Wick has been used for centuries to provide a dependable flame. Commonly made out of cotton or hemp, wick can be found in candles, lanterns, heaters, and many such devices which require a source of flame. While modern lighters and matches have mostly replaced the wick in everyday life, using pre-waxed wick is experiencing a resurgence in popularity for reasons related to health, environmental, cost and lifestyle benefits, such as pre-waxed wick's attractiveness for outdoor use.
Using pre-waxed wick, often made with natural hemp cord and bees-wax, is a natural alternative to butane lighters and matches. It preserves the flavor of fine tobacco and reduces harmful exposure to butane. Pre-waxed wick is waterproof and allows for an extended reach when lighting grills, pilot lights, stoves and campfires, among other uses. The lighted wick continues to burn, more quickly than a candle, until extinguished by snuffing or blowing.
One currently common method for storing and transporting pre-waxed wick is to wrap it around a device of convenience and extend one end to be lighted. One such popular device is a butane lighter. While this method offers some convenience, wrapping a tank of flammable liquid with a product designed to easily ignite and remain burning, such as pre-waxed wick, can result in a hazardous fire. Another popular device around which wick can be wrapped is a smoking pipe, commonly made of wood or glass. While these devices have some inherent flame-retardant qualities, they do not address the lack of a flame barrier between the lighted wick and the stored wick. Simple distraction can lead to wasting wick or causing a potentially hazardous fire.
Another safety issue with storing and transporting pre-waxed wick wrapped around a device of convenience, such as a lighter or smoking pipe, is that a length of wick is often stored in the same area designated to be grasped by the user's hand. The hazard in this method is that the wax embedded into and coating the pre-waxed wick allows the lighted wick to continue to burn, possibly into the user's hand, and the embers of a just-extinguished wick-end can continue to glow hot while still exposed to the air. Also, pre-waxed wick is rough and sticky, making it somewhat uncomfortable to the touch.
Many people, such as those with sensitivities to smoke, find it preferable to snuff out a flame rather than blow it out, as snuffing results in less smoke being released into the air. Others may prefer snuffing due to difficulties with focused blowing caused by impairments to the lungs or muscles surrounding the lips and mouth. Manually snuffing out a flame can be an awkward and dangerous maneuver: using water requires a water source to be located nearby; using one's fingers can possibly cause a burn; using one of the many devices available for snuffing out a candle decreases the convenience of burning hemp wick by requiring the use of a secondary tool not included with the dispensing device.
Further issues arise for those persons who have been hampered with physical impairments, such as impaired manual grip-strength and dexterity. Some may find it difficult to securely hold the thin strand of lighted wick without a dispensing device which can be held securely in the hand. Some may also find it difficult to bring their fingers precisely together in order to snuff the lighted wick.
Since the invention of the candle, one of the most ancient methods for burning wick, wick extinguishing devices have been introduced and modified upon. These devices have included: dome shaped snuffers; movable tubes, tongs, arms and cap snuffers; air powered extinguishers; removing the fuel source, such as wax, oil or butane, from the wick by inserting a barrier; or other means. However, those devices which extinguish a lighted wick by removing air from the combustion process either rely on moving parts, require some level of mechanical or human interaction after the wick has been lighted, or do not address the need for a user to easily and exactly select the length of wick to be burned and then automatically extinguished.
For example, Millar, U.S. Pat. No. 4,497,374, describes a candle snuffer with parallel elongated tines and a handle, looking like a two-pronged fork, in which the space between the tines is slightly larger than the thickness of a normal candle wick. The snuffer is used by positioning the base of the lighted wick between the tines and lifting the device up and over the flame, immediately extinguishing the flame. Millar provides an adequate means of safely extinguishing a burning wick. But, the manner of extinguishing does not occur automatically and requires a certain level of manual dexterity to properly position the snuffer around the burning wick.
In comparison, Viggiani, U.S. Pat. No. 7,841,857 B2 provides a means of automatically extinguishing a burning candle by means of a scissor-like apparatus which snuffs the burning wick when it has burned down into the apparatus enclosure. Viggiani allows for a user to select the length of candle to be burned before lighting the wick, and no further human intervention is required to snuff the burning candle. However, this device relies on moving parts to secure the section of candle into the apparatus. Moving parts can break or wear down with use, reducing the device's ability to securely hold and extinguish the burning candle.
Finally, Keiffer et al., U.S. Pat. No. 7,578,670 B2, teaches of a self-extinguishing candle comprising of a series of appliances, each enclosing a portion of wick intended to be burned. When the candle burns down to where the wick has reached the top the first wick appliance, the impenetrability of the wick appliance will smother the flame, along with any molten wax that may flow into the hollow channel within the appliance containing the next portion of wick to be burned. However, the length of the appliance is predetermined and the user cannot exactly select the length of wick to be burned before lighting the candle.
