The packaging box disclosed in the present specification is provided with an exterior unit, and packaging components set in the exterior unit. The above packaging components include an article mounting plane unit on which to mount an article, a pair of suspending units made by bending the article mounting plane unit upward at both ends in order to suspend the article mounting plane unit, and a pair of side plane units made by bending the pair of suspending units downward. The above pair of side plane units are kept in surface contact with two opposing walls of the above exterior unit.
The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention as claimed.
The above packaging components that are made by bending an article mounting plane unit at a right angle to form the leg units and bottom unit are configured to transmit impact forces from the bottom to the top linearly (forces are not dispersed) when a packaging box drops.
Also, the weight of an article is always applied to the article mounting plane unit, and thus the article mounting plane unit is easily crushed when the article is transported for a long period of time. Accordingly, when an article is heavy, a remarkable amount of bending occurs in the article mounting plane unit. This leads to a situation where the impact force caused by the dropping of a packaging box makes the article itself abut the bottom unit of an exterior unit together with the article mounting plane unit.
Further, if a packaging component is to be bent in a complicated manner, a greater number of steps are required, and bending mistakes easily occur. Also, a packaging component gets out of shape easily, making it difficult to set an article in the packaging box in a process of storing a packaging component in the packaging box.
Also, the above packaging component including leg units that are made by bending a pair of suspending units in such a manner that they are open outward and downward includes the upper ends of the leg units that are free ends, and accordingly it is difficult to absorb impact forces caused in the dropping direction at a spot away of the bottom plane. Also, vibrations and impact forces caused during transportation can be absorbed only by a single path of suspending. Accordingly, when transportation continues for a long period of time, the shock absorbing ability of the article mounting plane unit decreases.
Also, the above packaging box including a prepackaged-item box to store accessories as shock-absorbing material under the article mounting plane unit on which an article is mounted always receives stresses to the shock-absorbing material and the article mounting plane unit from below. This means that the shock absorbing ability of the article mounting plane unit decreases, and this type of box always needs shock-absorbing material.
Hereinafter, a packaging box according to embodiments will be explained by referring to drawings.
First EmbodimentAs illustrated in
The packaging component 10 includes an article mounting plane unit 11, a pair of suspending units 12 and 13, a pair of side plane units 14 and 15, and a pair of downward-bent units 16 and 17, and is set in the exterior unit 20. The packaging component 10 is made of a single base board such as, for example, corrugated cardboard.
The exterior unit 20 includes a left plane unit 21, a back plane unit 22, a right plane unit 23, and a front plane unit 24, a top plane unit 25, and a bottom plane unit 26, and the top plane unit 25 functions as, for example, an openable and closable lid.
The article mounting plane unit 11 is a rectangular shape that is, for example, longer in the lateral direction than in the front-back direction, and is kept horizontal. On the top plane of the article mounting plane unit 11, which serves as the article mounting plane, an article 100 such as an electronic device is mounted (held).
The article 100 is held on the article mounting plane unit 11 by being covered by, for example, elastic film F represented by the chain double-dashed line in

As illustrated in
Through holes 12a and 13a are formed on the pair of suspending units 12 and 13 so that fingers can be inserted into them when the packaging component 10 is to be removed. These through holes 12a and 13a are in communication with through holes 14a and 15a on the pair of side plane units 14 and 15 that will be described later.
The pair of suspending units 12 and 13 include small width units 12b and 13b that are continuous to the article mounting plane unit 11, and include large width units 12c and 13c that are continuous to the pair of side plane units 14 and 15.
The width of the small width units 12b and 13b (the front-back dimension) is equal, at their lower ends, to the dimension of the article mounting plane unit 11 in the front-back direction, and becomes smaller as the distances on the units to the large width units 12c and 13c (see
The pair of side plane units 14 and 15 are made by bending, downward and outward (convex folds M) (i.e., to the sides opposite from the article mounting plane unit 11), the pair of suspending units 12 and 13 at their top ends. Also, the pair of side plane units 14 and 15 are kept in surface contact with the left plane unit 21 and the right plane unit 23 of the exterior unit 20 (examples of two opposing walls).
