Patent number: 9918882Abstract: A tampon applicator includes an outer tube for containing at least a part of an absorber therein, a first inner tube and a second inner tube. The second inner tube is telescopically received within the first inner tube. The first inner tube and the second inner tube are connectable to each other during use to push out the absorber from the outer tube. At least a part of the first inner tube and at least a part of the second inner tube overlap with each other in an overlap region outside the outer tube. A color difference between the outer tube and the overlap region is higher than a color difference between the overlap region and the second inner tube.Type: GrantFiled: September 12, 2013Date of Patent: March 20, 2018Assignee: UNICHARM CORPORATIONInventors: Yukihiro Ito, Kenta Taniguchi, Kouichi Yamaki, Azusa Matsushima, Akie Kinoshita

Patent number: 9439817Abstract: A water-disintegrable absorbent article adapted to be easily peeled off the wearer's undergarment after use. A pantiliner has a topsheet lying on a body side of the wearer, a backsheet and a liquid-absorbent body interposed between the top- and backsheets. The backsheet may be formed of a water-disintegrable fibrous nonwoven fabric of which the component fibers have an orientation extending in a longitudinal direction. On a non-body side, first adhesive regions adapted to be attached to the wearer's undergarment and second adhesive regions allocated on both outer sides in a transverse direction of the first adhesive regions so as to be spaced in the transverse direction from the first adhesive regions. The first adhesive regions include front first adhesive regions, rear first adhesive regions and central first adhesive regions allocated between the front and rear first adhesive regions spaced apart from each other in the longitudinal direction.Type: GrantFiled: June 7, 2012Date of Patent: September 13, 2016Assignee: Unicharm CorporationInventors: Kiyoko Nishimura, Toshiyuki Tanio, Azusa Matsushima

Patent number: 9295589Abstract: A water disintegratable leak-proof sheet for an absorbent article that has an excellent leak-proof property during wear and excellent water disintegrating property after disposal. The water disintegratable leak-proof sheet of the present disclosure has the following construction. A water disintegratable leak-proof sheet for an absorbent article comprising a water disintegratable base material layer and a water-insoluble and biodegradable resin layer on the water disintegratable base material layer, wherein the tearing strength in the planar direction of the water disintegratable leak-proof sheet is no greater than 0.15 N/40 mm in both a first direction and a second direction perpendicular to the first direction.Type: GrantFiled: February 27, 2012Date of Patent: March 29, 2016Assignee: Unicharm CorporationInventors: Takayoshi Konishi, Koichi Yamaki, Azusa Matsushima

Patent number: 9119746Abstract: An absorbent article having water disintegratability that includes a water disintegratable top sheet, a water disintegratable back sheet, a pressure-sensitive adhesive section for attaching the absorbent article to clothing, disposed on the surface of the back sheet opposite the top sheet, and a release sheet for protection of a contact surface of the pressure-sensitive adhesive section which contacts with clothing. One or more protrusions and one or more depressions are formed on the contact surface of the pressure-sensitive adhesive section.Type: GrantFiled: September 28, 2011Date of Patent: September 1, 2015Assignee: Unicharm CorporationInventors: Azusa Matsushima, Kouichi Yamaki

Publication number: 20120292224Abstract: A package includes a packaging bag unit configured to package an absorbent article and a skirt unit provided on a surface of the packaging bag unit. The skirt unit extends along a side surface and encloses a bottom surface. The packaging bag unit packages the absorbent article such that an absorbing surface of the absorbent article is upright with respect to the bottom surface. Thus, the absorbing surface of the absorbent article is not in contact with the bottom surface, and therefore, it is possible to prevent the absorbing surface of the absorbent article from absorbing water even when the water is generated as a result of condensation inside the bottom surface of the packaging bag unit.Type: ApplicationFiled: November 26, 2010Publication date: November 22, 2012Applicant: UNICHARM CORPORATIONInventors: Azusa Matsushima, Koichi Yamaki
