Multiple candle wick assemblies and methods and apparatus for making the same
A multiple candle wick products are disclosed which include at least one pair of candle wicks each having a knit construction and defining a terminal end which is adapted to being burned in use and a ladder filament connecting the pair of candle wicks. The knit construction of the candle wicks is such that during burning each respective terminal end of the candle wicks curls outwardly opposite to one another relative to an elongate axis thereof.
1 . A multiple candle wick product comprising a wick assembly which comprises:
(i) at least one pair of candle wicks each having a knit construction and defining a terminal end thereof adapted to being burned in use; and
(ii) a ladder filament connecting the pair of candle wicks, wherein
the wick assembly is folded into a U-shaped configuration such that the at least one pair of candle wicks are in a spaced-apart parallel compacted condition relative to one another, and wherein
during burning the at least one pair of candle wicks spread apart to assume a spread condition where the at least one pair of candle wicks are spaced-apart by a distance greater than the compacted condition thereof, and wherein
the knit construction of the candle wicks is such that during burning each respective terminal end of the candle wicks curls outwardly opposite to one another relative to an elongate axis thereof.
2 . The multiple candle wick product according to claim 1 , wherein 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.
3 . The multiple candle wick product according to claim 2 , wherein the ladder filament is of sufficient flexural stiffness so as to resiliently bias the pair of candle wicks from the compacted condition and into the spread condition thereof.
4 . The multiple candle wick product according to claim 1 , wherein the crossing portions are substantially orthogonal to respective elongate axes of the candle wicks.
5 . The multiple candle wick product according to claim 1 , wherein the candle wicks include elongate stiffening elements to impart self-supporting characteristics to the candle wicks.
6 . The multiple candle wick product according to claim 1 , wherein the ladder filament is a thermoplastic monofilament.
7 . The multiple candle wick product according to claim 5 , wherein the stiffening elements are selected from the group consisting of thermoplastic monofilaments and spun yarns of natural fibers coated with a thermoplastic material.
8 . The multiple candle wick product according to claim 6 , wherein the wick yarns comprise fibers selected from the group consisting of spun cotton fibers, rayon fibers, hemp fibers, linen fibers, bamboo fibers and cellulosic fibers.
9 . A candle which comprises a wax body and the multiple candle wick product according to claim 1 positioned in the wax body.
10 . A method of making the multiple candle wick product according to claim 1 , wherein the method comprises:
(a) providing the at least one pair of parallel elongate candle wicks having a knit construction which are laterally separated from one another; and
(b) connecting the candle wicks to one another with the ladder filament by joining the ladder filament to the candle wicks in a 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 multiple candle wick product.
11 . The method according to claim 10 , which comprises joining the ladder filament to the candle wicks so the crossing portions thereof are substantially orthogonal to respective elongate axes of the candle wicks.
12 . The method according to claim 10 , which further comprises inserting an elongate stiffening element into the candle wicks to impart self-supporting characteristics thereto.
13 . The method according to claim 12 , wherein the stiffening element is selected from the group consisting of thermoplastic monofilaments and spun yarns of natural fibers coated with a thermoplastic material.
14 . The method according to claim 10 , wherein the ladder filament is a thermoplastic monofilament.
15 . The method according to claim 10 , wherein the candle wicks are formed of wick yarns selected from the group consisting of spun cotton yarns, rayon yarns and cellulosic fiber yarns.
