Description

Buffer material, packing device having the buffer material, and packing method

The present invention relates to a cushioning material used for packaging of a television set or the like, a packaging device having the cushioning material, and a packaging method.

As shown in FIGS. 5A and 5B,

conventional buffer materials

411, 412, and 413 are buffer materials 411 with respect to a plane outside the television set 400 with respect to a television set 400 using, for example, a CRT (Cathode Ray Tube). 412 and 413 (see, for example, Patent Document 1).

Also, for example, a television set using a PDP (PLASMA Display Panel) or LCD (Liquid Crystal Display) has a similar structure. As a result, when a TV set using a PDP or LCD is placed in a carton box with cushioning material, it will come into contact with the surface perpendicular to the falling direction and the surface of the cushioning material parallel to it. The cushioning effect is improved by crushing the cushioning material.

However, at present, it is becoming difficult to provide a flat shape on the side of the TV set as the TV set is made thinner. FIG. 6A is an example of a cross-sectional view of a television set 510 using a PDP or an LCD in a packed state. 6B is a partially enlarged view of a broken line portion shown in FIG. 6A. As shown in FIG. 6A, the television set 510 is housed in a packaging box 540 with side surfaces included in

cushioning materials

520 and 521.

As shown in FIGS. 6A and 6B, when the shape of the side surface 511 of the television set 510 has almost no flat surface, the surface-to-plane contact between the side surface 511 of the television set 510 and the side surface of the

cushioning materials

520 and 521 is performed as in the related art. I can't let you. Therefore, the conventional buffering effect cannot be expected by the

buffer materials

520 and 521.

In order to further reduce the thickness of the television set 510, it is necessary to obtain a conventional buffering effect and protect the television set 510 from impact during transportation even when a flat surface cannot be provided on the side surface of the television set 510. There is.

As described above, as the television set 510 becomes thinner, it has become difficult to provide a planar shape on the side surface of the television set 510. Furthermore, when the side surface of the television set 510 has a sharp shape, the shock-absorbing

materials

520 and 521 may be crushed as in the conventional case when the television set 510 is dropped in the side surface state in a packaging state in which the television set 510 is stored in the packaging box 540. However, the

buffer material

520 and 521 may be sheared instead of producing a buffer effect. As a result, the

buffer materials

520 and 521 may be separated. In this case, it is not possible to obtain a conventional buffering effect and protect the television set 510 from impact during transportation.

(Embodiment 1)
FIG. 1 is a schematic diagram illustrating a configuration after packing of the packing device according to Embodiment 1 of the present invention. FIG. 2 is an exploded view of the packing device according to Embodiment 1 of the present invention when packed. As shown in FIG. 1, the packaging device in Embodiment 1 of this invention is equipped with the television set 10 as an electronic component, the

edge buffer materials

20, 21, 23, and 24 as a buffer material, and the packaging box 40. As shown in FIG. . The TV set 10 has a thin width in the front-rear direction. The

end cushioning members

20, 21, 23, and 24 are disposed at the corners of the television set 10 and have a concave shape that includes the corners of the television set 10. The packaging box 40 holds and accommodates the corner portion of the television set 10 with the

end cushioning materials

20, 21, 23, and 24. As shown in FIGS. 1 and 2, the packaging device according to Embodiment 1 of the present invention further includes an upper cushioning material 22 and a lower cushioning material 25. The upper cushioning material 22 and the lower cushioning material 25 are disposed in order to mainly absorb the impact caused by the vertical drop of the television set 10 and obtain a cushioning effect.

FIG. 3A is a cross-sectional view showing an example of a packaging device according to Embodiment 1 of the present invention. FIG. 3A is a cross-sectional view looking down from the line 3A-3A showing the cross-section of FIG. 1, excluding the upper cushioning material 22 for easy understanding of the configuration of the packaging device.