Width W, depth L, and height H of the packaging component 10 illustrated in
The pair of side plane units 14 and 15 are positioned by the above dimensional relationships (especially by width W of the packaging component 10), and are kept in surface contact with the left plane unit 21 and the right plane unit 23.
Additionally, the depth and the height of the pair of side plane units 14 and 15 are identical to depth L and height H of the packaging component 10; in other words, they are identical or almost identical to the depth and the height of the inner dimensions of the exterior unit 20. Accordingly, the pair of side plane units 14 and 15 are in contact with the bottom plane unit 26, the front plane unit 24, and the back plane unit 22 of the exterior unit 20 so that shaking is suppressed.
Additionally, it is also possible to tightly connect the upper ends of the side plane units 14 and 15 to the exterior unit 20 by employing height H of the pair of side plane units 14 and 15, which is greater than the inner dimension of the exterior unit 20, so that the top plane unit 25 and the bottom plane unit 26 of the exterior unit 20 crush the side plane units 14 and 15. This also increases the compression strength of the packaging box 1.
The depth and the height of the pair of side plane units 14 and 15 are desirably identical or almost identical to the inner dimensions of the exterior unit 20. However, they may be smaller than the inner dimensions of the exterior unit 20 so as to allow for slight movement in the vertical and horizontal directions. Also, it is also possible to freely adjust the propagation order (transmission speed) of impacts applied to the article 100 by adjusting the dimensions of the pair of side plane units 14 and 15, the pair of downward-bent units 16 and 17, and the exterior unit 20.
The left plane unit 21 and the right plane unit 23 of the exterior unit 20 are parallel to each other, and the pair of side plane units 14 and 15 are made by bending, vertically and downward, the pair of suspending units 12 and 13 at their upper ends.
As illustrated in
As illustrated in
The lateral dimensions of the main body units 16a and 17a are identical to those of the article mounting plane unit 11 at their upper ends, and become smaller as the distance on the main body units 16a and 17a to the bottom decreases.
The left-hand side triangle units 16b and 17b, and the right-hand side triangle units 16c and 17c are triangular, and are angled obliquely upward (convex folds M) in such a manner that they get further from each other as the distance on them from the left and right ends of the main body units 16a and 17a increases.
The left end units 16d and 17d, and the right end units 16e and 17e are angled upward from the left-hand side triangle units 16b and 17b or the right-hand side triangle units 16c and 17c (convex folds M), and are inserted between the pair of suspending units 12 and 13 and the pair of side plane units 14 and 15. Additionally, the left end units 16d and 17d and the right end units 16e and 17e are made by bending the pair of suspending units 12 and 13 in a manner of convex fold M.
As illustrated in
The pair of center-side oblique plane units 32 and 33 are angled so as to form the shape “V”, and are in surface contact with the outer surfaces of the main body units 16a and 17a of the pair of downward-bent units 16 and 17.
The pair of outer-side oblique plane units 31 and 34 are angled obliquely downward in such a manner that they get further from each other as the distance on them from the upper ends of the pair of center-side oblique plane units 32 and 33 increases. The lower ends of the pair of outer-side oblique plane units 31 and 34 are at the corners between the left plane unit 21 and the bottom plane unit 26 of the exterior unit 20 or between the right plane unit 23 and the bottom plane unit 26 of the exterior unit 20.
The supporting unit 30 supports the pair of downward-bent units 16 and 17 by the pair of center-side oblique plane units 32 and 33 being in surface contact with the outer surfaces of the main body units 16a and 17a of the downward-bent units 16 and 17. In addition, the pair of center-side oblique plane units 32 and 33 may be set with spaces with respect to the outer surfaces of the main body units 16a and 17a of the downward-bent units 16 and 17 without being in surface contact as long as they get in surface contact when, for example, the packaging box 1 drops.
