The lid piece (8) is held down from the outer surface so as not to open unintentionally, and the box body (P) is shaped by the insertion locking pieces (9b), (9b), and (9b). Is improved, the opening is hardly deformed, the lid piece is prevented from being protruded due to the deformation of the opening, and the closed state of the lid can be reliably maintained. In addition, the box body (P) By the inner box (R) fitted inside, the shape retention is further improved, the opening is hardly deformed, and the cover piece is prevented from being protruded due to the deformation of the opening. It is possible to more reliably hold.

When the packaged object is to be taken out of the box body (P) in the closed state in this way, as in the first embodiment, the insertion piece (9b) (9b) (9b) 9
b) is pulled out from the insertion holes (11), (11) and (11) to open the polymer piece (9), and then the plug pieces (8b) and (8b) of the lid piece (8) are pulled out to remove the lid piece (8). Open and take out the package from the opening. Alternatively, a break line (19) may be used as shown in FIG. That is, the box body (P) is divided into upper and lower parts by breaking the broken part (19b) of the breaking line (19) with a fingertip or the like, and the upper part (P
1) may be lifted upward, and the article to be packaged may be taken out from the opening. In this case, after taking out a desired number of items to be packaged, the upper part (P1) of the box body is fitted over the exposed upper end portion of the inner box body (R), whereby the lid can be closed.

The packaging paper box shown in the second embodiment has a first window hole (14) formed between the peripheral wall of the box body (P) and the peripheral wall of the inner box body (R). Is a transparent film (40) that plugs in and out freely.
In place of the transparent film (40), a box body (P) for exposing a decoration card (not shown) having animals, plants, landscapes, various patterns, etc. on its surface is exposed from the first window hole (14). ) It may be inserted between the peripheral wall and the inner box (R) peripheral wall. In this case, it is not always necessary to provide the second window hole (38) on the peripheral wall of the inner box (R). That is,
This packaging paper box does not require the use of an adhesive when closing the window hole (14) of the box body with a thin material for closing the window hole made of a transparent film (40), a decoration card, or the like, so that the box body (P ) It is sufficient only to insert between the peripheral wall and the inner box (R) peripheral wall. Therefore, the window-hole closing thin material can be easily attached, and the window-hole closing thin material can be easily replaced. Further, the window-hole closing thin material can be easily taken out and discarded when discarded. It is a packaging paper box that can be easily operated. Note that the packaging paper box capable of exhibiting such an operation and effect only has to be formed in a rectangular cylindrical shape having a box body having a polygonal shape of a triangle or more.

The first and second embodiments have been described above, but the present invention is not limited to these embodiments. For example, the box main body (P) may be a rectangular cylinder having a pentagonal cross section, a seven to ten octagonal cross section, or a polygonal shape having more than that. When the cross section is an odd-numbered polygon such as a pentagon or a heptagon, the overlapping piece (9) is provided continuously on the side wall closer to the opposed arrangement to the side wall on which the lid piece (8) is provided continuously.

Further, in the above two embodiments, the overlapping piece (9) has three insertion locking pieces (9b).
In the present invention, it is only necessary to have at least one insertion locking piece. The number of insertion holes (11) is determined according to the number of the insertion locking pieces (9b).

Further, the present invention provides the box body (P)
The inner box (R) may be fitted inside and the tray (Q) may be inserted. In this case, the shape of the packaging paper box is remarkably improved by the action of the overlapping piece (9), the inner box body (R) and the tray (Q), and the opening is hardly deformed. The projection of the cover piece due to the deformation of the portion is extremely strongly prevented, and the closed state is more reliably maintained.

[0034]

As described above, the packaging paper box according to the present invention has the following effects.

In the packaging paper box according to the first aspect, an outer lid-like superposed piece that is superposed on the outer surface of the lid piece under the closed state is folded at an edge of the side wall substantially opposed to the one side wall. Since it is connected continuously, the overlapping piece can be polymerized so as to hold down the distal end of the lid piece at the base end, and it is ensured that the lid piece jumps out of the distal end and enters the open state. Can be prevented. In addition, the superposed piece has at least one insertion locking piece, and this insertion locking piece is provided at a base hole of the base piece of the cover piece, or at a base end of the inner flap for the cover piece. Since the insertion state is inserted into the provided insertion hole and the state of polymerization with the lid piece is maintained, the lid piece holding action of the above-mentioned polymerization piece can be maintained. In addition, when the lid is in the closed state, the overlapping piece overlaps the outer surface of the lid piece to form a double wall composed of the lid piece and the overlapping piece. The shape is firmly held by the changed lid piece and polymerized piece.
As a result, the shape of the box body is improved, the shape of the opening is less likely to be deformed, the lid piece is prevented from popping out due to the deformation of the opening, and the closed state can be reliably maintained. Furthermore, since the insertion hole is provided near the peripheral wall of the box body such as the base end of the lid piece and the base end of the inner flap for the lid piece, when the insertion locking piece is inserted into the insertion hole, the insertion locking piece is ,

As a result, the box body is further improved in shape retention, and the shape of the opening becomes more difficult to deform,
The protrusion of the lid piece due to the deformation of the opening is strongly prevented,
The closed state can be maintained more reliably.

The packaging paper box according to the second aspect is provided with a box-shaped object-loading tray which is inserted into and out of the box body when the box body is turned sideways. ,
In addition to being able to put the packaged goods in and out, this tray has a bottom wall with a width substantially equal to the width of one side wall of the box body, and a rising angle of a pair of opposed side walls. Since the bottom wall is set to be equal to the inner angle between the side wall of the box body abutting and the side wall adjacent thereto, when inserted into the box body, the bottom wall overlaps the upper surface of one side wall of the box body, and The pair of opposed side walls of the bottom wall can be installed in such a manner as to overlap the inner surfaces of both side walls adjacent to the one side wall. For this reason, the box main body into which such a tray is inserted is reinforced from the inside by a pair of opposing side walls of the tray, and the shape retention is improved, and the opening is hardly deformed. The protrusion of the lid piece due to the deformation of is prevented,
The closed state can be reliably maintained. On the other hand, the tray is installed in a state sandwiched between the side walls of the box body, so that the tray can be installed stably.

According to a third aspect of the present invention, the inner box having the peripheral wall overlapping the inner peripheral surface of the peripheral wall of the box body is fitted in the box body. Will be reinforced by the surrounding wall. As a result, the shape of the box body is much more improved than that of claim 1 or claim 2, and the shape of the opening is less likely to be deformed. As a result, the closed state can be reliably maintained.

[0038] The packaging paper box according to claim 4, wherein at least one of the peripheral wall of the box body and the peripheral wall of the inner box body is provided with a window hole, and a transparent film for closing the window hole from the inside. Since the thin material for closing the window hole made of a decoration card or the like is inserted between the peripheral wall of the box body and the peripheral wall of the inner box body so as to be freely inserted and removed, the thin window material for closing the window hole is closed. When closing with, there is no need to use an adhesive,
It is sufficient only to be inserted between the box body peripheral wall and the inner box body peripheral wall. Therefore, the window-hole closing thin material can be easily attached, and the window-hole closing thin material can be easily replaced. Further, the window-hole closing thin material can be easily taken out and discarded when discarded. It is possible to provide a packaging paper box that can be easily operated.
