Description

本発明は、帯状製品を芯材に巻回してなるロール製品を輸送、保管するためのロール製品用プロテクターに関し、更に詳しくは、不使用時には該プロテクターを嵩張ることなくコンパクトに積み重ねることができ、且つ強度が大きいロール製品用プロテクターに関する。   The present invention relates to a roll product protector for transporting and storing a roll product obtained by winding a band product around a core material, and more specifically, when not in use, the protector can be compactly stacked without bulking, and It relates to a protector for roll products having high strength.

従来より、プラスチックフィルム、プラスチックシート、紙等の帯状製品を保護、輸送、保管する場合には、図10に示すように、これらの帯状製品R1を芯材R2に巻回してロール製品Rを形成し、輸送、保管中に帯状製品R1の端面及び周面が汚れたり傷付いたりするのを防止するため、ロール製品Rにロール製品用プロテクター(以下、単にプロテクターと称することがある)Pを組み付けて輸送、保管していた。
この従来のプロテクターPは、方形の側板P1の中心付近に中空円筒状の支軸P2を設けてなるもので、ロール製品Rの両端面を一対の側板P1で挟持するとともに、支軸P2を芯材R2の中空孔に挿入してロール製品Rを支持し、必要に応じ、両側板P1の外側に梱包用バンドBを十字状に掛けて全体を緊締される。
Conventionally, in the case of protecting, transporting, and storing belt-like products such as plastic films, plastic sheets, and paper, as shown in FIG. 10, these belt-like products R1 are wound around a core material R2 to form roll products R. And a roll product protector (hereinafter sometimes referred to simply as a protector) P is assembled to the roll product R to prevent the end surface and the circumferential surface of the strip product R1 from being soiled or damaged during transportation and storage. Transport and storage.
This conventional protector P is provided with a hollow cylindrical support shaft P2 near the center of the rectangular side plate P1. While both end faces of the roll product R are held between a pair of side plates P1, the support shaft P2 is cored The roll product R is supported by being inserted into the hollow hole of the material R2, and if necessary, the packing band B is crisscrossed around the outside of the both side plates P1 and the whole is clamped.

しかしながら、このようなプロテクターは、不使用時にプロテクターPを積み重ねて輸送したり保管する際に、図11に示すように、突出した支軸P2の部分が邪魔になってコンパクトに積み重ねることができないため、嵩張ってしまい、輸送や保管の効率を著しく低下させ、また取り扱い性も悪いという問題がある。   However, such a protector can not be stacked compactly because the portion of the protruding support shaft P2 becomes an obstacle as shown in FIG. 11 when stacking and transporting the protector P when not in use. They are bulky, significantly reduce the efficiency of transport and storage, and have problems such as poor handleability.

このような問題を解決するため、積み重ねの際に下側のプロテクターの支持用突起を、上側のプロテクターの窓部に貫通させることにより、嵩張らずに積み重ねることができるロール製品用プロテクターが提案されている(特許文献1参照)。このようなプロテクターは、従来のものと比較して輸送や保管の効率が劇的に改善されたものではあるが、ロール製品の芯材に挿入される支持用突起が、通常は複数の部分に分かれるので、ロール製品の荷重が複数の支持用突起のうちの1〜2個に集中し、破損しやすくなるという問題がある。   In order to solve these problems, a roll product protector has been proposed that can be stacked without bulk by penetrating the support protrusion of the lower protector through the window of the upper protector during stacking. (See Patent Document 1). Although such protectors have dramatically improved the efficiency of transportation and storage as compared to conventional ones, the supporting projections inserted into the core of the roll product usually have a plurality of parts. Because of the separation, there is a problem that the load of the roll product is concentrated on one or two of the plurality of supporting protrusions, and it becomes easily broken.

特開2011−16553号公報JP, 2011-16553, A

本発明はかかる実情に鑑み、上記従来技術の問題点を解消し、積み重ねても支軸の突出部分が邪魔にならず、不使用時には該プロテクターを嵩張ることなくコンパクトに積み重ねることができ、さらに強度が大きいロール製品用プロテクターを提供することを目的とする。   In view of such circumstances, the present invention solves the above-mentioned problems of the prior art, and even when stacked, the protruding portion of the spindle does not get in the way, and the protector can be compactly stacked without bulking when not in use. Is intended to provide a protector for large roll products.

