Description

本発明は、食品包装などに用いられるラップフィルム等の包装用ウェブを紙管に巻かれた状態で収納するカートンに関するものである。   The present invention relates to a carton for storing a packaging web such as a wrap film used for food packaging in a state of being wound around a paper tube.

従来、この種の包装用ウェブは紙管に巻かれた状態で板紙製のカートンに収納されており、使用に際しては、カートンから所望の長さ分を引き出した後、カートンに付いた金属製の鋸刃により切断して使用するようになっている。ところで、この包装用ウェブを引き出す時に、その勢いやラップフィルム同士の密着による抵抗などにより紙管ごと外に飛び出してしまうことがあり、これを防止するために従来から様々な試みがなされている。例えば、図１１に示すように、左右の内側板にＵ状穴を穿孔しかつ側板にこのＵ状穴に対応するＵ状ミシン線とこの両末端を結ぶ屈曲線とによって巻き取り支持用の突片を切り抜き屈曲自在に形成した考案が開示されている（例えば、特許文献１参照。）。また、図１２に示すように、左右の内側板に、縦の折れ線を介して半円状の係止片をそれぞれ設けた考案が開示されている（例えば、特許文献２参照。）。
特開平１０−２６８８１７号公報 特開平１０−２６８８１７号公報 Conventionally, this type of packaging web is stored in a paperboard carton in a state of being wound around a paper tube. In use, a desired length is drawn from the carton and then the metal made on the carton is attached. It is designed to be used after cutting with a saw blade. By the way, when pulling out this packaging web, the paper tube may sometimes jump out due to its momentum or resistance due to close contact between the wrap films, and various attempts have been made to prevent this. For example, as shown in FIG. 11, a U-shaped hole is formed in the left and right inner plates, and a U-shaped sewing machine wire corresponding to the U-shaped hole is formed in the side plate and a bending support line connecting both ends thereof. A device in which a piece is cut out and bent is disclosed (for example, see Patent Document 1). Further, as shown in FIG. 12, a device has been disclosed in which left and right inner plates are each provided with a semicircular locking piece via a vertical broken line (see, for example, Patent Document 2).

図１は本発明に係る包装用ウェブ収納カートンの具体例を示す斜視図であり、本発明の包装用ウェブ収納カートンＡは、カートン本体１とカートン本体１に被せる蓋体２とからなり、本体前板５、本体底板４、本体後板３、そして、側部が本体側板８、本体内側板７、本体糊代片９からなるカートン本体１の中に紙管Ｗに巻かれた包装用ウェブが収納され、そして、本体後板３に蓋体頂板１１を連設することにより、蓋体頂板１１、蓋体前板１２、蓋体側板１３からなる蓋体２を連結している。また、本体内側板７には、切れ線で一部を切り抜き、折れ線で内側に屈曲できるように構成された内係止片が形成され、本体側板８には、本体内側板７に設けた内係止片と対応する位置に、切れ線で一部を切り抜き、折れ線で内側に屈曲できるように構成された外係止片が形成され、内係止片と外係止片を重ねて内側に屈曲して紙管Ｗの内側に位置するように係止部Ｚを設けたことを特徴とするものである。   FIG. 1 is a perspective view showing a specific example of a packaging web storage carton according to the present invention. A packaging web storage carton A according to the present invention comprises a carton body 1 and a lid 2 that covers the carton body 1. A packaging web wound around a paper tube W in a carton body 1 consisting of a front plate 5, a main body bottom plate 4, a main body rear plate 3, and side portions of a main body side plate 8, a main body inner plate 7, and a main body glue piece 9. The lid body 2 is composed of the lid body top plate 11, the lid body front plate 12, and the lid body side plate 13 by connecting the lid body top plate 11 to the main body rear plate 3. Further, the main body inner plate 7 is formed with an inner locking piece configured to be cut out partly by a cut line and bent inward by a broken line, and the main body side plate 8 is provided with an inner plate provided on the main body inner plate 7. An outer locking piece is formed at a position corresponding to the locking piece so that a part of the outer locking piece is cut out by a broken line and bent inward by a broken line, and the inner locking piece and the outer locking piece are overlapped on the inner side. The locking portion Z is provided so as to be bent and located inside the paper tube W.

