【発明の属する技術分野】
本発明はロール状に巻かれた食品等包装用のラップフィルム(合成樹脂フィルムのほか、アルミホイール、クッキングペーパー等を含む)を収納し、必要量ずつ引き出してカットするラップフィルムの収納箱に関するものである。
【0002】
【従来の技術】
従来、ラップフィルムの収納箱は、図6,7に示すように、上面が開口した箱本体Aと、この箱本体Aの上面開口部を開閉する蓋Bとによって細長の直方体状に構成されている。
【0003】
箱本体Aは、底面板1と、前面板2と、後面板3と、左右両側面板4,4とによって形成されている。
【0004】
ここで、左右両側面板4,4は、図7に示すように前、後面板2,3の左右両側に延設された折り返し片5,6同士を重ね合せて接着し、さらにその外側に、底面板1の左右両側に連設された折り返し片7を重ね合せ接着することによって形成される。
【0005】
また、前面板2の上端に飛び出し防止フラップ8が内向きに一体に延設され、この飛び出し防止フラップ8によって使用時(とくにフィルム引出し時)のロール状フィルムの箱外への飛び出しが防止される。
【0006】
一方、蓋Bは、前板9と、上板10と、左右両側板11,11とによって形成され、前板9の下端にフィルム切断用の鋸歯付きカッター12が取付けられている。
【0007】
このラップフィルムの収納箱は、使用中は、中身のフィルムを保護するとともに、カッター12によってフィルムを切断し易くするという観点から十分堅牢であることが望まれる。
【0008】
ところが、従来のフィルム収納箱によると、堅牢に形成されることで、使用後に廃棄する際に、とくに本体Aにおける前面板2と左右両側面板4,4とによって形成される前側角部C1,C1が堅くて本体Aが扁平につぶれ難く、社会的ニーズである包装廃棄物の減容化に応えられなかった。
【0009】
そこで、図7に示すように、箱本体Aの左右両側面板4,4を構成する前、後面板2,3の折り返し片5,6に予めミシン目(切断線)13,14を入れておき、廃棄時にこのミシン目13,14により両折り返し片5,6を切断して側面板4,4全体として外側に開き、箱本体Aの扁平化を可能とした技術が提案された(特開平9−2484号公報参照)。
【0010】
【発明が解決しようとする課題】
ところが、この公知技術によると、使用中もミシン目13,14によって折り返し片5,6が半ば切断された状態にあるため、側面板4,4が脆弱化し、箱本体Aの強度が低下して変形、破損し易くなるという弊害が生じていた。
【0011】
また、扁平化の前段階として、両側面板4,4の折り返し片5,6を破断するというこれまでにない特別な操作が必要となり、かつ、この操作が必要であることを使用者に認識させなければならない。
【0012】
従って、操作が面倒となり、あるいは認識不足によってこの操作が実行されずに、結局、減容化がなし得ない可能性があった。
【0013】
そこで本発明は、使用中の強度を落さず、しかも、廃棄時には簡単かつ自然な操作によって箱を扁平化することができるラップフィルムの収納箱を提供するものである。
【0014】
【課題を解決するための手段】
請求項1の発明は、ロール状に巻かれたラップフィルムが収納される上面が開口した箱本体と、この箱本体の上面開口部を開閉する蓋とによって構成され、上記箱本体は、底面板と前面板と後面板と左右両側面板とから成るラップフィルムの収納箱において、上記箱本体における左右両側の前側角部を形成する上記前面板の左右両端部と上記左右両側面板に、上記前側角部を含む本体左右両端部を内側に扁平に折り込むための折目が設けられ、上記左右両側面板の折目は、箱本体の前側角部の上端と後側角部の下端とを結ぶ対角線上に設けられ、上記前面板の折目は、上記前側角部の下端を一端として上記左右両側面板の折目とほぼ平行に設けられたものである。
【0015】
請求項2の発明は、請求項1の構成において、蓋が、箱本体の後面板に連続する上板と、この上板の前端に下向きに連続する前板と、左右両側板とによって構成され、この蓋における前板の左右両端部に、蓋の前側角部を含む蓋左右両端部を内側に扁平に折り込むための折目が、蓋の前側角部の上端から前板下端までの間に傾斜して設けられものである。
【0016】
請求項3の発明は、請求項1または2の構成において、箱本体における前面板の上端に飛び出し防止フラップが内向きに一体に延設され、前面板の折目がこの飛び出し防止フラップに至らない範囲で設けられたものである。
【0017】
請求項4の発明は、請求項1乃至3のいずれかの構成において、本体における左右両側面板が、底面板、前面板、後面板の各左右両端に連設された折り返し片同士が重ね合せ 状態で接着されて形成され、この各折り返し片に折目が上記重ね合せ状態で一致する状態で設けられて側面板の折目が形成されたものである。
【0018】
