Description

本考案は野菜、果物等主として生鮮食品等を収納し、積み重ねができる段ボールケースに関するものである。   The present invention relates to a corrugated cardboard case that can store and stack fresh foods such as vegetables and fruits.

従来、この種の段ボールケースは上面が開放され、生鮮食品等を収納して複数個積み重ねて保管したり、運搬を行っており、潰れたり、曲がったりしないように、一般に四隅の上端を補強している。
この補強の手段としては、上面の四隅に三角状の連結片を設けたり、前後側壁の上端に補強片を連設して上面側へ折り曲げて桟を形成した（特許文献１参照）ものが一般的である。 Conventionally, this type of corrugated cardboard case has an open top surface, and stores and transports fresh foods, etc., and transports them. In general, the upper ends of the four corners are reinforced to prevent crushing or bending. ing.
As a means of reinforcement, a triangular connecting piece is provided at the four corners of the upper surface, or a reinforcing piece is connected to the upper end of the front and rear side walls and bent to the upper surface side to form a crosspiece (see Patent Document 1). Is.

特許文献１の段ボールケース３００は、図７に示すように、底面１１から立設される左右側壁１２Ａに内側壁片１４を連設し、これを直角に折り曲げて側壁片１３を立ち上げ、側壁片１３に連設した補強帯１５を折り曲げて上面および側面を巻回し補強している。なお、１５ｃは左右側壁１２Ａの下端に設けた差込溝１２ｃに差し込まれる差込片である。
この段ボールケース３００は積み重ねたとき、上段の段ボールケース３００は上面の補強帯１５に載り、面で支持されるので、下段の段ボールケースへ落ち込んだり、荷崩れすることが防止される。なお、左右側壁１２Ａの上端中央には凸片１２ａが設けられており、段積みする際のズレや荷崩れを防止している。 As shown in FIG. 7, the corrugated cardboard case 300 of Patent Document 1 has inner wall pieces 14 connected to left and right side walls 12 </ b> A that are erected from the bottom surface 11, and is bent at a right angle to raise the side wall pieces 13. The reinforcing band 15 provided continuously with the piece 13 is bent and the upper surface and side surfaces are wound and reinforced. In addition, 15c is an insertion piece inserted in the insertion groove 12c provided in the lower end of 12 A of right-and-left side walls.
When the corrugated cardboard cases 300 are stacked, the upper corrugated cardboard case 300 rests on the upper reinforcing band 15 and is supported by the surface, so that the cardboard case 300 is prevented from falling into the lower corrugated cardboard case and collapsed. In addition, the convex piece 12a is provided in the upper-end center of 12 A of right-and-left side walls, and the shift | offset | difference and load collapse at the time of stacking are prevented.

特開２００５-１５００９号Japanese Patent Application Laid-Open No. 2005-15009

特許文献１の段ボールケース３００は、前後側壁片１３の上端に連設された補強帯１５が外れないように左右側壁１２Ａの端部に沿わせてその下端で固設し、積み重ねた段ボールケースは補強帯１５の幅で支持されるので、潰れが防止される。
しかしながら、この補強帯１５は、前後側壁片１３に連設され、左右側壁１２Ａの上端に支持されているだけなので、積み重ねる段ボールケースの重量が大きい場合には、複数個重ねると下の方では補強帯１５の撓みが大きくなり、傾くことがある。 The corrugated cardboard case 300 of Patent Document 1 is fixed at the lower end along the ends of the left and right side walls 12A so that the reinforcing band 15 connected to the upper end of the front and rear side wall pieces 13 is not detached. Since it is supported by the width of the reinforcing band 15, crushing is prevented.
However, the reinforcing band 15 is connected to the front and rear side wall pieces 13 and is supported only at the upper ends of the left and right side walls 12A. The band 15 may bend and be tilted.

そこで本考案は補強帯の支持力を高め、安定した積み重ねができる段ボールケースを提供することを目的としている。   Therefore, the present invention aims to provide a corrugated cardboard case that can increase the supporting force of the reinforcing band and can be stably stacked.

