Abstract: A container assembly which is especially adaptable to form a final presentation enclosure is constructed from a flat blank of material, optionally having fold lines delineating a bottom, side, and top wall portions which act in conjunction with one another to enclose a space. The side walls may be connectable by joining portions constituting bellows-type folding members. From flat, the container is constructed by folding. Joining members are folded inwardly thereby drawing up respective side walls to which they are attached. 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.

Abstract: In accordance with a broad embodiment of the invention, a novel paper product is comprised of two or more slit sheet packing material layers, each layer having its own slit pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. Adjacent layers have differing slit patterns and can be expanded through expander type machinery such that the expansion rates of the differing slit pattern layers can be varied to deliver the same width of exiting expanded material from each layer. Preferably the differing slit pattern produce when expanded, inclined land areas that have the same number of rows per inch, but different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.

Abstract: The Present Invention discloses a slit web material, substantially longer than it is wide, with specially shaped slits that permit relatively easy expansion upon deployment. The specially shaped slits are referred to in the Present Application as “tilde-slits,” because they resemble a tilde mark. The cuts are arranged in continuous rows of tilde-slits. In any given row, the tilde-slits follow one-after-the-other in a linear direction. Adjacent rows of slits are parallel to each other, but are offset from one another such that a line drawn between adjacent tilde-slits in adjacent rows is not perpendicular to the direction of the rows. The invention contemplates that the material dispenses from a continuous roll. If the slits are arranged in the longitudinal direction, then the web material expands in the width direction only upon deployment.
