[0007] Since the band-shaped mount 3 is attached to the inner surfaces of the films 5 and 5 as described above, the cake mold is protected by the mount 3 when accommodating the cake. Deformation can be prevented.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing one embodiment of a packaging bag for cakes according to the present invention. In FIG. 1, reference numeral 1 denotes a bag-shaped packaging bag main body made of a film of a synthetic resin such as polypropylene. The packaging bag body 1 is overlapped so that the edges of the two films 5, 5 formed in a substantially trapezoidal shape coincide with each other, and both side edges 5b, 5 of the films 5, 5 respectively.
b and one end 5c (corresponding to the short upper side of the trapezoid) 5c are sealed by, for example, a method such as heat welding, and the other end (corresponding to the long lower side of the trapezoid) 5a is opened. Is formed.

Reference numeral 3 denotes a rectangular backing sheet made of a thick material such as a transparent synthetic resin and housed inside the packaging bag body 1.
The length of the mount 3 in the longitudinal direction is substantially the same as the length of the side surface of the cake formed in a substantially fan shape, and the length in the transverse direction is equal to the side 5c corresponding to the upper bottom of the packaging bag body 1. They have approximately the same length. In the backing sheet 3, the backing sheet 3 is folded in two by a fold 3 a so that one side is protruded, and the backing sheet 3 on the side which is folded and protruded is further provided with a fold 3 b.

The length of the backing sheet 3 on the side which is not folded and protruded from the fold 3a is substantially equal to the length corresponding to the radius of the substantially sector-shaped cake. The folds 3a and 3b are provided so that the distance from to the fold 3a is substantially the same as the radius of the fan-shaped cake.
Further, in the mount 3, the length from the fold 3b on the side of the two-folded protruding side to the end has substantially the same length as the portion corresponding to the arc of the substantially fan-shaped cake.

When the mount 3 is accommodated in the packaging bag body 1, the mount 3 is formed with a tapered fold 3a at one end.
5c, which is installed so as to be located at 5c and which corresponds to the radius of the substantially fan-shaped cake (hereinafter referred to as radius) 3c
Is attached to the packaging bag body 1. On the other hand, a backing sheet of approximately the same length as the portion corresponding to the arc of the cake
3d is not adhered to the packaging bag body 1.

A process of using the thus constructed cake packaging bag body 1 according to the present invention to accommodate a cake and form a package will be described. First, the packaging bag body 1 is opened from the front surface of the paper of FIG.
As shown in FIG. 2A, with the packaging bag body 1 in a triangular box shape, a substantially fan-shaped cake is inserted from the opening 6 in FIG.

After inserting the cake, as shown in FIG. 2 (b), the mount 3 is folded with the folds 3a being valley-folded.
By covering a portion corresponding to the arc of the cake 2 with the circular arc portion 3d, the entire side surface of the cake 2 is surrounded by the mount 3.

Next, as shown in FIG. 3, the opening (portion where the cake 2 is inserted) of the packaging bag main body 1 is first bent from the left and right along the circular arc 3d, and then the circular arc is formed from the vertical direction.
The package bag 1 is bent toward 3d, and the folded package bag main body 1 from above and below is fixed to the circular arc portion 3d, and the packaging bag main body 1 containing the cake 2 is adhered so as to be sealed.

In this way, the cake 2 is packed
, So it is not exposed to germs and the like. Therefore, the cake can be kept in a clean state, and the shelf life of the cake is good.

Also, when the cake packaged by the packaging bag body is pinched, the cake is held by the backing paper, so that the cake can be pinched without causing the cake to lose its shape.

Further, since the packaging bag body and the mount are both transparent, the cake can be visually recognized from the outside in a packaged state. Therefore, when the cake is displayed in a showcase or the like, the cake can be arbitrarily arranged at a predetermined position, and the cake is visually appealing to the purchaser.

According to the above-described embodiment, the side of the cake is covered by bending one sheet of paper at a predetermined position. However, the paper of the present invention is not limited to this, and is, for example, used in the above-described embodiment. It is also possible to attach to the packaging bag body a backing sheet in which a portion corresponding to the folded upper bottom is cut in advance. In addition, even if the mount is not attached to the packaging bag main body, if the mount closely adheres to the packaging bag main body due to static electricity or the like,
The mount may be simply incorporated in the packaging bag body.

According to the above-described embodiment, the mount is made of a transparent synthetic resin. However, if the cake is visible from the outside in a state where the cake is covered, the cake can be prevented from being deformed and the cake is clean, For example, it may be translucent or printed. In addition, if the packaging bag body is transparent at least, the cake can be viewed from above, so that the mount need not necessarily be a material that allows the cake to be viewed.

[0020]

According to the packaging bag for cakes of the present invention,
In a packaging bag body in which both side edges of two tapered rectangular films and one end formed in a tapered shape are heat-welded, and an opening is formed in the other end, substantially the same as the one end. Having a length of
