図1はラップフィルム収納箱1の概略を示す斜視図であり、図2は図1のラップフィルム収納箱1の表面側の展開図である。図3は蓋部を開けた状態のラップフィルム収納箱1の斜視図である。   FIG. 1 is a perspective view schematically showing the wrap film storage box 1, and FIG. 2 is a development view of the front side of the wrap film storage box 1 of FIG. FIG. 3 is a perspective view of the wrap film storage box 1 with the lid portion opened.

図1及び図2に示すようにラップフィルム収納箱1(箱本体)は、全体が直方体形状を有し、例えば掩蓋片10、蓋板11、脇掩蓋片12等からなる蓋部13と、前板14、底板15、後板16、脇板17、折返し片18等からなる収納部19と、開封片20とを有している。なお、折返し片18は、前板14の裏面(内面)側に折り返されるものであり、外観には現れない。   As shown in FIGS. 1 and 2, the wrap film storage box 1 (box body) has a rectangular parallelepiped shape as a whole. For example, the lid 13 includes a lid piece 10, a lid plate 11, a side lid piece 12, and the like, A storage portion 19 including a plate 14, a bottom plate 15, a rear plate 16, a side plate 17, a folded piece 18, and the like, and an opening piece 20 are provided. Note that the folded piece 18 is folded back to the back surface (inner surface) side of the front plate 14 and does not appear on the appearance.

図3に示すように収納部19は、上面開口19aを有する直方体状に形成され、透明のラップフィルムFが円筒状の芯体に巻かれたフィルム巻回体Rを上面開口部19aから収納できる。   As shown in FIG. 3, the storage part 19 is formed in a rectangular parallelepiped shape having an upper surface opening 19a, and a film roll R in which a transparent wrap film F is wound around a cylindrical core body can be stored from the upper surface opening part 19a. .

図1に示すように蓋部13の蓋板11は、後板16の上端縁から前方に延びて収納部19の上面開口19aを覆っている。掩蓋片10は、蓋板11の前端縁から前板14側に延びて前板14の前面を覆っている。   As shown in FIG. 1, the lid plate 11 of the lid portion 13 extends forward from the upper end edge of the rear plate 16 and covers the upper surface opening 19 a of the storage portion 19. The lid cover piece 10 extends from the front edge of the cover plate 11 toward the front plate 14 and covers the front surface of the front plate 14.

開封片20は、収納部19の前板14の前面下部に位置し、ラップフィルム収納箱1の長手方向に沿って帯状に形成されている。開封片20は、掩蓋片10の先端縁に切り取り線21を介して接続されている。開封前、開封片20の裏面側は、図2に示す前板14の複数の接着部22に接着している。この開封片20によって蓋部13が封止されており、図4に示すように開封片20を切り取り線21に沿って端から切り取ることによって蓋部13を開封することができる。   The opening piece 20 is located in the lower part of the front surface of the front plate 14 of the storage unit 19 and is formed in a strip shape along the longitudinal direction of the wrap film storage box 1. The unsealing piece 20 is connected to the tip edge of the lid cover piece 10 via a cut line 21. Before opening, the back side of the opening piece 20 is bonded to the plurality of bonding portions 22 of the front plate 14 shown in FIG. The lid portion 13 is sealed by the opening piece 20, and the lid portion 13 can be opened by cutting the opening piece 20 from the end along the cut line 21 as shown in FIG.