図２は本発明の包装用ウェブ収納カートンＡを組み立てる前のブランクの展開図であり、ブランク１０では、Ｎ−Ｎ線の上側がカートン本体１で、下側が蓋体２となる構成である。カートン本体１の構成部分は、本体後板３、本体底板４、本体前板５、前板補強板６が順次折れ線ａ、ｂ、ｃを介して連設され、本体後板３の両側には側板の本体内側板７、７が折れ線ｄ、ｄを介して連設され、本体底板４の両側には本体側板８、８が折れ線ｅ、ｅを介して連設され、また、本体前板５の両側には本体接着片９、９がそれぞれ折れ線ｆ、ｆを介して連設されている。   FIG. 2 is a development view of the blank before assembling the packaging web storage carton A of the present invention. In the blank 10, the upper side of the NN line is the carton body 1 and the lower side is the lid 2. The carton body 1 includes a main body rear plate 3, a main body bottom plate 4, a main body front plate 5, and a front plate reinforcing plate 6, which are successively connected via folding lines a, b and c. The main body inner plates 7 and 7 of the side plate are connected via the folding lines d and d, the main body side plates 8 and 8 are connected to both sides of the main body bottom plate 4 via the folding lines e and e, and the main body front plate 5 Main body adhesive pieces 9, 9 are connected to each other via broken lines f, f, respectively.

そして、各本体内側板７には、折れ線ｘ１で内側に屈曲でき、切れ線ｘ２で切り抜くことができるように構成された内係止片Ｘが形成され、各本体側板８には、本体内側板７に設けた内係止片Ｘと対応する位置に折れ線ｙ１と切れ線ｙ２で内側に内係止片Ｘと重ねて屈曲できるように構成された外係止片Ｙが形成されている。内係止片Ｘと外係止片Ｙは、重ねて内側に屈曲して係止部Ｚを形成できるように、概ね同形としている。実際には、包装用ウェブ収納カートンＡを組み立てた時に、本体側板８と本体内側板７に多少のずれがあった場合でも、内係止片Ｘと外係止片Ｙを重ねて内側に屈曲して係止部Ｚを形成しやすいように、外係止片Ｙの面積を内係止片Ｘの面積より小さくすることが好ましい。   Each main body inner plate 7 is formed with an inner locking piece X configured to be bent inward at a broken line x1 and cut out at a cut line x2, and each main body side plate 8 has a main body inner plate. An outer locking piece Y is formed at a position corresponding to the inner locking piece X provided in 7 so that it can be bent overlapping with the inner locking piece X on the inner side by a broken line y1 and a broken line y2. The inner locking piece X and the outer locking piece Y have substantially the same shape so that the locking portion Z can be formed by overlapping and bending inward. Actually, even when the main body side plate 8 and the main body inner plate 7 are slightly misaligned when the packaging web storage carton A is assembled, the inner locking piece X and the outer locking piece Y are overlapped and bent inward. Thus, the area of the outer locking piece Y is preferably smaller than the area of the inner locking piece X so that the locking portion Z can be easily formed.

一方、蓋体２の構成部分は、本体後板３に蓋体頂板１１が折れ線ｇを介して連設され、さらに、この蓋体頂板１１に蓋体前板１２が折れ線ｈを介して連設され、蓋体頂板１１の両側には蓋体側板１３、１３が折れ線ｉ、ｉを介して連設され、また、蓋体前板１２の両側には蓋接着片１４、１４がそれぞれ折れ線ｊ、ｊを介して連設されている。また、蓋体前板１２には、使用時に切り離して鋸刃１５を露出させるための切除部１２ａが、破断線ｋで区画され、カートンの組み立て時においてその切除部１２ａは本体前板５に形成した複数の接着ポイント１６で接着するようになっている。   On the other hand, as for the constituent parts of the lid body 2, the lid body top plate 11 is connected to the main body rear plate 3 via the broken line g, and further, the lid body front plate 12 is connected to the lid body top plate 11 via the broken line h. The lid body side plates 13 and 13 are connected to both sides of the lid body top plate 11 via the polygonal lines i and i, and the lid adhesive pieces 14 and 14 are respectively arranged on both sides of the lid body front plate 12 to the polygonal line j, j. Further, the lid front plate 12 has a cut portion 12a that is cut off at the time of use to expose the saw blade 15 by a break line k, and the cut portion 12a is formed in the main body front plate 5 when the carton is assembled. The plurality of bonding points 16 are bonded.