上記構成によると、使用後の廃棄に際して、箱本体の前側角部を内側に押し込めば、この角部を含む本体両端部が折目により内向きに折り込まれて本体が扁平に折り畳まれる。
【0019】
この場合、両側面板の折目を、前側角部の上端と後側角部の下端とを結ぶ対角線上に設け、前面板の折目をこの側面板の折目とほぼ平行に設けているため、側面板全体が対角線上で二つ折れに内折れし、前面板の両端部がこれと一体に内向きに折り畳まれる。
【0020】
すなわち、前側角部を含む本体の左右両端部を、余分な抵抗なしに自然に、かつ、無理なくコンパクトに折畳むことができる。
【0021】
この操作は、折目の有無に関係なく、従来から廃棄に際して使用者が自然に行っていた操作であって、公知技術のように一部を破断するというこれまでにない特別な操作を行う必要がない。すなわち、簡単かつ自然な操作によって箱を扁平化することができる。
【0022】
しかも、前側角部を形成する前面板と側面板(請求項では底面、前面、後面各板の折り返し片)に折目を入れておくだけでよいため、使用時の強度低下を招かない。
【0023】
一方、請求項の構成によると、蓋の両端部を折目により内側に折り込んで蓋をも扁平化し、箱全体を板紙の二つ折りに近い状態としてさらに減容化することができる。
【0024】
また、請求項の構成によると、飛び出し防止フラップを備えた収納箱において、本体前面板の折目がこの飛び出し防止フラップまでは及んでいないため、使用中、同フラップが折目によって外側に膨らんだり曲がったりして本来の飛び出し防止機能が低下するおそれがない。
【0025】
【発明の実施の形態】
本発明の実施形態を図1〜図5によって説明する。
【0026】
図1にこのラップフィルムの収納箱の組立前の展開状態、図2に組立状態をそれぞれ示している。
【0027】
図1において、21は底面板、22は前面板、23は後面板で、これら各板21,22,23の長さ方向(左右)両端にそれぞれ折り返し片24,25,26が一体に連設され、組立時に、左右両側において図3に示すようにこれら各折り返し片24,25,26が内外に重ね合せ接着されて側面板27,27が形成され、かつ、図2に示す上面が開口した箱本体Dが構成される。
【0028】
図1,2中、28は前面板22の一端(組立状態での上端)にほぼ全幅に亘って一体に延設された飛び出し防止フラップである。
【0029】
一方、図1において、29は蓋上板、30は蓋前板で、これらの左右両端にそれぞれ折り返し片31,32が一体に連設され、組立時に、左右両側においてこれら両折り返し片31,32同士が内外に重ね合せ接着されて蓋側板33,33が形成され、かつ、図2に示すように箱本体Dの上面開口部を開閉する蓋Eが構成される。
【0030】
図1,2中、34は蓋前板30に取付けられたフィルム切断用の鋸歯付きカッター、35はこのカッター34を外側から覆うカッター覆い片で、使用時にこのカッター覆い片35が取り除かれてカッター34が露出する。
【0031】
また、図1中、a…は隣り合う板間、および板と折り返し片との間に設けられた組立用の折目である。
【0032】
この収納箱においては、使用後の廃棄時に箱全体を扁平に折畳むための折目が箱本体Dおよび蓋Eに設けられている。
【0033】
箱本体Dの折目
箱本体Dを扁平化する際、最も障害となるのは、前面板22の両端部と側面板27,27とによって形成される堅くて変形し難い左右の前側角部C2,C2である。
【0034】
そして、従来から廃棄時の扁平化の手始めにこの前側角部C2,C2を押し潰す操作が自然に行われていた。
【0035】
そこで、両側の側面板27,27において、前側角部C2,C2の上端と後側角部C3,C3の下端とを結ぶ対角線上に折目(以下、側面折目という)b1,b1が設けられている。
【0036】
ここで、側面板27,27は、前記のように底面、前面、後面の各板21,22,23の折り返し片24,25,26が重ね合せ接着されることによって形成されている。
【0037】
このため、図1,3に示すようにこれら各折り返し片24,25,26ごとに折目b1´が設けられ、組立時にこれらが一致して一つの側面折目b1が形成されるようになっている。
【0038】
また、前面板22の左右両側に、折目(以下、前面折目という)b2,b2が、前側角部C2,C2の下端を一端として、側面折目b1,b1とほぼ平行(完全平行またはそれに近い状態)となるように傾斜して設けられている。
【0039】
この場合、使用中、飛び出し防止フラップ28がこの前面折目b2,b2によって外側に膨らんだり曲がったりして本来の飛び出し防止機能が低下することのないように、前面折目b2,b2は同フラップ28までは至らずに前面板22の範囲のみに設けられている。
【0040】
蓋Eの折目
