Figure 7D illustrates an exemplary embodiment of the female fitment 42 in the slot 141 of the door 140. Figures 7E and 7F illustrate exemplary embodiments of the male fitment 40 interacting with the female fitment 42. In Fig. 7E, the female fitment 42 is located in the slot 141 in the door 140. As the door 140 is closed towards the housing 65, the tip 11 of the male fitment 40 comes into contact with the female fitment 42. The female fitment 42 may slide upwards in the slot 141 to provide a better engaging angle with the male fitment 40. Figure 7F is an exemplary illustration of the male fitment 40 and the female fitment 42 engaged to provide fluid communication between the removable reservoir 30 and the dispenser 25.

As one skilled in the art will appreciate, configuration of the male fitment and female fitment may vary due to a number of factors, including, but not limited to, size of the fitments, angle of rotation of male fitment, length of slot adapted to receive female fitment, etc.

In one embodiment, the fluid connection between the dispenser 25 and the removable reservoir 30 comprises tubing configured to allow the benefit composition to be transported from the removable reservoir 30 to the dispenser 25. One exemplary tubing comprises a polymeric tubing with one or more channels or conduits. In one embodiment, the tubing is configured to

Other exemplary materials of construction include aluminum foil. In one embodiment, the removable reservoir 30 comprises multiple layers of one or more materials. In another embodiment, the removable reservoir 30 comprises a single or multiple layer barrier film.

The dispenser 25 may comprise at least one nozzle for the purpose of distributing the benefit composition into the fabric article drying appliance. Misting/atomizing of the benefit composition can be achieved using any suitable spraying device such as a hydraulic nozzle, sonic nebulizer, pressure swirl atomizers, high pressure fog nozzle or the like to deliver target particle size. Non-limiting examples of suitable nozzles include nozzles commercially available from Spray Systems, Inc. of Pomona, California under the Model Nos. 850, 1050, 1250, 1450 and 1650. Another suitable example of a nozzle is a pressure swirl atomizing nozzle made by Seaquist Perfect Dispensing of Cary, Illinois under Model No. DU-3813. In one exemplary embodiment, as illustrated in Fig. 2, the fabric article treating device 20 further comprises a fluid handling system 55, a power source 50 and a controller 60. In one exemplary embodiment, the fluid handling system 55 is configured to transport the benefit composition from the removable reservoir 30 to the dispenser 25. The dispenser 25 is configured to deliver the benefit composition to one or more fabric articles in the fabric article drying appliance. The power source 50 is configured to provide electrical power as needed by the fluid article treating device, such as the controller 60, the fluid handling system 55, sensors, and any electrical needs of a user interface. The controller 60 is configured to regulate the dispensing of the benefit composition. For example, the controller 60 may determine the optimum condition to dispense the benefit composition, the quantity of benefit composition to be dispensed and the rate at which to

dispense the benefit composition. In one embodiment, the fabric article treating device further comprises a communication link adapted to provide communication between the controller of the fabric article treating device and the fabric article drying appliance. For example, the controller may send and/or receive signals to/from the fabric article drying appliance to determine the optimum benefit composition dispensing conditions such as, time, length, etc.

Another exemplary embodiment of the present invention is illustrated in Fig. 3. In this exemplary embodiment, the housing 65 is adapted to receive various components in addition to the removable reservoir 30. Optionally, the housing may substantially enclose and protect the components in their assembled form. For example, as shown in Fig. 3, the housing 65 may receive the power source 50, the fluid handling system 55, the controller 60 and the removable reservoir 30. In another embodiment, the housing 65 may comprise a tubing storage area adapted to contain a quantity of fluid line 32 to allow the user to customize the installation of the fabric article treating device for the user's particular fabric article drying appliance. The housing 65 may be constructed with any materials known to one skilled in the art. Exemplary materials include but are not limited to polymers, plastics, ceramics, metals, fabric, wood, and the like.

