The present invention relates generally to deodorisation and treatment of urine in urinals and, in particular, to a cartridge for such purpose.
BACKGROUNDBoth flushing urinals and waterless urinals are commonly known and used. Flushing urinals are considered costly due to water wastage and water treatment costs. Waterless urinals are increasingly popular due to decreased water consumption and wastage. Flushing urinals can be converted to waterless urinals, but at relatively high cost.
Waterless urinals generally utilize a one-way valve which opens in the presence of urine to allow the urine to flow to a sewage trap. The valve then closes to prevent urine odours developing in the bathroom area. However, urine odours still commonly permeate bathrooms where waterless urinals are used. Cartridges containing disinfectant and/or scent are commonly used to mask this odour, but rarely mask the odour completely. Such cartridges are normally placed in a urinal to lie above the urinal wastehole. Urinal wasteholes are not normally plugged in the manner of kitchen or bathroom sink plugholes.
Similar cartridges of disinfectant and/or scent are often used in flushing urinals for deodorising purposes. Urinal cartridges containing biological substances which break down odour-causing ammoniacal compounds in urine are also available. Such cartridges require water to flow over the biological substance in order for the biological substance to dissolve and treat urine. Cartridges of this type are normally placed in a urinal to lie above or over the wastehole of the urinal. Cartridges containing any of disinfectant, scent or biological substances require frequent replacement for a flushing urinal as excess flush water dissolves the disinfectant, scent or biological substance.
The plumbing systems of both flushing and waterless urinals clog over time due to a build-up of urea from the flow of urine and scale from the flow of water through the piping of the plumbing system. This can lead to costly repairs and maintenance.
A need therefore exists for cost-effective methods of deodorising and preventing clogging of plumbing systems for both flushing and waterless urinals. A further need exists for cost-effective conversion of flushing urinals to waterless urinals.

A plurality of ledges 214 protrude generally horizontally inwardly from the wall 210 as seen in
The ledges 214 are preferably distributed uniformly around the cylindrical wall 210 of the shell 200, as seen in
Returning to
A wall 307 is formed between the lip 304 and the base 302 and has a section 308 that extends generally vertically from the lip 304 to an inclined section 310 that joins the base 302 and which allows for the different diameters mentioned above. The inclined section 310 may allow the insert 300 to at least partially protrude into a urinal wastehole, as discussed later. In further implementations, as seen in
A plurality of generally L-shaped slots 312 are formed in the insert 300. The slots 312 extend from the section 308 and into a perimeter of the base 302, as seen in
The diameter of the lip 304 and the extent of the protrusions 306 are sized to permit limited engagement between the insert 300 and the shell 200, sufficient to hold the insert 300 loosely slidably adjustably within the shell 200. The insert 300 can be positioned by way of resilient flexibility of the plastics material from which the insert 300 is manufactured such that on insertion of the insert 300 into the shell 200, the protrusions 306 ride up and over the ledges 214. The height 305 of the insert 120 is preferably similar to, but slightly greater than, the height 220 of the wall 210 of the shell 200. The plurality of protrusions 306 provide for the resilient flexibility of the lip 304 due to the plastics material from which the insert 300 is manufactured. In other implementations, a single annular protrusion may be provided on the lip 304.
Insert 300 is normally supplied with deodorant block 110 placed inside the insert 300. In a preferred implementation, the deodorant block 110 is a bio-enzymatic substance which deodorises and biologically treats urine, and is soluble in the presence of urinal liquids including one or both of urine and water. The bio-enzymatic substance operates to reduce or eliminate urinal odours and decrease scale build-up in urinal plumbing by breaking down the composition of urea in urine.
As seen in
The insert 300 containing the deodorising block 110 can be positioned within the shell 200 of the assembly 100 by pushing the insert 300 into the shell 200 so that the protruding edges 306 of the insert 300 are pushed past the protruding ledges 214 of the cylindrical wall 210 of the shell 200.
The two-part structure of the assembly 100 provides for ease of assembly and dis-assembly, permitting ready placement of deodorising block 110, or the insert 300, or the shell 200, as may be required. Further, once fitted within the shell wall as seen in
Deodorising and treatment of urinal liquids will commonly be desired at the wastehole of a urinal.
In use the cartridge assembly 100b is positioned in the urinal 400b on the fixture 405b, such that the supports 204 of the shell 200b rest on or outside the annular ring 404b. In ideal placement, the base 302 of the insert 300b containing the deodorising block 110b sits on the ring 404b or substantially covers the wastehole fixture 405b. Urinal liquids such as water or urine can therefore flow under the edges 206 and 212 of the shell 200b and through the slots 312 of the insert 300b, dissolving the deodorising block 110b before flowing into the wastehole fixture 405b. If assembly 100b is moved during use to partially cover the ring 404b, a portion of the urinal liquids will likely still flow under the edges 206 and 212 of the shell 200b and through the slots 312 of the insert 300b, dissolving the deodorising block 110b.
