Description

本発明は、被梱包物の荷重を複数の受け材で受ける梱包材から被梱包物を好適に保護することができる保護部材およびこれを用いた梱包材に関する。   The present invention relates to a protective member capable of suitably protecting a packaged article from a packaging material that receives a load of the packaged article with a plurality of receiving materials, and a packaging material using the same.

従来から、動力機器や精密機器等の被梱包物（重量物）を梱包する際には、その底部を含む全体形状が複雑であるため、梱包材は、被梱包物の底部を部分的に支持する構造となっている。このような梱包材として、図７に示すような梱包材２０が一般的に利用されており、梱包材２０は、被梱包物Ｗの荷重に対して剛性を確保するため金属製となっている。   Conventionally, when packing objects (heavy objects) such as power equipment and precision equipment, since the overall shape including the bottom is complicated, the packing material partially supports the bottom of the object to be packed It has a structure to do. As such a packing material, a packing material 20 as shown in FIG. 7 is generally used, and the packing material 20 is made of metal in order to ensure rigidity against the load of the article to be packed W. .

梱包材２０は、被梱包物Ｗの荷重を受ける４つの金属支柱（受け材）２１と、金属支柱２１を支持する金属基台２２と、を備えている。金属支柱２１は円柱状であり、各金属支柱２１は、その端面２１ａで被梱包物Ｗの底部Ｗｂを支承することができる位置に、配設されている。また、金属支柱２１の端面２１ａには、被梱包物Ｗの載置時に、ウレタンゴム等の緩衝材を載置することもある。   The packing material 20 includes four metal struts (receiving materials) 21 that receive the load of the article to be packed W, and a metal base 22 that supports the metal struts 21. The metal columns 21 are cylindrical, and each metal column 21 is disposed at a position where the bottom surface Wb of the article W to be packed can be supported by the end surface 21a. Further, a cushioning material such as urethane rubber may be placed on the end surface 21a of the metal column 21 when the article to be packed W is placed.

また、別の態様として、被梱包物としてエンジンを梱包する梱包材が提案されている。この梱包材は、エンジンを支承する金属製の支承装置（受け材）と、該支承装置を支持する金属製のパレット基台とを備えている。支承装置は、板状の支持枠体（支持板）をパレット基台から立設させ、支持枠体の端部となるフランジ部には、エンジンを支承する金属製の支承片が設けられている（例えば特許文献１参照）。   As another aspect, a packing material for packing an engine as an object to be packed has been proposed. This packing material includes a metal support device (receiving material) that supports the engine and a metal pallet base that supports the support device. In the support device, a plate-like support frame (support plate) is erected from a pallet base, and a metal support piece for supporting the engine is provided on a flange portion serving as an end of the support frame.

実公平６−２７５９１号公報No. 6-27591

しかしながら、上述した梱包材を用いて、梱包又は開梱時に梱包材から被梱包物を出し入れする作業の際、受け材として図７に示す円柱状の金属支柱２１を用い、その端面２１ａに緩衝材を配置したとしても、被梱包物Ｗと金属支柱２１の側面２１ｂとが金属接触し、被梱包物Ｗに傷がつくことがあった。従って、この出し入れ作業を行う場合、作業者は、前記接触を防ぐように、その作業を慎重にせねばならず、作業に時間がかかることがあった。   However, when packing or unpacking the packing material using the above-described packing material, a columnar metal column 21 shown in FIG. 7 is used as a receiving material, and a cushioning material is provided on the end surface 21a. Even if it arrange | positions, the to-be-packaged goods W and the side surface 21b of the metal support | pillar 21 may contact metal, and the to-be-packaged goods W might be damaged. Therefore, when performing this taking-in / out operation | work, the operator had to be careful of the operation | work so that the said contact might be prevented, and the operation | work could take time.

このような点を鑑みて、受け材の側面と接触するおそれがある被梱包物の部分に、ウレタンゴムなどの緩衝材（被梱包物を保護する部材）を用いて、被梱包物を予備梱包することがある。しかしながら、この場合であっても、動力機器や精密機器等の被梱包物は、上述したように全体形状が複雑であるため、緩衝材（保護部材）による梱包及び開梱の作業は、単純作業とはならず、その作業時間に多大な時間を要することがあった。   In view of these points, pre-packaging the packing object using a cushioning material (a member that protects the packing object) such as urethane rubber on the part of the packing object that may come into contact with the side surface of the receiving material There are things to do. However, even in this case, the packaged items such as power equipment and precision equipment have a complicated overall shape as described above. Therefore, packing and unpacking operations using cushioning materials (protective members) are simple operations. However, the work time may take a lot of time.