本発明は上記目的を達成するためになされたもので、本発明の特徴は、側板部の裏面中央の円周上に、複数の支持用突起と、該支持用突起が貫通する大きさの窓部が配設され、積み重ねの際に下側のロール製品用プロテクターの支持用突起を、上側のロール製品用プロテクターの窓部に挿入させるロール製品用プロテクターであって、前記複数の支持用突起が、外側を連結する円筒状の外側連結部、又は、内側を連結する円柱状又は円筒状の内側連結部のいずれか一方により連結されているロール製品用プロテクターである。   The present invention has been made to achieve the above object, and a feature of the present invention is to provide a plurality of supporting protrusions and a window having a size such that the supporting protrusions penetrate through the circumference of the center of the back surface of the side plate portion. A roll product protector, wherein the plurality of support projections are disposed so that the support projections of the lower roll product protector are inserted into the windows of the upper roll product protector during stacking. And a protector for a roll product connected by either a cylindrical outer connecting portion connecting the outer side or a cylindrical or cylindrical inner connecting portion connecting the inner side.

本発明の別の特徴は、周辺部に段積み用脚部が設けられているとともに、外側連結部又は内側連結部の積み重ね高さと段積み用脚部の積み重ね高さとが略等しいロール製品用プロテクターである。 Another feature of the present invention is a protector for roll products provided with stacking legs at the periphery and the stacking height of the outer connection or inner connection and the stacking height of the stacking legs being approximately equal. It is.

本発明のロール製品用プロテクターは、下側のプロテクターの支持用突起を、上側のプロテクターの窓部に貫通させるように構成されたロール製品用プロテクターにおいて、複数設けられた支持用突起が外側連結部又は内側連結部で連結されているので、積み重ねる場合に支持用突起が邪魔にならず、コンパクトに積み重ねることができるだけでなく、一部の支持用突起にかかる荷重が外側連結部又は内側連結部により他の支持用突起に分散させるので強度が向上する。支持用突起が外側連結部と内側連結部の両方で連結されていると一層強度が向上するので好ましい。   The protector for a roll product according to the present invention is a protector for a roll product configured to allow the support projections of the lower protector to pass through the windows of the upper protector, wherein the plurality of support projections provided on the outer connecting portion Or, because they are connected by the inner connection portion, the support protrusions do not get in the way when stacking, and it is possible not only to stack compactly, but also the load applied to some of the support protrusions is by the outer connection portion or the inner connection portion The strength is improved by dispersing to other supporting projections. It is preferable that the support protrusions are connected at both the outer connection portion and the inner connection portion because the strength is further improved.

本発明のロール製品用プロテクター1は、例えば図1乃至図2に示したように、側板部2の裏面中央の円周上に、複数の支持用突起4と、該支持用突起4が貫通する大きさの窓部5が配設され、積み重ねの際に下側のロール製品用プロテクター1の支持用突起4を、上側のロール製品用プロテクター1の窓部5に挿入するように構成されており、前記複数の支持用突起4が、外側を連結する円筒状の外側連結部4aと、内側を連結する円柱状又は円筒状の内側連結部4bのいずれか一方により連結されていることを特徴とする。   In the case of the roll product protector 1 according to the present invention, for example, as shown in FIGS. 1 and 2, a plurality of supporting protrusions 4 and the supporting protrusions 4 penetrate on the circumference of the back surface center of the side plate portion 2. A window 5 of a size is provided, and it is configured to insert the support projection 4 of the lower roll product protector 1 into the window 5 of the upper roll product protector 1 during stacking. The plurality of supporting projections 4 are connected by any one of a cylindrical outer connecting portion 4a connecting the outer side and a cylindrical or cylindrical inner connecting portion 4b connecting the inner side. Do.