蓋Eは、前板30と両側の側板33,33とによって形成される前側角部C4,C4を内側に押し潰すことによって扁平化することができる。
【0041】
そこで、前板30の左右両端部において、前側角部C4,C4の上端から前板下端に至る傾斜した折目(以下、蓋折目という)b3,b3が設けられている。
【0042】
この収納箱を、使用後の廃棄に際して扁平化する場合は、図2の二重線矢印イ,イで示すように、箱本体Dの左右の前側角部C2,C2を内側に押圧する。
【0043】
こうすると、図4,5に示すように本体Dの左右両端部において、側面板27が側面折目b1によって内向き二つ折れに、前面板22が前面折目b2によって外折れにそれぞれ同時に折り込まれてフラットに折り畳まれる。
【0044】
この場合、側面折目b1を、前側角部C2の上端と後側角部C3の下端とを結ぶ対角線上に設け、前面折目b2をこの側面折目b1とほぼ平行に設けているため、前側角部C2を含む本体左右両端部を、余分な抵抗なしに自然に、かつ、無理なくコンパクトに折畳むことができる。
【0045】
また、蓋Eの前側角部C4,C4を内向きに押すと、蓋折目b3,b3によって蓋Eの両端部が内側に折り込まれて蓋Eも扁平となる。
【0046】
これにより、箱全体を扁平なほぼ二つ折れ状態に折り畳むことができる。
【0047】
このように本体Dおよび蓋Eの前側角部C2,C4を内側に押圧するという、従来から廃棄に際して使用者が自然に行っていた操作、すなわち図7に示す公知技術のようにミシン目13,14によって一部を破断するというこれまでにない特別な操作を要せずに、簡単かつ自然な操作によって箱を容易に扁平化することができる。
【0048】
しかも、前側角部C2,C4を形成する板(本体Dの側面板27と前面板22、蓋Eの前板30)に折目b1,b2,b3を入れておくだけでよいため、ミシン目を入れた場合のように使用時に強度が低下して変形、破損し易くなるという弊害が生じない。
【0049】
ところで、上記実施形態では、箱本体Dだけでなく蓋Eにも折目b3を設けて蓋Eの扁平化を助けるように構成したが、この蓋Eの側板33は後端がフリーとなっていて、元々、蓋両端部は本体両端部と比較して扁平化させ易いため、この蓋折目b3は必要に応じて設ければよい。
【0050】
また、上記実施形態では、本体側面板27が底面、前面、後面の各板21,22,23の折り返し片24,25,26を重ね合せ接着することによって形成される箱を例示したが、この側面板27が二つまたは一つの折り返し片によって形成される箱にも適用し得ることはいうまでもない。
【0051】
【発明の効果】
上記のように本発明によるときは、箱本体における左右両側の前側角部を形成する前面板の左右端部と側面板に折目を設け、使用後の廃棄時に、この折目により本体左右両端部を内側に折り込んで本体全体を扁平化し得るように構成したから、本体前側角部を内側に押圧するという、従来から廃棄に際して使用者が自然に行っていた操作のみによって簡単に箱本体を扁平化(減容化)することができる。
【0052】
この場合、両側面板の折目を、前側角部の上端と後側角部の下端とを結ぶ対角線上に設け、前面板の折目をこの側面板の折目とほぼ平行に設けているため、前側角部を含む本体の左右両端部を、余分な抵抗なしに自然に、かつ、無理なくコンパクトに折畳むことができる。
【0053】
一方、請求項の発明によると、蓋の両端部を折目により内側に折り込んで蓋をも扁平化し、箱全体を板紙の二つ折りに近い状態としてさらに減容化することができる。
【0054】
また、請求項の発明によると、飛び出し防止フラップを備えた収納箱において、本体前面板の折目がこの飛び出し防止フラップまでは及んでいないため、使用中、同フラップが折目によって外側に膨らんだり曲がったりして本来の飛び出し防止機能が低下するおそれがない。

BACKGROUND OF THE INVENTION
The present invention relates to a wrapping film storage box for storing a wrapping film (including synthetic resin film, aluminum wheels, cooking paper, etc.) wrapped in a roll, and pulling out and cutting the necessary amount. It is.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 6 and 7, a wrap film storage box is formed in an elongated rectangular parallelepiped shape by a box body A having an upper surface opened and a lid B for opening and closing the upper surface opening of the box body A. Yes.
