[0011] (Background to this disclosure) The packaging material described in Patent Document 1 has an opening lid connected to the opening side of a box body, and an insertion piece protruding from the opening lid. At the connection part between the opening lid and the insertion piece, a slit is opened on the insertion piece side. In addition, a locking piece having an insertion part is formed on the box body. When the opening lid is closed and the insertion piece protruding from the opening lid is inserted inside the box body, the opening lid is locked in the closed position by inserting the insertion part of the locking piece into the slit.

[0012] For example, in the packaging material described in Patent Document 1, the insertion portion is inserted into the slit portion while the insertion portion is aligned with the slit portion. The slit portion is a relatively small hole in the packaging material. When the insertion portion is inserted into the slit portion, the insertion portion is smaller than the slit portion when viewed in the direction in which the insertion portion is inserted into the slit portion.

[0013] However, in the packaging material described in Patent Document 1, the slit is opened on the insert side of the connecting portion between the opening / closing cover and the insert piece, making it difficult to align the insert part with the slit. Therefore, it is difficult to insert the insert part into the slit while aligning the insert part with the slit. In addition, it is troublesome for the user to move the insert part away from the slit before inserting the insert part into the slit.

[0014] Furthermore, in the packaging material described in Patent Document 1, the insertion portion is smaller than the slit portion, but since the slit portion is a relatively small hole in the packaging material, it is difficult to insert the insertion portion into the slit portion.

[0015] In order to solve the above problems, the present inventors have investigated a packaging material that allows the lid to be easily locked, and have arrived at the present disclosure.

[0016] Hereinafter, a first embodiment according to the present disclosure will be described with reference to the accompanying drawings. In each drawing, each element is shown exaggerated for ease of explanation.

[0017] (Embodiment 1) The packaging material of this embodiment can be assembled by folding a blank sheet.

[0018] Fig. 1 is a plan view of an example of a blank sheet 1A from which a packaging material according to the first embodiment can be assembled. Fig. 2 is a perspective view of an example of a packaging material 2A according to the first embodiment. In the figure, the X-axis direction and the Y-axis direction indicate the horizontal direction, and the Z-direction indicates the vertical direction. In the figure, the first direction Z1 and the second direction Z2 are parallel to the Z-axis direction. In the figure, the third direction X1 and the fourth direction X2 are parallel to the X-axis direction. In the figure, the fifth direction Y1 and the sixth direction Y2 are parallel to the Y-axis direction.

[0019] (Blank sheet) The blank sheet 1A shown in FIG. 1 can be folded to assemble the packaging material 2A shown in FIG. 2. The blank sheet 1A is folded along fold lines 71 or cuts 75 to assemble the packaging material 2A. The blank sheet 1A shown in FIG. 1 is illustrated so that the outside is visible. The fold lines 71 of the blank sheet 1A may be creases formed by pressing the surface of the blank sheet 1A into a line, or discontinuous cuts may be formed in the creases. For example, the blank sheet 1A may be made of cardboard.

[0020] (Packing materials) The packaging material 2A according to the first embodiment will be described.

[0021] Fig. 3 is a perspective view of an example of a packaging material 2A according to embodiment 1. Fig. 3 is a perspective view of an example of the packaging material 2A in a state in which a lid 6A is locked. Fig. 4 is a plan view of the example of the packaging material 2A shown in Fig. 3. Fig. 5 is an enlarged perspective cross-sectional view of the packaging material 2A shown in Fig. 3 taken along line AA.

[0022] 2 and 3, the packaging material 2A includes a main body 3, a lid 6A, a lock tab 7A, and an arm portion 8. The packaging material 2A has a space inside in which an object can be stored.

[0023] The main body 3 has a box shape. The outer shape of the main body 3 is a rectangular parallelepiped.

[0024] The lid 6A is provided on the main body 3 so as to be openable and closable. The lid 6A has a rectangular shape. The lid 6A has a first main surface 81 and a second main surface 82 opposite to the first main surface 81. The lid 6A is provided with a through hole 20A penetrating in a first direction Z1 from the first main surface 81 toward the second main surface 82. When the lid 6A is viewed in a direction from the second direction Z2 toward the first direction Z1, the first main surface 81 of the lid 6A can be seen. In other words, viewing the lid 6A in a direction from the second direction Z2 toward the first direction Z1 means viewing the lid 6A in a direction along a direction from the first main surface 81 toward the second main surface 82 of the lid 6A. Hereinafter, the "direction from the second direction Z2 toward the first direction Z1" will be described as the "direction toward the first direction Z1".

[0025] As shown in FIG. 4, when the lid 6A is closed relative to the main body 3, the through hole 20A of the lid 6A is provided at the end of the lid 6A located on the main body 3 side where the lock tab 7A is provided, as viewed in the first direction Z1 of the packaging material 2A. As viewed in the first direction Z1, the through hole 20A has a semicircular shape. As viewed in the first direction Z1, the maximum length L1 of the through hole 20A in the X direction is greater than the maximum length L2 of the through hole 20A in the Y direction. The length L1 of the through hole 20A is 1.2 times or more and 2.5 times or less than the length L2 of the through hole 20A. Preferably, the length L1 of the through hole 20A is 1.5 times or more and 2.2 times or less than the length L2 of the through hole 20A. More preferably, the length L1 of the through hole 20A is 1.8 times or more and 2.0 times or less than the length L2 of the through hole 20A.

