In Patent Literature 1, one corrugated cardboard sheet is folded, and the folded corrugated cardboard sheet surrounds the package. The package is stored in a case while being surrounded by cardboard sheets.

特開２０１７－１７８３８５号公報JP 2017-178385 A

たとえば、互いに独立した複数の緩衝部材が緩衝材として梱包物と共にケースに収納される。複数の緩衝部材は、それぞれ、梱包物に接触し、梱包物を保護する。複数の緩衝部材は、それぞれ、梱包物の異なる箇所を保護する。収納ケース内に複数の緩衝部材を配置しておくことにより、収納ケースが落下などしても、梱包物への衝撃を緩衝できる。 For example, a plurality of mutually independent cushioning members are housed in the case together with the package as cushioning materials. Each of the plurality of cushioning members contacts the package and protects the package. A plurality of cushioning members respectively protect different parts of the package. By arranging a plurality of cushioning members in the storage case, even if the storage case is dropped, it is possible to cushion the impact on the package.

ここで、収納ケースが落下などすると、いずれかの緩衝部材が変形する場合がある。緩衝部材は、変形することにより、梱包物への衝撃を緩衝する。しかし、いずれかの緩衝部材が変形した場合、変形した緩衝部材にガタが生じる。そして、変形した緩衝部材の配置位置が初期位置からずれる場合がある。 Here, if the storage case is dropped or the like, one of the cushioning members may be deformed. The cushioning member cushions the impact on the package by deforming. However, when one of the cushioning members is deformed, the deformed cushioning member rattles. Then, the arrangement position of the deformed cushioning member may deviate from the initial position.

いずれかの緩衝部材に位置ずれが生じると、位置ずれした緩衝部材によって本来保護すべき個所を保護できなくなる。その状態で収納ケースに衝撃が加わった場合には、梱包物の保護が十分ではないので、梱包物が破損するという不都合が生じ得る。 If any of the cushioning members is misaligned, the location that should be protected cannot be protected by the misaligned cushioning member. If an impact is applied to the storage case in this state, the package may be damaged because the package is not sufficiently protected.

本発明は、上記課題を解決するためになされたものであり、緩衝部材の位置ずれを抑制することが可能な梱包部材を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a packing member capable of suppressing displacement of a cushioning member.

上記目的を達成するため、本発明の一局面による梱包部材は、梱包物を収納する収納ケースと、収納ケースの内部において、梱包物を囲うように配置される複数の緩衝部材と、を備え、複数の緩衝部材は、それぞれ、係合部を有し、複数の緩衝部材は、それぞれ、係合部を介して、他の緩衝部材と連結する。 In order to achieve the above object, a packaging member according to one aspect of the present invention comprises a storage case for storing a package, and a plurality of cushioning members arranged inside the storage case so as to surround the package, Each of the plurality of cushioning members has an engaging portion, and each of the plurality of cushioning members is connected to another cushioning member via the engaging portion.

本発明の構成では、緩衝部材の位置ずれを抑制できる。 With the configuration of the present invention, displacement of the cushioning member can be suppressed.

以下、図１～図２１を参照し、本実施形態の梱包部材１００について説明する。以下の説明では、図中のＸ方向を左右方向（「水平方向」に相当）と定義し、Ｙ方向を前後方向と定義し、Ｚ方向を上下方向と定義する。 The packing member 100 of this embodiment will be described below with reference to FIGS. 1 to 21. FIG. In the following description, the X direction in the drawings is defined as the left-right direction (corresponding to the "horizontal direction"), the Y direction is defined as the front-back direction, and the Z direction is defined as the up-down direction.

梱包部材１００は、図１に示すように、収納ケース２００を備える。収納ケース２００には、梱包物３００が収納される。梱包物３００は、たとえば、プリンターである。 The packing member 100 includes a storage case 200 as shown in FIG. A package 300 is stored in the storage case 200 . Package 300 is, for example, a printer.

また、梱包部材１００は、図１～図３に示すように、互いに独立した複数の緩衝部材１０を備える。すなわち、複数の緩衝部材１０は、それぞれ、他の緩衝部材１０とは別部材である。複数の緩衝部材１０は、それぞれ、紙製である。複数の緩衝部材１０は、収納ケース２００の内部に配置される。複数の緩衝部材１０は、収納ケース２００の内部において、梱包物３００を保護する。 1 to 3, the packing member 100 includes a plurality of cushioning members 10 independent of each other. That is, each of the multiple cushioning members 10 is a separate member from the other cushioning members 10 . Each of the multiple cushioning members 10 is made of paper. A plurality of cushioning members 10 are arranged inside the storage case 200 . A plurality of cushioning members 10 protect the package 300 inside the storage case 200 .

