As a result, a semicircular tongue piece 11 is formed. Both ends of the cut portion 10 are slightly inserted into the bottom surface portion 4.
Further, cut portions 12a and 12b, which are continuous with the cut portion 10 and have a slight length, are provided along the fold portion 7a. Further, folds 7a ′ for bending the tongue piece 11 along the front face portion 8a are formed so as to connect both ends of the cut portion 10.

To assemble the inner box 1, side parts 6a, 6
b, the front face portion 8a, the rear face portion 8b, and the glue margins 9a to 9d are bent outward at portions such as the folds 5a, 5b, 7a, and 7b, and an adhesive agent is applied to the glue margins 9a to 9d. , 9b on the inner surface of the front face portion 8a, and the glue allowances 9c, 9d.
Are bonded to the inner surface of the rear surface portion 8b. As a result, the inner box 1 composed of a rectangular container as shown in FIG. 2 is formed. Since the folds 7a 'of the tongue 11 are slightly displaced toward the bottom surface 4 side, the upper end of the tongue 11 is in contact with the peripheral edge of the cut portion 10 on the inner surface of the front surface 8a. It does not project to the front of the portion 8a.

Next, the structure of the outer box 2 will be described with reference to the development view of FIG. The material of the outer box 2 is also formed by punching out cardboard as in the inner box. A left side surface portion 15a is provided on one side surface of a rectangular bottom surface portion 13 via a fold portion 14a, and a fold portion 14b is formed on the other side surface. Through the right side 15
b, the right side surface portion 15b is provided with an upper surface portion 17 via the fold portion 16, and the upper surface portion 17 is provided with a fold portion 18
A glue allowance 19 is provided through. A bent piece 21 is provided at the front end of the bottom surface portion 13 via the fold portion 20, and an insertion piece 23 that can be cut and raised from the bent piece 21 by the cut portion 22 connects the bottom surface portion 13 and the fold portion 20 ′. It is connected through. In addition, the bottom surface portion 13,
A notch 24 that is continuous with the notch 22 and extends toward the rear side surface is provided, and a fold portion 25 that connects both ends of the notch 24 is provided. Notch 24 and fold 2
A portion 26 surrounded by 0 ′ and 25 is an operation piece connected to the insertion piece 23. The folds 20 'are slightly displaced from the folds 20 toward the bottom surface 13 side, and between the folds 20 and 20', the insertion piece 23 is inserted from the folds 20.
A notch 27 that is offset to the side is provided. Also, the upper surface portion 1
7 shows a discontinuous cut line 28 for disassembling the outer box.
a and 28b are provided. Perforations may be provided instead of these cut lines.

To assemble the outer box, the material shown in FIG. 8 is bent so that the folds 14a, 14b, 16 and 17 are on the outside, and the glue margin 19 is adhered to the inside of the left side surface 15a with an adhesive. . As a result, as shown in FIGS. 3 and 4 in which the square tube is laid down sideways, the outer box 1 with the front and rear surfaces opened is formed. In addition, the notches 29a provided in the front surface portions of the left and right side surface portions 15a, 15b,
When the inner box 1 is put in and taken out of the outer box 2, 29b makes it easy to grasp the side surface of the inner box with a fingertip.

Next, a method of fixing the inner box 1 in the outer box 2 will be described. FIG. 3 shows a state in which the bending piece 21 and the insertion piece 23 connected to the bottom surface portion 13 are opened to the outside. Next, as shown in FIG. 4, the bending piece 21 is bent inward at the fold portion 20 and the bottom surface portion 13 is overlapped with the insertion piece 23 left as it is. In this state, the inner box 1 accommodating the dry battery 3 is inserted into the front opening of the outer box 2 from the rear surface portion 8b side. Then, the operating piece 26 is bent outward at the fold portion 25 while pressing the inserting piece 23 downward at the fold portion 20 'by bending the inserting piece 23 inward at the fold portion 20', and then the inserting piece 23 is pressed downward. 23 is inserted into the notch portion 10 of the front surface portion 8a of the inner box 1 by pushing the tongue piece 11 inward. Then, by pushing the lower surface of the operation piece 26 upward, the insertion piece 23 is completely inserted into the inner box 1. In this state, the insertion piece 23 that is folded at the fold line portion 20 ′ and is partitioned by the cutout portions 22 and 27 has the cutout portions 10 and 12 a, 12 b of the inner box 1.
Is plugged into. This state is shown in FIG.
FIG. 5 corresponds to a sectional view taken along line VV ′ in FIG.

