本発明は、弾性伸縮部材を有する紙おむつや生理用ナプ
キンなどの吸収性物品に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to absorbent articles such as paper diapers and sanitary napkins that have an elastic stretchable member.
近年、この種のおむつにおいて、その腰回り部分からの
漏れを防止することが重要であることが着目され、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６１−８３３６８号公報記載のように、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、収縮に際しては、熱風を用いるもの
である。In recent years, attention has been focused on the importance of preventing leakage from the waist area of this type of diaper, and several solutions have been proposed. One typical example of this is as described in JP-A No. 61-83368, in which a heat-shrinkable elastic band is provided around the waist of the diaper in place of a normal rubber band, and hot air is used to shrink the diaper. It is used.
他の１つは、実開昭６０−３０６号公報のように、腰周
り部分を疎水性接着剤にてトップシートとバックシート
とを接着するものである。Another method, as disclosed in Japanese Utility Model Application Publication No. 60-306, is to adhere a top sheet and a back sheet around the waist using a hydrophobic adhesive.
さらに、特開昭６０−１７１０１号公報のように、弾性
伸縮部材をその全体において紙おむつのシートに接着剤
を介して固着するものも知られている。Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 17101/1984, there is also known a device in which an elastic stretchable member is fixed in its entirety to a sheet of a paper diaper via an adhesive.
しかし、前記の第１構造のものでは、透水性のトップシ
ートを伝って尿がおむつの長手方向端までにじみ出るこ
とが多く、また弾性帯の伸縮に伴う小さな波状起伏の谷
から漏れることがある。However, with the first structure, urine often oozes out to the longitudinal ends of the diaper through the water-permeable top sheet, and sometimes leaks from the valleys of small undulations accompanying the expansion and contraction of the elastic band.
第２構造のものでは、弾性帯が存在しないので、着用者
の動きに伴って、着用者の肌とおむつの表面との間に隙
間ができ、尿が漏れてしまう。In the second structure, since there is no elastic band, as the wearer moves, a gap is created between the wearer's skin and the surface of the diaper, causing urine to leak.
このように、従来の個々の技術では、紙おむつの腰部か
らの漏れ、いわゆる前後漏れを防止することができなか
った。As described above, with each conventional technique, it has not been possible to prevent leakage from the waist of a disposable diaper, so-called front-to-back leakage.
一方、特開昭６０−１７１０１号公報などにおける腰周
りや脚周りに弾性伸縮部材を設ける場合、その全長にわ
たる接着剤によりトップシートおよび末たはバックシー
トに固着している。On the other hand, when an elastic elastic member is provided around the waist or around the legs, such as in Japanese Patent Application Laid-Open No. 60-17101, the elastic member is fixed to the top sheet and the back sheet using an adhesive over the entire length.
しかし、弾性伸縮部材を全長にわたってシートに固着す
ると、弾性伸縮部材がシートと共に伸縮するので、収縮
したとき特にトップシートに小さな無数の鋭角のシワが
でき、このシワが着用者の肌に触れるため、肌ざわりを
悪化させる原因となっていた。また、ホントメルト接着
剤を弾性伸縮部材の全長に塗布すると、ホットメルト接
着剤の使用量が多くなりコスト的に不利になるし、さら
にその老化に伴う変色が全長にわたって現われ外観を損
う。However, when the elastic elastic member is fixed to the sheet over its entire length, the elastic elastic member expands and contracts along with the sheet, and when it contracts, it creates numerous small, sharp wrinkles, especially on the top sheet, and these wrinkles come into contact with the wearer's skin. This was a cause of worsening the texture of the skin. Furthermore, if a true melt adhesive is applied over the entire length of the elastic elastic member, the amount of hot melt adhesive used will increase, resulting in a cost disadvantage, and furthermore, discoloration due to aging will appear over the entire length, impairing the appearance.
そこで、本発明の主たる目的は、肌に対する感触性に優
れ、しかも体液の漏れを防止し得る吸収性物品を提供す
ることにある。Therefore, the main object of the present invention is to provide an absorbent article that has excellent tactility on the skin and can prevent leakage of body fluids.

