Description

  The present invention relates to a handle hole structure in which a gripping hole is provided on a wall having a two-layer structure, and is particularly suitably applied to a packaging box that stores products such as beverages stored in bottles and cans.

  Conventionally, a wrap-a-land type packaging box includes a rectangular bottom wall, side walls provided on both side edges of the bottom wall, and a ceiling wall provided between upper ends of the side walls. And, the side wall is provided with inner flaps at both end edges, and at the both end edges of the bottom wall and the top wall are provided outer flaps that are superimposed on the outside of the inner flap, and thereby the end walls are formed by these. It is composed. In addition, there is a packaging box of this type in which a pulling part for a handle is provided on an opposing wall surface so that convenience during transportation can be improved.

  The packaging box according to the present invention is such that one wall is constituted by the flaps constituting the inner wall portion and the outer wall portion, and a handle punching portion is provided in that portion, and as related prior art document information Has the following:

JP-A-6-329146

  This Patent Document 1 describes a packaging box in which a top wall is configured by a flap and a handle extraction part is provided at that portion. Specifically, in this packaging box, a pair of inner flaps are formed to have a size that abuts each other in an assembled state, and a semi-long oval cutout is formed at each leading edge. In addition, the outer flap that is superimposed on the outer side is formed with a handle punching portion formed of an oblong hole so as to be located at the center. As a result, a handle hole is formed which leads to the inside through the outer flap extraction part and the inner flap notch part. In addition, since the entire outer peripheral edge has a two-layer structure, the grip hole can increase the rigidity in the gripped state.

  However, in the cited document 1, since it is necessary to form the pair of inner flaps with dimensions that the leading edges of the inner flaps meet, there is a problem that the use area of the base paper constituting the packaging box increases and the cost increases. .

  In addition, there is a packaging box in which each inner flap is formed with a dimension that forms a predetermined gap between its front end edges, and a handle hole is provided at a position overlapping only one inner flap of the outer flap. In this case, the position of the handle hole is shifted to a position away from the center, and there is a case where force is concentrated and gripped on the portion of the one-layer structure.

  The present invention has been made in view of the conventional problems, and the handle hole structure having a strong rigidity in the gripped state and the handle structure are used for the wall forming the two-layer structure without increasing the use area of the base paper. It is an object to provide a packaging box.

  In order to solve the above-mentioned problem, the handle hole structure of the present invention is a handle hole structure in which a hole for gripping is provided on a wall of a two-layer structure having a pair of inner wall portions and an outer wall portion overlapping the outside of the inner wall portions. In addition, the outer wall portion is provided with a handle extraction portion having an edge located in a region where one end in the lateral direction is positioned between the inner wall portions and the other end is overlapped with one inner wall portion, and the inner wall portion, A notch portion having an edge substantially coinciding with the edge of the handle extraction portion is provided, thereby forming a handle hole penetrating through the inside, and the edge of the handle extraction portion is bounded by the leading edge of the inner wall portion The non-overlapping region has a sloping edge extending inclining with respect to the leading edge of the outer wall portion, and a lateral edge extending along the leading edge of the outer wall portion in the overlapping region with the inner wall portion. The shape has.

  The packaging box using the handle hole structure includes a bottom wall, a pair of side walls located on both sides of the bottom wall, and a top wall located at the upper end of the side walls, and each side wall has an inner flap. In the packaging box which forms the end wall with these flaps, the outer flaps that overlap the outside of the inner flap and are opposed to each other on the top wall and the bottom wall, respectively. At least one is provided with a handle extraction portion having an edge located in a region where one end in the lateral direction is positioned between the inner flaps and the other end is overlapped with the one inner flap, and the handle extraction is provided on the inner flap. A notch portion having an edge substantially coincident with the edge of the portion is provided, and the edge of the pulling portion for the handle is inclined with respect to the leading edge of the outer flap in a non-overlapping region with the leading edge of the inner flap as a boundary. Tilt And having an edge portion, the overlapping region of said flap is obtained by a shape having a transverse direction extending edge along the leading edge of the outer flap.

  When transporting a packaging box using this handle hole structure, a hand is inserted into a handle hole made up of a handle extraction part and a notch part. If it does so, it will act so that a load may be applied to the deep part of a handle hole in the inserted hand, ie, the finger located in the horizontal edge of a superposition field by the weight of an internal goods. And since this horizontal edge part is provided in the overlapping area | region with an inner flap, the grip hole with the rigidity in the holding state made into the 2 layer structure only in the part where gripping force concentrates can be formed. Moreover, since it is not necessary to form an inner flap with the dimension in which a front-end edge mutually collides, the usage area of a blank can be reduced and cost reduction can be aimed at.