The lower ends of the main body units 16a and 17a of the pair of downward-bent units 16 and 17 do not abut the pair of center-side oblique plane units 32 and 33 of the supporting unit 30. However, it is possible for them to abut when vertical impact forces are applied upwardly from the bottom plane unit 26 of the exterior unit 20.
It is also possible for the lower ends of the main body units 16a and 17a to always be in contact with the pair of center-side oblique plane units 32 and 33. Also, the supporting unit 30 is set over the entire bottom plane unit 26 of the exterior unit 20 in the present embodiment. However, a plurality of supporting units 30 may be arranged in the height direction with partition plates between them so as to enhance their shock absorbing ability.
The pair of downward-bent units 16 and 17 are angled obliquely downward in such a manner that they get closer to each other as the distance on them from the front and back ends of the article mounting plane unit 11 increases. Accordingly, even when the pair of downward-bent units 16 and 17 abut the corner between the pair of center-side oblique plane units 32 and 33 of the supporting unit 30, an impact force (F1) applied vertically upward from the bottom plane unit 26 of the exterior unit 20 is dispersed in a direction along which the pair of downward-bent units 16 and 17 are slanted (forces F3), as illustrated in
Further, as has been described above, the pair of center-side oblique plane units 32 and 33 are in surface contact with the outer surfaces of the main body units 16a and 17a of the downward-bent units 16 and 17, and accordingly impact force (F1) applied vertically upward from the bottom plane unit 26 is dispersed also on the supporting unit 30 by the surface contact (forces 2). Then, they are converted into forces tensioning the article mounting plane unit 11 in the front and back directions (F4).
Also, when the article is, for example, 10 Kg or lighter, it is recommended that a free-fall test (for example, JIS 20200) in which the packaging box 1 is subject to free fall from a height of 80 cm with respect to one corner, three edges, and six planes be performed.
Although
Specifically, the left plane unit 21, the right plane unit 23, and the front plane unit 24 include outer surface units 21a, 23a, and 24a, and also include inner surface units 21b, 23b, and 24b, which are made by bending downward the outer surface units 21a and 23a at their upper ends.
Between the left plane unit 21/right plane unit 23 and the front plane unit 24, interspaces serving as guides G into which the pair of side plane units 14 and 15 are inserted are formed. The pair of side plane units 14 and 15 are positioned not only by the dimensional relationships with the above packaging component 10 (particularly width W) but also by guides G, and are kept in surface contact with the left plane unit 21 and the right plane unit 23.
As illustrated in
An insertion tip unit 24d that is bent inward (to the back side) in a manner of a convex fold M is formed at the tip of the insertion base end unit 24c. This insertion tip unit 24d is inserted into an insertion port 25b of the top plane unit 25 that will be explained later in
At the center of the upper end of the insertion base end unit 24c, a semicircular knob unit 24e is formed. As illustrated in
An insertion unit 25a of the top plane unit 25 illustrated in
The insertion tip unit 24d of the front plane unit 24 is inserted into the insertion port 25b of the top plane unit 25 while being in an inserted state into the insertion port 24f.
Hereinafter, explanations will be given for how to take out the article 100 from the packaging box 1.
First, as illustrated in
Next, when there is a prepackaged item such as printed materials or the like above the article 100, the prepackaged item is taken out first. Then, as illustrated in
When the lower ends of the pair of side plane units 14 and 15 are opened in such a manner that they get further from each other as illustrated in
In the first embodiment, which has been described before, the packaging component 10 of the packaging box 1 includes the pair of suspending units 12 and 13 that are made by bending the article mounting plane unit 11 at the left and right ends upward so as to suspend the article mounting plane unit 11, and the pair of side plane units 14 and 15 made by bending the suspending units 12 and 13 at their upper ends downward. Also, the pair of side plane units 14 and 15 are kept in surface contact with the left plane unit 21 and the right plane unit 23 (two opposing walls) of the exterior unit 20.
