A collapsible shipping container formed on a supporting pallet and made up of a base and cover tray, separator members and rectilinear partition tubes, all made of sheet material such as corrugated paper. The separator members are made up of a pair of trays fixed to each other to form a cover for a lower layer of partition members and a receiving tray for an upper layer of partition members. All of the sheet material elements are foldable for stacking in a folded condition in the order in which they are used for movement as a unit to the packing area where packing is accomplished by removing layers of the folded components in the order of which they are used to erect an interlocked shipping container in which the various layers of material resist shifting relative to each other.
