Description

本発明は、ティシュペーパー、ペーパータオル、キッチンペーパー等が収納される衛生薄葉紙収納箱に関する。   The present invention relates to a sanitary thin paper storage box in which tissue paper, paper towels, kitchen paper and the like are stored.

衛生薄葉紙収納箱としては、直方体形状の紙箱の上面に環状のミシン目線が形成され、その環状ミシン目線内及びその周囲部を被覆するようにして、紙箱内面にスリットを有する樹脂製又は樹脂を含むフィルムシートを貼付した構造を採るのが一般的である。   As the sanitary thin paper storage box, a ring-shaped perforation line is formed on the top surface of a rectangular parallelepiped paper box, and includes a resin or a resin having a slit on the inner surface of the paper box so as to cover the inside of the ring perforation line and the periphery thereof. Generally, a structure in which a film sheet is attached is adopted.

使用に際しては、環状のミシン目線を切り剥がすことで、紙箱に取出し口を形成し、その取出し口内にスリットを露出させる。使用者はこのスリットを介して衛生薄葉紙を引き出して使用する。   At the time of use, an annular perforation line is cut off to form a takeout opening in the paper box, and the slit is exposed in the takeout opening. The user draws and uses the sanitary thin paper through this slit.

ところで、衛生薄葉紙収納箱は、内部のティシュペーパー等を使いきった後、廃棄するにあたって、ゴミの分別回収等の理由等により、紙箱とフィルムシートとの分別が求められることがある。   By the way, the sanitary thin paper storage box may be required to be separated into a paper box and a film sheet due to reasons such as separation and collection of dust, etc., when the tissue paper inside the sanitary thin paper storage box is used up and discarded.

このため、従来の衛生薄葉紙収納箱においては、例えば、特許文献1や特許文献2のように、フィルムシートを箱内面に貼付するために環状のミシン目線を囲むように配置される糊を間欠的に配置する糊付けパターンにしてフィルムシートを剥がし易くしている。   For this reason, in the conventional sanitary thin paper storage box, for example, as in Patent Document 1 and Patent Document 2, the adhesive disposed so as to surround the annular perforation line in order to attach the film sheet to the inner surface of the box is intermittent. It is easy to peel off the film sheet by using a gluing pattern to be disposed on.

しかし、上記の各特許文献のように糊を間欠的に配置する糊付けパターンでは、糊付け部分と非糊付け部分との接着力の差が大きく、引き剥がしの際に糊付け部分にフィルムが一部ちぎれて残り、完全に分離されないことがあった。   However, in the gluing pattern in which the glue is intermittently disposed as in each of the above patent documents, the difference in the adhesive force between the gluing part and the non-gluing part is large, and the film is partially broken at the gluing part when peeling off. In some cases, it was not completely separated.

また、上記糊付けパターンを糊の転写により付与しようとすると糊版の糊非付与部分に糊粕が溜まりやすく均一な転写を行なうことが困難であった。   In addition, when the paste pattern is applied by transfer of paste, it has been difficult to perform uniform transfer because glue cake tends to accumulate in the non-applied portion of the paste plate.

特許第4836600号Patent No. 4836600 特開2008−247446号公報JP 2008-247446 A

そこで、本発明の主たる課題は、紙箱とフィルムシートの分離性と引き剥がしの操作性に優れ、製造時に糊粕も出難い、衛生薄葉紙収納箱を提供することにある。   Therefore, the main problem of the present invention is to provide a sanitary thin paper storage box that is excellent in the separation and peeling operability of the paper box and the film sheet, and is less likely to have glue paste at the time of manufacture.

〔作用効果〕
本発明に係る衛生薄葉紙収納箱は、紙箱長手方向に延在する裂開用ミシン目線の長辺に沿って接着糊が配されており、その部分が、連続線内に、長手方向中央から短辺方向に向かって凸のV字状非接着部が間隔を開けて複数設けられているパターンとなっている。
[Function and effect]
In the sanitary thin paper storage box according to the present invention, the adhesive paste is arranged along the long side of the perforation line extending in the longitudinal direction of the paper box, and the portion is short from the center in the longitudinal direction within the continuous line. In the pattern, a plurality of V-shaped non-adhesive portions protruding in the side direction are provided at intervals.

この糊付けパターンは、紙箱からフィルムシートを引き剥がす際に、V字状非接着部に比してそれらの間の部分を引き剥がす際に強い力が必要となる。このためV字状非接着部に係る部位でフィルムシートが勢いよく剥がされる。   This gluing pattern requires a stronger force when peeling the film sheet from the paper box than when the film sheet is peeled off as compared to the V-shaped non-bonded portion. For this reason, a film sheet is peeled off vigorously in the site | part which concerns on a V-shaped non-adhesion part.

