[Problems to be solved by the device]

 Since the above-mentioned conventional technique is to hold the edge of the key piece against the edge of the notch provided in the corner of the lid against the rigidity of the key by the thickness of the material. If there is no room for the above-mentioned butting and locking dimensions, and the thickness of the material is not as thick as a thick cardboard, the butting and locking state of the thick edges will easily come off and the lid will stand upright. There is a problem that the shape of the body collapses and it becomes unusable.

For this reason, there is a problem that if the material is made thicker, a heavy and expensive material is required and it is uneconomical.

In order to eliminate the above-mentioned problems, the present invention devises the locking means of the corner portion of the folding box type cover to make the corner portion locked even if it is made of a relatively thin material. The purpose is to keep it fixed.

[0006]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to connect two pairs of side plates to each other on each of the four sides of a rectangular upper plate through folds, and to incline between adjacent side plates of each of these side plates through folds. Adhesive pieces and folding pieces having fold lines as boundaries are provided in series, and folding pieces are separately provided in series on the outer sides of the two pairs of side plates through creases. The locking piece and the tongue forming the above are connected to each other through the folds to form the cover lid expanding structure, and the plate pieces are all folded back inward by the folds, and the adhesive pieces are attached to the side plates. The inner surface of the folded piece is individually bonded to the surface of the bonded piece and the inner surface of the side plate, and each of the plate pieces is erected at a fold and the locking piece is attached. A hollow rectangular parallelepiped cover is formed by covering the upper edge of the folding piece, Folded inwardly pieces at the fold can be achieved by engaging locking the edge of the locking piece at the edge of this fold.

[0007]

[Action]

 Two pairs of side plates connected to each other on each of the four sides of the rectangular upper plate through folds, and an adhesive piece with a boundary between the inclined fold lines connected to each other between the adjacent side plates via folds. The folding piece and the folding piece are all folded back inward, and the adhesive piece is adhered to the inner surface of the side plate, and each inner surface of the folding piece is individually bonded to the surface of the adhered adhesive piece and the inner surface of the side plate. A hollow rectangular parallelepiped cover can be formed by bonding the plate pieces to each other so that each plate piece stands up at a fold and covering the upper edge of the folded piece with the locking piece.

[0008] The cover lid can have a three-dimensional shape by engaging and locking the edges of the locking pieces with the folding edges of the tongue pieces that are folded back inward. In particular, the folding edges float from the inner surface of the side plate due to the material rigidity. Since it is raised, the above locking can be reliably performed.

Further, by spreading the upper plate and the side plate outward by the folds and inclined fold lines between them, folding pieces and other side plates can be overlapped on the upper plate and the side plate, and the cover lid can be folded. Can be folded.
