Description

本発明は、カット紙タイプの衛生シートセット積層体を収納するフィルム包装体から衛生シートを取り出しやすくすること、衛生シートセットの落ち込みを防止することを目的とした新たな取り出し口形状のフィルム包装体に関する。 The present invention is a new outlet-shaped film package for the purpose of facilitating the removal of the sanitary sheet from the film package for accommodating the cut paper type sanitary sheet set laminate and preventing the sanitary sheet set from falling. Regarding.

従来、フィルムや紙等の素材から作られた袋や箱に、家庭用薄葉紙(ティッシュペーパーやトイレットペーパー)やペーパータオル、キッチンペーパー、各種ワイパー等が交互に折り畳まれたシート積層体を収納し、内容物であるシート積層体の使用に際しては、適宜開封口から必要量がポップアップ式にカットされたシートが引き出され使用される。内容物である衛生シート積層体を包装し保護するフィルム等から作られた包装体では、ピロー包装やマチ付きのガゼット包装、合わせ包み(キャラメル包装)等の形態が一般的に使用されることが多く、開口部である開封口にはミシン目が付与され容易に開封できる構造となっていることが多い。また、衛生シートセットは、1枚から4枚重ねのものが一般的であり、必要によりエンボス加工や保湿剤の塗布、印刷加工等が施される。 Conventionally, in a bag or box made of materials such as film or paper, a sheet laminate in which household thin paper (tissue paper or toilet paper), paper towels, kitchen paper, various wipers, etc. are alternately folded is stored, and the contents are stored. When using the sheet laminate, which is a product, a sheet in which the required amount is cut in a pop-up manner is appropriately pulled out from the opening and used. For packaging made from a film that wraps and protects the sanitary sheet laminate, which is the content, forms such as pillow packaging, gusseted gusset packaging, and combined packaging (caramel packaging) are generally used. In many cases, the opening, which is the opening, is perforated so that the opening can be easily opened. In addition, the sanitary sheet set is generally one to four layers, and if necessary, embossing, application of a moisturizer, printing, etc. are performed.

前記のフィルム等から作られた包装体開口部から内容物を1セットずつ取り出して使われるが、使用初めには内容物である衛生シートセット積層体が圧縮された状態でありスリット状の取り出し口から取り出し難いことがある。初期の取り出しやすさを考慮してスリットの長さを長くすると逆に衛生シート積層体の残量が少なくなった場合には衛生シートセットの前後のセット同士の摩擦抵抗が弱くなり次に出るべき衛生シートセットが包装体内部に残ってしまい、ポップアップ式に取り出すことができない問題が発生してしまうことが多い。 The contents are taken out one by one from the opening of the package made from the above-mentioned film or the like and used, but at the beginning of use, the sanitary sheet set laminate which is the contents is in a compressed state and has a slit-shaped take-out port. It may be difficult to remove from. If the length of the slit is increased in consideration of the initial ease of removal, on the contrary, if the remaining amount of the sanitary sheet laminate becomes low, the frictional resistance between the front and rear sets of the sanitary sheet set becomes weak and should be released next. In many cases, the sanitary sheet set remains inside the package and cannot be taken out in a pop-up manner.

以下に図面を参照しながら本発明を実施するための形態(以下、実施形態)について具体的に説明する。 Hereinafter, embodiments for carrying out the present invention (hereinafter, embodiments) will be specifically described with reference to the drawings.

