Patent #: 7,211,071
Inventor(s): Yoshitaka Mishima and Tomoharu Hino
Company: Uni-Charm Corporation
A diaper package composed of a plurality of disposable diapers has been patented. Each diaper comprises a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core with a stiffness higher than these sheets and interposed between the two top- and backsheets. A flexible packing bag is adapted to pack the plurality of diapers. Each of the diapers has first and second waist regions and a crotch region along which the first and second waist regions are contiguous to each other and a waist-surrounding end portion opposite the crotch region so as to define upper end portions of the first and second waist regions, respectively. The packing bag defines top and bottom walls spaced from each other in a vertical direction. First and second walls are opposed to each other and extend between the top and bottom walls. A pair of side walls extends between the top and bottom walls so that a plurality of the diapers each folded back along the crotch region are compactly packed within a space surrounded by these walls. The diaper package further comprises a plurality of the diapers being arranged with their waist regions placed against one another to be arranged between the side walls to form a row extending between the side walls so that the respective crotch regions’ bottoms are aligned one with another between the side walls. They face the second wall and the waist-surrounding end portions of the respective diapers and are aligned one with another between the side walls, which face the first wall. A radius of curvature of a corner at which the first wall and the side walls cross each other is longer than a radius of curvature of a corner at which the second wall and the side walls cross each other so that a range in which the package can be visually recognized head-on from the side of the first wall is larger than a range in which the package can be visually recognized head-on from the side of the second wall.
