Description

[0001] APPARATUS FOR AUTOMATED MECHANICAL DISPENSING OF FRAGRANCE INTO TOILET BOWL

[0002] RELATED APPLICATIONS

[0003] This Application claims the benefit of priority of U.S. Provisional Patent Application No. 63 / 764,757, filed February 28, 2025, entitled “Fragrance Dispenser,” the contents of which are hereby incorporated by reference as if fully set forth herein.

[0004] TECHNOLOGICAL FIELD

[0005] The present disclosure relates to the field of dispensers, and more specifically, but not exclusively, to an apparatus that is configured to dispense a fragrance into a toilet bowl in a mechanical fashion, both automatically when a user sits on a toilet seat and in response to user activation.

[0006] BACKGROUND OF THE INVENTION

[0007] Various techniques have been developed for dispelling the odors that pervade in a bathroom following defecation. These include: spraying a fragrance within the bathroom; absorbing the odor with baking soda or charcoal, or operating a fan. These techniques share a general strategy in that they address the odors only after they have emanated into the bathroom, and thus cannot prevent the unpleasant smell.

[0008] SUMMARY OF THE INVENTION

[0009] The present disclosure introduces an apparatus for dispensing fragrances into a toilet that operates based on mechanical actuation. In a typical embodiment, the dispensing mechanism is based on air displacement. The reservoir containing the oil is connected, via a fluid line, to a nozzle that dispenses the oil into the toilet bowl. Application of pressure at two or more separate and independent locations causes dispensing of oil out of the fluid channel and into the toilet.

[0010] In particularly advantageous embodiments, the apparatus enables dispensing of odor-blocking oils into the toilet using two independent mechanisms: an automatic mechanism which is triggered by sitting of the user on the toilet seat, and a voluntary mechanism which is triggered by depression of a soft button that is adjacent to the toilet bowl. The fluid line passes from the reservoir, which is outside the toilet bowl, across the rim of the toilet bowl, to a nozzle that is within the toilet bowl. When the fluid line isfull, application of air pressure toward the fluid line (e.g., by sitting on a toilet seat which is positioned over an actuator for the automatic mechanism) causes expulsion of the oil through the nozzle. The expelled fluid is replaced with ambient air. Subsequent depression of the actuator causes additional fluid to enter the fluid line from the reservoir and to be thus in position to be dispensed into the toilet bowl.

[0011] According to a first aspect, an apparatus for automated release of fragrance into a toilet bowl is disclosed. The apparatus includes: a reservoir for storing therein the fragrance, a nozzle configured for delivery of the fragrance into the toilet bowl, and a fluid conduit for delivery of the fragrance from the reservoir to the nozzle; a first mechanical actuator for manual discharge of fragrance from the nozzle upon manual actuation by a user by actuation from the side; and a second mechanical actuator for automated discharge of fragrance from the nozzle upon application of pressure from above. Depression of either of the first and second actuators causes displacement of air from the fluid conduit, thereby causing spraying of the fragrance into the toilet bowl. Advantageously, the dual actuation mechanism enables automatic actuation when the user sits as well as manual actuation by the user’s hand when he or she is already sitting.

[0012] The first mechanical actuator may be configured on an outer face of the reservoir and may include a depressible button. The first mechanical actuator may include a piston. Depression of the button or piston may cause compression of the reservoir, thereby causing displacement of fluid from the reservoir into the fluid conduit. Any other mechanical mechanism may also be used for delivering the fluid from the reservoir to the fluid conduit.

[0013] An air conduit may connect the second mechanical actuator to an inlet of the fluid conduit, such that depression of the second mechanical actuator causes displacement of fluid through the fluid conduit.

[0014] The apparatus may include a mount for mounting the reservoir, actuator, and nozzle onto the toilet bowl. The mount may include: a horizontal arm extending approximately at a right angle from the reservoir; and a vertical arm extending approximately at a right angle from the horizontal arm and parallel to the reservoir, such that, when mounted on the toilet bowl, the reservoir is configured outside the toilet bowl, the horizontal arm is configured over an edge of the toilet bowl, and the vertical arm is at least partially configured within the toilet bowl. Other mounting configurations, such as those utilizing snap-fit, springs, or elastics, are also possible.The nozzle may be configured at an end of the horizontal arm; or along or below the vertical arm.

