Abstract: A dispensing screen for dispensing, by evaporation, volatile materials applied thereto, is provided. The screen comprises a sheet of material and diverting means formed in the plane of the sheet. The diverting means form a minimum path length along the length of the sheet between at least a portion of a first edge and an opposing second edge of the sheet, which minimum path length is longer than the distance between the first and second edges along the surface of the sheet. A dispensing apparatus is also provided, which in embodiments includes the dispensing screen of the invention, and in embodiments includes a sink for capturing un-evaporated volatile material.

Abstract: A dispenser for dispensing volatile material by evaporation comprises a reservoir for containing volatile material to be dispensed. The dispenser further comprises a dispensing screen for dispensing volatile material by evaporation, the dispensing screen comprising a sheet of material having continuous first and second edges and forming a continuous loop of material extending between the first and second edges. Communicating means can carry volatile material from the reservoir to an in use upper edge of the dispensing screen. The material of the dispensing means is acutely angled to an in use vertical axis of the dispenser.

Abstract: An emanator (24, 60) for a volatile material comprises an elongate element having a first plurality of fibres (12, 68) distributed along its length and extending therefrom or substantially perpendicular thereto. The emanator further comprises a fluid pathway for the conveyance of volatile material along the emanator. The pathway comprises one or more second fibres (14, 64) substantially extending in a direction along the length of the element.

Abstract: According to the invention, there is provided a valve, and also dispensing or dosing apparatus (1) incorporating such a valve, for dispensing a predetermined dose of a first liquid into a second liquid, the apparatus comprising a sealed reservoir (10) for holding the first liquid, a reservoir outlet tube (24) connected to the reservoir at its in use upper region (18) and in fluid communication therewith, first valve means (30) for selectively dispensing a dose of the first liquid from the reservoir into the second liquid, and a dosing tube (26) between the reservoir outlet tube and the valve means.

Abstract: A dispensing means (10) for delivering a dose of a first liquid into a second liquid is provided, the dispensing means comprising an enclosure (12) for the first liquid, and valve means (16), the dispensing means being operable such that raising a level (114) of a second liquid relative to the dispensing means so as to subject the dispensing means to hydrostatic pressure causes a dose of the first liquid to be displaced from the enclosure (12) to establish a column (118) of the first liquid that acts on the valve means, and subsequent lowering of the level (114) of the second liquid relative to the dispensing means so as to reduce the hydrostatic pressure acting on the valve means (16) causes the valve means to deliver the dose.

Abstract: A dispensing device for suspension from a rim of a lavatory bowl to dispense an additive into a flow of water when the lavatory is flushed, the device comprising a receptacle for the additive, dispensing means (36, 42, 60) operable when subjected to the flow of water to dispense a portion of the additive into the water, a guide member (20) slidable between an extended position and a retracted position and operable to direct the flow of water onto the dispensing means (36, 42, 60), and a hanger engageable with the rim of the bowl to suspend the device in the bowl, wherein the device further includes biasing means (58, 62) arranged to urge the guide member (20) into the extended position, such that when the dispensing device is suspended from the rim, the guide member (20) engages with a wall of the bowl.

Abstract: A closure (2) for a container (3), the closure (2) being engageable with a container (3) to close the container (3) and/or having a first part engageable with a second part to close a container (3), wherein the closure (2) has an orifice (11) and has a source of fragrance (8), and includes a chamber (9), or, when the first part is engaged with the second part, forms a chamber (9), the chamber (9) containing the source of the fragrance (8), the closure (2) being arranged such that, when used to close a container (3), the chamber (9) is separated from an internal space of the container (3) and vented to the surroundings of the container (3) by the orifice (11), and compression applied to the chamber (9) causes a puff of the fragrance to be emitted from the chamber (9) through the orifice (11) into the surroundings of the container (3).

Abstract: A dispensing means for delivering a dose of a first liquid into a second liquid is provided, the dispensing means comprising an enclosure (2, 3, 4) for accommodating the first liquid (12, 13), and dispersion means (15, 16), the dispersion means being adapted to receive a dose of the first liquid from the enclosure, and to deliver a dose of the first liquid into the second liquid when subjected to a flow of the second liquid. The dispersion means comprises a structure (15, 16) along which the first liquid is transportable and, in use, substantially all of the surface area of the dispersion means is exposed to the atmosphere. A surface of the dispersion means is curved such that the flow of the liquid when incident upon the surface is drawn over at least a portion of the surface.

Abstract: A liquid delivery device is particularly suited for dosing a toilet bowl with cleaning agents. Liquid from a reservoir flows through an inner sleeve of a connector into a cup until the liquid level reaches the mouth of the inner sleeve. Web is perforated so that the space in cup is open to atmosphere. Liquid is drawn from the cup by a capillary formed between the wall of cup and the connector and delivered to a porous pad. Flushwater runs over pad and supporting plate to disperse the liquid into a toilet bowl.

Abstract: A liquid delivery device is particularly suited for dosing a toilet bowl with a viscous cleaning agent. Liquid from a reservoir 10 flows through a neck 52 into a cup 18 until the liquid level reaches the mouth 54 of the neck 52. The space 14 in cup 18 is open to atmosphere. Liquid is drawn from the cup 18 by a capillary 66 formed between the wall of cup 18 and an insert 60 and delivered on to the surface 72 of a textile layer 6. Flush water runs over textile layer 6 to carry the liquid into a toilet bowl.
