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 part of said lower surface of said cleaning head within said outer perimeter; and

wherein one nor more ribs are formed on said lower surface of said cavity.

2. The toilet cleaning device according to claim 1, 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.

3. The toilet cleaning device according to claim 1, wherein said one or more ribs are V shaped.

4. 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 part of said lower surface of said cleaning head within said outer perimeter; and

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.

5. The toilet cleaning device, according to claim 4, 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.

6. 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 part of said lower surface of said cleaning head within said outer perimeter; and

wherein one or more slits are formed in an edge of said flange.