[0015] The vertical arm may be adjustable relative to the horizontal arm to match a width of a rim of the toilet bowl. For example, the vertical arm may comprise a movable latch configured to secure the vertical arm to a rim of the toilet bowl. Optionally, the horizontal arm and vertical arm are formed integral with each other and together form part of a U-shaped element that is configured to fit securely over a rim of the toilet bowl.

[0016] The second mechanical actuator may be configured on the horizontal arm. The second mechanical actuator may be arranged between a toilet bowl rim and a toilet seat, such that, when a user sits on the toilet seat, the second mechanical actuator is automatically depressed.

[0017] According to a second aspect, an apparatus for automated release of fragrance into a toilet bowl is disclosed. The apparatus includes a reservoir for storing therein the fragrance, a nozzle configured for delivery of the fragrance into the toilet bowl, a fluid conduit for delivery of the fragrance from the reservoir to the nozzle; at least one mechanical actuator for discharge of fragrance from the nozzle, and an adjustable mounting mechanism configured to fit a wide range of ceramic toilets using an adjustable latch-lock mechanism for the purpose of securing the reservoir to the toilet.

[0018] Optionally, the adjustable mounting mechanism includes both vertical and horizontal adjustment capabilities to ensure the container hangs in a firm, stable position even when pressure is applied to the at least one mechanical actuator.

[0019] The adjustable mounting mechanism may include a horizontal arm including ridges, a vertical arm including ridges, a latch on the vertical arm that is configured to be fixed at each of the ridges of the horizontal arm, and a vertical location lock configured to be fixed at each of the ridges of the vertical arm. Other mounting configurations, such as those utilizing snap-fit, springs, or elastics, are also possible.

[0020] In some embodiments, the at least one mechanical actuator comprises a side-mounted button on the container body. This actuator may be voluntarily dispensed by a user sitting on the toilet seat. The apparatus may further comprise a second mechanical actuator consisting of a soft upper button configured to be positioned between a toilet bowl rim and a toilet seat. This actuator may be depressed whenever the user sits on the toilet seat.Some embodiments include a dual-activation mechanism allowing for both direct activation via a side button and indirect activation via an upper button connected to the fluid conduit through an air pass channel.

[0021] The nozzle may be configured to prevent backflow or clogging through the use of one-way valves, self-cleaning mechanisms, or anti-clog geometries. The nozzle may comprise an adjustable dispensing angle mechanism allowing users to direct the spray or dispensing pattern to target specific areas within the toilet bowl.

[0022] The mounting mechanism may include shock-absorbing or vibration-dampening elements to maintain stability during toilet usage. The mounting mechanism may utilize non-permanent, non-damaging attachment methods such as tension grips, silicone pads, or adjustable clamps that do not require drilling or permanent modifications to the toilet.

[0023] The dispensing mechanism may utilize mechanical pressure amplification to require minimal user force for activation, making it accessible for users with limited hand strength or mobility.

[0024] The apparatus may include a visual indicator showing reservoir level, dispensing status, or activation confirmation.

[0025] The soft upper button may be designed with a low profile to prevent interference with the toilet seat and to maintain comfort for the user.

[0026] According to a third aspect, an apparatus for delivering fluid to a water surface in a plumbing fixture is disclosed. The apparatus includes: an actuator; a support; and a nozzle; wherein the support is configured to retain the actuator in a first position that is outside the fixture and the discharge outlet in a second position that is inside the fixture; and the actuator is configured to propel fluid out of the nozzle.

[0027] The apparatus may further include a first vessel containing a reservoir located outside the plumbing fixture; wherein the actuator is configured to propel fluid from the vessel to the nozzle. In some such embodiments, a second vessel is arranged within the plumbing device, wherein the discharge outlet is fixed to the second vessel.