[0026] The through hole 20A is defined by an outline line 30A. The through hole 20A includes a first outline line 31A and a second outline line 32A. The first outline line 31A is provided at the end of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided. The second outline line 32A is connected to both ends of the first outline line 31A. A part of the second outline line 32A is provided at a position away from the first outline line 31A in a direction from the end side of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided to the opposite side of the end side of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided. A part of the second outline line 32A is provided at a position away from the first outline line 31A in the fifth direction Y1. In the second outline line 32A, the second outline line 32A moves away from the part connected to the first outline line 31A in the fifth direction Y1 from the first outline line 31A. The second contour line 32A is provided on the lid 6B so as to form a semicircle when viewed in the first direction Z1.

[0027] As shown in Figures 2 and 3, the lock tab 7A is provided on the main body 3. The lock tab 7A is bendable in the fifth direction Y1 from the main body 3. As shown in Figure 4, the lock tab 7A has a rectangular shape when viewed in the first direction Z1. The lock tab 7A has an outer shape larger than the through hole 20A of the lid 6A. When viewed in the first direction Z1, the area of ​​the lock tab 7A is 1.1 to 1.5 times the area of ​​the through hole 20A.

[0028] The maximum length L11 of the lock tab 7A in the X direction is greater than the maximum length L12 of the lock tab 7A in the Y direction. The length L11 of the lock tab 7A is 1.2 to 2.5 times the length L12 of the lock tab 7A. Preferably, the length L11 of the lock tab 7A is 1.5 to 2.2 times the length L12 of the lock tab 7A. More preferably, the length L11 of the lock tab 7A is 1.8 to 2.0 times the length L12 of the lock tab 7A.

[0029] In this embodiment, the length L11 of the lock tab 7A is approximately the same as the length L1 of the through hole 20A, and the length L12 of the lock tab 7A is approximately the same as the length L2 of the through hole 20A. In this disclosure, "approximately" includes an error of 5% or more and 10% or less.

[0030] As shown in FIG. 2 and FIG. 4, the lock tab 7A has a plurality of folds 60. As shown in FIG. 4, the plurality of folds 60 have a linear shape. The plurality of folds 60 are arranged in a direction intersecting each other. When the lock tab 7A is in a state where the lock tab 7A locks the lid 6A, the plurality of folds 60 on the lock tab 7A are located inside the outline line 30A that defines the through hole 20A. As shown in FIG. 2, the lock tab 7A can be folded along the plurality of folds 60 in a second direction Z2 opposite to the first direction Z1. As shown in FIG. 4, the lock tab 7A folded along the plurality of folds 60 has a trapezoidal shape when viewed in the direction toward the first direction Z1. The lock tab 7A folded along the plurality of folds 60 is smaller than the through hole 20A of the lid 6A when viewed in the direction toward the first direction Z1.

[0031] When the lid 6A is closed on the main body 3 and the lock tab 7A is located on the first main surface 81 side of the lid 6A, the lock tab 7A is movable in the first direction Z1. When the lock tab 7A moves in the first direction Z1, the lock tab 7A is deformable. For example, when the lock tab 7A moves in the first direction Z1, the lock tab 7A is folded by 90 degrees or more along the multiple folds 60 toward the second direction Z2. By deforming the lock tab 7A, the lock tab 7A can be inserted into the through hole 20A of the lid 6A.

[0032] 5, when the lock tab 7A is inserted into the through hole 20A, the lock tab 7A is disposed on the second main surface 82 side of the lid 6A. When the lock tab 7A is inserted into the through hole 20A, the lock tab 7A moves in the first direction Z1 to return to the state before the lock tab 7A was inserted into the through hole 20A. When the lock tab 7A moves in the first direction Z1 while the lock tab 7A is inserted into the through hole 20A, at least a part of the lock tab 7A is capable of contacting the second main surface 82 of the lid 6A. In other words, when the lock tab 7A is inserted into the through hole 20A, at least a part of the lock tab 7A is disposed so as to be capable of contacting the second main surface 82 of the lid 6A.

[0033] 4, in a state where the lock tab 7A is disposed on the second main surface 82 side of the lid 6A, the through hole 20A is blocked by the lock tab 7A when the lid 6A is viewed in the first direction Z1. In a state where the lock tab 7A is inserted into the through hole 20A of the lid 6A, the through hole 20A is blocked by the lock tab 7A by a portion of the lock tab 7A located within the outline line 30A of the through hole 20A when the lid 6A is viewed in the first direction Z1. In the present disclosure, the blocking of the through hole 20A by the lock tab 7A refers to a state where the inside of the packaging material 2B cannot be seen through the through hole 20A when viewed in the first direction Z1.

[0034] The arm portion 8 allows the lock tab 7A to move in a sixth direction Y2 intersecting with the first direction Z1. When the lock tab 7A moves in the sixth direction Y2, the lock tab 7A can be pulled out of the through-hole 20A of the lid 6A in a locked state. When the lock tab 7A is pulled out of the through-hole 20A of the lid 6A in a locked state, the lock of the lid 6A is released.

[0035] The arm portion 8 is provided on the main body 3. The arm portion 8 is formed from a part of the main body 3. The arm portion 8 is connected to the lock tab 7A and is bendable in a sixth direction Y2 intersecting the first direction Z1. The arm portion 8 is bendable in the sixth direction Y2 from the main body 3. By bending the arm portion 8 in the sixth direction Y2, the lock tab 7A can be moved in the sixth direction Y2.

[0036] A packing method for packing an object with the packing material 2A according to this embodiment will be described.

[0037] The packaging method includes the steps of placing an object in a packaging material 2A and locking a lid 6A.

