Abstract

An elongated sheet (10) is used to form a thermally insulated cup (30). The sheet includes a pair of spaced apart smooth portions (12, 13) connected by a middle portion (11). The smooth portions are folded on opposite sides of the middle portion. The middle portion is corrugated, otherwise distorted, or deformed to create an insulating air space. Ends of the smooth portions are joined together and a bottom closure (14) is attached. The finished cup includes a smooth outer shell (12S), a smooth inner shell (13S), and a middle layer (11L) sandwiched therebetween. In an alternative embodiment (Fig 5A), the bank may have the insulating portion (34) at one end instead of the middle, and it is suitably folded so that the insulating layer comes out as a middle layer (Fig 6A). In another embodiment, the blank has just two sections (Fig 7A) and is formed so that the cup has an outer corrugated layer (34) and an inner smooth layer (32).
