It is configured to include second folded pieces 115 and 116 connected to both ends 111 and 112 in the direction.

[0004] Slits 120 are formed along both ends of the first folded pieces 108 and 109 in the longitudinal direction, respectively.
Round holes 121 are formed adjacent to each other. Further, three slits 124 are formed in the central portion of the first folded pieces 108 and 109, respectively, and between the slits 124 and the upper and lower edges 105 and 106,
Each of the trapezoidal holes 126 is formed.

[0005] At both ends in the longitudinal direction of the second folded pieces 115 and 116, a claw piece 128 is formed through a notch 127.
Are formed at the respective corners. Also, on the back side in FIG. 7 of the second folded pieces 115 and 116, a locking member 130 in which a hook cloth and a pile cloth are paired, respectively.
Are fixed in two places. In FIG. 7, reference numeral 131
Indicates a folding line formed in each area of the first folded pieces 108 and 109 and the second folded pieces 115 and 116 to secure a certain amount of storage in the drawings and the like.
Reference numeral 32 denotes a folding line for folding the file 100 in half.

In the above configuration, the file 100 is
Normally, the second folded pieces 115 and 116 are
The first folding pieces 108 and 109 are folded inward so as to be parallel to the plane 102, respectively, and the first folding pieces 108 and 109 are folded thereon to form a space for storing a certain amount of drawings therein. When the file 100 is folded along two folding lines 132 provided at the center of the cover main body 103, the locking member 130 is turned into the first folded pieces 108, 1
09 are engaged with each other through the round holes 121, whereby the folded state is continuously maintained. Here, when storing a drawing or the like in the file 100, the file 10 is unlocked by the locking member 130.
Open 0. Then, as shown in FIG. 8, when the second folded-back pieces 115, 116 are opened in the direction in which they are raised with respect to the surfaces of the cover sheets 101, 102, the second folded-back pieces 115,
Claws 128 formed on both longitudinal edges of the slit 116 are formed on the slits 1 formed on the first folded pieces 108 and 109.
The first and second folded pieces 108, 109 and 115, 116 stand upright to temporarily form a box in which the upper surface of the cover body 103 is completely open. Thus, the drawings and the like can be stored on the cover main body 103.

[0007]

However, in such a file 100, the second folding piece 11 is used.
The first and second folded pieces 108 and 109 are raised even if the first and second folded pieces are opened to the position where the above-mentioned engagement is performed.
, 115 and 116 are all standing up to the position inclined inward, and the plane area of the cover body 103 is reduced. Therefore, when accommodating a drawing having a relatively large size, especially a drawing having a size close to the plane area of the cover body 103, the free edges of the folded-back pieces collide with each other, which hinders the accommodation. On the other hand, when the stored drawing is taken out, the folded-back piece becomes an obstacle when a finger is inserted below the outer peripheral edge of the drawing.

When the second folded pieces 115 and 116 are strongly opened outward, the slit 120 and the claw 1
28 is disengaged, and the second folded piece 1
15 and 116 must be folded inside the first folded pieces 108 and 109, and there is a disadvantage that a troublesome reassembly is required. In this case, the second folded pieces 115 and 116 and the first folded pieces 108 and 1
It is conceivable to bond the corresponding edges of the file 100 to each other, but this causes a disadvantage that the bonded portion is easily detached by repeatedly repeating the operation of closing and opening the file 100.