本発明は、このような点を鑑みてなされたものであり、その目的とするところは、被梱包物を梱包材から出し入れする際、梱包材に接触することによる被梱包物の外的損傷を防止し、これにより、梱包材から被梱包物を簡単に出し入れすることができる保護部材及びこれを用いた梱包材を提供することにある。   The present invention has been made in view of the above points, and the object of the present invention is to prevent external damage to the packaged object due to contact with the packaging material when the packaged material is taken in and out of the packaging material. It is providing the protective member which can prevent and can take in and out a to-be-packaged object easily from a packing material, and a packing material using the same.

上記課題を解決すべく、本発明に係る保護部材は、被梱包物の荷重を端面で受ける受け材と該受け材を支持する基台とを少なくとも備えた梱包材の前記受け材に取り付けて、前記被梱包物を保護するための保護部材であって、該保護部材は、前記受け材の側面を囲繞する発泡樹脂材と、少なくとも前記端面を覆う非発泡樹脂材と、を少なくとも備えることを特徴とする。   In order to solve the above-mentioned problem, the protective member according to the present invention is attached to the receiving material of the packaging material including at least a receiving material that receives the load of the packaged item at the end surface and a base that supports the receiving material, A protective member for protecting the packaged article, wherein the protective member includes at least a foamed resin material surrounding a side surface of the receiving material and a non-foamed resin material covering at least the end surface. And

本発明によれば、受け材に保護部材を取り付けたときに、受け材の側面の周りには、発泡樹脂材が配置され、受け材の端面には非発泡樹脂材が配置される。これにより、梱包材から被梱包物を出し入れした場合、被梱包物は受け材に直接接触することなく、発泡樹脂材または非発泡樹脂材に接触するので被梱包物の外的損傷を回避することができる。この結果、被梱包物の出し入れの作業性がこれまでのものに比べて向上する。   According to the present invention, when the protective member is attached to the receiving material, the foamed resin material is disposed around the side surface of the receiving material, and the non-foamed resin material is disposed on the end surface of the receiving material. As a result, when the packaged item is taken in or out of the packing material, the packaged item does not directly contact the receiving material, but contacts the foamed resin material or the non-foamed resin material, thereby avoiding external damage to the packaged material. Can do. As a result, the workability of taking in and out the package is improved as compared with the conventional ones.

また、発泡樹脂材を用いることにより保護部材の軽量化が図れるばかりでなく、被梱包物と接触頻度の高い受け材の端面には、非発泡樹脂材が配置されるので、被梱包物が接触したとしても、この部分は削り取られ難い。   In addition, not only can the protective member be reduced in weight by using a foamed resin material, but also the non-foamed resin material is placed on the end surface of the receiving material that is frequently contacted with the packaged object, so that the packaged object is in contact Even so, this part is hard to be scraped off.

ここで、本発明にいう「複数の受け材と基台とを備えた梱包材」とは、既存の梱包体ばかりでなく、この保護部材を取り付けるために新たに製造された被梱包物を支持する支持体をも含む概念である。したがって、複数の受け材と基台とからなる既存の梱包材を利用した場合、これに保護部材を取り付けることができるので、安価に被梱包物を保護することができる。また、複数の受け材と基台とを備えた支持体を新たに製造した場合、後述するように、発泡樹脂材の端部にも被梱包物の荷重を分散させて、これを発泡樹脂部材に担わせるようにすることもできる。これにより、受け材の支持断面を従来の受け材のものよりも小さくし、梱包材のさらなる軽量化を図ることができる。   Here, the "packaging material provided with a plurality of receiving materials and a base" as used in the present invention supports not only the existing package but also a newly manufactured package for attaching this protective member. It is a concept including a supporting body. Therefore, when the existing packing material which consists of a some receiving material and a base is utilized, since a protection member can be attached to this, a to-be-packaged object can be protected cheaply. In addition, when a support having a plurality of receiving materials and a base is newly manufactured, as described later, the load of the article to be packed is distributed to the end portion of the foamed resin material, and the foamed resin member It can also be made to carry. Thereby, the support cross section of a receiving material can be made smaller than the thing of the conventional receiving material, and the further weight reduction of a packaging material can be achieved.

