Problems solved by technology

In addition, in order to locally increase the elongation stress of the leg elastic elements, it is also considered to adjust the number and elongation stress of the whole leg elastic elements, but in this case, the entire side elastic part will excessively tighten the wearer's leg , may cause discomfort, and in addition, in the case of locally increasing the number of elastic elements, a required manufacturing process is required

[0027] figure 1 It is a perspective view of a disposable diaper 10 shown as an example of the disposable wearing article of the present invention, figure 2 It is a partially cutaway plan view viewed from the inner surface of the diaper 10 in a state where the seam portion 18 is peeled off and stretched in the front-rear direction, image 3 (a) is along figure 2 The sectional view of the line III-III, image 3 (b) is in the wearing state of the diaper 10 and image 3 (a) The same sectional view, Figure 4 is along figure 2 The sectional view of the IV-IV line, Figure 5 is a plan view of the crotch body 12 . exist Figure 5 In the figure, for convenience of description, the liquid-absorbent structure 40 is shown by phantom lines.

[0028] Such as figure 1 and 2 As shown, the disposable diaper 10 includes: a longitudinal direction Y and a transverse direction X perpendicular thereto; an imaginary central line P-P that divides the width dimension of the transverse di...

[0055] Figure 7 represent the second embodiment of the present invention and Figure 5 The same top view of the crotch body 12. Also, for illustrative purposes, with Figure 5 Similarly, the liquid-absorbent structure 40 is shown by the phantom line, and since the basic structure of the diaper 10 is the same as that of 1st Embodiment, only a different point is demonstrated below.

[0056] Such as Figure 7 As shown, in the second embodiment, the separation dimension of the second leg elastic elements 51 in the transverse direction X gradually becomes smaller as it approaches the central part of the crotch region 15, and the innermost portion of the second leg elastic elements 51 Among the elastic elements, the elastic elements at the concave portion 53 are in the closest state to each other. In this structure, the elongation stress of the side elastic parts 41 can be set to increase toward the center of the crotch region 15, and the center of the crotch region 15 can be b...

Abstract

A disposable wearing article wherein the tensile stress in the center section of a crotch region and in the vicinity of the center section can be set at a level higher than that in other regions without adjusting the number, thickness, etc. of leg elastic elements and wherein the adhesion of excreta to the skin can be avoided by forming a greater excreta containing space. Lines of leg elastic elements (50, 51) extending in the longitudinal direction (Y) are disposed on both sides of a crotch region (15), and the elastic elements (51) located on the outer sides from among the elastic elements, which form the lines of leg elastic elements (50, 51), have a curved shape which is recessed in the center section of the crotch region (15) in the longitudinal direction (Y) and is also recessed in the vicinity of the center section.

Description

technical field [0001] The present invention relates to disposable wearing articles, in particular to disposable diapers, disposable toilet training pants, disposable incontinence shorts, disposable menstrual shorts, etc. Wearing items. Background technique [0002] Conventionally, wearing articles are known that have side elastic portions that come into contact with the wearer's leg circumference. For example, Patent Document 1 discloses a disposable wearing article having a pair of side elastic portions on both sides of a liquid-absorbent structure. The pair of side elastic portions extend in the longitudinal direction of the wearing article and are arranged in a plurality of or banded leg elastics. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2000-254176 [0005] In wearing articles such as disposable diapers, in order to prevent side leakage of excrement, the central part of the crotch region and its vicinity require a highe...
