【発明の詳細な説明】 〔発明の属する技術分野〕 本発明は、腰部に弾性部材を有する使い捨ておむつに
関する。Description: TECHNICAL FIELD The present invention relates to a disposable diaper having an elastic member at a waist.
おむつを使用者にフィットさせ、その腰周り部分から
の漏れ（いわゆる前後漏れ）を防止するため弾性部材を
用いることは周知である。この弾性部材については、従
来、種々のものが提案されてきた。例えば、特開昭59−
59901号公報に見られるように、熱収縮性弾性部材や、
特開昭57−193501号公報に見られるように、前後腰部端
部に弾性部材を設けたものなどがある。It is well known that an elastic member is used to fit a diaper to a user and prevent leakage from the waist circumference (so-called front-back leakage). Conventionally, various types of elastic members have been proposed. For example, JP-A-59-
As seen in 59901, heat-shrinkable elastic members,
As disclosed in Japanese Patent Application Laid-Open No. 57-193501, an elastic member is provided at the front and rear waist ends.
しかしながら、従来の各種弾性部材は、おむつを着用
者の腰部に締め付けてフィットさせることのみを目的と
したものであり、着用者の動きに追従できず、着用者の
腰部とおむつの間に隙間ができ、そこから排出物が漏れ
ることが多い。However, the conventional elastic members are intended only to fit the diaper to the wearer's waist by fitting it, cannot follow the movement of the wearer, and a gap is formed between the wearer's waist and the diaper. Yes, emissions often leak from it.
特に、弾性部材をおむつ長手方向端部全体に入れるこ
とにより、小さなギャザーが生じ、このギャザーの隙間
から排泄液（尿）が滲出する。In particular, when the elastic member is inserted into the entire lengthwise end of the diaper, a small gather is generated, and excreted liquid (urine) exudes from a gap between the gathers.
さらに、腰周りに使用する弾性部材としては張力の大
きいゴム材料が主体であり、その結果、着用者に過度の
圧迫感を与えがちである。Further, as the elastic member used around the waist, a rubber material having a large tension is mainly used, and as a result, the wearer tends to give an excessive feeling of pressure.

である。The present invention for solving the above-described problems and achieving the object of the present invention is such that the body fluid absorber is wrapped between the water-permeable top sheet and the water-impermeable back sheet, and extends outward from the end of the absorber,
The front waist and the back waist have flaps at the waist corresponding positions and where there is no absorber, and elastic members are fixed along the waist direction of both flaps, and further worn on both sides of the back waist In a disposable diaper having a coupling tape that is also coupled to the front waist, a length of the elastic member of the front waist is shorter than a length of the elastic member of the rear waist, and a longitudinal end of the elastic member of the front waist. And a distance from the corresponding side edge of the flap portion is longer than a distance between the longitudinal end of the elastic member of the rear waist portion and the corresponding side edge of the flap portion. .
上記構成の本発明によると次の作用効果がもたらされ
る。According to the present invention having the above configuration, the following operation and effect can be obtained.
後腰部の弾性部材の方が前腰部の弾性部材より長
く、逆に前腰部の弾性部材が短く、かつ前腰部の弾性部
材の方が後腰部に設けた該弾性部材よりも、伸長時の張
力が小さいので、弾性部材の張力が主に背部に偏在し、
前腰部（腹部）が締めつけられることが少ないから、着
用者に快適なフィット感を与える。The elastic member at the rear waist is longer than the elastic member at the front waist, the elastic member at the front waist is shorter, and the elastic member at the front waist is more stretchable than the elastic member provided at the rear waist. Is small, the tension of the elastic member is unevenly distributed mainly on the back,
Since the front waist (abdomen) is hardly tightened, a comfortable fit is provided to the wearer.
前腰部に設けた弾性部材長が短く、その結果、弾性
部材の長手方向とフラップ部の側縁との距離が、後腰部
より長いので、使用者へのおむつの装着を容易にする。The length of the elastic member provided on the front waist is short, and as a result, the distance between the longitudinal direction of the elastic member and the side edge of the flap portion is longer than that of the rear waist, so that the diaper can be easily attached to the user.

