  However, in the packaging boxes disclosed in Patent Document 1 and Patent Document 2, in order to insert the corner of the outer flap into the notch of the inner flap, it is necessary to bend the corner of the outer flap at one end. The strength may decrease at the part where it is.

  In view of the above circumstances, an object of the present invention is to provide a packaging material that can lock an outer flap to an inner flap with a single touch and can be bundled according to the shape of an object to be packed.

  In order to achieve the above object, a packing material according to the present invention includes a rectangular tubular body, a pair of inner flaps that are connected to one opposing edge of the opening of the body and bent inward, and the opening. A pair of outer flaps connected to the other opposing end edges of the pair of inner flaps and stacked on the outer sides of the pair of inner flaps, wherein the pair of inner flaps includes the pair of outer flaps. A notch piece is formed by a notch line into which a corner of the outer flap can be inserted and an auxiliary notch line extending from both ends of the notch line, and the inside corner of the outer flap is overlapped with the notch piece of the inner flap. The corners are inserted into the score lines by pressing to the cut line.

  By adopting such a configuration, the corner can be inserted into the cut piece and locked only by pressing the corner of the folded outer flap, so that the packaging work of the packing material can be simplified.

  In the packing material of the present invention, the cut piece may have a trapezoidal shape surrounded by the straight cut line and the C-shaped auxiliary cut line.

  By adopting such a configuration, the cut piece can be formed in a shape along the corner of the outer flap, so that the cut piece can be easily pressed together with the corner. Further, since the corner of the inserted lid flap is sandwiched between the inner flap and the cut piece, the corner of the outer flap can be reliably locked to the inner flap.

  In the packing material of the present invention, the corner of the outer flap may be formed in an arc shape.

  By adopting such a configuration, the corner can slide smoothly along the cut line, and the corner can be inserted into the cut line with a light force.

  In the packing material of the present invention, a pair of inner bottom flaps connected to one opposing end edge of the lower opening of the body portion and bent inward, and connected to the other opposing end edge of the lower opening. A pair of outer bottom flaps that are folded inward to overlap the lower sides of the pair of inner bottom flaps and close the lower opening, and one outer bottom of the pair of outer bottom flaps The flap may have a longer length than the other outer bottom flap and an opening is formed, and the pair of inner bottom flaps may be formed so as not to overlap the opening.

  By adopting such a configuration, it is only necessary to form an opening provided in order to escape the projection of the article to be packed in only one outer bottom flap, so that the packaging material can be easily manufactured and assembled.

  In the packing material of the present invention, one inner bottom flap of the pair of inner bottom flaps may be configured to be capable of forming a stepped bottom raising portion by being bent.

  By adopting such a configuration, there is no need to use a separate member when the contents are raised and placed inside the packaging material, and the bottom raising portion is assembled as one of the packaging material assembly steps. Therefore, the cost can be reduced and the assembling work can be simplified.

  According to the present invention, since the outer flap can be locked to the inner flap with one touch, the packing operation can be made efficient.

By connecting by 10c, the square cylinder-shaped trunk | drum 10 is formed.

  The pair of outer lid flaps 11 and 12 can be bent at the upper edge of each of the pair of long side plates 10b of the trunk portion 10 from the inner side of the bending lines on both sides of the long side plate 10b via the fold lines 19 and 20. It is connected. The corners of the leading edge and both side edges of each of the outer lid flaps 11 and 12 are formed in an arc shape. The length L1 of the pair of outer lid flaps 11 and 12 is the same, and the sum of the length L1 of the pair of outer lid flaps 11 and 12 is formed shorter than the width W1 of the short side plate 10a of the trunk portion 10. . That is, when the pair of outer lid flaps 11 and 12 are bent inward, a predetermined gap is formed between the leading edges of the outer lid flaps 11 and 12.

