Description

本発明は、着用時に吸収体が着用者の体表面に密着せず、排出された尿を着用者の皮膚になるべく接触させることなく効率的に吸収できるとともにライン工程で効率的に製造するのに適した構造の吸収体製品と、その製造方法に関するものである。   In the present invention, the absorbent body does not adhere to the wearer's body surface at the time of wearing, and the discharged urine can be efficiently absorbed without contacting the wearer's skin as much as possible. The present invention relates to an absorbent product having a suitable structure and a method for producing the same.

小児用もしくは成人用のオムツのような吸収体製品は、特許文献１（特開平０７−９６００４号公報）のように、一般に腰部の両脇で分離されて平らに展開でき、装着時に後側腰部と前側腰部とをテープで取り外し可能に連結する形式のテープ形と、特許文献２（特開平０８−５６９８７号公報）のように、ウェストホール部および２つのレッグホールを形成したパンツの形態のテープレス形とに大別される。いずれのタイプの吸収体製品であっても、シート状の防漏体の内面側に吸収体を設けた本体を有しており、この本体が、着用者の下半身（腹部・クロッチ部・背部）に着用され、吸収体が着用者の下半身の表面に密着するようになっている。そして、製品内で排出されて体表面と吸収体の間に回った尿を吸収体によって体表面から密着吸収するものである。   Absorbent products such as diapers for children or adults are generally separated on both sides of the waist as in Patent Document 1 (Japanese Patent Laid-Open No. 07-96004), and can be deployed flat. A tape in the form of removably connecting the front waist part with a tape, and a tape in the form of a pant in which a waist hole part and two leg holes are formed as in Patent Document 2 (Japanese Patent Laid-Open No. 08-56987) It is roughly divided into a loess shape. Any type of absorbent product has a main body with an absorbent body on the inner surface of the sheet-shaped leak preventer, and this main body is the lower body of the wearer (abdomen, crotch part, back) The absorbent body is in close contact with the surface of the lower body of the wearer. And the urine discharged | emitted within the product and rotated between the body surface and the absorber is closely absorbed from the body surface by the absorber.

しかしながら、従来の吸収体製品によれば、上述した通り、吸収体は着用者の体表面に密着しているため、排出された尿が体表面と吸収体のを伝って広く行き渡るのは困難である。このため、吸収体製品に組み込まれた吸収体の一部にしか尿が吸収されない傾向があり、吸収効率が低いという問題がある。また、密着吸収によれば着用者の体表面が尿で濡れることが避けられないため、着用者の皮膚が尿によってかぶれ易く、装着感もよくないという問題もあった。   However, according to the conventional absorbent product, as described above, since the absorbent body is in close contact with the body surface of the wearer, it is difficult for the discharged urine to spread widely through the body surface and the absorbent body. is there. For this reason, there is a tendency that urine is absorbed only in a part of the absorbent body incorporated in the absorbent body product, and the absorption efficiency is low. Further, according to close contact absorption, it is inevitable that the body surface of the wearer gets wet with urine, so that there is also a problem that the wearer's skin is easily rashed by urine and the feeling of wearing is not good.

本発明は、従来の吸収体製品において吸収メカニズムの基本原理として当然とされていた上記密着吸収の考え方に問題点を発見し、これによって本願発明者が新たに認識した上記課題を解決するためになされたものである。すなわち、本発明の目的は、吸収体を着用者の体表面から離す構造を採用することにより、全吸収体を効率的に使用して尿を確実に吸収するとともに、体表面に尿が接触しにくいために皮膚のかぶれが発生しにくく、着用感が良好な吸収体製品とその効率的な製造方法を提供することにある。   In order to solve the above-mentioned problems newly recognized by the present inventor, the present invention has found a problem in the above-mentioned concept of adhesion absorption, which has been taken as a basic principle of the absorption mechanism in conventional absorbent products. It was made.

It can be arbitrarily replaced with the configuration of and combined.

１．第１実施形態（図１〜図１７）：ストレートカット方式
（１）製造方法
本例の吸収体製品１ａは、従来とは異なる構造を備えたテープレス形（パンツタイプ）のおむつであり、図ごとに分説する以下の工程によって製造される。 1. 1st Embodiment (FIGS. 1-17): Straight cut system (1) Manufacturing method The absorber product 1a of this example is a tapeless type (pants type) diaper provided with a structure different from the conventional one. It is manufactured according to the following process described separately.

図１に示すように、本工程では、所定方向に連続する帯状の不織布２（ＰＰスパンメルト不織布等）と、所定方向に連続する帯状で前記不織布２よりも幅の小さい液不通過性シート３（通気性フィルム等）を使用する。所定方向とは、実際の製造工程では水平方向となるが、図では上下方向として表す。すなわち、不織布２を所定方向に連続して供給搬送しながら、所定位置において不織布２の幅方向（所定方向と直交する図中左右方向）の中央に、不織布２よりも幅の小さい液不通過性シート３を供給して重ね合せ、連続的に接合して所定方向に連続する帯状の防漏体を形成していく。   As shown in FIG. 1, in this step, a strip-shaped nonwoven fabric 2 (PP spun melt nonwoven fabric or the like) continuous in a predetermined direction and a liquid-impermeable sheet 3 (in a strip shape continuous in a predetermined direction and smaller in width than the nonwoven fabric 2) Use a breathable film. The predetermined direction is a horizontal direction in an actual manufacturing process, but is represented as a vertical direction in the figure. That is, while the non-woven fabric 2 is continuously supplied and conveyed in a predetermined direction, the liquid impermeability is smaller in width than the non-woven fabric 2 in the center of the non-woven fabric 2 in the width direction (left and right direction in the figure orthogonal to the predetermined direction) The sheet 3 is supplied, overlapped, and continuously joined to form a strip-shaped leak preventer continuous in a predetermined direction.

なお、接合はホットメルト樹脂等を利用して行う。その他の工程及び第２実施形態以下で説明する工程で行う接着も同様である。   The joining is performed using a hot melt resin or the like. The same applies to the other steps and the bonding performed in the steps described in the second embodiment and thereafter.

本例では、不織布２と液不通過性シート３の両方とも、図では所定方向の寸法が限定された短冊状に表現されているが、実際には所定方向について長尺帯状の材料であって、工程の材料供給箇所においては例えばロール状の形態で収納されており、工程の進捗に合せて所定方向に材料を繰り出して所定方向に搬送する構成となっている。なお、本例及び第２実施形態以降の説明においては、製造工程で使用する構成部材は、特にことわらない限り、前記不織布２や前記液不通過性シート３と同様、所定方向に連続している長尺帯状の材料であるものとする。   In this example, both the non-woven fabric 2 and the liquid impermeable sheet 3 are expressed in a strip shape in which the dimension in a predetermined direction is limited in the figure, but in actuality, it is a long strip material in the predetermined direction. The material supply location of the process is stored in, for example, a roll shape, and is configured so that the material is fed out in a predetermined direction and conveyed in a predetermined direction according to the progress of the process. In addition, in this example and description after 2nd Embodiment, the structural member used by a manufacturing process is continuous in a predetermined direction like the said nonwoven fabric 2 and the said liquid impervious sheet 3 unless there is particular notice. It is assumed that the material is a long belt-like material.

図２に示すように、液不通過性シート３の幅方向の中央部の上に、液不通過性シート３よりも幅の小さい複数の吸収体４を、所定方向について適宜間隔をおいて配置していく。吸収体４の種類は特に限定しないが、液吸収性材料自体以外の構成要素、例えば液吸収性材料に被せるトップシートやＡＱＬ（Aquisition Layer）等が必要であれば、これらが予め組み合わされたものを供給するか、又は図示はしないが工程中で吸収体４にこれらの構成要素を重ねる等、本吸収体製品１ａの仕様が要求する吸収体４の機能・構造に応じて対応するものとする。   As shown in FIG. 2, a plurality of absorbent bodies 4 having a width smaller than that of the liquid impermeable sheet 3 are arranged on the central portion in the width direction of the liquid impermeable sheet 3 at appropriate intervals in a predetermined direction. I will do it. The type of the absorbent body 4 is not particularly limited, but if a component other than the liquid absorbent material itself, for example, a top sheet or AQL (Aquisition Layer) to be placed on the liquid absorbent material is necessary, these are combined in advance. Although not shown, these components are stacked on the absorbent body 4 during the process, but this corresponds to the function / structure of the absorbent body 4 required by the specifications of the absorbent product 1a. .

