Arvidson discloses a “multi-layer co-extrusion blow molded
plastic container adapted to be filled with a heat-sensitive
nutrient and then retorted at relatively high temperatures to
sterilize the contents thereof” (Abstract). The multi-layered
wall structure of the container
is characterized by inner and outer layers 34 and 36
both of which are of a food-grade polypropylene having
a minimum thickness of 0.002 inches, a regrind layer 38
adjacent the outer layer 36, a pair of high temperature
adhesive layers 40 and 42, such as 0.0015 inch
polyolephin [sic, polyolefin] disposed adjacent the
regrind layer 38 and the inner layer 34, respectively,
and, between the two high temperature adhesive layers
40 and 42, an oxygen barrier layer 44 of ethyl-vinyl-
alcohol (EVOH) having a thickness of from 0.0015 to
0.002 inches [column 3, lines 8 through 18].
Baird discloses a “multi-layered, handled plastic bottle

outer appearance of the bottle can be enhanced by including
opacifying pigments, such as carbon black, titanium dioxide
(TiO ) or a ferrous oxide, in the outer layer of the bottle (see
