Description

There are known fuel containers for gas lighters • in which the cold extrusion produced, Containers made of light metal, open on one side, are closed with a likewise metallic bottom, which is connected to the container jacket by gluing and flanging. This type of production of fuel containers is disadvantageous insofar as an end that has been crimped once can no longer be crimped a second time. Such Containers cannot therefore be refilled on the crimped base by removing the base and re-crimping will.

In the case of a fuel container for gas lighter known from Swiss patent specification No. 311, the jacket is reinforced in its area facing away from the valve, so that a closed ring is formed which complements the jacket. The ring is connected with a floor, on the type of connection between the ring and the bottom of the

unpublished nothing can be extracted. Bs can only be concluded that the two parts are glued to one another, but a sealing ring inserted for this would be superfluous. Also pressing in the soil into the ring would be possible per se, but such a pressing would destroy the sealing ring. on in all cases, however, such a known training is only possible with lighters that are old equipped with their own filling valve. For lighters without a filling valve that would be Factory-made filling only from the bottom The opposite side is possible and experience has shown that this type of filling is far more difficult to carry out than the Filling from the other side.

In order to take into account the peculiarity of gas lighters, fuel containers with a transparent base have also become known, so that the user of such a Lighter can orientate at any time about the level of its container. This will prevent him from being affected by the complete evaporation of the contents almost suddenly «extinction of the flame is surprised. However, even with these versions, in which the container jacket is crimped directly onto the transparent base, or, if it is made of plastic, is glued, the base cannot at least be destroyed of the gas container can be removed, so that a refilling from below is not possible · Also, such containers are not suitable for use in lighters where the Container partially protrudes from the housing.

This is achieved starting from a fuel container for gas lighters, the jacket of which is in its lower one Area is supplemented by a closed ring, which is connected to a floor, possibly designed as a window for checking the respective fuel supply is, in that, for mutual connection, both the jacket and the ring, as well as the ring and the base, are provided with overlapping pre-sprinklers.

However, such containers are only for not taking Goods under pressure, e.g. food, can be used. As a fuel container for gas lighters that are under a Internal pressure of several atmospheres, such containers could because of the low strength of the connection are not used, and the machine production and the machine closure is one according to the invention designed fuel container far simpler than when known container. ,

There are also containers known for food in which one side of a metal ring is embedded in the plastic jacket, the other side of which is crimped over the lid. Such containers also have a fuel container for Gas lighters too low strength, which is caused by embedding of the ring is effected in the plastic jacket.

The inventive design of the container allows It is that by using different materials for the ring and the base the container is extremely pleasing Appearance is given and, moreover, the filling, optionally the refilling, is possible from below. Further the bottom can be made of transparent material, but the ring is made of a wear-resistant material that is suitable for permanent handling Material, such as metal or hard plastic,

* The material of the container shell can be cheap, because it can be easily manufactured light metal or plastic.

The invention is explained below with reference to exemplary embodiments shown in the drawings, wherein 1 and 2 each have an exemplary embodiment of the lower part of a fuel container according to the invention shown half in section, half in view.

According to Fig. 1, the lower edge portion is one of thin The container shell 1 made of light metal is bent over to form an annular outer flange 2 running obliquely upward. In this flange 2 of the shell 1 engages obliquely downwards extending annular inner flange 3 of a pushed-on

Connecting ring k. The ring k, made of plastic or metal, engages with its lower, flange-like inwardly bent edge 5 preferably made of translucent or transparent material bottom 6, the ring k when flanging its edge 5 against a between the lower end of the Container jacket 1 and the bottom 6 inserted seal 7 is pressed. However, this seal can also be omitted if the base consists of at least some elastic plastic. Sealing is then carried out by the base itself, in particular through its Rirtgwulst 8, which rests on the inside of the container shell and acts as a sealing lip. If the connecting ring k is made of metal, it should be non-oxidizing, or at least the ring should have a non-oxidizing layer on its outer surface.

During assembly, the connecting ring k is pushed onto the container jacket 1 until the two planes 2 interlock, then the bottom 6 is with or without

The container is inserted into a lighter, the housing 11 of which covers the jacket 1, but leaves the ring k free. The jacket 1 therefore does not need to be made of high quality material, it is sufficient to choose the material of the ring k so that it is suitable both for the aesthetic effect to be achieved and for touching when pushing in and pulling out, possibly twisting the container. The depth of insertion of the gas container is also limited by the ring k.

In the embodiment shown in FIG. 2, the lower edge region of a container jacket 2o is bent to form an outer flange on which an inner flange 22 of a connecting ring is seated. In the lower area of this ring, a round-encircling projection 2k is formed on the inside, the cross-sectional profile of which essentially corresponds to a sawtooth.
