Abstract
A strainer for use with materials such as paint and having a funnel shaped polypropylene body with a stainless steel wire screen bonded to the narrow opening thereof. The screen has a sufficiently small mesh to permit passage of normal paint particles but to prevent passage of dust and other undesirable particles. The mesh is made sufficiently large to permit flexure such as to prevent the accumulation of paint.
