In the bent state, the buffer 100 is deformed along the object to be packaged 20 and is held so as to wrap the buffer 100. In other words, the buffer 100 is attached to the packaged object 20 by being in a bent state.
Here, the first axial direction is the Z direction shown in FIGS. 3 to 8 and the direction opposite to the Z direction (hereinafter, may be referred to as the −Z direction).
The second axial direction is the Y direction shown in FIGS. 3 to 8 and the direction opposite to the Y direction (hereinafter, may be referred to as the −Y direction).

In the present embodiment, as shown in FIG. 2, a case where the packaged object 20 has a rectangular parallelepiped shape (more specifically, a flat rectangular parallelepiped shape) will be described. The object to be packaged 20 is a pair of a front surface 21 and a back surface 22 (FIGS. 4 (a), (b), (c), 5 (b)) facing the opposite side of the front surface 21. (First pair of side surfaces) 23 and another pair of side surfaces (second pair of side surfaces) 24 facing opposite sides. Each side surface 23 is orthogonal to the front surface 21 and the back surface 22. Each side surface 24 is orthogonal to the front surface 21 and the back surface 22, and is also orthogonal to each side surface 23.
The packaged object 20 is not particularly limited, and may be a cosmetic container such as a compact case.
Then, in the bent state in which the shock absorber 100 is bent and the object to be packaged 20 is held by the shock absorber 100, an extension portion (connecting portion 2a of the second facing portion 2) is arranged on the back surface 22 and engages with the front surface 21. A piece (third facing portion 3) is arranged, and each of the first edge portion 11 and the second edge portion 12 is arranged along one of the first pair of side surfaces (pair of side surfaces 23). Moreover, it extends from the front surface 21 side to the back surface 22 side.

In the bent state, each of the pair of first facing portions 1 (each of the first edge portion 11 and the second edge portion 12) passes through one end and the other end of the object to be packaged 20 in the first axial direction and is the first. Standing upright with respect to the first and second planes orthogonal to the uniaxial direction, curved in the in-plane directions of the first and second planes, and viewed in the first axial direction. At that time, they are arranged at positions overlapping with the object to be packaged 20 (see FIGS. 5 (a), 5 (b), and 4 (b)).

Here, one end of the packaged object 20 in the first axial direction is one side surface 23 of a pair of side surfaces 23 (see also FIG. 3) facing each other, and the other end of the packaged object 20 in the first axial direction. Is the other side surface 23 of the pair of side surfaces 23 (see FIGS. 3 (b) and 4 (a)).
Further, the fact that the first plane passes through one end of the object to be packaged 20 in the first axial direction means that the first plane includes one end of the object to be packaged 20 in the first axial direction in the plane, and similarly. The fact that the second plane passes through the other end of the object to be packaged 20 in the first axial direction means that the second plane includes the other end of the object to be packaged 20 in the first axial direction in the plane.
In the case of the present embodiment, the first plane is a plane including one side surface 23, and the second plane is a plane including the other side surface 23.
The posture in which the first facing portion 1 (first edge portion 11) stands upright with respect to the first plane means that the plane direction of the first facing portion 1 stands upright in a state orthogonal to the first plane or in an inclined state. It means to be in a posture. It is permissible that one first facing portion 1 (first edge portion 11) is in a posture including a plurality of portions having different angles with respect to the first plane.
Similarly, when the first facing portion 1 (second edge portion 12) is in an upright posture with respect to the second plane, the plane direction of the first facing portion 1 is in an orthogonal state or an inclined state with respect to the second plane. It means that the posture is to stand up, and it is allowed that one first facing portion 1 (second edge portion 12) is in a posture including a plurality of portions having different angles with respect to the second plane.
Further, the fact that the first facing portion 1 (first edge portion 11, second edge portion 12) is curved may mean that the first facing portion 1 is curved in a curved surface shape, or the first facing portion 1 may be curved. The portion 1 may be in a bent form, or the first facing portion 1 may be in a form in which a curved surface bent portion and a bent portion are mixed.
Further, the fact that the first facing portion 1 is curved in the in-plane direction of the first plane means that the first facing portion 1 is curved along the first plane, and similarly, the first facing portion 1 is the first. Curved in the in-plane direction of the two planes means that the first facing portion 1 is curved along the second plane.
In the case of the present embodiment, in the bent state, each first facing portion 1 is in an upright state substantially orthogonal to each side surface 23 of the packaged object 20, and is V-shaped or U-shaped along each side surface 23. It curves in a shape (see FIGS. 4 (b), 5 (a), and (b)).
Further, it is said that the first facing portion 1 (the first edge portion 11 and the second edge portion 12) is arranged at a position where they overlap with the packaged object 20 when viewed in the first axial direction. It means that the whole or a part of 1 is arranged at a position overlapping with the packaged object 20 when viewed in the first axial direction. Here, it is preferable that at least a part of the curved portion of the first facing portion 1 is arranged at a position where it overlaps with the packaged object 20 when viewed in the first axial direction.