本発明の接着糊の糊付けパターンは、連続線内にV字状非接着部が位置しており、非接着部が抜き部として存在しているため、連続線が非接着部によって完全に分断されていない。よって、連続線が完全に分断されている場合、すなわち上記特許文献1、2のように接着糊が間欠的に配置されている場合には、接着糊の存在部分で過度に付勢されて次のドット部で勢いが付きすぎてフィルムシートがちぎれて紙箱側に残るが、本発明では連続線が完全に分断されていないため過度に勢いが付かずフィルムシートがちぎれて紙箱側に残るようなことがない。   In the adhesive paste gluing pattern of the present invention, the V-shaped non-adhesive portion is located in the continuous line, and the non-adhesive portion exists as a cut-out portion. Therefore, the continuous line is completely divided by the non-adhesive portion. Not. Therefore, when the continuous line is completely divided, that is, when the adhesive paste is intermittently disposed as in Patent Documents 1 and 2, it is excessively energized at the portion where the adhesive paste is present. The dot part of the film is too vigorous and the film sheet is torn and remains on the paper box side, but in the present invention, the continuous line is not completely divided, so the film sheet is torn off and remains on the paper box side. There is nothing.

また、V字状非接着部はV字の先端方向から二股方向に向かって非接着部が広がるため、当該方向に剥離されやすい。本発明では、V字状非接着部が長手方向中央から短辺方向に向かって凸となるように間隔を開けて配し、短辺方向から長手方向中央に向かって剥離操作がし易い態様としている。   In addition, the V-shaped non-bonded portion is easily peeled off in the direction because the non-bonded portion spreads in the bifurcated direction from the V-shaped tip direction. In the present invention, the V-shaped non-adhesive portion is arranged with an interval so that it protrudes from the center in the longitudinal direction toward the short side direction, and the peeling operation is easy from the short side direction to the center in the longitudinal direction. Yes.

衛生薄葉紙収納箱は、通常、紙箱の短側面が、上面、底面、長側面から延出するフラップを折り畳み封止した封止面となっており、箱解体時にはこの封止面を開封する。そして、フィルムシートを引き剥がす操作は、その封止面を開放した部分から内部に手に入れてフィルムシートを摘み引っ張る操作が行なわれる。よって、引き剥がしの前半は短辺から長手方向中央に向かってフィルムシートが剥離されることになる。引き剥がしの前半、特に初期は、上述の非接着部(V字状非接着部)による勢いを付け難いが、本発明のようにV字状非接着部を配置することで、特にフィルムシート引き剥がし操作の前半、特に初期にスムーズな分離操作が行えるようになる。   In the sanitary thin paper storage box, normally, the short side surface of the paper box is a sealing surface obtained by folding and sealing the flaps extending from the top surface, the bottom surface, and the long side surface, and the sealing surface is opened when the box is disassembled. Then, the operation of peeling off the film sheet is performed by picking up and pulling the film sheet from the portion where the sealing surface is opened. Therefore, in the first half of peeling, the film sheet is peeled from the short side toward the center in the longitudinal direction. In the first half of peeling, especially in the initial stage, it is difficult to apply the momentum due to the above-mentioned non-adhesive part (V-shaped non-adhesive part). A smooth separation operation can be performed in the first half of the peeling operation, particularly in the initial stage.

ここで、本発明においては、V字状非接着部による効果を顕著なものとすべく、V字状非接着部の幅を連続線部分の幅の40〜80%とするのがよい。   Here, in the present invention, in order to make the effect of the V-shaped non-adhered portion remarkable, the width of the V-shaped non-adhered portion is preferably 40 to 80% of the width of the continuous line portion.

また、本発明における糊付けパターンについては、短辺に沿って配される部分の両端が鋸型とすると、上述のフィルムシートの初期、特に最初期の引き剥がし操作がスムーズに行えるようになる。   In the gluing pattern in the present invention, if both ends of the portion arranged along the short side are saw-shaped, the initial and particularly the initial peeling operation of the above-described film sheet can be performed smoothly.

また、本発明に係る糊付けパターンは、連続線が非接着部によって完全に分断されていない非間欠パターンであるため、接着糊を糊版により転写して付与する場合でも、糊版の糊非付与部分に糊粕が溜まり難く、均一塗布が可能である。   In addition, the paste pattern according to the present invention is a non-intermittent pattern in which the continuous line is not completely divided by the non-adhesive portion. Therefore, even when the adhesive paste is transferred and applied with a paste plate, the paste is not applied to the paste plate. It is difficult for glue paste to accumulate on the part, and uniform application is possible.

