Definitions

  • the embodiments disclosed herein relate generally to candle wicks and methods of making the same. More specifically, the embodiments disclosed herein relate to candle wick assemblies having multiple individual candle wicks that can be associated with a solid candle wax fuel as part of an integral wick system. When lit, the candle wick assemblies allow the multiple candle wicks to separate from one another so as to achieve a broader and shorter flame thereby in turn causing an expanded liquid wax pool to be formed on the surface of the candle.
  • Candles employing a wick have been in existence for many centuries.
  • a typical candle has a single wick, or multitude of wicks, that extends longitudinally through the body of the candle.
  • Single wicks are usually centrally disposed in the candle body.
  • the combustible candle body is typically a thermoplastic blend of petroleum (paraffin) wax, mineral (montan) wax, synthetic wax (polyethylene or Fischer-Tropsch (FT) waxes) or natural waxes (vegetable or animal waxes).
  • Clear candle waxes known as gel candles, have diverse decorating potential. These gel candles are made from mineral oil and special resins. Natural, plant based soybean wax is gaining popularity as a cost competitive, environmental or "green” wax derived from renewable resources.
  • additives used to modify the candle hardness, color, burn rate and aroma are well known in the trade and include, for example, stearic acid, UV inhibitors, polyethylene, scent oils and color pigments.
  • stearic acid Upon lighting a candle wick, the heat melts the wax which then travels up the wick by capillary action and is vaporized.
  • Performance requirements of a wick in a candle include the ability to create and maintain the desired burn rate, the ability to create and maintain the desired wax pool and, if specified or required, the ability to bend or curl to maintain the proper wick height (referred to in the trade as "self-trimming").
  • the finished wick be stable and not subject to size fluctuation when tension is applied to the wick during the candle making or wick pre-waxing process.
  • the ability of the wick to be self-supporting may be preferred, or even required, in certain candle types or candle manufacturing processes, e.g., so-called poured candle constructions where the molten wax fuel is poured into a mold around a pre-positioned and pre-waxed wick and thereafter allowed to solidify.
  • scented candles that may be employed for environmental scent freshening or aroma therapy
  • the size of the liquid pool of wax fuel that forms on the top of the candle is the size of the liquid pool of wax fuel that forms on the top of the candle.
  • manufacturers of scented candles prefer to have a large liquid pool of wax fuel as this increases the scent released into the ambient environment.
  • flame height cannot be too high or the candle flame will then emit undesirable soot that can mar the appearance of the candle and candle holder and nearby surfaces, i.e., by visible smoke being emitted from the candle flame and being deposited as soot on the candle holder and into the environment and/or by the presence of undesirable black carbon droppings that are visible in the liquid wax pool.
  • These carbon deposits can cause secondary ignition, a safety hazard near the end of the candle life.
  • a single conventional wick large enough to produce the necessary heat to form the desired size liquid wax pool often results in an unreasonably high flame, carbon deposits and excess sooting all of which are undesirable and some of which are unsafe.
  • a candle wick could be provided as a single wick assembly having multiple individual wicks that are capable of separating one from another when lit to thereby achieve an increased liquid wax pool size which is of substantially uniform diameter with a single stable and broader flame exhibiting decreased flame height comparable to conventional multiple wick candles, yet can be produced using single wick manufacturing techniques (i.e., since the multiple wicks are separably contained within a single wick assembly). It is towards fulfilling such needs that the embodiments disclosed herein are directed.
  • the embodiments disclosed herein provide multiple candle wicks that may be placed into a candle wax (paraffin) body utilizing conventional single candle wick manufacturing techniques.
  • the multiple candle wicks as described herein will therefore provide for an increased wax pool diameter (thereby increasing the amount of liberated scents from the candle body) with lower flame height (and thereby decreased risk of sooting) at wax burn rates that are comparable to single candle wicks.
  • the multiple candle wicks as disclosed herein will include a wick construction having at least one pair of substantially parallel elongate candle wicks which are laterally separated from one another, and a ladder filament connecting the pair of candle wicks.
  • the ladder filament extends back and forth between the candle wicks (e.g., at substantially 90° relative to the elongate axes of the wicks) so as to establish respective crossing portions that are spaced apart from one another along a lengthwise direction of the construction.
  • the ladder filament is of sufficient flexural stiffness so as to resiliently bias the pair of candle wicks from a compacted position wherein the candle wicks are closely laterally spaced apart relative to one another and into a spread position wherein the candle wicks are further laterally spaced apart relative to one another following release of an applied bending force sufficient to cause the connecting portions to bend about a longitudinal axis of the construction.
