Description

本発明は、吸収性物品が包装シートによって個装された個装吸収性物品に関する。   The present invention relates to an individual absorbent article in which the absorbent article is individually packaged by a packaging sheet.

従来より、生理用ナプキン、パンティライナー、おりものシート、失禁パッドなどの吸収性物品50としては、例えば図15に示されるように、ポリエチレンシートまたはポリエチレンラミネート不織布などからなる不透液性の裏面シート51と、不織布または透孔性プラスチックシートなどからなる透液性の表面シート52との間に綿状パルプなどからなる吸収体53が介在された本体部分の両側部に夫々、装着時に下着のクロッチ部分を巻き込むようにして固定されるウイング状フラップ54、54が形成されたものが知られている。   Conventionally, as an absorbent article 50 such as a sanitary napkin, a panty liner, a cage sheet, an incontinence pad, etc., as shown in FIG. 15, for example, a liquid-impermeable back sheet made of a polyethylene sheet or a polyethylene laminated nonwoven fabric, etc. 51 and a crotch of underwear at the time of wearing, respectively, on both sides of the main body part in which an absorbent body 53 made of cotton-like pulp is interposed between a non-woven fabric or a liquid-permeable surface sheet 52 made of a porous plastic sheet or the like There is known one in which wing-shaped flaps 54 and 54 that are fixed so as to be wound around are formed.

この種の吸収性物品50では、装着状態時にズレ止めを図るために、例えば前記本体部分の非肌当接面側(裏面シート51の外面)に1または複数条の粘着剤層56…が形成されるとともに、前記ウイング状フラップ54、54の裏面シート51側の面(外面)に粘着剤層57、57が設けらている。   In this type of absorbent article 50, in order to prevent misalignment in the mounted state, for example, one or a plurality of adhesive layers 56 are formed on the non-skin contact surface side (outer surface of the back sheet 51) of the main body portion. In addition, pressure-sensitive adhesive layers 57 and 57 are provided on the surface (outer surface) of the wing-shaped flaps 54 and 54 on the back sheet 51 side.

前記吸収性物品50を下着30に固定する際には、図16に示されるように、吸収性物品50を局所にあてがい、側方に突出する前記ウイング状フラップ54、54を下着より取り出し、両ウイング状フラップ54、54を折返し線RL、RLで折返し、下着のクロッチ部分を巻き込むようにしながら前記ウイングズレ止め粘着剤層57、57を下着30の股間部外面に接着するようにする。   When fixing the absorbent article 50 to the undergarment 30, as shown in FIG. 16, the absorbent article 50 is locally applied, and the wing-shaped flaps 54, 54 projecting sideways are taken out from the underwear, The wing-shaped flaps 54, 54 are folded at folding lines RL, RL so that the wings-stopping adhesive layers 57, 57 are adhered to the crotch outer surface of the underwear 30 while the crotch portion of the underwear is wound around.

一方、前記吸収性物品50を個装するに際しては、前記ウイング状フラップ54、54を本体部分の肌当接面側(表面シート52側)に腹折りした上で、前記粘着剤層57、57を紙又はフィルムからなる剥離紙によって被覆するとともに、前記粘着剤層56…を剥離紙によって被覆し、吸収性物品50の外面側に包装シートを配置して、ナプキン50、剥離紙及び包装シートを共に長手方向に複数折りとし、側縁部分をヒートシールするとともに、開封部をタグテープ等により止着するようにしている。   On the other hand, when the absorbent article 50 is individually packaged, the wing-shaped flaps 54, 54 are folded on the skin contact surface side (surface sheet 52 side) of the main body portion, and then the pressure-sensitive adhesive layers 57, 57. Is covered with a release paper made of paper or film, the adhesive layer 56 is covered with a release paper, a packaging sheet is disposed on the outer surface side of the absorbent article 50, and the napkin 50, the release paper and the packaging sheet are disposed. Both are folded in the longitudinal direction, the side edges are heat-sealed, and the opening is fixed with a tag tape or the like.

ここで、長手方向に複数折りするに際しては、下記特許文献1に示されるように、従来より、吸収性物品の前側と後側の2箇所の折り線位置にて、吸収性物品の後側部分を表面シート側の面に折り返した後、その上に前側部分を折り返して重ねた三つ折りが主流となっている。   Here, when folding in the longitudinal direction, as shown in Patent Document 1 below, the rear part of the absorbent article is conventionally located at two fold line positions on the front side and the rear side of the absorbent article. Is folded into a surface on the surface sheet side, and then a tri-fold in which the front side portion is folded and overlapped thereon is the mainstream.

