Disposable diaper

Номер: US20130110065A1
Автор: Emi Amano, Kenji Nakaoka, Yuki Takahashi
Принадлежит: Livedo Corp

A pants-type disposable diaper has an outer covering sheet formed of a nonwoven fabric. An absorbent body is attached on the outer covering sheet to absorb excrement from the wearer. Sheet members are bonded, (also called “end sheets” or “end holding sheets”) on the front and back, each end portion of the absorbent body being positioned and fixed between the sheet member and the outer covering sheet. The sheet member may be a laminated sheet of plastic film and nonwoven fabric, stretching of the sheet member is suppressed and it is possible to easily bring the absorbent body in close contact with the crotch region of the wearer when putting the disposable diaper on the wearer. The sheet member may also be formed of nonwoven fabric, a fiber orientation of nonwoven fabric on the sheet member then being orthogonal to the edges of end portions of the outer covering sheet in the longitudinal direction, to suppress longitudinal stretching of the sheet member.

A method of forming a composite sheet that is made of a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The method involves mechanically deforming a precursor nonwoven web to form a first web with deformations therein. The deformations form protrusions that extend outward from the first surface of the first web and openings in the other surface of the web. The method involves feeding the first nonwoven web with the deformations therein into a bonding nip where portions of the first region of the first web outside of the deformations are bonded to the second web to form a base-bonded composite web.

An absorbent article includes a surface sheet that is a non-woven fabric including a first fiber layer configured from cotton and thermoplastic resin fibers and a second fiber layer configured from hydrophobic thermoplastic resin fibers. The non-woven fabric includes: a first surface that is the surface on the side facing the skin and that is formed from the second fiber layer; and a second surface that is the surface on the side not facing the skin and that faces an absorbent body. The non-woven fabric is provided with a plurality of protrusions protruding toward the first surface and a plurality of recessed sections that are provided between adjacent protruding sections and that are recessed toward the second surface. The protrusions include a gap section facing the second surface of the non-woven fabric. 1. An absorbent article including a liquid-permeable top sheet situated on a side facing a skin of a wearer , a liquid-impermeable back sheet situated on a side not facing the skin of the wearer , and an absorbent body situated between both sheets ,wherein the top sheet is a nonwoven fabric comprising at least two fiber layers including a first fiber layer composed of cotton and thermoplastic resin fibers and a second fiber layer composed of hydrophobic thermoplastic resin fibers,the nonwoven fabric having a first surface which is a skin-facing side surface, formed by a second fiber layer, and a second surface which is a non-skin-facing side surface, facing the absorbent body, the nonwoven fabric being provided with a plurality of protrusions protruding toward the first surface and a plurality of recesses depressed toward the second surface, and formed between adjacent protrusions,each of the protrusions having an empty space faced by the second surface of the nonwoven fabric.2. The absorbent article according to claim 1 , wherein the back sheet has air permeability.3. The absorbent article according to claim 1 , wherein the first fiber layer includes a cotton ...

[PROBLEM] To prevent an overlapping portion formed by overlapping the side portions of an enveloping sheet for enveloping an absorber from opening, and to enable a fluid to smoothly diffuse in the absorber. [SOLUTION] An incontinence pad ( 1 ) includes a permeable front-side sheet ( 3 ), a back-side sheet ( 2 ), an absorber ( 4 ) enveloped by an enveloping sheet ( 5 ) and disposed between the permeable front-side sheet and the back-side sheet, and bilaterally-symmetric embossments ( 10 ) formed in a front surface of the permeable front-side sheet ( 3 ). An overlapped portion ( 9 ) is formed on a front side of the absorber ( 4 ) along a longitudinal direction by overlapping the side portions of the enveloping sheet ( 5 ). The longitudinal length of one of the bilaterally-symmetrical embossments ( 10 ) that overlaps the overlapped portion ( 9 ) is greater than or equal to 70% of the longitudinal length (LS) of the overlapped portion ( 9 ), and the lateral length of one of the bilaterally-symmetrical embossments is greater than or equal to 10% of the lateral length (WS) of the overlapped portion ( 9 ). An adhesive for bonding the side portions of the enveloping sheet ( 5 ) is not applied to a longitudinal area of the overlapped portion ( 9 ) where the embossment ( 10 ) is formed.
