A strainer assembly for straining a liquid such as paint to be poured into the interior of an open top container includes a tubular strainer support having a continuous imperforate side wall structure with an open top, an open bottom, and an annular exterior flange for removably resting on the open top of the container for holding the strainer support in an upright position above the container. A filtering medium secured to the open top of the strainer support includes, in one ebmodiment, a thin, flexible tubular imperforate plastic sheet having an open top which is taped to the upper exterior portion of the strainer support. The flexible plastic sheet extends downwardly for most of the distance into the interior of the strainer support. A flexible mesh filtering cloth secured to the bottom of the tubular plastic sheet extends across a major portion of the projected area of the strainer support interior adjacent the top of the container. Paint is poured into the interior of the strainer support and through the mesh filtering cloth at the bottom to filter the paint before it passes into the interior of the container. In one embodiment, the strainer support is of stackable configuration and includes upper and lower annular exterior mounting flanges and a horizontally disposed, abrupt, annular step inside the support near its top for resting on top of the annular upper flange of a similar strainer support stacked below it.