図5に示すように複数の接着部22は、例えば同じ円形状で同じ面積(同じ大きさ)を有し、前板14の長手方向に沿って前板14の両端部間に亘り一列に並べられている。前板14の端部領域Sの接着部22Aは、前板14の中央領域Cの接着部22Bよりも、互いの間隔が狭くなるように配置されている。具体的には、例えば接着部22B同士の間隔L1が30〜80mm程度であるのに対し、接着部22A同士の間隔L2は、好ましくは5〜25mm、より好ましくは10〜20mm程度に設定されている。なお、このときの「間隔」とは、接着部の端から隣の接着部の端までの最短距離を意味する。本実施の形態において中央領域Cは、例えば前板14を長手方向に三等分したときの中央の領域であり、端部領域Sは、その両側の領域である。   As shown in FIG. 5, the plurality of bonding portions 22 have, for example, the same circular shape and the same area (the same size), and are arranged in a line between both end portions of the front plate 14 along the longitudinal direction of the front plate 14. It has been. The bonding portions 22A in the end region S of the front plate 14 are arranged so that the distance between them is narrower than the bonding portions 22B in the central region C of the front plate 14. Specifically, for example, the interval L1 between the bonding portions 22B is about 30 to 80 mm, while the interval L2 between the bonding portions 22A is preferably set to about 5 to 25 mm, more preferably about 10 to 20 mm. Yes. The “interval” at this time means the shortest distance from the end of the bonded portion to the end of the adjacent bonded portion. In the present embodiment, the central region C is, for example, a central region when the front plate 14 is divided into three equal parts in the longitudinal direction, and the end region S is a region on both sides thereof.

図1及び図2に示すように開封片20には、前板14の各接着部22に対応する位置に、半円切れ目25が形成されている。これにより、仮に開封片20側で想定外の層間剥離が生じた場合に半円切れ目25で当該剥離を遮断することができる。なお、この半円切れ目25はあってもなくてもよい。   As shown in FIGS. 1 and 2, the opening piece 20 is formed with a semicircular cut 25 at a position corresponding to each adhesive portion 22 of the front plate 14. Thereby, when an unexpected delamination occurs on the side of the opening piece 20, the separation can be blocked by the semicircle cut 25. The semicircle cut 25 may or may not be present.

掩蓋片10の先端部の裏側には、図3及び図4に示すように収納部19のフィルム巻回体Rから引き出されたラップフィルムFを切断する切断部としての鋸刃30が設けられている。鋸刃30は、ラップフィルム収納箱1(掩蓋片10)の長手方向の両側端に亘って形成されている。鋸刃30は、開封片20を切り取った時に、掩蓋片10の先端縁から下方に突出する位置に形成されている。なお、この鋸刃30などの切断部の材質は、金属、プラスチック、バルカナイズドファイバー等であり、切断部の形状は、直線状、V状、アーチ状、M字状等従来公知のものであれば特に制限はない。   As shown in FIGS. 3 and 4, a saw blade 30 as a cutting portion for cutting the wrap film F drawn from the film winding body R of the storage portion 19 is provided on the back side of the distal end portion of the lid piece 10. Yes. The saw blade 30 is formed across both longitudinal ends of the wrap film storage box 1 (the lid piece 10). The saw blade 30 is formed at a position protruding downward from the tip edge of the lid cover piece 10 when the opening piece 20 is cut off. The material of the cutting portion such as the saw blade 30 is metal, plastic, vulcanized fiber, etc., and the shape of the cutting portion is a conventionally known one such as a straight shape, a V shape, an arch shape, or an M shape. There is no particular limitation.

図2及び図3に示すように前板14の表面には、切断後に残るフィルム巻回体RのラップフィルムFを、巻き戻らないように仮留めする仮留め部40が形成されている。仮留め部40は、例えばUV硬化のニスにより形成され、粘着性を有している。仮留め部40は、ラップフィルム収納箱1の長手方向に沿って形成されている。   As shown in FIGS. 2 and 3, a temporary fastening portion 40 is formed on the front plate 14 for temporarily fastening the wrap film F of the wound film R remaining after cutting so as not to be rewound. The temporary fixing portion 40 is formed of, for example, a UV curable varnish and has adhesiveness. The temporary fastening portion 40 is formed along the longitudinal direction of the wrap film storage box 1.

ラップフィルム収納箱1を構成する原紙としては、例えば、ボール紙、コートボール紙、段ボール等が挙げられるが、これらに限定されず、当業界で公知の紙類を適宜選択して用いることができる。原紙は、これらの素材に、エンボス加工、印刷加工、ポリエチレン等を用いたラミネート加工が施されたものであっても構わない。   Examples of the base paper constituting the wrap film storage box 1 include, but are not limited to, cardboard, coated cardboard, cardboard, and the like, and papers known in the art can be appropriately selected and used. . The base paper may be one obtained by embossing, printing, or laminating using polyethylene or the like on these materials.

