The technology described herein relates generally to the fields of candle wicks and candles and methods of making the same. More specifically, the technology relates to a method for extinguishing a candle at timed intervals using a combustible material consisting essentially of a wick designed with the ability to automatically and slowly self-extinguish a flame in equal-time intervals.
The purpose of a candle wick is to provide a candle with a flame. The heat from the flame melts the wax surrounding the base of the wick directly beneath it. The melted wax is then drawn up within the wick providing fuel for the flame. This ongoing cycle allows the candle to burn continuously. Wax in solid state is melted by the heat of the flame and converts to a liquid state. The liquid wax is drawn up to the top of the wick inside the flame and continues the burning process. The cycle repeats itself until the wick is no longer functioning due to lack of fuel for the flame.
Candles have been used for many years and for many different reasons; the reasons vary depending on the user. Today, a large number of candles are purchased simply for their pleasant fragrances and decorative appearance. The aromatherapy derived from a candle is widely used as well. It entices the user to relax and forget about everyday responsibilities.
However, one problem that exists between the user and the candle is that the user neglects to extinguish the candle. People today are simply too busy to remember to blow out a candle prior to leaving their homes. Panic sets in. A candle equipped with a wick that will automatically extinguish a candle flame in equal-time intervals would provide a user with the security of knowing that their candle will self extinguish in a short period of time.
Another problem that exists today is the vast number of house fires caused by leaving a candle unattended. The average burning time for a candle may be 60 to 95 hours. This time period is too long since it creates a greater risk of the candle being knocked over by a house pet, wind, or even a small child. Limiting the amount of burning time from one to four hours could significantly reduce the risk of house fires.

Therefore, a need exists for a timed wick and candle with these attributes and functionalities. The timed wick and candle according to embodiments of the invention substantially departs from the conventional concepts and designs of the prior art. It can be appreciated that there exists a continuing need for a new and improved timed wick and candle which can be used commercially. In this regard, the technology disclosed herein substantially fulfills these objectives.
The foregoing patent and other information reflect the state of the art of which the inventor is aware and are tendered with a view toward discharging the inventor's acknowledged duty of candor in disclosing information that may be pertinent to the patentability of the technology disclosed herein. It is respectfully stipulated, however, that the foregoing patent and other information do not teach or render obvious, singly or when considered in combination, the inventor's claimed invention.
In various exemplary embodiments, the technology described herein provides for a candle and a method for extinguishing a candle at timed intervals using a combustible material consisting essentially of a wick designed with the ability to automatically and slowly self-extinguish a flame in equal-time intervals.
In one exemplary embodiment, the technology described herein provides a method for extinguishing a candle at timed intervals using a combustible material. The method includes: utilizing a combustible composition adapted for application to a wick segment; utilizing a combustible first wick segment; coupling a combustible second wick segment to the combustible first wick segment; placing the combustible second wick segment adjacent to the first wick segment; and configuring the combustible second wick segment to, as the combustible first wick segment, once ignited, burns down to the combustible second wick segment, interrupt and slowly self-extinguish the burning of the first wick segment. The candle wick is configured to be relit, post extinguishment, without having to physically remove a non-combustible barrier.
The method also can include: configuring the combustible first wick segment to be a predetermined length, such that, based on a candle type, length, width, and size, in which the combustible first wick segment is placed, a known burn time is approximated at which point a burning of the combustible first wick segment reaches the combustible second wick segment and automatically and slowly self-extinguishes, thereby providing the self-extinguishing, timed-interval candle wick with automatic and slow self-extinguishment at a known, approximated time subsequent to a lighting of the combustible first wick segment.
The method further can include: utilizing a plurality of combustible first wick segments; and utilizing a plurality of combustible second wick segments and interspersing one combustible second wick segment between each two combustible first wick segments. The plurality of combustible first wick segments are of generally equal widths and lengths, thereby providing a regular time interval at which the candle wick is automatically and slowly self-extinguished each time the candle is lit.
The method also can include: varying the regular time interval by increasing or decreasing the lengths of the plurality of combustible first wick segments.
The method further can include: configuring the candle wick to be relit, post extinguishment, without having to physically remove a non-combustible barrier.
The method also can include: forming the combustible second wick segment by spirally wrapping the combustible composition around a heat set and subsequently interweaving with the combustible first wick segment at a predetermined location. The combustible composition can be an organic polymer. The organic polymer can be a fatty acid created through the hydrolysis of beef fat with caustic soda and potash. The organic polymer can be a malleable solid in the form of a bead that is placed upon a combustible first wick segment at a predetermined location. The bead can be spherical.
The method further can include: adding to the combustible composition an extinguishing agent additive to increase the material resistance to burn.

In yet another exemplary embodiment, the technology described herein provides a candle adapted for extinguishment at timed intervals using a combustible material. The candle includes: a polymeric base; a combustible first wick segment; and a combustible second wick segment adapted to be coupled adjacent to the combustible first wick segment. The combustible second wick segment is adapted to, as the combustible first wick segment, once ignited, burns down to the combustible second wick segment, interrupt and slowly self-extinguish the burning of the first wick segment. The candle wick is configured to be relit, post extinguishment, without having to physically remove a non-combustible barrier.
The candle also can include: a plurality of combustible first wick segments; and a plurality of combustible second wick segments interspersed one combustible second wick segment between each two combustible first wick segments. The plurality of combustible first wick segments are of generally equal widths and lengths, thereby providing a regular time interval at which the candle wick is automatically and slowly self-extinguished each time the candle is lit.
The combustible first wick segment is a predetermined length, such that, based on a candle type, length, width, and size, in which the combustible first wick segment is placed, a known burn time is approximated at which point a burning of the combustible first wick segment reaches the combustible second wick segment and automatically and slowly self-extinguishes, thereby providing the self-extinguishing, timed-interval candle wick with automatic and slow self-extinguishment at a known, approximated time subsequent to a lighting of the combustible first wick segment.
The polymeric base further can include an organic polymer having a fatty acid created through the hydrolysis of beef fat with caustic soda and potash. The organic polymer can be a malleable solid in the form of a bead that is placed upon a combustible wick segment at a predetermined location. The bead can be spherical.

