It is related to the packing paper box that can be sealed by simply pasting the slip.

In recent years, small cargo flights have been developed, and a large amount of cargo flights are distributed every day. In most cases, the contents are stored in a corrugated cardboard box, the lid of the box is sealed with adhesive tape, and a slip such as an invoice is attached.

The most common structure of a cardboard box is a structure in which the inner flaps are folded from the left and right at the opening, the front and rear outer flaps cover the left and right inner flaps, and the front and rear outer flaps are abutted at the center line of the box. Is common. Sealing of such a box is performed by applying adhesive tape to the joints of the front and rear outer flaps.

This structure is widely used because of its simple blank shape and ease of manufacture, but it has some drawbacks. One of them is that when the box is viewed from above, there is no problem if it is square, but in the case of a horizontally long rectangular box, the length of the left and right inner flaps is insufficient, and there is a problem that there is a gap. be. If you try to make the rectangular box long enough to reach the left and right flaps, it will waste a lot of paper, so it is not generally adopted.

If the length of the left and right inner flaps is short, the inner flaps will easily hang down into the box when the box is closed, making it easy to insert objects through the gaps in the outer flaps or insert your hands to open the box. Can be done. For this reason, in the case of a box with such a structure, after closing the outer flap, the seams of the outer flaps should be stapled or adhesive tape should be attached to the seams for safety. It took a lot of trouble to fix the left and right sides of the outer flap with adhesive tape.

The packing box described in Patent Document 1 is designed to solve the above problem, and is a packing box that can be closed without using an adhesive tape or the like and can be unpacked by hand.

In the packaging box described in Patent Document 1, a front plate, a rear plate, a right side plate, and a left side plate are connected in series with the bottom plate as the center, and front and rear inner locking flaps are connected in series from both sides of the left and right side plates. From now on, the front top plate and the back top plate are connected in series, and the top plate can be locked by inserting the closing claws provided on the front top plate into the closing slits provided on the back top plate on the top surface without using adhesive tape or the like. It is designed to be able to be closed.

Hereinafter, the paper box according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic plan view of a blank 4 according to an embodiment of the paper box 1 according to the present invention, and shows a state in which the blank is viewed from the surface side of the box. In the figure, the alternate long and short dash line indicates a mountain fold ruled line, and the dotted line indicates a valley fold ruled line. Further, FIGS. 2 to 7 are perspective explanatory views showing a series of processes from a folded state of the paper box in which the blank of FIG. 1 is made to a state of assembling and finally sealing.

The paper box 1 according to the present invention has a rectangular front plate 5, a right side plate 6, a rear surface plate 7, and a left side plate 8 sequentially connected from the front plate 5 via a fold ruled line. The bottom surface is composed of a bottom member group 17 connected from the front plate 5, the right side plate 6, the rear surface plate 7, and the left side plate 8 via a fold ruled line.

The structure of the bottom surface 3 is not particularly limited, but as in the example shown in the blank of FIG. 1, a stapler or adhesive tape is used as in a one-touch bottom or a so-called hell bottom that can be assembled with one touch. A structure that can be easily assembled without using it is preferable.

A front top plate 9 is continuously provided on the front plate 5 via a fold ruled line, a rear top plate 10 is continuously provided on the rear surface plate 7 via a fold ruled line, and the right side plate 6 and the left side plate 8 are connected with a fold ruled line. The right inner flap 11 and the left inner flap 12 are connected to each other via the above.

Insert pieces 14 and 15 provided via fold ruled lines on the left and right of the tip of the front top plate 9 are inserted into the slits 13 provided in the center of the left and right inner flaps, and are provided in the center of the rear top plate 10. The top surface 2 is closed by inserting the insertion piece 16 under the front top plate 9 and the left and right inner flaps 11 and 12.

At this time, it is preferable to provide a protrusion 25 at the center of the tip of the front top plate 9 so as to press the inserted insertion piece 16 from above.

By attaching an adhesive invoice slip to the joint of the front and rear top plates of the closed top surface 2, the top surface, which is the opening, is completely sealed, so that it adheres to the gap between the top surface and the side plate. It is very efficient because there is no need to attach tape or the like.

As shown in FIG. 6, the slip pasting position mark 21 may be printed in advance at the position where the invoice is pasted on the top surface 2 so that the correct position can be seen.

Note that FIG. 1 shows a state in which the blank is viewed from the surface side of the paper box, the alternate long and short dash line indicates a mountain fold ruled line, and the dotted line indicates a valley fold ruled line. In this example, the glue margin 22 is adhered to the left side plate 8, and the triangular portion of the bottom surface member group 17 divided by the valley fold ruled line is adhered to the adjacent bottom surface member.

It is an important point to insert and fix it.

The insertion pieces 14 and 15 are provided with an overhanging portion 24 on the outside so that the overhanging portion 24 is caught by a dead end portion of the slit and locked. For this reason, the insertion piece has a structure that cannot be easily removed once it is inserted into the slit.

As a result, the left and right inner flaps are held horizontally without hanging inside the box, and articles cannot be inserted through the gap between the top plate and the inner flaps.

By providing an arcuate mountain fold ruled line 18 at the base of the insertion piece 16 provided in the central portion of the rear top plate 10, the insertion piece 16 is inserted under the front top plate 9. 16 tends to warp downward convexly. Therefore, the insertion is performed smoothly.

Further, even after the insertion piece 16 is inserted, the arc-shaped mountain fold ruled line 18 remains in a slightly folded state, so that the flatness of the top surface 2 is improved. This means that when a slip such as an adhesive invoice is attached to the joint of the front and rear top plates, it can be adhered more firmly.

The shape of the arc is preferably such that the distance between the apex of the arc and the start point (end point) of the arc is about 20 to 30 mm.

In the example shown in FIG. 1, the slit 13 provided in the center of the right inner flap 11 and the left inner flap 12 is an insertion piece 14 provided in the right and left of the tip portion of the front top plate 9 via a fold ruled line. The width widens toward the tips of the left and right inner flaps except for the portion where the 15 is inserted.

By doing so, when the insertion piece 16 provided in the central portion of the rear top plate 10 is inserted under the front top plate 9 and the left and right inner flaps 12 and 11, the gap becomes wide and the operation becomes easy. ..

Further, in the example shown in FIG. 1, the opening start point 20 is set at the upper center portion of the front plate 5, and the opening perforation line 19 extending in a V shape toward the bases of the left and right insertion pieces 15 and 14 of the front top plate 9 is formed. It is provided.

By providing such a perforation line, when opening a paper box, it is possible to open the box with one touch starting from the opening start point 20. At this time, the invoice slip attached to the top surface is also removed at the same time, which is extremely efficient.

As the material used for the paper box according to the present invention, various thick papers such as corrugated cardboard of a predetermined flute standard can be used depending on the size of the box and the weight of the contents.