図1〜図5を参照しながら本発明に係わるフィルム包装体の第1実施形態を具体的に説明する。図1は、合わせ包み(キャラメル包装)の一例を示したもので、図1に示したフィルム包装体は図3の上面図と同じで衛生シートの取り出し口がA、B1、B2のように配置されており、図3ではそれらの開口部の長さa、b1、b2を示している。図1および図3は、一例として開口部Aの部分がミシン目で構成され、開口部B1および開口部B2がスリットで構成されており、開口部Aのミシン目を開裂させることにより横に伸びたH字形状の開口部となる。このミシン目部分は開裂させやすいようにミシン目のタイカット比率を部分的に変えても良く、さらにはミシン目ではなく光や熱でフィルムを薄くすることや部分的に強度を低下させることで開裂させる部分を形成させても良い。また、開口部B1、B2はスリットではなく開口部Aの部分と同様の処理を行ったミシン目形状でも良い。このような横に伸びたH状の開口部とすることにより、開口部Aの部分を開裂させて開口部B1あるいは開口部B2に開裂端が至った時に開口部B1あるいは開口部B2を超えて長側面方向にフィルムが破断することがなく、開口部の形状が適切に保持される。本発明の包装体の説明では、合わせ包みの形態を用いて説明しているが、ピロー包装やマチ付きのガゼット包装等、衛生シートセット積層体を包装できる形態であれば良く、合わせ包みに限定するものではない。 The first embodiment of the film package according to the present invention will be specifically described with reference to FIGS. 1 to 5. FIG. 1 shows an example of combined wrapping (caramel wrapping). The film wrapping body shown in FIG. 1 is the same as the top view of FIG. In FIG. 3, the lengths a, b1 and b2 of those openings are shown. In FIGS. 1 and 3, as an example, the portion of the opening A is formed of perforations, the opening B1 and the opening B2 are formed of slits, and the perforations of the opening A are cleaved to extend laterally. It becomes an H-shaped opening. The tie-cut ratio of the perforations may be partially changed so that the perforations can be easily cleaved, and further, by thinning the film with light or heat instead of the perforations or partially reducing the strength. A portion to be cleaved may be formed. Further, the openings B1 and B2 may have a perforated shape obtained by performing the same processing as the portion of the opening A instead of the slit. By forming such a laterally extending H-shaped opening, when the portion of the opening A is cleaved and the cleft end reaches the opening B1 or the opening B2, the opening B1 or the opening B2 is exceeded. The film does not break in the long side direction, and the shape of the opening is properly maintained. In the description of the package of the present invention, the form of the combined wrapping is used, but any form such as pillow packaging or gusseted gusset packaging that can wrap the sanitary sheet set laminate is sufficient, and the package is limited to the combined wrapping. It's not something to do.

図2は、従来のフィルム包装体から衛生シートセットが取り出されている状態を短側面方向から見た時の断面図で、開口部がAのスリットだけの場合を示しており、図4は、図2と同様の従来のフィルム包装体から衛生シートセットを1セットずつ取り出す状態を上面側および短側面側から見た図で、衛生シートセットを容易に取り出すためにスリット状の開口部が長くなければならないことを示している。開口部が短い場合は衛生シートセットがスリット部分を通過する時にシート幅が狭められて多くのしわが発生し抵抗が増加するため取り出し難くなる。無理に取り出そうとすると衛生シートセットが破れることやスリット状の開口部端が裂けてしまう場合があり好ましくない。さらに、図4のように開口部が長いスリット状の場合は衛生シートセットの残数が少なくなると取り出し中の衛生シートセットと次の衛生シートセットの接触が弱まりポップアップ式に取り出そうとしても次のシートがフィルム包装体内部に残ってしまう問題が生じやすい。 FIG. 2 is a cross-sectional view of a state in which the sanitary sheet set is taken out from the conventional film package when viewed from the short side surface, and shows a case where the opening is only the slit of A. FIG. It is a view from the upper surface side and the short side surface side that the sanitary sheet set is taken out one by one from the conventional film package similar to FIG. 2, and the slit-shaped opening must be long in order to easily take out the sanitary sheet set. Indicates that it must be done. If the opening is short, when the sanitary sheet set passes through the slit portion, the sheet width is narrowed, many wrinkles are generated, and resistance is increased, which makes it difficult to remove. If you try to take it out forcibly, the sanitary sheet set may be torn or the slit-shaped opening end may be torn, which is not preferable. Further, in the case of a slit shape with a long opening as shown in FIG. 4, when the remaining number of the sanitary sheet set becomes small, the contact between the sanitary sheet set being taken out and the next sanitary sheet set weakens, and even if the sanitary sheet set is taken out in a pop-up manner, the next The problem that the sheet remains inside the film package is likely to occur.

