Description

本発明は、生理用ナプキンに関するものである。   The present invention relates to a sanitary napkin.

この種の生理用ナプキンとしては、透液性の肌面シートと不透液性の防漏シートとの間に経血等の体液を吸収する体液吸収体が介在されたナプキン本体を有するものがある。このナプキン本体は、防漏シートの外面にショーツ等の肌着に対する止着部が粘着剤の塗布等によって設けられ、当該止着部に剥離シートが剥離可能に止着された状態で、商品として提供される。そして、特に現在では、当該剥離シートが、方形状のシートの四隅が切り欠かれた形状とされ、かつ止着状態においてナプキン本体の前後方及び両側方まで延出する大きさとされた生理用ナプキンが提案されている(例えば、特許文献1参照。)。この生理用ナプキンは、剥離シートの両側端部同士が肌面シート上において重なるように3つに折り畳まれた後、剥離シートの前後端部が加熱融着され、更にナプキン本体を横切る折り線が形成されるように例えば3つに折り畳まれて、商品として提供される。
この形態の生理用ナプキンは、非常にコンパクトなため携帯性に優れる。また、当該生理用ナプキンは、剥離シートの四隅が切り欠かれていることによって、当該剥離シートの前後端部は肌面シート上において両側端部同士が重ならずに開口が形成され、これらの開口からナプキン本体の前端部及び後端部が露出する構成とされている。したがって、この露出したナプキン本体の前端部又は後端部を摘んでナプキン本体を剥離シートから剥離することができ、装着するに容易とされている。しかしながら、この形態の生理用ナプキンは、ナプキン本体の大部分が剥離シートによって覆われており、前端部及び後端部が露出しているに過ぎないため、いずれが前端又は後端であるかが分からない。いずれかが前端又は後端であるか分からないと、ナプキン本体を剥離シートから剥離した後に、前後方向を合わせる必要が生じる場合があり、この点で装着するに不便である。また、ナプキン本体が装着の直前まで剥離シートで覆われていて衛生的であるとの長所は、当該前後合わせによって減殺される。
特許35876167号公報(図2)
This type of sanitary napkin has a napkin body in which a body fluid absorber that absorbs body fluid such as menstrual blood is interposed between a liquid-permeable skin sheet and a liquid-impervious leak-proof sheet. is there. This napkin body is provided as a product in the state where the outer surface of the leak-proof sheet is provided with a fastening part for underwear such as shorts by applying adhesive, etc., and the release sheet is fastened to the fastening part so as to be peelable Is done. In particular, at present, the release sheet has a shape in which four corners of a rectangular sheet are cut out, and the sanitary napkin has a size that extends to the front-rear side and both sides of the napkin body in the fixed state. Has been proposed (see, for example, Patent Document 1). The sanitary napkin is folded in three so that both end portions of the release sheet overlap each other on the skin sheet, and then the front and rear ends of the release sheet are heat-sealed, and a fold line across the napkin body is further formed. For example, it is folded into three so as to be formed and provided as a product.
The sanitary napkin in this form is very compact and thus has excellent portability. Further, the sanitary napkin is formed by opening the front and rear end portions of the release sheet without overlapping each other on the skin sheet by cutting off the four corners of the release sheet. The front end portion and the rear end portion of the napkin main body are exposed from the opening. Therefore, the napkin main body can be peeled from the release sheet by picking the exposed front end portion or rear end portion of the napkin main body, which is easy to attach. However, in this form of the sanitary napkin, most of the napkin main body is covered with the release sheet, and only the front end and the rear end are exposed. I do not understand. If one does not know whether it is the front end or the rear end, it may be necessary to match the front-rear direction after peeling the napkin main body from the release sheet, which is inconvenient for mounting. Further, the advantage that the napkin body is hygienic because it is covered with a release sheet until just before mounting is reduced by the front-to-back alignment.

本発明によると、ナプキン本体の大部分が剥離シートによって覆われていてもいずれが前端又は後端であるかが分かる生理用ナプキンとなる。   According to the present invention, even if the majority of the napkin main body is covered with the release sheet, the sanitary napkin can be recognized as to which is the front end or the rear end.

