<p>PURPOSE: To hold and carry the products such as cakes, pastries or the like without breaking a box or squashing the products by the deformation of an edge part by connecting the strengthening strips through a fold line, projecting these two strengthening strips to an internal space of the box, and forming a ridge between two flaps by the two strengthening strips reaching the fold line. CONSTITUTION: A box is formed by a cut-out blank comprising a polygonal base part 1 surrounded by the flaps 2 forming the edge side faces of the box. Each flap 2 is formed from a lower part 3 and a tab 4. The lower parts 201A, 202A and the like are surrounded by the strengthening strips 201E, 201F, 202E, and 202F at each side. These strengthening strips are connected to a base by the fold lines 201G, 201H, 202G, 202H, the adjacent strengthening strips 201F, 202E belonging to two adjacent lower parts 201A, 202A are connected by a fold line 300. The flaps 201, 202 and the like are connected to the base 100 by the fold lines 101, 102 and the like. A ridge at a joint part of the two lower parts 201A, 202A is strengthened by the strengthening strips 201F, 202E having the connection adjacent to the fold lines 201H, 202G and the line 300 in such a manner that they are located inside the package.</p> |
