Application No. 08/887,648
cohesively sealing limitations of claims 13 and 18 are met by 2
Charbonneau. Charbonneau also teaches (column 3, line 62, to
column 6, line 13) that the volatile liquid containment
treatment 54 is a polyvinyl alcohol containing a crosslinking
agent which is coated and dried onto the paper substrate sheet
52. In our view, this forms "a film barrier." Thus, the film
limitations of claims 13 and 18 are met by Charbonneau.3
Based on our analysis and review of Charbonneau and
claims 13 and 18, it is our opinion that the only difference
is the limitation that "a liquid fragrance" is utilized rather
2In claim 13 the limitation is "cohesively sealing the
barrier to itself to form an enclosed pocket which
encapsulates the sample, said sealing being accomplished
without the use of pressure sensitive materials." In claim 18
the limitation is "said first and second portions of the
barrier being one of heat, adhesive, and cohesively sealed
around said fragrance sample to hold said first and second
portions of said barrier together and to substantially prevent
the premature release of said liquid fragrance from said
sample, until said carrier is pulled open to provide for
release of the liquid fragrance from the carrier."
3In claim 13 the limitation is "applying a film barrier
to said carrier." In claim 18 the limitation is "one of a
film barrier and coating applied to one of the first and
second halves of the carrier adjacent its fold line for
reception of the fragrance sampler and to prevent its
migration and wicking into the said carrier."
