Interference No. 103,640
Finally, Ausnit ‘443 is directed to another fastener
strip for a reclosable bag. The strip has interlocking members
20 and 21 on webs 16 and 17. Outwardly of the interlocking
members, flanges 25 and 26 are provided with a line of frangible
connections such as spot welds 27 in the Figure 1 embodiment, or
a seam 40 with holes 41 therein in the Figure 6 embodiment.
Thus, the strips of Ausnit ‘443 are unitarily connected when
formed (see Figure 5) and then applied to a bag.
It is our further finding that Ausnit ‘787 is evidence
of a recognition in the art of the self-evident advantages
possessed by the folded integral fastener strip disclosed
therein. Foremost is the advantage that the two interlocking
member strips as disclosed in Ausnit ‘787 cannot be misplaced one
from the other while in transport or when feeding in the form,
fill, and seal machine. The strips of Ausnit ‘787 are integrally
connected, and so one interlocking member necessarily carries its
complementary member nearby.6 Secondly, it is self-evident that
the folded strip of Ausnit ‘787 at the folded edge 54 has a neat
and tidy appearance as compared to the two flattened laminated
layers of the fin seal of Ausnit ‘533. Thirdly, although the
‘787 patent shows two lines of perforation 49 and 50 for ease of
6 The strips of Ausnit ‘443 also possess this self-evident
advantage.
