Modes for Carrying Out the Invention

[0011] (Background Leading to the Present Disclosure) In the packaging material described in Patent Document 1, an opening / closing lid is connected to the opening side of a box body, and an insertion piece protrudes from the opening / closing lid. At the connecting portion between the opening / closing lid and the insertion piece, a slit portion is provided on the insertion piece side. Further, a locking piece having an insertion portion is formed on the box body. With the opening / closing lid closed and the insertion piece protruding from the opening / closing lid inserted inside the box body, the opening / closing lid is locked in the closed position by inserting the insertion portion of the locking piece into the slit portion.

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

[0013] However, in the packaging material described in Patent Document 1, the slit is located on the insertion side of the connecting portion between the opening / closing lid and the insertion piece, making it difficult to align the insertion piece with the slit. Therefore, even when the insertion part is aligned with the slit, it is difficult to insert the insertion piece into the slit. Furthermore, it is cumbersome for the user to move the insertion piece away from the slit before inserting it into the slit.

[0014] Furthermore, in the packaging material described in Patent Document 1, the insertion portion is smaller than the slit portion, but because 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] Therefore, in order to solve the above problem, the present inventors investigated a packaging material that allows the lid to be easily locked, which led to this disclosure.

[0016] Embodiment 1 of this disclosure will be described below with reference to the attached drawings. In addition, in each drawing, the elements are exaggerated to facilitate the explanation.

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

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

[0019] (Blank sheet) The blank sheet 1A shown in Figure 1 can be folded to assemble the packaging material 2A shown in Figure 2. The blank sheet 1A is folded along the fold lines 71 or cuts 75 to assemble the packaging material 2A. The blank sheet 1A shown in Figure 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 intermittent cuts may be formed in the creases. For example, the blank sheet 1A may be made of corrugated cardboard.

[0020] (Packaging materials) The packaging material 2A according to this embodiment 1 will now be described.

[0021] Figure 3 is a perspective view of an example of packaging material 2A according to Embodiment 1. Figure 3 is a perspective view of an example of packaging material 2A with the lid 6A locked. Figure 4 is a plan view of the example of packaging material 2A shown in Figure 3. Figure 5 is an enlarged cross-sectional perspective view of the packaging material 2A shown in Figure 3, cut along line AA.

[0022] As shown in Figures 2 and 3, the packaging material 2A comprises a main body 3, a lid 6A, a locking 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 is box-shaped. The external 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 that penetrates in a first direction Z1 from the first main surface 81 toward the second main surface 82. When viewing the lid 6A in the 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 the direction from the second direction Z2 toward the first direction Z1 means viewing it in the direction along the direction from the first main surface 81 toward the second main surface 82 of the lid 6A. Hereafter, "the direction from the second direction Z2 toward the first direction Z1" will be rephrased as "the direction toward the first direction Z1" in the explanation.

[0025] As shown in Figure 4, when the lid 6A is closed to the body 3, and the packaging material 2A is viewed in the direction toward the first direction Z1, the through hole 20A of the lid 6A is located on the end side of the lid 6A that is on the side of the body 3 where the lock tab 7A is provided. When viewed in the direction toward the first direction Z1, the through hole 20A has a semicircular shape. When viewed in the direction toward 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 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 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 the length L2 of the through hole 20A.

[0026] The through-hole 20A is defined by the 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 body 3 side where the lock tab 7A is provided. The second outline line 32A connects to each of the ends of the first outline line 31A. A portion of the second outline line 32A is provided at a position away from the first outline line 31A in the direction from the end of the lid 6A located on the body 3 side where the lock tab 7A is provided toward the opposite side of the end of the lid 6A located on the body 3 side where the lock tab 7A is provided. A portion of the second outline line 32A is provided at a position away from the first outline line 31A in a fifth direction Y1. In the second outline line 32A, as it moves away from the portion connected to the first outline line 31A, it moves away from the first outline line 31A in a fifth direction Y1. The second outer shape line 32A is provided on the lid 6B so as to form a semicircle when viewed in the direction toward 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 from the main body 3 in the fifth direction Y1. As shown in Figure 4, when viewed in the direction toward the first direction Z1, the lock tab 7A has a rectangular shape. The lock tab 7A has an outer shape that is larger than the through hole 20A of the lid 6A. When viewed in the direction toward the first direction Z1, the area of ​​the lock tab 7A is 1.1 times or more and 1.5 times or less 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 times or more and 2.5 times or less the length L12 of the lock tab 7A. Preferably, the length L11 of the lock tab 7A is 1.5 times or more and 2.2 times or less the length L12 of the lock tab 7A. More preferably, the length L11 of the lock tab 7A is 1.8 times or more and 2.0 times or less 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% to 10%.

