A method for dispensing an active volatile in the environment surrounding a surface, which comprises applying to the surface a self-adhering, water-resistant gel composition of at least one active volatile ingredient, silica, and a water-soluble cationic polysaccharide, and diffusing or releasing the volatile ingredient(s) from the gel in an amount sufficient to purify or sanitize the surrounding air, both in a dry condition or in the presence of humidity or water. The gel composition remains adhered to the surface and actively releases the volatile ingredient(s) even after being exposed to repeated water flows over the composition.

An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. Preferred devices dispense a first agent for air freshening, and may optionally dispense a second agent, such as a drain cleaner. A workable drain cleaner is structured to permit a slow release of drain cleaning agent. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a polymer or rubber-like carrier material that is infused with the volatile fluid; gravity-induced drip from a bulk supply of volatile fluid through a small orifice onto an emanator; osmotic transfer of volatile fluid from a bulk supply; gas-pump drive of volatile fluid at controlled pressure; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof.

Lavatory treatment devices comprise a lavatory treatment composition which includes: up to 50% wt. of an adhesion promoter constituent based on a fatty alcohol polyglycol ether as may be represented by the following structural formula (I):
ROCH.sub.2CH.sub.2O.sub.nH(I)
within which, R is an C.sub.12-C.sub.24 aliphatic mono- or poly-alkene moiety, and n has a value of from 1 to 50; 0.01-25% wt. of an organic solvent constituent, which is liquid at room temperature (20 C.); 0.1-25% wt. of a detersive surfactant constituent; optionally a co-adhesion promoter constituent, preferably based on one or more oxyalkylenated compounds; further optionally one or more further optional constituents which may impart a further aesthetic or technical benefit to the said lavatory treatment compositions; and, to 100% wt. of water. Preferably the lavatory treatment compositions of the lavatory treatment devices are ringing gels.

Embodiments of the present invention provide urinal screens for reduced splashing. The urinal screen includes an outer ring and a web portion. The web portion includes a plurality of web strings disposed in a mesh pattern such that a plurality of open areas are defined between the web strings. Portions of the web strings forming a first face of the web portion configured to receive urine in use are substantially rounded in profile.

A system for the metered dispensing of a fragrance in a toilet, in particular in a lavatory of a vehicle, comprises a fragrance container having a fragrance stored in a receptacle, and a port carrying the fragrance and joined with the receptacle for guiding the fragrance out of the receptacle. The port is connectable with a flushing pipe for the toilet.