  • the ladder filament may be a thermoplastic monofilament, for example a monofilament formed of polyolefin (e.g., polypropylene), nylon, polyester or like thermoplastic materials.
  • the candle wicks may be formed of braided or knitted wick yarns of spun cotton or rayon.
  • the candle wicks may include elongate stiffening elements along the longitudinal extent thereof so as to impart self-supporting characteristics to the candle wicks.
  • a wick assembly is also provided according to the embodiments disclosed herein wherein a wick construction as briefly described above is bent around an exterior circumferential portion of an elongate core element.
  • the crossing portions of the ladder filament may therefore be resiliently bent so that the wick construction assumes a general U-shape around the exterior circumferential portion of the core element to place the candle wicks into the compacted position thereof.
  • An external wax coating may be applied over the core element and the wick construction so as to maintain the candle wicks in the compacted position thereof.
  • the core element may be provided with a core filament and a wax bonding layer on an exterior surface of the core filament.
  • the wick construction may be formed by providing at least one pair of parallel elongate candle wicks which are laterally separated from one another and connecting such candle wicks to one another with the ladder filament so the ladder filament extends back and forth between the candle wicks so as to establish respective crossing portions that are spaced apart from one another along a lengthwise direction of the construction.
  • the wick yarns are knitted into respective candle wicks while simultaneously inserting the ladder filament into the knit structure as a throw yarn back and forth between the knit candle wicks during the knitting process.
  • the wick yarns may be braided to form respective candle wicks, in which case the ladder filament may be stitched to the candle wicks in a back and forth manner.
  • the wick yarns may be woven to form respective candle wicks, in which case the ladder filament may be woven into or stitched to the candle wicks in a back and forth manner.
  • the candle wick construction may be joined with the elongate core element to form the multiple candle wick assembly by bending the crossing portions of the ladder filament about an exterior circumferential portion of the core element so as to place the candle wicks into the compacted position thereof.
  • the candle wicks are maintained in such compacted position by means of a suitable releasable connection with the core element.
  • a suitable releasable connection may be in the form of a thermally releasable wax or thermoplastic adhesive that melts at the ignition temperature of the solid candle wax fuel.
  • a wax or thermoplastic coating may be applied onto such a structure by advancing the core element and the candle wick construction with the crossing portions of the ladder filament bent therearound to an applicator and applying the coating thereto so as to maintain the candle wicks in the compacted position thereof. Allowing the applied coating material to cool and harden therefore maintains the individual wicks in their compacted position with the crossing portions of the ladder filament bent around the circumferential portion of the core element.
  • the candle wick assembly may then be positioned in a body of conventional candle wax (paraffin).
  • one technique involves inserting the wick assembly into a pre-formed hole in a solid wax body.
  • the candle wick assembly may be anchored to the wax body using a conventional metal anchor tab.
  • Another technique that may be practiced includes positioning the wick assembly within a candle mold or container, pouring molten candle wax into the mold or container and allowing the wax to cool to thereby form the wax body and embed the wick assembly therein.
  • FIG. 1 depicts an exemplary burning candle 10 which includes a body 12 formed of a solid, combustible candle wax material provided in a container C formed of any suitable material, e.g., glass, metal, ceramic or the like.
  • the candle wax material forming the body 12 of the candle 10 is provided with dual wicks 14a, 14b in accordance with the present invention.
  • the flame 16 burning at the top end of the candle body 12 creates a generally circularly shaped (as viewed from above) molten wax pool 18 which serves as a reservoir of fuel to be supplied by the wick 14 to allow combustion to continue.
  • each of the wicks 14a, 14b exhibits a wick curl that is opposite to one another. That is, each of the terminal end portions of the wicks 14a, 14b is arced laterally relative to the wick's elongate axis A l so that a portion thereof extends generally at a right angle (e.g., about 90°) relative to the elongate axis A l (see FIG. 2 ). As a result, the terminal ends of the wicks 14a, 14b are generally positioned at the edge of the flame 16 thereby allowing the terminal end portion of the wicks 14a, 14b to themselves to be combusted. As can be appreciated, and as was discussed above, such controlled wick curl and wick combustion allows the wicks 14a, 14b to be self-trimming.
  • the wicks 14a, 14b are provided as part of a self-supporting wick assembly 20 which may be embedded in the wax body 12 of the candle 10.
  • wick assembly 20 containing multiple wicks 14a, 14b is that it may be inserted into a conventional metal anchor tab 22 that is used by numerous manufacturers to anchor a single wick into the wax body of the candle.
