THERMOS KK (Tokyo; Shoji Toida President), a world leader in vacuum flask products that offer people and society a lifestyle that is both comfortable and environmentally friendly, will release the newly designed Thermos Vacuum Insulated Tumbler series on Tuesday, March 1, 2016. The Vacuum Insulated Tumblers feature a stainless steel vacuum insulated construction that keeps your drink the perfect temperature until you drink it and does not create condensation even when filled with ice.

No condensation even when filled with ice! Also perfect for beer!
Thermos Vacuum Insulated Tumbler (JDE-340/420/600)

Our Vacuum Insulated Tumblers use the same vacuum insulated construction as our vacuum flask products to keep cold drinks cold and hot drinks hot, retaining the perfect drinking temperature for hours. With its casual cup feel for everyday use, the tumbler series has enjoyed popularity since it was released. The outside of the tumbler does not get hot even when there is a hot beverage inside, while condensation does not form even when filled with a cold beverage.

Our Vacuum Insulated Tumblers are especially popular with men and are ideal for enjoying a cold beer, iced coffee, or other cold beverage. We have now redesigned the tumbler series with increased capacity to better enjoy cold drinks from cans or plastic bottles with added ice as well as beer poured to enjoy a foamy head. The new tumblers come in three capacities: The 340-ml type is perfect for adding ice to small cans of coffee or other small beverages either cold or hot, the 420-ml type is perfect for pouring a 350-ml can of beer, and the large 600-ml size is ideal for pouring a 500-ml can of beer or drink from a 500-ml plastic bottle.

The stainless steel vacuum insulated construction not only keeps the beverage inside at the best hot or cold temperature for drinking, it also prevents the hot or cold temperature from transferring to the tumbler’s exterior when holding it and does not form condensation even when filled with ice. It offers much higher cold-temperature retention than ordinary glass cups. In our own product testing, Vacuum Insulated Tumblers kept ice frozen for six hours. (Testing conditions of 20°C ± 2° room temperature with 4°C water + ice. Test by Thermos. See p. 2 of this press release for details.)