[0038] In the step of storing the object in the packaging material 2A, the object is stored in the packaging material 2A with the lid 6A open. For example, an electronic device is stored in the packaging material 2A.

[0039] After the step of storing the object in the packaging material 2A is completed, the step of locking the lid 6A is performed. In the step of locking the lid 6A, the lid 6A is locked by the lock tab 7A. The step of locking the lid 6A will be described.

[0040] In the step of locking the lid 6A, the lid 6A is closed onto the main body 3. The lid 6A is closed onto the main body 3 with the arm portion 8 bent in the sixth direction Y2.

[0041] Next, the lock tab 7A is positioned on the first main surface 81 side of the lid 6A. With the lid 6A closed relative to the main body 3, the arm portion 8 is changed from a state in which it is bent in the sixth direction Y2 to a state in which it is not bent in the sixth direction Y2, thereby positioning the lock tab 7A on the first main surface 81 side of the lid 6A. The lock tab 7A is positioned on the first main surface 81 side of the lid 6A so that the outer contour line 30A of the through hole 20A intersects with the lock tab 7A.

[0042] Next, with the lid 6A closed on the main body 3 and the lock tab 7A positioned on the first main surface 81 side of the lid 6A, the lock tab 7A is moved in the first direction Z1. When the user pushes the lock tab 7A in the first direction Z1, the lock tab 7A moves in the first direction Z1.

[0043] Next, the lock tab 7A is deformed to insert the lock tab 7A into the through hole 20A. The lock tab 7A is deformed to a size that allows it to be inserted into the through hole 20A, and the lock tab 7A is inserted into the through hole 20A. For example, the lock tab 7A is deformed by contacting a part of the lid 6B and receiving a force from the outside for moving in the first direction Z1. The lock tab 7A is bent in the second direction Z2 along the multiple folds 60 by contacting a part of the lid 6B and receiving a force from the outside for moving in the first direction Z1.

[0044] After the lock tab 7A is inserted into the through hole 20A, the lock tab 7A is disposed on the second main surface 82 side of the lid 6A. When disposed on the second main surface 82 side of the lid 6A, the lock tab 7A that was deformed when inserted into the through hole 20A returns to its original shape. For example, the lock tab 7A that was bent in the second direction Z2 along the multiple folds 60 when inserted into the through hole 20A deforms in a direction returning to its original shape from a state bent in the second direction Z2 when disposed on the second main surface 82 side of the lid 6A.

[0045] When the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, a portion of the lock tab 7A contacts the second main surface 82 of the lid 6A. A portion of the lock tab 7A that is deformed when inserted into the through hole 20A returns to its original shape, and a portion of the lock tab 7A contacts the second main surface 82 of the lid 6A. A portion of the lock tab 7A that is deformed when inserted into the through hole 20A contacts the second main surface 82 of the lid 6A. The lid 6A is locked by a portion of the lock tab 7A contacting the second main surface 82 of the lid 6A.

[0046] The object may be transported while being packed in the packaging material 2A. For example, an electronic device may be transported while being packed in the packaging material 2A.

[0047] The effects of the packaging material 2A according to this embodiment will be described.

[0048] The packaging material 2A includes a main body 3, a lid 6A provided on the main body 3 so as to be openable and closable, and a lock tab 7A provided on the main body 3. The lid 6A has a first main surface 81 and a second main surface 82 opposite to the first main surface 81. The lid 6A is provided with a through hole 20A penetrating in a first direction Z1 from the first main surface 81 toward the second main surface 82. The lock tab 7A has an outer shape larger than the through hole 20A of the lid 6A. When the lid 6A is closed with respect to the main body 3 and the lock tab 7A is positioned on the first main surface 81 side of the lid 6A, when the lock tab 7A moves in the first direction Z1, the lock tab 7A is inserted into the through hole 20A. The lock tab 7A is disposed on the second main surface 82 of the lid 6A.

[0049] With this configuration, the packaging material 2A can easily lock the lid 6A. Since the through hole 20A is provided in the lid 6A, when the lid 6A is closed relative to the main body 3, the lock tab 7A can be easily positioned on the first main surface 81 side of the lid 6A so that the outline line 30A of the through hole 20A intersects with the lock tab 7A. In addition, since the lock tab 7A is provided in the main body 3 of the packaging material 2A, when the lock tab 7A is positioned on the first main surface 81 side of the lid 6A, the outline line 30A of the through hole 20A intersects with the lock tab 7A. Therefore, the lock tab 7A can be aligned to a position intersecting with the through hole 20A by a simple operation.

[0050] Although the lock tab 7A has an outer shape larger than the through hole 20A, when the lock tab 7A is inserted into the through hole 20A, the lock tab 7A deforms, so that the lock tab 7A can be easily inserted into the through hole 20A. Furthermore, by inserting the lock tab 7A into the through hole 20A, the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, and the lid 6A can be locked.

[0051] As described above, the lid 6A of the packaging material 2A can be easily locked by a simple operation. Therefore, the operation of locking the lid 6A can be realized by a machine. Locking the lid 6A by a machine can improve the work efficiency.

[0052] With the lock tab 7A disposed on the second main surface 82 side of the lid 6A, the through hole 20A is blocked by the lock tab 7A when the lid 6A is viewed in the first direction Z1.

[0053] With this configuration, the inside of the packaging material 2A is hidden from view through the through hole 20A by the lock tab 7A.

[0054] The lock tab 7A has a plurality of folds 60 and is foldable along the plurality of folds 60 in a second direction Z2 opposite to the first direction Z1.

