Abstract
Description
- The present invention relates to sealed odor traps for waterless urinals, and it is more particularly directed to Improvements in the internal structure of oil-sealed odor traps for prolonging sealant retention and for protection against high pressure water flushing.
- With increasing emphasis on water conservation, there is renewed interest in toilets and urinals designed to minimize the amount of water consumed in flushing to mitigate excessive demands on water supplies as well as on wastewater disposal systems, both of which have tended to become overloaded with increasing populations.
- Sanitation codes require urinals to provide an odor seal to contain gasses and odors which develop in the drain system: this function is conventional performed by the well known P-trap or S-trap in which the seal is formed by a residual portion of the flushing water. This seal effectively locks in sewer odors from the drain-pipe beyond the trap, however the upward-facing liquid surface communicates freely with the user environment, so that the crap must be kept free of residual urine by copious flushing to prevent unacceptable odor levels from the liquid in the crap; therefore a large amount of water is consumed in flushing these conventional urinals. Especially in the U.S. over many years when water was cheap and plentiful, conventional flushing type urinals and wafer-wasteful toilets held an unchallenged monopoly. However more recently, threatened and real water shortages have aroused new environmental concerns and heightened conservation awareness as evidenced by the introduction of low flush toilets.
- As the cost of water increases and budgets tighten, the prospect of a viable water less urinal system becomes extremely attractive to a wide range of public agencies, cities, states, penal institutions, defence establishments, recreational and parks departments and the like. Waterless urinals utilizing oil-sealed odor traps are becoming viable. However, the present inventor has discovered that a key factor in their potential is the attainment of low maintenance, and that this is largely dependent on the longevity of the liquid sealant, which in turn is related to the internal structure of the odor trap.
- The use of an oil as a recirculated flushing medium in a toilet system was disclosed in
U.S. Patent No. 3,829,909 (Rod, et al. ). - The use of oil in toilets to form an odor trap has been disclosed in German Patent No,
121356 (Beck, et al. ) and inU.S. Patent Nos, 1,050,290 (Posson ) and4,028,747 (Newton ). - Other examples of oil-sealed traps are found in German Patent No.
2816597.1 , and Swiss Patent No.803,846 (Ernst - German Patent No.
2816597.1 discloses an oil-sealed trap located in the sewer drain of a urinal system that is capable of holding an oil sealant. The shows a large vertical baffle separating the trap into entry and discharge sections and inlet openings in the entry section adjacent the large vertical baffle. In addition, an overflow standpipe extends down below the floor portion of the trap. This reference is taken in forming the preamble ofclaims 1 and 2. - A key parameter of oil-sealed odor traps for waterless urinals is the amount of sealant depletion that takes place under normal service conditions over periods of time and frequency of usage. Related to this is the possible partial or complete loss of sealant due to the abnormal condition of unnecessary but unavoidable high pressure flushing with water. While some modem oil-sealed odor traps are considerably improved over early versions, there remains an unfulfilled need for further improvements in the above-described aspects of sealant preservation.
- It is an object of the present invention to provide an improved odor trap for a flushless urinal in which the escape and therefore the depletion of the liquid sealant is effectively prevented, by causing stray droplets of sealant drifting buoyantly in the flow path to return to the main sealant body.
- It is a further object to provide an improved odor trap by which loss of sealant is effectively prevented in the event of high pressure flushing with water, which though not required, can occur inadvertently. The odor trap should be adapted to be easily Installed and removed from a permanent drain terminal plumbing fixture.
- It is a further object of the present invention to provide an improved odor trap which eliminates the need for a P-trap in the drain line, is economical and easy to manufacture and install and performs reliably and efficiently with low maintenance requirements.
- According to the present invention, a drain odortrap is provided as defined in
claim 1 and as defined in claim 2. Embodiments of the odor trap are defined in the claims 3 to 19. Further, according to the present invention, a system for draining wastewater is provided as defined inclaim 20. - The present odor trap departs from the conventional practice of a predominantly vertical flow of wastewater through the trap. Instead, the trap is structured in a manner such that a substantial portion of the total flow path is made to be generally horizontal and to be located in a region where stray droplets of sealant, due to buoyancy, will migrate upwardly back to the main sealant body, either directly or as guided by a sloping baffle configuration. Thus, escaping of sealant down the drain is largely prevented.
