Abstract
A one piece beverage insulator in the form of a beverage container holder with an open top that is die cut from a sheet of insulative foam either open cell or closed cell laminated with a surface vinyl film. The one piece beverage insulator die cut pattern is in the form of two mirror image side halves joined by a center bottom shaped to conform to the bottom of a beverage container to be held by the finished holder. The die cut holder pattern is folded over on itself with the side halves aligned but with the inside foam sides of the halves facing out and the side edges are stitched or vinyl welded together after which the holder is pulled inside out through its open top returning the vinyl surface to the outside. This finished holder is stored in a collapsed flat state to be opened when receiving a beverage can or other beverage container to be held and insulated by the holder.
