Definitions
- the present invention relates to an open bottom food container and, more particularly, to a food container for use for the packaging of meat, poultry and fish in conjunction with a plastic overwrap film and where the bottom wall is replaced by a plurality of open windows.
- Molded wood pulp food trays have served the food packaging industry well for many years for the packaging of meat, fish and poultry.
- Such trays have the advantages, besides low price and low cost to the consumer, of being clean, sturdy and safe, of being biodegradable so as to minimize the solids pollution problem, and of being capable of controlling the liquid and juices which exude from meat, fish and poultry.
- FIG. 1 is a front elevation, partly broken away of a meat packaging tray in accordance with the present invention
- FIG. 2 is a perspective view looking into the interior of the tray of FIG. 1;
- FIG. 3 is a bottom view, looking up, of the tray of FIGS. 1 and 2;
- FIG. 4 is a front elevation, partly broken away, showing a second embodiment of a meat packaging tray in accordance with the present invention
- FIG. 5 is a perspective view looking down into the interior of the tray of FIG. 4;
- FIG. 6 is a bottom view, looking up, of the tray of FIGS. 4 and 5.
- a food packaging tray 10 is shown in FIGS. 1-3 for the packaging of meat, fish or poultry in association with an overwrap film of plastic or heat-sealable cellophane.
- the food tray 10 is provided, as is conventional, with four upwardly and outwardly inclined sidewalls 12, 14, 16 and 18, each being joined to adjacent walls by a rounded portion 20.
- Each sidewall and the intermediate rounded portions are provided at their terminal portion by a downwardly and outwardly inclined bead or flange 22.
- the tray 10 is provided with a plurality of ribs 24 extending between the bottom of the wall portions 14 and 18, and, at right angles thereto, a plurality of ribs 26 extending between sidewalls 12 and 16.
- these ribs form in cross-section an inverted V-shape, and terminate at their upper portions, forming the bottom of the tray, in the apex of the V.
- the bottom 25 of the V-shaped ribs 24 and 26 terminate adjacent the bottom 21 of the sidewalls. Accordingly, it will be seen that the sidewalls terminate in a plane which also passes through the bottom of the inverted Vs as best shown in FIG. 1, in that the actual bottom of the tray upon which the meat, fish or poultry rests corresponds to a height above the bottom termination plane of the sidewalls.
- the support provided by the bottom of the tray is in the form of a plurality of line contacts which occupy a minimum contact area.
- the top of the package is free for inspection of the food packaged which is normal.
- approximately -95 percent of the total packaged contents will also be visible through the separate windows between criss-crossing ribs 24 and 26 and the top of the tray. The inspection of the bottom of the food is improved by tiping the package and sighting through the windows in a direction parallel to the walls of the rib.
- the key features of the invention are provided by forming the cross ribs 24 and 26 of an inverted V- shaped cross-section.
- the V-shape not only provides maximum strength preventing inward collapse of the sidewall upon tight overwrapping of the package, but the inverted V-shape permits maximum visibility, as pointed out above, through the open window and also provides the added advantage of denesting to improve ease of separatability of adjacent trays subsequent to shipping and prior to filling and packaging.
- the tray isformed of wood pulp as is preferred, it is also capable of controlling exuded liquids preventing such liquids from puddling to impair visibility and other-wise affect the keeping qualities of the tray contents.
- FIGS. 4-6 A second embodiment tray is shown in FIGS. 4-6.
- the tray 100 is provided with four sidewalls 120, 140, and 180, a peripheral flange 220 and bottom ribs 240 and 260, having inverted V-shaped cross-sections, which intersect at right angles to form rectangular windows.
- Tray 100 differs from tray 10, however, in that the bottom of the sidewalls 120, etc., terminate at the top, rather than the bottom, of the inverted V-shaped ribs 240 and 260.
- the sidewall terminates at its bottom edge 181 in a plane passing through the apex of the inverted V-shaped ribs 240 and 260.
- the bottom edge 141 of the sidewall 140 and the bottom edge 121 of the sidewall 120 terminate in the same plane.
- the sidewalls are provided with downwardly depending portions 122, 142, 162 and 182.
- the food tray of the present invention offers visibility to those consumers who desire it, while maintaining many of the advantages of the solid molded pulp food packages.
- the consumer has the option of using the solid bottom or visible bottom tray that will best serve his wants in properly packaging the food product it will contain.
- a molded tray for the packaging of meat, fish or poultry in conjunction with a transparent overwrap film heat-sealed thereabout, said tray comprising at least one upwardly and outwardly inclined substantially imperforate sidewall defining the peripheral extent of said tray, the improvement comprising bottom wall means for providing approximately -95 percent visibility of the package material and simultaneously supporting the meat, fish or poultry, said bottom wall means comprising a plurality of substantially opaque ribs having an inverted V-shaped cross-section, said ribs extending across said tray in at least two directions at angles and intersecting to define therebetween wholly open areas comprising a plurality of open windows.
- a molded tray in accordance with claim 1 formed of wood pulp.
