[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing box having a lid which can be opened and closed at an upper opening of a box body.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 and 7, an upper opening (b) is provided at one side edge (c) of an upper opening (b) of a box body (a) opened upward. A lid (d) that opens and closes is extended in a freely bendable manner, and a tongue piece (e) bent inward is formed at the tip edge of the lid (d), and the tongue piece (e) is formed. 2. Description of the Related Art There is known a packing box body which is inserted and abutted inside the other side edge (f) of the upper opening (b). The packing box is formed by folding and assembling cardboard paper.

[0003]

However, in the above-mentioned conventional technique, as shown in FIG. 7, a plurality of pieces are stacked in the vertical direction, and a binding band (g) is fastened to the outer periphery in this state to bind the pieces. In this case, the upper packing box pushes the lid (d) of the lower packing box downward, thereby lowering the lower packing box. There is a possibility that they may enter the body, the stacked state may be broken, and the packing box or its contents may be deformed or damaged.

The present invention has been devised in order to solve the above-mentioned problems in the prior art. That is, the problem is that the lid does not enter the box body even when a load is applied from above. It is an object of the present invention to provide a packing box body which is hardly deformed or damaged even when stored or transported in a stacked state.

[0005]

Means for Solving the Problems The packing box of the present invention is:
A lid that opens and closes the upper opening is foldably extended at one side edge of the upper opening of the box body that is opened upward, and a tongue piece bent inward at a tip edge of the lid. In the packing box body in which the tongue piece is inserted and abutted inside the other side edge of the upper opening, a stopper piece for abutting the lower end of the tongue piece is formed. The above-mentioned problem has been solved by projecting from the inner wall surface of the box body.

[0006]

In the packing box of the present invention, a lid for opening and closing the upper opening is provided on one side edge of the upper opening of the box main body opened upward to bend freely. A tongue portion bent inward at the tip edge of the tongue portion so that the tongue portion is inserted into contact with the inside of the other side edge of the upper opening; Since the stop piece that stops the lower end of the piece is projected from the inner wall surface of the box main body, even if a load is applied from above, the lower end of the tongue piece will stop on the stop piece, The lid does not enter the box body, and therefore, even when stored or transported in a stacked state, the stacked state is less likely to collapse, deform, or break itself.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A packing box shown in FIGS. 1 and 2 is an embodiment of the present invention, in which an upper opening 2 is provided at one side edge 3 of the upper opening 2 of a box body 1 which is opened upward. A lid 4 that opens and closes is extended in a freely bendable manner, and a tongue piece 5 bent inward at the tip edge of the lid 4.
And the tongue piece 5 is connected to the other side edge 6 of the upper opening 2.
In the packing box body to be inserted and abutted inside the box body, a locking piece 7 for locking the lower end of the tongue piece 5 is provided to protrude from the inner wall surface of the box body 1.

The packing box is for storing and packing rain gutter fittings, and is formed in a rectangular box shape by folding and assembling corrugated paper.

The side wall portion 8 of the box body 1 on the other side edge 6 to which the tongue piece portion 5 contacts is formed in a double wall structure in which the cardboard paper is folded inward and becomes strong. On the inner wall surface of the side wall portion 8, a plurality of abutting pieces 7 are arranged and protruded horizontally.

The height of the corresponding stopper 7 is such that the upper end of the side wall 8 extends inward and downward by the width of the tongue 5. Further, the corresponding stopper piece 7 is formed by partially cutting and raising only the inner wall part of the side wall part 8 of the double wall structure, and its existence is not known from the outside of the box body 1. is there.

Therefore, in the packing box of this embodiment, a tongue piece 5 is provided at the leading edge of the lid 4 that opens and closes the upper opening 2 of the box body 1. Since the stop piece 7 to be stopped protrudes from the inner wall surface of the side wall 8 of the box body 1, even if a load is applied from above, the lower end of the tongue piece 5 stops on the stop piece 7. As a result, the lid 4 does not enter the upper opening 2 of the box main body 1, and therefore, even if the lid 4 is stored or transported in a stacked state, the stacked state is broken or deformed. It is hard to be damaged.

In the packing box of the embodiment, as shown in FIG. 3, if the binding band 9 is hung in the direction intersecting the opening and closing direction of the lid 4, the stacking state is further broken. It will be difficult.

The packing box according to the present invention may have a configuration as shown in FIGS. 4 and 5. That is, in the packing box body of this embodiment, the band-shaped paper plate member 10 is adhered and fixed to the inner wall surface of the box body 1 on the other side edge 6 side where the tongue piece portion 5 contacts. The upper edge portion is bent inward, and a stop piece 7 is provided over the entire length. One side edge 3 of the upper opening 2 of the box body 1
And on the side edges on both sides other than the other side edge 6 opposed thereto,
An auxiliary tongue piece 11 that can be bent inward and outward extends in opposition, and the two auxiliary tongue pieces 11 are folded under the lid 4 when the lid 4 is closed. Things.

[0014]

As described above, in the packing box of the present invention, a tongue piece is provided at the leading edge of the lid for opening and closing the upper opening of the box body, and the lower end of the tongue piece is stopped. The tongue piece is projected from the inner wall surface of the box body, so that even if a load is applied from above, the lower end of the tongue piece abuts on the tongue piece, and the lid body is inside the box body. It does not penetrate, and therefore, even when stored or transported in a stacked state, the stacked state is less likely to collapse, deform or break itself.
