Description

grave light

The invention relates to a grave light made of wood or wood material.

According to the state of the art, grave lights are in the form of plastic cups which are closed with a metal lid.

DE102016101567A1 discloses a candle container which is formed from several container parts which can be assembled. The candle container is made up of several separate container parts. As a result, a separation into a reusable part of the container on the one hand and a part of the container to be disposed of as waste on the other hand can be achieved. At the same time, this ensures easy handling and significantly reduces the amount of waste produced compared to the prior art. The greater the proportion of recyclable container parts, the greater the waste spam. Simple handling can be achieved by simply replacing the container parts. DE102016101567A1 mentions all materials that can be suitable for the container base or the candle shell. In addition to many other materials, wood is also mentioned in this context, although it is not specified whether the container bottom or the container wall can be made of wood, or how and how this is suitable for use with candles. A grave light is shown in FIG. 24 of DE102016101567A1, for which it is only disclosed that this has a candle cover that can be dismantled and a cover. Since DE102016101567A1 does not reveal any further details about the grave light, it can be assumed that its further features are designed according to the above-mentioned prior art, or would be implemented by a person skilled in the art in this way, i.e. with a plastic cover.

WO2020086005A1 describes a candle shell with a base element and lid made of cast fiber and with openings in the shell of the cup, with the shell being inserted into the base element.

The ES1225294U states that a candle should have a cover made of biodegradable material, in particular paper.

The CN105841123A shows a candlestick cut/milled from a solid piece of wood.

GBl 98295 A shows a night light which is placed in a paper or wood fiber tray and which can be burned off in water or otherwise.

The JPS48106677U shows a candle shell made of a transparent or translucent plastic with a base made of metal.

The object on which the invention is based is to provide a grave light, in particular a disposable grave light, which has a lower proportion of plastic than conventional grave lights.

To solve the problem, a grave light according to claim 1 is proposed, such a grave light in combination with a cover and a method for producing the grave light. In particular, a grave light comprising a container and a combustible mass with a wick accommodated therein is proposed, this having a container wall made of wood veneer or bamboo veneer, the container wall being provided with a flame retardant and being closed on one side with a base element.

The container wall is formed from a continuous sheet of wood veneer or bamboo veneer. This means that the container wall has no openings or holes. Apertures or holes are disadvantageous in a wood veneer or bamboo veneer because they weaken the structure and encourage tearing of the veneer along the grain.

The continuous expanded wood veneer is rolled up to form a hollow cylinder and is connected to itself in the overlapping area, in particular glued, and is closed on one side with a floor element.

In a first embodiment variant, the container wall is filled with a fuel mass.

In a second embodiment variant, a prefabricated fuel mass with a wick is introduced into the container wall as a solid body, with the solid body being designed slightly smaller than the inner diameter of the container wall. The resulting annular gap between the container wall and the fuel mass present concentrically in this is preferably less than 2 mm.

The grave light according to the invention has a container wall made of wood veneer or bamboo veneer, with the container wall being provided with a flame retardant.

The flame retardant is preferably a flame retardant for absorbent material. Suitable flame retardants for wood are known and available on the market. A commercially available flame retardant is preferably used which, when used on wood, leads to at least B2 protection according to DIN 4102-1, particularly preferably B1 protection.

The flame retardant can be applied with or as a paint.

The flame retardant can be applied as an impregnation.

The flame retardant can be applied, for example, by spraying or dipping.

The flame retardant can be applied to the finished container wall or to the material from which the container wall is formed.

The flame retardant can be applied by lamination as or in a film. The flame retardant can be attached to the wood or bamboo material by laminating or gluing a film. The flame retardant can be in the form of a coating or can be contained in the material of a coating.

The wood can be in the form of veneer sheet, which is obtained in a known manner (eg peeling or sawing) from a tree trunk or from pressed bamboo blocks. The veneer sheet can be in the form of an uncoated real wood veneer. The foil sheet can be provided with a plastic foil on one or both sides. The wood veneer or the bamboo veneer preferably has a grain which particularly preferably runs in the circumferential direction of the container wall. However, the grain can also run in the longitudinal direction of the container wall or transversely to it.

A film on the later inside of the container wall can be made of a non-flammable or hardly flammable material and thus represent the flame retardant.

The veneer can be bamboo veneer, for example, which is cut from pressed bamboo blocks.

Within the meaning of the present invention, bamboo falls under the term wood, even if bamboo is a woody grass.

The container wall is preferably firmly connected to a base element. In particular, the container wall is glued to a base element, in particular glued.

The base element is preferably inserted into the inside of the container wall and connected, preferably glued, in particular glued, to the inside of the container wall on its outer circumference.

The container wall is preferably cylindrical. Preferably, the bottom element is a circular disk.

The floor element is preferably made of wood or wood material.

The base element and the container wall are preferably made of the same wood or of bamboo.

The base element is preferably present with a greater material thickness than the container wall.