次に、本発明の実施の形態を説明する。
図1及び図2に示すように、本形態の生理用ナプキン10は、不繊布シートやメッシュシート等の透液性シートからなる肌面シート1とポリエチレンシート等の不透液性シートからなる防漏シート2との間に体液吸収体3が介在されたナプキン本体Xを有する。体液吸収体3は、経血等の体液を吸収する性質を有し、本形態では、コットンや積繊パルプ、高吸収性ポリマーP,P…等で構成された下側吸収コア3Bとこの下側吸収コア3Bの幅方向中央部上に積層された下側吸収コア3Bよりも幅狭の上側吸収コア3Aとがクレープ紙やティシュペーパー等からなる被覆シート3Cで額巻きされてある程度の硬性を有するコア状とされている。下側吸収コア3Bは、肌に対するフィット性や吸収力を向上させるためのものであり、省略することもできる。また、本形態においては、肌面シート1と体液吸収体3との間に不繊布等からなるセカンドシート5が積層されて、体液の拡散性向上が図られている。
Next, an embodiment of the present invention will be described.
As shown in FIGS. 1 and 2, the sanitary napkin 10 of the present embodiment includes a skin surface sheet 1 made of a liquid-permeable sheet such as a non-woven cloth sheet or a mesh sheet, and a liquid-proof sheet made of a liquid-permeable sheet such as a polyethylene sheet. It has a napkin main body X in which a body fluid absorber 3 is interposed between the leaking sheet 2. The bodily fluid absorber 3 has a property of absorbing bodily fluids such as menstrual blood, and in this embodiment, the lower absorbent core 3B composed of cotton, piled pulp, superabsorbent polymers P, P, etc. The upper absorbent core 3A, which is narrower than the lower absorbent core 3B laminated on the widthwise central portion of the side absorbent core 3B, is wound around the frame with a covering sheet 3C made of crepe paper, tissue paper, etc. It has a core shape. The lower absorbent core 3B is for improving the fit and absorbability to the skin, and can be omitted. Moreover, in this embodiment, the second sheet 5 made of a non-woven cloth or the like is laminated between the skin sheet 1 and the body fluid absorber 3 to improve the body fluid diffusibility.

肌面シート1の両側端部上には、体液の横漏れ防止機能を有する立体ギャザーRが設けられている。この立体ギャザーRは、ギャザーシート4が2つに折り重ねられて形成されており(二層構造)、折返し縁近傍のギャザーシート4間には、糸ゴム等の弾性伸縮部材Dが伸長下でホットメルト接着剤等の接着剤によって固定されている。また、肌面シート1と下層のギャザーシート4、及び、下層のギャザーシート4と上層のギャザーシート4は、それぞれホットメルト接着剤HMによって接合されており、特に前後端部においては、上層のギャザーシート4と折返し縁近傍のギャザーシート4もホットメルト接着剤HMによって接合されている。したがって、製品が舟形形状となる装着(使用)状態において、ギャザーシート4は、弾性伸縮部材Dの収縮力によって、折返し縁を先端として起立する。   A solid gather R having a function of preventing side leakage of body fluid is provided on both end portions of the skin sheet 1. This three-dimensional gather R is formed by folding two gather sheets 4 (two-layer structure), and elastic elastic members D such as rubber thread are stretched between the gather sheets 4 near the folded edge. It is fixed by an adhesive such as a hot melt adhesive. Further, the skin sheet 1 and the lower gather sheet 4, and the lower gather sheet 4 and the upper gather sheet 4 are joined together by a hot melt adhesive HM, and particularly at the front and rear end portions, the upper gather. The gather sheet 4 in the vicinity of the folded edge is also joined with the hot melt adhesive HM. Therefore, in the mounted (use) state in which the product has a boat shape, the gather sheet 4 stands up with the folded edge as the tip by the contraction force of the elastic elastic member D.

本形態において、上層のギャザーシート4は、体液吸収体3の側方に、防漏シート2と同位置まで延出して防漏シート2とでサイドフラップを構成しており、防漏シート2とでナプキン本体Xの側縁を規律している。このギャザーシート4及び防漏シート2の延出は、前後方向中央部において特に長くなっており、この長くなった部分が肌着の裏側(外面側)に折り返されて止着されるウィングWを構成している。このギャザーシート4及び防漏シート2の延出は、例えば、図5に示すように、前後方向後端部においても長くすることができ、この長くなった部分を臀部に対するフィット性や臀部からの体液の漏れ防止効果を向上させる、いわゆるエンドフラップW2とすることもできる。   In the present embodiment, the upper gather sheet 4 extends to the side of the body fluid absorber 3 to the same position as the leakage preventing sheet 2 and constitutes a side flap with the leakage preventing sheet 2. The side edge of the napkin body X is regulated. The extension of the gather sheet 4 and the leak-proof sheet 2 is particularly long in the central part in the front-rear direction, and this long part constitutes a wing W that is folded and secured to the back side (outer surface side) of the undergarment is doing. For example, as shown in FIG. 5, the gather sheet 4 and the leak-proof sheet 2 can be extended at the rear end in the front-rear direction. A so-called end flap W2 that improves the effect of preventing leakage of body fluid can also be used.