[0003]
The box body A is formed by a bottom plate 1, a front plate 2, a rear plate 3, and left and right side plates 4 and 4.
[0004]
Here, as shown in FIG. 7, the left and right side plates 4, 4 are overlapped and bonded together by folding pieces 5, 6 extending on the left and right sides of the front and rear plates 2, 3, and on the outside thereof, It is formed by overlapping and adhering folded pieces 7 connected to the left and right sides of the bottom plate 1.
[0005]
Further, a pop-out prevention flap 8 is integrally extended inward at the upper end of the front plate 2, and the pop-out prevention flap 8 prevents the roll-shaped film from jumping out of the box during use (particularly when the film is pulled out). .
[0006]
On the other hand, the lid B is formed by a front plate 9, an upper plate 10, and left and right side plates 11, 11, and a saw-toothed cutter 12 for film cutting is attached to the lower end of the front plate 9.
[0007]
The wrap film storage box is desired to be sufficiently robust from the viewpoint of protecting the film inside and making the film easy to cut by the cutter 12 during use.
[0008]
However, according to the conventional film storage box, the front side corners C1 and C1 formed by the front plate 2 and the left and right side plates 4 and 4 in the main body A, especially when discarded after use, are formed firmly. However, the main body A was hard to flatten and could not meet the social needs of volume reduction of packaging waste.
[0009]
Therefore, as shown in FIG. 7, before constructing the left and right side plates 4 and 4 of the box body A, perforations (cut lines) 13 and 14 are put in the folded pieces 5 and 6 of the rear plates 2 and 3 in advance. A technique has been proposed in which both folded pieces 5 and 6 are cut by the perforations 13 and 14 at the time of disposal and opened to the outside as the entire side plates 4 and 4 so that the box body A can be flattened (Japanese Patent Laid-Open No. Hei 9). -2484).