また、下記特許文献2では、吸収性物品をコンパクトに個装するため、吸収性物品が包装材の幅狭部と共に吸収性物品の長手方向に一体的に巻回されてロール状物とされた吸収性物品の包装構造が開示されている。   Moreover, in the following patent document 2, in order to package the absorbent article in a compact manner, the absorbent article is integrally wound in the longitudinal direction of the absorbent article together with the narrow portion of the packaging material to form a roll-like product. A packaging structure for absorbent articles is disclosed.

特開2003−88548号公報JP 2003-88548 A 特開2006−320397号公報JP 2006-320397 A

しかしながら、三つ折りの個装吸収性物品の場合、開封手順は、(1)タグテープを剥がし、吸収性物品の前側部分を展開する、(2)吸収性物品の後側部分を展開する、(3)吸収性物品を剥離紙及び包装シートから取り外す、という3ステップを要するため、迅速な装着というのは不可能であった。また、吸収性物品の前側部分及び後側部分の展開において、一々個装吸収性物品を持ち替える手間があり、開封作業が面倒であった。   However, in the case of a tri-fold individual absorbent article, the opening procedure is (1) peeling off the tag tape and developing the front part of the absorbent article, (2) developing the rear part of the absorbent article, 3) Since the three steps of removing the absorbent article from the release paper and the packaging sheet are required, it was impossible to mount the absorbent article quickly. Moreover, in the expansion | deployment of the front side part and rear side part of an absorbent article, there existed the effort which changes an individual absorbent article one by one, and the opening operation | work was troublesome.

また、吸収性物品の交換時に、個装吸収性物品を手の平などに隠して持ち運べるようにすることが望まれていたが、三つ折りの場合には手の平に隠れる程度にコンパクトにすることが難しかった。   In addition, when replacing absorbent articles, it was desired to be able to carry the individual absorbent articles while hiding them in the palm of the hand, but in the case of tri-fold, it was difficult to make them compact enough to be hidden in the palm. .

さらに、開封後の吸収性物品は、三つ折りの場合、図17に示されるように、折り線位置が2箇所のため、吸収性物品の前後両端部の折り角度が鋭く、折り癖によって両端部が内側に傾斜した状態となる。また、上記特許文献2のように吸収性物品を長手方向に巻回してロール状物とした場合、コンパクトな個装は実現できるものの、特にロール内側部分、すなわち吸収性物品の長手方向端部において、巻き癖によって端部が内側に湾曲した状態となる。そのため、このような吸収性物品を下着に装着しようとしても、装着作業時に吸収性物品と下着との接着が剥離しやすく長手方向端部が下着から浮き上がったり、装着中に吸収性物品が身体にフィットし難くくヨレやズレの原因となったりしていた。   Furthermore, when the absorbent article after opening is tri-folded, as shown in FIG. 17, there are two folding line positions, the folding angle of the front and rear ends of the absorbent article is sharp, Is inclined inward. In addition, when the absorbent article is wound in the longitudinal direction as in Patent Document 2 to form a roll, a compact individual packaging can be realized, but particularly at the inner part of the roll, that is, the longitudinal end of the absorbent article. The end portion is bent inward by the curl. For this reason, even if such an absorbent article is to be attached to the undergarment, the adhesive article and the undergarment are easily peeled off during the wearing operation, and the longitudinal end portion is lifted from the undergarment. It was difficult to fit and could cause kinks and misalignments.

そこで本発明の主たる課題は、迅速かつ容易な開封を可能にするとともに、コンパクトな個装形状とし、開封後の吸収性物品の装着作業を容易にするとともに、身体にフィットしやすくした個装吸収性物品を提供することにある。   Therefore, the main problem of the present invention is to enable quick and easy opening, as well as to make a compact individual packaging shape, to facilitate the mounting work of the absorbent article after opening, and to easily fit the body. It is to provide a sex article.