同様に、肌面シート1及び防漏シート2は、体液吸収体3よりも前後方まで延出して前後フラップを構成しており、この前後フラップの縁部がヒートシール(加熱融着)H等によって接合され、ナプキン本体Xの前後縁を規律している。   Similarly, the skin sheet 1 and the leak-proof sheet 2 extend forward and rearward from the body fluid absorber 3 to form front and rear flaps, and the edges of the front and rear flaps are heat-sealed (heat-sealed) H or the like. And the front and rear edges of the napkin body X are regulated.

一方、防漏シート2の外面には、ショーツ等の肌着に対する止着部Sが設けられている。この止着部Sは、例えば、スチレン・ブタジエン共重合体やスチレン・オレフィン共重合体等からなる粘着剤を、前後方向に帯状に塗布して形成することができる。この止着部Sは、装着時においてナプキン本体Xを肌着に止着するためのものであるが、本生理用ナプキン10を需要者に提供する段階においては、剥離シート6が止着されている。この剥離シート6は、ポリエチレンシート、ポリプロピレンシート、ポリエチレンテレフタレートシート、ラミネート紙、等からなり、止着部Sに対して剥離可能とされている。   On the other hand, the outer surface of the leak-proof sheet 2 is provided with a fastening portion S for underwear such as shorts. The fastening portion S can be formed by, for example, applying a pressure-sensitive adhesive made of a styrene / butadiene copolymer, a styrene / olefin copolymer or the like in a strip shape in the front-rear direction. The fastening portion S is for fastening the napkin body X to the underwear at the time of wearing, but the release sheet 6 is fastened at the stage of providing the sanitary napkin 10 to the consumer. . The release sheet 6 is made of a polyethylene sheet, a polypropylene sheet, a polyethylene terephthalate sheet, a laminated paper, or the like, and can be peeled from the fastening portion S.

この剥離シート6は、図1に示すように、前後端部が幅狭な形状とされ、また、ナプキン本体Xに止着されてナプキン本体Xの前後方及び両側方まで延出した状態とされている。剥離シート6の前後端部を幅狭とするための方法は、特に限定されない。図示例では、方形状のシートの四隅に切欠きKを形成して幅狭としている。この他にも、例えば、方形状のシートの前後端部の一方の側端部にのみ切欠きKを形成して、幅狭とすることもできる。   As shown in FIG. 1, the release sheet 6 has a narrow shape at the front and rear ends, and is attached to the napkin body X and extends to the front and rear and both sides of the napkin body X. ing. The method for narrowing the front and rear end portions of the release sheet 6 is not particularly limited. In the illustrated example, notches K are formed at the four corners of a square sheet to make it narrow. In addition to this, for example, the notch K can be formed only at one side end of the front and rear end portions of the rectangular sheet to narrow the sheet.

以上のような構成とされた本形態の生理用ナプキン10は、まず、図3に示すように、剥離シート6の両側端部6L,6R同士が肌面シート1上において重なるように折り畳まれ、この3つ折り状態において、剥離シート6の前後端部がヒートシール(加熱融着)Hをされる。このヒートシールHによって、剥離シート6の相互に重なった部分同士が接合されるため、折り畳んだ生理用ナプキン10が、特にナプキン本体Xの弾性力等によって意図せずに元の状態(展開状態)に戻ってしまうのが防止される。ただし、本形態では、この戻り防止効果をより確実なものとするため、図1及び図2に示すように、剥離シート6の一方の側端部6Lに粘着剤の塗布等によって粘着部Nを設けており、この粘着部Nの粘着力によって、剥離シート6の一方の側端部6Lの表面と他方の側端部6Rの外面とが止着される構成としている。   The sanitary napkin 10 of the present embodiment configured as described above is first folded so that both end portions 6L, 6R of the release sheet 6 overlap on the skin sheet 1, as shown in FIG. In the three-fold state, the front and rear end portions of the release sheet 6 are heat sealed (heat fusion) H. Since the overlapping portions of the release sheet 6 are joined to each other by the heat seal H, the folded sanitary napkin 10 is unintentionally brought into its original state (expanded state) by the elastic force of the napkin body X in particular. It is prevented that it returns to. However, in this embodiment, in order to make this return prevention effect more reliable, as shown in FIGS. 1 and 2, the adhesive portion N is applied to one side end portion 6L of the release sheet 6 by applying an adhesive or the like. The surface of one side end portion 6L of the release sheet 6 and the outer surface of the other side end portion 6R are fixed by the adhesive force of the adhesive portion N.