本発明における側板部2は、従来のプロテクターにおける側板部と実質的に同じものであり、通常は薄板2aの裏面側(ロール製品に装着したときに当該ロール製品と当接する面)を平坦面とし、表面側(ロール製品に装着したときに外側になる面)に適宜リブ2bを設けたものが使用される。但し、支持用突起4が設けられる部分の裏側には、リブ2bを設けない。
薄板2aはプロテクターのサイズにより一概に規定できないが通常1.5〜3mm程度であり、プロテクターの装飾の目的で、あるいは軽量化の目的で透孔3を設けてもよい。
また、側板部2の平面形状は特に限定されず、通常は、安定性や取り扱い性の観点から、図1、図2に示したように正方形状とされることが多いが、3角形、5角形、6角形、8角形等の多角形であってもよく、これらの角部をアール処理したものでもよい。また、円形や楕円形のものでもよい。
The side plate portion 2 in the present invention is substantially the same as the side plate portion in the conventional protector, and normally the back surface side of the thin plate 2a (the surface that comes in contact with the roll product when mounted on the roll product) is a flat surface. The one provided with ribs 2 b on the surface side (the surface which becomes the outer side when attached to the roll product) is used. However, the rib 2b is not provided on the back side of the portion where the support protrusion 4 is provided.
The thin plate 2a can not be generally specified depending on the size of the protector, but is usually about 1.5 to 3 mm, and the through holes 3 may be provided for the purpose of decoration of the protector or for weight reduction.
Further, the planar shape of the side plate portion 2 is not particularly limited, and usually, from the viewpoint of stability and handleability, it is often square as shown in FIG. 1 and FIG. It may be a polygon such as a square, a hexagon, an octagon or the like, or may be rounded at its corners. Also, it may be circular or oval.

本発明における支持用突起4は、従来のプロテクターにおける支軸と同様、芯材の中空孔に挿入して、ロール製品の幅面が梱包用バンドやダンボールの内面と接しないように懸垂状に支持する目的で設けられているが、従来の支軸とは異なり、複数の支持用突起4を用いて1つのロール製品を支持するようにされている。なお、図示した例では支持用突起4は中実の突起とされているが、リブで補強された中空体とすることも可能であり、その場合には軽量で且つ十分な強度を有する支持用突起4が得られる。
支持用突起4の設置個数は特に限定されないが、通常は4〜8個程度とされる。図3、図4に示すように、本発明による支持用突起4の数は奇数でもよい。これらの支持用突起4が円周上に配置されてロール製品の芯管の中に嵌入できるようにされている。
The supporting projection 4 in the present invention is inserted into the hollow hole of the core material and supported in a suspended manner so that the width surface of the roll product does not contact the inner surface of the packing band or cardboard, like the support shaft in the conventional protector. Although provided for the purpose, unlike conventional spindles, a plurality of supporting protrusions 4 are used to support one roll product. In the illustrated example, the supporting projection 4 is a solid projection, but it may be a hollow body reinforced with a rib, in which case it is lightweight and has sufficient strength for supporting The projections 4 are obtained.
The number of supporting projections 4 is not particularly limited, but is usually about 4 to 8. As shown in FIGS. 3 and 4, the number of the supporting projections 4 according to the present invention may be an odd number. These supporting projections 4 are arranged circumferentially so that they can be fitted into the core tube of the rolled product.

支持用突起4は、図1(b)に示す通り、側板部2の裏面から立設されている。その高さについては、ロール製品の大きさや重量等に応じて適宜決定すればよいが、一般に、ロール製品を確実に支持するために、過度に嵩張らない範囲で高いほうが好ましい。プロテクター1に段積み用脚部6を設けない場合、前記側板部2の厚さの1〜3倍程度が好ましく、積み重ね効率からは、1〜2倍程度がより好ましい。
即ち、通常の場合、側板部2は薄板2aの表面側に所定高さのリブ2bが設けられ、このリブ2bの高さと薄板2aの厚さの和が側板部2の厚さとなるが、支持用突起4の高さが側板部2の厚さの1倍未満の場合は、支持用突起4が一枚上に載置されたプロテクター1のリブ2bの間に入り込み、窓部5を貫通しないため、窓部5を設けた意味が乏しくなる。また、2倍を超えた場合は支持用突起4が2枚上に載置されたプロテクター1のリブ2bの間を通り抜け、その薄板2aに当接するため、積み重ねられたプロテクター1の間に隙間ができ、積み重ね効率が低下する傾向がある。
The supporting projections 4 are erected from the back surface of the side plate portion 2 as shown in FIG. The height may be appropriately determined in accordance with the size, weight, and the like of the roll product, but in general, in order to reliably support the roll product, it is preferable to be as high as possible without excessively bulky. When the stacking legs 6 are not provided in the protector 1, the thickness is preferably about 1 to 3 times the thickness of the side plate 2, and more preferably about 1 to 2 times in terms of stacking efficiency.
That is, in the normal case, the side plate portion 2 is provided with the rib 2b of a predetermined height on the surface side of the thin plate 2a, and the sum of the height of the rib 2b and the thickness of the thin plate 2a becomes the thickness of the side plate portion 2 When the height of the projection 4 is less than one time of the thickness of the side plate 2, the supporting projection 4 enters between the ribs 2b of the protector 1 placed on one sheet and does not penetrate the window 5. Therefore, the meaning of providing the window portion 5 is poor. In addition, when it exceeds 2 times, the support projection 4 passes through between the ribs 2b of the protector 1 placed on the two sheets and abuts against the thin plate 2a, so there is a gap between the stacked protectors 1 There is a tendency to reduce the stacking efficiency.

