Description

Wick support with and without wick bridge and/or dispensed and/or portionable refill fuel without wick, particularly for long-term tea lights, grave lights and candles with and without containers.

State of the art

With the tea lights known to date in containers that serve to hold the liquid wax when it burns, there is a very high risk that as soon as the wax has been completely or partially liquefied by the heating and can therefore no longer support the wick, the wick will fall over and the flame will go out. This can happen after just a short burning time, and the tea light will then become unusable, even though most of the burning mass is still there.

With tea lights that are extinguished after they have partially burned out, it often happens that after being lit again, the wick burns down and the flame then goes out because the surrounding fuel cannot liquefy and therefore does not rise into the wick. In this case too, the tea light is unusable, even though a large part of the fuel is still there. Even if the economic damage is small in individual cases, it is very unpleasant but overall it has a significant environmental impact due to the large number of tea lights and grave lights used, because around 20 to 30% of the fuel is thrown away unused along with the container.

Description

To eliminate this disadvantage, it is suggested to support the wick. This support can preferably be provided by a vertically arranged spiral. This spiral preferably has a winding distance of approx. 3-5 mm and an inner diameter that is approx. 0.5 mm larger than the outer diameter of the wick. The wick can also be wrapped in the spiral and thus fixed in its vertical position. In order to reach the rest of the burning mass during burning, the wick must touch the bottom of the vessel with its lower end, but preferably be bent so that several mm of the wick are on the bottom of the vessel. The upper end of the wick can preferably protrude several mm beyond the tip of the wick support.

The support device can also consist of a vertically arranged piece of pipe with openings or slots and/or of vertically arranged strips or columns. It can be firmly connected to the bottom of the vessel and/or held by a device on or in the bottom of the vessel.

Preferably, however, the support device is provided with its own base, whereby the support device and base can consist of one part or several parts. If a spiral is preferably used, the base can preferably consist of an increase in the winding diameter in the lower area. Depending on requirements, the support devices can consist of a combustible or meltable material with good or poor thermal conductivity, as well as a non-combustible material with good or poor thermal conductivity, but preferably of heat-resistant material to ensure multiple use. The height of the wick support depends on the height of the wax vessel, the tip can be above the upper edge of the vessel, but preferably it is below the upper edge of the vessel. In particular with tea lights, grave lights and candles with and without vessels, the rapid liquefaction of the fuel mass when lighting, especially in the immediate vicinity of the wick, is necessary to prevent the wick from burning separately. The wick support consists of

in this case preferably made of a good heat conductor. On the one hand, the wick remains stable during burning, and on the other hand, the wick holder is already heated when it is lit, and the flame continues to heat it up. The heat is passed on through the wick holder downwards into the initially solid fuel mass. This creates a thermal bridge downwards, which immediately liquefies the fuel mass and thus causes it to flow to and into the wick.

This eliminates the previously common pitting of solid fuel on the edges of the vessel, and after just a short burning time a large part of the upper fuel is liquid and forms a flat surface.

Even if the combustion is interrupted several times, there is hardly any hollow formation and the fuel mass can be used until the last residue.

This measure not only ensures maximum use of the fuel but also maximum use of the wick. The wick support extends the service life of the wick considerably beyond the initial fuel in the container. This makes it possible to add additional fuel in the form of candle remnants or special refill fuel. This not only ensures that the original fuel is completely used, but also enables the sensible use of remnants and cheaper refill fuel, which contributes to environmental protection as well as bringing financial benefits. In the case of tea lights in particular, the environmental impact is reduced to less than 5% of the current level.

Even after the fuel and wick have completely burned out, the wick support and the container can be used again after a short cleaning. By inserting a new wick and adding new fuel, the advantages described above can be used again. Especially with tea lights, the environmental impact is reduced to less than 2% of the current level.

For vessels made of a material that does not or poorly conduct heat, it is best to place a foil that conducts heat well between the fuel and the vessel so that the entire fuel can liquefy. For relatively tall vessels, the wick support with base can also be melted into the fuel and sink as the combustion progresses until it finally rests on the bottom and ensures complete combustion.

With the help of the wick support, vessels with a larger diameter and higher than usual and with several burners can also be used. Such vessels can be used primarily for preparing fondues and hot punch or for keeping larger quantities warm, as a replacement for the previously known and used spirit burners, whereby the risk of accidents is reduced to an absolute minimum compared to spirit burners.

However, wick supports are also possible in and/or on the wick. The wick can also be prevented from falling over by a rigid core incorporated into the wick or by a core running alongside the wick that is connected to the wick at certain intervals.

The wick can also be separately impregnated with a suitable wax or plastic mass with a significantly higher melting point than the fuel mass, thus obtaining the necessary stability.

Especially for expensive candles with a large diameter, the wick support multiplies the service life.

The height of the flame and thus the burning speed is not determined or influenced by shortening the wick as before, but by adding additional fuel.

A partially burned wick in the support can easily be replaced with a new piece of wick in the support, thus contributing to a significant extension of the candle's service life.
