Description

  The present invention relates to a packaging box provided with a fine print display section such as a barcode.

  2. Description of the Related Art Conventionally, a packaging box for packaging a product and displaying it at a store has a barcode printed thereon, and information on the product is recorded on the barcode to facilitate management of the product. In recent years, an RSS code is used as a kind of barcode, and the RSS code is provided with a fine design. As a method of forming the RSS code, by printing black ink on the surface of the packaging box and irradiating a laser beam with a laser device to form a white portion where the ink is partially removed by heat, the RSS code or the like is formed. Bar codes can be formed. It is also possible to form a barcode with a high-precision inkjet printer. However, if friction is applied to the display part such as a barcode during transportation, etc., the ink part may be rubbed and the ink may adhere to the white part, or the ink in the printed part may peel off and become dirty. Also, there is a risk that the display of the RSS code or the like becomes unclear.

Here, as a method for protecting the printing of the packaging box from friction, there are methods disclosed in Patent Documents 1 to 4. The corrugated cardboard and the corrugated cardboard die of Patent Document 1 are corrugated cardboard boxes on which barcodes are printed. A concave portion is formed and information is displayed on the bottom surface of the concave portion. In the packaging box of Patent Document 2, a recess is provided in a part of the exterior surface of the packaging box, and a product code is attached to the recess. In the packaging box of Patent Document 3, the printed display portion is exposed at a position recessed from the surface of the packaging box body. The plastic shipping box of Patent Document 4 is formed by forming a shallow concave portion having the same shape as a thin piece to be attached to the peripheral surface of the plastic box, and attaching a thin piece with a barcode to the concave portion. In any of the methods, since the display unit is located on the concave surface, friction is not applied during transport or the like, and the display unit can be prevented from becoming unclear.

The side surfaces 14, 16, 18, and 20 are separated by crease lines 22, 24, and 26, respectively.

  On the side surface 14, a trapezoidal flap 34 is provided at one end in a direction perpendicular to the connecting direction between the side surfaces, separated by a crease line 36. A rectangular opening 38 is formed in a portion of the side surface 14 close to the crease line 36 and the crease line 22. A trapezoidal flap 40 is provided at the end of the side surface 14 opposite to the crease line 36 and separated by a crease line 42.

  A trapezoidal flap 44 is provided at the end of the side surface 18 that is located substantially on the extended line of the crease line 36 on the side surface 14, separated by the crease line 46. A trapezoidal flap 48 is provided at the end of the side surface 18 opposite to the crease line 46 and separated by the crease line 50.

  A cover piece 52 is provided on an end of the side surface 20 adjacent to the crease line 46 on the side surface 18, separated by a crease line 54. An insertion piece 56 is further provided at the end of the lid piece 52 opposite to the crease line 54 and separated by a crease line 58. At the end of the side surface 20 opposite to the crease line 54, a lid piece 60 is provided by being separated by a crease line 62. An insertion piece 64 is further provided on the end of the lid piece 60 opposite to the crease line 62 by being separated by a crease line 66.

  A display piece 68 that is glued to the back surface of the side surface 14 in an assembled state of the packaging box 10 is provided on the side edge of the side surface 20 opposite to the side surface 18, separated by a crease line 70. The size of the display piece 68 is slightly smaller than the side surface 14, and the side edge 68 a opposite to the crease line 70 is formed in a trapezoid shorter than the crease line 70. In the portion of the display piece 68 that is close to the crease line 70, a band-like paste portion 72 that is substantially parallel to the crease line 70 is provided. Between the glued portion 72 and the side edge portion 68a, a display portion 74 is provided at a position near the crease line 54 on the side surface 20, that is, near the upper side of the drawing. The display part 74 is formed by an ink part 74a to which black ink is applied and a white part 74b from which the ink is removed to expose the blank sheet 12, and an RSS code or the like is formed. The display unit 74 is provided in a portion of the side surface 14 that faces the opening 38 when the packaging box 10 is assembled, and is slightly larger than the opening 38.