収納ケース２００は、たとえば、段ボールシートで形成される。収納ケース２００は、上下方向の上側に開口２００Ａを有する。複数の緩衝部材１０は、開口２００Ａを介して、収納ケース２００に対して出し入れされる。すなわち、収納ケース２００に対する緩衝部材１０の出し入れ方向は上下方向である。梱包物３００も同様に、開口２００Ａを介して、収納ケース２００に対して出し入れされる。 Storage case 200 is formed of, for example, a cardboard sheet. The storage case 200 has an opening 200A on the upper side in the vertical direction. A plurality of cushioning members 10 are taken in and out of the storage case 200 through the opening 200A. That is, the direction in which the cushioning member 10 is taken in and out of the storage case 200 is the vertical direction. Similarly, the package 300 is put in and taken out of the storage case 200 through the opening 200A.

図示しないが、梱包物３００の収納後、開口２００Ａは、収納ケース２００の本体に一体的に形成されるフラップによって塞がれる。梱包物３００の収納後、開口２００Ａは、収納ケース２００の本体とは別体の蓋部材によって塞がれてもよい。梱包物３００を出し入れするとき、開口２００Ａが開放される。 Although not shown, the opening 200A is closed by a flap formed integrally with the main body of the storage case 200 after the package 300 is stored. After storing the package 300 , the opening 200</b>A may be closed by a lid member separate from the main body of the storage case 200 . When the package 300 is put in and taken out, the opening 200A is opened.

また、緩衝部材１０の個数は７個である。なお、梱包部材１００を構成する緩衝部材１０の個数は特に限定されず、７個未満であってもよいし、８個以上であってもよい。以下の説明では、複数の緩衝部材１０にそれぞれ符号１～７を付して区別する場合がある。 Also, the number of buffer members 10 is seven. The number of cushioning members 10 constituting the packing member 100 is not particularly limited, and may be less than seven or may be eight or more. In the following description, the plurality of cushioning members 10 may be distinguished from each other by attaching reference numerals 1 to 7, respectively.

複数の緩衝部材１０は、収納ケース２００の内部において、梱包物３００を囲うように配置される。複数の緩衝部材１０は、収納ケース２００の内面と梱包物３００との間に配置され、梱包物３００に接触する。複数の緩衝部材１０は、収納ケース２００の内部において、梱包物３００が動かないように支持する。 A plurality of cushioning members 10 are arranged inside storage case 200 so as to surround package 300 . A plurality of cushioning members 10 are arranged between the inner surface of the storage case 200 and the package 300 and come into contact with the package 300 . The plurality of cushioning members 10 support the package 300 so that it does not move inside the storage case 200 .

複数の緩衝部材１０のうち２つは、収納ケース２００の内部において、上下方向の下側に配置される。以下、収納ケース２００内の下側に配置される２つの緩衝部材１０にそれぞれ符号１および２を付し、他の緩衝部材１０と区別する。緩衝部材１の単独図を図４に示し、緩衝部材２の単独図を図５に示す。 Two of the plurality of cushioning members 10 are arranged on the lower side in the vertical direction inside the storage case 200 . Hereinafter, the two cushioning members 10 arranged on the lower side in the storage case 200 are denoted by reference numerals 1 and 2, respectively, to distinguish them from the other cushioning members 10.

また、緩衝部材５と緩衝部材６とが連結（係合）される。緩衝部材５と緩衝部材６との位置決め構造を図１７および図１８に示す。以下の説明では、係合部Ｅを区別する必要がある場合、緩衝部材６と係合する緩衝部材５の係合部Ｅに符号Ｅ５２を付す。係合部Ｅ５２と係合する緩衝部材６の係合部Ｅに符号Ｅ６２を付す。 Also, the cushioning member 5 and the cushioning member 6 are connected (engaged). 17 and 18 show the positioning structure of the cushioning member 5 and the cushioning member 6. FIG. In the following description, when it is necessary to distinguish the engaging portion E, the engaging portion E of the cushioning member 5 that engages with the cushioning member 6 is denoted by E52. The engagement portion E of the cushioning member 6 that engages with the engagement portion E52 is denoted by E62.

