Definitions

  • the present invention relates to a new and useful cleaning device particularly adapted for cleaning a toilet bowl and rim and for removing human waste there from.
  • the cleaning device of the present invention generally consists of a cleaning head (1) and a handle (4) characterized in that the cleaning head (1) is adaptable to the surface to be cleaned, and consists of a compressible inner core (2) and surrounds a flexible tip (5) of said handle (4), and wherein said inner core (2) is surrounded by a non-porous outer membrane (3), which is free of bristles.
  • Conventional toilet brushes comprise a handle with an arrangement of bristles at one end and are made using a variety of moulding, assembly and manufacturing processes. These bristles can be scraped across the surface of the toilet bowl and under the rim of the toilet bowl to clean this surface and to remove human waste there from.
  • the inner rigid core in the cleaning device of PCT publication WO2004/060106 limits the adjustability of the cleaning surface to the contours of the surface to be cleaned.
  • a further disadvantage of said cleaning device are the gaps and edges present within the cleaning head or at the attachment perimeter of the cleaning head to the handle, allowing the accumulation of dirt and a favorable environment for growth of bacteria.
  • the cleaning head has an inverted trapezoidal shape on which elastic projections are fixed. Due to this fixed shape of the cleaning head (i.e. inverted trapezium), again the adjustability of the cleaning surface to the contours of the surface to be cleaned, is limited. Furthermore, at the attachment perimeter of the cleaning head to the handle, dirt could accumulate, providing a favorable environment for the growth of bacteria.
  • the shape and deformability of the cleaning head will limit the conformability of the cleaning surface to the contours of the surface to be cleaned, and the flexible neck attachment of the cleaning head to the handle typically creates a collar allowing the accumulation of dirt and a favorable environment for growth of bacteria, and limits the handiness and force transfer, when applying the device for example to clean the overhanging upper edge or rim of water closet bowls.
  • FIG. 1 Shows a prior art cleaning device (A) and an embodiment of a cleaning device of the present invention (B) .
  • the cleaning device of the present invention has a handle (4) with a flexible tip (5) that extends into the lower half of the handle.
  • Figure 2 Shows the side view of an embodiment of a cleaning device of the present invention.
  • Figure 3 Shows a top view and frontal cross-section of the cleaning head of a cleaning device of the present invention.
  • the flexible extension is spoon shaped with a large opening for the adhesion of the compressible inner core.
  • Figure 4 Shows a further embodiment of a cleaning device of the present invention, wherein the flexible tip of the handle consists of three flexible extensions.
  • Figure 5 Shows a further embodiment of a cleaning device of the present invention, wherein the flexible tip of the handle consists of two flexible extensions.
  • Figure 5B shows a cross-section of the cleaning head comprising edges (9) to fit the flexible extensions of the tip of the handle.
  • the cleaning device of the present invention generally consists of a cleaning head (1) and a handle (4) characterized in that the cleaning head (1) consists of a compressible inner core (2) and surrounds a flexible tip (5) of said handle, and wherein said inner core has a non-porous outer membrane (3) .
  • the cleaning head (1) consists of a compressible inner core (2) and surrounds a flexible tip (5) of said handle, and wherein said inner core has a non-porous outer membrane (3) .
  • the deformable cleaning head may be any shape, including circular, oval or square.
  • the cleaning head is ovoid or drop-shaped. The latter not only plows better through the water surface and prevents gushes, but also contributes to the water- repellency of the cleaning device of the present invention.
  • a further element contributing to water- and dirt-repellency of the cleaning device is the non-porous outer membrane (3) which, particularly consists of a water-repellent material; in particular of rubber or a rubber-like material such as silicon- and polyurethane-based polymers, e.g. silicone rubbers, or a similar material.
  • the outer membrane typically has a smooth surface, but as will be apparent to the skilled person, textured and even slightly abrasive surfaces are within the admit of the present invention.
  • the cleaning head does not retain water and dries quickly after use.
  • the instant dryness of the device after use significantly contributes to the hygiene of the cleaning device. Since debris automatically resides in the water bowl, and doesn't stick to the cleaning head, excess flushing to clean the latter is no longer required.
