Definitions

  • the invention relates to devices, methods, and compositions for cleaning carpets, Fabric and upholstery. More specifically the invention relates to the use of pressurised aerosol containers for cleaning carpets, fabric and upholstery.
  • Fabric and carpet fibres are easily stained on contact with various soils such as perfumes, particulate matter, grease, oil, wine, food remains etc. Such stains are generally removed by compositions containing combinations of cleansing agents.
  • cleansing compositions such as fabric detergent powders, washing up liquid, floor cleaners, all of which may be suitable for use in cleaning stains from fabric and carpet, specialised carpet and upholstery cleaning compositions and devices have been developed.
  • US4,780,100 discloses foaming aqueous aerosol fabric cleaning composition for use in cleaning of carpets.
  • US4,561,992 discloses an aerosol cleaning agent for textile surfaces that contains plasticized urea formaldehyde resin foam particles in addition to propellant and other ingredients. The product is applied to textile upholstery, allowed to dry, then vacuumed away from the fabric.
  • US4,013,595 discloses a non-flammable aqueous aerosol rug cleaners using hydrocarbon propellants.
  • JP01-284299 discloses and aerosol container with a highly flammable stain removing liquid, where the aerosol is furnished with a stain removing tool furnished with bristles.
  • foaming cleaning compositions have a number of disadvantages.
  • the foams may contain high proportions of air, which can result in an incomplete contacting of stain with the product and thus lead to sporadic cleaning. Moreover, foam which is not completely removed from the surface can form residues which are undesirable and require additional cleaning. A further disadvantage is that the bulk of the foam may prevent the composition from effectively penetrating through carpet or fabric fibre.
  • a further disadvantage of prior art aerosol devices is that there is no control of the spread of the cleaning composition when applied to a stain, and so unsoiled portions of the surface to be treated may be unnecessarily contacted with the cleaning composition.
  • the user has little guidance as to how close or far to hold the aerosol composition from the surface to be cleaned, and there is the risk of composition splashing back from the surface being cleaned and contaminating the skin, eyes, or surrounding objects.
  • the user may hold the device too far from the surface to be cleaned to avoid such splashing, leading to ineffective penetration of the composition into the bulk of the carpet or upholstery or fabric.
  • BE-A-897 110 describes a device for applying a substrate to a surface comprising a pressurised container and an applicator head.
  • the present invention provides a device for cleaning a surface comprising:
  • the cleaning composition is stored in and dispensed from a pressured, corrosion resistant container that is equipped with a nozzle having an discharge orifice so that a jet of the composition can be directed at the surface to be cleaned.
  • Suitable containers or dispensers are known as aerosol containers and include a sealed chamber where a cleaning fluid and propellant are stored, and a hollow stem or tube having a distal end located within the chamber and a proximal end outside.
  • the proximal end is connected to a nozzle through a valve which must be actuated in order for dispensing of the cleaning composition to occur, the nozzle having an orifice appropriately dimensioned to provide a jet of cleaning composition having an approximately conical distribution pattern, wherein the semi-angle of the cone is suitably 20° or less, preferably 15° or less, more preferably 10° or less.
  • valves for use in the devices of the invention include valves such as the Koh-I-NoorTM PU foam valve VAV-1 with a 4mm outlet diameter and the LindalTM group PU45 valve with 4mm outlet diameter.
  • the valve is a metered valve, by which it is meant that when the valve is actuated, it opens for a predetermined time to release a jet of cleaning composition, then closes.
  • the pressurised container is pressurised with a gaseous component generally known as a propellant.
  • a gaseous component generally known as a propellant.
  • Preferred propellants for use in the invention are compressed air, nitrogen, carbon dioxide, other inert gasses, or hydrocarbons such as isobutene, butane 40, butane 70 or dimethyl ether.
  • the pressurised container may be of the type where a manually operated pump is used to provide an overpressure inside the container, by pumping air into the container to act as a propellant.
  • An alternative type of pressurised container that may be employed in the devices in the invention, includes a barrier or bag that separates the cleaning composition from the propellant.