前記課題を解決するために請求項1に係る本発明として、透液性表面シートと裏面シートとの間に吸収体が介在された吸収性物品と、この吸収性物品を個装する包装シートとからなり、前記吸収性物品は、長手方向の両端部をそれぞれ前記表面シート側の面に折り畳むとともに、更に略長手方向中心部にて内側に折り畳むことにより四つ折りとされた個装吸収性物品であって、
前記包装シートは、前記吸収性物品の長手方向一方側の端部から外側に延在して設けられ、前記吸収性物品の両端折り畳み部を折り畳んだ状態で、前記吸収性物品を長手方向に沿って包囲し、次いで前記吸収性物品と共に四つ折りに折り畳まれた後、前記包装シートの開口した両側縁部が封鎖されるとともに、外側延在部分の端部が開封端部として前記包装シートの外面に剥離可能に接合されて個装状態とされ、
使用時に、前記開封端部を摘んで展開方向に引っ張ることにより、前記包装シートと吸収性物品の折り畳みが展開できるようにしたことを特徴とする個装吸収性物品が提供される。
In order to solve the above-mentioned problem, as the present invention according to claim 1, an absorbent article in which an absorbent body is interposed between a liquid-permeable top sheet and a back sheet, and a packaging sheet for individually packaging the absorbent article, The absorbent article is an individual absorbent article that is folded into four parts by folding both ends in the longitudinal direction to the surface on the surface sheet side, and further folding inward at a substantially central part in the longitudinal direction. There,
The packaging sheet is provided to extend outward from an end portion on one side in the longitudinal direction of the absorbent article, and the absorbent article is laid along the longitudinal direction in a state where both end folding portions of the absorbent article are folded. And then folded into four folds together with the absorbent article, and then both open side edges of the packaging sheet are sealed, and the end of the outer extending portion serves as an open end, and the outer surface of the packaging sheet To be separated and separated into individual states,
In use, the individual absorbent article is characterized in that the folded end of the packaging sheet and the absorbent article can be unfolded by picking the opening end and pulling in the unfolding direction.

上記請求項1記載の発明では、個装状態において、吸収性物品は、長手方向の両端部をそれぞれ前記表面シート側の面に折り畳むとともに、更に略長手方向中心部にて内側に折り畳むことにより四つ折りとされているため、コンパクトな個装吸収性物品とすることができ、吸収性物品の交換時に個装吸収性物品を手の平などに隠して持ち運ぶことができるようになる。   In the first aspect of the present invention, in the individually packaged state, the absorbent article is folded by folding both ends in the longitudinal direction to the surface on the surface sheet side, and further folding inwardly at the substantially longitudinal center. Since it is folded, it can be set as a compact individual absorbent article, and when replacing the absorbent article, the individual absorbent article can be concealed in the palm or the like and carried.

And then folded into four folds together with the absorbent article, and then both side edges of the opening of the packaging sheet are sealed, and the end portion of the outer extending portion is used as the opening end portion. It is joined to the outer surface of the detachable state in an individual state. And at the time of use of the individual absorbent article, the folding end of the packaging sheet and the absorbent article can be unfolded by picking the opening end and pulling it in the unfolding direction. Therefore, the unpacking procedure consists of two steps: (1) picking the unsealed end and pulling it in the unfolding direction; and (2) removing the absorbent article from the packaging sheet. As described above, it is possible to mount quickly without requiring 3 steps for opening. Moreover, since folding of an absorbent article can be expand | deployed only by pulling an opening edge part to an expansion | deployment direction, it is not necessary to carry out the individual absorbent article one by one, and opening operation becomes easy.

さらに、前述の通り四つ折りであるため、3箇所の折り位置で緩やかに折れ曲がり、折り癖による吸収性物品の傾斜が、長手方向に対して外側に広がった形状となる。このため、かかる吸収性物品を下着に装着する際、下着の湾曲に沿いやすく、下着と接合し易くなるとともに、身体にもフィットしやすく、装着中のヨレやズレが防止できる。   Furthermore, as described above, since it is a quadruple fold, it bends gently at the three fold positions, and the inclination of the absorbent article due to the crease spreads outward in the longitudinal direction. For this reason, when attaching such an absorbent article to the underwear, it is easy to follow the curvature of the underwear, to be easily joined to the underwear, and to be easily fitted to the body, thereby preventing twisting and displacement during wearing.

