This invention relates to the field of candle and wick designs and their manufacture.
The consumer candle market has increased dramatically with time. Two problems that have persisted in the candle market despite developments in the candle making art are 1) the ability to make candles safer and prevent causing fires and 2) prevent forgetting a candle is lit and wasting the candles wax fuel. While there are some products on the market that help to accomplish these goals and they have some degree of commercial success, they are cumbersome and depart significantly from the traditional and classic look of a cylindrical open top candle and detract from the candles overall attractiveness.
This invention is designed to address 2 problems related to the burning of candles by consumers. The first is a desire by the consumer to protect their home or building from fire caused by the burning of a candle. The second is the desire by the consumer to be able to better manage the burning of their candle so as not to waste the candle by forgetting the candle is lit for an extended period of time. This invention is a wick system which allows the user to light the candle in the same manner as a traditional candle and after a predetermined period of time have the flame extinguish automatically. After the flame extinguishes, due to the configuration of several parallel wicks in the wick system, a new wick will have been exposed by the reduced wax level. This pattern will continue so that each wick burns for the predetermined period of time. The self extinguishing property of the candle wick system gives consumers peace of mind that if the candle is mistakenly left unattended, the chance of fire has been dramatically reduced by the significant reduction in time that the candle can burn unattended. Additionally, a consumer has the peace of mind that if the candle is mistakenly left unattended, it will not waste a significant portion of the candle. No unusual tasks or manual processes are required beyond the typical lighting of a candle that consumers are familiar with. In addition, the manufacture process is extremely simple and can be applied after a candle or wick is already manufactured.
The system consists of 2, 3, 4 or more parallel wicks which have been severed into segments. The segments are generally even but do not always need to be. The length of the segments is determined based on the desired incremental burn time of the candle. The wicks are offset from each other within the candle such that as a wick segment burns, it reveals the next wick segment to be lit by the time the previous wick self-extinguishes. This process continues until the wax system reaches the bottom of the candle and the wax fuel is used up.
The detailed description of some of the embodiments of the invention is made below with reference to the accompanying figures, wherein like numerals represent corresponding parts of the figures.
In the following detailed description of the invention, numerous details, and examples of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.
The device and wick system of the present disclosure may be used to create a self extinguishing candle in addition to automatically generating a new wick that may be relit without any additional steps for the user to follow than may apply to a traditional candle and wick. The wick system itself may be used in an abundance of applications and is not limited to this application. The wick system is intended to develop a method in which a wick, however it may be extinguished, may automatically generate a new wick to be lit by the user. In addition, this invention incorporates a method of extinguishing the flame that involves causing the wick to tumble into the molten wax pool and extinguish by removing oxygen from the flame.
The embodiment shown in this example of the invention includes the following elements:
The above elements are listed not to limit the elements that may be incorporated into the invention and wick system, but rather to better describe this most basic version of the invention.
By way of example, referring to
Referring to
The wax matrix may be of any manufacture and the wick may be of any manufacture. Modest testing may be done between any new wax and wick pair in order to determine the desired length needed for each wick segment in order to achieve the desired amount of burn time for each segment.
A significant improvement of this invention is the simple manufacture process for implanting the Timed Candle Wick System into an existing unwicked wax matrix by drilling or otherwise forming a bore into a solid wax matrix to specified depths and then inserting the wick segments back to back until the bore is full and the bottom wick segment touches the bottom depth of the respective bore.
Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of both the toppling method of extinguishment as well as the offsetting wick system which regenerates a fresh wick for lighting in this invention. Thus, given the wide variety of the configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
There have been many attempts at manipulating the burning of a candle or candle wick in a manner that self extinguishes the flame or otherwise makes the candle safer. However, no prior art utilizes the same methods and designs present in the current invention. Further as a benefit of these design differences, no prior art achieves the functionality and ease of manufacture benefits that the current invention makes allowable. Below is a brief overview of relevant prior arts and notable critical differences between them and the current invention. US20090233249A1—Self Extinguishing Candle. Operates by surrounding wick with fire suppressant layer intermittently between wax fuel layers. Fire suppressant layer denies access to wax fuel once flame reaches suppressant layer, causing flame to extinguish. Suppressant layer may be removed in order to allow access to new wax fuel layer. Method of Extinguishment: Denying wick access to wax fuel. Method of Relighting Candle: Manually remove suppressant layer to expose fresh wax fuel. US20060292508A1—Self Extinguishing Candle. Operates by interrupting the wick's access to the wax fuel by inserting impermeable layers intermittently into wick itself, thereby preventing wick from being able to use capillary forces to draw up melted wax fuel. In this prior art, an impermeable layer may also include a gap in which the wicks are connected by a small fiber in order to maintain the structural integrity of the wick as the flame melts the wax towards the gap in each wick section (FIG. 4 in Prior Art). This is one of several critical distinctions between this prior art and the current