As shown in FIG. 3A, the

end cushioning materials

20 and 21 are arranged at the corner portion of the television set 10 and include the corner portion of the television set 10. The

end cushioning materials

20 and 21 are provided with a set of

convex portions

20a and 20b and a set of

convex portions

20c and 20d at positions facing the front and back surfaces of the television set 10, respectively. A pair of

convex portions

20c and 20d may be provided, but it is desirable to further provide a pair of

convex portions

20e and 20f on the end cushioning material 21 as shown in FIG. 3A. That is, the

end cushioning materials

20 and 21 can be positioned in the front-rear direction with respect to the television set 10 by fitting the television set 10 and the

end cushioning materials

20 and 21 in one set of convex portions.

FIG. 3B is a partially enlarged view of a cross section of the packaging device according to Embodiment 1 of the present invention shown in FIG. 3A. As shown in FIG. 3B, the end cushioning material 20 is provided with a protrusion 30 at a position facing the side surface of the television set 10. Moreover, the arrow 26 has shown the side surface fall direction.

The projecting portion 30 is formed integrally with the end cushioning material 20 made of foamed polystyrene or the like at a position facing the side surface of the television set 10. Specifically, it is arranged at a position where the top of the projection 30 contacts the sharp part of the side surface of the television set 10 when dropped. As described above, the position of the television set 10 in the front-rear direction is restricted by the set of

convex portions

20a and 20b and the set of

convex portions

20c and 20d. Therefore, when the television set 10 falls in the direction of the arrow 26, the sharp part of the side surface of the television set 10 contacts the top of the projection 30 and the projection 30 is deformed or crushed.

The protrusion 30 is formed such that the periphery of the top is separated from the inner wall surfaces 22a and 22b of the end cushioning member 20. For this reason, the impact of the television set 10 on the protrusion 30 is received by the vicinity of the top of the protrusion 30 alone. If it is not separated from the inner wall surfaces 22a and 22b, if the protrusion 30 is buffered by an impact from the television set 10, the impact reaches the inner wall surfaces 22a and 22b as an influence thereof. When the impact reaches the inner wall surfaces 22a and 22b, a shearing force is generated between the protrusion 30 and the inner wall surfaces 22a and 22b. If shear force is generated between the protrusion 30 and the inner wall surfaces 22a and 22b, the end cushioning member 20 may be broken. In the present embodiment, the impact that the television set 10 exerts on the protrusion 30 is received by the vicinity of the top of the protrusion 30 alone, so even if the protrusion 30 is buffered, only the protrusion 30 is affected by the buffer. It will be. Therefore, the inner wall surfaces 22a and 22b are not affected by the impact. That is, in the present embodiment, the periphery of the top of the protrusion 30 is formed separately from the inner wall surfaces 22a and 22b of the end cushioning material 20, and therefore the end cushioning material 20 itself is unlikely to break.

As described above, the cushioning material in the present embodiment is disposed at the corner portion of the television set 10 as a thin electronic component having a thin width in the front-rear direction, and has a concave shape including the corner portion of the television set 10. Then, at least the corner portion of the television set 10 is held and accommodated in the packaging box 40. A set of convex portions is provided at positions facing the front and back surfaces of the TV set 10 and the TV set 10 is fitted to the TV set 10 by the one set of convex portions, thereby positioning the TV set 10 in the front-rear direction. A protrusion 30 is provided at a position facing the side surface of the television set 10.

In addition, if the impact due to the drop of the television set 10 is small, the deformation of the projection 30 due to the drop is recovered, so that the packaging device according to the present embodiment can cope with a plurality of drops.

In the present embodiment, the shape of the top of the protrusion 30 is a quadrangle, but the shape may be a rectangle, a circle, an ellipse, or a polygon with rounded corners. Moreover, although only one protrusion 30 may be formed on the end cushioning material 20, a plurality of protrusions 30 may be formed. This is preferable because the restoring force against deformation of the protrusion 30 is increased.

Note that the projection 31 provided on the end cushioning material 21 relaxes the impact of the television set 10 falling in the direction opposite to the arrow 26. That is, the protrusion 31 has a structure equivalent to that of the protrusion 30. Therefore, the end cushioning material 21 itself is unlikely to break.