[0030] As shown in Figures 2 and 4, the lock tab 7A has a plurality of folds 60. As shown in Figure 4, the plurality of folds 60 have a linear shape. The plurality of folds 60 are arranged in directions that intersect each other. When the lock tab 7A is locking the lid 6A, the plurality of folds 60 provided on the lock tab 7A are located inside the outline line 30A that defines the through hole 20A. As shown in Figure 2, the lock tab 7A is bendable along the plurality of folds 60 in a second direction Z2 opposite to the first direction Z1. As shown in Figure 4, the lock tab 7A bent along the plurality of folds 60 has a trapezoidal shape when viewed in the direction toward the first direction Z1. The lock tab 7A bent 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] With the lid 6A closed against the body 3 and the lock tab 7A positioned 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, it is deformable. For example, when the lock tab 7A moves in the first direction Z1, it bends toward the second direction Z2 by more than 90 degrees along the multiple folds 60. By deforming the lock tab 7A, it becomes possible to insert the lock tab 7A into the through hole 20A of the lid 6A.

[0032] As shown in Figure 5, when the lock tab 7A is inserted into the through hole 20A, the lock tab 7A is positioned on the side of the second main surface 82 of the lid 6A. When the lock tab 7A is inserted into the through hole 20A, it moves in the first direction Z1 in an attempt to return to its state before insertion into the through hole 20A. When the lock tab 7A moves in the first direction Z1 while inserted into the through hole 20A, at least a portion of the lock tab 7A becomes able to contact 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 portion of the lock tab 7A is positioned to be able to contact the second main surface 82 of the lid 6A.

[0033] As shown in Figure 4, when the lock tab 7A is positioned 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. When the lock tab 7A is inserted into the through hole 20A of the lid 6A, the portion of the lock tab 7A located within the outer shape line 30A of the through hole 20A blocks the through hole 20A when the lid 6A is viewed in the first direction Z1. In this disclosure, the state in which the through hole 20A is blocked by the lock tab 7A means that when viewed in the first direction Z1, the inside of the packaging material 2B cannot be seen from the through hole 20A.

[0034] The arm portion 8 makes the lock tab 7A movable in a sixth direction Y2 that intersects the first direction Z1. When the lock tab 7A moves in the sixth direction Y2, the lock tab 7A can be pulled out from the through hole 20A of the lid 6A while the lid 6A is locked. When the lid 6A is locked, pulling out the lock tab 7A from the through hole 20A of the lid 6A releases the lock on the lid 6A.

[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 connects to the lock tab 7A and is bendable in a sixth direction Y2 that intersects the first direction Z1. The arm portion 8 is bendable from the main body 3 in the sixth direction Y2. 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 packaging method for packaging an object using the packaging material 2A according to this embodiment will be described.

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

[0038] In the step of placing the object inside the packaging material 2A, the object is placed inside the packaging material 2A with the lid 6A open. For example, electronic equipment is placed inside the packaging material 2A.

[0039] After completing the step of placing the object in packaging material 2A, 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 explained below.

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

[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 body 3, the lock tab 7A is positioned on the first main surface 81 side of the lid 6A by changing the arm portion 8 from a state where it is bent in the sixth direction Y2 to a state where it is not bent in the sixth direction Y2. The lock tab 7A is positioned on the first main surface 81 side of the lid 6A such that the outer outline line 30A of the through hole 20A intersects with the lock tab 7A.

[0042] Next, with the lid 6A closed relative to 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. The lock tab 7A moves in the first direction Z1 when the user pushes it in that direction.

[0043] Next, the lock tab 7A is deformed and inserted into the through hole 20A. The lock tab 7A is deformed to a size that can be inserted into the through hole 20A and inserted into the through hole 20A. For example, the lock tab 7A is deformed by contacting a part of the lid 6B and receiving an external force to move 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 an external force to move in the first direction Z1.