  The pair of inner lid flaps 13, 14 are connected to the upper edges of the pair of short side plates 10 a of the trunk portion 10 via folding lines 21, 22 so as to be foldable. The length L1 of the pair of inner lid flaps 13 and 14 is the same as the length L1 of the pair of outer lid flaps 11 and 12, and the sum of the length L1 of the pair of inner lid flaps 13 and 14 is the trunk portion 10. The long side plate 10b is shorter than the width W2. That is, when the pair of inner lid flaps 13 and 14 are bent inward, a predetermined gap is formed between the leading edges of the inner lid flaps 13 and 14.

  As shown in FIGS. 4 (A) and 4 (B), the inner lid flaps 13 and 14 are formed with cut lines 25 into which the corners of the outer lid flaps 11 and 12 are inserted. Each cut line 25 is formed with an auxiliary cut line 26 extending in a C shape from both ends toward the leading edge and the side edge of each inner lid flap 13, 14. The inclination angle of the cut line 25 with respect to the folding lines 21 and 22 is 45 °. An auxiliary cut line 26 extending from one end of the cut line 25 toward the leading edge of the inner lid flaps 13, 14 is formed in parallel to the side edge of the inner lid flaps 13, 14, and from the other end of the cut line 25 to the inner lid flap. The auxiliary cut lines 26 extending toward the side edges of the 13 and 14 are formed in parallel to the front end edges of the inner lid flaps 13 and 14. A semicircular cutout 27 is formed in the center of the cut line 25.

  A trapezoidal cut piece 28 is formed in each of the inner lid flaps 13 and 14 by the cut line 25 and the auxiliary cut line 26. A ruled line 29 is formed between ends of the auxiliary cut line 26 opposite to the cut line 25, and the cut piece 28 can be bent around the ruled line 29.

  The pair of outer bottom flaps 15, 16 are connected to the lower edges of the pair of long side plates 10 b of the trunk portion 10 via folding lines 31, 32 so as to be bendable. The pair of outer bottom flaps 15 and 16 are formed such that the length of one outer bottom flap 15 is longer than the length of the other outer bottom flap 16. The length L2 of the longer outer bottom flap 15 is about twice the length L3 of the shorter outer bottom flap 16, and the sum L2 + L3 of the lengths of the pair of outer bottom flaps 15 and 16 is the trunk portion 10. The short side plate 10a is formed to be substantially the same as the width W1. The longer outer bottom flap 15 has a rectangular opening 35 that is long in the length direction on one side edge side. Between the front edge of the outer bottom flap 15 and the opening 35, the width of the adhesive tape for sealing between the front edges of the pair of outer bottom flaps 15, 16 (half the width of the adhesive tape) Is open.

  The pair of inner bottom flaps 17, 18 are connected to the lower edges of the pair of short side plates 10 a of the body portion 10 via fold lines 37, 38 so as to be bendable. The pair of inner bottom flaps 17 and 18 are formed such that the length of one inner bottom flap 18 is longer than the length of the other inner bottom flap 17. The length of the longer inner bottom flap 18 is equal to the length L2 of the longer outer bottom flap 15, and the length of the shorter inner bottom flap 17 is equal to the length L3 of the shorter outer bottom flap 16. equal.

  The long inner bottom flap 18 is formed with four fold lines 41 parallel to the fold lines 38, and is bent at each of the fold lines 41, so that the bottom-up portion 43 (see FIG. 2) is formed. The four folding lines 41 define the longer inner bottom flap 18 on the bottom surface 44, the side surface 45, the top surface 46, the side surface 47, and the overlapping portion 48 of the bottom raising portion 43 in order from the folding line 38. Yes. The bottom surface portion 44 is formed with a pair of insertion pieces 51 that can be bent via a folding line 38, and the side surface portion 47 far from the bottom surface portion 44 can be inserted into each insertion piece 51. 52 is formed. Each insertion piece 51 has an inverted trapezoidal shape, and the opening 52 is formed in a rectangular shape. A semicircular cutout 53 is formed in the upper surface portion 46 so as to be continuous with the opening 52.

