Description

パンツタイプ使い捨て着用物品Pants type disposable wear items
　本発明は、パンツタイプ使い捨て着用物品に関するものである。 The present invention relates to a pants-type disposable wear item.
　パンツタイプ使い捨ておむつや、パンツタイプ使い捨て生理用ナプキン、パンツタイプ使い捨ておむつカバー等のパンツタイプ使い捨て着用物品は、前身頃の両側部と後身頃の両側部とがそれぞれ接合されたサイドシールを有しており、このサイドシールの形成により、ウエスト開口及び脚開口が予め形成されたものである。 Pants-type disposable items such as pants-type disposable napkins, pants-type disposable sanitary napkins, and pants-type disposable napkin covers have side seals in which both sides of the front body and both sides of the back body are joined. The waist opening and the leg opening are formed in advance by the formation of the side seal.
　このようなパンツタイプ使い捨ておむつにおいては、排泄後などにおいておむつを脱がす際、サイドシールで前身頃と後身頃とを引き剥がし、おむつを身体から取り除くことが行われる。このため、サイドシールには、装着中に破れないような剥離強度だけでなく、使用後の剥がしやすさも求められている。 In such pants-type disposable diapers, when the diaper is taken off after excretion, the front body and the back body are peeled off with a side seal to remove the diaper from the body. For this reason, the side seal is required not only to have a peeling strength that does not tear during mounting, but also to be easy to peel off after use.
　サイドシールで前身頃と後身頃とを引き剥がしやすくするための一つの手法は、サイドシール部の接合パターンの改良であるが、接合パターンの改良だけで引きはがしやすさを改良することは困難な場合も多い。特に、サイドシールに要求される剥離強度を確保しつつ、力の弱い高齢者等でも剥離を容易にすることは困難である。 One method for making it easier to peel off the front body and the back body with the side seal is to improve the joining pattern of the side seal part, but it is difficult to improve the ease of peeling only by improving the joining pattern. In many cases. In particular, it is difficult to facilitate peeling even for elderly people with weak strength while ensuring the peeling strength required for the side seal.
　この問題を解決する一つの手法として、サイドシールの接合パターンを改良するのではなく、前身頃又は後身頃におけるサイドシールよりも幅方向中央側に、ウエスト開口から脚開口にかけてミシン目を形成することも提案されている（例えば特許文献１、２参照）。この場合、サイドシールの剥離強度に影響されることなく、前身頃及び後身頃の分離が容易となる。 One method to solve this problem is to form a perforation from the waist opening to the leg opening on the center side in the width direction of the front body or the back body rather than improving the joining pattern of the side seals. Has also been proposed (see, for example, Patent Documents 1 and 2). In this case, the front body and the back body can be easily separated without being affected by the peeling strength of the side seal.
　しかしながら、前身頃又は後身頃に単にミシン目を設けるだけでは、ミシン目を切り離す途中で、幅方向中央側に向かって引き裂いてしまう「横裂け」が発生するおそれがある。 However, simply providing perforations on the front or back body may cause "lateral tears" that tear toward the center in the width direction while the perforations are being separated.

　そこで、本発明の主たる課題は、前身頃及び後身頃の分離をミシン目により弱い力で行うことができるものでありながら、横裂けを発生しにくくすることにある。 Therefore, the main object of the present invention is to make it difficult for lateral tears to occur while being able to separate the front body and the back body with a weaker force at the perforations.
　上記課題を解決したパンツタイプ使い捨て着用物品は以下のとおりである。
　＜第１の形態＞
　　前身頃及び後身頃と、
　前身頃の両側部と後身頃の両側部とがそれぞれ接合されて形成されたサイドシールと、

　胴周り部のウエスト側の開口であるウエスト開口と、
　胴周り部よりも脚側に形成された、左右一対の脚開口と、を備え、
　前身頃及び後身頃の少なくとも一方におけるサイドシールよりも幅方向中央側に、ウエスト開口から脚開口にかけてミシン目が形成され、
　前記ミシン目は、縦方向に延びる第１ミシン目と、この第１ミシン目端から前記サイドシール側に斜めに延びる第２ミシン目とを有する単位が、縦方向に繰り返し設けられ、

　ことを特徴とするパンツタイプ使い捨て着用物品。 The pants-type disposable wear items that have solved the above problems are as follows.
<First form>
Front body and back body,
Side seals formed by joining both sides of the front body and both sides of the back body,
Around the waist, which is continuous in a tubular shape via a side seal,
The waist opening, which is the waist opening around the waist,
It has a pair of left and right leg openings formed on the leg side of the waistline.
A perforation is formed from the waist opening to the leg opening on the center side in the width direction with respect to the side seal on at least one of the front body and the back body.
In the perforation, a unit having a first perforation extending in the vertical direction and a second perforation extending diagonally from the end of the first perforation to the side seal side is repeatedly provided in the vertical direction.
The second perforation is an upward second perforation extending diagonally upward, and

Pants-type disposable wear items that are characterized by this.
（作用効果）
　前記ウエスト開口から前記脚開口に向けて、上から下へ、又は、下から上へと、前記ミシン目を連続して切り離しやすく、切り離し途中で前身頃と後身頃の横裂けを発生しにくくし、前記パンツタイプ使い捨て着用物品を着用者から容易に外すことができる。
　前身頃、後身頃のサイドシールに沿って前記ミシン目があるため、どこからでも切り離すことが可能であり、１か所ずつ切ることも可能である。
　前記第１ミシン目端と、前記サイドシール側に斜めに延びる第２ミシン目始点は、繋がっていることが好ましく、前記第１ミシン目と前記第２ミシン目が一連となっていることで、切り離しが前記第１ミシン目から前記第２ミシン目へと連続して起きる。
　また、前記サイドシールが前記第２ミシン目延長線上にあるため、万一前記第２ミシン目端部における切り離しが前記第１ミシン目に戻らなかった場合でも、前記サイドシールに沿って脚開口へ切り離しが進む。
　本形態は、横裂けが起こりにくい最低限の形態である。 (Action effect)
From the waist opening to the leg opening, it is easy to continuously separate the perforations from top to bottom or from bottom to top, and it is difficult for lateral tearing of the front body and the back body to occur during the separation. , The pants-type disposable wearable article can be easily removed from the wearer.
Since the perforations are located along the side seals of the front and back bodies, they can be separated from anywhere and can be cut one by one.
The end of the first perforation and the start point of the second perforation that extends diagonally to the side seal side are preferably connected, and the first perforation and the second perforation are in a series. Separation occurs continuously from the first perforation to the second perforation.
Further, since the side seal is on the extension line of the second perforation, even if the disconnection at the end of the second perforation does not return to the first perforation, the leg opening is reached along the side seal. Separation proceeds.
This form is the minimum form in which lateral tearing is unlikely to occur.

