Description

  • The present invention relates to cleaning apparatus, and methods. In particular, the present invention relates to cleaning apparatus and methods which are in certain preferred embodiments particularly suitable for cleaning lavatories, sanitary appliances as well as plumbing fixtures and other hard surfaces.
  • Brushes are notoriously old articles which are known to facilitate the cleaning of surfaces, and lavatories, sanitary appliances as well as plumbing fixtures may be effectively cleaned brushes. Alternatively, chemical cleaning compositions which typically include one or more active agents such as cleaning agent, disinfecting agent, fragrance agent, and/or an anti-lime scale agent or a mixture of two or more of such agents are also known to be useful. It is also known to use a combination of physical and chemical cleaning. Good results are expected when a chemical cleaning composition in used in conjunction with a brush, as the brush provides good abrasive contact with a soiled lavatory, sanitary appliance, plumbing fixture or for that matter any other surface particuarly hard surfaces, which abrasive contact typically loosens stains and soils on the surface(s) which can be more readily treated by the chemical cleaning composition. The art has suggested various articles of manufacture which suggest such a combination. For example, EP 123152A describes a system comprising a cartridge having a cleaning brush attached thereto, and wherein a cleaning fluid is discharged from a flexible bag through the cleaning brush. Further devices known to the art include those described in the following documents: GB 2342403; WO 01/45533; U.S. Pat. No. 5,984,555; U.S. Pat. No. 4,534,669; DE 2331694; DE 2040496; DE 1912606; GB 2342403; EP 1190644; DE 20101259; DE 29918902; DE 2331694; as well as DE 3104734.
  • Such combination cleaning device s however are typically poorly received by consumers as they typically suffer from a number of disadvantages which results in low consumer satisfaction which in turn limits their actual use. Such combination cleaning devices are often perceived to be ineffective in providing a desired cleaning and/or sanitizing effect. One particular shortcoming is in the messiness of using such devices, or the difficulty in dipsening a chemical cleaning compositions associated with such combination devcies. Such devices are typcially often unwieldy in use.
  • Broadly recited, it is amongst the objects of the present invention to provide a combination cleaning device useful in the cleaning of hard surfaces such as non-porous surfaces including glass, metals, ceramic surfaces, and the like as well as soft surfaces such as textiles, carpets, upholstery, garments and the like which combination cleaning device includes a body, and a cleaning head particularly an abrasive cleaning head such as a brush, abrasive pad or other physical abrasive means which is used to contact a surface requiring cleaning and/or disinfecting treatment, and which combination cleaning device further includes a chemical cleaning composition which may optinally also provide a sanitizing benefit, which combination cleaning device is manually graspable usually at the body thereof, by a user of the device. In paricularly preferred environments the chemical cleaning composition is provided in a vessel, which may be a non-pressurized, or alternately may be a pressurized or pressurizable vessel which is at least partially enclosed within the body of the combination cleaning device whererin the user of the device dispenses the cleaning composition which is expelled from the vessel and then to the cleaning means. Desirably the vessel includes an interlocking device mounted on said vessel or within the body of the combination cleaning device, or may be present on both the vessel and body, which must be properly engaged in order to permit dispensation of the cleaning composition from the vessel when the combination cleaning device is used.
  • Further objects of the invention include methods for treating a hard or soft surface in need of a cleaning and/or disinfecting treatment which method contemplates providing a combination cleaning device including a cleaning head and a chemical cleaning composition provided in a vessel, particularly a pressurized or pressurizable vessel, dispensing a quantity of the chemical cleaning composition to the cleaning means, and subsequently contacting the cleaning head with the surface in need of treatement.
  • Still further objects of the invention relate to methods for manufacturing a combination cleaning device as described herein.
  • According to a first aspect of the present invention there is provided a combination cleaning device in the form of a lavatory brush comprising a body which also functions as a handle graspable by a user of the device, and as a cleaning head, a brush head having a proximal end depending from the body and a distal end, the body having a cavity for accommodating a chemical cleaning composition and means for impelling chemical cleaning composition along a conduit from the body to the brush head, the brush head having bristles and having an outlet for chemical cleaning composition, proximate to the distal end thereof. By “proximate” when referring to the outlet(s), is to be understod that mean that the outlet is at the distal end of the brush, or in the region of the brush head near to the distal end of the brush. Preferably the brush head has only one outlet at the distal end outlet(s). According to one particularly preferred embodiment of the first aspect of the invention the outlet, or each outlet present in the brush head is arranged to issue cleaning composition without contacting the bristles of the brush head.
  • According to a second aspect of the present invention there is provided a combination cleaning device comprising a body which also functions as a handle graspable by a user of the device, and which contains a vessel containing a cleaning composition, means for impelling chemical cleaning composition along a conduit from the body to a cleaning head, wherein the cleaning head includes at least one outlet for the cleaning composition, and wherein the cleaning head may be permanently affixed to the body, or which may be removably affixed to the body or which may be interchanged by the user of the combination cleaning device. Said aspect of the invention contemplates for the subsitution of a variety of different cleaning heads which may be affixed to the body and each of which may be used to form a combination cleaning device. Each of the different cleaning heads desirably include a proximate end which may be removably attached to the body of the combination cleaning device either directly or by means of an intermediate linking member, as well as a conduit and at least one outlet for the chemical cleaning composition at the distal end of the cleaning head. Specific examples of cleaning head include: a brush head comprising one or more tufts of bristles, wherein said brush head and bristles may be formed according to any of a number of configurations; a cleaning head which includes a pad of an non-abrasive or abrasive material such as an abrasive pad; a cleaning head which includes a surface onto which may be removably affixed a woven or non-woven wipe or other generally planar sheet material which may provide an abrasive effect, which wipe or generally planar sheet material may be a single-use wipe or which may be used a number of times before being removed and discarded. The cleaning head may include any combination of such materials as recited above. The various forms of cleaning heads may have one or more outlets at a distal end thereof which permits for the egress of the cleaning composition from the cleaning head. In certain preferred embodiments the cleaning head has a plurality of outlets. According to other preferred embodiments the cleaning head comprises a single outlet at the distal end thereof.
