Description

  The present invention relates to a prefabricated cardboard packaging box.

  The inventor previously devised an assembly-type cardboard packaging box shown in FIGS. (Patent Document 1)

  The assembly type corrugated cardboard packaging box 100 includes a pair of rectangular corrugated paperboards 101, 102 each having a short side 101a, 102a parallel to the step of the cores 101A, 102A. A set of corrugated paperboards 101 and 102 are superposed and connected with a connecting shaft 103 at the center position in the length direction and the width direction, and the connecting shaft 103 can be rotated as a rotation fulcrum to be in an orthogonal state. It has been done.

  Further, the width of the corrugated paperboard 102 on one side is made slightly larger than the width of the corrugated paperboard 101 on the other side, and both ends are left at the required length L at the edge on the long side of the corrugated paperboard 102 on the one side. Protruding pieces 104 and 104 having a required width are integrally formed, and further, cuts 105 and 105 are formed in the central portions of the protruding pieces 104 and 104, and the cut and raised pieces are slightly narrower than the width of the corrugated paperboard 101 on the other side. 106 and 106 are provided, and fold lines 107 and 107 are attached to the bases of the cut and raised pieces 106 and 106, respectively.

  In addition, as described above, a pair of corrugated paperboards 101 and 102 are rotated with the connecting shaft 103 as a rotation fulcrum to be orthogonal to each other, so that the connecting shaft formed by cutting the corrugated paperboard into a circular shape. 103 is slidably fitted into a circular cutout 108 provided on the corrugated paperboard 101, and a cardboard 109 having a diameter larger than that of the circular cutout 108 is adhered to the upper end of the connecting shaft 103, and the cardboard 109 is brought into sliding contact with the upper surface of the corrugated paperboard 101, while the lower end portion of the connecting shaft 103 is adhered to the upper surface of the corrugated paperboard 102 with an adhesive 110. In addition, reference numeral 111 in the drawings is a viewing window that can be opened and closed by cutting it into an oval shape while leaving a part.

  When the assembled cardboard packaging box 100 is used, first, the corrugated paperboards 101 and 102 are arranged in the same direction as shown in FIG. It is rotated as a rotation fulcrum and brought into an orthogonal state. Then, as shown in FIG. 10, both side portions of the corrugated cardboard 101 are sequentially bent inward at a position suitable for the size of an item to be packaged (not shown). Thereafter, both side portions of the corrugated paperboard 102 are sequentially folded inward at a position suitable for the size of the package. Finally, the cut and raised pieces 106 and 106 are raised and placed on the outside of the side wall of the corrugated paperboard 101 and fixed with a packing tape (not shown) or the like.

  The assembly type corrugated cardboard packaging box 100 has the above-described configuration. If the two corrugated paperboards 101 and 102 that are superposed are changed to be orthogonal to each other, the short side of each corrugated paperboard 101 and 102 is a corrugated cardboard. Since it is parallel to the strip, it can be easily folded at any position. Therefore, there is no need to make a broken line, and labor and time required for this can be saved. In addition, the cost can be reduced. In addition, by stacking the two corrugated paperboards 101 and 102 in the same direction, it takes up space during storage and is easy to hold during transportation. Furthermore, since it can be easily bent at any position, it can be used for any type of packaged object.

  Further, the width of the corrugated paperboard 102 on one side is made slightly larger than the width of the corrugated paperboard 101 on the other side, and both ends are left at the required length L at the edge on the long side of the corrugated paperboard 102 on the one side. Protruding pieces 104 and 104 having a required width are integrally formed, and further, cuts 105 and 105 are formed in the central portions of the protruding pieces 104 and 104, and the cut and raised pieces are slightly narrower than the width of the corrugated paperboard 101 on the other side. Since 106 and 106 are provided, the impact is mitigated by the protruding pieces 104 and 104, and the cut and raised pieces 106 and 106 are reinforced because they cover the outside of the side wall of the corrugated paperboard 101, so that they become strong. In addition, the cut-and-raised piece portions 106 and 106 are raised to form a dent, and the gap between the dent and the stepped portion of the corrugated paperboard 102 covering the upper surface of the inner corrugated paperboard 101 is displaced. It can also be prevented.

  The assembling-type cardboard packaging box 100 previously devised by the present inventor has an excellent practical effect as described above. However, two corrugated paperboards 101 and 102 having different shapes are separately provided. In addition, the two corrugated paperboards 101 and 102 must be connected and integrated with the connecting shaft 103, and it takes time to manufacture each member, and the two corrugated paperboards 101 and 102 are produced. Further, there is a problem in that the work of connecting the two with the connecting shaft 103 is necessary, and it takes too much labor, time and cost for the entire production.

An object of the present invention is to provide a prefabricated cardboard packaging box that can achieve the same effect as a box.

  Thus, the gist of the present invention is to cut a sheet of corrugated paperboard, and to form a rectangular box-shaped body with different widths, with each short side parallel to the core step on the left and right. The box-shaped body is formed slightly below the center of the long side on the side where they are in contact with each other, with the long side of the left-side wide box-shaped body as one oblique side and the right-side narrow side The portion from the long side of the box forming body to the center is the other hypotenuse, and the base is formed in an arc shape, and a cut is made in the bottom side of the box forming body on the narrow side on the right side. It is connected by an inverted triangular connecting piece portion having an apex angle of 45 degrees formed by forming a fold line on the oblique side, and further, the central portion of the long side opposite to the connecting piece portion of the box forming body on the left wide side The locking tongue is formed on the upper side of the box forming body on the right narrow side. The location, in prefabricated corrugated board packaging box formed by providing a locking notch hole plugging the locking tongue.

  Further, in the above-described configuration, a U-shaped cut may be provided at a substantially central portion in the length direction of the box forming body on the right narrow side to provide a cut and raised piece portion for fixing an object to be packaged. .

  Furthermore, in the above configuration, protruding pieces having a required width are formed on both left and right long sides of the left wide box forming body so as to sandwich the connecting piece portion and the locking tongue-like piece, respectively. It may be.

  The present invention is configured as described above, and the entire box forming body can be manufactured simply by punching and cutting a piece of corrugated paperboard, and rectangular box forming bodies having different widths formed on the left and right sides. Since these are connected together by connecting pieces that are integrally formed at the same time, two corrugated paperboards and connecting shafts are separately manufactured as in the packaging box previously devised by the inventor. And, the great effort, time and cost required for the entire production of connecting two corrugated paperboards with a connecting shaft can be greatly reduced. The same effect as the packaging box can be obtained.
