Description

The invention relates to a candle, a manufacturing method of such a candle and a combination of a candle and a holding device.

Are known candles with wick areas constructed with a flat metal plate, which is attached to the candle bottom.

The disadvantage is that such a device does not provide sufficient security against leakage of the wax or a temperature transfer in an area adjacent to the candle area. The precautions also limit the design options and overall the aesthetic effect of a design with such candles.

WO 03/016443 A shows a wick holder made of a non-combustible plastic material having a bore into which the wick is inserted. The disadvantage is that by the Höherstellung the wick alone sufficient security for the candle is achieved, so that, for example, a burning without a surrounding container carries an unacceptable risk.

WO 02/33315 A shows a candle with a wick holder in a candle vessel which, however, has no security against burning.

EP-A1-1 054 054 shows a candle on a plate (display) with a wick holder with a substantially open edge, which has the goal of a minimum distance of the wick from the plate, since as complete as possible wax consumption is to be achieved.

The disadvantage is the not guaranteed security, if the candle should be operated without a plate.

US-B1-6 220 855 shows a candle that stands on a raised holder with a spinous process. The disadvantage is that wax drips down in larger quantities and poses a safety risk.

It is an object of the present invention to easily ensure a secure holder for candles.

It is a further object of the invention to provide the tightness of a holder for candles against the leakage of wax or against the spread of candle fire.

It is a further object of the invention to provide a holder that prevents the falling of the wick and a spread of candle fire.

It is a further object of the invention to bring the aesthetic effect of a candle to full advantage, without having to accept restrictions or compromises in the aesthetic design options.

These objects are achieved by a candle having a wicking area, wherein the wicking area has a wicking insert with a wick mounting area and a clearance area for maintaining a predetermined distance to a candle bottom of the candle, the spacing area of the wicking insert being formed with a cavity open to the candle bottom is, wherein the wick is squeezed in a frictional shape in the mounting area.

The invention offers the advantage that a safe self-extinction of the candle is ensured in a simple manner. In addition, leakage of wax candle or removal of the wax is prevented below a predetermined height in the vicinity of the wick of the candle, since the wick extinguished in the attachment area and the isolation through the distance range no further wax can be tightened. The candle is universally usable with various holding devices, for example, both for a holder with an annular side wall and for a conventional metal holder with retaining pin. A fast and very durable attachment of the wick at a predetermined height is ensured when the wick is fixed in a non-positive form in the mounting area, in particular squeezed.

Overall, the wick is higher than the holding area, so that the wick is not supplied with new wax when falling below a certain residual amount of existing wax. In particular, the edge is not liquid. The invention achieves the advantages without departing from the design, d. H. especially in the artistic-aesthetic design of a candle, especially with flower arrangements, to make compromises or give up design freedom. The invention makes it possible, in particular, to adequately present a candle or several candles in a arrangement or in an Advent wreath without aesthetic restrictions, wherein all known holders for candles can be used, in particular also a device with holding mandrel in the region of the wick. The wicking insert also secures the wick against falling over.

Advantageous embodiments of the present invention are specified in the subclaims.

A good fit of a retaining pin of a holding device is given when the cavity is filled with a plastically deformable material, in particular with wax. An inserted into the cavity retaining mandrel can thus be held by the laterally stuck plastically entombable but sufficiently stable material.

A simple insertion of a retaining pin and a secure hold of the wick area in the candle is given if the distance range has a spreading in the direction of the candle bottom area.

A very leak-proof and stable combination of candle and fixture is provided when a retaining mandrel of a fixture of the candle is to be inserted into the cavity of the spacer portion of the wick support insert.

A simple and secure device is provided when the wick-holding insert is designed as a sleeve radially enclosing the wick in the longitudinal direction. In this way, for example, the attachment region and the distance region can be formed in one piece.

It is advantageous if the wick-holding insert is made substantially in one piece from a heat-resistant material, in particular from heat-resistant plastic, in particular polycarbonate or polyetheretherketone. In this way, the wicking insert can be integrally formed, wherein the attachment of the wick in the attachment area, for example, by gluing with a heat-resistant adhesive can be made.

