| Claims A candle (1) in a metal box, comprising a metal box (2), the body of the candle (3) together with the wick (4), characterized by thermal insulation (6) attached to the bottom of the metal box (2) for the whole perimeter of the bearing surface of the candle (1), in order to ensure complete burning of the body of the candle (3). |
FIELD OF THE INVENTION
The present invention relates to the domain of tea light candles and outdoor candles, where the body of the candle is placed in a thin-walled metal box of any shape and design.
BACKGROUND OF THE INVENTION
The matter of safety, particularly at the end of burning, has been considered the main drawback of the traditionally marketed candles so far. For example, an overheated metal box may burn a hole in a wooden surface, or even start a fire if left unattended, in case the flame can be spontaneously transferred to the solid fuel due to overheating. In order to avoid such spontaneous combustion, a safe conical bottom of the box (US6398544, published 18.10.2001) has been invented, for instance, which helps to avoid both risks to a certain extent. At the same time, this construction does not solve the problem of incomplete burning of the candle body caused by the metal box in cases where the heat necessary to melt the body of the candle is transferred via the metal box, which is a good thermal conductor, to the bearing surface of the candle with good thermal conductivity qualities (metal, glass, ceramics, concrete, stone, etc.).
BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to solve the latter problem in a practical and economical manner. This object will be gained by thermal insulation attached to the bottom of the metal box that surrounds the body of the candle together with the wick and the wick fastener. The thermal insulation is attached at least to the surfaces of the bottom of the metal box that come into contact with the bearing surface of the candle. Candles with thermal insulation can be used independently without having to resort to special candle holders. BRIEF DESCRIPTION OF THE DRAWINGS
The technical essence of the invention is explained by the following drawings: FIG 1 - assembly of the candle in the metal box;
FIG 2 - the candle in a metal box without thermal insulation after the candle has gone out.
FIG 3 - the candle in a metal box with thermal insulation after the candle has gone out.
EMBODIMENT OF THE INVENTION
Figure 1 shows the assembly of the candle 1 in a round metal box with a flat bottom, comprising the metal box 2, the body of the candle 3, the wick 4 and thermal insulation 6.
Figures 2 and 3 further show the notional residue 7 and 8 of the wick fastener 5 and the body of the candle 3 in a candle without and with thermal insulation respectively, after its spontaneous extinction. The thermal insulation 6 enables the preservation of the temperature necessary for the optimum melting of the body of the candle 3 within the wall of the metal box 2 until the end of burning, thus ensuring maximum complete burning of the body of the candle, which is the object of the present invention.