係合部Ｅ５２は、係合孔である。係合部Ｅ６２は、係合突起である。係合部Ｅ５２は、２つであり、中空部分５１１および５２１のそれぞれの上下方向の上側部分（上端）である。言い換えると、係合部Ｅ５２は、中空部分５１１および５２１のそれぞれの上端の孔部（開口）である。係合部Ｅ６２は、２つであり、中空部分６１および６２のそれぞれの上下方向の下側部分である（図１０参照）。 The engaging portion E52 is an engaging hole. The engaging portion E62 is an engaging projection. There are two engaging portions E52, which are upper portions (upper ends) of the hollow portions 511 and 521 in the vertical direction. In other words, the engaging portion E52 is a hole (opening) at the upper end of each of the hollow portions 511 and 521 . There are two engaging portions E62, which are vertically lower portions of the hollow portions 61 and 62 (see FIG. 10).

これにより、収納ケース２００内に緩衝部材５を先に配置した後、緩衝部材５に対して緩衝部材６を上方から重ねるように配置することにより、緩衝部材５の中空部分５１１および５２１の各筒内（すなわち、係合孔）に緩衝部材６の中空部分６１および中空部分６２の各下側部分（すなわち、係合突起）が挿入される。その結果、緩衝部材５と緩衝部材６とが連結される。 As a result, after placing the cushioning member 5 in the storage case 200 first, by placing the cushioning member 6 over the cushioning member 5 from above, each cylinder of the hollow portions 511 and 521 of the cushioning member 5 is arranged. Each lower portion (ie, engagement protrusion) of the hollow portion 61 and the hollow portion 62 of the cushioning member 6 is inserted inside (ie, engagement hole). As a result, the cushioning member 5 and the cushioning member 6 are connected.

なお、緩衝部材６は、緩衝部材５の上方に隣接して配置される。すなわち、緩衝部材５および６に着目した場合、緩衝部材５が「第１緩衝部材」に相当する部材となり、緩衝部材６が「第２緩衝部材」に相当する部材となる。 In addition, the cushioning member 6 is arranged above and adjacent to the cushioning member 5 . That is, when focusing on the cushioning members 5 and 6, the cushioning member 5 is a member corresponding to the "first cushioning member", and the cushioning member 6 is a member corresponding to the "second cushioning member".

また、緩衝部材５と緩衝部材７とが連結（係合）される。緩衝部材５と緩衝部材７との位置決め構造を図１９および図２０に示す。以下の説明では、係合部Ｅを区別する必要がある場合、緩衝部材７と係合する緩衝部材５の係合部Ｅに符号Ｅ５３を付す。係合部Ｅ５３と係合する緩衝部材７の係合部Ｅに符号Ｅ７２を付す。 Also, the cushioning member 5 and the cushioning member 7 are connected (engaged). 19 and 20 show the positioning structure of the cushioning member 5 and the cushioning member 7. FIG. In the following description, when it is necessary to distinguish the engaging portion E, the engaging portion E of the cushioning member 5 that engages with the cushioning member 7 is denoted by E53. The engagement portion E of the cushioning member 7 that engages with the engagement portion E53 is denoted by E72.

係合部Ｅ５３は、２つである。一方の係合部Ｅ５３は、左側の板状部５０１に対し上側から切り込まれたスリットである。他方の係合部Ｅ５３は、右側の板状部５０２に対し上側から切り込まれたスリットである。板状部５０１および５０２は、係合部Ｅ５３を後側に有する。 There are two engaging portions E53. One engaging portion E53 is a slit cut into the plate-like portion 501 on the left side from above. The other engaging portion E53 is a slit cut into the plate-like portion 502 on the right side from above. Plate-like portions 501 and 502 have an engaging portion E53 on the rear side.

係合部Ｅ７２は、上下方向からの平面視において板状部５０１および５０２と交差（直交を含む）するＸＺ平面に平行な板状部に対し下側から切り込まれたスリットである。係合部Ｅ７２は、左側および右側に１つずつ形成される。言い換えると、左側の係合部Ｅ７２は、板状部５０１の係合部Ｅ５３と上下方向に重なる箇所（交わる個所）に配置され、右側の係合部Ｅ７２は、板状部５０２の係合部Ｅ５３と上下方向に重なる箇所（交わる箇所）に配置される。 The engaging portion E72 is a slit cut from below in a plate-like portion parallel to the XZ plane that intersects (including orthogonally) the plate-like portions 501 and 502 in plan view from above and below. One engaging portion E72 is formed on the left side and one on the right side. In other words, the left engaging portion E72 is arranged at a position that overlaps (intersects) with the engaging portion E53 of the plate-like portion 501 in the vertical direction, and the right engaging portion E72 is arranged at the engaging portion of the plate-like portion 502 It is arranged at a place where it overlaps (intersects) with E53 in the vertical direction.

