Summary of Invention

Technical Problem [0004]

The following description is made by referring to by way of example the case where an object to be packed is a refrigerator. Generally, the width of a front surface of a refrigerator in the lateral direction of the refrigerator and the width of a back surface of the refrigerator in the lateral direction are smaller than the width of a side surface of the refrigerator, that is, the width of the refrigerator in a direction along the depth of the refrigerator. Therefore, the space for carrying the refrigerator is limited. For example, in the case where the carrier passes through, for example, a corridor, while carrying the

656613

KPO-3515 refrigerator, the carrier may carry the refrigerator, with the front surface or the back surface of the refrigerator located to face a floor surface of the corridor, and side surfaces of the refrigerator located to face wall surfaces of the corridor. In this case, it is possible to prevent a packing material from being brought into contact with the wall surfaces of the corridor. Furthermore, in the case where the carrier carries the refrigerator in a location where the space for carrying the refrigerator can be easily secured, the carrier may also carry the refrigerator, with a side surface of the refrigerator located to face the floor surface. In such a manner, the carrier may change the orientation of the packing material in accordance with the location.

[0005]

The packing material described in Patent Literature 1 is provided with a plurality of grips. However, the longitudinal directions of the grips are the same as each other. Therefore, when the carrier changes the orientation of the packing material, he or she holds part of the packing material that is other than the grips, such as corner portions of the packing material. If the carrier holds the corner portions of the packing material, his or her fingers may get caught between the packing material and the floor surface when the carrier places the packing material on the floor surface. In view of this point, it is conceivable as another method to further form, at the packing material, second grips whose longitudinal direction is different from the longitudinal direction of the first grips as described in Patent Literature 1, in addition to the first grips of the packing material. However, in the case where a first grip and a second grip are formed at the packing material, the smaller the distance between the first and second grips, the smaller the width of corrugated cardboard present between the first grip and the second grip. That is, in the method of forming second grips separate from first grips, there is a case where the width of part of the corrugated cardboard is small, thus reducing the strength of the packing material.

[0006]

The present invention has been made to solve the above problems, and an object of the invention is provide a packing material that can reduce a decrease in the strength of the packing material.

656613 KPO-3515 Solution to Problem [0007]

Packing material according to an embodiment of the present invention includes a plate-shaped element made of corrugated cardboard and including a first area and a second area where respective grips are allowed to be freely formed. In the plateshaped element, a first cut portion, a second cut portion, and a third cut portion are formed, the first cut portion linearly extend from a beginning point to a first end point, the second cut portion linearly extending from the beginning point to a second end point, the third cut portion linearly extending from the beginning point to a third end point. In a peripheral area of the first area, the first cut portion and the second cut portion are formed, and in a peripheral area of the second area, the first cut portion and the third cut portion are formed.

Advantageous Effects of Invention [0008]

According to the embodiment of the present invention, the first cut portion is formed in the peripheral area of the first area and the peripheral area of the second area. That is, the first area and the second area are provided opposite to each other, with the first cut portion interposed between the first and second areas. Therefore, according to the embodiment of the present invention, the decrease in the strength of the packing material can be reduced.

[0025] «Operation in Embodiment 1>

Fig. 8 is a perspective view illustrating a state in which the plate element 21 is bent at the bending portion 31. A carrier can form an opening Op1 in the plate-shaped element 6A by bending the plate element 21 at the bending portion 31. The carrier can insert his or her hand or fingers into the opening Op1 and hold the packing material 100. In such a manner, the carrier can form a grip in the packing material 100 by bending the plate element 21 at the bending portion 31. Furthermore, when the carrier carries the packing material 100, with his or her hand or fingers inserted in the opening Op1, his or her hand or fingers are in contact not only with the bending portion 31, but with the plate element 21. At this time, the plate element 21 and the grasp surface sf2 are in contact with each other. Therefore, when the carrier carries the packing material 100, with his or her hand or fingers inserted in the opening Op1, the weight of the packing material 100 is distributed on the bending portion 31 and the grasp surface sf2, that is, it is distributed on the plate-shaped element 6Aand the cushioning material 6C1.

