Abstract
A closure arrangement comprises an aperture-defining frame, a closure panel member which fits removeably into the frame, and a radio-frequency seal between the frame and an edge of the panel member. The seal is divided into two complementary parts attached respectively to the panel member and to the frame, the parts extending over different sections of the periphery of the aperture and cooperating to cover the entire periphery only when the panel member is closed. To improve the seal, a sharp ridge is formed in the edge of the panel member to enhance the contact pressure exerted on the seal locally on a line extending along the seal.
