ープ基材特にファスニングテープの支持体については述
べられていない。The use of pressure sensitive adhesive tape as a means of securing a diaper to a wearer is well known. Various types of tape fasteners have been conventionally proposed. For example, as shown in Japanese Patent Publication No. 52-34978, a tape fastener that does not use release paper, and as shown in Japanese Utility Model Publication No. 55-75608, three tapes can be stacked and peeled off many times. There is a zipper. However, these tape fasteners are only intended to be fixed to the wearer and do not mention the tape substrate, in particular the fastening tape support.
特に本発明に述べる弾性体を有するテープファスナーを
もつおむつについては実開昭57−157209号や実開昭58−
176907号公報に見られるように非弾性部と弾性部を組み

組み合わせただけであり、フィット性、漏れ防止及びつ
かいやすさ等においてまだ十分なものは得られていな
い。Particularly, regarding the diaper having the tape fastener having the elastic body described in the present invention, No. 57-157209 and No. 58-
As seen in Japanese Patent No. 176907, a structure in which an inelastic portion and an elastic portion are combined has been proposed. However, these are simply combined, and sufficient properties such as fit, leakage prevention, and ease of use have not yet been obtained.
本発明者は鋭意研究の結果、止着テープの非弾性部と弾
性部の組み合わせ寸法、及び弾性体の物性についておむ
つ使用上重要な知見を得、目的とするフィット性、つか
いやすさ、腰部からの漏れ防止に優れるつかいすておむ
つを見出し、本発明に到達したわけである。As a result of earnest research, the present inventor has obtained important knowledge on the combined size of the non-elastic part and the elastic part of the fastening tape, and the physical properties of the elastic body in the use of the diaper, and has the desired fit, ease of use, and waist The present invention has been achieved by finding a diaper that is excellent in preventing leakage of the diaper.
即ち、本発明は、着用者に固定する手段として、止着テ
ープを有するつかいすておむつにおいて、止着テープが
以下の（１）〜（６）に示す要件を備えていることを特
徴とするつかいすておむつを提供するものである。That is, the present invention is characterized in that the fastening tape has the following requirements (1) to (6) in a diaper that has a fastening tape as means for fixing to the wearer. It is intended to provide diapers that can be pulled out.
（１） 中央部が弾性体で両端部が非弾性体であるこ
と。(1) The central part is elastic and both ends are non-elastic.
（２） 少なくとも一端部を形成する非弾性体の長さが
20〜40mmであること。(2) The length of the inelastic body forming at least one end is
20 to 40 mm.
（３） 弾性体の長さが３〜20mmであること。(3) The length of the elastic body is 3 to 20 mm.
（４） 弾性体のヒステリシス損失が20〜80％であるこ
と。(4) The hysteresis loss of the elastic body is 20 to 80%.
（５） 弾性体の200％伸長時の張力が10mm巾あたり0.2
〜0.8kgであること。(5) The tension at 200% elongation of the elastic body is 0.2 per 10 mm width.
~ 0.8 kg.
（６） 弾性体の100％伸長後の永久歪が30％以内であ
ること。(6) The permanent set after 100% elongation of the elastic body is within 30%.
本発明において重要な点は弾性体の長さと、少なくとも
一端部を形成する非弾性体、特に着用時相手側の裏面シ
ートに接着させる部分の非弾性体の長さである。The important points in the present invention are the length of the elastic body and the length of the non-elastic body forming at least one end portion, particularly the portion of the non-elastic body that is adhered to the back sheet of the other side when worn.
弾性体の長さが20mmを超えた場合、おむつを装着する
時、弾性体が伸びて相手裏面の中央部付近まで粘着テー
プが位置し、弾性部には粘着剤がついていないため弾性
部に重なる粘着剤で固定されないおむつサイド部分が広
くなりその部分からおむつがずれやすくなる。このた
め、弾性体の長さはあまり長くとることは出来ず、20mm
以内、好ましくは15mm以内に抑える必要がある。又、弾
性部が3mm以上ないとテープに伸縮性の効果が出ない。When the length of the elastic body exceeds 20 mm, when the diaper is worn, the elastic body extends and the adhesive tape is located near the center of the other side of the mating surface, and the elastic portion does not have an adhesive and overlaps the elastic portion. The side of the diaper, which is not fixed with an adhesive, becomes wider and the diaper easily slips off from that side. For this reason, the length of the elastic body cannot be too long, and is 20 mm.
Within, preferably within 15 mm. Also, if the elastic portion is 3 mm or more, the tape will not be stretchable.
又、少なくとも一端部を形成する非弾性体、特に相対す
るおむつ裏面層に接着する非弾性体の長さが20mm未満の
場合、装着時テープがつかみにくくなるため、20mm以上
必要であり、好ましくは25mm以上必要である。尚、40mm
より長くなると、装着する時、テープ端が相手裏面の中
央部付近まで位置するため着用者の腰回りが少し小さい
ともう片面のテープと重なり合う恐れがあることやコス
ト的にも問題が出てくる。Further, if the length of the non-elastic body forming at least one end portion, especially the non-elastic body adhered to the opposing diaper back surface layer is less than 20 mm, the tape becomes difficult to grip during mounting, so 20 mm or more is necessary, and preferably 25mm or more is required. 40mm
If the length becomes longer, the tape edge will be located near the center of the other side of the back of the wearer, so if the waist of the wearer is a little small, it may overlap with the tape on the other side and there will be a cost problem. .
尚、もう１つ重要な点は本発明に使用する弾性体の弾性
物性である。つまり、弾性体を100％伸長し、元にもど
した時のヒステリシス損失が20〜80％である必要があ
る。Another important point is the elastic physical properties of the elastic body used in the present invention. In other words, the elastic loss must be 20 to 80% when the elastic body is stretched 100% and returned to its original state.
ヒステリシス損失が20％未満であると装着時の引張力と
着用時の収縮力との間に差がなくなるため、弾性が弱い
と装着時テープが伸びすぎるため使いにくく、反対に弾
性が強いと、テープファスナーの収縮力が強過ぎるため
着用者の腹部を圧迫し過ぎる欠点がある。又、80％を超
えるとテープ基材は殆ど弾性を示さず、腰部を殆ど締め
つけないため、腰部へのフィット性の向上を図ることが
できない。If the hysteresis loss is less than 20%, there will be no difference between the pulling force when wearing and the contracting force when wearing, so if the elasticity is weak, the tape will stretch too much when wearing, making it difficult to use, and conversely if the elasticity is strong, Since the tape fastener has a too strong contraction force, there is a drawback that the abdomen of the wearer is pressed too much. On the other hand, if it exceeds 80%, the tape base material exhibits almost no elasticity and the waist portion is hardly tightened, so that it is impossible to improve the fit property to the waist portion.
又、弾性体の200％伸長時の張力は0.2〜0.8kg/10mmがよ
く、伸びすぎると装着時に使いづらく、伸びなさすぎる
と腰部へのフィット性が得られなくなる。尚、弾性を保
つためには、100％伸長後における永久歪は30％以内で
あることが好ましい。The tension of the elastic body at 200% elongation is preferably 0.2 to 0.8 kg / 10 mm. If it is too elongated, it will be difficult to use when it is attached, and if it is not elongated too much, it will not be able to be fitted to the waist. In order to maintain elasticity, it is preferable that the permanent set after 100% elongation is within 30%.
