Definitions

  • This invention relates to a packaging tray and is particularly concerned with such trays as are used for the transportation and storage of load bearing packages (such as cartons of milk, soft drink or the like) whereby several similar trays loaded with the packages can be stacked as a vertical column with the trays in spaced relationship so that each upper tray is mounted and supported on the packages carried by the immediately underlying tray.
  • load bearing packages such as cartons of milk, soft drink or the like
  • Trays of the kind described are commonly employed for carrying so-called "gable-top" containers or packages and it has hitherto been proposed, for example in G.B. Patent Specification No.
  • 2,079,256B for such trays to have a base part with a substantially flat upper surface on which the packages are to stand and an under surface which is profiled to provide substantially parallel channels with a cross section corresponding to the shape of the tops of the packages which are to be carried.
  • the profiled under surface of the tray is intended to permit the tray to be located on and supported by the tops of packages carried by a similar underlying tray and, in the case of gable-top containers, with the apical form of the respective package tops being received in the respective channels. It is an object of the present invention to provide a packaging tray of the kind discussed above and by which a vertical stack of several similar trays loaded with packages can be formed with a stable configuration.
  • a packaging tray having a base part with a substantially flat upper surface on which packages are to stand and an underside surface which is profiled to form substantially parallel channels having a cross section substantially corresponding to the shape of the tops of the packages which are intended to be carried on the upper surface; first wall parts extending upwardly from the periphery of the base part for retaining packages on the upper surface thereof and second wall parts extending downwardly from the periphery of the base part at least partially to overlie open ends of the channel adjacent thereto for restraining packages received in those channels from sliding through the channels in a stacked configuration.
  • a second similar tray can be mounted on the tops of the packages of the first tray with those tops received in the channels which are preferably of substantially complementary shape to the tops; in this stacking configuration the two trays will be vertically spaced so that the upper tray is borne by the load bearing facility provided by the packages on the lower tray.
  • the second wall parts extend downwardly from the periphery of the upper tray and overlie the open ends of the channels adjacent thereto, preferably to an extent less than the full depth of those channels, so that the tops of the packages are restrained by the second wall parts from sliding along the channels and thereby a stable vertical stack of similarly loaded trays can be formed.
  • the second wall parts are formed as extensions of the first wall parts. It is also preferred that the lower peripheral edge of the second wall parts directly underlie at least part of the upper peripheral edge of the first wall parts so that several similar trays when empty can be stacked vertically by the lower edges of the second wall parts standing on the upper edges of the first wall parts.
  • the under surface of the base part at the ends of the channels adjacent to the second wall parts can be tapered to be received smoothly and closely within the confines of the first wall parts of the immediately underlying tray and these tapered edges may abut the inner faces of the first wall parts of the immediately underlying tray to stabilise the stack of empty trays.
  • the second wall parts may have associated therewith locating flanges or webs which are intended to co-operate with the first wall parts of a similar underlying tray to provide stability between the empty trays in forming a vertical stack.
  • locating flanges or webs By interconnecting these locating flanges or webs between the second wall parts and the under surface of the tray it is possible to improve the rigidity and load bearing characteristics of the second wall parts.
  • the base part will usually be of a rectangular configuration with the channels extending parallel to a first pair of parallel edges of the base part so that the packages are intended to be loaded on to the upper surface in rows parallel to the first pair of edges.
  • the first wall parts extend upwardly from the four edges of the base part; it is also preferred that the second wall parts extend downwardly solely from the second pair of parallel edges of the base part to overlie the open ends of the channels adjacent to those second wall parts - this latter arrangement facilitates handling of the tray, particularly when several empty trays are stacked as previously discussed, since the underside surface of the base part can be grasped beneath the first wall parts which extend along the first pair of parallel side edges.
  • the tray is constructed as a one piece moulding in plastics material and with the channels being formed by projections in the underside surface.
  • projections will usually be hollow to provide cavities that open through apertures in the upper surface of the base part and accordingly the projections may be provided with ventilation and drainage holes.
  • Each packaging tray is formed as a one piece injection moulding in plastics and has a rectangular base 1 with a flat upper surface 2. Formed in the base 1 is a symmetrically disposed array of apertures 3 which open to cavities 4 of hollow projections 5 that extend downwardly on the underside surface of the base 1.
  • the projections 5 form on the underside of the tray an array of parallel channels 6 which correspond in shape to the shape of the tops of packages 7 which are intended to be loaded on to the surface 2.
  • the packages 7 are in the form of gable-top cartons as are commonly used for milk, soft drink and the like, and accordingly the channels 6 have a substantially apical cross section with each channel being formed from several pairs of opposed projections 5.
  • the channels 6 can have any desired cross sectional shape in accordance with the shape of the tops of the particular packages which are to be carried on the tray.
  • the cartons 7 are loaded to stand on the surface 2 of the lower tray B so that they are similarly orientated and disposed in parallel rows with the ridges of their gable tops parallel to the channels 6.
  • the rectangular base 1 is provided with a substantially continuous peripheral upstanding side wall 8. This side wall 8 also provides a convenient guide for locating the cartons in their rows parallel to a first pair of opposed side edges 9 and 10 of the base 1.
  • the channels 6 extend parallel to the edges 9 and 10 and, as shown in Figure 1, the tray A is stacked vertically above the tray B so that the gable tops of the cartons 7 are received within the complementary channels 6 and the tray A is supported through the cartons 7 in spaced relationship above the tray B.
  • walls 13 and 14 Extending downwardly from the second pair of parallel side edges 11 and 12 of the base 1 are opposed walls 13 and 14 respectively which are conveniently formed as extensions of the upper walls 8.
  • the walls 13 and 14 have a height less than that of the projections 5 and accordingly partly overlie the open ends of the channels 6 which are located adjacent to those walls 13 and 14.
  • the walls 13 and 14 thus serve as abutments to restrain the cartons 7 from sliding longitudinally through the channels 6.
  • vent holes 15 are provided.
  • the walls 13 and 14 may be regarded as extensions of the upper wall 8 and the lower edges 16 of the walls 13 and 14 are located to vertically underlie the upper edges 17 of the wall part 8 with which they are respectively co-extensive.
  • the walls 13 and 14 may be regarded as extensions of the upper wall 8 and the lower edges 16 of the walls 13 and 14 are located to vertically underlie the upper edges 17 of the wall part 8 with which they are respectively co-extensive.
  • the webs or flanges 18 are extended below the walls 13 and 14 and are tapered as shown at 19 in Figure 2 so that they will be received closely within the enclosure formed by the side wall 8 of the immediately underlying tray above the edges 11 and 12 of that tray so that the abutment of the webs or flanges 18 of the upper tray with the wall 8 of the lower tray restrains the two trays from relative displacement in a direction parallel to the channels 6.
  • the tapering 19 of the webs orflanges 18 provides a convenient lead-in for stacking one tray on top of another empty tray.
  • the downwardly extending wall parts 13 and 14 are restricted to the extent of the opposed edges 11 and 12. This permits the underside of the base 1 to be accessible beneath the opposed edges 9 and 10 and provides a convenient position at which the tray can be grasped and lifted from a stack (especially from a stack of empty trays). If required the projections 5 adjacent to and at the mid-part length of the edges 9 and 10 can be rebated as indicated at 20 to provide enlarged and opposed areas or regions on the underside of the base at which the tray can be grasped to facilitate lifting and stacking.
