Patent number: 6644501Abstract: A sheet package can prevent a sheet from causing damage upon dispensing the sheet through a dispensing opening without widening an opening width of the dispensing opening and providing extra gap within a package container. The sheet package includes a sheet stack, in which a plurality of folded sheets are stacked, received within a package container with a dispensing opening. Each individual sheet is folded into two-ply sheet along a first folding line, two sheets of the two-ply sheet are folded along a second folding line extending in parallel to the first folding line together for forming a folded sheet, a plurality of folded sheets are stacked in such a manner that a portion including the first folding line of a lower folded sheet is disposed within a valley folded portion of an upper folded sheet.Type: GrantFiled: December 5, 2001Date of Patent: November 11, 2003Assignee: Uni-Charm CorporationInventor: Yukiko Iida

Patent number: 6319593Abstract: A cleaning sheet including a base sheet and at least one surface layer of filaments placed on the base sheet is described. The filaments extend in one direction and each of the filaments extends over the whole length of the surface layer in the extension direction of the filaments. The base sheet and the surface layers are bonded to each other at a plurality of bonding lines intersecting the extension direction. The surface layer includes a plurality of filaments-holding regions, each of which includes at least one end of the bonding line other than the bonding lines forming the filaments-holding region. Accordingly, in the filaments-holding regions, differences-in-level for collecting dust are formed and gaps (pockets) for capturing the dust therein are exposed.Type: GrantFiled: March 18, 1999Date of Patent: November 20, 2001Assignee: Uni-Charm CorporationInventors: Yasuhiko Kenmochi, Yoshinori Tanaka, Yukiko Iida
