Claims12
A water-decomposable toilet cleaning brush configured to be coupled to a holder having a handle which water-decomposable toilet cleaning brush comprises:
- a cleaning part, at least a part of the cleaning part including a string formed by twining a water-decomposable fiber-interlacing nonwoven fabric;
- and
- a holding part comprising water-decomposable fiber-interlacing nonwoven fabrics that are adhered with a water-soluble adhesive,
- wherein the fiber-interlacing nonwoven fabric of each of the cleaning part and the holding part is decomposable in water in no greater than 700 seconds,
- wherein the water-decomposable cleaning brush is sufficiently small to allow the water-decomposable cleaning brush to be discarded by flushing the water-decomposable cleaning brush down a standard toilet after water decomposition, and
- wherein the string formed by twining the water-decomposable fiber-interlaced nonwoven fabric remains sufficiently stiff after bean wetted b water and before decomposition to perform a scrubbing action.

A method for manufacturing a water-decomposable toilet cleaning brush, which method comprises:
- forming each of a plurality of strings by twining a water-decomposable fiber-interlacing nonwoven fabric;
- and
- arranging the plurality of strings in a cleaning part and adhering at least a part of the strings to each other with a water soluble adhesive so as to form a holding part,
- wherein the fiber-interlacing nonwoven fabric is decomposable in water in no greater than 700 seconds,
- wherein the water-decomposable cleaning brush is sufficiently small to allow the water-decomposable cleaning brush to be discarded by flushing the water-decomposable cleaning brush down a standard toilet after water decomposition, and
- wherein the plurality of strings formed by twining the water-decomposable fiber-interlaced nonwoven fabric remain sufficiently stiff after being wetted by water and before decomposition to perform a scrubbing action.
