Patent number: 6010253Abstract: The present invention is a film packet which includes a photosensitive film sheet having leading and trailing ends. A light-shielding envelope removably encloses the carrier sheet and the film sheet. The envelope has first and second exterior surfaces overlying the first and second outward-facing surfaces respectively and has first and second interior surfaces facing the first and second outward surfaces respectively. The envelope includes longitudinally extending leading and trailing end portions overlying the leading and trailing end sections respectively. The leading end portion is sealed closed, and the trailing end portion is closable by cooperative engagement with the light-locking element. The leading end portion includes first and second graspable zones. The first graspable zone overlies the tab so that, when grasped, the first zone is pressed against the tab and the second graspable zone does not overlie the tab so that, when grasped, the second zone is not pressed thereagainst.Type: GrantFiled: August 27, 1998Date of Patent: January 4, 2000Assignee: Eastman Kodak CompanyInventors: Vito A.