（作用効果）
　　前記単位に存在するミシン目の前記第２ミシン目から、縦方向に連続する次の単位のミシン目始点へ、分離する力が前記折り返しにより誘導されるため、連続したミシン目の切り離しが可能で、切り離し途中で前身頃と後身頃の横裂けが発生しにくく、前記パンツタイプ使い捨て着用物品を着用者から容易に外すことができる。
　前記折り返しがあることにより、前記第２ミシン目で生じている力が、前記第１ミシン目がある縦方向へ半ば強制的に戻るため、前記第１の形態に比べ縦方向への切り離しが前記第２ミシン目を通して円滑に進む。 (Action effect)
Since the force for separating from the second perforation of the perforation existing in the unit to the perforation start point of the next unit continuously in the vertical direction is induced by the folding back, continuous perforation can be separated. Lateral tearing of the front body and the back body is unlikely to occur during the separation, and the pants-type disposable worn item can be easily removed from the wearer.
Due to the folding back, the force generated at the second perforation is forcibly returned halfway in the vertical direction in which the first perforation is located. Proceed smoothly through the second perforation.
＜第３の形態＞
　縦方向に繰り返し並ぶ前記ミシン目の単位間で、前記上方向第２ミシン目端が逆方向上側に折り返して延在する、前記ミシン目端を有する、

（作用効果）
　前記単位に存在するミシン目の前記第２ミシン目から、縦方向に連続する次の単位のミシン目始点へ、分離する力が前記折り返しにより誘導されるため、連続したミシン目の切り離しが可能で、切り離し途中で前身頃と後身頃の横裂けが発生しにくく、前記パンツタイプ使い捨て着用物品を着用者から容易に外すことができる。
　前記折り返しがあることにより、前記第２ミシン目で生じている力が、前記第１ミシン目がある縦方向へ半ば強制的に戻るため、前記第１の形態に比べ縦方向への切り離しが前記第２ミシン目を通じて円滑に進む。
　前記第２の形態では、縦方向上から下へ切り離しが進むが、本形態では、下から上へと切り離しが進む。 (Action effect)
Since the force for separating from the second perforation of the perforation existing in the unit to the perforation start point of the next unit continuously in the vertical direction is induced by the folding back, continuous perforation can be separated. Lateral tearing of the front body and the back body is unlikely to occur during the separation, and the pants-type disposable worn item can be easily removed from the wearer.
Due to the folding back, the force generated at the second perforation is forcibly returned halfway in the vertical direction in which the first perforation is located. Proceed smoothly through the second perforation.
In the second mode, the separation proceeds from the top to the bottom in the vertical direction, but in the present embodiment, the separation proceeds from the bottom to the top.
＜第４の形態＞
　縦方向に繰り返し並ぶ前記ミシン目の単位間で、前記下方向第２ミシン目端が逆方向下側に折り返した延長線上に前記第１ミシン目を有し、

　前記下方向第２ミシン目の折り返し延長線上に次の前記単位の前記第１ミシン目が存在し、前記上方向第２ミシン目の延長線上に前の前記単位の前記下方向第２ミシン目が、配置されている。本形態は、前記第１と第２の形態の組み合わせで、前記単位間距離が狭く、前記単位の始点及び終点が近位にあるため、単位ミシン目間の誘導が生じやすくなり、切り離しがミシン目に沿って起こりやすくなる。
　また、切り離しの方向は、前記ウエスト開口から前記脚開口へ上から下へでも、又は、その逆の下から上へでも、いずれからも切り離すことが可能である。 (Action effect)
The first perforation of the next unit is present on the folded extension line of the lower second perforation, and the lower second perforation of the previous unit is on the extension line of the upper second perforation. , Have been placed. This form is a combination of the first and second forms. Since the distance between the units is narrow and the start point and the end point of the unit are proximal to each other, guidance between unit perforations is likely to occur, and the sewing machine can be separated. It is more likely to occur along the eyes.
Further, the direction of separation can be either from top to bottom from the waist opening to the leg opening, or vice versa.

　前記第１ミシン目の孔がない部分に補助ミシン目の孔を配置することで、前記弾性部材が切断されている箇所を作り、確実に切り離しを進めることが出来る。
　万一、前記ミシン目から幅方向中央側に横裂けが生じた場合でも、補助ミシン目から縦方向の切り離しを再開できる。 (Action effect)
During the separation of the perforations on the front body or the back body, the elastic member existing in the width direction of the front body or the back body may stop the continuous separation of the perforations or cause lateral tearing. The pants-type disposable wearable article can be easily removed from the wearer.
By arranging the holes in the auxiliary perforations in the portions where the holes in the first perforations are not provided, it is possible to create a portion where the elastic member is cut and to proceed with the separation reliably.
Even if a lateral tear occurs from the perforation to the center side in the width direction, the vertical separation from the auxiliary perforation can be resumed.
＜第６の形態＞
　前記第２ミシン目の延長線上に、前記第２ミシン目の端部を囲むように、U字型の孔を有する、

　以下、吸収性物品の一例としてのパンツタイプ使い捨ておむつについて、添付図面を参照しつつ詳説する。 Below, a pants-type disposable diaper as an example of an absorbent article will be described in detail with reference to the attached drawings.
　図１～図６はパンツタイプ使い捨ておむつを示している。このパンツタイプ使い捨ておむつ（以下、単におむつともいう。）は、前身頃Ｆ及び後身頃Ｂにわたる外装体２０と、前身頃Ｆから後身頃Ｂにわたるように外装体２０の内面に固定された内装体１０とを有しており、内装体１０は液透過性のトップシート１１と液不透過性シート１２との間に吸収体１７が介在されてなるものである。製造に際しては、外装体２０の内面（上面）に対して内装体１０の裏面がホットメルト接着剤などの接合手段によって接合（図２の点模様部分）された後に、内装体１０及び外装体２０が前身頃Ｆ及び後身頃Ｂの境界である前後方向（縦方向）中央で折り畳まれ、その両側部が相互に熱溶着又はホットメルト接着剤などによって接合されてサイドシール部２１が形成されることによって、ウエスト開口及び左右一対の脚開口が形成されたパンツタイプ使い捨ておむつとなる。 Figures 1 to 6 show pants-type disposable diapers. This pants-type disposable diaper (hereinafter, also simply referred to as a diaper) has an exterior body 20 extending from the front body F and the back body B, and an interior body fixed to the inner surface of the exterior body 20 so as to extend from the front body F to the back body B. The interior body 10 is formed by interposing an absorber 17 between the liquid-permeable top sheet 11 and the liquid-impermeable sheet 12. In manufacturing, the back surface of the interior body 10 is joined to the inner surface (upper surface) of the exterior body 20 by a joining means such as a hot melt adhesive (dot pattern portion in FIG. 2), and then the interior body 10 and the exterior body 20 are joined. Is folded at the center in the front-rear direction (longitudinal direction), which is the boundary between the front body F and the back body B, and both side portions thereof are joined to each other by heat welding or hot melt adhesive to form the side seal portion 21. This results in a pants-type disposable diaper with a waist opening and a pair of left and right leg openings.
