Description

  The present invention relates to a cardboard packaging box that is opened along with the cutting of a cut line placed in a peripheral wall and removes a portion above the cut line.

  As a packaging box that can also be used for packaging and display of products, the following Patent Document 1 describes a packaging box as shown in FIG. The packaging box is connected in series so that the end plate 51 and the side plate 52 form a peripheral wall, and the inner and outer flaps 53 and 54 extending from the upper and lower sides of the end plate 51 and the side plate 52 are folded and sealed. Corrugated cardboard box.

  In this packaging box, one end plate 51 is provided with a tear band 55a sandwiched between two cut lines 55 that traverse an intermediate lower portion in the height direction. The cut line 55 is a zipper type in which a saddle-shaped cut is intermittently formed, and a cut-off portion 55b is provided at the center of the tear strip 55a with a horizontal H-shaped cut.

  Further, the tear strips 56a sandwiched between two cut lines 56 following the cut lines 55 are provided on both side plates 52 obliquely upward, and the tear bands 56a are separated from the boundary with the outer flap 54 on the top surface. It reaches to the middle part. The cut line 56 is a zipper type in which hook-shaped cuts are intermittent.

  In addition, a cut line 57 following the cut line 56 is provided at the boundary between the side plate 52 and the outer flap 54 up to the upper end of the other end plate 1, and the full width is provided at the boundary between the end plate 51 and the inner flap 53 on the top surface. A cut line 58 is formed over the entire area. In the cut lines 57 and 58, diagonal cuts straddling the ruled lines at the ridges are intermittent.

  When opening the packaging box, the tear line 55a is pulled from the cut start portion 55b to cut the cut line 55, and then the tear line 56a is pulled to cut the cut line 56, and the tear marks 55a, 56a are cut off.

JP 2011-255897 A

  However, in the packaging box as described above, since the opening cut line 55 crosses the one end plate 51 over the entire width, the compressive strength is remarkably lowered, and a large loading load or impact load is generated during distribution. When acting, there is a possibility that deformation such as buckling may occur.

  Further, when opening, the tear lines 55a and 56a are pulled to cut the cut lines 55 and 56, and further, the cut lines 57 and 58 must be cut, which is troublesome and is cut like the tear bands 55a and 56a. There was a problem that the fragments were generated as garbage and the disposal became troublesome.

  Therefore, the present invention provides a packaging box that can ensure the compressive strength in the packaged state without damaging the visibility of the product as the contents in the opened state, is easy to open, and is easy to dispose of. Let it be an issue.

  In order to solve the above-mentioned problems, the present invention includes a peripheral wall and a bottom wall in which end plates and side plates are connected in series, and bends and seals an inner flap extending from the upper side of the end plate and an outer flap extending from the upper side of the side plate. When opening, an inner flap connected to the upper side of the end plate in a packaging box that cuts a circumferential cut line across the end plate and removes the upper lid portion from the lower tray portion. In this case, a receiving piece is formed by making a score line from the boundary with the end plate, and when packaging, the inner flap is overlapped on the inner surface of the end plate while leaving the receiving piece so as to cover the score line and reach the bottom. The outer flap was received by the receiving piece.

  In addition, the side portion of the inner flap that is folded over the inner surface of the end plate is provided with a folding column portion with the root separated from the end plate on the outer side of the side folding line extending from the root toward the tip. The folding column portion is bent obliquely inward, and the outer flap is added to the receiving piece to be received at the upper end of the folding column portion.

  The pair of end plates and side plates are crossed at an intermediate portion in the height direction, and a score line is formed, and each pair of end plates and side plates is provided with a finger insertion portion facing the intermediate portion of the score line. The auxiliary ruled line is inserted from the vicinity of the finger insertion part so as to spread in a V shape upward, and when opening, when the part facing the finger insertion part is pulled, the end plate and the side plate are bent so as to protrude along the auxiliary ruled line. The cut line is to be cut.

  In the packaging box according to the present invention, in the packaged state, the inner flap overlaps the inner surface of the end plate where the crossing cut line is put, so that the end plate is reinforced and buckling along the cut line is less likely to occur. Further, since the outer flap of the top surface received by the receiving piece is prevented from falling, the compressive strength is ensured, and deformation due to the loading load during distribution is prevented.

  Also, when opening, the reinforcing inner flap is separated from the tray part as a part of the lid part, so that it can be easily opened, and a cut piece separated from the tray part and the lid part does not occur with cutting, There is no hassle for disposal.

The flap 6 is pulled up and the cut line 11b is cut. At this time, since the inner flap 4 bends so as to rise along the auxiliary ruled line 13b, a large tensile force acts on the connecting portion of the score line 11b, and the score line 11b can be easily cut.

  Subsequently, when the inner flap 4 and the outer flap 6 are further pulled up, the cut lines 12c, 12b, and 12a are cut, and then the lid part 22 is twisted, so that the cut line 11a is cut and the tray part 21 and the lid part are cut. 22 so that the lid portion 22 is removed from the tray portion 21, and as shown in FIG. 4, the product G accommodated in the tray portion 21 is exposed so that the product located on the front side can be seen to a low position. Can be exhibited.

  In the packaging box as described above, in the packaged state, the inner flap 4 overlaps the inner surface of the one end plate 1 in which the crossing cut line 11a is put, so that the end plate 1 is reinforced and along the cut line 11a. In addition to being less likely to buckle, the outer flap 6 on the top surface is received by the receiving piece 14 rising from one inner flap 4 and the other inner flap 4, and the outer flap 6 is prevented from falling, so compression Strength is ensured, and deformation due to the loading load during distribution is prevented.

  Further, since the reinforcing inner flap 4 is separated from the tray portion 21 as a part of the lid portion 22 at the time of opening, it can be easily opened, and a cut piece separated from the tray portion 21 and the lid portion 22 along with the cutting is provided. It does n’t happen and there ’s no need to dispose of it.

  Next, 2nd Embodiment of the packaging box based on this invention is described based on FIG.5 and FIG.6. Here, the description of the same parts as those in the above embodiment is omitted, and the feature points will be described.

  This packaging box is formed from a blank as shown in FIG. In this blank, side folding lines 4a extending from the root toward the tip direction are put on both sides of the short inner flap 4 connected to the upper side of the end plate 1 in which the score line 11a is put, and the root is the end plate 1 on the outer side. Folding column part 15 separated from is provided.

  The inner flap 4 is wider than the end plate 1 and protrudes on both sides by inserting only a score line between the inner flap 4 and the adjacent outer flap 6 instead of a groove having a width. The side fold line 4a is a lead ruled in which the cut and cuts are alternately interrupted in order to enable valley folding where the surface side is depressed. Further, an extension portion 3 a that is attached to the inner surface of the bottom inner flap 5 is provided at the lower end of the passage piece 3.

  When assembling such a blank and packaging a product, as shown in FIG. 6, the folding column 15 is bent diagonally inward, and the outer flap 6 is added to the receiving piece 14 at the upper end of the folding column 15.