  • A third aspect of the present invention provides a combination cleaning device comprising a body adapted for containing a vessel containing a quantity of a cleaning composition, said body which also functions as a handle graspable by a user of the device, and a cleaning head wherein the cleaning head may be permanently affixed, or which may be removably affixed to the body and which may be interchanged by the user of the combination cleaning device, said combination cleaning device which further comprises mounted on said vessel or within said body, or parts of which may be present on both the vessel and body, which interlocking device must be properly engaged in order to permit egress of the cleaning composition from the vessel when the combination cleaning device is used.
  • In any of the aspects of the invention, preferably the cleaning composition is contained in vessel, e.g., a canister within the body of the combination cleaning device, and most preferably the vessel is removable from within the body and is replaceable within the body.
  • In any of the aspects of the invention, the vessel need not be totally obscured from view when inserted within the body, rather it may be partially visible when installed within the body of the combination device taught herein. For example, a portion of the body may be omitted, so to form a viewing window which would permit the user to view at least a part of the vessel when the vessel is installed in the body. Such would be particuarly convenient wherein it would be advatageous for the consumer to view a label or other identifying marking(s) on the vessel when the combination device is assembled and ready for use as described hereinafter.
  • The vessel according to the invention includes a closure or other form of valve which may be used to limit the egress of cleaning composition from the vessel. According to certain embodiments the vessel is vented by a one-way valve. Preferably the one-way valve is located within the body of the combination cleaning device. Preferably, this one-way valve is located such that it does not become submerged during use of the combination cleaning device. In certain embodiments, the vessel is preferably vented to allow for the ingress of air as cleaning composition is impelled from the combination cleaning device. Alternately and preferably the vessel may be pressurized, such that fluid exiting the vessel cannot be retracted into the vessel once it it dispensed.
  • The cleaning composition necessarily is impelled from the vessel in order to dispense the cleaning composition through the cleaning head in the device according to the invention. A variety of means, and techniques may be used to effectively dispense the cleaning composition from the vessel.
  • Desirably, the means for impelling are operable by one hand. Preferably, the means for impelling are operable by a hand which is grasping and supporting the body of the combination cleaning device. Preferably, the means for impelling are operable by the (human) hand and/or is actuated by the (human) hand which is grasping and supporting the body of the combination cleaning device without adjustment of the position of said hand on the combination cleaning device.
  • One means for impelling the cleaning composition contemplates the use of an electrical motor which is contained in the body of the combination cleaning device, which motor is actuated by an electrical contact or electrical switch which, when engaged closes a circuit which transmits electrical current from a battery/battery which operates the motor. The motor engages one or more suitable mechanical elements which, when driven by the motor, cause the cleaning composition to be impelled from the inventive device. Any suitable mechanical elements may be used to achieve this effect and such mechanical elements. By way of non-limiting example suitable mechanical elements include one or more of the following combinations of mechanical elements:
      • (a) a gear mounted on the shaft of the electrical motor engages a piston connected to a piston rod, said piston rod having a rack of mating gear teeth which engage the gear mounted on the motor shaft, such that when the motor is engaged the piston is urged against the vessel contained in the body which impels the release of the cleaning composition;
      • (b) a threaded gear on the shaft of, or a threaded shaft of the electrical motor engages a piston connected to a piston rod, wherein the piston rod including a threaded portion which engages the threaded gear/threaded shaft of the motor, such that when the motor is engaged the piston is urged against the vessel contained in the body which impels the release of the cleaning composition;
      • (c) a rotatable lobed cam or rotatable wheel eccentrically mounted on the shaft of the electrical motor, such that when the motor is actuated, the rotating lobed cam or wheel is urged against the vessel contained in the body which impels the release of the cleaning composition;
      • (d) a rotatable lobed cam or rotatable eccentric wheel is mounted on the shaft of the electrical motor, which is used in conjuncation with a mechanically opearable pump having a pump-arm (trigger) such that when the motor is actuated, the rotating lobed cam or wheel is urged against the pump-arm of the mechanically operable pump which operation impels the release of the cleaning composition;
  • Of the aforesaid combinations of mechanical elements with electrical motors, those described in (a) and (b) in certain embodiments (c) are particularly useful when the vessel is an aerosol canister or other pressurized vessel, while those described in (d) and in certain embodiments of (c) are particulary useful with non-pressurized vessels.
  • The electrical motor may be any which is suitable to provide sufficient force, however low voltage electrical motors which may be operated from a battery source are conveniently and advantageously used. The battery source may be single-use non-rechargeable batteries, or may be rechargeable batteries, including appropriately sized lithium ion, and nickel cadium based batteries. While the use of batteries are preferred as such pemits for the convenient and mobile use of the combination cleaning device, it is contemplated that the motor may also be powered by connection to a non-portable power source, e.g., a suitable transformer attached to the electrical mains of a building.
  • A further means for impelling the cleaning composition contemplates the use of an electrical solenoid which is contained in the body of the combination cleaning device, which solenoid is actuated by an electrical contact or electrical switch which, when engaged closes a circuit which transmits electrical current from a battery/battery which operates the solenoid. The plunger of the solenid may conveniently engage one or more suitable mechanical elements which, when driven by the solenoid, cause the cleaning composition to be impelled from the inventive device. Alternately the plunger of the solenid may engage a portion of a vessel, particularly a aerosol canister or other pressurized vessel and urge it towards the distal end of the body of the combination cleaning device, and impel the cleaning composition from the vessel. Such a solenoid may be any which is found to be effective, but is desirably one which may be operated using a low voltage source, such as may be provided by batteries or a transformer such as described above with reference to the use of an electrical motor.
