Patent application title: Chokeless Sink Strainer

Inventors:  Yeong Cherng Ho (Singapore, SG)
IPC8 Class: AE03C1264FI
USPC Class: 4292
Class name: Strainer

Abstract:

The invention resolves the choking problem of the existing sink strainers. The new design has a water outlet and a residues settlement area. See FIG. 7 for the concept design. The water outlet is designed at above the surface of the sink and the settlement area is at below the surface. The residues will eventually settle down in the settlement area when the water flows through the strainer. The water outlet will not be covered by the residues as it is above the surface. Having these two features in one will prevent the sinks from choking.

Claims:

1. The invention combines two features in the design to achieve the chokeless (Anti-Choke) solution. The features are as follow.A. Feature 1:The first feature is the filter (i.e. the area with holes) portion above the surface of the sink that prevents any settlement of residues and leave behind an outlet for the water to escape. See FIG. 5.B. Feature 2:The second feature is the filter (i.e. the area with holes) portion below the surface of the sink that allows settlement of the residues so that the residues will not block up the first feature. See FIG. 6As long as a strainer design consists of the above mentioned two features in one, regardless of the forms and shapes that will be the claim. See FIGS. 8, 9 and 10 for the sample designs in another forms and shapes

Description:

BACKGROUND OF THE INVENTION

[0001]1. Currently, the sink strainers in the market are designed lower than the surface of the sink. See FIG. 1.

[0002]2. This design has a problem. It causes the sink to choke when the residues eventually settle down and cover the strainer. See FIG. 2.

[0003]3. In the new design, the strainer is above the surface of the sink See FIG. 3.

[0004]4. The part that is above surface of the sink will not be covered by the residues and leave behind an outlet for the water to escape and eventually prevent choking the sink. See FIG. 4.
