Mode for Carrying Out the Invention

[0011] (Background Leading to the Present Disclosure) Patent Document 1 discloses a packing box including a box body, a plurality of partition plates, and cushioning blocks. In the packing box described in Patent Document 1, the user adjusts the space for storing an object by changing the arrangement of a plurality of partition plates and cushioning blocks, etc. for each object to be packed having different dimensions.

[0012] However, the plurality of partition plates and cushioning blocks are separate members. When storing objects having different dimensions inside the box body, the user changes the combination of the plurality of partition plates and the positions of the cushioning blocks for each dimension of the object. For this reason, there is a problem that the space for storing the object cannot be easily adjusted.

[0013] Therefore, the present inventors have studied a cushioning material capable of easily adjusting the space for storing an object and a blank sheet capable of assembling the cushioning material in order to solve the above-described problems, and have arrived at the present disclosure.

[0029] As shown in Figure 5, the first adjustment portion 21A is formed from a part of the base portion 4A and a part of the first side wall portion 5A. The first adjustment portion 21A is deformable into a first state and a second state. The first state is when the first adjustment portion 21A is not bent at a position away from the first side wall portion 5A in a third direction X1 from the first end to the second end. The second state is when the first adjustment portion 21A is bent from the base portion 4A in a first direction Z1.

[0030] As shown in Figure 5, in the second state, the first adjustment section 21A is formed by a first section 31 in which a part of the base section 4A is bent in a first direction Z1, and a second section 32 in which a part of the first side wall section 5A is bent in a third direction X1. The first section 31 and the second section 32 are connected.

[0031] When the first adjustment section 21A is in the second state, the first portion 31 of the first adjustment section 21A is bent at a 90-degree angle from the base 4A in the first direction Z1. When the first adjustment section 21A is in the second state, the second portion 32 of the first adjustment section 21A is bent at a 90-degree angle from the first side wall portion 5A in the third direction X1. When the first adjustment section 21A is in the second state, when viewed from the fifth direction Y1 along the first side wall portion 5A, the first adjustment section 21A has an inverted L-shape.

[0032] When the first adjustment section 21A is in the second state, the length H3 of the first adjustment section 21A in the first direction Z1 is smaller than the length H1 of the first side wall section 5A in the first direction Z1. When the first adjustment section 21A is in the second state, the length L12 of the first adjustment section 21A in the fifth direction Y1 is longer than the length L2 of the first adjustment section 21A in the third direction X1. The length H3 of the first adjustment section 21A in the first direction Z1 is relatively the same length as the length L2 of the first adjustment section 21A in the third direction X1.

[0033] As shown in Figure 2, the second adjustment section 22A is formed from a part of the base 4A and a part of the second side wall 6A. The second adjustment section 22A has the same configuration as the first adjustment section 21A. The difference between the second adjustment section 22A and the first adjustment section 21A is that the position in which it is located is different, and that it is formed from a part of the base 4A and a part of the second side wall 6A.

[0034] As shown in Figures 2 and 3, the second adjustment section 22A is deformable into a third state and a fourth state. The third state is when the second adjustment section 22A is not bent and is located away from the second side wall section 6A in the fourth direction X2, opposite to the third direction X1. The fourth state is when the second adjustment section 22A is bent from the base section 4A in the first direction Z1 and is located away from the second side wall section 6A in the fourth direction X2.

[0035] In the fourth state, the second adjustment section 22A is formed by a third section 33, which is a part of the base section 4A bent in the first direction Z1, and a fourth section 34, which is a part of the second side wall section 6A bent in the fourth direction X2. The third section 33 and the fourth section 34 are connected. When the second adjustment section 22A is in the fourth state, the third section 33 is bent at a 90-degree angle from the base section 4A in the first direction Z1, and the fourth section 34 is bent at a 90-degree angle from the second side wall section 6A in the fourth direction X2.

The third space S3 is larger than the second space S2 by a length L3 in the fourth direction X2 of the second adjustment section 22A.

[0040] Multiple third adjustment sections 23A adjust the space inside the buffer material 2A in the fifth direction Y1 and the sixth direction Y2. The third adjustment sections 23A have the same configuration as the first adjustment section 21A. The differences between the third adjustment sections 23A and the first adjustment section 21A are that they are positioned differently and are formed from a part of the base 4A and a part of the third side wall 7A.

[0041] As shown in Figure 4, the multiple third adjustment parts 23A are arranged at intervals along the third side wall portion 7A. The multiple third adjustment parts 23A are formed from a part of the base portion 4A and a part of the third side wall portion 7A. Each of the multiple third adjustment parts 23A is deformable into a fifth state and a sixth state. The fifth state is a state in which the multiple third adjustment parts 23A are not bent at a position away from the third side wall portion 7A in the fifth direction Y1 toward the third end to the fourth end of the base portion 4A. The sixth state is a state in which the multiple third adjustment parts 23A are bent from the base portion 4A in the first direction Z1 at a position away from the third side wall portion 7A in the fifth direction Y1.

[0042] As shown in Figure 6, in the sixth state, the third adjustment section 23A is formed by a fifth section 35, which is a part of the base section 4A bent in the first direction Z1, and a sixth section 36, which is a part of the third side wall section 7A bent in the fifth direction Y1. The fifth section 35 and the sixth section 36 are connected. In the sixth state, the fifth section 35 is bent at a 90-degree angle from the base section 4A in the first direction Z1, and the sixth section 36 is bent at a 90-degree angle from the third side wall section 7A in the fifth direction Y1. When the third adjustment section 23A is in the sixth state, when viewed from the third direction X1 along the third side wall section 7A, the third adjustment section 23A has an inverted L-shape.

[0043] The third adjustment section 23A has the same configuration as the first adjustment section 21A, but the third adjustment section 23A is smaller than the first adjustment section 21A. As shown in Figure 6, when the third adjustment section 23A is in the sixth state, the length H4 of the third adjustment section 23A in the first direction Z1 is shorter than the length H2 of the third side wall section 7A.

[0044] When the third adjustment section 23A is in the fifth state, a fourth space S4 is defined between the third side wall 7A and the fourth side wall 8A on the first main surface 81 of the base 4A. The fourth space S4 has a length from the third inner wall 53 to the fourth inner wall 54 in the fifth direction Y1.