[0055] With this configuration, the lock tab 7A can be easily inserted into the through hole 20A. In addition, by folding the folds 60 in the second direction Z2, when the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, a part of the lock tab 7A comes into closer contact with the second main surface 82 of the through hole 20A, and the lid 6A can be locked more firmly.

[0056] The lock tab 7A folded along the creases 60 is smaller than the through hole 20A of the lid 6A when viewed in the first direction Z1.

[0057] With this configuration, when the lock tab 7A is moved in the first direction Z1 with the lock tab 7A positioned on the first main surface 81 side of the lid 6A, the lock tab 7A can be easily inserted into the through hole 20A.

[0058] When the lock tab 7A moves in the first direction Z1, the lock tab 7A folds along the multiple folds 60 by 90 degrees or more toward the second direction Z2.

[0059] When the lock tab 7A moves in the first direction Z1, the lock tab 7A is folded along the folds 60 by 90 degrees or more in the second direction Z2, making it easier for the lock tab 7A to be inserted into the through-hole 20A.

[0060] When the lid 6A is closed on the main body 3, as viewed in the first direction Z1, the through hole 20A of the lid 6A is provided on the end side of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided.

[0061] With this configuration, in the packaging material 2A with the lid 6A locked, it is possible to make it difficult for the lock tab 7A to come out of the through hole 20A due to an impact from outside the packaging material 2A.

[0062] When viewed in the first direction Z1, the through hole 20A is defined by an outline line 30A. The outline line 30A includes a first outline line 31A and a second outline line 32A. The first outline line 31A is provided on the end side of the lid 6A located on the side of the main body 3 on which the lock tab 7A is provided. At least a portion of the second outline line 32A is provided at a position spaced apart from the first outline line 31A in a direction from the end side of the lid 6A located on the side of the main body 3 on which the lock tab 7A is provided toward the opposite end side of the lid 6A located on the side of the main body 3 on which the lock tab 7A is provided.

[0063] With this configuration, the lock tab 7A can be more easily inserted into the through hole 20A defined by the outline line 30A. In addition, by making the lock tab 7A easier to insert, when the lock tab 7A is inserted into the through hole 20A, the portion of the lid 6A where the through hole 20A is provided is less likely to be torn due to the insertion of the lock tab 7A.

[0064] The packaging material 2A is provided on the main body 3, and further includes an arm portion 8 that is connected to the lock tab 7A and is bendable in a sixth direction Y2 that intersects with the first direction Z1.

[0065] With this configuration, when pulling out the lock tab 7A from the through hole 20A to unlock the lid 6A locked by the lock tab 7A, the lock tab 7A can be easily pulled out from the through hole 20A. In addition, since the packaging material 2A has the arm portion 8, the lock tab 7A can be moved in a direction away from the lid 6A, that is, in the sixth direction Y2, so that the lid 6A can be easily opened and closed with respect to the main body 3.

[0066] The blank sheet 1A can be folded to assemble the above-mentioned packaging material 2A.

[0067] With this configuration, the packaging material 2A can be assembled so that the lid 6A can be easily locked by folding the blank sheet 1A.

[0068] The packaging method is a method for packaging an object using the above-mentioned packaging material 2A. The packaging method includes a step of storing an object in the packaging material 2A and a step of locking the lid 6A. In the step of locking the lid 6A, the lock tab 7A is moved in the first direction Z1 in a state in which the lid 6A is closed relative to the main body 3 and the lock tab 7A is positioned on the first main surface 81 side of the lid 6A. At least one of the lock tab 7A and the through hole 20A is deformed to insert the lock tab 7A into the through hole 20A. After the lock tab 7A is inserted into the through hole 20A, the lock tab 7A is disposed on the second main surface 82 side of the lid 6A.

[0069] Packaging an object in the packaging material 2A allows the work of packaging the object to be carried out efficiently. The step of locking the packaging material 2A can also be carried out by machine. For example, when packaging an electronic device in the packaging material 2A by machine, the work from the step of manufacturing the electronic device to storing the electronic device in the packaging material 2A and locking the lid 6A of the packaging material 2A can all be carried out by machine. This allows the electronic device to be distributed efficiently in the market.

[0070] In the present embodiment, the blank sheet 1A is described as being made of cardboard, but is not limited thereto. For example, the blank sheet 1A may be made of cardboard, polypropylene sheet, or the like.

[0071] Although the packaging material 2A has been described as including the arm portion 8, the packaging material 2A does not necessarily have to include the arm portion 8.

[0072] The main body 3 may or may not have an opening.

[0073] The lid 6A may be capable of opening and closing the opening of the main body 3 having an opening.

[0074] Although the outer shape of the main body 3 has been described as a rectangular parallelepiped, the shape is not limited to this. For example, the main body 3 may be a pentagonal prism.

[0075] In the above description, the through hole 20A of the lid 6A is provided on the end side of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided when viewed in the first direction Z1 in a state in which the lid 6A is closed on the main body 3, but this is not limited to the above. For example, in the state in which the lid 6A is closed on the main body 3, the through hole 20A of the lid 6A may be provided on the side opposite the end side of the lid 6A located on the side of the main body 3 where the lock tab 7A is provided when viewed in the first direction Z1.

[0076] Although the through hole 20A has been described as having a semicircular shape when viewed in the first direction Z1, the shape is not limited thereto. For example, the through hole 20A may have a trapezoidal shape.

[0077] Although the length L1 of the through hole 20A has been described as being greater than the length L2 of the through hole 20A, the length L1 of the through hole 20A does not have to be greater than the length L2 of the through hole 20A.

