The California company The Joseph Company has created cans for self-cooling beverages. Under the name of Chill-Can, they have begun to sold coffee as a pilot experience in fifteen establishments of the 7-Eleven chain located in Los Angeles.
The mechanism works through a piece located at the base of the can that has to be rotated. This releases CO2 from an internal reservoir that reduces the temperature of the beverage 16 degrees Celsius in a maximum of 90 seconds. The system increases the weight of the container by 150 grams and doubles the price of the product.
The first drink to rely on this innovation has been Fizzics Sparkling Cold Brew Coffee, a new line of frozen coffee. “Because self-cooling technology is very innovative, we wanted to introduce it with an innovative drink,” said Tim Cogil, marketing director of 7-Eleven.
