Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a packaging box formed of an outer box and an inner box, and particularly relates to the structure of a packaging box in which a movable surface for regulating the inner box is provided on the outer box. .

[Conventional technology]

Conventionally, as shown in FIG.
There is a packaging box to insert and store.

After storing the inner box 3, this packaging box stores the outer box 1.
An adhesive tape 4 is fixed so as to span each surface of the inner box 3 and the inner box 3.

[Problem that the invention attempts to solve]

However, since the outer box 1 is made of paper, there is a problem that once the adhesive tape 4 is removed, the adhesive tape 4 cannot be used again. In addition, the surface of the outer box 1 from which the adhesive tape 4 has been removed is contaminated, resulting in a problem that the appearance of the outer box 1 is spoiled.

Therefore, an object of the present invention is to provide a packaging box that restricts the inner box to the outer box without using a fastening part such as adhesive tape.

[Means to try to solve problems]

According to the present invention, a box body formed in a rectangular shape, one fold line out of four fold lines of this box body, and two faces of the box body connected to this fold line are provided. A pair of notches are provided as shown in FIG. A packaging box characterized in that a movable surface is formed by a crease line connecting the tips of the ends, these notches and the crease line, and a recess is formed in the inner box surface facing this movable surface. is obtained.

〔Example〕

1 to 3 show an embodiment of the present invention. Referring to the drawings, a rectangular cylindrical outer box 5 formed on four sides is provided with a pair of notches 7 extending across two sides connected to one fold line 6. On one side of the outer box 5 where the notches 7 extend, a crease line 8 is provided between the tips of the pair of notches 7 provided thereon. In addition, a pair of tips of the notch 7 extending to the other surface are provided with a notch end 7a that is slightly expanded outward. Fold lines 9 and 10 are provided between each of the notches 7 and the notches 7a at the tip thereof.

In this way, the movable surface 11 formed by the notch 7 has a fold line 12 that is folded along the same line as one fold line 6 of the outer box 5.
In this illustration of the movable surface 11, the folded line is shown as a solid line, and the crease line before being bent is shown as a dotted line.

First, as shown in FIG. 1, movable surfaces 11 are provided on the surfaces of the box bodies 5 that are connected to each other from one fold line 6 of the outer box 5 so as to be flush with those surfaces. .

At this time, the inner box 13 is inserted into the outer box 5. When the inserted inner box 13 is completely housed in the outer box 5, the recess 14 of the inner box 13 is aligned with the outer box 5.
It faces the back surface of the movable surface 11 of. In this state, the fold line 12 of the movable surface 11 located in the same direction as the fold line 6 of the outer box 5 is pushed inward.
Then, the movable surface 11 enters the recess 14 of the inner box 13. At this time, the fold line 10 of the movable surface 11 is bent.

Therefore, since the movable surface 11 enters inside the recess 14 of the inner box 13, movement of the inner box 13 is restricted. When removing the inner box 13 from the outer box 5, if the horizontal plane of the movable surface 11 in the state shown in FIG. 9 is bent and the fold line 1 connects one end of the notch of the movable plate 11
0 protrudes outward. After that, when this fold line 10 is pressed, the fold line 12 of the movable surface 11 is bent in the same direction as the fold line 6 of the outer box 5, and returned to the line of the fold line 6 of the outer box 5. Therefore, the inner box 13 can be taken out from the outer box 5.

In the embodiment, the outer box 5 is made of paper such as cardboard.

Further, the inner box 13 is made of a material such as expanded polystyrene.

[Effect of idea]

According to the present invention, the inner box can be restricted only by the notch in the outer box, and a fastening member is not required, resulting in a simple packaging box.
