本発明は熱収縮性弾性帯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 a heat-shrinkable elastic band.
近年、この種のおむつにおいて、その腰周り部からの漏
れ（いわゆる前後漏れ）を防止することが重要であるこ
とが認識され、その解決手段がいくつか提案されている
。この代表例の１つは、特開昭６０−１７１０１号公報
に記載のように、おむつの腰周り全集に亘って、弾性収
縮性腰バンドを設けたものである。また、他には、特開
昭６１−８３３６８号公報に記載されているもので、お
むつの腰周り部分に通常のゴムバンドに代えて、熱収縮
性弾性伸縮帯を設けたものなどが知られている。In recent years, it has been recognized that it is important to prevent leakage from the waist area (so-called front and rear leakage) in this type of diaper, and several solutions have been proposed. One of the typical examples is a diaper in which an elastic waist band is provided around the entire waist area, as described in Japanese Patent Application Laid-open No. 17101/1983. In addition, there is also a diaper described in Japanese Patent Application Laid-open No. 61-83368, in which a heat-shrinkable elastic band is provided around the waist of the diaper in place of the usual rubber band. ing.
しかしながら、上記従来のおむつには以下の欠点がある
。すなわち、一般に使い捨ておむつを幼児に装着するに
は、おむつ上に幼児を横たえ、上記結合テープを結合さ
せるため、おむつの弾性帯が幼児の下敷となり、結合テ
ープの引張りに追従しに＜＜、本来の弾性機能を発揮で
きない。However, the conventional diapers described above have the following drawbacks. In other words, generally when putting a disposable diaper on an infant, the infant is laid down on the diaper and the binding tape is bonded to the infant. cannot demonstrate its elastic function.
また、腰周りの全周に弾性部材を設けているので、微小
な起伏をもったギヤザ一部が生じ、この起伏から前後漏
れを生じやすい。さらに、着用者の動きに応じて生じる
弾性帯の伸縮性は、腰部の側部に集中し、したがってそ
の側部に伸縮部材を設けるだけでも充分なフィツト性が
確保されることから考えると、他の部分に装着されてい
る弾性部材は無駄である。Furthermore, since the elastic member is provided all around the waist, a part of the wearer has small undulations, and these undulations tend to cause leakage from the front to the rear. Furthermore, considering that the elasticity of the elastic band that occurs in response to the wearer's movements is concentrated on the sides of the waist, and that sufficient fit can be ensured just by providing an elastic member on that side, it is difficult to The elastic member attached to the part is useless.
そこで本発明の主たる目的は、材料費の無駄がなく、着
用者へのフィツト性が向上した使い捨ておむつを提供す
ることにある。Therefore, the main object of the present invention is to provide a disposable diaper that does not waste material costs and has improved fit to the wearer.
上記問題点を解決し、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、吸収帯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、おむつの装着時に前後腰部対応フラップ部を結合
する結合テープをフラップ部両側部に備えた使い捨てお
むつにおいて、前記フラップ部の腰周り方向に沿って、
前記結合テープの取付部付近であり、かつおむつ巾中央
部を除く領域に、熱収縮性弾性帯を固着したことを特徴
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 absorber is wrapped between a water-permeable top sheet and a water-impermeable back sheet, and extends outward from the edge of the absorption band.
In a disposable diaper, the disposable diaper has a flap portion located at a position corresponding to the waist region and without an absorbent body, and is provided with binding tapes on both sides of the flap portion to connect the flap portions corresponding to the front and rear waist regions when the diaper is worn, in the direction around the waist of the flap portion. along,
The present invention is characterized in that a heat-shrinkable elastic band is fixed to a region near the attaching portion of the binding tape and excluding the center portion of the diaper width.
本発明では、熱収縮性弾性帯を前後腰部対応フラップ部
を結合するテープの取付部（着用者の横倒部に対応する
部位）のみに設けることが特徴である。このため次のよ
うな利点がある。The present invention is characterized in that the heat-shrinkable elastic band is provided only at the attachment portion of the tape that connects the front and rear waist flap portions (the portion corresponding to the sideways position of the wearer). This has the following advantages.
■ おむつを使用者に着用する際、おむつ上に使用者を
横たえた後、結合テープを結合する際、弾性帯が使用者
により圧迫されない側部にのみ存在するため、該テープ
の伸張に充分追従することができ、適度なフィツト感を
着用者に与え、漏れを防止できる。■ When putting the diaper on the user, after the user lies down on the diaper and the binding tape is joined, the elastic band exists only on the sides that are not pressed by the user, so it fully follows the expansion of the tape. This provides a suitable fit for the wearer and prevents leakage.
■ 使用する熱収縮性弾性体長が短くてすみ、資材の無
駄がなくなる。■ The length of the heat-shrinkable elastic body used can be short, eliminating waste of materials.
■ ギヤザ一部が生じない為、フィツト性が高まり、前
後漏れを防止できる。■ Since there are no gears, the fit is improved and leakage from front to back can be prevented.
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。Hereinafter, the present invention will be explained in more detail with reference to specific examples shown in the drawings.