以上のとおり、本発明によれば、紙箱とフィルムシートの分離性と引き剥がしの操作性に優れる衛生薄葉紙収納箱が提供される。   As described above, according to the present invention, there is provided a sanitary thin paper storage box that is excellent in separability between a paper box and a film sheet and in ease of peeling.

次いで、本発明の実施の形態を図面を参照しながら以下に詳述する。
本発明に係る衛生薄葉紙収納箱1(以下、単に収納箱1ともいう)は、ティシュペーパー、ペーパータオル、キッチンペーパー等の衛生薄葉紙Tをポップアップ式に折り畳み積層した束が収納されるものであり、カートン、カートン箱とも称される。
Next, embodiments of the present invention will be described in detail below with reference to the drawings.
A sanitary thin paper storage box 1 (hereinafter also simply referred to as a storage box 1) according to the present invention stores a bundle of sanitary thin paper T, such as tissue paper, paper towel, kitchen paper, etc., folded and stacked in a pop-up manner. Also called carton box.

本発明に係る収納箱は、図1に示すように、取出し口20Xを形成するための環状に配された裂開用ミシン目線20が設けられた上面11と底面12とこれらに連接する一対の長側面13,13と一対の短側面14,14とを有する直方体形状の紙箱10と、前記裂開用ミシン目線20で囲まれる取出し口形成部20aを紙箱内側から被覆するフィルムシート30とで構成されている。   As shown in FIG. 1, the storage box according to the present invention includes a top surface 11 and a bottom surface 12 provided with a tearing perforation line 20 arranged in an annular shape for forming an extraction port 20 </ b> X, and a pair of them connected to each other. A rectangular parallelepiped paper box 10 having long side surfaces 13, 13 and a pair of short side surfaces 14, 14, and a film sheet 30 that covers the take-out opening forming portion 20 a surrounded by the tearing perforation line 20 from the inside of the paper box. Has been.

紙箱10は、収納箱1の外郭をなす紙製の箱体であり、その大きさ、形状、展開形状等は既知の収納箱の紙箱の構成が採用される。一般的な収納箱の大きさは、概ね長手縁L1が110〜320mm、短手縁L2が70〜200mm、高さL3が40〜150mm程度であり、本発明に係る収納箱1もこの大きさとすることができる。   The paper box 10 is a paper box that forms the outline of the storage box 1, and the construction of the paper box of the known storage box is adopted for the size, shape, developed shape, and the like. The size of a general storage box is approximately 110 to 320 mm for the long edge L1, 70 to 200 mm for the short edge L2, and about 40 to 150 mm for the height L3. The storage box 1 according to the present invention also has this size. can do.

また、紙箱10の素材は、バージンパルプ、古紙パルプ等の各種のパルプを主原料とする既知の紙素材が採用でき、好適な紙箱10の素材は、坪量250〜500g/m2のコートボール紙である。 The paper box 10 may be a known paper material mainly made of various types of pulp such as virgin pulp and waste paper pulp. A suitable paper box 10 material is a coated ball having a basis weight of 250 to 500 g / m 2 . Paper.

本発明に係る紙箱10の構造は、図2、図3に示すように、底面12と一方の長側面13を糊代部12Aで糊付けして筒状とした後、上面11、底面12及びこれらを連接する長側面13から延出する各フラップF,F…を箱内面側に折り返し、各フラップF,F…の当接部分をホットメルト接着剤等により接着して短側面14を構成した構造となっている。なお、本発明の紙箱10は、この構造に限定されるわけではない。   As shown in FIGS. 2 and 3, the structure of the paper box 10 according to the present invention is such that the bottom surface 12 and one long side surface 13 are glued with a glue margin 12A to form a cylinder, and then the top surface 11, the bottom surface 12 and these Flaps F, F... Extending from the long side surface 13 connecting the two are folded back to the inner surface of the box, and the contact portions of the flaps F, F. It has become. The paper box 10 of the present invention is not limited to this structure.

他方、紙箱10の上面に形成される裂開用ミシン目線20は環状をなし、適宜のカットタイ比で構成される。裂開用ミシン目線20は、通常のミシン目線の他、二重ミシン目線、ジッパーミシン目線等で構成することができる。一部分のみ二重ミシン目線としてもよい。   On the other hand, the tearing perforation line 20 formed on the upper surface of the paper box 10 has an annular shape and is configured with an appropriate cut tie ratio. The perforation line 20 for cleaving can be constituted by a double perforation line, a zipper perforation line, or the like in addition to a normal perforation line. Only a part may be a double perforation line.