そして、このような梱包材は、被梱包物の荷重を支持する強度が必要であることから、例えば、金属やカーボン等の、保護部材の発泡樹脂及び非発泡樹脂よりも硬質かつ高強度の材料からなる。また受け材は、従来から用いられる支柱（例えば図７参照）、特許文献１に示す支持板など、被梱包物の荷重を安定して受ける（支承）ことができるものであれば、その形状及び構造は特に限定されるものではない。従って、本発明に係る発泡樹脂材は、被梱包物と接触する受け材の側面を囲繞すればよく、例えば、可撓性の発泡樹脂シートを受け材に巻き付けたり、複数の発泡樹脂を受け材の周りを接着したりしてもよい。   And since such a packing material needs the intensity | strength which supports the load of a to-be-packaged object, it is harder and higher-strength material than foamed resin and non-foamed resin of protective members, such as a metal and carbon, for example Consists of. Moreover, if the receiving material can stably receive (support) the load of an object to be packed, such as a conventionally used column (see, for example, FIG. 7), a support plate shown in Patent Document 1, the shape and The structure is not particularly limited. Therefore, the foamed resin material according to the present invention only needs to surround the side surface of the receiving material that comes into contact with the object to be packed. For example, a flexible foamed resin sheet is wound around the receiving material or a plurality of foamed resin receiving materials are used. You may glue around.

しかしながら、前記受け材が支柱である場合には、発泡樹脂材には、該支柱を挿入するための貫通孔が形成されていることがより好ましい。本発明によれば、発泡樹脂材の貫通孔を介して、支柱の端部から発泡樹脂材を容易に挿入することができる。これにより、支柱（受け材）への保護部材の取り付け作業を容易に行うことができる。   However, when the receiving material is a support, it is more preferable that the foamed resin material has a through hole for inserting the support. According to the present invention, the foamed resin material can be easily inserted from the end of the support through the through hole of the foamed resin material. Thereby, the attachment operation | work of the protection member to a support | pillar (receiving material) can be performed easily.

また、発泡樹脂材は、各受け材に配置できるよう個別に構成してもよいが、より好ましくは、各受け材を囲繞する発泡樹脂部分が連結するように一体成形されている。本発明によれば、このように一体成形されるので、各受け材の側面に対して同時に発泡樹脂材を囲繞することができ、さらなる作業性の向上を図ることができる。   In addition, the foamed resin material may be individually configured so as to be arranged on each receiving material, but more preferably, the foamed resin material is integrally formed so that the foamed resin portions surrounding each receiving material are connected. According to the present invention, since it is integrally molded in this way, the foamed resin material can be surrounded simultaneously with respect to the side surfaces of the respective receiving materials, and the workability can be further improved.

また、発泡樹脂材は、前記受け材の端面と同一平面上に端面を有しており、該発泡樹脂材の端面は、前記受け材の端面とともに前記非発泡樹脂材に覆われていることがより好ましい。   The foamed resin material has an end surface on the same plane as the end surface of the receiving material, and the end surface of the foamed resin material is covered with the non-foamed resin material together with the end surface of the receiving material. More preferred.

本発明によれば、非発泡樹脂材が、発泡樹脂材の端面も覆うので、被梱包物の荷重の一部を、非発泡樹脂材を介して発泡樹脂材に分散させることができる。さらに、被梱包物の出し入れ時に、仮に非発泡樹脂材が梱包材から脱落した場合であっても、受け材の端面のエッジ近傍には、発泡樹脂材が配置されているので、受け材のエッジと被梱包物との直接接触を回避することができる。   According to the present invention, since the non-foamed resin material also covers the end face of the foamed resin material, a part of the load of the packaged item can be dispersed in the foamed resin material via the non-foamed resin material. Furthermore, even if the non-foamed resin material falls off from the packing material when the package is taken in and out, the foamed resin material is arranged near the edge of the end surface of the receiving material. And direct contact between the package and the packaged item can be avoided.