上記の構成からなる板紙製のブランク１０を組み立てて包装用ウェブ収納カートンＡを形成する。すなわち、ブランク１０の必要箇所に糊付けして折れ線により折り曲げて折り畳まれた状態にし、つぎの内容物の充填包装の工程で、折り畳まれた包装用ウェブ収納カートンＡを起こして組み立てて、ラップフィルムが巻かれた紙管Ｗをカートン本体１の中に収納する。この工程において、本体内側板７に形成する内係止片Ｘと本体側板８に形成する外係止片Ｙを重ねて内側に折り曲げて、図３に示すように、包装用ウェブ収納カートンＡ内に収納されている紙管Ｗの内側に係止部Ｚを形成する。この作業は、充填時にピンなどの治具により紙管Ｗの内部に折り込むことができる。また、この係止部Ｚの形成は、紙管Ｗに巻かれたラップフィルム等が収納された商品を購入した消費者が、使用する時に容易に行うこともできる。このように係止部Ｚが紙管Ｗの内側に向かって立ち上がった状態にすることにより、カートン上方への引っ張りに対して、紙管Ｗが飛び出さないように保持している。   A paperboard blank 10 having the above structure is assembled to form a packaging web storage carton A. In other words, the blank 10 is glued to a necessary portion and folded by a fold line so as to be folded, and in the next filling and packaging process of the contents, the folded packaging web storage carton A is assembled and assembled. The rolled paper tube W is stored in the carton body 1. In this step, the inner locking piece X formed on the main body inner plate 7 and the outer locking piece Y formed on the main body side plate 8 are overlapped and bent inward, as shown in FIG. The locking portion Z is formed inside the paper tube W stored in the paper. This operation can be folded into the paper tube W by a jig such as a pin during filling. Further, the formation of the locking portion Z can be easily performed by a consumer who has purchased a product in which a wrap film or the like wound around the paper tube W is used. In this way, the engaging portion Z is raised toward the inside of the paper tube W, so that the paper tube W is held so as not to jump out when pulled upward of the carton.

収納するラップフィルムは、例えば塩化ビニリデン系、塩化ビニール系、ポリエチレン系等の合成樹脂フィルムである。そして、使用に際しては、蓋体前板１２の切除部１２ａを破断線ｋに沿って除去した後、図１に示すように蓋体２を開け、中のラップフィルムの端縁を摘んで所望の長さだけ引き出してから鋸刃１５で切断する。   The wrap film to be stored is, for example, a synthetic resin film such as vinylidene chloride, vinyl chloride, or polyethylene. In use, after removing the cut portion 12a of the lid front plate 12 along the breaking line k, the lid 2 is opened as shown in FIG. The length is pulled out and then cut with the saw blade 15.

また、内係止片Ｘおよび外係止片Ｙの一辺を直線の折り曲げ可能な折れ線ｘ１、ｙ１とし、他の部分を切り抜き可能な切れ線ｘ２、ｙ２としているが、この切れ線ｘ２、ｙ２は、切れ刃による切れ目、ミシン目、半切れ等とする。この内係止片Ｘ、外係止片Ｙは、本体側板８、本体内側板７の略中央部にそれぞれ設け、その位置は、内係止片Ｘおよび外係止片Ｙをラップフィルム等を巻いた紙管Ｗの内側に折り曲げることができるように、ラップフィルム等を巻いた紙管Ｗを包装用ウェブ収納カートンＡに収納した初期の段階で、図４に示すような紙管Ｗの内側の領域に対応する領域内Ｒとする。そして、紙管Ｗが上方に移動する距離を制限するために、折れ線ｘ１、ｙ１の下端ｍを領域内Ｒの下半円形線ｒ（太線部分）に近づけることが好ましい。   In addition, one side of the inner locking piece X and the outer locking piece Y is a foldable fold line x1, y1 and the other part is a cuttable line x2, y2, which can be cut out. , Cuts by cutting edges, perforations, half cuts, etc. The inner locking piece X and the outer locking piece Y are provided at substantially the center portions of the main body side plate 8 and the main body inner plate 7, respectively, and the positions of the inner locking piece X and the outer locking piece Y are the wrap film and the like. At the initial stage of storing the paper tube W wrapped with a wrap film or the like in the packaging web storage carton A so that it can be folded inside the rolled paper tube W, the inside of the paper tube W as shown in FIG. An in-region R corresponding to the region of. In order to limit the distance that the paper tube W moves upward, it is preferable to bring the lower end m of the polygonal lines x1 and y1 closer to the lower semicircular line r (thick line portion) in the region R.

