Abstract
A processing fluid receptacle of a photographic processing fluid applicator for use in a photographic film cassette capable of processing latent images on exposed film without requiring removal of the film from the cassette. The receptacle has an aperture which is initially releasably sealed by a web comprising two sections angularly disposed relative to each other with one section folded over the other. One section serves to seal the aperture, the arrangement being such that when a pulling force is exerted on the other section, the web is peeled off the receptacle in such a way that separation initially takes place along one margin of the aperture only.
