DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings.

In the packaging paper box (A) according to the first embodiment shown in FIGS. 1 to 4, (1) is a four-sided side wall (2) (3)
(4) A box body in which (5) is connected in series horizontally, (6)
Is a rectangular tubular partition provided in the box body (1),
(7) is a buffer space formed between the partition (3) and the box body (1).

[0008] The rectangular tubular partition body (6) is formed by combining a pair of partition body main pieces (8) and (8) having the same shape and the same size. A longitudinal fold (21) is provided at a central portion in the length direction to be divided into two side walls (9) and (10), and a band-like joint piece (11) is provided at both ends via folds (22) and (23). (12) are continuously provided, and the corresponding joining pieces (11), (11), and (12) are provided at both ends.
And (12) are superposed and bonded together, and the joining pieces (11) and (11) at one end are formed on the corners of the box body (1) at the corresponding corners of the side walls (2) and (5) of the box body (1). Are connected to the side end of the box through folds (24) and (24), and can be assembled and folded according to the assembling and folding operation of the box body (1). On the other hand, the corresponding joining piece (11) at the other end
(11) The edge is the corner under the assembled state.
It is made to come into contact with the opposing corner with.

[0013] (13) (13) are lid pieces which are provided on both upper and lower edges of one side wall (4) of the box body (1) through folds (25) and (25), and are provided with inward ends. Folded piece (13a) (13
a) are continuously provided via folds (28) and (28).
(14), (14), (14), and (14) are folds (26), (26), (2) at the upper and lower edges of the other pair of side walls (3), (5).
6) Inner flaps connected via (26).
(15), (15), (15) and (15) are through holes simulating an alphabet formed in the center of each side wall (2) (3) (4) (5) of the box body (1). The outer surface of the partition (6) can be seen from the outside when the lid is closed.

[0010] The packaging paper box (A) having the above-mentioned structure is arranged side by side in a developed state as shown in FIG. )
The joining piece (11), the side wall (9), the side wall (10), and the joining piece (12) of the partition body (8) are sequentially provided on the right side of (5), while the joining piece (11) is provided on the left side. The side wall (9), the side wall (10), and the joint piece (12) are sequentially provided. In order to assemble the packaging paper box from this expanded state, first, the pair of partition body main pieces (8) and (8) are joined together with the joining pieces (11) and (12) from the folds (24) and (24) through the side walls (2) and (2). 3)
(4) Bending to the inner surface (back surface of the developed view) side of (5),
From the fold (27) between the side walls (3) and (4), the side walls (2) and (3) are placed on the inner surface side of the side walls (4) and (5) to form a pair of partition main body pieces (8) and (8). Are folded back in a manner sandwiching them, and the corresponding joint pieces (11), (11), (12)
And (12) are adhered to make the whole a flat folded state. Until it is used, it is stored and transported in this flat folded state.

When a force is applied from the opposite direction as shown by arrows A and B in FIG. 2 during use, the box body (1) is automatically assembled into a box form from the folded state. In this process, as shown in FIG. 3, the ends of the joining pieces (12) (12) at one end of the partition (6) are connected to the corners of the box body (1).
, The partition body (6) is also automatically assembled into a rectangular tube shape. Then, by closing one opening with the bottom cover piece (13), the expected assembled state shown in FIG. 1 is obtained. Thereafter, the article to be packaged is stored in the rectangular tubular partition (6), and the upper opening of the box body (1) is closed with the upper lid piece (1).
