Abstract
An integral wall formation for fruit and vegetables containers made of plastic has an outer surface having a plurality of longitudinally extending outer legs wherein adjacent legs define outer apertures therebetween. An inner surface has a plurality of longitudinally extending inner legs wherein adjacent inner legs define inner apertures therebetween. At least a majority of the inner apertures are staggered with respect to the outer apertures and in combination therewith form openings in regular arrangement for airing goods stored in the container. At least one crossbar extends transversely to and is adjoined with the inner legs and outer legs.

An integral wall formation for boxes and containers, said wall formation comprising:
- an outer surface having a plurality of longitudinally extending outer legs wherein adjacent ones of said outer legs define outer apertures therebetween:
- an inner surface having a plurality of longitudinally extending inner legs wherein adjacent ones of said inner legs define inner apertures therebetween, and further wherein at least a majority of said inner apertures are staggered with respect to said outer apertures and in combination form openings in regular arrangement for airing goods stored in the container;
- and
- at least one crossbar extending across said inner and outer apertures and transversely to and adjoined with said inner legs and said outer legs.
A wall formation for the construction of containers for the storage and transport of fruit and vegetables wherein said wall formation comprises a generally rigid planar sheet of polymeric material having an outer perimeter of predetermined dimensions and an inner portion defined by said perimeter, said inner portion having a first surface having a plurality of first apertures and a second surface having a plurality of second apertures staggered from said first apertures and in combination therewith defining a plurality of openings therethrough for allowing air to flow to the fruit and vegetables, said openings separated by a plurality of connecting bars of said rigid sheet, and further wherein said plurality of connecting bars define a majority of said openings such that each of said majority of said openings includes one of said first apertures staggered from one of said second apertures, and a crossbar separating said first surface from said second surface and extending transversely to said connecting bars.
