Abstract
A tray and its method of formation for supporting card-like articles in juxtaposed relation therein comprising a one-piece body of plastic material molded in flat form with a base, a pair of opposite side parts and a pair of opposite end parts. The side parts and end parts are joined to the base by fold lines about which the parts can be upfolded to form side walls and end walls for the tray. The end walls have tabs at their lateral edges and the side walls are formed with slots which receive the tabs when the walls are in upfolded condition. The end walls form an angle with the vertical in the secured position and the lateral edges are engaged between pairs of ribs formed on the side walls.
Claims11
A tray for supporting juxtaposed articles comprising a base, a pair of opposite side parts and a pair of opposite end parts, said base said parts and end parts being made from a relatively thin, one-piece body, said side parts and end parts being upfolded from said base and interlocking means on said side parts and said end parts to lock said side parts and end parts in upfolded position, the articles being supportable in juxtaposed relation on the base, said interlocking means comprising tabs and slots, said tabs being on one of said pair of parts and said slots being provided in the other of said pair of parts, said tabs being engageable in said slots, said tabs and slots being arranged to hold said side parts and end parts in secured, stable relation in upfolded position on said base, said one pair of parts having opposite edges at which said tabs project, said other pair of parts including ribs on opposite, sides of said slots extending parallel therewith and projecting from said other pair of parts for releasably holding said edges of said first pair of parts with said tabs engaged in said slots and blocking relative pivotal movement of said parts.
A method of forming a tray for supporting card-like articles in juxtaposed relation, said method comprising molding in flat form, a one-piece body of plastic material having a base and opposed end parts and side parts, said body having lines of reduced thickness between the base and the side and end parts to form hinge lines thereat, upfolding the side and end parts from the base, and interlocking each end part with the side parts to hold said parts in secured, stable relation in upfolded position on said base, the interlocking of the parts being effected by inserting a tab on one part into a slot in the other part and engaging the edge of said one part between parallel ribs on the other part disposed on opposite sides of said slot.
