Domestic Use
Vacuum flasks are used to maintain their contents (often but not always liquid) at a temperature higher or lower than ambient temperature, at ambient pressure of approximately 1 atmosphere (14.7 psi). Domestically and in the food industry, they are often used to keep food and drink either cold or hot. A typical domestic vacuum flask will keep liquid cool for about 24 hours, and warm for up to 8.
Some vacuum flasks include one or two fitted cups for ease of use with beverages, especially during travel or picnics.

Famous quotes containing the word domestic:
“To meet the objections of some inveterate cavillers, I may as well state, that if I dined out occasionally, as I always had done, and I trust shall have opportunities to do again, it was frequently to the detriment of my domestic arrangements.”
—Henry David Thoreau (1817–1862)
“Our domestic problems are for the most part economic. We have our enormous debt to pay, and we are paying it. We have the high cost of government to diminish, and we are diminishing it. We have a heavy burden of taxation to reduce, and we are reducing it. But while remarkable progress has been made in these directions, the work is yet far from accomplished.”
—Calvin Coolidge (1872–1933)
