A fastening tape (90) of a disposable diaper (10) is provided with a base sheet and a hook sheet. The base sheet has: a joint portion (93) which is joined with a side flap; and a tip end (96). A length (L11) of a product widthwise direction of the tip end (96) is 5 mm to 12 mm. A distance (L12) in a product longitudinal direction between an outside end in the product longitudinal direction of the joint portion and an outside end of the product longitudinal direction of the hook sheet is 2 mm to 12 mm. A length (L13) of the product longitudinal direction at a boundary between the hook sheet and the tip end (96) is two times or more of a distance (L14) in the product longitudinal direction between an inside end of the product longitudinal direction of the base sheet and an inside end of the product longitudinal direction of the hook sheet.

Invention background

The present invention relates to a disposable sail having a fastening tape to securely adhere the fastening front waistline region to the back waistline region.

traditionally; There are known single-use Shad diapers provided with a fixing tape to securely attach a front waistline to a back waistline (eg JOB with reference Japanese Patent No. 50947719). The fixing tape for this patent is supplied with: a base; and a hook member hook member adhered to part of the base surface ©501)20. The al is the two ends of the base Ble for ois the joint portion connection to be connected to the diaper that uses one Hal.

0 of the gal dali (there is an end AT of the base being She of extension unit A) extending to an outer end in the transverse direction than a pad using a single Sad. hook member is provided at the extension unit; an outer end of the transverse direction of the extension unit; where the hook member shall not be placed.” A gripping Unit (ad) is provided to be gripped by the fingers at the time of wearing.

clad 1 because the mounting bar is related to the method of manufacture; As shown in Figure 11 of the patent document 1; a fixing tape is manufactured by cutting a thin film obtained by forming in foil a continuous body characterized by the bases being connected and a continuous body characterized by the members of the hooks being connected. The continuum separation path is a boundary between an end end of an extension unit of one anchor bar and the end nearest the extension unit of another adjacent anchor bar. And there are none

0 waste between one of these mounting strips and the adjacent mounting strip and doy can effectively use the material.

Ad —_ _ Japanese Patent No. EYTY (£0) discloses a single-use Bal diaper with fixing tape; In particular, the Spal single-use nappy is easy to use and super-fastening. Reveals Japanese Patent No. 01 / “Novant with fixing tape; a method for manufacturing an anchor tape; And a single use Bd diaper with tape. More specifically; [oo] of the present invention relates to a fixing tape which is able to increase the adhesion strength between a hook member and a substrate” and a method for manufacturing a fixing tape and a diaper using one $l of the type containing ta pe general description of the invention however; The installation tape as mentioned above had the following problem. in the fixation bar as mentioned above; Fixing tapes are continuously formed; The 0 end shape of an extension unit of a stabilizer bar is the end shape closest to the extension unit of an adjacent AT stabilizer bar. (JB) To make it easier to clamp one end of one of these straps, the adjacent straps are manufactured with more spacers between them to increase the area of that end. However, if the spacers between adjacent straps are increased, the area of the connecting straps part increases Fixation too.Vo generally, the fixation tape consists of a member of higher stiffness compared to a non-woven fabric that forms the top panel of a single use nappy or core or the like which forms an absorbent.The fixation tape is attached to the side seams of the disposable nappy. andy Bad The stiffness of the area where the Jef strap is attached is the stiffness of its circumference The clad The strap is attached to side flaps or similar around the wearer's waistline or leg opening So if Ye gets taller The fixing tape connection part The area of the stiffness lle increases, and there is a fear of a strong feeling of discomfort at the time of wearing. On the cg Al side, if adjacent fixing tapes are manufactured with narrowing of the spacers between them in order to reduce the area of the connection part, the area of the connection decreases The lengthening unit is to be swaddled and there is a concern that it will be difficult to use when wearing it. ‎00Y ‏

_ _ oY Ta, the present invention has been made in view of the problem described above; One of the purposes of the present invention is to provide a disposable diaper with a fastening tape that can improve its usability at the time of wearing while preventing the feeling of discomfort at the time of wearing. It is summarized that the disposable diaper of the present disclosure (Hal© single use diaper 01) has: front waistline area; back pad line area; Crotch 07 is between the front waistline and the back waistline; Longitudinal product direction directed from the front waistline to the back waistline; and product in the transverse direction perpendicular to the direction of the longitudinal product; an absorber oriented along the bifurcation zone and extending at least one of the anterior 0 waistline and posterior waistline regions; Side flap hem runs along front waistline; branching area back waistline; It is placed outside the product in the transversal direction more than the absorbent; f a pair of securing straps which extend out transversely from the back waistline of the side hem and are securely attached to the front waistline; Vo where the mounting bar includes: base sheet coupled to side skirt; a hook sheet in which a set of coupling members mesh with the front waistline area is provided and is attached to the base plate; for base plate: connection part to be attached to side skirt; a 976 end that extends outward from the product in the transverse direction further than the hook plate; The length of the product in the transverse direction end end 97 is from © mm to VY mm; The distance in 0 longitudinal product direction between the outer end of the longitudinal product direction of the connecting part and the outer end of the longitudinal product direction of the hook plate is from ¥ mm to VY mm; The length in the direction of the longitudinal product at the boundary between the hook plate and the end end is 97 times or more the distance that in the direction of the longitudinal product between the inner end of the direction of the longitudinal product of the base plate and the inner end of the direction of the longitudinal product of the hook plate; The hook plate extends outward in the longitudinal direction of the product at about 00Y
