Description

本発明は、横向きに寝た状態での腰脇部分からの横漏れを広範囲で確実に防止できる使い捨てパンツ型おむつに関する。   The present invention relates to a disposable pants-type diaper that can reliably prevent side leakage from the waist-side portion in a state of lying sideways over a wide range.

従来、使い捨ておむつと併用する使い捨て補助吸収具として、使い捨ておむつの前腹部または後背部の左右のサイドフラップに別体の補助吸収具をそれぞれ面ファスナーで着脱自在に固定するものがある（例えば、特許文献１参照）。   Conventionally, as a disposable auxiliary absorbent used in combination with a disposable diaper, there is one in which separate auxiliary absorbents are detachably fixed to the left and right side flaps of a disposable diaper with a hook-and-loop fastener respectively (for example, patents) Reference 1).

また、使い捨ておむつと共に着用される使い捨て補助吸収具として、中央縦割りの半パンツ状物がある（例えば、特許文献２参照）。   Moreover, as a disposable auxiliary | assistant absorbent tool worn with a disposable diaper, there exists a half pants-like thing of the center vertical division (for example, refer patent document 2).

さらに、使い捨てアンダーガーメントとして、股用吸収体が配置された股部の左右に、前腹部と後背部の左半分と右半分がそれぞれ形成されて、左右の前腹部の前端同士と後背部の後端同士とが接合されるとともに、この各半分の前腹部と後背部とに跨ってスリット状の脚穴部がそれぞれ形成されたものがある（例えば、特許文献３参照）。
特開２００１−３５３１８０号公報 特開２００１−３４０３７０号公報 特開２００２−２４２００１号公報 Furthermore, as a disposable undergarment, the left and right halves of the front and back abdomen are formed on the left and right sides of the crotch where the absorbent body for crotch is arranged, respectively. In some cases, the ends are joined to each other, and slit-like leg hole portions are formed across the front and back portions of each half (see, for example, Patent Document 3).

しかしながら、特許文献１では、展開可能な使い捨ておむつを対象としており、使い捨ておむつを展開状態として、前腹部または後背部の左右のサイドフラップに別体の補助吸収具をそれぞれ正規の位置に固定する必要があるから、着用者や介護者にとって固定作業に手間がかかるという問題がある。   However, in patent document 1, it is aimed at the disposable diaper which can be developed, and it is necessary to fix a separate auxiliary absorber in a regular position to the left and right side flaps of the front abdominal part or the back part with the disposable diaper in an expanded state. Therefore, there is a problem that it takes time and labor for the wearer and the caregiver to fix.

また、ファスニングテープ等で使い捨ておむつを組み立てて着用するから（開閉式テープ型）、着用時の快適性に欠けるという問題がある。   Moreover, since a disposable diaper is assembled and worn with a fastening tape or the like (open / closed tape type), there is a problem of lack of comfort during wearing.

さらに、前腹部または後背部の左右のサイドフラップに補助吸収具を面ファスナーで着脱自在に固定するだけであるから、着用者の寝返り等の動作により外れて、漏れにつながりやすいという問題がある。   Furthermore, since the auxiliary absorbent is simply fixed to the left and right side flaps of the front abdomen or the back using a hook-and-loop fastener, it may be detached due to the wearer's turning operation and the like, leading to leakage.

特許文献２では、中央縦割りの半パンツ状物である使い捨て補助吸収具を着用した上に使い捨ておむつを重ねて着用する必要があるから、着用者や介護者にとって着用作業に手間がかかるという問題がある。   In Patent Document 2, since it is necessary to wear a disposable diaper on top of a disposable auxiliary absorbent device that is a vertically split half-pants, it is troublesome for the wearer and caregiver to wear the work. There is.

また、補助吸収具と使い捨ておむつを２重に着用するから、着用時の快適性に欠けるという問題がある。   Moreover, since an auxiliary | assistant absorber and a disposable diaper are worn twice, there exists a problem of lacking in the comfort at the time of wear.

さらに、補助吸収具は、着用者の左右のいずれか片方しかカバーできないので、例えば下向きとなる左側をカバーした状態で、右側が下向きとなるように着用者が寝返ったような場合には、腰脇部分からの横漏れを広範囲で確実に防止できないという問題がある。   Further, since the auxiliary absorbent device can cover only one of the left and right sides of the wearer, for example, when the wearer turns over so that the right side is facing down while covering the left side facing down, There is a problem that side leakage from the side portion cannot be reliably prevented over a wide area.

