Definitions

  • the present invention refers to an anti-splash device for urinals, said anti-splash device comprising a porous member adapted to be detachabiy attached to an inner surface of a urinary bowl and is intended to reduce splashing of urine.
  • the porous member holds a composition comprising an odour inhibiting and/or odour masking substance to freshen and sanitize the urinary bowl.
  • the odour of urine varies depending on concentration and variety of chemicals excreted by kidneys, which in turn depends on food intake and possible diseases.
  • the odour is also influenced by microbial and enzymatic activities.
  • the bad smell may for instance be generated by bacterial activity breaking down urea to ammonia.
  • the bad smell is caused by splashing of urine, occurring when a stream of urine hits the inner surface of the urinal. Due to the impact force, urine is dispersed into fine drops that travel a relatively long distance from the urinal, landing on the walls and the floor of the bathroom, as well as on the individual urinating. These drops are thus not removed upon flushing, but remain on the surfaces in proximity of the urinal, generating bad smell.
  • US 5,165, 1 19 discloses an anti-splash guard made of a decomposable plastic material containing an additive decomposing by microorganisms and sunlight characteristic. After the receptacle is used, the additive is naturally decomposed in a short time by activity of microorganisms and irradiation of sunlight, the plastic material collapses into a granular resin, and the receptacle loses its original form, thus indicating the need for replacement.
  • US 2007/0186337 discloses a non-splash urinal strainer with a perforated base pad and a deodorant canister fixed to the base pad. Deodorant material is contained within a space provided between the continuous outside wall and the funnel shaped conduit.
  • US 6,920,648 discloses a disposable, deodorant and splash proof urine dispersing device made of scented plastic material.
  • GB 2472377 discloses a liquid dispersion apparatus comprising a mat that has a surface arranged to carry information such as printed advertisements or health information, which may fade over time after repeated contact with urine to reveal another layer carrying different information.
  • the mat may carry an odour inhibiting and/or odour masking compound, a fragrance or a detergent and it has a surface pattern arranged to disperse the urine as it hits the surface of the mat.
  • an anti-splash device comprising an odour inhibiting and/or odour masking compound to maintain its deodorizing and freshening function
  • the anti-splash device needs to be replaced on a regular basis, since the odour inhibiting and/or odour masking compound is deactivated with time or is washed away upon repeated contact with urine. It may be difficult to know when replacement is needed just by trying to perceive the scent of the bathroom air, which may result in the replacement carried out too early or too late,
  • an anti-splash device for urinals comprises a porous member adapted to be detachably attached to an inner surface of a urinal.
  • the anti-splash device is preferably positioned at a location where a stream of urine is likely to hit the inner surface of the urinal, such as at the lower portion of the inner side wall being furthest away from the user, or at the outlet.
  • the porous member is arranged to hold a composition comprising an odour inhibiting and/or odour masking substance.
  • odour inhibiting is meant a substance that removes the cause of the odour and/or the odour.
  • odour masking is meant a substance having a strong scent that prevails over the odour.
  • the composition provides a visual indication of when the odour inhibiting and/or odour masking substance is getting used-up. This effect may be achieved either by providing a composition capable of changing its colour when the odour inhibiting and/or odour masking substance is getting used-up. or by providing a
  • composition that is gradually washed away by urine and/or water to expose an underlying surface of the porous member, which may have a contrasting colour to the colour of said composition in order to provide the desired visual indication.
  • any component of the composition may have the ability to change its colour.
  • the composition may comprise the odour inhibiting and/or odour masking substance that per se changes colour, it is also possible that the composition comprises a colorant able to change colour. It is sufficient that one of the components of the composition may change its colour, but it is also conceivable that several of the components of the composition have the ability to change its colour.
  • At least one of the components of the composition of the present invention may have an acidic pH ( ⁇ 7) when the anti-splash device is new.
  • the composition of the present invention may be adapted to change its colour when the pH rises above a pre-determined threshold.
  • the colour change is distinct from one colour to its complementary counterpart, for instance from purple to green, from orange to blue, or from yellow to violet.
  • the user or the maintenance service replaces the anti-splash device.
  • the acidic composition inhibits growth of bacteria, and thus reduces odours generated due to bacterial activity, in particular the release of ammonia from the breakdown of urea. Further, by the action of the acidic composition, the ammonia is conveniently neutralized by formation of an odourless ammonium salt.
  • Any component of the composition may also have an alkaline pH (>7). Upon repeated contact with urine and/or flushing water, and particularly with acidic odorous substances contained in the urine, the pH will decrease.
  • the composition of the present invention may be adapted to change its colour when the pH drops below a pre-determined threshold. Preferably, the colour change is distinct from one colour to its complementary counterpart, for instance from green to purple, from blue to orange, or from violet to yellow.
  • An alkaline composition can neutralize acidic odorous substances in urine, such as isovaleric acid and acetic acid. Also, the alkaline composition prevents growth of microorganisms, thus eliminating odours originating from microbial activity,
  • the visual indication may be achieved by the composition comprising the odour inhibiting and/or odour masking substance being gradually decoloured or washed away by urine and/or flushing water to expose an underlying surface of the porous member.
  • the colour of the composition is different from the colour of the porous member such that the user or the maintenance service easily notices the difference when the composition is getting used-up.
  • the colour of the composition and the colour of the porous member may be complementary to each other, such as purple/green, orange/blue, yellow/violet.
  • the odour inhibiting and/or odour masking substance per se may have a colour different from the colour of said porous member.
  • the composition may comprise a colorant that is washed away by urine and/or water at the same rate as the odour inhibiting and/or odour masking substance.
  • the dissipation rate for the odour inhibiting and/or odour masking substance and the colorant may be controlled by a binder.
  • the odour inhibiting and/or odour masking substance may be chosen from the following group of substances: antimicrobial substances (e.g. chlorhexidine, quaternary ammonium compounds, chelating agents, parabens, chitosan, hydrogen peroxide, botanical additives, acids, such as adipic acid, ascorbic acid, benzoic acid, boric acid, citric acid or lactic acid; metal salts), odour adsorbent substances (e.g.

  • composition according to the present invention may be a system comprising a coloured surfactant which is gradually decoloured or washed away by urine and/or water.
  • the surfactant helps to prevent splashing by reducing the surface tension of drops.
  • the odour inhibiting function of the surfactant is achieved by a cleaning action, and also, in cases when a cationic or an anionic surfactant is used, antibacterial action. Even in this case, the deodorizing and freshening function of the anti-splash device may be improved by addition of an odour-masking substance mentioned above.
  • the composition may comprise a surfactant and a colorant, wherein both the surfactant and the colorant are washed away at the same rate.
  • the composition according to the present invention may comprise a salt which is gradually dissolved and washed away by urine and/or water.