本実施の形態によれば、開封片20の前板14の端部領域Sの接着部22Aが、前板14の中央領域Cの接着部22Bよりも、互いの間隔が狭く形成されている。ラップフィルム収納箱1の移送中の衝突、および販売中の落下による衝撃は、開封片の中央部より両端部に大きくかかることから、前板14に対する開封片20の端部領域S全体の接着力を大きくすることで開封片20が端部から剥がれることを防止できる。よって、開封片20の封止性を十分に確保できる。また、端部領域Sの接着部22Aが、中央領域Cの接着部22Bと同じ面積であるので、開封片20を端から一方向(図中の開封方向X)に切り取り各接着部22A、22Bから順に剥がす際に、開封片20が各接着部22A、22Bの接着力から受ける負荷が一定になる。この結果、一部に接着力の強い接着部がある場合のように開封片20が途中でちぎれたり破れたりすることなく開封片20を適切に切り取ることができる。よって、開封片20の開封性を十分に確保できる。   According to the present embodiment, the bonding portion 22 </ b> A in the end region S of the front plate 14 of the opening piece 20 is formed to be narrower than the bonding portion 22 </ b> B in the central region C of the front plate 14. The impact during transfer of the wrap film storage box 1 and the impact caused by the drop during sales are applied to both ends from the center of the unsealed piece, and therefore the adhesive strength of the entire end region S of the unsealed piece 20 to the front plate 14 Can be prevented from peeling off from the end. Therefore, the sealing property of the opening piece 20 can be sufficiently ensured. Further, since the adhesive portion 22A of the end region S has the same area as the adhesive portion 22B of the central region C, the opening piece 20 is cut from the end in one direction (opening direction X in the drawing), and the respective adhesive portions 22A, 22B. , The load that the unsealed piece 20 receives from the adhesive force of the adhesive portions 22A and 22B becomes constant. As a result, the opening piece 20 can be appropriately cut off without the tearing piece 20 being torn or torn in the middle as in the case where there is an adhesive portion having a strong adhesive force in part. Therefore, the opening property of the opening piece 20 can be sufficiently ensured.

以上の実施の形態において、端部領域Sにおける接着部22Aの総接着力が、中央領域Cにおける接着部22Bの総接着力より大きく、なおかつ、開封片20を一方向に切り取る際に開封片20が接着部22A、22Bの接着力から受ける負荷が同程度であれば、接着部22A、接着部22Bは、他の配列、大きさであってもよい。また別の観点から、以上の実施の形態において、左右2カ所の各端部領域Sにおける接着部22Aの総面積D1が、中央領域Cにおける接着部22Bの総面積D2よりも大きく、各接着部22Aの面積E1が、各接着部22Bの面積E2と同じかそれより小さくてもよい。なお、左右2カ所の端部領域Sは、総面積D1が必ずしも一致する必要はなく、また各接着部22Aの面積E1も必ずしも同じである必要はない。   In the above embodiment, the total adhesive force of the adhesive portion 22A in the end region S is greater than the total adhesive force of the adhesive portion 22B in the central region C, and when the open piece 20 is cut in one direction, the open piece 20 If the loads received from the adhesive force of the adhesive portions 22A and 22B are approximately the same, the adhesive portions 22A and the adhesive portions 22B may have other arrangements and sizes. From another point of view, in the above embodiment, the total area D1 of the adhesive portion 22A in each of the left and right end regions S is larger than the total area D2 of the adhesive portion 22B in the central region C. The area E1 of 22A may be the same as or smaller than the area E2 of each bonding portion 22B. The two end regions S on the left and right sides do not necessarily have the same total area D1, and the area E1 of each bonding portion 22A does not necessarily have to be the same.