Further, as shown in FIG. 2, the packaging device according to Embodiment 1 of the present invention further includes an upper cushioning material 22 and a lower cushioning material 25. The upper cushioning material 22 and the lower cushioning material 25 are disposed in order to mainly absorb the impact caused by the vertical drop of the television set 10 and obtain a cushioning effect. When the cross-sectional shape of the upper end surface and the lower end surface of the TV set 10 is sharp like the cross-sectional shape of the side surface, a protrusion having the same shape as the protrusion provided at the position facing the side surface as described above, It is desirable that the television set 10 is provided at a position facing the side surfaces of the upper end surface and the lower end surface. In this way, it is possible to mitigate the impact when dropping in the upward and downward directions. Further, the upper cushioning material 22 and the lower cushioning material 25 themselves are unlikely to break.

It should be noted that it is desirable to provide the above-described protrusions at positions facing the upper end surface and the side surfaces of the lower end surface of the television set 10 of the

end cushioning materials

20, 21, 23, and 24. In this way, the impact at the time of dropping in the upward and downward directions can be further alleviated. Further, the

end cushioning materials

20, 21, 23, 24 themselves are unlikely to break.

Next, the packing method in the embodiment of the present invention will be described. FIG. 4 is a flowchart showing an example of the packing method according to Embodiment 1 of the present invention.

As shown in FIG. 4, in the packing method according to the present embodiment, first, an end cushioning material as a cushioning material having a concave shape is formed at a corner portion of a television set 10 as a thin electronic component having a thin width in the front-rear direction. 20, 21, 23, and 24 are arranged (step S101). And the corner part of the television set 10 is included by the edge

part buffer materials

20, 21, 23, and 24 (step S102). Next, the television set 10 is held by the

end cushioning materials

20, 21, 23, and 24 and accommodated in the packaging box 40 (step S103).

Here, in the

end cushioning materials

20, 21, 23, and 24, a set of convex portions is positioned at positions facing the front and back of the television set 10 (step S104).

By positioning the TV set 10 and the

end cushioning materials

20, 21, 23, 24 in one set of convex portions, the

end cushioning materials

20, 21, 23, 24 are positioned in the front-rear direction with respect to the TV set 10 ( Step S105). In the

end cushioning materials

20, 21, 23, and 24, the protrusion is positioned at a position facing the side surface of the television set 10 (step S106). The periphery of the top of the protrusion is formed separately from the inner wall surfaces of the

end cushioning materials

20, 21, 23, and 24 (step S107).

Using the packing method described above, the top of the protrusion 30 is placed at a position where the top of the TV set 10 contacts the sharp part of the side of the TV set 10 when it falls. As described above, the position of the television set 10 in the front-rear direction is restricted by the set of

convex portions

20a and 20b and the set of

convex portions

The protrusion 30 is formed such that the periphery of the top is separated from the inner wall surfaces 22a and 22b of the end cushioning material 20. For this reason, even when the dropping direction indicated by the arrow 26 is slightly changed, the vicinity of the top of the protrusion 30 is deformed in accordance with the direction, so that the protrusion 30 itself is hardly sheared. In this way, in response to the drop in the direction of the arrow 26, the protrusion 30 is deformed or crushed, whereby the impact due to the drop of the television set 10 can be reduced. Further, the end cushioning material 20 itself is unlikely to break.

In the present embodiment, it is assumed that the position of the television set 10 in the front-rear direction is restricted by the one set of

convex portions

20a and 20b and the one set of

convex portions

20c and 20d. By doing so, it is easy to attach the cushioning material to the television set 10. However, the front-rear direction position of the television set 10 may be regulated by the wall surface of the shock-absorbing material without providing the shock-absorbing material with the pair of

convex portions

20a and 20b and the pair of

convex portions

20c and 20d. Even in this case, the position of the television set 10 in the front-rear direction can be restricted. However, it is somewhat difficult to attach the cushioning material to the television set 10 as compared with the case where the convex portion is not formed.

(Embodiment 2)
In the first embodiment, the protrusion 30 is provided at a position facing the side surface of the television set 10. The packaging device in the present embodiment is further different from the first embodiment in that a gap is formed between the television set 10 and the buffer material 20. FIG. 3C is a cross-sectional view showing an example of a packaging device according to Embodiment 2 of the present invention. FIG. 3D is a partially enlarged view of a cross section of the packaging device according to Embodiment 2 of the present invention.

