DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box body (i.e., a lower box) that can be folded and transported and stored in a flat shape, and can be assembled as a whole by a simple operation. The present invention relates to a paper raising box that can be applied to an upper box (lid box) to be placed on a paper box.

[0002]

2. Description of the Related Art Conventionally, a confectionery box has a three-dimensional structure comprising a box body and an upper box to be put on the candy box, and has a problem that it is bulky in storage and transport. In view of this, the present applicant has previously described in Japanese Utility Model Application Laid-Open No. 64-35820 a method in which a bendable side wall comprising an inner wall portion and an outer wall portion is provided around the bottom of a rectangular box, and adjacent outer wall portions can be bent. We proposed a paper box which was connected by a simple side plate connecting piece, and further provided a triangular bent part on both sides of the opposing inner wall part and joined the inside to the outer wall part. By using the paper raising box, the paper raising box can be folded and stored and transported in a flat shape, and when further used, the surrounding inner wall and outer wall can be raised by a simple operation. , Could be used as a box.

[0003]

However, in the paper-raising box described in the above publication, at the final assembly stage, the side plate connecting pieces are sandwiched between the opposing inner and outer wall portions to form the inner wall portion. Since the pressure-sensitive adhesive was used to fix the triangular bent parts on both sides of the, there is no problem while the pressure-sensitive adhesive is new, but when the old ones, the adhesive does not work and it can not be assembled There was a problem that there is.

Here, it is conceivable to use a double-sided tape. However, since the bent portion to be joined is on the back side, it is troublesome to peel off the protective tape at the time of assembling. There was a problem that the assembled paper box was distorted.

Further, in the paper raising box described in the above-mentioned publication, there is only one connecting bending line between the outer wall portion connected to the periphery of the box bottom and the inner wall portion connected to the outside thereof. Therefore, it is good when the paper to be used is thin, but it is difficult to bend when it is slightly thick, and furthermore, when assembling without using an adhesive, it is necessary to finally hook the bent part of the inner wall part, Since there is no gap between the outer wall and the inner wall, there is a problem that the treatment is troublesome. The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a paper box that can be formed flat when transported or stored and that can be assembled without using an adhesive or the like as a main component during use. And
