【発明の詳細な説明】 〔産業上の利用分野〕 本発明はつかいすておむつに関し、詳しくは、装着し

示されている。As a means for fixing the diaper to the wearer, a pressure-sensitive adhesive tape having a surface coated with an adhesive is generally used. Various types of pressure-sensitive adhesive tapes have been conventionally proposed. For example, as a mainstream, for the purpose of peeling off a tape once pressed and re-pressing again (for example, when confirming the presence or absence of urination), the pressure-sensitive adhesive tape is detachably attached to the pressure-sensitive adhesive tape and has a strong adhesive force to a back sheet. Second
Some tapes use pressure-sensitive tape. In addition, instead of the second pressure-sensitive tape, a diaper has been proposed in which a pressure-sensitive adhesive tape and a releasable film can be attached to a back sheet surface facing the tape when the tape is mounted, and can be detached and attached anywhere on the film. Also, there has been proposed a diaper capable of increasing the strength of the back sheet itself and detaching the back sheet anywhere.
しかしながら、第２感圧テープを用いるテープにおい
て、実際感圧粘着テープを第２感圧テープに取りつける

着することは十分にありうる。その結果おむつの固定が
不十分となり、おむつ本来の性能が十分発揮できない欠
点があった。However, in the tape using the second pressure-sensitive tape, when the pressure-sensitive adhesive tape is actually attached to the second pressure-sensitive tape, it is necessary to be extremely careful to attach it on the second pressure-sensitive tape without fail. In many infants, it is quite possible that the pressure-sensitive adhesive tape is erroneously adhered to a part other than the second pressure-sensitive tape. As a result, the diaper is insufficiently fixed, and there is a disadvantage that the original performance of the diaper cannot be sufficiently exhibited.

になる上、フィルムを貼付した部分のバックシートが硬
くゴワゴワし装着者に不快感をあたえる。Also, in the case of a diaper using a pressure-sensitive adhesive tape and a peelable film instead of the second pressure-sensitive tape, it is necessary to affix the film to a part of the back sheet and discontinuously when manufacturing the diaper. The effect is inferior and expensive, and the back sheet where the film is attached is hard and rough, giving the wearer discomfort.
またバックシート自体に直接感圧テープを付け剥がし
するおむつは、バックシートを必要以上に厚く、強度ア
ップする必要がありおむつ全体が硬くなる欠点を有して
いた。Further, the diaper in which the pressure-sensitive tape is directly attached to and peeled off from the back sheet itself has a disadvantage that the back sheet is unnecessarily thick and needs to be strengthened, and the whole diaper becomes hard.

むつを見出し本発明に到達した。The present inventor has conducted intensive studies to solve the above-mentioned problems, and as a result, by providing a self-adhesive adhesive layer on the surface of the fastening tape base material and on one surface of the liquid-impermeable back sheet,
No need for a pressure-sensitive tape, the fastening tape can be adhered to the correct position of the back sheet, and the present invention has been found by using a diaper that does not harden the back sheet more than necessary. .

つを提供するものである。That is, the present invention relates to a diaper having a liquid-impermeable backsheet constituting one surface of the diaper and a fastening tape provided on both sides of the diaper. A kind of elastomer selected from isoprene-styrene type block copolymer (SIS), styrene-butadiene-styrene type block copolymer (SBS), and styrene-ethylene-butylene-styrene block copolymer (SEBS) Alternatively, a self-adhesive adhesive layer comprising an elastomer obtained by mixing two or more kinds and a tackifier is provided, and the adhesive force of the self-adhesive adhesive is 100 g / 2.
Adhesive strength of 5mm width or less and self-adhesive adhesive coated surface is 200
The present invention provides a diaper that is characterized by having a width of up to 1500 g / 25 mm.

も付け剥がし可能な止着テープを得ることができる。In the diaper of the present invention, since the fastening tape exerts adhesiveness only on the part of the back sheet to which the self-adhesive adhesive is applied, even if the tape is erroneously pressed to an unintended part, The tape can be adhered again to the correct position of the backsheet to which the self-adhesive adhesive has been applied without being adhered. In addition, there is no need to apply a self-adhesive adhesive to the back sheet, and it is not necessary to increase the strength of the back sheet, and to obtain a fastening tape that can be attached and detached anywhere the self-adhesive adhesive is applied.

意図とする所ではない。As the self-adhesive properties of the self-adhesive used in the present invention, the adhesive force is 100 g / 25 mm width or less, and the self-adhesive adhesive coated surface has an adhesive force of 200 to 1500 g / 25 mm width, Preferably, the adhesive force is 10 g / 25 mm width or less, and the adhesive force between the self-adhesive adhesive applied surfaces (hereinafter, referred to as self-adhesive force) is 200 to 1500 g.
/ 25mm width is desirable. If the adhesive strength is larger than 100 g / 25 mm width, stickiness occurs on the coated surface, and the adhesiveness is exhibited also on portions other than the self-adhesive adhesive coated surface, which is not the object of the present invention. If the self-adhesive force is less than 200 g / 25 mm width, it may easily peel off from the coated surface during use, and 1500 g / 25 mm
When the width is larger than mm, when the tape once adhered is peeled off again, a problem such as tearing of the back sheet occurs, which is not intended by the present invention.

クシートが硬くゴワゴワした感じになってしまう。FIG. 3 is a plan view showing an example of the diaper of the present invention, and FIG. 4 is a perspective view when the diaper is worn. The back sheet 6 of the present diaper comprises a uniaxially stretched polyethylene film 4 having a thickness of 40 μm, and a self-adhesive 8 is applied to the surface thereof. The fastening tape 7 has a thickness of 60μ.
The self-adhesive agent 8 is also applied to the surface of the polypropylene film. When the fastening tape 7 is adhered to the back sheet 6 from the state before the attachment tape 7 is adhered (the state shown by the broken line in FIG. 4), the back sheet surface to which the self-adhesive adhesive 8 is applied Will be opposed to The range in which the self-adhesive adhesive 8 is applied to the back sheet 6 here is determined with respect to the backing sheet with the fastening tape
It is preferable to apply the composition to at least a part of the backsheet in the longitudinal direction at least 1/3 or more in the lateral direction from the short side which is not provided. In this case, the coating may be performed in a pattern, and the area at that time may be 30% or more of the coating range. The coating thickness is preferably 100 μm or less. If it exceeds 100μ, the backsheet will be hard and rough.

Therefore, there is no stickiness of the application surface. In addition, since the fastening tape exerts adhesiveness only on the portion of the back sheet to which the self-adhesive adhesive has been applied, the diaper can be correctly fixed without using the fastening tape to an incorrect portion during use. Also, the back sheet after application of the self-adhesive adhesive does not feel hard and rough, and does not give a discomfort to the wearer.
