Abstract

A toilet cleaner ( 1012 ) is mounted on a cleaning device and cleaning is effected by bristles ( 1034 ) and scrapers ( 1052, 1053 ). The toilet cleaner ( 1012 ) is discharged from a cleaning device by a pusher on that device sliding down and knocking the toilet cleaner off. The toilet cleaner ( 1012 ) is flushed down the toilet with water flowing through the hollow toilet cleaner and out of an opening ( 1082 ) at the leading end of said toilet cleaner. The toilet cleaner ( 1012 ) then degrades or dissolves and is biodegradable.

Claims

exact text as granted — not AI-modified
1 . A toilet cleaner including water degradable plastics.  
   
   
       2 . A cleaner as claimed in  claim 1  in which the plastics include polyolefin.  
   
   
       3 . A cleaner as claimed in  claim 1  which is integrally formed.  
   
   
       4 . A cleaner as claimed in  claim 1  which is injection moulded.  
   
   
       5 . A cleaner as claimed in  claim 1  in which the cleaner includes a plurality of projections arranged, in use, to effect cleaning.  
   
   
       6 . A cleaner as claimed in  claim 5  in which the remote ends of at least some of the projections define a plane.  
   
   
       7 . A cleaner as claimed in  claim 5  in which the projections extend from at least one side of the cleaner.  
   
   
       8 . A cleaner as claimed in  claim 7  in which at least a first set of projections define a plane along a common edge.  
   
   
       9 . A cleaner as claimed in  claim 8  in which that plane includes a first side edge of the cleaner.  
   
   
       10 . A cleaner as claimed in  claim 5  in which at least some of the projections have a length to the remote end when compared to the average surface area along the extend of the projection of more than 2:1.  
   
   
       11 . A device as claimed in  claim 5  in which the projections comprise bristles.  
   
   
       12 . A cleaner as claimed in  claim 1  in which the cleaner includes a first and a second end being arranged such that, under water flow, the first end is arranged to lead with the second end trailing.  
   
   
       13 . A cleaner as claimed in  claim 12  in which the cleaner includes a channel extending therethrough.  
   
   
       14 . A cleaner as claimed in  claim 13  in which the cleaner includes a channel extending therethrough.  
   
   
       15 . A cleaner as claimed in  claim 13  in which the channel is substantially enclosed with an opening at either end.  
   
   
       16 . A cleaner as claimed in  claim 15  in which the opening at the first end is of less cross-sectional area than the opening at the second end.  
   
   
       17 . A cleaner as claimed in  claim 1  in which the cleaner includes at least one scraper.  
   
   
       18 . A cleaner as claimed in  claim 17  in which the cleaner includes two scrapers.  
   
   
       19 . A cleaner as claimed in  claim 17  in which one scraper is arranged to project from the front region, in front of the cleaner.  
   
   
       20 . A cleaner as claimed in  claim 17  in which at least one scraper extends from the front region to the side of the cleaner.  
   
   
       21 . A cleaner as claimed in  claim 1  in which the cleaner has been treated to soften the cleaner prior to use.  
   
   
       22 . A cleaner as claimed in  claim 21  in which the cleaner has been treated to soften one portion of the cleaner more than another portion.  
   
   
       23 . A cleaner as claimed in  claim 1  arranged, in use, to be detachably mounted on a cleaning device including a handle.  
   
   
       24 . A cleaning device including a handle and means to engage a cleaner as claimed in  claim 1  and a pusher mounted on the device arranged, in use, to push the cleaner engaged by the device off the device.  
   
   
       25 . A device as claimed in  claim 23  in which the guide constrains the pusher to move relative thereto in generally one direction only.  
   
   
       26 . A device as claimed in  claim 24  in which the guide includes a stop arranged to restrict the extent of movement of the pusher in the direction towards where a cleaner is arranged to be engaged.  
   
   
       27 . A device as claimed in  claim 26  in which the pusher includes a portion arranged to extend beyond the stop when the pusher engages the stop.  
   
   
       28 . A device as claimed in  claim 24  in which the pusher is normally retained on the device and spaced from where a cleaner is arranged to be engaged by the device.  
   
   
       29 . A device as claimed in  claim 28  in which the pusher is in contact with the handle.  
   
   
       30 . A method of cleaning a toilet comprising cleaning the toilet with a plastics cleaner and causing the cleaner to degrade in water.  
   
   
       31 . (canceled)