[0010]
[Problems to be solved by the invention]
However, according to this known technique, since the folded pieces 5 and 6 are half cut by the perforations 13 and 14 even during use, the side plates 4 and 4 are weakened and the strength of the box body A is reduced. There was an adverse effect of being easily deformed and damaged.
[0011]
Also, as a pre-stage of flattening, the user needs to recognize a special operation that is unprecedented, such as breaking the folded pieces 5 and 6 of the side plates 4 and 4, and that this operation is necessary. There must be.
[0012]
Therefore, there is a possibility that the operation is troublesome or the operation is not executed due to lack of recognition, and the volume cannot be reduced after all.
[0013]
Therefore, the present invention provides a wrapping film storage box that does not reduce the strength during use and that can be flattened by a simple and natural operation when discarded.
[0014]
[Means for Solving the Problems]
The invention according to claim 1 is constituted by a box main body having an open upper surface in which a wrap film wound in a roll shape is accommodated, and a lid for opening and closing the upper surface opening of the box main body. and the storage box wrap film made of a front plate and a rear plate and left and right side plates, the left and right ends of the front plate and the right and left side plates which form the front corners of the left and right sides of the box body, the front corner folds for folding the flat body left and right ends inside the set vignetting containing part, fold the left and right side plates are diagonal connecting the lower end of the upper and rear corners of the front corner portion of the box body The folds of the front plate provided above are provided substantially parallel to the folds of the left and right side plates with the lower end of the front side corner as one end .
[0015]
According to a second aspect of the present invention, in the configuration of the first aspect , the lid is constituted by an upper plate that continues to the rear plate of the box body, a front plate that continues downward from the front end of the upper plate, and left and right side plates. The folds for flatly folding the left and right ends of the lid including the front corners of the lid inwardly on the left and right ends of the front plate of the lid are between the upper end of the front corner of the lid and the lower end of the front plate. It is provided with an inclination .
[0016]
According to a third aspect of the present invention, in the configuration of the first or second aspect , the pop-out prevention flap is integrally extended inward at the upper end of the front plate in the box body , and the fold of the front plate does not reach the pop-out prevention flap. It is provided in a range .
[0017]
The invention according to claim 4, in the construction of claims 1 to 3, the left and right side surfaces plate of the box body, a bottom plate, front plate, folded piece together provided continuously to each right and left ends of the rear surface plate is superposed It is formed by bonding in a state, and the folds of the side plates are formed by providing the folded pieces with the folds coincided with each other in the overlapping state .
[0018]
According to the above configuration, if the front corner of the box main body is pushed inward at the time of disposal after use, both ends of the main body including the corner are folded inward by the folds, and the main body is folded flat.
[0019]
In this case, the folds of the side plates are provided on a diagonal line connecting the upper end of the front corner and the lower end of the rear corner, and the fold of the front plate is provided substantially parallel to the fold of the side plate. The entire side plate is folded in two diagonally, and both end portions of the front plate are folded inward integrally with the side plate.
[0020]
That is, it is possible to fold the left and right ends of the main body including the front side corners in a compact and natural manner without excessive resistance.
[0021]
Regardless of whether there is a fold or not, this operation has been performed naturally by the user at the time of disposal, and it is necessary to perform an unprecedented special operation such as breaking a part as in the known art. There is no. That is, the box can be flattened by a simple and natural operation.
[0022]
In addition, since it is only necessary to make a crease in the front plate and the side plate forming the front corner (the folded pieces of the bottom plate, the front plate, and the rear plate in claim 4 ), the strength is not lowered during use.
[0023]
On the other hand, according to the configuration of the second aspect , both ends of the lid are folded inward by folds to flatten the lid, and the entire box can be further reduced to a state close to a half-fold of paperboard.
[0024]
According to the configuration of claim 3 , in the storage box provided with the pop-out prevention flap, the fold of the main body front plate does not reach the pop-out prevention flap. There is no risk of the original pop-out prevention function from being lowered due to bending or bending.
[0025]
