Double-walled basket with permanent straining device

Abstract

The invention claimed is a double walled basket strainer with permanent straining device.

What I claim is: 
     
         1 . A sink strainer comprising:
 a flange clamp;   a strainer screen having a base portion and a strainer screen wall, which further extends into a strainer screen flange;   a strainer body which extends into a strainer body flange;   the strainer body further comprised of a tapered portion;   wherein the flange clamp receives the strainer screen flange and the strainer body flange.   
     
     
         2 . The sink strainer according to  claim 1 , wherein the flange clamp operably attaches the strainer screen flange and the strainer body flange with a “C” cross-section. 
     
     
         3 . The sink strainer according to  claim 1 , wherein the strainer screen wall is substantially parallel to the strainer body wall and defines a gap there-in-between. 
     
     
         4 . The sink strainer according to  claim 3 , wherein the distance of the gap is in the range of 0.25 to 1.0 inch, and preferably in the range of 0.65 to 0.85 inches. 
     
     
         5 . The sink strainer according to  claim 4 , wherein the distance of the gap is 0.76 inches. 
     
     
         6 . The sink strainer according to  claim 1 , wherein the diameter of the strainer screen is in the range of 2.0 to 3.2 inches. 
     
     
         7 . The sink strainer according to  claim 1  wherein the diameter of the strainer screen is in the range of 2.3 to 2.8 inches. 
     
     
         8 . The sink strainer according to  claim 1 , wherein the diameter of strainer body is in the range of 3.0 to 4.0 inches. 
     
     
         9 . The sink strainer according to  claim 7 , wherein the diameter of the strainer body is in the range of 3.0 to 3.5 inches. 
     
     
         10 . The sink strainer according to  claim 1 , wherein the strainer screen is a perforated, stainless-steel. 
     
     
         11 . A method for to manufacture a sink strainer where the sink strainer is comprised of:
 a flange clamp;   a strainer screen having extending into a base portion and an inner strainer screen wall, which further extends into an upper strainer screen flange; a strainer body which extends into a strainer body flange; the strainer body further comprised of having a tapered portion; connected to a threaded portion and an outer wall, which further extends into a lower flange. extending to an outer wall, which further extends into a tapered portion connected to a threaded portion   comprising the steps of:   the flange clamp permanently receiving the strainer screen flange and the strainer body flange;   operably securing the same with a “C” clamp cross section.   
     
     
         12 . The method according to  claim 11 , wherein the strainer screen wall is substantially parallel to the strainer body wall and defines a gap there-in-between. 
     
     
         13 . The method according to  claim 12 , wherein the distance of the gap is in the range of 0.25 to 1.0 inch, and preferably in the range of 0.65 to 0.85 inches.
