to keep the contents warmer or colder than the surrounding
environment. As shown in Figure 1, the insulated container 1
includes an inner vessel 2 (e.g., a high-density polyethylene
container) provided with a neck aperture 3. The inner vessel
2 is surrounded by an expanded polystyrene jacket 4 which
comprises an upper half 4a and a lower half 4b. Davis teaches
that an
appropriate cavity 5 is formed in the lower half 4b such that
the inner vessel 2 may be snugly accommodated therein with the
vertical axis of the inner vessel 2 inclined away from the
vertical towards the middle of one of the top edges of the
inner vessel 2 by about 20°. The insulated container 1 also
includes a
dispensing tube 11 and a manually-operated pump 12 which may
be used to dispense the contents of the inner vessel 2. The
pump 12 is adapted to engage the neck aperture 3 of the inner
vessel and the dispensing tube then extends down into the
inner vessel 2 to a location adjacent the bottom thereof.
Davis further teaches (column 3, lines 1-8) that when the
container 1 and its contents are being stored and one does not
wish to dispense the contents, the pump 12 and dispensing tube
