The original vacuum flask was invented by Sir James Dewar, a scientist at Oxford University in 1892.  These early flasks, sometimes called Dewar flasks, were made of glass, with an outer and inner container separated by a vacuum which ensured the reduction of heat transfer by convection or conduction.  In 1903 German glass engineer Reinhold Burger, who had studied the effect of double-walled glass containers for years improved the design  to make sure the layer of silver used to reflect the heat radiation would not flake off.  To protect the glass he covered the flask in a lightweight metal casing and also added the screw-on cup.  The first vacuum flasks for commercial use came in 1904 with Burger's own slogan "Keeps it cold, keeps it hot - without fire and ice". In 1909 Burger sold the patent to the company Charlottenburger Thermos AG and in 1920 the thermos flask went into series production, becoming a worldwide best seller.

Wide Mouth Thermos come in a range of materials - glass with a polyurethane jacket is less expensive but vulnerable to damage. Stainless steel is unbreakable but comes at a higher cost.  All should have double-wall vacuum insulation.  The styles available range from individual mug size to tubs and jugs for use in the home.  The suppliers above should give you great choice, many at bargain prices.
