Definitions

  • the present invention relates to cleaning apparatus, and to a method of cleaning using such apparatus. It relates particularly, though not exclusively, to an apparatus and method for cleaning a toilet bowl.
  • Known toilet brushes have a handle to one of which is fixedly attached a brush head.
  • the toilet brush is normally stowed upright, brush lowermost, in a cylindrical housing, from which it is withdrawn, for use. There is no provision for replacing the brush head.
  • Such articles are perceived as being unpleasant to use, and unhygienic.
  • Toilet brushes have been proposed, with brush heads that are replaceable, at least in part.
  • a toilet brush with a removable cleaning sleeve which fits over a bristle head.
  • WO 01/43618 there is described a cleaning device having a disposable cleaning head, which dissolves in liquid so that it can be flushed away after use.
  • the cleaning head is shown as having a series of parallel tubes.
  • a refill package is shown, having an array of cleaning heads, arranged side-by-side.
  • the bulk of the refill package, with its array of cleaning heads, themselves individually bulky, is a significant practical disadvantage, and an impediment to the commercial utilisation of the device.
  • a cleaning assembly comprising a cleaning article and a housing for stowing the cleaning article, wherein the cleaning article has a handle and a cleaning head, the cleaning head being releasably located at the distal end of the handle, wherein the housing contains a stack of replacement cleaning heads.
  • stack denotes that the housing contains a collection of cleaning heads having a vertical dimension; as distinct from the side-by-side arrangement of WO 01/43618.
  • a stack may comprise a collection of cleaning heads in a linear array, preferably in a substantially vertical column, one above the other.
  • a stack may comprise a collection of cleaning heads extending in three dimensions.
  • the cleaning heads could be arranged in a repeating three-dimensional array but preferably form a random heap.
  • the handle is stowed in the housing without a cleaning head attached thereto.
  • the handle is stowed in the housing in a compartment which does not contain cleaning heads.
  • the housing provides a first zone for stowing the cleaning article (or, more preferably, just the handle thereof) and a second zone for storing a stack of replacement cleaning heads.
  • those zones are separated by an impermeable upright barrier.
  • a housing may be designed for storing a plurality of stacks of replacement cleaning heads.
  • the cleaning head at the distal end of the handle may be released by a mechanical action of the user applied remotely from the cleaning head.
  • a release mechanism which includes an actuator located at or towards the proximal end of the handle.
  • the actuator is coupled to a rod having one or more prongs at its distal end.
  • the user advances the rod and drives the prong(s) into a replacement cleaning head, to couple it to the handle.
  • they may be flexible, and may splay, as they enter the cleaning head.
  • the reverse movement retracts the rod and withdraws the prong(s) from the cleaning head when it is to be replaced. Preferably it can then fall from the handle, into the toilet bowl, and be flushed away.
  • the user causes a rod to rotate and the rod has a screw or auger-type head to engage the cleaning head. Reverse movement withdraws the auger-type head from the cleaning head, allowing the latter to fall away.
  • the user causes a pinching action at the distal end of the handle, and by means of this pinching action the replacement cleaning head may be engaged.
  • the pinching action ceases and the cleaning head can drop away from the handle, into the toilet bowl, and be flushed away.
  • the cleaning head may have a projection which is the part to be pinched, to assist this operation.
  • the cleaning heads are of a shape such that they can be stacked together compactly.
  • there is a projection from one surface there may be a complementary recess in the opposite surface.
  • a cleaning head when released it may drop from the handle without the user having to touch it.
  • a replacement cleaning head can be engaged without the user having to touch it.
  • the user may cause a used cleaning head to be released from the handle and a replacement cleaning head to be coupled to the handle by a mechanical action. In certain embodiments this may be a purely mechanical action.
  • a purely mechanical action may involve the user applying a force throughout the action.
  • it may be of a type such that one mechanical action may store energy (for example in a spring) which can assist the following mechanical action.
  • the action of releasing the head may store energy in a mechanism which can "drive” or assist the subsequent action, of engaging the replacement head; or vice-versa.