656613 KPO-3515 [0026]

Fig. 9 is a perspective view illustrating a state in which the plate element 22 is bent at the bending portion 32. The carrier can form an opening Op2 in the plateshaped element 6A by bending the plate element 22 at the bending portion 32. The carrier can insert his or her hand or fingers in the opening Op2. In such a manner, the carrier can form a grip in the packing material 100 by bending the plate element 22 at the bending portion 32. Furthermore, when the carrier carries the packing material 100, with his or her hand or fingers inserted in the opening Op2, his or her hand or fingers are in contact not only with the bending portion 32, but with the plate element 22. At this time, the plate element 22 and the grasp surface sf 1 are in contact with each other. Therefore, when the carrier carries the packing material 100, with his or her hand or fingers inserted in the opening Op2, the weight of the packing material 100 is distributed on the bending portion 32 and the grasp surface sf 1, that is, it is distributed on the plate-shaped element 6A and the cushioning material 6C1.

[0027]

Fig. 10 is a perspective view illustrating a state in which the plate element 21 and the plate element 22 are bent. The carrier may bend the plate element 21 at the bending portion 31, and bend the plate element 22 at the bending portion 32. In the state illustrated in Fig. 10, two grips are formed at the packing material 100.

[0028]

Fig. 11 schematically illustrates a state in which a carrier hm1 and a carrier hm2 carry the packing material 100. Fig. 12 is an explanatory diagram indicating holding positions at which the carrier hm1 holds the packing material 100 in the state illustrated in Fig. 11. It should be noted that as illustrated in Fig. 11, the distance between the center of gravity of the packing material 100 and a floor surface in a height direction is H1, and the distance between the cut portion 10Aand the cut portion 10B and the floor surface in the height direction is hi. The carrier hm1 forms grips at the cut portion 10A and the cut portion 10B, and holds a lower portion of the packing material 100. In a state illustrated in Fig. 12, the opening Op1 is formed at the cut portion 10A. The carrier hm2 holds an upper portion of the packing material 100. It should be noted that

656613

KPO-3515 the frame element 6B1 is shorter than the frame element 6B2. Furthermore, the frame element 6B1 is located on a front side of the refrigerator, and the frame element 6B2 is located on a lateral side of the refrigerator. Referring to Fig. 12, the frame element 6B1 is located above the frame elements 6B2 and 6B4, and thus in the state illustrated in Fig. 12, the back surface of the refrigerator faces the floor surface. In the state illustrated in Fig. 12, it is possible to easily secure space between the frame element 6B2 and a wall Wa, and also space between the frame element 6B4 and another wall Wa.

[0029]

Furthermore, in the state illustrated in Figs. 11 and 12, the cut portions 8Aand 8B are located lower than the cut portions 10Aand 10B. Thus, even if the carrier hm1 stretches his or her hands or fingers, the hands or fingers cannot easily reach the cut portions 8Aand 8B. Therefore, in the state illustrated in Figs. 11 and 12, if the carrier hm1 holds the grips at the cut portions 8A and 8B, there is a possibility that the load on the legs and loins of the carrier hm1 will be increased. Therefore, the carrier hm1 holds the grips at the cut portions 10A and 10B.

[0030]

Fig. 13 is an explanatory diagram of holding positions different from those in Fig. 12. Referring to Fig. 13, the carrier hm1 forms grips at the cut portions 9Aand 10A, and holds a lower portion of the packing material 100. In the state illustrated in Fig. 13, the opening Op2 is formed at the cut portion 10A. Although it is not illustrated, the carrier hm2 holds an upper portion of the packing material 100 as in the state illustrated in Fig. 11. In the state illustrated in Fig. 13, a side surface of the refrigerator faces the floor surface. The openings Op1 and Op2 can be both freely formed in the plateshaped element 6A, thus enabling the carrier to hold the packing material 100 in the state illustrated in Fig. 12 or in the state illustrated in Fig. 13.