上記の目的を達成するため、本考案の段ボールケースは、次のように構成した。すなわち、一枚の段ボールに、矩形の底面の四辺に対向して左右側壁片と前後側壁片が連設され、該左右側壁片には前後側壁片の前部に配置される内側壁片が連設されるとともに積み重ねられた段ボールケースの前後方向の位置を規制するための凸片が設けられ、該前後側壁片には前後側壁の上端に連設され上面から左右側壁片に沿って巻回される補強帯が連設され、これを折り目に沿って折り曲げて組み立てられる段ボールケースにおいて、該左右側壁片の長さは底面１の左右の長さより短くし、該内側壁片は四隅において左右側壁片から前後側壁の前部へ斜めに配置される斜折部４ａを備えるとともに、該内側壁片の先端側に対向する内側壁片同士を連結するための掛止溝４ｂを設けたことを特徴としている。   In order to achieve the above object, the cardboard case of the present invention is configured as follows. That is, the left and right side wall pieces and the front and rear side wall pieces are continuously provided on one cardboard so as to face the four sides of the rectangular bottom surface, and the left and right side wall pieces are connected to the inner side wall pieces arranged in front of the front and rear side wall pieces. Protruding pieces are provided for restricting the position in the front-rear direction of the corrugated cardboard cases that are installed and stacked, and the front and rear side wall pieces are connected to the upper ends of the front and rear side walls and are wound from the upper surface along the left and right side wall pieces. In the corrugated cardboard case, the left and right side wall pieces are shorter than the left and right lengths of the bottom surface 1, and the inner side wall pieces are arranged at the four corners. And a hooking groove 4b for connecting the inner wall pieces facing each other to the front end side of the inner wall piece. Yes.

この段ボールケースは、従来の段ボールケース（例えば、特許文献１）を安定した積み重ねができるように改良したもので、特に四隅の上端部の補強帯の支持力が大きくなるように構成したものである。
すなわち、この考案では、四隅の上端部の補強帯は、前後側壁片の内側に配置された斜折部４ａによって支持されるので、支持力が大きくなった。
ケースの四隅に斜めの壁を形成する斜折部４ａは、寸法を特に制限しないが、隅部を４５度にカットするように配置するのが望ましい。
さらに、積み重ねの支持力を高める手段として、請求項２に記載のように、左右側壁片は、左右側壁の上端に前記凸片２ａを跨いでケース内側へ水平に折リ曲げられる補強片を設けて左右側壁片でも重量を負担するように構成するとよい。 This corrugated cardboard case is an improvement of a conventional corrugated cardboard case (for example, Patent Document 1) so that it can be stably stacked. In particular, the corrugated cardboard case is constructed so that the supporting force of the reinforcing band at the upper end of the four corners is increased. .
That is, in this device, since the reinforcing bands at the upper end portions of the four corners are supported by the inclined portions 4a disposed inside the front and rear side wall pieces, the supporting force is increased.
The slanted folds 4a that form slanted walls at the four corners of the case are not particularly limited in size, but are preferably arranged so that the corners are cut at 45 degrees.
Furthermore, as means for increasing the supporting force for stacking, as described in claim 2, the left and right side wall pieces are provided with reinforcing pieces that are bent horizontally inside the case across the convex pieces 2a at the upper ends of the left and right side walls. The left and right side wall pieces may be configured to bear the weight.

