摘要： An outer covering sheet (4) of a pants-type disposable diaper (1) has a front part and a back part (403) to be positioned on a front side and a back side of a wearer, and a middle part lying between the front and back parts. An absorbent body (20) is attached on the outer covering sheet (4) to absorb excrement from the wearer. Both end portions of the absorbent body, positioned in the front part and the back part (403), are folded toward the inner surface (40) of the outer covering sheet (4) and bonded on the inner surface (40). It is therefore possible to prevent skin of the wearer from being irritated by edges (241) of the end portions of the absorbent body (20) when the disposable diaper (1) is worn.

摘要： In an outer covering sheet of an absorbent product, first, second and third adhesive layer elements each extending in a left-right direction are formed on a second covering sheet by spiral spray application. Each of these adhesive layer elements has wide width parts and narrow width parts which are continuous with the wide width parts, respectively. Therefore, hot melt adhesive can be stably discharged across the entire length of the adhesive layer element, unlike in the case where only wide width parts are formed intermittently. As the result, it is possible to obtain the outer covering sheet which is a sheet member having the adhesive layer elements with desired shapes where unevenness is decreased. And in the absorbent product which is manufactured with use of the sheet member, comfort level of the wearer can be prevented from decreasing due to unevenness of thickness of the adhesive layer elements.

摘要翻译： 在吸收性物品的外包覆片中，通过螺旋喷涂法在第二覆盖片上形成各自沿左右方向延伸的第一，第二和第三粘合剂层元件。 这些粘合剂层元件中的每一个分别具有与宽宽度部分连续的宽宽度部分和窄宽度部分。 因此，与仅间断地形成宽幅部的情况不同，热熔粘合剂能够在粘合剂层元件的整个长度上稳定地排出。 结果，可以获得作为具有不均匀性降低的所需形状的粘合剂层元件的片状构件的外覆盖片。 并且在使用片状部件制造的吸收性物品中，由于粘合剂层元件的厚度不均匀性，可以防止穿着者的舒适度下降。

摘要： Disposable pants enabling the firm connection of a crotch region to a front abdominal region while securing the stretchability of the front abdominal region in a pants structure in which the crotch region and the front abdominal region formed separately from each other are connected to each other. The disposable pants (1) comprise both functions of pants and diaper, and a left front abdominal region (2a) and a right front abdominal region (2b) can be stretched to right and left sides by breaking right and left breakage parts (17b, 17a). Adhering pieces (22a, 22b) detachably fitted to the adhering parts (23a, 23b) of a center front abdominal region (2c) are fitted to the right front abdominal region (2b) and the left front abdominal region (2a). The crotch region (4) on which an absorbent (43) is fitted is connected to the center front abdominal region (2c) by using sheet materials (45a, 45b) so that the stretchability of the center front abdominal region (2c) by an elastic member (19c) is not obstructed.

摘要： In an absorbent product (1), each of a pair of side wall parts 34 has two side wall end parts (341) bonded on both end portions of a bonded part (33) and a standing part (342) standing up from the main body part (2) between the two side wall end parts (341). The side wall part (34) is folded outwardly at an inner edge of the bonded part (33) and further folded inwardly. Each side wall end part (341) has a bonded section (3411) and a half standing part (3412) which is continuous from the standing part (342). The half standing part (3412) stands up from the main body part (2) lower than the standing part (342) and fits the vicinity of wearer's crotch in wearing. Thus, it is possible to prevent side leakage from the vicinity of end portions in a longitudinal direction of the absorbent product (1).
