together to squeeze rolls 6 and then to scoring and cutting rolls not
shown (Campbell 2:1-14).
2. An essential feature of Campbell’s process is that the scoring is done
while the bond between the tapes and the paper is not dry, but is free
to slip when the scoring is done, thereby yielding a blank which is
truly reinforced by a tape that is firmly bonded on both sides to the
paper thereof (Campbell 1:81-91). This is done to address the
problem that a dry bond between the plies is broken when the score
lines are formed, because of the distortion incident to scoring,
separating the paper and the tape and diminishing the reinforcing
effect (Campbell 1:67-80).
3. As illustrated in Figs. 1 and 4, Campbell forms score lines, shown by
lines 9, 9, “necessary to permit erecting of the carton without breaking
the material thereof” (i.e., fold lines), some of the score lines
extending transversely of the reinforcing tapes, shown by dotted lines
8 (Campbell 2:32-34 and 2:45-48).
4. Campbell does not disclose forming the score lines or fold lines so
that a first section of the fold line within the reinforced region is wider
than a second section of the fold line outside the reinforced region and
forming a transition zone between the first and second sections of the
fold line, as required in independent claims 1 and 11.
5. Seufert ‘916 is directed to folding boxes having two overlapping
blanks of differing materials, such as a cardboard material and a
transparent stiff plastic foil (Seufert ‘916, col. 1, ll. 7-10), with
bending lines extending across the overlap (Seufert ‘916, col. 1,
ll. 32-36). The objective of Seufert ‘916 is to address the troublesome