Urinal wastehole fixtures will vary in size and shape according to different designs and manufacturers. A urinal 400c is seen in
If any of assemblies 100a, 100b and 100c were placed on an uneven surface or on a urinal with steep side walls, the slidable adjustable engagement of the shell with the corresponding insert would allow the base of the insert to lie close to or on a desired area of the urinal. However, such assemblies should be used in an area of a urinal through which liquids can flow freely—placement in a clogged urinal such that the insert of the assembly soaks in urinal liquids will cause rapid dissolution of the deodorising block 110.
In the preferred implementation, as the biological substance of the deodorising block 110 is soluble in both water and urine, the urinal cartridge deodoriser cartridge assembly 100 of the present disclosure can be used to convert a flushing urinal to a waterless urinal.
Urinal deodoriser cartridges may be provided in a variety of sizes, depths and widths and with a variety of aesthetic adornments or designs. Modifications and/or changes can be made thereto without departing from the scope and spirit of the invention, the embodiments being illustrative and not restrictive.
Some urinals may be operated such that a pool of water is provided in a basin of the urinal when the urinal is not in use. In such cases, the insert 300 may lie in the pool of water. The tablet 110 will thus be at least partially submerged in the pool at all times, and thus would typically dissolve rapidly. Owners or maintainers of a bathroom may also wish improve appearance of a urinal, whether waterless or flushing, by removing the urinal wastehole from sight. In such cases, an adapter device 600, as shown in
The adapter device 600 is preferably formed of a similar plastics material to the shell 200 or the insert 300.
As shown in
The second section 640 comprises a ring-shaped ledge 604 protruding substantially vertically outwardly from an outer edge of the surface 602, and connected to the surface 602 by a thin plastic join 606. The second section further comprises a substantially cylindrical side-wall 610 extending generally downwardly from a periphery of the ledge 604 to form a ring-like periphery 611 that operates as a base of the device 600 to rest upon a surface such as a surface of the urinal. A plurality of vertical struts 646 are formed on an inner surface of the wall 610.
As illustrated in
The core section further comprises an annular outer wall 614 extending downwardly from a periphery of the surface 602, almost parallel to the wall 612. The wall 614 has a peripheral edge in which preferably a plurality of notches 616 are formed, creating a castellated appearance. The wall 614 preferably has a height equal to or greater than the sidewall 307. Relatively, the wall 612 may be shorter than illustrated in comparison to the wall 614. Thus, if the section 620 retaining the assembly 100 were placed on a surface (such as a urinal surface), the insert 300 would not touch the surface.
As seen in
Referring back to
The side-wall 610 further comprises a frustoconical portion 605 connected to the ledge 604. The portion 605 is configured to bend inwardly by flexibility of the plastics material from which the device 600 is formed when pressure is applied thereto.
As shown in
The device 600 thus provides a number of means of adjusting the position of the base 302 of the insert 300 relative to the surface of the urinal and is thus suitable for use in a wide variety or urinals, and with various depth pools of urinal fluids. The device 600 is further easily adapted by a user for placement in urinals of various depths and widths.
If any of the frangible strips 642 are removed, the peripheral edge remaining rests on a surface of the urinal 700 and allow fluids to pass under the second section 640. The thin plastic join 606 provides means of adjusting the position of the insert 300 relative to the surface of the urinal. Thus, variations in depths of urinal pools and/or variations in size of urinal can be accounted for. The adapter also provides means of covering the urinal wastehole to improve appearance.
In some embodiments, dimensions of the device 600 may be altered according for appearance or purpose, or to fit alternate sizes of urinal deodoriser cartridges.
The device 600a has a slot 613a of radius shorter than that of the slot 613 of the device 600 as indicated in measurements 802 and 802a. In some embodiments, the edge 608 of the device 600 may be lengthened, such as the edge 608a of the embodiment 600a. The radius of the surface 602 may be correspondingly varied, such as the shorter radius of the surface 602a in the embodiment 600a. The embodiment 600a is shown after a user has applied pressure to depress the insert 602a within the device 600a. The surface 602a is further configured to slope downwardly as a user applies pressure to the insert 620a of the device 600a (similarly to
In some embodiments, the device 600 may be used for retaining an object other than the assembly 100.
In the context of this specification, the word “comprising” means “including principally but not necessarily solely” or “having” or “including”, and not “consisting only of”. Variations of the word “comprising”, such as “comprise” and “comprises” have correspondingly varied meanings.