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

[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. The portion of the lock tab 7A that was deformed when inserted into the through hole 20A returns to its original shape, causing a portion of the lock tab 7A to contact the second main surface 82 of the lid 6A. The portion of the lock tab 7A that was 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] Furthermore, the object may be transported while packaged in packaging material 2A. For example, electronic equipment may be transported while packaged in packaging material 2A.

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

[0048] The packaging material 2A comprises a main body 3, a lid 6A that is openable and closable on the main body 3, 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 that penetrates in a first direction Z1 from the first main surface 81 to 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 relative to the main body 3 and the lock tab 7A is positioned on the first main surface 81 side of the lid 6A, the lock tab 7A moves in the first direction Z1, and the lock tab 7A is inserted into the through hole 20A. The lock tab 7A is positioned on the second main surface 82 of the lid 6A.

[0049] With this configuration, the packaging material 2A can easily lock the lid 6A. Because the through hole 20A is provided in the lid 6A, when the lid 6A is closed to the body 3, it is easy to position the lock tab 7A on the first main surface 81 side of the lid 6A so that the outer outline 30A of the through hole 20A intersects with the lock tab 7A. Furthermore, since the lock tab 7A is provided in the 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 outer outline 30A of the through hole 20A intersects with the lock tab 7A. Therefore, the lock tab 7A can be aligned to intersect with the through hole 20A with a simple operation.

[0050] Although the lock tab 7A has a larger external shape than the through hole 20A, it can be easily inserted into the through hole 20A because the lock tab 7A deforms when inserted into the through hole 20A. Furthermore, by inserting the lock tab 7A into the through hole 20A, it is positioned on the second main surface 82 side of the lid 6A, thereby locking the lid 6A.

[0051] As described above, the packaging material 2A can easily lock the lid 6A with a simple action. Therefore, the action of locking the lid 6A can also be performed by machine. By locking the lid 6A by machine, work efficiency can be improved.

[0052] With the lock tab 7A positioned 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 direction toward the first direction Z1.

[0053] With this configuration, the inside of the packaging material 2A is not visible from the through-hole 20A due to the lock tab 7A.

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

[0055] This configuration makes it easier to insert the lock tab 7A into the through hole 20A. Furthermore, by bending the multiple 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 portion of the lock tab 7A makes better contact with the second main surface 82 of the through hole 20A, allowing the lid 6A to be locked more securely.

[0056] The lock tab 7A, bent along multiple folds 60, is smaller than the through hole 20A of the lid 6A when viewed in the direction toward the first direction Z1.

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

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

[0059] As the lock tab 7A moves in the first direction Z1, the lock tab 7A bends by more than 90 degrees toward the second direction Z2 along the multiple folds 60, making it easier for the lock tab 7A to be inserted into the through hole 20A.

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

[0061] With this configuration, when the lid 6A is locked in the packaging material 2A, the lock tab 7A is less likely to come out of the through hole 20A due to impact from the outside of the packaging material 2A.

[0062] Viewed in the direction toward the first direction Z1, the through hole 20A is defined by the 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 body 3 side where the lock tab 7A is provided. The second outline line 32A is provided at least in part at a distance from the first outline line 31A in the direction toward the opposite side of the end side of the lid 6A located on the body 3 side where the lock tab 7A is provided.

[0063] This configuration makes it easier to insert the lock tab 7A into the through hole 20A defined in the outer shape line 30A. Furthermore, because the lock tab 7A is 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 located is less likely to tear due to the insertion of the lock tab 7A.

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

[0065] This configuration makes it easier to pull the lock tab 7A out of the through hole 20A in order to unlock the lid 6A that is locked by the lock tab 7A. In addition, because the packaging material 2A has an arm portion 8, the lock tab 7A can be moved away from the lid 6A, that is, in the sixth direction Y2, making it easier to open and close the lid 6A relative to the main body 3.

[0066] The blank sheet 1A can be folded, allowing the aforementioned packaging material 2A to be assembled.

[0067] With this configuration, the blank sheet 1A can be folded, allowing for the assembly of packaging material 2A that can easily lock the lid 6A.

[0068] The packaging method is a method of packaging the object using the packaging material 2A described above. The packaging method includes the steps of placing the object inside the packaging material 2A and locking the lid 6A. In the step of locking the lid 6A, with the lid 6A closed to 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. 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 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.

