DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging paper box with a handle and a packaging paper box with a handle used immediately before packaging of food such as cake.

[0002]

2. Description of the Related Art In a pastry shop, a packing paper box with a handle formed with a bottom wall by combining four bottom wall constituent pieces continuously connected from the lower edges of four side walls has been generally used for a long time. Although it has been widely used, such a packaging paper box with a handle has a risk of bottoming out only by joining the bottom wall constituting pieces together with a tape. Therefore, recently, as shown in FIG. 7 to FIG. 10, the front and rear left and right side walls (52) are attached to the four side edges of the bottom wall (51) of a single plate.
(53) A packaging paper box (B) with a handle of a type in which (54) and (55) are connected in series has been proposed.

[0003] The packaging paper box with a hand (B)
Comprises cover-like connecting pieces (62), (62), (62), and (62) covering the left and right end portions of the left and right side walls (54) and (55), respectively, and the cover-like connecting pieces (62), (62), (62) (62) left and right side walls (54) (5
The box shape is maintained by covering each end of 5).

[0004] A packaging paper box (B) of this type is
Left and right side walls (54)
(55) At both ends of the fall prevention pieces (68) (68) (68) (68)
When the cake is stored in the form of a box, the left and right side walls (54)
(55) is inclined inward, and there is no danger of damaging the cake.

[0005] A pair of handpieces (60) (61) projecting from lid component pieces (56) (57) connected to the upper edges of the front and rear side walls (52) (53) are assembled. Occasionally, the front and rear side walls (5, 5) are provided by the inner flaps (58, 59) connected to the left and right side walls (54, 55)
2) (53) cannot fall down.

[0006]

However, in such a packaging paper box (B) with a handle, the cover-like connecting pieces (62) are connected to the lid forming pieces (56) and (57), and are attached. The attachment pieces (64) are attached to the front and rear side walls (52) and (53). Therefore, in order to manufacture a paper box (B) by bending a required portion from the unfolded state shown in FIG. 8, as shown in FIG. 9, each cover-like connecting piece (62) is formed inside the oblique fold (86). And the lower half (62b) is superimposed on the upper half (62a), and the sticking pieces (64) are attached to the lid constituting pieces (56) (5).
Polymerized on the inner surface of 7), and the adhesive strip (64) or front and rear walls (56) (5
7) After applying the adhesive to the sticking portion of the sticking portion, the cover component pieces (56) and (57) are bent so as to be superposed on the corresponding inner surfaces of the front and rear walls (52) and (53). (64) ... will be stuck on the inner surfaces of the corresponding front and rear walls (52) and (52).

In this case, when bending the lid constituting pieces (56) and (57), the attaching pieces (64) are precisely overlapped with the attaching portions of the corresponding front and rear walls (52) and (53). In order to allow the lower half (62a) of each cover-like connecting piece (62) to be connected to the upper half (62b)
It must be done while holding down strongly. However, since such an operation cannot be performed with the current gluer, the fact is that all the operations are actually performed manually, and the productivity is not very good. Of course,
It is not impossible to manufacture a gluer that can perform the above operation, but the manufacturing cost is considerably high.

[0008] Further, since the cover connecting pieces (62) are covered with the corresponding fall-in prevention pieces (68) by bending the lid constituting pieces (56) and (57), the respective fall-in prevention parts are assembled. This requires an operation of raising the lower end of the piece (68) to the inside of the cover-like connecting piece (62), which is somewhat troublesome.

The present invention has been made in view of the above circumstances, and a first object is to provide a wrapping paper box with a hand which is suitable for machine attachment. A second object is to provide a machine paper attachment box. A third object of the present invention is to provide a packaging paper box with a handle which is suitable and has a side wall which does not fall down.