本考案の段ボールケースは、底面の四辺に連設された左右側壁片には前後側壁片の前部に配置される内側壁片が連設されるとともに積み重ねられた段ボールケースの前後方向の位置を規制するための凸片が設けられ、前後側壁片には上端に左右側壁片に沿って巻回される補強帯が連設され、該左右側壁片の長さは底面１の左右の長さより短くし、該内側壁片は四隅において左右側壁片から前後側壁の前部へ斜めに配置される斜折部４ａを備えるとともに、該内側壁片の先端側に対向する内側壁片同士を連結するための掛止溝４ｂを設けたので、積み重ね時の補強帯にかかる荷重は、大半が内側壁片で支持され、しかも、内側壁片は互いに固く連結されているので、段ボールケースの積み重ねが安定したものとなる。
また、請求項２に記載のように、前記左右側壁片は、左右側壁の上端に前記凸片２ａを跨いでケース内側へ水平に折リ曲げられる補強片を設ければ、積み重ねた段ボールケースは左右側壁でも分担支持するので、より安定した積み重ねができる。 In the cardboard case of the present invention, the left and right side wall pieces provided continuously on the four sides of the bottom surface are provided with inner side wall pieces arranged in front of the front and rear side wall pieces and the positions of the stacked cardboard cases in the front and rear direction are determined. Protruding pieces for regulating are provided, and reinforcing bands wound along the left and right side wall pieces are connected to the front and rear side wall pieces, and the length of the left and right side wall pieces is shorter than the left and right lengths of the bottom surface 1. In addition, the inner wall piece includes a slanted portion 4a that is disposed obliquely from the left and right side wall pieces to the front part of the front and rear side walls at the four corners, and connects the inner wall pieces facing the front end side of the inner wall piece. Since the retaining groove 4b is provided, most of the load applied to the reinforcing band during stacking is supported by the inner wall pieces, and the inner wall pieces are firmly connected to each other, so that the stacking of the cardboard cases is stable. It will be a thing.
Further, as described in claim 2, if the left and right side wall pieces are provided with reinforcing pieces that can be bent horizontally inside the case across the convex pieces 2a at the upper ends of the left and right side walls, Since the left and right side walls are also shared and supported, more stable stacking is possible.

FIG. 3 is a perspective view showing a state in the middle of assembling the cardboard 100 into the cardboard case 200, and FIG. 4 is a perspective view showing a state in which the cardboard cases 200 are stacked.

段ボールケース２００は、図１に示すように、底面１の四方に左右側壁２Ａと前後側壁３Ａとが立設されて上面が開放された直方体に形成され、前後側壁３Ａの上端に一部上面を覆う補強帯５が連設されている。 この補強帯５は、前後側壁３Ａから内側へ折り曲げて段ボールケースの前後側壁３Ａ寄りの上面を覆い、さらに側面左右側壁２Ａへ沿って巻回して取り付けられている。   As shown in FIG. 1, the corrugated cardboard case 200 is formed in a rectangular parallelepiped shape in which left and right side walls 2A and front and rear side walls 3A are erected on four sides of the bottom surface 1, and the upper surface is opened. A reinforcing band 5 is continuously provided. The reinforcing band 5 is bent inward from the front and rear side walls 3A to cover the upper surface of the cardboard case near the front and rear side walls 3A, and is further wound around the side left and right side walls 2A.

左右側壁２Ａの左右の方向の両端には、前後側壁３Ａの内側へ折れ曲がって設けられる内側壁片４が連設され、前後側壁３Ａの中央で対向する内側壁片４同士を連結している（図３参照）。また、左右側壁２Ａの上端中央には、段ボールケース２００を積み重ねたときに前後方向の位置を外側から規制する凸片２ａが設けられている。
なお、段ボールケース２００の大きさは、ここでは、３１０ｍｍ×５００ｍｍ×１７０ｍｍとしており、補強帯５の幅は１００ｍｍ（上面の中央部は４０ｍｍにカット）としている。 Inner side wall pieces 4 that are bent to the inside of the front and rear side walls 3A are connected to both ends in the left and right direction of the left and right side walls 2A, and connect the inner side wall pieces 4 that face each other at the center of the front and rear side walls 3A ( (See FIG. 3). A convex piece 2a is provided at the center of the upper end of the left and right side walls 2A to restrict the position in the front-rear direction from the outside when the cardboard cases 200 are stacked.
Here, the size of the corrugated cardboard case 200 is 310 mm × 500 mm × 170 mm, and the width of the reinforcing band 5 is 100 mm (the central portion of the upper surface is cut to 40 mm).

この段ボールケース２００は、図２に示した一枚の段ボール１００を、折り目に沿って折り曲げることによって、組み上げられる。   The cardboard case 200 is assembled by folding the single cardboard 100 shown in FIG. 2 along the crease.