図３に示すように、重ねられた不織布２と液不通過性シート３の幅方向に関する２つの境界部分、すなわち幅方向について不織布２と液不通過性シート３が隣接している所定方向に連続する２つの領域に、複数本の弾性部材５を所定方向に伸張させた状態でそれぞれ配置する。弾性部材５としてはポリウレタンフィラメント等が採用可能である。なお、この不織布２と液不通過性シート３の境界部分には後工程でレッグホール６を形成するので、弾性部材５を切断せずにレッグホール６を形成する余地を設けるとともに、レッグホール６の両側に弾性部材５が配置されるように、弾性部材５の間隔の中に相対的に広い間隔ａとなる部分を設ける。ここで、間隔ａとなるのは、不織布２に設けられた弾性部材５と液不通過性シート３に設けられた弾性部材５の間である。   As shown in FIG. 3, two boundary portions related to the width direction of the nonwoven fabric 2 and the liquid impermeable sheet 3 that are stacked, that is, continuous in a predetermined direction in which the nonwoven fabric 2 and the liquid impermeable sheet 3 are adjacent to each other in the width direction. A plurality of elastic members 5 are respectively arranged in two regions that are stretched in a predetermined direction. A polyurethane filament or the like can be used as the elastic member 5. In addition, since the leg hole 6 is formed in the boundary portion between the nonwoven fabric 2 and the liquid impermeable sheet 3 in a later step, there is provided a room for forming the leg hole 6 without cutting the elastic member 5, and the leg hole 6 A portion having a relatively wide interval a is provided in the interval between the elastic members 5 so that the elastic members 5 are disposed on both sides of the elastic member 5. Here, the distance a is between the elastic member 5 provided on the nonwoven fabric 2 and the elastic member 5 provided on the liquid-impermeable sheet 3.

図４に示すように、前記不織布２の幅方向の両側縁をそれぞれ内方に折り返し、前記弾性部材５を挟んで接着する。   As shown in FIG. 4, both side edges in the width direction of the nonwoven fabric 2 are folded inward, and the elastic member 5 is sandwiched between them.

図５に示すように、吸収体４の両側方にある２つの境界領域において、弾性部材５の間隔が広めのａとされた位置に、所定方向に沿ってレッグホール６をスリット状の開口として貫通して形成する。これによって、レッグホール６の上下（図中左右）に弾性部材５が配置されることとなり、着用時にはレッグホール６の全周が着用者の脚の周囲に弾性をもって密着するので吸収体製品１ａとしての密閉状態を保つことができる。   As shown in FIG. 5, in the two boundary regions on both sides of the absorber 4, the leg hole 6 is formed as a slit-shaped opening along a predetermined direction at a position where the distance between the elastic members 5 is a wide. Form through. As a result, the elastic member 5 is arranged above and below the leg hole 6 (left and right in the figure), and when worn, the entire circumference of the leg hole 6 is elastically adhered to the circumference of the wearer's leg. Can be kept sealed.

図６に示すように、吸収体４の幅方向の中央を通り、所定方向に平行な中心線に沿って、吸収体４が２つ折りになるとともに不織布２の幅方向の両側縁が重なるように、全体を折り返す。   As shown in FIG. 6, the absorbent body 4 is folded in half along the center line parallel to the predetermined direction through the center in the width direction of the absorbent body 4 so that both side edges in the width direction of the nonwoven fabric 2 overlap. Wrap the whole thing.

図７（ａ）において鎖線で示すように、所定方向と直交する方向に沿って吸収体４と吸収体４の間をシールカットすることにより、図７（ｂ）に示すような吸収体製品１ａに分離される。なお、図７（ｂ）に示す吸収体製品１ａの形状は、図７（ａ）に示すように所定方向について張力を与えて伸張されている状態でシールカットした瞬間の個々の製品を表すものであり、実際にはシールカットされて個々の製品に分離された瞬間に、弾性部材５の縮退によって図８（ａ）に示すようにレッグホール６よりも上方の部分（後述する胴体部７）が縮み、レッグホール６よりも下方の部分（後述する袋部８）が相対的に前後に張り出した外形になる。   As shown by a chain line in FIG. 7A, the absorbent product 1a as shown in FIG. 7B is cut by sealing between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction. Separated. In addition, the shape of the absorbent product 1a shown in FIG. 7 (b) represents individual products at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 7 (a). Actually, at the moment when the seal is cut and separated into individual products, the elastic member 5 is retracted, so that the portion above the leg hole 6 as shown in FIG. Shrinks, and a portion (bag portion 8 to be described later) below the leg hole 6 is relatively extended in the front-rear direction.

このように、本例の吸収体製品１ａの製造方法によれば、帯状の不織布２及び液不通過性シート３を重ねて水平方向に搬送しながら、その上に吸収体４を所定間隔で配置していき、同搬送方向に伸張させた弾性部材５を配置し、さらに搬送方向に平行な中心線で全体を２つ折りにして吸収体４，４間で次々とシールカットして個々の吸収体製品１ａに分離していくことができるので、吸収体製品１ａを容易かつ確実に大量生産することができる。   Thus, according to the manufacturing method of the absorbent product 1a of this example, the belt-shaped nonwoven fabric 2 and the liquid impermeable sheet 3 are stacked and conveyed in the horizontal direction, and the absorbent bodies 4 are arranged at predetermined intervals thereon. Then, the elastic member 5 extended in the carrying direction is arranged, and the whole is folded in half along the center line parallel to the carrying direction, and the individual absorbent bodies are cut and sealed one after another. Since it can isolate | separate into the product 1a, the absorber product 1a can be mass-produced easily and reliably.

なお、本例の製造方法では、図５（ａ）に示すように左右のレッグホール６，６をそれぞれ別々に形成したが、図６に示す工程において全体を折り返した後に、重ねた不織布２を貫通してカットすることにより、左右のレッグホール６，６を一括して形成してもよい。   In addition, in the manufacturing method of this example, as shown to Fig.5 (a), although the left and right legholes 6 and 6 were each formed separately, after the whole was turned in the process shown in FIG. The left and right leg holes 6 and 6 may be collectively formed by cutting through.

（２）構造（図８乃至図１１）
次に、以上の工程によって得られた吸収体製品１ａの構造を図８乃至図９を参照して説明する。図８乃至図９は本例の吸収体製品１ａを人体に装着したように広げた際の形態を示している。まず、胴体部７は、弾性部材５を挟んだ不織布２で構成される周状の部分であり、上下に貫通するウェストホール９を備えており、着用者の腰部に弾性的に密着して装着される。 (2) Structure (FIGS. 8 to 11)
Next, the structure of the absorbent product 1a obtained by the above steps will be described with reference to FIGS. FIG. 8 thru | or FIG. 9 has shown the form at the time of extending the absorber product 1a of this example so that it might mount | wear with a human body. First, the body portion 7 is a circumferential portion composed of the nonwoven fabric 2 with the elastic member 5 interposed therebetween, and is provided with a waist hole 9 penetrating vertically, and is attached elastically to the wearer's waist. Is done.

この胴体部７の下側に一体に構成された袋部８は、胴体部７のウェストホール９の下側の開口に上部開口１０で連通する袋体１１と、袋体１１の内部に収納された吸収体４からなる。袋体１１は、外側の不織布２と内側の液不通過性シート３で構成される防漏体からなり、吸収体４は袋体１１の底部に袋体１１の内面に沿って配置されている。そして、胴体部７と袋部８の両側面の各境界部分には、レッグホール６が開口したレッグホール部がそれぞれ形成されている。   The bag portion 8 integrally formed on the lower side of the body portion 7 is housed inside the bag body 11, a bag body 11 communicating with the opening on the lower side of the waist hole 9 of the body portion 7 through the upper opening 10. Consisting of the absorbent body 4. The bag body 11 is composed of a leak-proof body composed of the outer nonwoven fabric 2 and the inner liquid impermeable sheet 3, and the absorbent body 4 is disposed along the inner surface of the bag body 11 at the bottom of the bag body 11. . A leg hole portion in which the leg hole 6 is opened is formed at each boundary portion between both side surfaces of the body portion 7 and the bag portion 8.