　（内装体の構造例）
　内装体１０は、図３に示すように、トップシート１１と液不透過性シート１２との間に、吸収体１３を介在させた構造を有しており、トップシート１１を透過した排泄液を吸収体１３により吸収保持するものである。内装体１０の平面形状は特に限定されないが、図示形態のようにほぼ長方形とすることが一般的である。 (Example of interior structure)
As shown in FIG. 3, the interior body 10 has a structure in which an absorber 13 is interposed between the top sheet 11 and the liquid impermeable sheet 12, and excreted liquid that has permeated the top sheet 11 is collected. It is absorbed and held by the absorber 13. The planar shape of the interior body 10 is not particularly limited, but it is generally a substantially rectangular shape as shown in the illustrated form.
　吸収体１３の表側（肌当接面側）を覆うトップシート１１としては、有孔又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は、ポリエチレン又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。トップシート１１に多数の透孔を形成した場合には、尿などが速やかに吸収されるようになる。図示形態では、トップシート１１は、吸収体１７の側縁部を巻き込んで吸収体１３の裏側まで延在されている。 As the top sheet 11 that covers the front side (skin contact surface side) of the absorber 13, a perforated or non-perforated non-woven fabric, a porous plastic sheet, or the like is preferably used. The material fibers constituting the non-woven fabric can be olefin-based fibers such as polyethylene or polypropylene, synthetic fibers such as polyester-based and polyamide-based, recycled fibers such as rayon and cupra, and natural fibers such as cotton. , A non-woven fabric obtained by an appropriate processing method such as 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 that it is rich in flexibility and drapeability, and the thermal bond method is excellent in that it is bulky and soft. When a large number of through holes are formed in the top sheet 11, urine or the like is rapidly absorbed. In the illustrated form, the top sheet 11 extends to the back side of the absorber 13 by involving the side edge portion of the absorber 17.
　吸収体１３の裏側（非肌当接面側）を覆う液不透過性シート１２は、ポリエチレン又はポリプロピレンなどの液不透過性プラスチックシートが用いられるが、近年はムレ防止の点から透湿性を有するものが好適に用いられる。この遮水・透湿性シートとしては、例えばポリエチレンやポリプロピレン等のオレフィン樹脂中に、炭酸カルシウム等の無機微粒子を溶融混練してシートを形成した後、一軸又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を好適に用いることができる。図示形態では、液不透過性シート１２は、トップシート１１とともに吸収体１３の幅方向両側で裏側に折り返されているが、このような構造に限定されず、公知の他の構造を採用することができる。 A liquid-impermeable plastic sheet such as polyethylene or polypropylene is used as the liquid-impermeable sheet 12 that covers the back side (non-skin contact surface side) of the absorber 13, but in recent years, it has moisture permeability from the viewpoint of preventing stuffiness. Those are preferably used. The water-impervious / moisture-permeable sheet can be obtained by melting and kneading inorganic fine particles such as calcium carbonate in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet in the uniaxial or biaxial direction. A microporous sheet can be preferably used. In the illustrated form, the liquid-impermeable sheet 12 is folded back on both sides in the width direction of the absorber 13 together with the top sheet 11, but the structure is not limited to this, and other known structures may be adopted. Can be done.
　内装体１０の両側部には主に脚周りにフィットする立体ギャザーＢＳが形成されている。この立体ギャザーＢＳは、内装体１０の裏面の側部に固定された固定部と、この固定部から内装体の側方を経て内装体の表面の側部まで延在する本体部と、本体部の前後端部が倒伏状態で内装体の表面の側部に固定されて形成された倒伏部分と、この倒伏部分間が非固定とされて形成された自由部分とが、折り返しによって二重シートとしたギャザーシート１５により形成されており、二重シートの間には、自由部分の先端部等に細長状のギャザー弾性部材１６が配設されている。そしてこのような構造により、立体ギャザーＢＳは、ギャザー弾性部材１６の収縮により吸収体側縁部より突出する自由部分が、製品状態において立ち上がるようになっている。ギャザーシート１５としては撥水性とされた不織布が好適に用いられる。 Three-dimensional gather BSs that mainly fit around the legs are formed on both sides of the interior body 10. The three-dimensional gather BS includes a fixed portion fixed to a side portion on the back surface of the interior body 10, a main body portion extending from this fixed portion to a side portion on the surface of the interior body via the side of the interior body, and a main body portion. The inverted part formed by fixing the front and rear ends of the interior body to the side part of the surface of the interior body in the inverted state, and the free part formed by making the portion of the inverted part non-fixed are folded into a double sheet. It is formed of the gathered sheet 15, and an elongated gather elastic member 16 is arranged at the tip of a free portion or the like between the double sheets. With such a structure, in the three-dimensional gather BS, the free portion protruding from the side edge portion of the absorber due to the contraction of the gather elastic member 16 rises in the product state. As the gather sheet 15, a non-woven fabric having water repellency is preferably used.
　ギャザー弾性部材１６としては、通常使用されるスチレン系ゴム、オレフィン系ゴム、ウレタン系ゴム、エステル系ゴム、ポリウレタン、ポリエチレン、ポリスチレン、スチレンブタジエン、シリコーン、ポリエステル等の素材を用いることができる。また、外側から見え難くするため、太さは９２５ｄｔｅｘ以下、テンションは１５０～３５０％、間隔は７．０ｍｍ以下として配設するのがよい。なお、ギャザー弾性部材１６としては、図示形態のような糸状の他、ある程度の幅を有するテープ状のものを用いることもできる。 As the gather elastic member 16, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, and polyester, which are usually used, can be used. Further, in order to make it difficult to see from the outside, it is preferable to arrange the thickness at 925 dtex or less, the tension at 150 to 350%, and the interval at 7.0 mm or less. As the gather elastic member 16, a tape-shaped member having a certain width may be used in addition to the thread-shaped member as shown in the illustrated figure.
　前述のギャザーシート１５を構成する素材繊維もトップシート１１と同様に、ポリエチレン又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方法に得られた不織布を用いることができるが、特にはムレを防止するために坪量を抑えて通気性に優れた不織布を用いるのがよい。さらにギャザーシート１５については、尿などの透過を防止するとともに、カブレを防止しかつ肌への感触性（ドライ感）を高めるために、シリコーン系、パラフィン金属系、アルキルクロミッククロライド系撥水剤などをコーティングした撥水処理不織布を用いるのが望ましい。 Similar to the top sheet 11, the material fibers constituting the gather sheet 15 are synthetic fibers such as olefins such as polyethylene and polypropylene, polyesters and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. It can be a fiber, and a non-woven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. It is better to use a non-woven fabric that suppresses and has excellent breathability. Further, regarding the gather sheet 15, in order to prevent the permeation of urine and the like, prevent fogging, and enhance the feel (dry feeling) to the skin, a silicone-based, paraffin metal-based, alkylchromic chloride-based water repellent, etc. It is desirable to use a water-repellent treated non-woven fabric coated with.