  • the release or coupling of a cleaning head may occur by an electro-mechanical action, preferably with the user initiating the release or engagement action and some or all of the rest of the release or engagement action being electrically driven (for example by a motor or solenoid).
  • the power source is one or more electrical batteries.
  • the cleaning assembly is designed to minimise the risk of contact of the handle with the cleaning heads, other than the replacement cleaning head selected.
  • One way in which this can be done is by providing the cleaning heads in a substantially vertical column, with the top cleaning head always being the replacement cleaning head. Lower cleaning heads are screened by the cleaning heads above them.
  • Another way is by causing the cleaning heads to move, one by one, to a location at which they can be engaged by the handle, and at which the other cleaning heads are not contactable by the handle. This may be achieved by the gravity feed of cleaning heads to the said location.
  • the housing has an outlet at its base, of size to pass one cleaning head at a time, and a tray carried externally of the outlet, of size to accommodate one cleaning head at a time.
  • a housing has within it an inclined wall or a chute, to assist the cleaning heads to pass through the outlet.
  • the cleaning heads comprise a body of a material, for example a pad, preferably somewhat compressible but substantially able to hold its shape when used in a scrubbing or rubbing action. It may suitably be of plastics and/or foam and/or fibrous material.
  • Suitable materials for the cleaning heads include synthetic thermoplastics material, for example polyvinyl alcohol, and biopolymer materials, for example cellulosic materials or starch-derived materials, and a mixture of a synthetic thermoplastics material and a biopolymer material, able to be compounded to yield a satisfactory material.
  • synthetic thermoplastics material for example polyvinyl alcohol
  • biopolymer materials for example cellulosic materials or starch-derived materials
  • a mixture of a synthetic thermoplastics material and a biopolymer material able to be compounded to yield a satisfactory material.
  • the cleaning heads may comprise a plastics wall having an outer cleaning surface, for example non-woven fabric or loose fibres adhered to the plastics wall.
  • the cleaning heads may comprise a plastics wall having an outer cleaning surface, for example non-woven fabric or loose fibres adhered to the plastics wall.
  • a cleaning head When a cleaning head is of a plastics material it maybe a homogeneous part, for example formed by moulding, or it may be in the form of pieces cohered together.
  • the cleaning heads may be provided on their outer surface with an abrasive material, for example bonded hard particles.
  • the cleaning heads may have a textured outer surface. This may be the result of a moulding process or of the material used. For example an outer fabric of honeycomb pattern may be used; or a filament of material, for example of a thermoplastics or a natural material, may be wrapped repeatedly around the cleaning head to form the textured outer surface.
  • the cleaning heads do not comprise bristles.
  • the cleaning heads are of a material which is degradable in water.
  • the cleaning heads are of a material which dissolves or disintegrates in still water at ambient temperature (preferably 20°C), in not more than 24 hours, more preferably not more than 2 hours, and most preferably not more than 30 minutes.
  • the cleaning head may be such as to both disintegrate and dissolve in water.
  • the cleaning head may be designed to disintegrate before complete dissolution is achieved.
  • it may be a compact of hydrosoluble pieces and after a period of contact with water it may fall apart into those pieces, which subsequently completely dissolve.
  • the cleaning head may comprise a material or component which causes it to be non-buoyant in water.
  • the cleaning head may comprise a superabsorbent material, for example a superabsorbent polyacrylate.
  • the cleaning head may comprise a superabsorbent material, for example a superabsorbent polyacrylate.
  • the maximum length of the cleaning heads does not exceed their maximum width. More preferably the maximum length is not more than one-half of the maximum width.
  • the cleaning heads are of generally rounded form or, most preferably, of oblate or lozenge form.
  • the cleaning heads may comprise a supporting core which has better mechanical properties than the surrounding part which comprises a cleaning surface.
  • the supporting core may, relative to the surrounding part, be stiff, or harder, or tougher.
  • the cleaning article may include a cleaning agent. This may be a cleaning agent of liquid form.
  • the cleaning heads could be supplied impregnated with a liquid cleaning agent.
  • the cleaning article could contain a reservoir of cleaning liquid.