- The odor trap is preferably configured such that it can be economically made from two molded plastic parts, i.e., a main compartment part and a cap/baffle part, that can be molded from plastic and joined by thermal bonding into a unit configured as a replaceable cylindrical cartridge that can be charged with sealant and sealed with a sticker for shipment so that upon Installation it is necessary only to install the cartridge and remove the sticker.
- In service, required maintenance, i.e. sealant checking and replenishment, if and when needed, can. be easily performed with the unit in place.
- The cartridge is preferably shaped to be easily pushed into place by hand and held frictionally in a mating recess provided by a casing that can be installed as part of the host piumbing in a urinal. For drain cleaning or replacement purposes, the odor trap can be removed with a special simple hand tool.
- The shape of the entry compartment preferably provides a sheltered region to which sealant tends to be temporarily displaced in the event of high pressure water flushing, thus avoiding catastrophic sealant loss.

FIG. 1 is a mid cross-sectional view of an odor trap 10A of the edge-entry trap configuration of known type for example as disclosed inDE 2 816 597 , configured as a cylindrical cartridge. - Odor trap 10A has a main
liquid container 14 extending from an outer wall to an inner wall that forms adrain stand pipe 14A defining at its upper edge the overflow level of liquid in thecontainer 14. Anoverhead cap portion 16 is formed to provide avertical baffle 16A extending down intocontainer 14 dividing it into an inner discharge compartment and a surrounding entry compartment. A body ofresidual urine 18 extends up to the overflow level at the top ofstand pipe 14A, and in conjunction with the overhead plenum region formed by thecap portion 16, the residual body ofurine 18 serves to trap sewer gasses from the external drain line in accordance with plumbing codes. - A body of oily
liquid sealant 20, lighter than water or urine, floating in the entry compartment on top of the trapped body ofurine 18, serves to trap odors from theurine 18 from escaping from trap 10A. - In operation of the urinal, urine from above, near the outer edge separates into droplets that permeate through the layer of
sealant 20 and then join the main body ofurine 18. As additional urine enters the body ofurine 18, it overflows thestand pipe 14A and the over-flow portion gravitates down the drain. - Know oil-sealed odor traps are configured as in
FIG. 1 with avertical baffle 16A. From actual experience, traces of sealant can escape during usage. Such depletion occurs as follows: in a form of turbulence or emulsification during each usage event, despite the inherent buoyancy of thesealant 20 due to its low density and the non-affinity to water/urine, some droplets of sealant can separate from the main body and get swept downward along with the main flow of urine in the outer chamber. These stray droplets will tend to decelerate due their inherent buoyancy and, depending on downward urine flow velocity and travel depth, some of them may come to rest and then reverse and rise against the flow to return to the main sealant body above, and are thus recovered, However, any droplets that get dragged by the urine flow past the bottom of thebaffle 16A, will then accelerate upwardly in theinner compartment 18 due to their buoyancy and will then escape down the drain conduit instand tube 14A. - The present invention can be implemented with the same general cylindrical exterior shape as that of the odor trap shown in
FIG. 1 , and can be made to fit into a cavity receptacle that is part of a urinal system having anentry bowl portion 12A above, leading to tapered upper edges of the outer wall of the main liquid container of odor trap 10A and extending downward around the trap 10A to a reduction portion 12B which connects by regular plumbing attachments to the external drain system. -
FIG. 1A is a simplified schematic representation of the left hand half of the asymmetrical configuration ofFIG. 1 which is coaxial about a central axis C-C', showing again the relation ofsealant 20,urine 18 and asealant flow path 22 in the urine in the entry compartment. It is evident that in this configuration due to the vertical orientation ofbaffle 16A, theflow path 22 is pre-dominantly vertical: downward in the outer compartment as shown and upward in the inner chamber, with only relatively small horizontal components around the bottom ofbaffle 16A and around the top ofstand tube 14A. Flowpath 22, havingsealant 20 overhead, is the only portion of the total flow path where sealant recovery can occur, thus a corresponding parameter can be estimated as indicated by dimension X, representing the effective sealant-recovery horizontal flow path length. In a typical odor trap of the category ofFIGS. 1 and 1A , with the mainliquid container 14 having an inside radius R as indicated = 5.4 cm and thebaffle 16A having an outside radius of 4 cm, the horizontal recovery dimension X is about 0.8 cm, from which we can express the unit-less ratio X/R = 14.8% characterizing this particular internal structure. - The component X labelled in the FIGS. Is an approximate average of the horizontal vector components X of the wastewater flow, extending from the middle of the entry opening (e.g. the point of average entry of the wastewater into the sealant) to a furthest point along the flow path (e.g, around the baffle) in which sealant recovery can occur. Although the invention contemplates a value X based on the approximate average, generally all of the wastewater will follow a flow path having a component X, e.g. any wastewater not following such a flow path would be insubstantial enough to effect the proper functioning of the invention -- such as if extraneous openings were provided allowing a minimal volume flow rate therethrough.
