An incombustible wick (11) for a flammable mass operated light, said wick (11) having a cylindrical elongate configuration with an internal cavity (10) and fiberglass material, characterized in that said wick (11) has an interior cavity (10) first fiberglass wrapper assembly (8) having a first basis weight fiberglass material and a second glass fiber wrapper assembly (13) having a second basis weight surrounding the first fiberglass wrapper assembly (8).

Description

The present invention relates to an incombustible wick for a flammable mass operated light, the wick having a cylindrical elongate configuration with an internal recess and fiberglass material, according to the preamble of claim 1. The invention further relates to a flammable mass container and at least A wick according to claim 6 and an arrangement comprising a container and a body separated from the container with flammable mass according to claim 7.

Such an incombustible wick is intended for a light operated with combustible mass, wherein the combustible mass may be, for example, wax or wax residues, which are supplied to the light or the wick. Through the inner recess of the wick, a capillary effect is achieved, which ensures that the combustible mass rises in liquid form in the direction of the flame burning at the upper end of the wick and burns there as gas. This description makes it clear that the inner recess has a function necessary for the burning of the flame and that clogging of the inner recess leads to extinguishment of the flame.

Based on CH 134483 A For example, a Wickeldocht for a spirit burner with a liquid-absorbing internal material and a wound around it incombustible material has become known.

The DE 69916187 T2 also describes a wick formed from fiberglass material.

The DE 20 2009 003 812 U1 describes a wick made of a fiberglass material which is inserted into a metal sleeve and which has been found to tend to clog the wick structure and prevent combustible mass from being fed to the flame.

The DE 3113067 A1 describes a wick insert with a metallic tube having an inner second and a third metallic tube, wherein the second tube has on its upper side metallic Wärmeleitstreifen. In the wick insert, a wick can be used, which must be pulled up to compensate for a burned wick section. When the wick has finally burned out completely, a new wick insert with wick must be used.

Finally, that describes DE 10 2006 056 301 B4 a wick with a core of metal and a surrounding fiberglass material. The metal core of the wick tends to clog and, moreover, an organic adhesive is needed to form the wick, which can become brittle by the heat of the burning flame, so that the wick can dissolve. In addition, this known non-combustible wick is expensive to manufacture due to its design with a metal core and the mentioned organic adhesive and a sophisticated wick holder.

Proceeding from this, the object of the present invention is to provide a cost-effective to manufacture and simply constructed incombustible wick, which avoids the disadvantages described above. It is also intended to provide a container with a combustible mass and at least one wick according to the invention.

The invention has to solve this problem with respect to the wick on the features specified in claim 1. Advantageous embodiments of the wick are described in the further claims.

Finally, the invention has the features specified in claim 6 with respect to the container.

The invention provides an incombustible wick for a flammable-mass operated light, the wick having a cylindrical elongate configuration with an internal recess and fiberglass material, and the wick having a first fiberglass wrap structure having a first basis weight fiberglass material and a first fiberglass wrapper having the interior recess surrounding second glass fiber wound construction with glass fiber material having a second basis weight.

The inner recess is thus formed by the first glass fiber wound structure and has no metal insert, which tends to clog. Clogging of the well-known wick with metal insert, which is actually intended to maintain the capillary action to promote flammable mass in the light towards the flame at the top of the wick, is particularly evident when colored wax residues in the form of candle remnants are replenished because the dyes tend to close the inner recess of the metal insert, which ultimately stops the capillary action and the flame goes out.

The construction according to the invention of the wick with a first glass fiber wound construction with inner recess and the first glass fiber wound construction with glass fiber material with a first Surface weight is formed and a second glass fiber winding structure with a second basis weight surrounding the first glass fiber winding structure ensures that the heat emitted by the flame due to the insulating effect of the second glass fiber winding along the wick according to the invention in the direction of the surrounding the wick combustible mass is passed and this melts and capillary action generated in the direction of the flame with the inner recess formed by the first glass fiber winding structure is transported in the direction of the flame and the flame thus receives replenishment of combustible mass.

