Patent number: 6619478Abstract: A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its each end a light-shielding flange disc has at its leading end a light-shielding leader sheet. The leader sheet is composed of a longitudinal light-shielding base sheet and two heat-shrinkable light-shielding strips, in which each of the light-shielding strips is tearable predominantly in its longitudinal direction and is fixed onto a surface of each side of the light-shielding base sheet under the condition that the light-shielding strip is aligned in parallel with the side of the longitudinal base sheet to project its portion from the side of the base sheet.Type: GrantFiled: December 26, 2000Date of Patent: September 16, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Masafumi Fukugawa, Akihisa Inoue, Norihiro Kadota, Koichi Nakatogawa

Patent number: 6375008Abstract: A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its each end a light-shielding flange disc has at its leading end a heat-shrinkable light-shielding leader sheet having a thickness of 30 to 200 &mgr;m which shows a heat shrinkage ratio at 50° C. of lower than 1% both in the longitudinal and width directions and a heat shrinkage ratio at 100° C. in the range of 5% to 30% in the longitudinal direction and a heat shrinkage ratio at 100° C. of less than the heat shrinkage ratio in the longitudinal direction by 1% or more in the width direction. The leader sheet has a length larger than the length of the outermost convolution of the roll and a width larger than the distance between the outer face of one flange disc and the outer face of another flange disc, and each side portion of the leader sheet is light-tightly attached by heat shrinkage to the outer face of the flange disc at least at a portion adjacent to the periphery of the flange disc.Type: GrantFiled: December 26, 2000Date of Patent: April 23, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Bungo Shigeta, Hirofumi Abe, Yasuhiko Kitamura, Yoshio Hara, Masafumi Fukugawa, Akihisa Inoue, Norihiro Kadota, Koichi Nakatogawa
