The improved urinal apparatus is configured for insertion in an outlet of a urinal. The urinal apparatus includes a hollow body defining an upper housing and a clamp ring/lower housing. The upper housing provides an open chamber configured to receive and retain a consumable detergent/malodour counteractant and the clamp ring/lower housing is configured to support and retain a resealing valve, which is operable to allow flow of fluid, such as urine, from above, but is operable to prevent backflow from below the resealing valve. The urinal apparatus also includes a consumable cap element, which includes an axial opening at least partway through, wherein the opening is configured to receive at least part of the upper housing. A body of the cap element comprises a plurality of radially extending fins. One of the upper housing or the consumable cap element comprise an upper member comprising an array of holes, which facilitate fluid flow and insertion and extraction of the urinal apparatus as a unit.

Disclosed is a packaged kit of a plurality of date-specific urinal screens for facilitating the regular hygienic maintenance of urinals. Each of the screens contains at least one integral tab or “printpad” displaying one of a category of sequential time periods. The time-displayed printpad serves primarily as a notification of the insertion time, duration, and/or disposal/removal date applicable to an individual urinal screen. A user, subsequent to disposing of an expired urinal screen, will then insert the urinal screen displaying the next succeeding time period. A cavity which accommodates an enzyme block is located internally to each urinal screen, and serves to releases biodegradable surfactants. Each screen further comprises a plurality of ridges, spokes, crests, channels, various openings, and other physical features for the purpose of minimizing splashing and facilitating the flow of urine or flush water through the urinal.

A urinal screen device includes a body portion having one or more fold lines to allow the urinal screen, or a base portion of the urinal screen that sits in the urinal basin, to bend so as allow maximal coverage of the basin without compromising functionality. The fold lines are created by regions that lack the protrusions formed on body of the urinal screen to break up fluid streams and prevent back splash. The regions lacking protrusion allow the body to bend easier because there are no protrusions being forced against each other along the fold line.

A thermochromic device includes a base including a surface and an image provided on the surface of the base. A layer of thermochromic material covers at least a portion of the image provided on the surface of the base. When a temperature of the layer of thermochromic material changes across a predetermined magnitude, a visual characteristic of the layer of thermochromic material changes from a first condition, such as being opaque, to a second condition, such as being transparent or translucent.

A urinal and pipe cleaning composition and automated dispensing system and method. The composition preferably comprises urea hydrochloride, a thickener, optionally one or more surfactants, and optionally fragrance. Preferably, the surfactants comprise cocamidopropyl betaine and one or more ethoxylated alcohols. The composition preferably has a viscosity allowing it to be dispensed from an automated dispenser and to coat the surfaces to be cleaned to allow sufficient contact time to dissolve accumulated salts and remove stains. A predetermined dose of the composition is dispensed at predetermined time intervals. Different dose amounts and time intervals may be used depending on the level of usage of the urinal, the amount of salt scale, and level of staining.

The present invention discloses an electronic flush valve system for tankless water fixtures, comprising a valve housing and a replaceable flush valve module removably secured within the valve housing. The flush valve module is comprised of an independent, self-contained flush valve configured as a replaceable flush valve cartridge.

An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a carrier material that is somehow 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 through the emanator from a bulk supply; gas-pump drive of volatile fluid to the emanator at controlled pressure or volume; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof.

A coated smooth surface of a substrate repels liquids and viscoelastic materials and can have anti-staining and anti-biofouling properties. The smooth surface can be coated by applying a chemical layer on the surface and a lubricant. Such coated surfaces are useful for use in toilets, urinals, or other devices for the processing of liquids and viscoelastic materials such as solid or semi-solid metabolic waste of human digestive system. Such coated surfaces can also be applied to windows for buildings or vehicles such as automobiles or camera lenses to repel liquids (e.g., rain), ice, frost, insect residues, and birds' feces.

A urinal screen includes a main body portion, an first front portion, and a second front portion, which each include a plurality of protrusions configured to break up a stream of fluid incident on the urinal screen and prevent splash. The first front portion is separated from the main body portion by a first fold line, and the second front portion is separated from the main body portion by a second fold line. The fold lines lack protrusions, and meet at the front of the urinal screen. The main body portion and first and second body portions form a circular configuration when unfolded to fit circular urinal basins. The first and second front body portions can be folded upwards to produce a pointed configuration so that the urinal screen can then fit in urinals having a pointed basin.

The present invention discloses an electronic flush valve system for tankless water fixtures, comprising a valve housing and a replaceable flush valve module removably secured within the valve housing. The flush valve module is comprised of an independent, self-contained flush valve configured as a replaceable flush valve cartridge.
