ABSTRACT:
A composite tray and stacker structure for packages of a plurality of identical paperboard and/or plastic containers supported in a tray for the purpose of providing compressive load-bearing capability to the package. The composite tray and stacker is composed essentially of a single sheet of stiff material, such as corrugated paperboard. The structure includes a rectangular tray bottom wall having a central transverse reverse fold line and a pair of end walls connected to the bottom wall along fold lines. A pair of top wall spacer elements are foldably connected along the top edges of the end walls and a pair of weight-bearing abutable stacker elements are foldably connected to the spacer elements. A relatively narrow product retainer panel is connected to each of the side edges of each of the end walls and stacker elements along fold lines and fastening tabs are connected along fold lines to each end of the retainer panels. In the assembled package the end walls and spacer elements lie in parallel spaced apart relation to support packages stacked one on another. The tabs of the retainer panels engage the outer surfaces of the bottom tray and top wall. The assembled package encloses a pair of mirror image cells or compartments for product containers and is readily divisible into half packages.
