Abstract
A lens-fitted photographic film package includes a light-tight film case with a taking lens fitted thereto, an empty film container enclosed in the light-tight film case, and a rolled film with its one end retained in the empty film container enclosed in the light-tight film case. The light-tight film case consists of two sections one of which is formed with members for preventing the light-tight film case from being deformed by an external force. These members can be spaced horizontal parallel ribs cast into the plastic of the one film case section. Or those members can be a tongue on one section insertable in a bayonet slot in the other section.