　（外装体の構造例）
　外装体２０は、図３～図５にも示されるように、それぞれ不織布等からなる押さえシート２０Ａ及びバックシート２０Ｂからなる２層構造とされ、押さえシート２０Ａとバックシート２０Ｂとの間、及びバックシート２０Ｂをウエスト開口の縁で内面側に折り返してなる折り返し部分２０Ｃのシート間に弾性部材２４～２８が配設され、自然長状態で弾性部材の収縮力により外装体２０が収縮することにより、外装体２０に伸縮性が付与されている。平面形状は、中間両側部にそれぞれ脚開口を形成するために形成された凹状の脚周りライン２９により、全体としてほぼ砂時計形状をなしている。 (Structural example of exterior body)
As shown in FIGS. 3 to 5, the exterior body 20 has a two-layer structure composed of a pressing sheet 20A made of a non-woven fabric or the like and a back sheet 20B, respectively, and is between the pressing sheet 20A and the back sheet 20B and the back. Elastic members 24 to 28 are arranged between the sheets of the folded portion 20C formed by folding the sheet 20B to the inner surface side at the edge of the waist opening, and the exterior body 20 contracts due to the contraction force of the elastic member in the natural length state. Elasticity is imparted to the exterior body 20. The planar shape is substantially an hourglass shape as a whole due to the concave leg circumference lines 29 formed to form leg openings on both sides of the middle.
　図示形態の外装体２０においては、弾性部材として、図１～図２に示される展開形状において、ウエスト開口近傍２３に配置されたウエスト弾性部材２４と、前身頃Ｆ及び後身頃Ｂに、縦方向に間隔をおいて幅方向に沿って配置された複数のウエスト下方弾性部材２５とを有するとともに、前身頃Ｆ及び後身頃Ｂのそれぞれにおいて、ウエスト下方弾性部材２５の群とは別に、一方のサイドシール部２１から一方の脚開口に沿って股間部分に向かい、股間部分を横断し、かつ他方の脚開口に沿って他方のサイドシール部２１に至るパターンで湾曲しつつ延在する、互いに交差することなく間隔をおいて配置された複数本の湾曲弾性部材２６，２８を備えている。これら、弾性部材２４～２８は、それぞれその延在方向に沿って所定の伸長率で伸長された状態で固定されている。なお、本外装体２０では、脚周りライン２９に沿って前身頃Ｆのサイドシール部から後身頃Ｂのサイドシール部まで連続する弾性部材は設けられていない。 In the exterior body 20 of the illustrated form, as elastic members, in the developed shape shown in FIGS. 1 to 2, the waist elastic member 24 arranged in the vicinity of the waist opening 23, and the front body F and the back body B in the vertical direction. It has a plurality of lower waist elastic members 25 arranged along the width direction at intervals, and one side of each of the front body F and the rear body B, apart from the group of the lower waist elastic members 25. Crossing each other, curving and extending from the seal 21 to the crotch along one leg opening, across the crotch, and along the other leg opening to the other side seal 21. It includes a plurality of curved elastic members 26, 28 that are arranged at intervals without any problem. These elastic members 24 to 28 are fixed in a state of being extended at a predetermined extension rate along the extending direction thereof. The exterior body 20 is not provided with an elastic member that is continuous from the side seal portion of the front body F to the side seal portion of the rear body B along the leg circumference line 29.
　ウエスト弾性部材２４は、前身頃Ｆと後身頃Ｂとが接合されたサイドシール部２１の範囲の内、ウエスト開口の縁の近傍に縦方向に間隔をおいて配置された複数本の糸ゴム等の細長状の弾性部材であり、身体の胴周りを締め付けるように伸縮力を与えることによりおむつを身体に装着するためのものである。このウエスト弾性部材２４は、図示例では糸ゴムを用いたが、例えばテープ状の伸縮部材を用いてもよい。また、図示形態のウエスト弾性部材２４は、ウエスト部におけるバックシート２０Ｂの折り返し部分２０Ｃの不織布間に挟持されているが、押えシート２０Ａとバックシート２０Ｂとの間に挟持しても良い。 The waist elastic member 24 includes a plurality of thread rubbers and the like arranged at intervals in the vertical direction in the vicinity of the edge of the waist opening within the range of the side seal portion 21 in which the front body F and the back body B are joined. It is an elongated elastic member of the above, and is for attaching a diaper to the body by applying an elastic force so as to tighten the circumference of the body. Although thread rubber is used for the waist elastic member 24 in the illustrated example, for example, a tape-shaped elastic member may be used. Further, although the waist elastic member 24 of the illustrated form is sandwiched between the non-woven fabrics of the folded portion 20C of the back sheet 20B at the waist portion, it may be sandwiched between the pressing sheet 20A and the back sheet 20B.
　ウエスト下方弾性部材２５は、サイドシール部２１を有する前後方向の範囲に、縦方向に間隔をおいて配置された糸ゴム等の細長状の弾性部材であり、前身頃Ｆ及び後身頃Ｂの腰周り部分に夫々幅方向の伸縮力を与え、おむつを身体に密着させるためのものである。なお、ウエスト弾性部材２４とウエスト下方弾性部材２５との境界は必ずしも明確でなくてよい。例えば、前身頃Ｆ及び後身頃Ｂに縦方向に間隔をおいて幅方向に配置された弾性部材の内、数は特定できなくても、上部側の何本かがウエスト弾性部材として機能し、残りの弾性部材がウエスト下方弾性部材として機能していればよい。 The waist lower elastic member 25 is an elongated elastic member such as a rubber thread arranged at intervals in the vertical direction in a range in the front-rear direction having a side seal portion 21, and is a waist of a front body F and a back body B. The purpose is to give elastic force in the width direction to the surrounding parts to bring the diaper into close contact with the body. The boundary between the waist elastic member 24 and the waist lower elastic member 25 does not necessarily have to be clear. For example, among the elastic members arranged in the width direction at intervals in the vertical direction on the front body F and the back body B, some of the elastic members on the upper side function as waist elastic members even if the number cannot be specified. It suffices that the remaining elastic member functions as the elastic member below the waist.
　後身頃Ｂにおいて、ウエスト下方弾性部材２５とは別に配設された背側湾曲弾性部材２６は、糸ゴム等の細長状の弾性部材であり、所定の曲線に沿って配置されている。背側湾曲弾性部材２６は、一本であっても良いが複数本であるのが好ましく、図示例では４本の糸ゴム等の細長状の弾性部材であり、これら背側湾曲弾性部材２６は互いに交差することなく、間隔をおいて配置されている。この背側湾曲弾性部材２６は、２，３本程度の弾性部材を間隔を密にして実質的に一束として配置されるのではなく、所定の伸縮ゾーンを形成するように３～２０ｍｍ、好ましくは６～１６ｍｍ程度の間隔を空けて、３本以上、好ましくは４本以上配置される。 In the back body B, the dorsal curved elastic member 26 arranged separately from the waist lower elastic member 25 is an elongated elastic member such as rubber thread, and is arranged along a predetermined curve. The dorsal curved elastic member 26 may be one, but is preferably a plurality, and in the illustrated example, it is an elongated elastic member such as four rubber threads, and these dorsal curved elastic members 26 are They are spaced apart from each other without intersecting each other. The dorsal curved elastic member 26 is not substantially arranged as a bundle with a few elastic members closely spaced, but is preferably 3 to 20 mm so as to form a predetermined expansion / contraction zone. 3 or more, preferably 4 or more, are arranged at intervals of about 6 to 16 mm.
