Abstract
A blank structure for liquid having horizontal and vertical fold lines, bordered by specifically designed indented fold lines, the depth of grooves of the fold lines are gradually decreased toward the crossings of the respective fold lines. Thus, cracks or pinholes at the corners of the folded blank due to the folding stress in case of forming a container can be completely prevented.
