A two piece, resilient plastic assembly for decoratively covering the head of an installed fastener such as a screw or the like. The assembly comprises a resilient base member adapted to be held by the fastener or screw upon a planar portion of a workpiece. A resilient anchor member includes a planar, flange like base of generally circular cross section having a central orifice defined therein through which a screw or fastener passes, and an integral peripheral rim having an external surface upon which a plurality of radially spaced apart petals are integrally formed. A cup-like, resilient plastic cover plate adapted to be snap-fitted upon the anchor includes a generally convex top portion and a peripheral downwardly projecting rim. The cover plate rim includes a snap fit groove into which the anchor petals are received. This snap fit groove is separated from a lower expansion groove by an apex, and when the cover plate is pushed upon the anchor, the cap rim is expanded and the petals are slightly compressed by the compression groove. The anchor semipermanently secures the cover plate when the petals subsequently occupy the the snap fit groove, the geometry of which conforms generally to the profile of the petals.

A two piece, resilient plastic head cover assembly for decoratively covering the head of a conventional screw, bolt, or the like installed in or through a workpiece, at least a portion of said workpiece being substantially planar, said assembly comprising: an anchor member adapted to be secured in operative position by said screw, bolt or the like upon said planar portion of said workpiece, said anchor member comprising: a planar flange-like base of generally circular cross section having a central orifice defined therein for admitting said screw or the like therethrough, said base having an outer peripheral edge; a bottom comprising a flat underside of said base; an integral peripheral rim rising upwardly from the outer peripheral edge of said base, said rim coaxially surrounding said central orifice, said rim having a top and an external circumferential periphery; a plurality of radially spaced apart petals integrally formed upon said rim, said petals being generally in the form of an inverted conic section intersecting the periphery of said rim, and each of said petals having an outermost inclined edge; and, each of said petals comprising a horizontal top coplanar and contiguous with the top portion of said anchor member base rim and oriented substantially parallel with the planar surface of said workpiece when said assembly is installed upon said workpiece; and, a cup-like, resilient plastic cover plate adapted to be yieldably snap fitted to said anchor member to decoratively cover a head of said screw, fastener or the like, said cover plate comprising: a generally convex top portion; a peripheral downwardly projecting rim integral with said top portion, the last mentioned rim having an internal snap-fit groove defined therewithin for receiving said petals, said snap fit groove having a notch-like cross section conformed generally to frictionally contact the outermost inclined edges of each of said petals whereby to secure said cover plate to said base; and, an expansion groove defined interiorly of said cover plate rim in spaced-apart, generally parallel relation with respect to said snap fit groove and separated therefrom by an apex, said expansion groove adapted to expand said cover plate rim and initially slightly compress said petals when said cover plate is forcibly fitted to said anchor member.