Accordingly, even when complicated structures or shock absorbing materials are omitted, the pair of side plane units 14 and 15 in surface contact with the left plane unit 21 and the right plane unit 23 of the exterior unit 20 are able to support the suspending units 12 and 13 securely. Thus, the present embodiment makes it possible to enhance the shock absorbing ability of the packaging box 1 with a simple configuration. Thereby, it is also possible to use thinner materials for the packaging box 1, and to make the exterior unit (packaging box 1) more compact.
Also, in the present embodiment, the packaging component 10 includes the pair of downward-bent units 16 and 17 made by bending the article mounting plane unit 11 obliquely downward at the front and back ends in such a manner that they get closer to each other as the distance on them from the front and back ends increases. This pair of downward-bent units 16 and 17 disperse an impact force (F1) applied upward from the bottom plane unit 26 of the exterior unit 20 vertically, in the direction along which the pair of downward-bent units 16 and 17 are angled (forces F3), and convert them into forces that tension the article mounting plane unit 11 in the front and back directions (F4). In other words, the article mounting plane unit 11 is prevented from being deflected by the weight of the article 100. Thus, the shock absorbing ability of the packaging box 1 can be enhanced.
Also, in the present embodiment, the supporting unit 30 is set on the bottom plane unit 26 of the exterior unit 20, and is in surface contact with the outer surfaces of the pair of downward-bent units 16 and 17 (the main body units 16a and 17a) in order to support the downward-bent units 16 and 17. Accordingly, the above surface contact converts impact force (F1) applied from the bottom plane unit 26 vertically and upwardly into forces tensioning the article mounting plane unit 11 in the front and back directions (F4). This can enhance the shock absorbing ability of the packaging box 1.
Also, in the present embodiment, the pair of center-side oblique plane units 32 and 33 are angled so as to form a “V” shape, and are in surface contact with the outer surfaces of the pair of downward-bent units 16 and 17 (the main body units 16a and 17a). Also, the pair of outer-side oblique plane units 31 and 34 are made by bending, obliquely downward, the pair of center-side oblique plane units 32 and 33 at their upper ends in such a manner that the outer side oblique plane units 31 and 34 get further from each other as the distance on the units 31 and 34 from the upper ends of the center-side oblique plane units 32 and 33 increases. Accordingly, the truss structure composed of the supporting unit 30 and the downward-bent units 16 and 17 leads to further enhancement of the shock absorbing ability of the packaging box 1.
Also, in the present embodiment, there are interspaces S3 and S4 between the exterior unit 20 and the front/back ends of the article mounting plane unit 11. Accordingly, it is possible to prevent impact forces applied to the front plane unit 24 or the back plane unit 22 from being transmitted to the article mounting plane unit 11, or the article 100.
Also, the small storage box 200 is set in the interspaces S3 or S4 between the exterior unit 20 and the front/back ends of the article mounting plane unit 11 in order to store items other than the article 100. Thereby, it is possible to employ a simpler configuration for the packaging box 1 by utilizing the interspaces S3 and S4. This can reduce the number of packaging boxes by, for example, omitting packaging boxes that have been used independently.
The packaging box 1-1 illustrated in
The packaging box 2 according to the present embodiment is different from the above first embodiment in that the supporting unit 30 is omitted and reinforcement ribs (an example of reinforcement units) 44b, 44c, 45b, and 45c, notches 46g, 46h, 47g, and 47h, and falling off prevention convex portions 41a and 41b are employed. The present embodiment is similar to the first embodiment in the other aspects, and thus explanations thereof will be omitted.
The packaging box 2 illustrated in
The packaging component 40 includes an article mounting plane unit 41, a pair of suspending units 42 and 43, a pair of side plane units 44 and 45, and a pair of downward-bent units 46 and 47.
The falling off prevention convex portions 41a and 41b are formed on the article mounting plane unit 41 in order to prevent the article 100 from falling out. These falling off prevention convex portions 41a and 41b are formed by, for example, making rectangular cuts on the article mounting plane unit 41.
As illustrated in
Films F are inserted between the article mounting plane unit 41 and the falling off prevention convex portions 41a/41b so that the article 100 is prevented from falling off the article mounting plane unit 41 (films F).