In response to the growing popularity in using pre-waxed wick, devices can now be purchased which are intended for that use. Each of these devices allow for the storage and dispensation of wick. However, improvements can be made towards their ease of use, especially for those persons with impairments to the use of their hands who may find it difficult to use any one of these devices.
Quikwicks “Wooden Hemp Wick Dispenser” [quikwicks.com AND indiegogo.com/Quik-Wick] stores a length of hemp wick and a small butane lighter within the main body of the device, which is not much bigger than a standard disposable butane lighter. The user dispenses the portion of wick intended to be burned, and lights the end of the wick with the small butane lighter contained within the device. Wick dispensation is achieved by turning a small wheel partially exposed on a narrow edge of the device. While the description of this product on the Quikwicks website is not clear on the method of extinguishing the burning wick, two methods can be inferred. One method would be to extinguish the flame by blowing. A second method would allow the wick to burn down to the small metal tube from which the wick is dispensed, hidden with the device, where the flame would be snuffed. While this device is a successful wick storing, dispensing and lighting device, those people hampered with impairments to the use of their hands may find it difficult to turn the small wheel in order to dispense the next portion of wick intended to be burned, and refill the small chamber within the device with wick.
The remainder of the wick holders available at the Quikwicks Smoke Shop online store [http://shop.quikwicks.com/collections/gong] require an average or better level of manual dexterity to dispense the wick. A length of hemp wick is stored in a jar. The top of the jar is made of glass or cork which pulls out of the main body, or a metal screw-top, each top containing a hole slightly larger than the thickness of the wick through which the wick is fed. A portion of wick intended to be burned is pulled out of the jar through the hole. The burning wick is extinguished either by blowing, or by allowing the wick to burn down to the hole in the top, thus extinguishing the flame by snuffing.
While this device is a successful wick storing device, allowing the burning wick to snuff out in the top leaves only the smallest stub of charred wick-end exposed. Even those with average manual dexterity may find it difficult to grasp the charred wick-end securely enough to pull out the next portion of wick. Also, touching the charred wick-end leaves black soot on the fingers. Another device, such as tweezers, could be used to rectify these problems. However, this decreases the level of convenience of the dispensing device, necessitating the use of a secondary tool not included with the dispensing device.
The Humboldt Traders online store seems to bear some relation to Quikwicks and sells hemp wick dispensers similar to Quickwicks but made entirely of glass. [humboldt-traders.com/hempwickdispenser/] The description on their website is limited and it is unclear whether the hole in the top extinguishes the burning wick. However, the same problems arise as with the aforementioned Quickwicks holder, in that one method of retrieving the next portion of wick intended to be burned necessitates pulling up the charred wick-end from the top. While the glass top may allow for pushing up more wick from the bottom of the hole, this method requires repeated re-threading of the wick into the hole in the top which may be difficult for those with impairments to the use of their hands.
Beeline's online store sells the “Wickit Wand” [http://www.thebeelinestore.com/wickitwand.html]. This device is made of metal and comprised of a wick storage area, two outer arms held apart by tension, and a tip which uses the tension of the outer arms to securely hold the wick between two faces. This device allows the user to select the length of wick to be burned and automatically extinguishes lighted wick at the tip by snuffing. However, the tension in the outer arms can diminish with repeated use, decreasing the effectiveness of the tip's ability to securely hold and extinguish the lighted wick. Also, threading the wick into the tip of the device may be difficult for those with impairments to the use of their hands.
The present invention is large enough to be held securely in the hand and/or stand on its own, such as on a table. It allows the user to select the length of wick to be burned by removing a desired portion from the wick storage area and securing that portion of wick into the extinguishing notch, made from a flame-retardant and durable material such as metal. When the flame has burned through the desired portion of wick and reaches the extinguishing notch, air is removed from the combustion process and the lighted wick is automatically snuffed. The extinguished wick-end remains lodged in the extinguishing notch, and a recess located directly under the extinguishing notch allows for easy retrieval of the wick for the next use. The device's ability to safely and automatically extinguish a flame does not diminish with repeated use as no moving parts are involved in the dispensing and extinguishing processes.
Accordingly, it is a principal object of the invention to provide a lighted wick extinguisher.
It is another object of the invention to provide a lighted wick extinguisher that accomplishes this passively, without mechanical or human interaction.
It is a further object of the invention to provide a lighted wick extinguisher that uses the notch to remove air from the combustion process in order to extinguish the lighted wick.
Still another object of the invention is to provide a lighted wick holder which can be comfortably and securely held in the hand, or stand on its own.
It is yet another object of the invention to provide a designated area incorporated into the device to store a length of wick.
It is yet a further object of the invention to provide an easy method of dispensation of a desired portion of wick.
It is a further object of the invention to provide a lighted wick extinguisher that is unique and aesthetically pleasing.
