The first outer surface cushioning body 3 is arranged so as to be adjacent to both the first outer surface 101 and the first corner cushioning body 2 . The second outer surface cushioning body 4 is arranged so as to be adjacent to both the second outer surface 102 and the first corner cushioning body 2 . It should be noted that FIG. 1 omits illustration of an exterior material 6, which will be described later.

The first outer surface cushioning body 3 is a member that is entirely separated from the first corner cushioning body 2 . That is, the first outer surface cushioning body 3 is a separate member from the first corner cushioning body 2 . Thereby, both members can be manufactured easily. The first outer surface cushioning body 3 may be in contact with the first corner cushioning body 2 or may have a gap between the first corner cushioning body 2 and the first corner cushioning body 2 .

The second outer surface cushioning body 4 is a member that is entirely separated from the first corner cushioning body 2 . That is, the second outer surface cushioning body 4 is a separate member from the first corner cushioning body 2 . Thereby, both members can be manufactured easily. The second outer surface cushioning body 4 may be in contact with the first corner cushioning body 2 or may have a gap between it and the first corner cushioning body 2 .

Each of the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 may be made of foamed plastic such as expanded polystyrene, for example. By providing the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4, the article 100 can be protected from impact force generated during transportation.

The article 100 , the first corner cushioning body 2 , the first outer surface cushioning body 3 , the second outer surface cushioning body 4 , and the exterior material 6 are housed inside the box 5 . Box 5 is an example of a container. The box 5 may be made of cardboard, for example. Containers in the present disclosure are not limited to those made of cardboard. The container in the present disclosure may be made of synthetic resin, wood, or metal, for example.

A first corner cushion 2 , a first outer cushion 3 and a second outer cushion 4 are located between the inner wall of the box 5 and the article 100 . In FIG. 1, illustration of other cushioning bodies arranged between the inner wall of the box 5 and the article 100 is omitted. A set of cushioning bodies similar to the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 are arranged for the corners of the article 100 other than the first corner 103. may In the following description, the package including the packaging device 1 and the article 100 will be referred to as a "product package 90".

FIG. 2 is a perspective view showing the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 in the packaging device 1 shown in FIG. As shown in FIG. 2 , the packaging device 1 includes an exterior material 6 that covers the first corner cushioning body 2 , the first outer surface cushioning body 3 , and the second outer surface cushioning body 4 . In FIG. 2, the exterior material 6 is drawn with a dashed line for the convenience of making the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 easier to see. In the illustrated example, the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 are entirely covered with one exterior material 6. As shown in FIG.

The exterior material 6 has flexibility. The exterior material 6 is in contact with the surfaces of the first corner cushioning body 2 , the first outer surface cushioning body 3 , and the second outer surface cushioning body 4 . The exterior material 6 may be, for example, a member such as a synthetic resin sheet or film. Alternatively, the exterior material 6 may be a woven fabric or non-woven fabric made of fibers, or may be a mesh-like or net-like member. The exterior material 6 may be elastic and stretchable, or may be substantially non-stretchable.

In this embodiment, the three-dimensional structure in which the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 are combined has an L-shaped curved outer shape as a whole. . The exterior material 6 may cover the entire outer surface of the three-dimensional structure. Alternatively, there may be a part of the outer surface of the three-dimensional structure that is not covered with the exterior material 6 .

The first outer surface cushioning body 3 has a contact surface 3 a that contacts the first outer surface 101 of the article 100 . In this embodiment, the contact surface 3 a contacts the first outer surface 101 via the exterior material 6 . The first outer surface damping body 3 has a plate-like outer shape whose thickness direction is the direction perpendicular to the contact surface 3a.

The second outer surface cushioning body 4 has a contact surface 4 a that contacts the second outer surface 102 of the article 100 . In the present embodiment, the contact surface 4a is in contact with the second outer surface 102 via the exterior material 6. As shown in FIG. The second outer surface cushioning body 4 has a plate-like outer shape whose thickness direction is the direction perpendicular to the contact surface 4a.

