An applicator system particularly useful in a compact motion picture film-handling cassette and which includes a dispensing container having a reservoir chamber for retaining processing fluid with an orifice provided therethrough. A slider displaceably mounted for movement along the dispensing container includes a frame portion across which a strip of flexible material is mounted to overlay the container's orifice. An opening is provided through the strip of flexible material to be out of alignment with the orifice when the slider is in its initial position, to be aligned with the orifice when the slider is in a second position and to once again be out of alignment with the orifice when the slider is in a third position. A leaf spring carried by the slider continually urges a pressure plate towards the strip of flexible material. The filmstrip is progressively advanced across the orifice intermediate the strip of flexible material and the aforementioned pressure plate. When the slider is in its initial and third positions, guide tracks on the dispensing container position the pressure plate in spaced-apart relationship to the filmstrip. These guide tracks are configured such that, when the slider is in its second position, the pressure plate slideably engages the filmstrip against the flexible material. Cooperating portions of the slider and the dispensing container engage one another to preclude further movement of the slider once it has been displaced into its third position.