Because of its first basis weight of fiberglass material, the first fiberglass wrapper ensures that the inner cavity does not collapse unless liquid combustible mass is replenished from the outside, eg, colored candle remnants, with the first basis weight selected so that the first fiberglass wrapper has sufficient rigidity against the first fiberglass wrapper Collapse of the inner recess or capillary has and the inner recess remains dimensionally stable even after long operation of the light according to the invention. On the one hand, the second glass fiber winding structure provides for the already mentioned insulation effect and on the other hand that burning of individual glass fibers of the first glass fiber winding structure that is not protruding from the second glass fiber winding structure can be avoided, and thus the incombustible wick according to the invention not only functions but also has long-term stability can maintain.

According to a development of the invention, it is provided that the weight per unit area of the first glass fiber winding structure is greater than the basis weight of the second glass fiber wound structure. In other words, the basis weight of the fiberglass material provided to form the first fiberglass wrapper is greater than the basis weight of the fiberglass material provided to form the second fiberglass wrapper.

The higher basis weight ensures that the stiffness of the fiberglass material of the first glass fiber package is sufficient to avoid collapse of the inner recess and provide a capped cap with sufficiently large inner diameter, while the lower basis weight of the glass fiber material of the second glass fiber package provides for that the glass fibers of the first fiberglass material are enclosed in the glass fiber wound structure and therefore on the one hand not projecting outwardly and thus can not burn and on the other hand, the desired cylindrical elongated configuration of the wick according to the invention can be maintained even after prolonged use.

It is also contemplated by the invention that the basis weight of the first fiberglass material be 100 grams per square meter to 600 grams per square meter and the basis weight of the second fiberglass material be 10 grams per square meter to 100 grams per square meter. In one embodiment, the basis weight of the first fiberglass material is about 200 grams per square meter while the basis weight of the second fiberglass material is about 30 grams per square meter. These basis weights have proved to be advantageous for the combustion image of the flame and for the long-term stable shape and function of the wick according to the invention.

According to a development of the invention, it is also provided that the wick has at least one enclosure on the outer circumference, which prevents an automatic opening of the glass fiber wound structure. This enclosure may, for example, be a simple wire loop wrapped around the outer perimeter of the second glass fiber package, such that the open end of the planar portion of the fiber material of which the second fiber package is formed may not open automatically. Instead of a wire loop, an incombustible cord, a wire helix, a wire spring or the like can be used, each of which ensures that the free end of the glass fiber material of the second glass fiber wound structure is not radially protruding.

According to a development of the invention, it is also provided that the wick has at one end region a mass body surrounding the glass fiber wound structure. The mass body can be, for example, an internally threaded nut whose inner diameter is approximately equal to the outer diameter of the wick, so that the nut can be screwed onto the end portion of the wick as it were, resulting in a weighting of the wick, so that it does not tilt to the side when it is positioned in a container for holding combustible matter and, on the other hand, is achieved in that the end region of the wick provided with the mass body does not open automatically. The use of a commercially available hexagon nut offers the advantage of a sufficiently mass-laden weighting of the wick and, moreover, the advantage of a very cost-effective design.

The incombustible wick of the invention can be made as follows:

• - Providing a first planar portion of a glass fiber material having a first basis weight
• - Providing a second planar portion of a glass fiber material having a second basis weight
• - Providing a provided with a longitudinal slot winding bar
• - Introduce the first flat portion in the slot of the winding rod
• - Turning the winding rod about its longitudinal axis to provide a first glass fiber winding structure with a free unwound surface portion
• - Arranging the second flat portion on the free unwrapped surface portion
• Rotating the winding rod about its longitudinal axis to provide a second glass fiber structure enclosing the first fiber structure;
• - Remove the winding rod.

Thus, a first planar section of the first glass fiber material is first provided, which may be, for example, a glass fiber mat with a basis weight of 200 grams per square meter. Next or at the same time, a second sheet portion of a second basis weight fiberglass material is provided, which may be, for example, a glass fiber nonwoven having a basis weight of 30 grams per square meter.