図5は、図1および図3のフィルム包装体の開口部AおよびB1、B2を開裂させて上面および短側面方向から衛生シートセットを取り出す過程を左から右方向に順番に示したもので、衛生シートセットの形状変化を示した。符号11の上面図から見た場合に衛生シートセットが開口部で逆コの字型になっており、長側面の長さLに対してaの長さが短くてもシートセット幅Wが開口部に納まることに加え、直線状の場合に比べ衛生シートセット同士の摩擦抵抗が大きくなるため、衛生シートセット残数が少なくなっても取り出し中の衛生シートセットと次の衛生シートセットの抵抗低下が少なく安定してポップアップ式に取り出すことができる。また、開封時の衛生シートセットの取り出しにおいても開口部の面積が広くなっていることで1セット目を指で掴みやすくかつ取り出し時にフィルムとの抵抗が小さいため容易に取り出すことができる。 FIG. 5 shows the process of opening the openings A, B1 and B2 of the film packaging of FIGS. 1 and 3 and taking out the sanitary sheet set from the upper surface and the short side surface in order from left to right. The shape change of the sanitary sheet set was shown. When viewed from the top view of reference numeral 11, the sanitary sheet set has an inverted U shape at the opening, and the sheet set width W is open even if the length of a is shorter than the length L of the long side surface. In addition to fitting in the part, the frictional resistance between the sanitary sheet sets is larger than in the case of a straight line, so even if the remaining number of sanitary sheet sets is small, the resistance between the sanitary sheet set being taken out and the next sanitary sheet set is reduced. It can be taken out in a pop-up manner with little. Further, even when the sanitary sheet set is taken out at the time of opening, the wide opening area makes it easy to grasp the first set with fingers and the resistance to the film at the time of taking out is small, so that the sanitary sheet set can be easily taken out.

図5をより詳しく説明すると、符号11の上面から見た衛生シートセットは逆コの字型であるが、その状態から衛生シートセットを1セット取り出した符号13の状態では衛生シートセットがコの字型になり、この状態からさらに衛生シートセットを1セット取り出すと符号15の状態つまり符号11の状態のようになる。図5は、これらが繰り返されて衛生シートセットが取り出されていくことを説明した図である。符号12、14、16は短側面から衛生シートセットを1セットずつ散り出した時の変化を示したもので、短側面から見た時に開口部の左右の方形部が開閉し、開口部の面積を小さくすることで異物が入り難くなるメリットもある。さらに本発明の開口部は線状の取り出し口が連接した形状であるため、面上の閉じた線で囲まれた開口部を切り取るようなことがなく開口部を作る際にフィルム片つまりゴミが発生しないメリットがある。さらに、衛生シートセットが立った状態で保持されるため取り出しやすいメリットもある。加えて衛生シートセットが取り出し口から立った状態で保持されるため取りやすいメリットがある。 To explain FIG. 5 in more detail, the sanitary sheet set viewed from the upper surface of reference numeral 11 has an inverted U shape, but in the state of reference numeral 13 in which one set of sanitary sheet sets is taken out from that state, the sanitary sheet set is U-shaped. It becomes a character shape, and when one set of sanitary sheet sets is taken out from this state, it becomes the state of reference numeral 15, that is, the state of reference numeral 11. FIG. 5 is a diagram illustrating that the sanitary sheet set is taken out by repeating these steps. Reference numerals 12, 14 and 16 indicate changes when the sanitary sheet sets are scattered one by one from the short side surface. When viewed from the short side surface, the left and right square portions of the opening open and close, and the area of the opening is widened. There is also an advantage that foreign matter is hard to enter by making the size smaller. Further, since the opening of the present invention has a shape in which linear outlets are connected to each other, a film piece, that is, dust, is generated when the opening is made without cutting off the opening surrounded by the closed line on the surface. There is a merit that it does not occur. Furthermore, since the sanitary sheet set is held in an upright position, it has the advantage of being easy to take out. In addition, the sanitary sheet set is held upright from the take-out port, which has the advantage of being easy to remove.