体とする吸収体３を包んだ基本構成をなしている。Figures 1 to 3 show a first embodiment of a disposable diaper, which consists of a top sheet 1 made of a water-permeable material such as non-woven fabric and a back sheet 2 made of a non-water-permeable material such as polyethylene. It has a basic structure in which an absorbent body 3 mainly consisting of a cotton-like bulb is wrapped in between, leaving the periphery.

る。Elastic stretchable members 4 made of rubber or the like are provided on both sides of the diaper along the longitudinal direction (vertical direction in FIG. 1). Also,
In the front part of the edge (flap part) 5 where the absorbent body 3 is not present at both ends in the longitudinal direction of the diaper, there is a flap in the width direction of the diaper (the first
A binding tape 7 for connecting the front and rear waist portions is provided along the left-right direction in the figure. As shown in FIG. 2, this bonding tape 7 includes a release tape 8 bonded onto the top sheet 1 by, for example, hot melt, and the back sheet 2.
Connecting piece 9 adhesively formed on the lower surface of the
It basically consists of an inelastic piece 10 which is adhesively formed on the upper surface of the tip of the connecting piece 9 by realmelt or the like.
結合テープ７は、未使用時、非弾性片１０が剥離テープ
８上に粘着剤層等を介して重ね合わせられ、使用に際し

紙おむつの前面に接着する。When the binding tape 7 is not in use, the inelastic piece 10 is superimposed on the release tape 8 via an adhesive layer or the like, and when used, the inelastic piece 10 is peeled off from the release tape 8.
Glue it to the front of the disposable diaper.

介装されている（第２図、第３図参照）。そして熱収縮
性弾性部材６は伸張状態で両シート１．２の少なくとも
一方に固着されているので、加熱によって収縮する。Further, in the flap portion 5, a heat-shrinkable member 6 disclosed in Japanese Patent Application Laid-open No. 155783/1983 is interposed between the top sheet 1 and the back sheet 2 near the attachment portion of the binding tape. (See Figures 2 and 3). Since the heat-shrinkable elastic member 6 is fixed to at least one of the sheets 1.2 in a stretched state, it shrinks when heated.
また、該熱収縮性弾性体の取付け位置は、第４図に示す
ように、結合テープ７の取付位置より、おむつの長手方
向端部側に設けてもよい。これにより内側に反り返る形
になり、背からのもれ防止と、さらにフィツト性が向上
する。Moreover, the attachment position of the heat-shrinkable elastic body may be provided closer to the longitudinal end of the diaper than the attachment position of the binding tape 7, as shown in FIG. This allows it to curve inward, preventing leakage from the back and improving the fit.

０ｇ、特に１００〜２００ｇが好適である。Heat-shrinkable elastic band length provided at the rear of the disposable diaper! is shorter than the width of the absorbent body 3, and it is better for the front part to be shorter than the rear part. The thickness (1) of the heat-shrinkable elastic band 6 is preferably 1 to ioms, particularly 2 to 10+n, from the viewpoint of cushioning properties for the wearer. The width W is preferably 20 to 100% of the distance W0 from the edge of the absorbent body 3 to the edge of the flap portion, but it may also be made to extend to about 150%, that is, to the surface of the absorbent body 3. Further, the elastic band 6 preferably has a stretching ratio of 110 to 250%, particularly 150 to 200%, and an elastic strength of 50 to 40%.
0g, especially 100-200g is suitable.
さらに、該弾性体６は外観の向上のため、予め青や緑等
