Abstract

PROBLEM TO BE SOLVED: To provide a packaging box whose lid box is easy to set up, wherein while the lid box is put over a base box, a receive provided inside the lid box in contact with an upper rim of sidewalls of the base box has a sufficient strength. SOLUTION: The packaging box is formed by setting up the base box for receiving an article or the like and the lid box to be put over the base box by folding a piece of paper or the like. Sidewalls of the lid box comprise an external plate and an internal plate folded over the inside thereof. A band plate to be overlaid on the vicinity of an internal surface of a top plate of the lid box is connected with the internal plate. At an end of one of band plates on two sides which vertically intersect with each other on the band plate provided in the vicinity of the internal surface of the top plate, a notch with a length approximately the same as a width of the other band plate is provided, wherein an end of the other band plate can be fitted into the notch. A claw which can be locked with the other band plate is made to protrude from a rim of the notch. In addition, a tab which comes into contact with an upper rim of the sidewalls of the base box while the lid box is put over the base box is formed by slantly folding from the internal plate at a corner inside the lid box. One of side rims of the tab is brought into contact with the band plate.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a packaging box.

[0002]

2. Description of the Related Art Conventionally, a bottom box has been made so that products and the like can be projected upward by lowering a side wall so as to make the goods to be stored stand out, and a lid box to be put on the bottom box is made of paper or the like. A packaging box formed by folding and assembling is known. As described above, in this type of packaging box, since the products and the like protrude above the bottom box, the side wall of the lid box is made higher accordingly. The lid box is provided with a receiving portion at an appropriate height on the inner surface of the side wall and in contact with the upper edge of the side wall of the bottom box in a state where the lid box is put on the bottom box.

[0003] The above-mentioned conventional packaging box, particularly the lid box, has a complaint that it is troublesome to assemble, and also has a complaint that the strength of the receiving portion is insufficient.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a cover box which is easy to assemble, and which is in contact with the upper edge of the side wall of the bottom box in a state where the cover box is placed on the bottom box.

[0005]

In order to solve the above-mentioned problems, a packaging box according to the present invention comprises: a bottom box for storing goods and the like;
A lid box to be put on the bottom box is formed by folding paper or the like and assembled, and the side wall of the lid box is composed of an outer plate and an inner plate folded inside the outer plate. A band-shaped plate is superimposed on the periphery of the inner surface of the top plate of the box, and one end of the two-sided band-shaped plate which intersects the other at right angles in the band-shaped plate arranged on the periphery of the inner surface of the top plate. A notch having substantially the same length as the width of the plate is provided so that the end of the other band-shaped plate can be fitted into the notch, and a claw piece that can be locked to the other band-shaped plate at the edge of the notch. The tongue-shaped piece which is protrudingly provided and abuts on the upper edge of the side wall of the bottom box in a state where the cover box is put on the bottom box is formed by being obliquely bent from the inner plate at the corner inside the cover box, and It is characterized in that one side edge of the tongue-shaped piece is brought into contact with the above-mentioned band-shaped plate.

When the lid box 2 is assembled, the packaging box of the present invention has a front strip 11a, a rear strip 11b, a left strip 7a and a right strip 7b as described above.
Need to be superimposed on the inner peripheral portion of the top plate 4. At this time, the left and right ends of the front band plate 11a and the rear band plate 11b are connected to the left band plate 7a and the right band plate 7b. Notches 18a, 18b, 18 provided at both front and rear ends of
c and 18d, respectively, but only the notches 18a, 18b and 18 of the left band-shaped plate 7a and the right band-shaped plate 7b.
Claw pieces 19a, 19b, 19 projecting from the edges of c, 18d
c and 19d are the front band-shaped plate 11a and the rear band-shaped plate 11b
, It is not necessary to overlap the left and right ends of the front strip 11a and the rear strip 11b with the front and rear ends of the left strip 7a and the right strip 7b. Therefore, there is an advantage that the assembly becomes easy. Further, when the lid box 2 is put on the bottom box 1, the tongue-shaped pieces 20a, 20b, 20c, 20d with which the upper edges of the side walls of the bottom box 1 abut are formed on one side edge 2a.
6a, 26b, 26c, and 26d are in contact with the inner surfaces of the front band-shaped plate 11a and the rear band-shaped plate 11b, which are superimposed on the inner surface of the top plate 3, to maintain the state supported by them. Even if a pressure is applied from above, there is an advantage that it has a strength enough to withstand the pressure and is hard to break.