[0028] The support may include a hollow channel that is configured to provide fluid communication between the first vessel and the second vessel. Optionally, in the hollow channel, a tube may be present that is configured to receive the fluid from the first vessel. The support may be sufficiently flexible such that, when installed on the fixture, the second vessel is biased toward the first vessel so that the first and second vessels maintain contact with a wall of the fixture.The first vessel may include a pump that is configured to be actuated by the actuator. The actuator may include a piston that extends outside the first vessel.

[0029] The support may be configured to traverse a rim of the fixture. The support may be further configured to be disposed between the rim and a seat of the fixture. In embodiments when the fixture includes a spacer that retains the seat at a height above the rim, the support may have a thickness that is no greater than the height.

[0030] The support may be configured to maintain the discharge outlet at a position that is above a resting water level of the fixture.

[0031] The apparatus may further include a second vessel, and a ballast that is disposed in the second vessel. The ballast may be configured to hold substance that operationally acts as a counterweight to the first vessel.

[0032] The discharge outlet may include a first channel that, in a downstream direction, feeds into multiple second channels. The discharge outlet may also define a dispensing orifice and the second channels feed into the dispensing orifice.

[0033] The actuator may be configured to actuate a piston pump, or may be part of a piston pump.

[0034] The actuator may be configured to be manually activated.

[0035] When the fixture includes a seat, the actuator may be configured to be activated by deformation of the seat, or by mechanical loading of the seat.

[0036] The discharge outlet may be configured to discharge essential oil, and / or a mixture of essential oil, alcohol and emulsifier.

[0037] In another implementation, an odor-neutralizing system for a toilet includes a fluid dispersion mechanism configured to spray, dispense, or otherwise deliver active substances; a reservoir containing an active substance; and a mounting means configured to attach the system to, within, or adjacent to a toilet; wherein the system is operable to disperse, spray, or dispense the substance into the toilet bowl water, below the water surface, above the water surface, or into the surrounding air, to prevent or reduce unpleasant odors. The active substance may include a natural essential oil selected from the group consisting of eucalyptus, peppermint, lavender, lemon, or any combination thereof. The active substance may comprise a gel, foam, dissolvable powder, or synthetic deodorizing compound. The active substance may be configured to modify the appearance, texture, or chemical properties of the toilet water surface.The fluid dispersion mechanism may be selected from the group consisting of: spray nozzle, dispenser, drip emitter, vaporizer, foam generator, dissolvable capsule dispenser, metered dose dispenser, controlled release mechanism, atomizer, nebulizer, electrospray device, or ultrasonic dispersion unit. The mounting means may position the system at a location selected from the group consisting of: toilet lid, toilet bowl rim, inside the ceramic body, inside the flush tank, wall adjacent to the toilet, or ceiling above the toilet.

[0038] A manual actuator may be selected from the group consisting of: push button, foot pedal, or mechanical lever.

[0039] A visual indicator may indicate operational status or fluid level.

[0040] The reservoir may be replaceable via a removable cartridge, magnetic latch, or quick-lock mechanism. The reservoir may comprise two or more reservoirs for dispensing multiple substances. The dispersion quantity may be adjustable by a user.

[0057] DETAILED DESCRIPTION OF EMBODIMENTS

[0058] The present disclosure relates to the field of dispensers, and more specifically, but not exclusively, to an apparatus that is configured to dispense a fragrance into a toilet bowl in a purely mechanical fashion, both automatically when a user sits on a toilet seat and in response to a user activation.

[0059] FIG. 1 is a schematic diagram illustrating components of a system 1000 for spraying a fragrant oil into a toilet bowl. The system 1000 consists of an apparatus 1010 which is configured to spray the fragrant oil into a toilet bowl 1020. The internal components of the apparatus 1010 include a reservoir 1013 for storing the fragrant oil, a fluid conduit for delivery of the oil from the reservoir, and a nozzle 1015 for spraying the fragrant oil out of the apparatus. The nozzle 1015 is arranged so as to spray the oil into the water 1022 which is within the toilet bowl. The apparatus 1010 may have two or more mechanical actuators. There may be a manual actuator 1011 which is triggered by a voluntary action of the user. This actuator 1011 may be, for example, a piston or a depressible button. In addition, there may be an automatic mechanical actuator 1012. The automatic manual actuator 1012 may be situated beneath the toilet seat, such that, when a user sits on the toilet seat, the actuator is depressed. The apparatus 1010 further includes a mounting mechanism 1016, for mounting the apparatus 1010 onto the rim 1024 of the toilet bowl.For purpose of completeness, prior to analyzing specific physical embodiments of the system 1000, this disclosure will describe certain generic aspects of the fragrance and the toilet bowl into which the fragrance is sprayed.

