Abstract

A liquid fuel light has a container (10) for a fuel tank (40), the container having a top end which tapers (11) towards an opening (12) for a wick (30) and an opening at the lower end of the container which is closable with a stopper (20).

Description

  • The present invention relates to a liquid fuel light according to the preamble of claim 1, and a fuel receiving device for such a liquid fuel light.
  • Churches, monasteries and other cultic sites use solid wax candles as well as liquid fueled lights.
  • Such lights are for example from the Swiss patent CH 449 555 and from the utility model DE 200 15 006 U1 known.
  • In DE 200 15 006 U1 Fuel tank made of plastic are described, which is frustoconical at the upper end. The container opening is closed with a metal part, which is fixed by beading on the edge of the plastic container. The metal part has an opening for the passage of the wick or a Dochtfihrungsröhrchens. These lights are, as soon as they are burned empty, only cumbersome to refill, since the wick must be removed and the new fuel must be filled through the narrow Wickdurchdurchführung.
  • In the market liquid wax sacrificial candles are further known, which consist of a cylindrical container whose upper end is designed conical and merges at the top in the wick guide tube. The container is open at its lower end and is closed there with a stopper. This embodiment is shown in FIG. With such liquid wax sacrificial candles, refilling is simplified because the wick does not have to be removed for filling and, if necessary, after cutting off its charred end piece, it can continue to be used. Such a sacrificial candle is shown in FIG.
  • When returning the empty candle for refilling, it may happen that the metal container is slightly bent so that the plug does not close completely tight. Also, temperature fluctuations due to the different expansion coefficients of the materials of container and plug can lead to leaks and thus leakage of the fuel.
  • The present invention is accordingly based on the object, the known liquid fuel light to design so that leakage of the liquid fuel at the stopper is prevented as much as possible. The seal should be easy to handle and inexpensive.
  • The object is solved by the invention according to claim 1. Advantageous developments and special embodiments are the subject of the dependent claims.
  • According to the invention, an inner tank is used in the outer container, which is open at the top; thereby the liquid fuel is kept away from the stopper, whereby leakage at the stopper is effectively prevented.
    Tank and tank are designed substantially cylindrical to obtain a candle shape. However, there are other conceivable, for example, square or other designs. According to the manner known in the art, the container tapers conically in the upper region and is provided at the uppermost end with the Wickdurchdurchführung, which is designed as a tube of a few millimeters in length. The wick is held in the tube by clamping; Alternatively, it can be provided with a thickening, which prevents the wick from slipping inwards.
  • The lower end of the container may have an inwardly directed circumferential ridge, which may be formed by beading the container shell. The plug is preferably provided with a form-fitting adapted to this web circumferential groove, so that the plug is held in its closed position by a latching connection.
  • As a tank, all vessels are conceivable that fit into the container, downwards are completed and open at the top. It makes sense that the tank has the same shape as the stem of the container, but with slightly smaller external dimensions, so that the tank can be inserted into the container from below.
  • The tank and the plug are dimensioned such that in the closed state the tank rests with its upper edge in the tapered region of the container on the inner wall thereof; As a result, it is largely prevented that, due to shaking movements during transport, fuel liquid enters the annular space between the container and the tank.
  • To improve the tightness, one or more sealing rings may be provided. One possible embodiment is an upper sealing ring, which bears against the taper in the interior of the container at the upper end of its shank and abuts against the bottom of the fuel tank with its upper edge. It may alternatively or additionally be provided a lower sealing ring which rests against the bottom of the fuel tank and seals the gap between it and the inner wall of the container.
  • Furthermore, additional sealing surfaces may be provided on which either a sealing ring can rest, or seal directly.
  • For example, it is conceivable to provide a horizontal sealing surface on the taper, against which the tank abuts with its sealing surface. For better sealing can be placed between the sealing surface of the tank and the container a seal. Preferably, in this case, the sealing surface of the tank is provided with a device which fixes the sealing ring, thereby to ensure a precise fit of the sealing ring and to facilitate its installation. The sealing surface of the tank can be formed in that its upper edge is bent radially outwards and forms a flange.
  • At the bottom of the light, a plug is inserted. In this case, the sum of the lengths of the tank and stopper should be selected so that the stopper held in the locking connection can exert some pressure on the inserted seal. is If the seal is at the top of the taper, the pressure from the plug is transferred to the seal via the tank.
  • Also in the plug, a seal can be integrated, for example, by the sealing ring is inserted into an annular groove of the plug.
  • According to a preferred embodiment of the invention, the plug and the tank are integrated with each other. Also in this case, as described above, a seal may be provided on the taper or also on the bottom of the plug.
  • The invention will be described with reference to the embodiments illustrated in the figures and explained in more detail. Show it:

