  Embodiments will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a document carrying case according to an embodiment.

  As shown in FIG. 1, a document carrying case 1 has a main body 2 formed by bending an elastic resin sheet or the like, and a lid 3 extending therefrom, and the main body 2 has a pair of handles. 4, 5 are attached.

  The main body 2 has a thin box shape, and has a front surface 21 provided with a protrusion 6 a, a back surface 22, and an opening 26. Through this opening 26, documents and the like can be taken in and out.

  The lid 3 extends flexibly from the back surface 22 of the main body 2, and overlaps the front surface 21 while covering the opening 26 at the top of the main body 2. The free end 31 at the tip of the lid 3 is provided with a hole 6b formed by a notch. The hole 6b forms the fastener 6 together with the protruding portion 6a by fitting into the protruding portion 6a of the front surface 21 with the lid portion 3 closed.

  The handles 4 and 5 attached to the front surface 21 and the back surface 22 of the main body 2 are formed of a flexible material such as rubber, and are disposed at symmetrical positions on the front surface 21 and the back surface 22 of the main body 2.

  FIG. 2 is a partially enlarged view of the fixing member of the handle.

  As shown in FIG. 2, fixing members 41 and 51 including convex portions 41a and 51a and concave portions 41b and 51b are formed at the corresponding positions at the tips of the grips 4 and 5, respectively. The tips of the hands 4 and 5 are fixed to each other. In the illustrated example, the convex portion and the concave portion are fixed members, but a magnet or the like may be used.

  FIG. 3 is a development view of the main body 2 and the lid 3 of the document carrying case 1 according to the embodiment.

  As shown in FIG. 3, the main body 2 made of one resin sheet is bent at a predetermined position indicated by a one-dot chain line, and the overlapped sheets are welded to form a box shape. U-shaped notches 26a are provided at the upper end portions of the front surface 21 and the rear surface 22 so as to enlarge the opening 26, thereby making it easy to put in and out stored items such as documents. In addition, holes are formed in the attachment portions 4 a and 5 a of the handles 4 and 5 in the front surface 21 and the rear surface 22. The handles 4 and 5 are fixed to the holes by a method such as screwing.

  Although not particularly limited, the lid 3 is welded onto the back surface 22 of the main body 2 as a resin sheet different from the main body 2. And it bend | folds in the bending part 3a along the dashed-two dotted line in a figure.

  As shown in the enlarged sectional view in the dotted circle in FIG. 3, a bent groove is formed in the bent portion 3a of the resin sheet to facilitate the bending of the hard resin sheet.

  As a material for the resin sheet, for example, light, hard, excellent waterproof and inexpensive polypropylene can be used.

  In addition, the notch 26a of the main body 2 is provided as necessary, and may not be particularly required.

  FIG. 4 is a side view showing a state where the handles 4 and 5 of the document carrying case 1 are released.

  As shown in FIG. 4, the lid 3 welded to the back surface 22 of the main body 2 is bent and has a U-shape when viewed from the side.

  The lid portion 3 formed by bending a resin sheet that is an elastic body tries to return to a flat shape by generating a restoring force in the bent portion 3a. The fastener 6 is for fixing the notch 6b with the hole 6b by the notch 6a, and there is a possibility that the free end 31 of the lid portion 3 jumps up in the direction away from the main body 2 with the fastener 6 alone.

  Thus, the following structure of the present embodiment prevents the lid 3 from jumping up even with a fastener 6 having a simple structure.

  FIG. 5 is a side view showing a state in which the lid 3 and the handles 4 and 5 of the document carrying case 1 are closed.

  As shown in FIG. 5, in the document carrying case 1, the position F of the free end 31 of the lid portion 3 is formed in the vicinity of the attachment portion 4 a of the handle 4. As a result, the free end 31 of the lid 3 is pressed against and held by the main body 2 side by the attachment portion 4a of the handle 4, and the lid 3 is unlikely to jump up.

  Moreover, the force which presses the cover part 3 against the main body 2 side acts against the restoring force of the cover part 3 by closing the upper parts of the handles 4 and 5 with the fixing members 41 and 51. Thereby, the splashing of the cover part 3 can be prevented.

  Further, in the present embodiment, the lid 3 is fastened with a simple fastener 6 including a hole 6a and a protrusion 6b. According to this structure, the lid 3 can be easily fastened to the fastener 6 even when the main body 2 is bent.

  In addition to the above, since the handles 4 and 5 are attached to the main body 2, the load when the handles 4 and 5 are held does not act on the lid 3, and the lid 3 is the clip 6. The state where it was fastened can be maintained, and it becomes difficult to cause a trouble that the lid portion 3 opens unexpectedly during use. Further, the fastener 6 can be carried without being fastened.

  In conventional document carrying cases, it is necessary to provide a fastener near the bottom surface that is not easily affected by bending, and in accordance with this, it is common to extend the length of the lid portion to the bottom surface side, and the lid portion is long. It was. For this reason, it has been difficult to open and close the long lid in the conventional document carrying case.

  On the other hand, according to the present invention, the clip 6 can be provided on the upper part of the front surface, the length of the lid 3 can be further shortened, and the document 3 can be easily opened and closed. Case 1 is obtained.

(Other embodiments)
FIG. 6 is a perspective view showing a modification of the document carrying case.

  The document carrying case 10 according to the illustrated modification differs from the document carrying case 1 in that a tongue piece 22 a is provided on the back surface 22 side of the main body 2. Since the other configuration is the same as that of the document carrying case 1, detailed description thereof is omitted.

  The tongue piece 22 a is made of a resin sheet that protrudes upward from the vicinity of the center of the upper end of the back surface 22, and is formed inside the lid portion 3.

  As shown in the figure, when the lid portion 3 is bent and the tip portion is inserted between the lid portion 3 and the tongue piece 22a, the lid portion 3 is caught by the tongue piece 22a and can be kept open.

  Thereby, in the portable case 10 for documents which concerns on this modification, the take-out of the inside of the main body 2 can be taken out easily.