[0060] Ingredients of the Fragrance. The fragrance may be contained in a substance including one or more of the following components: fluid, solid, powder, aerosol, gas, colloid, water, alcohol, emulsifier, antimicrobial agent, microbiocidal agent.

[0061] In preferred embodiments, the fragrance includes essential oils. Essential oil spray is a natural and effective method for neutralizing unpleasant odors. The essential oils may provide both a refreshing fragrance and antibacterial properties. The fluid may include natural essential oil. Natural essential oils may include volatile compounds. The compounds may be extracted from plants, some of which may be known for their distinctive fragrances and antibacterial properties. The fluid may include a carrier. The carrier may include water. The carrier may include an alcohol base. The carrier may facilitate spraying. The carrier may facilitate dispersion in the air. The carrier may facilitate dispersion on the water. The fluid may include an emulsifier. The emulsifier may promote dispersion in the air. The emulsifier may promote dispersion on the water. The emulsifier may promote mixing of the oil with water in the fluid. The emulsifier may promote mixing of the oil with water in the plumbing fixture.

[0062] Essential oils may provide odor control, cleaning and disinfection of disinfection, for example, of surfaces. Essential oils may provide fragrances to wardrobes and storage spaces. Essential oils may provide air purification in enclosed spaces. Essential oils may provide stress relief and relaxation through aromatherapy. Essential oils may create a fresh and pleasant atmosphere after toilet use. Essential oils may prevent or reduce mold and humidity buildup in damp areas. Essential oils may be non-toxic and ecofriendly. Essential oils may be free or near free of harmful synthetic chemicals. Essential oils may be safe for use around children and pets, unlike synthetic air fresheners which may contain toxic compounds. Biodegradable essential oils may break down naturally without polluting air or water. Essential oil scents may influence mood and well-being. Examples include lavender, which promotes relaxation and reduces stress, eucalyptus, which may help with respiratory issues and may clear airways. Lemon may enhance alertness and concentration. Patchouli may induce a sense of calm and emotional stability.

[0063] A user may blend multiple essential oils to create unique, personalized scents. Examples include green relaxing lavender plus vanilla plus chamomile, refreshing lemonplus orange plus peppermint, disinfecting tea tree plus eucalyptus, eucalyptus plus Rosemary.

[0064] Masking agents are essential oils that have a strong fragrance to cover unpleasant odors. Unlike regular shampoo or synthetic air fresheners, essential oils may do more than merely mask odors. Essential oils may interact with odor-causing molecules and may reduce the intensity of their odors.

[0065] Some essential oils, such as peppermint and clove, create a freshening effect that replaces a bad smell with a pleasant one. Tea tree oil and lavender, for example, contain antibacterial properties that may eliminate or reduce bacteria causing the odor. This leads to actual odor reduction rather than just temporary masking.

[0066] Odor neutralization occurs when essential oils break down and bond with the odor molecules. Essential oils with natural antibacterial compounds such as lemon and tea tree oil may attack bacteria and fungi responsible for producing unpleasant smells, thus reducing the formation of bad odors.

[0067] When the fluid is released into the air, essential oil particles may disperse and bind to odor molecules, helping to neutralize them. Certain essential oils, such as lemon and eucalyptus, may contain antimicrobial or microbicidal agents that may eliminate bacteria that produces unpleasant odors. Due to the volatile nature of essential oils, their scent continues to diffuse in the air for a period before they fully evaporate.

[0068] The duration of effectiveness of the fluid applied by the apparatus and methods may depend on the type of essential oil used. Volatile oils like lemon and lavender dissipate relatively quickly, (about 30 minutes to an hour). Oils like Patchouli and sandalwood may last longer (two hours or more).

