PURPOSE:To make a pack box supporting-spacer of a required thickness easily and accurately in size, by simply folding a blank. CONSTITUTION:A blank 1 consists of a plurality of rectangular sections S (S1-S3) of the same shape. The sections S each can be easily folded along folding lines f1, f3, f5, and f7 to form mountains and along folding lines f2, f4, and f. to form valleys. Circular holes 2 with their centers on their corresponding folding lines, f1, f3, f5, and f7, are punched, stretching over adjacent sections S and forming a neat line in the longitudinal direction of the blank 1. A semicircular paper-pipe support part is made in the upper end edge of a support spacer, which is formed by folding the blank and superimposing the folded parts, by means of the holes without causing mutual displacement. |
