Abstract
The present invention comprises a system and method for unclogging drains, piping systems and related items. The system employs an aerosol delivery of a broadly dispersed compressed gas wave. Preferably, the gas comprises the liquefied propellant Tetrafluoroethane that freezes the clog, allowing for more efficient break up of the clog. Solvents, fluid coatings and fragrance may also be employed to further improve the efficiency of the system. Additionally, an extension and/or adapter may also be employed, thereby providing a single system capable of unclogging drains and associated systems of almost any size or type.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/791,342, filed Apr. 12, 2006.
- 1. Field of the Invention
- The present invention relates generally to the field of plumbing devices and more particularly to an aerosol drain opener.
- 2. Description of the Related Art
- Many piping systems and similar plumbing configurations include drains of some type. Drains are known generally in the art as any type of pipe or similar conduit whereby a liquid may be drawn off. It is a generally common occurrence for these drains to become clogged over time, either partially or completely, in a manner that reduces their effectiveness. Not surprisingly, those skilled in the art have devised a number of approaches to alleviate this problem.
- There are a variety of methods used to combat drainage problems. One solution includes the introduction of a force designed to push or pull clogged material out of a drain and nearby areas. This may be accomplished via manual plunging devices, or other means of introducing a pressurized force. Other methods include means for dissolving the clogging material, such as hot water, vinegar and sodium bicarbonate solutions, as well as various chemicals.
- In general, the use of compressed gas for unclogging drains is known. For example, professional plumbers have used compressed gas canisters as a means for delivering a burst of compressed air against a clog, thereby dislodging it.
- This concept was adapted for the home market by the introductions of aerosol clog removers. It has been believed that a narrowly directed stream of gas is preferred for creating a breach in a clog, thereby enabling a subsequently delivered stream of water or other solvents, to progressively dilate the clog until at least the majority of the clog has been dislodged.
- For example,
FIG. 1 depicts a prior art solution in an aerosol can 10 having a drain interface cap 2 and adrain mating member 4. Themating member 4 is provided with anorifice 6 in fluid communication with agas conduit 8 in the interface cap and with a conventional aerosol can valve (not illustrated). The valve is opened by compression between the interface cap and the aerosol can. In keeping with the prior art approach of delivering a narrowly focused jet of compressed gas, the diameter of the orifice is relatively narrow. As illustrated, the prior art diameter d is approximately 0.75 inch (roughly 2 cm). - Many sinks found in the home are provided with stopper mechanisms that are raised and lowered in a drain opening by use of a lever disposed in the drain itself. It is readily apparent that the prior art aerosol drain opening system shown in
FIG. 1 cannot be used within such drains without at least partial disassembly of the stopper mechanism. Many homeowners do not want to perform this step due to difficulties in reinserting the stopper mechanism, and due to the tendency for such lever mechanisms to become coated with grime and other waste. Additionally, homeowners will often either fail to reinsert the stopper mechanism properly, or may even damage it beyond repair. - It is also apparent that the prior art approach is not suitable for use with larger drain openings, such as typically found with floor drains and toilets.
- It has been found that the initial application of compressed gas only partially interrupts some clogs, thereby requiring the use of solvents, water, etc. to further clear the clog. Therefore, a more effective technique for enabling clog removal using aerosols is needed, in addition to one that is readily adapted for use with a variety of drain configurations.
- Therefore, it is an object of the present invention to provide a system for unclogging and otherwise clearing drains using aerosols to effectively clear clogs.
- It is also an object of the present invention provide a system that uses aerosols for clearing drains and associated systems that is readily adaptable for use with a variety of drain configurations.
- The present invention provides an improved system and method for using aerosols to effectively clear clogs in conduits such as drain pipes. As used in this application, the term “aerosol(s)” is used in its broadest sense to include any type of matter, solid, liquid or gas, typically contained within a releasably sealed container. Additionally, “aerosol” may mean: “of or containing a substance, such as a liquid or gas, under pressure for dispensing.” Also, when used in this application, the term “gas” refers to any type of gaseous substance, at any temperature, and may include substances that may or may not be in gaseous form at room temperature, and may or may not be inert, or active.