[0069] The fluid may also include an anti-microbial or microbiocidal agent. The antimicrobial or microbiocidal agent may include any suitable metal, metalloid, transition metal ion or any other suitable element or ion. The metal ion may include Ag+, Cu+2, or Zn+2. The anti-microbial agent may have one or more of virus-inhibiting, virussuppressing, viricidal, bacteria-inhibiting, bacteria-suppressing, bactericidal, anti-biofilm, fungi-inhibiting, fungi-suppressing, fungicidal, protozoa-inhibiting, protozoa-suppressing properties, protozoicidal properties or any other suitable properties.

[0070] The layer or film formed by the fluid on the water may act as a natural barrier that coats feces prior to entering the water and that prevents odors from escaping into the air. The oil may start managing the odor prior to entrance of feces into the water, when theodor is released from feces in the toilet. The layer may trap odor molecules before the odor molecules can disperse into the air. The oil may evaporate from minutes to hours after application, depending on the composition of the oil and the fluid. When the oil evaporates, the oil may release a refreshing fragrance. The fluid or its components may help disinfect and reduce bacteria. This may help maintain hygiene in the toilet environment.

[0071] The different components may be mixed together prior to loading within the apparatus. In addition or in the alternative, the components may be stored in separate chambers and mixed prior to dispensing. The mixing may be based on a desired fragrance blend or odor management strength.

[0072] In some embodiments, the apparatus may further include air purification mechanisms that are not liquid-based, such as activated carbon filters, UV units, or ion field generators.

[0073] Toilet Bowl. In a typical embodiment, the fragrance is sprayed directly into the water of the toilet bowl into which a user will subsequently defecate. In such embodiments, the sprayed oil droplets rest on the surface of the water, forming a thin film on the water, thereby masking odors that may emanate from the toilet bowl. The toilet bowl may have any suitable shape (e.g., elliptical or circular) and may be made of any suitable material (e.g., porcelain). Alternatively, instead of mounting the apparatus on the toilet bowl, it is possible to mount the apparatus on a water tank that is configured above the toilet bowl, so that the fragrance is sprayed into the water that descends therefrom; in such circumstances, the apparatus is mounted on the rim of the water tank.

[0074] Although, for purposes of the present disclosure, a toilet bowl is used, it is understood that the apparatus and methods described herein may be applied to any plumbing or liquid-containing device (e.g., sink, basin, barrel, bidet).

[0075] Sensors and Methods of Actuation. Although specific types of mechanical actuation are described in detail herein, the apparatus of the present disclosure may be implemented with various actuation methods. These include: sensor-based actuation based on motion detection (e.g., detecting when a user sits on the toilet seat), based on light detection (e.g., detecting a change in light resulting from the user sitting on the toilet seat); chemical detection of hydrogen sulfide or another molecule associated with feces, etc. Other similar sensors may include, without limitation, motion, odor, noise, water flow, heat source, thermal signature, volumetric, pressure, gas composition, humanbioelectric signatures, and air quality parameters. The sensors may also be one or more of the following: proximity, infra-red, temperature / thermal signature, humidity, general motion, noise sensors; pressure / weight, gas / chemical composition, capacitive, ultrasonic sensors; optical (camera-based with privacy safeguards), radar, LIDAR, light level sensors; air pressure, vibration, accelerometer, gyroscope, electromagnetic, bioelectric sensors; biometric, airflow velocity, ultraviolet sensors; gas detection sensors for carbon dioxide, ammonia, hydrogen sulfide, methane; volatile organic compounds (VOCs), particulate matter sensors; or any applicable user detection sensors.

[0076] In addition, although in the detailed configurations described below, the pumping of the oil from the reservoir to the nozzle is purely mechanical, functioning via air displacement, in other embodiments, the pumping may be partially or entirely utilizing a mechanical or electric pump. In the specific embodiments described herein, the actuation is accomplished by depressing an actuator with a hand or by sitting on it. Actuation may also be performed using a push button, foot pedal, or mechanical lever. Actuation may also take place via remote control (e.g., via a remote connection to a mobile device, voice command, gesture, proximity-based triggering based on RFID / NFC / Bluetooth, etc.).

