DETAILED DESCRIPTION OF THE INVENTION

(8) FIG. 1 illustrates a candle 11 that provides scent or aroma to the surrounding atmosphere during burning of the candle. The candle 11 has a body 12 made of a flammable or combustible material, such as wax or fat, that can provide a solid body 12 at room temperature, approximately 70 F. The candle 11 includes a wick 15 embedded in the body 12 and extending from an upper end 17 of the body 12, providing an exposed portion 19 for lighting and burning. The candle 11 also has a lower end 18 usable to support the candle during use. Typically, a wick 15 extends generally longitudinally of the body 12 and is generally centrally located within the body 12. Such a wick 15 can be made of a braided fibrous material, such as cotton, as is known in the art. As described above in the Background, an ignition source, such as a match, is held close to the wick 15 until a flame 21 is created. The flame 21 melts or liquefies the flammable material of the body 12, then volatilizes the melted material, which then ignites and perpetuates the flame 21 by providing a combustible gas or liquid to the flame 21. The functioning of candles is well known in the art. The body 12 can be any suitable shape, such as generally cylindrical, tapered, carved on the exterior, or any other suitable shape. The body 12 can also be of any suitable size and color, or colors.

(9) The body 12 can be made of any suitable combustible or flammable material, such as wax or fat, so long as it can form a structure that is solid at room temperature. Paraffin wax can be used, as well as animal fats and/or natural waxes, such as beeswax. It is to be understood that while a candle is a solid structure at room temperature, this does not preclude the material forming the body 12 from having liquids therein. Such combustible materials are generally a mixture of various molecular weight components. This is particularly true for animal fats.

(10) The candle 11 is provided with one or more scent elements 31, as best seen in FIGS. 1-3. As shown, the body 12 has one or more bores 33 extending generally longitudinally of the body 12 and can be generally parallel to the wick 15 and open on the upper end adjacent the wick 15, while closed on the lower end. The term bore as used herein is not limited to having a round transverse cross section. The center of the bores 33 are spaced from the center of the wick 15 a distance sufficient to allow volatilization of scent producing components in the elements 31 from the heat of the flame 21. This distance D, FIG. 2, is on the order of about and about . The bores 33 can be formed by any suitable method, such as drilling after the body 12 is formed or molding during forming of the body 12. The bores extend generally parallel to a longitudinal axis of the candle body, generally meaning within the bounds of the outer diameter of the candle. Preferably, the transverse cross-sectional shape of the bores 12 is generally round, although other shapes can be provided if desired. When round, the diameter of the bores 33 would be on the order of about and about . Other shapes should provide the same cross-sectional area as the above described round bores 33. Preferably, the bores 33 are closed at the ends thereof, adjacent the lower end 18. It is to be understood that the bores 33 could be provided with a liner 34, as shown in FIG. 2, if desired.

(11) In a preferred embodiment, the scent elements 31 are in solid form at room temperature. As shown, they are in the form of a generally round rod and fit within the respective bore 33. They can be placed in the bore 33 by the user and can provide the same scent in each, a different scent in each, or a combination of the same and different scents as selected by the user. The scent contained in an element 31 can be volatilized by the heat of the flame 21. Preferably, the elements 31 are consumed by the flame 21 during use. One scent element 31 found to be usable is a high scent oil containing wax, having a low melting point. A scent element 31 is preferably smaller than the bore 33 so that a user can simply install them or remove them as desired. This allows for a user to select one or more desired scents, or a no scent element, when burning the candle 11, and to change the scents for another candle burning session. In at least one alternative embodiment, the elements 31 melt into place and mix with the wax from the body 12. While the scent element 31 is described above as being in solid form, it is to be understood that a liquid form of scent element 31 can be used. This can be accomplished by simply pouring a liquid scent into a bore 33. As the candle 11 decreases in length during burning, the scent elements 31 will be consumed by the flame 21. It is to be understood that a scent element 31 in solid form can have different scents provided along different sections of the length thereof. It is also to be understood that an element 31 can be in the form of a liquid (at room temperature) scent material 35 encapsulated initially in a solid closed shell 32; the shell being made of a material that will melt when the flame 21 is present to expose the scent material to the flame heat for volatilization and release, FIG. 7. The encapsulated liquid is denoted as a solid by encapsulation to differentiate it from a fully solid element 31. A suitable shell material can be a tristearin that is solid at room temperature, but will melt in the presence of a candle flame 21.

(12) FIG. 5 illustrates a candle 11 having bores 33 of various transverse cross-sectional shapes. Bore 33A is rectangular, bore 33B is arched, bore 33C is triangular, and bore 33D is star shaped. These shapes can be used to designate a particular scent if desired. The bores may all have a like shape or they may all be different with respect to each other without departing from the scope of the invention.

(13) FIG. 4 provides a graphic representation of a temperature profile of a candle flame 21. As can be seen, the flame's temperature increases upwardly and outwardly, and then, outside the flame, the atmospheric temperature decreases exponentially with increasing distance. Thus, different volatile components for the scent elements 31 can be selected and positioned for improved performance. The bores 33 are shown as being an equal distance from the wick 15, but it is to be understood that additional bores can be provided at different distances from the wick 15 to accommodate different scents, such as bore 33E as shown in FIG. 2 in dashed lines.

(14) The candle body 12 and scent elements 31 can be sold in kit form or separately, and the user can configure the candle 11 in any desired configuration.

(15) It is to be understood that while certain forms of the invention are illustrated, it is not to be limited to the specific form or arrangement herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention, and the invention is not to be considered limited to what is shown and described in the specification and any drawings/figures included herein.