In one exemplary embodiment as illustrated in Figure 4, the male fitment 40 has a tip 11, orifices 12 for fluid flow, an o-ring 13 for sealing the fitment in engagement with the fitment 42, an axis of rotation 14 and a seating lip 15. The female fitment 42 comprises slots 43 for gripping and positioning, a seal chamber 47 and a removable plug seal 48. The plug seal 48 is seated in the seal chamber 47 in the closed position in Figure 4. In one exemplary embodiment, the distance 34 between the axis of rotation 14 and the seating lip 15 is between about 30 and about 40 mm, and in an alternative embodiment, the distance is about 34 mm. Figure 5 shows the female fitment 42 in the open position with plug seal 48 removed from the seal chamber. In one embodiment, the plug seal 48 has a lower edge 49. In another exemplary embodiment, the tip 11 of the male member 40 is adapted to click fit inside the plug seal 48 at the top portion 53 of the plug seal.

In one exemplary embodiment of the present invention as illustrated in Figure 4, the male fitment 40 and the female fitment 42 are configured such that during the engaging process, the o- ring 13 of the male fitment 40 is positioned inside the bottom of the seal chamber 47 of the female fitment 42.

In another exemplary embodiment, the tip 11 of the male fitment 40 enters the plug seal 48 of the female fitment 42 without touching the lower end of the plug seal 48 and then connects securely with a click fit at the top of the plug seal 48. The plug seal 48 is configured to only open

when the tip 11 of the male fitment is securely attached to the female plug seal 48. In this embodiment, the female fitment is configured such that when the male fitment is disengaged from the female fitment, the plug seal 48 is biased to re-close and form a seal in the seal chamber 47.

In one exemplary embodiment as illustrated in Fig. 8, the fluid handling system 55 comprises a pump 70. The pump 70 is in communication with the removable reservoir 30 and the dispenser 25 via fluid lines 72 and 74, respectively. The pump 70 is configured to transport benefit composition from the removable reservoir 30 to the dispenser 25 for dispensing of the benefit composition. In one embodiment, the pump 70 comprises a piezo-electric pump. In another embodiment, the pump 70 may comprise a diaphragm pump. As one skilled in the art will appreciate any pump known to one skilled in the art may be utilized to transport the benefit composition from the removable reservoir 30 to the dispenser 25. Other exemplary pumps include piston pumps, gear pumps, peristaltic pumps, and bellows-type pumps.

As noted above, one type of pump 70 that can be used in the present invention is a piezoelectric pump. While a piezo-electric pump has certain membranes or laminations which may vibrate in a reciprocating- type fashion, the piezo-electric pumps generally do not have major moving parts, such as rotating shaft and bearings used with a rotator member to displace a fluid or gaseous fluid, that experience wear over time. One commercially available suitable piezoelectric pump usable in the present invention is manufactured by PAR Technologies, LLC, located in Hampton, Virginia, and marketed as the "LPD-Series" laminated piezo-electric fluid pumps. Pumps which draw a relevantly low current are particularly suitable in certain embodiments.

In another embodiment, the removable reservoir 30 may be positioned in such a way to provide gravitation flow of the benefit composition to the dispenser 25. For example, the removable reservoir 30 may be mounted above the fabric article drying appliance to create static head on the benefit composition to allow dispensing of the benefit composition without the utilization of a pump.

Another exemplary embodiment of the present invention is illustrated in Fig. 9. In this embodiment, as in previously discussed embodiments, the fabric article treating device 20 comprises a dispenser 25 adapted for location inside of a fabric article drying appliance and an removable reservoir 30 adapted for location outside of the fabric article drying appliance. The dispenser 25 and the removable reservoir 30 are adapted for fluid communication with one another. The removable reservoir 30 contains a benefit composition. The device further comprises a controller 60 in electrical communication with a sensor 75. In one exemplary

embodiment, the sensor comprises a temperature sensor. In another exemplary embodiment, the sensor 75 comprises a light sensor. In yet another exemplary embodiment, the sensor 75 comprises a motion sensor. The controller 60 is adapted to send and/or receive signals from the sensor 75 and to determine the dispensing conditions for dispensing the benefit composition.

