Abstract: A cup sleeve includes two opposing side walls, two opposing support brackets, and two opposing handles. The two opposing side walls are formed by folding a sheet of cardboard in half and joining two lateral edges of the sheet of cardboard, so that a beverage container can be placed between the side walls. The two opposing support brackets are respectively formed at the side walls. The two support brackets can be folded upwardly about their bottoms to extend above the top edges of the side walls. The two opposing handles are respectively formed at the two support brackets. The two handles can be folded outwardly about their bottoms to facilitate a user in taking the cup sleeve together with the beverage container. Moreover, the cup sleeve can provide the function of thermal insulation and heat preservation.
