Coffee sleeves allow coffee houses, fast food restaurants, and other vendors to avoid double-cupping, the practice of using two (or more) nested paper cups for a single hot beverage.
The coffee sleeve was invented in 1991 by Jay Sorensen[1] and patented in 1995[2] (under the trademarked name Java Jacket), and are now commonly utilized by coffee houses and other vendors that sell hot beverages dispensed in disposable paper cups.
[citation needed] The sleeve was invented while Sorensen was driving his daughter Ryeder to school and spilt a cup of coffee in his lap.
The Java Jacket first appeared at the Seattle Coffeefest in 1995 and Sorensen and his wife Colleen were overwhelmed with requests and orders to fill.
Coffee sleeves should not be confused with fixed cup holders.
