Patent number: 11337866Abstract: A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member (100) including synthetic fibers (10b). The method involves: a transporting step of transporting a plurality of sheet fragments (10bh) including synthetic fibers (10b) to an accumulating depression (41) by using a duct 3; an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) transported in the transporting step, and forming an accumulation (100a?) which is a constituent member of the absorbent member (100); and a pressing step of pressing the accumulation (100a?) over its entirety in the thickness direction.Type: GrantFiled: October 3, 2017Date of Patent: May 24, 2022Assignee: KAO CORPORATIONInventors: Tomoyuki Motegi, Yuki Kato, Ryuji Matsunaga, Takuaki Harada, Hiroyuki Iwasa

Patent number: 11207218Abstract: An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member (100) for an absorbent article and including synthetic fibers (10b) and hydrophilic fibers (10a). The method involves: a transporting step of transporting the hydrophilic fibers (10a) and a plurality of sheet fragments (10bh) to an accumulating depression (41) by using a duct (3); an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) and the hydrophilic fibers (10a), and obtaining an accumulation (100a) which is a constituent member of the absorbent member (100); and a depression forming step of forming a depression (100e) in the accumulation (100a) by applying pressure to a portion thereof.Type: GrantFiled: November 28, 2017Date of Patent: December 28, 2021Assignee: KAO CORPORATIONInventors: Yuki Kato, Ryuji Matsunaga, Takuaki Harada, Tomoyuki Motegi, Hiroyuki Iwasa

Publication number: 20200383849Abstract: Disclosed is an individual package (100) of a napkin (101) having a longitudinal direction (x1) corresponding to the wearer's front-rear direction and a lateral direction (y1) orthogonal to the longitudinal direction, the napkin (101) including a topsheet (102), a backsheet (103), and an absorbent core (110) arranged between the two sheets (102, 103), the napkin being packaged in a folded-up state. The napkin (101) is folded up in the longitudinal direction (x1) of the napkin (101), with the topsheet (102) on the inside, along a first folded/bent portion (IP1) and a second folded/bent portion (IP2) that extend in the lateral direction (y1) of the napkin (101). The absorbent core (110) includes a plurality of sheet fragments (10bh) including synthetic fibers (10b), and the sheet fragments (10bh) are provided at least on the topsheet (102) side in a thickness direction of the absorbent core (110).Type: ApplicationFiled: November 27, 2018Publication date: December 10, 2020Applicant: KAO CORPORATIONInventors: Ryuji MATSUNAGA, Takuaki HARADA, Tomoyuki MOTEGI, Yuki KATO, Hiroyuki IWASA

Patent number: 8793831Abstract: A lower face of a base body (15) includes a wave-like corrugated surface portion (19) of which cross-section in a direction perpendicular to a predetermined direction along which cleaning is performed with a cleaning device body (11) in a planar view is wave-shaped as having a ridge portion (17) and a valley portion (18) arranged alternately and continuously. The valley portion (18) of the wave-like corrugated surface portion (19) includes an oblique valley portion (18a) of which end part is opened to a side portion of the base body (15) facing to the predetermined direction as being extended obliquely against the predetermined direction to obliquely guide objects such as dust to be stuck to a cleaning sheet (13) in accordance with wiping of the surface to be cleaned.Type: GrantFiled: February 10, 2011Date of Patent: August 5, 2014Assignee: Kao CorporationInventors: Makoto Katou, Susumu Fujinami, Kimie Sannomiya, Yukio Noda, Tomohisa Hirata, Yutaka Hamano, Takuaki Harada

Patent number: 8784972Abstract: Disclosed is a composite sheet 1 composed of a substantially flat lower fibrous sheet 3 and an upper fibrous sheet 2 bonded to the lower fibrous sheet 3. The upper fibrous sheet 2 is three-dimensionally textured with a number of projections 5 and a number of depression 6 each of which is located between every adjacent two of the projections 5. The projections 5 and the depressions 6 alternate in both a first direction of the composite sheet 1 and a second direction perpendicular to the first direction. Each projection 5 has a pair of opposing first walls 51 parallel to the first direction and a pair of opposing second walls 52 parallel to the second direction. The basis weight of the first walls 51 is different from that of the second walls 52.Type: GrantFiled: October 30, 2008Date of Patent: July 22, 2014Assignee: Kao CorporationInventors: Kenichi Sato, Kenji Ando, Takuaki Harada, Yasuhiro Nakano