- As opposed to the narrowly focused jet of compressed gas found in the prior art, the present invention recognizes and benefits from the superior drain clearing capability resulting from a broadly dispersed compressed gas wave. The term “wave” refers to a form or shape that a gas may take, wherein the gas is not a narrowly focused jet. When impacted by such a gas wave, the entire surface of a clog is contacted and dislocated. Water may then be used merely to translate the disrupted clog out of the pipe, rather than being used to continue the clog removal begun by the prior art.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description, appended claims and accompanying drawings where:

FIG. 16A-16F illustrate the present invention employed in various drain configurations. - As previously mentioned,
FIG. 1 illustrates a well-known prior art device. -
FIG. 2 represents a perspective view of a preferred embodiment of the present invention. InFIG. 2 , anaerosol delivery device 20 is provided with adrain interface cap 22 having a uniquedrain mating member 24. Theaerosol delivery device 20 may comprise an aerosol spray can or similar item. Also shown isorifice 26 formed in themating member 24, saidorifice 26 having a diameter d′. Diameter d′ comprises a diameter that is approximately 1.75 inches (roughly 4.4 cm), which is substantially larger than that of the prior art. This configuration thus forms agas dispersion region 30 within themating member 24 and thedrain interface 22; thedispersion region 30 being in fluid communication withgas conduit 28, connected to an aerosol can valve. -
FIGS. 3 and 4 provide alternate views of theaerosol delivery device 20 having the presently discloseddrain interface cap 22 with thedrain mating member 24 installed therein. - A key feature of the present invention that distinguishes it from the prior art corresponds to the delivery of the gas used to unclog a drain. By relying on a narrow jet of gas the prior art teaches away from the unique features of the present invention. Rather than utilize a typical compressed gas (ex. compressed air, CO2, nitrogen), the present invention incorporates a substantially uniform wave of high pressure gas, derived from the use of a liquefied propellant, preferably tetrafluoroethane. Tetrafluoroethane maintains a constant pressure (whether the can is full or partially full), unlike other compressed gases, and when emitted is extremely cold. Further, it is non-flammable and contains no CFCs, thus causing no harm to sound pipes or the environment. In addition to enabling a substantially uniform high pressure wave of gas to be applied across the surface of a clog, a cutting agent such as dimethylketone is preferably employed for delivery with the gas. Tetrafluoroethane is used to instantly freeze the clog upon impact, rendering the clog more prone to fracturing and being displaced as larger pieces, resulting in a more immediate opening of the pipe or drain. Of course, the temperature of the clog rises after displacement, after which the displaced pieces of the clog are prone to dispersal. Dimethylketone is a solvent which aids in the removal of residual portions of the clog and the dispersal of the dislocated pieces.
- Preferably a fragrance is also provided for application with the gas. Odors associated with rotting or degrading material comprising or beyond the clog are thus masked.
- In a further embodiment, another fluid is included in the contents of the aerosol can which acts to coat the interior of the drain pipe with a smooth, non-toxic coating. Such a material assists in retarding the buildup of clogging materials and facilitates future clog dislodgement. In one embodiment this material is a silicone-like product.

FIGS. 5 and 6 illustrate thedrain interface cap 22 of the present invention. Thedrain interface cap 22 is preferably formed of molded plastic or copolymer polypropylene, which is resistant to the effects of the propelled solvent. The material is also sufficiently pliable to resist cracking with rough use, is light-weight, and is non-porous so as to prevent the absorption of odors and/or other materials, such as bacteria, fecal matter, etc., associated with clogged sinks or toilets. -
FIGS. 7 and 8 illustrate thedrain mating member 24 which is normally disposed within thedrain interface cap 22. Thedrain mating member 24 is preferably formed of a resilient material such as rubber or clear gloss flexible vinyl, with a density selected to minimize the risk of scratching or otherwise marring a surface adjacent a treated drain, or to the drain itself. The pliable nature of the material also enables thedrain mating member 24 to conform to a degree to irregular surface features to provide a tighter seal for maximum effectiveness and to avoid the risk of slipping out of position during delivery. The interior diameter ofdrain interface cap 22 anddrain mating member 24 are selected to form a gas dispersion region 30 (SeeFIGS. 2 and 3 ) which enables the compressed gas to disperse, and for pressure to equalize prior to impacting the clog. - Another benefit associated with the configuration of the
drain interface cap 22 anddrain mating member 24 is that they can be used with drains having pop-up type stopper mechanisms without the need for removing the mechanism. For example, the selectedgas dispersion region 30 diameter will accommodate most commonly encountered bathroom and bathtub drain stoppers. -

