Abstract

In the shaping of a packing container from a tubular blank of paper, involving the use of a tube having a joint of the overlapping type along the longitudinal edge of the web, an improved rigidity of the container is achieved by closing the longitudinal joint of the finished package to take up at least one-fourth of one side wall of the package.
