Description

本発明は、レンジフードのファンの吸い込み口側に交換可能に取付けられ、油などの汚れを付着させてファンの汚れを防止するファン用フィルターに関する。   The present invention relates to a fan filter that is replaceably attached to a suction port side of a fan of a range hood and prevents dirt on the fan by attaching dirt such as oil.

従来より、レンジフードには金属製フィルターがファンの前面に設置されており、吸い込まれた油煙はこの金属製フィルターに設けられたスリット状の細かい隙間に触れることで油の粒子等が付着される。この金属製フィルターの汚れを防止するために、不織布製フィルターやアルミニウム枠付きカバー等が金属製フィルターに取付けられることがあり、また、近年では、金属製フィルターを設けることなく、ファンの前面に整流板が取付けられ、この整流板により吸気速度が加速されることで油煙がキャッチされ、油がオイルトレーに溜まるようにした機構も知られている。   Conventionally, a metal filter has been installed in the front of the fan in the range hood, and the oil particles that are sucked in by touching the fine slit-shaped gap provided in the metal filter. . In order to prevent contamination of this metal filter, a non-woven filter or a cover with an aluminum frame may be attached to the metal filter. In recent years, rectification is performed on the front face of the fan without providing a metal filter. There is also known a mechanism in which a plate is attached and oil flow is caught by accelerating the intake speed by this baffle plate so that the oil is accumulated in an oil tray.

このようなレンジフードでは、ダクトの長さや住宅の形態などにより各種のファンが用いられてきたが、最近では住宅の気密性の向上によってシロッコファンに集約されつつある。特に、シロッコファンに油汚れが付着すると、表面を拭き取るだけでは汚れを十分に落とすことが難しいため、ファンの回転翼部分をレンジフードから取り外して清掃する必要が生じ、その作業が非常に面倒になっている。
そこで、ファンや金属製フィルターへの油汚れの付着を防止し、しかも金属製フィルターが装着されていない場合にも、ファンの油汚れを防止できるようにしたファン用フィルターが提案されている。
In such a range hood, various fans have been used depending on the length of the duct, the form of the house, and the like, but recently, they are being integrated into sirocco fans due to the improvement of the airtightness of the house. In particular, if oil stains adhere to the sirocco fan, it is difficult to remove the stains sufficiently by simply wiping the surface.Therefore, it is necessary to remove the fan blades from the range hood and clean them, which is very troublesome. It has become.
In view of this, a fan filter has been proposed that prevents oil stains from adhering to the fan and the metal filter and prevents the fan from being contaminated even when the metal filter is not attached.

この種のファン用フィルターとして、例えば、特許文献1のシロッコファン用フィルター構造体が開示されている。このファン用フィルター構造体では、フィルターと、フィルターを広げた状態に保持する保持手段と、保持手段が取付けられたフィルターを固定する固定手段が設けられ、フィルターは、金属製フィルターを外した状態で保持手段の枠体により吸気口の前面に広げられながら固定手段の磁石により取付けられる。
特許文献2のレンジフード用フィルターは、上方部の両端角隅部に磁石を備えた金属把手、下方部に着脱用磁石を有するフィルターであり、ファンの前面側の開口に設けられた金属製フィルターの前面の全体を覆うように取付けられる。
特許文献3においては、磁石片が装着されたアルミシート材が開示されており、この中でアルミシート材にフィルターが張設され、両側縁部の耳部に磁石片が設けられたレンジフード取付け用のフード用フィルターが記載されている。
As this type of fan filter, for example, a filter structure for a sirocco fan disclosed in Patent Document 1 is disclosed. In this fan filter structure, a filter, a holding means for holding the filter in an unfolded state, and a fixing means for fixing the filter to which the holding means is attached are provided. It is attached by the magnet of the fixing means while being spread on the front surface of the intake port by the frame of the holding means.
The filter for the range hood of Patent Document 2 is a filter having a metal handle with magnets at both corners at the upper part and a detachable magnet at the lower part, and a metal filter provided at the opening on the front side of the fan It is attached so as to cover the entire front surface.
Patent Document 3 discloses an aluminum sheet material on which magnet pieces are mounted, in which a filter is stretched on the aluminum sheet material, and a range hood is mounted with magnet pieces provided on the ears of both side edges. A hood filter is described.