　外装体２０の前身頃Ｆにおいて、ウエスト下方弾性部材２５とは別に配設された腹側湾曲弾性部材２８は糸ゴム等の細長状の弾性部材であり、所定の曲線に沿って配置されている。腹側湾曲弾性部材２８は、一本であっても良いが複数本であるのが好ましく、図示例では４本の糸状弾性部材であり、これら腹側湾曲弾性部材２８は、互いに交差することなく、間隔をおいて配置されている。この腹側湾曲弾性部材２８も、２，３本程度の弾性部材を間隔を密にして実質的に一束として配置されるのではなく、所定の伸縮ゾーンを形成するように３～２０ｍｍ、好ましくは６～１６ｍｍ程度の間隔を空けて、３本以上、好ましくは４本以上配置される。 In the front body F of the exterior body 20, the ventral curved elastic member 28 arranged separately from the waist lower elastic member 25 is an elongated elastic member such as rubber thread, and is arranged along a predetermined curve. .. The ventral curved elastic member 28 may be one, but is preferably a plurality, and in the illustrated example, there are four filamentous elastic members, and these ventral curved elastic members 28 do not intersect with each other. , Are placed at intervals. The ventral curved elastic member 28 is not substantially arranged as a bundle with a few elastic members closely spaced, but is preferably 3 to 20 mm so as to form a predetermined expansion / contraction zone. 3 or more, preferably 4 or more, are arranged at intervals of about 6 to 16 mm.
　なお、図２に示すように、前身頃Ｆ及び後身頃Ｂに配置されたウエスト下方弾性部材２５及び湾曲弾性部材２６，２８は、製造時に外装体２０に対して連続的に固定した後に、吸収体１３と重なる部分の幅方向中間部（図中の二点鎖線で囲まれた部分）を、所定の切断パターンで細かく切断して収縮力が作用しない非収縮部分とし、この非収縮部分より側方に延在する部分を収縮力の作用する収縮部分（つまり、ウエスト下方弾性部材２５及び湾曲弾性部材２６，２８が連続的に残された部分）とすることができる。これにより、内装体（特に吸収体１３）の幅方向の不必要な収縮を防止することができる。もちろん、図８に示すように、ウエスト下方弾性部材２５及び湾曲弾性部材２６，２８を、内装体１０を横切って連続的に配置することもできる。 As shown in FIG. 2, the waist lower elastic members 25 and the curved elastic members 26 and 28 arranged on the front body F and the rear body B are absorbed after being continuously fixed to the exterior body 20 at the time of manufacture. The middle part in the width direction (the part surrounded by the alternate long and short dash line in the figure) of the part overlapping the body 13 is finely cut with a predetermined cutting pattern to form a non-shrinkable part on which no contraction force acts, and the side of the non-shrinkable part The portion extending in the direction can be a contraction portion on which a contraction force acts (that is, a portion in which the waist lower elastic member 25 and the curved elastic members 26 and 28 are continuously left). This makes it possible to prevent unnecessary shrinkage of the interior body (particularly the absorber 13) in the width direction. Of course, as shown in FIG. 8, the waist lower elastic members 25 and the curved elastic members 26 and 28 can be continuously arranged across the interior body 10.
　上述した外装体２０は、例えば特開平４－２８３６３号公報や、特開平１１－３３２９１３号公報記載の技術により製造することができる。また、湾曲弾性部材２６，２８を内装体１０上で切断し不連続化するには、特開２００２－３５０２９号公報、特開２００２－１７８４２８号公報及び特開２００２-２７３８０８号公報に記載される切断方法が好適に採用される。 The exterior body 20 described above can be manufactured by, for example, the techniques described in JP-A-4-28363 and JP-A-11-332913. Further, in order to cut the curved elastic members 26 and 28 on the interior body 10 to make them discontinuous, it is described in JP-A-2002-35029, JP-A-2002-178428 and JP-A-2002-273808. The cutting method is preferably adopted.
　図示例とは異なり、湾曲弾性部材２６，２８を、前身頃Ｆ及び後身頃Ｂのいずれか一方にのみ設けるだけでも良い。また、湾曲弾性部材２６，２８を、前身頃Ｆ及び後身頃Ｂの両方に設ける場合、前身頃Ｆ側に配置された湾曲弾性部材２８の群の一部又は全部と、後身頃Ｂ側に配置された湾曲弾性部材２６の群の一部又は全部とが交差する形態（図示せず）も採用できるが、図示例のように、前身頃Ｆ側に配置された湾曲弾性部材２８の群と、後身頃Ｂ側に配置された湾曲弾性部材２６の群とは互いに交差することなく前後方向中間部、特に前身頃Ｆに若干偏った位置で縦方向に離間している形態が好適である。 Unlike the illustrated example, the curved elastic members 26 and 28 may be provided only on either the front body F or the back body B. When the curved elastic members 26 and 28 are provided on both the front body F and the rear body B, a part or all of the group of the curved elastic members 28 arranged on the front body F side and the rear body B side are arranged. A form (not shown) in which a part or all of the group of the curved elastic members 26 intersects with each other can be adopted, but as shown in the illustrated example, the group of the curved elastic members 28 arranged on the front body F side and the group of the curved elastic members 28 are used. It is preferable that the group of the curved elastic members 26 arranged on the back body B side is separated from each other in the vertical direction at a position slightly deviated to the front-rear intermediate portion, particularly the front body F, without intersecting with each other.
　弾性部材２４～２８の固定時の伸長率は適宜定めることができるが、通常の成人用の場合、ウエスト弾性部材２４は１６０～３２０％程度、ウエスト下方弾性部材２５は１６０～３２０％程度、湾曲弾性部材２６，２８は２３０～３２０％程度とすることができる。 The elongation rate of the elastic members 24 to 28 at the time of fixing can be appropriately determined, but in the case of a normal adult, the waist elastic member 24 is about 160 to 320%, the waist lower elastic member 25 is about 160 to 320%, and is curved. The elastic members 26 and 28 can be about 230 to 320%.