As the sheet body constituting the buffer body 100, a sheet body having appropriate flexibility and elasticity is preferably used. The material of the sheet body is not particularly limited, but a resin material such as polyethylene terephthalate or polypropylene is preferable. However, the sheet body may be paper.
When the sheet body is a resin material (when the sheet body is a resin sheet), the thickness of the sheet body is preferably about 0.1 mm or more and 0.5 mm or less, and preferably about 0.2 mm or more and 0.4 mm or less. Is even more preferable. By setting the thickness of the sheet body in this way, it is possible to improve the workability of the work of attaching the buffer 100 to the packaged object 20 and to improve the cushioning effect of the buffer 100.
The buffer 100 is preferably colorless and transparent, and is transparent to visible light. By doing so, it is possible to prevent the buffer 100 from obstructing the visibility of the inner package 20. However, the buffer 100 may be colored and transparent, or may be partially or wholly shaded, if necessary.

The buffer 100 is in a flat state (hereinafter, may be referred to as a normal state) in a normal state when no external force is applied, and the thickness of the buffer 100 is equal to the thickness of the sheet body.
By bending and deforming the buffer 100 by applying an external force, the buffer 100 can be made into a specific form (bent state).
The buffer 100 shown in FIGS. 1, 3 (a) and 9 is in a normal state, and FIGS. 3 (b), 4 (a) to (c), 5 (a), (b), and FIG. 7. The buffer 100 shown in FIGS. 8A to 8D is in a bent state.

In the bent state, the buffer 100 sandwiches the object to be packaged 20 in the first axial direction (Z direction, −Z direction) by the pair of first facing portions 1, and the second facing portion 2 and the third facing portion 3 The object to be packaged 20 can be sandwiched in the second axial direction (Y direction, −Y direction). Therefore, the packaged object 20 can be held by the buffer body 100 in a state where the relative movement of the packaged object 20 with respect to the buffer body 100 is restricted in the first axial direction and the second axial direction.
Then, as described above, each of the pair of first facing portions 1 is a first plane that passes through one end and the other end of the object to be packaged 20 in the first axial direction and is orthogonal to the first axial direction. In a posture of standing upright with respect to the second plane, curved in the in-plane direction of the first plane and the second plane, respectively, and at a position overlapping with the object to be packaged 20 when viewed in the first axial direction. Be placed. Therefore, a good cushioning effect can be obtained by each of the pair of first facing portions at the positions on both sides in the first axial direction with respect to the packaged object 20.

It can also be said that the pair of first facing portions 1 project from the packaged object 20 in the first axial direction in the bent state. That is, one first facing portion 1 protrudes from the packaged object 20 in the Z direction, and the other first facing portion 1 projects from the packaged object 20 in the −Z direction.

In the following description, for convenience, the positional relationship of each component of the buffer 100 may be described using the left, right, up, and down directions in FIG.

