  • Patent number: 4979666
    Abstract: An articulated tray apparatus for describing a shallow depth container for use on conveyor packaging lines, capable of retaining loose piece-part objects deposited therein, and constructed in a manner to permit formation of the container by automated trayformer-carton erection equipment as well as to permit facilitated closure of the apparatus after filling. At least two opposite side walls and respective top panels are joined, upon articulation of the container blank, to at least two opposite end walls and respective end panels, by connection flaps which have upper and lower portions connected to one another. The upper portion of the connection flaps each contain an articulation fold line for facilitating articulation and closure of the connection flaps, while relieving resistance upon closure and sealing of the container.
