Abstract
Official abstract text for this publication.
An anti-splash device for urinals, including a porous member adapted to be detachably attached to an inner surface of a urinal is disclosed. The porous member holds a composition including an odour inhibiting and/or odour masking substance. A visual indication of the need of replacement is given by the composition when the odour inhibiting and/or odour masking substance is getting used-up.
First claim
Opening claim text (preview).
1 . An anti-splash device ( 1 ) for urinals, said anti-splash device comprising a porous member adapted to be detachably attached to an inner surface ( 3 ) of a urinal ( 2 ), wherein said porous member holds a composition comprising an odour inhibiting and/or odour masking substance, characterized in that said composition provides a visual indication of when said odour inhibiting and/or odour masking substance is getting used-up. 2 . The anti-splash device according to claim 1 , characterized in that said visual indication is provided by a change of colour of said composition. 3 . The anti-splash device according to claim 2 , characterized in that it is said odour inhibiting and/or odour masking substance per se that changes colour. 4 . The anti-splash device according to claim 2 , characterized in that said change of colour is provided by a colorant comprised in said composition. 5 . The anti-splash device as claimed in claim 3 or 4 , characterized in that said odour inhibiting and/or odour masking substance and/or colorant has an acidic pH and changes colour when its pH rises above a pre-determined threshold. 6 . The anti-splash device as claimed in claim 3 or 4 , characterized in that said odour inhibiting and/or odour masking substance and/or colorant has an alkaline pH and changes colour when its pH drops below a pre-determined threshold. 7 . The anti-splash device according to claim 1 , characterized in that said visual indication is provided by said composition comprising said odour inhibiting and/or odour masking substance being gradually decoloured or washed away by urine and/or water to expose an underlying surface of said porous member. 8 . The anti-splash device according to claim 7 , characterized in that said composition has a colour different from the colour of said porous member. 9 . The anti-splash device according to claim 8 , characterized in that it is said odour inhibiting and/or odour masking substance per se that has a colour different from the colour of said porous member. 10 . The anti-splash device according to claim 7 or 8 , characterized in that said composition comprises a colorant that is washed away by urine and/or water at the same rate as the odour inhibiting and/or odour masking substance. 11 . The anti-splash device according to any of the preceding claims, characterized in that said odour inhibiting and/or odour masking substance is chosen from the following group of substances: antimicrobial substances, odour adsorbent substances, scents, enzyme inhibiting substances, pH neutralizing substances, surfactants. 12 . The splash device as claimed in any of the preceding claims, characterized in that said porous member is chosen from the following group of structures: cellular structures, fibrous structures, nets. 13 . The anti-splash device as claimed in claim 12 , characterized in that said cellular structure is a honeycomb structure.