他方、本実施形態に係る裂開用ミシン目線20は、紙箱長手方向に延在する長辺21,21とこの長辺21,21の端同士を繋ぐ短手縁に平行な短辺22,22とを有し、裂開用ミシン目線20に囲まれる範囲20aの形状は、収納箱1の長手方向に沿う方向が長い適宜の形状である。一般的には、収納箱1の長手方向に沿うやや細長い角取り矩形、或いはその矩形の長辺21,21の中央部を外方に向かってやや膨張させてアーチ状とし、楕円に近い形状としたものである。図示の形態は後者の例である。   On the other hand, the perforation line 20 for tearing according to the present embodiment has long sides 21 and 21 extending in the longitudinal direction of the paper box and short sides 22 and 22 parallel to the short edges connecting the ends of the long sides 21 and 21. The shape of the range 20 a surrounded by the perforation line 20 for tearing is an appropriate shape having a long direction along the longitudinal direction of the storage box 1. In general, a slightly elongated rectangular shape along the longitudinal direction of the storage box 1 or the central part of the long sides 21 and 21 of the rectangle is slightly expanded outward to form an arch shape, and a shape close to an ellipse It is a thing. The illustrated form is the latter example.

他方、フィルムシート30は、裂開用ミシン目線20により囲まれる範囲20aより大きく、紙箱上面の内面側において、裂開用ミシン目線20の切り剥がしに影響がないように、裂開用ミシン目線20の外側で接着されている。   On the other hand, the film sheet 30 is larger than the range 20a surrounded by the tearing perforation line 20, and on the inner surface side of the upper surface of the paper box, the tearing perforation line 20 is not affected. It is glued on the outside.

本発明に係るフィルムシート30の素材は、紙箱10との分別が必要となるものであり、樹脂製或いは樹脂を含むシートである。具体例は、ポリエチレン、ポリプロピレン、ポリエステル等の樹脂からなる樹脂性フィルムシート、又はこれらを積層した積層の樹脂性フィルムシート、フィルムシートと紙等を積層したラミネートフィルムシート、樹脂製繊維からなる合成紙シート等である。取り出し性を考慮すると樹脂製フィルムシートが好ましく、特にポリエチレンフィルムシートが好ましい。   The material of the film sheet 30 according to the present invention requires separation from the paper box 10, and is a sheet made of resin or containing resin. Specific examples are resinous film sheets made of resins such as polyethylene, polypropylene, and polyester, or laminated resinous film sheets obtained by laminating these, laminated film sheets obtained by laminating film sheets and paper, and synthetic paper made of resinous fibers. A sheet or the like. In consideration of the take-out property, a resin film sheet is preferable, and a polyethylene film sheet is particularly preferable.

フィルムシート30の厚みは、15〜200μmが好適である。15μm未満では、強度的に不足し、衛生薄葉紙の取り出し時においてフィルムシート30の裂けあるいは破断の確率が高くなる。逆に、200μmを超えると、フィルムシート30が裂ける等の強度の問題はないものの、衛生薄葉紙取り出し時のひっかかりが大きくなり、薄葉紙が取り出しにくくなったり破れたりする可能性がある。またコスト高ともなる。   The thickness of the film sheet 30 is preferably 15 to 200 μm. If the thickness is less than 15 μm, the strength is insufficient, and the probability of tearing or breaking of the film sheet 30 is increased when the sanitary thin paper is taken out. On the other hand, when the thickness exceeds 200 μm, there is no problem of strength such as tearing of the film sheet 30, but the catch at the time of taking out the sanitary thin paper becomes large, and the thin paper may be difficult to take out or torn. In addition, the cost is high.

他方、フィルムシート30には、スリット31が形成されており、このスリット31は裂開用ミシン目線20により囲まれる範囲20aで長手方向に沿って位置されている。したがって、図4に示すとおり、裂開用ミシン目線20に沿ってその裂開用ミシン目線20で囲まれる範囲20aを切り剥がすことにより、紙箱上面11に取出し口20Xが形成されるとともに、前記フィルムシート30及びそれに形成されたスリット31が取出し口20Xを介して露出される。   On the other hand, a slit 31 is formed in the film sheet 30, and the slit 31 is positioned along the longitudinal direction in a range 20 a surrounded by the tearing perforation line 20. Therefore, as shown in FIG. 4, by cutting off the range 20a surrounded by the tearing perforation line 20 along the tearing perforation line 20, an outlet 20X is formed on the upper surface 11 of the paper box, and the film The sheet 30 and the slit 31 formed on the sheet 30 are exposed through the take-out port 20X.

