Problems solved by technology

In addition, the rise of this disposable diaper is longer, which is easy to be exposed from pants and skirts
Disposable diapers made of non-woven fabrics are inferior to cloth underwear in terms of softness and moisture absorption. Therefore, if the area covered by the wearer is large, the wearing feeling is not good
These diapers are especially not suitable for active adults

no. 2 approach

[0099] Next, the disposable underwear which is another embodiment of this invention is demonstrated.

[0100] Figure 11 It is a developed view of the stretched elastic member of the disposable diaper 30 of this embodiment. Components having the same configurations and functions as those of the above-mentioned embodiments are given the same reference numerals, or redundant descriptions are appropriately omitted. The disposable diaper 30 of this embodiment is the same as the disposable diaper 1 of the above-mentioned embodiment except that the shapes of the inelastic regions P31, P32, and P33 are different.

[0101] The disposable diaper 30 of the present embodiment is different from the disposable diaper 1 of the aforementioned embodiment. The apex of the triangle in the inelastic region P31 is located at the lower part of the center of the first leg circumference elastic member 13, and the first leg circumference elastic member 13 And the upper part of each center of the wa...

[0107] Next, the disposable underwear which is still another embodiment of this invention is demonstrated.

[0108] Figure 12 It is a development view in the state in which the elastic member of the disposable diaper 60 of this embodiment was stretched. The same code|symbol is attached|subjected to the component which has the structure and function similar to the disposable diaper 1 of embodiment mentioned above, or the overlapping description is abbreviate|omitted suitably. The disposable diaper 60 of the present embodiment is compared with the disposable diaper 1 of the foregoing embodiment, the shape of the lower end edge 66 of the abdominal side member 62 and the lower end edge 67 of the back side member 63 are different, and the waist circumference of the abdominal side member 62 is different. The number of components of the elastic member 12 is different, the first leg circumference elastic member 68 and the second leg circumference elastic member 69 are different, and...

no. 4 approach

[0114] Next, the disposable underwear which is still another embodiment of this invention is demonstrated.

[0115] Figure 13 It is a developed view of the stretched elastic member of the disposable diaper 70 of this embodiment. The same code|symbol is attached|subjected to the component which has the structure and function similar to the disposable diaper 1 of embodiment mentioned above, or the overlapping description is abbreviate|omitted suitably. Such as Figure 4 As shown, the shape of the abdomen side member 2 in the stretched state of the disposable diaper 1 of the aforementioned embodiment is such that one long side of the rectangle is concaved inward to form a substantially trapezoid. In contrast, as Figure 13 As shown, the abdomen side member 72 of the disposable diaper 70 of this embodiment is substantially rectangular.

[0116] Such as Figure 13 As shown, the disposable diaper 70 of the present embodiment includes an abdominal member 72 , a back member 3 and ...

Abstract

Provided is a disposable undergarment that has a short rise, does not exert excessive pressure around the navel of a wearer, and has a stable wearing position. This disposable undergarment (1) is provided with: an abdominal-side member (2) and a back-side member (3) that are joined to each other at joining portions (5a, 5b); a crotch member (4) that is joined so as to span between center portions (2c, 3c) of the abdominal-side member (2) and the back-side member (3); a waist opening (6); left and right leg openings (9a, 9b); and a first elastic member (13) that extends upward toward an upper edge (7) from the bottom portions of the joining portions (5a, 5b) of the abdominal-side member (2) to the center in the waist direction. The disposable undergarment (1) is shaped so as to widen from the waist opening (6) toward the left and right leg openings (9a, 9b) below, and the center (7a) of the upper edge (7) of the abdominal-side member (2) is lower than the upper edge (8) of the back-side member (3).

Description

technical field [0001] The present invention relates to disposable underpants, especially panty-type disposable diapers, pad support pants, etc., and a method for manufacturing such disposable underpants. Background technique [0002] Disposable underpants such as well-known underpants-type disposable diapers and liner support pants in the past have a long rise. Roughly horizontal around the navel. For example, Patent Document 1 discloses a pant-type disposable diaper. When the disposable diaper worn by a person sitting on the floor is viewed from the side, the waist opening is positioned approximately horizontally around the navel of the wearer. . [0003] patent documents [0004] Patent Document 1: Japanese Patent No. 3916878 [0005] However, when wearing the disposable diapers, the waist opening is positioned approximately horizontally around the navel of the wearer because the waist opening tightens around the navel without bones to support the wearing position, so...