[Structural example of sanitary napkin 1]
The sanitary napkin 1 according to the present invention includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, etc., a liquid-permeable top sheet 3 that allows rapid passage of menstrual blood, vaginal discharge, and the like. It is comprised from the absorber 4 which consists of cotton-like pulp or synthetic | combination pulp interposed between the sheets 2 and 3, and the side nonwoven fabric 6 formed in the surface side both sides along the longitudinal direction, respectively. The side edges in the longitudinal direction of the main body part in which the absorbent body 4 is interposed between the top sheet 3 and the back sheet 2, respectively, protrude sideways by the bonded portion of the back sheet 2 and the side nonwoven fabric 6, respectively. A flap portion where the absorbent body 4 is not interposed is formed, and the flap portion includes wing-like flaps W and W which are fixed so as to entrain the crotch portion of the underwear when being worn. The absorbent body 4 can be surrounded by crepe paper for shape retention and diffusibility improvement.

また、前記表面シート3と裏面シート2との間に吸収体4が介在された本体部分の裏面には、下着に対する固定のために適宜の塗布パターンによって複数条の、図示例では2条の本体ズレ止め粘着剤層7,7…が形成されている。また、前記ウイング状フラップW、Wの裏面シート2側の面(裏面)には、ウイングズレ止め粘着剤層8、8が形成されている。さらに、ナプキン1の後側端部近傍の裏面シート2側の面(裏面)には、展開用粘着剤層9が形成されている。   In addition, the back surface of the main body portion in which the absorbent body 4 is interposed between the top sheet 3 and the back sheet 2 has a plurality of strips in the illustrated example, and two strips in the illustrated example, for fixing to the underwear. Displacement prevention adhesive layers 7, 7,... Are formed. Moreover, the wings prevention adhesive layer 8 and 8 is formed in the surface (back surface) by the side of the back sheet 2 of the said wing-shaped flaps W and W. As shown in FIG. Further, a developing pressure-sensitive adhesive layer 9 is formed on the surface (back surface) on the back sheet 2 side in the vicinity of the rear end portion of the napkin 1.

以下、さらに前記生理用ナプキン1の構造例について詳述すると、
前記裏面シート2は、ポリエチレンやポリプロピレン等のオレフィン系樹脂シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには防水フィルムを介在して実質的に不透液性を確保した上で不織布シート(この場合には防水フィルムと不織布とで不透液性裏面シートを構成する。)などを用いることができる。近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材は、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートである。
Hereinafter, the structural example of the sanitary napkin 1 will be described in detail.
The back sheet 2 is made of a sheet material having at least a water shielding property such as an olefin resin sheet such as polyethylene or polypropylene. In addition to this, a laminated nonwoven fabric in which a nonwoven fabric is laminated on a polyethylene sheet or the like, and further a waterproof film is interposed. Then, after substantially ensuring liquid impermeability, a nonwoven fabric sheet (in this case, a waterproof film and a nonwoven fabric constitute a liquid impervious back sheet) and the like can be used. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. This water- and moisture-permeable sheet material is a microporous sheet obtained by forming a sheet by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching in a uniaxial or biaxial direction. It is.

次いで、前記表面シート3は、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維としては、たとえばポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高でソフトである点で優れている。   Next, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used as the top sheet 3. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft.

前記裏面シート2と表面シート3との間に介在される吸収体4は、たとえばフラッフ状パルプと吸水性ポリマーとにより構成されている。前記吸水性ポリマーは吸収体を構成するパルプ中に、例えば粒状粉として混入されている。前記パルプとしては、木材から得られる化学パルプ、溶解パルプ等のセルロース繊維や、レーヨン、アセテート等の人工セルロース繊維からなるものが挙げられ、広葉樹パルプよりは繊維長の長い針葉樹パルプの方が機能および価格の面で好適に使用される。本例のように、吸収体4を囲繞するクレープ紙を設ける場合には、結果的に透液性表面シート3と吸収体4との間にクレープ紙が介在することになり、吸収性に優れる前記クレープ紙によって体液を速やかに拡散させるとともに、これら経血等の逆戻りを防止するようになる。   The absorber 4 interposed between the said back surface sheet 2 and the surface sheet 3 is comprised by the fluffy pulp and the water absorbing polymer, for example. The water-absorbing polymer is mixed in the pulp constituting the absorber, for example, as granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolved pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length than hardwood pulp functions and It is preferably used in terms of price. When the crepe paper surrounding the absorber 4 is provided as in this example, the crepe paper intervenes between the liquid-permeable surface sheet 3 and the absorber 4 as a result, and the absorbency is excellent. The crepe paper quickly diffuses body fluid and prevents reversal of these menstrual blood and the like.

