ABSTRACT:
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 by initially folding. The joining members are folded inwardly thereby drawing up the respective side walls to which they are attached. The container does not utilize tabs, glue or other fastening arrangements 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.