なお、前記スリット31の長さは、適宜の長さとすることができ、既知の環状ミシン目線20との大きさの関係で適するとされる長さが採用できる。   In addition, the length of the said slit 31 can be made into an appropriate length, and the length considered suitable in relation to the magnitude | size with the known annular perforation line 20 is employable.

収納箱1に束として収納されているティシュペーパー等の衛生薄葉紙Tは、図示例のとおり、前記スリット31を介して取出し口20Xから一枚ずつ取り出される。そして、当該スリット31は、取出し口20Xから露出するティシュペーパー等の衛生薄葉紙Tの一部を支持して収納箱内部に落ち込むことを防止する。   The sanitary thin paper T such as tissue paper stored as a bundle in the storage box 1 is taken out one by one from the take-out port 20X through the slit 31 as shown in the drawing. And the said slit 31 supports a part of sanitary thin paper T, such as tissue paper exposed from the taking-out opening 20X, and prevents falling into the inside of a storage box.

ここで、本発明に係る収納箱1は、図5に示すように、フィルムシート30を紙箱内面に貼付するための接着糊40の糊付けパターンが、裂開用ミシン目線20で囲まれる範囲20aを包囲するようにして裂開用ミシン目線20の長辺21,21及び短辺22,22に沿って接着糊40が配され、かつ、その長辺21,21に沿って配される部分41,41が連続線内に長手方向中央から短辺方向に向かって凸のV字状非接着部41v,41vが間隔を開けて複数設けられているパターンとなっている。   Here, as shown in FIG. 5, the storage box 1 according to the present invention has a range 20 a in which the paste pattern of the adhesive paste 40 for attaching the film sheet 30 to the inner surface of the paper box is surrounded by the perforation line 20 for tearing. The adhesive paste 40 is disposed along the long sides 21 and 21 and the short sides 22 and 22 of the tearing perforation line 20 so as to surround the portion 41 and the portions 41 and 21 disposed along the long sides 21 and 21. 41 is a pattern in which a plurality of V-shaped non-adhesive portions 41v, 41v protruding from the center in the longitudinal direction toward the short side direction are provided in a continuous line at intervals.

収納箱1は、上述のとおり、紙箱10の短側面14が、上面11、底面12、長側面13から延出するフラップF,F…を折り畳み封止した封止面となっており、箱解体時には図3に示されるように、この封止面である短側面14を開封する。そして、フィルムシート30を引き剥がす操作は、その封止面を開封した部分から内部に手に入れてフィルムシート30を摘み引っ張るようにして行なわれる。よってV字状非接着部41vを長手方向中央から短辺22方向に向かって凸となるように配置することで、一対の短側面14,14のいずれの短側面がわからであっても、スムーズにフィルムシート30の引き剥がしが行えるようになる。なお、図示例では、長辺21に沿う部分41の長手方向中央を対称軸として対称にV字状非接着部41v,41vが配置されているが、必ずしも対称である必要はない。   In the storage box 1, as described above, the short side surface 14 of the paper box 10 is a sealing surface obtained by folding and sealing the flaps F, F... Extending from the top surface 11, the bottom surface 12, and the long side surface 13, Sometimes, as shown in FIG. 3, the short side surface 14 as the sealing surface is opened. And operation which peels off the film sheet 30 is performed so that it may get inside from the part which opened the sealing surface, and may be picked and pulled. Therefore, by arranging the V-shaped non-adhesive portion 41v so as to protrude from the center in the longitudinal direction toward the short side 22 direction, even if any short side of the pair of short side surfaces 14 and 14 is known, smooth In addition, the film sheet 30 can be peeled off. In the illustrated example, the V-shaped non-adhesive portions 41v and 41v are arranged symmetrically with the longitudinal center of the portion 41 along the long side 21 as the axis of symmetry, but it is not necessarily required to be symmetrical.

他方、図示の形態では、長辺21がアーチ状であり、長辺21に沿う部分41のパターンも外方にやや膨出するアーチ状としているがこれに限定されるわけではない。また、図示の形態では、前記長辺21に沿って配される部分41が、前記短辺22に沿って配される部分42の端より中央寄り位置に連なるパターンとなっているが必ずしもこれに限定されない。   On the other hand, in the illustrated form, the long side 21 has an arch shape, and the pattern of the portion 41 along the long side 21 has an arch shape that slightly bulges outward, but is not limited thereto. Further, in the illustrated form, the portion 41 arranged along the long side 21 is a pattern continuous to the center position from the end of the portion 42 arranged along the short side 22. It is not limited.