[0045] When the third adjustment section 23A is in the sixth state, a fifth space S5 smaller than the fourth space S4 is defined between the fourth side wall section 8A and the third adjustment section 23A on the first main surface 81 of the base section 4A. The fifth space S5 is smaller than the fourth space S4 by a length L13 in the fifth direction Y1 of the multiple third adjustment sections 23A.

[0046] The fourth adjustment section 24A adjusts the space inside the cushioning material 2A in the fifth direction Y1 and the sixth direction Y2. The fourth adjustment section 24A is formed from a part of the base 4A. The fourth adjustment section 24A is deformable into a seventh state and an eighth state. The seventh state is when the fourth adjustment section 24A is not bent at a position away from the third side wall 7A in the fifth direction Y1. The eighth state is when the fourth adjustment section 24A is bent in the first direction Z1 at a position away from the third side wall 7A in the fifth direction Y1. As shown in Figure 7, in the eighth state, the fourth adjustment section 24A is bent at a 90-degree angle from the base 4A in the first direction Z1. When the fourth adjustment section 24A is in the eighth state, it has an inverted L-shape when viewed from the fourth direction X2. The fourth adjustment section 24A has an insertion piece 75. The fourth adjustment section 24A is inserted into the through hole 71 of the lid 10A when it is in the eighth state. When the fourth adjustment section 24A is in the eighth state and the lid 10A is closed, a part of the fourth adjustment section 24A is inserted into the through hole 71. When the fourth adjustment section 24A is in the eighth state and the lid 10A is closed, the insertion piece 75 of the fourth adjustment section 24A is inserted into the through hole 71.

[0047] When the fourth adjustment section 24A is in the eighth state, a sixth space S6 smaller than the fourth space S4 is defined between the fourth side wall section 8A and the fourth adjustment section 24A on the first main surface 81 of the base section 4A.

[0048] As shown in Figure 5, the first support portion 41A supports the first adjustment portion 21A when the first adjustment portion 21A is in the second state. The first support portion 41A is formed from a part of the first side wall portion 5A. The first support portion 41A is connected to the first adjustment portion 21A.

[0054] The fourth inner wall portion 54 is located inside the fourth side wall portion 8A.

[0055] The method for storing the object in the cushioning material 2A in this embodiment will now be described.

[0056] Figure 8 is a plan view of the first electronic device 91 housed in the cushioning material 2A shown in Figure 2. Figure 9 is a plan view of the second electronic device 92 housed in the cushioning material 2A shown in Figure 3. Figure 10 is a plan view of the third electronic device 93 housed in the cushioning material 2A shown in Figure 4.

[0057] In this embodiment, the object to be stored in the space inside the cushioning material 2A is an electronic device, and a method for storing the object in the cushioning material 2A is described. The electronic devices in this embodiment are the first electronic device 91, the second electronic device 92, and the third electronic device 93. As shown in Figures 8 to 10, the first electronic device 91, the second electronic device 92, and the third electronic device 93 each have a rectangular shape. For example, the first electronic device 91, the second electronic device 92, and the third electronic device 93 are each computers. The first electronic device 91, the second electronic device 92, and the third electronic device 93 are each different in size.

[0058] A method for storing an object in a cushioning material 2A includes the steps of adjusting the internal space of the cushioning material 2A and storing the object in the adjusted internal space of the cushioning material 2A.

[0059] The following describes the steps for adjusting the internal space of cushioning material 2A.

[0060] The internal space of the cushioning material 2A can be adjusted to accommodate the first electronic device 91, the second electronic device 92, or the third electronic device 93. The internal space of the cushioning material 2A can be adjusted by the first adjustment section 21A, the second adjustment section 22A, the third adjustment section 23A, and the fourth adjustment section 24A, respectively, to accommodate the first electronic device 91, the second electronic device 92, or the third electronic device 93. The internal space of the cushioning material 2A can be adjusted to accommodate the dimensions of the first electronic device 91, the second electronic device 92, or the third electronic device 93.

[0061] As shown in Figure 8, the dimensions of the first space S1 are approximately the same as the dimensions of the first electronic device 91 in the third direction X1 and the fourth direction X2. The dimensions of the fourth space S4 are approximately the same as the dimensions of the first electronic device 91 in the fifth direction Y1 and the sixth direction Y2. "Approximately" means that the error includes an error of 5% to 10%, and the space inside the cushioning material 2A is larger.

[0062] In order to house the first electronic device 91 in the cushioning material 2A, the internal space of the cushioning material 2A can be adjusted to a first space S1 and a fourth space S4. The internal space of the cushioning material 2A can be adjusted to a first space S1 by setting the first adjustment part 21A to a first state and the second adjustment part 22A to a third state. The internal space of the cushioning material 2A can be adjusted to a fourth space S4 by setting the third adjustment part 23A to a fifth state and the fourth adjustment part 24A to a seventh state. In other words, by not bending the first adjustment part 21A, the second adjustment part 22A, the third adjustment part 23A and the fourth adjustment part 24A in the first direction Z1, the internal space of the cushioning material 2A can be adjusted to a first space S1 and a fourth space S4.

[0063] As shown in Figures 8 and 9, the second electronic device 92 differs from the first electronic device 91 in the lengths of the third direction X1 and the fourth direction X2, and the lengths of the fifth direction Y1 and the sixth direction Y2. The lengths of the third direction X1 and the fourth direction X2, and the lengths of the fifth direction Y1 and the sixth direction Y2 of the second electronic device 92 are smaller than the lengths of the third direction X1 and the fourth direction X2, and the lengths of the fifth direction Y1 and the sixth direction Y2 of the first electronic device 91.

[0064] As shown in Figure 9, the dimensions of the second space S2 are approximately the same as the dimensions of the second electronic device 92 in the third direction X1 and the fourth direction X2. The dimensions of the sixth space S6 are approximately the same as the dimensions of the second electronic device 92 in the fifth direction Y1 and the sixth direction Y2.

