Definitions

  • the invention concerns a plastic tealight cup comprising a bottom and an outer wall, wherein the bottom comprises an inclined part, characterised in that the inclined part runs from the outer wall and that the inclined part has an incline of > 1°.
  • the radial length of the inclined part is preferably at least 20% of the radius of the tealight cup.
  • Tealight cups of this kind have a more complete use of fuel, such as paraffin.
  • the invention also concerns tealights with tealight cups of this kind and methods for the production thereof.
  • Tealights consist of a tealight cup fitted with a wick holder with wick, and fuel, such as paraffin or wax. They typically measure approximately 38 mm in diameter, and the height depends on the desired burning time and the corresponding amount of fuel required. The burning time is indicated at the sale of tealights. It is typically between 3 and 8 hours. Most tealight cups are made of aluminium, although plastic tealight cups also exist.
  • a disadvantage of tealights according to the state of the art is that an unused residue of fuel always remains in the cup. Although the residual weight of fuel per cup seems relatively low, this causes an annual loss of many tons of fuel given the considerable volume of production of tealights.
  • the underlying goal of the current invention is therefore to give tealights a more complete use of fuel.
  • DE19548958 attempts to obtain a more complete combustion by using grooves that are lower than the bottom of the tealight cup.
  • WO2010/064941 also offers adjusted tealight cups with sunken, inclined grooves.
  • the tealight cups of both references have the disadvantage that a considerable amount of fuel still remains, particularly along the outer edge of the bottom.
  • the inventor has in fact established that the greatest residual amount of fuel is located in the interface area between the bottom and the outer wall.
  • the cups according to the current invention produce a lower residual amount of fuel, including in the interface area of the bottom and the outer wall, i.e. the area where the greatest loss occurs.
  • the inventor has discovered that a much more complete use of fuel can be obtained by giving the bottom of the cup an incline, with the incline running up to the outer wall.
  • the current invention therefore envisages a tealight cup according to claim 1, comprising a bottom and an outer wall, wherein the bottom comprises an inclined part, characterised in that the inclined part runs from the outer wall and that the inclined part has an incline of > 1°.
  • the radial length of the inclined part is at least 20% of the radius of the tealight cup.
  • the inclined part comprises at least a first inclined plane that is connected to the outer wall and preferably has an incline of between 15° and 45°.
  • the inclined part furthermore comprises a second inclined plane.
  • the second inclined plane has an incline that is smaller than the incline of the first inclined plane.
  • the first inclined plane is connected to the second inclined plane.
  • the second inclined plane as described herein preferably has an incline of between 1° and 35°, in particular between 1° and 25°, more particularly between 1° and 15°.
  • the second inclined plane has an incline of at least 10°.
  • the second inclined plane has an incline of 10° to 20°, in particular of approximately 12° to approximately 15°.
  • the inclined part preferably has an incline of at least 3°, more particularly of at least 5°.
  • the first inclined plane meets the outer wall at 40% to 55% of the height of the wall and runs to a height of 1% to 10% of the height of the outer wall. More particularly, the height difference of the first inclined part is 20% to 40% of the height of the outer wall.
  • the radius of the first inclined part is 25% to 45% of the radius of the tealight cup.
  • the tealight cup is made in such a way that when it is placed upon an external surface, a (hollow) space is created between the outer wall, the bottom, and the external surface.
  • the outer wall at least runs down to, or below, the last point of the bottom. It has been observed that an even better runoff of the paraffin can be achieved in this way.
  • the space functions as an insulating space. The air in the space will partially warm up, but dissipation of heat to the ambient air is avoided.
  • the hollow space preferably continues between the first inclined plane and the outer wall.
  • the inclined part furthermore comprises ribs that run radially in the direction of the centre of the bottom.
  • the bottom of the tealight cup normally comprises a central surface that supports the wick holder.
  • the central surface comprises radially oriented grooves.
