Description

本発明は、特に男性の前漏れ防止性能に優れる使い捨ておむつに関するものである。 The present invention relates to a disposable diaper that is particularly excellent in men's front leakage prevention performance.

使い捨ておむつにおける漏れの形態は千差万別であるが、その中の一つの形態として、装着者が男性の場合における尿の前漏れ（使い捨ておむつの前側からの漏れ。以下、男性前漏れともいう。）がある。男性前漏れは、装着者が女性である場合には発生しないのに、装着者が男性であるとその他は同じ条件でも発生するものであり、その原因は定かではなかった。
特に従来は、陰茎の位置により排尿位置が変化することが原因であるという認識が強く、介護現場ではこの問題を解決するために、フラットタイプの補助吸収性物品を用い、その幅方向両側部を蛇腹状にして、蛇腹状部分間に陰茎を配置することにより、鼠径部から股間までの両脚の付根の溝に発生する隙間を埋めるようにしたり、特に装着者が男性のときには円錐状に丸めて陰茎に巻き付けたりする（以下、男性巻きともいう）、といった対応が取られている（例えば、特許文献１，２参照）。
また、男性巻きの装着作業の簡素化及び漏れの低減を図るために、陰茎挿入口を有する袋状吸収性物品も提案されている（例えば、特許文献３，４参照）。 There are many different types of leaks in disposable diapers, but one of them is pre-leakage of urine when the wearer is male (leak from the front side of the disposable diaper. .) The pre-male leak did not occur when the wearer was female, but it occurred even under the same conditions when the wearer was male, and the cause was not clear.
In particular, there is a strong recognition that the urination position changes due to the position of the penis, and in order to solve this problem at the nursing care site, flat type auxiliary absorbent articles are used, and both sides in the width direction are used. By making the bellows shape and placing the penis between the bellows-like parts, the gaps that occur in the root grooves of both legs from the groin to the crotch can be filled, especially when the wearer is a man, it is rounded into a conical shape A measure such as winding around the penis (hereinafter also referred to as male winding) has been taken (see, for example, Patent Documents 1 and 2).
In addition, a bag-like absorbent article having a penis insertion opening has also been proposed in order to simplify the man wearing operation and reduce leakage (see, for example, Patent Documents 3 and 4).

しかし、陰茎を包む装着形態は、陰茎が吸収性物品により拘束されるため違和感が強いといった問題点や、装着作業が煩雑になるといった問題点を有している。
そこで、本発明の主たる課題は、男性が使用する際、装着時の違和感が少ないものでありながら、前漏れ防止性能に優れる使い捨ておむつを提供することにある。 However, the mounting form for wrapping the penis has a problem that the penis is restrained by the absorbent article, so that the discomfort is strong, and a mounting operation becomes complicated.
Then, the main subject of this invention is providing the disposable diaper which is excellent in a front leak prevention performance, although there is little discomfort at the time of mounting | wearing when a man uses.

本発明者は、上記課題を解決するべく鋭意研究した結果、男性前漏れの主要因は、排尿位置よりも後方に位置する陰嚢が物品表面に密着して隙間が極端に少なくなることにより、尿の後方移動が阻害されることである、という新規な知見を得た。
以下に述べる本発明はこのような知見に基づくものである。
＜請求項１記載の発明＞

