Application No. 09/055,377
DISCUSSION
Rejection (1)
Zimmerman, the examiner’s primary reference, discloses in
Figure 1 a container comprising an innermost container 10 formed
of a material having good heat transfer properties, an outermost
container 14 formed of a material having good heat insulation
properties, and thermodynamic material 18 disposed between
containers 10 and 14 and selected to have a phase change
temperature within the range of the desired temperature for use
of a heated material to be disposed in and dispensed from the
container. Zimmerman envisions that the container may be used,
for example, as a coffee cup. As explained at column 1, line 70,
through column 2, line 9:
It is of course well known that coffee quite
frequently is served at a temperature at which it is
too hot for immediate drinking. In fact the coffee may
be so hot as to require a number of minutes for it to
cool to the desired drinking temperature range of
approximately 145-155° F. The container of Figure 1 is
adapted to cool the coffee down from even the boiling
temperature to said desired range in less than one
minute’s time and to thereafter maintain the
temperature within the desired range, for a period of
many minutes. For this purpose, the preferred material
18 is bee’s wax, having a melting point of
approximately 147° F.
As conceded by the examiner (see page 3 of the answer),
Zimmerman does not respond to the limitation of independent
