Definitions
- the invention relates generally to a candle having a burn-through barrier, and to a method for the production thereof.
- Candles with burn-through barrier which must be distinguished from so-called * tealights are, for example, out DE 20 2006 002 696 U1 known.
- a candle plate is provided as a burn-through barrier whose dimensions are smaller than that of the candle body and which separates the wick from a base arranged thereunder.
- the candle plate is mounted in the area of the base of the candle and largely not visible in use, the candle plate can optionally be integrated into the candle, and there is largely hidden between the candle blank and a dipping wax layer, or in the form of a stick-on candle plate the Area of the base of the candle at most completely covered.
- a disadvantage of the known candle is in particular the fact that it is not recognizable as burn-secured after application to a flower arrangement, and that such a burn-through barrier can be provided substantially only in pillar candles, but not for example in pointed candles.
- the known candle provides cuts in an angle or half-moon shape in a plate of the burn-through barrier, which are bent over a straight line upwards or downwards; It is disadvantageous that the candle body displaced by its own weight, the folded-up portions completely back into the corresponding cutout in the plane of the plate, so that at best in a coating with dipping wax cut down the cuts improve the adhesion.
- the tealight envelope has a typical tealight dimension ratio of height to diameter of about 3: 4.
- DE 201 21 402 U1 describes a candle fire protection device in which a provided on the candle at the desired level of termination of the fire funnel-shaped attachment is filled with extinguishing agent and extinguishes the flame of the wick upon reaching a certain Abbrand Why.
- a disadvantage of this candle fire protection device is that the extinguishing agent has to be applied by hand, and that especially with an intended deletion in the area of the bottom surface of the candle burnout on below the candle located flammable objects is not excluded, since the middle area of the candle burns faster as the border area.
- US 2002/0022205 A1 shows a candle with a wick, which is surrounded by a candle body, and with self-extinguishing properties, so that it can be used in a non-flammable vessel made of glass or the like, without damaging the glass by overheating, when the wick nearing reaching The bottom surface of the candle is burned and the glass threatens to heat up strongly.
- the candle comprises the candle body with the wick, and a contact with the candle body area, which is also substantially incombustible and contains a flame-retardant composition and is also referred to as a flame-resistant block.
- the block has a considerable thickness or width relative to the dimensions of the candle body.
- the flame-resistant block is not only formed as in the other embodiments of a rigid bottom plate, but also has a cup shape, in which a dimensioned according to the thickness of the bottom plate peripheral wall surrounds the circumference of the candle body and a majority, anyway more than half, the height of the candle body, covered.
- US 2 240 071 A1 shows a wax light with a shell in which a paraffin body can be used with an opening.
- a wick is inserted with its short end in a clamp holder of a wick holder called base, and protrudes with the short end below the wick holder.
- the long end of the wick is passed through the opening. From the wick holder stand in the direction of the paraffin body angled prongs upwards, while looking down support projections, which rest on the bottom of the shell. After a certain period of fire, the candle body liquefies completely and substantially fills the envelope.
- WO 96/21124 A1 shows a tealight with a tealight plastic sleeve, which is held by spacers spaced from a support surface, and stand in the pin from the bottom of the tealight envelope and enclose a substantially circular area in order to prevent a wick holder, which holds a wick, to leave this central area.
- the Paraffin mass which forms the candle body, has a central opening for the passage of the wick and melts after a short burning time.
- GB 1900 03733 shows a massive candle holder, which has a cup-shaped receptacle for a candle, stand up from the three pins. Correspondingly drilled recesses in the candle are adapted to the distribution of the pins and allow a better grip of the candle by the recesses are placed on the pins.
- the candle holder itself intended for multiple use. Hierdruch especially a wobble of the candle is effectively prevented.
- EP 1 054 054 A1 shows a candle with a body made of wax or the like., Which is penetrated by a wick, which is held on the bottom side clamped in a wick holder.
- the candle with embedded wick holder is placed on a plate-like solid base part that prevents the burn-through.
- the base member has an outwardly bulging solid rim which is spaced from the periphery of the body and does not abut the body.
- Various embodiments of wick holders are spaced from a support surface of the base member via folded feet.
- the base part is designed here as a reusable part.
- U1 shows a spacer, comprising a central ring and four radially outwardly projecting webs with upwardly projecting cusp, which define a receptacle for a wick holder.
- the wick holder is kept spaced from the candle cup formed of combustible material. Since the ring is designed to be open in the region of the wick, the wick can continue to burn below the wick holder.
- US 3,330,132 A1 shows a candle holder with a protective insert, which has a central opening into which a candle is inserted.
- the central opening tapers slightly conical and can be penetrated by the candle, so that the insert has at least no burn-through barrier with respect to the candle holder represents.
- the conically tapering opening is defined by an edge that holds the circumference of the candle clamped.
- the burn-through barrier surrounds, at least in sections, the circumference of the candle body adjoining the bottom of the candle.
- this area is designed to be completely circumferential, so that in the case of a candle with a round, quadrangular or other polygonal circumference, the entire circumference of the candle is surrounded by a lower edge which is visible even when the candle is set up.
- This lower visible edge is preferably provided in a striking color or colored material, so that a clear distinction from the color of the candle is possible.
- only areas of the lower edge of the lateral surface of the candle body can be equipped with a corresponding marking, which is expediently formed integrally with the burn-through barrier or is in communication therewith.
- the burn-through barrier is formed as a foil, which covers the bottom surface of the candle at least predominantly. It is significant that especially the area of the wick, or the wicks in the case of Mehrdochtkerzen, at least insofar covered that a burning of the wick is arranged on arranged below the candle combustible material.