　（カバーシート）
　図１及び図３にも示されるように、外装体２０の内面上に取り付けられた内装体１０の前後端部をカバーし、かつ内装体１０の前後縁からの漏れを防ぐために、カバーシート５０，６０が設けられていても良い。図示形態についてさらに詳細に説明すると、前カバーシート５０は、前身頃Ｆ内面のうちウエスト側端部の折り返し部分２０Ｃの内面から内装体１０の前端部と重なる位置まで幅方向全体にわたり延在しており、後カバーシート６０は、後身頃Ｂ内面のうちウエスト側端部の折り返し部分２０Ｃの内面から内装体１０の後端部と重なる位置まで幅方向全体にわたり延在している。外装体２０をおむつ内面に折り返してなる折り返し部分２０Ｃを、内装体１０と重なる部分まで延在させて、図示例のカバーシート５０，６０と同等の部分を形成することもできる。 (Cover sheet)
As shown in FIGS. 1 and 3, the cover sheet 50 is used to cover the front and rear ends of the interior body 10 mounted on the inner surface of the exterior body 20 and to prevent leakage from the front and rear edges of the interior body 10. , 60 may be provided. Explaining the illustrated form in more detail, the front cover sheet 50 extends over the entire width direction from the inner surface of the folded portion 20C of the waist side end portion of the inner surface of the front body F to the position where it overlaps with the front end portion of the interior body 10. The rear cover sheet 60 extends over the entire width direction from the inner surface of the folded portion 20C of the waist side end portion of the inner surface of the rear body B to the position where it overlaps with the rear end portion of the interior body 10. It is also possible to extend the folded portion 20C formed by folding the outer body 20 to the inner surface of the diaper to a portion overlapping the inner body 10 to form a portion equivalent to the cover sheets 50 and 60 of the illustrated example.
　（吸収体の構造について）
　吸収体１３は図３～図５に示すように単層構造となっていても、複数の層から成る構造となっていてもよい。
　吸収体１３としては、公知のもの、例えば、パルプ繊維の積繊体、セルロースアセテート等のフィラメントの集合体、あるいは不織布を基本とし、必要に応じて高吸収性ポリマーを混合、固着等してなるものを用いることができる。
　吸収体１３は、形状及びポリマー保持等のため、必要に応じてクレープ紙等の、液透過性及び液保持性を有する包装シート１４によって包装することができる。
　吸収体１３は、股間部に前後両側よりも幅の狭い括れ部分を有する砂時計状に形成されているが、長方形状等、適宜の形状とすることができる。 (About the structure of the absorber)
The absorber 13 may have a single-layer structure as shown in FIGS. 3 to 5, or may have a structure composed of a plurality of layers.
The absorber 13 is based on a known material, for example, a stack of pulp fibers, an aggregate of filaments such as cellulose acetate, or a non-woven fabric, and if necessary, a highly absorbent polymer is mixed and fixed. Can be used.
The absorber 13 can be wrapped with a wrapping sheet 14 having liquid permeability and liquid retention, such as crepe paper, if necessary, for shape, polymer retention, and the like.
The absorber 13 is formed in an hourglass shape having a constricted portion narrower than both front and rear sides in the crotch portion, but may have an appropriate shape such as a rectangular shape.
　（ミシン目の構造について）
　図７～１６は、パンツタイプ使い捨て着用物品である、パンツタイプ使い捨ておむつにおけるミシン目６１、６２付近を拡大して示す図である。
　以下、図７を参照しつつ、ミシン目について説明する。ミシン目６１、６２は、サイドシール２１の幅方向中央側に位置し、サイドシールに沿って伸びる部位である。ミシン目は、外装体をミシン目に沿って切り離し可能な部位である。 (About the structure of the perforation)
7 to 16 are enlarged views of the perforations 61 and 62 of the pants-type disposable diaper, which is a pants-type disposable diaper.
Hereinafter, the perforations will be described with reference to FIG. 7. The perforations 61 and 62 are located on the center side in the width direction of the side seal 21 and extend along the side seal. The perforation is a part where the exterior body can be separated along the perforation.
　第１形態のミシン目は、図７より、ミシン目は縦方向に延びる第１ミシン目６１と、この第１ミシン目の下端又は上端から、サイドシール２１に斜め下向き又は上向きに延びる第２ミシン目６２とを有する。そして、第１と第２の２つのミシン目で１つの単位を作っており、このミシン目単位が縦方向に１０個～２５個、１０ｍｍ以下の間隔で繰り返し設けられている。ミシン目単位間の間隔が狭い方が、横裂けは生じにくく、縦の切り離しが円滑に進みやすい。ミシン目単位間の間隔が１０ｍｍを超えると、縦方向の切り離しが止まり、横裂けが生じる恐れがある。 As shown in FIG. 7, the perforations of the first form are the first perforation 61 extending in the vertical direction and the second perforation extending diagonally downward or upward from the lower end or the upper end of the first perforation to the side seal 21. It has 62 and. Then, one unit is made by the first and second perforations, and the perforation units are repeatedly provided in the vertical direction at intervals of 10 to 25 and 10 mm or less. The narrower the interval between perforations, the less likely it is that horizontal tears will occur, and the smoother the vertical separation will be. If the distance between the perforation units exceeds 10 mm, the vertical separation may stop and lateral tearing may occur.
　ミシン目の孔は、外装体２０を貫いており、第２ミシン目６２と第１ミシン目６１の延長線６３のなす角αは特に限定されず、好ましくは２０°～７０°、より好ましくは４５°であり、サイドシール２１と第２ミシン目端の幅方向の距離６２Ｗが好ましくは１ｍｍ～１５ｍｍであり、第１ミシン目６１の長さ６１Ｌが１０ｍｍ、好ましくは５ｍｍ～１５ｍｍであり、第２ミシン目６２の長さ６２Ｌが７ｍｍ、好ましくは３ｍｍ～１０ｍｍであり、第１ミシン目が第２ミシン目よりも長いことが好ましく（６１Ｌ＞６２Ｌ）、ミシン目の孔が１ｍｍ～４ｍｍである。
　第１ミシン目、第２ミシン目の長さ、角度、及び孔のカットサイズは適宜定めることができるが、本形態の範囲内であると好ましい。 The perforated hole penetrates the exterior body 20, and the angle α formed by the extension line 63 of the second perforation 62 and the first perforation 61 is not particularly limited, and is preferably 20 ° to 70 °, more preferably. It is 45 °, the distance 62W between the side seal 21 and the end of the second perforation in the width direction is preferably 1 mm to 15 mm, and the length 61L of the first perforation 61 is 10 mm, preferably 5 mm to 15 mm. The length 62L of the second perforation 62 is 7 mm, preferably 3 mm to 10 mm, the first perforation is preferably longer than the second perforation (61L> 62L), and the perforation hole is 1 mm to 4 mm. ..
The length, angle, and cut size of the holes of the first perforation and the second perforation can be appropriately determined, but are preferably within the range of this embodiment.
