Abstract
The present invention relates to a cartridge for packaging a roll film. The cartridge has a film outlet that is composed of upper and lower lips, each lip has a light-shielding ribbon attached to the inside thereof. Both extended side edge portions of the ribbon attached to the lower lip are slightly bent downwardly. Both extended side portions of the ribbon attached to the upper lip are also bent downwardly at a slightly larger angle than that of the lower lip. Consequently both side edge portions of both upper and lower lips overlap in a more complete manner or are more positively joined together.
