Interference No. 103,640
the strip are attached to the film forming a broad area of
attachment for a strong bond. Ausnit differs from the subject
matter at issue in the interference only to the extent that the
upper webs 20a and 21a are not unitary but are fastened together
as the bag is sealed forming a fin seal at 24 which must be
severed by the user to gain access to the content of the formed
and filled bag.
Ausnit ‘787 discloses a fastener strip for a reclosable
bag. As shown in Figures 4, 5 and 6, the strip has two inter-
locking members 44 and 45 so that when the sheet is folded the
interlocking members face one another. The strip further
includes web portions 47 and 48. The two interlocking members
are joined together by a unitary central strip or web 46 which
makes the strip, the webs, and the interlocking members an
integral unit. When applied to the mouth of a bag, the
interlocking members are interengagingly sealed and the central
strip forms a folded seal outwardly of the interlocking members
that must be removed, as shown in Figure 6, to gain access to the
contents of the bag. Ausnit ‘787 differs from the subject matter
of Inagaki’s involved claims in that Ausnit ‘787 has no
disclosure of a form, fill, and seal machine. This patent is
directed only to the sealing strip configuration and its method
of use.