　パンツタイプ使い捨ておむつによれば、ミシン目は、前身頃Ｆと後身頃Ｂとにそれぞれ一対設けられている。そのため、例えば、着用者がパンツタイプ使い捨ておむつを着用している状態において、１つのミシン目を順次切り離しことも、一対のミシン目を同時に切り離すことも、腹側からでも背側からでも可能である。
　また、前身頃のみ、後身頃のみにミシン目は設けられることも可能で、前身頃、後身頃のどちら側に設けられていてもよい。
　ミシン目は、サイドシール２１から幅方向中央側の内装体１０までの間に設置されているものとする。 According to the pants-type disposable diaper, a pair of perforations are provided on the front body F and the back body B, respectively. Therefore, for example, when the wearer is wearing a pants-type disposable diaper, one perforation can be sequentially separated, and a pair of perforations can be separated at the same time from the ventral side or the dorsal side. ..
Further, the perforations can be provided only on the front body and only on the back body, and may be provided on either the front body or the back body side.
It is assumed that the perforations are installed between the side seal 21 and the interior body 10 on the center side in the width direction.
　上述の実施形態において、以下の形態を適用することも可能である。各形態は、各自変形に適宜組み合わされてもよい。 In the above-described embodiment, the following modes can also be applied. Each form may be appropriately combined with each deformation.
　図７は、第１の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。拡大図では、弾性部材２４、２５は省略する。ウエスト開口から脚開口へ、縦方向下向きに切り離しが可能である。第１ミシン目下端から斜め方向下側に下方向第２ミシン目が延びている。下方向第２ミシン目６２下端での切り離しにかかる力が、次の単位の第１ミシン目６１へ向かうため、縦方向の連続した切り離しが可能である。
　前記第１ミシン目端と、前記サイドシール側に斜めに延びる第２ミシン目始点は、繋がっていることが好ましく、前記第１ミシン目と前記第２ミシン目が一連となっていることで、切り離しが前記第１ミシン目から前記第２ミシン目へと連続して起きる。
　この第１ミシン目端と第２ミシン目始点への連続性は、すべての実施形態で設けることが好ましい。
　また、サイドシール２１が下方向第２ミシン目６２延長線上にあるため、万一、第２ミシン目端部における切り離しが第１ミシン目６１に戻らなかった場合でも、サイドシール２１に沿って脚開口へ切り離しが進む。サイドシール２１自体は強いため、途中で横裂けは生じにくい。 FIG. 7 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the first embodiment. In the enlarged view, the elastic members 24 and 25 are omitted. It can be separated vertically downward from the waist opening to the leg opening. The second downward perforation extends diagonally downward from the lower end of the first perforation. Since the force applied to the lower end of the lower second perforation 62 toward the first perforation 61 of the next unit, continuous separation in the vertical direction is possible.
The end of the first perforation and the start point of the second perforation that extends diagonally to the side seal side are preferably connected, and the first perforation and the second perforation are in a series. Separation occurs continuously from the first perforation to the second perforation.
The continuity between the end of the first perforation and the start of the second perforation is preferably provided in all embodiments.
Further, since the side seal 21 is on the extension line of the second perforation 62 in the downward direction, even if the disconnection at the end of the second perforation does not return to the first perforation 61, the leg is along the side seal 21. Separation proceeds to the opening. Since the side seal 21 itself is strong, lateral tearing is unlikely to occur in the middle.
　図８は、第１の形態の変形例におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。第１ミシン目６１の長さよりも第２ミシン目６２の長さが短い。これにより、切り離しが横よりも縦に進む勢いが強くなるため、力が強くない利用者でも、おむつを切り離すことが容易にできる。 FIG. 8 is an enlarged view of the vicinity of the perforation of the pants-type disposable diaper in the modified example of the first form. The length of the second perforation 62 is shorter than the length of the first perforation 61. As a result, the momentum for the separation to proceed vertically rather than horizontally becomes stronger, so that even a user who does not have strong force can easily separate the diaper.
　図９は、第１の形態の変形例におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。拡大図では、弾性部材２４、２５は省略する。拡大図に示すように、第２ミシン目６２の終点から幅方向中央側延長線上に、第１ミシン目６１の孔部分が位置している。横裂けが生じた場合でも、横裂けの先には、第１ミシン目が配置されており、横裂けを第１ミシン目で受け止めるので、縦方向への切り離しが連続して可能である。 FIG. 9 is an enlarged view of the vicinity of the perforation of the pants-type disposable diaper in the modified example of the first form. In the enlarged view, the elastic members 24 and 25 are omitted. As shown in the enlarged view, the hole portion of the first perforation 61 is located on the extension line on the center side in the width direction from the end point of the second perforation 62. Even when a lateral tear occurs, the first perforation is arranged at the tip of the lateral tear, and the lateral tear is received by the first perforation, so that the lateral tear can be continuously separated in the vertical direction.
　図１０は、第１の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。第２ミシン目６２の向きが図７で示す第１の形態と反対に当たる、上方向第２ミシン目が設けられており、脚開口からウエスト開口へ、縦方向上向きに切り離しが可能である。
　図７同様に、サイドシール２１が上方向第２ミシン目６２延長線上にあるため、万一、第２ミシン目端部における切り離しが第１ミシン目６１に戻らなかった場合でも、サイドシール２１に沿って脚開口へ切り離しが進む。サイドシール２１自体は強いため、途中で横裂けは生じにくい。
　下から上への切り離しが出来る形態は、介助者がおむつを切り離し、交換する際に使いやすい。また、力の弱い利用者は、下から上へ引っ張る力の方が、上から下へおろす力より強いため、おむつを切り離すことが容易にできる。 FIG. 10 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the first embodiment. An upward second perforation is provided in which the direction of the second perforation 62 is opposite to that of the first form shown in FIG. 7, and the second perforation can be separated vertically upward from the leg opening to the waist opening.
Similarly to FIG. 7, since the side seal 21 is on the extension line of the second perforation 62 in the upward direction, even if the disconnection at the end of the second perforation does not return to the first perforation 61, the side seal 21 can be used. Separation proceeds to the leg opening along. Since the side seal 21 itself is strong, lateral tearing is unlikely to occur in the middle.
The form that can be separated from the bottom to the top is easy for the caregiver to use when separating and changing the diaper. Further, a user with a weak force can easily separate the diaper because the force of pulling from the bottom to the top is stronger than the force of pulling down from the top to the bottom.
　図１１は、第１の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態は、図７と図１０に示す形態を併せ持ち、第１ミシン目上端と下端それぞれから、上方向第２ミシン目６２Ａ及び下方向第２ミシン目６２Ｂを有する。そのため、切り離しが縦方向下向きにも、縦方向上向きにも可能であり、力の弱い要介護者自身の切り離しも、他人によるおむつ交換の際の切り離しも、双方向から容易にできる。 FIG. 11 is an enlarged view of the vicinity of the perforation of the pants-type disposable diaper in the first embodiment. This embodiment has both the forms shown in FIGS. 7 and 10, and has an upward second perforation 62A and a downward second perforation 62B from the upper end and the lower end of the first perforation, respectively. Therefore, the separation can be performed either vertically downward or vertically upward, and the person requiring long-term care who has weak power can be separated easily, or the diaper can be easily separated when another person changes the diaper.