The first corner cushioning body 2 has a columnar outer shape whose axial direction is parallel to both the contact surface 3a and the contact surface 4a. In the illustrated example, the first corner cushioning body 2 has a quadrangular prism shape. The axial direction of the first corner cushioning body 2 is arranged parallel to the ridge line formed by the first corner 103 of the article 100 .

The exterior material 6 in this embodiment corresponds to a first movement preventing means for preventing the first outer surface cushioning body 3 and the second outer surface cushioning body 4 from moving away from the first corner cushioning body 2 .

A first direction 91 is a direction in which the first outer surface cushioning body 3 moves away from the first corner cushioning body 2 . The first direction 91 is perpendicular to the axial direction of the first corner cushioning body 2 and parallel to the contact surface 3a. When the first outer cushioning body 3 tries to move in the first direction 91 with respect to the first corner cushioning body 2 , the tension of the exterior material 6 prevents the movement of the first outer cushioning body 3 .

A second direction 92 is a direction in which the second outer surface cushioning body 4 moves away from the first corner cushioning body 2 . The second direction 92 is perpendicular to the axial direction of the first corner cushioning body 2 and parallel to the contact surface 4a. When the second outer cushioning body 4 attempts to move in the second direction 92 relative to the first corner cushioning body 2 , the tension of the exterior material 6 prevents the movement of the second outer cushioning body 4 .

Considering the case where the product package 90 is transported, for example, by a truck, there is a possibility that the product package 90 is dropped when being loaded onto the truck or unloaded from the truck. FIG. 1(a) shows a state immediately before the product package 90 that has fallen with the first corner 103 of the article 100 facing downward lands on the floor surface 200. FIG. FIG. 1(b) shows the state immediately after the product package 90 has landed on the floor surface 200 from the state shown in FIG. 1(a). A pressing force 10 indicated by arrows in FIG.

In the state of FIG. 1(b), it is as follows. The first corner cushioning body 2 is compressed and deformed by receiving the pressing force 10 between the first corner 103 and the floor surface 200 . The compressive deformation of the first corner cushioning body 2 can reliably absorb the impact acting on the article 100 . The first outer cushioning body 3 and the second outer cushioning body 4 are prevented from moving away from the first corner cushioning body 2 by the exterior material 6 . Therefore, the first outer cushioning body 3 and the second outer cushioning body 4 are reliably held at proper positions. As a result, the first outer surface cushioning body 3 and the second outer surface cushioning body 4 can reliably receive the pressing force 10 from the first outer surface 101 and the second outer surface 102 of the article 100, so that the impact can be reliably absorbed. can be done.

If the first corner cushioning body 2 were not there, the first corner 103 of the article 100, which continues to move downward due to the inertia of the fall, would be split between the first outer cushioning body 3 and the second outer cushioning body 4. As a result, the first outer surface damping body 3 and the second outer surface damping body 4 are pressed in the first direction 91 and the second direction 92, respectively. In contrast, in the present embodiment, the provision of the first corner cushioning body 2 allows the first corner part 103 to extend between the first outer surface cushioning body 3 and the second outer surface cushioning body 4 . It is possible to reliably suppress entering by breaking into. As a result, it is possible to reliably prevent the first outer surface damping body 3 and the second outer surface damping body 4 from being pressed in the first direction 91 and the second direction 92, respectively. The body 4 can be reliably held in the correct position.

As described above, according to the present embodiment, even if the product package 90 is dropped with the first corner 103 facing down, the first corner 103 of the article 100 can be reliably protected. can be done.

FIG. 3 is a schematic cross-sectional view of a product package 300 of a comparative example. The product package 300 differs from the product package 90 in that it includes one L-shaped cushion 400 instead of the first corner cushion 2, the first outer surface cushion 3, and the second outer surface cushion 4. . The L-shaped cushioning body 400 has an overall shape corresponding to the shape in which the first corner cushioning body 2, the first outer surface cushioning body 3, and the second outer surface cushioning body 4 are integrated. That is, the L-shaped cushioning body 400 has an L-shaped bent shape at the position of the first corner 103 of the article 100 . Although the L-shaped cushioning body 400 is covered with the exterior material 6, illustration of the exterior material 6 is omitted in FIG. FIG. 3 shows a state in which the product package 300 is dropped onto the floor 200 with the first corner 103 of the article 100 facing downward.

