ABSTRACT:
A collapsible drum-type container is formed by scoring lines on a generally rectangular blank of fiberboard or the like so that the blank can be initially folded along one score line into two flat overlying panels. The longitudinal free edges of the panels are sealed together to form a flattened tube. The flattened tube is then opened and refolded along other score lines to provide a flat envelope having an upper open end and a closed lower end defined by an inwardly folded gusset panel between the two side walls of the refolded flattened tube.