As shown in FIG. 1, in a flat state, the buffer 100 extends in parallel with each other and faces the first edge portion 11 and the second edge portion 12, and the first edge portion 11 and the second edge portion 12 It has a rectangular outer peripheral frame portion 10 including a third edge portion 13 and a fourth edge portion 14 that extend in a direction orthogonal to each other and face each other. The outer line of the outer peripheral frame portion 10 is also the outer line of the shock absorber 100, and therefore the shock absorber 100 is also rectangular.
Each of the first edge portion 11, the second edge portion 12, the third edge portion 13, and the fourth edge portion 14 is a strip-shaped portion having a predetermined width. One end of the first edge portion 11 and one end of the third edge portion 13 are connected to each other, and one end of the first edge portion 11 and the fourth edge portion 14 are connected to each other, and the third edge portion 13 The other end and one end of the second edge portion 12 are connected to each other, and the other end of the fourth edge portion 14 and the other end of the second edge portion 12 are connected to each other.
Then, one of the pair of first facing portions 1 is formed by the first edge portion 11 and the second edge portion 12.
The outer peripheral frame portion 10 preferably has a rectangular shape with rounded corners, which makes it easier to insert the bent buffer 100 into the box body 30, which will be described later, and also makes the corners of the outer peripheral frame portion 10 feel comfortable. Become soft.

In the bent state, each of the third edge portion 13 and the fourth edge portion 14 protrudes from the packaged object 20 in the third axial direction orthogonal to both the first axial direction and the second axial direction. ..
The third axis direction is the X direction shown in FIGS. 3 to 8 and the direction opposite to the X direction (hereinafter, may be referred to as −X direction).
That is, as shown in FIGS. 3 (b), 4 (a), (b), (c), 5 (a), and (b), the third edge portion 13 is in the −X direction from the packaged object 20. The fourth edge portion 14 projects in the X direction from the packaged object 20.
In other words, in the bent state, each of the third edge portion 13 and the fourth edge portion 14 protrudes more than one of the pair of side surfaces 24 (second pair of side surfaces).
Therefore, a good cushioning effect can be obtained by each of the third edge portion 13 and the fourth edge portion 14 at the positions on both sides in the third axial direction with respect to the packaged object 20.

Further, in the bent state, each of the third edge portion 13 and the fourth edge portion 14 is on the opposite side (-Y) from the packaged object 20 to the second facing portion 2 (extending portion) side in the second axial direction. Protruding in the direction).
In other words, in the bent state, each of the third edge portion 13 and the fourth edge portion 14 protrudes from the front surface 21.
Therefore, a good cushioning effect can be obtained by each of the third edge portion 13 and the fourth edge portion 14 at a position opposite to the second facing portion 2 side with respect to the packaged object 20 in the second axial direction. Be done.
As described above, since the third edge portion 13 and the fourth edge portion 14 project from the packaged object 20 in the −Y direction as well, the cushioning function in the third axial direction (X direction or −X direction) and −Y It also serves as a buffer function in the direction.

In the case of the present embodiment, the second facing portion 2 extends between the pair of first facing portions 1 and connects the pair of first facing portions 1 to each other. More specifically, one end of the second facing portion 2 is connected to the inside of the central portion in the longitudinal direction (horizontal direction in FIG. 1) of one first facing portion 1 (first edge portion 11), and the other first. The other end of the second facing portion 2 is connected to the inside of the central portion in the longitudinal direction (left-right direction in FIG. 1) of the facing portion 1 (second edge portion 12).
That is, the extending portion (connecting portion 2a of the second facing portion 2) extends over an intermediate portion between both ends of the first edge portion 11 and an intermediate portion between both ends of the second edge portion 12. , The first edge portion 11 and the second edge portion 12 are connected to each other.
Since the second facing portion 2 connects the pair of first facing portions 1 to each other, the object to be packaged 20 can be more stably sandwiched by the pair of first facing portions 1, and the back surface is supported by the second facing portion 2. Since 22 can be held more stably, the object to be packaged 20 can be held more stably by the buffer 100.

