Abstract
A one-time-use camera comprises a film cartridge and a filmstrip, a lighttight camera body having an interior chamber for the film cartridge and an exterior cover portion for light-tightly sealing the chamber that can be separated from another exterior (remaining) portion to open the chamber in order to remove the film cartridge, and matching respective indicia on the outside of the camera body and on the film cartridge and/or the filmstrip. The indicia on the outside of the camera body is positioned partially on the exterior cover portion and partially on the other exterior portion to be divided in order to be visually obliterated when the exterior cover portion is separated from the other exterior portion to open the chamber. Thus, the one-time camera cannot practically be reused without removing or covering the part of the indicia on the other exterior (remaining) portion of the camera body.
