COMBINATION CANDLE AND RECEPTACLE Filed March 28, 1968 United States Patent 3,493,314 COMBINATION CANDLE AND RECEPTACLE Casimir Krance and Thomas N. Moore, Oshkosh, Wls., assignors to Victrylite Candle Co., Oshkosh, W1s., a corporation of Wisconsin Filed Mar. 28, 1968, Ser. No. 716,864 Int. Cl. C11c /00 US. Cl. 431-291 4 Claims ABSTRACT OF THE DISCLOSURE A candle set into a glass receptacle, the side wall of which is shaped to provide a plurality of circumferentially spaced air entry flues having an upwardly and outwardly inclined orientation.

This invention relates to candles and more particularly to a combined candle and receptacle therefor.

For years, candles have been placed in glass receptacles. In some cases the candles were loosely set into the receptacle, but often they were molded into the receptacle so that the body of wax constituting the candle and the receptacle together constitued an inseparable unit. This was especially so with scented candles and insect repellant candles, the burning of which permeates the surrounding air with a scent pleasant to humans but obnoxions to insects, especially mosquitos.

Heretofore, the receptacles used in these candle-receptacle combinations always had their entire upper edges lying in a common plane normal to the vertical axis of the receptacle, and the open top of the receptacle seldom was much larger than the cross sectional area of the candle body. In the case of those candle-receptacle combinations in which the wax body was molded directly into the receptacle, there was no space between the side wall of the receptacle and the wax body.

This past construction had the disadvantage of poor circulation of air to and from the combustion zone which surrounds the flame of a burning candle, a disadvantage that became increasingly serious as the candle burned down and the level of the combustion zone dropped farther into the bottom portion of the receptacle. Not only did this condition interfere with proper combustion, but it also shortened the period during which a scented candle gave off its aroma.

With a view to overcoming, or at least greatly minimizing the aforesaid objections, it is an object of this invention to provide an improved candle-receptacle combination in which the receptacle is shaped and formed to provide air entry flues which lead from open mouths spaced a substantial distance from the combustion zone, to the bottom portion of the receptacle interoir to thus promote a positive and continuous circulation of air to and from the combustion ozne.

It is also an object of this invention to provide a candle-receptacle combination which not only assures improved combustion and better diffusion of the scent of the burning candle and for a longer time, but also has a very pleasing appearance.

With these observations and objectives in mind, the manner in which the invention achieves its purpose will be appreciated from the following description and the accompanying drawings. This disclosure is intended merely to exemplify the invention. The invention is not limited to the particular structure disclosed, and changes can be made therein which lie within the scope of the appended claims without departing from the invention.

The drawing illustrates one complete example of the physical embodiment of the invention constructed accord- 3,493,314 Patented Feb. 3, 1970 iCC ing to the best mode so far devised for the practical application of the principles thereof and in which:

FIGURE 1 is a perspective view of the candle-receptacle combination of this invention;

FIGURE 2 is a top plan view thereof; and

FIGURE 3 is a vertical sectional view through FIG- URE 2 on the plane of the line 33.

Referring to the drawing, the numerals 4 and 5 designate respectively the receptacle and candle portions of the combined candle and receptacle of this invention. The candle may be of the self-sustaining type consisting of a stubby, substantially cylindrical wax body 6 with a wick 7 protruding from its top surface substantially at the center thereof, or it may be a body of wax molded into the receptacle, but also with a wick protruding from its top surface.

The receptacle is preferably formed of glasseither clear or colored. It has a substantially fiat bottom wall 8 and a side wall 9 rising from the periphery of the bottom wall. The bottom wall is preferably, though not necessarily, circular, and the side wall 9 is shaped to provide a plurality of upwardly and outwardly inclined flues 10 extending from the bottom of the receptacle to upwardly facing open mouths 11. The flues are substantially equispaced around the perimeter or circumference of the bottom wall and are preferably even in number-four in the present instance. Accordingly, the flues are arranged in pairs, each diametrically opposite one another.

The portions 12 of the side wall which extend between the inclined fiues are substantially perpendicular to the bottom wall 8, and project a substantial distance above the level of the mouths 11. As best seen in FIGURE 2, the side wall portions 12 flanking each mouth contact one another or at least are contiguous so that air entering the mouths 11 is constrained to flow downwardly into the receptacle interior.

Since the months 11 are spaced farther from the vertical axis of the receptacle than any other part of the side wall, it follows that the temperature at the mouths-during burning of the candleis considerably lower than the temperature in the receptacle where the combustion zone is located. The combustion zone, of course, surrounds the flame of the burning candle, which because of the centered location of the wick, is substantially equispaced from the side walls.

The difference in temperature at the mouths 11 and at the combustion zone induces a positive and continuous flow of air into the mouths of the flues and through the flues into the lower portion of the receptacle interior, from which it flows to the combustion zone and supplies the same with ample oxygen for good combustion. It has also been found that this circulation of air improves diffusion of the aroma of scented candles, and lengthens the time for which a scented candle will give off its scent. This latter advantage may be due to the maintenance of a lower temperature directly above the molten pool and melting surface of the wax body as the candle burns, with the result that the perfume used to scent the candle is not destroyed by excessive heat before it can be released.

As the candle burns, the level of the combustion zone descends but this does not detract from the described circulation of air to and from the combustion zone. Even when the body of wax melts to the point where it loses its original shape and in effect forms a pool in the bottom of the receptacle, as shown in broken lines in FIG- URE 3, the air entry flues continue to function and serve their purpose.

But, most important, throughout the entire combustion period, that is the entire life of the burning candle, there is an enhanced diffusion of aroma into the surrounding atmosphere, providing of course that the candle is scented.

What is claimed as our invention is:

1. A candle device comprising a body of wax in a receptacle having bottom and side walls, the top of the wax body being at a level below the top of the receptacle and the wax body having a wick embedded therein and protruding from its top surface substantially at the center thereof, so that the combustion zone which surrounds a flame maintained at the wick is substantially equispaced from the side wall of the receptacle, said device being characterized by:

(A) the bottom wall of the receptacle being substantially fiat and circular;

(B) the side wall of the receptacle having a perimeter considerably larger than the circumference of the bottom wall; and

(C) the side Wall being folded upon itself at a plurality of circumferentially spaced locations to define a plurality of air entry flues spaced around the perimeter of the side wall,

(1) said flues extending from the bottom of the receptace interior with an upwardly and outwardly inclined orientation, and terminating at their upper ends in open mouths which are spaced farther from the axis of the receptacle than any other portion of the side wall,

so that the temperature at said mouths is considerably lower than the temperature at the combustion zone to thus promote the flow of air into and through said flues and the delivery thereof to the combustion zone regardless of its level in the receptacle, and (2) said flues being radially outward of the bottom wall so that the body of wax in the receptacle may be inserted thereinto in the form of a candle having a diameter equal to that of the bottom wall. 2. The candle device of claim 1, further characterized in that the folded portions of its side wall which provide the air entry flues are substantially equally spaced around the perimeter of the bottom of the receptacle. 3. The candle device of claim 2, further characterized in that the air entry flues are even in number and substantially diametrically opposite one another. 4. The candle device of claim 2, further characterized in that the portions of the side wall between the flues are substantially perpendicular to the bottom wall.