- A vertical vector component Y of the flow path can be approximately defined as the vertical distance from the top of
stand pipe 14A to the bottom ofbaffle 16A. Accordingly, an alternative feature can be based on a ratio X/Y, which can be used to estimate an effective slope of the flow path - for example, X/Y < 1 indicating a predominantly vertical flow path and X/Y > 1 indicating a predominantly horizontal flow path. - This category of odor trap is vulnerable to total loss of sealant if subjected to water-flushing at high pressure, due to the relatively narrow width of the outer compartment and absence of any sizeable shelter compartment around the entry region to which sealant can be displaced temporarily by the flushing water instead of being forced down the drain.
-
FIGS. 2-8 are simplified cross-sectional functional diagrams representing various odor trap configurations illustrating embodiments of the present invention, which is directed to preservation of sealant. For simplicity, as inFIG. 1A , only half of asymmetrical cross-sections are shown, along with a central axis. The shapes shown generally apply to structure that is coaxial about the axis shown, but the invention could be practiced by applying such cross-sections to other, non-co-axial and/or non-symmetrical configurations such as rectangular containers or cylindrical containers with non-coaxial internal structure. -
FIG. 2 is a conceptual diagram illustrating an embodiment of the present invention wherein an odor trap 10B is structured in a novel manner. Rather than making the baffle vertical as inFIGS. 1 and 1A , at least a portion of the baffle is shaped in a non-vertical manner to cause the liquid flow path to be predominantly horizontal, as a major departure from entirely vertical baffle and consequent predominantly vertical liquid flow that has been universal in known art as described above. - The baffle in
FIG. 2 has avertical portion 16A, facing the vertical wall ofdrain riser 14A, and aninclined portion 16B sloping up to thecover 16C which has anentry opening 16D at the left. The contour of the bottom portion 14B of the mainliquid containers 14 is shown for simplicity as forming a flow path of substantially constant depth, however in practice there can be a much greater variation in depth along the flow path. - From the
entry opening 16D at the left, the flow is to the right. The liquid flow path has tworecovery portions portion 22A, starting at the entry Inlet, the flow is horizontal, passing under the main body ofsealant 20. Then inportion 22B the flow path slopes downward but remains predominantly horizontal as directed by thesloping baffle portion 16B. The flow path turns abruptly upward at the plane ofvertical baffle portion 16A, to overflowriser 14A and then exits down the drain in the same manner as inFIGS. 1 and 1A . - it is evident that in both flow
path portions FIGS. 1 and 1A . - In
FIG. 2 within the path length X indicated, practically all stray sealant droplets migrating upwardly to the top side of the flow path will be recovered and returned to the main body ofsealant 20. Inflow path portion 22A the body ofsealant 20 is directly overhead, and alongportion 22B the slope ofbaffle 16B redirects upwardly-migrating stray sealant back to the main body ofsealant 20, as indicated by the curved arrows. Since sealant recovery occurs along both of these portions, the recovery dimension X as shown is the sum of the horizontal components of the two portions. - The cross-section of
FIG. 2 can be applied to a coaxial cylindrical structure having a central axis about the line C-C' and the outer wall of cylindrical container being at D-D', such as thewall 14 as shown. Alternatively, the cross-section ofFIG. 2 can be applied in reverse manner to provide a coaxial cylindrical odor trap structure of the central-entry type with a central axis at D-D' and the outer wall of the cylindrical container at C-C', - As a further alternative, the cross-section of
FIG. 2 can represent that of an enclosure that is other than cylindrical, e.g. rectangular. In addition, the container can alternatively be made with side walls at both D-D' and C-C' such that a non-symmetrical, non-axial, device is formed. - A coaxial structure based directly on