この本発明に係る糊付けパターンは、より好ましくは、裂開用ミシン目線20との間隔が、長辺21との間の距離L4が2〜15mm、短辺22との間の距離L5が2〜10mmであるのがよい。過度に離れていると広い面積のフィルムシート30が必要となりコスト高となる。また、距離が近いと製造時に糊が裂開用ミシン目線20に付着するおそれがある。   More preferably, in the gluing pattern according to the present invention, the distance to the perforation line 20 is 2 to 15 mm for the distance L4 to the long side 21 and 2 to 5 for the distance L5 to the short side 22. It should be 10 mm. If it is excessively separated, a film sheet 30 having a large area is required, resulting in an increase in cost. If the distance is short, the glue may adhere to the perforation line 20 for cleavage.

また、連続線41Lの幅L6は好適には0.5〜5.0mmであり、より好適には2.0〜4.0mmである。幅が5.0mm未満であると全体として接着が不十分になるおそれがあり、5.0mm以上であると引き剥がしの際の過度の力を要するようになる。   The width L6 of the continuous line 41L is preferably 0.5 to 5.0 mm, and more preferably 2.0 to 4.0 mm. If the width is less than 5.0 mm, adhesion as a whole may be insufficient. If the width is 5.0 mm or more, an excessive force is required for peeling.

他方、V字状非接着部41vは、フィルムシート30が紙箱10に対して接着されていない部分であり、接着糊40の非付与部分として形成することができる。V字状に糊殺し処理することで形成してもよい。非接着性の付与態様は既知の技術によって適宜行なうことができる。   On the other hand, the V-shaped non-adhesive portion 41v is a portion where the film sheet 30 is not adhered to the paper box 10, and can be formed as a non-applied portion of the adhesive paste 40. It may be formed by paste-killing in a V shape. The non-adhesive application mode can be appropriately performed by a known technique.

V字状非接着部41vのより具体的な形状は、線で描かれる単純なV字であってもよいが、図示される幅方向中央から二股部分に向かって狭窄してなる、V字の各三端を頂点とする凹四角形であるのが望ましい。この形状は、V字先端がわの非接着面積が広く、そこから二股の各端に非接着部が分かれ徐々に非接着部が狭くなる。よって、最初にV字先端側が剥離されやすくV字先端がわから二股端方向に剥離が進行しやすい。なお、V字状非接着部は、上記形状に限定されず、その他に図8(a)に示す矢羽根形状、(b)に示すV字の凸端が鋭利ではない略三日月型、(c)に示すハート型も含まれる。   A more specific shape of the V-shaped non-adhesive portion 41v may be a simple V-shape drawn with a line, but the V-shape non-adhesive portion 41v narrows from the center in the width direction toward the forked portion. It is desirable that it is a concave rectangle with the three ends as apexes. In this shape, the non-adhesive area of the V-shaped tip is wide, and the non-adhesive portion is divided at each end of the fork to gradually narrow the non-adhesive portion. Therefore, the V-shaped tip side is likely to be peeled off first, and the peeling is likely to proceed in the forked end direction from the V-shaped tip. The V-shaped non-adhesive portion is not limited to the above-mentioned shape. In addition, an arrow-blade shape shown in FIG. 8A, a substantially crescent shape whose V-shaped convex end shown in FIG. 8B is not sharp, (c The heart shape shown in () is also included.

また、V字状非接着部41vは、その幅L7が連続線41Lの幅L6よりも幅狭であり、連続線41L内に位置している。すなわち、V字状非接着部41vは、連続線41Lの両幅縁と交わらない。   Further, the V-shaped non-adhesive portion 41v has a width L7 narrower than the width L6 of the continuous line 41L, and is located within the continuous line 41L. That is, the V-shaped non-adhesive portion 41v does not intersect with both width edges of the continuous line 41L.