[0069] By packaging the object with packaging material 2A, the packaging process can be carried out efficiently. Furthermore, the process of locking packaging material 2A can also be performed by machine. For example, when packaging electronic equipment with packaging material 2A using a machine, all processes from the manufacturing of the electronic equipment to placing the electronic equipment in packaging material 2A and locking the lid 6A of packaging material 2A can be performed by machine. As a result, electronic equipment can be efficiently distributed to the market.

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

[0071] Although it was explained that packaging material 2A includes an arm portion 8, packaging material 2A does not necessarily have to include an arm portion 8.

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

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

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

[0075] It has been explained that, when the lid 6A is closed to the main body 3, the through hole 20A of the lid 6A is located on the end of the lid 6A that is on the side of the main body 3 where the lock tab 7A is provided, when viewed in the direction toward the first direction Z1, but this is not limited to this. For example, when the lid 6A is closed to the main body 3, the through hole 20A of the lid 6A may be located on the opposite side of the end of the lid 6A that is on the side of the main body 3 where the lock tab 7A is provided, when viewed in the direction toward the first direction Z1.

[0076] Although it has been explained that the through-hole 20A has a semicircular shape when viewed in the direction toward the first direction Z1, it is not limited to this. For example, the through-hole 20A may have a trapezoidal shape.

[0077] Although it was explained that the length L1 of the through-hole 20A is greater than the length L2 of the through-hole 20A, the length L1 of the through-hole 20A does not necessarily have to be greater than the length L2 of the through-hole 20A.

[0078] Although it has been explained that the outline line 30A includes the first outline line 31A and the second outline line 32A, it is not limited to these. 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 the first outline line 31A and the second outline line.

[0079] Although it has been explained that the lock tab 7A has a rectangular shape when viewed in the direction toward the first direction Z1, it is not limited to this. For example, the lock tab 7A may have a semicircular shape or a triangular shape when viewed in the direction toward the first direction Z1.

[0080] Although it has been explained that the lock tab 7A has an external shape larger than the through hole 20A of the lid 6A, this is not limited to this. For example, a portion of the lock tab 7A may have an external shape larger than the through hole 20A.

[0081] Although it was explained that the length L11 of the lock tab 7A is greater than the length L12 of the lock tab 7A, the length L11 of the lock tab 7A does not necessarily have to be greater than the length L12 of the lock tab 7A.

[0082] Although it was explained that the length L11 of the lock tab 7A is approximately the same as the length L1 of the through hole 20A, this is not the only explanation. For example, the length L11 of the lock tab 7A may be longer than the length L1 of the through hole 20A.

[0083] Although it was explained that the length L12 of the lock tab 7A is approximately the same as the length L2 of the through hole 20A, this is not the only explanation. For example, the length L12 of the lock tab 7A may be smaller than the length L2 of the through hole 20A.

[0084] Although it has been explained that the lock tab 7A has multiple folds 60, it is not limited to this. The lock tab 7A does not have to have multiple folds 60, and the lock tab 7A may have only one fold 60.

[0085] Although it has been explained that the lock tab 7A folded along multiple folds 60 is trapezoidal in shape when viewed in the direction toward the first direction Z1, it is not limited to this. For example, the lock tab 7A folded along multiple folds 60 may be triangular in shape when viewed in the direction toward the first direction Z1.

[0086] In the example described, when the lock tab 7A moves in the first direction Z1, the lock tab 7A bends toward the second direction Z2 at an angle of 90 degrees or more along the multiple folds 60, but this is not the only example. For example, when the lock tab 7A moves in the first direction Z1, the lock tab 7A may bend toward the second direction Z2 at an angle of less than 90 degrees along the multiple folds 60.

[0087] It has been explained that when the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, the through hole 20A is blocked by the lock tab 7A when viewed in the direction toward the first direction Z1, but this is not limited to this. For example, when the lock tab 7A is positioned on the second main surface 82 side of the lid 6A, the through hole 20A does not have to be blocked by the lock tab 7A when viewed in the direction toward the first direction Z1.

[0088] While the example of packaging electronic devices in packaging material 2A was described, this is not the only example. For example, books could also be packaged in packaging material 2A.

[0089] It has been explained that the lock tab 7A deforms when it comes into contact with a part of the lid 6B and receives an external force that causes it to move in the first direction Z1, but this is not the only way in which it can deform. For example, the lock tab 7A may deform when the user bends the lock tab 7A in the second direction Z2 along multiple folds 60.

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

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

[0092] Embodiment 2 describes a configuration that differs from that of Embodiment 1.

