本発明は、熱収縮性などの弾性部材を有する使い捨てお
むつに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disposable diaper having an elastic member such as heat-shrinkable material.
おむつを使用者にフィツトさせ、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を設けたものなどがある。It is well known to use elastic members to fit a diaper to a user and prevent leakage from the waist area (so-called front and rear leakage). Various types of elastic members have been proposed in the past. For example, JP-A-59-
There are heat-shrinkable elastic members as seen in Japanese Patent Laid-Open No. 59901, and elastic parts provided at the front and rear waist ends as seen in Japanese Patent Application Laid-open No. 57-193501.
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ツトさせることのみを目的とし
たものであり、着用時に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、そこから排泄物
が洩れることが多い。However, the various conventional elastic members are only intended to tighten and fit the diaper around the wearer's waist, and cannot follow the wearer's movements when worn, and there is a gap between the wearer's waist and the diaper. A gap is formed through which excrement often leaks.
また、弾性部材をおむつの長手方向端部全体に入れるこ
とにより、小さなギヤザーが生じ、このギヤザーの隙間
から排泄物が滲出する。In addition, by inserting the elastic member into the entire longitudinal end of the diaper, small gathers are generated, and excrement oozes out from the gaps between the gathers.
さらに、腰周りに使用する弾性体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。Furthermore, the elastic material used around the waist is mainly made of rubber material with high tension, which tends to give the wearer an excessive feeling of pressure.
そこで本発明の主たる目的は、前後漏れを効果的に防止
するとともに、着用者に快適なフィツト感を与えること
のできる使い捨ておむつを提供することにある。SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a disposable diaper that can effectively prevent front-to-back leakage and provide a comfortable fit for the wearer.
上記問題点を解消し本発明の目的を達成するための手段
は、
透水性トップシートと不透水性バックシートとの間に体
液吸収体が包まれ、吸収体の端より外方に伸び、腰部対
応位置にあって吸収体が存在しないフラップ部を有し、
かつ、該フラップ部の腰周り方向に沿って弾性部材が固
定された使い捨ておむつにおいて、該弾性部材の長さが
後腰部より前腰部の方が短いことを特徴とするものであ
る。Means for solving the above problems and achieving the object of the present invention is that a body fluid absorbent is wrapped between a water-permeable top sheet and a water-impermeable back sheet, and extends outward from the edge of the absorber, and extends outward from the end of the absorbent body to the waist. It has a flap part in a corresponding position and no absorbent body,
Further, in the disposable diaper in which an elastic member is fixed along the direction around the waist of the flap portion, the length of the elastic member is shorter in the front waist region than in the back waist region.
本発明では、前腰部に設ける弾性部材の長さを後腰部に
設ける該弾性部材の長さより短かくしたことが主たる特
徴であり、このため、次の利点がある。The main feature of the present invention is that the length of the elastic member provided in the front waist region is shorter than the length of the elastic member provided in the rear waist region, and this provides the following advantages.
■ 後腰部の弾性部材の方が長いから、弾性部材の張力
が主に背部に偏在し、前部（すなわち腰部）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ツト感を
与える。(2) Since the elastic member in the back waist region is longer, the tension of the elastic member is mainly unevenly distributed in the back region, and the front region (ie, the waist region) is less likely to be tightened, giving the wearer a comfortable fit.
■ 前腰部に設けた弾性部材長が短いことは、使用者へ
のおむつの装着を容易にする。すなわち、おむつを装着

き、前腰部の弾性部材長が長いと、その弾性部材の収縮
に伴ない収縮している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。- The short length of the elastic member provided at the front waist makes it easier for the user to put on the diaper. In other words, in order to put on the diaper, the binding tape that is attached to the side edge of the flap in the rear waist area is glued to the flap in the front waist area, but at this time, if the elastic member in the front waist area is long, the elastic member It is necessary to adhere the binding tape while stretching the flap, which is shrinking as the flap shrinks, which is time-consuming.
一方、本発明では、前腰部の弾性部材長が短いので、前
腰部のフラップ部はあまり収縮していないから引き伸ば
さずに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。On the other hand, in the present invention, since the length of the elastic member in the front waist part is short, the flap part in the front waist part is not so contracted that the binding tape can be easily attached without stretching, making it easy to put on the diaper.

、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 front-to-back leakage from the longitudinal direction of the diaper is often caused by leakage from the back side because most people sleep with their rear lumbar region (back) down. It is necessary to make the diaper longer than the waist to give sufficient contraction force (length). Even with this, when putting on the diaper, the back side of the diaper is unfolded to lower the wearer's waist, and then both sides of the flaps are If the elastic member is pulled laterally and outwardly, the elastic member is less likely to contract again due to the weight of the wearer's waist, and therefore the ease of attachment to the front part by the binding tape is not impaired.
以下本発明を図面に示す具体例を参照しつつさらに詳説
する。The present invention will be explained in more detail below with reference to specific examples shown in the drawings.

ップシート１とポリエチレン等の非透水性材料からなる
バックシート２との間に、周囲を残して綿状バルブを主
体とする吸収体３を包んだ基本構成をなしている。Figures 1 and 2 show a first embodiment of a disposable diaper, which consists of a top sheet 1 made of a water-permeable material such as nonwoven fabric, and a back sheet 2 made of a non-water-permeable material such as polyethylene. The basic structure is such that an absorbent body 3, which is mainly composed of a cotton-like bulb, is wrapped between the absorbent body 3 and the surrounding area.

Preferably, a heat-shrinkable elastic band 6A is provided along the width direction of the diaper (horizontal direction in FIG. 1) before and after the edge (flap portion) 5 where the absorber 3 is not present at the longitudinal end of the diaper.
6B is provided.

The heat-shrinkable elastic bands 6A and 6B, which expand and contract in the direction around the waist, are fixed to at least one of the sheets 1.2 in an unshrinked state, and are later shrunk by receiving heat, thereby shrinking the flap portion.

The basic layer configuration of this bonding tape 7 is itself known to those skilled in the art as a two-layer tape. The binding tape 7 is adhered to the front surface of the disposable diaper during use, thereby binding the front and rear waist flaps.

The purpose is to set the length of B to 6A>6B. This increases the elasticity of the rear lumbar region, prevents excessive pressure on the front lumbar region, that is, the abdomen, and makes it easier for the user to wear the diaper as described above. Further, as shown in FIG. 3, a plurality of heat-shrinkable elastic bands may be provided in parallel per one flap. In this case, they may be adjacent or separated, and the degree of expansion and contraction may be changed.

のが望ましい。In addition, the length l of the elastic band 6A is preferably about the same as the width 10 of the absorber 3 in order to provide an appropriate contractile force, and may be 70 to 130% of the width in some cases.Furthermore, the length l of the elastic band 6B is The width of the body 3 is preferably about 273 mm. Furthermore, it is desirable that the tension (elastic strength) of the elastic bands 6A and 6B is made weaker in the elastic band 6B.
着用者の腹部への圧迫を考慮したものである。さらに、
弾性帯６Ａ、６Ｂの幅はフラップ部の幅（紙おむつの長

しい。This takes into consideration the pressure on the wearer's abdomen. moreover,
The width of the elastic bands 6A, 6B is preferably 20 to 150% of the width of the flap portion (width in the longitudinal direction of the paper diaper).
