Sock tagging device and method

A sock tagging device to be used in multiplicity comprising firstly a penetrating component made of solid material which, because its form resembles that of a common thumbtack, will hereinafter be referred to as the tack, having a solid, cylindrical piercing post protruding perpendicularly from the center of a disc base which will henceforth be referred to as the tack disc, secondly a cap core made of solid material, having a cylindrical receiving void extending perpendicularly from the center of its circular base facet to a point just short of emerging from the cap core material, and thirdly a cap ring made of solid material through which said cap core can be partially inserted such that both core and ring, when mated in such manner, form a composite cap in the shape of a dome, having hemispherical appearance, and hereinafter referred to as the cap, said cylindrical receiving void of said cap core being of a diameter corresponding in such a way with the diameter of the aforementioned piercing post that when said piercing post is forced deeply into said receiving void sufficient friction is generated between the exterior cylindrical surface of the inserted post and the interior cylindrical surface of the cap core material to cause said tack and said cap core, bearing its accompanying cap ring, to remain coupled and resistant to ambient and prevailing forces that would otherwise tend to separate them, such that when the piercing post of the tack is pushed through the fabric of a sock and then forced deeply into the receiving void of the cap core, thereby sandwiching the sock fabric between the tack disc and the base facet of the cap core, the tack and cap remain securely affixed to the sock, and whereby the tack, cap core and cad ring each independently bear any one of a multiplicity of distinctive colors.
