Abstract
A plastics button assembly comprises an outer body component, an inner body component trapped substantially non-retrievably within a recess in the rear of the outer body component, and a cloth cover substantially covering the front of said outer body component, the edges of which are trapped securely between the engaging surfaces of said outer and inner body components. A shank extends from within the recess of the outer component and the inner component is engaged about and supported by the shank. The inner component is a specially shaped annular plastic washer having a flat inner face and a contoured outer face. An annulus of reduced thickness extends about a central aperture, and this annulus is surrounded by an annulus of maximum thickness which tapers towards the periphery of the washer. This allows the plastics button to be assembled in a conventional two piece die set as used for metal shell buttons.