[0065] In order to house the second electronic device 92 in the cushioning material 2A, the internal space of the cushioning material 2A can be adjusted to form a second space S2 and a sixth space S6.

[0066] The internal space of the cushioning material 2A can be adjusted from the first space S1 to the second space S2 by the first adjustment part 21A and the second adjustment part 22A. The internal space of the cushioning material 2A can be adjusted from the first space S1 to the second space S2 by deforming the first adjustment part 21A from the first state to the second state and deforming the second adjustment part 22A from the third state to the fourth state. In other words, the internal space of the cushioning material 2A can be adjusted to the second space S2 by bending the first adjustment part 21A and the second adjustment part 22A in the first direction Z1.

[0067] Furthermore, when the first adjustment unit 21A is in the second state and the second adjustment unit 22A is in the fourth state, the first adjustment unit 21A and the second adjustment unit 22A are each supported by the first support unit 41A and the second support unit 42A, respectively. By the first support unit 41A and the second support unit 42A each supporting the first adjustment unit 21A and the second adjustment unit 22A, the space inside the cushioning material 2A adjusted by the first adjustment unit 21A and the second adjustment unit 22A, i.e., the second space S2, can be maintained.

[0068] The internal space of the cushioning material 2A is adjusted from the fourth space S4 to the sixth space S6 by the fourth adjustment part 24A. The internal space of the cushioning material 2A can be adjusted from the fourth space S4 to the sixth space S6 by deforming the fourth adjustment part 24A from the seventh state to the eighth state. In other words, the internal space of the cushioning material 2A can be adjusted to the sixth space S6 by bending the fourth adjustment part 24A in the first direction Z1.

[0069] When the fourth adjustment section 24A is in the eighth state, closing the lid 10A causes the insertion piece 75 of the fourth adjustment section 24A to be inserted into the through hole 71 of the lid 10A. By inserting the insertion piece 75 into the through hole 71, the fourth adjustment section 24A can be maintained in a bent state in the first direction Z1. That is, by inserting the insertion piece 75 into the through hole 71, the space inside the cushioning material 2A adjusted by the fourth adjustment section 24A, i.e., the sixth space S6, can be maintained.

[0070] As shown in Figures 8 to 10, the length of the fifth direction Y1 and the sixth direction Y2 of the third electronic device 93 differs from that of the first electronic device 91 and the second electronic device 92. As shown in Figures 8 and 10, the lengths of the fifth direction Y1 and the sixth direction Y2 of the third electronic device 93 are smaller than the lengths of the fifth direction Y1 and the sixth direction Y2 of the first electronic device 91. As shown in Figures 9 and 10, the lengths of the fifth direction Y1 and the sixth direction Y2 of the third electronic device 93 are larger than the lengths of the fifth direction Y1 and the sixth direction Y2 of the second electronic device 92.

[0071] As shown in Figure 10, the dimensions of the first space S1 are approximately the same as the dimensions of the third electronic device 93 in the third direction X1 and the fourth direction X2. The dimensions of the fifth space S5 are approximately the same as the dimensions of the third electronic device 93 in the fifth direction Y1 and the sixth direction Y2.

[0072] In order to house the third electronic device 93 in the space inside the cushioning material 2A, the cushioning material 2A can be adjusted to form a first space S1 and a fifth space S5.

[0073] The internal space of the cushioning material 2A can be adjusted from the fourth space S4 to the fifth space S5 by the third adjustment part 23A. The internal space of the cushioning material 2A can be adjusted from the fourth space S4 to the fifth space S5 by deforming the third adjustment part 23A from the fifth state to the sixth state. In other words, by bending the third adjustment part 23A in the first direction Z1, the internal space of the cushioning material 2A can be adjusted to the fifth space S5.

[0074] Furthermore, when the third adjustment unit 23A is in the sixth state, the third adjustment unit 23A is supported by the third support unit 43A. By supporting the third adjustment unit 23A with the third support unit 43A, the space inside the cushioning material 2A adjusted by the third adjustment unit 23A, i.e., the fifth space S5, can be maintained.

[0075] After completing the step of adjusting the internal space of the cushioning material 2A, the step of storing the object in the adjusted internal space of the cushioning material 2A is performed. In the step of storing the object in the adjusted internal space of the cushioning material 2A after completing the step of adjusting the internal space of the cushioning material 2A, the first electronic device 91, the second electronic device 92, or the third electronic device 93 may be stored in the internal space of the cushioning material 2A.

[0076] The effects of the blank sheet 1A in this embodiment will be explained.

[0077] The cushioning material 2A is assembled by folding the blank sheet 1A. The cushioning material 2A assembled from the blank sheet 1A comprises a base portion 4A, a first side wall portion 5A, a second side wall portion 6A, a first adjustment portion 21A, and a first support portion 41A. The base portion 4A has a first main surface 81 and a second main surface opposite to the first main surface 81. The base portion 4A has a first end and a second end opposite to the first end. The first side wall portion 5A extends from the first end of the base portion 4A in a first direction Z1 from the second main surface toward the first main surface 81. The second side wall portion 6A extends from the second end of the base portion 4A in the first direction Z1. The first adjustment portion 21A is formed from a part of the base portion 4A. The first adjustment section 21A is located away from the first side wall 5A in a third direction X1 from the first end to the second end, and is in a first state of not bending and in the first direction Z1 It is deformable into a second state in which it is bent and into a second state. The first support portion 41A supports the first adjustment portion 21A when the first adjustment portion 21A is in the second state. When the first adjustment portion 21A is in the first state, a first space S1 is defined between the first side wall portion 5A and the second side wall portion 6A on the first main surface 81 of the base portion 4A. When the first adjustment portion 21A is in the second state, a third space S3 smaller than the first space S1 is defined between the first adjustment portion 21A and the second side wall portion 6A on the first main surface 81 of the base portion 4A.

[0078] With this configuration, the blank sheet 1A can be assembled into a cushioning material 2A that allows for easy adjustment of the space for storing objects. The cushioning material 2A can be adjusted from the first space S1 to the third space S3 by bending the first adjustment section 21A. Therefore, the cushioning material 2A can be easily adjusted by the first adjustment section 21A to accommodate objects of different sizes.