  As shown in the developed view of FIG. 3, the pair of outer bottom flaps 15 and 16 and the pair of inner bottom flaps 17 and 18 are adjacent to each other with shorter flaps 16 and 17 and have a longer length. The respective flaps 15 and 18 are formed adjacent to each other.

  A method for assembling the packaging material 1 having the above configuration will be described with reference to FIGS. 5 to 7 are perspective views showing the assembly process. First, as shown in FIG. 5, the inner bottom flap 18 having a long length is bent into a rectangular tube shape at each folding line 41 in the lower opening of the trunk portion 10, and each insertion piece 51 is opened 52. The bottom raised portion 43 is formed. Then, the bottom raised portion 43 and the shorter inner bottom flap 17 are folded inward along the folding lines 38 and 37, and then the outer bottom flaps 15 and 16 are folded along the folding lines 31 and 32 to raise the bottom raised portion 43 and the inner bottom flap 17. On the outside. And the front-end | tip edge of each outer bottom flap 15 and 16 is faced | matched, and both front-end | tip edges are sealed with the adhesive tape T (refer FIG. 6). Here, in the longer outer bottom flap 15, the adhesive tape is affixed to the outer portion of the opening 35, so the adhesive tape does not overlap the opening 35. Since the lengths of the outer bottom flaps 15 and 16 are different, the abutted leading edge is displaced from the center of the trunk portion 10 in the short direction.

  By assembling the outer bottom flaps 15 and 16 and the inner bottom flaps 17 and 18 as described above, a rectangular opening 35 is formed on the bottom surface of the packing material 1 as shown in FIG. Inside the opening 35, a rectangular tube-shaped bottom raised portion 43 having a horizontally long cross-sectional shape is formed.

  Next, the packaged item is accommodated in the body part 10. At this time, since the bottom raised part 43 is formed inside the body part 10, the packaged object is lifted from the bottom by the height of the bottom raised part 43. Retained. Thereafter, the pair of inner lid flaps 13, 14 are folded inward along the folding lines 21, 22 in the opening on the upper side of the body 10. Here, a space is opened between the leading edges of the inner lid flaps 13 and 14. Then, when the outer lid flaps 11 and 12 are folded inward along the folding lines 19 and 20, the corners of the outer lid flaps 11 and 12 overlap with the cut pieces 28 of the inner lid flaps 13 and 14.

  When the corners of the outer lid flaps 11 and 12 are pressed downward, the cut pieces 28 are bent downward along the ruled lines 29 together with the corners of the outer lid flaps 11 and 12. When the corners of the outer lid flaps 11 and 12 reach the cut line 25, they enter the lower side of the inner lid flaps 13 and 14 while warping along the cut line 25 (see FIGS. 4A and 4B). . That is, as shown in FIG. 7, the corners of the outer lid flaps 11 and 12 are inserted into the cut line 25. Thereafter, when the pressing force of the outer lid flaps 11 and 12 is released, the cut piece 28 returns to its original shape and comes into contact with the lower surface of the corners of the outer lid flaps 11 and 12.

  The packaging material 1 assembled in this way is interposed between the upper surface of the article 2 and the upper surface of the packaging box 3 as shown in FIG. At this time, the handle 2 a formed on the upper surface of the article to be packed 2 is inserted into the opening 35 on the bottom surface of the packing material 1.

  As described above, in the packaging material 1 according to the present embodiment, the inner lid flaps 13 and 14 are locked by the one-touch operation of simply pushing the corners of the outer lid flaps 11 and 12 in the upper opening of the packaging material 1. Therefore, packing work can be performed efficiently. Furthermore, since the corners of the outer lid flaps 11 and 12 are formed in an arc shape, the corners can smoothly slide along the cut line 25, and the corners can be inserted with a light force.