ポップアップ式の衛生シートセット積層体の製造方法について簡単に説明すると、カートンボックスやフィルム包装されたソフトパック等に入っているティッシュペーパーは、一般的に長方形に断裁され二つ折りされたシートが交互に向かい合った形で折り重なっており、前のシートの内側に後のシートの前部略半分が挿入された状態になって重なっている。マルチスタンド方式での生産では、所定の幅に断裁されたシートロールが必要な数並べられ、それらがシートの流れ方向に送られながら交互に重なった状態に折り畳まれた連続した積層体が形成される。これを所定の長さに断裁することでポップアップ式の積層体を作ることができる。また、2本のロールから供給されるシートを交互に断裁しながら折り畳むことでポップアップ式の積層体を作るインターフォルダ方式の加工機を用いてもポップアップ式の積層体を作ることができる。 To briefly explain the manufacturing method of the pop-up type sanitary sheet set laminate, the tissue paper contained in a carton box, a soft pack wrapped in a film, etc. is generally cut into a rectangle and folded in half alternately. It is folded so that it faces each other, and the front half of the rear seat is inserted inside the front seat. In multi-stand production, the required number of sheet rolls cut to a predetermined width are lined up, and they are fed in the flow direction of the sheet to form a continuous laminated body that is folded in an alternating state. To. A pop-up type laminate can be made by cutting this into a predetermined length. Further, a pop-up type laminate can also be produced by using an interfolder type processing machine for producing a pop-up type laminate by alternately cutting and folding the sheets supplied from the two rolls.

包装体を構成するフィルム基材としでは、ポリエチレン(PE)樹脂、ポリプロピレン(PP)樹脂、ポリエチレンテレフタレート(PET)樹脂等が好適であるが、可撓性があり被包装体の保管・保護に適した樹脂フィルムであれば使用可能である。これらフィルムは必要により積層したり、表面への樹脂塗工や金属蒸着等により改質して用いてもよい。また、内容物の隠蔽性を高めるために樹脂中に炭酸カルシウム等の顔料を添加してもよく、印刷により隠蔽性を高めたり、視認性を高めて使用することもできる。 As the film base material constituting the package, polyethylene (PE) resin, polypropylene (PP) resin, polyethylene terephthalate (PET) resin and the like are suitable, but they are flexible and suitable for storage and protection of the packaged object. Any resin film can be used. If necessary, these films may be laminated, or modified by resin coating on the surface, metal vapor deposition, or the like. Further, a pigment such as calcium carbonate may be added to the resin in order to enhance the concealing property of the contents, and the concealing property may be enhanced by printing or the visibility may be enhanced.

包装体に使用される可撓性のあるフィルムの厚み(JIS P 8118:2014測定)については、20μm〜80μmの範囲であることが好ましく、より好ましくは25μm〜60μmの範囲である。20μm未満であると一般的にフィルム強度が低くなり、ミシン目加工や熱融着加工時に破断や穴あき等のトラブルを発生させやすい。また、80μmを超えるとフィルムコストが高くなり実用的でないことに加え、可撓性の低下によりフィルムを使用した場合の柔軟性のメリットの消失や熱融着時の熱伝導性低下による加工不良等の問題が生じやすく実用的でない。 The thickness of the flexible film used for the packaging (measured by JIS P 8118: 2014) is preferably in the range of 20 μm to 80 μm, more preferably in the range of 25 μm to 60 μm. If it is less than 20 μm, the film strength is generally low, and troubles such as breakage and perforation are likely to occur during perforation processing and heat fusion processing. Further, if it exceeds 80 μm, the film cost becomes high and it is not practical. In addition, the merit of flexibility when the film is used disappears due to the decrease in flexibility, and the processing defect due to the decrease in thermal conductivity at the time of heat fusion, etc. Is prone to problems and is not practical.

