The Thermos Nissan Flask is designed for travelling. Once you have unscrewed the lid at the top of the thermos, you remove a second plastic cup and you then need to push a button which then opens a third leak-proof lid, which has a small opening from which you can pour your coffee. This is an ideal vacuum bottle for work, as you can carry coffee made exactly as you like. It works well for short tourist trips where you are on the go all day and don't want to buy expensive coffee.
It has a stronger 18/8 stainless steel interior and exterior than the stainless king thermos (which is reviewed below). It also has a retractable handle and a detachable shoulder strap to make it easy to pour and easy to carry. It keeps liquids hot for about 7 hours. It comes in various sizes, see below:
