Abstract: This invention relates to a container which is folded from a flat blank of material being provided with a plurality of fold lines forming a bottom wall, side walls and top wall panels in the blank. The side walls are coupled to one another by bellows-type coupling members which are adapted to be inwardly folded during assembly to draw up the adjacent side walls to which there are attached. The top walls are dimensioned such that upon folding into a substantially parallel relationship with the bottom wall will form a closed container which is especially suitable to be used as a gift box or the like. A portion of the bellows-type coupling member may be non-structurally adhered to a side wall of the container acting to greatly enhance subsequent folding and assembling of the container into its finished form. Predetermined fold lines may be pre-folded to allow more convenient assembly, which still enable packaging and handling of the container in a substantially flat form as desired.

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 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.
