PROBLEM TO BE SOLVED: To simplify manufacture of a double container which has clear print to be visually attractive, prevents from stacking and is excellent in heat insulation effects. SOLUTION: A barrel cover 2 made of a paper board with a printed indication applied on an external surface is wound around the exterior of a barrel 5 of a container body 1 molded of a foamed resin into a cup form. Thereafter, the barrel cover 2 is moved in an axial direction of the container body 1 on the external surface of the barrel 5 until an upper end 2a of the cover 2 comes into contact with a lower surface 6a of a flange 6 and glued to the external surface of the barrel 5. If a plurality of the double containers are vertically stacked, they are easily removed from an internal surface of the body 1 of the lower double container since the barrel cover 2 of the upper double container has an easy-to-slip external surface where the print 8 is applied, thereby preventing the double containers from being stacked. The desired print 8 can be clearly applied on the external surface of the barrel cover 2 made of the paper board, thereby supplementing printing properties in which the container body 1 lacks. Since the container body 1 is excellent in heat insulating properties, it can supplement heat insulating effects in which the barrel cover 2 lacks. |