The pair of side plane units 44 and 45 include the reinforcement ribs 44b, 44c, 45b, and 45c that support the downward-bent units 46 and 47. These reinforcement ribs 44b, 44c, 45b, and 45c are formed by bending the pair of side plane units 44 and 45 at lower portions of their front and back ends in a manner of convex fold M.
Each of the reinforcement ribs 44b, 44c, 45b, and 45c is a triangle composed of a side formed by the lower portion of the front or back end of the pair of side plane units 44 and 45, a side formed of the line bordering on the bottom plane unit 26 of the exterior unit 20, and a side formed by the line bordering on the pair of downward-bent units 46 and 47.
The pair of downward-bent units 46 and 47 include the notches 46g, 46h, 47g, and 47h that are engaged with the reinforcement ribs 44b, 44c, 45b, and 45c.

The pair of downward-bent units 46 and 47 according to the present embodiment also include main body units 46a and 47a, left-hand side triangle units 46b and 47b, right-hand side triangle units 46c and 47c, left end units 46d and 47d, right end units 46e and 47e, and adherence areas 46f and 47f similar to those in the first embodiment.
Also in the above second embodiment, the same effect as that of the first embodiment can be achieved, i.e., the enhancement of the shock absorbing ability of the packaging box 2 with a simple configuration and the like.
Further, in the present embodiment, the pair of side plane units 44 and 45 include the reinforcement ribs 44b, 44c, 45b, and 45c to support the pair of downward-bent units 46 and 47. Accordingly, the entire downward-bent units 46 and 47 support the article mounting plane unit 41 to absorb forces, and thereby the shock absorbing ability of the packaging box 2 can be enhanced further.
Also, in the present embodiment, the reinforcement ribs 44b, 44c, 45b, and 45c are formed by bending the pair of side plane units 44 and 45 at the lower portions of their front and back ends. Accordingly, the pair of side plane units 44 and 45 and the downward-bent units 46 and 47 function as a single unit so as to support the article mounting plane unit 41, leading to further enhancement of the shock absorbing ability of the packaging box 2.
Also, in the present embodiment, each of the reinforcement ribs 44b, 44c, 45b, and 45c is a triangle composed of a side formed by the lower portion of the front or back end of the pair of side plane units 44 and 45, a side formed by the portion bordering on the bottom plane unit 26 of the exterior unit 20, and a side formed by the portion bordering on the pair of downward-bent units 46 and 47. This leads to further enhancement of the shock absorbing ability of the packaging box 2.
Also, in the present embodiment, the pair of downward-bent units 46 and 47 include the notches 46g, 46h, 47g, and 47h that are engaged with the reinforcement ribs 44b, 44c, 45b, and 45c, leading to further enhancement of the shock absorbing ability of the packaging box 2.
Also, as illustrated in
Also, in the present embodiment, the article mounting plane unit 41 includes the falling off prevention convex portions 41a and 41b to prevent the article 100 from falling off, and these falling off prevention convex portions 41a and 41b are formed by making cuts on the article mounting plane unit 41. This makes it possible to prevent the article 100 from falling off with a simple configuration.
Third EmbodimentThe packaging box 3 according to the present embodiment is different from the first embodiment in that the packaging box 3 includes convex units 52d, 53e, 53d, and 53e of a pair of suspending units 52 and 53, and convex units (an example of engagement units) 54b, 54c, 55b, and 55c of a pair of side plane units 54 and 55, belt units 58, and a partition unit 59. The present embodiment is similar to the first embodiment in the other aspects, and thus explanations thereof will be omitted.
The packaging component 50 illustrated in
The convex units 52d, 53e, 53d, 53e, 54b, 54c, 55b, and 55c are formed on the pair of suspending units 52 and 53 and the pair of side plane units 54 and 55 by making cuts on them. These convex units are formed in such a manner that they face each other, and form a trapezoid whose width becomes smaller as the distance on the trapezoid to the bottom decreases.