段積み用脚部6を設ける場合、支持用突起4の高さは、段積み用脚部6の積み重ね高さの1〜3倍程度が好ましく、積み重ね効率からは、1〜2倍程度がより好ましい。
支持用突起4の高さが段積み用脚部6の積み重ね高さの1倍未満の場合は、支持用突起4が一枚上に載置されたプロテクター1の裏面に到達せず、窓部5を貫通しないため、窓部5を設けた意味が乏しくなる。また、2倍を超えた場合は支持用突起4が2枚上に載置されたプロテクター1の表面側に当接するため、積み重ねられたプロテクター1の間に隙間ができ、積み重ね効率が低下する傾向がある。
When the stacking legs 6 are provided, the height of the support projections 4 is preferably about 1 to 3 times the stacking height of the stacking legs 6, and from the stacking efficiency, about 1 to 2 times more preferable.
If the height of the supporting projections 4 is less than one times the stacking height of the stacking legs 6, the supporting projections 4 do not reach the back surface of the protector 1 placed on one sheet, and the window section Since it does not penetrate 5, the meaning of providing the window part 5 becomes scarce. In addition, when it exceeds 2 times, the supporting projections 4 abut on the surface side of the protector 1 placed on two sheets, so a gap is formed between the stacked protectors 1 and the stacking efficiency tends to be reduced. There is.

本発明における窓部5は上記側板部2に穿設される孔であり、プロテクター1を積み重ねる際に、上記の支持用突起4が貫通される部分で、支持用突起4と同じ円周上に設けられる。その大きさ、形状は上記支持用突起4が貫通可能な形状、大きさである限り特に限定されないが、大きすぎると側板部2の強度が下がり、また積み重ねた際に不安定となるので、可能な限り小さいほうがよく、具体的には、支持用突起4の断面形状と略同じ大きさ、形状とするほうが好ましい。また、窓部5の設置個数も特に制限されないが、通常は支持用突起4の数と同数である。なお、図1及び図2に示した例では支持用突起4が6個であるのに対し窓部5も6個設けられており、また図3及び図4に示した例では支持用突起4が5個であるのに対し窓部5も5個設けられている。   The window portion 5 in the present invention is a hole drilled in the side plate portion 2, and when stacking the protectors 1, the supporting protrusion 4 is penetrated at the same circumference as the supporting protrusion 4. Provided. The size and shape thereof are not particularly limited as long as the shape and size of the supporting projections 4 can be penetrated. However, if the size is too large, the strength of the side plate portion 2 decreases and it becomes unstable when stacked. It is preferable that the size be as small as possible, and specifically, it is preferable that the size and shape of the cross-sectional shape of the support protrusion 4 be approximately the same. Further, the number of the installed window parts 5 is not particularly limited, but is usually the same as the number of the support protrusions 4. In the example shown in FIGS. 1 and 2, the number of supporting projections 4 is six while the number of windows 5 is six, and in the example shown in FIGS. 3 and 4, the supporting projections 4 While five are provided, five windows 5 are also provided.

上記した通り、積み重ねの際には窓部5には支持用突起4が貫通されるので、窓部5の配置パターンは支持用突起4の配置パターンと略同一になる。しかしながら、支持用突起4と窓部5の両方が側板部2の中央の同じ円周上に配設されるので、窓部5と支持用突起4の配置によっては、窓部5の位置と支持用突起4の位置が全く同じになってしまい、実質的に窓部5を設けることが出来なくなる場合がある。このような場合には窓部5の配置が支持用突起4の配置と重ならないように、窓部5の配置パターンを支持用突起4の配置パターンに対して適当な角度だけ回転させたような配置にすればよい。   As described above, since the support projections 4 are penetrated through the windows 5 when stacking, the arrangement pattern of the windows 5 becomes substantially the same as the arrangement pattern of the support projections 4. However, since both the support protrusion 4 and the window 5 are disposed on the same circumference of the center of the side plate 2, depending on the arrangement of the window 5 and the support protrusion 4, the position and support of the window 5 The position of the projection 4 may be exactly the same, and the window 5 may not be provided substantially. In such a case, the arrangement pattern of the windows 5 is rotated by an appropriate angle with respect to the arrangement pattern of the support projections 4 so that the arrangement of the windows 5 does not overlap the arrangement of the support projections 4. It should be arranged.

