Thermos Flasks - Versatile Promotional Gifts

The thermos flask is a glass vessel with double walls. The inner and outer walls are both sealed to prevent the loss of heat through conduction and radiation. The inside of the vessel is also coated with silvered glass, which reduces heat loss from radiation. A stopper is used to seal the mouth of the vessel. When not in use, the thermos flask is placed over a cork pad to prevent heat from escaping. Unlike aluminum, they are immune to chemicals and can last up to six hours without losing their heat. The flasks are available in various shapes and sizes and can be personalized with your logo or design. These versatile promotional gifts are practical and can make a great gift for any occasion.

Best Flasks And Thermal Cups To Buy

• Vacuum Flask Bottle with Stainless Steel KTZ0555 

The vacuum flask was devised to preserve liquefied gases by preventing the transfer of heat from the surroundings to the liquid. The evacuated space between the walls is practically a nonconductor of heat; radiation is reduced to a minimum by silvering the glass or steel. The chief path by which heat can be communicated to the interior of the inner vessel is at the vessel’s neck, the only junction of the walls, which therefore is made as small as possible. This thermal isolation applies equally to heat, a hot liquid remaining at a high temperature in the flask for several hours.

Also, many larger bottles have "swivel" nozzles so you can pour from the bottle without completely removing the cap. An all-in-one cup is also useful.