In each of these convex units, the bottom side is folded to the side of the article 100 (concave folds V for the convex units of the pair of suspending units 52 and 53, and convex folds M for the convex units of the pair of side plane units 54 and 55), and along the remaining two lines, cuts are made (cut lines C). Thereby, the convex units 54b, 54c, 55b, and 55c of the pair of side plane units 54 and 55 are engaged with the suspending units 52 and 53. Additionally, it is also possible to form through holes instead of forming the convex units 52d, 52e, 53d, and 53e on the side of the pair of suspending units 52 and 53 in order to achieve the above engagement.
As illustrated in
The article 100 is held on the article mounting plane unit 51 by, for example, two belt units 58 illustrated in
The suspending units 52 and 53 according to the present embodiment also include through holes 52a and 53a, small width units 52b and 53b, and large width units 52c and 53c similar to those in the first embodiment.
The pair of side plane units 54 and 55 according to the present embodiment also include through holes 54a and 55a similar to those in the first embodiment.
The pair of downward-bent units 56 and 57 according to the present embodiment also include main body units 56a and 57a, left-hand side triangle units 56b and 57b, right-hand side triangle units 56c and 57c, left end units 56d and 57d, and right end units 56e and 57e similar to those in the first embodiment.
Also in the above third embodiment, the same effect as that of the first embodiment can be achieved, i.e., the enhancement of the shock absorbing ability of the packaging box 3 with a simple configuration and the like.
Further, in the present embodiment, convex units (examples of engagement units) 54b, 54c, 55b, and 55c that are engaged with the pair of suspending units 52 and 53 are formed on the pair of side plane units 54 and 55. These convex units are formed by making cuts on the pair of side plane units 54 and 55 (cut lines C). Accordingly, the pair of suspending units 52 and 53 and the pair of side plane units 54 and 55 can be positioned with a simple configuration.
Also, in the present embodiment, the partition unit 59 that partitions the space above the article mounting plane unit 51 into the upper space and the lower space is set on the convex units 54b, 54c, 55b, and 55c of the pair of side plane units 54 and 55. This makes it possible to utilize space efficiently.
Also, in the present embodiment, the belt insertion slots 56f, 56g, 57f, and 57g are formed on the pair of downward-bent units 56 and 57. The belts 58a of the belt units 58 to hold the article 100 on the article mounting plane unit 51 are inserted into these belt insertion slots 56f, 56g, 57f, and 57g. This makes it possible to hold the article 100 securely.
Fourth EmbodimentThe packaging box 4 according to the present embodiment is different from the first embodiment in that it omits the supporting unit 30, and includes a pair of suspending units 62 and 63, a pair of side plane units 64 and 65, and insertion slots 21c and 23c on an exterior unit 20-1. The present embodiment is similar to the first embodiment in the other aspects, and thus explanations thereof will be omitted.
A packaging component 60 of the packaging box 4 illustrated in
The exterior unit 20-1 according to the present embodiment is different from the exterior unit 20 of the first embodiment in that the exterior unit 20-1 includes the insertion slots 21c and 23c on a left plane unit 21-1 and a right plane unit 23-1 (examples of two opposing walls). The insertion slots 21c and 23c will be explained later.

The side plane unit 65 on the right side is inserted from above into the insertion slot 23c. This side plane unit 65 is inserted into the insertion slot 23c so as to be in surface contact with the outer surface unit 23a-1 (and the inner surface unit 23b-1) of the right plane unit 23-1.
The insertion slot 21c of the left plane unit 21-1 is formed in such a manner that the side plane unit 64 on the left side is inserted from above into the insertion slot 21c similarly to the insertion slot 23c of the right plane unit 23-1.
The pair of suspending units 62 and 63 includes oblique plane units 62f and 63f that are continuous to the article mounting plane unit 61, and horizontal plane units 62g and 63g that are continuous to the pair of side plane units 64 and 65. Also, the horizontal plane units 62g and 63g of the suspending units 62 and 63 are set on inner surface units 21b-1 and 23b-1 of the left plane unit 21-1 or the right plane unit 23-1.