また、折れ線ｘ１、ｙ１の角度αを、図５に示すように、折れ線ｘ１、ｙ１の上端ｌが本体前板側に下端ｍが本体後板側に傾斜させて、本体底板１３に垂直な垂直線との角度を０〜５０度の範囲とすることが好ましい。この範囲内にすることにより、屈曲した内係止片Ｘ、外係止片Ｙが元に戻りにくく、紙管Ｗの飛び出しを効果的に防ぐことができ、強度を保つことができる。角度αが５０度を越えると、内側に折り曲げた内係止片Ｘおよび外係止片Ｙが、さらに倒れ込み易くなり、あるいは元へ戻り易くなり、紙管Ｗのを飛び出し防止の効果が極端に低下する。特に、この角度αを４５度に近くすることが好ましく、その理由としては、図６に示すように、ラップフィルム等を巻いた紙管Ｗは、ラップフィルム等が引き出される時、ｐ１の力で前上方向に引っ張られると共に、本体前板５に接しながら図における時計周りに回転して行くため、本体前板５に沿って上昇するｐ２の力が発生し、そして、ｐ１とｐ２を合成したＰという力が紙管Ｗを略４５度の斜め上方向へ引き上げようとする。従って、この方向に対して飛び出すことを防止することが有効になり、折れ線ｘ１、ｙ１の角度を４５度に近づけることが好ましい。   Further, as shown in FIG. 5, the angle α of the polygonal lines x1 and y1 is perpendicular to the main body bottom plate 13 by inclining the upper end l of the bent lines x1 and y1 toward the front plate of the main body and the lower end m toward the rear plate of the main body. The angle with the line is preferably in the range of 0 to 50 degrees. By setting it within this range, the bent inner locking piece X and outer locking piece Y are unlikely to return to the original, and the paper tube W can be effectively prevented from jumping out and the strength can be maintained. When the angle α exceeds 50 degrees, the inner locking piece X and the outer locking piece Y that are bent inward are more likely to fall or return to the original, and the effect of preventing the paper tube W from popping out becomes extremely large. descend. In particular, it is preferable to make this angle α close to 45 degrees because, as shown in FIG. 6, the paper tube W wrapped with a wrap film or the like has a force of p1 when the wrap film or the like is pulled out. While pulling forward and rotating in the clockwise direction in the figure while contacting the main body front plate 5, a force of p2 rising along the main body front plate 5 is generated, and p1 and p2 are synthesized. The force P attempts to pull up the paper tube W obliquely upward by about 45 degrees. Therefore, it is effective to prevent the jumping in this direction, and it is preferable to make the angles of the polygonal lines x1 and y1 close to 45 degrees.

内係止片Ｘおよび外係止片Ｙの形状は、図７−ａ、ｂ、ｃに示すように、半円形、Ｕ字形、三角形、四角形、台形等とすることができ、角部が引っかからないように、角丸とすることが好ましい。また、図７−ｄに示すように、折れ線ｘ、ｙの下端ｍから折れ線ｘ、ｙに直角に直線部分を有する形状とすることが好ましく、この形状にすることによって、図８に示すように、紙管Ｗを内側から直線部分で支持することができ、紙管Ｗの飛び出しを防ぐ効果が高くなる。また、ころがり抵抗を少なくするため、図７−ｅに示すように、直線部分を波形として複数の点接触とする形状としてもよい。   The shapes of the inner locking piece X and the outer locking piece Y can be semicircular, U-shaped, triangular, quadrangular, trapezoidal, etc., as shown in FIGS. It is preferable to use rounded corners. Further, as shown in FIG. 7D, it is preferable to have a shape having a straight line portion perpendicular to the fold lines x and y from the lower end m of the fold lines x and y, and by using this shape, as shown in FIG. The paper tube W can be supported by the linear portion from the inside, and the effect of preventing the paper tube W from jumping out becomes high. Moreover, in order to reduce rolling resistance, as shown to FIG.7-e, it is good also as a shape which makes a linear part a waveform and makes a some point contact.