前記陰嚢配置領域の前側から後側にかけて、尿を吸収する吸収体を備えた、使い捨ておむつにおいて、
前記吸収体における少なくとも前記陰嚢配置領域の幅方向中央部に、前後方向に沿って延在する細長状の屈曲部が設けられ、この屈曲部により、前記陰嚢配置領域の前側から後側にかけて幅方向中央部が外側に膨出するように屈曲する構成とされており、
前記吸収体の両側部の上側には、陰嚢の側面に沿うように起立する陰嚢部立体ギャザーが少なくとも前記陰嚢配置領域の前側から後側にかけて延在するようにそれぞれ設けられており、
この陰嚢部立体ギャザーは、前記吸収体の側部に対して固定された固定部分と、この固定部分から突出する突出部分とを有するとともに、この突出部分のうち前記陰嚢配置領域の前端若しくはその近傍及び後端若しくはその近傍に位置する部分がそれぞれ倒伏状態で前記吸収体の側部に対して固定された非起立部とされ、これら非起立部間の部分が非固定の起立部とされ、且つこの起立部にギャザー弾性伸縮部材が前後方向に伸張した状態で固定されており、
前記屈曲部の前後方向長さが１８０〜２１０ｍｍであり、
前記陰嚢部立体ギャザーの非起立部の前後方向間隔が１５０〜１８０ｍｍであり、
前記陰嚢部立体ギャザーの固定部分の幅方向間隔が６０〜８０ｍｍである、
ことを特徴とする使い捨ておむつ。 As a result of earnest research to solve the above-mentioned problems, the present inventor has a main factor of male pre-leakage because the scrotum located behind the urination position is in close contact with the article surface and the gap is extremely reduced. A new finding was obtained that the backward movement of urine is inhibited.
The present invention described below is based on such knowledge.
<Invention of Claim 1>
It has a scrotal arrangement area where the wearer's scrotum is arranged, and an area extending to the front side and the rear side, respectively.
In a disposable diaper comprising an absorber that absorbs urine from the front side to the rear side of the scrotum arrangement region,

（作用効果）
本発明に係る使い捨ておむつは、装着状態では、陰嚢部立体ギャザーのギャザー弾性伸縮部材の収縮力の作用及び屈曲部の存在により、陰嚢配置領域の前側から後側にかけて幅方向中央部が外側に膨出するように屈曲して、表面に断面ほぼＶ字状の溝が形成され、この屈曲部上に装着者の陰嚢が位置するようになる。その結果、装着者の陰嚢と中央部の表面との間に陰嚢の前後に連通する大きな隙間が確保され、陰嚢配置領域の前側に排泄された尿のうち陰嚢配置領域の前側で吸収できない分は、この大きな隙間を流路として陰嚢配置領域の後側に流れ、陰嚢配置領域の後側の吸収体により吸収することができる。よって、陰嚢による拡散阻害を効果的に防止することができる。
特に、本発明では、陰嚢部立体ギャザーの収縮力により屈曲部の形状維持性が非常に高いこと、及び装着者の陰嚢が左右両側から陰嚢部立体ギャザーにより支えられ、所定位置に保持されることも相まって、単に吸収体に前後方向スリットを設ける周知の拡散向上技術と比べて次元の違う効果がある。
また、本発明の陰嚢部立体ギャザーは尿の遮断作用もあるため、排泄された尿が陰嚢の近傍から幅方向に拡散し難くなる結果、いわゆる横漏れも発生し難くなる。
さらに、本発明の使い捨ておむつは陰茎を包むものではないため、装着時の違和感も少ないものとなる。 (Function and effect)
The disposable diaper according to the present invention has a central portion in the width direction from the front side to the rear side of the scrotum arrangement region on the outside due to the action of the contraction force of the gather elastic elastic member of the scrotal part three-dimensional gather and the bending part in the mounted state. It is bent so as to bulge out, and a groove having a substantially V-shaped cross section is formed on the surface, and the scrotum of the wearer is positioned on the bent portion. As a result, a large gap communicating between the front and back of the scrotum is ensured between the scrotum of the wearer and the center surface, and the urine excreted on the front side of the scrotum placement area is on the front side of the scrotum placement area. The portion that cannot be absorbed flows to the back side of the scrotum placement region using this large gap as a flow path, and can be absorbed by the absorber on the back side of the scrotum placement region. Therefore, diffusion inhibition by the scrotum can be effectively prevented.