但し、支持用突起4の形状及び配置パターンによっては、支持用突起4と窓部5の配置パターンが重ならないような回転角度が無い場合もあるので、例えば、円形を約12分の1に分割した形状、円筒状、板状を等間隔に円周上に配置する等のように、配置角度を異ならしめることにより支持用突起4と窓部5の配置パターンが重ならなくなるような形状を選択すればよい。最も単純には、支持用突起4と窓部5を等間隔且つ交互に配設すれば、支持用突起4と窓部5の配置パターンが重ならない形状になる。なお、図1及び図2に示した例では、ドーナツ型を約12分割した形状の6個の支持用突起4と、前記支持用突起4の断面形状よりも若干大きい6個の窓部5を交互に配置した形状が採用されている。   However, depending on the shape and arrangement pattern of the support projections 4, there may not be a rotation angle such that the arrangement pattern of the support projections 4 and the window 5 does not overlap. Select a shape such that the arrangement pattern of the support projection 4 and the window 5 does not overlap by making the arrangement angle different, such as arranging the shapes, cylinders, and plates on the circumference at equal intervals. do it. In the simplest case, if the supporting projections 4 and the windows 5 are alternately arranged at equal intervals, the arrangement pattern of the supporting projections 4 and the windows 5 does not overlap. In the example shown in FIGS. 1 and 2, six supporting protrusions 4 having a donut shape divided into about twelve portions, and six window portions 5 slightly larger than the sectional shape of the supporting protrusions 4 are provided. The alternately arranged shapes are adopted.

本発明のプロテクター1を積み重ねるには、上側のプロテクター1Aを下側のプロテクター1Bに対して所定角度回転させる。図3、図4に示したプロテクター1(支持用突起4、窓部5がいずれも5個)を積み重ねる場合は、図5に示すように、上側のプロテクター1Aの適切な回転角度は180°である。
このようにすれば、図6(a)に示したように、下側のプロテクター1Bの支持用突起4の上に上側のプロテクター1Aの窓部5が配置され、下側プロテクター1Bの支持用突起4が上側プロテクター1Bの窓部5を貫通できるようになるので、図6(b)のように順次コンパクトに積み重ねることが可能になる。
また、図1、図2に示したプロテクター1(支持用突起4、窓部5がいずれも6個)の場合における上側のプロテクター1Aの適当な回転角度は90°である。
図7(a)、(b)は、図1、図2のプロテクター1を積み重ねた状態を示す。この場合も、図7(a)に示したように、下側のプロテクター1Bの支持用突起4の上に上側のプロテクター1Aの窓部5が配置され、下側プロテクター1Bの支持用突起4が上側プロテクター1Bの窓部5を貫通できるようになるので、図7(b)のように順次コンパクトに積み重ねることが可能になる。
In order to stack the protectors 1 of the present invention, the upper protector 1A is rotated by a predetermined angle with respect to the lower protector 1B. When stacking the protectors 1 (five supporting protrusions 4 and five windows 5 shown in FIGS. 3 and 4), as shown in FIG. 5, the appropriate rotation angle of the upper protector 1A is 180 °. is there.
In this way, as shown in FIG. 6A, the window 5 of the upper protector 1A is disposed on the support projection 4 of the lower protector 1B, and the support projection of the lower protector 1B. Since 4 can penetrate through the window 5 of the upper protector 1B, it becomes possible to stack them compactly one by one as shown in FIG. 6 (b).
Further, the appropriate rotation angle of the upper protector 1A in the case of the protector 1 shown in FIGS. 1 and 2 (the number of the supporting projections 4 and the number of the windows 5 is six) is 90 °.
FIGS. 7A and 7B show a state in which the protectors 1 of FIGS. 1 and 2 are stacked. Also in this case, as shown in FIG. 7A, the window 5 of the upper protector 1A is disposed on the support protrusion 4 of the lower protector 1B, and the support protrusion 4 of the lower protector 1B is Since the window 5 of the upper protector 1B can be penetrated, it becomes possible to stack them in a compact manner as shown in FIG. 7 (b).