従って、胴体部７と袋部８は、着用者の前後方向に沿う中心線で折り返した袋部８の底部を除き、着用者の腹部に対応する前部中央と着用者の背部に対応する後部中央をそれぞれ接合した構成となっている。   Therefore, the trunk | drum 7 and the bag part 8 are the rear part corresponding to the wearer's abdomen and the front center corresponding to a wearer's back | dorsal part except the bottom part of the bag part 8 turned back by the centerline along a wearer's front-back direction. The center is joined to each other.

かかる構造の吸収体製品１ａを着用する場合には、着用者は両脚をウェストホール９から胴体部７の中に入れた後、レッグホール６の内側から外側に突き出し、胴体部７を持ち上げて腰部の周囲に装着する。   When wearing the absorbent body product 1a having such a structure, the wearer puts both legs into the body part 7 from the waist hole 9, and then protrudes from the inside of the leg hole 6 to the outside, lifting the body part 7 and lifting the waist part. Attach around.

かかる着用状態において、吸収体４が収納された袋部８は、着用者の両脚の間において胴体部７から吊下がった形態となり、着用者の前下腹部からクロッチ部を経て後下背部に至る尿、便の***に関与する部位が、袋体１１の上部開口１０に臨んだ状態となる。すなわち、排出器と吸収体の存在する位置とは離れた状態になっている。着用者から***される尿や便の大部分は着用者の体表面に接触することなく上部開口１０から袋部８内に入ることができる。   In such a wearing state, the bag portion 8 in which the absorbent body 4 is housed is suspended from the body portion 7 between the wearer's legs, and reaches the rear lower back portion from the wearer's front lower abdomen through the crotch portion. A part involved in excretion of urine and feces is in a state of facing the upper opening 10 of the bag body 11. That is, the ejector and the position where the absorber exists are in a separated state. Most of the urine and feces excreted from the wearer can enter the bag portion 8 from the upper opening 10 without contacting the body surface of the wearer.

従来の吸収体製品によれば、体表面に吸収体を密着させて配置し、体表面と吸収体の間に流れた尿等を吸収体で密着吸収する方式がとられていたため、吸収体の全量を効率的に使用しにくく、皮膚が尿でかぶれる恐れがある他、着用感も良くなかったが、本例の吸収体製品１ａによれば、着用者の***する尿や便は着用者の体表面に接触することが少なく上部開口１０から袋部８内に入るので、尿等は袋体１１の内部で容易に移動して内部の吸収体４に効率的に吸収され、また吸収体４は袋体１１内に配置されて着用者の体表面からは常に離れた状態にあるので尿が吸収体４と皮膚の間に滞留することはなく、皮膚が尿でかぶれる恐れは少ない。また、着用感も良好である。   According to the conventional absorbent product, the absorber is placed in close contact with the body surface, and the method of closely adsorbing urine flowing between the body surface and the absorbent with the absorber has been adopted. The entire amount is difficult to use efficiently, the skin may be irritated, and the feeling of wearing is not good, but according to the absorbent product 1a of this example, the urine and feces excreted by the wearer are Since it does not come into contact with the body surface and enters the bag portion 8 from the upper opening 10, urine or the like easily moves inside the bag body 11 and is efficiently absorbed by the internal absorber 4. Is placed in the bag 11 and is always away from the body surface of the wearer, so that urine does not stay between the absorbent body 4 and the skin, and there is little possibility that the skin will be covered with urine. Moreover, a feeling of wear is also favorable.

また、胴体部７及びレッグホール６の下方には弾性部材５があるので、人体と接触する部分には高い密着性が得られ、液漏れや臭い漏れが防止される。   Moreover, since the elastic member 5 exists under the trunk | drum 7 and the leg hole 6, high adhesiveness is obtained in the part which contacts a human body, and a liquid leak and an odor leak are prevented.

また、図７（ｂ）に示すように、本例のレッグホール６は背部の接合部と腹部の接合部の中央よりもやや腹部よりに形成されているので、便を収容する容積が大きい。また、レッグホール６を背部の接合部と腹部の接合部の中央に形成し前後同形のものを作れば、前後の区別がなくなり前後を確かめることなく着用もできる。また、胴体部７の上縁に対して、レッグホール６を背部から腹部に向けて上るように傾斜して形成すれば、着用状態では袋部８の腹部側が下がり、尿は袋部８の前部に導かれやすくなり、逆にレッグホール６を背部から腹部に向けて下がるように傾斜して形成すれば、着用状態では袋部８の背部側が下がり、尿は袋部８の後部に導かれやすくなるので、予想される着用者の***に合せて袋体１１の適当な部分に尿を集まりやすく設定することが可能である。   Moreover, as shown in FIG.7 (b), since the leg hole 6 of this example is formed in the abdomen a little rather than the center of the junction part of a back part, and the junction part of an abdomen, the volume which accommodates a stool is large. Moreover, if the leg hole 6 is formed in the center of the junction part of a back part and the junction part of an abdomen and the thing of the front and back is the same shape, there will be no distinction of front and back, and it can wear without confirming front and back. Further, if the leg hole 6 is inclined with respect to the upper edge of the body part 7 so as to rise from the back part toward the abdomen, the abdomen side of the bag part 8 is lowered in the worn state, and urine is in front of the bag part 8. If the leg hole 6 is formed so as to be inclined downward from the back toward the abdomen, the back side of the bag 8 is lowered when worn, and urine is guided to the rear of the bag 8. Since it becomes easy, it is possible to easily set urine in an appropriate part of the bag body 11 according to the expected posture of the wearer.

また、図７（ｂ）に示すように、本例のレッグホール６はスリット状の開口（線状の開口）として形成されているが、開口形状が横長の矩形又は楕円形その他の横長形状で開口面積がスリットよりも大きい切欠き状の開口として形成してもよい。このように開口面積の大きい切欠き状の開口であれば、着用する際に着用者の脚を通しやすいので着用動作がより楽になるが、反面、気密性は低下する。   In addition, as shown in FIG. 7B, the leg hole 6 of this example is formed as a slit-like opening (linear opening), but the opening shape is a horizontally long rectangle or an ellipse or other horizontally long shape. You may form as a notch-shaped opening whose opening area is larger than a slit. Thus, a notch-shaped opening having a large opening area facilitates the wearing operation because it is easy to pass the wearer's leg when wearing, but the airtightness is lowered.

The front view and the figure (b) which are shown in this figure are the side views.

（３）変形例（図１２乃至図１７）
本例の吸収体製品１ａにおける吸収体４等の構造の変形例について説明する。
図１２及び図１３は、吸収体としてＳＡＰを主成分としたシート状吸収体４を使用した複数種類の変形例を示すものであり、着用者の前後方向に直交する鉛直面を切断面とした袋部８の縦断面図である。本変形例では、２枚のシート状吸収体４が、袋体１１の上部開口１０の近傍において、袋体１１の両側面の各内面に、それぞれ各上縁部を接続されて下方内向きに張り出して設置されている。そして、シート状吸収体４の下端と袋体１１の底部との間に高さＬの空間が構成され、シート状吸収体４の上方と前記空間とを連通する隙間１２がシート状吸収体４の下端に形成されている。このような空間は、ＳＡＰを主成分とする吸収体にとって非常に重要な役割を演ずる。即ち、ＳＡＰの膨潤吸収開始にはある設定時間がかかるため、一時的に尿を貯留しておく機能が必要である。これを本発明者等はトラップ機能と称するが、この空間はそのような機能を発揮させるためのものである。なお、シート状吸収体４の下端と袋体１１の底部との間の空間の高さＬは、同空間内でのトラップ機能さらには尿の移動や便の収容といった目的をより有効に達成するためには、例えば５ｍｍ以上とすることが好ましい。より好ましくは１０ｍｍ〜３０ｍｍである。 (3) Modification (FIGS. 12 to 17)
A modification of the structure of the absorbent body 4 and the like in the absorbent body product 1a of this example will be described.
FIG.12 and FIG.13 shows the multiple types of modification which uses the sheet-like absorber 4 which has SAP as a main component as an absorber, The perpendicular surface orthogonal to a wearer's front-back direction was made into the cut surface. 3 is a longitudinal sectional view of a bag portion 8. FIG. In this modification, the two sheet-like absorbent bodies 4 are connected to the inner surfaces of both side surfaces of the bag body 11 in the vicinity of the upper opening 10 of the bag body 11 and the respective upper edges are connected downward inward. It is installed overhanging. A space having a height L is formed between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11, and a gap 12 that connects the space above the sheet-like absorbent body 4 and the space is formed in the sheet-like absorbent body 4. Is formed at the lower end. Such a space plays a very important role for an absorber composed mainly of SAP. That is, since it takes a set time to start the swelling absorption of SAP, a function of temporarily storing urine is required. The present inventors refer to this as a trap function, but this space is for exhibiting such a function. Note that the height L of the space between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11 more effectively achieves the trap function in the same space, as well as the purpose of moving urine and storing stool. For this purpose, for example, it is preferably 5 mm or more. More preferably, it is 10 mm-30 mm.