これにより、先に収納ケース２００内に緩衝部材５を配置した後、緩衝部材５に対して緩衝部材７を上方から重ねるように配置することにより、係合部Ｅ５３と係合部Ｅ７２とが係合し、緩衝部材５と緩衝部材７とが連結する。 As a result, after first disposing the cushioning member 5 in the storage case 200, by arranging the cushioning member 7 so as to overlap the cushioning member 5 from above, the engaging portion E53 and the engaging portion E72 are engaged. Then, the cushioning member 5 and the cushioning member 7 are connected.

なお、係合部Ｅ５３およびＥ７２の各構成は特に限定されない。係合部Ｅ５３を係合突起とし、係合部Ｅ７２を係合孔としてもよい。また、係合部Ｅ５３を係合孔とし、係合部Ｅ７２を係合突起としてもよい。 In addition, each configuration of the engaging portions E53 and E72 is not particularly limited. The engaging portion E53 may be an engaging protrusion and the engaging portion E72 may be an engaging hole. Alternatively, the engaging portion E53 may be an engaging hole, and the engaging portion E72 may be an engaging projection.

係合部Ｅ５２と係合部Ｅ６２とが係合し、係合部Ｅ５３と係合部Ｅ７２とが係合することにより、緩衝部材５～７が互いに位置決めされる。これにより、緩衝部材５～７がＸＹ平面に平行な方向（上下方向と直交する水平方向）に動かないように保持される。 The engagement portion E52 and the engagement portion E62 are engaged, and the engagement portion E53 and the engagement portion E72 are engaged, whereby the cushioning members 5 to 7 are positioned with respect to each other. As a result, the cushioning members 5 to 7 are held so as not to move in the direction parallel to the XY plane (horizontal direction perpendicular to the vertical direction).

本実施形態では、上記のように、複数の緩衝部材１０（１～７）は、それぞれ、係合部Ｅを有する。そして、複数の緩衝部材１０は、それぞれ、係合部Ｅを介して、隣接する他の緩衝部材１０と連結する。この構成では、いずれかの緩衝部材１０が変形し、変形した緩衝部材１０と梱包物３００との間にガタが生じても、変形した緩衝部材１０は他の緩衝部材１０と連結しているので、変形した緩衝部材１０の配置位置が初期位置からずれることを抑制できる。 In this embodiment, each of the plurality of cushioning members 10 (1 to 7) has the engaging portion E as described above. Each of the multiple cushioning members 10 is connected to another adjacent cushioning member 10 via the engaging portion E. As shown in FIG. With this configuration, even if one of the cushioning members 10 is deformed and looseness occurs between the deformed cushioning member 10 and the package 300, the deformed cushioning member 10 is connected to the other cushioning member 10. , the disposition position of the deformed cushioning member 10 can be suppressed from deviating from the initial position.

変形した緩衝部材１０の位置ずれが抑制されることにより、保護対象の梱包物３００のうち、変形した緩衝部材１０が本来保護すべき個所が十分に保護されないという不都合を抑制できる。したがって、次に収納ケース２００に衝撃が加わったとき、梱包物３００が破損することを抑制できる。 By suppressing the displacement of the deformed cushioning member 10, it is possible to suppress the problem that the portion of the package 300 to be protected, which should be protected by the deformed cushioning member 10, is not sufficiently protected. Therefore, when the next impact is applied to the storage case 200, damage to the package 300 can be suppressed.