  • A still further means for impelling the cleaning composition contemplates the use of an electrically operated pump which is contained in the body of the combination cleaning device, which pump is actuated by an electrical contact or electrical switch which, when engaged closes a circuit which transmits electrical current from a battery/battery which operates the pump. Such means is particularly adapted for use in dispensing cleaning composition from a non-pressurized vessel.
  • A further means for impelling the cleaning composition which does not require a motor or electrical current contemplates the use of an engageable shaft connected at one end thereof to a piston, and a manually operable trigger which, when operated interacts with the engageable shaft to advance it in linear direction. An embodiment of such means may be, e.g., a flexible shaft having a rack of teeth, and an engagement gear or engagement pawl associated with the trigger of the combination cleaning device. In operation, depressing the trigger enages the engaement gear, or pawl with one or more of the teeth of the shaft, causing the rack attached at one end to a piston forward. This motive force may be used to expel a cleaning composition from any of a variety of vessels which may be used with the present invention, particulary with non-pressurized vessels such as bellows bottles, or other collapsible or manually deformable vessels.
  • One preferred means for impelling the cleaning composition comprises the use of a manually-operable pump, wherein the pump is operable by the user. Desriably such a manually operable pump only permits for the egress of chemical cleaning composition from the vessel when it is operated or otherwise actuated.
  • An alternate preferred means for impelling the cleaning composition comprises the use of a vessel which is manually deformable. The user utilizing the combinantion device, via pressure such as squeezing pressure exerted by the user, cases the deformation of the vessel which impels the egress of the cleaning composition containined within the vessel.
  • A still further alternate preferred means for impelling the cleaning composition comprises the use of a deformable vessel which however is deformed by means other than that directly exerted by a user, for example, a pressurized or pressurizable vessel which has a non-deformable exterior such as a metal canister, said vessel which contains a first plenum or a deformable bag containing the cleaning composition, and a second plenum which may be the intermediate volume between the first plenum and remaining interior volume of the vessel. In such a preferred embodiment it is contemplated that pressurization of, or an increase in the volume of the second plenum causes a reduction in the volume of the first plenum which causes the egress of the cleaning composition from the vessel.
  • An alternate preferred means for impelling the cleaning composition comprises the use of a vessel which contains two or more separate chemical cleaning compositions which are contained in a vessel (or plurality of vessels) which contain the two or more chemical cleaning compositions separate from one another until the said chemical cleaning compositions are expelled from the vessel wherein they may intermix. Such may be particularly advantageous wherein the cleaning composition is stably stored and contained in two or more separate plenums within a vessel, or in two or more separate vessels but when mixed form an active cleaning and/or disinfecting composition. One example of such a cleaning composition having such properties are two-part compositions containing a bleach constitutent in one of said two parts, and a bleach activiator constituent in the other of said two parts which, when intermixed, form a highly effective bleach composition which may have both cleaning efficacy and/or sanitizing efficacy.
  • A particularly preferred and effective example of a vessel which may be used in the combination cleaning device according to the invention is a pressurized aerosol canister which comprises a pressurizable canister, and a manually actuated valve which, when actuated, releases its contents under pressure.
  • A further effective example of a vessel which may be used in the combination cleaning device is a known as an “Atmos” vessel, which may be generally described as comprising a flexible inner bladder adapted to contain a quantity of a material, such as the cleaning composition according to the invention, which inner bladder is contained within an elastomeric sleeve. The inner bladder may be filled and used to contain the cleaning composition wherein it is maintained in a pressurized state due to the mechanical compressive force of the inner bladder, but primarily due to the mechanical compressive force of the elastomeric sleeve. The Atmos vessel further comprises a valve or other outlet or valve which can be acutated in order to permit the egress of its contents under pressure.
  • A still further effective form of a vessel which may be used in the combination cleaning device is a bellows bottle. Such bellows bottles may be generally described as a collapsible vessel which may be compressed, typically substantially only in one direction, usually in the vertical direction. Typically a series of preformed pleats or ribs are formed in the bellows bottle such that when it is compressed, the wall(s) of the bellows bottle folds in the direction of the pleats or ribs, and simultaneously the interior volume of the bellows bottle is diminished. Typically, when used in the combination cleaning device taught herein the cleaning composition may be maintained in an unpressurized state, as pressurization of the contents of the bellows bottle occurs when the bellows bottle is compressed and its interior volume diminished. Of course, a a valve or other outlet or valve which can be acutated is typically present with the bellows bottle in order to permit the egress of its contents under pressure.
  • Other forms of vessels which may be used with the combination cleaning device are described with reference to the Figures. It is to be understood varous forms of vessels may be used with different configurations of the combination cleaning device and thus satisfy the objectives of the present invention.
  • Most preferably, the means for impelling are manually operated. Preferably, the means for impelling are actuated by a user's own force.
  • According to a yet further aspect of the invention there is provided a method for cleaning surface such as hard surface or a soft surface, which method comprises the steps of:
      • (a) providing a combination cleaning as described herein wherein said device includes a vessel contining a cleaning composition; (b) impelling the cleaning composition to exit from the vessel, and pass through the body to one or more outlets at the brush head, through the outlet proximate to the distal end of the brush head and directing chemical cleaning composition passing through the outlet onto a surface to be cleaned; and (c) using the bristle brush, head in combination with the chemical cleaning composition to clean the surface, to be cleaned.

