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.

Claims (18)
1. In a generally rectangular molded tray for the packaging of fresh meat, fish or poultry in conjunction with a transparent overwrap film heat-sealed thereabout, said tray comprising a pair of upwardly and outwardly inclined 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 configuration 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 providing improved oxygen breathing through the bottom of the tray and for providing visibility through the bottom of the tray and for supporting the meat, fish or poultry at the bottom of said tray while maintaining a high humidity thereabout substantially without the formation of liquid pools, and also for protecting meat freshness and improving meat quality maintenance, said breathing and support means comprising a plurality of strong, substantially solid primary ribs having an inverted V-shaped cross-section with rounded apices, some of said primary ribs extending in one direction, and other of said primary ribs extending in a different direction, said primary ribs meeting and defining therebetween a plurality of open windows, said ribs having 40355/ 2 a section modulus in combination with said end and side walls such that the total strength is substantially equal to the beam strength of a tray 'of the same material of equal weight with a flat, imperforate bottom; and means to increase rigidity and strength comprising a peripherally extending annular transition zone between said end and side walls and said primary iibs, wherein said annular transition zone comprises a gutter-like bottom wall and secondary ribs extending thereacross, and wherein said secondary ribs are staggered in relation to said primary ribs.
2. A tray in accordance with claim 1 molded of wood pulp.
3. A tray in accordance with claim 2 wherein said end and side walls are of bowed construction.
4. A tray in accordance with claim 2 wherein said primary ribs have a h eight about five times the thickness of said side and end walls.
5. A tray in accordance with claim 2 wherein said primary ribs have an included V-angle of about 10°.
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.
