The fourth easy break line 26a is U-shaped. The fourth easy break line 26a has a pair of first portions extending perpendicularly to the fourth fold easy line 26b, and a second portion connecting the first portions and extending in parallel with the fourth fold easy line 26b. .

  The second rear lid flap 8 has a rectangular main body 27a and a pair of insertion pieces 27b extending from the front end edge of the main body 27a. The main body 27a has a rectangular shape. The main body 27 a extends from substantially the entire region of the rear edge of the second side plate 4. The pair of insertion pieces 27b have a widened portion whose width gradually increases from the proximal end side toward the distal end side and a reduced width portion whose width gradually decreases in this order. The width of the leading edge of the insertion piece 27b is equal to or less than the length of the fourth fold easy line 26b. The width of the base end edge of the insertion piece 27b is equal to or less than the length of the fourth fold easy line 26b, and is preferably substantially the same as the length of the fourth fold easy line 26b. On the other hand, the maximum width of the widened portion of the insertion piece 27b is larger than the length of the fourth easy-to-bend line 26b. The difference between the maximum width and the length of the fourth fold easy line 26b can be about three times or less of the sheet thickness, and if the sheet thickness is 5 mm, preferably more than 0 mm and 15 mm or less, 5 mm or more and 10 mm or less are more preferable. If the difference is less than the lower limit, the insertion piece 27b may unintentionally come out of the insertion hole 26. Conversely, if the difference exceeds the upper limit, it may be difficult to insert the insertion piece 27b into the insertion hole 26.

Next, in this overlapping state, the second rear lid flap 8 is pushed inward. By this pushing, the first rear lid flap 7 swings inward with the boundary line with the first side plate 3 as the rotation axis, and the leading edge of the insertion piece 27b formed in the second rear lid flap 8 is the first rear lid. It moves to the position of the insertion hole 26 in a state of being in contact with the flap 7. At this time, since the force to return to the outside by the reaction force of the sheet material acts on the first rear lid flap 7, the second rear lid flap 8 is moved in a direction to weaken the pressure on the first rear lid flap 7. The insertion piece 27b is easily inserted into the insertion hole 26. Thus, the box sheet 1 has the first rear lid flap 7 and the first rear lid flap 7 because the first rear lid flap 7 has the insertion hole 26 and the second rear lid flap 8 has the insertion piece 27b. 2 The rear lid flap 8 can be easily and reliably engaged.