  • the central surface is situated 0.1 to 1 mm lower than the lowest part of the inclined part.
  • Tealight cups are known to the skilled person. Tealight cups as meant in the application typically (and preferably) have a diameter of 25 to 75 mm and a height of 8 to 80 mm. The diameter is preferably 33 to 65mm, in particular approximately 38 mm (34-42 mm). The height is preferably 8 to 40 mm, more particularly 10 to 25 mm.
  • the current invention offers a tealight cup comprising a bottom and an outer wall, wherein the bottom comprises an inclined part, characterised in that the inclined part runs from the outer wall and that the inclined part has an incline of > 1°.
  • the radial length of the inclined part is preferably at least 20% of the radius of the tealight cup, in particular at least 25%, more particularly at least 35%.
  • the radial length is preferably at least 45%, more preferably at least 50% of the radius of the tealight cup.
  • the inclined plane has an incline of greater than 3°. The inventor has discovered that an incline of this kind results in better runoff than at an incline of 1°.
  • Inclines as mentioned here indicate the incline in relation to the external surface upon which the tealight cup is placed.
  • the outer wall has an incline of 90°.
  • Inclines between 0° and 90° as described here incline towards the centre of the tealight cup.
  • the inventor has furthermore discovered that an even more complete use of fuel can be achieved if a steep incline is used that is connected to the outer wall. Consequently the invention also offers a tealight cup as described here, wherein the inclined part comprises at least a first inclined plane that is connected to the outer wall and that has an incline of between 15° and 45°.
  • the inclined part comprises at least a first inclined plane that is connected to the outer wall and that has an incline of between 15° and 45°.
  • the first inclined plane preferably meets the outer wall at 40% to 55% of the height of the outer wall and runs to a height of 1% to 10% of the height of the outer wall.
  • the height difference of the first inclined part is 20% to 40% of the height of the outer wall.
  • the radius of the first inclined part is preferably 25% to 45% of the radius of the tealight cup, in particular 30% to 35%.
  • the first inclined part has an incline of 40° to 75°, in particular 60° to 70°, more particularly approximately 65°. These steep inclines in the first inclined part cause optimal runoff.
  • the invention concerns a tealight cup wherein the inclined part further comprises a second inclined plane that connects with the first inclined plane.
  • the steep incline connected to the outer wall herein also called the first inclined plane
  • the second inclined plane preferably has an incline of between 5° and 25°, in particular between 10 and 20°, more particularly between 10° and 15°.
  • the first inclined plane is connected to the second inclined plane.
  • the radial length of the second inclined plane is preferably at least 20% of the radius of the tealight cup.
  • the radial length of the second inclined plane can be chosen depending on the radial length of the first inclined plane.
  • the tealight cup has been executed in such a manner that if it is placed upon an external surface, a (hollow) space is created between the outer wall, the bottom and the external surface. To this end, the outer wall at least runs down to, or below, the last point of the bottom. It has been observed that an even better runoff of the paraffin can be achieved in this way. Without wishing to be bound by the theory, the inventor assumes that the space functions as an insulating space. The air in the space will partially warm up, but dissipation of heat to the ambient air is avoided.
  • the hollow space preferably continues between the first inclined plane and the outer wall.
  • the various preferential embodiments in relation to the first and second inclined plane can of course be combined.
  • a tealight cup according to a particular embodiment (as shown for instance in Fig. 5 ) has:
  • the underside of the outer wall of the tealight cup has been fitted with elements that are able to interact with the top of the outer wall of a second (identical) tealight cup. Because of this, the tealight cups according to the invention can be stacked. This preferably concerns a protrusion (or indentation) on the underside of the outer wall that is able to accommodate the top of the outer wall of a second cup.
  • the inclined part preferably runs substantially from the outer wall to the central surface that supports the wick holder.
  • the invention envisages a tealight cup wherein the sum of the radial length of the central surface that supports the wick holder and the radial length of the inclined part are greater than 90%, for instance greater than 93%, of the radius of the bottom.