また、陰嚢部立体ギャザーの起立部の前後方向長さ（遮断範囲）の短さを補うために、前述のとおり陰嚢部立体ギャザーとは別に側部立体ギャザーを設けるのも好ましいが、一般的な使い捨ておむつと比べて資材量・コストが嵩むとともに、製造工程が増加するという問題がある。そこで、上述のように、側部立体ギャザーの固定部の幅を変化させることにより、側部立体ギャザーの一部を陰嚢部立体ギャザーとするのも好ましい形態である。この形態は、固定部の変更だけであるため、資材量・コストが殆ど嵩むことがなく、製造工程も殆ど増加せずに済み、もちろん製造も容易である。 (Function and effect)
The disposable diaper according to the present invention has a central portion in the width direction from the front side to the rear side of the scrotum arrangement region on the outside due to the action of the contraction force of the gather elastic elastic member of the scrotal part three-dimensional gather and the bending part in the mounted state. It is bent so as to bulge out, and a groove having a substantially V-shaped cross section is formed on the surface, and the scrotum of the wearer is positioned on the bent portion. As a result, a large gap communicating between the front and back of the scrotum is ensured between the scrotum of the wearer and the center surface, and the urine excreted on the front side of the scrotum placement area is on the front side of the scrotum placement area. The portion that cannot be absorbed flows to the back side of the scrotum placement region using this large gap as a flow path, and can be absorbed by the absorber on the back side of the scrotum placement region. Therefore, diffusion inhibition by the scrotum can be effectively prevented.
In particular, in the present invention, the shape maintaining property of the bent portion is very high due to the contraction force of the scrotal part gather, and the wearer's scrotum is supported by the scrotum part gather from both sides and held in place. Coupled with this, there is an effect that the dimension is different from that of a known diffusion improving technique in which the front and rear slits are simply provided in the absorber.
Moreover, since the scrotal part three-dimensional gather of this invention also has the blocking | blocking effect | action of urine, as a result that it becomes difficult for the excreted urine to spread | diffuse in the width direction from the vicinity of the scrotum, what is called a side leak becomes difficult to generate | occur | produce.
Furthermore, since the disposable diaper of the present invention does not wrap the penis, there is little discomfort when worn.
Further, in order to compensate for the short length of the up-and-down direction of the standing part of the scrotal part gathers (blocking range), it is preferable to provide a side part gathers separately from the scrotum part gathers as described above. Compared with typical disposable diapers, there are problems that the amount of material and cost increase and the manufacturing process increases. Therefore, as described above, it is also a preferable embodiment that a part of the side solid gather is changed to the scrotal solid gather by changing the width of the fixing portion of the side solid gather. Since this form is only a change of the fixing portion, the amount of material and cost are hardly increased, the manufacturing process is hardly increased, and, of course, manufacture is easy.

以上のとおり本発明によれば、男性が使用する際、装着時の違和感が少ないものでありながら、前漏れ防止性能に優れるようになる、等の利点がもたらされる。 As described above, according to the present invention, there is an advantage that, when a man uses it, the discomfort at the time of wearing is small, but the front leakage prevention performance is improved.

The bent portion 50 is configured to bend so that the central portion in the width direction bulges outward from the front side to the rear side of the scrotum arrangement region C1.
The bent part 50 is a part configured to promote bending with the part as a boundary. Specifically, the bent part 50 has a slit (penetrating from the front surface to the back surface of the absorber 23 as in the illustrated example). (Parts) and recesses (including those formed by pressure processing such as embossing, as well as elongated thin portions formed without pressure), or folds (folded lines) are continuous or dotted It can be provided by forming (intermittently).
The size of the bent portion 50 can be determined as appropriate, but considering the size of the scrotum of a standard adult male using this type of disposable diaper, the length in the front-rear direction (the total length in the case of a dotted line) 50L is 180 to 210 mm. It is preferable to set the degree. Further, the width 50W of the bent portion 50 can be determined as appropriate, but it is preferably about 20 to 40 mm in a normal case because the shape maintaining property of the gap described later is better if it is not too wide.
The position of the bent portion 50 can be determined as appropriate. However, when the bent portion 50 is positioned between the non-erected portions 45 of the scrotum three-dimensional gather 40 in the front-rear direction, the contraction force of the scrotal three-dimensional gather 40 with respect to the bent portion 50 Is preferable because it works effectively.