段ボール１００は、ほぼ中央に形成された矩形の底面１と、主折り目Ａを介して連設された前後一対の左右側壁片２と、主折り目Ｂを介して連設された前後一対の前後側壁片３とからなり、左右側壁片２には折り目Ｅを介して内側壁片４が、側壁片３には折り目Ｄを介して補強帯５が連設されている。
ここで、折り目Ｅは、底面１の左右端の主折り目Ｂの延長線上ではなく、これより内側（中央寄り）に設けられている。そして、内側壁片４には、折り目Ｅと平行に設けた折り目Ｆを介して、斜折部４ａが設けられている。また、内側壁片４の先端側（側壁片２の反対側）には内側壁片４同士を連結するための掛止溝４ｂが設けられている。
なお、左右側壁片２には、上端中央に凸片２ａ、左右端に突片２ｂが設けられ、左右の下端に差込溝２ｃが設けられている。 The corrugated cardboard 100 includes a rectangular bottom surface 1 formed substantially at the center, a pair of front and rear left and right side wall pieces 2 connected via a main crease A, and a pair of front and rear side walls provided continuously via a main crease B. The inner wall piece 4 is connected to the left and right side wall pieces 2 via a fold E, and the reinforcing band 5 is connected to the side wall piece 3 via a fold D.
Here, the crease E is provided not on the extension line of the main crease B at the left and right ends of the bottom surface 1 but on the inner side (close to the center). The inner wall piece 4 is provided with an oblique fold portion 4a through a fold F provided in parallel with the fold E. Further, a latching groove 4b for connecting the inner wall pieces 4 to each other is provided on the distal end side of the inner wall pieces 4 (opposite side of the side wall pieces 2).
The left and right side wall pieces 2 are provided with a protruding piece 2a at the center of the upper end, a protruding piece 2b at the left and right ends, and an insertion groove 2c at the lower left and right ends.

前後側壁片３は、主折り目Ｂとこれと平行な折り目Ｄと、直角方向の切れ目ａとで矩形状に区画されたもので、前後側壁片３に連設される補強帯５は、前後側壁片３の長さより長く、折り目Ｇによって、上面補強部５ａと側面補強部５ｂに区画される。
上面補強部５ａは中央部に切欠部５ｅが形成され、折り目Ｇ上には、左右側壁片２の突片２ｂが係止する掛止溝５ｄが設けられている。また、側面補強部５ｂには左右側壁片２の差込溝２ｃに係止する差込片５ｃが付設されている。 The front and rear side wall pieces 3 are divided into a rectangular shape by a main crease B, a crease D parallel to the main crease B, and a cut a in a right angle direction. It is longer than the length of the piece 3 and is partitioned by the crease G into an upper surface reinforcing portion 5a and a side surface reinforcing portion 5b.
A cutout portion 5e is formed at the center of the upper surface reinforcing portion 5a, and on the fold line G, a latching groove 5d for engaging the protruding piece 2b of the left and right side wall pieces 2 is provided. Further, the side reinforcing portion 5b is provided with an insertion piece 5c that is engaged with the insertion groove 2c of the left and right side wall pieces 2.

次に、上記のように構成された段ボール１００を、段ボールケース２００へ折り上げる手順について説明する。
底面１を囲むようにして、左右側壁片２、２と前後側壁片３、３をそれぞれ主折り目Ａ、Ｂの位置から起立させるが、先ず、左右側壁片２、２を主折り目Ａの位置から底面１に対して直角に起立させ、次に、折り目Ｅと折り目Ｆから内側へ折り曲げ、上下の内側壁片４の掛止溝４ｂ同士を噛み合わせる。これにより、底面１の四方に左右側壁片２と内側壁片４で繋がった壁が立設され、四隅においては、内側壁片４の斜折部４ａが斜めに傾斜した状態で配置されている（図３参照）。 Next, a procedure for folding the cardboard 100 configured as described above into the cardboard case 200 will be described.
The left and right side wall pieces 2 and 2 and the front and rear side wall pieces 3 and 3 are erected from the positions of the main folds A and B so as to surround the bottom surface 1. First, the left and right side wall pieces 2 and 2 are raised from the position of the main fold line A to the bottom surface 1. , And then folded inward from the folds E and F to engage the retaining grooves 4b of the upper and lower inner wall pieces 4 with each other. As a result, walls connected by the left and right side wall pieces 2 and the inner side wall piece 4 are erected on the four sides of the bottom surface 1, and the inclined portions 4 a of the inner side wall piece 4 are arranged obliquely at four corners. (See FIG. 3).