  • This dirt repellent feature together with the instant dryness reduces the spread of water, human waste and potentially harmful bacteria outside the toilet bowl and therefore, the likelihood of a pool of water, which can provide a breeding ground for potentially harmful bacteria, accumulating in the base of a holder used to store the toilet-cleaning device.
  • the water repellent properties of the cleaning head means that it may not be essential to store the device in a holder. For example, as it does not retain water after use, it can be stored on a hook.
  • the outer membrane (3) of the cleaning device of the present invention preferably comprises a plurality of integrally formed resilient deformable protrusions (6).
  • the pluralities of integrally formed resilient deformable protrusions (6) are each and independently selected from cones; cylinders; or from dots having a convex top surface. Said protrusions are spaced from one another, i.e. not close to one another, but sufficiently spaced to prevent the accumulation of dirt between the protrusions.
  • the protrusions are present on the outer membrane (3) with a density of from about 0,5-3 units/cm 2 , in particular about 1,5 units/cm 2 .
  • the cleaning head is drop-shaped.
  • the upper hemisphere of said drop shaped cleaning head has at most five integrally formed resilient deformable protrusions; and is in particular free of integrally formed resilient deformable protrusions.
  • the protrusions at the upper hemisphere of the drop-shaped cleaning head are positioned distal from the handle.
  • the flexible tip in the cleaning device of the present invention typically consists of one or more, i.e. 2, 3, 4 or 5, flexible extensions (7) at one end of the handle.
  • the plurality of flexible extensions increase the conformability of the pressure level to the contours of the surface being cleaned and accordingly contributes to the effectiveness and ease in handling of the device of the present invention.
  • a plurality of flexible extensions (7) mimics the anatomy of fingers on a hand, allowing an optimal, clearly defined, but subtle deformation of the cleaning head vis-a-vis the contours of the surface to be cleaned.
  • the one or more flexible extension is spoon shaped, optionally comprising one or more apertures. The latter allow and improve the adhesion of the compressible inner core around the flexible tip.
  • the one or more flexible extensions (7) are typically an integral part of the handle (4), and the flexible tip (5) may extend into the lower half of the handle.
  • the handle is typically formed from a first rigid thermosetting plastic backbone, which extends into a thinner and accordingly flexible tip (5) .
  • the flexible tip additionally being formed at least partially from a resilient elastomer.
  • the upper part of the handle can be made of any rigid material, such as for example wood; a rigid thermosetting plastic; or metal, such as for example inox.
  • Any resilient elastomer can be used, such as for example a polyolefin selected from the group consisting of styrene- butadiene-styrene, styrene-isoprenestyrene, styrene- ethylene/butylene-styrene, polypropylene and related copolymers .
  • the compressible inner core (2) can be formed of any known resilient or semi-resilient porous, non-porous or partially porous materials and/or combinations thereof, such as for example silicon- and polyurethane-based polymers, e.g. silicone rubbers.
  • the compressible inner core may consist of an open structure with a plurality of ribs (8) and edges (9) from a resilient or semi-resilient material. In the latter embodiment some of said edges or ribs may interact with the flexible extensions of the tip of the handle, in order to position the head (1) relative to the handle (4) .
  • the compressible inner core of the cleaning device is further characterized in that it consists of an open structure, such as for example an air filled cavity, optionally with a plurality, i.e. 2, 3, 4, 5, 6, 7 or more of ribs (8) and edges (9) from a resilient or semi-resilient material; in particular the compressible inner core of the cleaning device is further characterized in that it consists of an open structure with a plurality, i.e. 2, 3, 4, 5, 6, 7 or more of ribs (8) and edges (9) from a resilient or semi- resilient material.
  • the compressible inner core of the cleaning device is further characterized in that it consists of an open structure with a plurality, i.e. 2, 3, 4, 5, 6, 7 or more of ribs (8) and edges (9) from a resilient or semi- resilient material.
  • 2, 3, 4, 5, or more of said edges or ribs engage with the flexible extensions
  • the inner core (2) is composed of resilient foam material, such as polyurethane (PU) open cell, PU closed cell, or a similar material.
  • PU polyurethane
  • the non-porous outer membrane (3) and the compressible inner core (2) are made of the same material, which, particularly consists of a water-repellent material; in particular of rubber or a rubber-like material such as silicon- and polyurethane-based polymers, e.g. silicone rubbers, or a similar material.