The material thickness of the container wall is preferably in the range from 0.2 to 2 mm, in particular in the range from 0.3 to 1 mm, particularly preferably in the range from 0.3 mm to 0.6 mm.

The material thickness of the floor element is preferably in the range from 0.3 mm to 1 cm, in particular in the range from 1 to 5 mm, particularly preferably in the range from 1 mm to 2 mm. The base element is preferably at least 0.5 mm thick, in particular at least 1 mm thick. The floor element is preferably made of wood, derived timber product or bamboo veneer, but less preferably it can also be made of another material, such as metal, plastic or paper or cardboard material, or can include such a material.

The container wall is preferably translucent.

Since the edges of a thin sheet of wood or bamboo are sensitive, one embodiment variant can provide for the upper and/or lower edge of the container wall to be reinforced, for example by a coating, a coating, a film, a ring-shaped element or a sleeve. An additional band or an additional layer of wood or wood-based material can also be attached to the inside or outside of the container wall to reinforce the edge area. The container wall preferably has a reinforcement in that area of the container wall which is accommodated in an attached lid and is present in an area directly below without this reinforcement.

The flame retardant can be applied to the material of the container wall, for example as a coating or as an impregnation. The flame retardant is applied at least on one side to what will later be the inside of the container wall.

Preferably, the container wall is formed from a sheet of wood veneer or bamboo veneer which is rolled up. The rolling up takes place in the circumferential direction and in a straight line, resulting in a hollow body that is open on both sides and has an overlapping region that runs straight in the longitudinal direction. In the overlapping area of the sheet with itself, a connection of the two overlapping areas of the sheet takes place, so that the container wall results, in particular a cylindrical container wall. For production, the sheet can be wound around a shaped element, in particular a mandrel.

The overlapping areas are preferably connected by gluing. The connection can, less preferably, also be effected by additional elements such as clamps or adhesive strips, or by pressing.

For example, a wood glue, solvent-based adhesive, dispersion adhesive, or hot-melt adhesive or a combination of adhesives can be used as the adhesive.

Preferably, the areas overlap to an extent of 3mm to 25mm.

To produce the container, a sheet of wood or wood material or bamboo fumier is preferably first rolled up and connected to itself in the overlapping area; then the floor element is connected to the resulting hollow body, which is open on both sides, in order to close it off on one side. After that, either a wick is placed in the hollow body, which is closed on one side, and the hollow body is then filled with a fuel mass, or a finished element comprising fuel mass and wick is inserted into the hollow body, which is open on one side.

Before being rolled up, the sheet is preferably moistened, more preferably with a liquid flame retardant. By moistening or by the liquid flame retardant, the sheet becomes more flexible or elastic and damage when it is rolled up is avoided.

In the first variant, the wick can already be attached to the base element.

In the second variant, the sheet of wood or wood-based material can also be wound around the fuel mass, so that this serves as a winding mandrel. The base element can be placed on the underside of the burning mass before winding, or only after winding.

The container wall preferably has a constant outer circumference and/or a constant inner circumference over the entire height of the container. At the top, a grave light cover is preferably placed on the upper edge of the container wall. The grave light cover preferably has a shoulder or a bulge on the inside, which limits the height of the grave light cover that can be pushed on. The grave light cover has openings in its cover wall. As is usual in the prior art, the grave light cover is preferably made of metal.

The container wall and/or the base element can be provided with a water-repellent or water-resistant layer, in particular on the outside, for example with a coating or an additional layer, in particular in the form of a film. The container wall and/or the base element can be provided with printing and/or a label. The container wall and/or the base element can advantageously be inscribed by means of a laser. This can be done both black (or by darkening the wood material) and colored. An inscription can also be achieved with other engraving techniques (material removal, branding). Labeling can also be done with stamps or brands.

The grave light can also include a cover of a grave light, which cover is intended to be placed on top of a container wall of the grave light, the cover having a lower section of its wall with a larger inner diameter than in a region of its wall adjoining it. The lower section of the lid can preferably be folded inwards and upwards at its lower end. The lower, larger inner diameter of the cover wall is preferably greater than or equal to the outer diameter of the container wall. The smaller internal diameter of the top wall adjoining this is preferably smaller than or equal to the internal diameter of the container wall.

In the case of the lid, it is preferred that the material of the lid runs upwards from the lower edge inside the lower section. At the top of this inner portion there may be a bead of the material of the lid.

In the case of the lid, it is preferred that the material of the lid runs upwards from the lower edge on the inside in the lower section up to the transition between the lower section and the area adjoining it.

The lid is preferably placed on the container wall, which is formed from a sheet of material, in particular wood or derived timber product, which is rolled up and connected to itself in the overlapping area.

The lid is preferably slipped onto the upper edge of the rolled-up sheet so that the edge of the sheet rests either on the bead or on the transition between the lower section and the area of the lid adjoining it.

The lid also has, as is known from the prior art, a closed roof and openings in its peripheral wall, in the region of the lid adjoining said above.

