Coffee cup sleeve

Coffee cup sleeve is a device that is designed to fit around a coffee cup to provide insulation and protection for the hand while holding a hot beverage. The coffee cup sleeve, also known as a coffee cup jacket, coffee clutch, or coffee cozy, is typically made from paper or cardboard and is often used with disposable coffee cups.

History

The coffee cup sleeve was invented in 1991 by Jay Sorensen after he accidentally spilled a cup of hot coffee in his lap while driving. His invention, which he named the "Java Jacket," was patented in 1995. The invention of the coffee cup sleeve has significantly reduced the need for "double cupping," or using two cups for a single serving of coffee to prevent burns.

Design and Function

The primary function of a coffee cup sleeve is to provide a layer of insulation between the hot beverage and the person's hand. This not only protects the hand from burns, but also helps to keep the beverage hot for a longer period of time. The sleeve is typically designed to fit snugly around the cup, and often features a corrugated design to provide additional insulation and grip.

Environmental Impact

While coffee cup sleeves are typically made from paper or cardboard, their production and disposal still contribute to environmental waste. Many coffee shops and companies are now offering reusable coffee cup sleeves as an eco-friendly alternative. These reusable sleeves are often made from fabric or silicone and can be used with a variety of cup sizes.
