  • a handle having, at the remote end thereof, a cleaning device.
  • a head of a device is slipped into a swab and a toilet is then cleaned by wiping the swab around the surface of .the bowl of the toilet. Removal of the swab is achieved by shouldering the swab against the rim of a toilet bowl and pulling the holder away to cause the swab to slip off, into the bowl, and dissolve prior to being flushed away.
  • US 5 471 697 discloses a toilet cleaning device that has a cleaning head in the shape of a foot. This head is able to clean .underneath the rim of the toilet.

As there is only a limited surface area contact between the holder and the cleaner less force is required to push the cleaner off the holder.
  • the handle is manoeuvred' as previously described with the bristles effecting a large part of the cleaning.
  • the cleaner includes two scrapers 1052 and 1053.- These primarily scrape at their remote free edge. However, it is possible that their side edges may also achieve some cleaning effect by scraping.
  • the bristles (or any bristles as herein referred to) may be flexible to start with or may change from being rigid to being flexible during cleaning.
  • the laterally extending scraper 1053 will primarily scrape the sides of the bowl, including the sides beneath the water level.
  • the scraper 1052 will scrape the bottom of the toilet, beneath the water level. This is a region that requires a vigorous cleaning action -and a user is able to push down in a mechanically advantageous way with ' the force being transmitted primarily or solely along the axis of the holder. Consequently as there are minimum bending forces on the holder a greater force can be applied without risk of damage to the holder.
  • the lateral scraper 1053 may effect a scraping action and, alternatively or additionally the bristles 1034 may effect a cleaning .action.
  • the sides of the scrapers may also effect a cleaning action.

  • the bristles are 15 mm long and 2 mm in diameter.
  • Removal of the cleaner from .the holder is as previously described. However, -the region of the holder that the ejector will hit includes a rim 1080 projecting around the periphery. Consequently, should the cleaning continue for some time and should there be some softening of the cleaner, the rim will maintain sufficient integrity to enable ejection to occur. Indeed it may be advantageous for some softening of the bristles to occur during cleaning to enable ' different cleaning effects to take place with a vigorous brush and scrape initially taking place and with a subsequent soft, sweep or wipe of the bristles .
  • the cleaner As already mentioned is hollow.
  • the end of the cleaner adjacent to the fins includes a small opening 1082.. Initially this opening 1052 assists in the cleaner sinking or being semi submerged. However, if the cleaner has not completely dissolved in the bowl (which in this instance it ' is not intended to) upon flushing the toilet the water will flow through the hollow cleaner and out through the narrow opening 1082. As the water bears against the internal end face of the cleaner that defines the opening and pushes through the opening 1082 the cleaner will be aligned to flow, with the fin 1052 leading, around the U-bend and into the sewer.
  • the cleaner 1012 or any of the pads or cleaners herein referred to may have any of the following features such as subsequently being fully biodegraded, perhaps over a period of a few hours.
  • Any of the pads or cleaners may comprise a monomer or a copolymer or both.
  • the cleaner may for instance comprise polypropylene or polyvinylalcohol or a mixture thereof.
  • An additive which may comprise polyvinylalcohol may be included to assist in the degradation of such material and the additive may be in any proportion such as less than 50 or 30 or 20 or 10 or 5 or in the region of 3% by weight of the cleaner.
  • the additive may also prevent the cleaner from being too rigid or brittle.
  • a highly preferred polyvinyl alcohol polymer is W63B which may be obtained from PVAXX Research and Development of Unit 4, Dovecote Workshops, Barnsley Park Estate, Cirencester, United Kingdom. GL7 5EG.
  • the cleaner may be treated before use or sale. For instance the cleaner may be hot treated such as by being in contact such as by immersion in water. Alternatively the cleaner may be liquid or cold treated or both such as by being in contact for example by immersion in water. These treatments may be to soften the cleaner or to make the cleaner more pliable. The cleaner, possibly as a result of these treatments, may retain the scrapers relatively rigid and may make the bristles relatively soft.
  • Aroma such as air freshener may be included in the plastics such that this aroma is given off during cleaning, possibly as degradation of the cleaner commences.
  • detergent may be provided with or in the material of the cleaner with that detergent being arranged to be given out during cleaning.
  • Cleaners having detergent or different properties from other cleaners may be coded such as colour coded.
  • the holder and or the head may be of any material such as of polypropylene.
  • the handle may be of the same or a different material from the holder or the ejector.
  • the holder is curved such as about an arc.
  • the ejector may have an arcuate opening enabling sliding of the ejector along the holder.
  • the holder may be flexible along at least part of its length.
  • the distal end of the holder in the region where the cleaner is located may be able to have its orientation relative to the handle altered such as by moving between at least two positions such as by pivotal movement. . That movement may be effected by actuation of a device in the region of the handle or by pressure exerted on the cleaner. The orientation may be able to return or move to a position in which ejection may take place. This arrangement may assist in reaching the most inaccessible parts of a toilet.
  • the device may be adjustable in length. This may allow the device to be used in different applications or, alternatively or additionally, to ' be stored in a short configuration and then to be extended when in use, such as to one or more than one effective length.
  • the device may be able to be retained in an effective length or lengths such as by being releasably retained.
  • the device may include a telescopic arrangement.