Theadapter 34 includes an adapter mating member 42 having an outer dimension d″ that is substantially identical to the inner diameter d′ of thedrain mating member 24. Aninner sealing ring 36 and anouter sealing ring 38 provide lower mating surfaces that are substantially coplanar in a preferred embodiment. For drains of a diameter substantially the same as that of theinner sealing ring 36, compressed gas is delivered in substantially the same manner as with thedrain mating member 24 alone. This is due to the fact that the space within the inner ring serves as an extension of thegas dispersion region 30. - For drains that have a diameter greater than that of the
inner sealing ring 36 but less than that ofouter sealing ring 38, theouter sealing ring 38 serves to enable the application of the compressed gas to the clog with only a small decrease in total pressure due to the region between the inner and outer sealing rings 36 and 38 being in fluid communication with the gas flow path. The shallow angle of theouter surface 40 ofadapter 34 with respect to a horizontal plane helps minimize this pressure decrease in a preferred embodiment. - In addition to the configurations illustrated in
FIGS. 11 and 12 , theadapter 34 can also be configured to receive thedrain interface cap 22, with or without thedrain mating member 24, inserted within theinner sealing ring 36. In this manner, the adapter mating member 42 can be inserted into an orifice such as within a toilet bowl, theouter surface 40 of the adapter acting as a sealing interface to the bowl itself. - The
adapter 34 is preferably provided of clear gloss flexible vinyl, with a specifically selected density that allows for superior pliability and conformance in a preferred embodiment. The pliability of this material is preferred for its enhanced conforming capabilities, while still being non-porous and thus resistant to odor, liquid, bacteria and fecal matter absorption. Plurality oftrusses 44 are preferably employed intermediate theinner sealing ring 36 and the underside of the adapterouter surface 40 to resist vertical deformation of theouter surface 40. -
FIGS. 13 through 15 illustrate an additional element,extension 50, of the present invention in an alternate embodiment.Extension 50 is useful in a variety of situations; including clogged toilets or clogged drains that are not readily accessible by hand, or that are under an accumulation of water or other substance. Theextension 50 preferably includes ahandle 52 at the proximal end ofextension 50, which may include finger indentations or similar additions including non-slip material to form an improved grip. At the distal end, a receptacle 54 is formed as a substantially open cylinder. The diameter of the receptacle 54 is preferably slightly greater than that of theaerosol delivery device 20. Preferably, the inner surface of the receptacle 54 is provided with a plurality ofribs 56, preferably three or more, that may extend slightly into the receptacle 54, and which may engage the outer surface ofaerosol delivery device 20 once inserted into the receptacle 54. The plurality ofribs 56 act to prevent theaerosol delivery device 20 from becoming disengaged fromextension 50 once inverted. Additional ribs may be formed on the bottom interior surface of receptacle 54 to prevent anaerosol delivery device 20 comprising a concave bottom from becoming vacuum adhered to the bottom interior surface of receptacle 54. An air release in the form of an air hole may be provided in the bottom surface of the receptacle 54 in an alternate embodiment to enable air to enter and exit the receptacle 54 as theaerosol delivery device 20 is remove or inserted. - Preferably, the
extension 50 is formed of a semi-rigid material such as molded plastic or copolymer polypropylene. The selected material is chosen to resist odor and liquid retention. Structural ribs may be provided to increase the rigidity of theextension 50 without significantly increasing its weight or size. - While the presently disclosed system benefits from its flexibility in terms of adapting to various drain configurations, certain specific examples of use are illustrated in
FIGS. 16A through 16F as examples, not as limitation. For example, theaerosol delivery device 20 with thedrain interface cap 22 and thedrain mating member 24 may be sufficient for use with a single sink, double sink, garbage disposal, and bathtub, as seen inFIGS. 16A through 16D . For drains with an overflow drain or second interconnected drain, it may be necessary to apply a wet washcloth or drain plug to the other drain to maximize the pressure applied to the clog. - To operate in conjunction with a larger drain opening, such as that of a toilet, and as illustrated in
FIG. 16E , theadapter 34 may be installed on thedrain interface cap 22 in an inverted position with the adapter mating member 42 projecting into the toilet drain. It will be noted that this illustration depicts the optional use of theextension 50. Finally, for larger diameter drains such as floor drains, theadapter 34 is employed with the inner sealing rings 36 andouter sealing ring 38 facing the drain. Water may also be used to improve the seal between theadapter 34 and the floor surrounding the drain. - Together, the previously disclosed elements provide an adaptable system for effectively removing clogs from a variety of drains and/or other openings.
- Although the present invention has been described with reference to particular embodiments, it will be apparent to those skilled in the art that variations and modifications can be substituted therefore without departing from the principles and spirit of the invention.
