Abstract

Abstract A lens-fitted photographic film unit has a film housing, which is preloaded with photographic film and provided with photograph-taking structure. A protuberant portion is formed in front of the film housing. A cardboard packaging covers the film housing. A four-sided portion of the packaging is curved to project outwardly by pressure molding, and fitted on the protuberant portion. In a preferred embodiment, a cassette is contained in the film housing with its axis vertical and is disposed near an end of the film housing, and contains the film after the film has been exposed. The protuberant portion and the four-sided portion are curved about the outside of the cassette, to be used as a grip. Two slits are formed in the packaging and along respective horizontal sides of the four-sided portion, in order partially to expose the protuberant portion. The film housing is black. On the packaging, the edges of the slits are black.