図１２（ａ）の変形例によれば、左右方向の寸法の異なる２枚のシート状吸収体４が、斜め下方に延設され、両下端部が隙間１２をおいて重ねられている。図１２（ｂ）の変形例によれば、左右方向の寸法が同一である２枚のシート状吸収体４が、斜め下方に延設され、両下端部が隙間１２をおいて対向するように配置されている。図１３（ａ）の変形例によれば、折りたたまれて断面略三角形とされた２枚のシート状吸収体４が、斜め下方に延設され、両下端部が隙間１２をおいて対向するように設置されている。図１３（ｂ）の変形例によれば、袋体１１の内面に沿った湾曲形状（断面略Ｕ字状）とされた１枚のシート状吸収体４が、袋体１１の内面に沿って配置されており、その下端部には図１３（ｃ）に示すように略長楕円形のような切欠き状の隙間１２が設けられている。   According to the modification of FIG. 12A, two sheet-like absorbers 4 having different left and right dimensions are extended obliquely downward, and both lower end portions are overlapped with a gap 12 therebetween. According to the modified example of FIG. 12B, the two sheet-like absorbers 4 having the same horizontal dimension are extended obliquely downward so that both lower end portions face each other with a gap 12 therebetween. Has been placed. According to the modification of FIG. 13A, the two sheet-like absorbers 4 that are folded and have a substantially triangular cross section are extended obliquely downward so that both lower ends face each other with a gap 12 therebetween. Is installed. According to the modification of FIG. 13B, a single sheet-like absorbent body 4 having a curved shape (substantially U-shaped cross section) along the inner surface of the bag body 11 extends along the inner surface of the bag body 11. As shown in FIG. 13C, a notch-like gap 12 having a substantially elliptical shape is provided at the lower end thereof.

図１２及び図１３に示した各変形例によれば、尿はシート状吸収体４に沿って下方に流れ、隙間１２から下方の空間内に落ち、さらに袋体１１内の下方の空間内を前後に自由に移動して袋体１１内にあるシート状吸収体４の全量を効率的に使用して吸収される。また、便をシート状吸収体４の隙間から下方の空間内に落下させることにより、着用者の体表面から離して保持する効果もある。なお、シート状吸収体４は、表面側から吸収するタイプと裏面側から吸収するタイプのいずれでもよい。   According to each modification shown in FIGS. 12 and 13, urine flows downward along the sheet-like absorbent body 4, falls into the lower space from the gap 12, and further passes through the lower space in the bag body 11. The sheet-shaped absorbent body 4 is freely moved back and forth to be absorbed efficiently by using the entire amount of the sheet-like absorbent body 4 in the bag body 11. Moreover, there exists an effect hold | maintained away from a wearer's body surface by dropping a stool in the space below from the clearance gap between the sheet-like absorbers 4. FIG. The sheet-like absorber 4 may be either a type that absorbs from the front side or a type that absorbs from the back side.

図１４及び図１５は、吸収体４と袋体１１の間に液ガイドシート１３等を設けた複数種類の変形例を示すものである。図１４（ａ），図１４（ｃ），図１５（ａ）は着用者の前後方向に直交する鉛直面を切断面とした袋部８の縦断面図であり、図１４（ｂ）は図１４（ａ）の部分拡大図、図１５（ｂ）は図１５（ａ）の展開状態を示す図である。   14 and 15 show a plurality of types of modifications in which a liquid guide sheet 13 or the like is provided between the absorbent body 4 and the bag body 11. 14 (a), 14 (c), and 15 (a) are longitudinal sectional views of the bag portion 8 with a vertical plane orthogonal to the wearer's front-rear direction as a cut surface, and FIG. 14 (b) is a diagram. 14 (a) is a partially enlarged view, and FIG. 15 (b) is a view showing a developed state of FIG. 15 (a).

図１４（ａ）及び（ｂ）に示す変形例によれば、袋体１１の底部の内面に沿った形状の吸収体４と該袋体１１の底部との間に液ガイドシート１３が配置されている。本変形例の吸収体４は、図１４（ｂ）に示すように、パルプとＳＡＰの混合体マット１４にトップシート１５が貼付された吸収体４であり、液ガイドシート１３は親水性不織布、例えばＴＣＦ等からなる。図１４（ｃ）に示す変形例は、吸収体がシート状吸収体４であり、シート状吸収体４と袋体１１の間に液ガイドシート１３がある。また、シート状吸収体４の両側縁が袋体１１の内方に折り返された庇部１６とされており、袋部８内に収納された体液が外部へ漏出しにくくなっている。これらの変形例によれば、袋部８の内部に排出された着用者の尿が、液ガイドシート１３によって袋体１１と吸収体４の間に導かれて拡散、移動し、効果的に吸収される効果が得られる。   According to the modification shown in FIGS. 14A and 14B, the liquid guide sheet 13 is disposed between the absorbent body 4 having a shape along the inner surface of the bottom portion of the bag body 11 and the bottom portion of the bag body 11. ing. As shown in FIG. 14B, the absorbent body 4 of the present modification is an absorbent body 4 in which a top sheet 15 is attached to a mixture mat 14 of pulp and SAP, and the liquid guide sheet 13 is a hydrophilic nonwoven fabric, For example, it consists of TCF or the like. In the modification shown in FIG. 14C, the absorbent body is the sheet-like absorbent body 4, and the liquid guide sheet 13 is provided between the sheet-like absorbent body 4 and the bag body 11. Further, both side edges of the sheet-like absorbent body 4 are flanges 16 that are folded back inward of the bag body 11, so that the body fluid stored in the bag section 8 is difficult to leak out. According to these modified examples, the wearer's urine discharged into the bag portion 8 is guided between the bag body 11 and the absorbent body 4 by the liquid guide sheet 13 to diffuse, move, and effectively absorb. Effect is obtained.

図１５（ａ）及び（ｂ）に示す変形例によれば、２枚のシート状吸収体４，４が、袋体１１の両側面の内面に設けられ、袋体１１の底部に沿って前後方向に連続する隙間を空けて配置されている。シート状吸収体４と袋体１１との間には液ガイドシート１３が設けられ、液ガイドシート１３とシート状吸収体４との間には開口フィルム等のスペーサ部材１７が設けられている。本変形例によれば、袋体１１と吸収体４の間の空間がスペーサ部材１７によって広げられ、液の移動がより容易になるので、液ガイドシート１３による尿の拡散、移動作用がより促進され、袋体１１内の吸収体４の全量を一層効率的に利用して尿を吸収させることができる。   According to the modification shown in FIGS. 15A and 15B, the two sheet-like absorbers 4, 4 are provided on the inner surfaces of both side surfaces of the bag body 11, and are moved back and forth along the bottom of the bag body 11. It is arranged with a gap continuous in the direction. A liquid guide sheet 13 is provided between the sheet-like absorbent body 4 and the bag body 11, and a spacer member 17 such as an opening film is provided between the liquid guide sheet 13 and the sheet-like absorbent body 4. According to this modification, the space between the bag 11 and the absorber 4 is widened by the spacer member 17, and the movement of the liquid becomes easier, so that the urine diffusion and movement action by the liquid guide sheet 13 is further promoted. In addition, urine can be absorbed using the entire amount of the absorbent body 4 in the bag body 11 more efficiently.