[0077] Integration with Bathroom. In the basic configurations described below, the device is a standalone device, not integrated with bathroom infrastructure. In alternative embodiments featuring connectivity to other devices, the same devices may be integrated with bathroom infrastructure (light switches, exhaust fans, door sensors, etc.) or with smart toilet infrastructure (e.g., electronically activated flush) and the initiation of any such infrastructure may automatically trigger spraying of oils from the apparatus into the toilet.

[0078] Materials. Any suitable materials may be used for the apparatus described herein. The apparatus may be made, for example, of metal, plastic, or a combination thereof. The apparatus may be manufactured through molding, additive manufacturing, or any combination thereof.

[0079] First Embodiment

[0080] Figs. 1-8 illustrate a first embodiment of an apparatus 20 for automated mechanical dispensing of fragrance into a toilet bowl. Unless specifically contradicted by what follows, all elements of the foregoing description (ingredients of the fragrance, actuation mechanisms, etc.) may be integrated into the apparatus 20 of the first embodiment.However, for purposes of achieving the advantages of the disclosed embodiments, certain mounting mechanisms and actuation mechanisms are particularly relevant, and will be discussed further herein.

[0081] Apparatus 20 includes a body 1 which contains a reservoir, and may further include a cover 2. In some embodiments, the cover is welded onto the body 1, thus rendering apparatus 20 single-use. In other embodiments, the cover 2 may be removably attached from the body (e.g., with a snap-fit connection, or through the use of fasteners or screws), thereby permitting removal and replacement, or refilling, of the reservoir. The reservoir may be soft-sided and deformable in response to pressure. The body 1 or cover 2 may include a visual indicator (e.g., a cutout or window) showing reservoir level, dispensing status, or activation confirmation.

[0082] A soft actuation button 3 is built within the cover 2. When button 3 is depressed, the reservoir may be compressed, thereby expelling fluid from the reservoir to a fluid conduit which is accessed from a bottom of the reservoir. The internal mechanism may include mechanical pressure amplification, which enables minimal force for activation and enables users with limited hand strength or mobility

[0083] Apparatus 20 further includes an adjustable mounting mechanism for securing the apparatus 20 to a rim of a toilet bowl. The adjustable mounting mechanism may include vertical and horizontal adjustment capabilities, and ensures that the apparatus hangs in a firm, stable position even when pressure is applied to the at least one mechanical actuator. In the illustrated embodiment, the mounting mechanism includes horizontal arm 5 and vertical arm 6. Horizontal arm 5 may include ridges, and the vertical arm 6 may include a latch that may be fixed at each of the ridges. This enables the vertical arm to be configured flush against an inner face of the toilet bowl. Any other ratcheting or tracking mechanism for the vertical arm may similarly be used.

[0084] Apparatus 20 may likewise include an adjustable mounting mechanism with respect to the vertical arm. In the illustrated embodiment, the vertical arm 6 includes ridges, and may include a vertical location lock 7 that may similarly be slotted into these different ridges. Adjustment of the vertical arm 6 relative to the horizontal arm 5, and of the vertical location lock 7 relative to the vertical arm, enables a tight fit between apparatus 20 and the rim of the toilet bowl. The mounting mechanism may include shock-absorbing or vibration-dampening elements to maintain stability during toilet usage. The mounting mechanism may likewise utilize non-permanent, non-damaging attachment methods suchas tension grips, silicone pads, or adjustable clamps (for example, at the bottom of the fluid conduit, or between the reservoir and the side of the toilet bowl, that do not require drilling or permanent modifications to the toilet. Other mounting elements, such as those utilizing snap-fit, springs, or elastics, are also possible, whether in lieu of the foregoing elements or in addition thereto.

[0085] Apparatus 20 further includes a soft upper button 8. The soft upper button 8 is located along the extent of the horizontal arm 5. When installed, the upper button 8 is arranged between the toilet bowl rim and the toilet seat. As a result, when the user sits on the toilet seat, he depresses the soft upper button 8. The soft upper button 8 is preferably designed with a suitably low profile so as to prevent interference with the toilet seat and maintain comfort for the user. The height is designed such that merely lowering the toilet seat does not cause actuation of the soft upper button 8, but sitting on the toilet seat introduces additional pressure which causes actuation of the soft upper button.

