20230141442
The present application is based on, and claims priority from JP Application Serial Number 2021-182458, filed Nov. 9, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a cushioning material, a packing material, and packed goods.
A cushioning material for being put into a packing box configured for encasement of electronic equipment so as to absorb external stress applied to the electronic equipment is known. For example, JP-A-2018-131268 discloses a technique for absorbing external stress applied to the electronic equipment by means of a cushioning material that includes two plate-like members.
However, in related art, the structure is hollow in between the two plate-like members. For this reason, in related art, it could happen that the two plate-like members come into contact with each other when the cushioning material is under external stress, resulting in failing to absorb the external stress.
Provided by a certain aspect of the present disclosure is a cushioning material for being put into a packing box configured for encasement of electronic equipment, the cushioning material being configured to absorb external stress applied to the electronic equipment encased in the packing box, the cushioning material comprising: a first holder including a first plate configured to face the electronic equipment when the cushioning material and the electronic equipment are encased in the packing box, and a second plate configured to face an inner wall surface of the packing box when the cushioning material and the electronic equipment are encased in the packing box; and a first cushioning block provided between the first plate and the second plate.
Also provided by a certain aspect of the present disclosure is a packing material, comprising: a packing box configured for encasement of electronic equipment; and a cushioning material for being put into the packing box and configured to absorb external stress applied to the electronic equipment encased in the packing box, the cushioning material including a first holder including a first plate configured to face the electronic equipment when the cushioning material and the electronic equipment are encased in the packing box, and a second plate configured to face an inner wall surface of the packing box when the cushioning material and the electronic equipment are encased in the packing box; and a first cushioning block provided between the first plate and the second plate.

As illustrated in
The cushioning block R1 is held by the holder H1 between the holder plate P1 and the holder plate P2. In the present embodiment, a case where the cushioning block R1 is held by the holder H1 by bonding the −Zs-side end of the cushioning block R1 to the holder plate P1 by means of adhesive and by bonding the +Zs-side end of the cushioning block R1 to the holder plate P2 by means of adhesive is assumed as an example.

In the present embodiment, it is assumed that the cushioning block R is made of a material having lower elasticity than styrene foam.
In the present embodiment, the following case is assumed as an example: fibers contained in a matter/material are obtained by defibrating the matter/material such as paper, clothes, or the like containing various kinds of fibers such as animal-based fibers, plant-based fibers, chemical fibers, or the like, and then the obtained fibers are processed, thereby forming the cushioning blocks R. More specifically, in the present embodiment, it is assumed that fibers contained in paper are obtained by defibrating the paper, and then the obtained fibers are hardened, thereby forming the cushioning blocks R.
As described above, in the present embodiment, the cushioning blocks R are produced by going through a process of obtaining fibers from a fiber-containing matter/material such as paper, clothes, or the like. That is, in the present embodiment, when a fiber-containing matter/material such as paper, clothes, or the like is thrown away, it is possible to produce the cushioning blocks R by recycling this matter/material. Therefore, the scheme of the present embodiment makes it possible to reduce environmental burdens pertinent to production and disposal of the cushioning blocks R.
In the present embodiment, the holder plate P1, the holder plate P3, and the holder plate P5 face the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. A cavity AN is formed in the holder plate P1, the holder plate P3, and the holder plate P5 at a position that corresponds to each corner of the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. The holder plate P2, the holder plate P4, and the holder plate P6 face inner wall surfaces of the packing box 2 respectively when the cushioning material S and the electronic equipment 100 are encased in the packing box 2.
In the present embodiment, the holder H1 is an example of “a first holder”, and the holder H2 is an example of “a second holder”. In the present embodiment, the holder plate P1 is an example of “a first plate”, the holder plate P2 is an example of “a second plate”, the holder plate P3 is an example of “a third plate”, and the holder plate P4 is an example of “a fourth plate”. In the present embodiment, the cushioning block R1 is an example of “a first cushioning block”, and the cushioning block R2 is an example of “a second cushioning block”. In the present embodiment, the +Zs direction is an example of “a first direction”, and the +Xs direction is an example of “a second direction”.
