Abstract

A tray of molded pulp or the like is provided for the packaging of meat, poultry or fish in conjunction with an overwrapped transparent film. The tray bottom is formed of a plurality of inverted V or U-shaped ribs joining or intersecting in two directions and defining open windows therebetween, the height of each inverted V-shaped rib being on the order of several times the thickness of the remainder of the tray, and the total volume of the inverted V-shaped ribs being approximately equal to the volume of a bottom of an imperforate bottom tray of the same size. [US3718274A]

Claims (18)

40355/2

6. A tray in accordance with claim 1 wherein said primary ribs extend generally parallel to said side and end walls and meet at right angles to form generally rectangular open windows.
7. A tray in accordance with claim 1 wherein said secondary ribs are of reduced height above said gutterlike bottom wall and are filled in on the bottom adjacent said end and side walls.
8. A tray in accordance with claim 1 wherein said secondary ribs are of height substantially equal to said primary ribs, and are of about 10° included V-angle. 40355 / 2
9. A tray in accordance with claim 1 wherein said primary ribs have a varying included V-angle of about 10°-30°.
10. A tray in accordance with claim 1 wherein said peripheral lip comprises a relatively large and thick portion dome-shaped in cross-section, and a horizontal portion extending outwardly from said dome-shaped portion at a location substantially below the top of the dome-shaped portion.
11. A tray in accordance with claim 10 molded of a wood pulp having large free liquid accepting capacity, and provided with a liquid impervious coating on the bottfcJm surface thereof,
12. In a generally rectangular molded tray for the packaging of meat, fish or poultry in conjunction with a transparent overwrap film heat-sealed thereabout, said tray comprising a pair of upwardly and outwardly |aiclined side walls, each said side wall forming a long side of said tray; a pair of upwardly and outwardly inclined end walls, each said end wall being adjacent to ends of said side walls, and thereby forming the rectangular configuaation of said tray; a generally rounded corner between each said side wall and each said end wall; and a peripheral lip extending outwardly from said side and end walls and defining the periphery of said tray, the improvement comprising; means for suspending the meat, fish or poultry at a substantial height above the exterior bottom of the tray so that the meat, fish or poultry will not contact the overwrap film along the bottom of the tray, and for providing improved oxygen breathing through the tray bottom and for providing visibility through the tray bottom, said breathing and suspending means comprising a plurality of strong, substantially solid primary ribs of inverted V. -shaped cross-section with rounded apices and height substantially greater than the thickness of said side and end walls, some of said primary ribs extending in one direction and other of said primary ribs extending in a different direction, said primary ribs joining and defining therebetween 40355/3 including an annular rib and a peripheral channel between said end and side walls and said primary ribs, wherein said annular transition zone comprises a gutter-like bottom wall and secondary ribs extending there-across, and wherein said secondary ribs are staggered in relation to said primary ribs .
13. A try in accordance, with claim 12 molded of wood pulp and wherein said end and side walls are of bowed construction, said primary ribs extending generally parallel to said side and end vails and joining to form generally rectangular open windows.
14. A tray in accordance with claim 12, further comprising secondary ribs extending across said gutter-like bottom wall to said end and side walls, said secondary ribs having a height substantially equal to said primar ribs and being staggered in relation to said primary ribs, said primary and secondary ribs having an included V-angle of about 10°.
15. A trjty in accordance with claim 13 further comprising secondary ribs in line with said primary ribs extending across said gutter to intersect said end and side walls at a level substantially above said rib height.
16. A tray in accordance ith claim 14 wherein said primary and secondary ribs have an included V-angle of about 10°.