  • the bottom can be fitted with centring elements for a wick holder.
  • the inclined part preferably substantially runs to these centring elements.
  • the inclined part furthermore comprises ribs that run radially in the direction of the centre of the bottom. The use of radial ribs offers an additional advantage towards a more complete use of the fuel.
  • the radial ribs are preferably present on the second inclined part as described herein.
  • the radial ribs are not required on the entire surface of the inclined part; for instance by not using them on the first inclined plane. Even in this embodiment, the radial ribs are preferably fitted along the entire circumference of the inclined part.
  • a tealight cup typically contains a central surface to support a wick holder.
  • the central surface is situated 0.1 to 1 mm lower than the lowest part of the inclined part. This permits the fuel to run down along the inclined part to the central surface.
  • the central surface that supports the wick holder contains radially oriented grooves. These grooves are preferably located 0.1 to 1. mm lower than the lowest part of the inclined part. This permits the fuel to run down the inclined part through the grooves to underneath a wick holder. There are preferably 2 to 10 grooves in the central surface.
  • the central surface can possibly also be executed with a slight incline, e.g. 0.5-2°, towards the centre.
  • the tealight cup is preferably executed in a plastic material as this also affects a more complete use of the fuel.
  • a plastic material in principle any plastic material can be used that is sufficiently heat-resistant.
  • the tealight cup is preferably made of polycarbonate, in particular fire-resistant polycarbonate.
  • Fig. 1A shows a tealight cup not according to the invention.
  • This embodiment contains an inclined part (1) that runs from the outer wall almost completely to a central surface that supports a wick holder (12). Moreover, the central surface contains radially oriented grooves (13). Centring elements (8) for a wick holder have also been fitted. As can be seen in the cross section shown in Fig. 1B , the grooves (13) in the central surface (12) are situated lower than the lowest part of the inclined part (1). In this embodiment, the centring elements (8) for a wick holder are situated on the inclined plane. The radial length (2) of the inclined part (1) and the radius (3) of the tealight cup have also been shown.
  • Fig. 1C shows the same embodiment of the tealight cup, but including a wick holder (9) and wick (10). The wick holder (9) is situated between the centring elements (8).
  • Fig. 2 shows another embodiment of the tealight cup, wherein the inclined part contains radially oriented ribs (11).
  • the embodiment shown also contains radially oriented grooves (13) in the central surface that supports a wick holder and centring elements (8) for the wick holder.
  • Figure 3 also shows an embodiment with radially oriented ribs (11) in the inclined part.
  • the central surface (12) that supports a wick holder does not contain any radially oriented grooves.
  • the central surface (12) is situated lower than the lowest part of the inclined part.
  • Fig. 4 shows an embodiment with a first inclined plane (4) with a steep incline and a second inclined plane (5) with a lighter incline.
  • the central surface (12) is situated lower than the lowest part of the inclined part.
  • the radial length (2) of the inclined part (1) consists of the sum of the radial length (6) of the first inclined plane (4) and the radial length (7) of the second inclined plane (5).
  • Fig. 5 also shows an embodiment with a first (4) and a second (5) inclined plane.
  • the second inclined plane contains radially oriented ribs (11) for efficient runoff of the fuel towards the central surface (12).
  • Fig. 6 shows a cross-section of a preferential embodiment according to the current invention, with a first inclined plane (4) with a steep incline and a second inclined plane (5) with a lighter incline.
  • the first inclined plane (4) meets the outer wall at a height (16) between 45 and 55% of the height (15) of the outer wall, and runs up to a height (17).
  • the radial length (6) of the first incline and the radial length of the second incline (7) are also shown.
  • Centring elements (8) permit the centring of a wick holder upon the central surface (12) to support the wick holder.
  • an external surface e.g. a table
  • a hollow space (14) is created between the outer wall, the external surface and the bottom, which consists here of the central surface, the first inclined plane and the second inclined plane.