  In this packaging box, it is preferable to provide the pull-out part for the handle so as to be positioned substantially diagonally. In this way, the position of the hand is the same regardless of which side wall is held on the near side, so that the workability at the time of the conveyance work can be improved.

  In the handle hole structure of the present invention and the packaging box using the structure, since the inner flaps are not formed with a size that faces each other, the use area of the base paper can be reduced and the cost can be reduced. Further, in the gripping state, the portion where the force concentrates has a two-layer structure, so that it is possible to form a handle hole with high rigidity.

The fourth breaking ruled lines 24, 24 are provided. These breaking ruled lines 22, 23, and 24 include a cutting line provided at a predetermined interval so as to form a perforation, and a guide cutting line extending inwardly from one end of the cutting line. The side wall 11A is provided with a pair of cutout portions 25 and 25 for hooking fingers when the side wall 11A or the top wall 12 is broken.

  In the present embodiment, a grip hole 26 penetrating from the outside into the internal space is provided in the end wall constituted by the flaps 17A, 17B to 20A, 20B as gripping means when transporting the assembled packaging box. ing. The handle hole 26 includes a handle extraction portion 27 provided in the second outer flaps 20A and 20B connected to the top wall 12 located on the upper side in the assembled state, and one first inner flap 17A provided continuously to the side wall 11A. And a notch 29 provided in one second inner flap 18B provided continuously to the side wall 11B.

  The pull-out part 27 for the handle is constituted by a notch provided at a position biased to the right in front view of each of the second outer flaps 20A and 20B so as to be positioned substantially diagonally in the assembled packaging box. As shown in FIGS. 8A and 8C, the pulling portion 27 for the handle has a cutting edge 28 punched out by a cutting blade (not shown). The cutting edge 28 is laterally arranged so that one end thereof is located between the inner flaps 17A, 18A and 17B, 18B in an assembled state, and is located in a region overlapping with the inner flaps 17A, 18B forming a notch 29 described later. It extends to. When the cutting edge 28 is partitioned into a non-overlapping area A and a superimposing area B with the leading edge of the inner flaps 17A and 18B as a boundary, the non-overlapping area A is located at the leading edge of the second outer flaps 20A and 20B. It has a shape having an inclined edge portion 28a extending inclinedly so as to approach and a short orthogonal edge portion 28b extending from the front end of the second outer flap 20A, 20B in a direction orthogonal to the front end edge. In addition, the overlapping region B includes a lateral edge portion 28c extending in parallel along the tip edges of the second outer flaps 20A and 20B, and a long orthogonal shape extending in a direction orthogonal to the tip edges of the second outer flaps 20A and 20B. It has a shape having an edge portion 28d and a curved edge portion 28e that is continuous with the edge portion 28d. Thereby, in the non-overlapping region A, the width of the pull-out portion 27 in the handle is gradually narrowed by the inclined edge portion 28a, while in the overlapping region B, there is almost no change in the vertical width by the lateral edge portion 28c. It is configured as follows.

  As shown in FIGS. 8B and 8C, the notch 29 is formed by punching with a cutting blade (not shown) so as to coincide with the inside of the handle punch 27 in the assembled state. The cut edge 30 of the notch 29 includes a short first orthogonal edge 30a orthogonal to the front end edge of the inner flaps 17A and 18B, a long second orthogonal edge 30b, and a curved edge 30c continuous with these. And have. The first orthogonal edge 30a substantially coincides with the lateral edge 28c in the assembled state, and the second orthogonal edge 30b substantially coincides with the leading edges of the second outer flaps 20A and 20B. The curved edge portion 30c is configured to substantially coincide with the curved edge portion 28e.

  The packaging box having the above configuration is shipped to a predetermined manufacturer in a blank state shown in FIG. 7, for example, and sealed by an automatic assembly packaging device. Specifically, products are placed in a predetermined arrangement on the bottom wall 10 in a blank state. Thereafter, as shown in FIG. 1, the side walls 11A and 11B, the top wall 12 and the sticking portion 14 are bent around the bottom wall 10, and the sticking portion 14 is made of a hot-melt resin on the outer surface of the side wall 11A. It is stuck with an adhesive (hot melt). Next, as shown in FIG. 2, after the inner flaps 17A, 17B, 18A, 18B are bent, the outer flaps 19A, 19B, 20A, 20B are bent as shown in FIG. Is stuck with hot melt to form a sealed packaging box. Of course, the part of the handle extraction part 27 and the notch part 29 provided in the overlapping region B cannot be adhered with an adhesive.