例えば図6に示すように端部領域Sの接着部22Aが長手方向に沿って複数列、例えば2列に並べられていてもよい。この場合、例えば長手方向に隣り合う接着部22A同士の間隔L2は、接着部22B同士の間隔L1よりも狭く、各接着部22Aは、接着部22Bよりも面積が小さくてもよい。かかる場合、端部領域Sの全体の接着力が中央領域Cの全体の接着力よりも大きくなり、開封片20の封止性を確保できる。また、開封片20を一方向に切り取る際に開封片20が各接着部22A、22Bの接着力から受ける負荷が同程度に維持されるので、開封片20の開封性を確保できる。   For example, as shown in FIG. 6, the adhesive portions 22 </ b> A in the end region S may be arranged in a plurality of rows, for example, two rows along the longitudinal direction. In this case, for example, the interval L2 between the adhering portions 22A adjacent in the longitudinal direction is narrower than the interval L1 between the adhering portions 22B, and the area of each adhering portion 22A may be smaller than that of the adhering portions 22B. In such a case, the overall adhesive force of the end region S is greater than the overall adhesive force of the central region C, and the sealing performance of the opening piece 20 can be ensured. Moreover, since the load which the opening piece 20 receives from the adhesive force of each adhesion part 22A, 22B when cutting the opening piece 20 to one direction is maintained about the same level, the opening property of the opening piece 20 is securable.

また、上記接着部22Aを複数列に配置する例において、図7に示すように上下に隣接する列の接着部22Aが互い違いになるように配置されてもよい。この場合、長手方向に隣り合う接着部22A同士の間隔L2は、列の異なる最も近い接着部22A同士の間の距離となる。   Moreover, in the example which arrange | positions the said adhesion part 22A in several rows, as shown in FIG. 7, you may arrange | position so that the adhesion part 22A of the row | line | column adjacent up and down may become alternate. In this case, the distance L2 between the adhesive portions 22A adjacent in the longitudinal direction is the distance between the closest adhesive portions 22A in different rows.

また、上記接着部22Aを複数列に配置する例において、図8に示すように中央領域Cの接着部22Bが、上記接着部22Aと同様に複数列、例えば2列に並べられていてもよい。この場合も、接着部22A同士の間隔L2は、長手方向に隣り合う接着部22B同士の間隔L1よりも狭くなっている。   Further, in the example in which the bonding portions 22A are arranged in a plurality of rows, the bonding portions 22B in the central region C may be arranged in a plurality of rows, for example, two rows, similarly to the bonding portion 22A, as shown in FIG. . Also in this case, the interval L2 between the bonding portions 22A is narrower than the interval L1 between the bonding portions 22B adjacent in the longitudinal direction.

なお、以上の実施の形態では、端部領域S及び中央領域Cが前板14を長手方向に三等分したものであったが、必ずしもその必要はない。図9に示すように前板14の端を含む所定長さの端部領域Sの接着部22A同士の間隔L2が、前板14の中央を含む所定長さの中央領域Cの接着部22B同士の間隔L1よりも狭く、接着部22Aの面積が接着部22Bの面積と同じか小さくてもよい。ただし、端部領域Sは、前板14の1/6以上の長さを有するのが好ましい。   In the above embodiment, the end region S and the central region C are obtained by dividing the front plate 14 into three equal parts in the longitudinal direction, but this is not always necessary. As shown in FIG. 9, the distance L2 between the bonding portions 22A of the end region S having a predetermined length including the end of the front plate 14 is equal to the bonding portions 22B of the central region C having a predetermined length including the center of the front plate 14. The area of the bonding part 22A may be the same as or smaller than the area of the bonding part 22B. However, the end region S preferably has a length of 1/6 or more of the front plate 14.

以上の実施の形態における接着部22の個数は特に限定するものではないが、ラップフィルム収納箱1の長手方向のサイズに合わせ、4〜16個の範囲にあることが好ましい。また、各接着部22の面積は、19.6mm2以下であることが好ましく、より好ましくは4.5〜16.0mm2の範囲である。このような範囲にあれば、開封性と封止性のバランスが取りやすい。 Although the number of the adhesion parts 22 in the above embodiment is not specifically limited, According to the size of the longitudinal direction of the wrap film storage box 1, it is preferable to exist in the range of 4-16 pieces. Moreover, it is preferable that the area of each adhesion part 22 is 19.6 mm < 2 > or less, More preferably, it is the range of 4.5-16.0 mm < 2 >. If it is in such a range, it will be easy to balance openability and sealing performance.

