Description

  The present invention relates to a cardboard sheet of A4 size, for example, which can cut out a fanned sheet that can produce a fan made of total paper by bending and pasting.

  Fans may be distributed free of charge for advertising at streets, sports, festivals and other venues during hot weather. Many of these paper fans are paper fan that can be mass-produced at low cost. However, a fan that has been assembled as a paper fan is good for advertising, but it is not interesting for the recipient. If it is not assembled and the side you have assembled is a fan, you can make a paper craft fan and enjoy it. In addition, the assembled paper fan is inconvenient to use as a newspaper insert or magazine supplement for advertising purposes. For these reasons, there is a need for cardboard sheets that can be used for newspaper inserts, magazine appendices, etc. in A4 size, and can be used for paper craft fan production by allowing the recipient to assemble a paper fan to assemble a paper fan. .

  Another problem for paper fans is how to ensure the strength of the connection between the fan surface and the handle. For example, in Patent Document 1, a central handle is provided by projecting the lower center of the fan face downward, a reinforcing plate is provided adjacent to both sides of the fan, and it is bonded and fixed to provide an overlapping area. A paper fan in which a protruding area protruding above the overlapping area is reinforced by bonding and fixing has been proposed. However, in the case of this paper fan, it cannot be said that the rigidity of the handle portion is sufficient with three sheets of thick paper, and the strength of the protruding area is also sufficiently ensured with two sheets of thick paper.

  Further, Patent Document 2 discloses that the side edge of the handle gripping portion made of double-ply paperboard of the same shape extends from the side edge of the gripping portion to the upper side of the gripping portion so as to extend obliquely outward and upward from the lateral width of the gripping portion. There has been proposed a paper fan in which connecting portions having a large width are continuously formed, and a base portion of a fan surface is sandwiched between two connecting portions and fixed to each other. However, in the case of this paper fan, there is a problem that it takes time to manufacture because the fan face and the handle are separately manufactured and then assembled.

The fan-folded sheet 3a cut from the cardboard sheet 1a of the present embodiment is different from the fan-folded sheet 3 of the first embodiment in that the second left fold line is formed on the left side of the left reinforcing pattern 8b as shown in FIG. The second left reinforcing pattern 10b having the same shape as the second right reinforcing pattern 10a is connected to 9b. An arc-shaped substantially fan-shaped reinforcing piece 12b extends from the upper edge of the second left reinforcing pattern 10b in the same manner as the second right reinforcing pattern 10a.

  When assembling the fan 2a using the fan-folded sheet 3a, the right fold line 7a and the second right fold line 9a located on the right side of the center handle 6 are, for example, mountain folds, and the left fold line located on the left side of the center handle 6 is left. The crease line 7b and the second left crease line 9b are reversely folded. The folding order is such that the right reinforcing pattern 8a is first folded in a mountain and overlapped on the back side of the central pattern 6, and then the left reinforcing pattern 8b is stacked in a valley and overlapped on the front side of the central pattern 6. Subsequently, the second right reinforcing pattern 10a is overlapped on the left reinforcing pattern 8b by mountain folding, and finally the second left reinforcing pattern 10b is overlapped on the right reinforcing pattern 8a by valley folding. An adhesive is applied in advance to the folded inner surface of each reinforcing pattern, and bonded and fixed in a folded state. A front view and a rear view of the finished product assembled in this way are as shown in FIG.

(Modified embodiment)
In the cardboard sheets 1 and 1a in the first and second embodiments, outline drawings of the fan-fold sheets 3 and 3a for assembling the paper fan 2 and 2a are formed on the sheet by printing. For this reason, scissors are required to separate the fan spread sheets 3 and 3a along the outline, and when they are distributed at the event venue, they cannot be assembled on the spot because there is no scissors.

  In order to solve this problem, it is preferable to form cuts that are interrupted along the contour lines of the fan-folding sheets 3 and 3a so that the fan-rolling sheets 3 and 3a can be separated by hand along the cuts. FIG. 8 is an example in which such intermittent cuts 20 are provided along the contour line of the fan-folded sheet 3b. The fan-folded sheet 3b and the peripheral part of the cardboard sheet 1b are connected to each other only by the narrow connection part 21 having no cuts 20 provided in some places. Since the narrow connection portion 21 can be broken by hand, the fan-folding sheet 3b can be separated without using scissors. In addition, it is easy to assemble by forming an adhesive layer on the part that needs to be bonded and pasting release paper.

  In the drawings, 1, 1a, 1b are cardboard sheets, 3, 3a, 3b are paper round fans, 4 is a fan face, 5 is a handle, 6 is a center handle, 7a, 7b, 9a, 9b are creases, 8a is right The reinforcing pattern, 8b is the left reinforcing pattern, 10a is the second right reinforcing pattern, 10b is the second left reinforcing pattern, 12a and 12b are substantially fan-shaped reinforcing pieces, and 20 and a cut.