FIG. 3A shows the state just before the product package 300 lands on the floor surface 200. FIG. In FIG. 3(a), the dimension L1 corresponds to the length from the first corner 103 to one end of the L-shaped cushioning body 400, and the dimension L2 corresponds to the length from the first corner 103 to the L-shaped cushioning body 400. It corresponds to the length to the other end.

FIG. 3B shows the state immediately after the product package 300 has landed on the floor surface 200. FIG. In this state, a force similar to the pressing force 10 shown in FIG. As a result, a bending moment is generated in the L-shaped cushioning body 400 . The bending stress due to the bending moment is maximized at the bent portion of the L-shaped cushioning body 400 . The bending stress may cause the L-shaped cushioning body 400 to split in two. The longer the dimensions L1 and L2, the greater the bending moment and bending stress. FIG. 3(b) shows the moment when a crack 401 occurs in the bent portion of the L-shaped cushioning body 400, and the L-shaped cushioning body 400 splits into fragments 402 and 403 at the crack 401. .

When the L-shaped cushioning body 400 splits as shown in FIG. 3(b), the first corner 103 of the article 100, which continues to move downward due to the inertia of the fall, breaks between the fragments 402 and 403. Thereby, the fragments 402 and 403 are pushed in the first direction 91 and the second direction 92, respectively. For this reason, the fragment 402 and the fragment 403 try to move away from each other, and tension acts on the exterior material 6 . At this time, the pieces 402 and 403 are pressed by a strong force from the article 100 having a large kinetic energy, so that the exterior material 6 is torn, and the pieces 402 and 403 move in the first direction 91 and the second direction 92, respectively. cannot be stopped from moving. As a result, the fragments 402 and 403 move away from the first corner 103 of the article 100, as shown in FIG. 3(c).

Consider the case where the product package 300 falls to the floor surface 200 again after the state shown in FIG. 3(c). In this case, as shown in FIG. 3D, the first corner 103 of the article 100 collides with the floor surface 200, and the article 100 is damaged. Thus, it is difficult to reliably protect the article 100 with the product package 300 of the comparative example.

In contrast to this, the present embodiment provides the following effects. Since no bending moment is generated in the state shown in FIG. 1(b), it is possible to reliably prevent cracking of the cushioning body and also to reliably prevent damage to the exterior material 6. FIG. After the state shown in FIG. The first outer cushioning body 3 and the second outer cushioning body 4 return to their original positions. Therefore, even if the product package 90 falls again with the first corner 103 of the article 100 facing downward, the article 100 can be reliably protected.

It has a second end surface 2 b , a first facing surface 2 c adjacent to the first outer surface 101 of the article 100 , and a second facing surface 2 d adjacent to the second outer surface 102 of the article 100 . The first facing surface 2 c is parallel to the first outer surface 101 . The second facing surface 2 d is parallel to the second outer surface 102 .

A corner facing the first corner 103 is formed at a position where the first opposing surface 2c and the second opposing surface 2d intersect. The intersection position 2e is a position where the first opposing surface 2c and the second opposing surface 2d intersect. The corner between the first opposing surface 2c and the second opposing surface 2d may be rounded, not limited to the illustrated configuration. In that case, the intersecting position 2e is the position where the plane extending from the first facing surface 2c and the extending plane from the second facing surface 2d intersect, and is the position inside the first corner cushioning body 2. shall be

The second thickness T2 is the thickness of the first corner cushioning body 2 in the direction perpendicular to the second facing surface 2d. That is, the second thickness T2 corresponds to the distance between the second opposing surface 2d and the outer surface 2g on the opposite side.