- a preferred burn-through avoids the risk of folding around a bending line and thus the risk that the projections provided for the better composite are displaced flat in the plane of the bottom of the burn-through barrier by the design of the projections. Rather, it remains with the design even in the case of being pushed down at least one surface which projects upwards by at least 30 ° with respect to the ground, a three-dimensional region which has advantageous properties for the connection with a candle. Particularly favorable conditions can be achieved if the vertical component of the at least one surface predominates, ie the angle of inclination is more than 45 °.
- the protrusion has a thickness changed by plastic deformation relative to the bottom of the burn-through barrier in order to counteract folding back of the protrusions.
- a correspondingly shaped punching tool can be used. If a plurality of projections provided in a burn-through, the tool can have several corresponding shapes, or it is used in the desired number of projections.
- the line in which the projection intersects the plane of the bottom of the burn-through barrier curved and preferably has a narrow radius in the manner of a crescent moon or moon segment.
- folding back of the projections is made more difficult.
- such a fold line can also form a straight line.
- the protrusions are punched out of the material of the burn-through barrier and protrude in the direction of the candle. But it is also possible to provide branches on the projections, so that in case of a change in the orientation of a projection, these branches protrude as small spines in the direction of the candle body.
- each two adjacent projections form a pair, wherein the two projections are each offset by 90 ° to each other.
- a projection of the pair has at its intersection with the bottom of the burn-through a component parallel to the direction of the peak load and thus remains substantially intact.
- a plurality of projections over the surface of the bottom of the burn-through barrier are arranged so that the connection of a candle to the burn-through barrier is as evenly as possible over the entire surface of the burn-through barrier. If the above-described pairs are formed, preferably the pairs are each arranged at equidistant angles to one another. Then the burn-through barriers can be stacked more easily. It is alternatively possible to arrange the projections or the pairs at random. Then the burn-through barriers, when stacked, are easier to separate.
- the edge is provided of aluminum, which is particularly suitable as a material for the burn-through barrier, and which can be easily deformed even with a thin-walled configuration, without being damaged.
- the burn-through barrier barely increases the weight of the candle.
- the burn-through barrier is preferably formed as an aluminum layer which is so thinly rolled that it can be easily cut to size and can also be flexibly placed on the bottom of the candle. This is particularly important if - unlike the pillar candle, which has a substantially flat bottom surface - the burn-through barrier is to be arranged on a pointed candle, the foot of which adapt to common Candle holder often tapers conically and, moreover, may have a crowned bottom surface.
- the burn-through barrier is expediently attached to the candle by means of an adhesive. This means that burn-through barriers made of material poorly adhering to wax, such as aluminum, can be connected to the candle in a simple and reliable manner. In addition, the burn-through barrier is also easy to replace again, so that when used for example in candle holders protected against burn-through, the burn-through barrier can also be removed
- a burn-through barrier receiving the candle is brought to a heated temperature of preferably 30 ° C to 70 ° C, preferably 45 ° C to 55 ° C, and then to the Candle is attached, so that the passing of the burn-through contact area of the candle body is softened and the softened material of the candle body, usually paraffin, hardens as a bonding agent and reaches an improved adhesion of the two parts.
- the heating of the burn-through barrier can take place during bending, so that the process heat of the production process is advantageously used when connecting to the candle.
- the material of the candle body serves so advantageous instead of an adhesive as a primer layer, wherein the compound by the penetrating into the candle body projections on is improved, so that even when using as such per se candle material ab dodem aluminum as the material for the burn-through barrier such a good connection is formed that can be dispensed preferably on the provision of a mandrel for skewering the candle. It will be understood that heating of the lower portion of the candle is also contemplated to accomplish the same purpose, but less satisfying the requirements for a highly automated, reproducible process.
- the burn-through barrier can also be maintained when arranged in candle holders with corresponding recesses, in particular in the case of pointed candles, since this can easily be deformed when the candle is pressed into the candle holder or where the holder is introduced into the candle Notches are made, too, notching.
- the fĂĽrbrandsperre which forms bowl-shaped due to the visible edge, then also serves when burning the candle in a candle holder in a particularly advantageous manner as a collection vessel for the fire residues, so that the candle holder when replacing the candle does not need to be cleaned, or contaminated by wax residue remains.
- the surface facing away from the candle body surface of the burn-through barrier preferably has a wax-repellent surface, so that sticking the candle provided with burn-through barrier is made difficult by means of wax.
- the burn-through device completely seals the bottom surface of the candle and has a lateral folding edge which projects beyond the adjacent to the bottom surface lateral extent of the candle body such that in a candle with a round cross section, a burn-through as a receptacle in the manner of Napfes arises.
- the receptacle is adapted to the lower shape of the candle accordingly.
- the height of the edge is always small in relation to the height of the candle, preferably less than / 10 1 . more preferably less than / 20 1 the height of the candle.
- the height of the edge is also small in proportion to the diameter of the bottom surface of a pillar candle.
- the height of the rim is approximately on the order of the diameter of the bottom surface of the candle body and preferably covers the entire conical region with a conically downwardly tapering lower foot portion of the tapered candle.
- the peripheral edge of the burn-through device is formed as a strip, which is circumferentially mounted in the adjacent to the bottom surface of the candle base portion of the candle, preferably on the strip
- Abfaltglieder for example in triangular or rectangular shape, are provided by cutting the strip which are folded down substantially vertically from the strip and are folded over on the bottom surface of the candle.
- an underlay which is at least predominantly closed for the bottom surface of the candle body is formed, which effectively prevents the wick from burning through.
- the burn-through barrier is made as a three-dimensional aluminum part, which is approximated or adapted to the contour of the candle body
- the burn-through barrier as a three-dimensional part, this is produced as a piece-like, smooth-walled part, preferably made of aluminum, but alternatively also of a non-flammable or hardly flammable plastic, and is placed on the bottom area of the candle.