本発明の衛生シートは、家庭用薄葉紙(ティッシュペーパーやトイレットペーパー)やペーパータオル、キッチンペーパー、各種ワイパー等を指し、これらの原料として一般的には木材パルプが用いられるが、各種植物性繊維や古紙パルプ、各種パルプと合成繊維を混抄したシートや不織布等のシートが使用可能であり、必要によりこれらのシートは、多数枚重ね(多数プライ)たり、エンボス加工して使用される。これらのシートは、薄いものでは2〜4枚程度を重ねたシートが使用されることが多いが、特に4枚以内に限定するものではない。また、これらのシートとして保湿剤や滅菌・殺菌剤、界面活性剤、芳香剤、滑剤等を含ませた機能性シートを用いても良く、本包装体は多様なシートを内容物として包装することができる。積層体を構成する衛生シートの一般的な寸法としては、人の手で取り出して拭く、包む等に使われるものであるため、その大きさは折らない状態で1辺が60mm〜250mm程度である場合が多い。 The sanitary sheet of the present invention refers to household thin paper (tissue paper or toilet paper), paper towels, kitchen paper, various wipers, etc., and wood pulp is generally used as a raw material for these, but various vegetable fibers and used paper. Sheets such as pulp, sheets obtained by mixing various types of pulp and synthetic fibers, and non-woven fabrics can be used, and if necessary, these sheets are used by stacking a large number of sheets (many plies) or embossing them. As these sheets, thin sheets are often used in which about 2 to 4 sheets are stacked, but the number is not particularly limited to 4 sheets or less. Further, as these sheets, a functional sheet containing a moisturizer, a sterilizer / bactericide, a surfactant, a fragrance, a lubricant, etc. may be used, and the present package should be packaged with various sheets as contents. Can be done. The general dimensions of the sanitary sheet that composes the laminate are that it is used for manual removal, wiping, wrapping, etc., so its size is about 60 mm to 250 mm on a side without folding. In many cases.

フィルムに開口部や開裂可能なミシン目を入れる方法としては、金属製の刃型やミシン刃あるいは抜き型を当てて開裂部やミシン目部分を作る方法、レーザー光等の高出力光源等を用いて局所的にフィルムを加熱しカット部や薄い部分を作る方法等がある。レーザー光を用いた場合には、出力の調整によりフィルムに加える熱量を変えて完全なカット部やフィルムを薄くした部分を容易に作ることができる。加えて、横長のH字形状の端部4箇所の端を円形やJ字状の止め形状にすると開口部に大きな力が加わっても力が分散されてフィルムの開口部が破断して広がるようなトラブルが生じ難くなる。 As a method of making openings and perforations in the film, a metal blade, a perforation blade, or a punch is applied to make a fissure or a perforation, or a high-power light source such as laser light is used. There is a method of locally heating the film to make a cut part or a thin part. When laser light is used, it is possible to easily make a complete cut portion or a thinned portion of the film by changing the amount of heat applied to the film by adjusting the output. In addition, if the four horizontally long H-shaped ends are made into a circular or J-shaped stop shape, the force will be dispersed even if a large force is applied to the opening, and the opening of the film will break and expand. Trouble is less likely to occur.