In the present embodiment, for example, it is assumed that the holders H1, H2, and H3 of the cushioning material S are formed by folding a single flat plate-like member HH illustrated as an example in
As illustrated in
As described above, the holder H1 includes the holder plate P1, the holder plate P2, and the link plate Ps1. The holder H1 further includes the link plate Pc12. As illustrated in
As described above, the holder H2 includes the holder plate P3, the holder plate P4, and the link plate Ps2. As illustrated in
As described above, the holder H3 includes the holder plate P5, the holder plate P6, and the link plate Ps3. As illustrated in
In the present embodiment, the fold line θ13 is a mountain fold line, and those other than the fold line θ13 are valley fold lines. The term “valley fold line” as used herein means a fold line at which the flat plate-like member HH is folded along this fold line toward the near side in
As illustrated in
The flat plate-like member HH is folded along the fold line θ13 in a mountain-folding manner and along the fold lines other than the fold line θ13, specifically, along the fold lines θ11, θ12, θ14, θ21, θ22, θ23, θ31, and θ32, in a valley-folding manner, thereby fitting the protruding portion TK1 into the opening KK1, fitting the protruding portion TK2 into the opening KK2, and fitting the protruding portion TK3 into the opening KK3 and the recessed portion KB3. In addition, the cavity AN is formed of the recessed portions OB1, OB2, OB3 by folding the flat plate-like member HH along the fold lines θ11 to θ32.
When the flat plate-like member HH is folded along the fold lines θ11 to θ32, one end of the cushioning block R1 is bonded to an area Ar1 of the holder plate P1, and the other end of the cushioning block R1 is bonded to an area Ar2 of the holder plate P2, thereby holding the cushioning block R1 by the holder H1. In addition, when the flat plate-like member HH is folded along the fold lines θ11 to θ32, one end of the cushioning block R2 is bonded to an area Ar3 of the holder plate P3, and the other end of the cushioning block R2 is bonded to an area Ar4 of the holder plate P4, thereby holding the cushioning block R2 by the holder H2. In addition, when the flat plate-like member HH is folded along the fold lines θ11 to θ32, one end of the cushioning block R3 is bonded to an area Ar5 of the holder plate P5, and the other end of the cushioning block R3 is bonded to an area Ar6 of the holder plate P6, thereby holding the cushioning block R3 by the holder H3.
As illustrated in
For the purpose of explaining one of the effects of the present embodiment, a cushioning material SW of a packing material 1W according to a referential example will now be considered.
As illustrated in
For example, when external stress is applied to the cushioning block R1 of the cushioning material SW according to the referential example via the packing box 2 or the electronic equipment 100, in some instances positional displacement of one end of the cushioning block R1 could occur.
Then, when the positional displacement of the one end of the cushioning block R1 occurs due to the external stress applied to the cushioning block R1 of the cushioning material SW according to the referential example via the packing box 2 or the electronic equipment 100, it could happen that the other end of the cushioning block R1 fails to follow the positional displacement of the one end of the cushioning block R1. If the other end of the cushioning block R1 fails to follow the positional displacement of the one end of the cushioning block R1, it follows that the other end of the cushioning block R1 is located relatively on the +Xs side or on the −Xs side with respect to the one end of the cushioning block R1. For this reason, when external stress is applied to the cushioning block R1 of the cushioning material SW according to the referential example via the packing box 2 or the electronic equipment 100, there is a possibility that the cushioning block R1 might come off the holder plate P1 or the packing box 2. In the cushioning material SW according to the referential example, also for the cushioning blocks R other than the cushioning block R1, similarly to the cushioning block R1, there is a possibility of coming off the holder plate P1 or the packing box 2 due to external stress applied thereto via the packing box 2 or the electronic equipment 100.