- a burn-through barrier has a high rigidity and insensitivity to damage, but is thereby prone to play with the candle body and requires a correspondingly high assembly costs for connecting the two parts candle and burn-through.
- the burn-through barrier consists of a three-dimensionally carded aluminum bowl, which adjoins the contour of the foot region of the candle body is approximate and therefore associated with excess with this and can be easily connected by impressions with the candle. Furthermore, such a burn-through distance deforms easily when mounted in the candle holder or when connecting to a wreath or the like by means of wire, without this leading to the risk that the candle slides out of the holder. It is possible to crimp over the upper portion of the carded aluminum body or to provide it with a claw shape in the peripheral area into which a wire for fixing can be inserted. Furthermore, the edge may be colored as a special marking or shine by polishing itself from the rest of the body, which preferably consists of aluminum. Furthermore, the carding also allows an approach to a variety of contours, without thereby the carded foil must be specially tailored.
- the candle is permanently connected to one of the above-mentioned burn-through barriers.
- the permanent connection takes place in that a material of the candle body is heated, and after curing serves as a primer with the burn-through barrier.
- the heating of the material takes place in that the burn-through barrier is heated itself.
- a burn-through barrier 4 is provided, which consists of a circumference of the candle body 2 completely surrounding strip 4a and a bottom surface 4b
- the burn-through barrier is made of aluminum and has on its the candle body 2 facing side an adhesive on the Components of the burn-through barrier 4 is sprayed on and provides for a permanent, but releasable connection of the burn-through barrier 4 with the candle body 2
- the adhesive can also be applied only to parts of the burn-through 4 or not at all.
- the area of the strip 4a has on its outwardly facing surface a glossy consistency, which immediately conveys to a viewer that the candle is provided in the bottom area with a burn-through barrier.
- the height h of the strip 4a is small both with respect to the height and with respect to the diameter of the candle body, so that the decorative effect of the candle 1 as a whole is virtually unaffected.
- the sight of the strip 4 a of the burn-through barrier 4 which is also visible when the candle is erected, gives the viewer a feeling of security that a burn-through barrier 4 is provided.
- a preferred method for the production of a candle 1 with a wick 3 surrounded by a candle body 2 and a burn-through barrier 4, in which the burn-through barrier 4 comprises a strip 4a of aluminum material.
- the burn-through barrier 4 comprises a strip 4a of aluminum material.
- From the strip 4 a of aluminum material are laterally triangular strands 40 as Abfalt Schemee.
- the strip 4a is applied over the circumference of the candle body 2 near the bottom surface 2a, and the folding portions 40 are each bent by 90 ° to overlap together to form the bottom portion 4b.
- This method can be automated in a simple manner by the candle body 2 on a strip 4a, which may also be formed as an endless strip, and which has preferably been provided with an adhesive layer along, and initially the strip 4a on the peripheral surface of the candle body. 2 is fastened and then the folds 40 are transferred, preferably automatically by rolling along the candle 1 to a corresponding device.
- This method can be performed in a simple manner by machine.
- Fig. 3 One recognizes in Fig. 3 in that the adjacent regions of the folds 40 are separated from one another by beads 41 which effectively prevent tearing of the thin aluminum foil. It can be seen that equally well as triangular shaped folds can be selected. It can also be seen that two strips 4a with triangular folds 40 are themselves To save material, cut out of a strip that is wider than the one in the width of the strip 4a only Fig. 3 shown.
- Fig. 4 shows an alternative embodiment of a burn-through barrier 4 for a pillar candle, in which the bottom 4b and the edge 4a is made of a one-piece aluminum part, which is adapted to the dimensions of the bottom portion of the candle body 2. It is understood that instead of a smooth-surfaced configuration of the burn-through barrier, a so-called carded burn-through barrier is possible, in which the aluminum material is brought into its shape with considerable folds by carding, this method has the advantage that the burn-through barrier is easily deformed and beyond easier to adapt to difficult, not round or symmetrical geometries of a candle body.
- a candle 11 is shown, which is formed as a pointed candle and a wick 3 in a candle body 3 comprises.
- a cup-shaped or cup-shaped burn-through barrier 4 made of aluminum, which has a bottom portion 4b and a wall portion 4a.
- the base region of the pointed candle is at the same time the one that tapers conically downwards and is usually accommodated in a candle holder.
- the burn-through barrier 4 substantially covers the area of the candle 11 which is hardly perceived by a viewer, yet conveys the feeling of security when the edge 4a of the candle is recognized as a burn-through barrier. It can be seen that the inner cone of the burn-through barrier 4 corresponds to the cone of the base region of the candle 1.
- Fig. 1 to 6 are the projections 5, the in Fig. 7 to 10 have been omitted, for better illustration omitted.
- the maximum height of the projections 5 is less than half the height of the edge 4 a of the burn-through barrier 4.
- Each projection 5 consists of a semicircular, punched out of the bottom 4b and along a fold line 5c by 50 ° upwards bent portion of material, along two secant two quadrant segments 5a are folded from the material portion such that a triangular surface 5b results, the Bottom 4b opposite angle substantially 90 ° assumes.
- the angle between fold 5a and triangle 5b is approximately 90 °.
- the planes of the folds 5a and 5b of the triangle are thus inclined both with respect to the plane of the floor and with respect to the normal levels in which the insertion direction of a candle is located.
- the planes of the folds 5a and the triangle 5b form wedge surfaces in the direction of the insertion direction of a candle, so that penetration into the body of the candle is facilitated.