Further, in FIG. 1, the second facing portion 2 has one connecting portion 2a arranged at the central portion of the pair of first facing portions 1 in the left-right direction. Therefore, the V-shape or U-shape formed by each first facing portion 1 curved along the side surface 23 has a good symmetry with respect to the connecting portion 2a. Therefore, each side surface 23 can be stably and well-balanced by each first facing portion 1.

In the case of the present embodiment, the second facing portion 2 is connected to the connecting portion 2a extending in a direction orthogonal to the pair of first facing portions 1 and connecting the pair of first facing portions 1 to each other. It is configured to include a cross extending portion 2b extending from the portion 2a in the intersecting direction with respect to the longitudinal direction (vertical direction in FIG. 1) of the connecting portion 2a.
More specifically, a pair of left and right cross extending portions 2b extend from the end of the connecting portion 2a on the first edge portion 11 side, and from the end of the connecting portion 2a on the second edge portion 12 side. Also, a pair of left and right cross extending portions 2b extend respectively.
In other words, it can be said that a pair of cross extending portions 2b extend from the connecting portion 2a toward the left side and the right side respectively.

In the bent state, the second facing portion 2 including the connecting portion (extending portion) 2a is orthogonal to the second axial direction (Y direction, −Y direction), and the second facing portion 2 in the packaged object 20 It is arranged along the side end (in the case of this embodiment, the back surface 22) (see FIGS. 4 (a), (b), (c), and 5 (b)).
Therefore, the back surface 22 of the object to be packaged 20 can be stably supported by the second facing portion 2 including the connecting portion (extending portion) 2a.

On the other hand, the third facing portion 3 is connected to the inside of each of the third edge portion 13 and the fourth edge portion 14.
More specifically, the third facing portion 3 is arranged at each of the four inner corners of the outer peripheral frame portion 10, and is the length of the first edge portion 11 and the second edge portion 12 from the third edge portion 13 and the fourth edge portion 14. It is a projectile extending in the vertical direction.
That is, in the case of the present embodiment, the buffer 100 has four third facing portions 3.
Since the object to be packaged 20 can be held by the four third facing portions 3, the object to be packaged 20 can be stably held by the buffer 100.

In the bent state, the third facing portion (engagement piece) 3 is arranged along the edge portion of the surface of the object to be packaged 20 on the side facing the third facing portion (in the case of the present embodiment, the front surface 21). More specifically, each third facing portion 3 is arranged along each of the four corners of the front surface 21.
As a result, in the bent state, the front surface 21 is exposed from the buffer 100 except for the edges (specifically, the four corners) of the front surface 21.

The tip of the third facing portion 3 is preferably rounded, whereby it is possible to prevent the third facing portion 3 from damaging the packaged object 20.
Since there is a trade-off between the magnitude of the holding force of the object to be packaged 20 by the third facing portion 3 and the visibility (displayability) of the front surface 21 of the object to be packaged 20, the third facing portion 3 has a trade-off relationship. The dimensions are set appropriately as required.

Further, a protruding portion 5 is connected to the tip end side of each intersecting extending portion 2b of the second facing portion 2. That is, in the case of the present embodiment, the buffer 100 has four protrusions 5. In the bent state, the protruding portion 5 protrudes from the packaged object 20 in the third axial direction orthogonal to both the first axial direction and the second axial direction.
The third axis direction is the X direction shown in FIGS. 3 to 8 and the direction opposite to the X direction (hereinafter, may be referred to as −X direction).
In other words, in the bent state, each of the third extension portions (the portion including the cross extension portion 2b and the protrusion 5) is arranged along the back surface 22 and the tip portion of the third extension portion. (Protruding portion 5) protrudes more than one of each of the second pair of side surfaces (pair of side surfaces 24).

Therefore, a good cushioning effect can be obtained by the second protruding portion 6 at a position opposite to the third facing portion 3 side with respect to the packaged object 20 in the second axial direction.

