Definitions

  • This invention relates to toilet brushes of the type used for cleaning toilet bowls, urinals, and other sanitary equipment e.g. sinks, bath tubs, shower and the like.
  • the invention is concerned with brush of the kind suited for dispensing a liquid.
  • toilet brushes of all types and for all purposes are collectively referred to as toilet brushes.
  • toilet brushes A wide variety of toilet brushes is known in the art for cleaning toilets, urinals, bath tubs, showers and other sanitary equipment, weather for domestic use or institutional (i.e. industrial or commercial cleaning personnel who are engaged in cleaning large numbers of toilets and urinals on an essentially constant or continuing basis throughout a workday.
  • US Patent Serial No. 6,966,720 discloses a toilet cleaning apparatus comprising a toilet brush head; a toilet brush handle separated from the brush head by a brush shaft; a portion of the brush handle being adapted to contain a cleaning fluid and being in fluid communication with the brush head by a conduit; the handle being adapted to be reciprocally displaced along the conduit between a first position remote from the brush head and a second position proximate to the brush head so urging cleaning fluid from the handle to the brush head; and, a non return valve within the conduit adapted to allow the flow of fluid from handle to brush but to prevent the flow of fluid from brush to handle.
  • W00165969A1 is concerned with a brush fitted with means for dispensing cleaning liquid that comprises a cleaning liquid reservoir and can be set to at least one non-dispensing mode and one dispensing mode. At least in the non-dispensing mode, the dispensing means can be locked up in such a way that for unlocking an unlocking operation is required in addition to the operation required for changing the setting. Since this combined operation is of a certain complexity it prevents a discharge of cleaning liquid when it is handled by unauthorized users, e.g. children, or an unintended change of the dispensing rate during its use in the dispensing mode.
  • US Patent Serial No. 5984555 discloses a dual toilet brush comprising an elongate handle.
  • a first brush head is connected to a first end of the elongate handle for cleaning an interior surface of a bowl of a toilet.
  • a second brush head is connected to and extends outwardly from the first end of the elongate handle above the first brush head, for cleaning an overhanging rim of the toilet.
  • EP1625820 discloses a toilet brush has a hollow handle containing a reservoir for disinfectant or cleaning fluid which can be dispensed through the bristles.
  • the handle has a socket at its base, in which a spiral spring is mounted. This fits over a rod attached to the brush head.
  • liquid dispensing mechanism is normally closed and is hermetically sealed such that liquid does not leak there from, but substantially only upon activation of the dispensing mechanism.
  • a toilet brush comprising a cleaning head fitted at a proximal end of an elongate handle, said handle comprising a liquid-tight reservoir fitted with a liquid dispensing port at said proximal end; said liquid dispensing port being normally sealed by a sealing plug; and a push-button at a distal end of the handle for manipulating the sealing plug to unseal the dispensing port only upon depressing of said push-button; and wherein manipulating the sealing plug is carried out by a manipulating rod extending thorough the handle and being axially displaceable there within.
  • the cleaning head comprises an array of bristle tufts extending from a central core formed with a liquid duct being in flow communication with the dispensing port of the handle; said cleaning head comprises one or more liquid dispensing apertures being in flow communication with the liquid duct.
  • the cleaning head is formed with sponge-like material or with rubber bristles, etc. Still, the cleaning head may be detachably attached to the proximal end of the handle.
  • Figures 1 and 2 illustrating a toilet brush in accordance with the present invention generally designated 10 and comprising a cleaning head 12 and an elongate handle 14.
  • the cleaning head 12 is either a sponge-like member or an array of bristle tufts extending from a central core member 18 formed with a liquid duct 22.
  • the central core 18 is fixedly mounted over a proximal end 26 of the elongate handle 14 e.g. by screw coupling, snap fitting, etc.
  • the elongate handle 14 is a hollow liquid-tight reservoir 28 fitted at its proximal end 26 with a liquid dispensing port 30 (seen in enlarged scale in Figs. 4 and 6) being in flow communication with the liquid duct 22 of the cleaning head 12 such that a liquid dispensed into the liquid duct 22 flows through one or more liquid-dispensing apertures 36 into the cleaning head 12.
