(57) A packaging tray A primarily for gable-top containers 7 has a rectangular base 1
with a flat upper surface 2 and an underside with projections 5 forming parallel channels
6 within which the tops of the containers 7 carried on the upper surface of an underlying
similar tray B are received in complementary manner. Wall parts 8 extend upwardly
from edges of the base 1 to retain the containers on the base and opposed wall parts
13, 14 extend downwardly from edges of the base 1 to overlie the ends of the channels
6 to retain the tops of the containers 7 from sliding through the channels. Two trays
can be stacked when empty by the lower edges 16 of the walls 13, 14 of the upper tray
standing on the upper edges 17 of the walls 8 of the lower tray.