また、前記吸収体4に合成繊維を混合しても良い。前記合成繊維は、例えばポリエチレン又はポリプロピレン等のポリオレフィン系、ポリエチレンテレフタレートやポリブチレンテレフタレート等のポリエステル系、ナイロンなどのポリアミド系、及びこれらの共重合体などを使用することができるし、これら2種を混合したものであってもよい。また、融点の高い繊維を芯とし融点の低い繊維を鞘とした芯鞘型繊維やサイドバイサイド型繊維、分割型繊維などの複合繊維も用いることができる。前記合成繊維は、体液に対する親和性を有するように、疎水性繊維の場合には親水化剤によって表面処理したものを用いるのが望ましい。   Further, synthetic fibers may be mixed in the absorbent body 4. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.

前記ズレ止め粘着剤層7、8、9を形成する粘着剤としては、たとえばスチレン系ポリマー、粘着付与剤、可塑剤のいずれかが主成分であるものが好適に使用される。前記スチレン系ポリマーとしては、スチレン−エチレン−ブチレン−スチレンブロック共重合体、スチレン−ブチレン−スチレンブロック共重合体、スチレン−イソブチレン−スチレン共重合体等が挙げられるが、これらのうち1種のみを使用しても、二種以上のポリマーブレンドであってもよい。この中でも熱安定性が良好であるという点で、スチレン−エチレン−ブチレン−スチレンブロック共重合体が好ましい。また、前記粘着付与剤および可塑剤としては、常温で固体のものを好ましく用いることができ、粘着付与剤ではたとえばC5系石油樹脂、C9系石油樹脂、ジシクロペンタジエン系石油樹脂、ロジン系石油樹脂、ポリテルペン樹脂、テルペンフェノール樹脂等が挙げられ、前記可塑剤では例えば、リン酸トリフレシル、フタル酸ジブチル、フタル酸ジオクチル等のモノマー可塑剤の他、ビニル重合体やポリエステルのようなポリマー可塑剤が挙げられる。   As the pressure-sensitive adhesive that forms the anti-displacement pressure-sensitive adhesive layers 7, 8, and 9, for example, a styrenic polymer, a tackifier, or a plasticizer whose main component is preferably used. Examples of the styrenic polymer include styrene-ethylene-butylene-styrene block copolymers, styrene-butylene-styrene block copolymers, and styrene-isobutylene-styrene copolymers. It may be used or two or more polymer blends. Among these, a styrene-ethylene-butylene-styrene block copolymer is preferable in terms of good thermal stability. As the tackifier and plasticizer, those that are solid at room temperature can be preferably used. Examples of the tackifier include C5 petroleum resins, C9 petroleum resins, dicyclopentadiene petroleum resins, and rosin petroleum resins. Polyterpene resin, terpene phenol resin, etc., and examples of the plasticizer include monomer plasticizers such as trifresil phosphate, dibutyl phthalate, dioctyl phthalate, and polymer plasticizers such as vinyl polymers and polyesters. It is done.

A paper or plastic sheet that has been coated or spray-coated and release-treated can be used. It should be noted that the film itself or the nonwoven fabric itself may be used as long as it does not cause a substantial decrease in the adhesive force without special release treatment.

さらに、前記個装生理用ナプキンNは、図1に示されるように、幅方向の仮想の折り線L1〜L5の位置にて、長手方向に折り畳まれて個装状態とされる。   Further, as shown in FIG. 1, the individually packaged sanitary napkin N is folded in the longitudinal direction at the positions of virtual fold lines L1 to L5 in the width direction to be individually packaged.

〔個装手順〕
前述した個装生理用ナプキンNを個装する手順について説明する。
[Individual packaging procedure]
A procedure for individually mounting the above-described individually packaged sanitary napkin N will be described.