[0031]

Fig. 14 schematically illustrates a state in which the carriers hm1 and hm2 carry the packing material 100 while the carrier hm2 stands at a lower position than the carrier hm1. Fig. 15 is an explanatory diagram indicating holding positions of the

656613 KPO-3515 carrier hm1 in the state illustrated in Fig. 14. It is assumed that the state of the carriers hm1 and hm2 changes from the state illustrated in Fig. 11 to that illustrated in Fig. 14. It should be noted that as illustrated in Fig. 14, the distance between the center of gravity of the packing material 100 and the floor surface is H2 in the height direction is H2, which is greater than H1. Furthermore, the distance between the cut portions 8A and 8B and the floor surface in the height direction is h2, which is nearly equal to hi, and the distance between the cut portions 10Aand 10B and the floor surface in the height direction is h3, which is greater than hi.

[0032]

As illustrated in Fig. 14, the carrier hm2 stands on the bed of a truck. In this state, the carrier hm2 stands at a higher position than the carrier hm1. Therefore, when the carrier hm2 tries to hold the packing material 100 from the bed of the truck, while maintaining an angle Θ1 of the packing material 100 that is indicated in Fig. 11, the carrier hm2 needs to bend his or her knees. Therefore, as illustrated in Fig. 14, the carriers hm1 and hm2 raise the packing material 100, as a result of which the angle of the packing material 100 is changed from the angle Θ1 of the packing material 100 as indicated in Fig. 11 to an angle Θ2 of the packing material 100 that is smaller than the angle Θ1 of the packing material 100.

[0033]

Furthermore, since the level of the center of gravity of the packing material 100 is changed to a higher level such that the distance H1 is changed to the distance H2, the level of the cut portions 10Aand 10B is also changed to a higher level such that the distance hi is changed to h3. Therefore, when the carrier hm1 holds the grips at the cut portions 10Aand 10B, he or she must hold the packing material 100 while raising his or her upper arms upwards, thus increasing the load on the carrier. Accordingly, the carrier hm1 holds the grips at the cut portions 8A and 8B, not the grips at the cut portions 10Aand 10B. That is, when the state illustrated in Fig. 11 is changed to the state illustrated in Fig. 14, the carrier hm1 changes the part to be held by his or her hands or fingers.

[0034]

656613 KPO-3515 «Advantages of Embodiment 1>

The cut portion 11 is formed in the peripheral area of the area Rg1 and the peripheral area of the area Rg2. That is, the areas Rg1 and Rg2 are provided opposite to each other, with the cut portion 11 interposed between the areas Rg1 and Rg2. Therefore, in the packing material 100, strip-shaped corrugated cardboard is not present between the peripheral area of the area Rg1 and the peripheral area of the area Rg2. If the cut portion 11 were not interposed between the areas Rg1 and Rg2, and the areas Rg1 and Rg2 were separated from each other, strip-shaped corrugated cardboard could be present between the peripheral areas of the areas Rg1 and Rg2. It should be noted that the smaller the distance between the peripheral areas of the areas Rg1 and Rg2, the thinner the strip-shaped corrugated cardboard. If the strip-shaped cardboard is thin, the strength of the packing material is reduced. In Embodiment 1, the areas Rg1 and Rg2 are provided opposite to each other, with the cut portion 11 interposed between the areas Rg1 and Rg2, whereby such strip-shaped cardboard is not present. In such a manner, strip-shaped cardboard is not present in the packing material 100, and the decrease in the strength of the packing material 100 is thus reduced, while the packing material 100 has a grip structure that achieves the state illustrated in Fig. 12 at which the back surface of the refrigerator faces the floor surface, and a grip structure that achieves the state illustrated in Fig. 13 at which the side surface of the refrigerator faces the floor surface.

[0035]

Before grips are formed at the packing material 100, the opening Op1 is not formed in the area Rg1, nor is the opening Op2 formed in the area Rg2. Thus, before grips are formed in the packing material 100, neither insects nor dust easily enters the packing material 100.