特許第4936500号公報Japanese Patent No. 4936500 特開平9−29031号公報Japanese Patent Laid-Open No. 9-29031 実公平7−37081号公報No. 7-37081

しかしながら、特許文献1のフィルター構造体は、金属製フィルターが外された状態のレンジフードに対して、シート状のフィルターが保持手段で保持されつつ、固定手段で固定されることでこれらパーツが組み合わされて一体化されているため取扱いづらくなり、シート状フィルターが着脱時に撓んだり折れ曲がったりするおそれがあった。
特許文献2のレンジフード用フィルターは、金属製フィルターの前面全体を覆う形状であるため全体が大きくなり、コストアップにもつながるという問題が生じていた。
However, in the filter structure of Patent Document 1, these parts are combined by fixing the sheet-like filter with the holding means while fixing the sheet-like filter to the range hood with the metal filter removed. Since they are integrated, it is difficult to handle, and there is a possibility that the sheet-like filter may bend or bend during attachment / detachment.
The filter for the range hood of Patent Document 2 has a shape that covers the entire front surface of the metal filter, so that the entire size is increased, leading to an increase in cost.

特許文献3においては、補強枠部が設けられたアルミニウム製の周枠にフード用フィルターが取付けられ、この周枠に設けられた磁石片を介してレンジフードに着脱していることで、ファン部分のみを覆いながら着脱することは可能である。しかし、このフード用フィルターを包装した場合、その強度を十分に確保することが難しくなる。すなわち、この四角形状のフード用フィルターをその形状に沿った四角形状の袋に収納した場合、角部が下向きで落下したときにその接触部分が点接触に近い状態になるため、衝撃が大きく伝わって変形したり潰れたりする可能性がある。
一方、円形状のファン用フィルターである場合、この円形フィルターの収納用の袋も四角形状に設けられるが、この場合、落下したときに円形フィルターが点接触で接地するためにその衝撃力が大きくなって潰れやすくなる。そのため、この種のフィルター包装用袋には、衝撃吸収用の台紙が内装されることもある。
In Patent Document 3, a hood filter is attached to an aluminum peripheral frame provided with a reinforcing frame, and the fan portion is attached to and detached from the range hood via a magnet piece provided on the peripheral frame. It is possible to attach and detach while covering only. However, when this hood filter is packaged, it is difficult to ensure sufficient strength. In other words, when this rectangular hood filter is stored in a rectangular bag along its shape, the contact portion becomes close to point contact when the corner part falls downward, so that the impact is transmitted greatly. May be deformed or crushed.
On the other hand, in the case of a circular fan filter, the storage bag for the circular filter is also provided in a square shape. In this case, the impact force is large because the circular filter is grounded by point contact when dropped. It becomes easy to collapse. For this reason, this type of filter packaging bag may be provided with a shock absorbing mount.

本発明は、このような事情に鑑みてなされたもので、レンジフードへの着脱時に取扱いが容易であり、全体をコンパクト化しつつ油汚れを付着させてファンの汚れを防止し、落下に対する強度を向上して変形や潰れを防止できるようにしたファン用フィルターを提供することを目的とする。   The present invention has been made in view of such circumstances, and is easy to handle when attaching to and detaching from the range hood. An object of the present invention is to provide a fan filter that can be improved to prevent deformation and crushing.

本発明のファン用フィルターは、強度部材からなる枠部の外形が外部を面取りした四角形又は五角形以上の多角形状に形成され、この枠部に設けられた開口部を覆うように不織布フィルターが設けられ、前記枠部の一部に着脱のための取付部が設けられていることを特徴とする。   In the fan filter of the present invention, the outer shape of the frame portion made of a strength member is formed into a polygonal shape with a chamfered exterior or a pentagon, and a nonwoven fabric filter is provided so as to cover the opening provided in the frame portion. A mounting portion for attaching and detaching is provided on a part of the frame portion.

