Abstract
A button assembly includes a hollow button body having a garment-engaging base portion through which a shank of an eyelet is inserted into the botton body for being staked on the base portion to join the button body with the eyelet. The base portion includes a plurality of retaining ribs projecting into the interior of the button body for retaining thereon an annular curled edge of the shank when the eyelet is axially compressed. The ribs stiffen the base portion and increases the effective thickness of the base portion with the result that the shank can be joined with the button body by a relatively small rivetting force because the end portion of the shank to be deformed becomes short. With the interiorly projecting ribs, the base portion has a planar outer surface engageable flatwise against a garment fabric so that the button assembly can be attached neatly onto the garment fabric without any damage or wrinkles on the garment fabric around the button assembly.