次いで、前後側壁片３を主折り目Ｂの位置から起立させ、折り目Ｄから内側へ曲げて水平にする。このとき、左右側壁片２の突片２ｂが掛止溝５ｄに差し込まれるようにする。
次に、折り目Ｇからそれぞれ下へ折り曲げ左右側壁片２の左右端に沿わせ、下端の差込片５ｃを差込溝２ｃへ外側から差し込んで固定する。以上の作業で、段ボールケース２００は組み上がる。 Next, the front and rear side wall pieces 3 are erected from the position of the main crease B and bent inward from the crease D to be horizontal. At this time, the protruding pieces 2b of the left and right side wall pieces 2 are inserted into the retaining grooves 5d.
Next, it is bent downward from the crease G, along the left and right ends of the left and right side wall pieces 2, and the insertion piece 5c at the lower end is inserted into the insertion groove 2c from the outside and fixed. With the above operations, the cardboard case 200 is assembled.

図４は、段ボールケース２００を積み重ねた状態を示すもので、上段の段ボールケース２００は、下の段ボールケース２００の左右の補強帯５の上に載置され、補強帯５は、四隅において斜めに配置された斜折部４ａによって支持されているので、重量があっても凹むようなこともなく安定して載置される。また、上段の段ボールケース２００は、左右側壁２Ａの凸片２ａの内側へ嵌入し、前後方向の位置が規制され、複数個積み重ねても所定の位置に載置されるので、偏荷重がかからない。   FIG. 4 shows a state in which the cardboard cases 200 are stacked. The upper cardboard case 200 is placed on the left and right reinforcing bands 5 of the lower cardboard case 200, and the reinforcing bands 5 are slanted at the four corners. Since it is supported by the arranged inclined portion 4a, it is stably placed without being depressed even if it is heavy. Further, the upper corrugated cardboard case 200 is fitted inside the convex pieces 2a of the left and right side walls 2A, the position in the front-rear direction is regulated, and even if a plurality of the cardboard cases 200 are stacked, they are placed at a predetermined position, so that an uneven load is not applied.

次に本考案の別の実施の形態（請求項２）について、図５および図６に基づいて説明する。
図５は、この実施の形態の段ボールケース２１０の全体を示す斜視図で、図６は、段ボールケース２１０の展開図で段ボール１１０である。 Next, another embodiment of the present invention (Claim 2) will be described with reference to FIGS.
FIG. 5 is a perspective view showing the entirety of the cardboard case 210 of this embodiment, and FIG.

段ボールケース２１０は、上記の段ボールケース２００とほとんど同じ構成を備えている。相違する点は、段ボールケース２１０には左右側壁２Ａの上端に内側へ折り曲げられた補強片６が付設されていることである。
この補強片６は左右側壁片２の上端に折り目Ｈで区画され、凸片２ａを跨いで形成されている。
組立は、左右側壁片２を立設するときに折り目Ｈから折り曲げて形成するだけである。
このように構成されているので、段ボールケース２１０を積み重ねると、上段の段ボールケース２１０は、上記と同様に補強帯５に支持されるとともに、左右側壁２Ａの上端の補強片６でも分担して支持されるので、より安定した積み重ねができる。 The corrugated cardboard case 210 has almost the same configuration as the corrugated cardboard case 200 described above. The difference is that the corrugated cardboard case 210 is provided with a reinforcing piece 6 bent inward at the upper ends of the left and right side walls 2A.
The reinforcing piece 6 is defined by a fold H at the upper ends of the left and right side wall pieces 2 and is formed across the convex piece 2a.
The assembly is only formed by folding from the crease H when the left and right side wall pieces 2 are erected.