[0093] The packaging material 2B according to Embodiment 2 differs from Embodiment 1 in that the through hole 20B deforms when the lock tab 7B is inserted into the through hole 20B of the lid 6B.

[0094] (Blank sheet) The packaging material 2B shown in Figure 7 can be assembled by folding the blank sheet 1B shown in Figure 6. The packaging material 2B is assembled by folding the blank sheet 1B along the fold line 71 or cut line 75.

[0095] (Packaging materials) Figure 8 is a perspective view of an example of packaging material 2B according to Embodiment 2. Figure 8 is a perspective view of an example of packaging material 2B with the lid 6B locked. Figure 9 is a plan view of the example of packaging material 2B shown in Figure 8.

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

[0097] Viewed in the direction toward the first direction Z1, multiple cuts are provided in the lid 6B, extending away from the outline line 30B that defines the through hole 20B. Viewed in the direction toward the first direction Z1, each of the multiple cuts is straight. Viewed in the direction toward the first direction Z1, the inside of the packaging material 2B is not visible from the multiple cuts. The multiple 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 on the opposite side of the first end 45. The first cut 41B is provided in the direction away from the outline line 30B, from the point where the second outline line 32B and the third outline line 33B intersect. Furthermore, the second cut 42B is also provided in a direction away from the outer shape line 30B, starting from the point where the second outer shape line 32B and the fourth outer shape line 34B intersect.

[0098] The lid 6B has multiple folds. Each of the multiple folds is linear. The multiple folds are provided around the through hole 20A when viewed in the direction toward the first direction Z1. The multiple folds are provided at positions away from the outline line 30B of the through hole 20B. The multiple 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 third folds 53 face each other with the through hole 20A in between. The 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 portion of the lid 6B is bendable in the first direction Z1 along each of the first folds 51, the second fold 52, and the third fold 53. A portion of the lid 6B can be 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.

[0099] The first fold 51 is located away from the second outline line 32B. The first fold 51 is located away from the second outline line 32B in the fifth direction Y1. The first fold 51 is located between the first cut 41B and the second cut. The first fold 51 intersects the first cut 41B and the second cut 42B along the through hole 20B. The first fold 51 is located 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 located away from the third outline line 33B. A portion of the second fold 52 is located away from the third outline line 33B in the third direction X1. The second fold 52 intersects the first cut 41B and the first outline line 31B on the side of the lock tab 7B of the lid 6B. The second fold 52 intersects the second end 46 of the first cut 41B. At the point where the first outline line 31B and the third outline line 33B intersect, the second fold 52 intersects the first outline line 31B and the third outline line 33B.

[0101] The first fold 51 and the second fold 52 bend in the first direction Z1, causing the first cut 41B to open.

[0102] The third fold 53 is located away from the fourth outline line 34B, and a portion of the third fold 53 is located 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 side of the lock tab 7B of the lid 6B. The third fold 53 intersects with the second end 46 of the second cut 42B. At the point where the first outline line 31B and the fourth outline line 34B intersect, the third fold 53 intersects with the first outline line 31B and the fourth outline line 34B.

[0103] As the first fold 51 and the third fold 53 bend in the first direction Z1, the second cut 42B widens.

[0104] The operation for locking the lid 6B of the packaging material 2B according to Embodiment 2 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 deforms 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 of the first direction Z1 than before the lock tab 7B was inserted into the through hole 20B. The through hole 20B becomes larger because a part of the lid 6B bends in the first direction Z1.

[0106] When the lock tab 7A is inserted into the through hole 20B, the portion of the lid 6B with multiple slits bends in the first direction Z1. When the lock tab 7B is inserted into the through hole 20B, the lid 6B bends 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 bends along the first fold 51, the second fold 52, and the third fold 53 at an angle of 90 degrees or more in the first direction Z1. The multiple slits, namely the first slit 41B and the second slit 42B, each open further as the lock tab 7A is inserted into the through hole 20B.

[0107] 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. The lid 6B is locked when a portion of the lock tab 7B contacts the second main surface 82 of the lid 6B. Also, the first slit 41B and the second slit 42B close when a portion of the lock tab 7B contacts the second main surface 82 of the lid 6B.