ところで、本形態の生理用ナプキン10は、前述したように剥離シート6の前後端部が幅狭な形状とされている。ただし、この形状は単に幅狭であれば足りるのではなく、以上の折り畳み(幅方向に関する折り畳み)を行っても、剥離シート6の前後端部は肌面シート1上において両側端部6L,6R同士が重ならず、したがって開口C1,C2が形成される幅狭形状である必要がある。しかも、この開口C1,C2の一方である前側の開口C1からはナプキン本体Xの一方の端部である前端部Xaが露出するが、開口C1,C2の他方である後側の開口C2からはナプキン本体Xの他方の端部である後端部Xbが露出しない幅狭形状である必要がある。このような幅狭形状とすることで、ナプキン本体Xの大部分が剥離シート6によって覆われていても、いずれが前端又は後端であるかが分かる生理用ナプキン10となる。しかも、ナプキン本体Xの前端部Xaを摘んでナプキン本体Xを剥離シート6から剥離することができるため、装着容易性は維持される。   By the way, as for the sanitary napkin 10 of this form, the front-and-rear end part of the peeling sheet 6 is made into the narrow shape as mentioned above. However, it is not sufficient if the shape is simply narrow. Even if the above folding (folding in the width direction) is performed, the front and rear end portions of the release sheet 6 are both end portions 6L and 6R on the skin sheet 1. Therefore, it is necessary to have a narrow shape in which the openings C1 and C2 are formed. Moreover, the front end Xa that is one end of the napkin body X is exposed from the front opening C1 that is one of the openings C1 and C2, but from the rear opening C2 that is the other of the openings C1 and C2. The napkin main body X needs to have a narrow shape that does not expose the rear end portion Xb that is the other end portion. By setting it as such a narrow shape, even if most of the napkin main body X is covered with the peeling sheet 6, it becomes the sanitary napkin 10 which can understand which is a front end or a rear end. And since the napkin main body X can be peeled from the peeling sheet 6 by pinching the front-end part Xa of the napkin main body X, mounting | wearing ease is maintained.

この際、剥離シート6を、少なくとも開口C1の周縁部6aにおいては、肌面シート1と異なる色となるようにしておけば、ナプキン本体Xの前端部Xaの視認性が向上し、装着容易性が向上する。また、開口C1は、その平均幅が、15〜30mmであるのが好ましく、20〜25mmであるのがより好ましい。開口C1の平均幅が15mm以上とされているとナプキン本体Xの前端部Xaを摘み易く、ナプキン本体Xを剥離シート6から剥離するに容易となる。   At this time, if the release sheet 6 has a color different from that of the skin sheet 1 at least at the peripheral edge 6a of the opening C1, the visibility of the front end portion Xa of the napkin body X is improved, and the ease of mounting is improved. Will improve. Moreover, it is preferable that the average width | variety of opening C1 is 15-30 mm, and it is more preferable that it is 20-25 mm. When the average width of the opening C1 is 15 mm or more, the front end portion Xa of the napkin main body X is easily picked, and the napkin main body X is easily peeled from the release sheet 6.

本形態の生理用ナプキン10においては、開口C1,C2から露出するのがナプキン本体Xの前端部Xaのみであるのか、あるいは後端部Xbのみであるのかが特に限定されない。ただし、ナプキン本体Xを摘み、ナプキン本体Xを剥離シート6から引き剥がし、肌着に装着するに至る過程を考慮すると、図示例のようにナプキン本体Xの前端部Xaのみが露出する形態が好ましい。   In the sanitary napkin 10 of this embodiment, it is not particularly limited whether only the front end portion Xa or only the rear end portion Xb of the napkin body X is exposed from the openings C1 and C2. However, in consideration of the process of picking the napkin main body X, peeling the napkin main body X from the release sheet 6 and attaching it to the underwear, a form in which only the front end portion Xa of the napkin main body X is exposed as shown in the drawing is preferable.

