Abstract

A sink including a body defining a vessel volume having an interior surface, wherein the body includes a bowl, where the bowl includes a base wall and at least one side wall extending from the base wall, where the bowl at least partially defines the interior surface, and a cup, where the cup includes a strainer plate defining one or more apertures therein and at least one side wall, where the cup at least partially defines the interior surface, where the body is formed from a single continuous piece of sheet material, and where the minimum thickness of the material forming the cup is no less than 50% of the maximum thickness of the material forming the bowl.

First claim

What is claimed is:

1. A sink comprising:
a body defining a vessel volume having an interior surface, the body including:
a bowl formed from sheet material, where the bowl includes a base wall and at least one side wall extending from the base wall, wherein the bowl includes a cylindrical first locating wall, and wherein the bowl at least partially defines the interior surface, and
a cup, where the cup includes a strainer plate defining one or more apertures therein, wherein the cup includes a cylindrical second locating wall, wherein the cup at least partially defines the interior surface, and wherein the cup is mechanically coupled to the bowl by a press-fit connection where the first locating wall directly contacts the second locating wall, and where the interference between the first locating wall and the second locating wall forms a water-tight connection therebetween without the use of a gasket.

2. The sink of claim 1 , wherein the cup defines a cup axis, wherein the cup axis is normal to the base wall, and wherein at least a portion of the bowl axially overlaps at least a portion of the cup.

3. The sink of claim 1 , wherein the strainer plate is offset from the base wall.

4. The sink of claim 1 , wherein an adhesive is used with the press-fit to secure the first piece of sheet material relative to the second piece of sheet material.

5. The sink of claim 1 , wherein the cup is configured to be directly coupled to a tail pipe.

6. The sink of claim 1 , wherein the press-fit connection does not include a crimp.

7. A sink comprising:
a vessel volume having an interior surface;
a bowl, where the bowl includes a base wall and at least one side wall extending from the base wall, wherein the bowl at least partially defines the interior surface;
a cup, where the cup includes a strainer plate defining one or more apertures and at least one side wall, wherein the cup at least partially defines the interior surface;
a first piece of sheet material forming the base wall of the bowl, and the at least one side wall of the bowl; and
a second piece of sheet material forming the strainer plate, and wherein the second piece of sheet material is mechanically coupled to the first piece of sheet material by a press-fit connection, where an adhesive is used with the press-fit to secure the first piece of sheet material relative to the second piece of sheet material, and where the interference fit between the first piece of sheet material and the second piece of sheet material forms a water-tight connection therebetween.

8. The sink of claim 7 , wherein the first piece of sheet material includes a first locating surface, wherein the second piece of sheet material includes a second locating surface, and wherein the first locating surface cooperates with the second locating surface to radially position the second piece of sheet material relative to the first piece of sheet material.

9. The sink of claim 8 , wherein the first locating surface defines a first diameter, wherein the second locating surface defines a second diameter, and wherein the first diameter substantially corresponds with the second diameter.

10. The sink of claim 9 , wherein at least a portion of the first locating surface axially overlaps with the second locating surface.

11. The sink of claim 8 , wherein the cup defines a cup axis, and wherein the first locating surface is parallel to the cup axis.

12. The sink of claim 7 , wherein one of the first piece of sheet material and the second piece of sheet material includes a pin, wherein the other of the first piece of sheet material and the second piece of sheet material defines a tortuous path, and wherein the pin is configured to travel along the tortuous path to couple the first piece of sheet material to the second piece of sheet material.

13. The sink of claim 7 , wherein the first piece of sheet material further includes a locating wall and wherein the second piece of sheet material is press-fit onto the locating wall.

14. The sink of claim 13 , wherein the cup defines a cup axis, and wherein the locating wall is parallel the cup axis.

15. The sink of claim 13 , wherein the cup includes at least one side wall extending from the strainer plate.

16. The sink of claim 15 , wherein the at least one side wall is perpendicular to the strainer plate.

17. The sink of claim 13 , wherein the locating wall is annular in shape.

18. A sink comprising:
a vessel volume having an interior surface;
a bowl, where the bowl includes a base wall and at least one side wall extending from the base wall, wherein the bowl at least partially defines the interior surface;
a cup, where the cup includes a strainer plate defining one or more apertures, wherein the cup at least partially defines the interior surface, and wherein the cup defines an axis;
a first piece of sheet material at least partially forming the bowl, wherein the first piece of material forms a locating wall that is parallel to the axis and cylindrical in shape; and
a second piece of sheet material at least partially forming the cup, and wherein the second piece of sheet material is mechanically coupled to the first piece of sheet material such that the locating wall of the first piece of sheet material directly contacts the second piece of sheet material to form a press-fit connection, and wherein the interference between the locating wall of the first piece of sheet material and the second piece of sheet material produces a water-tight connection therebetween.

19. The sink of claim 18 , wherein at least a portion of the first piece of sheet material and the second piece of sheet material axially overlap.

20. The sink of claim 18 , wherein the strainer plate is axially offset from the base wall of the bowl.

21. The sink of claim 18 , wherein the second piece of sheet material includes a second locating surface, and wherein the locating surface of the first piece of sheet material axially overlaps the second locating surface.

22. The sink of claim 21 , wherein the locating surface of the first piece of sheet material cooperates with the second locating surface to radially position the second piece of sheet material relative to the first piece of sheet material.

23. The sink of claim 18 , wherein the axis is normal to the base wall.

24. The sink of claim 18 , wherein an adhesive is used with the press-fit to secure the first piece of sheet material relative to the second piece of sheet material.