  • the liquid could be dispensed onto the cleaning head. Alternatively, or additionally, it could be dispensed directly onto the surface being cleaned.
  • the dispensing of the liquid could be under the control of the user, for example by operation of a lever. Alternatively the dispensing could be caused by the engagement of the cleaning article with the substrate to be cleaned. The resulting compressive force applied to the handle could cause an aliquot of cleaning liquid to be dispensed.
  • the cleaning agent could be a solid, in particular a particulate cleaning agent carried by the cleaning head.
  • a particulate material may be selected which dissolves when applied to a surface during cleaning, when water is present. It may effervesce as it does so.
  • a solid cleaning agent could include an abrasive.
  • the cleaning agent could include an anti-bacterial agent.
  • the anti-bacterial agent could be compounded into the material of the cleaning head or it could be applied thereto, as a liquid, gel or solid.
  • a housing per se containing a stack of cleaning heads for use with a cleaning article which is not itself part of or stowed in the housing.
  • a cleaning article comprising a handle and a cleaning head of generally rounded or oblate or lozenge form at the distal end of the handle, wherein the handle is adapted to release a used cleaning head and accept a replacement cleaning head at its distal end, by the agency of a user but without the user having to touch the used cleaning head or the replacement cleaning head.
  • a cleaning head per se adapted for temporary securement to a handle, degradable in water, and having a maximum length which does not exceed its maximum width.
  • a method of cleaning a hard surface for example the inside surface of a toilet bowl, using a cleaning assembly of the first aspect or a cleaning article of the third aspect or a cleaning head of the fourth aspect.
  • a toilet cleaning article (intended to replace a conventional toilet brush) is shown. It comprises a tubular handle 2, and, at the distal end of the handle, a cleaning head 4.
  • the handle is provided with a mechanism for securement of the cleaning head 4.
  • a rod 6 is located within the handle and terminates at the distal end in splayable prongs 8.
  • the splaying of the prongs is assisted by an angle piece 10 at the distal end.
  • the prongs pass between this angle piece and a flared end region 12 of the handle. As a result, the prongs are forced into the cleaning head 4.
  • the cleaning head 4 is of generally lozenge-form.
  • the rod 6 terminates in a domed part 14.
  • a cross wall 16 within the handle, and between the domed part 14 and the cross wall 16, there is a helical spring 18.
  • a resilient depending arm 20 Carried by the domed part 14 is a resilient depending arm 20 having a button 22 which co-operates with two openings 24, 26 in the wall of the handle, adjacent to the proximal end.
  • Fig. 1B The position shown in Fig. 1B is the normal operative position.
  • the prongs 8 are firmly located within the cleaning head 4.
  • the rod 6 is in an advanced position.
  • the spring 18 is compressed.
  • the button 22 is retained within the lower opening 26.
  • the cleaning head of Figs. 1A to 1C is of a polymeric material which is 50:50 (w:w) compound of polyvinyl alcohol and cellulose, which disintegrates and dissolves in water in the circumstances to be described.
  • Figs. 2A-2C show an alternative arrangement differing from that of Figs. 1A-1C primarily in that the cleaning head is not pierced by prongs, but pinched by jaws.
  • the cleaning head again generally of lozenge-form, has a central nipple-like projection 28 on one side. It also has a lower recess 29, able to snugly receive the projection of the adjacent cleaning head, such that cleaning heads may form a stable and compact vertical column.
  • a helical spring 34 is trapped between the proximal end face 36 of the handle and an uppermost abutment 38 carried by the rod 30.
  • a cleaning head In normal use (Fig. 2B) a cleaning head is securely gripped.
  • the rod is in its most advanced position and the helical spring 34 is not compressed.
  • To remove a cleaning head the rod is retracted by means of a slider 40, coupled to the rod 30 but located outside the handle.
  • the spring 34 is compressed.
  • the arrangement at the distal end is such that the jaws 32 open, and the cleaning head falls into the toilet bowl (Fig. 2C).
  • the handle is then located on a replacement cleaning head (Fig. 2A) and the rod caused to advance, with the assistance of the spring 34 as it relaxes. When this happens the jaws 32 close, so gripping the protuberance 38.
