"Walls for portable containers made of plastic or similar substances. "

The present invention relates to particular arrangements which are to be met in the manufacture of winches for portable plastic containers, as z. E.g. for transportation used by liquid fuels. Purpose of these orders is, for the embossing resulting from the accumulation of electrostatic Charges on moving plastic races and the resulting evoked phenomena result in obtaining a flawless final solution «

These particular arrangements consist mainly of dajpin that these plastic walls are reinforced with a last of ladders, or interspersed, which are connected to the earth

A special feature of the invention is that the aforementioned rush of electrical conductors, which are connected to the earth, or can be connected to it, is in Transverse direction extends over the entire circumference of the container. This can be achieved in a number of ways.

The most economical and at the same time the most expedient AuafiBbrang consists in the fact that during the making of the pias

tikwand one or more electrical conductors in one or more siftings are wrapped so that they are in the wall thickness be completely embedded.

According to the invention, a very thin metal wire is used used, which is helically wound during manufacture of the container and arranged so that it is attached to an or can be placed on the ground in several places

The details of the method to be used, such as The properties of the metal wire and the pitch of the very cone winding also depend essentially on the special requirements of the respective applications. In particular, the portable plastic containers can hold very different ones Fit, and for the carriage of diverse liquid, gaseous, pulpy or powdery products will. Such containers can also be mounted on slow or fast vehicles and they can be used be determined under very different climatic circumstances.

Another aspect is the question of the economic viability of the means used, provided that the proper effectiveness of the safety measures in question is not impaired in any way. With that in mind the applicant, continued their research and are in the process of doing so various new conditions have emerged which represent a substantial advance in this area of technology.

For commercial reasons, the use of such safety grounding nets has been found for both circular tanks as well as for containers with an elliptical cross-section as a

Massively exposed, the electrical! conductors helically in one or more layers either continuously or in places wind up interrupted, the pitch of the requirements depends on the application at hand,

In a preferred embodiment, the container armored on its entire length with such a Hetz, which by helically winding one or more lietalldrraht is produced.

The advantage of such an arrangement is primary to see in it that it leads to a quick and comfortable work process and that in this way it is possible that Distribute safety grounding network as evenly as possible and to capture the largest possible surface, so to speak, This working method also has the essential advantage that by determining the pitch of the winding accordingly, the ratio between metal and plastic mass can easily change or adjust without changing the wire diameter or the to have to change the means used for execution.

The helical wire winding also has the advantage of that this method can be used practically independently of the shape and dimensions of the container.

Another advantage of the helical wire winding can be seen in the fact that you can also use two or arrange several such windings with opposite screwing directions can, so that a real Masehennetz in several on top of each other! resulting layers, which each time through a plastic layer are separated from each other.

In one embodiment one could e.g. E.g. a first -

ζ. E.g. make a right-hand winding and then a Arrange a second plastic layer of the same thickness, whereupon a e.g. left-handed second winding can be arranged, which is finally covered by a third layer of plastic, with the same or different wires for the two windings Type and diameter meter can be used.

One will understand that in this way one is security can increase to a very high degree without the steadiness, or · the resistance as well as the other properties of those made of plastic, especially reinforced Polystypsa made container harm.

In certain Ausfülfciruiigsformen such can or multilayer helical wire windings are produced in sections, each section being separated from the earth connected is.

As a simple example, an embodiment shown in the accompanying drawings will be described below is shown schematically? show it:

Figure 1 viewed from the front and partly in longitudinal section, the elements from which a container protected according to the invention can be put together}

Figure 2 shows a wall part designed according to the invention in perspective.

In Figure 1, the container 1 contains a cylindrical Body 2 and two curved side walls 3, 4, these parts each having at least one helically wound in the Wall embedded electrical conductors 5 are provided with the earth connections are shown at 6, for example.

Figure 2 shows in particular the characterizing features of the invention even wall, wherein embedded in the wall thickness very thin electrical conductors are particularly% highlighted.

Of course, the metal parts that have the task of absorbing static electrical charges can accumulate and to leave, distributed, wound up or arranged in any other way.

Wire windings wound in the same direction or in opposite directions can also be used arrange them in different layers, or form different electrical subnetworks that are independent of one another.

Finally you can look for another variant two wire coils wound in opposite directions that touch each other, form a conductive mesh network.

The invention extends not only to the against static accumulation of charges, but also on any container constructed from it.