  • Referring now to FIGS. 1 to 7 therein is shown an embodiment of the combination cleaning device according to the invention in the form of a lavatory brush 100 comprising a bristle brush head 10 and a handle 20. The bristle brush head 10 exemplifies one form of a cleaning head according to the invention, while the handle 20 exemplfies one form of a body according to the invention. The bristle brush head 10 comprises a proximal end 12, a distal end 14, bristles 16 and an outlet 18. The handle 20 comprises a neck 22, a body 24, a lid 26 and a trigger 28. The neck 22 and body 24 of the handle 20 are formed from two conjoined sections; a front section 30 and a rear section 32. The proximal end 12 of the bristle brush head 10 is attached to a distal end′ of the neck 22. The lid 26 is movable between a first position in 20 which it closes an aperture defined by a proximal end of the body 24 of the handle 20 and a second position in which the aperture is unobstructed. The lid 26 is hinged to move from the first position to the second position by hinge means (not shown). The lid 26 is secured in the first position by an interference fit joint. A recess 23 is provided in the body 24 of the handle 20 to assist the user in moving the lid 26 from the first position to the second position.
  • The body 24 of the handle 20 is shaped to allow it to be easily grasped by a user. The body 24 of the handle 20 is also shaped to allow it to contain a canister 34 of chemical cleaning composition. The canister 34 exemplifies a vessel according to the invention. The canister 34 is manufactured from a transparent plastics material, although it may also be produced from an opaque material such as a metal.
  • A proximal end of the canister 34 comprises a vent 36. The vent 36 comprises a one way valve allowing air to pass from the atmosphere into the canister 34 when the air space within the canister 34 is increased, during operation. Neither air nor chemical cleaning composition from within the canister 34 can pass through the vent 36 to exit the canister 34.
  • A distal end of the canister 34 comprises a pump 38. The pump 38 can be actuated to draw chemical cleaning composition from within the canister 34. Actuation of the pump 38 reduces the pressure within the canister 34 drawing air from the atmosphere through the vent 36 into the canister 34. When the pump 38 is not being actuated no chemical cleaning composition can exit the canister 34. The pump 38 may be formed of an assemble of discrete components which cooperate to provide a pumping effect when operated.
  • Within the lavatory brush 100 is contained a trigger mechanism 36 and a conduit 42, which in this embodiment is a passage generally concentric with the neck 22 and with the bristle brush head 10 and which passes therethrough where it terminates at an orifice, or opening at the distal end of the bristle brush head 10. The trigger mechanism 40 cooperates with the trigger 28 to allow a user to impel chemical cleaning composition contained within the canister 34 along a conduit 42 to exit the bristle brush head 10 through the opening 18 at the distal end 14. Preferably the chemical cleaning composition exiting the opening 18 does so without contacting the bristles. Desirably, the cleaning composition exits the combination cleaning device as a jet able to impinge upon a lavatory surface, particularly a toilet bowl surface.
  • In use, a vessel, or canister 34 containing a cleaning composition is inserted into the handle 20 through the aperture defined by a proximal end of the body 24 of the handle 20 when the aperture is unobstructed by the lid 26. The lid 26, is then replaced to, improve the aesthetic appeal of the lavatory brush 100, to prevent dirt from entering the handle 20 and to retain the canister 34 in place. The pump 38 located within the handle 30, communicating with the conduit 42 and the trigger mechanism 40. A user grasps the body 24 of the handle 20 and can conveniently use an index finger to actuate the trigger 28. Symmetry of the illustrated device facilitates use by left and right-handed users. Actuation of the trigger 28 transmits force through the trigger mechanism 14 to the pump 38. Upon actuation, the pump, 38 impels chemical cleaning composition from within the canister 34 into the conduit 42. Further actuation of the pump 38 impels chemical cleaning composition along the conduit 42 and through the opening 18 and the distal end of the bristle brush head 10.
  • A transparent portion 33 of the rear section 32 allows the level of chemical cleaning composition within the canister 34 to be easily observed by the user, although not all embodiments of the combinaton cleaning device include a transparent portion in the body of the combination cleaning device.
  • The user may operate the combination cleaning device according to any of a number of cleaning methods made possible by the use of the lavatory brush 100. The user can spread a layer of chemical cleaning composition from the lavatory brush 100 over surfaces to be cleaned by first actuating the trigger 28 before contacing the treated surface with the bristles 16 of the bristle brush head 10. Alternatively, the user can simultaneously brush and apply chemical cleaning composition to a surface being treated. Of course, the combination cleaning device can be used without chemical cleaning composition if desired. The location of the outlet 18 proximate the distal end 14 of the bristle brush head 10 allows the user to accurately judge the amount of chemical cleaning composition dispensed. Also, the user can accurately direct the chemical cleaning composition to 5 where it is required. The positioning of the outlet 18 also usuallly helps to maintain the bristles 16 free from a build-up of unused chemical cleaning composition.
  • The pump 38 is preferably designed to avoid sucking any chemical cleaning composition, air or other fluid back into the canister 34. However, to further reduce this possibility a one-way valve (not shown) may be located in the conduit 42 immediately within the outlet 18. As the vent 36 is situated within the body 24 of the handle, it is unlikely to become submerged or exposed to other fluids. The vent 36 will therefore in use allow only air to pass through it and enter the canister 34.
  • As the pump 36 only dispenses chemical cleaning composition when it is being actuated by a user, the canister 34 can be swapped for one containing an alternative chemical cleaning composition without dripping or making other undesirable mess. Similarly, a canister 34 that is all but empty will not drip or leak when removed for replacement.
  • FIG. 7 shows the lavatory brush 100 in combination with a stand 200. The stand 200 engages the lavatory brush 100 at an interface region between the neck 22 and the body 24 of the handle 20. The stand 200 allows the lavatory brush 100 to be conveniently and hygienically stored.