Optionally, filters and/or filtering techniques can be used to filter the benefit composition, if desired, for example at a point between the reservoir 30 and the outlet of the dispenser 25. Non-limiting examples of this include: utilizing a filter in the dispenser 25 prior to dispensing of the benefit compositions. Alternatively, the benefit composition may be filtered prior to dispensing into the reservoir; or a combination of filtering techniques may be employed.

The dispenser 25 and the removable reservoir 30 are adapted for fluid communication with one another. In one embodiment, the dispenser 25 and the removable reservoir 30 may be in electrical connection to one another. Non-limiting examples of connecting the dispenser 25 and the removable reservoir 30 may include utilizing a flat cable (also referred to as a ribbon cable), a wire, a wire or group of wires enclosed in a stealth of woven or nonwoven material, a conduit (a non-limiting example of which is a conduit for the benefit composition), or combination thereof. The woven or nonwoven sheet may be used as a method of attaching the dispenser 25 and the removable reservoir 30. The dispenser 25 and the removable reservoir 30 may be used to provide a means of gravitational counterbalancing so as to reduce unnecessary tension on the wires and/or the connections.

The power source 50 may comprise chemical batteries, or any electrical power source, including standard household line voltage, or even solar power. Batteries may be utilized, and are particularly suitable when the fabric article treating device 20 is in the form of an add-on device for an existing fabric article drying appliance 35. However, any appropriate power adapter can be provided to convert an AC power source to the appropriate DC voltages used in any electrical components of the fabric article treating device 20, such as in the fluid handling system 55, the controller 60, and any sensors 75. The power source 50 may also comprise any mechanical power source used to store potential energy. Non-limiting examples include; springs, weights, compressed gases, etc.

As noted, the fabric article treating device 20 can include optional sensors 75. Non- limiting examples of optional sensors include a door (or lid sensor), a motion sensor, a humidity sensor, and/or a temperature sensor. One non-limiting example of a door/lid sensor is an optoelectronic device, such as an optocoupler or an optical input sensor, e.g., a phototransistor or photodiode. When the door/lid of the drying appliance is open, the door sensor will change state,

and will output a different voltage or current level along an electrical conductor that leads from the door sensor back to the controller. This can be used as a safety device to immediately interrupt the dispensing of the benefit composition from the dispenser 25. The optional door sensor could be utilized even when a control system is integrated into the overall conventional control system of the drying appliance. For example, a drying appliance typically has its own door sensor which shuts off the rotating drum of the dryer when the door becomes open. In this instant, the optional door sensor can act as a backup or second door sensor to the dryer's internal original sensor that shuts off the rotating drum. One example which could be used as a door/lid sensor is an NPN Phototransistor, Part No. PNA1801L, manufactured by Panasonic, of Osaka, Japan. In another embodiment, a communication link could be established between the drying appliance and the controller, wherein the drying appliance would send the controller a signal relating to the operational state of the drying appliance (e.g., door open/closed, drying cycle, temperature, etc.).

Another type of optional sensor 75 that can be utilized by the fabric article treating device 20 of the present invention is a motion sensor. For fabric article drying appliances 35 which utilize a moving interior, such as a rotating drum, the motion sensor can detect if a fabric article drying appliance is in use. One example of a motion sensor is a vibration and movement sensing switch manufactured by ASSEM Tech Europe Ltd., of Clifton, New Jersey, available as Model No. CW1600-3. Another type of optional motion sensor that may be used in the present invention uses a light source to direct (infrared) light at a surface, and the relevant motion of that surface can be detected by the intensity and/or frequency of the returning light. Such sensors can measure the actual speed of rotation, if that information is desired.