本発明は前記複数の支持用突起4が、外側連結部4aと、内側連結部4bの、少なくともいずれか一方により連結されていることを特徴とする。
図1に示すように、本発明において外側連結部4aとは環状に列設された支持用突起4の外側に着設された円筒状の部分であり、内側連結部4bとは環状に列設された支持用突起4の内側に着設された円柱状又は円筒状の部分である。
本発明において外側連結部4a及び内側連結部4bは、プロテクター1をロール製品に装着した際、ロール製品の荷重で支持用突起4が破損するのを防止する働きをする。即ち、一の支持用突起4にかかるロール製品の荷重を外側連結部4a及び内側連結部4bを通して他の支持用突起4に分散し、全ての支持用突起4でロール製品を支持するように構成されているので、荷重が特定の支持用突起4に集中するのを防ぎ、破損を防止することができる。
The present invention is characterized in that the plurality of supporting protrusions 4 are connected by at least one of the outer connecting portion 4a and the inner connecting portion 4b.
As shown in FIG. 1, in the present invention, the outer connecting portion 4a is a cylindrical portion attached to the outside of the supporting projections 4 annularly arranged, and the inner connecting portion 4b is arranged in an annular array It is a cylindrical or cylindrical portion attached to the inside of the supporting protrusion 4.
In the present invention, the outer connecting portion 4a and the inner connecting portion 4b function to prevent the supporting projections 4 from being damaged by the load of the roll product when the protector 1 is attached to the roll product. That is, the load of the roll product applied to one supporting projection 4 is dispersed to the other supporting projections 4 through the outer connecting portion 4a and the inner connecting portion 4b, and all the supporting projections 4 support the rolled product. As a result, the load can be prevented from concentrating on a specific support projection 4 and breakage can be prevented.

本発明において外側連結部4aと内側連結部4bの高さは特に限定されないが、段積み用脚部6が設けられない場合は、高さを支持用突起4の0.3〜0.6倍程度とすれば、支持用突起4の強度が高く、且つ収納効率が高いプロテクター1が得られる。外側連結部4a及び内側連結部4bの高さが支持用突起4の0.3倍未満であれば、一の支持用突起4にかかる荷重を他の支持用突起4に分散しにくくなり、強度が低下する傾向にある。0.6倍よりも高ければ、積み重ね効率が低下する傾向にある。
段積み用脚部6を設ける場合には、外側連結部4a及び内側連結部4bの積み重ね高さを段積み用脚部6の積み重ね高さと略等しくなるようにすれば、支持用突起4の強度を十分高めることができるとともに、積み重ね効率も高くなる。なお、外側連結部4a及び内側連結部4bの積み重ね高さとは、脚部を無視して外側連結部4a及び内側連結部のみを積み重ねた場合の外側連結部4a及び内側連結部4bの一つ当たりの高さをいい、同様に段積み用脚部6の積み重ね高さとは外側連結部4a及び内側連結部を無視して段積み用脚部6のみを積重ねた場合の段積み用脚部6の一つ当たりの高さをいう。
In the present invention, the heights of the outer connection portion 4a and the inner connection portion 4b are not particularly limited, but when the stacking legs 6 are not provided, the height is 0.3 to 0.6 times the height of the support projection 4 If it makes a grade, the intensity | strength of the protrusion 4 for support is high, and the protector 1 with high storage efficiency will be obtained. If the height of the outer connection portion 4a and the inner connection portion 4b is less than 0.3 times the height of the support protrusion 4, it becomes difficult to disperse the load applied to one support protrusion 4 to the other support protrusions 4, and the strength Tend to decrease. If it is higher than 0.6 times, the stacking efficiency tends to decrease.
If the stacking legs 6 are provided, the strength of the supporting projections 4 can be obtained by making the stacking height of the outer connecting portion 4 a and the inner connecting portion 4 b substantially equal to the stacking height of the stacking legs 6. And the stacking efficiency is also high. The stacking height of the outer connecting portion 4a and the inner connecting portion 4b means one outer connecting portion 4a and one inner connecting portion 4b in the case where only the outer connecting portion 4a and the inner connecting portion are stacked without regard to the legs. Similarly, the stacking height of the stacking legs 6 refers to the height of the stacking legs 6 when only the stacking legs 6 are stacked without regard to the outer connecting portion 4a and the inner connecting portion. It says the height per one.