また、非発泡樹脂材は、受け材の端面を覆うことができれば、接着剤等により受け材の端面に固着してもよいが、より好ましくは、前記非発泡樹脂材には、受け材の端面を含む端部と嵌合する嵌合凹部が形成されている。本発明によれば、受け材の端部を、非発泡樹脂材の嵌合凹部に挿入して、非発泡樹脂材を受け材に嵌合し固定することができる。   Further, the non-foamed resin material may be fixed to the end surface of the receiving material with an adhesive or the like as long as the end surface of the receiving material can be covered. More preferably, the non-foamed resin material has an end surface of the receiving material. The fitting recessed part which fits with the edge part containing is formed. According to the present invention, the end of the receiving material can be inserted into the fitting recess of the non-foamed resin material, and the non-foamed resin material can be fitted and fixed to the receiving material.

前記非発泡樹脂材と発泡樹脂材とは、前述した位置に配置することができるのであれば、これらは離間して配置されていてもよい。しかしながら、より好ましくは、前記非発泡樹脂材は、前記発泡樹脂材に嵌合する嵌合部が形成されている。これにより、非発泡樹脂材を発泡樹脂材に嵌合させた状態の保護部材を、上述した梱包材に配置することができるので、梱包材の製造時の作業性が向上する。さらに、梱包材から被梱包物を出し入れする際に、非発泡樹脂材の位置ずれ、脱落をも防止することができる。   As long as the non-foamed resin material and the foamed resin material can be arranged at the positions described above, they may be arranged apart from each other. However, more preferably, the non-foamed resin material has a fitting portion that fits into the foamed resin material. Thereby, since the protection member in the state in which the non-foamed resin material is fitted to the foamed resin material can be disposed on the above-described packing material, workability at the time of manufacturing the packing material is improved. Furthermore, it is possible to prevent the non-foamed resin material from being misaligned and dropped off when the article to be packed is taken in and out of the packing material.

なお、発泡樹脂材及び非発泡樹脂材を構成する樹脂は、ポリスチレン系樹脂、ポリオレフィン系樹脂の合成樹脂や、ウレタン、ＮＢＲ等の合成ゴムなどを挙げることができ、発泡樹脂材に用いる樹脂は、被梱包物の（衝撃荷重も含む）荷重の緩衝材として作用し、発泡樹脂材に用いる樹脂は、発泡剤を用いて所望の発泡倍率に発泡させることができるものであれば、これらの樹脂は特に限定されるものではない。   Examples of the resin constituting the foamed resin material and the non-foamed resin material include a polystyrene resin, a synthetic resin of a polyolefin resin, a synthetic rubber such as urethane and NBR, and the resin used for the foamed resin material is If the resin used for the foamed resin material acts as a buffer material for the load (including impact load) of the packaged product and can be foamed to a desired expansion ratio using a foaming agent, these resins are It is not particularly limited.

本発明によれば、被梱包物を梱包材から出し入れする際に被梱包物を保護することができ、これにより、梱包材から被梱包物を容易に出し入れすることができる。   ADVANTAGE OF THE INVENTION According to this invention, when taking in / out a to-be-packaged object from a packing material, a to-be-packaged object can be protected, and, thereby, a to-be-packaged object can be easily taken out / in from a packing material.

FIG. 1 is a view for explaining a protective member and a packing material using the same according to the first embodiment of the present invention, and (a) is a schematic perspective view of the protective member and the packing material. b) is a cross-sectional view taken along the line AA in FIG. FIG. 2 is a schematic perspective view for explaining packing of an object to be packed into the packing material shown in FIG.

図１に示すように、本発明に係る保護部材１０Ａは、被梱包物Wを支持する金属製（例えば鉄製）の梱包材（支持体）２０に取り付けて梱包材１Ａとするものである。支持体２０は、４本の金属支柱（受け材）２１と、金属支柱２１を支持する金属基台２２とを少なくとも備えており、エンジンなどの重量物である被梱包物Ｗを支持するものである。   As shown in FIG. 1, the protective member 10A according to the present invention is a packing material 1A that is attached to a metal (for example, iron) packing material (support) 20 that supports an article W to be packed. The support 20 includes at least four metal struts (receiving materials) 21 and a metal base 22 that supports the metal struts 21, and supports a packaged object W that is a heavy object such as an engine. is there.