FIG. 2 would tend to be shallower and larger in diameter than cartridge shaped as shown inFIG. 1 . As a practical limitation, a minimum liquid depth is required in the trap to meet regulations regarding containment of sewer gas pressure in the drain system: e.g., 2 Inches in the United States and 50 mm in Europe. Due to existing urinal space limitations, cylindrical traps are typically limited to a maximum diameter of about 150 mm (5.9") and a maximum height of about 90 mm (3.54"). To function properly in such a compact size, the conceptual example shown inFIG. 2 is preferably reconfigured in shape with the wasted space between thebaffle portions cover 16C more preferably being utilized. - The principles and advantages in sealant retention Illustrated in
FIG. 2 can be realized in various odor trap configurations constructed and arranged to meet particular practical requirements, such as shown in the following examples. -
FIG. 3 depicts the structure of an edge-entry odor trap 10C having the baffle configured with a verticalupper portion 16A and asloped portion 16B as shown, providing aflow path 22 corresponding to horizontal recovery dimension X as shown, extending from an averaged entry point to the extremity of slopedbaffle portion 16B. - In
FIGS. 2 and3 , as viable baffle shape variations, thevertical portion 16A could be located anywhere along the slopedportion 16B between the extremes shown in these two FIGS., while keeping the slopedportion 16B as shown: basic functioning and dimension X would be virtually unaffected. -
FIG. 4 depicts an odor trap 10D as a variation ofFIG. 3 havingbaffle 16B sloped in its entirety. Theflow path 22 and the dimension X are approximately the same as inFIG. 3 . -
FIG. 5 depicts a center-antry odor trap 10E wherein the baffle is configured with a verticalupper portion 16A and a horizontallower portion 16B flanged outwardly as shown. This creates a folded liquid path havingupper portion 22A above andlower portion 22B as shown. Only theupper portion 22A will be effective in returning stray sealant because thebaffle 16B is not sloped. Thus, stray sealant in theportion 22B will tend to get swept along to the right and escape to the drain along with the effluent. The horizontal recovery dimension X will be as indicated, derived from the upperflow path portion 22A. -
FIG. 6 depicts an odor trap 10F as a variation ofFIG. 5 wherein thelower baffle portion 16B is sloped as shown so as to recapture stray sealant from the lowerhorizontal flow path 22B, thus adding to theupper path 22A to yield the much greater horizontal recovery dimension X indicated. -
FIG. 7 depicts an odor trap 10G as a variation ofFIG. 6 wherein the sloppedflange portion 16B is made to have an oppositely-slope upper surface which serves to prevent accumulation of debris on the flange's upper surface which could otherwise occur in this region in the structure ofFIG. 6 . Dimension X is virtually the same as inFIG. 6 . -
FIG. 8 depicts an odor trap 10H as a reversed version of the foregoing center entry coaxial configurations which achieves a form of predominantly horizontal flow path with a simplevertical baffle 16A surrounded by adrain stand wall 14A' which sets the overflow level.Wall 14A', surrounded by an outer wall extending down from the circumference of thecover 16C, is attached to the circumference of the floor 14B so as to form a simple cylindricalmain container pan 14 which can be supported by the surroundingsaver 16C or drain housing 12B by radial vanes (not shown). The center entry causes the liquid to spread out radially in a sloped but substantiallyhorizontal flow path 22 leading to the bottom edge of thebaffle 16A as shown, corresponding to recovery dimension X as indicated. - In
FIGS. 5-8 , a triangular-shaped empty region can be seen in cross-section above the sealant, as formed by the slope of the cover. This triangular region serves an important function as a sealant shelter region into which the sealant tends to be displaced in the event of high-pressure water flushing, instead of being forced down the drain ahead of the flushing water, as could occur with trap structure of known art, such as inFIGS. 1 and 1A , having the conventionalvertical baffle 16A and the conventional predominantly vertical flow paths. -
