Definitions

  • the present invention relates to a cleaning device according to claim 1, especially for cleaning containers with permanent water volume, as toilet bowls and the like.
  • the invention further relates to a container containing a single dosage of cleaning material according to claim 11.
  • toilet bowls are typically one of the most undesirable jobs for most persons. Nevertheless, toilet bowls must be kept clean in order to prevent sanitary problems, the potential for irritable smells, and the possibility of harmful bacteria buildup.
  • bowl cleaning products are known. Such products typically fall within two categories, namely, cleaning by hand with a bowl cleaning device or with automatic "in tank” or “in bowl” cleaners.
  • Automatic "in tank” or “in bowl” cleaners comprise cleaning material in the form of a slowly dissolving block or tablet or of a gel or liquid disposed under the rim of the toilet bowl or in the water container. These automatic cleaners dispense a dosage of cleaning material upon flushing of the toilet.
  • they are generally not as effective as manual scrubbing. Therefore most consumers typically supplement such automatic cleaners with hand scrubbing and cleaning.
  • Hand cleaning typically takes the form of a toilet cleaning brush or sponge.
  • Most users apply a certain dosage of liquid cleaning material or cleaning powder, stored in a bottle or a container, to the surface of the toilet bowl. The right dosage has to be estimated by the user.
  • Most people wanting a sufficient cleaning result tend to apply an overdose. This may cause foam development that can' t be flushed in one go and more burden to the environment than necessary.
  • most bottles respectively containers do not allow dosing the cleaning material exactly, as their openings are often wide, dispensing the cleaning material in one splash.
  • Some products have angled nozzles to reach under the rim of the toilet but these till result in a lot of the cleaning liquid running into the bowl water and not remaining in the area needed to be cleaned.
  • cleaning powder kept in bottles or other containers tends to agglomerate in the humid bathroom atmosphere when the bottle is not closed properly.
  • most containers have a safety cap the material contained is a danger to children who manage to open it.
  • An inventive cleaning device comprising a cleaning head, a handle adapted to receive at least one single dosage of cleaning material and delivering means operable, in use, to deliver a single dosage of cleaning material into the cleaning head and to release the cleaning material from the cleaning head has the advantage that a well defined dosage of cleaning material is delivered directly to the cleaning head and is thereby dispensed directly at the surface which is to be cleaned. Further, no manual contact with the cleaning head is necessary. This ensures that the highest concentration of active material, i.e. the cleaning formulation or composition, is within bristles, a sponge, closed-cell phenolic foam or other medium acting as use surface for cleaning or scrubbing, and the material is then distributed from there respectively by them.
  • the active material is used more efficient than when poured directly onto the surface, from where it is at least partially dissolved and flushed without being used for cleaning.
  • a well defined dosage of active material is applied to the surface, ensuring optimum cleaning action at minimum expenses and minimum release of substances burdening the environment.
  • the dosage may be adjusted to the application, e.g. toilet bowl cleaning, by providing containers with a respective volume and/or concentration of active material.
  • a further advantage is that the user does not need to handle the material itself.
  • a single material dosage is preferably contained in a container or a tablet which is easy, safe and clean to handle. Even with liquid materials no spilling can occur as the active material is contained in a closed container and released from the cleaning head, without the user touching it directly.
  • Another advantage is that with the cleaning formula coming from within the brush, it keeps the brush itself clean and prevents germ attraction.
  • the inventive device is preferably used for, but not restricted to cleaning surfaces of containers with a permanent water volume.
  • Cleaning material is preferably inserted in the form of a material tablet or contained in a cartridge-like container, whose walls consist of water soluble material, preferably Polyvinylalcohol (PVA) , which is preferably low-temperature dissolving.
  • PVA Polyvinylalcohol
  • Water reaching the cleaning material contained in the device through openings in the cleaning head dissolves or disintegrates the active cleaning material and/or its container.
  • a liquid, e.g. a solution, suspension or dispersion, containing cleaning material is then released through the same openings.
  • the container walls dissolve completely during the time normally required for a cleaning action such that, after cleaning the surface, the device is ready for the next use without the need for rinsing or cleaning it.
  • a material tablet the features of the cleaning composition are chosen such that the tablet is completely decomposed under the influence of water during the typical cleaning time, e.g. 30 seconds.
  • the cleaning material itself is not necessarily water soluble, but can for example contain abrasives.
  • the handle comprises an at least partially hollow shaft extending to the cleaning head and forming a passage for insertion and delivery of the single dosage of cleaning material.
  • the handle further comprises a rod dimensioned to slide within the passage for pushing the single dosage of cleaning material into or next to the cleaning head.
  • the single dosage of cleaning material can be inserted at or near the top end of the handle, respectively a portion of the device which is not in direct contact with the surface to clean, at a distance from the cleaning head.
  • the insertion area is clean and dry, and the inserted active material is delivered into the cleaning head without the need for manual handling or touching the device near the cleaning head.
  • the device further comprises a spring acting to push the rod to the bottom of the passage.
  • the diameter of rod and passage are designed such that the passage fits tightly around the rod, while the rod is able to slide within the passage. Thereby water is prevented from entering an upper portion of the passage, thereby ensuring that the inside of the passage is dry, and a water soluble cartridge inserted into the passage does not get stuck in the passage.
  • the rod can comprise a gasket to seal the passage respectively its upper part off from the wet inside of the cleaning head.
  • the cleaning device comprises a cutting edge, e.g. a spike, located in the device, preferably at a bottom end of the passage.
  • This edge facilitates cutting or piercing a cartridge-like container inserted into the device, wherein the container contains the single dosage of cleaning material as powder or liquid detergent. This has the advantage that the container is pierced when pushed into the device, immediately releasing the cleaning material.
  • the inventive container or cartridge contains a single dosage of non-aqueous or anhydrous powder or liquid cleaning material and is made of a water soluble foil.
  • the water soluble foil consists of a Polyvinylalcohol (PVA) which is preferably low-temperature dissolving.
  • PVA films supplied by the following suppliers can be used: Aquafilm ltd. (AQUAFILM) , Environmental Polymers ltd. (EP POLY), Cris Craft Inc. (MONO-SOLO®).
  • the container preferably has a cylindrical shape, preferably with a circular cross section. Cartridges like this are easy to manufacture from a sheet material or a flexible tube.
  • sachets are constructed from a tube that is sealed at the ends, e.g. twisted or heat sealed. This methods results in no flanges around the edge, i.e. the surface in contact with the tube is free of excess PVA.
  • the diameter of the cartridge ranges from 10 to 40 mm, preferably around 25 to 35 mm.
  • the length of the cartridge ranges from 30 to 80 mm, preferably around 45 to 55 mm.
  • the cartridge has an internal volume of approximately 1.5 to 43 cm 3 , preferably around 18 to 20 cm 3 .