また、係止部Ｚの折り込む角度βは、略９０度とすることが好ましいが、実際には、図９の概略上面図に示すように、折り込まれた係止部Ｚは、紙管Ｗの回転に引っ張られて倒されやすいので、予め、９０度より小さく４５〜８０度の範囲としてもよい。   In addition, the folding angle β of the locking portion Z is preferably approximately 90 degrees, but actually, as shown in the schematic top view of FIG. Since it is easily pulled down by rotation, it may be in a range of 45 to 80 degrees smaller than 90 degrees in advance.

また、本体内側板７に設けた内係止片Ｘと本体側板８に設けた外係止片Ｙは、重ねて内側に屈曲して係止部Ｚを形成できるように、概ね同形としているが、内係止片Ｘの切れ線ｘ２の一部に凹部を設け、内係止片Ｘを内側に屈曲させた後の抜き穴の一部に凸状部ｘ３を設けた形状とすることもできる。このように、内係止片Ｘを内側に屈曲させた後の抜き穴の一部に凸状部ｘ３が設けられることにより、重ねて屈曲した外係止片Ｙが元に戻ることを防いだ形状となっている。従って、図１０に示すように、屈曲させた係止部Ｚが戻りにくい形になる。この凸状部ｘ３は、折れ線ｘ１に近い位置に設けることが効果的であり、特に、折れ線ｘ１の下端に近い位置に設けることが効果的である。   In addition, the inner locking piece X provided on the main body inner plate 7 and the outer locking piece Y provided on the main body side plate 8 have substantially the same shape so that they can be overlapped and bent inward to form the locking portion Z. Further, it is also possible to form a recess in a part of the cut line x2 of the inner locking piece X and to provide a convex part x3 in a part of the punched hole after the inner locking piece X is bent inward. . As described above, the convex portion x3 is provided in a part of the punched hole after the inner locking piece X is bent inward, thereby preventing the outer locking piece Y bent and overlapped from returning. It has a shape. Therefore, as shown in FIG. 10, the bent locking portion Z is difficult to return. It is effective to provide the convex portion x3 at a position near the polygonal line x1, and it is particularly effective to provide it at a position near the lower end of the polygonal line x1.

また、上記の例では折れ線ｘ１、ｙ１の斜め下方向（前板１２側）に内係止片Ｘ、外係止片Ｙを形成したが、折れ線ｘ１、ｙ１の斜め上方向（後板１４側）に内係止片Ｘ、外係止片Ｙを形成して、係止部Ｚを屈曲させる方向を上記の例と逆にした形態にしてもよいが、紙管Ｗの回転方向（図４で時計周り）を考慮すると、回転方向に逆らう方向となる折れ線ｘ１、ｙ１の斜め下方向（前板１２側）に内係止片Ｘ、外係止片Ｙを形成した形状の方が、折れ線ｘ１、ｙ１の斜め上方向（後板１４側）に内係止片Ｘ、外係止片Ｙを形成した形状に比較して、折り曲げた状態から元へ戻りにくく好ましい。   In the above example, the inner locking piece X and the outer locking piece Y are formed in the diagonally downward direction (front plate 12 side) of the polygonal lines x1 and y1, but the diagonally upward direction (rear plate 14 side) of the polygonal lines x1 and y1. ), The inner locking piece X and the outer locking piece Y may be formed, and the direction in which the locking portion Z is bent may be reversed from the above example. (Clockwise), the shape in which the inner locking piece X and the outer locking piece Y are formed obliquely downward (front plate 12 side) with respect to the broken lines x1 and y1 in the direction opposite to the rotation direction is the broken line. Compared to the shape in which the inner locking piece X and the outer locking piece Y are formed in the diagonally upward direction of x1 and y1 (on the rear plate 14 side), it is preferable that the bent state is difficult to return.