[0078] Although the outline line 30A has been described as including the first outline line 31A and the second outline line 32A, this is not limiting. For example, the outline line 30A may include the first outline line 31A, a second outline line parallel to the first outline line 31A, and a plurality of third outline lines intersecting both ends of each of the first outline line 31A and the second outline line.

[0079] Although the lock tab 7A has been described as having a rectangular shape when viewed in the first direction Z1, this is not limited thereto. For example, the lock tab 7A may have a semicircular or triangular shape when viewed in the first direction Z1.

[0080] Although the lock tab 7A has been described as having an outer shape larger than the through hole 20A of the lid 6A, this is not limited thereto. For example, a part of the lock tab 7A may have an outer shape larger than the through hole 20A.

[0081] Although the length L11 of the lock tab 7A has been described as being greater than the length L12 of the lock tab 7A, the length L11 of the lock tab 7A does not have to be greater than the length L12 of the lock tab 7A.

[0082] Although the length L11 of the lock tab 7A is described as being substantially the same as the length L1 of the through hole 20A, this is not limiting. For example, the length L11 of the lock tab 7A may be longer than the length L1 of the through hole 20A.

[0083] Although the length L12 of the lock tab 7A is described as being substantially the same as the length L2 of the through hole 20A, this is not limiting. For example, the length L12 of the lock tab 7A may be smaller than the length L2 of the through hole 20A.

[0084] In addition, although the lock tab 7A has been described as having a plurality of folds 60, this is not limited thereto. The lock tab 7A does not have to have a plurality of folds 60, and the lock tab 7A may have a single fold 60.

[0085] Although the lock tab 7A folded along the creases 60 has been described as having a trapezoidal shape when viewed in the first direction Z1, this is not limiting. For example, the lock tab 7A folded along the creases 60 may have a triangular shape when viewed in the first direction Z1.

[0086] Although the example has been described in which the lock tab 7A is bent along the folds 60 by 90 degrees or more toward the second direction Z2 when the lock tab 7A moves in the first direction Z1, the present invention is not limited to this. For example, when the lock tab 7A moves in the first direction Z1, the lock tab 7A may be bent along the folds 60 by less than 90 degrees toward the second direction Z2.

[0087] In addition, in a state where the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, when the lid 6A is viewed in the direction toward the first direction Z1, the through hole 20A is blocked by the lock tab 7A. However, this is not limited to this. For example, in a state where the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, when the lid 6A is viewed in the direction toward the first direction Z1, the through hole 20A does not have to be blocked by the lock tab 7A.

[0088] Although an example in which an electronic device is packed in the packing material 2A has been described, the present invention is not limited to this. For example, a book may be packed in the packing material 2A.

[0089] Although it has been described that the lock tab 7A is deformed by contacting a part of the lid 6B and receiving an external force for moving in the first direction Z1, the present invention is not limited to this. For example, the lock tab 7A may be deformed by a user bending the lock tab 7A in the second direction Z2 along the folds 60.

[0090] The lid 6A may be provided with an insertion piece that can be bent in the first direction Z1 from the lid 6A. A slit may be provided on the insertion piece side at the connection portion between the lid 6A and the insertion piece. When the lid 6A is locked by the lock tab 7A, the lock of the lid 6A may be released by pulling the lock tab 7A out of the slit.

[0091] (Embodiment 2) Fig. 6 is a plan view of an example of a blank sheet 1B from which the packaging material according to the embodiment 2 can be assembled. Fig. 7 is a perspective view of an example of a packaging material 2B according to the embodiment 2.

[0092] In the second embodiment, a configuration different from the first embodiment will be described.

[0093] The packaging material 2B according to the second embodiment differs from the first embodiment in that when the lock tab 7B is inserted into the through hole 20B of the lid 6B, the through hole 20B is deformed.

[0094] (Blank sheet) By folding the blank sheet 1B shown in Fig. 6, it is possible to assemble the packaging material 2B shown in Fig. 7. The blank sheet 1B is folded along the fold lines 71 or cuts 75 to assemble the packaging material 2B.

[0095] (Packing materials) Fig. 8 is a perspective view of an example of a packaging material 2B according to embodiment 2. Fig. 8 is a perspective view of an example of the packaging material 2B in a state in which a lid 6B is locked. Fig. 9 is a plan view of the example of the packaging material 2B shown in Fig. 8.

[0096] As shown in FIG. 9, the through hole 20B has a trapezoidal shape when viewed in the first direction Z1. The through hole 20B is defined by an outline line 30B. When viewed in the first direction Z1, the outline line 30B includes a first outline line 31B, a second outline line 32B, a third outline line 33B, and a fourth outline line 34B. The second outline line 32B is substantially parallel to the first outline line 31B. The length of the second outline line 32B in the X direction is smaller than the length of the first outline line 31B in the X direction. The third outline line 33B intersects with the first outline line 31B and the second outline line 32B. The fourth outline line 34B intersects with the first outline line 31B and the second outline line 32B.

[0097] When viewed in the first direction Z1, a plurality of cuts are provided in the lid 6B from the outline line 30B that defines the through hole 20B in a direction away from the outline line 30B. When viewed in the first direction Z1, each of the cuts is linear. When viewed in the first direction Z1, the inside of the packaging material 2B is not visible through the cuts. The cuts include a first cut 41B and a second cut 42B adjacent to the first cut 41B. The first cut 41B and the second cut 42B each have a first end 45 connected to the outline line 30B of the through hole 20B of the lid 6B and a second end 46 opposite to the first end 45. The first cut 41B is provided from a portion where the second outline line 32B and the third outline line 33B intersect in a direction away from the outline line 30B. The second cut 42B is also provided from the intersection of the second contour line 32B and the fourth contour line 34B in a direction away from the contour line 30B.