[0079] Furthermore, when the first adjustment section 21A is in the second state, the first adjustment section 21A can be maintained in a bent state in the first direction Z1 by being supported by the first support section 41A. By maintaining the first adjustment section 21A in a bent state in the first direction Z1, the third space S3 adjusted by the first adjustment section 21A can be maintained. Therefore, objects to be stored in the third space S3 can be stored with cushioning provided by the cushioning material 2A.

[0080] The cushioning material 2A assembled from the blank sheet 1A further comprises a second adjustment section 22A and a second support section 42A. The second adjustment section 22A is formed from a part of the base section 4A. The second adjustment section 22A is deformable between a third state in which it is not bent and a fourth state in which it is bent in the first direction Z1, at a position away from the second side wall section 6A in a fourth direction X2 opposite to the third direction X1. The second support section 42A supports the second adjustment section 22A when it is in the fourth state. When the first adjustment section 21A is in the second state and the second adjustment section 22A is in the third state, a second space S2 smaller than the third space S3 is defined between the first adjustment section 21A and the second adjustment section 22A on the first main surface 81 of the base section 4A.

[0081] With this configuration, the blank sheet 1A can be assembled into a cushioning material 2A that allows for easy adjustment of the space for storing objects. The cushioning material 2A can be adjusted from the first space S1 to the second space S2 by bending the first adjustment section 21A and the second adjustment section 22A. Therefore, the cushioning material 2A can be easily adjusted by the first adjustment section 21A and the second adjustment section 22A to accommodate objects of different sizes.

[0082] Furthermore, when the second adjustment section 22A is in the fourth state, the second adjustment section 22A can be maintained in a bent state in the first direction Z1 by being supported by the second support section 42A. By maintaining the second adjustment section 22A in a bent state in the first direction Z1, the space adjusted by the second adjustment section 22A can be maintained.

[0083] When there is a large difference in the size of objects of different sizes, adjusting the space inside the cushioning material 2A with the first adjustment part 21A and the second adjustment part 22A makes it possible to reduce the size of the first adjustment part 21A and the second adjustment part 22A. Because the size of the first adjustment part 21A and the second adjustment part 22A can be reduced, it becomes easier to bend the first adjustment part 21A and the second adjustment part 22A in the first direction Z1.

[0084] In the second state, the first adjustment section 21A is bent at a 90-degree angle from the base 4A.

[0085] This configuration makes it easier to store an object in the space inside the cushioning material 2A adjusted by the first adjustment unit 21A, and also makes it easier to maintain the first adjustment unit 21A in the second state.

[0086] The base portion 4A further has a third end intersecting the first end and a fourth end facing the third end. The cushioning material 2A assembled from the blank sheet 1A further comprises a third side wall portion 7A, a fourth side wall portion 8A, a third adjustment portion 23A, and a third support portion 43A. The third side wall portion 7A extends from the third end of the base portion 4A in a first direction Z1. The fourth side wall portion 8A extends from the fourth end of the base portion 4A in a first direction Z1. The third adjustment portion 23A is formed from a part of the base portion 4A. The third adjustment portion 23A is deformable between a fifth state in which it is not bent and a sixth state in which it is bent in the first direction Z1, at a position away from the third side wall portion 7A in a fifth direction Y1 toward the fourth end of the base portion 4A. When the multiple third adjustment parts 23A are in the fifth state, a fourth space S4 is defined between the third side wall 7A and the fourth side wall 8A on the first main surface 81 of the base 4A. When the multiple third adjustment parts 23A are in the sixth state, a fifth space S5 smaller than the fourth space S4 is defined between the fourth side wall 8A and the multiple third adjustment parts 23A on the first main surface 81 of the base 4A.

[0087] With this configuration, the blank sheet 1A can be assembled into a cushioning material 2A that allows for easy adjustment of the space for storing objects. By bending the third adjustment section 23A, the internal space of the cushioning material 2A can be adjusted from the fourth space S4 to the fifth space S5. Therefore, the third adjustment section 23A allows for easy adjustment of the internal space of the cushioning material 2A to accommodate objects of different sizes.

[0088] Furthermore, when the third adjustment section 23A is in the sixth state, the third adjustment section 23A can be maintained in a bent state in the first direction Z1 by being supported by the third support section 43A. By maintaining the third adjustment section 23A in a bent state in the first direction Z1, the space adjusted by the third adjustment section 23A can be maintained.

[0089] The cushioning material 2A assembled from the blank sheet 1A further comprises a first inner wall portion 51 which is located inside the first side wall portion 5A and outside the first adjustment portion 21A. The first inner wall portion 51 has a notch 55 into which the first support portion 41A can be inserted.

[0090] This configuration allows the impact from the outside of the cushioning material 2A to be mitigated inward. In other words, the first inner wall portion 51 can mitigate the impact transmitted to the object when the cushioning material 2A is subjected to an impact from the outside, while the object is placed on the first main surface 81 of the base portion 4A of the cushioning material 2A.

[0091] Furthermore, when the first support portion 41A is inserted into the notch 55 of the first inner wall portion 51, the first support portion 41A can more easily support the first adjustment portion 21A when the first adjustment portion 21A is in the second state.

[0092] A portion of the first adjustment portion 21A is formed by the first side wall portion 5A. In the second state, the first adjustment portion 21A is formed by a first portion 31 formed by bending a portion of the base portion 4A in a first direction Z1, and a second portion 32 formed by bending a portion of the first side wall portion 5A in a third direction X1.

[0093] With this configuration, the blank sheet 1A can be assembled into a cushioning material 2A that allows for easy adjustment of the space for storing the object. The first adjustment section 21A, having a first portion 31 and a second portion 32, is made more flexible. Furthermore, the first adjustment section 21A, having a first portion 31 and a second portion 32, makes it easier to maintain a bent state in the first direction Z1. In other words, the first adjustment section 21A can maintain the space inside the adjusted cushioning material 2A.

[0094] The first support portion 41A is formed from a part of the first side wall portion 5A. The first support portion 41A is connected to a plurality of first adjustment portions 21A.