  When transporting the sealed packaging box, a hand is inserted into the handle hole 26 including the handle extraction part 27 and the notch part 29 located diagonally. Then, due to the weight of the product inside, in the inserted hand, the deep part of the handle hole 26, that is, the overlapping edge B overlapped with the inner flaps 17A and 18B, the lateral edge 28c and the first orthogonal edge 30a. It acts so that a load is applied to the finger located.

  That is, in the non-overlapping region A, since the inclined edge portion 28a of the pull-out portion 27 for the handle is inclined with respect to the tip edge of the second outer flaps 20A and 20B, the finger of the hand can be inserted. The gripping force against the downward gravity is dispersed, and it becomes difficult to apply it vertically upward. On the other hand, since the extending direction of the lateral edge portion 28c extending along the leading edge of the second outer flaps 20A, 20B is substantially horizontal, it is possible to apply a gripping force vertically upward against the gravity of vertically downward. it can.

  Since the lateral edge portion 28c is provided in the overlapping region B with the inner flaps 17A and 18B, only the portion where the gripping force is concentrated forms a grip hole 26 having a strong rigidity in the gripping state. can do. Further, in this packaging box, the inner flaps 17A, 18A, 17B, and 18B are not formed so as to face each other, so that the use area of the base paper can be reduced and the cost can be reduced. Further, the handle hole 26 formed of the handle extraction part 27 and the notch part 29 is provided so as to be positioned substantially diagonally to the packaging box. Therefore, even if any of the side walls 11A and 11B is gripped on the front side, The positions of the hands are the same, and the workability during the transfer work can be improved.

  In addition, when taking out the goods in the said packaging box, for example, one end of the sticking part 14 shown in FIG. 3 is grasped, and the top wall 12 is formed along the first breaking ruled line 15 with the notch part 16 as a starting point. On the other hand, the sticking portion 14 is broken and separated as shown in FIG. Next, the side wall 11A is broken along the second breaking ruled lines 22 and 22 as shown in FIG. 5 by hooking a finger on the edge of the notch 25 at the upper end of the exposed side wall 11A and pulling it down. To expose. Thereafter, the top edge 12 is broken along the third breaking ruled lines 23 and 23 as shown in FIG. 6 by gripping the pulling edge by the first breaking ruled line 15 and pulling it upward. The side wall 11B is broken along the breaking ruled lines 24, 24. Thereby, an internal product can be easily taken out from the upper side which is largely developed.

  In addition, the packaging box of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the pull-out portion 27 for the handle extends the inclined edge portion 28a toward the non-overlapping region A with the leading edge of the inner flaps 17A and 18B as a boundary, and the lateral edge portion 28c toward the overlapping region B. 9A. However, as shown in FIG. 9A, the shape may extend from a position having a predetermined interval from the tip edge of the inner flaps 17A and 18B into the non-overlapping region A. As shown to (B), it is good also as a shape extended from the superimposition area | region B. FIG.

  Needless to say, the pull-out part 27 for the handle is not limited to the notch provided at the front end edge of the second outer flaps 20A and 20B, and may have an annular shape as shown in FIG. In this case, the one end and the other end of the handle extraction portion 27 mean the left and right top portions. In this configuration, in the non-overlapping region A, the vertical width is gradually narrowed by the inclined edge portion 28a, while in the overlapping region B, the vertical width is changed by the lateral edge portion 28c that is gently curved from the inclined edge portion 28a. And the same operations and effects as described above can be obtained.

  Furthermore, in the above-described embodiment, the handle extraction part 27 is provided on one of the outer flaps 19A, 20A and 19B, 20B constituting the end wall, but may be provided on both, and without being positioned diagonally, You may provide in the side biased to one side wall 11A, 11B.

  Furthermore, in the said embodiment, although applied to the packaging box which external appearance consists of a hexahedron, it is applicable similarly to the packaging box etc. which provided the chamfered wall in the predetermined ridge part. Of course, the present invention is not limited to the wrap-aland type packaging box, and can be applied to various types of boxes.

  For example, as shown in FIG. 10, a bottom wall 10, a pair of side walls 11A and 11B located on both sides of the bottom wall 10, end walls 40A and 40B located at both ends of the bottom wall 10, and side walls 11A, In a packaging box provided with adhesive margin portions 41A and 41B attached to end walls 40A and 40B on 11B, a gripping portion 27 is provided on end walls 40A and 40B constituting the outer wall portion, and glue constituting the inner wall portion A handle hole 26 similar to that of the above-described embodiment may be configured by providing the notch portions 29 in the proxy portions 41A and 41B. Further, in this modification, the lid 42 provided continuously with the one side wall 11A is provided continuously, but a tray not provided with this lid 42 may be used.