[0036]

The cut portions 11 and 13 are perpendicular to each other at the position P2. It is therefore possible to prevent the openings Op1 and Op2 from being narrowed. The carrier can thus reliably insert his or her hands or fingers into the openings Op1 and Op2. Furthermore, the cut portions 12 and 13 are perpendicular to each other at the

656613

KPO-3515 position Ρ2. If the cut portions 12 and 13 are formed such that the angle between the cut portions 12 and 13 is obtuse, the opening area of the opening Op1 is reduced. By contrast, if the cut portions 12 and 13 are formed such that the angle between the cut portions 12 and 13 is acute, part of the plate-shaped element 6Athat is sandwiched between the cut portions 12 and 13 is narrow. As a result, the strength of the plateshaped element 6A is reduced. Since the cut portions 12 and 13 are perpendicular to each other at the position P2, it is possible to prevent the opening Op1 of the packing material 100 from being narrowed, and also reduce the decrease in the strength of the plate-shaped element 6Aof the packing material 100.

[0037]

The plate-shaped element 6A includes the bending portion 31 as a portion at which the plate element 21 is bent, and the bending portion 32 as a portion at which the plate element 22 is bent. Therefore, even if the carrier bends the plate element 21 at the bending portion 31, the plate element 21 does not come off the plate-shaped element 6A, and also, even if the carrier bends the plate element 22 at the bending portion 32, the plate element 22 does not come off the plate-shaped element 6A. It is therefore possible to prevent the plate elements 21 and 22 from dropping on the floor surface, and thus also prevent them from being scattered on the floor surface.

[0038]

Although an advantage of the cut portion 10A is described above, the same advantage as described above regarding the cut portion 10A can be obtained by the cut portion 10B, since the cut portion 10B has the same configuration as the cut portion 10A.

[0039]

The packing material 100 includes the cushioning material 6C1 where the grasp surfaces sf1 and sf2 are provided. As illustrated in Fig. 8, in the case where the carrier holds the packing material 100, with his or her hand or fingers inserted in the opening Op1, the plate element 21 and the grasp surface sf2 are in contact with each other. Therefore, in the case where the carrier holds the packing material 100, with his or her hand or fingers inserted in the opening Op1, the weight of the packing material 100 is

656613

KPO-3515 distributed on the bending portion 31 and the grasp surface sf2, that is, it is distributed on the plate-shaped element 6A and the cushioning material 6C1. If the grasp surface sf2 is not formed at the cushioning material 6C1, the weight of the packing material 100 is supported only by the bending portion 31, that is, it is supported only by the plateshaped element 6A. Thus, the plate-shaped element 6A may be torn when the carrier holds the packing material 100, although whether it is torn or not depends on the weight of an object to be packed. Furthermore, as another method, it can be conceived that a reinforcing wood having a function corresponding to that of the grasp surface sf2 is provided on the plate-shaped element 6A. However, in this method, since the reinforcing wood is provided in addition to the cushioning material 6C1, not only the manufacturing cost, but the amount of waste at the time of discarding the packing material is increased. In Embodiment 1, since the packing material 100 includes the cushioning material 6C1 where the grasp surfaces sf1 and sf2 are provided, the probability that the plate-shaped element 6A will be torn can be reduced, and the manufacturing cost and the amount of waste are not increased. It should be noted that the cushioning material 6C2 has the same configuration as the cushioning material 6C1, and can thus the same advantage as the cushioning material 6C1 described above. [0040]

As illustrated in Fig. 3, the first divided area D1 includes the areas Rg1, Rg2, and Rg3. Furthermore, the distance between the area Rg3 and the first edge portion 6A1 is greater than that between the area Rg1 and the first edge portion 6A1. The carrier can form grips at both the areas Rg1 and Rg3. In the case of carrying the packing material 100 in the state illustrated in Fig. 11, the carrier can hold the grip at the area Rg1, and in the case of carrying the packing material 100 in the state illustrated in Fig. 14, the carrier can hold the grip at the area Rg3. In such a manner, the carrier can change the grip to be held between an upper one of the grips of the packing material 100 and a lower one of the grips thereof, and the workload on the carrier holding the packing material 100 is reduced. It should be noted that although the above description refers to the advantages of the cut portions 10Aand 8A, the cut portions 10B and 8B can also obtain the same advantages as the cut portions 10A and 10B,

656613 KPO-3515 since the cut portions 10B and 8B have the same configuration as the cut portions 10A and 8A, respectively.