  • Referring now to FIGS. 8 to 10 there is shown a further combination cleaning device according to the present invention, again in the form of a lavatory brush 101. Lavatory brush 101 comprises a different canister 35 than the canister 34 of FIGS. 1 to 7, and includes a number of other differences in order to accommodate 5 the canister 35. Where meaningful, like reference numerals have been used for corresponding features between FIGS. 1 to 7 and FIGS. 8 to 10.
  • The handle 20, exemplifying a “body” according to the invention comprises an elongate section of a 10 plastics material attached to the proximal end 12 of the bristle brush head 10 through a collar 21. The bristle brush head 10 exemplifies a further embodiment of a “cleaning head” according to the present invention. A proximal end 23 of the handle 20 comprises a pair of resilient projections 25 separated by a recess 27.
  • The canister 35 comprises a resilient envelope having a pair of diametrically opposed projections 37 extending from an upper region of its exterior surface. The canister 35 comprises a blow moulded thermoplastics envelope. The canister 35 locates within the handle 20 and is held in place by a snap fit joint formed by engagement of the projections 37 with the recess 27. The canister 35 exemplifies an alternate form of a “vessel” according to the present invention.
  • To impel chemical cleaning composition from the canister 35 the user exerts manual pressure and squeezes the upper region of the canister 35. The user 25 may further manually squeeze the resilient projections 25 to compress the canister 35 therebetween. The canister 35 is a manually deformable vessel.
  • With attention now to FIG. 8 may be seen a an embodiment of a simple one-way valve which comprises a check-ball 18A located in the path of the conduit and adjacent to the outlet 18. As the vessel 35 is resilient, and dispenses chemical cleaning composition only when it is deformed by manual squeezing, the check-ball 18A permits only for the egress of chemcial cleaning composition from the combination cleaning device, and not for the ingress of chemical cleaning composition into the canister 35 of he device. Indeed such a check-ball 18A or a similar check ball may be incorporated into any embodiment of the invention, and provide a useful anti-retraction feature in ensuring that fluid is not sucked back into the combination cleaning device described herein.
  • Referring now to FIGS. 11 to 13 there is shown still further embodiment of the combination cleaning device of the invention, again in the form of a lavatory brush 102. The lavatory brush 102 is adapted to receive a canister 35A in the form of a deformable tube. The canister 35A is at least partially located within the handle 20 and is held in place by engagement with the lid 26. The lid 26 comprises a distal projection having an aperture 27A defined therein. The aperture 27A engages with a projection 37A extending from an upper region of the interior surface of the handle 20. The lid 26 is held in place by a snap-fit joint formed by engagement of the projection 37A with the aperture 27A. In this embodiment the handle 20 exemplfies a body, the bristle brush head 10 exemplifies a cleaning head and the canister 35A exemplifies a vessel, particularly a manually deformable vessel according to the present invention.
  • To impel chemical cleaning composition from the canister 35A the user manually squeezes and deforms the upper region of the canister 35A through an open section of the handle 20 as can be seen in FIG. 13.
  • Referring now to FIGS. 14 to 16 there is shown a still further embodiment of a combination cleaning device according to the invention, again in the form of a lavatory brush 103. The handle 20 of the lavatory brush 103 is similar to that of the lavatory brush 101 of FIGS. 8 to 10, and handle 20 again exemplifies a body of the combination cleaning device according to the invention. The handle 20 of the lavatory brush 103 comprises a pair of resilient projections 25B separated by a recess 27B. The recess 27B is occupied by resiliently flexible membrane. The membrane prevents dirt from accumulating in the recess 27B and also prevents a user's hand from becoming trapped between the projections 25B. The lavatory brush 103 also comprises a canister 35B which exemplifies a vessel according to the invention, as well as a cleaing head, exemplfied by the bristle brush head 10 illlustrated in FIGS. 14-16.
  • Referring now to FIG. 17, there is shown one preferred combination cleaning device according to the invention, again in the form of a lavatory brush 300 comprising a brush head 320 and a body 310, adapted to contain a vessel which contains a chemcial cleaning composition. The brush head 320 exemplfies a further example of a cleaning head according to the invention, and the body 30 exemplifies a body of a combination cleaning device according to the invention. Brush head 320 comprises a proximal end 322, a distal end 324, bristles 326 and an outlet 328, and includes within a conduit 372 for conducting the cleaning composition which exits from the vessel when the lavatory brush 300 is used. The body 310 comprises a handle portion 302, having a proximal end 302A and a distal end 302B, as well as a body portion 312, having a proximal end 312A and a distal end 312B, a handle portion 302 and a body portion 312 being held together with ring 316. Ring 316 is connected to handle portion 302 at distal end 302B. Body 310 is formed by connecting distal end 302B of handle portion 302 to proximal end 312A of body portion 312 by interconnecting these parts and by use of engaging button 318. There are two engaging buttons (one opposite button 318 and not shown) but only one button 318 is sufficient To open brush 300, engaging button(s) 318 is (are)pushed and handle portion 302 can be removed, allowing access to the inner cavity of body portion 312. Then, an appropriate can 351 (as per FIG. 18) containing a chemical cleaning composition can be removed, when empty, and replaced with an appropriate replacement can. Can 351 exemplifies one form of a vessel according to the present invention.
  • Proximal end 302A of handle portion 302 further comprises a safety lock switch 330 and an actuating switch 332. Safety lock switch 330 and actuating switch are interconnected 10 (as shown in FIG. 18) so as to provide a child safety locking system to prevent accidental discharge of the chemical cleaning composition. Such a safety lock switch and cooperating actuating lock switch may be included in any embodiment of the invention, and desirably are present in any embodiment of the invention, especially where the vessel containing the chemical cleaning composition is a pressurized vessel such as an aerosol canister.
  • Proximal end 322 of brush head 320 is attached to distal end 312B of body portion 312. As shown in FIG. 18, there is fluid communcation through the brush head 320 at outlet 328 via a conduit (not shown.)