  • a barrier or bag that separates the cleaning composition from the propellant.
  • Such "bag in can” pressurised containers are described in US4,260,110 . These have the advantage that the dispensing of cleaning composition from the pressurised container is independent of the orientation of container. These also have the advantage that they overcome any incompatibility problems between the propellant and the cleaning composition, as these are kept separate by the by the barrier or bag.
  • the pressurised container is such that when the valve is fully opened so that flow of the cleaning composition and propellant takes place through the nozzle, the discharge rate of the composition (including any propellant) is suitably from 20 to 100 gm/second, preferably from 25 to 80 gm/second, more preferably from 30 to 60 gm/second.
  • Such discharge rates give an effective penetration into the surface to be cleaned, while not leading to over rapid discharge and emptying of the pressurised container, such that the pressurised container may be small enough for easy handling yet contain enough cleaning composition for several treatments.
  • the pressurised container is preferably attached to the applicator head by an attachment means such that when the pressurised container is empty or nearly empty of cleaning composition and/or propellant, it can be easily replaced by the user. It is preferred that the applicator head is re-usable while the pressurised container is disposable.
  • the pressurised container is suitably provided with a lip or rim around its perimeter towards the nozzle end of the container. This allows for engagement with an attachment means such as a resilient groove or collar or lip on the interior surface of the cleaning head of the device, whereby the applicator head of the device can be firmly yet removably attached to the pressurised container.
  • the pressurised container may be furnished with other attachment means, such as a male screw thread which may engage with a female threaded collar on the applicator head.
  • the nozzle of the pressurised container situated at the distal end of the container, is arranged such that when the valve is opened, the jet of cleaning composition is fired substantially along the long axis of the pressurised container, i.e. in a direction normal to the end plate of the pressurised container, into the entrance orifice of the applicator head.
  • the pressurised container is mounted to an applicator head.
  • the applicator head may be in the form of a rigid containment skirt directly mounted onto the nozzle of the pressurised container, and a valve actuated by pressing the nozzle towards the pressurised container is employed, such that the valve is actuated and a jet of cleaning composition is released by pressing the containment skirt towards the nozzle and the pressurised container.
  • the applicator head may comprise an attachment collar mounted to the pressurised container, and a rigid containment skirt mounted to the attachment collar.
  • the containment skirt will be furnished with a entrance orifice at its waist, aligned with and surrounding the discharge orifice of the nozzle such that when the valve is actuated, a jet of cleaning composition may exit from the discharge orifice, through the entrance orifice of the skirt, towards the central region of the plane formed by the rim of the containment skirt.
  • the actuation of the valve may be by pressing the waist of the containment skirt against the nozzle, as described above, or the applicator head may be furnished with a separate, manually operated trigger used to actuate the valve and release a jet of cleaning composition.
  • the device is furnished with a child-proof lock to prevent accidental operation of the device.
  • the rigid containment skirt may be of any suitable shape, provided that at its proximal end it is provided with a entrance orifice it is adapted to align with the discharge orifice of the nozzle of the pressurised container, such that the jet of composition released when the valve is actuated entirely enters the region surrounded by the wall or walls of the containment skirt.
  • the skirt may be in the form of a frustum of a cone or pyramid of cylindrical, polygonal or elliptical section, widening out from its proximal and to its distal end, the distal end being in the form of a planar rim.
  • the skirt may be a hollow tube, of polygonal, circular or elliptical cross section, open at the distal end to form a planar rim, and closed at the proximal end save for the entrance orifice.
  • the walls of the containment skirt are suitably formed from a rigid polymer such as polyethylene or polystyrene, and are solid.
  • a rigid polymer such as polyethylene or polystyrene
  • the rim of the containment skirt has a maximum diameter of 25cm or less, preferably 20 cm or less, more preferably 15cm or less.
  • maximum diameter is meant the diameter of the smallest circle that would entirely enclose the rim of the containment skirt.
  • the containment skirt is arranged such that its distal rim is substantially normal to the flow direction of the jet of cleaning fluid, and such that the jet is directed substantially towards the centre of the area defined by the rim.