Another optional sensor 75 that can be used in a fabric article treating device 20 of the present invention is a humidity sensor. The optional humidity sensor, together with the controller, may be used to control the amount of composition being dispensed by the dispenser 25, and also may be utilized to determine the proper environmental conditions during an operational cycle in which the dispensing event should take place. Additionally, this humidity sensor may be used to maintain a specific humidity by controlling the dispensing the benefit composition such that optimal de-wrinkling and/or other benefits are achieved. Many different types of humidity sensors could be used in conjunction with the present invention, including variable conductivity sensors. One such sensor is manufactured by Honeywell, of Freeport, Illinois under the Model No. HIH-3610-001, although any of the HIH-3610 series may be used.

A further optional sensor 75 that can be useful in the fabric article treating device 20 of the present invention is a temperature sensor, such as one that outputs an analog or digital signal along the electrical conductor that leads back to the controller.

As noted above, the fabric article treating device 20 may comprise a controller 60. In one embodiment, the controller may be a microcontroller. A suitable microcontroller is manufactured by Microchip, of Chandler, Arizona under the Part No. PIC16LS876-04/P. However, other microcontrollers made by different manufacturers could also easily be used. In one exemplary embodiment, the microcontroller includes on-board random access memory (RAM), on-board read only memory (ROM), which comprises electrically programmable non-volatile memory elements, as well as on-board input and output lines for analog and digital signals. The controller may also be used with a crystal clock oscillator, although a RC circuit could be used instead as a clock circuit, if desired. The clock circuit provides the timing of the clock as necessary to operate the controller. In one embodiment, the controller comprises a port that can be interfaced to an optional programmable interface using a communication link, such as RS-232 communication link. The port allows a user to alter the program information of the controller, such as dispensing options, etc.

One skilled in the art will appreciate that the controller can be any type of microprocessor or microcontroller circuit commercially available, either with or without on-board RAM, ROM, or digital and analog input/output (I/O). Moreover, a sequential processor may be used to control the fabric article treating device 20, or alternatively a parallel processor architecture or a logic state machine architecture could be used. Furthermore, the controller 60 may be integrated into an Application Specific Integrated Circuit (ASIC) containing many other logic elements that could be used for various functions, as desired, such functions being optional depending upon the model of the fabric article treating device 20 that will be sold to a consumer. To change model features, the manufacturer need only program the ASIC or the on-board RAM of the controller according to the special parameters of that particular model, while using the same hardware for each of the units.

It will also be understood that discrete digital logic could be used instead of any type of microprocessor microcontroller unit, or analog control circuitry could be used along with voltage comparators and analog timers, to control the timing events and to make decisions based on input levels of the various sensors that are provided with the fabric article treating device 20.

It will be understood that the present invention can be readily used in other types of fabric article drying appliances, and is not limited solely to clothes "dryers". In the context of

this patent document, the terms "dryer" or "drying apparatus" or "fabric article drying appliance" include apparatuses that may or may not perform a true drying function, but may involve treating fabric without attempting to literally dry the fabric itself. As noted above, the terms "dryer" or "drying apparatus" or "fabric article drying appliance" may include a "dry cleaning" process or apparatus, which may or may not literally involve a step of drying. The term "fabric article drying appliance" as used herein, also refers to any fabric treating apparatus that utilizes moving air directed upon one or more fabric articles, a non-limiting example of which includes a clothes dryer, and modifications thereof. Such apparatuses include both domestic and commercial drying units used in dwellings, laundromats, hotels, and/or industrial settings. In addition, it should be noted that some drying appliances include a drying chamber (or "drum") that does not literally move or rotate while the drying appliance is operating in the drying cycle. Some such dryers use moving air that passes through the drying chamber, and the chamber does not move while the drying cycle occurs. Such an example dryer has a door or other type of access cover that allows a person to insert the clothing to be dried into the chamber. In many cases, the person hangs the clothes on some type of upper rod within the drying chamber. Once that has been done, the door (or access cover) is closed, and the dryer can begin its drying function. Dispensing of a benefit composition can take place within such a unit, however, care should be taken to ensure that the benefit composition becomes well dispersed within the drying chamber, so that certain fabric items do not receive a very large concentration of the benefit composition while other fabric items receive very little of the benefit composition.