図１６及び図１７は、袋体１１内の前部及び後部における吸収体４の配置等の変形例を示すものであり、各分図（ａ）は着用者の前後方向に直交する鉛直面を切断面とした袋部８の縦断面図であり、各分図（ｂ）は前部における吸収体４の平面図、各分図（ｃ）は後部における吸収体４の平面図である。   FIG.16 and FIG.17 shows modifications, such as arrangement | positioning of the absorber 4 in the front part in the bag body 11, and a rear part, and each fraction (a) shows the perpendicular surface orthogonal to a wearer's front-back direction. It is the longitudinal cross-sectional view of the bag part 8 made into the cut surface, each division figure (b) is a top view of the absorber 4 in a front part, and each division figure (c) is a top view of the absorber 4 in a rear part.

図１６に示す変形例によれば、吸収体４は袋体１１の内面に沿ってＶ字型に湾曲して配置されており、前部には孔やスリットはないが、後部には便を下方に落下させるためのスリット状の隙間１２が形成されている。図１７に示す変形例によれば、２枚の平面状の吸収体４，４が袋体１１の両側部の各内面に沿って間隔をもって配置されており、前部においては両吸収体４は液透過性不織布１８によって連結されており、後部においては便を下方に落下させるために両吸収体４，４の間には隙間１２がそのまま残されている。   According to the modification shown in FIG. 16, the absorbent body 4 is arranged in a V-shape along the inner surface of the bag body 11, and there are no holes or slits in the front part. A slit-like gap 12 for dropping downward is formed. According to the modification shown in FIG. 17, two planar absorbent bodies 4, 4 are arranged at intervals along the inner surfaces of both side portions of the bag body 11. It is connected by a liquid-permeable nonwoven fabric 18, and a gap 12 is left as it is between the absorbent bodies 4, 4 in order to drop feces downward in the rear part.

図１６及び図１７に示す変形例によれば、便は吸収体４の後部の底部に設けられた隙間１２から下方に落下させて吸収体４と袋体１１の間の空間に収納保持することができる。   According to the modification shown in FIGS. 16 and 17, the stool is stored in the space between the absorbent body 4 and the bag body 11 by dropping downward from the gap 12 provided at the bottom of the rear part of the absorbent body 4. Can do.

（４）吸収体製品１ａの取外し方法
本例の吸収体製品１ａを着用者の体から取り外すには、着用動作と逆の動作によって脱ぐこともできるが、レッグホール６の両端を前後両方向に切り開き、着用状態でレッグホール６よりも上の胴体部７と下の袋部８を上下に分離し、袋部８を取り外した後に胴体部７を着用者のウェストから外すこともできる。又は、胴体部７及び袋部８の各前部中央及び後部中央にある接合部分を左右に切り開いて着用者の下半身から取り外すこともできる。 (4) Removal method of absorbent product 1a To remove the absorbent product 1a of this example from the wearer's body, it can be removed by the reverse of the wearing operation, but both ends of the leg hole 6 are opened in both the front and rear directions.

図２５に示すように、不織布２の幅方向に関する両側縁をそれぞれ内方に折り返し、弾性部材５に重ねて不織布２同士を接着する。この部分が、袋体１１の上部開口１０に設けられて上部開口１０の内部に張り出すように形成され袋体１１内から体液が外部へ漏出するのを防ぐ伸縮帯２０となる。   As shown in FIG. 25, both side edges in the width direction of the nonwoven fabric 2 are folded back inward, and the nonwoven fabrics 2 are bonded to each other by overlapping with the elastic member 5. This portion is provided in the upper opening 10 of the bag body 11 and is formed so as to protrude into the upper opening 10, thereby forming an elastic band 20 that prevents body fluid from leaking out of the bag body 11.

図２６に示すように、重ねられた不織布２と液不通過性シート３の幅方向に関する２つの境界部分、すなわち幅方向について不織布２と液不通過性シート３が隣接している所定方向に連続する２つの領域に、複数本の弾性部材５を所定方向に伸張させた状態でそれぞれ配置する。不織布２と液不通過性シート３の境界部分には後工程でレッグホール６を形成するので、弾性部材５を切断せずにレッグホール６を形成する余地を設けるとともに、レッグホール６の両側に弾性部材５が配置されるように、第１実施形態と同様、弾性部材５の間隔の中に相対的に広い間隔ａとなる部分を設ける。   As shown in FIG. 26, two boundary portions in the width direction of the nonwoven fabric 2 and the liquid impermeable sheet 3 that are stacked, that is, the nonwoven fabric 2 and the liquid impermeable sheet 3 are adjacent to each other in the width direction. A plurality of elastic members 5 are respectively arranged in two regions that are stretched in a predetermined direction. Since a leg hole 6 is formed in the boundary portion between the nonwoven fabric 2 and the liquid impermeable sheet 3 in a later step, there is room for forming the leg hole 6 without cutting the elastic member 5 and both sides of the leg hole 6 are provided. As in the first embodiment, a portion having a relatively wide interval a is provided in the interval of the elastic member 5 so that the elastic member 5 is arranged.

図２７に示すように、前記不織布２の幅方向の両側縁をそれぞれ内方に折り返し、前記弾性部材５の弾性部材５を挟んで接着する。   As shown in FIG. 27, both side edges in the width direction of the nonwoven fabric 2 are folded inward, and the elastic members 5 of the elastic members 5 are sandwiched and bonded.

図２８に示すように、吸収体４の両側方にある２つの境界領域において、弾性部材５の間隔が広めのａとされた位置に、所定方向に沿ってレッグホール６をスリット状の開口として貫通して形成する。これによって、レッグホール６の上下に弾性部材５が配置されることとなり、着用時にはレッグホール６の全周が着用者の脚の周囲に弾性をもって密着するので吸収体製品１ｂとしての密閉状態を保つことができる。また、図２８（ａ）中に示したように、レッグホール６の両端に、レッグホール６をなすスリット状の裂け目がさらに進行するのを防止するために、スリットと直交する方向の短いストップカット２１を設ける。   As shown in FIG. 28, in the two boundary regions on both sides of the absorber 4, the leg hole 6 is formed as a slit-shaped opening along a predetermined direction at a position where the distance between the elastic members 5 is a wide. Form through. Thereby, the elastic member 5 will be arrange | positioned at the upper and lower sides of the leg hole 6, and since the whole periphery of the leg hole 6 adheres elastically to the circumference | surroundings of a wearer's leg at the time of wear, the sealed state as the absorber product 1b is maintained. be able to. Further, as shown in FIG. 28 (a), in order to prevent the slit-shaped rift forming the leg hole 6 from proceeding further at both ends of the leg hole 6, a short stop cut in the direction perpendicular to the slit is performed. 21 is provided.

図２９に示すように、吸収体４の幅方向の中央を通り、所定方向に平行な中心線に沿って、吸収体４が２つ折りになるとともに不織布２の幅方向の両側縁が重なるように、全体を折り返す。   As shown in FIG. 29, the absorbent body 4 is folded in two along the center line parallel to the predetermined direction through the center in the width direction of the absorbent body 4 so that both side edges in the width direction of the nonwoven fabric 2 overlap. Wrap the whole thing.

