Appeal No. 97-0608
Application 08/287,143
relatively small pieces of material (e.g., polystyrene "pea-
nuts," shredded paper, or popcorn) used to fill the empty
space around a packaged item in a package and to cushion the
product or item and prevent movement of the item during ship-
ping and handling. This type of
fill material is also sometimes referred to as "dunnage." The
void fill material of the present application is derived from
sheet material, such as corrugated cardboard. More specifi-
cally, it is explained on page 7 of the specification that
[t]his invention provides for the easy
conversion of sheet material into a void
fill material having interlocking members.
The cardboard material is cut by the cutter
and anvil cylinder arrangement wherein the
interlocking members of the void fill mate-
rial are formed by the cutting blades on
the cutter cylinder.
The sheet material, such as corrugated
cardboard, is environmentally safe as op-
posed to void fill material containing
CFCs. By recycling cardboard or sheet
material through the present invention, the
cardboard or sheet material will not be
placed in landfills thereby providing an-
other beneficial environmental impact.
Corrugated void fill is easy to create,
