  • Patent number: 5361975
    Abstract: A shipping tray fashioned from a unitary blank of corrugated paperboard or the like and which is particularly adapted for the packaging of strawberries. The tray is provided with a separable longitudinal divider, also fashioned from a unitary blank of corrugated paperboard. The end structures of the tray are so formed that each tray end presents a slanting surface, with the divider panel also exhibiting a pair of opposed slanting surfaces. The slant of all of these surfaces fairly conforms to the slant of a conventional strawberry tray, to thereby minimize looseness of the strawberry trays in the tray of this invention. The divider panel, not being integral with the tray, need not be used. However, if used, the divider is easily inserted and taken out manually. Upstanding tabs at the tray ends are adapted to be received and fit into complementary recesses in the tray bottom, so as to thereby assist in aligning the trays when they are vertically stacked.

  • Patent number: 4159797
    Abstract: A tray and blank therefor constituting a shipping container with two or more open top compartments separated by a divider especially constructed to act as a strut to rigidify the tray and to support the central region of the bottom wall of the tray against bulging or sagging. The divider includes a horizontal top panel and a pair of integral vertical flaps all extending from side to side of the tray and the pair of vertical flaps also extending from fold lines along the edges of the top panel downwardly to the bottom panel thus forming a rigid hollow strut of rectangular cross section. Glue flaps integrally formed in the bottom panel are bent upwardly along spaced parallel lines into vertical planes and are adhesively secured to the inner surfaces of the vertical divider flaps inside the divider or strut.