  • FIG. 18 shows a cross-section of brush 300 shown in FIG. 17 along section line A-A. Safety lock switch 330 is connected by spring 334, which is placed within spring holder 350, to actuating switch 332. When safety lock switch 330 is depressed, actuating switch 332 will be able to move, causing spring 334 to move together with spring holder 350. When spring holder 350 moves, face 354 (of spring holder 350) pushes against bottom rim 352 of can 351 (which can be, among others, either a traditional aerosol can where propellant and liquid are intermixed or be a system where the liquid is placed within a bag (plenum) which is then placed within a can and the area between the outer wall of the bag and the inner wall of the can (second plenum) is pressurized with a propellant (the so-called “bag-in-can” or “barrier pack” aerosol package). The bag is then pressurized but no propellant is expelled. Examples such cans are found in U.S. Pat. Nos. 3,022,923; 3,109,463; 3,756,476; 3,788,521; 3,896,970; 3,929,132; 4,067,499; and 6,439,430). At the end opposite bottom rim 352 is mounting cup 358, which carries a valve assembly (whose construction is well known in the art) having valve 356, and can overcap 360 and actuator 364. Overcap 360 rests upon nib 375 which is molded into distal end 312B. Valve 356 is connected to opening 372 through opening 370 (which is mounted within adapter 362) such that it permits a liquid or aerosol foam to be discharged out of outlet 328. Adapter 362 can be molded into distal end 312B or can be a separate piece which fits within an appropriate opening within distal end 312B. Those in the art will recognize that valve 356 could be connected to one long tube that could extend from the can 351 all the way through the distal end of body portion 312B and through opening 372 until just rearward of the opening of outlet 328. When switches 330 and 332 are engaged, moving spring 334 and spring holder 350 against bottom rim 352 of can 351 as described above, can 351 will be urged forward and towards the distal end 312B of body portion 312. Such displacement of the can 351 causes actuator 364 to engage with overcap 360, causing valve 356 to open, thereby allowing liquid or aerosol to flow through the aforementioned openings and/or tubes and ultimately out of opening 328. When switches 330 and 332 are disengaged and returned to their original position, can 351 returns to its original position and actuator 364 disengages with overcap 360, causing valve 356 to close, and the egress of cleaning composition from the can 351 to cease.

  • FIG. 20 shows a further embodiment of a combination cleaning device 400 according to the present invention. The combination cleaning device 400 comprises a brush head 405 and a body 410, adapted to contain a vessel which contains a chemical cleaning composition (not visible). The brush head 405 exemplfies a further example of a cleaning head according to the invention, and the body 410 exemplifies a body of a combination cleaning device according to the invention. Brush head 405 comprises a proximal end 422, a distal end 424, bristles 426 and an outlet 428, and includes within a conduit (not visible) for conducting the cleaning composition which exits from the vessel when the lavatory brush 400 is used. The conduit extends through the core 430 from which the bristles 426 extend outward radially from the surface of core 430. The body 410 comprises a handle portion 440, having a proximal end 442 and a distal end 444, as well as a body portion 450, having a proximal end 452 and a distal end 454, the handle portion 440 and a body portion 450 being held together with ring 460. Ring 460 is connected to handle portion 440 at distal end 442. Body 410 is formed by connecting distal end 442 of handle portion 440 to proximal end 452 of body portion 450 by interconnecting these parts and by use of engaging button 454. In use, the distal end 444 forms a graspable handle which may be manually gripped. To open the body 410, engaging button 454 is pushed and handle portion 440 can be removed, allowing access to the inner cavity of body portion 410. Then, an appropriate vessel, such as a pressurized can (not shown) containing a chemical cleaning composition can be removed, when empty, and replaced with an appropriate replacement can.
  • Desirably handle portion 440 further comprises a safety lock switch 456 and an actuating switch 458. Safety lock switch 456 and actuating switch 458 are interconnected (as shown in FIG. 18) so as to provide a child safety locking system to prevent accidental discharge of the chemical cleaning composition; such may be included in any embodiment of the invention.
  • The proximal end 422 of the brush head 405 is attached to distal end 454 of body portion 450. While not shown in FIG. 20, it is to be understood that the emboidmnt shown includes a fluid conduit providing fluid communication through the brush head 405 with an egress at outlet 428.
  • FIG. 21 illustrates an embodiment of an interlocking device adapted to be mounted upon a vessel according to the present invention. In the embodiment shown in FIG. 21, the interlocking device 500 comprises a plate 502 having a generally circular downwardly depending skirt 504, and one or more spring legs 506 upwardly depending from the plate 502. Here while 4 spring lets 506 are depicted only one, but preferably at least two are present. Advantageously the plate 502 and the downwardly depending skirt 504 are advantageously generally circular and concentric, with the inner diameter of the downwardly depending skirt 504 sized to encompass a circumferential ring 507 which is commonly found surrounding most conventional aerosol valves and valve stems. While not visible in FIG. 21, but visible in FIG. 22 in interior of the downwardly depending skirt 504 and near the lower margin 508 thereof are desirably present one or more frangible tab elements 510 which may be used to provide a “snap-fit” upon the circumferential ring 507 but when the interlocking device 500 is removed therefrom the one or more tab elements 510 break thus dissuading or disabling the use of the interlocking device 500 on a further vessel. The plate 502 necessarily includes at least a central orifice 512 which is positioned to be above the valve stem 514 (not shown in FIG. 21) which may be circular, or which may include flexible wings 516 extending towards the center of the central orifice 512 and providing a barrier for inadvertant contact by a consumer with the valve stem 514 and thereby ensuring the the contents of the pressurized canister 518 is not inadvertandly released. The plate optionally but in most instance desrably further includes one or more keyway aperture(s) 520 each of which extends through the plate 502 and which defines a passage therethrough. As seen in FIG. 21, two keyway aperture(s) 520 are depicted, each having an arcuate geometry. The operation of the interlocking device 500 will be more clearly described with reference to FIG. 22.