[0098] The lid 6B has a plurality of folds. Each of the folds is linear. The folds are provided around the through hole 20A when viewed in the first direction Z1. The folds are provided at a position away from the outline line 30B of the through hole 20B. The folds include a linear first fold 51 extending in the X direction, and linear second folds 52 and third folds 53 extending in the Y direction. The second fold 52 and the third fold 53 face each other with the through hole 20A between them. An opening defined by the first outline line 31B, the first fold 51, the second fold 52, and the third fold 53 is larger than the outline shape of the lock tab 7B. A part of the lid 6B can be bent in the first direction Z1 along each of the first fold 51, the second fold 52, and the third fold 53. A part of the lid 6B is bendable along the first fold 51, the second fold 52 and the third fold 53 in the first direction Z1 by an angle of 90 degrees or less.

[0099] The first fold 51 is provided at a position away from the second outline line 32B. The first fold 51 is provided at a position away from the second outline line 32B in the fifth direction Y1. The first fold 51 is provided between the first cut 41B and the second cut. The first fold 51 intersects with the first cut 41B and the second cut 42B so as to be aligned with the through hole 20B. The first fold 51 is provided from the second end 46 of the first cut 41B to the second end 46 of the second cut 42B. The first fold 51 is approximately parallel to the second outline line 32B.

[0100] The second fold 52 is provided at a position away from the third outline line 33B. A part of the second fold 52 is provided at a position away from the third outline line 33B in the third direction X1. The second fold 52 intersects with the first cut 41B and the first outline line 31B on the lock tab 7B side of the lid 6B. The second fold 52 intersects with the second end 46 of the first cut 41B. The second fold 52 intersects with the first outline line 31B and the third outline line 33B at a portion where the first outline line 31B and the third outline line 33B intersect.

[0101] The first crease 51 and the second crease 52 are bent in the first direction Z1, whereby the first cut 41B opens.

[0102] The third fold 53 is provided at a position away from the fourth outline line 34B, and a part of the third fold 53 is provided at a position away from the fourth outline line 34B in the fourth direction X2. The third fold 53 intersects with the second cut 42B and the first outline line 31B on the lock tab 7B side of the lid 6B. The third fold 53 intersects with the second end 46 of the second cut 42B. The third fold 53 intersects with the first outline line 31B and the fourth outline line 34B at a portion where the first outline line 31B and the fourth outline line 34B intersect.

[0103] The first fold 51 and the third fold 53 are bent in the first direction Z1, whereby the second cut 42B widens.

[0104] An operation for locking the lid 6B of the packaging material 2B according to the second embodiment will be described.

[0105] With the lock tab 7B positioned on the first main surface 81 side of the lid 6B, the lock tab 7B is moved in the first direction Z1. When the lock tab 7B moves in the first direction Z1, the through hole 20B is deformed, and the lock tab 7B is inserted into the through hole 20B. When the lock tab 7B moves in the first direction Z1, the through hole 20B becomes larger when viewed in the direction toward the first direction Z1 than before the lock tab 7B was inserted into the through hole 20B. The through hole 20B becomes larger as a result of a portion of the lid 6B bending in the first direction Z1.

[0106] When the lock tab 7A is inserted into the through hole 20B, the portion of the lid 6B where the multiple slits are provided is bent in the first direction Z1. When the lock tab 7B is inserted into the through hole 20B, the lid 6B is bent along the first fold 51, the second fold 52, and the third fold 53 at an angle in the first direction Z1 compared to before the lock tab 7B was inserted into the through hole 20B. For example, when the lock tab 7B is inserted into the through hole 20B, the lid 6B is bent at an angle of 90 degrees or more in the first direction Z1 along the first fold 51, the second fold 52, and the third fold 53. The multiple slits, that is, the first slit 41B and the second slit 42B, are each further opened by the lock tab 7A being inserted into the through hole 20B.

[0107] When the lock tab 7B is inserted into the through-hole 20B, the lock tab 7B is disposed on the second main surface 82 side of the lid 6B. The lid 6B is locked by a portion of the lock tab 7B contacting the second main surface 82 of the lid 6B. Furthermore, the first slit 41B and the second slit 42B are closed by a portion of the lock tab 7B contacting the second main surface 82 of the lid 6B.

[0108] The effects of the packaging material 2B according to this embodiment will be described.

[0109] The packaging material 2B includes a main body 3, a lid 6B provided on the main body 3 so as to be able to open and close, and a lock tab 7B provided on the main body 3. The lid 6B has a first main surface 81 and a second main surface 82 opposite to the first main surface 81. The lid 6B is provided with a through hole 20B penetrating in a first direction Z1 from the first main surface 81 toward the second main surface 82. When viewed in the first direction Z1, a first cut 41B and a second cut 42B are provided in the lid 6B from an outline line 30B that defines the through hole 20B toward a direction away from the outline line 30B. The lock tab 7B has an outline shape larger than the through hole 20B of the lid 6B. When the lid 6B is closed on the main body 3 and the lock tab 7B is located on the first main surface 81 side of the lid 6B, if the lock tab 7B moves in the first direction Z1, the through hole 20B is deformed and the lock tab 7B is inserted into the through hole 20B. When the lock tab 7B is inserted into the through hole 20B, the lock tab 7B is positioned on the second main surface 82 side of the lid 6B.