As described above, in the bent state, a part of the buffer 100 projects in all six directions (Z direction, −Z direction, Y direction, −Y direction, X direction, −X direction) of the packaged object 20. In other words, in the bent state, the buffer 100 has ribs (ribs composed of parts of the buffer 100) standing upright in all six directions of the packaged object 20. Therefore, the buffer 100 can protect the object to be packaged 20 in all six directions.

Further, an engaging portion 7 is formed on the protruding portion 5, and a second engaging portion 8 is formed on the second protruding portion 6.
Then, in the bent state, the engaging portion 7 and the second engaging portion 8 are engaged with each other (FIGS. 4 (a), 4 (c), 5 (a), (b)). reference).
In a state where the engaging portion 7 and the second engaging portion 8 are engaged, the movement of the protruding portion 5 in the protruding direction of the second protruding portion 6 is restricted, and the second protruding portion 5 is restricted from moving in the protruding direction. The movement of the protruding portion 6 and the fourth facing portion 4 is restricted. Therefore, the three-dimensional shape of the buffer 100 is stable.
More specifically, in FIG. 1, the upper left protruding portion 5 has an engaging portion 7 projecting below the upper left crossing extending portion 2b, and the left second protruding portion 6 has a left fourth facing portion. Second engaging portions 8 projecting above 4 are formed, respectively, and the proximal end portion 7a and the proximal end portion 8a of the engaging portion 7 and the second engaging portion 8 engage with each other. .. The base end portion 7a and the base end portion 8a that engage with each other are arranged at the same positions in the vertical direction of FIG.

The movement of the second extension in the extension direction of the third extension is restricted.

Here, it is preferable that at least one of the base end portion 7a and the base end portion 8a is formed in a notched shape (a constriction is formed). In the case of the present embodiment, as described above, the width of the fourth facing portion 4 is narrowed in front of the second engaging portion 8, so that a constriction is formed at the base end portion 8a of the second engaging portion 8. There is. By doing so, the engaged state between the engaging portion 7 and the second engaging portion 8 can be maintained more stably. In the case of the present embodiment, the base end portion 8a of the second engaging portion 8 is formed in a notched shape.

Although the example in which the engaging portion 7 and the second engaging portion 8 are engaged in a total of four locations has been described here, the engaging portion between the engaging portion 7 and the second engaging portion 8 is described. The number of points is not limited to four, and can be appropriately set within a range of one or more and eight or less, for example. From the viewpoint of improving the stability of the three-dimensional shape of the shock absorber 100 in the bent state, it is preferable that the engagement points are even numbers.

In addition, in FIG. 1, slit-shaped openings 9 are formed on the left and right sides of the second facing portion 2 so as to penetrate the front and back surfaces of the buffer 100, whereby the pair of first facing portions 1 ( The first edge portion 11 and the second edge portion 12) can be easily bent and deformed, and the pair of fourth facing portions 4 can be easily bent and deformed at their respective roots.

By doing so, the stress concentration at these joints can be relaxed, so that the impact resistance of the outer peripheral frame portion 10 can be improved.
As for the other portions, the inner edge of the opening 9 is preferably formed in a gentle curved shape except for the proximal end portion 7a of the engaging portion 7 and the proximal end portion 8a of the second engaging portion 8. As a result, stress concentration at each portion of the inner edge of the opening 9 can be relaxed.

Further, each first facing portion 1 is formed with ruled lines 15 extending in the width direction of the first facing portion 1 at both side positions sandwiching the connecting portion between the first facing portion 1 and the second facing portion 2. ing. That is, a pair of ruled lines 15 are formed on each of the first facing portions 1. As a result, the first facing portion 1 can be easily bent and deformed at the ruled line 15.
More specifically, each of the pair of ruled lines 15 formed on the first facing portion 1 is linear, and the pair of ruled lines 15 are formed from the inside to the outside of the first facing portion 1. We are approaching each other. As a result, when the first facing portion 1 receives an external force in the first axial direction, the first facing portion 1 can be twisted and deformed to absorb the external force, so that the first facing portion 1 provides excellent cushioning. The effect is obtained.