By contrast, in the cushioning material S according to the present embodiment, as described earlier, one end of the cushioning block R1 is bonded to the holder plate P1, the other end of the cushioning block R1 is bonded to the holder plate P2, and the holder plate P1 and the holder plate P2 are linked to each other by the link plate Ps1.
For this reason, in the present embodiment, even when the positional displacement of the one end of the cushioning block R1 occurs due to external stress applied to the cushioning block R1 via the packing box 2 or the electronic equipment 100, the other end of the cushioning block R1 follows the positional displacement of the one end of the cushioning block R1 through the intermediary of the holder plate P1, the link plate Ps1, and the holder plate P2 and thus becomes displaced. Therefore, the present embodiment makes it possible to reduce the risk of coming off of the cushioning block R1 from the holder plate P1 or the holder plate P2, to which the cushioning block R1 is bonded, due to the external stress applied to the packing box 2 or the electronic equipment 100, as compared with the referential example. Similarly, also for the cushioning blocks R other than the cushioning block R1, the present embodiment makes it possible to reduce the risk of coming off of this cushioning block R from the holder H, to which this cushioning block R is bonded, due to the external stress applied to the packing box 2 or the electronic equipment 100, as compared with the referential example.
In the present embodiment, the cushioning block R1 is provided between the holder plate P1 and the holder plate P2. Therefore, as compared with a structure in which the cushioning block R1 is not provided between the holder plate P1 and the holder plate P2, the present embodiment makes it possible to absorb the external stress applied to the electronic equipment 100 more reliably. That is, in the present embodiment, the cushioning block R is provided between the plurality of holder plates P of the holder H. Therefore, as compared with a structure in which the cushioning block R is not provided between the plurality of holder plates P of the holder H, the present embodiment makes it possible to absorb the external stress applied to the electronic equipment 100 more reliably.
In the present embodiment, the link plate Ps1 is provided at an area different from an area where the electronic equipment 100 and the packing box 2 overlap each other when the packing material 1 is viewed in the −Zs direction. More specifically, in the present embodiment, the link plate Ps1 is provided relatively on the +Xs side with respect to the electronic equipment 100 when the packing material 1 is viewed in the −Zs direction. Therefore, in the present embodiment, it is possible to absorb, by the cushioning block R1, external stress applied to the electronic equipment 100 and to prevent the link plate Ps1 from having an influence on the absorption of the external stress applied to the electronic equipment 100. Therefore, in the present embodiment, in order to achieve efficient absorption of the external stress by the cushioning material S, just taking the absorption of the external stress applied to the electronic equipment 100 by the cushioning block R1 into consideration suffices. This makes the design of the cushioning material S easier, as compared with a structure in which the external stress applied to the electronic equipment 100 is absorbed both by the link plate Ps1 and by the cushioning block R1. Similarly, in the present embodiment, the link plate Ps2 is provided relatively on the +Ys side with respect to the electronic equipment 100, the link plate Ps3 is provided relatively on the +Zs side with respect to the electronic equipment 100, and, therefore, the design of the cushioning material S is easier, as compared with a structure in which the external stress applied to the electronic equipment 100 is absorbed both by the link plate Ps and by the cushioning block R.
As described above, the cushioning material S according to the present embodiment is a cushioning material for being put into the packing box 2 configured for encasement of the electronic equipment 100. The cushioning material is configured to absorb external stress applied to the electronic equipment 100 encased in the packing box 2. The cushioning material comprises the holder H1 and the cushioning block R1. The holder H1 includes the holder plate P1 and the holder plate P2. The holder plate P1 is configured to face the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. The holder plate P2 is configured to face an inner wall surface of the packing box 2 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. The cushioning block R1 is provided between the holder plate P1 and the holder plate P2.
Therefore, as compared with a structure in which the cushioning block R1 is not provided between the holder plate P1 and the holder plate P2, the present embodiment makes it possible to absorb the external stress applied to the electronic equipment 100 more reliably.