このように、多角形状に形成された枠部に不織布フィルターが開口部を覆うように設けられていることで、不織布フィルターが補強されて撓んだり折れ曲がったりすることがなく、枠部と一体にレンジフードに着脱することができる。多角形状の枠部をファンの吸い込み口と同形状に設けることで、全体がコンパクト化されながら油汚れが付着しやすい部分を覆うことが可能になり、材料も最小限になりコスト的にも有利となる。枠部に一体化されたフィルターを取付部を介してレンジフィルターに着脱することができるため、接着用のテープや取付け用の工具を必要とすることなく、各種のファンに使用可能となる。さらには、金属製フィルターに取り付けられるタイプのフィルターやアルミ付きカバーとの併用も可能になる。   In this way, the nonwoven fabric filter is provided on the frame portion formed in a polygonal shape so as to cover the opening, so that the nonwoven fabric filter is reinforced and does not bend or bend, and is integrated with the frame portion. Can be attached to and detached from the range hood. By providing a polygonal frame with the same shape as the fan suction port, it is possible to cover parts that are susceptible to oil contamination while being made compact as a whole. It becomes. Since the filter integrated with the frame portion can be attached to and detached from the range filter via the attachment portion, the filter can be used for various fans without requiring an adhesive tape or an attachment tool. Furthermore, it is possible to use a filter attached to a metal filter or a cover with aluminum.

本発明のファン用フィルターにおいて、店頭陳列用の包装具内に収納されており、該包装具が、前記枠部を収納し得る大きさの正面視四角形状の偏平な収納部と、該収納部の上端に連設され、引掛け用の孔部を有するヘッダ部とからなり、前記収納部の底辺に前記枠部の任意の一辺が対向しつつ前記収納部の両側辺により前記枠部の側部が位置規制され、前記枠部が前記収納部内で回転不能の状態で収納されているとよい。   The fan filter of the present invention is housed in a store display packaging tool, and the packaging tool has a rectangular storage section having a square shape in front view and a size capable of storing the frame section, and the storage section. And a header portion having a hooking hole, and an arbitrary side of the frame portion is opposed to the bottom side of the storage portion, and the side of the frame portion is disposed on both sides of the storage portion. It is preferable that the position of the part is restricted and the frame part is stored in a non-rotatable state in the storage part.

この包装具への枠部の収納時には、収納部の底辺に多角形状の枠部の任意の一辺が支持されて枠部が安定して収納される。そして、ヘッダ部の孔部にフックを引っ掛けて店頭陳列されるが、その陳列状態から取り外した際等に、包装具が収納部の底辺から落下した場合には、この底辺から枠部の一辺側に床面や地面からの衝撃が線接触に近い状態で伝達される。このため、衝撃力が分散され、枠部全体の変形や潰れが防がれる。一方、包装具が傾いた状態で収納部の底辺と側辺との間の角部を下にして落下した場合には、この角部付近に枠部の辺が位置しておらず、その衝撃力が収納部によって吸収されるために枠部全体の変形や潰れが防止される。   When the frame part is stored in the packaging tool, any one side of the polygonal frame part is supported on the bottom side of the storage part, and the frame part is stably stored. And when hooks are hooked in the holes of the header part and displayed in the storefront, when the packaging tool falls from the bottom side of the storage part when removed from the display state, one side of the frame part from this bottom side The impact from the floor or the ground is transmitted in a state close to line contact. For this reason, the impact force is dispersed, and deformation or crushing of the entire frame portion is prevented. On the other hand, when the packaging tool is tilted and dropped with the corner between the bottom and side of the storage section facing down, the side of the frame is not located near this corner, and the impact Since the force is absorbed by the storage portion, the entire frame portion is prevented from being deformed or crushed.

本発明のファン用フィルターにおいて、前記枠部の開口部に帯状に補強部が架け渡し状態で設けられていることが望ましい。
帯状に補強部が設けられていることで枠部が補強され、落下により外力が加わった場合にも枠部を潰す方向の変形が防がれる。使用時においても歪みの発生が防止され、ファンとの隙間の発生が抑えられた状態で装着することができ、ファンへの油の付着防止機能が高まる。
In the fan filter of the present invention, it is desirable that a reinforcing portion is provided in a belt-like manner at the opening of the frame portion.
The frame portion is reinforced by providing the reinforcing portion in a band shape, and deformation in the direction of crushing the frame portion is prevented even when an external force is applied by dropping. Even when in use, distortion can be prevented and mounting can be performed in a state where a gap with the fan is suppressed, and the function of preventing the adhesion of oil to the fan is enhanced.