The buffer 100 can be obtained, for example, by cutting and separating the original fabric of the sheet body by punching or the like. The ruled line 15 is, for example, a half-cut line or a perforation, and can be formed on one side or both sides of the first facing portion 1 by using a Thomson blade or the like during punching.

The shock absorber 100 has a symmetrical shape to the left and right in FIG. 1, and also has a symmetrical shape to the top and bottom of FIG.

An insertion piece 35 is connected to the rotation tip side of each side wall portion 33, and the insertion piece 35 is spaced along the inner surface of the back wall portion 32 so as to face the back wall portion 32 and the front wall portion 31. When inserted, the box body 30 is closed by the side wall portion 33.
At least the front wall portion 31 of the box body 30 is visible light transmissive, and preferably the entire box body 30 is visible light transmissive. The box body 30 is made of a transparent (for example, colorless and transparent) resin material. However, the box body 30 may be colored and transparent, or may be partially light-shielded, if necessary.

In the packaged object 20 held by the buffer 100, the front surface 21 is located on the front wall portion 31 side and faces the front wall portion 31, and the back surface 22 is located on the back wall portion 32 side and is located on the back wall portion 32. It is inserted into the box body 30 so that each side surface 23 faces each side wall portion 33 and each side surface 24 faces each side wall portion 34. After that, the side wall portion 33 is closed, and the side wall portion 33 is fixed to the back wall portion 32 or the side wall portion 34 by a fixture such as an adhesive tape. In this way, the packaged object 20 held by the buffer 100 is housed in the box 30 together with the buffer 100 (see FIG. 7).

Here, the packaging kit 200 (FIG. 7) according to the present embodiment is configured by the buffer 100 and the box 30.

Further, the packaging kit 200 and the object to be packaged 20 constitute the packaging body 300 according to the present embodiment.

More specifically, as shown in FIG. 7, the packaged object 20 is held by the shock absorber 100 in the bent state, and the box body 30 is in a state where the packaged object 20 and the buffer body 100 are housed in the box body 30. Two sides (side 31a shown in FIG. 7) facing each other on the wall surface portion (front wall portion 31) on the third side (−Y direction side) of the third facing portion (engagement piece) in the second axial direction. A third edge portion 13 and a fourth edge portion 14 extend along each of the above.
In other words, the outer side of the third edge portion 13 extends along one side 31a (that is, the line of intersection between the front wall portion 31 and the one side wall portion 34), and the fourth facing portion 4 The outer side of the is extending along the other side 31a (that is, the line of intersection between the front wall portion 31 and the other side wall portion 34).
As a result, the buffer 100 is stably held by the box 30 in the box 30.

Further, as shown in FIG. 8A, in a state where the object to be packaged 20 is held by the shock absorber 100 in the bent state, the object to be packaged is packaged from the third facing portion (engaging piece) 3 side in the second axial direction. When the object 20 is viewed, the outer peripheral frame portion 10 surrounds the outer periphery of the object to be packaged 20, and the third facing portion 3 is located at the edge portion (more specifically, each of the four corners) of the object to be packaged 20. The surface (front surface 21) of the object to be packaged 20 on the third facing portion 3 side is exposed from the buffer 100 except for the peripheral edge of the surface.
Here, as described above, the front wall portion 31 of the box body 30 is visible light transmissive, and preferably the entire box body 30 is visible light transmissive. That is, in the box body 30, at least the wall surface portion (front wall portion 31) on the third facing portion 3 side in the second axial direction is visible light transmissive.
Therefore, when the packaged object 20 housed in the box body 30 is viewed from the third facing portion 3 side in the second axial direction, the packaged object 20 is on the front side of the front surface 21 other than the third facing portion 3. The component of the buffer 100 is substantially absent, and almost the entire front surface 21 is exposed from the buffer 100.
Therefore, the package 300 can be displayed at a store or the like with good visibility of the front surface 21.