  As shown in FIG. 4, the display part 74 is formed by applying black ink on the entire surface of the box-forming piece 12 to provide an ink part 74a, and a laser beam is emitted from a laser device 76 at a predetermined position of the ink part 74a. 78, and the ink is removed by heat to form a white portion 74b.

  Next, an example of an assembly method of the packaging box 10 of this embodiment will be described. Here, FIG. 3 shows the surface of the box-forming piece 12 of the packaging box 10, the folding method in which the surface of the box-forming piece 12 is convex and the folding in which the back surface is convex. This is called reverse folding.

  First, the crease line 26 is normally folded and glue is applied to the glue portion 72 of the display piece 68. Next, the crease line 22 is normally folded, and the back surface of the side surface 14 is glued to the surface of the display piece 68 by the glue portion 72. At this time, the display unit 74 of the display piece 68 is exposed to the opening 38 of the side surface 14. However, the thickness of the box-forming piece 12 is recessed in the display unit 74 rather than the surface of the side surface 14.

  Next, in a factory or the like where products are stored and packaged, the crease lines 22, 24, 26, and 70 are each normally folded at 90 degrees to form a rectangular box. Next, the flaps 34 and 44 are normally folded at 90 degrees with the crease lines 36 and 46, and then the lid piece 52 is normally folded at 90 degrees with the crease line 54, and the insertion piece 56 is normally folded with the crease line 58, The insertion piece 56 is inserted and locked on the back side of the side surface 16 to form one end surface. Further, the flaps 40, 48 are folded forward at 90 degrees with the crease lines 42, 50, the lid piece 60 is folded forward at 90 degrees with the crease lines 62, and the insertion piece 64 is folded forward with the crease lines 66, and inserted. The piece 64 is inserted and locked on the back side of the side surface 16 to form the other end face. The order of assembling the box forming pieces 12 may be other than this, and can be changed as appropriate.

  The packaging box 10 in which the product is put is transported and stored, for example, by packing the same packaging box 10 into a large box. And it is displayed in the store etc. Note that the display unit 74 may be formed using the laser device 76 after the product is stored.

  According to the packaging box 10 of this embodiment, the display unit 74 on which an RSS code or the like is formed can be protected from friction between boxes during transportation, storage, display, or the like. Since the display unit 74 is provided on the display piece 68 bonded to the back surface of the side surface 14 and appears to be exposed to the opening 38 of the side surface 14, the thickness of the side surface 14 is recessed from the surface of the side surface 14. When the part 74 is transported, stored, or displayed, it is safe because it does not come into contact with the adjacent packaging box 10 or packaging box. In addition, the friction of the ink portion 74a prevents the ink portion 74a from adhering around the white portion 74b and the display portion 74 and the ink portion 74a from peeling off, and keeps the packaging box 10 clean. In addition, the shape of the RSS code can be maintained, and information on products such as medicines and foods can be accurately read to manage the products. Since the packaging box 10 is provided with a single box-forming piece 12, it is not costly and the assembly process is simple.

  In addition, this invention is not limited to the said embodiment, A design other than RSS barcode may be sufficient as a display part. The blank sheet of the box forming piece may be a resin sheet or the like other than paper. In addition, the shape of the box can be appropriately changed according to the product to be accommodated, and the positions and number of the openings and the display portions can be freely changed. For example, a display part may be provided in a flap and an insertion piece, and an opening part is provided in the lid piece and side surface on which a flap and an insertion piece are piled up in this case. Further, the barcode may be formed by a high precision ink jet printer.

It is a perspective view of the packaging box of one Embodiment of this invention. It is a cross-sectional view of the packaging box of this embodiment. It is an expanded view of the packaging box of this embodiment. It is the schematic which shows the formation method of the display part of the packaging box of this embodiment.
