Abstract

The present invention relates to a toilet cleaning device which comprises a handle, and a cleaning head, where the handle comprises an elongate shaft with opposite first and second ends and a longitudinal axis. The cleaning head comprises an upper surface, which connects to the second end of the handle, a lower surface opposite to the handle, and a lower rim which defines a plane, where the longitudinal axis of the elongate shaft forms an acute angle with the plane of the cleaning head, and wherein the lower surface comprises a cavity surrounded by a flange, on which flange the lower rim is defined.

Claims

1. A toilet cleaning device, comprising:

a handle; and

a cleaning head;

said handle comprising an elongate shaft, with opposite first and second ends, and a longitudinal axis;

said cleaning head comprising

an upper surface connecting to said second end of said handle,

a lower surface opposite to said handle,

a transition-portion forming a transition between said handle and the upper surface of said cleaning head; and

a flange extending outward from said transition portion;

said lower surface comprising an outer perimeter, said outer perimeter defining a plane,

said longitudinal axis of said elongate shaft, forming an acute angle with said plane,

wherein a cavity is formed in at least a part of said lower surface of said cleaning head within said outer perimeter.

2. The toilet cleaning device, according to claim 1, wherein said transition-portion forms a smooth, gradual transition between said handle and said upper surface of said cleaning head.

3. The toilet cleaning device according to claim 1, wherein one or more ribs are formed on said lower surface of said cavity.

4. The toilet cleaning device according to claim 3, wherein said cleaning head has a flat, elongate shape with a first longitudinal axis, said first longitudinal axis being parallel with both said plane defined by said perimeter, and said longitudinal axis of said shaft, and wherein said ribs intersect said-first longitudinal axis of said head.

5. The toilet cleaning device according to claim 3, wherein said one or more ribs are V shaped.

6. The toilet cleaning device, according to claim 2, wherein said cavity is formed in said lower surface opposite to said transition-portion and thereby opposite to said handle.

7. The toilet cleaning device according to claim 2, wherein a scrubbing knob is formed on an upper surface of said flange, said scrubbing knob extending from said upper surface in a direction perpendicular to said plane, and in a direction towards said handle.

8. The toilet cleaning device, according to claim 7, wherein the knob is formed in a position on said flange between said handle and said flange where said handle forms said acute angle with said plane of said cleaning head.

9. The toilet cleaning device, according to claim 1, wherein one or more slits are formed in an edge of said flange.

10. The toilet cleaning device, according to claim 1, wherein said handle is formed in a hard, rigid material.

11. The toilet cleaning device, according to claim 10, wherein said cleaning head is formed in a material which is softer and more resilient than said handle.

12. The toilet cleaning device, according to claim 1, wherein said handle comprises a head core portion forming an extension of said elongate shaft at said distal end thereof, said head core portion extending into said head to form a connection thereto.

13. The toilet cleaning device, according to claim 12, wherein said transition portion and said flange of said cleaning head are formed as one integrated piece by moulding onto said head core portion of said handle.

14. The toilet cleaning device, according to claim 1, wherein said acute angle between said longitudinal axis of said shaft of said handle and said plane is in the interval 30°

-60°

.

16. The method according to claim 15, wherein the toilet cleaning device further comprises any of the features defined in claim 14.

15. A method of cleaning a toilet bowl (100), said method comprising

providing a toilet cleaning device (1), said toilet cleaning device (1) comprising

a handle (10), and

a cleaning head (20)

said handle comprising an elongate shaft, with opposite first and second ends, and a longitudinal axis;

said cleaning head comprising

an upper surface connecting to said second end of said handle,

a lower surface opposite to said handle,

a transition-portion forming a transition between said handle and the upper surface of said cleaning head; and

a flange extending outward from said transition portion;

said lower surface comprising an outer perimeter, said outer perimeter defining a plane,

said longitudinal axis of said elongate shaft, forming an acute angle with said plane,

where a cavity is formed in at least a part of said lower surface of said cleaning head within said outer perimeter;

applying pressure to said handle in a direction towards said inner surface of said toilet bowl;

moving said cleaning head over said inner surface of said toilet bowl; and

entering a portion of said flange into a water outlet crevice of said toilet bowl.