[0095] With this configuration, the first support portion 41A can support the first adjustment portion 21A more stably when the first adjustment portion 21A is in the second state. And because the first adjustment portion 21A is stably supported, the first adjustment portion 21A can maintain the space inside the adjusted cushioning material 2A.

[0096] When one or more first adjustment units 21A are in the second state, the fifth direction Y along the first side wall 5A 1 As can be seen, one or more first adjustment sections 21A have an inverted L-shape.

[0097] This configuration allows the object to be more stably stored in the cushioning material 2A.

[0098] When one or more first adjustment units 21A are in the second state, the length of the first adjustment unit 21A in the fifth direction Y1 is longer than the length of the first adjustment unit 21A in the third direction X1.

[0099] Because the length of the first adjustment section 21A in the fifth direction Y1 is longer than the length of the first adjustment section 21A in the third direction X1, the first adjustment section 21A is less likely to deform in the fourth direction X2 even when subjected to a force in the fourth direction X2 by the object housed in the cushioning material 2A. Therefore, when the first adjustment section 21A is in the second state, it can maintain the second state more stably.

[0100] The cushioning material 2A assembled from the blank sheet 1A further comprises a fourth adjustment section 24A and a lid section 10A. The fourth adjustment section 24A is formed from a part of the base section 4A. The fourth adjustment section 24A is 3 Side wall 7 A to the 5 direction Y1At a distance from each other, it is deformable into a seventh state in which it is not bent and an eighth state in which it is bent in the first direction Z1. The lid 10A is openable and closable and has a through hole 71 into which the fourth adjustment part 24A is inserted when it is in the eighth state. When the fourth adjustment part 24A is in the eighth state, a sixth space S6 smaller than the first space S1 is defined between the fourth side wall 8A and the fourth adjustment part 24A on the first main surface 81 of the base 4A. When the fourth adjustment part 24A is in the eighth state and the lid 10A is closed, a part of the fourth adjustment part 24A is inserted into the through hole 71.

[0101] With this configuration, the blank sheet 1A can be assembled into a cushioning material 2A that allows for easy adjustment of the space for storing objects. By bending the fourth adjustment section 24A, the internal space of the cushioning material 2A can be adjusted from the fourth space S4 to the sixth space S6. Therefore, the fourth adjustment section 24A allows for easy adjustment of the internal space of the cushioning material 2A to accommodate objects of different sizes.

[0102] Furthermore, when the fourth adjustment section 24A is in the eighth state and the lid 10A is closed, a portion of the fourth adjustment section 24A is inserted into the through hole 71 of the lid 10A, thereby maintaining the fourth adjustment section 24A in a bent state in the first direction Z1. As a result, the object can be stored in the cushioning material 2A while maintaining the sixth space S6.

[0103] The cushioning material 2A is assembled by folding the blank sheet 1A described above.

[0104] With this configuration, the cushioning material 2A allows for easy adjustment of the space for storing the object. Furthermore, the internal space of the cushioning material 2A can be adjusted using only the blank sheet 1A. In addition, the internal space of the cushioning material 2A can be adjusted by folding it. Therefore, the use of other components to adjust the internal space of the cushioning material 2A can be minimized.

[0105] The storage method involves storing the object in the cushioning material 2A described above. The storage method includes the steps of adjusting the internal space of the cushioning material 2A and storing the object in the adjusted internal space of the cushioning material 2A. In the step of adjusting the internal space of the cushioning material 2A, the internal space of the cushioning material 2A is adjusted by deforming the first adjustment part 21A to a first state or a second state.

[0106] By placing an object inside the cushioning material 2A, the object can mitigate impacts from outside the cushioning material 2A. For example, by placing an electronic device inside the cushioning material 2A, the electronic device can mitigate impacts from outside the cushioning material 2A.

[0107] Furthermore, this storage method allows multiple objects of different sizes to be stored in the internal space of the cushioning material 2A, each of which is adjusted to fit its respective size. By being stored in the internal space of the adjusted cushioning material 2A, each of the multiple objects of different sizes can absorb impacts received from the outside of the cushioning material 2A.

[0108] For example, the object is an electronic device, and the multiple electronic devices are a first electronic device 91, a second electronic device 92, or a third electronic device 93. The first electronic device 91, the second electronic device 92, and the third electronic device 93 are each of different sizes. The internal space of the cushioning material 2A can be adjusted to accommodate the first electronic device 91, the second electronic device 92, or the third electronic device 93. By housing the first electronic device 91, the second electronic device 92, or the third electronic device 93 in the internal space of the cushioning material 2A adjusted for each of them, the impact that the first electronic device 91, the second electronic device 92, or the third electronic device 93 receives from the outside of the cushioning material 2A can be mitigated.

[0109] In this embodiment, the object is described as an electronic device, but the object does not have to be an electronic device.

[0110] Although it was explained that blank sheet 1A is made of corrugated cardboard, this is not the only option. For example, blank sheet 1A may be made of cardboard, film, or other materials.

[0111] Although it has been stated that the blank sheet 1A includes a third side wall portion 7A, a fourth side wall portion 8A, a lid portion 10A, a second adjustment portion 22A, a third adjustment portion 23A, a fourth adjustment portion 24A, a second support portion 42A, and a third support portion 43A, it is not limited to this. For example, the blank sheet 1A does not need to include a third side wall portion 7A, a fourth side wall portion 8A, a lid portion 10A, a second adjustment portion 22A, a third adjustment portion 23A, a fourth adjustment portion 24A, a second support portion 42A, and a third support portion 43A.

[0112] Although it was explained that the base 4A is rectangular when viewed from the second direction Z2, the base 4A does not have to be rectangular when viewed from the second direction Z2.

[0113] Although it has been explained that the first side wall portion 5A has a rectangular shape when viewed from the third direction X1, the first side wall portion 5A does not have to be rectangular when viewed from the third direction X1.

[0114] Although it has been explained that the second side wall portion 6A has a rectangular shape when viewed from the fourth direction X2, the second side wall portion 6A does not have to be rectangular when viewed from the fourth direction X2.

[0115] Although it was explained that the lid portion 10A is connected to the third side wall portion 7A, this is not limited to that. For example, the lid portion 10A may be connected to the fourth side wall portion 8A.