  • the wick assembly 20 is generally comprised of a multiple wick construction 30 as shown in FIG. 3 which is maintained in folded state about an elongate core element 40 by wax coating 50.
  • the individual wicks 14a, 14b of the wick construction 30 are cross-connected to one another by a relatively stiff and thereby resilient ladder filament 32.
  • a stiffener filament 24a, 24b may be provided as part of the wick structure.
  • Each of the wicks 14a, 14b may be in the form of conventional braided, knit or woven yarns formed of conventional wick fibers, e.g., cotton, rayon, bamboo, linen, hemp and/or other cellulosic fibers.
  • the wicks 14a, 14b may be knit as described more fully in U.S. Patent No. 6,699,034 .
  • Braided wicks that may be employed in the practice of this invention are also well known in the art as evidenced by U.S. Patent No. 1,496,837 , 1,671,267 , and 5,124,200 .
  • the ladder filament 32 may be stitched to each which 14a, 14b in a zig-zag manner so as to join the wicks 14a, 14b together in a parallel spaced-apart manner with the ladder filament 32 extending therebetween as shown in FIG. 3 .
  • the ladder filament 32 may be laid-in as part of the knitting or weaving process to form the dual wick construction 30 depicted in FIG. 3 .
  • the individual crossing portions 32a will preferably be substantially orthogonal (90° +/-) relative to the longitudinal axes A1, A2 of the wicks 14a, 14b as such an orientation will provide maximum bias resiliency to spread the wicks 14a, 14b apart when the upper end of the wick assembly 20 is lit.
  • the wicks 14a, 14b are formed of a conventional candle wick material, e.g., yarns comprised of cotton, rayon, linen, hemp, bamboo and/or other cellulosic fibers.
  • the stiffener elements 24a, 24b may be a filament or yarn formed of any suitable synthetic or natural fibrous material provided it imparts the requisite stiffening properties to the wicks 14a, 14b.
  • stiffener elements 24a, 25b having a flexural stiffness (Young's modulus) of between about 0.5 to about 10 MPa can satisfactorily be employed in the practice of the embodiments of this invention.
  • stiffener elements 24a, 24b include thermoplastics, e.g., polyolefins such as polypropylene or polyethylene, nylons, polyesters and the like.
  • the stiffener elements 24a, 24b are monofilaments of polypropylene as such a material provides the desired stiffness in order to promote self-supporting capabilities to the wicks 14a, 14b so as to be capable of extending upright along the axes A1, A2, respectively, without the aid of external support.
  • the monofilaments forming the stiffener elements 24a, 24b will exhibit a required melting temperature of greater than the melt temperature of the wax body 12, e.g., greater than about 220°F (105°C).
  • wick stiffener elements 24a, 24b can therefore be polypropylene monofilaments having a diameter from about 0.01 inch to about 0.05 inch.
  • the stiffener elements 24a, 24b may also be formed of a multifilamentary yarn of spun natural fibers, such as cotton or rayon, provided with a coating material to impart stiffness to the yarn.
  • Suitable thermoplastic coating materials such as polyolefins, nylons, polyesters, polyurethanes and the like may be employed for the purpose of imparting stiffness to the natural fibers of the multifilamentary yarn so that the elements 24a, 24b will exhibit the desired flexural stiffness as discussed previously.
  • a finished multifilamentary yarn of spun natural fibers coated with a suitable thermoplastic coating material can be between about 1400 to about 3600 denier.
  • stiffener elements 24a, 24b may be laid-in when forming the wicks 14a, 14b or stitched between the wicks 14a, 14b so as to be part of the wick structure.
  • the wick construction 30 will be folded about the core element 40 so that the crossing portions 32a of ladder filament 32 are positioned about a circumferential portion of the exterior surface of the core element 40. As shown in FIG. 4 , the wick construction 30 will thus assume a generally U-shaped configuration when part of the wick assembly 20. When in such U-shaped configuration, the wicks 24a, 24b of the construction 30 will therefore be in a more compact arrangement relatively to one another since the separation distance thereby will be relatively closer (e.g., a separation distance therebetween which is not more than the diameter of the core element 40) as compared to the spread condition as shown in FIG. 2 .
  • the ladder filament 32 must therefore possess sufficient flexural stiffness in order to achieve the required resiliency and exert spring bias force to spread the wicks 14a, 14b when folded about the core element 40.
  • the ladder filament 32 may thus be similar to the stiffener elements 24a, 24b and thus may be formed of a thermoplastic polymer, e.g., polyolefins, such as polypropylene, nylons, polyesters and the like or thermoplastic coated multifilamentary yarns of spun natural fibers.
