Appeal No. 2001-1387
Application No. 08/715,210
a) a reusable liner portion;
b) an inner seal portion;
wherein the reusable liner portion is sized to fit
within a closure for a container and the inner seal acts as a
seal on an opening of the container, the improvement
comprising
i) a pressure sensitive light tack shearable adhesive
joining one face of the reusable liner to an opposing face of
the inner seal, said adhesive more readily failing in shear
than said reusable liner portion so as to enable separation of
the reusable liner from the inner seal; and
ii) a polyolefin layer as part of the reusable liner.1
THE EVIDENCE
The items relied on by the examiner as evidence of
obviousness are:
Helms et al. (Helms) 4,418,834 Dec. 6, 1983
Peeters 5,381,913 Jan. 17, 1995
Finkelstein et al. (Finkelstein) 5,598,940 Feb. 4,
1997
Unipac, “Induction Seal - ISPE/PP-WD” June 21, 1991
1The references to the “inner seal” and/or “reusable
liner” in claims 1, 3 and 13 through 15, and to “the
polyolefin foamed layer” in claim 12 lack a proper antecedent
basis. Also, the language in claim 9 is inconsistent as to
whether the heat resistant polymeric layer is a part of or
separate from the polyolefin layer. These informalities are
deserving of correction in the event of further prosecution
before the examiner.