[0116] Although it has been explained that the first adjustment section 21A, the second adjustment section 22A, the third adjustment section 23A, and the fourth adjustment section 24A are bent at a 90-degree angle from the base 4A in the first direction Z1, this is not limited to this. For example, the first adjustment section 21A, the second adjustment section 22A, the third adjustment section 23A, and the fourth adjustment section 24A may be bent at an angle of 80 degrees or more and 100 degrees or less from the base 4A.

[0117] Although it has been explained that the second portion 32 of the first adjustment section 21A is bent at a 90-degree angle from the first side wall 5A in the third direction X1, this is not limited to this. For example, the second portion 32 of the first adjustment section 21A may be bent at an angle of 80 degrees or more and 100 degrees or less from the first side wall 5A in the third direction X1.

[0118] Although it has been explained that the third portion 33 of the second adjustment section 22A is bent at a 90-degree angle in the fourth direction X2 from the second side wall 6A, this is not limited to this. For example, the third portion 33 of the second adjustment section 22A may be bent at an angle of 80 degrees or more and 100 degrees or less in the fourth direction X2 from the second side wall 6A.

[0119] Although it has been explained that the fifth portion 35 of the third adjustment section 23A is bent at a 90-degree angle from the third side wall 7A in the fifth direction Y1, this is not limited to this. For example, the fifth portion 35 of the third adjustment section 23A may be bent at an angle of 80 degrees or more and 100 degrees or less from the third side wall 7A in the fifth direction Y1.

[0120] In addition, while an example has been described in which the fourth adjustment section 24A can be deformed into a seventh state in which it is not bent and an eighth state in which it is bent in the first direction Z1, at a position away from the third side wall section 7A in the fifth direction Y1, the explanation is not limited to this. For example, the fourth adjustment section 24A may be deformed into a state in which it is not bent and a state in which it is bent in the first direction Z1, at a position away from the first side wall section 5A in the third direction X1.

[0121] Although it has been explained that the fourth adjustment unit 24A adjusts the internal space of the cushioning material 2A in the fifth direction Y1 and the sixth direction Y2, it is not limited to this. For example, the fourth adjustment unit 24A may adjust the internal space of the cushioning material 2A in the third direction X1 and the fourth direction X2.

[0122] Although Figure 1 shows an example where the blank sheet 1A has one first adjustment section 21A and one second adjustment section 22A, the blank sheet 1A may have multiple first adjustment sections 21A and multiple second adjustment sections 22A.

[0123] Although an example has been described in which the blank sheet 1A has multiple third adjustment sections 23A, the blank sheet 1A may have only one third adjustment section 23A.

[0124] Although Figure 1 shows an example in which the blank sheet 1A has one first support portion 41A and one second support portion 42A, the blank sheet 1A may have multiple first support portions 41A and multiple second support portions 42A.

[0125] Although it has been explained that the blank sheet 1A has one fourth adjustment section 24A and the lid section 10A has one through hole 71, this is not limited to this configuration. For example, the blank sheet 1A may have multiple fourth adjustment sections 24A, and the lid section 10A may have multiple through holes 71.

[0126] Although it has been explained that each of the one first adjustment section 21A, one second adjustment section 22A, and one third adjustment section 23A can be supported by each of the one first support section 41A, one second support section 42A, and one third support section 43A, this is not limited to this. For example, each of the one first adjustment section 21A, one second adjustment section 22A, and one third adjustment section 23A may be supported by each of the multiple first support sections 41A, multiple second support sections 42A, and multiple third support sections 43A.

[0127] (Embodiment 2) Figure 11 is a plan view of an example of a blank sheet 1B according to Embodiment 2. Figures 12 and 13 are perspective views of a cushioning material 2B assembled by folding the blank sheet 1B shown in Figure 11.

[0128] Embodiment 2 describes a configuration that differs from that of Embodiment 1.

[0129] Embodiment 2 differs from Embodiment 1 in that the first adjustment portion 21B is not formed from a part of the first side wall portion 5B, and the second adjustment portion 22B is not formed from a part of the second side wall portion 6B. Also, Embodiment 2 differs from Embodiment 1 in that one first adjustment portion 21B is supported by a plurality of first support portions 41B, and the first support portion 41B is formed from a part of the base portion 4B.

[0130] (Blank sheet) The blank sheet 1B shown in Figure 11 is folded to assemble the cushioning material 2B shown in Figures 12 and 13. The blank sheet 1B is folded along the fold line 61 or cut line 65 to assemble the cushioning material 2B.

[0131] (buffer material) As shown in Figures 12 and 13, the cushioning material 2B comprises a first adjustment section 21B, a second adjustment section 22B, a plurality of first support sections 41B, and a plurality of second support sections 42B.

[0132] The first adjustment section 21B and the second adjustment section 22B are each formed from a part of the base section 4B. As shown in Figures 12 and 13, the first adjustment section 21B and the second adjustment section 22B are formed from the base section 4B in the first direction Z1 It bends.

[0133] Multiple first support portions 41B support one first adjustment portion 21B. Multiple first support portions 41B are formed from a part of the base portion 4B. Multiple first support portions 41B are connected to the first adjustment portion 21B. Each of the multiple first support portions 41B is connected to each of the ends of the first adjustment portion 21B. When the first adjustment portion 21B is in the second state, the multiple first support portions 41B are bent in a positional relationship from the base portion 4B in a first direction Z1 and are in contact with the first side wall portion 5B. When the first adjustment portion 21B is in the second state, the multiple first support portions 41B are bent in a positional relationship from the base portion 4B in a first direction Z1 via the first adjustment portion 21B and are in contact with the first side wall portion 5B. When the first adjustment portion 21B is in the second state, the multiple first support portions 41B are inserted into notches 55 provided in the first inner wall portion 51. When the first adjustment unit 21B is in the second state, the plurality of first support units 41B are separated from the first adjustment unit 21B. 3 direction X1 It is bent in the opposite fourth direction X2. When the first adjustment part 21B is in the second state, the multiple first support parts 41B are bent at a 90-degree angle from the first adjustment part 21B in the fourth direction X2.

