  Next, the left inner piece 63 and the right inner piece 64 on the left and right sides of the front side plate 62 are folded inward (front side plate 62 side) by the respective creases D and N, and as shown in FIG. The leading edge of the right inner piece 64 is brought into contact with the front plate 62 and the overlapped portion is adhered as it is. The shape of the left inner piece 63 and the right inner piece 64 integrated in this way is such that the center of one side edge of the bottom plate 61 side is notched in a concave shape in FIG. The central part of the other side edge of the 65 side is provided in a substantially H shape that is largely cut out in a concave shape. An equipment storage portion 77 surrounded by the left inner piece 63, the right inner piece 64 and the front plate 62 is formed. In this way, the number of members forming the equipment storage section 77 is reduced as much as possible to prevent the equipment storage section 77 from becoming bulky.

  Further, when the front side plate 62 provided with the equipment storage portion 77 is erected by a crease, the part of the equipment storage portion 77 is stored between the folded plates 78, 79 of the left and right outer plates 66, 67. In this way, the folding plates 78 and 79 are not in contact with the parts storing the equipment in the equipment storage section 77. As a result, the folding plates 78 and 79 and the equipment storage section 77 do not interfere with each other, and even if equipment is stored in the equipment storage section 77, it does not swell greatly inside or outside.

  On the contrary, when the left inner piece 63 and the right inner piece 64 forming the equipment storage portion 77 are formed to be large on the front plate 62, the portion storing the equipment also becomes large, and when the front plate 62 is erected, The left and right folding plates 78 and 79 are in contact with the left inner piece 63 and the right inner piece 64 so as to swell greatly inward and outward, and come into contact with cakes stored in the paper box, and there is a gap as a paper box. Invite a bad state.

  Further, when the cold storage body 25 which is one of the fixtures is stored in the fixture storage portion 77, the side edges of the fixture storage portion 77 are notched as described above, so that the circulation of cold air is promoted. From these notches, it can be seen at a glance what equipment is in the equipment storage section 77.

  Then, after the front plate 62 provided with the equipment storage portion 77 is erected on the front end edge of the bottom plate 61 by a fold line, the folding plate 65 is folded to the bottom plate 61 side by a crease, and the right and left locking portions 65a of the folding plate 65 are provided. Are placed on the folded left side piece 68 and the folded right side piece 69, which are respectively folded on the bottom plate 61 side by creases and c, and are locked and fixed to these locked portions 68a and 69a.

Thereafter, the locking piece 70 erected by folding the folding plate 65 at the folding line is raised to the outside by the folding line, and the opening and closing top plate 71 is folded horizontally to the bottom plate 1 side by the folding line to open the opening of the paper box C. The peripheral wall of the opening / closing top plate 71 is put on the peripheral edge of the part. Thereafter, the front end portion of the locking piece 70 is bent at a right angle by a crease, and the front end portion of the locking piece 70 is inserted into a notch 73 provided in a fold line between the open / close top plate 71 and the open / close top plate front edge piece 72. Then, the open / close top plate 71 is fixed.
In this way, the assembly of the paper box C in which the cold insulator 25 is stored in the equipment storage portion 77 provided on the front plate 62 is completed.

  In addition, in the said Example 1, although it described concretely as a structure of the handle piece 4, the opening-and-closing front-and-back top plates 3 and 9, and each side plate of the paper box A with a handle part, each of the assembly paper box A with a handle part is described. The configuration of the side plate is not limited to this, and other configurations may be used. In the second embodiment, the configuration of the open / close top plate 44 of the box-type paper box B and each side plate is specifically described. However, the configuration of the open / close top plate 44 and each side plate of the box-type paper box B is not limited to this, and other configurations may be used.

  Further, the respective front edges of the left and right inner plates 7 and the inner top plate 34 of the paper boxes A and B are brought into contact with each other, and the one side edges of the bottom plate 1 side or the front plate 32 side are adhered. Are not brought into contact with each other, and the equipment storage portions 26 and 52 may be formed by adhering one side edge of each equipment in a state where they are close enough to prevent the equipment to be stored from falling. Moreover, although the cold insulator 25 was used as what is accommodated in the fixture storage parts 26 and 52, fixtures, such as a candle and a napkin other than the cold insulator 25, can be accommodated. In addition, three circular holes are formed as the through holes 7b and 34b for ventilation in each inner plate 7 and each inner top plate 34. However, the shape and number of the through holes 7b and 34b are appropriately required shapes. It is only necessary to provide a quantity, and, of course, it is not necessary.

  In the second embodiment, the top plate 33 provided with the equipment storage section 52 is folded and tilted toward the bottom surface 31 and supported by the left and right folded left side pieces 36, the folded right side piece 39, and the folded plates 37 and 40. However, the top plate 33 provided with the equipment storage portion 52 may not necessarily be supported by the left and right folded left side pieces 36, the folded right side piece 39, and the folded plates 37 and 40. It may be directly supported by the upper edges of the inner plates 48 and 49 and the left and right outer plates 35 and 38. In this case, the folded left side piece 36, the folded right side piece 39, and the folded plates 37 and 40 are omitted. Good
