Appeal No. 2004-1333
Application 09/969,190
for refrigeration purposes, said housing/container comprising a
shaped, thermoplastic, substantially gas and water impermeable
outer cladding on the outer surfaces of the container, and a
shaped, thermoplastic, substantially gas and water impermeable
inner cladding on the inner surfaces of the container, each of
said claddings being a portion of the plastic film envelope or
bag (115) used in forming the thermally insulated
housing/container (90), said inner and outer claddings forming a
substantially vacuum-tight interspace therebetween, and an
evacuated thermal insulation (92) filling said interspace.
As can be readily seen in Figures 5-9 of Wynne, and
discerned from the disclosure thereof at pages 5-6, the inner and
outer claddings are clearly “shaped” during the formation of
housing/container (90) as portions of the plastic film bag (115)
are sucked or pulled down into the open end of the foam box (92)
and against the outer walls of the box and into grooves (96)
formed in the walls of the box. Appellants’ line of argument on
page 8 of the brief appears to address pre-forming or pre-shaping
of the inner and outer cladding panels to provide a degree of
form stiffness and stability to such panels prior to assembly of
the refrigeration housing or appliance, however, the broad