  • FIG. 22 illustrates in a cross-sectional view the arrangment of the interlocking device 500 according to FIG. 21 mounted on an aerosol canister 518, and installed and engaged within the body 530 of a combination cleaning device according to the invention. While only a portion of the body 530 is illustrated, and similarly while only a portion of the aerosol canister 518 contaning a pressurized cleaning composition is shown, the principles of this inventive embodiment will nonetheless be sufficiently described. The embodiment of the combination cleaning device illustrated on FIG. 22 also depicts a bristled brush head 540 as the cleaning head according to the invention.
  • When the vessel, viz., aerosol canister 518 having mounted thereon the interlocking device 500 is inserted into the interior cavity 550 of the body 530, it is moved towards the distal interior end 552 thereof and may be rotated so that the one or more keyway aperture(s) 520 present in the plate 502 are aligned to admit corresponding keypins 532 which pass into, and prefeably through the plate 502 via the keyway aperture(s) 520. The keypins 532 extend from the sloping inner distal wall 554 of the body 530 towads the proximal end of the body 530. The length of each of the keypins 532 is desirably sufficently long to pass into, or through its corresponding keyway aperture 520 yet not physicaly interfere with the actuation of the valve 514. Similarly the cross-sectional geometries of each of the keypins 532 should correspond to the cross-sectional geometries of its corresponding keyway aperture 520. It is contemplated that unlike the embodiment illustrated in FIG. 21, that the keyway apertures 520 may have different cross-sectional geometries which are dissimilar. Notwithstanding the foregoing, it is to be understood that while the use of keyway aperture(s) 520 and corresponding keypins 532 provide specific advantages, they are not necessary to the successful practice of the invention, although their presence represents a particularly preferred embodiment thereof.
  • When the vessel, viz., aerosol canister 518 having mounted thereon the interlocking device 500 is inserted into the interior cavity 550 of the body 530, the spring legs 506 extend from the plate 502 and towards the sloping inner distal wall 554 of the body 530. At the same time, nipple 556 extending inwardly from the distal interior end 552 of the body 530 engages, or is in near proximity to the valve 514 of the aerosol canister 518 via the central orifice 520. When flexible wings 516 are present, such are sufficiently flexible so as to not interfere with the egress of the chemical cleaning composition from the pressurized aerosol canister 518 when the valve 512 is actuated. The flexible wings 516 may be omitted in accordance with certain preferred embodiments, in which case the only a central orifice 520 would be present.
  • In use, the operation of a user of the combination cleaning device urges the aerosol canister 518 to move towards the distal interior end 552 of the body 530, causing the spring legs 506 to contact the sloping inner distal wall 554 of the body 530, and to also cause the valve 512 to engage the nipple 556 which engagement causes the egress of the chemical cleaning composition from the interior of the aerosol canister 518 outwardly through the valve 512 and into the fluid conduit 558 where, due to its elevated pressure, it passes into the fluid conduit 560 of the cleaning head where it is expelled from the combination device via the orifice 562. When the user ceases to urge the aerosol canister 518 to move towards the distal interior end 552 of the body 530, the spring legs 506 relax and urge the aerosol caniser 518 to retract away from the the sloping inner distal wall 554 of the body 530, and in the direction of the proximal end of the body (not shown.)
  • It is to be understood that any action by the user to cause displacement of the aerosol canister 518 with respect to the the sloping inner distal wall 554 of the body 530 which is sufficient to trigger the egress of the chemcial cleaning composition is sufficient, and that such displacement may be caused directly by the user or by intermediate mechanical means, or by electrically opearated means such as motors or solenoids as described above. In certain preferred embodiments the interlock device described with reference to FIG. 21, 22 may be incorporated into the embodiments of the combination cleaning devices according to the embodiments illustrated on any of FIGS. 17-20.
  • It is also to be understood that while the interlock device and its operation is described with reference to FIG. 21, 22 is discussed using a pressurized canister, that it is clearly contemplated that any form of vessel, pressurized or non-pressurized, deformable or non-deformably as described in this specification may advantageouly incorporate such an interlock device.
  • FIG. 23 illustrates an alternative embodiment of an interlock device 600 adapted to be mounted upon a vessel, here a pressurized vessel in the form of a conventional aerosol canister 605 according to the present invention. The interlocking device includes a generally cylindrical body 610 which is suitably dimensoned so to encompass a circumferential ring 607 which is commonly found surrounding most conventional aerosol valves and valve stems. While not visible in FIG. 23, but visible in FIG. 24 within the interior of the cylindrical body 610 and near the lower margin 608 thereof are desirably present one or more frangible tab elements 610 which may be used to provide a “snap-fit” upon the circumferential ring 607 but when the interlocking device 600 is removed therefrom the one or more tab elements 610 break thus dissuading or disabling the use of the interlocking device 600 on a further vessel. The interlock device 600 also includes a plurality of spring legs 612 extending upwardly from the cylindrical body 610 and each terminating at an end 614. A center nipple 616 having a fluid conduit 618 passing therethrough, the center nipple 616 having a valve stem end 620 and at the opposite end thereof, a top end 622. Each of the spring legs 612 includes a diagonal stay 624 which interconects each spring leg 612 with the center nipple 616 at or in the region of the valve stem end 620 such that when the end(s) 614 of one or more of the spring legs 612 is displaced or flexed in the direction of the center nipple 616, the diagonal stay 624 urges the valve stem end 620 downwardly in the direction of the lower margin 608 of the cylindrical body 610. In use, the elements of the interlock device 600 are desirably sized or dimensioned so that there is close fit or a small distance between the valve stem end 620 and the valve stem of the aerosol canister.
