Abstract

A biodegradable toilet brush includes a biodegradable handle. The biodegradable toilet brush includes a brush head made of multiple layers of biodegradable fabric disks attached to and radiating outwardly from their attachment to the handle. Each of the fabric disks has a central slot dimensioned to receive the handle therethrough. The biodegradable toilet brush includes brush head retention pins that extend through spaced holes in the handle near a top of the handle and hold the fabric disks in place on the handle.

Claims (47)

1 . A biodegradable toilet brush comprising:

a biodegradable handle including two spaced pins extending laterally through the handle; and

a brush head made of multiple layers of biodegradable fabric disks attached to and radiating outwardly from their attachment to the handle, wherein:

each of the fabric disks has a central opening dimensioned to receive the handle therethrough, and

the two spaced pins are positioned to sandwich the fabric disks between the two spaced pins and hold the fabric disks in place with respect to the handle while allowing the fabric disks to spread and extend outwardly into a ball shape.

2 . The biodegradable toilet brush of claim 1 wherein the fabric disks are made of biodegradable cellulose fibers.

3 . The biodegradable toilet brush of claim 2 wherein the biodegradable cellulose fibers are formed from recycled wood pulp.

4 . The biodegradable toilet brush of claim 3 wherein the recycled wood pulp includes bamboo wood pulp.

5 . The biodegradable toilet brush of claim 1 wherein each of the fabric disks has a thickness of about 0.06 inches to about 0.12 inches.

6 . The biodegradable toilet brush of claim 5 wherein each of the fabric disks has a thickness of about 0.07 inches to about 0.10 inches.

7 . The biodegradable toilet brush of claim 1 wherein the fabric disks include:

upper fabric disks about 4⅓ inches in diameter, and

lower fabric disks about 3½ inches in diameter.

8 . The biodegradable toilet brush of claim 1 wherein at least one of the fabric disks has a plurality of blossoming slots extending radially inwardly from a perimeter of the fabric disk to achieve a blossom appearance of the brush head.

9 . The biodegradable toilet brush of claim 1 wherein the fabric disks are crumpled so as to form a roundish “blossom” shape for the brush head.

10 . The biodegradable toilet brush of claim 1 wherein:

a first plurality of the fabric disks is attached to the handle in position as an upper brush portion;

a second plurality of the fabric disks is attached to the handle in position as a lower brush portion;

the first plurality of fabric disks is slotted; and

the second plurality of fabric disks is unslotted.

11 . The biodegradable toilet brush of claim 10 wherein six radial blossoming slots are spaced at equal distances around a perimeter of each of the first plurality of fabric disks projecting radially inwardly toward a center of the fabric disk about ⅜ inch to about ¾ inch.

12 . The biodegradable toilet brush of claim 1 wherein:

the handle is made from cellulose material,

the handle is bowed, and

a length of the handle is configured to space apart a hand of a user of the biodegradable toilet brush from contact with toilet water while using the biodegradable toilet brush to clean a toilet.

13 . The biodegradable toilet brush of claim 1 wherein the handle is about ¼ inch to about ⅜ inch thick and about ½ inch to about ¾ inch wide.

14 . The biodegradable toilet brush of claim 1 wherein each of the two spaced pins extends through spaced holes in the handle near a top of the handle to hold the fabric disks in place on the handle.

15 . The biodegradable toilet brush of claim 1 wherein the central opening is a slot.

16 . A biodegradable toilet brush comprising:

a biodegradable handle including two spaced pins extending laterally through the handle; and

a brush head made of multiple layers of biodegradable fabric disks attached to and radiating outwardly from their attachment to the handle, wherein:

the two spaced pins are positioned to sandwich the fabric disks between the pins and hold the fabric disks in place while allowing the fabric disks to spread and extend outwardly into a ball shape,

at least some of the fabric disks have a plurality of blossoming slots extending radially inwardly from a perimeter of the disk to achieve a blossom appearance of the brush head, and

a length of the handle is configured to space apart a hand of a user of the biodegradable toilet brush from contact with toilet water while cleaning a toilet using the biodegradable toilet brush.

17 . The biodegradable toilet brush of claim 16 wherein:

a first plurality of the fabric disks is attached to the handle in position as an upper brush portion;

a second plurality of the fabric disks is attached to the handle in position as a lower brush portion;

the first plurality of fabric disks is slotted; and

the second plurality of fabric disks is unslotted.

18 . The biodegradable toilet brush of claim 17 wherein:

the fabric disks are made of biodegradable cellulose fibers;

each of the fabric disks has a thickness of about 0.06 inches to about 0.12 inches;

the handle is made from biodegradable cellulose material; and

the handle is about ¼ inch to about ⅜ inch thick and about ½ inch to about ¾ inch wide.

19 . The biodegradable toilet brush of claim 18 wherein each of the two spaced pins are configured to:

extend through spaced holes in the handle near a top of the handle; and

hold a plurality of the fabric disks in place on the handle.