図３０（ａ）において鎖線で示すように、所定方向と直交する方向に沿って吸収体４と吸収体４の間をシールカットすることにより、図３０（ｂ）に示すような吸収体製品１ｂに分離される。なお、図３０（ｂ）に示す吸収体製品１ｂの形状は、図３０（ａ）に示すように所定方向について張力を与えて伸張されている状態でシールカットした瞬間の個々の製品を表すものであり、実際にはシールカットされて個々の製品に分離された瞬間に、弾性部材５の縮退によって図３１（ａ）に示すようにレッグホール６よりも上方の胴体部７が縮み、レッグホール６よりも下方の袋部８が相対的に前後に張り出した外形になる。   As shown by a chain line in FIG. 30 (a), an absorbent product 1b as shown in FIG. 30 (b) is obtained by sealing and cutting between the absorbent body 4 and the absorbent body 4 along a direction orthogonal to the predetermined direction. Separated. In addition, the shape of the absorbent product 1b shown in FIG. 30 (b) represents individual products at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 30 (a). In fact, at the moment when the seal is cut and separated into individual products, the body portion 7 above the leg hole 6 is contracted as shown in FIG. The bag part 8 below 6 has an outer shape that projects relatively forward and backward.

（２）構造（図３１乃至図３３）
次に、以上の工程によって得られた吸収体製品１ｂの構造を図３１乃至図３３を参照して説明する。図３１及び図３２は本例の吸収体製品１ｂを人体に装着したように広げた際の形態を示している。図３３は本例の吸収体製品１ｂの袋体１１の模式的な正断面図である。 (2) Structure (FIGS. 31 to 33)
Next, the structure of the absorbent product 1b obtained by the above steps will be described with reference to FIGS. FIG.31 and FIG.32 has shown the form at the time of extending the absorber product 1b of this example so that it might mount | wear with a human body. FIG. 33 is a schematic front sectional view of the bag 11 of the absorbent product 1b of this example.

本例の吸収体製品１ｂは、図８及び図９を参照して説明した第１実施形態の吸収体製品１ａと同様の構造を有する他、図３２及び図３３に示すように、両側面から内側に向かって張り出す伸縮帯を備えている。この伸縮帯は袋体１１の両側面の各内面から突出する不織布２からなる脚部と、脚部の先端に設けられた弾性部材５とからなる伸縮帯２０を備える。この伸縮帯２０は、袋体１１の上部開口１０の内側面に内側上方に向けて延設され、着用者の体表面に沿って接触するので、袋体１１内に排出されて吸収体４に捕集された体液が重力によって再び着用者の体表面に流出し、外部へ漏出するのを防ぐことができる。また、本例の吸収体製品１ｂは、袋体１１の上部開口１０の近傍にあるシート状吸収体４の上縁部が、袋体１１の内方に折り返された庇部１６とされているので、外部に漏出しようとする体液が上部開口１０の近傍で庇部１６によって吸収され、外部へ漏出するのを防止することができる。   The absorbent product 1b of this example has the same structure as the absorbent product 1a of the first embodiment described with reference to FIG. 8 and FIG. 9, and as shown in FIG. 32 and FIG. It has an elastic band that protrudes inward. This stretchable band includes a stretchable band 20 composed of a leg portion made of a nonwoven fabric 2 protruding from the inner surfaces of both sides of the bag 11 and an elastic member 5 provided at the tip of the leg portion. The stretchable band 20 extends inward and upward on the inner side surface of the upper opening 10 of the bag body 11 and contacts along the body surface of the wearer. It is possible to prevent the collected body fluid from flowing out to the wearer's body surface again due to gravity and leaking outside. Further, in the absorbent product 1 b of this example, the upper edge portion of the sheet-like absorbent body 4 in the vicinity of the upper opening 10 of the bag body 11 is a flange portion 16 that is folded inward of the bag body 11. Therefore, it is possible to prevent body fluid that is about to leak to the outside from being absorbed by the heel portion 16 in the vicinity of the upper opening 10 and leaking to the outside.

（３）その他の構造例（図３４乃至図３６）
本例の吸収体製品１ｂは、第１実施形態の吸収体製品１ａに、伸縮帯２０と、吸収体４の庇部１６とを設けたものであるが、伸縮帯２０と庇部１６は、以下に説明するように、それぞれ単独で設けることとしてもよい。 (3) Other structural examples (FIGS. 34 to 36)
The absorbent product 1b of the present example is the absorbent product 1a of the first embodiment provided with the stretchable band 20 and the flange part 16 of the absorber 4, but the stretchable band 20 and the flange part 16 are: As described below, each may be provided alone.

すなわち、図３４（ａ）に示すように、袋体１１の内部の底部に吸収体４（必ずしもシート状吸収体でなくてもよい）を設け、袋体１１の上部開口１０に近い内側面に、不織布２からなる脚部と弾性部材５からなる一対の伸縮帯２０を内側下方に向けて設ければ、伸縮帯２０の下方には袋体１１の内面との間にポケット状の受容空間が形成される。従って、着用者が***を変更し、袋体１１内の尿が上部開口１０から外へ逆流しようとしても、尿は受容空間に入って直接外に流出することはない。   That is, as shown in FIG. 34 (a), the absorbent body 4 (not necessarily a sheet-like absorbent body) is provided at the bottom inside the bag body 11, and the bag body 11 has an inner surface near the upper opening 10. If a pair of elastic bands 20 made of the nonwoven fabric 2 and the elastic member 5 are provided facing inward and downward, a pocket-shaped receiving space is formed between the inner surface of the bag body 11 below the elastic band 20. It is formed. Therefore, even if the wearer changes his / her posture and the urine in the bag 11 tries to flow backward from the upper opening 10, the urine does not enter the receiving space and directly flow out.

なお、図３４（ｂ）は、伸縮帯２０を内側上方に向けて設けた構造例であり、前述した図３２及び図３３と同様の構成である。   Note that FIG. 34B is a structural example in which the stretchable band 20 is provided inward and upward, and has the same configuration as that of FIGS. 32 and 33 described above.

図３５（ａ）は、袋体１１の上部開口１０に近いシート状吸収体４の上縁部を内側に折り返して庇部１６とした例を示すものであり、同図（ｂ）はシート状吸収体４の拡大図、図３６はシート状吸収体４の拡大断面図である。図３６に示すように、不織布２の片面にＰＥＴウェブ２２を設け、その上にＳＡＰ２３を配置してなるシート状吸収体４を、図３５（ａ）乃至（ｂ）に示すように、ＳＡＰが内側となって内面が吸収面となるように袋体１１内に配置し、その上縁部を内側に折り返して庇部１６とすれば、庇部１６の下側には袋体１１との間にポケット状の空間ができる。従って、袋体１１の内部に排出された尿は袋体１１の底部又は側面付近において吸収されるし、着用者が***を変更して袋体１１内の尿が上部開口１０から外へ逆流しようとした場合にも、尿はポケット状の空間に流れ込んで庇部１６の下面側で吸収されるので、外に漏出することはない。   FIG. 35A shows an example in which the upper edge portion of the sheet-like absorbent body 4 near the upper opening 10 of the bag body 11 is folded inward to form the flange portion 16, and FIG. FIG. 36 is an enlarged cross-sectional view of the sheet-like absorber 4. As shown in FIGS. 35 (a) to 35 (b), as shown in FIGS. 35 (a) to 35 (b), as shown in FIGS. If it arrange | positions in the bag body 11 so that it may become inner side and an inner surface may become an absorption surface and the upper edge part is turned inside, and it is set as the collar part 16, it will be between the bag body 11 on the lower side of the collar part 16 A pocket-shaped space is created. Therefore, the urine discharged into the bag body 11 is absorbed near the bottom or the side surface of the bag body 11, and the wearer changes the posture so that the urine in the bag body 11 flows backward from the upper opening 10 to the outside. Even in this case, urine flows into the pocket-shaped space and is absorbed on the lower surface side of the heel part 16, so that it does not leak out.

３．第３実施形態（図３７〜図４６）：カーブシール＆カット方式
（１）製造方法
図３７に示すように、不織布２を所定方向に連続して供給搬送しながら、所定位置において不織布２の幅方向の中央に、不織布２よりも幅の小さい液不通過性シート３を供給して重ね合せ、連続的に接合して所定方向に連続する帯状の防漏体を形成していく。 3. Third Embodiment (FIGS. 37 to 46): Curve Seal & Cut Method (1) Manufacturing Method As shown in FIG. 37, the width of the nonwoven fabric 2 at a predetermined position while continuously feeding and conveying the nonwoven fabric 2 in a predetermined direction. In the center of the direction, a liquid impermeable sheet 3 having a width smaller than that of the nonwoven fabric 2 is supplied and superposed, and continuously joined to form a strip-shaped leak preventer continuous in a predetermined direction.