- the projections 5 are thus formed as a lateral surface segment of a pyramid. It is understood that, alternatively, the projections may also be formed as a lateral surface segment of other symmetrical or asymmetrical bodies such as cones, truncated cone, tetrahedron, cylinder or the like.
- a protrusion may also be formed in a spherical shape in which a semicircular recess is cut at the rectilinear peripheral portion of the recess and bent upward along the semicircular peripheral portion, thereby giving the protrusion 5 a spherical curvature to a three-dimensional formation in space above of the floor 4a.
- Each two projections 5 form a pair 50 of adjacent projections 5, which are rotated by 90 ° to each other or positioned offset. Overall, four mutually offset by 90 ° about a central region 6 of the bottom 4b pairs 50 are provided, see. Fig. 8 , In the present case, the rectilinear fold lines 5c of the two projections 5 form a right angle whose angle bisector intersect at the center of the bottom 4b.
- the center region 6 has a center which is formed flush with the bottom 4b, to which six lines 6a sunken by an amount corresponding to the thickness of the bottom 4b are directed. These serve as a positioning aid for a subsequent automated connecting step with a candle body or as an optical marking of the center point for a user.
- a tool is preferably held in the production of the projections 5 against the upwardly facing side of the bottom 4b; This is preferably also formed as a stamp for the production of the center region 6.
- the depth of the embossed line 6a corresponds approximately to the thickness of the bottom 4b.
- Fig. 10 50 ° to the plane of the bottom 4b along the fold line 5c, and the ratio of the vertical height of the projection 5 to the edge 4a of approximately one third.
- Fig. 11 the right angle between the triangular surface 5 and the fold 5a can be seen.
- the burn-through barrier 4 is heated prior to connection to a candle body and then pressed against the bottom of a candle.
- the material of the candle body is softened and the soft paraffin sticks to the bottom 4b, at the same time penetrate the projections 5 in the softened material of the candle body. It is possible, then to rotate the candle body a bit relative to the burn-through barrier 4 to allow the material of the candle body to emerge from the recesses of the burn-through barrier 4.
- the burn-through barriers having an edge visible on the periphery of the candle may also be formed as a folded, glued foil or as a three-dimensional crimped body applied to the bottom portion and the adjacent visible peripheral portion of the candle. It is further understood that the number, orientation and dimensions of the projections of the burn-through barrier can be adapted to the nature of the candle body.

Description
Die Erfindung betrifft allgemein ein Kerze mit einer Durchbrandsperre, sowie ein Verfahren zu deren Herstellung.The invention relates generally to a candle having a burn-through barrier, and to a method for the production thereof.
Kerzen mit Durchbrandsperre, die von sogenannten *Teelichtern unterschieden werden massen, sind beispielsweise aus
Es ist die Aufgabe der Erfindung, eine Kerze anzugeben, bei der die Durchbrandsperre einfach aufgebracht werden kann und dem Verbraucher in verständlicher Weise anzeigt, dass es sich um eine Kerze mit Durchbrandsperre und somit ohne Durchbrandgefahr handelt. Es ist eine weitere Aufgabe der Erfindung, ein Verfahren anzugeben, mit dem eine Kerze in wirtschaftlicher Weise mit einer Durchbrandsperre versehen werden kann.It is the object of the invention to provide a candle in which the burn-through barrier can be easily applied and the consumer in an understandable way indicates that it is a candle with burn-through and thus without burn-through. It is a further object of the invention to provide a method by which a candle can be economically provided with a burn-through barrier.
Diese Aufgabe wird erfindungsgemäß durch die in den unabhängigen Ansprüchen angegebenen Merkmale gelöst.This object is achieved by the features specified in the independent claims.
Erfindungsgemäß umgibt die Durchbrandsperre wenigstens abschnittsweise den an dem Boden der Kerze angrenzenden Umfang des Kerzenkorpus. Vorzugsweise ist dieser Bereich vollständig umlaufend ausgestaltet, so dass bei einer Kerze mit rundem, viereckigem oder anderem vieleckigen Umfang der gesamte Umfang der Kerze von einem auch bei aufgestellter Kerze sichtbaren unteren Rand umgeben ist. Dieser untere sichtbare Rand ist vorzugsweise in auffälliger Farbgebung bzw. farbigem Material vorgesehen, so dass eine klare Abgrenzung gegenüber der Farbgebung der Kerze möglich ist. Alternativ können lediglich Bereiche des unteren Randes der Mantelfläche des Kerzenkorpus mit einer entsprechenden Markierung ausgestattet sein, die zweckmäßigerweise einstückig mit der Durchbrandsperre ausgebildet ist bzw. mit dieser in Verbindung steht.According to the invention, the burn-through barrier surrounds, at least in sections, the circumference of the candle body adjoining the bottom of the candle. Preferably, this area is designed to be completely circumferential, so that in the case of a candle with a round, quadrangular or other polygonal circumference, the entire circumference of the candle is surrounded by a lower edge which is visible even when the candle is set up. This lower visible edge is preferably provided in a striking color or colored material, so that a clear distinction from the color of the candle is possible. Alternatively, only areas of the lower edge of the lateral surface of the candle body can be equipped with a corresponding marking, which is expediently formed integrally with the burn-through barrier or is in communication therewith.
Gemäß der Erfindung ist vorgesehen, dass die Durchbrandsperre als Folie ausgebildet ist, die die Bodenfläche der Kerze wenigstens überwiegend bedeckt. Hierbei ist bedeutsam, dass speziell der Bereich des Dochtes, oder der Dochte im Falle von Mehrdochtkerzen, zumindest insoweit bedeckt ist, dass ein Durchbrennen des Dochtes auf unterhalb der Kerze angeordnetes brennbares Material verhindert ist.According to the invention it is provided that the burn-through barrier is formed as a foil, which covers the bottom surface of the candle at least predominantly. It is significant that especially the area of the wick, or the wicks in the case of Mehrdochtkerzen, at least insofar covered that a burning of the wick is arranged on arranged below the candle combustible material.
