  However, in the embodiment shown in FIGS. 7 to 13 of Patent Document 1, the storage portion such as the cold insulation material is formed by a single piece of paper, but the contents of the packaging box are used regardless of whether or not the storage portion such as the cold insulation material is used. There is a problem that a storage space that narrows the product is necessarily formed, and depending on the type of cake to be stored, two types of packaging boxes must be prepared at the shop floor etc. due to the nonuse of cold insulation material, and the cost It was high.

In Patent Document 2, since the cold insulation material storage plates 36 and 37 are provided between the upper edge of the side wall and the locking pieces 38 and 39, in order to ensure a sufficient storage space in the cold insulation material storage portion, the top plate portion 48 and 49 and the bottom plate portions 56 and 57 need to have a wide width, which requires a lot of paper and increases the cost. In addition, since it has a structure in which the locking piece is pulled out from the inside through a plurality of folds, there is a problem that field work at a storefront or the like becomes complicated.
The present invention is intended to solve or improve these problems.

  The pocket structure of the packaging box with a handle of the present invention for solving the above-mentioned problem is as follows. First, peripheral walls 3a, 3b, 4a, 4b are continuously provided on each side of the bottom plate 2 having a polygonal shape in plan view so that it can be bent and undulated. In the packaging box 1 in which the top plate 6 constituting the lid is connected to the upper end of the peripheral wall so as to be raised and lowered, the flap 22a can be folded so as to overlap the inner surface of the top plate 6 on the side of the top plate 6. , 22b are connected in series, and the free ends of the flaps 22a, 22b are connected and fixed to the top plate 6 side, thereby forming a pocket 29 for storing the cold insulation material 41 and other equipment on the inner surface side of the top plate 6. It is characterized by.

  Second, the flaps 22a and 22b are connected to both sides of the top plate 6, and the free ends of the flaps 22a and 22b are bonded and fixed to each other.

  Thirdly, a cutout lid 24 that can be removed afterwards and partially is formed so that the cold air of the cold insulation material 41 flows into the flaps 22a and 22b.

  Fourth, the installation position of the cutout lid 24 is provided at a position overlapping the uncut portion of the handle 19 on the top plate 6 side.

  Fifth, an upper flap 12b that is bent inwardly and horizontally and receives the top plate 6 is connected to the upper ends of the side walls 4a and 4b, which are peripheral walls corresponding to the sides of the top plate 6, The free end of the flap 12b is formed in an arc shape.

Therefore, it can be manufactured through a series of processes from cutting to gluing and shipping, and can be manufactured at substantially the same manufacturing cost as a conventional product. Furthermore, since the storage pockets are already formed at the time of shipment, it is only necessary to assemble the packaging box at the shop floor or the like, and the workability can be improved.

(2) Since the flaps are folded inward from both sides of the top plate to form a storage pocket, the strength of the top plate is increased and the handling of stacking and the like after assembling is facilitated. .

(3) Since the storage pocket for the cold insulation material is formed inside the top plate, the volume of the packaging box is hardly reduced, and the current cake tray size can be maintained. .

(4) Since a post-removable and partially removable cutout cover is provided inside the pocket, and the cutout cover is peeled off, a vent hole can be formed as a passage for the cold air. Can be spread. Moreover, since the cut-out lid is configured to be removable as required, other equipment such as a candle other than the cold insulation material can be accommodated in the pocket.

(5) Since the top of the upper flap at the top of the left and right side walls is formed in an arc shape, the bending shape of the top plate inner surface and the arc shape of the flap end when the packaging box is lifted with a handle fit each other Generation of a gap on the lower surface of the lid is prevented.