また、本実施形態では、上記のように、先に収納ケース２００の内部に配置される緩衝部材１０（「第１緩衝部材」に相当）に対し、その次に収納ケース２００の内部に配置すべき緩衝部材１０（「第２緩衝部材」に相当）を上方から重ねるように配置することにより、係合孔に係合突起が挿入され、第１緩衝部材と第２緩衝部材とが連結される。この構成では、開口２００Ａを介して複数の緩衝部材１０を順番に収納ケース２００内に配置していくだけで、先に配置した緩衝部材１０と次に配置する緩衝部材１０とを連結することができる。その結果、緩衝部材１０同士を連結する作業を別途行う必要がないので、作業性が向上する。 Further, in the present embodiment, as described above, the cushioning member 10 (corresponding to the “first cushioning member”) that is placed inside the storage case 200 first is followed by the cushioning member 10 that is placed inside the storage case 200 next. By arranging the cushioning member 10 (corresponding to the "second cushioning member") to overlap from above, the engagement projection is inserted into the engagement hole, and the first cushioning member and the second cushioning member are connected. . In this configuration, by simply arranging a plurality of cushioning members 10 in order in the storage case 200 through the opening 200A, the previously arranged cushioning member 10 and the next cushioning member 10 can be connected. . As a result, there is no need to separately perform the work of connecting the cushioning members 10 to each other, so workability is improved.

次に、補助機能を有する緩衝部材５について説明する。 Next, the cushioning member 5 having an auxiliary function will be described.

緩衝部材５が補助機能を有する構成では、緩衝部材５が「第３緩衝部材」に相当する部材となる。また、緩衝部材５は、上下方向において、緩衝部材１および２と緩衝部材６および７との間に配置される。そして、緩衝部材５は、係合部Ｅを介して、下方において緩衝部１および２に連結され、上方において緩衝部材６および７に連結される。緩衝部材６および７は、緩衝部材３および４に連結される。 In the configuration in which the cushioning member 5 has an auxiliary function, the cushioning member 5 is a member corresponding to the "third cushioning member". Moreover, the cushioning member 5 is arranged between the cushioning members 1 and 2 and the cushioning members 6 and 7 in the vertical direction. The cushioning member 5 is connected to the cushioning portions 1 and 2 at the bottom and to the cushioning members 6 and 7 at the top through the engagement portion E. As shown in FIG. The damping members 6 and 7 are connected to the damping members 3 and 4 .

これにより、緩衝部材５が補助機能を有する構成では、緩衝部材１および２が「第１緩衝部材」に相当する部材となる。また、緩衝部材６および７が「第２緩衝部材」に相当する部材となる。さらに、緩衝部材３および４は、緩衝部材６および７を介して間接的に、緩衝部材５に連結される。このため、緩衝部材３および４も「第２緩衝部材」に相当する部材である。 Accordingly, in a configuration in which the cushioning member 5 has an auxiliary function, the cushioning members 1 and 2 are members corresponding to the "first cushioning member". Moreover, the cushioning members 6 and 7 are members corresponding to the "second cushioning member". Furthermore, damping members 3 and 4 are indirectly connected to damping member 5 via damping members 6 and 7 . Therefore, the cushioning members 3 and 4 are also members corresponding to the "second cushioning member".

緩衝部材５の一対の側板５０１および５０２は、図９に示したように、それぞれ、接続部ＣＰを支点に、梱包物３００の側面に対して接近する方向および離間する方向に移動可能である。言い換えると、一対の側板５０１および５０２は、それぞれ、接続部ＣＰを支点に、接続部ＣＰとは反対側の端部を振るように移動する。 As shown in FIG. 9, the pair of side plates 501 and 502 of the cushioning member 5 are movable toward and away from the side surface of the package 300 with the connecting portion CP as a fulcrum. In other words, the pair of side plates 501 and 502 each move so as to swing the end opposite to the connection portion CP with the connection portion CP as a fulcrum.

場合によっては、収納ケース２００内に緩衝部材１および２を配置した後、緩衝部材５を梱包物３００に装着した状態で、梱包物３００と共に緩衝部材５が収納ケース２００内に配置される。このとき、左側部５１０および右側部５２０が梱包物３００から離間する方向に移動すると、梱包作業がやり難い。 In some cases, after the cushioning members 1 and 2 are placed in the storage case 200 , the cushioning member 5 is placed in the storage case 200 together with the package 300 with the cushioning member 5 attached to the package 300 . At this time, if the left side portion 510 and the right side portion 520 are moved away from the article to be packed 300, the packing work is difficult.

そこで、本実施形態では、上記のように、左側部５１０は、接続部ＣＰとは反対側の端部に係合部Ｅ５２およびＥ５３を有する。係合部Ｅ５２には、緩衝部材６の係合部Ｅ６２が係合され、係合部Ｅ５３には、緩衝部材７の係合部Ｅ７２が係合される。 Therefore, in this embodiment, as described above, the left side portion 510 has the engaging portions E52 and E53 at the end opposite to the connection portion CP. The engaging portion E62 of the cushioning member 6 is engaged with the engaging portion E52, and the engaging portion E72 of the cushioning member 7 is engaged with the engaging portion E53.