[0086] Referring to Fig. 2, fluid conduit 9 emerges from the bottom of the reservoir, rises along the side of the reservoir at an interior face thereof, proceeds beneath the horizontal arm 5 and through the vertical arm 6, and emerges at nozzle 10. Nozzle 10 is shown as dispensing the fluid substantially downward. Optionally, the nozzle may be configured with an adjustable dispensing angle mechanism which allows users to direct the spray or dispensing pattern to target specific areas within the toilet bowl. Optionally, the nozzle is configured to prevent backflow or clogging through the use of one-way valves, selfcleaning mechanisms, or anti-clog geometries.

[0087] The fluid may be delivered into the fluid conduit 9 through one of two mechanisms - depression of the soft button 3, which compresses the reservoir downward, and depression of upper button 8, which forces air downward through conduit 4, thereby pushing fluid through conduit 9. The mechanisms may operate through air displacement, meaning that actuation is accomplished by pressurizing the fluid conduit. The dispensing of the fragrance creates a vacuum, enabling air from the ambient atmosphere to enter via the nozzle. This air is then removed from the fluid conduit as additional fragrance is pushed into the conduit.

[0088] The dispersion of the fluid from nozzle 10 may proceed through any suitable mechanism. Purely mechanical mechanisms may include spraying, dispensing, dripping, or vapor release mechanisms. There also may be controlled chemical reactions that include, for example, foam or dissolvable capsules. Electronic mechanisms (not used inthe embodiment of Fig. 2) may include atomization, nebulization, electrospraying, or ultrasonic dispersion. The dose that is delivered may be metered or have a controlled release.

[0089] Figs. 3 and 4 depict additional views of apparatus 20 of FIGS. 1 and 2. In the view of Figs. 3 and 4, the apparatus 20 (including the reservoir 1, the arms 5 and 6, and the vertical location lock 7) are made of molded plastic. Also apparent in the view of Figs. 3 and 4 is that the nozzle 10 is configured substantially below the extent of the horizontal arm, thus ensuring that the oil is sprayed downward into the toilet bowl. The nozzle may include a swirl chamber to ensure proper mixing and spraying.

[0090] Figs. 5-8 depict apparatus 20 mounted on a toilet bowl 30. As can be seen, the arms 5, 6 and the vertical location locker 7 are positioned so as to securely lock the apparatus 20 on the rim of the toilet bowl 30. The upper button 8 is positioned over the rim of the toilet bowl 30, while the side button 3 is positioned at a location adjacent to the hand of a user that is sitting on the toilet seat.

[0091] FIGS. 9 and 10 depict depression of each of the actuators. In FIG. 9, the top actuator 8 is depressed, and in FIG. 10, the side actuator 3 is depressed.

[0092] Second Embodiment

[0093] FIGS. 11-20 depict a second embodiment of the dispenser 100. Dispenser 100 is similar to dispenser 20 in certain aspects, and in particular shares all of the technical aspects described above in connection with Fig. 1.

[0094] Referring to FIG. 11, apparatus 100 includes actuator 102 and vessel 108, both of which are configured to be situated outside the toilet bowl. In the illustrated embodiment, actuator 102 is a piston. Support 104 is substantially U-shaped. Support 104 is configured to be seated on the rim of the toilet bowl. Support 104 may be made of a malleable metal (e.g. aluminum) or plastic material that may be bent to securely fix apparatus 100 on the toilet bowl rim. In addition or in the alternative, the apparatus 100 may be structured in such a way that the apparatus balances over the rim of the toilet bowl, with vessel 110 containing a ballast weight corresponding to the weight of the fragrant oil in vessel 108. This ensures that the apparatus 100 stays in place, even without a tight connection.

[0095] Vessel 108 may contain a cartridge with a fragrance, as described above. The cartridge may be single use or may be replaceable or refillable (via opening of fill cap 112).