However, the grave light according to the invention, comprising container wall and base element, can also be used without a cover or with covers of a different design. The invention is exemplified by drawings:

Fig. 1: illustrates the invention using an exemplary grave light cup according to the invention with a lid in an exploded view.

Fig. 2 illustrates the invention using an exemplary grave light cup according to the invention with a lid and burning mass.

Fig. 3: shows an example of a cover that is suitable for the grave light in question.

Fig. 4: illustrates another cover suitable for the present grave light by way of example.

As illustrated in FIG. 1, the container wall 1 in the preferred embodiment is made of a sheet of wood or wood-based material. Bamboo lining is formed, which is rolled up to form a hollow cylinder and is connected to itself in the overlapping area 2, in particular glued.

With the exception of the overlapping area 2, the container wall 1 is preferably in one layer. A multiple winding of the sheet or a sheet that is already present in several layers are conceivable, however, in order to achieve a multi-layer container wall.

The sheet of wood or engineered wood includes a flame retardant. Less preferably, the finished container wall 1 can be provided with a flame retardant.

In the preferred embodiment variant, the base element 3 is a circular disk. The material of the base element 3 can be selected differently than the material of the container wall 1, but it is preferably the same material.

The bottom element 3 is preferably inserted inside the container wall 1 and connected to it in the edge area, in particular glued. The underside of the base element 3 can lie flush with the lower edge of the container wall 1, or can be offset inwards into this.

In a known manner, the cover 4 has openings and a closed roof in order to protect the flame from the weather. However, the cup including container wall 1 and base element 3 can also be used without lid 4, or can be offered for sale. For example, for use in a weather-protected location.

The lid 4 has a shoulder 5 on the inside to limit the height of attachment. This can be done by forming the material of the lid 4 outwards in the lower area, so that the lower area of the lid 4 has a larger inner diameter than the outer diameter of the container wall 1. Less preferably, the shoulder 5 can be formed by forming from the inside the top wall protrusions protrude inwards, for example by the top wall being dented inwards.

Less preferably, the lid wall can also remain in the attached position by friction or a press fit on the container wall 1, so that the user decides how far the lid 4 is attached. FIG. 2 illustrates the assembled grave light comprising the parts already described in FIG. The fuel mass 6 is preferably introduced as a casting compound, so that it completely fills the container wall 1 up to the filling level, that is to say it bears or adheres to it on all sides. In a less preferred variant, the fuel mass 6 is prefabricated with a wick and introduced into the container wall 1 as a solid. In order to be able to reliably insert the solid body into the container wall 1, it must be made slightly smaller than the inner dimensions of the container wall 1. Any resulting annular gap between the container wall 1 and a fuel mass 6 concentrically present in it is preferably less than 2 mm, particularly preferred less than 1 mm.

When the fuel mass 6 has burned down, the container including the container wall 1 and the base element 3 is disposed of as a unit as intended. The grave light according to the invention is therefore preferably a disposable product.

Fig. 3 illustrates a lid 4 suitable for the present invention.

The jacket or the wall of the cover 4 is designed with a larger inner diameter in the lower section 7 than in the region 8 of the jacket or the wall adjoining it. The material of the lid 4 is folded inwards to form a fold at the lower edge 9 of the lid 4, so that the lower edge area of the lid 4 is double-walled.

The inner area 10 of the material of the cover 4 preferably runs up to that area 8 with a smaller inner diameter.

Preferably, the upper end of the inner portion 10 is folded or curled inward to create a ridge 11 . The bead 11 is preferably folded or rolled inwards, downwards.

A bulge is known from conventional covers of grave lights, but this is present at the lower edge of the cover and is rolled up outwards.

The lid 4 can rest with the bead 11 on the container wall 1, or with the shoulder 5, which is located in the transition between the lower section 7 and the upper area 8, depending on whether there is a bead 11 and how strong this and the shoulder 5 are pronounced.

If there is a gap between the bead 11 and the inner portion 10, the upper edge of the container wall 1 can be clamped into this gap.

Instead of the bead 11, the inner portion 10 may be bent inwardly at its upper end to protrude inwardly of the lid 4, as illustrated in FIG. In this case, the lid 4 can be formed with a unitary outer shell portion. At the end of the area 12 running inwards, a bead or an area running downwards can again be provided in one embodiment variant. The area 12 running inwards can run inwards at least in sections at an angle of 90° from the cover wall, around a straight line shoulder 5 to form. In one variant, the region 12 running inwards can be designed to be inclined upwards at least in sections. It is advantageous here if the lower edge of the openings in the wall of the cover 4 are below the inner edge of the area 12 running inward, so that any liquid that penetrates is drained to the outside. The shape of the openings is illustrated as round, but these can be any shape. The cover 4 can be formed from one piece, or from several, in particular two parts - be put together - an outer wall and an inner wall. The inner wall comprises the inner area 10 and preferably the inwardly extending area 12.