The width of the pair of side plane units 64 and 65 is identical or almost identical (a few millimeters smaller for example) to that of the insertion slots 21c and 23c of the exterior unit 20-1. The height of the pair of side plane units 64 and 65 is smaller than the inner dimension of the exterior unit 20-1, and does not abut the bottom plane unit 26 of the exterior unit 20-1. It is also possible for the pair of side plane units 64 and 65 to abut the bottom plane unit 26 of the exterior unit 20-1 similarly to the first embodiment.
The horizontal plane units 62g and 63g of the pair of suspending units 62 and 63 are held between the top plane unit 25 and the inner surface units 21b-1 and 23b-1 of the exterior unit 20-1. Accordingly, when the area over which the horizontal plane units 62g and 63g of the suspending units 62 and 63 are pressed by the top plane unit 25 is increased, the anchorage strength of the pair of side plane units 64 and 65 also increases.
Also in the above fourth embodiment, the same effect as that of the first embodiment can be achieved, i.e., the enhancement of the shock absorbing ability of the packaging box 4 with a simple configuration and the like.
Further, in the present embodiment, the insertion slots 21c and 23c into which the pair of side plane units 64 and 65 are inserted from above are formed on the left plane unit 21-1 and the right plane unit 23-1 (two opposing walls) of the exterior unit 20-1. Also, the pair of side plane units 64 and 65 are inserted into the insertion slots 21c and 23c so as to be in surface contact with the left plane unit 21-1 or the right plane unit 23-1. Accordingly, it is possible to assure that the pair of side plane units 64 and 65 in surface are kept in contact with the left plane unit 21-1 or the right plane unit 23-1 of the exterior unit 20-1.
Fifth EmbodimentThe packaging box 5 according to the present embodiment is different from the first embodiment in that the packaging box 5 contains a point at which a pair of downward-bent units 76 and 77 cross each other at their end points, and also in that the packaging box 5 omits the supporting unit 30. The present embodiment is similar to the first embodiment in the other aspects, and thus explanations thereof will be omitted.

As illustrated in
The pair of downward-bent units 76 and 77 cross each other at the concavo-convex units 76g and 77g, and are in contact with the bottom plane unit 26 of the exterior unit 20. Similarly to the above first embodiment, it is also possible to provide interspaces between the bottom plane unit 26 and the pair of downward-bent units 76 and 77 (concavo-convex units 76g and 77g) so that they do not touch each other.
The suspending units 72 and 73 according to the present embodiment also include through holes 72a and 73a, small width units 72b and 73b, and large width units 72c and 73c similar to those in the first embodiment.
The pair of side plane units 74 and 75 according to the present embodiment also include through holes 74a and 75a similar to those in the first embodiment.
The pair of downward-bent units 76 and 77 according to the present embodiment also include main body units 76a and 77a, left-hand side triangle units 76b and 77b, right-hand side triangle units 76c and 77c, left end units 76d and 77d, and right end units 76e and 77e similar to those in the first embodiment.
Also in the above fifth embodiment, the same effect as that of the first embodiment can be achieved, i.e. the enhancement of the shock absorbing ability of the packaging box with a simple configuration and the like.
Further, in the present embodiment, the pair of downward-bent units 76 and 77 cross each other at the lower end side. Accordingly, the pair of downward-bent units 76 and 77 form a truss structure together with the triangular portions above and below the crossing point so as to enhance the shock absorbing ability of the packaging box 5.
Also, the concavo-convex units 76g and 77g are formed on the lower ends of the pair of downward-bent units 76 and 77, and the pair of downward-bent units 76 and 77 cross each other at the concavo-convex units 76g and 77g. This leads to further enhancement of the shock absorbing ability of the packaging box 5 with a simple configuration.
Additionally, even when the concavo-convex units 76g and 77g at the lower ends of the downward-bent units 76 and 77 are omitted, it is possible for the pair of downward-bent units 76 and 77 to cross each other by, for example, inserting one of the downward-bent units 76 and 77 into a slot provided on the other of the downward-bent units 76 and 77.
