  • One or two part container drain strainer assembly that prevents clogging when draining liquids from containers
    Patent number: 7681740
    Abstract: A two part drain assembly for a container assembly with a drain for flowing fluid from the interior of the container assembly to exterior of the container assembly. A back plate comprising a first sliding engagement means parallel a second sliding engagement means connected by a back plate body, wherein a drain attachment hole is disposed on the back plate body and a bottom plate is disposed perpendicular to the first sliding engagement means and the second sliding engagement means. A front cover comprising a plurality of flow holes for slidably engaging simultaneously the first sliding engagement means and the second sliding engagement means, wherein the front cover forms an enclosed hollow chamber when slidably engaged with the back plate thereby permitting fluid to flow from the interior of the container assembly into the hollow chamber while excluding particles from entering the enclosed hollow chamber.
