Abstract
A fluid applicator for applying a fluid to a surface protrusion. In one embodiment, an anticorrosion substance is applied to a structural fastener.
Claims19
A method of coating a structural fastener with an anticorrosion fluid substance which comprises covering the fastener with a porous material and controllably flowing the anticorrosion substance to the porous material so as to uniformly coat the fastener with the substance.
A method for applying a fluid to a surface protrusion with a fluid applicator, said applicator comprising a hollow body having an elongated axis with opposing ends and an opening at each of the opposing ends, a porous material positioned inside said hollow body along the elongated axis, said material containing an aperture at one end and opening of the hollow body, said aperture having a predetermined depth and predetermined geometric shape so as to allow the porous material to cover a surface protrusion of a given height and a geometric shape such that fluid flowing from the porous material is controllably and uniformly applied to the protrusion.
A method for applying a fluid to a surface protrusion with a fluid applicator, said applicator comprising a hollow body having an elongated axis with opposing ends and an opening at each of the opposing ends, a porous material positioned inside the hollow body along the elongated axis, the porous material containing an aperture at one end and opening of the hollow body, said porous material aperture having a predetermined depth and diameter so as to match the height and the geometric shape of the surface protrusion and cover the surface protrusion such that fluid flowing from the porous material is controllably and uniformly applied to the protrusion.
A method for applying an anticorrosion fluid to a surface protrusion with a fluid applicator, said applicator comprising a hollow body having an elongated axis with opposing ends and an opening at each opposing end, a porous material positioned inside the hollow body along the elongated axis, said porous material comprising two separate sections, one section of the porous material containing an aperture at one opening of the hollow body, said aperture having a predetermined geometric shape and an aperture depth equal to or greater than the height of the protrusion to allow the porous material to cover a surface protrusion such that the anticorrosion fluid flowing from the porous material is controllably and uniformly applied to the protrusion.
