Abstract
Abstract A system of packaging sets of thread cutting dies which are used in pipe and bolt threaders or the like, the system including a display cabinet holding a plurality of die packages without the necessity of having to provide a compartment in the cabinet for each of the die packages. The die packages comprise a one piece box and a top removably fitted on the box. In order to package a wide range of sizes of die sets in the minimum number of boxes, the outside dimensions of the box remain fixed so that the packages can be utilized in the display case and various supports for the die sets are provided internally within the boxes so as to hold various sizes of die sets in position within the box without substantial vertical, lateral or longitudinal movement of the die set relative to the box. The box and the lids are so structured that when the boxes are stacked on one another in the display cabinet, horizontal movement of the stacked boxes relative to one another is prevented.

A system for packaging one or more machine tool parts, such as thread cutting dies or the like, comprising a plurality of packages, each package comprising a generally rectangular container having a bottom wall, an end wall at each end of the bottom wall, and a side wall at each side of the bottom wall, the top of the container being open, and a lid for closing the open top of the container, the upper edges of said side walls and the bottom of said lid having dovetail tongue and groove means so that upon said tongue and groove means being engaged with one another, the lid is slidable in a direction generally parallel to the bottom wall of the container from an open position in which the lid is substantially clear of the open top of the container to a closed position in which the open top of the container is closed by the lid, the upper face of the lid and the bottom face of the bottom wall of the container of said packages of the said packaging system having means thereon for at least partially interlocking the bottom wall of the container of an upper package with the lid of the lower package when two or more of the packages are stacked vertically, said package interlocking means comprising receptacle and protuberance means on the container bottom wall and on the lid with the protuberance means of one package being received in the receptacle means of another package, said interlocking means preventing sidewise, endwise, and rotational movement of one stacked package relative to another, wherein said receptacle means comprises two generally U-shaped ribs extending out from the bottom surface from the bottom wall of the container with the bases of said U-shaped ribs being parallel and transverse to the sides of the container with these bases of the U-shaped ribs being spaced apart from one another, and wherein said protruberance means comprises a generally H-shaped rib formed on the upper surface of the lid with a cross rib of H-shaped protruberance rib being received between the parallel bases of the U-shaped rib of the receptacle means and with the inner faces of the H-shaped rib being engageable with the outer faces of the U-shaped receptacle ribs thereby to prevent lateral, longitudinal and rotational movement of one stacked package relative to another.
