Wish your coffee would stay hot longer? Tired of using those cumbersome cup sleeves? The Insulair cup is a multi-layered paperboard cup or container designed with a corrugated middle layer of tiny air pockets. This patented design insulates similar to a thermos. Much like the vacuum between the walls of a thermos, the air pockets in the Insulair cup slow down the rate of heat loss, keeping drinks hot longer and hands cooler. Because heat does not flow out quickly, it does not easily enter the container either. For this reason, iced drinks can also be kept cold for longer periods of time. The Insulair cup eliminates the need for foam cups, as well as the waste and inconvenience of double cups and cup sleeves.