本発明のファン用フィルターにおいて、前記枠部の外形は、六角形から十二角形までの多角形状であるとよい。
これにより、円形状の吸い込み口を有するシロッコファンに沿った枠部外形に設けられ、全体の大型化や使用される材料の量が抑えられる。枠部の任意の一辺が包装具の底辺側に確実に対向しながら枠部が収納されるため、落下したときに底辺側の任意の一辺が線接触で接地しやすくなり枠部の変形や潰れが確実に防止される。
In the fan filter of the present invention, the outer shape of the frame portion may be a polygonal shape from a hexagon to a dodecagon.
Thereby, it is provided in the frame part external shape along the sirocco fan which has a circular suction inlet, and the whole enlargement and the quantity of the material used are suppressed. Since the frame part is stored while the one side of the frame part is securely facing the bottom side of the packaging tool, any one side on the bottom side can be easily grounded by line contact when dropped, and the frame part is deformed or crushed Is reliably prevented.

また、本発明のファン用フィルターにおいて、前記枠部外周の複数箇所に前記取付部が設けられていることが望ましい。
これによると、必要最小限の2か所の取付部の着脱によりファンの筐体への取り付け、取り外しが簡単になり、取り付け後には吸い込み口側の所定位置に強固に装着される。取付部を成す材料を削減でき、製作も容易となる。
Moreover, in the fan filter of the present invention, it is desirable that the attachment portions are provided at a plurality of locations on the outer periphery of the frame portion.
According to this, the attachment and detachment of the fan from the housing becomes easy by attaching and detaching the minimum two attachment portions, and after the attachment, the fan is firmly attached at a predetermined position on the suction port side. The material forming the mounting portion can be reduced, and the manufacture is facilitated.

本発明のファン用フィルターによれば、全体を一体的に取り扱えるためレンジフードへの着脱が容易になり、レンジフードを分解することなく磁石による取付部を介して取付けでき、全体をコンパクト化しつつファンの開口側全体を覆うことで油汚れを付着させてファンの汚れを防止し、多角形状に設けていることで落下に対する強度を向上して変形や潰れを防止できる。   According to the fan filter of the present invention, since the whole can be handled integrally, it can be easily attached to and detached from the range hood, and can be attached via a magnet mounting portion without disassembling the range hood. By covering the entire opening side, oil dirt is adhered to prevent the fan from being dirty, and by providing the polygonal shape, the strength against dropping can be improved and deformation and crushing can be prevented.

以下、本発明のファン用フィルターの実施形態を図面を参照しながら説明する。
図1、図2において、ファン用フィルター1は、例えば、図示しないキッチンの換気扇であるシロッコファンの筐体に設けられた吸い込み口側を覆うように取付けられ、ファンの換気時に湯煙等が吸い込まれて油などの汚れが付着される。このファン用フィルター1は、枠部10と、不織布フィルター20とを有し、その販売の際には、全体が包装具30に収納される。
Hereinafter, embodiments of a fan filter of the present invention will be described with reference to the drawings.
1 and 2, the fan filter 1 is attached so as to cover, for example, a suction port provided in a housing of a sirocco fan, which is a ventilation fan of a kitchen (not shown), and steam or the like is sucked when the fan is ventilated. Oil or other dirt is attached. The fan filter 1 has a frame portion 10 and a nonwoven fabric filter 20, and the whole is stored in a packaging tool 30 when sold.

図1に示すように、枠部10は、アルミニウム箔により形成されており、円筒状の筒状部11の一端に、筒状部11の半径方向外方に延びる外向きフランジ部12が一体に形成されるとともに、筒状部11の他端に、筒状部11の半径方向内方に延びる内向きフランジ部13が一体に形成されている。内向きフランジ部13の内側は開口部14とされる。また、この実施形態では、外向きフランジ部12の外形は十角形に形成されているが、五角形以上の適宜の多角形状に設けられていればよい。
なお、この枠部10の外縁部及び内縁部(開口部14の内周縁部)は、アルミニウム箔の端縁を丸めた縁巻き状態に形成されている。
As shown in FIG. 1, the frame portion 10 is formed of an aluminum foil, and an outward flange portion 12 extending radially outward of the cylindrical portion 11 is integrally formed with one end of the cylindrical cylindrical portion 11. At the other end of the tubular portion 11, an inward flange portion 13 extending inward in the radial direction of the tubular portion 11 is integrally formed. The inside of the inward flange portion 13 is an opening 14. Moreover, in this embodiment, although the external shape of the outward flange part 12 is formed in the decagon, it should just be provided in the appropriate polygonal shape more than a pentagon.
In addition, the outer edge part and inner edge part (inner peripheral edge part of the opening part 14) of this frame part 10 are formed in the edge winding state which rounded the edge of aluminum foil.

