Problems solved by technology

Since the floating piece is formed on the lateral inner side of the leg elastic member, if the leg elastic member moves, the floating piece also moves, causing the problem that the floating piece is separated from the wearer without contact, or the shape of the opening of the floating piece is deformed.

[0070] Figure 1 to Figure 8 Shows the first embodiment. figure 1 It is a figure which shows the wearing state of the diaper 1. As shown in the figure, the diaper of this embodiment is a so-called pull-on diaper. The diaper 1 is formed into a panty shape by a base 2, which includes a front waist area 3, a back waist area 4, and a crotch area 5 located between the front and rear waist areas 3 and 4. The direction from the front waist region 3 through the crotch region 5 to the rear waist region 4 is referred to as the longitudinal direction Y, and the direction orthogonal thereto is referred to as the lateral direction X.

[0071] The base 2 includes an inner face sheet 6 forming an inner face on the body side, an outer face sheet 7 forming an outer face on the clothing side, and front and rear flaps 8 and 9 mounted on the front and rear waist regions 3 and 4 of the inner and outer face sheets 6 and 7. The front and rear flaps 8 and 9 are formed of elastic sheets that can expand...

[0095] Picture 9 This is a developed plan view of the diaper 1 of the second embodiment, and for ease of understanding, the description of the leak-proof cuffs 35 and 36 is omitted. In this embodiment, the same constituent elements as those in the first embodiment use the same symbols as in the first embodiment, and detailed descriptions are omitted. The present embodiment is characterized in that communication paths 48 and 49 that communicate the inner and outer sides of the lateral direction X are formed in the first joint portions 30 and 31. A plurality of communication paths 48 and 49 are intermittently formed at least on the front waistline region 3 side of the horizontal center line Q-Q. By forming the communication passages 48 and 49 in this way, the urine excreted to the front communication portion 24 flows out to the outside of the first joint portion 30 and 31 in the lateral direction X, and the liquid absorbing structure 15 can also be absorbed on the outside. Sinc...

Abstract

Misalignment between a connecting part formed on a separation sheet that separates the chassis of an absorbent article from the excretion position can be controlled. A liquid-absorbing structure (15) is formed between inner and outer sheets (6, 7). A separation sheet (18) is formed on the chassis side of the inner sheet (6). The two side parts (21, 22) of the separation sheet (18) are bonded to the inner sheet (6) via first bonding parts (30, 31). The first bonding parts (30, 31) extend continuously in the longitudinal direction Y and are roughly superimposed on the liquid-absorbing structure (15) in the thickness direction. Leakage-prevention cuffs (35, 36) formed on the chassis side of the separation sheet (18) are bonded to the inner sheet (6) via second bonding parts (41, 42) positioned outside the separation sheet 18 in the horizontal direction X and are also bonded to the separation sheet (18) via a third bonding part (50) in the front waist area (3) and are bonded to the separation sheet (18) via a fourth bonding area (51) in the rear waist area (4).

Description

Technical field [0001] The present invention relates to absorbent articles, in particular to absorbent articles such as disposable diapers, defecation training pants, and incontinence underwear. Background technique [0002] Conventionally, as a disposable diaper having a sheet formed with an opening through which feces and urine pass, for example, the disposable diaper disclosed in Japanese Patent Application Laid-Open No. 9-510385 (Patent Document 1) is known. According to Patent Document 1, the diaper has an inner sheet, an outer sheet, and a floating sheet arranged on the inner surface of the inner sheet on the body side. The floating sheet is formed with front and rear openings through which feces and urine pass. An elastic member for the floating sheet is attached in an elongated state along the front and rear openings in the longitudinal direction, and the elastic member is contracted to separate the floating sheet from the base and contact the wearer's skin. Stool and u...