Further advantageously, the technology described herein provides for numerous candle applications, including variations in size, style, interval timing, and extinguishment timing.
There has thus been outlined, rather broadly, the more important features of the technology in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the technology that will be described hereinafter and which will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the technology in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The technology described herein is capable of other embodiments and of being practiced and carried out in various ways.

As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the technology described herein.
Further objects and advantages of the technology described herein will be apparent from the following detailed description of a presently preferred embodiment which is illustrated schematically in the accompanying drawings.
The technology described herein is illustrated with reference to the various drawings, in which like reference numbers denote like device components and/or method steps, respectively, and in which:
Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides for a candle and a method for extinguishing a candle at timed intervals using a combustible material consisting essentially of a wick designed with the ability to automatically and slowly self-extinguish a flame in equal-time intervals.
Referring now to
The technology disclosed herein is directed to creating timed intervals within a candle such that upon completing an interval the candle automatically and slowly self-extinguishes, yet is able to be relit without having to physically remove a non-combustible barrier. Rather than physically removing a barrier, the barrier itself consists of a combustible material that upon additional heat, chemically changes, allowing continued burning of the candle. The combustible material acts to both initially extinguish the burning candle and then combusts to allow continued burning of the candle.
In one embodiment the timing mechanism consists of varied amounts of magnesium metal present throughout the wick segment. The varying amounts of magnesium physically changes the burning characteristics of a candle, resulting in the desired extinguishing with the ability to re-light at a later time, starting a new timed interval designed into the candle.
A second embodiment does not require complete treatment of the wick, but instead allows for the treatment of only the end of intervals within the candle body, positioning the timing mechanism on and around various wick segments. The positioning of the combustible substance is referred to as wick treatment, but is not limited to placing a substance on the wick segment, e.g. the combustible substance may be infused into the wick. Using the magnesium calls for incorporation of the substance within the wick, and various other embodiments may require a contribution from the additives or wax type contained within the candle not just the wick.
In both of these embodiments the end result is the use of a timing mechanism that causes a candle to self-extinguish at a predetermined time, while allowing to be relit at a later time, preserving a wick segment necessary for burning, and not requiring additional effort from an operator other than applying additional heat. (The additional effort refers to many of the methods in the prior art that facilitate this process with non-combustible materials that have to be either physically removed—or require a separate wick segment to be recovered from within the wax body.)
Depending on the embodiment a combination of wick type, wax, and additives may be used to determine an approximate burn time of a candle. Once having defined a candle's burn characteristics, a burn rate in length per time can be determined. A time interval can then be set by identifying a start and end position on the wick segment. For example, a cylindrical pillar consisting of a 1.5″ diameter and standing 2.5″ in height has been determined to have a total burn time of 10 hours. The relationship between candle height by total burn time dictates that the candle is burning 0.25 inches per hour. At this estimated rate, positioning a treated segment on the wick at 1.25″ from the top of the candle would provide two burn intervals of approximately 5 hours.
In an exemplary embodiment the timing mechanism is an organic polymeric substance possessing the burn characteristics described above. The organic polymer is created through the hydrolysis of beef fat with caustic soda and potash. The process is essentially a raw version of saponification that produces a substance consisting mainly of fatty acid (FA) and glycerol (with additional unreacted reactants or byproducts). The resulting FA is a malleable solid that can be physically applied to the wick segment at a predetermined length prior to forming the candle. The treated wick is then placed within the mold and the candle is created as is customary. The FA is placed on zinc core wicks and withstands temperatures of 140° F. Paraffin wax is poured in around this combination and hardens to form a votive candle. The amount of FA applied at the designated wick length is approximately 40-55 mg and effectively extinguishes the candle when the flame comes in contact with the FA.
As is common for solid combustibles, the FA burns more effectively when a sufficient specific area ratio is heated. For example, it is easier to start a fire by lighting smaller twigs than a large branch. Similarly, as the flame approaches the FA only a small portion (specifically the top) comes into contact with the flame—thus causing the candle to burnout. The placement of the FA effectively prevents the wicking process stopping the flow of fuel to the flame. Once extinguished, the user can then take a lighter and apply a flame directly to the FA for 5 to 10 seconds, providing enough heat to quench the specific area ratio requirement and reignite the candle. At this point the FA continues to burn away exposing more of the wick beneath and simultaneously relighting the candle wick. By burning away, the wicking process is once again continued and the heat produces by the combusting FA provides a sufficient melted wax pool for further combustion.
One process for creating the bead material is as follows:
Extract Tallow from Beef Trimmings
Different ratios of KOH to NaOH can be used to produce bead material of varying physical properties including overall integrity of material ranging from brittle solid (all NaOH) to malleable semi-solid (all KOH). This particular method prepares a fatty material that is malleable enough to apply bead material to wick by hand.
One process for creating a wick for a 2 inch votive is as follows:
Although this technology has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples can perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the disclosed technology and are intended to be covered by the following claims.
