The grease filter is made with components that are secured together about the periphery of the filter by a seam with smooth surfaces. In one embodiment, the filter is constructed of three components, namely, a pair of plates and a rectagular or square frame. The peripheral edges of the plates and frame are interfolded on each other to form a rolled seam. The resulting structure is rigid and does not twist.

The self-closing hinge assembly has a pair of cam members which are biased against each other by a pair of coil springs. The outer coil spring serves to bias the cam members together under a first restoring force and is effective during an initial opening of a door, for example to a 90.degree. position. The second inner spring becomes compressed only after the outer coil spring has been compressed. Compression of the second coil spring occurs as a door is opened beyond the 90.degree. position. The door may be held in one of two dwell positions corresponding to the cam surfaces on the movable cam member.