また、接着部22の形態は、特に限定するものではないが、例えば、円形或いは楕円形を有し、その周縁部には、前板14の厚み方向に非貫通の半切り込み線を形成し、接着部22の周囲には接着剤との剥離性が良好なニスが塗布され、そのニス塗布面に対し接着剤が仮留め程度の接着力しか示さないようにしてもよい。かかる場合、開封片20を開封方向に引っ張って、前板14の非貫通の半切り込み線で囲まれた接着部22を層間剥離させることにより、開封片20を切り取ることができる。   Further, the form of the bonding portion 22 is not particularly limited. For example, the bonding portion 22 has a circular shape or an oval shape, and a non-penetrating half-cut line is formed on the peripheral edge portion in the thickness direction of the front plate 14, A varnish having good releasability from the adhesive may be applied around the adhesive portion 22 so that the adhesive exhibits only an adhesive strength that is only temporarily fixed to the varnish application surface. In this case, the opening piece 20 can be cut off by pulling the opening piece 20 in the opening direction to delaminate the adhesive portion 22 surrounded by the non-penetrating half-cut line of the front plate 14.

また、接着部22は、その周縁部に切り込みが無く平坦であってもよい。接着部22の周辺には接着剤との剥離性が良好なニスが塗布され、そのニス塗布面に対し接着剤が仮留め程度の接着力しか示さないようにしてもよい。かかる場合、開封片20を切り取る際に、開封片20側を層間剥離させ、開封片20を切り取ることができる。   Further, the bonding portion 22 may be flat without a cut at the peripheral edge portion. A varnish having good releasability from the adhesive may be applied to the periphery of the adhesive portion 22 so that the adhesive exhibits only an adhesive strength of a temporary fixing level on the varnish application surface. In this case, when the opening piece 20 is cut off, the opening piece 20 side can be delaminated and the opening piece 20 can be cut off.

以上の実施の形態で記載した開封片20の切り取り線21は、図2に示すように開封片20の開封開始端から開封終了端にわたり断続的に形成された複数の切り込み50から構成されていてもよい。例えば切り込み50は、開封方向Xに略垂直の縦向きの切り込み線50aと、開封方向Xに沿った横向きの切り込み線50bを有している。例えば各切り込み50は、一対の縦向きの切り込み線50aと横向きの切り込み線50bが交差して略T字或いは略J字形状を有している。横向きの切り込み線50bは、例えば縦向きの切り込み線50aの中央付近から開封方向X側に延びている。   The tear line 21 of the opening piece 20 described in the above embodiment is composed of a plurality of cuts 50 formed intermittently from the opening start end to the opening end end of the opening piece 20 as shown in FIG. Also good. For example, the cut 50 has a vertical cut line 50 a substantially perpendicular to the opening direction X and a horizontal cut line 50 b along the opening direction X. For example, each of the cuts 50 has a substantially T-shape or a substantially J-shape in which a pair of vertical cut lines 50a and horizontal cut lines 50b intersect. The horizontal cut line 50b extends, for example, from the vicinity of the center of the vertical cut line 50a toward the opening direction X.

開封の際には、開封片20を開封方向Xへ引っ張ることにより、接着部22における剥離と、切り込み50相互間のつなぎ部分の破断が生じ、開封片20が前板14および掩蓋片10から離れることにより、蓋部13が開封される。また、開封片20を切り取る際に、一の横向きの切り込み線50bの端部から、次の縦向きの切り込み線50aに至る過程で、つなぎ部分の破断方向が多少上下しても、次の切り込み50の縦向きの切り込み線50aの範囲で破断を受け止めることができる。   At the time of opening, the opening piece 20 is pulled in the opening direction X to cause peeling at the bonding portion 22 and breakage of the connecting portion between the notches 50, and the opening piece 20 is separated from the front plate 14 and the lid piece 10. As a result, the lid 13 is opened. Further, when the opening piece 20 is cut, even if the breaking direction of the joint portion is slightly increased or lowered in the process from the end of one horizontal cut line 50b to the next vertical cut line 50a, the next cut Breakage can be received within a range of 50 longitudinal cut lines 50a.

