Description

  The present invention relates to a disposable diaper having a fastening tape, and more particularly, the present invention relates to a disposable diaper having a fastening tape that does not come off a side flap during use.

  Disposable diapers are basically formed from a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between these two sheets, and excreted urine excreted when worn. It is structured to hold the substance on the absorbent body via a liquid-permeable top sheet and prevent the excrement from leaking out of the diaper by the liquid-impermeable back sheet, suitable for its use Various types such as a deployment type and a pants type have been proposed so that they can be used for a wide range of uses, including infants and other adult incontinents.

  The unfoldable disposable diaper generally has a front tape for disposing the fastening tape on both sides of the left and right side flaps of the back body and detachably engaging the fastening tape on the back sheet surface of the front body. The diaper is attached to the wearer by arranging the zone and joining the fastening tape to the front tape. Fastening tapes of such unfoldable disposable diapers are usually attached one by one or several on the left and right. The former is often used for newborns and infants, and the latter is an adult disposable diaper. Many are seen.

  As a combination of the fastening tape and the front tape, a combination of a fastening tape having a hook material of a mechanical fastener and a front tape having a loop material engageable with the hook material is widely used. Disposable diapers in which various devices have been applied to the front tape have been disclosed (Patent Document 1, Patent Document 2, and Patent Document 3).

In general, a fastening tape is attached by sandwiching and fixing between two sheets (for example, a top sheet and a back sheet) that form a side flap, by applying an adhesive on one or both sides of a base sheet. At the same time, the two sheets are bonded with an adhesive to form a side flap.
However, when the caregiver wears an unfoldable disposable diaper to an adult who cannot move the body freely, a fastening extended from the side flap on the back body side to adjust the position of the back body area of the disposable diaper The tape may be gripped and pulled strongly. At this time, since the portion where the fastening tape is sandwiched is composed of three sheets including the fastening tape with respect to the side flap composed of two sheets, it is adjacent to the portion where the fastening tape is attached. The thickness and strength of the sheet are different from those of the inner region, and distortion tends to occur starting from the inner region adjacent to the portion where the fastening tape is attached, and the side flaps may be broken.

In order to prevent such side flaps from being broken, a disposable diaper having improved adhesive strength between a side sheet and a surface sheet constituting the side flap is disclosed (Patent Document 4).