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

[0109] The packaging material 2B comprises a main body 3, a lid 6B that is openable and closable on the main body 3, 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 that penetrates in a first direction Z1 from the first main surface 81 toward the second main surface 82. Looking toward the first direction Z1, the lid 6B is provided with a first cut 41B and a second cut 42B that extend away from the outline line 30B that defines the through hole 20B. The lock tab 7B has an outline shape larger than the through hole 20B of the lid 6B. When the lid 6B is closed to the main body 3 and the lock tab 7B is positioned 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 deforms and the lock tab 7B is inserted into the through hole 20B. Once 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 cut 41B and the second cut 42B in the lid 6B, when the lock tab 7A is moved in the first direction Z1 while the lock tab 7B is positioned on the first main surface 81 side of the lid 6B, the through hole 20B becomes more easily deformed. Because the through hole 20B is more easily deformed, the lock tab 7B becomes easier to insert into the through hole 20B.

[0111] The outer shape line 30B of the through hole 20B includes a second outer shape line 32B and a third outer shape line 33B that intersects the second outer shape line 32B when viewed in the direction toward the first direction Z1. The first cut 41B is provided in a direction away from the outer shape line 30B from the point where the second outer shape line 32B and the third outer shape line 33B intersect.

[0112] With this configuration, when the lock tab 7B is located 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, making it easier for the lock tab 7B to be inserted through 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 cut 41B and the second cut 42B are provided bends toward the first direction Z1.

[0114] With this configuration, when the lock 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 lock tab 7B comes into closer contact with the second main surface 82 of the through hole 20A, allowing the lid 6B to be locked more securely.

[0115] When the lid 6B is closed to the body 3, the through hole 20B of the lid 6B is located on the end of the lid 6B that is on the side of the body 3 where the lock tab 7B of the body 3 is provided, when viewed in the direction toward the first direction Z1. The lid 6B has a first fold 51. The first fold 51 is located away from the outer shape 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 be along the through hole 20B. A portion 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 located on the first main surface 81 side of the lid 6B, the through hole 20B becomes more easily deformed when the lock tab 7B is moved in the first direction Z1, making it easier for the lock tab 7B to be inserted into the through hole 20B.

[0117] A portion of the lid 6B can be bent at an angle of 90 degrees or less in the first direction Z1 along the first fold 51.

[0118] With this configuration, when 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. Because the lock tab 7B becomes less likely to come out of the through hole 20B, the lid 6B can be kept in a locked state.

[0119] The first fold 51 is located 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 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 is more likely to deform than the external shape of the lock tab 7B. Because the through hole 20B is more likely to deform than the external shape of the lock tab 7B, the lock tab 7B is more easily 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 outer shape line 30B of the through hole 20B of the lid 6B, and a second end 46 on the opposite side of 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 portion of the lid 6B bends in the first direction Z1 along the first fold 51, deforming so that the through hole 20B becomes larger. The enlargement of the through hole 20B makes it easier to insert the lock tab 7B 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 located away from the outer shape line 30B of the through hole 20B. The second fold 52 intersects the first cut 41B and the outer shape line 30B at the end of the lid 6B located on the side of the body 3 where the lock tab 7B is provided. The third fold 53 intersects the second cut 42B and the outer shape line 30B at the end of the lid 6B located on the side of the body 3 where the lock tab 7B is provided. A portion of the lid 6B is bendable 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 located 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, making it easier for the lock tab 7B to be inserted through the through hole 20B.

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

[0126] Although it has been explained that the lid 6B may have multiple cuts, namely the first cut 41B and the second cut 42B, this is not limited to this. For example, the lid 6B may have only one cut, for example, the first cut 41B.

[0127] Although it was explained that the inside of the packaging material 2B is not visible from the multiple cuts when viewed in the direction toward the first direction Z1, the inside of the packaging material 2B may be visible from the multiple cuts when viewed in the direction toward the first direction Z1. Also, when the lock tab 7B is not inserted into the through hole 20B, the inside of the packaging material 2B may not be visible from the multiple cuts when viewed in the direction toward the first direction Z1. When the lock tab 7B is inserted into the through hole 20B, the inside of the packaging material 2B may no longer be visible from the multiple cuts when viewed in the direction toward the first direction Z1.

[0128] Although it was explained that the lid 6B has multiple folds, the lid 6B does not have to have multiple folds. For example, the lid 6B does not have to have a first fold 51, a second fold 52, and a third fold 53.

[0129] Although it has been explained that the lid 6B has a first fold 51, a second fold 52, and a third fold 53, it is not limited to this. For example, the lid 6B does not have to have a second fold 52 and a third fold 53.

