Abstract: A paint container adapter for facilitating painting is provided. The paint container adapter includes: a hollow cylindrical adapter body substantially open at both ends, the body having a continuous sidewall; the outer portion of the sidewall having one or more clips having an open end capable of aligning with an open end of the adapter body, a horizontally aligned ridge on the inner wall of the clip to reduce slippage, wherein the open end of the adapter body is capable of being inserted into an open cylindrical paint container to a sufficient depth so that the one or more clips engage an outer paint container flange, the inner horizontally aligned ridge of clip beneath the outer flange of the paint container, securing the paint container adapter to the paint container, and the outer wall of adapter body thereby compressed against an inner rim of the paint container reducing leakage occurring between the adapter and paint can seam.
