ABSTRACT:
A container assembly for a telephone repeater or the like including a circular flat base of metal and a dome-like cover of plastic. The cover includes an outwardly extending, flared flange for engagement against a chamfered outer edge portion of the base. The flange is secured to the base by a V-groove ring, one wall of which defines, in conjunction with the chamfer of the base, an outwardly flared annular chamber for receiving the flared flange. An O-ring is seated in a groove in the chamfer of the base in pressure engagement against the flared flange of the cover.
The arrangement maintains an air tight seal between the cover and the base over a wide range of temperatures despite a difference between the thermal expansion characteristics of the metallic base and the plastic cover.