両端付近の隣り合う接着部22Aの間には、相当する位置の開封片20の切り込み50bと切り込み50bの間のつなぎ部60と切り込み50の縦向きの切り込み線50aが配置されていることが好ましい。かかる場合、開封片20を開封開始端から剥がすときに、縦向きの切り込み線50aの部分で一度開封片20が折れる(曲がる)ことで、手前の接着部22Aの剥離が完了する。隣り合う接着部22Aの間に縦向きの切り込み線50aがない場合、開封片20が折れ曲がらずに同時に次の接着部22Aまで剥がれはじめ、接着部22Aの2か所分の抵抗が生じる。隣り合う接着部22Aの間につなぎ部60及び縦向きの切り込み線50aがあると、隣接する接着部22Aが、各々独立して開封されていくため、より開封を容易にすることができるため好ましい。より好ましくは、両端付近の間隔の狭い接着部22Aにおいて、接着部22Aの開封開始側の端から、開封開始側に6mm以内に、切り込み50と切り込み50の間のつなぎ部60、あるいは縦向きの切り込み線50aを少なくとも一つを配置する。ただし、この場合、接着部22上に切り込み50と切り込み50の間のつなぎ部60、あるいは縦向きの切り込み線50aが配置されないように、接着部22間の距離に合わせ、設計する必要がある。更に好ましくは、切り込み50と切り込み50の間のつなぎ部60及び縦向きの切り込み線50aが、接着部22の開封開始側の端から、開封開始側に1〜3mmの範囲にあるとよい。このような範囲にあると、開封片20を剥がす際に、接着部22の直前で一旦開封片20が折れ曲がるので、開封時の力が効果的に接着部22に作用する。この結果、容易に開封できるとともに、不必要な接着部22上での開封片20の折れ曲がりを抑制でき、開封片20のちぎれを抑制する等の効果が得られる。   Between the adjacent adhesive portions 22A in the vicinity of both ends, a connecting portion 60 between the notch 50b and the notch 50b at the corresponding position and a longitudinal notch line 50a of the notch 50 are preferably disposed. . In this case, when the opening piece 20 is peeled off from the opening start end, the opening piece 20 is once bent (bent) at the portion of the longitudinal cut line 50a, whereby the peeling of the front adhesive portion 22A is completed. When there is no longitudinal cut line 50a between the adjacent adhesive portions 22A, the unsealed piece 20 does not bend and starts to peel to the next adhesive portion 22A at the same time, and resistance of two portions of the adhesive portion 22A occurs. It is preferable that the connecting portion 60 and the longitudinal cut line 50a exist between the adjacent adhesive portions 22A because the adjacent adhesive portions 22A are opened independently, and can be opened more easily. . More preferably, in the adhesive portion 22A having a narrow interval near both ends, the connecting portion 60 between the cut 50 and the cut 50, or the longitudinal direction, is within 6 mm from the opening start side end of the adhesive portion 22A. At least one cut line 50a is arranged. However, in this case, it is necessary to design in accordance with the distance between the bonding portions 22 so that the connection portion 60 between the cuts 50 and the cut portion 50 or the vertical cut line 50a is not disposed on the bonding portion 22. More preferably, the connecting portion 60 between the cuts 50 and the cut line 50a in the vertical direction may be within a range of 1 to 3 mm from the opening start side end of the adhesive portion 22 to the opening start side. In such a range, when the opening piece 20 is peeled off, the opening piece 20 is once bent just before the bonding portion 22, so that the force at the time of opening acts on the bonding portion 22 effectively. As a result, while being able to open easily, unnecessary bending of the opening piece 20 on the bonding portion 22 can be suppressed, and effects such as suppressing tearing of the opening piece 20 can be obtained.