[0110] With this configuration, the packaging material 2B can easily lock the lid 6B. Furthermore, by providing the first slit 41B and the second slit 42B in the lid 6B, when the lock tab 7A is moved in the first direction Z1 with the lock tab 7B positioned on the first main surface 81 side of the lid 6B, the through hole 20B becomes easily deformed. Since the through hole 20B is easily deformed, the lock tab 7B can be easily inserted into the through hole 20B.

[0111] The outline line 30B of the through hole 20B includes a second outline line 32B and a third outline line 33B that intersects with the second outline line 32B when viewed in the first direction Z1. The first cut 41B is provided from the intersection of the second outline line 32B and the third outline line 33B in a direction away from the outline line 30B.

[0112] With this configuration, when the lock tab 7B is positioned on the first main surface 81 side of the lid 6B and the lock tab 7B is moved in the first direction Z1, the through hole 20B becomes more easily deformed, and the lock tab 7B becomes more easily inserted into the through hole 20B.

[0113] When the lock tab 7B is inserted into the through-hole 20B, the portion of the lid 6B where the first slit 41B and the second slit 42B are provided is bent in the first direction Z1.

[0114] With this configuration, when the locking tab 7B is inserted into the through hole 20B and positioned on the second main surface 82 side of the lid 6B, a portion of the locking tab 7B comes into closer contact with the second main surface 82 of the through hole 20A, thereby more firmly locking the lid 6B.

[0115] When the lid 6B is closed relative to the main body 3, as viewed in the first direction Z1, the through hole 20B of the lid 6B is provided at the end of the lid 6B located on the side of the main body 3 where the lock tab 7B of the main body 3 is provided. The lid 6B has a first fold 51. The first fold 51 is provided at a position away from the outline line 30B of the through hole 20B. The first fold 51 intersects with the first cut 41B and the second cut 42B so as to follow the through hole 20B. A part of the lid 6B is bendable in the first direction Z1 along the first fold 51.

[0116] With this configuration, when the lock tab 7B is positioned on the first main surface 81 side of the lid 6B and the lock tab 7B is moved in the first direction Z1, the through hole 20B becomes more easily deformed, and the lock tab 7B becomes more easily inserted into the through hole 20B.

[0117] A part of the lid 6B is bendable along the first fold 51 in the first direction Z1 by 90 degrees or less.

[0118] With this configuration, when the lock tab 7B of the lid 6B is inserted into the through hole 20B and the lock tab 7B moves in the first direction Z1, the lock tab 7B becomes less likely to come out of the through hole 20B. By making it more difficult for the lock tab 7B to come out of the through hole 20B, the lid 6B can be maintained in a locked state.

[0119] The first fold 51 is provided between two adjacent cuts, that is, between the first cut 41B and the second cut 42B.

[0120] With this configuration, when the lock tab 7B is moved in the first direction Z1 with the lock tab 7B positioned on the first main surface 81 side of the lid 6B, the through hole 20B is more likely to deform than the outer shape of the lock tab 7B. Since the through hole 20B is more likely to deform than the outer shape of the lock tab 7B, the lock tab 7B is more likely to be inserted into the through hole 20B.

[0121] The first cut 41B and the second cut 42B each have a first end 45 connected to the outline line 30B of the through-hole 20B of the lid 6B and a second end 46 opposite the first end 45. The first fold 51 is provided from the second end 46 of the first cut 41B to the second end 46 of the second cut 42B.

[0122] With this configuration, when the lock tab 7B is moved in the first direction Z1, a part of the lid 6B is bent in the first direction Z1 along the first fold 51, and the through hole 20B is deformed to become larger. The enlargement of the through hole 20B makes it easier for the lock tab 7B to be inserted into the through hole 20B.

[0123] The lid 6B has a second fold 52 and a third fold 53. The second fold 52 and the third fold 53 are provided at positions away from the outline 30B of the through hole 20B. The second fold 52 intersects with the first cut 41B and the outline 30B of the end of the lid 6B located on the side of the main body 3 where the lock tab 7B is provided. The third fold 53 intersects with the second cut 42B and the outline 30B of the end of the lid 6B located on the side of the main body 3 where the lock tab 7B is provided. A part of the lid 6B can be bent in the first direction Z1 along the second fold 52 and the third fold 53.

[0124] With this configuration, when the lock tab 7B is positioned on the first main surface 81 side of the lid 6B and the lock tab 7B is moved in the first direction Z1, the through hole 20B becomes more easily deformed, and the lock tab 7B becomes more easily inserted into the through hole 20B.

[0125] 6 illustrates that the blank sheet 1B has the first fold 51, the second fold 52, and the third fold 53, but this is not limited to this. For example, the blank sheet 1B does not have to have the second fold 52 and the third fold 53.

[0126] Although the lid 6B has been described as having a plurality of slits, i.e., the first slit 41B and the second slit 42B, the present invention is not limited to this. For example, the lid 6B may have one slit, for example, the first slit 41B.

[0127] Although it has been described that the inside of the packaging material 2B cannot be seen through the multiple slits when viewed in the first direction Z1, the inside of the packaging material 2B may be seen through the multiple slits when viewed in the first direction Z1. Furthermore, when the lock tab 7B is not inserted into the through hole 20B, the inside of the packaging material 2B may not be seen through the multiple slits when viewed in the first direction Z1. When the lock tab 7B is inserted into the through hole 20B, the inside of the packaging material 2B may not be seen through the multiple slits when viewed in the first direction Z1.