Eine bevorzugte Durchbrandsperre vermeidet durch die Ausgestaltung der Vorsprünge die Gefahr eines Umklappens um eine Biegelinie und damit die Gefahr, dass die für den besseren Verbund vorgesehenen Vorsprünge flach in die Ebene des Bodens der Durchbrandsperre verdrängt werden. Vielmehr verbleibt selbst im Falle des Herabdrückens durch die Ausgestaltung mit wenigstens einer Fläche, die um wenigstens 30° gegenüber dem Boden nach oben absteht, ein dreidimensionaler Bereich, der vorteilhafte Eigenschaften für die Verbindung mit einer Kerze aufweist. Besonders günstige Verhältnisse erreicht man, wenn die vertikale Komponente der wenigstens einen Fläche überwiegt, der Neigungswinkel also mehr als 45° ausmacht.
Vorzugsweise weist der Vorsprung eine durch plastische Formänderung veränderte Dicke gegenüber dem Boden der Durchbrandsperre auf, um einem Zurückfalten der Vorsprünge entgegen zu wirken. Zur Herstellung der Vorsprünge kann ein entsprechend geformtes Stanzwerkzeug eingesetzt werden. Werden mehrere Vorsprünge in einer Durchbrandsperre vorgesehen, kann das Werkzeug mehrere entsprechende Formen aufweisen, oder es wird in der gewünschten Zahl von Vorsprüngen eingesetzt.A preferred burn-through avoids the risk of folding around a bending line and thus the risk that the projections provided for the better composite are displaced flat in the plane of the bottom of the burn-through barrier by the design of the projections. Rather, it remains with the design even in the case of being pushed down at least one surface which projects upwards by at least 30 ° with respect to the ground, a three-dimensional region which has advantageous properties for the connection with a candle. Particularly favorable conditions can be achieved if the vertical component of the at least one surface predominates, ie the angle of inclination is more than 45 °.
Preferably, the protrusion has a thickness changed by plastic deformation relative to the bottom of the burn-through barrier in order to counteract folding back of the protrusions. To produce the projections, a correspondingly shaped punching tool can be used. If a plurality of projections provided in a burn-through, the tool can have several corresponding shapes, or it is used in the desired number of projections.
Zweckmäßigerweise ist auch die Linie, in der der Vorsprung die Ebene des Bodens der Durchbrandsperre schneidet, gekrümmt ausgebildet und weist vorzugsweise einen engen Radius in der Art eines Halbmondes oder Mondsegmentes auf. Hierdurch wird ein Zurückfalten der Vorsprünge weiter erschwert. Alternativ kann eine solche Faltlinie auch eine gerade Strecke bilden.Conveniently, the line in which the projection intersects the plane of the bottom of the burn-through barrier, curved and preferably has a narrow radius in the manner of a crescent moon or moon segment. As a result, folding back of the projections is made more difficult. Alternatively, such a fold line can also form a straight line.
Zweckmäßigerweise sind die Vorsprünge aus dem Material der Durchbrandsperre herausgestanzt und stehen in Richtung auf die Kerze vor. Es ist aber auch möglich, Verzweigungen an den Vorsprüngen vorzusehen, so dass im Falle einer Änderung der Orientierung eines Vorsprungs diese Verzweigungen als kleine Dorne in Richtung auf den Kerzenkorpus vorstehen.Conveniently, the protrusions are punched out of the material of the burn-through barrier and protrude in the direction of the candle. But it is also possible to provide branches on the projections, so that in case of a change in the orientation of a projection, these branches protrude as small spines in the direction of the candle body.
Vorzugsweise bilden jeweils zwei benachbarte Vorsprünge ein Paar, wobei die beiden Vorsprünge jeweils um 90° zueinander versetzt sind. Hierdurch ist auch bei einer Belastungsspitze in eine Richtung, beispielsweise durch unsachgemäßes Einsetzen der Kerze, sichergestellt, dass ein Vorsprung des Paares an seiner Schnittlinie mit dem Boden der Durchbrandsperre eine Komponente parallel zu der Richtung der Belastungsspitze aufweist und damit im Wesentlichen unversehrt bleibt.Preferably, each two adjacent projections form a pair, wherein the two projections are each offset by 90 ° to each other. As a result, it is ensured even at a peak load in one direction, for example by improper insertion of the candle, that a projection of the pair has at its intersection with the bottom of the burn-through a component parallel to the direction of the peak load and thus remains substantially intact.
Zweckmäßigerweise sind mehrere Vorsprünge über die Fläche des Bodens der Durchbrandsperre angeordnet, so dass die Anbindung einer Kerze an die Durchbrandsperre möglichst gleichmäßig über die gesamte Fläche der Durchbrandsperre erfolgt. Sind die vorstehend erläuterten Paare gebildet, so sind vorzugsweise die Paare jeweils in äquidistanten Winkeln zueinander angeordnet. Dann lassen sich die Durchbrandsperren leichter stapeln. Es Ist alternativ möglich, die Vorsprünge oder die Paare zufällig anzuordnen. Dann lassen sich die Durchbrandsperren, wenn sie gestapelt sind, leichter trennen.Conveniently, a plurality of projections over the surface of the bottom of the burn-through barrier are arranged so that the connection of a candle to the burn-through barrier is as evenly as possible over the entire surface of the burn-through barrier. If the above-described pairs are formed, preferably the pairs are each arranged at equidistant angles to one another. Then the burn-through barriers can be stacked more easily. It is alternatively possible to arrange the projections or the pairs at random. Then the burn-through barriers, when stacked, are easier to separate.
