Food packaging cover

The food packaging cover of claim 1, 4 or 21 wherein said first and second furrows are alternately arranged in side by side relation.

The food packaging cover of claim 1, 4 or 21 wherein said top section is encompassed by a circumferential groove.

A food packaging cover comprising an elevated top section, a depending wall section and a shoulder section interconnecting the top and wall sections, said wall section formed from dissimilar first and second alternately arranged vertical furrows having inwardly converging side walls joining to form upright recessed ribs, said shoulder section formed from a plurality of outwardly projecting flats disposed along the perimeter of said top section and having first and second inwardly converging gusset means alternately disposed between adjacent flats for interconnecting said furrows with said flats and for substantially uniformly distributing a load placed on said top section to said wall section.

A food packaging cover comprising an elevated top section, a depending wall section and a shoulder section interconnecting the top and wall sections, said wall section formed from first and second alternately repeating upright furrows, said first furrows increasing in depth from one end to the other and said second furrow increasing in depth in the opposite direction, said furrows having inwardly directed converging side walls joining to form recessed vertical ribs, the adjacent side walls of adjacent first and second furrows converging outwardly to form outwardly directed ribs.

A food packaging cover comprising:

• an elevated top section, a depending wall section, a shoulder section interconnecting said top and wall sections, and a tray locking means disposed at the base of said wall section, said wall section being formed from first and second vertical furrows repeating in a predetermined pattern, each of said first furrows comprising a pair of inwardly converging side walls which terminate in a recessed first rib, wherein the depth of said first furrows increase from one end to the other, each of said second furrows comprising a pair of inwardly converging side walls which terminate in a recessed second rib, wherein the depth of said second furrows increase in the opposite direction of said first furrow and the adjacent side walls of each said first and second furrows converge outwardly to form a protruding third rib.

A food packaging cover comprising an elevated top section, a depending wall section and a shoulder section interconnecting the top and wall sections, said wall section formed from first and second alternately arranged vertical furrows having inwardly converging side walls joining to form upright recessed ribs, said first furrow increasing in depth from one end to the other and said second furrow increasing in depth in the opposite direction, said shoulder section formed from a plurality of outwardly projecting flats disposed along the perimeter of said top section and having first and second inwardly converging gusset means alternately disposed between adjacent flats for interconnecting said furrows with said flats and for substantially uniformly distributing a load placed on said top section to said wall section.

A food packaging cover comprising an elevated top section, a depending wall section and a shoulder section interconnecting the top and wall sections, said wall section being formed from vertical furrows having inwardly projecting ribs, said shoulder section including a plurality of symmetrically arranged outwardly pointed triangular shaped flats having one edge disposed along the perimeter of said top section and gusset means extending between and interconnecting the adjacent edges of adjacent flats to form an inwardly converging furrow in substantial endwise alignment with each of said vertical furrows for substantially uniformly distributing a load placed on said top section to said wall section.