It is advantageous if the wicking insert made of metal, in particular zinc-plated copper, in the attachment area and made of plastic, in particular polypropylene, in the distance range. The attachment area can thus be brought into holding contact with the wick by a crimping pressure, while the plastic provides insulation against a transfer of heat.

It is advantageous if the wick-holding insert has a heat-resistant material which has a low coefficient of heat conduction, ie. the specific thermal conductivity, which is in particular smaller than metallic heat conduction coefficients, and in particular less than 10 W / Km, more particularly less than 1 W / Km, more particularly between 0.1 and 0.9 W / Km, and more particularly between 0.1 and 0.3, in particular about 0.2 W / Km. In this way, a good and reliable thermal insulation is given.

An advantageous additional safeguard against leakage of the wax is provided when the candle is provided with a bottom-side, annular groove-shaped recess whose recess geometry is intended to correspond to and receive the side wall of a corresponding holding device, the recess being designed in particular that the candle is held tilt-proof under the conditions of use and liquefied candle material is retained by the holding device.

Characterized in that the holding area surrounds at least the wick area of the candle in the candle bottom, and in that the holding area essentially cup-shaped closed, the leakage of candle wax and the spread of candle fire is reliably prevented. It turns out that only the periphery of the wick area melts, because there of course takes place the largest heat input through the candle flame. This is a "hidden" holding area, which is virtually or barely visible when using the candle, yet large enough and safe enough to catch (expiring) candle wax safely and prevent the spread of candlelight safely.

A simple and fast and reliable production is possible if the plug body together with the recess for inserting the wick and the wick-holding insert urgeformt, in particular pressed or poured or dipped is.

A simple and fast and reliable production is also possible if the plug body together with the recess for the insertion of a side wall of a holding device urgeformt, in particular pressed or poured or dipped is. This is particularly advantageous in connection with the shaping of the recess for inserting the wick and the wicking insert. This is a practically one-step manufacturing process, which is very simple, given to make the candle body and it is a special tool for archiving practically not needed.

A simplified production is possible when a surface coating is applied to the plug body by dipping, wherein the plug body is immersed together with the recess / recesses, and in the candle body before diving introduced recess / recesses is / are dimensioned such that the final Ausnehmungsgeometrie, in particular the width of the recess / recesses, only results from the surface coating.

This means, in particular, that the thickness of a resulting surface coating already takes into account the design or the design of the plug body. This allows the candle body completely - especially with the candle bottom together with the recess - are dipped, so that a simple dipping process is achieved.

The above-mentioned objects and advantages are also achieved by providing a candle according to one of claims 1 to 11 according to the manufacturing method according to claim 12 , wherein the recess is milled out of the wax or the candle into a mold with a correspondingly formed Recess is pressed or poured, in which case a wick is used with a wick holder insert, and in particular subsequently the cavity of the wick holder insert is filled with a plastically deformable material, in particular with wax.

The above objects are also achieved by a combination of a candle according to any one of claims 1 to 11 and a holding device with a holding mandrel for insertion into the cavity of the wick holder insert and / or a closed holding area with an annular side wall wherein the holding device on a bottom side facing away from the candle in particular has a fastening device by means of which the holding device in a mounting region of a Kerzenträgers, for example a ring, is to be attached. The holding device shown here in a mounting region of a Kerzenträgers, such as a wreath is to be attached. The holding device shown here and a correspondingly shaped candle with an annular shape should also be used without a wick area shown above, for example as a holding device of a candle, with a substantially cup-shaped closed holding area with an annular side wall, wherein the holding area is provided that the candle with a side wall receiving and this at least over a part of its height surrounding recess of its candle base is inserted into the holding area and is held positively and / or non-positively on the side wall of the holding area, and that the holding area at least one wick area of the candle in the candle bottom surrounds and the outer diameter of the side wall is formed smaller than the outer diameter of the candle.