枠部10の開口部14の内面側には、不織布フィルター20がヒートシール等の接着手段等により設けられ、この不織布フィルター20により開口部14全体が覆われている。不織布フィルター20は、難燃性不織布を材料として適宜の厚さに設けられる。
さらに、開口部14には、帯状の補強部15が略十字形状に架け渡し状態で枠部10と一体に設けられ、この補強部15によって枠部10の中央部分が補強されている。この補強部15により、開口部14は4個に分割して設けられる。
A nonwoven fabric filter 20 is provided on the inner surface side of the opening portion 14 of the frame portion 10 by an adhesive means such as heat seal, and the entire opening portion 14 is covered with the nonwoven fabric filter 20. The nonwoven fabric filter 20 is provided with an appropriate thickness using a flame-retardant nonwoven fabric as a material.
Further, a band-shaped reinforcing portion 15 is provided in the opening 14 so as to be integrated with the frame portion 10 in a substantially cross-shaped state, and the central portion of the frame portion 10 is reinforced by the reinforcing portion 15. By this reinforcing portion 15, the opening 14 is divided into four parts.

図2に示すように、枠部10外周の外向きフランジ部12の一部には、180°対向する位置に突出部16が形成され、この突出部16の裏面に磁石17が取り付けられており、これら突出部16及び磁石17により、ファンの金属面に着脱するための取付部18を構成している。この磁石17は突出16に両面テープによる貼り付け、或はプラスチック製のリベットにより固着されている。   As shown in FIG. 2, a protruding portion 16 is formed at a position opposed to 180 ° on a part of the outward flange portion 12 on the outer periphery of the frame portion 10, and a magnet 17 is attached to the back surface of the protruding portion 16. The projecting portion 16 and the magnet 17 constitute an attaching portion 18 for attaching to and detaching from the metal surface of the fan. The magnet 17 is fixed to the protrusion 16 with a double-sided tape or a plastic rivet.

そして、このファン用フィルター1は、図3に示した店頭陳列用の包装用袋等の包装具30内に収納される。包装具30は、例えばポリエチレンによって形成され、枠部10を収納し得る大きさの正面視四角形状の偏平な袋部である収納部31と、該収納部31の上端に連設され、引掛け用の孔部32を有するヘッダ部33とからなっている。   The fan filter 1 is accommodated in a packaging tool 30 such as a packaging bag for store display shown in FIG. The packaging tool 30 is formed of, for example, polyethylene, and is connected to the storage portion 31 that is a flat bag portion having a rectangular shape in front view and capable of storing the frame portion 10, and the upper end of the storage portion 31. And a header portion 33 having a hole portion 32 for use.

収納部31の底辺35には、枠部10の外向きフランジ部12の任意の一辺12aが対向しつつ収納部31の両側辺36により枠部10の側部12bが位置規制されており、これによって枠部10が収納部31内で回転不能の状態で収納されている。本実施形態の場合、枠部10の側部12bは、外向きフランジ部12の角部が相当する。
包装具30は、スーパー等の小売店において、ファン用フィルター1が収納された状態で、孔部32を商品陳列用フック(図示略)に引っ掛けて、フックからぶら下げた状態で陳列されるようになっている。
The bottom side 35 of the storage part 31 is opposed to the arbitrary side 12a of the outward flange part 12 of the frame part 10 while the side part 12b of the frame part 10 is regulated by the side edges 36 of the storage part 31. Thus, the frame portion 10 is stored in the storage portion 31 in a non-rotatable state. In the case of this embodiment, the side portion 12b of the frame portion 10 corresponds to a corner portion of the outward flange portion 12.
The packaging tool 30 is displayed at a retail store such as a supermarket in a state where the fan filter 1 is stored and the hole 32 is hooked on a product display hook (not shown) and is hung from the hook. It has become.