Also provided is a winding bar provided with a longitudinal slot, the longitudinal extent of the slot corresponding to the widthwise extent of the first areal section which can then be inserted into the slot. By rotating the winding rod about its longitudinal axis, the first areal section is then wound to the first glass fiber winding structure until such time as an uncoated free area section remains stationary. Then, the second planar portion is placed on the unwrapped free surface portion such that rotation of the wound rod about its longitudinal axis causes the overlapping portion of the second planar portion to come to rest between the first glass fiber coil assembly and the still unwound free surface portion and rotate the winding rod then causes the first glass fiber package to be trapped by the second glass fiber package from the second sheet section. In this way, the second glass fiber winding assembly completely surrounds the first glass fiber winding assembly and the first optical fiber material is completely enclosed by the second fiberglass material.

In a next step, the winding rod is then removed and there remains an inner recess in the wick thus formed, which forms the capillary of the wick according to the invention.

At least one skirt of incombustible material may be disposed prior to removal of the winding bar on the outer periphery of the second glass fiber structure, which prevents self-opening of the second glass fiber winding structure. The enclosure can be, for example, a wire loop or a section-wise covering of the glass fiber wound structure of an incombustible material.

Also, prior to removal of the winding rod at an end portion of the second glass fiber winding assembly, a mass body enclosing the glass fiber winding assembly may be arranged, which may be, for example, a commercially available hex nut, which on the one hand ensures that automatic opening of the end portion of the glass fiber winding assembly is avoided and, on the other hand due to the mass of the hex nut a stable state of the wick according to the invention is achieved in a container for receiving combustible mass.

Finally, the invention also provides a container having a combustible mass and at least one wick as described above, wherein the wick has a free end projecting over a surface of the combustible mass. The combustible mass may be, for example, wax, stearin, lots, beeswax or even fat, ie a mass which includes the wick according to the invention, in such a way that a flame-free end protrudes above the surface of the combustible mass ,

After igniting the flame, the flammable mass melts and a light burning with an open flame is generated, which corresponds to a plurality of individual candles from the luminosity and combustible mass in the form of, for example, candle residues, wax residues or the like can be refilled at any time, the Nachfüllmasse must therefore not be refilled in liquid form, but can be refilled, for example in the form of wax pads or candle residues or the like.

Such, also provided according to the invention arrangement, thus has a container with combustible material and at least one wick and is also characterized by a separate from the container body with combustible mass, which is provided for refilling the container.

2 The drawing shows a second area section 2 glass fiber nonwoven fabric also having a predetermined width B and a predetermined length L1 of about 125 mm extending from the length L of the first sheet portion 1 differs in that the length L corresponds to about 3.2 times the length L1, these dimensions are selected according to the diameter of the finished wick accordingly. The weight per unit area of the glass fiber fleece in the illustrated embodiment is 30 grams per square meter.

The two flat sections 1 . 2 can be cut from prefabricated glass fiber material webs, wherein the width B of the length L2 of the slot 3 of the winding rod 4 corresponds to that in 3 the drawing is shown and in the illustrated embodiment has a diameter of about 6 mm, with a length L2 of the slot of 70 mm. The winding rod may have a diameter of about 2 millimeters to about 20 millimeters.

After the two plane sections 1 . 2 is made, the glass fiber mat 5 in the slot 3 of the winding rod 4 introduced and that until, by turning the winding rod 4 about its longitudinal central axis 7 around a first fiberglass wrap construction 8th can be created as he is in 7 the drawing is shown schematically. With the arrow 9 to 7 is the direction of rotation of the winding rod 4 shown, where 7 also shows that the winding rod 4 in the first fiberglass wrap construction 8th a closer on the basis of 8th the drawing apparent inner recess 10 which produces the capillary of the finished wick 11 equivalent.

7 the drawing shows that the glass fiber fleece 6 even before the final completion of the first fiberglass construction 8th on a free, unwrapped surface section 12 the fiberglass mat 5 is placed in such a way that by the further rotation of the winding rod 4 in the direction of the arrow 9 the glass fiber fleece 6 then the first glass fiber wrap construction 8th completely encloses and with the glass fiber fleece 6 by turning the winding rod 4 the second glass fiber wrap construction 13 is generated, the first glass fiber winding construction 8th completely surrounds or encloses.