第2実施形態として、図6〜図9に具体的実施例を示した。図6〜図9は、図3の派生形で、開裂部B1およびB2を一直線状ではなく、Aとの交点を頂点とした山型形状やかまぼこ型形状、波型形状等、デザイン面も考慮して開口部を作ることができることを示した。その場合は、(a−k)/2の値が、10mm程度以下が好ましく、より好ましくは5mm以下である。これらの形状は衛生シートセット同士の抵抗が低い場合には抵抗を増加させて安定して衛生シートセットを取り出す効果的な方法となる。逆に10mm以上であれば凸部と衛生シートセットとの抵抗が大きくなりすぎて衛生シートセットが抜き取られて交互にコの字から逆コの字に変わる時にスムーズに移行しなくなる場合がある。 As the second embodiment, specific examples are shown in FIGS. 6 to 9. 6 to 9 are derivative forms of FIG. 3, and the design aspects such as a chevron shape, a semi-cylindrical shape, and a corrugated shape having the intersection with A as the apex are taken into consideration, instead of the cleavage portions B1 and B2 being linear. It was shown that an opening could be made. In that case, the value of (ak) / 2 is preferably about 10 mm or less, more preferably 5 mm or less. These shapes are effective methods for stably taking out the sanitary sheet set by increasing the resistance when the resistance between the sanitary sheet sets is low. On the contrary, if it is 10 mm or more, the resistance between the convex portion and the sanitary sheet set becomes too large, and when the sanitary sheet set is pulled out and alternately changes from a U-shape to an inverted U-shape, the transition may not be smooth.

以下の表1では、図3の開口部の形状でフィルム基材がポリエチレン素材、厚みが50μmのフィルムを使用し、その他の条件は表に記載の寸法として衛生シートセット積層体の合わせ包み包装品を作製し、取り出しやすさの感応評価と取残しセット数を基に評価を実施した。またB1とB2部分の形状、長さは対称で同じ長さの方がデザイン的に良いため、b1、b2は同じ長さとした。加えてAとB1およびB2の接続点はB1およびB2の中央とした。合わせ包みの高さDは50mm、衛生シートセットは12g/mの2枚セットとし、ポップアップ式に取り出せるように150セットの積層体を包装内に入れて評価した。取り出しやすさについては、実施例1〜12および比較例1〜9は取り出し口が直線状で一般的な仕様の比較例1を基準品とし、取り出しやすいものを○(良好)、同等以下のものを×(不良)とした。取り残しセット数は、5個の包装品の中で取り出し中に途切れて包装内に残ったセット数の一番多いものを記載した。基準品より取り出しやすく取り残しセット数の少ないものを総合評価で合格品(○)とした。表1から分かるように請求項2の条件を満たす場合はすべて総合評価で合格という結果が得られた。In Table 1 below, a film with a polyethylene material and a thickness of 50 μm is used as the film base material in the shape of the opening in FIG. 3, and the other conditions are the dimensions shown in the table. Was prepared and evaluated based on the sensitivity evaluation of ease of removal and the number of leftover sets. Further, since the shapes and lengths of the B1 and B2 parts are symmetrical and the same length is better in terms of design, b1 and b2 are set to the same length. In addition, the connection point between A and B1 and B2 is the center of B1 and B2. The height D of the combined wrapping was 50 mm, the sanitary sheet set was a set of 2 sheets of 12 g / m 2 , and 150 sets of laminates were put in the package and evaluated so that they could be taken out in a pop-up manner. Regarding the ease of taking out, Examples 1 to 12 and Comparative Examples 1 to 9 are based on Comparative Example 1 having a linear take-out port and general specifications, and those that are easy to take out are ○ (good) and equal to or less than those. Was set to × (defective). As for the number of left-over sets, the one with the largest number of sets left in the package, which was interrupted during removal, was described among the five packages. Products that are easier to take out than the standard products and have a small number of leftover sets were evaluated as acceptable products (○) in the comprehensive evaluation. As can be seen from Table 1, when the conditions of claim 2 were satisfied, the result of passing was obtained in the comprehensive evaluation.

