Doshisha (Chuo-ku, Osaka) will release "Drinking Super Cold Tumbler", which lowers the temperature of the drink the moment you put it in, at mass retailers nationwide in early March. The price is open.
The moment you pour beer, it's ready to drink !?
"Cold tumbler for drinking" is a tumbler that lowers the temperature the moment you pour a drink such as beer. The main body and inner bottle are separated, and water is poured between them and frozen in the freezer for at least 12 hours before use.
The double effect of the main body and inner bottle cools it down to "gekiteki"!
It is said that the temperature of the drink can be "rapidly dropped" by the vacuum insulation of the main body, which has a double stainless steel structure, and the ice layer that freezes the water between the main body and the inner bottle. For example, if you pour 350 ml of canned beer at 4 degrees, it will drop to 1.4 degrees in 1 minute and 1.0 degrees in 5 minutes (reference value measured at room temperature around 25 degrees).
The approximate size of the product is 86 mm in diameter x 142 mm in height. The capacity is about 420 ml.
I want to drink a crisp cold beer in the hot summer
