Appeal No. 96-3690
Application 08/234,516
ANTICIPATION BY ISAKA
The examiner rejected claims 14-16 and 18 under 35 U.S.C. § 102(b) as being
anticipated by Isaka. On pages 1 and 2 of the specification, appellants summarize their
invention as follows:
The invention relates to the packaging of a product capable of absorbing
unwanted odors and unpleasant flavors, or a product containing desirable flavor
and aroma characteristics, that are to be retained. The package employs an
oriented film of a blend of polypropylene and a member selected from the group
consisting of polymerized d-limonene, polymerized beta-pinene, or a
polymerized synthetic approximation of d-limonene and beta-pinene and
mixtures thereof, to exclude unwanted odors or flavors and to retain those that
are desirable. The present invention is also concerned with a method for
preventing the transmission of odors and flavors into or out of a product, when
the product is packaged in an oriented film of a blend of polypropylene and a
member selected from the group consisting of polymerized d-limonene,
polymerized beta-pinene, and polymerized synthetic approximation of d-
limonene and beta-pinene and mixtures thereof.
It is preferred that the film structures identified above include a heat-
sealable skin layer comprising a polyolefin of comparatively low stereoregularity
on at least one surface thereof.
The subject matter recited in claim 14 is directed to a method of sealing a product with
a film comprising "an oriented film of a blend of polypropylene and a polymerized polyterpene
selected from the group consisting of polymerized d-limonene, polymerized beta-pinene, and
mixtures thereof, said polyterpene being present in an amount sufficient to act as an effective
odor and flavor barrier when blended with polypropylene.” Thus, the oriented film, as defined
in the claim, has the property of acting as a barrier for preventing the transmission of odors
and flavors into or out of a product.