As shown in FIG. 3D, the cushioning material 20 may be provided with a recess 31a so that a gap is formed between the television set 10 and the cushioning material 20. Similarly, you may provide the recessed part 31b in the buffer material 21 so that a space | gap may be formed between the television set 10 and the buffer material 21. FIG. As shown in FIG. 3D, the

concave portions

31 a and 31 b may be formed at one position near the center of the curved surface portion along the side surface of the curved surface portion of the television set 10. Or you may form a some recessed part along the side surface of a curved-surface part. In this way, the

convex portions

32a, 32b, 32c, and 32d are formed in the portions other than the

concave portions

31a and 31b of the

cushioning materials

20 and 21.

In this way, the shock generated in the side surface direction can be absorbed by the cushioning

material

20, 21

convex portions

32a, 32b, 32c, and 32d, so that the impact absorbing function can be further improved. Furthermore, the

convex portions

32 a, 32 b, 32 c, and 32 d of the

cushioning materials

20 and 21 formed by a plurality of concave portions may have substantially the same width and height as the protruding portion 30. That is, the plurality of

recesses

31 a and 31 b may be substantially equivalent to the

groove portions

22 c and 22 d formed on both end sides of the protrusion 30.

As shown in FIG. 3D, the width of the

groove portions

22 c and 22 d may be about ¼ or less of the width of the protruding portion 30. In addition, when the position of the portion where the sharp portion on the side surface of the TV set 10 abuts the protrusion 30 is represented by the boundary between one width 30a of the protrusion and the other width 30b of the protrusion, The other width 30b is preferably in a range from a position of about 1: 3 to 1: 1. In this way, even when the drop direction indicated by the arrow 26 is slightly changed, the vicinity of the top of the projection 30 is deformed corresponding to the direction, and thus the projection 30 itself is not easily sheared.

(Embodiment 3)
In the first embodiment, the protrusion 30 is provided at a position facing the side surface of the television set 10. The packaging device according to the present embodiment is different from the first embodiment in that a film that protects the top of the protrusion is formed. FIG. 3E is a cross-sectional view showing an example of a packaging device according to Embodiment 3 of the present invention. FIG. 3F is a partially enlarged view of a cross section of the packaging device according to Embodiment 3 of the present invention.

As shown in FIG. 3F, the protrusion 30e of the packaging device in the present embodiment further forms a coating 30g on the top of the protrusion 30 in FIG. 3B. When the television set 10 is dropped in the direction of the arrow 26 by forming the coating 30g, the sharp portion on the side surface of the television set 10 is in contact with the coating 30g on the top of the projection 30 and the projection 30 is deformed or crushed. Occurs. At this time, since the top of the protrusion 30 is protected by the coating 30g, the breakage is less likely to occur compared to the protrusion 30 of the packaging device in the first embodiment. The coating 30g may be formed by applying a resin or attaching a material on a thin film such as nylon. Further, it may be formed by adhering paperboard or cardboard.

(Embodiment 4)
In the first embodiment, the protrusion 30 is provided at a position facing the side surface of the television set 10. The packaging device according to the present embodiment is different from the first embodiment in that the protrusion is formed of a material having higher strength against breakage than the end cushioning material. FIG. 3G is a cross-sectional view showing an example of a packaging device according to Embodiment 4 of the present invention. FIG. 3H is a partially enlarged view of a cross section of the packaging device according to Embodiment 4 of the present invention.

As shown in FIG. 3G, the protrusion 30h of the packaging device in the present embodiment is formed of a material 30j having a higher strength against breakage than the end cushioning material 20, and is bonded to the end cushioning material 20 with an adhesive 30k. Form.

In this way, when the projection 30h is formed of the material 30j having high strength against breakage, when the television set 10 falls in the direction of the arrow 26, the sharp portion on the side surface of the television set 10 is the top of the projection 30h. The protrusion 30h is deformed or crushed. At this time, the top portion of the protrusion 30 h has higher strength against breakage than the end cushioning material 20, so that breakage is less likely to occur compared to the protrusion 30 of the packaging device in the first embodiment.

The present invention can be used as a cushioning material for a product that does not have a planar shape at a place where a cushioning material including a television set using a PDP or LCD touches.