  Further, the outer cover flap 11 is formed by forming the cut piece 28 into a trapezoidal shape surrounded by the cut line 25 and a C-shaped auxiliary cut line 26 extending from both ends of the cut line 25 toward the edges of the inner cover flaps 13 and 14. , The shape along the 12 corners makes it easier to press the cut pieces 28 and the corners. Further, after the corners of the outer lid flaps 11 and 12 are inserted into the cut lines 25, the cut pieces 28 hit the lower surfaces of the corners of the outer lid flaps 11 and 12, and the corners are held between the inner lid flaps 13 and 14 and the cut pieces 28. The Alternatively, an upward force is applied from the cut piece 28 to the corner. Therefore, the corners of the outer lid flaps 11 and 12 can be reliably locked to the inner lid flaps 13 and 14.

  Furthermore, the handle 2a can be protected by forming the opening 35 in the bottom and accommodating the handle 2a of the article 2 to be packed in the opening 35. Moreover, since the long opening 35 should just be formed only in one outer-bottom flap 15, manufacture and an assembly of the packing material 1 can be made easy. When such a long opening 35 is formed, it can be formed across a pair of outer bottom flaps 15 and 16, but in that case, it is necessary to form a rectangular cutout in the pair of outer bottom flaps 15 and 16. Because there is, the manufacturing process increases. Moreover, since it is necessary to divide | segment the adhesive tape which seals between the front-end | tip edges of the outer bottom flaps 15 and 16 by the opening 35, it will take an effort. In the present embodiment, one outer bottom flap 15 is formed long, and the opening 35 is formed only in this outer bottom flap 15, so that the packaging material 1 can be easily manufactured and sealed with a single adhesive tape. Can be stopped. It should be noted that the shape and position of the opening 35 can be appropriately adjusted according to the shape of the projection of the packaged object. For example, even when a protrusion is provided in the vicinity of the center of the article to be packed, an opening corresponding to the position and shape of the protrusion may be formed only in the longer outer bottom flap 15.

  Further, in the pair of inner bottom flaps 17 and 18, one inner bottom flap 17 is shorter than the other inner bottom flap 18 and is formed so as not to overlap the opening 35. Further, since the bottom raising portion 43 formed by bending the longer inner bottom flap 18 is located on the side of the opening 35, it does not overlap the opening 35.

  Furthermore, since the bottom raising part 43 is formed, a packaged item can be raised from the bottom surface of the packing material 1 and placed. In this embodiment, since the bottom raised portion 43 is formed on the side of the opening 35, the handle 2 a enters the space formed on the lower side of the package mounted on the bottom raised portion 43, and the handle 2 a Interference with the package can be avoided. Moreover, since the bottom raising part 43 can be assembled as one of the assembly processes of the packing material 1, compared with the case where another member is used, an assembly operation can be simplified and cost can be reduced.

  Further, as shown in the developed view of FIG. 3, the pair of outer bottom flaps 15 and 16 and the pair of inner bottom flaps 17 and 18 are adjacent to each other, and the lower flaps 16 and 17 are adjacent to each other. Since the higher flaps 15 and 18 are adjacent to each other, when the shape of the developed view is cut out from the blank of the packing material, the wasteful portion of the packing material can be reduced as much as possible.

  Furthermore, since the square opening is formed between the tip edges of the pair of inner lid flaps 13 and 14 and between the tip edges of the pair of outer lid flaps 11 and 12, the contents of the packaging material 1 can be easily confirmed.

  In addition, although the case where this embodiment was applied to the packing material 1 was demonstrated, applying this embodiment to the inner flap and outer flap which close the opening of a packing box in the packing box in which a to-be-packaged item is packed. You can also.

  Furthermore, since the above description of the embodiment of the present invention describes a preferred embodiment of the packaging material according to the present invention, there may be various technically preferable limitations. The technical scope of the invention is not limited to these embodiments unless specifically described to limit the present invention. That is, the above-described components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. The description of the embodiment of the present invention described above does not limit the contents of the invention described in the claims.