FIG. 9 is a three-dimensional view of a cylindrical odor trap cartridge 10I withcenter entry 16D in accordance with a preferred embodiment of the present invention. The upper surface slopes downward in a shallow inverted cone toward the center where theentry opening 16D is fitted with a filter screen or a fine perforation pattern formed in the cover material. - The enclosure can be, for example, dimensioned about 11.4 cm (4 1/2") in diameter and 7.0 cm (2 3/4") in height. As noted, due to existing industry limitations, the size of the trap is to be limited. For example, the diameter of the trap is preferably between 5.0 to 6.4 cm (2 to 2 ½ inches). It is preferably molded from polyethylene, or from another suitable plastic material such as polypropylene, ABS or polystyrene, to provide a smooth stain-resistant surface. The material can also include a fiberglass reinforced polyester. Other suitable materials can also be utilized. Typically, the
main container 14 and cap/partition part 16 are molded as separate parts and then bonded together to form an integral enclosure, sines access to the interior is not normally required. The entry configuration of trap 10I makes it feasible to seal theentry opening 16D (with the bottom exit opening, not visible inFIG. 9 , sealed in a similar or other manner) for shipment as a cartridge already charged with sealant, ready for deployment. For example, to seal theopening 16D, a sticker can be attached thereto, such sticker can further include labelling, etc., such as installation instructions and product labelling. -
FIG. 10 is a three-dimensional cutaway view of a center-entry cylindrical odor trap 10J having a non-coaxial interior configuration, shown without liquid for clarity. The baffle has two fiat portions:vertical portion 16A extending downward from the upper surface offset to the right ofentry opening 16D. At the bottom ofvertical baffle portion 16A, ahorizontal portion 16B extends fully to the left hand wall of odor trap 10J, Around opening 16E, about the same size asopening 16D, is configured in ahorizontal baffle portion 16B at the edge furthest fromvertical baffle portion 16A. Opening 16E leads into a lower compartment which is configured with a fiat floor 14B of which a portion is extended upwardly at the right hand side to form tubular drain stand 14C whose top edge defines the overflow level of the container as in the FIGS. described above. The twoliquid flow paths path 22A. -
FIG. 11 depicts an odor trap 10K which is a variation having a baffle configured as inFIG. 10 but wherein thedrain riser 14D is here configured as a flatvertical riser wall 14D attached integral to floor 14B and to the inferior wall of themain enclosure 14 of odor trap 10I., preferably molded together in one piece. -
FIG. 12 is a central cross-section depicting an odor trap that represents an important variation applicable to bothFIG. 10 and FIG. 11 . Thehorizontal baffle portion 16B is sloped in a manner to recover stray sealant and return it to the main body of sealant 10. The resultant horizontal recovery dimension X is much longer than inFIGS. 10 and 11 due to the additional recovery provided by the sippedbaffle portion 16B. - It is seen that the cross-sections of
FIGS. 10 and 11 generally resemble that ofFig. 5 , and the cross-section ofFIG. 12 generally resembles that ofFIG. 6 . However, preferred constructions according toFIGS. 5 and 6 as shown imply fully coaxial internal and external configuration centered on axis C-C' whereas the internal structure inFIGS. 10-12 is clearly non-coaxial with the outlet offset rather than centered and the baffles flat rather than cylindrical. - The relative sealant recovery effectiveness of the above configurations as approximated by the recovery-effective length of the horizontal flow paths X relative to container radius R can be compared in the following estimated table. The following Table 1 lists examples of estimated values which can be achieved for X/R in the illustrated embodiments, the illustrated embodiments not being limited thereto:
TABLE 1 FIG. X/ R 1, 1A 15% 2 76% 3, 4, 5 50% 6, 7 105% 8 56% 10, 11 71% 12 165% - Alternatively, the relative sealant recovery effectiveness of the above configurations, as a few exampies, can be expressed as a function of the flow path slope X/Y. The following Table 2 lists estimated examples of values which can be achieved for X/Y in the illustrated embodiments, the illustrated embodiments not being limited thereto.
