Abstract
A dual wall container formed of a laminated blank wrapped about the longitudinal axis of the container to define a inner sidewall and an outer sidewall. The laminated blank comprises an inner sheet affixed to an outer sheet, wherein expansion joints may be provided on the outer sheet to enable the same to increase in circumference as the container is formed. Preferably, scores are provided within the inner sheet so as to form annular air pockets extending circumferentially around the container between the inner and outer sidewalls for uniform insulation.