  • a liquid dispensed into the liquid duct 22 flows through one or more liquid-dispensing apertures 36 into the cleaning head 12.
  • at least inner walls of the liquid reservoir are made of or coated with a material durable to corrosive agents.
  • the liquid dispensing port 30 is normally sealed by a sealing plug 38 typically made of resilient material e.g. silicon rubber fixedly extending at a proximal end of a manipulating rod 40.
  • the sealing plug 38 is normally biased into sealing engagement of the dispensing port 30 by means of a coiled compression spring 46 bearing at one end against the sealing plug 38 and at an opposite plug against a wall portion 48 of the central core 18, supported over a central stud 50.
  • a sealing cap 56 which in the present example is screw coupled to the distal end of the elongate handle 14 in the sealingly-tight manner.
  • the manipulating rod 40 spans substantially the entire length of the elongate handle 14, terminating at a push-button 58 formed in the sealing cap 56.
  • a push-button 58 formed in the sealing cap 56.
  • manipulating rod 40 is coaxially retained within the elongate rod by a rod retention member 60 supporting the rod 40 though not interfering with its axial displacement.
  • the push-button 58 is in the form of a resilient member sealingly attached to the filling cap 56.
  • the resilient push-button may be molded into the filling cap.
  • the liquid reservoir 28 may be easily replenished with a suitable liquid, e.g. a disinfectant liquid, a deodorizing liquid, a color agent, etc., through the opening at the distal end of the elongate handle 14 whereby the device may be re-used many times and further, wherein the active liquid agent may be refilled at user's choice.
  • a suitable liquid e.g. a disinfectant liquid, a deodorizing liquid, a color agent, etc.
  • the arrangement is such that liquid will discharge through the dispensing port 30 and out through the one or more liquid dispensing apertures 36 only upon manipulating of the manipulating rod 40, namely by depressing the push-button.
  • This arrangement offers a leak-tight solution and a substantially drip-free arrangement owing to the fact that the sealing plug 36 extends at the very end, namely the proximal end 26 of the reservoir integrated within the elongate handle 14.
  • the fluid flow path at the open position of the device is illustrated in Fig. 4 and is represented by arrows.
  • distal end 56 of the elongate handle 14, together with the filling cap 56 form an ergonomic grip portion suited for one-handed gripping thereof and easy manipulation of the push-button 58, using one finger.
  • the elongate handle 14 is formed with a translucent portion 66 (Fig. 1) marked with in representative of the liquid level within the reservoir 28. It is appreciated that the elongate handle 14 may be entirely transparent or translucent or may comprise transparent or translucent portions, as described.
  • the toilet brush as principally similar to that disclosed in connection with the previous embodiments, however, formed with a somewhat different manipulating arrangement wherein the manipulating push-button 70 projects from a side wall portion of the handle 14' with a filling cap 72 sealingly screw coupled at a distal end of the elongate handle 14'.
  • distal end of the manipulating rod 40' is formed with an inclined surface 74 bearing against a correspondingly inclined sliding surface 78 formed at a rear end of push-button 70.
  • Push-button 70 is spring biased by coiled spring 82 so as to project from the elongate handle 14' and the arrangement is such that depressing the push-button 70 against the biasing effect of spring 82 in direction of arrow 84 entails corresponding axial displacement of the manipulating rod 40' about an axis substantially perpendicular to axis of displacement of push-button 70, however coaxial with the longitudinal axis of the elongate handle 14'.
  • Fig. 6 differs from the previous embodiment in that the sealing plug 88 is integrally formed with a biasing portion 90 in the form of an integrated bellow-type spring portion bearing at its proximal end against a shoulder 92 of the central core 18, whereby the sealing plug 88 is normally biased into sealing engagement of the dispensing port 30.
  • a biasing portion 90 in the form of an integrated bellow-type spring portion bearing at its proximal end against a shoulder 92 of the central core 18, whereby the sealing plug 88 is normally biased into sealing engagement of the dispensing port 30.
