  The right front lower gusset 353 and the right rear lower gusset 352 have the same height. Therefore, the height dimension of the right front gusset 351 is larger than the height dimension of the right rear gusset 352.

  When looking at the state where the upper lid part 32 and the lower lid part 33 are opened, the upper lid part 32 is taller than the lower lid part 33. The upper lid 32 and the right front gusset 351 have the same height, and the lower lid 33 and the right rear gusset 352 have the same height.

  In the right front upper gusset 354, a right front gusset skin material 355, a right front upper stiffening member 359, and a right front gusset back material 356 are stacked in this order. On the other hand, in the lower right front gusset 353, the reinforcing member is omitted, and the right front gusset skin material 355 and the right front gusset back side material 356 are stacked in this order. The reinforcing member is also omitted from the right rear gusset 352, and the right rear gusset skin material 357 and the right rear gusset back side material 358 are stacked in this order.

  In the assembled state, the right front lower gusset 353 and the right rear gusset 352 are connected. In addition, the right front lower gusset 353 and the right rear gusset 352 are formed diagonally with a right front bending portion 453 and a right rear bending portion 454 functioning as bendable portions.

  Further, the angle at which the upper lid portion 32 and the right front gusset portion 351 are connected at the right front connection portion 443 is fixed by the reinforcing member and the upper flat metal bar 371. On the other hand, the angle at which the lower lid portion 33 and the right rear gusset 352 are connected at the right rear connection portion 444 is not fixed and can be freely changed.

  Therefore, when the upper lid part 32 is opened, both the left gusset part 34 and the right gusset part 35 are extended in a flat plate shape, and as shown in FIG. 3, the lower lid part 33 is also opened substantially simultaneously. .

  Further, when the upper lid part 32 is closed, the left gusset part 34 is folded in a posture in which the left front bending part 451 and the left rear bending part 452 are folded and folded outward in a triangular shape. The bending portion 453 and the right rear bending portion 454 are folded and folded in a triangular shape so as to fall outward, and the bending angles of the left front connecting portion 441 and the right front connecting portion 443 are always maintained as described above. However, the left rear connecting portion 442 and the right rear connecting portion 444 also bend to the same extent as the left front connecting portion 441 and the right front connecting portion 443, whereby the lower lid portion 33 is also closed ( (See FIG. 1).

  That is, the lower lid 33 is opened and closed in conjunction with the opening and closing of the upper lid 32 through the bending and stretching of the left gusset 34 and the right gusset 35.

  Therefore, when the user only applies the opening / closing action to the upper lid part 32, not only the upper lid part 32 opens and closes, but also the lower lid part 33 opens and closes in conjunction with this. In order to allow the user to open and close the upper lid 32, the upper lid 32 may be opened and closed, or the strap protrusion 362 may be gripped and pulled in the opening and closing direction.

  Note that, even when the lower lid 33 is closed from the state where the upper lid 32 and the lower lid 33 are open (see FIG. 3), the upper lid 32 is not interlocked and remains open (see FIG. 2).

  According to the invention of this embodiment, both the one lid and the other lid are opened and closed simply by performing an operation for opening and closing one lid. Therefore, the effect that the user can easily open and close the lid is achieved.

  In addition, a writing instrument such as a pencil and a pen, a ruler, an eraser, and the like can be stored. Therefore, the effect that it can be used as a writing instrument case is produced.

  Further, it is possible to prevent the writing implement from jumping out from both ends of the writing implement case. Therefore, there is an effect that the writing implement can be prevented from being lost or broken by dropping.

  Further, it is possible to prevent the lid from being opened by an external force such as an impact. Therefore, even when an external force such as an impact is applied, the writing implement can be prevented from being lost or broken by being dropped.

  Furthermore, the lid can be opened and closed only by the user grasping the opening and closing member and pulling the lid in the opening and closing direction. Therefore, the effect that the user can easily open and close the lid is achieved.

  Further, the internal space of the writing instrument storage section is not pressed. Therefore, there is an effect that the writing implement in the writing implement storage unit can be prevented from being damaged inside the writing implement storage unit.

  The present invention may be embodied in various other forms without departing from its spirit or main characteristics. Therefore, the above-described embodiments are merely examples, and should not be construed as limiting. The scope of the present invention is indicated by the claims of the utility model registration, and is not bound by the specification text at all. Further, all modifications and changes belonging to the equivalent scope of the claims for utility model registration are within the scope of the present invention.

  The present invention can be used for a writing instrument case. The present invention can also be used in other cases such as a tool box.
