Each reinforcement flap 30 comprises a base piece 37, a retaining piece 38 which is provided with an engagement insert 381.
The front, rear, left and right side flaps 2, 3, 4, 5 are provided with an extended top fold 21, 31, 41, 51 and an extended inner fixing fold 22, 32, 42, 52 respectively. An elongated slot 24, 34 is disposed at each end of the extended top fold 21, 31 respectively; and some of the elongated slots 24, 34 extend into the inner fixing folds 22, 32. The left and right inner fixing folds 42, 52 are provided with an insertion tongue 44, 54 at each end thereof respectively.
The front and rear inner fixing folds 22, 32 are divided into five engagement inserts 23, 33 by recessed cuts 8 respectively. The left and right inner fixing folds 42, 52 are provided with a pair of retaining cuts 43, 53. On the edge of the retaining piece 38 of the reinforcement flap 30 is also provided with a retaining cut 36 which corresponds to each retaining cut 43, 53 respectively.
The modified dust cover 6, as shown in FIG. 2A, is provided with a pair of round protrusions 61 on the right and left sides thereof respectively; and a pair of elongated grooves 62 disposed on the front and rear edges thereof. The dust cover 6 is disposed on top of a computer keyboard 7 first in assembly.
To fold the one piece board 1 into a topless case, the front and rear side flaps 2, 3 are folded upward along the dotted folding lines 25, 35 so as to make the same perpendicular to the box base 11; afterwards, the top folds 21, 31 and the inner fixing folds 22, 32 are folded along the folding lines 25, 35 with each fixing fold 22, 32 perpendicular to each top fold 21, 31 respectively; and the top folds 21, 31 perpendicular to the front and rear side flaps 2, 3 whereby the front and rear side flaps and the top folds and the inner fixing folds are folded into rectangular loop shape respectively.
Next, the corner flaps 20 disposed at each end of the front and rear side flaps 2, 3 respectively are folded inward toward the side flaps in a perpendicular manner. Each reinforcement flap 30 are folded with the base piece 37 and the retaining piece 38 perpendicular to each other. To hold the reinforcement flap 30 in place with the top folds 21, 31, the engagement inserts 381 are engaged with the elongated slots 24, 34.
To fold the one-piece board 1 into a topless case, the left and right side flaps 4, 5 are folded along the folding lines 45, 55 in perpendicular to the box base 11 and the top folds 41, 51 are folded along the folding lines 45, 55, and the left and right inner fixing folds 42, 52 are also folded in perpendicular to the top folds 41, 51 respectively.
