Film canister with independent sealing surfaces

摘要

A reusable container for a photographic film includes a body section having an open end, and a cap for covering the open end including an engagement portion for engaging the open end of the container body. According to the invention, the engagement portion of the cap includes a circumferential rib member for engaging a corresponding recess of the body for releasably securing the cap to the body, as well as a separately defined sealing surface having a radius which is larger than a corresponding sealing surface of the body in order to tightly seal and thereby prevent the significant passage of light, dust or moisture into the container when the cap is secured to the body of the container.