先ず、図3に示されるように、本体ズレ止め粘着剤層7、7を剥離紙5によって覆う。さらに、前記ウイング状フラップW、Wをそれぞれ、表面シート3側の面(表面)に折り返すとともに、このウイング状フラップW、Wと重ならないように、ナプキン1の後端折り畳み部1Aを折り線L1位置にて表面側に折り返す。これにより、一対のウイングズレ止め粘着剤層8、8が隣接配置されるとともに、その後側に展開用粘着剤層9が配置される。これらウイングズレ止め粘着剤層8、8及び展開用粘着剤層9を一体的に剥離紙11によって剥離可能に覆う。   First, as shown in FIG. 3, the main body displacement preventing adhesive layers 7 and 7 are covered with a release paper 5. Further, the wing-shaped flaps W, W are folded back to the surface (surface) on the surface sheet 3 side, and the rear end folded portion 1A of the napkin 1 is folded at a fold line L1 so as not to overlap the wing-shaped flaps W, W. Fold back to the front side at the position. Thereby, while a pair of wings prevention adhesive layer 8 and 8 is arrange | positioned adjacently, the adhesive layer 9 for an expansion | deployment is arrange | positioned at the back side. The wings-stopping adhesive layers 8 and 8 and the developing adhesive layer 9 are integrally and releasably covered with a release paper 11.

その後、図4に示されるように、包装シート10に前記剥離紙5の非離型処理加工面側を接着し、包装シート10にナプキン1を配置する。このとき、前記折り線L1位置にて折り返した後端折り畳み部1Aの後端部と包装シート10の後側端部を合わせるように配置する。   Thereafter, as shown in FIG. 4, the non-release processing surface side of the release paper 5 is bonded to the packaging sheet 10, and the napkin 1 is disposed on the packaging sheet 10. At this time, it arrange | positions so that the rear-end part of 1 A of rear-end folding parts and the rear-end part of the packaging sheet 10 turned up in the said folding line L1 position may be match | combined.

次に、図5に示されるように、ナプキン1の前端折り畳み部1Bを折り線L3位置にて包装シート10とともに表面側に折り畳む。このとき、包装シート10は、前記外側延在部分10Aによってナプキン1を長手方向に沿って包囲し、さらにナプキン1の後端折り畳み部1Aの後端部より外側に延在する位置まで設けられる。この折り畳みと同時に、包装シート10の外側延在部分10Aに前記剥離紙11の非離型処理加工面側を接着する。この折り畳みにより、ナプキン1は、後端折り畳み部1A及び前端折り畳み部1Bがそれぞれ、表面側に折り畳まれた状態となる。なお、この折り畳みにより、折り線L2とL4とが重なるとともに、折り線L1とL4とが重なるようになる。   Next, as shown in FIG. 5, the front end folding portion 1 </ b> B of the napkin 1 is folded together with the packaging sheet 10 to the surface side at the position of the folding line L <b> 3. At this time, the packaging sheet 10 is provided up to a position that surrounds the napkin 1 along the longitudinal direction by the outer extending portion 10A, and further extends outside the rear end portion of the rear end folding portion 1A of the napkin 1. Simultaneously with this folding, the non-release processing surface side of the release paper 11 is adhered to the outer extending portion 10A of the packaging sheet 10. By this folding, the napkin 1 is in a state in which the rear end folded portion 1A and the front end folded portion 1B are folded to the front side. Note that the folding causes the folding lines L2 and L4 to overlap and the folding lines L1 and L4 to overlap.

更に、図6に示されるように、後端折り畳み部1A及び前端折り畳み部1Bを腹折りしたナプキン1の略長手方向(前後方向)中心部の折り線L2(L4)位置にて包装シート10とともに内側に折り畳む(ナプキン1の後端折り畳み部1A及び前端折り畳み部1Bを対向させるように折り畳む)。この折り畳みにより、ナプキン1は四つ折りに折り畳まれる。   Furthermore, as shown in FIG. 6, together with the packaging sheet 10 at the position of the fold line L2 (L4) in the center of the substantially longitudinal direction (front-rear direction) of the napkin 1 obtained by folding the rear end folded portion 1A and the front end folded portion 1B. Folded inward (folded so that the rear end folded portion 1A and the front end folded portion 1B of the napkin 1 face each other). By this folding, the napkin 1 is folded into four.

次いで、図7に示されるように、ナプキン1の後端折り畳み部1Aの後端部より外側に延在する包装シート10の外側延在部分10Aを、ナプキン1の後端折り畳み部1Aの後端部を巻き込むように、折り線L5(L1)位置にて折り返す。   Next, as shown in FIG. 7, the outer extended portion 10 </ b> A of the packaging sheet 10 extending outward from the rear end folded portion 1 </ b> A of the napkin 1 is used as the rear end folded portion 1 </ b> A of the napkin 1. It is folded at the position of the fold line L5 (L1) so as to wind the part.

