Abstract: The present invention is directed toward a device used to strain paint and other liquid products. The device includes a piece of mesh material fixed at its perimeter in a ring. The material and cross-sectional shape of the ring is designed to permit compression of the shape, allowing the ring to conform to, and bias against, the lid well of a container, such as that of a paint can, by press-fit. Compression of the cross-sectional shape of the ring may be facilitated by the placement of an elastomeric spline in a channel of the ring. Additionally, a tab may be fixed to the ring of the device to provide a means for grasping the device and to disengage the device from the lid well of the container.