  • Figure 1 shows in longitudinal section a liquid fuel light, as it is currently used in churches, monasteries and sanctuaries as a sacrificial candle. It consists of a cylindrical container 10, whose upper end is designed as a conical taper 11 and merges at the top into the wick guide tube 12. The container is open at its lower end 13 and is closed there with a plug 20. The wick 30 is held in the wick guide tube 12 by clamping. With such liquid wax sacrificial candles, refilling is simplified because the wick does not have to be removed for filling and, if necessary, after cutting off its charred end piece, it can continue to be used. Usually cylindrical containers are used, but there are other designs with z. B. square, hexagonal or octagonal cross-section possible.
  • FIG. 2 shows a first embodiment of the invention. Inside the container 10 is a tank 40 containing the liquid fuel 70, e.g. liquid paraffin or oil. The tank 40 is adapted in shape to the container 10. The distance of its jacket 41 from the inner wall 14 of the container is small and sized so that it can be easily inserted into the container without friction. The tank preferably has such a length that, when inserted, its upper edge 42 contacts the inner wall 14 of the container in the region of the conical taper 11, so that during transport due to shaking movements no or only very little fuel from the tank into the intermediate space between tank and container can get.
  • At the lower end 13 of the container, a projection 15 may be arranged. This projection is radially inwardly and serves to form a latching connection between the container and the stopper. Preferably, the projection is circumferential and is formed by bending or flanging the lower edge of the container.
  • The plug is provided for the locking connection with a form-fitting adapted to the projection 15 groove 23.
  • Figures 3A to 3E show various possibilities for sealing the tank to the container. For a better overview, the wick and the liquid fuel are not shown in these and the following figures.
  • According to Figure 3A, a sealing ring 50 is disposed in the container at the transition from the shaft 16 to the conical taper 11, to which the tank with its upper edge 42 bears sealingly. The size of the ring is wise to choose so that it rests inside the container 10 without slipping and is pushed by its own size to the edge.
  • The upper edge 42 of the tank is at least smoothed, better still flattened or bent slightly inwards, so that the sealing ring 50 can conclude optimally.
  • According to Figure 3B, the tank is provided at the top with a conical indentation 43; and the sealing ring 50 is located between this indentation 43 and the conical taper 11 of the container.
  • According to FIG. 3C, the embodiment of FIG. 3B can be modified such that a groove 44 for receiving the sealing ring 50 is arranged on the tank in the area of the intake 43. This groove secures the seat of the sealing ring and thus improves the seal as well as the handling of the sealing ring during insertion of the filled tank.
  • According to Figure 3D, the tank at the top of an outwardly projecting flange 45 which faces a radial indentation 17 of the container, between which the sealing ring 50 is arranged.
  • Figure 3E shows a variant of the seal that can be applied to plastic tanks. The upper edge of the tank drains into a thin sealing lip 46 which abuts against the inner wall of the container in the region of the conical taper 11 and thereby seals the tank.
  • FIG. 4 shows a further embodiment in which the sealing takes place in the lower area of the container on the stopper 20 with a sealing ring 52. The plug 20 has a tubular upper end portion 21 which pushes the sealing ring 52 into the space between the spherical sectioned bottom 47 of the tank and the inner wall 14 of the container, thereby sealing the gap 60 and thus preventing leakage of fuel.
  • The curved shape of the tank bottom 47 causes a spreading of the sealing ring under the pressure exerted by the plug and thus leads to a good seal on the inner wall of the container. For this purpose, the bottom 47 may also be designed cone-shaped instead of spherical.
  • FIG. 5 shows a further possibility for sealing the intermediate space 6. The plug has a circumferential groove 23 into which the sealing ring is inserted.
  • The seal on the plug can be combined with a seal at the top of the tank.
  • Figure 6 shows a preferred embodiment in which the plug 20 and the tank 40 form an integral component. It is preferably made of plastic. For the sealing not only the embodiment shown in Figure 6 are considered, but also all other variants described above; In particular, the formation of the upper edge of the tank as a sealing lip leads to a further reduction in the number of components and thus the assembly effort.
  • FIG. 7 shows in cross-section a preferred embodiment of the seal. It is conically shaped on its upper side and thus adapted to the inner wall of the container in the region of the taper 11. On its underside, it has an annular groove 51 into which the upper, annular edge 42 of the tank 40 engages in the installed state. The width of the annular groove is preferably slightly less than the wall thickness of the tank 40, so that the seal bears against the wall of the tank with tension.
    In the figure 8 an embodiment provided with this seal is shown.