TABLE 2 FIG. X/ Y 1, 1A 0.12 2 4.64 3, 4 3.50 5 5.50 6 5.75 7 8.60 8 3.67 10, 11 3.08 12 5.82 - According to the preferred embodiments of the present invention, the inlet and outlet locations and the baffle configuration, etc., result in a predominantly horizontal flow, For example, the preferred embodiments of the present invention yield values of X/R > 30%, as distinguished, for example, from predominantly vertical flow of known art in the above table. As seen in Table 1, the present invention can even yield values greater than 50%, allowing for a wide margin above the 15% estimated for the noted prior art. The present invention provides values of X/Y of greater than 1.0, while the above-noted estimate of the noted prior art achieves a value substanlially less than 1.0.
- It is recognized that as a one-dimensional parameter such as X/R is merely a first approximation of effectiveness: a more refined two-dimensional parameter could take into account the effective horizontal recovery area located above the flow path. An even more refined three-dimensional parameter could take into account fluid viscosities, width, depth and length and resulting flow velocities at various incremental points in the flow paths.
- The relative effectiveness indicated by the above tables apply to normal operation and does not necessarily include the additional improvement in protection against catastrophic loss of sealant under the condition of high pressure water flushing as described above. In this regard, according to another embodiment of the invention, a shelter region is provided for the sealant. Such a shelter region can be provided in any of the embodiments of the invention. The configurations of the embodiments of, for example,
FIGS. 10-12 include entry compartments with shelter regions (e.g., T shown inFIG. 12 ) wherein high-pressure flushing water tends to take a direct path from entry opening 16D to baffleopening 16E while parting much of the sealant and temporarily pushing it into the shelter regions at both sides. Among other things, the angled top wall and the wide entry compartment helps provide such shelter regions. The shelter region is preferably formed by an airspace above the normal sealant level, such as shown within T inFIG. 12 . In order to allow the sealant to quickly enter the shelter region, the device can include one or more air vents to allow air within the shelter region to vent outside thereof. For example, the embodiment shown inFIG. 12 includes at least oneair vent 16F at an upper end or the trap. Theair vent 16F is preferably sized to allow air to pass therethrough while substantially preventing fluid flow therethrough, and preferably has a diameter of about 1-2mm, As shown, the air vent is preferably in the top wall of the device. In this manner, in the event the any sealant is forced through the air vent, the sealant can be redirected along the upper surface and Into theupper opening 16D so as to return to the body of sealant. -
FIG. 13 shows another preferred embodiment of the invention. The device shown inFIG. 13 employs a number of features which are similar to certain features shown inFIGS. 10-12 ,FIG. 13 is a three-dimensional cutaway view of an odor trap 10M having a non-coaxial interior configuration. The baffle has a generallyvertical portion 16A extending downward from the upper surface, offset to the right ofentry opening 16D, and ahorizontal portion 16B extending fully to the left hand wall of odor trap 16M at the bottom ofvertical baffle portion 16A. The horizontal baffle extends only partially across the trap so as to leave anopening 16E at the edge furthest fromvertical baffle portion 16A. Theopening 16E leads into a lower compartment which is configured with a floor 14B. A tubular drain stand 14C is provided which extends upward at the right hand side of the floor 14B. The top edge of the drain stand 14C defines the overflow level of the container. The twoliquid flow paths FIG. 12 -- e.g., the sum X1 + X2 from thepaths FIG. 13 , a body ofwastewater 18 has asealant layer 18 buoyantly floating thereon. Thewastewater 18 follows the flow path a) 22I into theentry opening 16D, b) 22A above the baffle, c) 22B below thebaffle 16B, d) 22C up and over the top edge of thedrainstand 14C, and e) 22D down the drain stand 14C. -