特に、本発明ではV字状非接着部41vの幅L7は、連続線41Lの幅L6の40〜80%であるのが好ましく、50〜70%がより好ましい。連続線41Lの幅L6の40%未満では、フィルムシート30の引き剥がし時に、V字状非接着部41vの部分で勢いが付かず、隣接するV字状非接着部間の部分との差が発現し難い。また、80%を超えると、接着糊を間欠配置するのと同様にフィルムシート30の一部がちぎれて残るおそれが高まる。   In particular, in the present invention, the width L7 of the V-shaped non-adhesive portion 41v is preferably 40 to 80% of the width L6 of the continuous line 41L, and more preferably 50 to 70%. If it is less than 40% of the width L6 of the continuous line 41L, when the film sheet 30 is peeled off, there is no momentum in the V-shaped non-adhesive portion 41v, and there is a difference between the adjacent V-shaped non-adhesive portions. It is difficult to express. Moreover, when it exceeds 80%, the possibility that a part of the film sheet 30 may be torn off and remain as in the case where the adhesive paste is intermittently disposed increases.

また、V字状非接着部41vの長さL8は、2.0〜10mm、好ましくは3.0〜5.0mmである。上記範囲を超えるとV字状に非接着部を設ける効果が得られなくなる。   Further, the length L8 of the V-shaped non-bonding portion 41v is 2.0 to 10 mm, preferably 3.0 to 5.0 mm. If the above range is exceeded, the effect of providing a non-adhesive portion in a V shape cannot be obtained.

また、本発明の収納箱1では、隣接するV字状非接着部間の間隔L9は、好適には20〜40mmである。20mm未満であると、接着力が強くなりすぎてスムーズに引き剥がせなくなるおそれが高まる。反対に40mmを超えると非接着部分を設ける効果が小さくなる。   Moreover, in the storage box 1 of this invention, the space | interval L9 between adjacent V-shaped non-adhesion parts is 20-40 mm suitably. If it is less than 20 mm, the adhesive strength becomes too strong, and there is an increased possibility that it cannot be peeled off smoothly. On the contrary, if it exceeds 40 mm, the effect of providing a non-adhesive part will become small.

V字状非接着部41vの個数は、特に限定されない。裂開用ミシン目線20の長辺11の長さに応じて適宜の個数設けることができる。なお、一般的な収納箱1では裂開用ミシン目線20で囲まれる範囲の長手方向長さが200mm前後であり、この場合には6〜 10点程度等間隔で配置するようにすればよい。   The number of V-shaped non-adhesive portions 41v is not particularly limited. An appropriate number can be provided according to the length of the long side 11 of the perforation line 20 for cleavage. In addition, in the general storage box 1, the length in the longitudinal direction of the range surrounded by the perforation line 20 for tearing is around 200 mm, and in this case, it may be arranged at about 6 to 10 points at equal intervals.

他方、本発明に係る接着糊40の糊付けパターンは、より好ましくは短辺22に沿って配される部分42をやや幅広の線状とし、その両端を鋸型とするのが望ましい(鋸型部分を図5中符号43で示す)。短辺22に沿う部分42の幅L10は、5〜7mmが適する。図示例は、特に好ましく、鋸型の刃先方向が短辺の延在方向よりもやや短手面方向に向かうように角度付けされている。当該角度∠Aの具体的な角度は限定されないが短辺延在方向に対して10〜80°の範囲であれば十分である。上述のとおりフィルムシートの引き剥がしは、短側面14を開放して行なわれるのが一般的であり、その際にはフィルムシート30の短側面14がわの中央部を摘んで引っ張る操作が行なわれることが多い。このように中央部を摘んでフィルムシートを引き剥がすべく引っ張ると、接着糊の配設位置のうち特に短辺22に沿って配される部分42に力が加わる。よって、当該位置を鋸型としておくと、引き剥がしの最初期にフィルムシートがスムーズに分離されるようになる。   On the other hand, in the gluing pattern of the adhesive paste 40 according to the present invention, it is more preferable that the portion 42 arranged along the short side 22 is a slightly wider line and both ends thereof are saw-shaped (saw-shaped portion). (Denoted by reference numeral 43 in FIG. 5). The width L10 of the portion 42 along the short side 22 is suitably 5 to 7 mm. The illustrated example is particularly preferred, and is angled so that the saw-shaped cutting edge direction is slightly shorter than the extending direction of the short side. The specific angle of the angle ∠A is not limited, but it is sufficient if it is in the range of 10 to 80 ° with respect to the short side extending direction. As described above, the film sheet is generally peeled off by opening the short side surface 14, and in this case, an operation is performed in which the short side surface 14 of the film sheet 30 picks and pulls the center portion of the hook. There are many cases. Thus, when the center portion is picked and pulled to peel off the film sheet, a force is applied to the portion 42 arranged along the short side 22 in the position where the adhesive paste is disposed. Therefore, if the position is a saw shape, the film sheet is smoothly separated at the initial stage of peeling.

