A container assembly which is especially adaptable to form a final presentation enclosure is constructed from a flat blank of material. The flat blank is provided with a plurality of fold lines forming a bottom wall, side walls, and top wall portions which act in conjunction with one another to enclose a space. The side walls are connected by joining portions constituting bellows-type folding members. The container is constructed in accordance with the normal hand movements of a person assembling it, wherein the joining members are initially easily folded inwardly thereby drawing up the respective side walls to which they are attached. The natural grasping movement of the hands is then used to complete assembly. The container does not utilize tabs, glue or other fastening means normally associated with a variety of containers. The top walls are formed so as to be exposed at the top of the container to allow securing of the top wall portions by any suitable means. There is also provided a variable volume container by means of the joining members which extend into the interior of the container. The joining members act to center and protect a smaller item within the container or can be completely moved to make available the total volume of the container.
A manufacturing die utilized to produce a blank of sheet material adapted to be folded to form a container assembly having a bottom wall, first, second, third, and fourth side and top walls wherein said side walls are each positioned along a peripheral edge of said bottom wall respectively and said top walls are positioned on the outer peripheral edge of each of said side walls respectively, each of said side walls being flexibly coupled to the bottom wall by means of a fold line, and bellows-type coupling members being flexibly coupled at side edges thereof to respective side walls by a fold lien and each of said bellows-type coupling members having a fold line which bisects it to allow inward folding of said bellows-type coupling members in assembly of said container wherein said blank is formed by means of a first set of a plurality of slitting rule members positioned to cut said sheet material along the outer peripheral edges of said blank so as to completely sever the blank from a base sheet of material;