FIGS. 15-18 show one preferred construction of the embodiment shown inFIG. 13 . This preferred construction includes a top member 150 (FIG. 15 ), a middle member 160 (FIG. 16 ), a bottom member 170 (FIG. 17 ), and a plug member 180 (FIG. 18 ). Thetop member 150 includes a generallycylindrical perimeter wall 151, a downwardly inclinedtop wall 152, and anentry opening 153 at the center of the top wall. Thetop wall 152 Is inclined In a manner like that InFIG. 13 . As shown, the entry opening preferably includes threeholes 154 in the center area of the top wall. The top wall also preferably includes two sealingridges 155 for receiving and sealing the baffle 165 (discussed below). - The
middle member 160 includes aperimeter wall 161 and a baffle having a generallyvertical portion 165 and an upwardlyinclined portion 166. Theportion 166 has a generally straightupper edge 167 providing afluid passage 168 around the baffle. - The
bottom member 170 includes aperimeter wall 171, abottom wall 172, and a upwardly extendingdrain stand 173. The drain stand preferably is a cylindrical tube extending above thewall 171 with an upper opening 175 and alower opening 176. The lower edge of the bottom member can, for example, as shown include atapered wall 174. - The device is assembled with the middle member fitted such that the
perimeter wall 161 snugly fits within theperimeter wall 151 and thebaffle portion 165 snugly fits between theridges 155. Thewall 151 only extends down over part of the height of thewall 161. Thelower member 170 fits with thedrain stand 173 within the area to the right of thebaffle portion 165 and the lower portion of thecylindrical wall 161 snugly fitted within thecylindrical wall 171. As a result, a sealed container can be constructed having separately isolated entry and discharge compartments. -
FIG. 18 shows a plug-handle member 180 which can be included in this latter embodiment. The plug-handle member 180 preferably includes atubular member 181, handleprojections 182, and L-shapedprojections 183 at theupper wall 184. The plug is preferably shaped and sized so as to snugly fit within thedrain stand 173. With this construction, the odor trap can be transported with a body of sealant within the assembled structure, if aplug 180 is inserted in theopening 176 and a seal (such as an adhesive backed label) is placed over theopening 153. As shown, the L-shaped projections are sized and shaped to fit within theholes 154 so that the assembled device can be carried by simply inserting the projections into theholes 154 and rotating theplug 180 in the direction L,FIG. 18 , so that the L-shaped projections engage under thetop wall 152. Thus, themember 180 provide a tool that can be used to seal a new, unused, unit and to remove a dirty, waste-water filied, unit. Although the plug and handle functions are preferably combined into thesingle tool 180, it is contemplated that separate devices embodying these features can be included and/or either the plug or handle can be eliminated depending on the desired handling. - The
sealant 20 is preferably a biodegradable oily liquid. A preferred composition ofliquid 20 comprises an aliphatic alcohol containing 9-11 carbons in the chemical chain, wherein the specific gravity is 0.84 at 68 degrees Fahrenheit. Since the operation of the urinal is based on the differential between the specific gravity of the olly liquid and that of urine, typically near 1,0, the specific gravity of the oily liquid should be made as low as possible, preferably not exceeding 0.9 and, more preferably, well under 0.9. The sealant preferably 20 is chosen to have a very low affinity to water such that sealant and the urine strongly repel each other physically so that there Is no chemical or other interaction apart from a purely physical separation which allows urine/water from above to divide finely and permeate downwardly through the sealant layer. Thesealant 20 is preferably colored, e.g. blue, for maintenance and identification purposes. -
FIG. 14 shows one example of type of urinal into which the various odor traps, shown generally as 10, can be located. The illustratedurinal 140 being a wall mounted unit attached above a floor surface (not shown). The urinal shown Is for illustrative purposes only; a trap of the present invention can be used in any type of urinal.
