Description

  The present invention relates to a case, and more particularly to a structure of a corner portion of a case that can be used as, for example, a card case.

  FIG. 28 is a perspective view showing an example of a conventional card case. The card case 1 opens and closes a bottom surface 2, two side surfaces 3 facing each other on both sides of the bottom surface 2, two end surfaces 4 facing each other so as to block both sides of the two side surfaces 3, and an opening opposite to the bottom surface 2. And a lid member 5 for

  In order to produce such a card case 1, a plate material having a development view as shown in FIG. 29 is prepared. In the plate shown in FIG. 29, the dotted line indicates a crease. In this development view, a surface to be a side surface 3 is formed on both sides of a surface to be a bottom surface 2 of the card case 1 through a fold. Furthermore, a surface to be the end surface 4 is formed on the surface to be the side surface 3 through a fold. In addition, a flap surface 6 is formed on the surface that becomes the bottom surface 2 through the fold line so as to overlap the end surface 4 in the same direction as the surface that becomes the end surface 4. In addition, a surface to be the lid member 5 is formed on one of the surfaces to be the side surfaces 3 so as to face the surface to be the bottom surface 2 through a fold.

  Using such a plate material, the surface serving as the side surface 3 around the surface serving as the bottom surface 2 and the flap surface 6 are bent in the same direction. Next, the surface to be the end surface 4 is bent so as to overlap the folded flap surface 6. Therefore, the flap surface 6 and the two end surfaces 4 are overlapped on one end side of the surface to be the bottom surface 2, and the same configuration is formed on the other end side of the surface to be the bottom surface 2. In such a state, the card case 1 is manufactured by bonding the surfaces to be the two end surfaces 4 that overlap each other. In such a card case 1, since the flap surface 6 is formed, no gap is formed between the bottom surface 2 and the end surface 4 (see Patent Document 1).

  Here, the bending of the portion of FIG. 7 which is an enlarged view of the portion A shown in FIG. 6 is particularly important. In this case, first, as shown in FIG. 8, the first fold 24 is valley-folded, and the second surface 26 is bent toward one surface side of the first surface 22 and raised. Therefore, the second surface 26, the third surface 30, and the fourth surface 40 are disposed so as to be substantially orthogonal to the first surface 22.

  Next, as shown in FIG. 9, the third fold 38 is folded and the fourth surface 40 is bent toward the inner side of the third surface 30. At this time, the third fold 38 is formed so as to be shifted toward the third surface 30 side by the thickness of the plate member 20 with respect to the first fold 24, and therefore the fourth surface 40 is the base surface 22. The outer surface of the bent fourth surface 40 and the first fold line 24 are arranged in a straight line.

Further, the fifth fold line 48 is shifted toward the sixth surface 50 side by the thickness of the plate member 20 with respect to the second fold line 28, that is, shifted to the outer surface side of the raised third surface 30. Since it is formed, the outer surface of the folded third surface 30 and the fifth fold line 48 are arranged on a straight line.
Here, since the rectangular hole 36 is formed across the second surface 26 and the third surface 30 with the second fold 28 interposed therebetween, the second hole 26 is formed on the side opposite to the fourth surface 40. A through hole 54 that is continuous with the second surface 26 and the third surface 30 that is bent at the fold line 28 is formed.

In addition, a first notch 42 is formed over both the first surface 22 and the second surface 26 at the end of the first fold line 24 on the third surface 30 and fourth surface 40 side. Yes. For this purpose, the first notch 42 is disposed at a corner where the first surface 22 and the fourth surface 40 overlap, the second surface 26 and the third surface 30 are gathered.
Therefore, the corner portion where the first notch portion 42 is arranged is not a pointed state but has a rounded shape. At this time, since the end of the fourth surface 40 is in contact with the second surface 26, the fourth surface 40 exists inside the first notch 42, and the first notch A through hole leading to the inside of the box 12 is not formed in the portion where 42 is disposed.