この構成では、一対の側板５０１および５０２が梱包物３００を左右方向（すなわち、上下方向と直交する水平方向）に挟んだ状態で、緩衝部材５の係合部Ｅ５２およびＥ５３がそれぞれ緩衝部材６の係合部Ｅ６２および緩衝部材７の係合部Ｅ７２と係合することにより、一対の側板５０１および５０２が梱包物３００を挟んで左右方向に互いに対向する位置に保持される。すなわち、梱包物３００と共に緩衝部材５を収納ケース２００内に配置するとき、緩衝部材５に対して緩衝部材６および７を係合させることにより、一対の側板５０１および５０２が梱包物３００の側面から離間する方向に移動することを抑制できる。その結果、梱包の作業性が向上する。 In this configuration, the pair of side plates 501 and 502 sandwich the package 300 in the left-right direction (that is, in the horizontal direction perpendicular to the vertical direction), and the engaging portions E52 and E53 of the cushioning member 5 are engaged with the cushioning member 6, respectively. By engaging with the engaging portion E62 and the engaging portion E72 of the cushioning member 7, the pair of side plates 501 and 502 are held at positions facing each other in the left-right direction with the package 300 interposed therebetween. That is, when the cushioning member 5 is placed inside the storage case 200 together with the article 300 to be packed, the pair of side plates 501 and 502 are separated from the sides of the article 300 by engaging the cushioning members 6 and 7 with the cushioning member 5 . It is possible to suppress movement in the separating direction. As a result, workability of packing is improved.

また、この構成では、梱包部材１００を開梱し、梱包物３００を収納ケース２００の上方から取り出す際、緩衝部材３および４を取り出した後、一対の側板５０１および５０２を把持して、梱包物３００を引き上げることができる。これにより、梱包物３００を取り出すときの作業性が向上する。 Further, in this configuration, when unpacking the packing member 100 and taking out the package 300 from above the storage case 200, after removing the cushioning members 3 and 4, the pair of side plates 501 and 502 are gripped and the package is taken out. 300 can be raised. This improves workability when taking out the package 300 .

また、一対の側板５０１および５０２には、それぞれ、上部に取っ手部５００が形成される。一対の側板５０１および５０２の各取っ手部５００は、板厚方向に貫通する開口である。 Also, the pair of side plates 501 and 502 are each formed with a handle portion 500 at the upper portion thereof. Each handle portion 500 of the pair of side plates 501 and 502 is an opening passing through in the plate thickness direction.

ここで、梱包物３００の引き上げ後、緩衝部材５（すなわち、第３緩衝部材）と緩衝部材６および７（しなわち、第２緩衝部材）との係合が解除される。緩衝部材５と緩衝部材６および７との係合が解除されることにより、図２１に示すように、一対の側板５０１および５０２は、底板５０との接続部ＣＰ（図９参照）を支点に、梱包物３００の側面から離間する方向に開く。そして、取っ手部５００を把持可能となる。その結果、梱包物３００の持ち運びが容易となる。 Here, after the package 300 is pulled up, the engagement between the cushioning member 5 (that is, the third cushioning member) and the cushioning members 6 and 7 (that is, the second cushioning members) is released. By releasing the engagement between the cushioning member 5 and the cushioning members 6 and 7, the pair of side plates 501 and 502 move around the joint CP (see FIG. 9) with the bottom plate 50 as shown in FIG. , open in a direction away from the side surface of the package 300 . Then, the handle portion 500 can be gripped. As a result, the carrying of the package 300 becomes easy.

また、梱包物３００の開封作業において、緩衝部材６および７を緩衝部材５から取り外すだけで、緩衝部材５に対して梱包物３００を開封できる。すなわち、緩衝部材５を切断するなどの作業を別途行わなくてもよい。その結果、作業者の利便性が向上する。 Further, in the work of opening the package 300 , the package 300 can be opened from the cushioning member 5 simply by removing the cushioning members 6 and 7 from the cushioning member 5 . That is, there is no need to separately perform work such as cutting the cushioning member 5 . As a result, convenience for workers is improved.

今回開示された実施形態は、すべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、上記実施形態の説明ではなく特許請求の範囲によって示され、さらに、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 The embodiments disclosed this time should be considered illustrative in all respects and not restrictive.