特許文献３では、弾性伸縮性を有する生地で形成され、股部の左右に形成した前腹部と後背部の左半分と右半分とを、前端同士と後端同士とを接合してなる使い捨てアンダーガーメントが開示されているが、各半分の前腹部と後背部とに跨ってスリット状の脚穴部を形成する構成とすることで、半円状の脚穴部を形成することによる生地の無駄を省くようにしたものであり、横向きに寝た状態での腰脇部分からの横漏れを広範囲で確実に防止できるものではない。   In patent document 3, it is a disposable underwear formed of a cloth having elasticity and stretchability, and formed by joining the front and back ends of the front abdomen and the left and right halves of the back and back of the crotch. Garment is disclosed, but by forming a slit-shaped leg hole across the front and back of each half, the waste of fabric by forming a semi-circular leg hole However, it is not possible to reliably prevent side leakage from the waist-side portion in the state of lying down sideways.

本発明は、上記問題を解消するためになされたもので、従来の補助吸収具のような固定作業が無くて着用作業にも手間がかからず、着用時の快適性が向上して、横向きに寝た状態での腰脇部分からの横漏れを広範囲で確実に防止できる使い捨てパンツ型おむつを提供することを課題とするものである。   The present invention was made in order to solve the above problems, and there is no fixing work like a conventional auxiliary absorber, so that the wearing work does not take time, and the comfort at the time of wearing is improved. It is an object of the present invention to provide a disposable pants-type diaper that can reliably prevent lateral leakage from the waist-side portion in a sleeping state in a wide range.

(Claim 12).

上記股用吸収体の左右位置に、立ち上がりフラップが設けられている構成が好ましい（請求項１３）。   A configuration in which rising flaps are provided at the left and right positions of the crotch absorber is preferable.

請求項１の発明は、前腹部と後背部とに跨る左右の腰脇部分以外の部分で前腹部と後背部とを接合するタイプのパンツ形状に適用するものである。例えば、前腹部を股部とほぼ同幅にするとともに、後背部の両側を広幅にして、この広幅の両側部を前腹部側に廻し込んで接合することにより、前腹部と後背部とに跨る左右の腰脇部分に接合部分を無くすることができる。   The invention of claim 1 is applied to a pant shape of a type in which the front abdomen and the back part are joined at portions other than the left and right waistside parts straddling the front abdomen and the back part. For example, the front abdomen is made approximately the same width as the crotch, and both sides of the back part are widened, and both sides of the wide part are turned to the front part of the abdomen to join the front part and the back part. Joints can be eliminated on the left and right waistside parts.

そして、この接合部分の無い左右の腰脇部分に、腰脇用吸収体をそれぞれ固定配置することにより、着用者の腰脇部分全体を腰脇用吸収体で広範囲にカバーできるから、特許文献１と対比して、前腹部または後背部の左右のサイドフラップに補助吸収具を面ファスナーで着脱自在に固定するのでは無いので、着用者の寝返り等の動作により外れないため、漏れを確実に防止できる。特許文献２と対比して、腰脇用吸収体は、着用者の左右の両方をカバーできるので、例えば下向きとなる左側をカバーした状態で、右側が下向きとなるように着用者が寝返ったような場合でも、腰脇部分からの横漏れを広範囲で確実に防止できるようになる。   Since the waistside absorbent body is fixedly disposed on the left and right waistside parts without the joint part, the entire waistside part of the wearer can be covered with the waistside absorbent body over a wide range. In contrast, the auxiliary absorber is not detachably fixed to the left and right side flaps on the front or back of the abdomen with hook-and-loop fasteners. it can. In contrast to Patent Document 2, the waistside absorbent body can cover both the left and right sides of the wearer, so that, for example, the wearer turned over so that the right side is facing downward while covering the left side facing downward Even in this case, it is possible to reliably prevent side leakage from the waistside part over a wide range.

また、パンツ型おむつとして、腰脇用吸収体を固定配置したから、特許文献１と対比して、展開状態の使い捨ておむつの前腹部または後背部の左右のサイドフラップに別体の補助吸収具をそれぞれ正規の位置に固定する必要がない。特許文献２と対比して、中央縦割りの半パンツ状物である使い捨て補助吸収具を着用した上に使い捨ておむつを重ねて着用する必要がないことから、着用者や介護者にとって固定作業や着用作業に手間がかからなくなる。   Moreover, since the waist-side absorbent body is fixedly disposed as a pant-type diaper, in contrast to Patent Document 1, separate auxiliary absorbent devices are provided on the left and right side flaps of the deployed disposable diaper in the front and back. There is no need to fix each in a normal position. Compared to Patent Document 2, it is not necessary to wear a disposable diaper on top of a disposable auxiliary absorbent that is a half-pants in the middle of the center, so that it is not necessary to wear a disposable diaper on top of it, so that it can be fixed and worn for the wearer and caregiver. Work is not time-consuming.