The cushioning material S according to the present embodiment further comprises the holder H2 and the cushioning block R2. The holder H2 includes the holder plate P3 and the holder plate P4. The holder plate P3 is configured to face the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. The holder plate P4 is configured to face an inner wall surface of the packing box 2 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. The cushioning block R2 is provided between the holder plate P3 and the holder plate P4. The cushioning block R1 extends in the +Zs direction going from the holder plate P1 toward the holder plate P2. The cushioning block R2 extends in the +Xs direction going from the holder plate P3 toward the holder plate P4. The holder H1 and the holder H2 are made of a single flat plate-like member HH.
Therefore, the present embodiment makes it possible to make parts management needed for the manufacturing of the cushioning material S simpler, as compared with a case where the cushioning material S is made up of a plurality of members. Moreover, the present embodiment makes it possible to make the management of waste produced at the time of disposal of the cushioning material S simpler, as compared with a case where the cushioning material S is made up of a plurality of members.
In the cushioning material S according to the present embodiment, the cavity AN is formed in the holder plate P1 and the holder plate P3 at a position that corresponds to one of a plurality of corners of the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2. More specifically, in the cushioning material S according to the present embodiment, the recessed portion OB1 is provided in the holder plate P1, and the recessed portion OB2 is provided in the holder plate P3, such that the cavity AN will be formed at a position that corresponds to one of a plurality of corners of the electronic equipment 100 when the cushioning material S and the electronic equipment 100 are encased in the packing box 2.
Therefore, the present embodiment makes it possible to reduce the risk of damage to the cushioning material S arising from pressure applied to the cushioning material S from the corner of the electronic equipment 100, as compared with a structure in which the cavity AN is not provided in the cushioning material S.
Moreover, the present embodiment makes it possible to reduce the risk of damage, which could be caused by the positional displacement of the holder plate P1 in the +Zs direction or the −Zs direction due to pressure applied to the holder plate P1 from the electronic equipment 100 or the cushioning block R1, to the holder plate P1 or the holder plate P3 at the contact portion of the holder plate P1 and the holder plate P3, as compared with a structure in which the cavity AN is not provided in the cushioning material S. Furthermore, the present embodiment makes it possible to reduce the risk of damage, which could be caused by the positional displacement of the holder plate P3 in the +Xs direction or the −Xs direction due to pressure applied to the holder plate P3 from the electronic equipment 100 or the cushioning block R2, to the holder plate P1 or the holder plate P3 at the contact portion of the holder plate P1 and the holder plate P3, as compared with a structure in which the cavity AN is not provided in the cushioning material S.
The exemplary embodiment described above can be modified in various ways. Some specific examples of modification are described below. Any two or more modification examples selected from among the examples described below may be combined as long as they are not contradictory to each other or one another. In each modification example described below, the same reference numerals as those used in the description and illustration of the foregoing embodiment will be assigned to elements that are equivalent to those in the foregoing embodiment in terms of operation and/or function, and a detailed explanation of them is omitted.
In the exemplary embodiment described above, the cushioning block R is fixed to the holder H by means of adhesive. However, the scope of the present disclosure is not limited to such an exemplary structure. The cushioning block R may be fixed to the holder H without using any adhesive.
The cushioning material SA is different from the cushioning material S according to the exemplary embodiment in that it includes a plurality of holders HA in place of the plurality of holders H and in that it includes a plurality of cushioning blocks RA in place of the plurality of cushioning blocks R. More specifically, the cushioning material SA is different from the cushioning material S according to the exemplary embodiment in that it includes three holders HA1, HA2, and HA3 in place of the three holders H1, H2, and H3 and in that it includes three cushioning blocks RA1, RA2, and RA3 in place of the three cushioning blocks R1, R2, and R3.
The holder HA is different from the holder H according to the exemplary embodiment in that it includes two arrangement plates BB between two holder plates P of the holder HA. The arrangement plate BB has an opening HK for insertion of an end portion of the cushioning block RA.