  • The operation of the interlock device 600 is described in more detail in conjuntion with FIG. 24. FIG. 24 illustrates in a cross-sectional view the arrangment of the alternative interlocking device 600 according to FIG. 23 mounted on an aerosol canister 605, and engaged within the body 630 of a combination cleaning device according to the invention. As is seen from FIG. 24, the interlock device 600 is engaged by a “snap-fit” upon the periphery of the circumferential ring 607 found surrounding the aerosol valves and valve stem 640. While only a portion of the body 630 is illustrated, and similarly while only a portion of the aerosol canister 605 contaning a pressurized chemical cleaning composition is shown, the principles of this inventive embodiment will nonetheless be sufficiently understood. The embodiment of the combination cleaning device illustrated on FIG. 24 also depicts in a pad head 690 as an cleaning head according to the invention. When the vessel, viz., aerosol canister 605 having mounted thereon the interlock device 600 is inserted into the interior cavity 632 of the body 630, the spring legs 612 extend towards the sloping inner distal wall 636 of the body 630. At the same time, conduit nipple 638 extending inwardly from the distal interior end 634 of the body 630 engages, or is in near proximity to the top end 622 of the center nipple 616.
  • In operation, the user of the combination cleaning device urges the aerosol canister 605 to move towards the distal interior end 634 of the body 630, causing the spring legs 612 to contact the sloping inner distal wall 636 of the body 630. Such flexes the spring legs 612 inwardly in the direction of the center nipple 616 which is moved downwardly by the action of the diagonal stays 624 which causes the valve stem end 620 to contact the valve stem 640, causing the release of the pressurized chemical cleaning composition out from the interior of the pressurized vessel 605, whereby it exits from the pressurized vessel via the fluid conduit 618, and thereafter through the cleaning head 690 via conduit 692. When the user ceases to urge the aerosol canister 605 to move towards the distal interior end 634 of the body 630, the spring legs 612 relax and urge the aerosol canister 605 to retract away from the the sloping inner distal wall 636 of the body 630, and in the direction of the proximal end of the body (not shown.)
  • Similarly noted with regard to the embodiment illustrated on FIG. 21, 22 that with reference to the embodiment shown on FIGS. 23, 24 that it is to be understood that any action by the user to cause displacement of the aerosol canister 605 which is sufficient to trigger the egress of the chemical cleaning composition is sufficient, and that such displacement may be caused directly by the user or by intermediate mechanical means. In certain preferred embodiments the interlock device described with reference to FIG. 23, 24 may be incorporated into the embodiments of the combination cleaning devices according to the embodiments illustrated on any of FIGS. 17-20. It is also to be understood that while the interlock device and its operation is described with reference to FIG. 23, 24 is discussed using a pressurized canister, that it is clearly contemplated that any form of vessel, pressurized or non-pressurized, deformable or non-deformably as described in this specification may advantageouly incorporate such an interlock device.
  • With respect now to FIG. 25, therein is depicted a cleaning head 700 having a neck portion 702 and a pad portion 704. The neck portion 702 includes a threaded recess 706 which includes mating threads which are adapted to receive corresonding threads present on body (not shown) used to form a combination cleaning device. A fluid conduit 708, depicted in dotted lines extends from the interior of the neck portion 702 where it terminates at a face 710 in an outlet 712 present on the underside of pad portion 704. A similar cleaning head 700 is intended to be represented in FIG. 24 (as 690). The cleaning head 700 also includes a cleaning pad 714 which may be permanently affixed to, or which may be removably affixed to the cleaning head 700. Conveniently the cleaning pad 714 is affixed to the face 710 by any suitable means. The pad may be of a non-abrasive or abrasive material, or alternately may be a wipe, such as a woven or non-woven wipe or may be generally any other planar sheet material which may provide an abrasive effect and/or a wiping effect. Alternately the pad may be an absorbent foam material, such as a porous sponge, especially a porous flexible sponge which may optionally include an abrasive material affixed to the sponge or incorporated into the sponge itself. The cleaning pad 714 may also be a single-use wipe or which may be used a number of times before being removed and discarded.
  • Turning now to FIG. 26A, therein is depicted a cleaning head 750 having a neck portion 702 and depending from the distal end therof, a bar portion 720 having downwardly depending therefrom a resilient flexible strip 722. The neck portion 702 includes a threaded recess 706 which includes mating threads which are adapted to receive corresonding threads present on body (not shown) used to form a combination cleaning device. A fluid conduit 708, depicted in dotted lines extends from the interior of the neck portion 702 where it extends into the interior of the bar portion 720 wherein it divides into a plurality of fluid conduits 708A, 708B and 708C each of which includes a corresponding outlet, 724A, 724B and 724C. The cleaning head 750 is particularly useful in cleaning glass or polished surfaces as a quantity of a chemical cleaning composition may be dispensed from the combination cleaning device, wherein said composition is distributed through the bar portion 720, whose resilient flexible strip 722 can be used to thereafter squeegee the treated glass or polished surfaces.
  • Turning now to FIG. 26B, therein is depicted a cleaning head 770 having a neck portion 702 and depending from the distal end therof, a bar portion 720 having both an outwardly depending resilient flexible strip 722, and a downwardly depending strip of an absorbent material, 726 which in preferred embodiments may be a sponge. While not shown in the figure, it is contemplated that an abrasive wipe or other flexible abrasive web may be associated with the absorbent material 726, such as the web disclosed in U.S. Pat. No. 6,120,506, the contents of which are herein incorporated by reference. The neck portion 702 includes a threaded recess 706 which includes mating threads which are adapted to receive corresonding threads present on body (not shown) used to form a combination cleaning device.