なお、本発明に係る収納箱1は、短側面14に指入れ用のミシン目線を設けるなど、封止面を開放しやすくして箱解体を容易にならしめる既知の機構を採用することができる。   The storage box 1 according to the present invention can employ a known mechanism that facilitates opening of the sealing surface and facilitating box disassembly, such as providing a perforation line for finger insertion on the short side surface 14. .

他方、接着糊41の具体的種類は特に限定されない。ホットメルト接着剤が使用できる。リサイクルの点では水性接着剤が好適である。   On the other hand, the specific type of the adhesive paste 41 is not particularly limited. Hot melt adhesives can be used. A water-based adhesive is preferable in terms of recycling.

また、フィルムシート30と紙箱1との具体的な接着力(剥離強度)は、フィルムシート30の剛性、紙箱の材質などを考慮して適宜さだめることができ、限定されないが 0.5〜2kgfの範囲で設計するのがよい。   Moreover, the specific adhesive force (peeling strength) between the film sheet 30 and the paper box 1 can be appropriately determined in consideration of the rigidity of the film sheet 30 and the material of the paper box, and is not limited to 0.5 to 2 kgf. It is better to design within the range.

本発明の実施例と従来例とについて、紙箱とフィルムシートの分離性に関して試験を行なった。本発明の実施例に係る接着剤40の糊付けパターンは、図5に示すとおりであり、連続線41Lの幅L6は4.0mm、V字状非接着部41vの幅L7は3.0mm、長さL8は4.0mm、V字状非接着部間に間隔L9は25mm、接着糊40の裂開用ミシン目線20の短辺22に沿って配される部分の幅L10は6.0mmとした。   About the Example of this invention, and the prior art example, it tested about the separability of a paper box and a film sheet. The pasting pattern of the adhesive 40 according to the embodiment of the present invention is as shown in FIG. 5, the width L6 of the continuous line 41L is 4.0 mm, and the width L7 of the V-shaped non-adhesive portion 41v is 3.0 mm. The length L8 is 4.0 mm, the distance L9 between the V-shaped non-bonded portions is 25 mm, and the width L10 of the portion disposed along the short side 22 of the perforation line 20 of the adhesive paste 40 is 6.0 mm. .

比較例1に係る接着剤の糊付けパターンは、図6に示すとおりV字状非接着部を設けない例であり、接着糊の裂開用ミシン目線の長手に沿って配される部分の幅L6は3.5mm、接着糊の裂開用ミシン目線の短辺に沿って配される部分の幅L10は6mmである。図6中、実施例と同様の部分は同様の符号を付する。   The adhesive glueing pattern according to Comparative Example 1 is an example in which no V-shaped non-adhesive portion is provided as shown in FIG. 6, and the width L6 of the portion arranged along the length of the perforation line for tearing the adhesive paste Is 3.5 mm, and the width L10 of the portion arranged along the short side of the perforation line for tearing the adhesive paste is 6 mm. In FIG. 6, the same parts as those in the embodiment are denoted by the same reference numerals.

比較例2に係る接着糊の糊付けパターンは、図7に示すとおりであり、接着糊を間欠的に設け、取出し口を矩形に囲んだものである。なお、非糊付与部分の長さL13が4mm、糊付け部分の長さL14が4mm、幅L15が2mmである。図7中の実施例と同様の部分は同様の符号を付する。   The adhesive glue pasting pattern according to Comparative Example 2 is as shown in FIG. 7, in which adhesive glue is provided intermittently and the take-out port is surrounded by a rectangle. The length L13 of the non-glue-applied part is 4 mm, the length L14 of the glued part is 4 mm, and the width L15 is 2 mm. Portions similar to those of the embodiment in FIG.

紙箱とフィルムシートの分離性は、試料30個について一方短辺から他方短辺に向かって紙箱からフィルムシートを引き剥がす操作を行ない、1cm四方以上のちぎれたフィルムシートが紙箱に残存した個数を計数してその割合を算出した。   The separation between the paper box and the film sheet is performed by peeling the film sheet from the paper box from one short side to the other short side for 30 samples, and counting the number of film sheets that are torn off by 1 cm square or more in the paper box. The ratio was calculated.

表1に示されるとおり、本発明の実施例は、フィルムシートの分離性について、比較例1、2より良好な結果となった。   As Table 1 shows, the Example of this invention brought the result better than Comparative Examples 1 and 2 about the separability of a film sheet.

以上のことから、本発明の実施形態は、紙箱とフィルムシートの分離性に優れる衛生薄葉紙収納箱である。   From the above, the embodiment of the present invention is a sanitary thin paper storage box having excellent separation between a paper box and a film sheet.