This configuration is in 8th the drawing shown, which the already completed wick 11 in a sectional view shows and that with the inner recess 10 , which is achieved by the winding rod 4 after completion of the second glass fiber winding construction 13 or after completion of the wick 11 from the wick 11 is pulled out.

Even before the winding rod 4 but from the wick 11 is pulled out, an in 5 The drawing schematically illustrated double rod binding wire 14 to one in 6 illustrated pre-wound binding wire 15 deformed, which can be done for example by means of a drill or a pair of pliers for winding a safety wire.

At the in 8th illustrated embodiment of the wick 11 are two binding wires 15 in the axial longitudinal direction of the wick 11 spaced apart on the outer circumference of the wick 11 been arranged and the free end 16 of the binding wire 15 towards the lower end section 17 the wick 11 bent over, the two binding wires 15 Make sure that the free end 18 of the glass fiber fleece 6 the wick 11 does not automatically open and so does the cylindrical configuration of the wick 11 preserved.

8th The drawing also shows that at the lower end 17 the wick 11 already based on 4 described hex nut 19 , which in the illustrated embodiment is an M16 nut, has been arranged in such a way that the nut 19 over the end section 20 of the winding rod 4 pushed and with the lower end section 17 the wick 11 is brought into contact and then by simply turning the nut manually 19 the internal thread of the nut 19 makes sure that the mother 19 on the lower end section 17 the wick 11 unscrewing. In this way, an additional fixation of the free end portion 17 be achieved, leaving the free end 18 of the second glass fiber construction 13 is secured against self-opening and, moreover, by the mother is a simple weighting of the wick 11 reached.

After the wick 11 according to the 8th has been formed, the winding rod 4 from the middle of the first fiberglass construction 8th be pulled out leaves behind and acting as a capillary inner recess 10 ,

9 The drawing shows a schematic representation of a container 21 in the form of, for example, a clay pot with a wick in the middle 11 with the hex nut 19 as a weighting has been arranged and a combustible mass 22 has been filled in the form of a wax. The wick 11 has a supernatant 23 that over the surface 24 the combustible mass 22 stands out and where the wick 11 can be ignited for example by means of a lighter. By the heat of the then adjusting, not shown flame on the supernatant 23 The wax melts and becomes via the acting as a capillary inner recess 10 towards the supernatant 23 promoted and burns there as a flame.

Depending on how long the wick 11 Already ignited, an ever larger area of the combustible mass melts 22 around the wick 11 around and becomes liquid and in the already liquid area or a liquid becoming area flammable mass in the form, for example, of candle remnants or wax pads are laid, so provide a supply of combustible mass and melt due to the heat of the flame and then again as combustible mass are available.

The wick of the invention can be operated with all waxes on the market, it does not burn off, it has been shown that it can even be operated with fat in the form of frying fat, it can be operated with residual wax and candle residues of any kind and clogged also not by the colorants contained in colored candles or colored candle residues.

The wick can generally be made in different lengths and diameters, depending on the need and the size of the container thus provided for receiving combustible mass. It is also possible to provide a container with a plurality of wicks according to the invention, so that a light with very high luminosity can be created. About the height of the supernatant above the surface of the combustible mass 22 the height of the flame can be influenced.

In contrast to known lights with incombustible wicks the refill material of combustible mass must not be refilled in liquid form, but candle residues, wax residue or the like can be placed in a solid state to the edge of the flame of the wick and the heat of the flame melts the refill material automatically and the vessel or container refills with flammable mass. It has been found that the flame achievable with the wick according to the invention does not extinguish even in stronger wind, light rain and light snowfall, and therefore the light equipped with the wick according to the invention is ideally suited as outdoor light.

Even if the user were to fail to add flammable mass and the light goes out due to lack of flammable mass, this will not damage the wick of the present invention since the user then only flammable mass before the next time the light is used in liquid form must fill in the provided with the wick container and the user can then re-ignite the wick.

With regard to the above in detail not explained in detail features of the invention, reference is expressly made to the claims and the drawings.