図３８に示すように、液不通過性シート３の幅方向の中央部の上に、液不通過性シート３よりも幅の小さい複数の吸収体４を、所定方向について適宜間隔をおいて配置していく。   As shown in FIG. 38, a plurality of absorbent bodies 4 having a width smaller than that of the liquid-impermeable sheet 3 are arranged at appropriate intervals in a predetermined direction on the central portion in the width direction of the liquid-impermeable sheet 3. I will do it.

図３９に示すように、重ねられた不織布２と液不通過性シート３の幅方向に関する２つの境界部分、すなわち幅方向について不織布２と液不通過性シート３が隣接している所定方向に連続する２つの領域に、複数本の弾性部材５を所定方向に伸張させた状態でそれぞれ配置する。不織布２と液不通過性シート３の境界部分には後工程でレッグホール６を形成するので、弾性部材５を切断せずにレッグホール６を形成する余地を設けるとともに、レッグホール６の両側に弾性部材５が配置されるように、第１実施形態と同様、弾性部材５の間隔の中に相対的に広い間隔ａとなる部分を設ける。   As shown in FIG. 39, the two nonwoven fabrics 2 and the liquid impervious sheet 3 overlapped in the width direction, that is, in the predetermined direction in which the nonwoven fabric 2 and the liquid impermeable sheet 3 are adjacent in the width direction. A plurality of elastic members 5 are respectively arranged in two regions that are stretched in a predetermined direction. Since a leg hole 6 is formed in the boundary portion between the nonwoven fabric 2 and the liquid impermeable sheet 3 in a later step, there is room for forming the leg hole 6 without cutting the elastic member 5 and both sides of the leg hole 6 are provided. As in the first embodiment, a portion having a relatively wide interval a is provided in the interval of the elastic member 5 so that the elastic member 5 is arranged.

図４０に示すように、前記不織布２の幅方向の両側縁をそれぞれ内方に折り返し、前記弾性部材５の弾性部材５を挟んで接着する。   As shown in FIG. 40, both side edges in the width direction of the nonwoven fabric 2 are folded back inward, and are bonded with the elastic member 5 of the elastic member 5 interposed therebetween.

図４１に示すように、２つの境界部分よりも内側又は折り返した不織布２の両側縁よりも内側の部分を、所定方向に並ぶ複数の吸収体４の間を左右から交互に通過する連続したＳ字状のカットラインで切断する（図中破線で示す）。本工程によって、吸収体製品１ｂを構成する部材乃至材料は、所定方向について右側にある右部分と左側にある左部分とに分かれる。   As shown in FIG. 41, continuous S that alternately passes from the left and right between the plurality of absorbent bodies 4 arranged in a predetermined direction through the inner side of the two boundary portions or the inner side of the folded back nonwoven fabric 2. Cut along a letter-shaped cut line (indicated by a broken line in the figure). By this step, the member or material constituting the absorbent product 1b is divided into a right part on the right side and a left part on the left side in a predetermined direction.

図４２に示すように、切断された右部分と左部分の一方を裏返してカットラインが一致するように、所定方向にずらして他方の上に重ね合わせる。図示の例では、左部分を右部分の上に位相が一致するように重ねている。そして、連続Ｓ字状のカットラインに沿って連続的にシールする。   As shown in FIG. 42, one of the cut right part and the left part is turned over and shifted in a predetermined direction so as to overlap each other so that the cut lines match. In the illustrated example, the left part is overlaid on the right part so that the phases match. And it seals continuously along a continuous S-shaped cut line.

図４３に示すように、吸収体４と境界領域の間であって弾性部材５がない位置に、前記所定方向に沿ってレッグホール６を貫通して形成する。なお、レッグホール６の両端にはストップカット２１を設ける。   As shown in FIG. 43, a leg hole 6 is formed through the predetermined direction at a position between the absorber 4 and the boundary region and without the elastic member 5. Note that stop cuts 21 are provided at both ends of the leg hole 6.

図４４（ａ）において鎖線で示すように、所定方向と直交する方向に沿って吸収体４と吸収体４の間をシールカットすることにより、図４４（ｂ）に示すような吸収体製品１ｃに分離される。なお、図４４（ｂ）に示す吸収体製品１ｃの形状は、図４４（ａ）に示すように所定方向について張力を与えて伸張されている状態でシールカットした瞬間の個々の製品を表すものであり、実際にはシールカットされて個々の製品に分離された瞬間に、弾性部材５の縮退によって図４５（ａ）に示すように上方の胴体部７が縮み、レッグホール６よりも下方の袋部８の上部が縮まって相対的に下部が前後に張り出した外形になる。   As shown by a chain line in FIG. 44 (a), the absorbent product 1c as shown in FIG. 44 (b) is cut by sealing between the absorber 4 and the absorbent body 4 along a direction orthogonal to the predetermined direction. Separated. The shape of the absorbent product 1c shown in FIG. 44 (b) represents an individual product at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 44 (a). In fact, at the moment when the seal is cut and separated into individual products, the upper body portion 7 is contracted as shown in FIG. The upper part of the bag part 8 shrinks, and it becomes the external shape where the lower part overhangs back and forth.

このように、本例の吸収体製品１ｃの製造方法によれば、所定方向に連続する帯状の不織布２及び液不通過性シート３を重ねつつ所定方向に搬送しながら、その上に吸収体４を配置していき、さらに同方向に伸張させた弾性部材５を吸収体４の両側に配置して不織布２の両側縁を折り重ねて接着し、さらに所定方向に並ぶ吸収体４の間を左右から交互に連続Ｓ字状にカットして右部分と左部分に切断し、一方を裏返して他方に一致させて重ね、カットラインに沿って連続的にシールしてから吸収体４と吸収体４の間でシールカットして個々の吸収体製品１ｃに分離していくので、本例の吸収体製品１ｃを容易かつ確実に大量生産できるという効果が得られる。   Thus, according to the manufacturing method of the absorbent product 1c of this example, the belt-shaped nonwoven fabric 2 and the liquid-impermeable sheet 3 continuous in a predetermined direction are stacked and conveyed in a predetermined direction while being stacked thereon. The elastic members 5 further extended in the same direction are arranged on both sides of the absorbent body 4 and the both side edges of the nonwoven fabric 2 are folded and bonded together, and further, the left and right sides of the absorbent bodies 4 arranged in a predetermined direction are left and right. Are alternately cut into continuous S-shapes, cut into right and left portions, one side upside down, overlapped with the other, overlapped, and continuously sealed along the cut line before absorber 4 and absorber 4 Since the absorbent product 1c of this example is easily and surely mass-produced, it is possible to obtain an effect of mass production.

And a third seal portion 25c along a predetermined direction that continues to a position corresponding to the midway portion of the adjacent absorber 4 along the portion (20), and each seal portion 25a, 25b, 25c is continuous. As a whole, the shape is such that two L-shapes having substantially the same shape are combined with the object to be rotated.

そして、吸収体４の幅方向の中央を通り所定方向に平行な中心線に沿って、吸収体４が２つ折りになるとともに胴体部７の幅方向の両側縁が重なるように全体を折り返す。   Then, along the center line passing through the center of the absorbent body 4 in the width direction and parallel to the predetermined direction, the absorbent body 4 is folded in two and the whole body portion 7 is folded back so that both side edges in the width direction overlap.

図５８（ａ）において鎖線で示すように、所定方向と直交する方向に沿って吸収体４と吸収体４の間で第２シール部２５ｂを通過してシールカットすることにより、図５８（ｂ）に示すような吸収体製品１ｄに分離される。なお、図５８（ｂ）に示す吸収体製品１ｄの形状は、図５８（ａ）に示すように所定方向について張力を与えて伸張されている状態でシールカットした瞬間の個々の製品を表すものであり、実際にはシールカットされて個々の製品に分離された瞬間に、弾性部材５の縮退によって図５９（ａ）に示すように上方の胴体部７が縮み、レッグホール６よりも下方の袋部８の上部が縮まって相対的に下部が前後に張り出した外形になる。   As shown by a chain line in FIG. 58 (a), by passing through the second seal portion 25b between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction, and performing a seal cut, FIG. The absorbent product 1d as shown in FIG. The shape of the absorbent product 1d shown in FIG. 58 (b) represents an individual product at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 58 (a). In fact, at the moment when the seal is cut and separated into individual products, the upper body portion 7 is contracted as shown in FIG. The upper part of the bag part 8 shrinks, and it becomes the external shape where the lower part overhangs back and forth.

