PROBLEM TO BE SOLVED: To provide a method of shrink-packaging a cup-formed container with which a tubular shrinkable film can be reliably fitted over an assembly of containers including an upper cup-formed container stacked on a lower cup- formed container. SOLUTION: The method comprises a step of fitting the tubular shrinkable film 30 over the lower cup-formed container 10 which has been sealed with contents received; a step of then dropping the upper cup-formed container 20 into the shrinkable film 30 fitted over the container 10 while vertically tilting the container 20 from a hopper 41, in which the upper cup-formed containers 20 which have been sealed with contents received are collected with the upside down, thereby putting the container 20 on the container 10; and a step of shrinking the film 30 by heat. Thus, the lower cup-formed container 10 and the upper cup-formed container 20 are shrink-packaged while they are integrated with each other.