さらに、パンツ型おむつとして、腰脇用吸収体を固定配置したから、特許文献１と対比して、ファスニングテープ等で使い捨ておむつを組み立てて着用する必要が無い。特許文献２と対比して、補助吸収具と使い捨ておむつを２重に着用する必要が無いことから、着用時の快適性が向上するようになる。   Furthermore, since the waist-side absorber is fixedly arranged as a pants-type diaper, it is not necessary to assemble and wear a disposable diaper with a fastening tape or the like, as compared with Patent Document 1. Compared with Patent Document 2, since it is not necessary to wear the auxiliary absorbent and the disposable diaper twice, the comfort at the time of wearing is improved.

請求項２の発明は、前腹部と後背部の左半分と右半分とを、前端同士と後端同士とを接合するタイプのパンツ形状（例えば特許文献３）に適用するものである。かかるタイプのパンツ形状でも、請求項１の発明と同様に、従来の補助吸収具のような固定作業が無くて着用作業にも手間がかからず、着用時の快適性が向上して、横向きに寝た状態での腰脇部分からの横漏れを広範囲で確実に防止できるという効果を奏することができる。   The invention of claim 2 applies the left half and the right half of the front abdomen and the back part to a pant shape (for example, Patent Document 3) in which the front ends and the rear ends are joined. Even in this type of pants shape, as in the invention of claim 1, there is no fixing work as in the conventional auxiliary absorber, so that the wearing work is not troublesome, the comfort at the time of wearing is improved, and It is possible to produce an effect that side leakage from the waist-side portion in the state of sleeping can be reliably prevented in a wide range.

請求項３の発明は、例えば特許文献３のパンツ形状に加えて、股部も左半分と右半分に形成して、股部同士も接合するとともに、左右の股部に股用吸収体をそれぞれ固定配置したものである。請求項１の発明と同様に、従来の補助吸収具のような固定作業が無くて着用作業にも手間がかからず、着用時の快適性が向上して、横向きに寝た状態での腰脇部分からの横漏れを広範囲で確実に防止できるという効果を奏することができる。   In the invention of claim 3, for example, in addition to the pant shape of Patent Document 3, the crotch part is also formed in the left half and the right half, the crotch parts are joined to each other, and the crotch absorber is respectively provided in the left and right crotch parts It is a fixed arrangement. As in the first aspect of the invention, there is no fixing work as in the conventional auxiliary absorber, and the wearing work does not take time and the comfort during wearing is improved, and the waist in the state of lying down sideways. The effect that side leakage from the side part can be reliably prevented over a wide range can be achieved.

加えて、前腹部と後背部の左半分と右半分との折り返し部分となる股部の中心部分に股用吸収体が存在しないから、折り返しても股部が堅くならないので、着用時の快適性がより向上するとともに、見映えも良好になる。   In addition, since there is no absorber for the crotch at the center of the crotch, which is the folded part between the left and right halves of the front and back, the crotch does not become stiff even when folded, so comfort when worn Is improved and the appearance is also improved.

請求項４のように、ウエスト用弾性糸とボディフィット用弾性糸とレッグ用弾性糸を添設すると、使い捨てパンツ型おむつ全体が着用者の身体にフィットして、着用時の快適性がより向上するようになる。   When the elastic yarn for waist, the elastic yarn for body fitting, and the elastic yarn for leg are attached as in claim 4, the entire disposable pants-type diaper fits the wearer's body, and the comfort during wearing is further improved. To come.

請求項５のように、腰脇吸収体を配置した部位のボディフィット用弾性糸の収縮力を小さく設定すると、ボディフィット用弾性糸の収縮に伴う腰脇用吸収体の撚れを防止できるから、着用者の腰脇に対する腰脇用吸収体の密着性が向上して、腰脇部分からの横漏れをより確実に防止できるようになる。   If the contraction force of the body-fit elastic yarn at the portion where the waist-side absorbent body is disposed is set to be small as in claim 5, it is possible to prevent twisting of the waist-side absorbent body accompanying the contraction of the body-fit elastic yarn. The adhesion of the waist-side absorbent body to the waist side of the wearer is improved, and side leakage from the waist-side portion can be more reliably prevented.

請求項６のように、股用吸収体の前後部を前腹部と後背部の方向にそれぞれ延長して、左右の脚穴部に沿うよう略Ｘ字形状に形成すると、脚穴部周りからの横漏れをより確実に防止できるようになる。   As in claim 6, when the front and rear parts of the crotch absorber are respectively extended in the direction of the front abdomen and the back part and formed into a substantially X shape along the left and right leg hole parts, Lateral leakage can be prevented more reliably.