金属基台２２は、４つの角材を連結したフレーム部２５と、フレーム部２５の内部において、角材を張り渡したサポート部２６とを備えている。各金属支柱２１は、円柱状の支柱であり、被梱包物Ｗの荷重を受ける位置に各端面２１ａが位置するように、サポート部２６から立設して、これに固定されている。なお、ここでは、支持体２０を金属製としたが、被梱包物Wの耐荷重性を満たすものであればカーボンなどの非金属などであってもよい。   The metal base 22 includes a frame portion 25 in which four square members are connected, and a support portion 26 in which the square members are stretched inside the frame portion 25. Each metal column 21 is a columnar column, and is erected from the support portion 26 so that each end surface 21a is positioned at a position where the load of the article to be packed W is received. Here, the support 20 is made of metal, but may be non-metal such as carbon as long as it satisfies the load resistance of the article W to be packed.

保護部材１０Ａは、支持体２０の金属支柱２１に取り付けて、被梱包物Wを保護するためのものであり、各金属支柱２１の側面２１ｂを個別に囲繞する四角柱状の発泡樹脂材１１Ａを有している。ここでは、発泡樹脂材１１Ａは四角柱状であるが、円柱状であってもよい。この場合、円柱には角部がないので被梱包物と接触しても削れが生じ難い。   10 A of protection members are for attaching to the metal support | pillar 21 of the support body 20, and protecting the to-be-packaged object W, and have the square pillar-shaped foaming resin material 11A which surrounds the side surface 21b of each metal support | pillar 21 separately. is doing. Here, the foamed resin material 11A has a quadrangular prism shape, but may have a cylindrical shape. In this case, since the column does not have a corner portion, it is difficult to be cut even if it comes into contact with the packaged object.

また、発泡樹脂材１１Ａは、ポリオレフィン系樹脂を発泡させたものであり、発泡倍率は、２０倍程度である。この種の樹脂は、リサイクル性に長けて経済的であり、さらには他の樹脂に比べて、発泡時の緩衝性に優れかつ軽量である。   Further, the foamed resin material 11A is obtained by foaming a polyolefin resin, and the expansion ratio is about 20 times. This type of resin is economical due to its high recyclability, and further, has superior cushioning properties during foaming and is lighter than other resins.

各発泡樹脂材１１Ａには、金属支柱２１を挿入するための貫通孔１１ａが形成されている。貫通孔１１ａを設けることにより、これを介して金属支柱２１の端部から発泡樹脂材を容易に挿入することができる（図１（ａ）参照）。   Each foamed resin material 11 </ b> A is formed with a through hole 11 a for inserting the metal support 21. By providing the through hole 11a, the foamed resin material can be easily inserted through the end of the metal support 21 (see FIG. 1A).

また、発泡樹脂材１１Ａの金属基台２２側（基端側）の一端部には、サポート部２６に係止する係止溝１１ｂが形成されている。この係止溝１１ｂにより、発泡樹脂材１１Ａの位置決めをすることができると共に、被梱包物Ｗの載置時に、発泡樹脂材１１Ａが円柱状の金属支柱２１の軸芯周りを回転することを防止できる。   A locking groove 11b that locks to the support portion 26 is formed at one end of the foamed resin material 11A on the metal base 22 side (base end side). With this locking groove 11b, the foamed resin material 11A can be positioned, and the foamed resin material 11A is prevented from rotating around the axis of the columnar metal column 21 when the article W is placed. it can.

一方、発泡樹脂材１１Ａの他端部の端面１１ｃは、金属支柱２１の端面２１ａと同一平面上に形成されている。さらに、発泡樹脂材１１Ａの端面１１ｃと、金属支柱２１の端面２１ａとを共に覆うように、ウレタンからなるプレート状の非発泡樹脂材１２Ａが接着剤等を介して、少なくとも端面１１ｃに固着されている。   On the other hand, the end surface 11 c at the other end of the foamed resin material 11 </ b> A is formed on the same plane as the end surface 21 a of the metal column 21. Further, a plate-like non-foamed resin material 12A made of urethane is fixed to at least the end surface 11c with an adhesive or the like so as to cover both the end surface 11c of the foamed resin material 11A and the end surface 21a of the metal support 21. Yes.