One end of the cushioning block RA is inserted into the opening HK provided in one of the two arrangement plates BB disposed between the two holder plates P of the holder HA. The other end of the cushioning block RA is inserted into the opening HK provided in the other arrangement plate BB. By this means, the cushioning block RA is fixed between the two holder plates P of the holder HA due to a frictional force produced between the opening HK provided in the one of the two arrangement plates BB, which are disposed between the two holder plates P of the holder HA, and the one end of the cushioning block RA, and due to a frictional force produced between the opening HK provided in the other arrangement plate BB and the other end of the cushioning block RA.
For example, as illustrated in
The cushioning block RA is comprised of a plurality of cushioning sheets SS “stacked” in a direction going from the one end toward the other end of the cushioning block RA. Therefore, arranging the cushioning block RA between the two holder plates P of the holder HA makes it possible to absorb external stress applied to the holder HA effectively between the two holder plates P of the holder HA.
For example, as illustrated in
As explained above, in the present modification example, the cushioning block RA is mounted on the holder HA without using any adhesive. Therefore, the present modification example makes it possible to make the burden of detaching the cushioning block RA from the holder HA lighter when the cushioning material SA is taken apart, as compared with a structure in which the cushioning block RA is mounted on the holder HA by means of adhesive. Moreover, the present modification example realizes easy perfect removal of the cushioning block RA from the holder HA when the cushioning material SA is taken apart. Therefore, the present modification example makes it possible to make the recyclability of the cushioning material SA higher than that of the structure in which the cushioning block RA is mounted on the holder HA by means of adhesive.
In the cushioning material SA according to the present modification example, the cushioning block RA1 includes the plurality of cushioning sheets SS stacked in the +Zs direction going from the holder plate P1 toward the holder plate P2.
Therefore, the present modification example makes it possible to absorb +Zs-directional external stress applied to the holder plate P1 or the holder plate P2 and −Zs-directional external stress applied thereto more effectively, as compared with a structure in which the cushioning material SA does not include the cushioning block RA1.
In the cushioning material SA according to the present modification example, the holder HA1 includes the arrangement plate BB1 continuous at one end to the holder plate P1 and disposed between the holder plate P1 and the holder plate P2, and the arrangement plate BB2 continuous at one end to the holder plate P2 and disposed between the holder plate P1 and the holder plate P2. In addition, one end of the cushioning block RA1 is inserted into the opening HK1 provided in the arrangement plate BB1, and the other end of the cushioning block RA1 is inserted into the opening HK2 provided in the arrangement plate BB2.
Therefore, the present modification example makes it possible to fix the cushioning block RA1 between the holder plate P1 and the holder plate P2 of the holder HA1 by utilizing a frictional force produced between the one end of the cushioning block RA1 and the opening HK1 and a frictional force produced between the other end of the cushioning block RA1 and the opening HK2.
In the present modification example, the cushioning block RA is comprised of a plurality of cushioning sheets SS stacked in a direction going from one toward the other of two holder plates P between which this cushioning block RA is held. However, the scope of the present disclosure is not limited to such an exemplary structure. The cushioning block RA may be comprised of a plurality of cushioning sheets SS stacked in a direction intersecting with the direction going from one toward the other of two holder plates P between which this cushioning block RA is held.
Though the cushioning block RA is mounted on the holder HA by utilizing frictional forces without using any adhesive in the present modification example, the scope of the present disclosure is not limited to such an exemplary structure. For example, the cushioning block RA may be mounted on the holder HA more firmly by using adhesive in addition to frictional forces.
In the exemplary embodiment and the modification example 1 described above, a case where the plurality of holders H of the cushioning material S are made of a single flat plate-like member HH has been taken as an example. However, the scope of the present disclosure is not limited to such an exemplary structure. The cushioning material S may be comprised of a plurality of members.