表2では、図3の開口部形状とし表2中に記載の寸法の仕様で合わせ包みの高さDを50mm、衛生シートセットは12g/mの2枚セットとし、ポップアップ式に取り出せるように150セットの積層体を包装内に入れて評価した。表3は実施例13〜18、比較例10〜16の仕様および評価結果を示しており、比較例10を基準品として他は表1で行った評価と同様の評価を行った。表2においても請求項2の条件を満たす場合には総合評価で合格という評価が得られた。In Table 2, the opening shape shown in FIG. 3 is used, the height D of the combined wrapping is 50 mm, and the sanitary sheet set is 12 g / m 2 according to the specifications of the dimensions shown in Table 2, so that they can be taken out in a pop-up manner. 150 sets of laminates were placed in the packaging and evaluated. Table 3 shows the specifications and evaluation results of Examples 13 to 18 and Comparative Examples 10 to 16, and the same evaluation as that performed in Table 1 was performed using Comparative Example 10 as a reference product. Also in Table 2, when the condition of claim 2 was satisfied, the evaluation of passing was obtained in the comprehensive evaluation.

これらのことから、フィルム包装体から衛生シートセットをポップアップ式に取り出すときの取り出し口の形状が重要であり、横長のH字形状およびその類似形状が取り出しやすさと取り残しトラブル防止に効果があることが確認できた。取り出し口がフラップ状になっていることから衛生シートセットを取り出す時に適度に変形し抵抗が少なくなるが、衛生シートセットがコの字型の形状になりやすいため、次に取り出される衛生シートセットとの接触が適度に強くなり取り残しが無くなると考えられる。また、抵抗が大きくなり過ぎると、衛生シートセットを取り出す際に基準品と比べて違和感が大きくなる場合がある。 From these facts, the shape of the take-out port when the sanitary sheet set is taken out from the film package in a pop-up manner is important, and the horizontally long H-shape and similar shapes are effective in making it easy to take out and preventing leftover troubles. It could be confirmed. Since the take-out port is flap-shaped, it deforms moderately when taking out the sanitary sheet set and reduces resistance, but since the sanitary sheet set tends to have a U-shape, it is the same as the sanitary sheet set to be taken out next. It is considered that the contact between the two becomes moderately strong and there is no leftover. In addition, if the resistance becomes too large, the feeling of discomfort may increase when the sanitary sheet set is taken out as compared with the standard product.

表3については、表1と同じように図3の開口部形状でフィルム基材がポリエチレン素材、厚みが50μmのフィルムを使用し、その他の条件は表3に記載の寸法として衛生シートセット積層体の合わせ包み包装品を作製し、取り出しやすさの評価と取残しセット数を基に評価を実施した。またB1とB2部分の形状、長さは対称で同じ長さの方がデザイン的に良いため、b1、b2は同じ長さとした。加えてAとB1およびB2の接続点はB1およびB2の中央とした。合わせ包みの高さDは50mmとしたが、衛生シートセットは35g/mの1枚とし、ポップアップ式に取り出せるように120枚の積層体を包装内に入れて評価した。実施例19〜28および比較例17〜23は比較例17を基準品とし、取り出しやすいものを○(良好)、同等以下のものを×(不良)とした。取り残しセット数は、5個の包装品で取り出し中に途切れて包装内に残ったセット数の一番多いものを記載した。基準品より取り出しやすく取り残しセット数の少ないものを総合評価で合格品(○)とした。表3から分かるように請求項2の条件を満たす場合はすべて合格という結果が得られた。As for Table 3, the same as in Table 1, a film having an opening shape of FIG. 3, a polyethylene material as a film base material, and a thickness of 50 μm is used, and other conditions are the dimensions shown in Table 3, which are sanitary sheet set laminates. We made a combined wrapping product and evaluated it based on the ease of removal and the number of leftover sets. Further, since the shapes and lengths of the B1 and B2 parts are symmetrical and the same length is better in terms of design, b1 and b2 are set to the same length. In addition, the connection point between A and B1 and B2 is the center of B1 and B2. The height D of the combined wrapping was 50 mm, but the sanitary sheet set was one sheet of 35 g / m 2 , and 120 laminated bodies were put in the package and evaluated so that they could be taken out in a pop-up manner. In Examples 19 to 28 and Comparative Examples 17 to 23, Comparative Example 17 was used as a reference product, and those that were easy to take out were marked with ◯ (good), and those of equivalent or less were marked with x (poor). As for the number of left-over sets, the one with the largest number of sets left in the package, which was interrupted during taking out of 5 packages, was described. Products that are easier to take out than the standard products and have a small number of leftover sets were evaluated as acceptable products (○) in the comprehensive evaluation. As can be seen from Table 3, all the results were obtained as passing when the conditions of claim 2 were satisfied.

