  • Cassette
    Patent number: 4013890
    Abstract: A cassette having a rectangular body made from plastic material including a marginal frame bounding a pair of film compartments separated by a radiation barrier and opening outwardly through opposite faces thereof. A pair of covers also made from plastic material and hingedly connected to opposite ends of the frame provide closures for the two film compartments. Each cover has a peripheral bead which is received within an associated groove in the frame when the cover is in a closed position. A U-shaped strip of magnetic material is sealed within each bead and cooperates with an associated U-shaped strip of magnetized material sealed within the body to releasably retain the cover in its closed position. The bead and groove further cooperate to comprise a light barrier for an associated film compartment.