The protruding length D1 corresponds to the distance from the intersection position 2e to the first end surface 2a. The projection length D2 corresponds to the distance from the intersection position 2e to the second end surface 2b. As in this embodiment, the first corner cushioning body 2 may have a first facing surface 2c and a second facing surface 2d.

The bending moment generated in the first corner buffer 2 when the product package 90 that has fallen with the first corner 103 of the article 100 lands on the floor surface 200 is hereinafter referred to as "buffer bending moment". called. If the projecting lengths D1 and D2 are short, the damping body bending moment is small, so it is possible to reliably prevent the first corner damping body 2 from cracking. From this point of view, the protruding length D1 is preferably equal to or less than the first thickness T1, more preferably equal to or less than 0.7 times the first thickness T1, and is equal to or less than 0.5 times the first thickness T1. More preferably: Similarly, the protruding length D2 is preferably less than or equal to the second thickness T2, more preferably less than or equal to 0.7 times the second thickness T2, and less than or equal to 0.5 times the second thickness T2. is more preferable. If the projecting lengths D1 and D2 satisfy such conditions, it is possible to reliably prevent cracks from occurring in the first corner cushioning body 2 .

In the present embodiment, the provision of the first facing surface 2c and the second facing surface 2d allows the first corner cushioning body 2 to move the first corner cushioning body 2 of the article 100 when the product package 90 lands on the floor surface 200. The one corner portion 103 can be received more reliably. Therefore, the first corner 103 of the article 100 can be protected more reliably.

In the illustrated example, the area of the opposing region corresponds to the cross-sectional area of the first outer surface cushioning body 3 taken along a plane parallel to the axial direction of the first corner cushioning body 2 and perpendicular to the contact surface 3a. A cross-sectional area obtained by cutting the thin portion 12 along a plane parallel to the opposing region is hereinafter referred to as a "thin portion cross-sectional area". In the illustrated example, the ratio of the opposing region area to the thin portion cross-sectional area can be expressed as T3:T4.

The cross-sectional area of the thin portion is preferably 1/2 or less of the area of the opposing region. That is, in the illustrated example, the thickness T4 is preferably half or less than the thickness T3. If the cross-sectional area of the thin portion is too large, the thin portion 12 may crack due to the bending moment when the product package 90 lands on the floor surface 200 . On the other hand, if the cross-sectional area of the thin portion is equal to or less than the above value, the occurrence of cracks in the thin portion 12 can be reliably prevented.

The cross-sectional area of the thin portion is preferably 1/20 or more of the area of the opposing region. That is, in the illustrated example, the thickness T4 is preferably 1/20 or more of the thickness T3. If the cross-sectional area of the thin portion is too small, the thin portion 12 may break when the thin portion 12 is pulled between the first outer surface cushioning body 3 and the first corner cushioning body 2 . On the other hand, if the cross-sectional area of the thin portion is equal to or greater than the above value, breakage of the thin portion 12 can be reliably prevented.

When the second outer surface damping body 4 tries to move in the second direction 92 with respect to the first corner cushioning body 2 , the movement of the second outer surface damping body 4 is blocked by the thin portion 14 . In addition, the relationship between the first corner cushion 2, the second outer surface cushion 4, the thin portion 14, and the gap 15 is the first corner cushion 2, the first outer surface cushion 3, the thin portion 12, and the gap 15. Since it is the same as the relationship between the gaps 13, redundant description will be omitted.

The packing device 1D may include only one of the thin portion 12 and the thin portion 14 . In that case, the first corner cushioning body 3 and the second corner cushioning body 4 that are not connected to the first corner cushioning body 2 are protected from the first corner cushioning body 2 by the exterior material 6. prevented from moving away. Moreover, when the packaging device 1D includes both the thin-walled portion 12 and the thin-walled portion 14 as in the illustrated example, the packaging device 1D does not have to include the exterior material 6 . In this case, the thin portion 12 and the thin portion 14 function as first movement preventing means for preventing the first outer surface cushioning body 3 and the second outer surface cushioning body 4 from moving away from the first corner cushioning body 2 . Therefore, the same effects as those of the first embodiment can be obtained without the exterior material 6 .