（装着状態）
装着状態では、陰嚢部立体ギャザー４０のギャザー弾性伸縮部材の収縮力の作用及び屈曲部５０の存在により、図４に二点差線で示すように、陰嚢配置領域Ｃ１の前側から後側にかけて幅方向中央部が外側に膨出するように屈曲して、図５及び図６に示すように、表面に断面ほぼＶ字状の溝が形成され、この屈曲部５０上に装着者の陰嚢ＳＣが位置するようになる。その結果、装着者の陰嚢ＳＣと中央部の表面との間に陰嚢ＳＣの前後に連通する大きな隙間５０Ｄが確保され、陰嚢配置領域Ｃ１の前側に排泄された尿のうち陰嚢配置領域Ｃ１の前側で吸収できない分は、この大きな隙間５０Ｄを流路として陰嚢配置領域Ｃ１の後側に流れ、陰嚢配置領域Ｃ１の後側の吸収体２３により吸収することができる。よって、陰嚢ＳＣによる拡散阻害を効果的に防止することができる。
そして、陰嚢部立体ギャザー４０の収縮力により屈曲部５０の形状維持性が非常に高いこと、及び装着者の陰嚢ＳＣが左右両側から陰嚢部立体ギャザー４０により支えられ、所定位置に保持されることも相まって、単に吸収体２３に前後方向スリットを設ける周知の拡散向上技術と比べて次元の違う効果が奏せられる。
また、陰嚢部立体ギャザー４０は尿の遮断作用もあるため、排泄された尿が陰嚢ＳＣの近傍から幅方向に拡散し難くなる結果、いわゆる横漏れも発生し難くなる。ただし、陰嚢部立体ギャザー４０の起立部の前後方向長さ（遮断範囲）は短いため、当該使い捨ておむつ内でより確実に横漏れを防止するためには、幅方向外側に上述の側部立体ギャザー３０を組み合わせるのが好ましい。 (Worn state)
In the mounted state, due to the action of the contraction force of the gather elastic elastic member of the scrotal part three-dimensional gather 40 and the presence of the bent part 50, from the front side to the rear side of the scrotum arrangement area C1, as shown by the two-dot chain line in FIG. The central portion in the width direction is bent so as to bulge outward, and a groove having a substantially V-shaped cross section is formed on the surface as shown in FIGS. 5 and 6, and the scrotum of the wearer is formed on the bent portion 50. SC will be located. As a result, a large gap 50D communicating between the scrotum SC and the front and back of the scrotum SC is ensured between the scrotum SC of the wearer and the surface of the central portion, and the scrotum is arranged in the urine excreted in the front side of the scrotum arrangement area C1. The amount that cannot be absorbed on the front side of the region C1 can flow to the rear side of the scrotum placement region C1 using this large gap 50D as a flow path, and can be absorbed by the absorber 23 on the rear side of the scrotum placement region C1. Therefore, it is possible to effectively prevent diffusion inhibition by the scrotum SC.
The shape maintaining property of the bent portion 50 is very high due to the contraction force of the scrotum three-dimensional gather 40, and the wearer's scrotum SC is supported by the scrotum three-dimensional gather 40 from both the left and right sides and held in place. In combination with this, an effect of a different dimension can be achieved as compared with a known diffusion enhancing technique in which the front and rear direction slits are simply provided in the absorber 23.
In addition, since the scrotal part three-dimensional gather 40 also has a urinary blocking function, the excreted urine is less likely to diffuse in the width direction from the vicinity of the scrotum SC, and so-called side leakage is less likely to occur. However, since the length in the front-rear direction (blocking range) of the upright part of the scrotal part three-dimensional gather 40 is short, in order to prevent side leakage more reliably in the disposable diaper, the above-mentioned side part three-dimensional part is disposed outward in the width direction. It is preferable to combine the gathers 30.