なお、支持体２０に保護部材１０Ａを設置する際には、まず、発泡樹脂材１１Ａを設置後、非発泡樹脂材１２Ａを接着してもよく、予め発泡樹脂材１１Ａに非発泡樹脂材１２Ａを接着後、これらを支持体２０に設置してもよい。   When the protective member 10A is installed on the support 20, first, the non-foamed resin material 12A may be bonded to the foamed resin material 11A in advance after the foamed resin material 11A is installed. You may install these in the support body 20 after adhesion | attachment.

上述した保護部材１０Ａを支持体２０に配置した梱包材１Ａを用いて、エンジンなどの被梱包物Ｗを梱包・開梱する（図２参照）。具体的には、梱包時には、梱包材１Ａの上方からクレーン等を用いて、各非発泡樹脂材１２Ａの表面１２ａに被梱包物Ｗの荷重が支承されるように、被梱包物Ｗを梱包材１Ａに載置する（梱包材１Ａに被梱包物Ｗを入れる）。載置後の被梱包物Ｗを、ゴムバンド、専用の金属固定具などを用いて梱包材２０に固定する（図示せず）。また、開梱時には、梱包時の逆の手順を行う。   Using the packing material 1A in which the protective member 10A described above is arranged on the support 20, the article W to be packed such as an engine is packed and unpacked (see FIG. 2). Specifically, at the time of packing, the packing material W is used as a packing material so that the load of the packing material W is supported on the surface 12a of each non-foamed resin material 12A using a crane or the like from above the packing material 1A. It is placed on 1A (the article to be packed W is put in the packing material 1A). The article to be packed W after placement is fixed to the packing material 20 using a rubber band, a dedicated metal fixture, or the like (not shown). When unpacking, reverse the packing procedure.

そして、上述した作業のうち、梱包材１Ａから被梱包物Ｗを出し入れする作業において、被梱包物Ｗは、金属支柱２１に直接接触することなく、発泡樹脂材１１Ａまたは非発泡樹脂材１２Ａを介して接触するので、被梱包物Ｗの外面に傷が付くことはない。   And in the operation | work which puts in / out the to-be-packaged goods W from the packing material 1A among the work mentioned above, the to-be-packaged goods W does not contact the metal support | pillar 21 directly, but via the foamed resin material 11A or the non-foamed resin material 12A. Therefore, the outer surface of the article to be packed W is not damaged.

また、保護部材１０Ａの一部に、発泡樹脂材１１Ａを用いることにより保護部材１０Ａの軽量化が図れるばかりでなく、被梱包物Ｗと接触頻度の高い保護部材１０Ａの支承面には、非発泡樹脂材１２Ａが配置されるので、被梱包物Ｗが接触したとしても、この部分は削り取られ難い。   Further, by using the foamed resin material 11A as a part of the protective member 10A, the protective member 10A can be reduced in weight, and the support surface of the protective member 10A having a high contact frequency with the article W to be packed is not foamed. Since the resin material 12A is arranged, even if the article to be packaged W comes into contact, this portion is difficult to be scraped off.

さらに、非発泡樹脂材１２Ａが、発泡樹脂材１１Ａの端面も覆うので、非発泡樹脂材１２Ａを介して被梱包物Ｗの荷重の一部を、発泡樹脂材１１Ａに分散させることができる。これにより、被梱包物Ｗの荷重を支持する円柱状の金属支柱２１の径（断面積）をさらに小さくすることもでき、梱包材１Ａの軽量化を図ることもできる。   Furthermore, since the non-foamed resin material 12A also covers the end surface of the foamed resin material 11A, a part of the load of the article W to be packed can be dispersed in the foamed resin material 11A via the non-foamed resin material 12A. Thereby, the diameter (cross-sectional area) of the column-shaped metal support | pillar 21 which supports the load of the to-be-packaged object W can also be made smaller, and weight reduction of the packing material 1A can also be achieved.

また、被梱包物Ｗの出し入れ時に、仮に非発泡樹脂材１２Ａが梱包材１Ａから脱落した場合であっても、金属支柱２１の端面２１ａのエッジ近傍には、発泡樹脂材１１Ａが配置されているので、金属支柱２１のエッジと被梱包物Ｗとの直接接触を回避することができる。   Further, even when the non-foamed resin material 12A is dropped from the packing material 1A when the article W is taken in and out, the foamed resin material 11A is disposed in the vicinity of the edge of the end surface 21a of the metal support column 21. Therefore, direct contact between the edge of the metal support 21 and the article to be packed W can be avoided.
