摘要： A disposable diaper includes a chassis, front and rear waist regions, and a crotch region between the front and rear waist regions and a liquid-absorbent structure extending at least in the crotch region. The chassis includes a pair of first leg elastics, and a pair of second leg elastics. The first leg elastics are arranged so as to be rectilinear in the longitudinal direction. The second leg elastics are arranged at a distance from the longitudinal axis as viewed in the transverse direction larger than a distance from the longitudinal axis at which the first leg elastics are arranged and have rectilinear portions extending in the longitudinal direct at least in a portion of the crotch region close to the front waist region and curved portions spaced apart outwardly from each other from the rear waist region side ends of the rectilinear portions.

摘要： An absorbent article has a longitudinal direction and a lateral direction perpendicular to each other, and includes a waist part along the lateral direction. The waist part includes nonwoven fabric and a plurality of stretchable members. In a state in which the waist part is extended along the lateral direction, an opening is formed in the waist part between stretchable members that are adjacent in the longitudinal direction. A high density region exists longitudinally between the opening and one of the adjacent stretchable members. An external region exists longitudinally between the high density region and another one of the adjacent stretchable members. The high density region has a predetermined lateral length. A density of fibers of the nonwoven fabric in the high density region is larger than in the external region. A part of an edge of the opening includes a portion in which fibers are not fused.

摘要： A disposable diaper provided at least in one of the front and rear waist regions with a pocket adapted to receive and to contain a relatively large amount of body exudates. A chassis includes a main portion, lateral portions lying outboard of the main portion in the transverse direction along which leg elastics extending in a longitudinal direction in the crotch region are provided and a pair of lateral elastic regions formed by folding the both lateral portions. At least in the rear waist region of the front and rear waist regions, waist pocket panels formed contiguously to or separately of elastic belt panels and adapted to connect the inner lateral edge portions of the lateral elastic regions are provided and the elastic belt panels are attached to the outer lateral portions of the lateral elastic regions.

摘要： A disposable wearing article adapted to restrict a possibility that the article might become locally bulky and a packaged assembly of such disposable wearing articles.A diaper (1) has front and rear waist panels (20, 30) defining front and rear waist regions (2, 3), respectively, and an intermediate panel (40) defining parts of the front and rear waist regions and a crotch region (4). The diaper (1) is folded on itself substantially in a flat condition so that inner sheets (24, 34) of the front and rear waist panels (20, 30) may face each other, respectively, and an inner sheet of the intermediate panel (40) may face itself. Specifically, the diaper (1) is folded on itself along a first fold line (81) at least partially corresponding to an imaginary transverse center line (Q-Q). In the diaper (1) having been folded on itself along the first fold line (81), a crotch midsection (83) in the crotch region (3) has a thickness dimension smaller than a thickness dimension of regions (85) lying in the front and rear waist panels (20, 30).
摘要翻译：一种一次性穿着物品，其适于限制物品可能变得局部笨重的可能性以及这种一次性穿着物品的包装组件。尿布（1）具有分别限定前后腰围区域（2,3）的前后腰围片（20,30）和限定前腰围区域和后腰围区域的部分的中间面板（40）和裆下区域（4）。尿布（1）本身基本上以平坦状态折叠，使得前后腰围片（20,30）的内片（24,34）可分别面对，并且中间片的内片（40）可能会面对自己。具体地，尿布（1）沿着第一折线（81）自身折叠，至少部分地对应于假想横向中心线（Q-Q）。在沿着第一折叠线（81）自身折叠的尿布（1）中，裆下区域（3）中的裆部中央部（83）的厚度尺寸小于位于前后腰围板（20,30）。
