1 is a perspective view of a double box according to an embodiment of the present invention, and FIG. 2 is a perspective view of the inner panel in FIG. The double box 1 shown in FIG. 1 is a so-called sack-attached folding box, which is formed by assembling a blank board 2 made of paperboard whose development is shown in FIG. It has a form in which four sides of the body are doubled.

FIG. 3 shows the inner surface side of the blank plate 2. As can be seen from the drawing, the blank plate 2 comprises an outer component A and an inner component B. The outer component A is provided with a ruled line a
Through c, a wide rear panel 3, a narrow side panel 4, a wide front panel 5, and a narrow side panel 6 are sequentially connected in the horizontal direction, and ruled lines d are formed above and below the side panel 4. , E, a folding panel 7 is provided continuously above and below the side panel 6, and a folding panel 8 is provided continuously above and below the side panel 6, and ruled lines h, i are provided above and below the rear panel 3. Through the inner lid panel 9 and the inner bottom panel 1
0 are continuously provided, and a lid panel 11 and a bottom panel 12 are formed continuously above and below the front panel 5 via ruled lines j and k. Then, the rear panel 3, the side panel 4, the front panel 5, and the side panel 6 are outer panels constituting a trunk when the blank plate 2 is formed in a box shape. On the other hand, the inner portion B has a shape in which panel portions 13 to 16 of the inner panel are continuously provided via ruled lines l to n, and these panel portions 13 to 16 have the vertical dimension of the outer panel. The width of the panel portions 13 to 16 is slightly smaller than the width of the rear panel 3, the side panel 4, the front panel 5, and the side panel 6, respectively. The side panel 6 of the outer component A and the panel portion 13 of the inner component B are connected by a ruled line o.

The front panel 5 is formed with a strip-shaped break 19 which is divided by two rows of perforations 17 and 18 in the upper part thereof. The blank plate 2 is assembled on the right side of the band-shaped break portion 19 by providing a cut 20 connecting both ends of the perforations 17 and 18 in an arc shape so as to cut into the side panel 6 and omitting the ruled line c in this portion. When this is done, this arc-shaped portion is made to be a knob portion, and further, on the left side of the band-shaped break portion 19, a cut 2
1 is provided so that the strip-shaped breaking portion 19 comes off when it is broken along the perforations 17 and 18 from the knob formed by the cut 20. The side panels 4 and 6 are provided with obliquely upward perforations 22 and 23 at positions continuous with the upper perforations 17 of the strip-shaped break portion 19, and the rear panel 3 is provided with perforations 22 of the side panel 4. A horizontal ruled line p is provided at a position which is continuous with the upper part of the box. After the strip-shaped break 19 is removed, the perforations 22 and 23 are broken to open the upper part of the box using the ruled line p as a hinge.

The above-mentioned ruled lines a to k and ruled line o are formed by pressing rules, but the ruled lines 1 to n in the inner constituent part B and the ruled line p in the rear panel 3 are formed by notched lead rules. Easy to bend.

The blank plate 2 having the above-described structure is formed by punching a paper board on which a picture or the like is printed into the shape shown in FIG.
In FIG. 5, an ink containing OP varnish or silicon is printed in a hatched area 23 on the front side of FIG. The printing of the ink containing the OP varnish or silicon is performed subsequent to the printing of a picture or the like. .

The blank plate 2 is sack-attached in a carton factory in the following procedure to form a carton blank. First,
The panel portion 16 is bent inward by the ruled line n, and the panel portions 14 to 16 are bent inward by the ruled line 1 as it is , and the panel portion 16 and the side panel 6 are bonded to each other to obtain a state shown in FIG. Next, a water-soluble glue is applied to the back side of the front panel 5 in a spot shape at a position where the glue enters the area 23 of the panel portion 15, and the side panel 6 and the panel portions 13 to 16 are bent inward at the ruled line c. In the state shown in FIG. 5, finally, the rear panel 3 is bent inward at the ruled line a, and the glue margin 1 at the right end of the panel 13 is formed.
The inner surface of the end of the rear panel 3 is bonded to 3a to form a carton blank shown in FIG. Therefore, at this time, the area 23 on the front side of the panel portion 15 and the back side of the front panel 5 are weakly adhered to each other by spot-shaped glue and are in a state of being adhered.

[0013] After the above-mentioned carton blank is opened in a filling factory, frozen desserts are put therein and sealed. As described above, the front side of the panel portion 15 and the back side of the front panel 5 are in a state of being weakly bonded to each other, so that the bonding positions of the inner panel and the outer panel are shifted.
In the initial stage of the raising operation for raising the carton blank , the panel portion 15 is lifted with the panel portion 15 attached to the front panel 5. And since the panel part 15 separates from the front panel 5 as it is completely raised,
Posting is performed without being restrained.

After raising the carton blank, the lower folding panels 7, 8 are folded, and then the inner bottom panel 10 and the bottom panel 12 are folded in this order and bonded to close the bottom. Then, in this state, the frozen dessert is filled from above and the upper folding panels 7 and 8 are folded in the same manner as when the bottom is closed, and then the inner lid panel 9 and the lid panel 11 are folded and bonded in this order. To close the top.

The double box 1 formed as described above starts with the knob formed by the cut 20 as a starting point.
After tearing and removing 9, the perforations 22 and 23 of the side panels 4 and 6 are broken, and the upper part thereof is opened using the ruled line p of the rear panel as a hinge.

In the above embodiment, an ink containing OP varnish or silicon is printed on the area 23 of the panel portion 15, and a water-soluble paste is applied on the back side of the front panel 5 in the form of a spot to weakly bond the two. However, as another method, a weak adhesive is printed on the front side of the panel portion 15 or the back side of the front panel 5 so that the two are weakly adhered when the blank plate 2 is stuck. You may. In this case, the area on which the weak adhesive is printed is appropriately selected according to the type of the weak adhesive so that both areas come off as the opening proceeds.

Further, the present invention is not limited to the double box provided with the opening means as described above, but may be any conventional box in which a predetermined portion of the inner panel is adhered to the inner surface of the outer panel at the stage of sticking. Needless to say, the present invention can be applied to a double box in a form.

[0018]

As described above, in the double box of the present invention, at the stage of the carton blank before the boxing, the front side of the inner panel is separated from the back side of the outer panel at the time of the boxing. because it is weakly bonded to, the adhesive during storage and transportation of the carton blank
Even if the carton blank is warped and the bonded portion is displaced before it is cured, the bonded portion is separated during the raising operation, so that it is possible to prevent the raising from becoming difficult.
