Description of the Related Art Conventionally, as a pants-type disposable diaper, for example, as disclosed in Japanese Patent Laid-Open No. 57-77304, a flat type diaper is folded in two at the crotch, and a front body and a back body are formed. It has been proposed that the side flaps on the left and right sides of the side flap are joined to form a waist opening and a pair of leg openings.
Such a pants-type disposable diaper can be attached and detached by a wearer, and there is an increasing demand for the infant to leave the diaper or for an adult such as an incontinent person.

るいは面積等を規定することが開示されている。Such a pants-type disposable diaper needs to be breathable in order to prevent the wearer from getting stuffy due to water vapor such as sweat or urine, and the joint portion is torn carelessly when worn. In addition, there is a need for easy tear-off separation at the time of disposal. Regarding the formation of a joint suitable for such a purpose, Japanese Utility Model Publication No. 7-54244, Japanese Utility Model Publication No. 8-7850, Japanese Utility Model Publication No. 6-31721, and Japanese Utility Model Publication No. 6-5062.

傷つけるという問題点を有している。However, in the above-mentioned pants-type disposable diaper, generally, the side flaps are joined at their side edges by press-melting the side flaps formed of a non-woven fabric or a film made of a heat-fusible resin. It is performed by heat sealing such as ultrasonic melting, and the resin in the heat-sealed portion is melted and solidified to form a hard joint, so a diaper having such a hard joint was worn. In this case, there is a problem in that the joint is irritated to the skin to give the wearer an uncomfortable feeling and sometimes to hurt the wearer's skin.

ロールすることが難しいものであった。In order to improve this problem, if the heat sealing process is reduced to reduce the melting of the resin, the formation of a hard joint is improved, but the joint strength is lowered and the joint is worn when the diaper is worn. Is more likely to be torn, while strengthening the heat seal process improves the strength of the joint,
Since the joint becomes hard, it is difficult to control the treatment conditions within an appropriate range.

とができるものである。BEST MODE FOR CARRYING OUT THE INVENTION In the pants-type disposable diaper of the present invention, the joints of both side edges of the front and rear bodies of the member forming the pants are formed by a large number of joint lines arranged at predetermined intervals in the longitudinal direction. The joint line has a length dimension that is long in a direction intersecting the longitudinal direction of the joint portion and a height dimension that is shorter than the length dimension, and the waist circumference opening vicinity and the legs. The array spacing at the joint near the surrounding opening is closer than the array spacing at the other joints. That is, the pants-type disposable diaper of the present invention having such a configuration has the waist-opening vicinity and the leg-opening opening even when the side edges are melted by heat sealing to form a joint. By closely arranging the joining lines in the narrow part in the vicinity, the strength of the joining part when the diaper is worn is maintained, and the arrangement interval of the joining lines in the part other than the vicinity of the opening is made as wide as possible. By reducing the number of joint lines, the joint is softened, so that the joint does not irritate the wearer's skin and has an excellent wearing feeling. The joint portion is not torn carelessly inside, and the joint portion can be easily peeled off at the time of disposal.

のものを含む。In this case, the length of the joining line is 3 to 15 m.
m, and the height dimension is preferably 0.4 to 5 mm. If the length is less than 3 mm, the strength of the joint will decrease and it will be easily torn when worn, while if it exceeds 15 mm, the diaper will look unattractive and it will be worn when clothing is worn over the diaper. Hard to let
Further, when the height dimension is less than 0.4 mm, the strength of the joint decreases, while when it exceeds 5 mm, the joint becomes stiff, which easily irritates the skin of the wearer, and the joint is damaged when the diaper is discarded. It will be difficult to peel it off. In the present invention, the joining line refers to a pattern formed on a portion of the pants member that has been heat-sealed, and the pants member is in a state of being melt-bonded and pants by excessive heat-sealing treatment. It includes those in which the member is melted to form the voids.

˜1.5 mm, and it is preferable that the arrangement interval of the joining lines in the other joining portions is 1 to 7 mm. If the spacing between the joining lines at the joints near the waist opening and the leg openings is less than 0.5 mm, the joint becomes stiff, making it uncomfortable to wear and making it difficult to peel the joint off when disposing of the diaper. On the other hand, when the arrangement interval becomes wider than 1.5 mm, the strength of the joint portion decreases. Further, the arrangement interval of the joining lines in the joining portion other than the vicinity of the opening is 1
If it is less than mm, the arrangement interval of the joining lines becomes dense and the wearing feeling becomes poor, while if the arrangement interval becomes wider than 7 mm, the joining strength decreases. Further, in each of the joints near the opening and the other joints, the joint lines may be arranged at equal intervals or may be arranged at different intervals.

Specifically, a so-called integral type diaper composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber arranged between these two sheets is used. The pants-type disposable diaper can be formed by folding and then joining the side edges of the front and rear side flaps. Alternatively, a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent main body composed of an absorbent body arranged between these two sheets, and the absorbent main body is joined to the wearer. A so-called two-piece type diaper consisting of an outer sheet to be applied and held is folded with the absorbent body inside and the side flaps of the front and rear body parts of the outer sheet are joined together to form a pants-type disposable diaper. You can also do it.