  • the jaws 32 are held in that position until the slider 40 is released, to retract the rod.
  • the cleaning head of Figs. 2A to 2C is of a biopolymeric material.
  • it is of a cellulosic material compounded 50:50 (w:w) with polyvinyl alcohol, and designed to disintegrate in water under the conditions of use.
  • Fig. 3A shows a cleaning assembly which includes a cleaning article according to Figs. 1A-1C, and replacement cleaning pads.
  • the cleaning assembly comprises a housing 42 of trigonal form, in which three main compartments are divided, by means of upright radial walls, set at 120 ° to each other.
  • the cleaning article (whose handle is shown as 44 protruding upwardly from the housing) has its distal end stowed in a further compartment (not shown) carried by one of the external walls of the housing, such that liquid cannot pass from this compartment to the other compartments.
  • This further compartment is of narrow flute-form and can accommodate the handle without a cleaning head thereon.
  • the three main compartments contain replacement cleaning heads face-to-face in three vertical columns.
  • the wall of the housing 42 may be of a heavy-duty plastics sheet material.
  • the top 46 (which is shown partially cut away) may be removed permanently, or removed or displaced (eg by hinging) intermittently, at times when a cleaning head is needed.
  • Fig. 3B shows a refill pack of cleaning heads.
  • the refill pack is a housing like that of Fig. 3A, but is supplied without a handle, because the original handle 44 is retained.
  • the refill pack is of similar shape to the housing 42. Again, three main compartments are formed, again by means of three radial walls as described above.
  • the outer wall 48 of the refill unit 42 is of a flexible but strong plastics sheet material and its upper region may be torn away to allow access to the cleaning heads. To assist this process there is a band of perforations 50 extending around the wall, separating the upper region from the remainder of the wall and assisting the removal of the former.
  • the top of the narrow compartment for the handle can be seen as 49.
  • Figs. 4A-4H show alternative cleaning heads.
  • the cleaning head shown in Fig. 4A is of lozenge-form without a discrete protuberance, and is intended to be used by an embodiment of the type with reference to Figs. 1A-1C, having securement prongs, or with a handle having a rotatable auger-type head.
  • the cleaning head shown in Fig. 4B is also of lozenge-form but has a protuberance to enable it to be gripped in the manner described with reference to Figs. 2A-2C.
  • the cleaning heads shown in Figs. 4C-4H are all generally spherical, having rigid walls covered with fibrous and mildly abrasive materials. They have different frontal conformations to improve their scrubbing properties.
  • the cleaning head has a series of serpentine raised conformations.
  • the cleaning head has a series of hoops.
  • the cleaning head has a scalloped conformation.
  • the surface has a series of hoops which converge upon a nib (which may be pressed into tight corners during cleaning).
  • Fig. 4G shows a cleaning head which is also scalloped, but not in such a pronounced manner as in the cleaning head of Fig. 4E.
  • Fig. 4H shows a cleaning head with an array of parallel projections, providing a knobbly cleaning surface.
  • Figs. 5A and 5B show a housing in the form of an upright cylindrical container 50.
  • the container has an upper lid 51 and a lower opening 52 associated with a tray 54, the opening and the tray 54 being of size to admit only one ball-like cleaning head 56.
  • the tray has raised walls 57 which prevent the cleaning head from falling from the tray.
  • Within the container there is a wall 58 inclined at 45° to the horizontal, whose lower edge is coincident with the lower edge of the opening, and the inside edge of the tray.
  • On the outside of the container parallel to the cylinder axis there is a narrow chamber 60, to receive a handle of the type described above. In use the lid 50 is removed and the container filled with cleaning heads 52.
  • a single cleaning head is available on the tray 54, to be picked up by the handle (for example impaled by prongs or by an auger-type head). Once it has been picked up the next cleaning head passes through the opening onto the tray, ready for use. Once the cleaning article has been used the cleaning head is released and falls into the toilet bowl. The handle may be stowed in the chamber 60. When the next cleaning operation is needed it is removed and used to pick up the next cleaning head; and so on.
