Definitions

  • the primary object of the present invention is to provide a novel display tray which includes a construction facilitating uniform stacking; obviates inward side wall defiection on the lower or female end of a stack of trays due to stack weight; provides uniform nesting; substantially frees the trays to facilitate denesting of the trays manually or by means of mechanical apparatus.
  • Another object of the present invention is to provide in a generally rectangular, low walled display tray the structure affording a constant stacking interval between intermediate side wall flange portions facilitating denesting in autornaitc denesting equipment and facilitating efficient hand-denesting, and maintaining dimension control, particularly with respect to the corner portions of the molded tray.
  • FIG. 1 is a top plan view of a tray including the features of the invention
  • FIG. 2 is an end elevation looking from right to left at FIG. 1;
  • FIG. 3 is a side elevation looking at the lower edge of FIG. 1;
  • FIG. 4 is a side elevation, similar to FIG. 3 and showing a plurality of the trays in nested relationship;
  • FIG. 5 is an enlarged fragmentary perspective view looking into the upper right-hand corner of the tray of FIG. 1;
  • FIG. 6 is an enlarged fragmentary vertical section taken substantially on the plane of line 66 of FIG. 1; and showing generally how the modified corners merge into the intermediate adjacent peripheral tray flange portions;
  • FIG. 7 is a fragmentary enlarged vertical section taken substantially on the plane of line 7-7 of FIG. 1;
  • FIG. 8 is an enlarged fragmentary vertical section showing a plurality of nested trays in sections similar to FIG. 6, and indicating graphically the denesting interval between adjacent or overlying intermediate peripheral flange portions of the nested trays;
  • FIG. 9 is an enlarged fragmentary vertical section showing a plurality of nested trays in section similar to FIG. 7.
  • a molded pulp tray is indicated generally at 10, the tray generally comprising the type described as a display tray eventually used for the purpose of packaging meats, fruits, etc.
  • the tray is produced by means of conventional methods familiar to those skilled in the art.
  • the tray 10 comprises a substantially planar and rectangularly conformed bottom wall 12 bordered by upwardly and outwardly extending side walls 14 and 16 and end walls 18 and 20, and adjacent walls are connected by arcuate, upwardly and outwardly extending corners 22.
  • the walls 14-20 as well as the corners 22 are integral with an outwardly and downwardly angled peripheral marginal flange 24.
  • the flange portions bordering side walls 3,220,631 Patented Nov. 30, 1965 14, 16 and 18, 20 and corners 22 are respectively identified at 26, 28, 30, 32 and 34.
  • the side walls 14, 16 and end walls 18, 20 terminate in a substantially linear upper edge 36 and 38, respectively, which are substantially coplanar, i.e. falling generally within a common horizontal plane parallel to the bottom wall 12.
  • a transversely, or vertically thickened denesting portion or abutment 40 terminating above the upper edges 36 and 38 clearly seen in FIGS. 2-8.
  • the thickened portions 40 comprise an arcuate lip which merges into the adjacent side edges 36 and 38, and as seen in FIG. 4, and dramatically illustrated in FIG. 8, forms a spacing or denesting interval 42 between adjacent trays which are nested.
  • transversely thickened, denesting portions have thereat a vertical angle with the bottom which differs from that at the intermediate peripheral flange portions of the tray, and in this manner minimum frictional contact between adjacent portions of nested tray walls is controlled. Since certain portions are maintained substantially out of nested contact, denesting or separation of the individual trays is facilitated.
  • the angle of the corners 22 with respect to the bottom wall 12 is between 18 to 28 degrees as compared with a similar angle through the midpoint at the side walls 14-20 which is about 28 to 32 degrees; see FIGS. 8 and 9.
  • the corners are the load bearing portions of a nested stack of trays and the side walls are substantially non-load bearing.
  • This angular relationship of the side walls and corners together with the thickened portions 40 cooperate to provide a corner loaded stack which can be readily denested.
  • dimension control of the tray is improved and dimension changes during drying and shrinkage are accurately controlled.
  • tray of the invention facilitate separation or denesting, but this tray enhances package production inasmuch as it lends itself to use on automatic denesting apparatus as well as manually operated denesting apparatus.
  • a rectangular, molded display tray comprising:
  • said side and end walls including a peripheral marginal flange including an upper edge portion disposed in coplanar relation in a common upper plane, the improvement comprising, at least,
  • each of said abutments are located at the corner of said tray flange.