  • the ladder filament is a polypropylene monofilament having a diameter of between about 0.1 mm (0.004 inch) to about 0.38 mm (0.015 inch), e.g., about 0.2 mm (.008 inch).
  • the core element 40 can be virtually any elongated filamentary element having sufficient structural integrity to allow the ladder filament 32 to be folded therearound.
  • the core element 40 may therefore be virtually any filamentary or multi-fibrous element which includes spun yarns of staple fibers, multifilament bonded yarns or monofilaments made of thermoplastic materials.
  • One such filament that may satisfactorily be employed in the embodiments disclosed herein as the core element 40 is a polypropylene monofilament having a diameter of between about 0.1 mm (.004 inch) to about 0.4 mm (.016 inch), e.g., about 0.15 mm (.006 inch).
  • the core element 40 may optionally include a core filament 42 which is surrounded by a wax bonding layer 44.
  • the wax bonding layer 44 serves to releasably bond the wicks 14a, 14b to the core element 40 and thereby maintain the wick construction 30 folded in a U-shaped configuration therearound until the final wax coating 50 can be applied.
  • the wax bonding layer 42 preferably has a melt temperature that is the same or less than temperature of the liquid wax pool 18, e.g., a melt temperature which is typically 220°F (105°C) or less.
  • the core element 40 may be formed entirely of a wax material, i.e., the core filament 42 may then be omitted. If made entirely of a wax material, the core element 40 may then serve the function of bonding the wicks 14a, 14b together in a compacted position (in which case the wax coating 50 may not necessarily be required for such purpose) while at the same time keeping the wicks 14a, 14b physically separated by virtue of the core element's diameter.
  • thermoplastic components of the wick construction 30, e.g., the stiffener elements 24a, 24b, the ladder filament 32 and the core element 40 will be consumed by the flame 16 thereby allowing the wicks 14a, 14b to curl outwardly as described above.
  • all thermoplastic elements near the flame 16 will be consumed to thereby leave only the wicks 14a, 14b in contact with the liquid wax pool 18.
  • FIG. 5 A schematic diagram of a continuous manufacturing process to form the multiple wick construction 30 and the wick assembly 20 is depicted in accompanying FIG. 5 .
  • the process initially involves supplying wick yarns WY1 and WY2 from supply spools 60, 62, respectively, concurrently with a ladder filament 32 from a supply spool 64 thereof to a knitting machine 76.
  • the stiffener filaments 24a, 24b are concurrently supplied to the knitting machine 76 from respective spools 68, 70, thereof.
  • the wick yarns WY1 and WY2 may be spun yarns of cotton, rayon or other cellulosic fibers.
  • Cotton yarns are preferred and will have a size that is dependent upon the size and/or style of the finished wick intended for a particular size and/or style of candle in which the wick is used. Cotton yarns may therefore vary greatly between, e.g., 60/1 to 8/2 ring spun or open spun cotton yarns.
  • the knitting machine 76 thus forms a knitted construction to provide the wicks 14a, 14b in which the stiffener filaments 24a, 24b are laid-in.
  • the knitting machine 76 knits the ladder filament 32 as a throw yarn back and forth between the wicks 14a, 14b to thereby form the wick construction 30.
  • the wick construction 30 may then be continuously passed on to the wax coater 72 simultaneously with the core element 40 being supplied to the coater 72 from a spool 74 thereof.
  • the core element 40 is joined with the wick construction 30 at junction rollers 78 which are configured so as to fold the latter around the former before proceeding on to the wax coater 72.
  • the core element 40 may optionally be passed through a core element coater 78 before being joined to the wick construction 30 so as to provide the core element 40 with the wax coating 44 as described previously.
  • the wick assembly 20 thereby exits the coater 72 and is cooled to allow the exterior wax coating 50 to solidify (e.g., by either ambient air or by being passed through a cooling chamber) before being taken upon on a spool 80.
  • the process shown in FIG. 5 may be modified in various ways.
  • the process may be discontinuous such that the wick construction 30 is taken upon on an intermediate spool.
  • the wick construction on such a take-up spool may then be transported to a final assembly location whereby the wick construction 30 is joined with the core element 40 and coated with the wax coating 50 to form the wick assembly 20.
  • the core element 40 may be pre-waxed when taken off its supply spool 74 and joined with the wick construction 30 at the roller junction 76, in which case the core element coater 78 is not necessarily required.
  • the core element 40 may be formed entirely of a wax material
  • the core element 40 may be extruded in the form of a wax filament which is placed between the wick assembly 30 as it is folded by the rollers 78 prior to entering the final wax coater 72.