しかる後、図8に示されるように、この折り返した端部を開封端部とし、包装シート10の外面にタブテープ15によって剥離可能に接合するとともに、包装シート10の開口した両側縁部10a、10aをエンボス圧着、加熱融着、接着剤等、適宜の封鎖手段の単独または組合せによって封鎖し、折り畳み形状を保持する。   Thereafter, as shown in FIG. 8, the folded end portion is used as an unsealed end portion, and is joined to the outer surface of the packaging sheet 10 by the tab tape 15 so as to be peelable, and both side edge portions 10 a and 10 a opened in the packaging sheet 10. Is sealed by a single or combination of suitable sealing means such as embossing, heat sealing, and adhesive, and the folded shape is maintained.

〔開封手順〕
次に、使用時に、図8に示される製品状態の個装生理用ナプキンNを開封する手順について説明する。本個装生理用ナプキンNの開封手順は、(1)図9及び図10に示されるように、タグテープ15を摘んで剥がし、そのまま展開方向に引っ張る、(2)ナプキン1を包装シート10から取り外す、という2ステップからなる。前記第1ステップにより、ナプキン1の前端折り畳み部1Bが展開するとともに後端折り畳み部1Aが展開用粘着剤層9と剥離紙11との接合により引っ張られて展開し、且つ包装シート10の側縁部分10a、10aの封鎖手段が解除されて、ナプキン1が展開する。
[Opening procedure]
Next, the procedure for opening the individually packaged sanitary napkin N shown in FIG. 8 during use will be described. The unpacking procedure of this sanitary napkin N is as follows: (1) As shown in FIG. 9 and FIG. It consists of two steps of removing. By the first step, the front end folded portion 1B of the napkin 1 is unfolded and the rear end folded portion 1A is unfolded and unfolded by joining the unfolding adhesive layer 9 and the release paper 11, and the side edge of the packaging sheet 10 The sealing means of the portions 10a and 10a are released, and the napkin 1 is developed.

これに対し、従来の三つ折りの個装吸収性物品の場合、開封手順は、上述の通り、(1)タグテープを剥がし、吸収性物品の前側部分を展開する、(2)吸収性物品の後側部分を展開する、(3)吸収性物品を剥離紙及び包装シートから剥がす、という3ステップを要する。このため、本発明に係る個装生理用ナプキンNでは、上記2ステップであるので、迅速な装着が可能となる。   On the other hand, in the case of a conventional tri-fold individual absorbent article, the opening procedure is as described above, (1) peeling off the tag tape and developing the front side part of the absorbent article, (2) the absorbent article Three steps of unfolding the rear portion and (3) peeling the absorbent article from the release paper and the packaging sheet are required. For this reason, in the individually packaged sanitary napkin N according to the present invention, since it is the above-mentioned two steps, quick mounting is possible.

また、開封後のナプキン1は、図11に示されるように、折り線位置が3箇所(折り線L1、L2、L3)であるため、ナプキン1の折り角度が小さくなり、折り癖によるナプキン1の傾斜が、長手方向に対して全体に外側に広がった形状となる。このため、このようなナプキンを下着に装着する場合、下着の湾曲に沿いやすく、本体ズレ止め粘着剤層7の接着が効果的となる。また、身体にもフィットしやすく、装着中のヨレやズレが防止できるようになる。   Moreover, since the napkin 1 after opening has three folding line positions (folding lines L1, L2, and L3) as shown in FIG. 11, the folding angle of the napkin 1 becomes small, and the napkin 1 by folding folds Is a shape that spreads outward as a whole in the longitudinal direction. For this reason, when such a napkin is attached to the undergarment, it is easy to follow the curvature of the undergarment, and the adhesion of the main body displacement prevention adhesive layer 7 becomes effective. In addition, it is easy to fit on the body, and it is possible to prevent twisting and shifting during wearing.

〔他の形態例〕
(1)上記形態例では、包装シート10は略矩形状のシートとされていたが、図12に示されるように、包装シート10の外側延在部分10Aが設けられる側に位置する前端折り畳み部1Bと前記外側延在部分10Aの端部までの区間内において、包装シート10の両側縁部に切欠き部10b、10bを形成してもよい。さらに具体的には、前記切欠き部10bは、折り線L3からL5の範囲S内の包装シート10の両側縁部に形成されることが好ましい。これにより、個装生理用ナプキンNを折り畳んで包装シート10の両側縁部10a、10aを封鎖する際に、この両側縁部10a、10aの資材枚数が低減するため、封鎖手段が容易となる。