Vorzugsweise wird der Rand aus Aluminium vorgesehen, welches als Material für die Durchbrandsperre besonders geeignet ist, und welches auch bei dünnwandiger Ausgestaltung leicht verformt werden kann, ohne beschädigt zu werden. Damit erhöht die Durchbrandsperre das Gewicht der Kerze kaum. Die Durchbrandsperre ist vorzugsweise als eine Aluminiumschicht gebildet, die derart dünn ausgewalzt ist, dass sie einfach zugeschnitten werden kann und auch flexibel an den Boden der Kerze angeordnet werden kann. Dies ist besonders dann bedeutsam, wenn - anders als bei der Stumpenkerze, die eine im Wesentlichen flache Bodenfläche aufweist - die Durchbrandsperre an einer Spitzkerze angeordnet werden soll, deren Fuß sich zur Anpassung an gängige Kerzenhalter häufig konisch verjüngt und darüber hinaus eine Bodenfläche mit Balligkeit aufweisen kann.Preferably, the edge is provided of aluminum, which is particularly suitable as a material for the burn-through barrier, and which can be easily deformed even with a thin-walled configuration, without being damaged. Thus, the burn-through barrier barely increases the weight of the candle. The burn-through barrier is preferably formed as an aluminum layer which is so thinly rolled that it can be easily cut to size and can also be flexibly placed on the bottom of the candle. This is particularly important if - unlike the pillar candle, which has a substantially flat bottom surface - the burn-through barrier is to be arranged on a pointed candle, the foot of which adapt to common Candle holder often tapers conically and, moreover, may have a crowned bottom surface.
Die Durchbrandsperre ist zweckmäßigerweise mittels eines Klebers an der Kerze befestigt Damit lassen sich auch Durchbrandsperren aus schlecht an Wachs anhaftendem Material wie Aluminium in einfacher und zuverlässiger Weise mit der Kerze verbinden. Darüber hinaus ist die Durchbrandsperre auch einfach wieder abzulösen, so dass beim Einsatz beispielsweise in gegen Durchbrand geschützten Kerzenhaltern die Durchbrandsperre auch entfembar istThe burn-through barrier is expediently attached to the candle by means of an adhesive. This means that burn-through barriers made of material poorly adhering to wax, such as aluminum, can be connected to the candle in a simple and reliable manner. In addition, the burn-through barrier is also easy to replace again, so that when used for example in candle holders protected against burn-through, the burn-through barrier can also be removed
Gemäß einem Verfahren zur Herstellung einer mit einer Kerze verbundenen Durchbrandsperre ist jedoch vorgesehen, dass eine die Kerze aufnehmende Durchbrandsperre auf eine erwärmte Temperatur von zweckmäßigerweise 30°C bis 70°C, vorzugsweise 45°C bis 55°C, gebracht wird und dann an die Kerze angesetzt wird, so dass der mit der Durchbrandsperre in Kontakt tretende Bereich des Kerzenkorpus erweicht wird und das erweichte Material des Kerzenkorpus, meist Paraffin, als Haftvermittler aushärtet und eine verbesserte Anhaftung der beiden Teile erreicht. Durch das Erweichen des Kerzenkorpus wird auch der Eindringwiderstand für die Vorsprünge der Durchbrandsperre reduziert und die Gefahr des unbeabsichtigten Abflachens noch weiter reduziert. Vorteilhaft kann die Erwärmung der Durchbrandsperre beim Biegen erfolgen, so dass die Prozesswärme des Herstellungsverfahrens beim Verbinden mit der Kerze vorteilhaft genutzt wird. Das Material des Kerzenkorpus dient so vorteilhaft statt eines Klebers als Haftvermittlungsschicht, wobei die Verbindung durch die in den Kerzenkorpus eindringenden Vorsprünge weiter verbessert wird, so dass auch bei Verwendung von an sich Kerzenmaterial abweisendem Aluminium als Werkstoff für die Durchbrandsperre eine derart gute Verbindung entsteht, dass vorzugsweise auf das Vorsehen eines Dorns zum Aufspießen der Kerze verzichtet werden kann. Es versteht sich, dass auch eine Erwärmung des unteren Bereichs der Kerze zum Erreichen desselben Zwecks in Betracht kommt, was aber den Anforderungen an einen hoch automatisierten reproduzierbaren Prozess weniger gerecht wird.
Besonders vorteilhaft kann jedoch die Durchbrandsperre auch beim Anordnen in Kerzenhaltern mit entsprechenden Vertiefungen, insbesondere im Fall von Spitzkerzen, beibehalten werden, da diese sich mit dem Einpressen der Kerze in den Kerzenhalter leicht deformieren lässt bzw. dort, wo die Halterung über in die Kerze eingebrachte Kerben erfolgt, auch einkerben lässt. Die Durchbrandsperre, die sich aufgrund des sichtbaren Randes napfförmig ausbildet, dient dann auch beim Abbrand der Kerze in einem Kerzenhalter in besonders vorteilhafter Weise als Sammelgefäß für die Brandrückstände, so dass der Kerzenhalter beim Austausch der Kerze nicht mehr gereinigt werden muss, oder durch Wachsrückstände verunreinigt bleibt.According to a method for producing a burn-through barrier connected to a candle, however, it is provided that a burn-through barrier receiving the candle is brought to a heated temperature of preferably 30 ° C to 70 ° C, preferably 45 ° C to 55 ° C, and then to the Candle is attached, so that the passing of the burn-through contact area of the candle body is softened and the softened material of the candle body, usually paraffin, hardens as a bonding agent and reaches an improved adhesion of the two parts. By softening the candle body and the penetration resistance for the projections of the burn-through barrier is reduced and the risk of unintentional flattening even further reduced. Advantageously, the heating of the burn-through barrier can take place during bending, so that the process heat of the production process is advantageously used when connecting to the candle. The material of the candle body serves so advantageous instead of an adhesive as a primer layer, wherein the compound by the penetrating into the candle body projections on is improved, so that even when using as such per se candle material abweisendem aluminum as the material for the burn-through barrier such a good connection is formed that can be dispensed preferably on the provision of a mandrel for skewering the candle. It will be understood that heating of the lower portion of the candle is also contemplated to accomplish the same purpose, but less satisfying the requirements for a highly automated, reproducible process.