Here, the front portion side of the inner box 1 is placed on a bending piece 21 that is stacked on the bottom surface portion 13 of the outer box. Therefore, when a force is applied to the inner box 1 in the X direction of FIG. 5 to push it out of the outer box 2, the front side of the inner box 1 is slightly upward, so that the force in the X direction is increased. Is a slightly upward force as shown by arrow A. Therefore, the insertion piece 23
The inner box sandwiching between the front part 8a and the tongue piece 11 works to lift the insertion piece 23 upward. Therefore, the insertion piece 23 is less likely to come off the cut portion 10. Further, when the operation piece 26 connected to the insertion piece 23 is lifted upward from the fold portion 25 when a force in the direction opposite to the arrow X is applied to the inner box 1, the insertion piece 23 becomes
The notch part 1 can be easily slid on the inner surface of the inner box front part 8a
It deviates from 0. However, the bending piece 21 is the operation piece 2
Since the operation piece 26 does not move because it is placed on 6 and pressed down, the insertion piece 23 is easily moved even if the inner box 1 is pushed in the direction opposite to X from the outer box. Does not come off from the notch 10.

As described above, the inner box 1 can be firmly fixed in the outer box 2 by a simple structure in which the insertion piece 23 provided in the outer box is inserted into the notch 10 of the inner box front surface 8a. Therefore, if the inner box 1 accommodating a predetermined number of dry cells 3 is inserted into the outer box 2 and fixed by the insertion piece 23, it can be transported as an outer box in which a predetermined number of dry cells are packaged. This outer box is carried into the store, and the center of the end of the outer box upper surface portion 17 is pinched with fingers, and the discontinuous cut row 2
The outer box is disassembled if separated at 8a and 28b. Then, if the inner box 1 is lifted up as it is, it can be removed from the outer box, so that it can be displayed at the store. In this packaging box, since the height of the inner box 1 is low, it can be seen that the product in the inner box is a dry battery in a state where the inner box and the outer box are combined. Therefore, it is possible not only to display the product in the inner box with the outer box removed, but also to display the product in a state in which the inner box and the outer box are combined. In that case, if a predetermined number of batteries are handed to the customer without unpacking, packaging is not necessary.

In the above embodiment, the U-shaped bending piece 21 and the inserting piece 2 are formed by providing the notch 22 in the piece connected to the front end of the bottom 13 of the outer box through the fold.
Formed 3. Further, the pair of notches 24 provided on the bottom surface portion 13 are inclined toward the rear side surface so that the operation piece 26 has a slightly wider rear portion. According to this structure, the operation piece 26 is reliably pressed by the U-shaped bent piece 21 and is not likely to be raised upward. However, if the width of the operation piece 26 is increased, the bending piece 21
May not be U-shaped but may be separated into two. Further, in the above-described embodiment, notches 27 are provided on both sides of the root of the insertion piece 23 of the outer case 2, while the insertion piece 23 of the inner case 1 is provided.
The semi-circular cut portion 10 and the cut portion 1 provided at both ends thereof are slightly offset from the folds 7a '.
2a, 12b. Therefore, the insertion piece 2
When 3 is inserted into the above-mentioned notch, it is possible to obtain an effect that the notch 23 becomes hard to come off due to the engagement relationship between the left and right ends of the root of the notch 23 and the notches 12a and 12b. However, it is not always necessary to have such a structure. The notch 27 may be eliminated and the notch into which the insert piece 23 is inserted may have a semi-circular shape.

[0016]

The packaging box of the present invention can be used as an outer box for packing a unit number of products by combining the inner box and the outer box, and the products can be displayed as they are if the outer box is disassembled. It can be used as a display box. Also,
Since the inner box can be formed as a box for exhibition from the beginning, it does not have a bad appearance such as a cut mark at the fold line. Furthermore, since the inner box and the outer box can be fixed in only one place,
The inner box and the outer box can be easily combined and can be manufactured at low cost.