続いて、本発明のファン用フィルター1の上記実施形態における作用を説明する。
本発明のファン用フィルター1は、レンジフード内のファンの吸い込み口を覆うように取り付けられ、枠体10の左右の取付部18の磁石17をレンジフードの鉄製のハウジング表面に吸着させることにより、レンジフードに取り付けることができる。このファン用フィルター1は、枠部10、不織布フィルター20がパーツごとに分かれることなく一体に設けられているとともに、取付部18も枠部10に一体に設けられているため、組み合わせ作業を要することなくファンの吸い込み口側にワンタッチで簡単に取付けることができ、作業が煩雑になることなく頭上に設定されたレンジフードにも容易に取り付けでき、作業者の負担が抑えられる。
Then, the effect | action in the said embodiment of the filter 1 for fans of this invention is demonstrated.
The fan filter 1 of the present invention is attached so as to cover the suction port of the fan in the range hood, and by adsorbing the magnets 17 of the left and right attachment portions 18 of the frame 10 to the iron housing surface of the range hood, Can be attached to the range hood. This fan filter 1 requires a combination work because the frame portion 10 and the nonwoven fabric filter 20 are integrally provided without being separated for each part, and the attachment portion 18 is also integrally provided in the frame portion 10. It can be easily attached to the fan inlet with a single touch, and can be easily attached to a range hood set overhead, without complicating work, thereby reducing the burden on the operator.

また、このファン用フィルター1は前述したようにスーパー等でフックに引っ掛けて陳列されるが、枠部10の外形が五角形以上の多角形状であり、この枠部10における任意の一辺12aが包装具30の底辺35側に対向した状態で収納されているため、陳列状態から垂直に落下した場合には、底辺35から接地してこれに沿うように枠部10の一辺12aが線接触状態で接地することになり、力が分散されるため、枠部10の変形や潰れを防止することができる。
一方、包装具30が傾いた状態で収納部31の底辺35と側辺36との間の角部37を下にして落下した場合には、この角部37から離れた位置に枠部10の辺12cが傾斜して配置され、その角部37には位置していないため、その衝撃力が収納部31によって吸収されるために枠部10の変形や潰れが防止される。
As described above, the fan filter 1 is displayed by being hooked by a supermarket or the like, but the outer shape of the frame portion 10 is a polygonal shape of a pentagon or more, and an arbitrary side 12a in the frame portion 10 is a packaging tool. 30 is stored in a state of being opposed to the bottom 35 side, so that when it falls vertically from the display state, it grounds from the bottom 35 and the one side 12a of the frame portion 10 is grounded in a line contact state along this. As a result, since the force is dispersed, the frame portion 10 can be prevented from being deformed or crushed.
On the other hand, when the packaging tool 30 is tilted and dropped with the corner portion 37 between the bottom side 35 and the side portion 36 of the storage unit 31 facing down, the frame portion 10 is positioned away from the corner portion 37. Since the side 12c is inclined and not positioned at the corner portion 37, the impact force is absorbed by the storage portion 31, so that the frame portion 10 is prevented from being deformed or crushed.

このため、衝撃吸収用の台紙を必要とすることなく、アルミニウム合金材料で形成された枠部10の変形や潰れが軽減される。
枠部10の外形が五角形以上であれば、収納部31の底辺35に枠部10の一辺が平行になり、その一辺の両隣の辺が収納部31の底辺35に対して傾斜した配置となるから、収納部31の角部37では枠部10の辺が傾斜して配置され、落下の際に上述した作用を奏することができる。この枠部10の外形は六角形以上、十二角形以下がより好ましい。
ただし、全体としては四角形の外形であっても、その角部が丸く面取りされ、正面視四角形状の包装具の収納部に収納したときに、収納部の底辺に対して面取り部が実質的に傾斜した配置となる場合にも、本発明を適用することができる。
For this reason, the deformation | transformation and crushing of the frame part 10 formed with the aluminum alloy material are reduced, without requiring the mount for shock absorption.
If the outer shape of the frame portion 10 is a pentagon or more, one side of the frame portion 10 is parallel to the bottom side 35 of the storage portion 31, and both sides of the one side are inclined with respect to the bottom side 35 of the storage portion 31. Therefore, the corners 37 of the storage part 31 are arranged with the sides of the frame part 10 inclined, so that the above-described action can be achieved during the fall. The outer shape of the frame 10 is more preferably a hexagon or more and a dodecagon or less.
However, even if the overall shape is a quadrangle, the corners are rounded and chamfered so that the chamfered portion is substantially the same as the bottom of the storage unit when stored in the storage unit of a rectangular package in front view. The present invention can also be applied to an inclined arrangement.