ここで、以上のように一方の開口C2からナプキン本体Xの後端部Xbが露出しないようにするのであれば、そもそも開口C2が形成されないよう剥離シート6の後端部は幅狭としなければよく、このように考えるのが通常である。しかしながら、本形態の生理用ナプキン10は、あえて開口C2が形成される構成とされており、この構成による効果は、次のとおりである。
すなわち、以上のように幅方向に関して折り畳まれた生理用ナプキン10は、図4に示すように、更にナプキン本体Xを横切る折り線(図3参照)が形成されるように少なくとも1回、図示例では2回折り畳まれる(前後方向に関する3つ折り)。このような折り畳みによって、本形態の生理用ナプキン10を極めてコンパクトな個別包装品とするのである。ところが、この前後方向に関する折り畳みに際して、生理用ナプキン10が開口C2を有しない構成とされていると、最も後端側の折り畳み(図4の例では、上段に示す折り畳み)を行った際に、この折り畳みによって形成される折畳み縁部分10cが厚さ方向に関して圧縮されて閉じた状態になってしまうため、この折畳み縁部分10cから後側の剥離シート6が袋状になってしまう。結果、この袋状になった剥離シート6内の空気が抜けなくなってしまい、厚さ方向に関して生理用ナプキンがコンパクトにならない。これに対し、本形態のように生理用ナプキン10が開口C2を有する構成とされていると、袋状になった剥離シート6内の空気は、当該開口C2から抜けるため、厚さ方向に関しても生理用ナプキン10が極めてコンパクトになる。このように剥離シート6内の空気が抜けるようにするという観点からは、開口C2の面積を0.09〜9cm2とするのが好ましく、1〜4cm2とするのがより好ましい。同様の観点から、開口C2の平均幅は、3〜30mmとするのが好ましく、10〜20mmとするのがより好ましい。
Here, if the rear end portion Xb of the napkin body X is not exposed from the one opening C2 as described above, the rear end portion of the release sheet 6 must be narrow so that the opening C2 is not formed in the first place. It is normal to think this way. However, the sanitary napkin 10 according to the present embodiment is configured so that the opening C2 is formed, and the effects of this configuration are as follows.
That is, the sanitary napkin 10 folded in the width direction as described above, as shown in FIG. 4, is further illustrated at least once so that a fold line (see FIG. 3) across the napkin main body X is formed. Then it is folded twice (trifold in the front-rear direction). By such folding, the sanitary napkin 10 of this embodiment is made into an extremely compact individual package. However, when the sanitary napkin 10 is configured not to have the opening C2 in the folding in the front-rear direction, when the most rear end side folding (folding shown in the upper stage in the example of FIG. 4) is performed, Since the folding edge portion 10c formed by this folding is compressed and closed in the thickness direction, the release sheet 6 on the rear side from the folding edge portion 10c becomes a bag shape. As a result, the air in the bag-like release sheet 6 cannot be removed, and the sanitary napkin is not compact in the thickness direction. On the other hand, when the sanitary napkin 10 is configured to have the opening C2 as in the present embodiment, the air in the bag-like release sheet 6 escapes from the opening C2, so that the thickness direction also applies. The sanitary napkin 10 becomes extremely compact. From the viewpoint of such such air release sheet 6 comes out to is preferably the area of the opening C2 and 0.09~9Cm 2, and more preferably, 1 to 4 cm 2. From the same viewpoint, the average width of the opening C2 is preferably 3 to 30 mm, and more preferably 10 to 20 mm.

このような前後方向に関する折り畳みによってコンパクトになった生理用ナプキン10は、先端部10aの外面に設けられた粘着テープ等の止着テープ11を、図4の下段に示すように、折畳み縁部分10cに止着させることで、折り畳んだ生理用ナプキン10が、特にナプキン本体Xの弾性力等によって元の状態(展開状態)に戻ってしまうのが防止される。この止着テープ11による止着は、剥離可能になる構成であっても、剥離不能になる構成であってもよい。剥離不能になる構成とした場合は、使用(装着)時に止着テープ11の止着箇所で剥離シート6を引きちぎって止着を解除する。   The sanitary napkin 10 that is compacted by folding in the front-rear direction has a folding edge portion 10c, as shown in the lower part of FIG. 4, of a fastening tape 11 such as an adhesive tape provided on the outer surface of the tip portion 10a. The sanitary napkin 10 that has been folded is prevented from returning to its original state (deployed state) due to the elastic force of the napkin body X in particular. The fastening with the fastening tape 11 may be configured to be peelable or may not be peelable. When it is set as the structure which cannot be peeled, the peeling sheet 6 is torn off at the fastening location of the fastening tape 11 at the time of use (mounting | wearing), and fastening is cancelled | released.

