said compartments having a sidewall and a generally planar bottom wall extending parallel to said upper surface, said bottom walls being coplanar;
• (b) a lid of cooperating generally rectangular configuration with two pairs of opposed sides and including a generally planar body and a depending peripheral flange with cutouts extending through said flange on a pair of opposite sides of said lid, said flange on each of said pair of opposite sides having a multiplicity of bosses on its inner surface into engagement below the outer edge of said peripheral portion of said tray, said bosses being disposed on opposite sides of said cutouts, said cutouts facilitating flexing of said flange to enable said bosses to pass over said outer edge of said tray, said lid having a multiplicity of upstanding positioning ribs on said peripheral portion;
• and
• (c) a second tray seated on said lid, said tray having an upper surface and multiplicity of compartments for receiving food, said compartments depending from said upper surface and being spaced inwardly from the side margins of said tray to provide a peripheral portion thereabout, said compartments having a sidewall and a generally planar bottom wall extending parallel to said upper surface and said bottom walls being coplanar, said positioning ribs of said lid receiving therebetween the lower portions of the sidewalls of the compartments of a tray seated thereon.
