How long will my food stay hot or cold in the ThermoFlask jar?

The jar uses Temp-Lock vacuum insulation to slow temperature exchange so hot foods stay warm and cold foods remain chilled for extended periods. Typical performance holds heat for up to 12 hours and cold for up to 24 hours under normal conditions.

• Hot retention: designed for up to 12 hours of warmth.
• Cold retention: designed for up to 24 hours of chill.
• Best results when pre-warmed or pre-cooled before packing.

Is the lid truly leakproof and suitable for soups or sauces?