図1〜4に示した例において、支持用突起4は外側連結部4aと内側連結部4bの両方に連結されているが、本発明においては必ずしも両方に連結する必要はなく、例えば図8に示すように内側連結部4bだけに連結してもよいし、図9に示すように、外側連結部4aだけに連結してもよい。   In the example shown in FIGS. 1 to 4, the supporting projections 4 are connected to both the outer connecting portion 4 a and the inner connecting portion 4 b, but in the present invention, it is not necessary to connect to both. As shown, it may be connected only to the inner connection part 4b, and as shown in FIG. 9, it may be connected only to the outer connection part 4a.

本発明のロール製品用プロテクターの材質は特に限定されないが、加工が容易で、且つ軽量である点で樹脂が好ましく、例えば、例えば、ABS樹脂(アクリロニトリル−ブタジエン- スチレン共重合樹脂)、AAS樹脂(アクリロニトリル/アクリルゴム/スチレン樹脂)、AES樹脂(アクリロニトリル/エチレンプロピレンゴム/スチレン樹脂)、AS樹脂(アクリロニトリル/スチレン樹脂)、PS樹脂(ポリスチレン樹脂)、PMMA樹脂(ポリメチルメタクリレート樹脂)、PVC樹脂(ポリ塩化ビニリデン樹脂)、MS樹脂(メチルメタクリレート/スチレン樹脂)、PP樹脂(ポリプロピレン樹脂)、PE樹脂(ポリエチレン樹脂)、PBT樹脂(ポリブチレンテレフタレート樹脂)およびPC樹脂(ポリカーボネート樹脂)等が使用可能である。更に、ポリ乳酸樹脂、ポリブチレンサクシネート、ポリアミド11、ポリヒドロキシ酪酸等の生分解性プラスチック、バイオマスプラスチック等も使用可能である。生分解性プラスチックを用いた場合は、化石資源の使用を減少させ、特に、バイオマスプラスチックは植物由来の素材からなるので焼却処分しても植物が固定したCO2 が排出されるだけであるので、CO2 排出量が増えないカーボンニュートラルが達成され、環境に優しく地球温暖化防止に寄与する利点がある。 The material of the protector for a roll product of the present invention is not particularly limited, but is preferably a resin from the viewpoint of easy processing and light weight, for example, ABS resin (acrylonitrile-butadiene-styrene copolymer resin), AAS resin (AAS resin) Acrylonitrile / acrylic rubber / styrene resin), AES resin (acrylonitrile / ethylene propylene rubber / styrene resin), AS resin (acrylonitrile / styrene resin), PS resin (polystyrene resin), PMMA resin (polymethyl methacrylate resin), PVC resin (polymethyl methacrylate resin) Polyvinylidene chloride resin), MS resin (methyl methacrylate / styrene resin), PP resin (polypropylene resin), PE resin (polyethylene resin), PBT resin (polybutylene terephthalate resin) and PC resin (polycarbonate resin) Etc. can be used. Furthermore, biodegradable plastics such as polylactic acid resin, polybutylene succinate, polyamide 11, polyhydroxybutyric acid, biomass plastics and the like can also be used. When biodegradable plastics are used, the use of fossil resources is reduced, and in particular, since biomass plastics are made of plant-derived materials, incineration disposal only results in the emission of CO 2 fixed by plants. Carbon neutrality, which does not increase CO 2 emissions, is achieved, which has the advantage of being environmentally friendly and contributing to the prevention of global warming.

上記したとおり、本発明のロール製品用プロテクターは、複数の支持用突起が外側連結部又は内側連結部により連結されているので、単に輸送や保管効率が良く、取り扱い性が良好なだけでなく、支持用突起の強度が大きく破損しにくいロール製品用プロテクターが提供される。   As described above, in the protector for a roll product according to the present invention, since the plurality of supporting projections are connected by the outer connection portion or the inner connection portion, not only good transport and storage efficiency but also good handleability are obtained. There is provided a protector for roll products in which the strength of the supporting projections is large and the breakage is difficult.
