Appeal No. 2002-0420
Application No. 09/230,776
The invention relates to “a system and method for
triggering oxygen scavenging compositions for use in packaging
oxygen sensitive articles” (specification, page 1).
Representative claims 26 and 32 read as follows:
26. A method comprising:
a) providing an unwind roll, said roll adapted to hold
a roll of oxygen scavenging film, the film comprising an
oxidizable organic compound;
b) providing an apparatus for triggering said film, the
apparatus comprising at least one lamp adapted to emit pulses
of UV light having a wavelength of between 200 and 400
nanometers;
c) advancing the film from the unwind roll to the
apparatus for triggering the film by means of a series of
rollers that define a film path extending from the unwind roll
to the apparatus for triggering the film;
d) passing the film past at least one said lamp;
e) exposing the film to pulses of UV light;
f) advancing the triggered film from the apparatus for
triggering to an apparatus for packaging articles; and
g) applying said triggered film, in the apparatus for
packaging articles, to make packages for containing said
articles;
whereby said triggered film is continuously
triggered and incorporated into said packages so as to provide
oxygen scavenging packages.
32. An apparatus comprising:
