Definitions

  • the present invention is directed to a carrier tray for supporting items such as beverage containers and more particularly to a tray designed to prevent relative movement between adjacent trays when two or more trays are aligned vertically, e.g., when they are stacked or nested.
  • Another problem associated with carrier trays relates to deformation of the underside (i.e., "doming") of a beverage can stored on the tray, which may render it unsalable because the subsequent leaning, denting or abrasion of adjacent cans by a domed can could destroy the domed can or its "neighbors". If such doming or abrasion or denting results in spilling beverage, all remaining cans under certain regulations could become unsalable, causing severe loss to merchants.
  • US-A-3 281 010 shows an article carrying case in which the bottom section of each receptacle area has raised ridges which helps position the bottles in the cells and to strengthen the case, but not to prevent doming.
  • US-A-4 040 517 (Torokvei) describes a stacking case with upwardly projecting support members for carrying a number of bottles in each section of the case. These support members center the bottle in the cell and provide support for the bottles.
  • US-A-3 333 729 (Rabb) describes a bottle carrier with dividers in which the bottom side of each section extends upwardly creating a protrusion which fits under the similarly shaped underside of the bottom of the bottle stacked above it and houses the cap area of the stacked bottles below it.
  • This patent also does not address "doming" prevention.
  • US-A-3 283 947 (Cornelius) reveals improvements to a bottle carrier for transporting, handling and storing crowned-cap beverage bottles in a container molded from suitable plastic material such as high-density polyethylene.
  • Figure 5 shows each cell of the carrier having a "centrally upwardly offset, preferably circular portion 19 connected with the normal plane of the base wall by means of a reinforcing offset tapered generally annular flange 20". Like the Torokvei and Rabb patents, this patent does not address "doming" prevention.
  • US-A-3 203 583 shows a tray for cups filled with drinks, in which the compartment portions have "upward protruding portions" 22 at the underside of each cup receiving socket.
  • the purpose of such protruding portions is to "permit air passage" to underlying stacked drink cups and presumably to prevent excessive lateral movement of the cups.
  • US-A-4 142 634 (Leff) is directed to a separator for supporting stacked layers of containers having a plastic section with a honeycombed pattern embossed on its top surface for rigidity.
  • the separators include "interior portions" which centrally position spools of yarn 15, 16.
  • Yet another object of the invention is to create a can-carrying carrier which will also prevent abrasion of the can or neighboring cans.
  • a further object of the invention is to construct a can-carrying carrier which will prevent denting of the can or neighboring cans.
  • An additional object of the invention is to impede leaning of a can against a neighboring can or against a carrier wall.
  • Still another object of the invention is to create a carrier of sufficient strength to carry a large number of cans without cracking, breaking, or deforming.
  • a tray for supporting a plurality of items such as beverage containers includes a base having a surface for supporting the items and at least one side wall extending around a substantial portion of the perimeter of the base.
  • the side wall has upper and lower spaced surfaces, each of the surfaces of the side wall substantially parallel to the surface of the base.
  • the tray includes a projecting member extending from one of the surfaces of the side wall, and a recess formed in the other of the surfaces of the side wall, the recess positioned to receive a projecting member of a second similarly constructed tray located vertically adjacent to the first tray.
  • This mating of the projecting member and the recess of two vertically adjacent trays prevents the walls of the trays from moving laterally with respect to each other, thereby preventing the weight of the stack from causing the lower trays to flower or deform, reducing damage to the trays and preventing the stack of trays from becoming unstable.
  • the tray includes four side walls and the base is substantially rectangular.
  • the tray includes two projecting members, each of which extends upwardly from one of the side walls, and two downwardly opening recesses positioned to receive each of the two upwardly projecting members of a second similarly constructed tray located below and adjacent to the first tray.
  • the base comprises a plurality of areas, each of which is designed to support one deformable container, and an upwardly projecting member extending from each of the areas on the base, each member downwardly tapered to conform to the shape of the bottom surface of a container supported on each area, thereby preventing the container from deforming.
  • Each area also includes a second upwardly projecting member intersecting and substantially perpendicular to one of the first members.
  • Each of the side walls of the preferred tray comprises an upper rail and a plurality of ribs extending from the base to the upper rail, with the projecting members extending upwardly from one of the ribs.
  • the tray also comprises an upwardly projecting ridge extending from the base and positioned to be against the outer perimeter of a container supported on the base to prevent leaning of the container.
  • FIG. 1 shows carrier 1 generally comprising base 50 circumscribed along its periphery by side walls 10, 20, 30 and 40.
  • the side walls generally include a uniform series of upwardly projecting ribs or stems 11.
  • each stem 11 comprises three segments, including extreme segments 12, 13 which are shaped in a curved fashion to conform to the shape of the containers which are to be transported in carrier 1.
  • Positioned between extreme portions 12, 13 is central portion 15.
  • the walls 10, 20, 30 and 40 also include curved portions 21 between straight portions 200 (see Figure 5) between adjacent stems 11 to thereby conform to cylindrical items such as cans which are to be placed in carrier 1.
  • a portion of base 50 of carrier 1 is depicted in Figure 2, and generally comprises north/south ribs 51 and east/west ribs 52 defining rectangular areas 53.
  • the transported containers 70 (see dashed outline in Figure 2) are centrally positioned on each rectangular area 53.
  • Each area 53 has, in each of its four corners, circular "disks" 54, 55, 56 and 57 and an inner ring 58.
  • Intermediate north/south ribs 59 and east/west ribs 60 are respectively perpendicular to east/west ribs 52 and north/south ribs 51, and extend from the center of the edge of each rectangular area 53 into inner ring 58.
  • Diagonal ribs 61 extend from each corner of each rectangular area to inner circle 58.
  • a half-moon structure 80 is built on carrier base 50 as a part of inner ring 58 to help prevent leaning of the beverage container in the carrier 1.
  • the half-moon structure 80 may be used independently of the anti-doming segments 62, 63 or in conjunction with them.
  • a delivery person attempts to remove the top carrier 1 from a stack of carriers, there is normally a tendency to tilt the container 70 (See Fig.8) on the leading edge creating a force in the direction of force line F on the edge of the top of the cans in the next lower tray(s). That force is frequently sufficient to displace the can from the lower tray, particularly if the tray is a low depth type.
  • the half moon 80 will prevent this occurrence by creating a reactive force in the direction of line R.
  • stem 101 has an integrally formed upwardly projecting member 102 that is generally U-shaped, and includes a pair of upwardly projecting points 121 and 131 that extend beyond the upper surface 109 of side wall 106.
  • Fig.12 is a view of the side wall segment shown in Fig.11 from the opposite direction.
  • Side wall 106 also includes a downwardly extending recess 140 which is formed between the rear surface 112 of side wall stem 101 and the inner surface of side wall 106.
  • Side wall stem 103 and upwardly projecting member 104 are constructed similarly to side wall stem 101 and upwardly projecting member 102 illustrated in Figs.11-12. Similarly, a second downwardly opening recess 142 (see Fig.10) is formed between stem 103 and the inner surface of side wall 108.