  • the distance between the discharge orifice and the centre of the area defined by the rim, measured along the direction of the jet of cleaning composition, is suitably from 0.2 to 25 cm, preferably from 0.3 to 20 cm, more preferably from 0.5 to 15 cm.
  • the waist (proximal) end of the containment skirt is slidably mounted in a collar, the collar being removably mounted to a pressurised container at the collar's proximal end, such that the surface of the waist surrounding the entrance orifice of the containment skirt can press against the surface of the nozzle surrounding the discharge orifice.
  • the two surfaces are provided with a means, such as a tongue and groove, such that they can mate together to give a fluid-tight seal.
  • the valve is connected to the nozzle and is adapted to discharge a jet of cleaning composition through the entrance orifice of the containment skirt when the nozzle is pressed by the surface of the waist of the containment skirt, towards the body of the pressurised container.
  • the device is used by pressing the rim of the containment skirt flat against the surface to be cleaned, defining a region to be cleaned such that the valve is actuated and a jet of cleaning composition is directed towards the centre of the region to be cleaned.
  • the pressurised container may be enclosed within a housing sheath, the housing sheath having the applicator head at its distal end and a handle comprising a trigger at its proximal end.
  • the user grasps the handle and when the trigger is pressed, this is adapted to push the pressurised canister along the sheath towards the applicator head at the distal end of the sheath, causing the entrance orifice of the applicator head to depress the nozzle towards the end plate of the pressurised container, opening the valve and releasing a jet of cleaning composition.
  • This arrangement has the advantage that the trigger may be provided with a child-proof locking arrangement to prevent accidental triggering of the release of the jet of cleaning composition.
  • the cleaning composition to be used in the invention is a liquid with a kinematic viscosity (as measured by capillary viscometer) at 25°C of 10000 mm 2 sec -1 or less, preferably 3000 mm 2 sec -1 more preferably 1000 mm 2 sec -1 or less. These preferred viscosities ensure that the composition penetrates soft surfaces such as fabric, upholstery and carpet, readily lifting soil.
  • composition of the cleaning composition does not include in the calculation of percentage by weight any propellant which may be dissolved or dispersed in the cleaning composition when the composition is place along with propellant in the pressurised container.
  • the cleaning composition is preferably an aqueous composition, by which it is meant that it comprises 60% or more by weight of water, preferably 70% or more, more preferably 80% or more.
  • the composition comprises less than 99% by weight of water.
  • the cleaning composition is a non-foaming composition.
  • any foam generated when the composition is agitated is unstable and collapses within 1 minute of ending agitation, preferably within 30 seconds, more preferably within 10 seconds. This may be suitably measured by placing 100 ml of composition in a 500ml beaker and whisking it for 30 seconds with a food mixer.
  • the cleaning composition may comprise an anti-foaming agent, such as a polydialkylsiloxane oil, at a level from 0.1 to 2% by weight, preferably 0.2 to 1% by weight, in order to suppress foaming.
  • the cleaning composition suitably comprises one or more cleaning agents selected from but not limited to surfactants, solvents, enzymes, bleaching agents, germicidal agents, polymers and chelating agents.
  • the cleaning composition suitably comprises from 0.05 to 10% by weight of surfactant selected from anionic surfactant, cationic surfactant, amphoteric surfactant, zwitterionic surfactant, non-ionic surfactant and mixtures thereof.
  • surfactant selected from anionic surfactant, cationic surfactant, amphoteric surfactant, zwitterionic surfactant, non-ionic surfactant and mixtures thereof.
  • Suitable surfactants for use as cleaning agents are present at a level to aid in soil removal without generating excessive foam.
  • non-ionic surfactants particularly alcohol alkoxylates.
  • Particularly preferred are the low-foaming ethoxylate/propoxylate non-ionic surfactants.
  • An organic solvent may be present as 0.1 to 10% by weight of the cleaning composition, preferably 0.2 to 6%, more preferably 0.3 to 4%.
