Problems solved by technology

[0006] However, since the absorbent pad is arranged in the area where the absorbent body does not exist in the diaper, when the size of the non-existing area where the absorbent body does not exist is different from the size of the absorbent pad, that is, the size of the absorbent pad is larger than that of the non-absorbent pad. In the case where the presence area is small, excrement is not absorbed and may adhere to the wearer's body in the non-existence area where there is no absorbent pad. On the other hand, the size of the absorbent pad is larger than the non-existence area In the case where part of the absorbent pad covers the gathers of the diaper main body, it may cause side leakage of excrement from the diaper main body

[0061] Figure 7 It is a perspective view of the absorbent pad 18 of the second embodiment of the diaper 10 of the present invention, Figure 8 is the second embodiment with Image 6 The same cutaway view. The basic structure other than the absorbent pad 18 of the diaper 10 of this embodiment is substantially the same as the structure of 1st Embodiment, Therefore It abbreviate|omits.

[0062] In this embodiment, the both side edge parts 18c and 18d of the absorbent pad 18 are arrange|positioned in the excrement storage space S in the state bent. Specifically, both side edge parts 18c and 18d of the absorbent pad 18 bent toward the skin-opposite side are arranged in a state of being in contact with the inner surfaces of the both side elastic parts 43 . In the case of the above-mentioned form, in the unfolded state of the diaper 10, the side edge portions 18c, 18d of the absorbent pad 18 do not protrude inwardly from the inner side edges 43a of the both side elastic portions ...

[0064] Figure 9 It is a perspective view of the absorbent pad 18 of the third embodiment of the diaper 10 of the present invention, Figure 10 is the third embodiment with Image 6 The same cutaway view. Since the basic structure other than the absorbent pad 18 of the diaper 10 of this embodiment is substantially the same as the structure of 1st Embodiment, it omits.

[0065] In this embodiment, the absorbent pad 18 has a pair of barrier cuffs 70, 71 extending in the longitudinal direction Y on both sides thereof. The barrier cuffs 70, 71 are composed of the following components: the side edges of the front and back sheets 22, 23 forming the absorbent pad 18; a plurality of elastic elements 72, 73 capable of It is elongatedly fixed to the two side edges. Also, although not shown, part of the front and rear end portions or both side portions of the barrier cuffs 70 and 71 of the absorbent pad 18 are fixed to the inner surfaces of the both side elastic portions 43 of the cr...

Abstract

Provided is a disposable wear article which comprises a relatively thin body-fluid absorber extending from the front and back waist regions to the crotch region, and, even when a detachable absorbent pad is disposed in the disposable wear article, the aesthetic appearance of the disposable wear article is not harmed and the user does not experience a stiff wearing sensation. At least one of the front and back end parts (12A, 12B) of a crotch main body (12) is attached to a non-skin facing surface of an elastic waist panel (11) by means of joining regions (55, 56) not including a central section in the transverse direction of the crotch main body (12). In addition, central space sections (67, 68) are formed between the elastic waist panel (11) and the crotch main body (12) in non-joining regions (63, 64) positioned in the central section of the crotch main body (12). The body fluid absorber (42) has a sheet shape formed by highly absorbent polymer particles being encapsulated with a liquid permeable sheet, and at least one of the front and back end edge sections (42a, 42b) of the body fluid absorber (42) is positioned in the central space sections (67, 68).

Description

technical field [0001] The present invention relates to disposable wearing articles, and more particularly, to disposable wearing articles such as disposable diapers, disposable toilet training pants, disposable incontinence pants, and disposable sanitary napkins having detachable absorbent pads. Background technique [0002] Conventionally, disposable diapers having absorbent pads are known. For example, Patent Document 1 discloses a disposable wearing article having an absorbent pad in the front waist region detachably attached to the skin-opposite side of the diaper main body by means of a fixing mechanism. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2006-115991 [0005] According to the wearing article disclosed in Patent Document 1, the absorbent body of the diaper is located in the front waist region, and only the absorbent pad is disposed in the rear waist region without the absorbent body, so that the absorbent pad does n...