[0134] First adjustment section 21 B When this is the second state, when viewed from the fifth direction Y1 along the first side wall 5B, the multiple first support portions 41B are inclined toward the first side wall 5B in a direction toward the base portion 4B.

[0135] Multiple second support portions 42B support one second adjustment portion 22B. Multiple second support portions 42B are formed from a part of the base portion 4B. Multiple second support portions 42B are connected to the second adjustment portion 22B. Each of the multiple second support portions 42B is connected to each of the ends of the second adjustment portion 22B. When the second adjustment portion 22B is in the fourth state, the multiple second support portions 42B are bent in a positional relationship from the base portion 4B in a first direction Z1 and are in contact with the second side wall portion 6B. When the second adjustment portion 22B is in the fourth state, the multiple second support portions 42B are bent in a positional relationship from the base portion 4B in a first direction Z1 via the second adjustment portion 22B The person in chargeIt is present and in contact with the second side wall portion 6B. When the second adjustment portion 22B is in the fourth state, the plurality of second support portions 42B are inserted into the notches 55 provided in the second inner wall portion 52. When the second adjustment portion 22B is in the fourth state, the plurality of second support portions 42B are bent in the third direction X1. When the second adjustment portion 22B is in the fourth state, the plurality of second support portions 42B are bent at a 90-degree angle from the second adjustment portion 22B in the third direction X1.

[0136] When the second adjustment section 22B is in the fourth state, when viewed from the fifth direction Y1, the multiple second support sections 42B are inclined toward the second side wall section 6B, in a direction that approaches the base section 4B.

[0137] Although Figures 12 and 13 show that the first inner wall portion 51 and the second inner wall portion 52 each have one notch 55, the design is not limited to this. For example, the first inner wall portion 51 and the second inner wall portion 52 may each have multiple notches 55. Each of the multiple notches 55 may be into which each of the multiple first support portions 41B or each of the multiple second support portions 42B can be inserted.

[0138] The effect of the blank sheet 1B in Embodiment 2 will be explained.

[0139] The blank sheet 1B is folded to assemble the cushioning material 2B. The cushioning material 2B assembled from the blank sheet 1B comprises a base 4B, a first side wall portion 5B, a second side wall portion 6B, a first adjustment portion 21B, and a plurality of first support portions 41B. The base 4B has a first main surface 81 and a second main surface opposite to the first main surface 81. The base 4B has a first end and a second end opposite to the first end. The first side wall portion 5B extends from the first end of the base 4B in a first direction Z1 from the second main surface toward the first main surface 81. 6BThe first adjustment portion 21B extends from the second end of the base portion 4B in a first direction Z1. The first adjustment portion 21B is formed from the base portion 4B. The first adjustment portion 21B is deformable between a first state in which it is not bent and a second state in which it is bent in the first direction Z1, at a position away from the first side wall portion 5B in a third direction X1 from the first end toward the second end. The plurality of first support portions 41B support the first adjustment portion 21B when it is in the second state. The plurality of first support portions 41B are formed from a part of the base portion 4B. When the first adjustment portion 21B is in the second state, the plurality of first support portions 41B have a positional relationship in which they are bent from the base portion 4B in a first direction Z1 and are in contact with the first side wall portion 5B. When the first adjustment section 21B is in the first state, a first space S1 is defined between the first side wall 5B and the second side wall 6B on the first main surface 81 of the base 4B. When the first adjustment section 21B is in the second state, a first space S1 is defined between the first adjustment section 21B and the second side wall 6B on the first main surface 81 of the base 4B. S1 A smaller third space, S3, is defined.

[0140] With this configuration, the blank sheet 1B can be assembled into a cushioning material 2B that allows for easy adjustment of the space for storing objects. The cushioning material 2B can be adjusted from the first space S1 to the third space S3 by bending the first adjustment section 21B. Therefore, the cushioning material 2B can be easily adjusted by the first adjustment section 21B to accommodate objects of different sizes.

[0141] Furthermore, when the first adjustment unit 21B is in the second state, the multiple first support units 41B are in the first side wall unit 5 B By making contact with it, the first adjustment unit 21B can be maintained in the second state.

[0142] The first adjustment section 21B is connected to a plurality of first support sections 41B. When the first adjustment section 21B is in the second state, the plurality of first support sections 41B are bent in a positional relationship from the base section 4B in a first direction Z1 via the first adjustment section 21B. When one or more of the first adjustment sections 21B are in the second state, the plurality of first support sections 41B are bent in a fourth direction X2 opposite to the third direction X1 from the first adjustment section 21B.

[0143] With this configuration, the blank sheet 1B can be assembled with a cushioning material 2B that allows for easy adjustment of the space for storing the object. The connection between the first adjustment section 21B and the multiple first support sections 41B allows the first adjustment section 21B and the first support sections 41B to bend simultaneously. Furthermore, the connection between the first adjustment section 21B and the multiple first support sections 41B allows the first support sections 41B to provide better support to the first adjustment section 21B.

[0144] The cushioning material 2B assembled from the blank sheet 1B further comprises a first inner wall portion 51. The first inner wall portion 51 is located inside the first side wall portion 5B and outside the first adjustment portion 21B. When the first adjustment portion 21B is in the second state, notches 55 into which a plurality of first support portions 41B are inserted are provided in the first inner wall portion 51.

[0145] When the first adjustment section 21B is in the second state, the multiple first support sections 41B are inserted into the notches 55 of the first inner wall section 51, thereby maintaining the first adjustment section 21B in a bent state in the first direction Z1.

[0146] When the first adjustment section 21B is in the second state, when viewed from the fifth direction Y1 along the first side wall section 5B, the multiple first support sections 41B are inclined toward the first side wall section 5B in a direction toward the base section 4B.

[0147] With this configuration, when the first adjustment section 21B is in the second state, the multiple first support sections 41B can be easily inserted into the notches 55 of the first inner wall section 51, and the multiple first support sections 41B can be maintained in a state where the first adjustment section 21B is bent in the first direction Z1.

[0148] Although an example has been described in which the cushioning material 2B comprises one first adjustment section 21B and one second adjustment section 22B, the cushioning material 2B may also comprise multiple first adjustment sections 21B and multiple second adjustment sections 22B.