短いと、その弾性部材の収縮に伴ない収縮している前腰
部のフラップを引き伸ばしながら前記結合テープを接着
させる必要があり、手間がかかる。That is, in order to attach the diaper, the bonding tape adhered to both side edges of the rear waist flap is adhered to the front waist flap. At this time, the elastic member length of the front waist is long, and the elastic member If the distance from the end to the side edge of the flap is short, it is necessary to adhere the connecting tape while stretching the flap of the front waist, which is contracted due to the contraction of the elastic member, and it is troublesome.
しかるに、本発明では、前腰部の弾性部材長が短く、
かつ前腰部の弾性部材端部からフラップ側縁までの距離
が長いので、前腰部のフラップ部はフラップ側縁近傍に
おいてあまり収縮おらず、引き伸ばし操作量が小さく容
易に結合テープを接着でき、おむつの装着が簡単にな
る。However, in the present invention, the elastic member length of the front waist is short,
And since the distance from the elastic member end of the front waist to the flap side edge is long, the flap portion of the front waist does not shrink so much in the vicinity of the flap side edge, the amount of stretching operation is small and the bonding tape can be easily adhered, and the diaper Installation becomes easy.
また、おむつの長手方向からいわゆる前後漏れは、後
腰部（背中）を下にして寝ている頻度が多く、背中側か

者の腰の重みによって、弾性部材が再び収縮することが
少なく、したがって、結合テープによる前部との装着性
を損わない。In addition, the so-called back-and-forth leakage from the longitudinal direction of the diaper is frequently performed with the back waist (back) down and often leaks from the back side. It is necessary to provide a sufficient contraction force (length) by making the elastic member longer than the elastic member length. Even in this case, when wearing the diaper, the back side of the diaper is deployed to lower the waist of the wearer, and then the flap By pulling both sides outward, the elastic member is less likely to contract again due to the weight of the wearer's waist, and therefore does not impair the attachment of the connecting tape to the front.
かくして、紙おむつの装着性の改良とフィット性（過
度の腹部への圧迫防止）の改良と前後漏れ防止効果の増
大とを一挙に解決できる。Thus, the improvement of the disposability of the disposable diaper, the improvement of the fit (prevention of excessive pressure on the abdomen), and the increase of the front-rear leakage prevention effect can be solved at once.

く、伸縮度を換えてもよい。Incidentally, the feature of the present invention is the length of the post-heat-shrinkable elastic band 6A.
The relationship between lB and the length lF of the front heat-shrinkable elastic band 6B is set as lB> lF, and the distance lBL from the rear heat-shrinkable band 6A to the left edge of the flap.
And the distance lF from the pre-heat-shrinkable elastic band 6B to the left edge of the flap
The relationship between L and lBL <lFL, and the relationship between the distance lBR from the rear heat-shrinkable elastic band 6A to the right edge of the flap and the distance lFR from the front heat-shrinkable elastic band 6B to the right edge of the flap is lBR <lFR. It is in. As a result, the elasticity of the rear waist is increased to prevent excessive pressure on the front waist, that is, the abdomen, and as described above, the diaper is easily worn by the user. Further, as shown in FIG. 3, a plurality of heat-shrinkable elastic bands may be provided in parallel per one flap portion.
In this case, they may be adjacent or separated, and the degree of expansion and contraction may be changed.

伸ばし操作量を小さくするようにするのが望ましい。Further, the length IB of the elastic band 6A is preferably about the same as the width 1 of the absorber 3 in order to give an appropriate contraction force, and sometimes 70 to 130% of the width 1B. About 2/3 of the width of the body 3 is preferable. Furthermore, with regard to the tension (elastic strength) of the elastic bands 6A and 6B, by reducing the elastic band 6B, the pressure on the abdomen of the wearer is reduced,
It is desirable to prevent excessive shrinkage in the region where the elastic band 6B of the flap portion exists, and to reduce the amount of stretching operation of the flap portion when the disposable diaper is attached.
さらに、弾性帯6A,6Bの幅はフラップ部の幅（紙おむ
