## Abstract

The dustpan cover is a cleaning device. The dustpan cover is configured for use in collecting debris from a horizontal surface. The dustpan cover comprises a dustpan, a lid, and a fastener. The fastener attaches the lid to the dustpan. The lid is a barrier that controls access to the dustpan. The dustpan is a traditional cleaning tool used to collect debris from a horizontal surface such as a floor. The lid rotates relative to the dustpan such that the dustpan opens and closes for the collection and disposal of debris.

## Claims

### Claim 1

A domestic cleaning apparatus comprising:
a dustpan, a lid, and a fastener;
wherein the fastener attaches the lid to the dustpan;
wherein the lid is a barrier that controls access to the dustpan;
wherein the domestic cleaning apparatus is configured to collect debris;
wherein the dustpan is configured to collect debris;
wherein the lid rotates relative to the dustpan such that the dustpan opens and closes for the collection and disposal of debris;
wherein the dustpan is a containment structure;
wherein the dustpan is a wedge-shaped structure;
wherein the lid controls access to a storage space within the dustpan;
wherein the lid rotates relative to the dustpan;
wherein the fastener is a spring-loaded device;
wherein the fastener attaches the lid to the dustpan such that the lid rotates towards and away from a superior face of a collection bin;
wherein the fastener seals the lid against the superior face of the collection bin;
wherein the dustpan comprises a collection bin and a handle;
wherein the handle attaches to the collection bin;
wherein the collection bin contains the debris;
wherein the collection bin is a hollow containment structure;
wherein the collection bin is a wedge-shaped structure;
wherein the collection bin comprises a first vertical face, a second vertical face, a third vertical face, an inferior face, a superior face, and a wedge cant;
wherein the superior face is an open face;
wherein the first vertical face, the second vertical face, the third vertical face, the inferior face, the superior face combine to form the wedge shape of the containment bin;
wherein the wedge cant is the angle between the inferior face and the superior face;
wherein the first vertical face is a triangularly shaped plate;
wherein the second vertical face is a triangularly shaped plate;
wherein the third vertical face is a rectangular plate;
wherein the inferior face is a rectangular plate;
wherein the superior face is a rectangular plate;
wherein the first vertical face projects perpendicularly away from the inferior face;
wherein the second vertical face projects perpendicularly away from the inferior face;
wherein the third vertical face projects perpendicularly away from the inferior face;
wherein the first vertical face shares its perimeter with the third vertical face, the inferior face, and the superior face;
wherein the second vertical face shares its perimeter with the third vertical face, the inferior face, and the superior face;
wherein the third vertical face shares its perimeter with the first vertical face, the inferior face, and the superior face;
wherein the superior face shares its perimeter with the first vertical face, the second vertical face, the third vertical face, and the inferior face;
wherein the second vertical face is distal from the first vertical face;
wherein the third vertical face is distal from the line formed by the intersection of the inferior face and the superior face;
wherein the inferior face and the superior face are not parallel planar surfaces;
wherein a wedge angle is the acute angle formed between the inferior face and the superior face;
wherein the handle is a shaft;
wherein the handle is used as a grip;
wherein the handle attaches to the third vertical face of the collection bin;
wherein the handle attaches to the third vertical face such that the handle projects away from the intersection of the inferior face and the superior face;
wherein the handle attaches to the third vertical face such that the handle forms a grip cant with the inferior face;
wherein the span of the arc of the grip cant between the handle and the inferior face equals the span of the arc of the wedge cant;
wherein the lid encloses a containment space of the dustpan;
wherein the lid comprises a barrier plate and a lever plate;
wherein the barrier plate attaches to the fastener;
wherein the lever plate attaches to the fastener;
wherein the barrier plate is a plate structure;
wherein the perimeter of the barrier plate is geometrically similar to the perimeter of the superior face of the collection bin;
wherein the span of the perimeter of the barrier plate is greater than the span of the perimeter of the superior face.

### Claim 2 (depends on 1)

The domestic cleaning apparatus according to claim 1 wherein the fastener attaches the barrier plate to the handle of the dustpan.

### Claim 3 (depends on 2)

The domestic cleaning apparatus according to claim 2
wherein the fastener comprises a hinge and a spring;
wherein the spring is incorporated into the hinge;
wherein the barrier plate and the lever plate attach to the hinge.

### Claim 4 (depends on 3)

The domestic cleaning apparatus according to claim 3
wherein the hinge rotates the barrier plate relative to the collection bin;
wherein the lever plate is a leverage device;
wherein the lever plate attaches to the hinge such that a force applied to the lever plate will rotate the barrier plate.

### Claim 5 (depends on 4)

The domestic cleaning apparatus according to claim 4
wherein the spring torsion spring;
wherein a torque is applied to the spring such that the spring attempts to return the lid and the dustpan to the relaxed shape;
wherein when the spring is in its relaxed shape the lid seals the superior face of the collection bin.