＜第２の形態＞
上記第１の形態における側部立体ギャザー３０を省略し、陰嚢部立体ギャザー４０のみとすることも可能である。特に、図示形態のようなパッドタイプ使い捨ておむつは、テープタイプ使い捨ておむつ等のアウター使い捨ておむつの内面に敷いて使用することもあるため、そのような使用形態では、陰嚢部立体ギャザー４０のみとして仮に当該パッドタイプ使い捨ておむつからの漏れが発生しても、アウター使い捨ておむつにより吸収することができる。 <Second form>
It is also possible to omit the side three-dimensional gather 30 in the first embodiment and use only the scrotal three-dimensional gather 40. In particular, the pad-type disposable diaper as shown in the figure may be used by laying it on the inner surface of an outer disposable diaper such as a tape-type disposable diaper. Even if leakage occurs from the pad-type disposable diaper, it can be absorbed by the outer disposable diaper.

＜第３の形態＞
陰嚢部立体ギャザー４０の起立部の前後方向長さ（遮断範囲）の短さを補うために、前述のとおり陰嚢部立体ギャザー４０とは別に側部立体ギャザー３０を設けるのも好ましいが、一般的な使い捨ておむつと比べて資材量・コストが嵩むとともに、製造工程が増加するという問題がある。そこで、図７〜図９に示すように、側部立体ギャザー３０の固定部の幅を変化させることにより、側部立体ギャザー３０の一部を陰嚢部立体ギャザー４０とした形態も提案する。この形態は、固定部の変更だけであるため、資材量・コストが殆ど嵩むことがなく、製造工程も殆ど増加せずに済み、もちろん製造も容易である。
より詳細には、第１の形態における陰嚢部立体ギャザー４０を省略するとともに、側部立体ギャザー３０の固定部３４を、陰嚢配置領域Ｃ１の前側から後側にわたる前後方向中間部分３８Ｙにおいて、その前後よりも幅方向中央側に張り出させて、吸収体２３の側部に対して固定するようにしたものである。これにより、側部立体ギャザー３０における固定部３４の張り出し部分３８が、第１の形態における陰嚢部立体ギャザー４０と同等の機能を発揮するようになる。
固定部３４の貼り出し部分３８の幅３８Ｗ、及びそれ以外の部分の幅３４Ｗは、第１の形態における陰嚢部立体ギャザー４０の固定部分の幅方向間隔、及び側部立体ギャザー３０の固定部分の幅方向間隔に合わせて定めることができる。
その他は第１の形態と同様であるため敢えて説明を省略する。 <Third embodiment>
In order to compensate for the short length of the up-and-down direction of the standing part of the scrotal part gather 40 (blocking range), it is preferable to provide the side part gathers 30 separately from the scrotum part gathers 40 as described above. Compared with a general disposable diaper, there are problems that the amount of material and cost increase and the manufacturing process increases. Accordingly, as shown in FIGS. 7 to 9, a configuration is also proposed in which a part of the side three-dimensional gather 30 is changed to the scrotal three-dimensional gather 40 by changing the width of the fixing portion of the side three-dimensional gather 30. Since this form is only a change of the fixing portion, the amount of material and cost are hardly increased, the manufacturing process is hardly increased, and, of course, manufacture is easy.
More specifically, the scrotal part three-dimensional gather 40 in the first form is omitted, and the fixing part 34 of the side three-dimensional gather 30 is arranged in the front-rear direction intermediate portion 38Y extending from the front side to the rear side of the scrotum arrangement region C1. It protrudes to the center side in the width direction from the front and back, and is fixed to the side portion of the absorber 23. Thereby, the overhang | projection part 38 of the fixing | fixed part 34 in the side part three-dimensional gather 30 comes to exhibit a function equivalent to the scrotal part three-dimensional gather 40 in a 1st form.
The width 38W of the sticking part 38 of the fixing part 34 and the width 34W of the other part are the width-direction interval of the fixing part of the scrotal three-dimensional gather 40 and the fixing part of the side three-dimensional gather 30 in the first embodiment. It can be determined according to the interval in the width direction.
Since others are the same as those of the first embodiment, the description will be omitted.

本発明は、パッドタイプ、パンツタイプ若しくはテープタイプ等、使い捨ておむつ全般に利用できるものである。 INDUSTRIAL APPLICABILITY The present invention can be used for all disposable diapers such as a pad type, a pants type, or a tape type.