の弾性伸縮部材をその長手方向両端部のみにおいて固着
したことを特徴とするものである。In order to solve the above problems, the present invention has a body fluid absorbent interposed between a liquid-permeable top sheet and a liquid-impermeable backsheet, and there is no absorbent body extending outward from the edge of the absorbent body. In an absorbent article having a flap part; at least one elastic elastic member is fixed to at least one of the top sheet and the back sheet of the flap part only at both longitudinal ends thereof. It is characterized by this.

The middle part is free, and the top sheet only has large folds due to contraction of the elastic stretchable member, but no small wrinkles, which improves the feel.

、接着剤の老化による外観の低下部分が少くなる。Furthermore, the amount of adhesive used for fixing the elastic elastic member to the sheet can be reduced, thereby reducing costs, and the appearance deteriorates less due to aging of the adhesive.
以下本発明を図面に示す吸収性物品として紙おむつであ
る実施例によってさらに詳述する。The present invention will be explained in further detail below using examples in which a paper diaper is used as an absorbent article shown in the drawings.

シート１．２のフラップ部が構成されている。Figures 1 and 2 show a first embodiment, and this disposable diaper consists of a liquid-permeable top sheet 1 made of a non-woven fabric of about 20 to 50 g/m'' and a liquid-impermeable backing made of a polyethylene film or the like. A body fluid absorber 3 made of cotton-like pulp or the like is interposed between the sheet 2 and the absorber 3 in the longitudinal direction (vertical direction in Figure 1) and width direction (horizontal direction in Figure 1) than the sheet 1.2. ) and are both short (), thereby forming a flap portion of the sheet 1.2 in which no absorbent body 3 is present at both ends in the longitudinal direction and both ends in the width direction.

る。Further, elastic elastic members 4.4 for the leg circumference are provided adjacent to both sides in the width direction of the absorbent body 3, and on the other hand, a long back side and a short ventral side for the waist area are provided adjacent to both longitudinal ends of the absorbent body 3. An elastic elastic member 5.6 is provided. 7 is a binding tape.

り被覆されている。On the other hand, as can be seen in Fig. 2, between the top sheet 1 and the back sheet 2, there is a true melt thin film 8 of about 10 to 100 g/m'' to fix them together and prevent body fluids from seeping out. This thin film 8 extends along the entire length in the longitudinal direction and in the width direction of the disposable diaper from the position of the elastic elastic members 4, 4 to the outer side of the diaper, and in the central part, the thin film 8 extends to the outer side of the diaper through the top sheet 1. A window 8a is formed for absorbing body fluids into the absorbent body 3, and therefore, the upper surface of the peripheral edge of the top sheet 1 of the absorbent body 3 is covered with a hot melt thin film.

となっている。Furthermore, the true melt thin film 8 is not provided at the location where the elastic stretchable member 5 is provided. Then, the elastic stretchable member 5 is fixed to the backsheet 2 only at both ends in the width direction of the disposable diaper, for example, with a true melt adhesive 9,
The middle part is not constrained by the hot melt thin film 8 and is completely free.

となっている。The other elastic elastic member 6 is entirely fixed to the top sheet 1 by a hot melt thin film 8, and is also attached to the back sheet 2 with a true melt adhesive (
(not shown) and is therefore fully restrained.

れている。Regarding the elastic stretchable member 4 around the legs, a small window in which the hot melt thin film 8 does not exist is formed only in the middle part in the longitudinal direction, and both longitudinal ends of the elastic stretchable member 4 are formed with a back on the side of the back sheet 2. It is fixed to the sheet 2 with a hot melt adhesive 10. Also, of course, the surfaces of the top sheet 1 at both ends of the elastic elastic member 4 are fixed to the top sheet 1 by the presence of the hot melt thin film 8.

Ｂを設けた例である。FIG. 3 shows an example in which the hot melt thin film 8 is also coated on the elastic stretchable member 5, but only that part is not melted using a cooling roll or the like, and therefore is not bonded. Similarly, FIGS. 4 and 5 show two elastic elastic members 5A and 5.
This is an example in which B is provided.