本例の吸収体製品１ｄの製造方法によれば、弾性部材５を不織布２で挟んだ所定方向に長い胴体部７となる部分と、不織布２と液不通過性シート３と吸収体４からなり液逆流防止用の伸縮帯２０を有する所定方向に長い袋部８となる部分を、それぞれあらかじめ製造しておく。そして、間隔をおいた２つの胴体部７となる部分の上に袋部８をとなる部分を重ねて載置し、重なり部分で略クランク状にシールしてレッグホール６を形成する。そして、所定方向に平行な中心線に沿って全体を２つ折りにし、所定方向と直交する方向に沿って吸収体４と吸収体４の間のシール部分を通ってシールカットし、個々の吸収体製品１ｄに分離する。本例によれば、このような連続的で簡易な製法により、特に伸縮帯付きの袋部８が着用者の前方よりも後方において広く開口している形態の吸収体製品１ｄを容易かつ確実に大量生産できるという効果が得られる。   According to the manufacturing method of the absorbent product 1d of this example, the elastic member 5 is sandwiched between the nonwoven fabrics 2 and includes a portion that becomes the body portion 7 that is long in a predetermined direction, the nonwoven fabric 2, the liquid-impermeable sheet 3, and the absorber 4. Each of the portions that become the long bag portion 8 in the predetermined direction having the elastic band 20 for preventing the liquid back flow is manufactured in advance. And the part which becomes the bag part 8 is mounted on the part which becomes the two trunk | drums 7 with the space | interval, and the leg hole 6 is formed by sealing in a substantially crank shape in the overlapping part. Then, the whole is folded in half along a center line parallel to a predetermined direction, and a seal is cut through a seal portion between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction. Separated into product 1d. According to this example, by such a continuous and simple manufacturing method, it is possible to easily and reliably produce the absorbent product 1d in a form in which the bag portion 8 with the stretchable band is opened wider at the rear than the front of the wearer. The effect of mass production is obtained.

（２）構造（図５９乃至図６５）
次に、以上の工程によって得られた吸収体製品１ｄの構造を図５９（ａ），（ｂ）及び図６０乃至図６５を参照して説明する。これらの図は本例の吸収体製品１ｄを人体に装着したように広げた際の形態を示している。 (2) Structure (FIGS. 59 to 65)
Next, the structure of the absorbent product 1d obtained by the above steps will be described with reference to FIGS. 59 (a) and 59 (b) and FIGS. These figures show the form when the absorbent product 1d of the present example is spread as if it is worn on a human body.

本例の吸収体製品１ｄは、図７（ｃ）乃至（ｅ）を参照して説明した第１実施形態の吸収体製品１ａと同様の基本構造を有するが、図５９（ａ）及び図６０、図６１、図６３、図６４に示すように、袋部の上縁に内側に張り出すように備えられた伸縮帯２０は、袋部８の前方では両側からせり出し、狭い幅になっている。しかも胴体部７に接着されていないために、胴体部の伸縮の影響を受けない。吸収体４が入った袋部８の上部開口１０は着用者の前側にいくほど狭くなり、閉鎖状態となって尿用のポケットを構成している。一方後方では、図５９（ａ）及び図６２、図６５に示すように、袋部８の後方の伸縮帯２０は、その外側で胴体部７に接着されているため、着用時には拡幅され、袋部８の上部開口１０は着用者の後側では広く開口しており、便の通過スペースが確保されている。   The absorbent product 1d of the present example has the same basic structure as the absorbent product 1a of the first embodiment described with reference to FIGS. 7C to 7E, but FIG. 59A and FIG. 61, 63, and 64, the elastic band 20 provided so as to project inward from the upper edge of the bag portion protrudes from both sides in front of the bag portion 8 and has a narrow width. . And since it is not adhere | attached on the trunk | drum 7, it is not influenced by the expansion-contraction of a trunk | drum. The upper opening 10 of the bag portion 8 containing the absorbent body 4 becomes narrower toward the front side of the wearer and is closed to form a urine pocket. On the other hand, as shown in FIG. 59 (a), FIG. 62, and FIG. 65, the elastic band 20 behind the bag portion 8 is bonded to the body portion 7 on the outer side. The upper opening 10 of the portion 8 is wide open on the rear side of the wearer, and a stool passing space is secured.

このため、本例の吸収体製品１ｄによれば、着用者の前方（腹側）に排出される尿は、上部開口１０が狭く伸縮帯２０が設けられた袋部８の前方部分からは漏れにくく、また着用者の後方（背側）に排出される便は上部開口１０が広い袋部８の後方部分に収納される。   For this reason, according to the absorbent product 1d of this example, urine discharged to the front (abdominal side) of the wearer leaks from the front portion of the bag portion 8 in which the upper opening 10 is narrow and the elastic band 20 is provided. The stool that is difficult to be discharged to the back (back side) of the wearer is stored in the back portion of the bag portion 8 having a wide upper opening 10.

また、レッグホール６の上縁には胴体部７の弾性部材５があり、下縁には袋部８の伸縮帯２０の弾性部材５があり、着用者の脚の周面とレッグホール６の周縁との間には高い密着性が得られ、液漏れや臭い漏れが防止される。   In addition, the upper edge of the leg hole 6 has an elastic member 5 of the body part 7, and the lower edge has an elastic member 5 of an elastic band 20 of the bag part 8, and the circumferential surface of the wearer's leg and the leg hole 6 High adhesion is obtained between the periphery and liquid leakage and odor leakage are prevented.

以上説明したように、本発明のいずれの実施形態においても、吸収体４を有する袋部８は、着用者の両脚の間の下半身に上部開口１０を対面させた状態で両脚の間に配置され、着用者が排出した尿等は袋部８の内部に排出されるので、尿等が皮膚に付着する可能性が低いために皮膚がかぶれにくく、装着感も良好である。また尿が袋体１１の内部で移動することにより内部の吸収体４を効率的に使用することができる。これに対し、従来の吸収体製品は、吸収体を肌に密着させて配置し、肌と吸収体の間に広がる体液（尿）を、これと密着する部位にある吸収体だけで吸収するものであったが、本例の吸収体製品１ｄはこれとは全く異なる構造及び吸収メカニズムを採用する画期的な吸収体製品１ｄである。   As described above, in any of the embodiments of the present invention, the bag portion 8 having the absorber 4 is disposed between both legs with the upper opening 10 facing the lower half of the wearer's legs. Since the urine discharged by the wearer is discharged into the bag portion 8, the possibility of the urine etc. adhering to the skin is low, so that the skin is hardly irritated and the wearing feeling is good. Moreover, when the urine moves inside the bag 11, the internal absorber 4 can be used efficiently. In contrast, conventional absorbent products are arranged with the absorbent body in close contact with the skin, and the body fluid (urine) that spreads between the skin and the absorbent body is absorbed only by the absorbent body that is in close contact with the skin. However, the absorbent product 1d of this example is an epoch-making absorbent product 1d that adopts a completely different structure and absorption mechanism.

また、本発明のいずれの実施形態においても、連続帯状の材料を所定方向に搬送しつつ重ねたり折り返したりしながら最終的にはシールカットして個々の吸収体製品に分離して完成していくという連続的で簡易な製法により、上述した画期的な吸収メカニズムを有する本例の吸収体製品を、容易かつ確実に大量生産できるという効果が得られる。   In any of the embodiments of the present invention, the continuous band-shaped material is transported in a predetermined direction while being overlapped or folded, and finally the seal is cut and separated into individual absorber products to be completed. By the continuous and simple production method, the effect that the absorbent product of the present example having the above-described innovative absorption mechanism can be easily and reliably mass-produced is obtained.
