no. 1 Embodiment approach

[0041] The pull-on diaper 10 is demonstrated as 1st Embodiment of the disposable pull-on underwear of this invention.

[0042] figure 1 It is a figure which shows the pull-on diaper 10 of 1st Embodiment.

[0043] figure 2 It is the figure which developed the pull-on diaper 10 of 1st Embodiment in planar form.

[0044] image 3 It is a figure explaining the 1st leg circumference elastic body 103c, the 2nd leg circumference elastic body 103d, and the planned cutting line C of the pull-on diaper 10 which concerns on 1st Embodiment.

[0045] For easy understanding, in Figure 1 ~ Figure 3 In each figure shown below and below, the elastic body 103 described later is shown in a stretched state (a state in which no contraction force is exhibited). In addition, in figure 2 In each of the figures shown below, for easy understanding, the width direction (the wearer's waist direction, the left-right direction) of the unfolded pull-on diaper is used as the X-axis, the front-rear d...

no. 2 Embodiment approach

[0111] Figure 8 It is a figure which shows the pull-on diaper 20 of 2nd Embodiment.

[0112] Figure 9 It is the figure which developed the pull-on diaper 20 of 2nd Embodiment in planar shape.

[0113] Figure 10 It is a figure explaining the 1st leg circumference elastic body 203c, the 2nd leg circumference elastic body 203d, and the planned cutting line C of the pull-on diaper 20 of 2nd Embodiment.

[0114] In the pull-on diaper 20 which is the second embodiment of the disposable pull-on underwear of the present invention, the plurality of linear first leg elastic bodies 203c and the second leg elastic bodies 203d forming the leg gathers 29 are arranged. The shape is different from the above-mentioned first embodiment, but is the same aspect as the underpants-type diaper 10 of the above-mentioned first embodiment except that. Therefore, the same reference numerals are assigned to the same functions as those in the first embodiment described above, or the same reference ...

no. 3 Embodiment approach

[0125] Figure 11It is the figure which developed the panty type pad support 30 of 3rd Embodiment in a planar form.

[0126] The panty-type pad support 30 of the third embodiment of the disposable panty-type underwear of the present invention has a crotch part (crotch part) 33 instead of the absorbent part 13, which is different from the above-mentioned first embodiment. Other than that, it is about the same form as the pull-on diaper 10 of 1st Embodiment. Therefore, the same reference numerals are assigned to the same functions as those in the first embodiment described above, or the same reference numerals are appended at the end, and overlapping descriptions are appropriately omitted.

[0127] The panty-type pad support 30 of this embodiment has an abdominal member 11, a back member 12, a crotch member (crotch member) 33, and has a waist gather formed at the waist of the wearer. This panty-type pad support 30 can arrange a general-purpose rectangular-shaped absorbent arti...

Abstract

The present invention provides disposable panty-type underwear which is easy to wear, has high fit to the wearer's body, and can be manufactured with a small amount of material, and a manufacturing method thereof. The manufacturing method of disposable panty-type underwear (10) is characterized by comprising: forming a laminated body in which each elastic body (103) is bonded between a net-shaped inner surface sheet (101) and an outer surface sheet (102) The process of (100A), along the crotch side end edge (11a, 12a) shared by the abdominal part (11) and the back side part (12) in the conveying direction of the net, the predetermined line of cutting (C) that is periodically continuous is paired. The process of cutting the laminated body (100A), the process of bridging the crotch part (13) at the two central parts of the abdominal part (11) and the back side part (12) of each cycle, the crotch part (13) is The jointed continuum (100B) is bent, and the two ends (16, 16) perpendicular to the conveying direction of the net are joined and cut according to each period; the planned cutting line (C) of each period includes: Two end lines (11b, 11b, 12b, 12b) parallel to the feeding direction of the net, a pair of inclined lines (11c, 11, 12c, 12c) inclined from the two end lines to the center and to the ventral part (11) side, the two The central line (11d, 12d) connecting the oblique lines.

Description

technical field [0001] The present invention relates to disposable undergarments such as an underpants-type diaper and an underpants-type pad support, and a manufacturing method thereof. Background technique [0002] Existing underpants-type diapers and padholders (padholders) are formed by removing a part from the tape-shaped fabric forming the outer package in a continuous manufacturing process to form through-holes and incisions for inserting the wearer's feet. (For example, see Patent Document 1). [0003] In addition, there are also known panty-type diapers and pad holders in which a rectangular abdominal member and a rectangular back member are arranged such that a crotch member is connected (for example, Patent Document 2). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2009-118986 [0007] Patent Document 2: Japanese Patent Laid-Open No. 2011-78646 Contents of the invention [0008] However, th...