[0130] Although it was explained that 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, this is not limited to this. For example, the length of the second outline line 32B in the X direction may be larger than the length of the first outline line 31B in the X direction.

[0131] Although it has been explained 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 limited to this. For example, a portion of 6B may be bent at an angle greater 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 was explained that 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 does not necessarily have to be aligned with the through hole 20B.

[0133] Although it was explained that the first fold 51 is approximately parallel to the second outline line 32B, the first fold 51 does not necessarily have to be approximately parallel to the second outline line 32B.

[0134] It should be noted that the first cut 41B is opened by the bending of the first fold 51 and the second fold 52 in the first direction Z1, but this is not the only way. For example, the first cut 41B may open even when the first fold 51 and the second fold 52 are not bent in the first direction Z1.

[0135] It should be noted that the second cut 42B is opened by the bending of the first fold 51 and the third fold 53 in the first direction Z1, but this is not the only way. For example, the second cut 42B may be open even when the first fold 51 and the third fold 53 are not bent in the first direction Z1.

[0136] <Example 1> Figure 10 is a perspective view of packaging material 2C of modified example 1.

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

[0138] When the lid 6B 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 6B, the lock tab 7A and the through hole 20B deform when the lock tab 7A moves in the first direction Z1.

[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 deforms, making it easier to insert the lock tab 7A into the through hole 20B.

[0140] <Modification 2> Figure 11 is a plan view of packaging material 2D of modified example 2.

[0141] Modification 2 differs from Embodiment 1 in that the lock tab 7C of the packaging material 2D has a protrusion 62.

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

[0143] Because the lock tab 7C has a projection 62, the lid 6A is locked more securely by the lock tab 7C.

[0144] <Variation 3> Figure 12 is a plan view of the lid 6C of the packaging material in modified example 3.

[0145] Modification 3 differs from Embodiment 1 in that multiple slits 43 are provided in the lid 6A of the packaging material.

[0146] As shown in Figure 12, when viewed in the direction toward the first direction Z1, the lid 6A has multiple cuts 43 that extend away from the second outer shape line 32A from the outer shape line 30A that defines the through hole 20A. The multiple cuts 43 are spaced apart along the second outer shape line 32A.

[0147] With this configuration, when the lock tab 7A is inserted into the through hole 20A, both the lock tab 7A and the through hole 20A deform, making it easier for the lock tab 7A to be inserted into the through hole 20A.

[0148] <Modification 4> Figure 13 is a plan view of packaging material 2E of modified example 4.

[0149] Modification 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 the inside of the packaging material 2E is visible when viewing the multiple cuts in the direction toward the first direction Z1.

[0150] As shown in Figure 13, the lid 6E has a first cut 41E and a second cut 42E. The inside of the packaging material is visible when the first cut 41E and the second cut 42E are viewed in the direction toward the first direction Z1. The first cut 41E and the second cut 42E each have 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 on the opposite side of the first end 45.

[0151] The first cut 41E has a width in a direction intersecting the 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 the 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 the 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 the direction from the first end 45 to the second end 46 of the first cut 41E.

[0152] The second cut 42E has a width in a direction intersecting the direction from the first end 45 to the second end 46 of the second cut 42E. For example, the second cut 42E has a width of 0.5 mm to 10 mm in a direction intersecting the direction from the first end 45 to the second end 46 of the second cut 42E. Preferably, the second cut 42E has a width of 0.8 mm to 6.0 mm in a direction intersecting the direction from the first end 45 to the second end 46 of the second cut 42E. More preferably, the second cut 42E has a width of 1.0 mm to 3.0 mm in a direction intersecting the direction from the first end 45 to the second end 46 of the second cut 42E.

[0153] When the lock tab 7B is positioned on the first main surface 81 side of the lid 6E, if the lock tab 7B moves in the first direction Z1, a part of the lid 6E deforms. For example, in each of the first cut 41E and the second cut 42E, a part of the lid 6E deforms in a direction in which the width of the lid widens in a direction that intersects with the direction from the first end 45 to the second end 46 of each of the first cut 41E and the second cut 42E.

[0154] The first cut 41E and the second cut 42E each have widths in a direction intersecting the direction from the first end 45 to the second end 46 of the first cut 41E, thereby making a portion of the lid 6E less likely to tear when the lock tab 7B is inserted into the through hole 20B.
