  • the present invention also encompasses articles of commerce comprising 1) the candle of the present invention, and 2) a set of instructions directing the user how to utilize the candle.
  • the article of commerce comprises a candle wherein the candle is within a container in association with a set of instructions, wherein the instructions direct the user to follow the method of utilizing the candle.
  • the instructions may be in the form of written words, pictorials, symbols/icons, and the like, as well as combinations thereof. In one embodiment, such instructions would direct the user to 1) carefully remove any outer packaging from the container candle, 2) place the container candle on a flat heat resistant surface away from flammables; and 3) carefully light the candle wick.
  • "in association with”, when referring to such instructions, means the instructions are either directly printed on the candle and/or the container; directly printed on the packaging for the container candle; printed on a label attached to the candle and/or the container; printed on a label attached to the packaging for the container candle; or presented in a different manner including, but not limited to, a brochure, print advertisement, electronic advertisement, broadcast or internet advertisements, and/or other media, so as to communicate the set of instructions to a user of the candle.
  • a candle comprised of more than one region and/or more than one phase can be made by providing an inner portion/core region that extends vertically above the fill level of the molten fuel of the outer portion/bulk phase, allowing the bulk phase molten fuel to at least partially solidify, and then optionally partially re-melting the surface of the candle. A phase is considered partially melted if at least some liquefied fuel is present.
  • One non-limiting method of making a candle having more than one phase in accordance with the present invention includes the first step of creating a solid inner portion or core containing a candle wick. Molten fuel that will form the outer portion/bulk phase is then poured into a container of a suitable size. The solid core containing the wick is then inserted into the container containing the molten bulk phase. In one non- limiting embodiment it is preferred that the density of the solid core be equal to or greater than the density of the molten bulk phase at the time the phases are combined so that the solid core does not float in the molten phase.
  • the molten bulk phase is comprised of a paraffin wax at a temperature of about 80 0 C with a density at that temperature of between about 0.70 grams/cm 3 and about 0.95 grams/cm 3 or between about 0.75 grams/cm 3 and about 0.90 grams/cm 3 .
  • the density of the molten liquid wax at a given temperature is determined by use of a hydrometer as described in ASTM Method D 1298- 99 (available from ASTM International of West Conshohocken, Pennsylvania).
  • the solid fuel core is paraffin wax at a temperature of about 23 0 C with a density at that temperature of between about 0.8 grams/cm 3 to about 1 grams/cm 3 or from about 0.85 grams/cm 3 to about 0.95 grams/cm 3 at the time of insertion into the molten bulk phase.
  • the density of the solid fuel core is determined according to the method described in ASTM Method D 792-00.
  • the amount of molten wax is chosen so that when the solid core and molten bulk phase are combined, the bulk phase rises to within about 7 mm or less of the top of the solid core or to within about 13 mm or less of the top of the solid core wherein the differential between the height of the bulk phase and the top of the solid core is measured from the highest point of the bulk phase.
  • the candle is then allowed to cool until the molten bulk phase has at least partially solidified.
  • the top of the candle is then subjected to enough heat sufficient to partially melt both the core and the bulk phases.
  • at least about 20 mm in depth from the top surface of the bulk phase is preferably solidified and more preferably the entire bulk phase is solidified prior to heating.
  • the amount of melting is controlled so that molten fuel does not completely cover the top of the core region.
  • from about 1 mm to about 20 mm in depth of the top surfaces of the core and/or the bulk phase may be liquefied. This step helps smooth imperfections in the candle surface such as defects on the top surface of the core phase, sharp edges between the core phase and the bulk phase, and deformations due to wax shrinkage during cooling.
  • the solid core can be inserted into the container prior to pouring the molten bulk phase into the container.
  • the solid core can be made by any known process, such as cold-pressing, extruding, or preferably by pouring molten wax into suitable molds.
  • the solid core may be of any cross sectional shape including but not limited to round, oval, triangular, star shaped, floral pattern, etc. It may also have a varying cross sectional shape so that different shapes appear as the candle is burned.
  • the solid core is made by melting a mixture of 93% by weight of PARAFFLEX 4635 A and 2% by weight of ASTORLITE C by heating the mixture to about 75°C, then adding about 5% by weight of fragrance. About 57g of the molten mixture is then placed into a cylindrical mold having a diameter of about 37mm, and a depth of about 76mm.
  • the mold if desired may optionally comprise a small taper.
  • One non-limiting way of achieving this is by having a 2mm decrease in diameter from the top to the bottom of the mold.
  • any known mold release can be utilized to aid in removal of the core from the mold. After the fuel cools sufficiently to solidify it is removed from the mold.
  • a hole of approximately 0.125 inch (3.175 mm) diameter is then bored in the center of the core.
  • a wick is inserted through the bore.
  • One suitable wick for this purpose is available as SUPERIOR 600 from Wick n'Clip Incorporated of Woodridge, New Jersey.
  • the wick may optionally include a wick sustainer which would be crimped to one end of the wick.
  • a suitable wick sustainer is available as Part No. TPB-20-Long from Wick-n'-Clip Incorporated.
  • the container which will hold the candle is preheated prior to the addition of the solid core or the molten wax.
  • the container may be heated by convective or radiant heat to a temperature of from about 100 0 F (38°C) to about 160 0 F (71°C) prior to insertion of the solid core.
  • This range has been found to be beneficial in helping prevent surface irregularities in the candle such as air bubbles, pits, and/or swirls.
  • the wick contained in the solid core phase can then be glued to the container using any suitable glue.
  • One suitable glue for this purpose is HM2164L available from Adhesives Specialists of Allentown, Pennsylvania. Gluing of the wick and wick clip to the container has the advantage of preventing wick movement during burning of the candle.
  • additional heating of the container may occur after insertion of the solid core into the container, but prior to pouring the molten bulk phase.
  • the final surface temperature of the container may be from about 100 0 F (38°C) to about 160 0 F (71°C).
  • This two- stage heating method has the advantage of achieving the desired final container temperature with reduced melting of the solid core before pouring of the molten bulk phase.
  • the container may be preheated only after insertion of the solid fuel core.
  • the solid core is added to the container before the molten bulk phase, when pouring the molten bulk phase, it is poured so as to avoid pouring the molten wax directly on top of the solid core phase.
  • the molten bulk phase may be poured so that the surface of the molten phase after pouring is from about 13 mm or less, or about 7 mm or less from the top of the solid core phase.
  • the resulting candle comprised of more than one phase/region is allowed to cool for about one hour.
  • the top of the candle then may optionally if desired, be submitted to radiant heat sufficient to partially melt both the core and bulk phase. It is generally desirable to control the amount of melting so that molten fuel from the bulk phase does not completely cover the top of the solid core phase.
  • the resulting candle contains visually distinct regions non-limiting examples of which are shown in FIGS. 1 and 4.
  • Non-limiting examples relating to the instant invention are disclosed below.
