Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a flap locking device for a packaging box, and more particularly to a flap locking device that locks a flap that serves as a lid when a cardboard box that has been used once is reused as a storage case.

[Prior art and its problems]

Cardboard boxes are used for packaging of goods. Cardboard boxes are often strong and reasonably sized, and are reused for housing seasonal items at home or used clothes. In this case, a tape or string is used to close the flap that serves as the lid. In the case of a tape, once it is peeled off to take out the contents, it cannot be reused, and it remains dirty after peeling, which makes it dirty. In the case of a string, this is not the case, but it is troublesome to tie or tie the string.

[The purpose of the device]

SUMMARY OF THE INVENTION An object of the present invention is to provide a locking tool that can easily open and close a flap that serves as a lid for a packaging box.

[Constitution of device]

The configuration of the device devised to achieve the above object is as follows. That is, the present invention is for locking the flaps of a packaging box in which a pair of flaps serving as lids are arranged face to face, and the lower flaps located below the flaps when the flaps are closed. One side of the lower piece by connecting a fixed upper piece arranged on the upper side of one side of the lower piece and the lower piece with a connecting body formed near the tip edge of the flap. And a flap fitting insertion portion formed by a connecting body and a fixed upper piece, the fixed upper piece, a movable upper piece that is moved from the fixed upper piece side to the upper part of the other side of the lower piece is provided, One of the flaps is clamped by the flap fitting portion, and the other of the flaps is clamped by the movable upper piece and the other side of the lower piece.
It is a flap locking device for a packaging box. Action / Effect First, one flap is fitted and sandwiched in the flap fitting and inserting portion. Next, the other side of the lower piece is installed horizontally, the other side of the flap is covered to close the opening of the box, and then the movable upper piece is moved to the upper part of the other side of the lower piece. This closes the flap and acts as a lid for the packaging box.

【Example】

The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a perspective view showing the first embodiment. In the packaging box, a pair of flaps F1 and F2, which serve as lids, are arranged so that their leading edges face each other. When the flaps F1 and F2 are closed, the respective flaps F
It has a lower piece 10 located below 1, F2. A fixed upper piece 11 is arranged on the upper side of one side 10a of the lower piece 10. The fixed upper piece 11 and the lower piece 10 are connected by a connecting body 12 formed near the tip edges of the flaps F1 and F2, and the one side 10a of the lower piece, the connecting body 12, and the fixed upper piece 11 are connected. A flap fitting portion 13 surrounded by is formed. On both sides of the fixed upper piece 11, a guide body 11a having a "U" -shaped cross section,
11b is formed, and the movable upper piece 14 is movably fitted to the guide bodies 11a and 11b. The movable upper piece 14 moves from the fixed upper piece side to the upper part of the other side 10b of the lower piece. 15 is a stopper that doubles as a knob. Operation First, one flap F1 is inserted into the flap insertion portion 13 and sandwiched. Next, install the other side 10b of the lower piece horizontally and set the other flap F
After covering the opening of the packing box with 2
Is moved to the upper part of the other side 10b of the lower piece. This closes the flaps F1 and F2 and functions as a lid for the packaging box. FIG. 2 is a perspective view showing a second embodiment of the present invention.
The difference from the first embodiment is that the movable upper piece 14 is a slide type in the first embodiment, whereas it is a rotary type in the present embodiment, and accordingly, the movable upper piece 24 is Fixed upper piece
It is rotatably attached to 21 by a pin 20. In addition,
The pin 20 also functions as a connection body between the fixed upper piece 21 and the lower piece 10. A stopper pin 25 controls the movement of the movable upper piece 24. 1 and 2, the same or equivalent parts are designated by the same reference numerals. Further, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims for utility model registration.

[Effect of device]

According to the present invention, a pair of flaps serving as lids are arranged to face each other, and the flaps of the packaging box are locked to each other. When the flaps are closed, the lower flaps located below the flaps are closed. One side of the lower piece by connecting a fixed upper piece arranged on the upper side of one side of the lower piece and the lower piece with a connecting body formed near the tip edge of the flap. A connecting piece and a fixed upper piece formed by a fixed upper piece, the fixed upper piece is provided with a movable upper piece that moves from the fixed upper piece side to the upper part of the other side of the lower piece, Since one of the flaps is clamped by the flap fitting portion and the other of the flaps is clamped by the other side of the movable upper piece and the lower piece, opening and closing of the flap that serves as the lid of the packaging box is easy. A lock can be provided.