本形態の生理用ナプキン10を装着(使用)するに際しては、折り畳まれている生理用ナプキン10の先端部10a又は折畳み縁部分10cから止着テープ11を引き剥がすか、引きちぎるかし、生理用ナプキン10を前後方向に展開する。この展開によって、図3に示すような、生理用ナプキン10が幅方向に関して3つに折り畳まれた状態に戻る(三層構造)。この時、剥離シート6の前後端部は、前述したように、ヒートシールHをされて接合されているため、ナプキン本体Xの弾性力等によってこの三層構造の状態が展開されて(展開状態)、肌面シート1が露出してしまうおそれがない。したがって、極めて衛生的である。   When the sanitary napkin 10 of this embodiment is attached (used), the fastening tape 11 is peeled off or torn off from the distal end portion 10a or the folded edge portion 10c of the sanitary napkin 10 being folded, and the sanitary napkin 10 is expanded in the front-rear direction. As a result of this development, the sanitary napkin 10 returns to a state where it is folded into three in the width direction as shown in FIG. 3 (three-layer structure). At this time, since the front and rear end portions of the release sheet 6 are joined by heat sealing H as described above, the state of this three-layer structure is developed by the elastic force of the napkin body X (expanded state). ), The skin sheet 1 is not likely to be exposed. It is therefore very hygienic.

次に、剥離シート6からナプキン本体Xを剥離する。この剥離は、例えば、一方の手の指で剥離シート6の先端部を摘み、他方の手の指で開口C1から露出するナプキン本体Xの先端部Xaを摘み、この先端部Xaを手前側に引っ張ることによって、行うことができる。   Next, the napkin main body X is peeled from the release sheet 6. For this peeling, for example, the tip of the release sheet 6 is picked with the fingers of one hand, the tip Xa of the napkin body X exposed from the opening C1 is picked with the fingers of the other hand, and the tip Xa is brought to the near side. This can be done by pulling.

〔その他〕
(1)本形態の生理用ナプキン10は、ナプキン本体の平面形状が特に限定されず、例えば、前述したように前後方向に関して対称なナプキン本体Xであっても、図5に示すような、エンドフラップW2を有して前後方向に関して非対称なナプキン本体X2であってもよい。
(2)本形態の生理用ナプキン10は、ナプキン本体Xを横切る折り線が形成され折り畳み(前後方向に関する折り畳み)が何回行われるかが特に限定されない。例えば、折畳み回数が少なく最も後端側の折畳み縁部分10c(図4参照)から後側の剥離シート6が長い場合の方が本形態による効果がより発揮されるが、折畳み回数が多く最も後端側の折畳み縁部分10cから後側の剥離シート6が短い場合も本形態による効果は発揮される。また、この前後方向に関する折り畳みには、図6に示すように、1回の折畳み作業によって、ナプキン本体Xを横切る折り線が2本形成される形態(1回の折畳み作業によって2つの折畳み縁部分10d1,10d2が形成される。)も含まれる。
(3)本形態の生理用ナプキン10は、例えば、図5に示すように、帯状の剥離シート6X上に、複数のナプキン本体X2,X2…を前後方向に離間させて配置固定し、相互に前後するナプキン本体X2,X2間部分において帯状の剥離シート6Xを切断することによって、製造することができる。また、この切断に先立って、切断部分の両側端部を、切断線を跨るように連続的に切り欠いておけば、剥離シート6の前後端部が同時に幅狭となり製造効率が向上する。

The napkin main body X2 having the flap W2 and asymmetric with respect to the front-rear direction may be used.
(2) The sanitary napkin 10 of the present embodiment is not particularly limited as to how many times folding (folding in the front-rear direction) is performed by forming a fold line across the napkin body X. For example, the effect of this embodiment is more effective when the number of folding is small and the rear peeling sheet 6 is longer than the folding edge portion 10c (see FIG. 4) on the rear end side. The effect of this embodiment is also exhibited when the rear release sheet 6 is short from the end folding edge portion 10c.
