Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a packaging box for packaging electronic devices, etc.

(b) Conventional technology Conventionally, this type of packaging box was manufactured by Jikkosho, for example.
There is one such as that disclosed in Publication No. 58-24817.

As shown in FIG. 3, this conventional example has insert pieces 2, 2, 2,
2 to the inner flap 3, the notch 4 provided in the 3,
It is sealed by inserting it into 4, 4, 4.

However, in the case of the above conventional example, the insertion piece 2,
2, 2, 2, the area for pressing the inner flaps 3, 3 of the outer flaps 1, 1 is small.
are bent, so the inner and outer flaps 1, 1, 3,
3 has the disadvantage that it opens easily.

(c) Problems to be solved by the invention The present invention has been devised in view of the above-mentioned drawbacks of the conventional examples. The purpose is to provide

(d) Means for solving the problem A box body with an opening, an outer flap with a support piece that is bendable at the tip and from which insertion pieces extend from both ends of the base side, and an insertion hole on the base side. The support piece is bent outward, the insertion piece is inserted into the insertion hole, and the support piece is extended to seal it.

(E) Function As described above, when the support piece is bent outward, the insertion piece is inserted into the insertion hole, and the support piece is extended to seal the seal, the inner flap is pressed by the support piece, and the insertion piece is Since it is inserted toward the base side of the outer flap, the outer flap does not easily come off, and moreover, the flap can be easily opened and closed.

(F) Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the packaging box of this embodiment. The packaging box of this embodiment consists of a rectangular parallelepiped box body 6 having an opening on the top surface, inner flaps 7, 7, and outer flaps 8, 8 that cover the opening. Notches 9, 9, 9, 9 are formed on both sides of the tips of the outer flaps 8, 8, and support pieces 10, 10 having the same width as the outer flaps 8, 8 are formed at the center of the tips, respectively. . From both sides of the base side of the support pieces 10, 10, insert pieces 11, 11, 11, 11 are inserted so as to fit into the cutouts 9, 9, 9, 9.
extend toward the base of the outer flaps 8,8. Further, the support pieces 10, 10 can be bent at the connecting portions 12, 12 with the outer flaps 8, 8. Insertion holes 13, 13, 13, 13 are formed at the bases of the inner flaps 7, 7 at positions where the insertion pieces 11, 11, 11, 11 abut.

Next, a method of sealing the packaging box will be explained. First, the inner flaps 7, 7 are folded inward, and then, while bending the supporting pieces 10, 10 outward,
Fold the outer flaps 8, 8 inward, and
As shown in the insert pieces 11, 11, 11, 1
1 into the insertion holes 13, 13, 13, 13. Next, as shown in FIG. 2b, the support piece 1
0 and 10 are extended so as to come into contact with the upper surfaces of the inner flaps 7 and 7. As a result, the insertion piece 1
1, 11, 11, 11 abut against the inner surface of the inner flap toward the base of the outer flaps 8, 8, and the packaging box is sealed. At this time, the support piece 1
0 and 10 prevent the inner flaps 8 and 8 from floating. Moreover, when the support pieces 10, 10 are bent outward when opening the package, the insertion pieces 11, 11, 11,
11 becomes as shown in FIG.
3, 13, 13, and the outer flaps 8, 8 can be easily opened.

In the packaging box as described above, the insert pieces 11,1
1, 11, 11 into insertion holes 13, 13, 13, 13
and insert the supporting pieces 10, 10 into the inner flaps 7, 7.
It can be sealed by a simple operation of extending it so as to make contact with the upper surface of the supporting piece 1.
0, 10 prevent the inner flaps 7, 7 from floating, and the insertion pieces 11, 11, 11, 11 are inserted toward the bases of the outer flaps 8, 8, and are aligned with the opening direction of the outer flaps 8, 8. are locked in the opposite direction, so that the insertion pieces 11, 11, 11, 11 are difficult to come out of the insertion holes 13, 13, 13, 13, and the inner and outer flaps 7, 7, 8, 8 naturally move. It can prevent it from opening.

(g) Effects of the invention According to the invention, sealing can be achieved by simply inserting the insertion piece into the insertion hole and extending the support piece so that it comes into contact with the upper surface of the inner flap. This prevents the inner flap from floating and locks the insertion piece in the insertion hole corresponding one-to-one with the insertion piece in the opposite direction to the opening direction of the outer flap.
To provide a packaging box in which the looseness of an insertion piece is small, the engagement strength is not weakened even if the insertion piece is bent after being opened and closed many times, and the flap is prevented from opening naturally.