The candle has, for example, a bottom-side, annular groove-shaped recess whose recess geometry is intended to correspond with and receive the side wall of the holding device, wherein the recess is designed in particular such that the candle is kept tilt-proof under the conditions of use and liquefied candle material is retained by the holding device is. It can also be provided that the holding device is partially visible. It can also be provided that the holding device is largely or completely practically invisible within the candle.

Preferably, the bottom of the inner cylindrical portion is recessed from the bottom of the outer annular portion, preferably substantially one to two times the thickness of the bottom of the holder, so that the holder is also in side elevation of the candle practically completely disappears within the candle, d. H. is substantially hidden by the projecting, outer, annular region.

Advantageously, the candle according to the invention can also be used for a combination with a bottomless holding device, wherein the holding device has a plurality of decentralized fixing mandrels for insertion into the candle bottom outside the wick area.

Fig. 1a shows a cross section through a candle 2 according to the invention with a wick holder insert 51. The wick holder insert 51 has a fastening region 52 for fastening the wick 26 and a spacer region 53 for establishing a safe distance 54 of the end of the wick 26 from the candle bottom 9. The spacing region 53 in turn has a cavity 55 through which, as in FIG Fig. 1b shown, a retaining pin 57 may protrude into the wick holder insert 51. Due to the inventive design of the candle can be prevented that the wick 26 burns too far into the candle base of the candle 2, thus damaging a possibly flammable or temperature-sensitive substrate. The wicking insert 51 is shown here as being inserted in a recess of the candle 2 at the bottom area and connected to the wick 26 at its fastening area 52, in particular it is crimped. The spacing portion 53 prevents the wax from warming up and becoming liquid in the area below the crimped wick 26, and thus also preventing the wicking area 10 from coming off and being able to slip downwardly in the absence of, for example, a plate-shaped holding device.

Fig. 1b shows a cross section through a candle 2 according to the invention with a holding device 1 with a retaining mandrel 57. The retaining pin 57 protrudes into the Hollowing 55 of the wicking insert 51 in without affecting the level of the candle 2. If the wicking insert 51 is also filled, for example, with wax, a secure holding of the candle 2 is ensured by the retaining mandrel 57. At the same time, the candle 2 is securely formed by the self-extinguishing function of the wick region 10.

Fig. 1c shows a cross section through a candle 2 according to the invention with a holding device 1 with a retaining mandrel 57, wherein for mounting in the ground, for example a wreath additional sockets 17 are provided.

Fig. 1d shows a cross section through a candle 2 according to the invention with a bottomless holding device 1 with a plurality of fixing mandrels 58. The candle 2 according to the invention can not be dangerous to the environment after burning until the self-extinguishing of the wick 26, since the wax in almost the distance 54 of the wick 26 to the candle bottom 9 corresponding height stops. This height is schematically indicated by a traversing corrugated line in the plug body.

Fig. 2 shows a cross section through a candle 2 according to the invention with a height 5 with an annular recess 6 for holding the candle 2. The candle 2 is additionally protected by the side wall 4 of the holding device 1 against leakage and at the same time kept invisible and safe from the outside.

Fig. 3 shows a perspective view of a wicking insert 51 of a candle 2 according to the invention. The wicking insert 51 has at its lower end in the spacing region 53 a widened region 56 a cavity 55. In the upper attachment portion 52, the material for holding the inserted wick 26 is squeezed.

Fig. 4 shows a cross section through a wick holder insert 51 of a candle 2 according to the invention and Fig. 5 shows a cross section through a wick support insert 51 of a candle according to the invention 2. The wick holder insert 51 has a mounting portion 52 and a distance portion 53 with an enlarged portion 56 with a cavity 55 so that, for example, a retaining pin 57 can protrude into the mandrel holding insert 51 and at the same time the candle is self-extinguishing. For example, a diameter 59 of the attachment region 52 may be approximately 0.5 mm to approximately 15 mm in size, in particular adapted to the wick 26, and a diameter 60 in the clearance region may be approximately 2 mm to 25 mm. In this way, a large diameter range and different candle sizes can be covered.
