<p>PURPOSE: To reduce weight and enable formation from one-piece blank with the first and second panels by forming an inner sleeve with the first panel; an outer sleeve, cover and each end flap with the second panel, and a hinged top with a rounded end. CONSTITUTION: An inner sleeve 12 is formed with the first panel defined by an edge 103 and a line 112 of a board paper blank 100, while an outer sleeve 11 housing the inner sleeve 12, a cover member 13 and end flap 14-17 are formed with the second panel defined from the line 112 to the other edge 104 of the blank 100. The inner sleeve 12 is set at a height lower than that of the outer sleeve combined with a cover member 13. And a cut line 105 is formed at position of the line 112, short notched lines 107 are up to a line 113 of the back panel portion 18, short notched lines 108 are from the edge 104 to the line 114, and a cut line 106 connects the both notched lines 107, 108. This blank 100 is folded to form a box structure 10.</p> |