Particularly advantageously, however, the burn-through barrier can also be maintained when arranged in candle holders with corresponding recesses, in particular in the case of pointed candles, since this can easily be deformed when the candle is pressed into the candle holder or where the holder is introduced into the candle Notches are made, too, notching. The Durchbrandsperre, which forms bowl-shaped due to the visible edge, then also serves when burning the candle in a candle holder in a particularly advantageous manner as a collection vessel for the fire residues, so that the candle holder when replacing the candle does not need to be cleaned, or contaminated by wax residue remains.
Die dem Kerzenkorpus abgekehrte Oberfläche der Durchbrandsperre weist vorzugsweise eine wachsabweisende Oberfläche auf, so dass ein Aufkleben der mit Durchbrandsperre versehenen Kerze mittels Wachs erschwert ist. Es ist aber möglich, durch einen Haftvermittler auf dieser Oberfläche eine bessere Anhaftung an Wachs zu ermöglichen.The surface facing away from the candle body surface of the burn-through barrier preferably has a wax-repellent surface, so that sticking the candle provided with burn-through barrier is made difficult by means of wax. However, it is possible to allow a better adhesion to wax by a primer on this surface.
Vorzugsweise ist vorgesehen, dass die Durchbrandeinrichtung die Bodenfläche der Kerze vollständig versiegelt und eine seitliche Abfaltung als Rand aufweist, die über den an die Bodenfläche angrenzenden seitlichen Umfang des Kerzenkorpus übersteht derart, dass bei einer Kerze mit rundem Querschnitt eine Durchbrandsperre als Aufnahme in der Art eines Napfes entsteht. Bei anderen Kerzenquerschnitten ist die Aufnahme entsprechend an die untere Form der Kerze angepasst. Die Höhe des Randes ist aber stets klein im Verhältnis zur Höhe der Kerze, vorzugsweise weniger als
Gemäß einer Ausgestaltung der Erfindung ist der umlaufende Rand der Durchbrandeinrichtung als Streifen ausgebildet, der im an die Bodenfläche der Kerze angrenzenden Fußbereich der Kerze umlaufend angebracht ist, wobei vorzugsweise an dem Streifen Abfaltglieder, beispielsweise in dreieckiger oder rechteckiger Form, durch Einschneiden des Streifens vorgesehen sind, die von dem Streifen im Wesentlichen senkrecht abgefaltet werden und auf die Bodenfläche der Kerze umgelegt werden. Durch das neben- oder übereinander Ablegen der abgefalteten Bereiche wird eine wenigstens überwiegend geschlossene Unterlage für die Bodenfläche des Kerzenkorpus gebildet, die ein Durchbrennen des Dochtes wirksam verhindert.According to one embodiment of the invention, the peripheral edge of the burn-through device is formed as a strip, which is circumferentially mounted in the adjacent to the bottom surface of the candle base portion of the candle, preferably on the strip Abfaltglieder, for example in triangular or rectangular shape, are provided by cutting the strip which are folded down substantially vertically from the strip and are folded over on the bottom surface of the candle. By depositing the folded regions next to or above one another, an underlay which is at least predominantly closed for the bottom surface of the candle body is formed, which effectively prevents the wick from burning through.
Gemäß einer Ausgestaltung der Erfindung ist vorgesehen, dass die Durchbrandsperre als dreidimensionales Aluminiumteil hergestellt ist, welches an die Kontur des Kerzenkorpus angenähert oder angepasst istAccording to one embodiment of the invention it is provided that the burn-through barrier is made as a three-dimensional aluminum part, which is approximated or adapted to the contour of the candle body
Gemäß einer ersten Ausführungsform der Durchbrandsperre als dreidimensionales Teil ist diese als elhstücklges, glattwandiges Teil, vorzugsweise aus Aluminium, alternativ aber auch aus einem nicht brennbaren oder schwer entzündlichen Kunststoff, hergestellt, und wird auf den Bodenbereich der Kerze aufgesetzt. Eine solche Durchbrandsperre weist eine hohe Steifigkeit und Unempfindlichkeit gegenüber Beschädigungen auf, ist hierdurch aber anfällig für ein Spiel mit dem Kerzenkorpus und erfordert einen entsprechend hohen Montageaufwand zum Verbinden der beiden Teile Kerze und Durchbrandsperre.According to a first embodiment of the burn-through barrier as a three-dimensional part, this is produced as a piece-like, smooth-walled part, preferably made of aluminum, but alternatively also of a non-flammable or hardly flammable plastic, and is placed on the bottom area of the candle. Such a burn-through barrier has a high rigidity and insensitivity to damage, but is thereby prone to play with the candle body and requires a correspondingly high assembly costs for connecting the two parts candle and burn-through.
