between each planar wall 24 and the adjacent facing sheet
26 or 27 and thus serves to further define and reinforce the
included angle between the planar walls 24 of any given
flute.
George points out that the sharp folds of the inventive material are an
improvement over undulated corrugated material because they result in flutes which are
truly flat and planar and therefore maintain their inherent strength and resist stress and
deformation and discloses that “[a]n important field, yet by no means the only field for
utilizing the new article of manufacture, is for all of the purposes for which the known
corrugated paperboard formed with undulating or sine-like curved corrugated medium is
employed” (column 6, lines 70-74) and goes on to discuss boxes and shipping
containers and refers to the “novel container board of the invention” (column 7, line 12).
The examiner concedes that George lacks, inter alia, the at least one facing sheet 26,
27 being tissue paper, as required in each of independent claims 1, 19 and 26.
Thiebaut discloses a packing box or case comprising cardboard a folded at acute
angles, which enables it to resist pressure far better than the undulated cardboard
material used in the prior art discussed by Thiebaut on page 1, in lines 11-23, with
“cardboard, paper or any thin fabric” b pasted on one or both sides to prevent the folds
from becoming flattened or widened at their bases (page 1, lines 43-46). Thiebaut thus
obtains a covered and ribbed compressible or extensible sheet of cardboard applicable
not only to the purposes for which similar cardboard has been used, but also for the