　図１２では、第２の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態では、下方向第２ミシン目６２が、次の単位ミシン目の第１ミシン目６１に向かい、逆方向下向きに折り返している。第２ミシン目６２終点が次の単位の第１ミシン目６１始点に向かうことで、切り離しの向きが次のミシン目単位へ誘導され、ミシン目間での横裂けが生じにくく、図７から１１までの第１の形態よりも切り離しがスムーズに進む。 FIG. 12 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the second form. In this embodiment, the downward second perforation 62 is turned downward in the opposite direction toward the first perforation 61 of the next unit perforation. By moving the end point of the second perforation 62 toward the start point of the first perforation 61 of the next unit, the direction of separation is guided to the next perforation unit, and lateral tearing between the perforations is unlikely to occur. Separation proceeds more smoothly than in the first form up to.
　図１３は、第３の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態では、図１２の形態のミシン目が、縦方向下から上に向かう。上方向第２ミシン目６２が、次の単位ミシン目の第１ミシン目６１に向かい、逆方向上向きに折り返している。切り離しの向きが次のミシン目単位へ誘導され、ミシン目間での横裂けが生じにくく、図７から１１までの第１の形態よりも、切り離しがスムーズにつながる。
　下から上への切り離しが出来る形態は、介助者がおむつを切り離し、交換する際に使いやすい。また、力の弱い利用者は、下から上へ引っ張る力の方が、上から下へおろす力より強いため、おむつを切り離すことが容易にできる。 FIG. 13 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the third embodiment. In this embodiment, the perforations in the form of FIG. 12 are directed from the bottom to the top in the vertical direction. The second perforation 62 in the upward direction is turned upward in the opposite direction toward the first perforation 61 of the next unit perforation. The direction of separation is guided to the next perforation unit, lateral tearing between perforations is less likely to occur, and the separation is smoothly connected as compared with the first embodiment shown in FIGS. 7 to 11.
The form that can be separated from the bottom to the top is easy for the caregiver to use when separating and changing the diaper. Further, a user with a weak force can easily separate the diaper because the force of pulling from the bottom to the top is stronger than the force of pulling down from the top to the bottom.
　図１４は、第４の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態は、図１０及び１２で示す第１及び第２の形態の組み合わせから成る。拡大図では、弾性部材２４、２５は省略する。
　拡大図で示すように、下方向第２ミシン目６２Ｂ端逆方向下側折り返し６２Ｃの延長線６２Ｑ上に、次の単位の第１ミシン目６１があり、上方向第２ミシン目６２Ａの延長線６２Ｐ上に前の単位の下方向第２ミシン目６２Ｂが、配置されている。
　下方向第２ミシン目６２Ｂの長さは、サイドシール２１に寄りすぎないように、適度な長さを取ることが好ましい。上方向第２ミシン目延長線６２Ｐ、及び、下方向第２ミシン目端折り返し延長線６２Ｑの長さは、特に規定していない。下方向第２ミシン目端逆方向下側折り返し６２Ｃと第１ミシン目６１、及び、上方向第２ミシン目６２Ａと下方向第２ミシン目６２Ｂの少なくとも一方が接する形態も含まれる。
　本形態は、ミシン目間の距離が狭く、切り離す力がミシン目間で逃げにくいため、単位のミシン目間の誘導が生じやすく、引裂きがミシン目に沿って起こりやすくなる。 FIG. 14 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the fourth embodiment. This form comprises a combination of the first and second forms shown in FIGS. 10 and 12. In the enlarged view, the elastic members 24 and 25 are omitted.
As shown in the enlarged view, the first perforation 61 of the next unit is on the extension line 62Q of the lower second perforation 62B end reverse direction lower folding 62C, and the extension line of the upper second perforation 62A. The downward second perforation 62B of the previous unit is arranged on 62P.
It is preferable that the length of the second downward perforation 62B is an appropriate length so as not to be too close to the side seal 21. The lengths of the upward second perforation extension line 62P and the downward second perforation end folding extension line 62Q are not particularly specified. It also includes a form in which at least one of the lower second perforation 62C and the first perforation 61, and the upper second perforation 62A and the lower second perforation 62B are in contact with each other.
In this embodiment, since the distance between the perforations is narrow and the separating force is difficult to escape between the perforations, guidance between the perforations of the unit is likely to occur, and tearing is likely to occur along the perforations.
　図１５は、第５の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態では、第１ミシン目６１に沿って、おむつ幅方向中央側にウエスト開口から脚開口まで、補助ミシン目６４が配置されている。この補助ミシン目６４は、弾性部材２４、２５による切り離しの中断を起こりにくくするためのものである。
　第１ミシン目６１の孔が弾性部材２４，２５の上にない部分に、補助ミシン目６４の孔が配置されるため、縦方向の切り離しが弾性部材で止まり、横方向に裂けた場合でも、横裂けの先に補助ミシン目６４の孔があるために、再度切り離しが縦方向へ進む。補助ミシン目６４の孔が弾性部材２４，２５の上にない場合でも、横裂け近位にある補助ミシン目６４により縦方向への切り離しを再開できる。
　切り離しを補助、誘導する縦方向補助ミシン目６４の配置は、すべての実施例で設けることが可能である。 FIG. 15 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the fifth embodiment. In this embodiment, the auxiliary perforations 64 are arranged along the first perforation 61 from the waist opening to the leg opening on the center side in the diaper width direction. The auxiliary perforations 64 are for making it difficult for the elastic members 24 and 25 to interrupt the separation.
Since the holes of the auxiliary perforations 64 are arranged in the portions where the holes of the first perforations 61 are not above the elastic members 24 and 25, even if the vertical separation is stopped by the elastic members and the holes are torn in the horizontal direction. Since there is a hole in the auxiliary perforation 64 at the tip of the lateral tear, the disconnection proceeds in the vertical direction again. Even if the hole of the auxiliary perforation 64 is not on the elastic members 24 and 25, the vertical separation can be resumed by the auxiliary perforation 64 located proximal to the lateral tear.
The arrangement of the vertical auxiliary perforations 64 that assist and guide the disconnection can be provided in all the embodiments.
　図１６は、第６の形態におけるパンツタイプ使い捨ておむつのミシン目付近を拡大して示す図である。本形態では、第２ミシン目６２の終点から第２ミシン目の延長線上に、U字型の孔である、補助孔６５を配置することで、切り離しをサイドシール２１方向へ向かうことを起こりにくくし、次の第１ミシン目へと誘導する。
　この切り離しを補助、誘導する補助孔６５の配置は、すべての実施例で設けることが可能である。 FIG. 16 is an enlarged view showing the vicinity of the perforation of the pants-type disposable diaper in the sixth embodiment. In this embodiment, by arranging the auxiliary hole 65, which is a U-shaped hole, on the extension line of the second perforation from the end point of the second perforation 62, it is unlikely that the separation is directed toward the side seal 21. Then, it leads to the next first perforation.
The arrangement of the auxiliary holes 65 that assist and guide the disconnection can be provided in all the embodiments.