Gemäß einer zweiten Ausführungsform der Durchbrandsperre als dreidimensionales Teil besteht die Durchbrandsperre aus einem dreidimensional gekrempelten Aluminiumnapf, der an die Kontur des Fußbereichs des Kerzenkorpus angenähert ist und daher mit Übermaß mit diesem verbunden und durch Eindrücken leicht mit der Kerze verbunden werden kann. Weiterhin deformiert sich eine solche Durchbrandsperne einfach beim Anbringen in den Kerzenhalter oder beim Verbinden mit einem Kranz oder dergleichen mittels Draht, ohne dass hierdurch die Gefahr besteht, dass die Kerze aus dem Halter herausgleitet. Es ist möglich, den oberen Bereich des gekrempelten Aluminiumkörpers umzubördeln oder mit einer Klauengestalt im Randbereich vorzusehen, in die ein Draht zum Fixieren eingebracht werden kann. Ferner kann der Rand als besondere Kennzeichnung eingefarbt sein oder durch Polieren sich glanzmäßig von dem übrigen Körper, der vorzugsweise aus Aluminium besteht, abheben. Ferner ermöglicht das Krempeln auch eine Annäherung an verschiedenste Konturen, ohne dass hierdurch die gekrempelte Folie besonders zugeschnitten werden muss.According to a second embodiment of the burn-through barrier as a three-dimensional part, the burn-through barrier consists of a three-dimensionally carded aluminum bowl, which adjoins the contour of the foot region of the candle body is approximate and therefore associated with excess with this and can be easily connected by impressions with the candle. Furthermore, such a burn-through distance deforms easily when mounted in the candle holder or when connecting to a wreath or the like by means of wire, without this leading to the risk that the candle slides out of the holder. It is possible to crimp over the upper portion of the carded aluminum body or to provide it with a claw shape in the peripheral area into which a wire for fixing can be inserted. Furthermore, the edge may be colored as a special marking or shine by polishing itself from the rest of the body, which preferably consists of aluminum. Furthermore, the carding also allows an approach to a variety of contours, without thereby the carded foil must be specially tailored.
Erfindungsgemäß ist die Kerze bleibend mit einer der vorstehend angeführten Durchbrandsperren verbunden. Zweckmäßigerweise erfolgt die bleibende Verbindung dadurch, dass ein Material des Kerzenkorpus erwärmt wird, und nach dem Aushärten als Haftverrmittler mit der Durchbrandsperre dient. Zweckmäßig erfolgt die Erwärmung des Materials dadurch, dass die Durchbrandsperre selbst erwärmt wird.According to the invention, the candle is permanently connected to one of the above-mentioned burn-through barriers. Conveniently, the permanent connection takes place in that a material of the candle body is heated, and after curing serves as a primer with the burn-through barrier. Suitably, the heating of the material takes place in that the burn-through barrier is heated itself.

Die Höhe h des Streifens 4a ist sowohl gegenüber der Höhe als auch gegenüber dem Durchmesser des Kerzenkorpus klein, so dass die dekorative Wirkung der Kerze 1 insgesamt so gut wie gar nicht beeinträchtigt wird. Zugleich vermittelt der Anblick des auch bei aufgestellter Kerze sichtbaren Streifens 4a der Durchbrandsperre 4 dem Betrachter ein Sicherheitsgefühl, dass eine Durchbrandsperre 4 vorgesehen ist.The area of the

Jeder Vorsprung 5 besteht aus einem halbrunden, aus dem Boden 4b ausgestanzten und entlang einer Faltlinie 5c um 50° nach oben abgebogenen Materialabschnitt, wobei entlang zweier Sekanten zwei Viertelkreissegmente 5a derart von dem Materialabschnitt abgefaltet sind, dass sich eine dreieckige Fläche 5b ergibt, deren dem Boden 4b gegenüberliegender Winkel im Wesentlichen 90° annimmt. Der Winkel zwischen Abfaltung 5a und Dreieck 5b beträgt dabei ca. 90°. Die Ebenen der Abfaltungen 5a und des Dreiecks 5b sind also sowohl gegenüber der Ebene des Bodens als auch gegenüber den hierzu normalen Ebenen, in denen die Einsetzrichtung einer Kerze liegt, geneigt. Überdies bilden die Ebenen der Abfaltungen 5a und des Dreiecks 5b Keilflächen in Richtung auf die Einsetzrichtung einer Kerze, so dass ein Eindringen in den Korpus der Kerze erleichtert ist. Durch diese einfache Maßnahme erreicht man überdies wirkungsvoll eine Aussteifung der Vorsprünge 5 und unterbindet damit ein Flachpressen der Vorsprünge durch eine Kerze. Die Vorsprünge 5 sind somit ausgebildet wie ein Mantelflächensegment einer Pyramide.

Die Erfindung ist vorstehend anhand von zwei Ausführungsbeispielen erläutert worden, die Kerzen mit Durchbrandsperren zeigen, die eine relativ glatte Struktur aufweisen. Es versteht sich, dass die Durchbrandsperren, die einen am Umfang der Kerze sichtbaren Rand aufweisen, auch als gefaltete, aufgeklebte Folie oder als gekrempelter dreidimensionaler Körper ausgebildet sein können, die auf den Bodenbereich und den angrenzenden sichtbaren Umfangsbereich der Kerze aufgebracht werden. Es versteht sich ferner, dass die Anzahl, Orientierung und Abmessungen der Vorsprünge der Durchbrandsperre an die Beschaffenheit des Kerzenkorpus angepasst werden können.The invention has been explained above with reference to two embodiments showing candles with burn-through barriers, which have a relatively smooth structure. It should be understood that the burn-through barriers having an edge visible on the periphery of the candle may also be formed as a folded, glued foil or as a three-dimensional crimped body applied to the bottom portion and the adjacent visible peripheral portion of the candle. It is further understood that the number, orientation and dimensions of the projections of the burn-through barrier can be adapted to the nature of the candle body.
