Moldable self-adhering fastener cover and installation method
First Claim
1. In combination, an installation tool and a pliable flat disk for covering and sealing the head of a fastener protruding from a surface:
- said pliable flat disk being of laminated construction having a thin top layer of deformable material bonded to a relatively thicker intermediate layer of pliable adhesive sealant material and a removable bottom layer of release paper covering the exposed surface of said sealant material;
said installation tool having disk holding means at one end for releasably holding said flat disk thereon, said end having a recess slightly deeper than the height of the head of the fastener and said recess having an interior slightly larger than the outer periphery of the head of the fastener;
said disk holding means holding said flat disk on said end of said tool in a position covering said recess with said release paper layer facing outwardly from said end; and
said flat disk being installed on the head of the fastener by removing said release paper to expose said adhesive sealant material and placing said tool with said flat disk held on said end in a position generally centered on the fastener head and pressing said tool downwardly to deform said flat disk to encompass and conform substantially to the shape of the head of the fastener and cover a surface radially surrounding the fastener head and adhere to the fastener head and adhere the fastener head to the radially surrounding surface and provide an air-tight and liquid-tight seal between the fastener head and radially surrounding area and prevent relative movement therebetween.

Abstract
A pliable flat disk of laminated construction having a thin top layer of deformable material bonded to a relatively thicker intermediate layer of pliable adhesive sealant material and a removable bottom layer of release paper covering the exposed surface of the sealant material is deformed during installation to cover and seal the head of a fastener protruding from a surface. The disk is installed by a tool having an end adapted to hold the flat disk. The end of the tool has a recess slightly deeper than the height of the head of the fastener and an interior slightly larger than the outer periphery of the head of the fastener. The flat disk is releasably attached on the end of the tool and covers the recess. The release paper is removed to expose the adhesive sealant material and the tool with the flat disk held thereon is generally centered on the fastener head and pressed downwardly with a twisting motion to deform the flat disk such that it encompasses and conforms to the shape of the head of the fastener and covers a surface radially surrounding the fastener head and adheres to the fastener head and adheres the fastener head to the radially surrounding surface and provides an air-tight and liquid-tight seal between the fastener head and radially surrounding area and prevents relative movement therebetween. It will also cover and seal a washer if one is used with the fastener.

12. A method for covering and sealing the head of a fastener protruding from a surface utilizing an installation tool and a pliable flat disk, comprising the steps of;
-
providing a pliable flat disk of laminated construction having a thin top layer of deformable material bonded to a relatively thicker intermediate layer of pliable adhesive sealant material and a removable bottom layer of release paper covering the exposed surface of said sealant material; providing an installation tool having disk holding means at one end for releasably holding said flat disk thereon, said end having a recess slightly deeper than the height of the head of the fastener and said recess having an interior slightly larger than the outer periphery of the head of the fastener; placing said flat disk in said disk holding means on said end of said tool in a position to cover said recess with said release paper layer facing outwardly from said end; removing said release paper to expose said adhesive sealant material and placing said tool with said flat disk held on said end in a position generally centered on the fastener head; and pressing said tool downwardly to deform said flat disk to encompass and conform substantially to the shape of the head of the fastener and cover a surface radially surrounding the fastener head and adhere to the fastener head and adhere the fastener head to the radially surrounding surface and provide an air-tight and liquid-tight seal between the fastener head and radially surrounding area and prevent relative movement therebetween. - View Dependent Claims (13, 14, 15)