More specifically, the outer packing material 500 includes a first surface 500Aand a second surface 500B parallel to the first surface 500A, and the cut portions 510 are formed at the first surface 500Aand the second surface 500B. The cut portions 510 have the same configuration as the cut portion 10Aas described regarding Embodiment 1. The packing material according to Modification 2 can obtain the same advantages as that according to Embodiment 1. [0043]

Fig. 18 is a top view of a bottom case 206 provided at the packing material

656613 KPO-3515 according to Embodiment 2. Fig. 19 is a top view of a cut portion 210A. As illustrated in Fig. 18, the cut portion 210Aand a cut portion 21 OB are formed at the bottom case 206.

The area Rg2 is surrounded by the cut portions 11b and 13 and the bending portion 32. Furthermore, the plate-shaped element 6A includes a bending portion 21 b1 located in a straight line connecting the beginning point and the end point of the cut portion 11b. The bending portion 21 b1 corresponds to a fourth bending portion. Preferably, part of a plate element 21b where the bending portion 21 b1 is located should be formed, for example, thin, such that it can be easily bent. Furthermore, a folding line may be formed at the part of the plate element 21b where the bending portion 21 b1 is located.

[0047] «Operation in Embodiment 2>

Fig. 20 is a perspective view illustrating a state in which the plate element 21b is bent at the bending portion 31b. The carrier can form an opening Op21 in the plateshaped element 6A by bending the plate element 21b at the bending portion 31 b. The carrier can insert his hand or fingers into the opening Op21 and then hold the packing material. In such a manner, the carrier can form a grip at the packing material by bending the plate element 21b at the bending portion 31b.

[0048]

Fig. 21 is a perspective view illustrating a state in which the plate element 22 is bent at the bending portion 32, and the plate element 21b is bent at the bending portion 21 b1. The carrier can form in the plate-shaped element 6A, an opening Op22 whose area is larger than that of the opening Op2, by bending the plate element 22 at the bending portion 32 and further bending the plate element 21b at the bending portion 21 b1. The carrier can insert his or her hand or fingers into the opening Op22 and hold the packing material. In such a manner, the carrier can form a grip in the packing material by bending the plate element 22 at the bending portion 32 and further bending the plate element 21 b at the bending portion 21 b1.

[0049] «Advantages of Embodiment 2>

KPO-3515 to Embodiment 1 and further the following advantages. It should be noted that in the area Rg1, the bending portion 21 b1 is provided. Therefore, the carrier can increase the area of the opening through which the carrier inserts his or her hand or fingers into the plate-shaped element 6A, by bending the plate element 21b at the bending portion 21 b1, even if the carrier does not bend the plate element 21b at the bending portion 31 b. The length of the bending portion 21 b1 is smaller than that of the bending portion 31b. Therefore, the force required to bend the plate element 21b at the bending portion 21 b1 is smaller than that required to bend the plate element 21b at the bending portion 31b. Therefore, in Embodiment 2, the carrier can easily increase the area of the opening through which the carrier inserts his or her hand or fingers into the plateshaped element 6A.

[0051] «Configuration in Embodiment 3>

Fig. 22 is a top view of a bottom case 306 provided at a packing material according to Embodiment 3. Fig. 23 is a top view of a cut portion 310A. As illustrated in Fig. 22, the cut portion 310Aand a cut portion 310B are formed at the bottom case 306. The cut portions 310Aand 310B are symmetrically formed.

Unlike the cut portion 11b described regarding Embodiment 2, the cut portion 11c does not include the cut portion 11 b-1. Therefore, an end point of the cut portion 11c is located at a position P1c. Furthermore, in the area Rg1, a cut portion 15 is formed to linearly extend from a beginning point of the cut

656613

KPO-3515 portion 11c to a bending portion 31c. The cut portion 15 corresponds to a fifth cut portion. The cut portion 15 linearly extends from the position p2 to the bending portion 31c.
