no. 1 Embodiment approach

[0038] As a first embodiment of the disposable underwear type underwear of the present invention, a underwear type diaper 10 will be described.

[0039] figure 1 It is a figure which shows the underpants type diaper 10 of 1st Embodiment.

[0040] figure 2 It is a figure which expanded the panty type diaper 10 of 1st Embodiment in a planar shape.

[0041] image 3 It is a figure explaining the 1st leg circumference elastic body 103c, the 2nd leg circumference elastic body 103d, and the planned cut line C of the underwear type diaper 10 of 1st Embodiment.

[0042] For easy understanding, in Figure 1 ~ Figure 3 In each figure shown below, the elastic body 103 described later is shown in an extended state (a state in which no contractile force is exhibited). In addition, in figure 2 In the figures shown below, for ease of understanding, the width direction (waist direction, left and right direction of the wearer) of the unfolded panty diaper is used as the X axis, the front and back di...

no. 2 Embodiment approach

[0108] Figure 8 It is a figure which shows the panty type diaper 20 of 2nd Embodiment.

[0109] Picture 9 It is a figure which expanded the panty type diaper 20 of 2nd Embodiment in a planar shape.

[0110] Picture 10 It is a figure explaining the 1st leg circumference elastic body 203c, the 2nd leg circumference elastic body 203d, and the planned cut line C of the underpants-type diaper 20 of 2nd Embodiment.

[0111] In the panty-type diaper 20 as the second embodiment of the disposable panty-type underwear of the present invention, a plurality of linear first leg elastics 203c and second leg elastics 203d forming the leg gathers 29 are arranged The shape is different from the aforementioned first embodiment, except that it is the same aspect as the pant-type diaper 10 of the aforementioned first embodiment. Therefore, parts that perform the same functions as those of the first embodiment described above are given the same symbols or appended with the same symbols, and repeated ...

no. 3 Embodiment approach

[0122] Picture 11 It is a figure which unfolds the panty type cushion support 30 of 3rd Embodiment in a planar shape.

[0123] The panty-type cushion support 30, which is the third embodiment of the disposable panty-type underwear of the present invention, has a crotch member (crotch member) 33 instead of the absorbent member 13, and is different from the above-mentioned first embodiment in this point. Except for this, it is a form substantially the same as the underpants type diaper 10 of 1st Embodiment. Therefore, parts that perform the same functions as those of the first embodiment described above are given the same symbols or appended with the same symbols, and repeated descriptions are appropriately omitted.

[0124] The panty-type cushion support 30 of the present embodiment includes an abdominal member 11, a back member 12, a crotch member (crotch member) 33, and has waist gathers formed on the waist of the wearer. The panty-type pad support 30 can be used by arranging ab...

Abstract

Provided are disposable pant-type underwear, and a manufacturing method therefor, the disposable pant-type underwear being easy to wear, having a good fit to the body of the wearer, and requiring little material for production. The method for manufacturing disposable pant-type underwear (10) is characterized by comprising: a step for forming a layered body (100A) in which elastic bodies (103) are bonded between a webbed inner-surface sheet (101) and an outer-surface sheet (102); a step for cutting the layered body (100A) along a cutting guidance line (C) along which crotch-side edges (11a, 12a) shared by a ventral member (11) and a dorsal member (12) are periodically continuous in the web flow direction; a step for positioning, in each period, a crotch member (13) so as to span the central portion of both the ventral member (11) and the dorsal member (12) and bonding the crotch member thereto; and a step for folding a continuous body (100B) in which the crotch members (13) have been bonded, and, for each individual period, bonding the continuous body (100B) at both ends (16, 16) that are perpendicular to the direction in which the web flows, and cutting along both ends (16, 16). The method is further characterized by the cutting guidance line (C) for each period including: two end lines (11b, 11b, 12b, 12b) that are parallel to the direction in which the web flows; a pair of inclined lines (11c, 11c, 12c, 12c) that are inclined towards the ventral member (11) from the two end lines toward the center; and central lines (11d, 12d) that connect both inclined lines.

Description

Technical field [0001] The present invention relates to disposable panty-type underwear such as panty-type diapers and panty-type pad supports, and a method of manufacturing the same. Background technique [0002] Existing panty-type diapers and padholders are formed by removing a part of the band-shaped fabric forming the outer package body in the continuous manufacturing process to form through holes and cutouts for the foot openings of the wearer's feet (For example, see Patent Document 1). [0003] In addition, there is also known a panty-type diaper and a pad support formed by connecting a rectangular abdominal member and a rectangular back member to a crotch member (for example, Patent Document 2). [0004] Prior art literature [0005] Patent literature [0006] Patent Document 1: Japanese Patent Application Publication No. 2009-118986 [0007] Patent Document 2: Japanese Patent Application Publication No. 2011-78646 Summary of the invention [0008] However, the disposable pant...