[0128] Although the lid 6B has been described as having a plurality of folds, the lid 6B does not necessarily have to have a plurality of folds. For example, the lid 6B does not necessarily have to have the first fold 51, the second fold 52, and the third fold 53.

[0129] Although the lid 6B has been described as having the first fold 51, the second fold 52, and the third fold 53, this is not limiting. For example, the lid 6B does not have to have the second fold 52 and the third fold 53.

[0130] Although the length in the X direction of the second outline line 32B has been described as being shorter than the length in the X direction of the first outline line 31B, this is not limited thereto. For example, the length in the X direction of the second outline line 32B may be longer than the length in the X direction of the first outline line 31B.

[0131] Although it has been described that a portion of the lid 6B is bent at an angle of 90 degrees or less in the first direction Z1 along the first fold 51, the second fold 52, and the third fold 53, this is not limiting. For example, a portion of 6B may be bent at an angle of more than 90 degrees in the first direction Z1 along the first fold 51, the second fold 52, and the third fold 53.

[0132] Although it has been described that the first fold 51 intersects with the first cut 41B and the second cut 42B so as to follow the through-hole 20B, the first fold 51 does not have to follow the through-hole 20B.

[0133] Although the first fold 51 has been described as being substantially parallel to the second outline line 32B, the first fold 51 does not have to be substantially parallel to the second outline line 32B.

[0134] Although the first slit 41B is described as being opened by bending the first fold 51 and the second fold 52 in the first direction Z1, the present invention is not limited to this. For example, the first slit 41B may be opened in a state where the first fold 51 and the second fold 52 are not bent in the first direction Z1.

[0135] Although the second slit 42B is described as being opened by bending the first fold 51 and the third fold 53 in the first direction Z1, the present invention is not limited to this. For example, the second slit 42B may be opened in a state where the first fold 51 and the third fold 53 are not bent in the first direction Z1.

[0136] <Variation 1> FIG. 10 is a perspective view of a packaging material 2C of the first modification.

[0137] As shown in FIG. 10, the structure of the lock tab 7A of the packaging material 2C of modified example 1 is the same as that of the packaging material 2A and the lock tab 7A of embodiment 1, and the structure of the lid 6B of the packaging material 2C of modified example 1 is the same as that of the lid 6B of the packaging material 2B of embodiment 2.

[0138] When the lid 6B is closed on the main body 3 and the lock tab 7A is located on the first main surface 81 side of the lid 6B, when the lock tab 7A moves in the first direction Z1, the lock tab 7A and the through hole 20B are deformed.

[0139] When the lock tab 7A moves in the first direction Z1, at least one of the lock tab 7A and the through hole 20B is deformed, making it easier to insert the lock tab 7A into the through hole 20B.

[0140] <Variation 2> FIG. 11 is a plan view of a packaging material 2D of the second modification.

[0141] Modification 2 differs from embodiment 1 in that a protrusion 62 is provided on a lock tab 7C of a packaging material 2D.

[0142] 11, the lock tab 7C of the packaging material 2B is provided with a protrusion 62. The protrusion 62 is provided at the tip portion of the lock tab 7C. When the lock tab 7C is inserted into the through hole 20A, the protrusion 62 bends from the lock tab 7C in the second direction Z2. When the lock tab 7C is disposed on the second main surface 82 side of the lid 6A, the protrusion 62 of the lock tab 7C is disposed on the second main surface 82 of the lid 6A.

[0143] Since the lock tab 7C has the protrusion 62, the lid 6A is more firmly locked by the lock tab 7C.

[0144] <Variation 3> FIG. 12 is a plan view of a lid 6C of a packaging material according to the third modification.

[0145] The third modification is different from the first embodiment in that a plurality of slits 43 are provided in the lid 6A of the packaging material.

[0146] 12, when viewed in the first direction Z1, a plurality of slits 43 are provided in the cover 6A, which extend from the outline line 30A that defines the through hole 20A in a direction away from the second outline line 32A. The plurality of slits 43 are provided at intervals along the second outline line 32A.

[0147] With this configuration, when the lock tab 7A is inserted into the through hole 20A, the lock tab 7A and the through hole 20A are deformed, so that the lock tab 7A can be easily inserted into the through hole 20A.

[0148] <Modification 4> FIG. 13 is a plan view of a packaging material 2E of the fourth modification.

[0149] Variation 4 differs from embodiment 2 in that the lid 6E of the packaging material 2E does not have a second fold 52 and a third fold 53, and that when viewed in a direction toward the first direction Z1 along the multiple slits, the inside of the packaging material 2E is visible.

[0150] 13, the lid 6E has a first cut 41E and a second cut 42E. When the first cut 41E and the second cut 42E are viewed in the first direction Z1, the inside of the packaging material is visible. Each of the first cut 41E and the second cut 42E has a first end 45 connected to the outer shape line 30B of the through hole 20B of the lid 6E and a second end 46 opposite the first end 45.

[0151] The first cut 41E has a width in a direction intersecting a direction from the first end 45 to the second end 46 of the first cut 41E. For example, the first cut 41E has a width of 0.5 mm to 10.0 mm in a direction intersecting a direction from the first end 45 to the second end 46 of the first cut 41E. Preferably, the first cut 41E has a width of 0.8 mm to 6.0 mm in a direction intersecting a direction from the first end 45 to the second end 46 of the first cut 41E. More preferably, the first cut 41E has a width of 1.0 mm to 3.0 mm in a direction intersecting a direction from the first end 45 to the second end 46 of the first cut 41E.