図3の開封口が基本的な形態であるが、開口部Aの部分は必ずしも一直線状でなければならないことはなく波線や矩形波状等であっても良い。また、B1、B2の開口部分も必ずしも一直線状である必要はなく、図6〜図9のような多くのバリエーションが考えられ、衛生シートセットの取り出しを阻害せず取り出し時に適度な抵抗を与えるものであれば使用可能である。B1およびB2部分の形状が直線からのずれが大きくなるに従い衛生シートセットを取り出す時の抵抗が増加する傾向にある。B1およびB2形状の直線からのずれの幅について好ましくは10mm以下、より好ましくは5mm以下である。ここでずれの幅については、(a−k)/2とした。 The opening of FIG. 3 is the basic form, but the portion of the opening A does not necessarily have to be a straight line, and may be a wavy line, a rectangular wavy shape, or the like. Further, the openings of B1 and B2 do not necessarily have to be linear, and many variations as shown in FIGS. 6 to 9 can be considered, which do not hinder the removal of the sanitary sheet set and give an appropriate resistance at the time of removal. If so, it can be used. As the shape of the B1 and B2 portions deviates from the straight line, the resistance when taking out the sanitary sheet set tends to increase. The width of deviation of the B1 and B2 shapes from the straight line is preferably 10 mm or less, more preferably 5 mm or less. Here, the width of the deviation was set to (ak) / 2.

表4では、実施形態2の評価結果を示しており、実施例5の仕様を基に実施例29〜36の仕様を作製し評価を行った。図6の開封口のB1およびB2部分のずれの幅が5mmの場合を実施例29とし、10mmの場合を実施例30として評価した。図7の開封口のB1およびB2部分のずれの幅が5mmの場合を実施例31とし、10mmの場合を実施例32として評価した。図8の開封口のB1およびB2部分のずれの幅が5mmの場合を実施例33とし、10mmの場合を実施例34として評価した。図9の開封口のB1およびB2部分のずれの幅が5mmの場合を実施例35とし、10mmの場合を実施例36とし、15mmの場合を比較例24として評価した。表4に示したようにずれの幅が10mm以下であれば良好な結果が得られた。以上の実施例としては一部の形態、形状を示したものであり、本発明がこれらに限定されるものではない。 Table 4 shows the evaluation results of the second embodiment, and the specifications of Examples 29 to 36 were prepared and evaluated based on the specifications of Example 5. The case where the width of the deviation of the B1 and B2 portions of the opening of FIG. 6 was 5 mm was evaluated as Example 29, and the case where the width was 10 mm was evaluated as Example 30. The case where the width of the deviation of the B1 and B2 portions of the opening of FIG. 7 was 5 mm was evaluated as Example 31, and the case where the width was 10 mm was evaluated as Example 32. The case where the width of the deviation of the B1 and B2 portions of the opening in FIG. 8 was 5 mm was evaluated as Example 33, and the case where the width was 10 mm was evaluated as Example 34. The case where the deviation width of the B1 and B2 portions of the opening of FIG. 9 was 5 mm was evaluated as Example 35, the case of 10 mm was evaluated as Example 36, and the case of 15 mm was evaluated as Comparative Example 24. As shown in Table 4, good results were obtained when the deviation width was 10 mm or less. The above examples show some forms and shapes, and the present invention is not limited thereto.
