Abstract
A daylight reloadable lighttight plastic cassette for holding and dispensing a roll of light sensitive material is formed of a hollow open-ended tubular housing having lighttightly mating hingedly connected base and lid sections which pivot apart on the hinge to open the housing, A dispensing slot lighttightly sealed, e.g. by plush fabric, is present on the housing side opposite the hinge, preferably defined between suitably spaced longitudinal edges of the housing sections. The opposite housing ends are lighttightly closed by end caps, each molded in two mating sections, which are telescopingly fitted on end margins of the housing sections. The end cap sections can be carried by the respective housing sections to pivot therewith in clam-shell fashion. The housing sections can be latched in closed position, preferably with latches engaging the end cap sections. Alternatively, the end cap sections for each end cap can be hinged together with one section anchored on a housing section while the other cap section is flippable on the hinge laterally of the end cap to free the other housing section for opening the housing.