invention. Namely, the current invention intentionally removes any structural support at the base of each wick section, ensuring wick segments are completely severed in order to allow the wick to tumble mechanically as the wax liquifies beneath the severed wick, which is critical to the functionality and ease of manufacture of the current invention. Another form of this prior art has two parallel rows of wicks separated intermittently by gaps in the wicks (FIG. 7 in Prior Art). There are 4 critical distinctions between this form of the prior art and the current invention that critically impact functionality and ease of manufacture. The first is that in this prior art a significant gap is placed between the various severed segments of each column or series of wicks; whereas, although the current invention relies on severed wicks, it intentionally places no gap between those severed wicks as a critical component of the functionality of the invention. A gap would cause the current invention to fail to be relightable by pushing the wick segment beneath the gap beyond the zone in which the wax level drops during the burning of the preceding wick segment and cause the remaining wick segments to be out of sync in the same manner. Secondly, the Prior Art requires prefabricating special wicks encased in wax in order to place strategically within a candle container prior to wax being poured into the candle container. The Prior Art contemplates inserts separate wax encased wicks in a left right stair step pattern. The current invention has one continuous column of severed wicks that are stacked directly on top of each other to give the effect of a continuous wick with severed locations periodically. The current invention allows for regular wax wicks to be modified by severing them at specified lengths and then inserting them without further modification into pre-poured wax candles. This allows for any wick manufacturers wick to be used and placed into any candle manufacturers candle after the normal manufacture process is complete for both wick and candle. Additionally, intentionally not placing a gap between the severed wick segments allows for easier and less costly implantation of the wick, requiring merely drilling or otherwise boring into the solid wax and inserting the various wick segments back to back into the candle. The third critical distinction is that all forms of this Prior Art rely on the wick burning to completeness in order to properly function and expose the subsequent wick section. The current invention specifically relies on the wick not burning to completeness and instead relies on the wick tumbling due to mechanical instability once the melted wax reaches the base of the severed portion of each wick section. The fourth and final critical distinction is that all forms of this Prior Art rely on removing the fuel source from the flame by disrupting the capillary action in the wick by way of an impermeable section in the wick. In some forms the impermeable section of the wick is the solid wax fuel itself, which is impermeable to liquefied wax. This is a critical difference compared to the current invention which at no time interrupts the capillary action of the wick or denies the wick access to liquified fuel. Instead, the current invention extinguishes the flame by denying oxygen to the flame at certain predetermined points in time during the burning process. U.S. Pat. No. 7,578,670B2—Self Extinguishing Candle. Involves single continuous wick with portions of the wick covered by a “wick appliance” that has the effect of making the wick impermeable at the location of the appliance. The flame is snuffed out by the impermeability of the wick appliance denying wax fuel to the wick. The appliance is removed manually after the wick burns out, which reveals a fresh portion of the same continuous wick and allows for renewed permeable contact between the wax fuel and the wick. Method of Extinguishment: Denying wick access to wax fuel. Method of Relighting Candle: Manually remove suppressant tool to expose fresh wax fuel. US20030124474A1—Self Extinguishing Candle. Incorporates flame retardant elements into wick. Method of Extinguishment: Denying wick access to wax fuel. Method of Relighting Candle: Unknown. US20110076631A1—Self Extinguishing Candlewick. Continuous wick surrounded by non-flammable sleeves which snuff out the flame. Method of Extinguishment: Denying wick access to wax fuel. Method of Relighting Candle: Manually remove suppressant sleeves to expose fresh wax fuel. US20040091829A1—Self Extinguishing Wick and Method of Producing the Same. Method of Extinguishment: Denying wick access to wax fuel via a combustion barrier. Method of Relighting Candle: Manually remove suppressant barrier and manually extract wick, or may not be possible to extract wick. In an alternate form of this prior art a wick directly beneath and in the longitudinal path of the previously burned wick is exposed at an angle in order to be subsequently lit. Beyond the obvious differences in this prior arts functionality and method of extinguishment compared to the current invention, it should be noted that an additional critical difference is that this prior art uses only one series of wicks in the longitudinal direction and requires each subsequent wick to be longer than the longitudinal path in which the wicks lie, requiring special manufacturing processes to incorporate the wick before the wax is poured into the candle holder. This is a disadvantage from the current invention, which may be incorporated after a candle is manufactured and in a separate facility if desired. Making retooling at the original manufactures facility unnecessary. Various other prior arts exist that rely on some combination of 1) denying wick access to melted wax fuel, 2) using an accelerant or some other chemical to snuff out the candle flame, 3) using a mechanical device to reveal a new wick capable of being lit after the initial wick extinguishes, 4) require special manufacturing procedures during or before the candle or wick material is manufactured, and 5) use a mechanical device to deny the flame oxygen. AU of the above methods differ critically from the current invention in function and effect. Importantly many of the characteristics incorporated in the above prior arts would in fact cause this invention to fail if they were used in this invention. Further, the design of this invention improves upon any of the prior arts existing by improving the reliability and functionality of the final timed candle wick system in addition to vastly simplifying the manufacture process and making the wick system easily applicable to all wick and candle manufacture types.
