Water Disposable Head Comprising Plural Water Disposable Materials

Abstract

A head for cleaning a target surface, such as a toilet bowl. The head has a longitudinal axis and comprises a starch based material. The material may be provided as a sheet, and formed to make a generally round head or a head of laminae. The head may optionally contain granules, which optionally define a core and improve the stiffness of the head. The starch based material may be extruded to have a machine direction oriented in the longitudinal direction of the cleaning device.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to cleaning devices and more particularly to cleaning devices suitable for cleaning a wet target surface. The device may comprise a cleaning head removably attachable to a handle.BACKGROUND OF THE INVENTION[0002]Devices for cleaning dirty and unsanitary areas are well known in the art. Typically such devices have a cleaning head for contacting and cleaning the surface of the unsanitary area. The head may be attached to an elongate handle, so that the user's hand is remote from, and does not contact, the dirty and unsanitary surface during cleaning. Typical target surfaces include a toilet, sink, countertop, floor, or other hard surface.[0003]One example of such a device is a toilet brush. The toilet brush may have bristles at one end which are immersed in the toilet bowl, often times with cleanser. The cleanser may be separately dispensed into the toilet bowl. Dual brush heads may be employed, as taught by U.S. Pat. No. 5...

AI Technical Summary

Problems solved by technology

However, these attempts do not overcome the problems encountered after the cleaning task is finished.

However, the toilet brush may be wet, and unsanitary even if rinsed.

The toilet brush may have an unpleasant smell and / or breed germs.

The head may be discarded after a single use, obviating the need to store that head under unpleasant and / or unsanitary conditions.

However this attempt simply moves the unsanitary head from storage to a disposable bag.

Commercial embodiments of cleaning brushes having a head with sheet material have not been well accepted, apparently because the sheet material does not provide enough cleaning power to be efficacious.

WO 2009 / 080130 acknowledges this drawback in a cleaning device having paper material, and even paper material impregnated with detergent.

But these materials are known to slowly dissolve, leading to difficulty with flushing.

Again, it is unlikely the paper will provide sufficient cleaning power to be efficacious.

However none of the aforementioned attempts in the art overcome the dueling problems of providing flushability with sufficient cleaning power to be efficacious.