[0149] Although an example has been described in which the cushioning material 2B has multiple first support parts 41B for one first adjustment part 21B, the cushioning material 2B may also have multiple first support parts 41B for one first adjustment part 21B.

[0150] Although it has been explained that the first adjustment section 21B and the multiple first support sections 41B are connected, the first adjustment section 21B and the multiple first support sections 41B do not necessarily have to be connected. For example, the first support sections 41B may be connected to the base section 4B and bendable from the base section 4B in the first direction Z1. For example, the first support sections 41B may support the first adjustment section 21B by contacting it. B A through-hole into which a part of the first adjustment part 21B can be inserted may be provided, and the first support part 41B may be inserted into the through-hole of the first adjustment part 21B to support the first adjustment part 21B in the second state.

[0151] Although an example has been described in which one notch 55 is provided in the first inner wall portion 51, the invention is not limited to this. For example, multiple notches 55 may be provided in the first inner wall portion 51. The number of notches 55 may be the same as the number of first support portions 41B.

[0152] Furthermore, when the first adjustment section 21B is in the second state, the multiple first support sections 41B may be bent in the first direction Z1 from the base section 4B. For example, the first support sections 41B may be bent in the first direction Z1 from the base section 4B at an angle of 80 degrees or more and 110 degrees or less.

[0153] It has been explained that when the first adjustment section 21B is in the second state, the multiple first support sections 41B are bent at a 90-degree angle from the first adjustment section 21B in the fourth direction X2, but this is not limited to this. For example, when the first adjustment section 21B is in the second state, the multiple first support sections 41B are bent at an angle of 80 degrees or more and 100 degrees or less from the first adjustment section 21B in the fourth direction X2.

[0154] Furthermore, when the second adjustment section 22B is in the second state, the multiple second support sections 42B may be bent from the base section 4B in the first direction Z1. For example, the second support sections 42B may be bent from the base section 4B at an angle of 90 degrees or more and 110 degrees or less in the first direction Z1.

[0155] It has been explained that when the second adjustment section 22B is in the fourth state, the multiple second support sections 42B are bent at a 90-degree angle from the second adjustment section 22B in the fourth direction X2, but this is not limited to this. For example, when the second adjustment section 22B is in the fourth state, the multiple second support sections 42B are bent at an angle of 80 degrees or more and 100 degrees or less from the second adjustment section 22B in the fourth direction X2.

[0156] <Example 1> Figure 14 is a perspective view of the cushioning material 2C assembled by folding the blank sheet of Modification Example 1.

[0157] The cushioning material 2C assembled by folding the blank sheet in Modification 1 differs from the cushioning material 2A assembled by folding the blank sheet 1A in Embodiment 1 in the number of first adjustment parts 21A, second adjustment parts 22A, and third adjustment parts 23A.

[0158] The cushioning material 2C comprises a plurality of first adjustment sections 21A, a plurality of second adjustment sections 22A, and one third adjustment section 23A.

[0159] Multiple first adjustment units 21A are arranged at intervals along the first side wall 5A. Multiple second adjustment units 22A are arranged at intervals along the second side wall 6A.

[0160] Multiple first adjustment units 21A are arranged at intervals along the first side wall 5A.

[0161] By arranging multiple first adjustment units 21A at intervals along the first side wall 5A, impacts from the outside of the cushioning material 2C can be further mitigated.

[0162] <Modification 2> Figure 15 is an enlarged schematic cross-sectional view of the cushioning material 2D assembled by folding the blank sheet of Modification Example 2.

[0163] As shown in Figure 15, the cushioning material 2D differs from the cushioning material 2A of Embodiment 1 in that the first adjustment portion 21A is bent at an angle θ1 from the base portion 4A in the second state. The angle θ1 is the angle between the first main surface 81 of the base portion 4A and the first adjustment portion 21A, and is between 80 degrees and less than 90 degrees.

[0164] In the second state, the first adjustment section 21A is bent at an angle θ1, that is, between 80 and 90 degrees, which makes it easier to maintain the space for storing the object that has been adjusted by the first adjustment section 21A.

[0165] <Variation 3> Figure 16 is an enlarged schematic cross-sectional view of the cushioning material 2E assembled by folding the blank sheet of Modification Example 3. Figure 17 is an enlarged plan view of the cushioning material 2E assembled by folding the blank sheet of Modification Example 3.

[0166] As shown in Figures 16 and 17, the cushioning material 2D differs from the cushioning material 2B of Embodiment 2 in that the first adjustment part 21B is bent at an angle θ2 from the base part 4B in the second state, and the plurality of first support parts 41B are bent at an angle θ3 from the first adjustment part 21B.

[0167] As shown in Figure 16, in the second state, the first adjustment section 21B is bent at an angle θ2 from the base 4B. The angle θ2 is the angle between the first main surface 81 of the base 4B and the second adjustment section 22A, and is greater than 90 degrees and less than or equal to 100 degrees.

[0168] In the second state, the first adjustment section 21B is bent at an angle θ2, which is greater than 90 degrees and less than or equal to 100 degrees, so that the first adjustment section 21B comes into closer contact with the first side wall section 5B. This contact between the first adjustment section 21B and the first side wall section 5B makes it easier to maintain the space for storing the object that was adjusted by the first adjustment section 21A.

[0169] As shown in Figure 17, when the first adjustment section 21B is in the second state, each of the multiple first support sections 41B is bent at an angle θ3 from the first adjustment section 21B. The angle θ3 is the angle between the surface of the first adjustment section 21B facing the first side wall section 5B when the first adjustment section 21B is in the second state and each of the multiple first support sections 41B, and is greater than 90 degrees and less than or equal to 100 degrees.

[0170] In the second state, the first support portion 41B is bent at an angle θ3 from the first adjustment portion 21B, that is, greater than 90 degrees but less than or equal to 100 degrees. As a result, the first support portion 41B contacts the inner wall defining the notch 55 of the first inner wall portion 51. This contact between the first support portion 41B and the inner wall defining the notch 55 of the first inner wall portion 51 makes it easier to maintain the space for storing the object, which has been adjusted by the first adjustment portion 21A.