請求項７のように、腰脇用吸収体の前後部を左右の脚穴部に沿うよう略Ｃ字形状に形成すると、股用吸収体を左右の脚穴部に沿うよう略Ｘ字形状に形成する（請求項６）ことと相俟って、腰脇用吸収体と股用吸収体とが脚穴部周りのほぼ全周を取り囲むようになるので、脚穴部周りからの横漏れをより確実に防止できるようになる。   When the front and rear portions of the waist-side absorbent body are formed in a substantially C shape so as to extend along the left and right leg hole portions as in claim 7, the crotch absorbent body is formed in a substantially X shape along the left and right leg hole portions. Combined with the formation (Claim 6), the waist-side absorbent body and the crotch absorbent body surround the entire circumference of the leg hole part, so that side leakage from the leg hole part is prevented. It becomes possible to prevent more reliably.

請求項８のように、股用吸収体を長方形状に形成すれば、シンプルな形状となって、コスト安になる。   If the crotch absorber is formed in a rectangular shape as in claim 8, the shape becomes simple and the cost is reduced.

請求項９のように、脚穴部を前後方向の楕円形状抜き穴に形成して、この脚穴部の周囲にほぼ沿ってレッグ用弾性糸を添設すると、脚穴が大きいので着用者の脚の出し入れがスムーズになるとともに、レッグ用弾性糸の収縮力によって、脚穴部周りからの横漏れをより確実に防止できるようになる。   If the leg hole portion is formed in an elliptical punch hole in the front-rear direction and the leg elastic yarn is attached substantially along the periphery of the leg hole portion as in claim 9, the leg hole is large, so that the wearer's The leg can be smoothly put in and out, and the side leakage from around the leg hole can be more reliably prevented by the contracting force of the leg elastic yarn.

請求項１０のように、脚穴部を前後方向のスリットに形成し、このスリットの左右にほぼ沿って、前腹部の前端と後背部の後端に亘ってレッグ用弾性糸を添設すると、脚穴部のくり抜きが不要でコスト安になるとともに、レッグ用弾性糸の収縮力によって、脚穴部周りからの横漏れをより確実に防止できるようになる。また、レッグ用弾性糸は、前腹部と後背部のボディフィット用弾性糸の下側と股用吸収体の前後端部との間の部分にも位置するようになるので、この部分のレッグ用弾性糸の収縮力によって、股用吸収体の前後端部からの漏れをより確実に防止できるようになる。さらに、レッグ用弾性糸は、前腹部の前端と後背部の後端に亘って連続的に添設されているので、レッグ用弾性糸の添設工程が容易になる。   As in claim 10, when the leg hole part is formed in a slit in the front-rear direction, and the leg elastic yarn is attached across the front end of the front abdomen and the rear end of the back part substantially along the left and right of the slit, It is not necessary to cut out the leg hole portion and the cost is reduced, and the side leakage from around the leg hole portion can be more surely prevented by the contraction force of the leg elastic yarn. In addition, the leg elastic yarn comes to be located in a portion between the lower side of the body-fit elastic yarn in the front and back parts and the front and rear ends of the crotch absorber. Leakage from the front and rear ends of the crotch absorbent can be more reliably prevented by the contraction force of the elastic yarn. Further, since the leg elastic yarn is continuously attached over the front end of the front abdomen and the rear end of the back portion, the leg elastic yarn can be attached easily.

請求項１１のように、外面側シートと肌面側シートとを接着して股部と前腹部と後背部とを構成して、腰脇用吸収体を外面側シートと肌面側シートとの間に挟着固定すると、腰脇用吸収体を製造段階で正規の位置に固定することができる。   As in claim 11, the outer surface side sheet and the skin surface side sheet are bonded to form a crotch portion, a front abdomen portion, and a back portion, and the waist-side absorbent body is composed of the outer surface side sheet and the skin surface side sheet. When sandwiched and fixed therebetween, the waist-side absorbent body can be fixed at a normal position in the manufacturing stage.

請求項１２のように、外面側シートと肌面側シートとを接着して股部と前腹部と後背部とを構成して、腰脇用吸収体を肌面側シートの上に接着固定すると、腰脇用吸収体を製造段階で正規の位置に固定できるとともに、必要に応じて後付けも可能になる。なお、交換可能に固定することも可能である。   When the outer surface side sheet and the skin surface side sheet are bonded to form the crotch part, the front abdomen part, and the back part as in claim 12, and the waist side absorbent body is bonded and fixed on the skin surface side sheet In addition, the waist-side absorbent body can be fixed at a normal position in the manufacturing stage, and can be retrofitted as necessary. It is also possible to fix it so as to be replaceable.

請求項１３のように、股用吸収体の左右位置に立ち上がりフラップを設けると、股用吸収体からの横漏れをより確実に防止できるようになる。   According to the thirteenth aspect, when the rising flaps are provided at the left and right positions of the crotch absorbent, side leakage from the crotch absorbent can be more reliably prevented.
