Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that the side walls and the front and rear walls are formed as double walls,
The present invention relates to a folding paper box that does not require a large volume for transportation, storage, etc., and the box body can be easily assembled from a lying state.

This type of paper box is known from Utility Model Publication No. 49-26584 (Utility Model Registration No. 1080101). In this known paper box, the extended edges of the side walls and the front and back walls are pasted and overlapped on the top surface of the bottom seen from the opening, and the state of the joints cannot be said to be aesthetically pleasing. In addition, with this paper box, the side walls and front and rear walls are slightly bent inward from the upright position, and cannot be made wider than the bottom width of the opening edge, making it impossible to stack the box bodies one above the other once assembled. It was hot.

The object of the present invention is that the extensions of the side walls and the front and back walls are attached and overlapped to the rear surface of the raised bottom, and the extensions are not visible from the opening, resulting in a good appearance. To provide a folding paper box with a double peripheral wall structure and a raised bottom type, in which a large number of box bodies can be stacked one on top of the other after assembly. A box with a body shape similar to that of the present invention is known from Japanese Utility Model Application No. 51-153026, but since this box is not assembled from a lying position, it is different in terms of purpose and function of the present invention. This will be clear from the explanation below.

Next, a preferred embodiment of the present invention will be explained with reference to all the drawings. Figure 1 shows an example of the spread paper pattern of the present invention as seen from the back side of the raised bottom part 1. An inner end 11, an outer end 12, a raised bottom inner end 1i', and a bottom back straight overlapping part 13 are connected to each other via fold lines 8, 9, 10' and 10 in the front and back, and a pair of double folds are formed in the front and back. The walls are folded. In addition, on the Q side, the inner wall part 5, the outer wall part 6, the raised bottom inner wall part and the bottom back pasting part 7 are connected through the fold line 2.3.4 (4), and a set of double walls is formed on the left and right sides. Further, a shaft coupling portion 15 or 16, or 15.16 is attached to at least one of the side inner wall portion 5 and the outer end portion 6. Note that, as shown in the illustrated example, the inner wall portion It is desirable to set the gluing section to 5. In that case, the side double wall 5.6
is copolymerized and does not leave any gaps. For this purpose, a gluing section may be provided on the outer wall section 6. Notches 18 are set at both ends of the pasting part 7, and during assembly,
Both ends of the front and rear bottom-back direct overlapping parts 13 are fixed. However, this effect may be achieved using other known side fastening means.

According to the invention, with respect to FIG.
The inner wall part 5 and the outer wall part 6 are overlapped on the upper surface (the back side in the drawing) of the bottom part 1 through the As shown in FIG. 2), the sticking part 7 is thereby rotated through the fold line 4 and stuck and fixed to the back side edge of the bottom part 1, and this state is shown in FIG. In this way, the left and right side walls are
It is folded down on the upper and lower surfaces of the bottom part 1, and the whole is formed into a flat body. According to another embodiment, the end walls 12.1f, 13 are folded down onto the back side of the bottom part 1 via the front and rear fold lines 9 in FIG. can.

The assembly is as follows.

As shown in FIG. 3, the side wall 6 folded down on the upper surface side of the bottom part 1 is erected with the fold line 4' on the lower surface side as the rotation axis, and The inner end 11 is folded up, and a shaft coupling part 15.16 is attached to the back side of the folded inner end 11.
Then, as shown in FIG. 4, bend these along the fold lines 8' and 8'' so that Bend the top piece as shown in the arrow, then fold the raised bottom inner end 1A and bottom back overlapped part 13 through fold line #!10' [F] Finally, fold the bottom back overlap through crease line 10. The portion 13 is bent and abuts and overlaps the position indicated by the dashed line, that is, the upper and lower edges of the back surface of the raised bottom portion 1, and both ends of the overlapping portion 13 form cutout portions 18 provided at both ends of the adhesive portion 7. By such a simple operation, a box as shown in FIGS. 5 and 6 can be obtained.

In the design according to the present invention, as shown in FIG. 1, if the edge lines and folding lines 8' and pi of the inner and outer ends 11, 12 are provided with appropriate slopes, as shown in FIGS. 5 and 6, Thus, it is possible to obtain a box with a wide opening. In this case, a large number of boxes once assembled are stacked one on top of the other, which is convenient because space can be saved.

Furthermore, according to the present invention, continuous production can be performed mechanically instead of by hand folding. Turn the unfolded paper mold shown in FIG. 1 upside down, that is, with the bottom 1 facing upward. A belt fold is applied through the fold line 2.3, overlapping the inner and outer walls 5.6 and folding it down on the upper surface of the bottom part 1, after which the whole is turned over 180 degrees and is folded along the dashed line in FIG. Then, attach 9 to the attachment part 7 with a coaster or the like, and then fold the belt along the crease line 4', and the attachment part 7 will be attached and fixed to the back of the bottom 1, and the attachment part 7 will be fixed at the crease line. By belt-folding through 9, the desired planar folded paper box can be obtained.
