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 top view of the same crotch body 12. Also, for illustrative purposes, with Figure 5 Similarly, since the liquid-absorbent structure 40 is shown by the phantom line, and 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 center 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 portion 41 can be set to increase toward the center of the crotch region 15, and the center of the crotch region 15 can be broug...

Abstract

Provided is a disposable wearing article improved so that the tensile stress in the middle of the crotch region as well as in the vicinity thereof can be set to be higher than in the other regions without adjusting the number and thickness of the leg elastic elements and a relatively large body waist retaining space can be formed to protect the wearer's skin from being soiled with body waste. A crotch region 15 is provided in both lateral portions thereof with a plurality of leg elastic elements 50, 51 extending in a longitudinal direction Y wherein the respective outermost elastic elements 51 are laid so as to define concave curves in a middle zone of the crotch region 15 and in the vicinity thereof.

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...
