Packaging container made of electrically conductive soft foam

Electrostatic charging of various objects, especially made of metals, often leads to harmful or undesirable effects. Printed Circuits and transistors can even lose their functionality due to an electrostatic charge.

The elektrot static charging of the aforementioned items can be done, for example, when these items are in the for storage and transport Serving packaging items are inserted. Charging can also take place during transport, in which more or less strong vibrations always occur, which lead to friction phenomena.

Packaging containers, which decisively counteract the charging of the packaged objects

or even promote their discharge were not previously known.

The task of the innovation was to provide such packaging containers.

The innovation relates to a packaging container made of electrically conductive foam.

A flexible polyurethane foam is preferably used as the foam based on polyether, which, as in the

f 21 52 546.2 is described, is made electrically conductive. This black-colored foam has dm of about 0.03 kg / a weight, an electrical resistance range of 10 ^ ohms and up to 12O ⁰ C temperature resistant.

The packaging container according to the innovation corresponds to the conventional ones with regard to its shape and dimensions Packaging containers.

The objects to be packaged can be packed as they are in the container or in the Foam can be inserted into it. Due to the electrical conductivity of the foam from which the There is a packaging container according to the invention, the objects are prevented from being pushed in in the compartment or during transport. In addition, the foam builds up static electricity on contact with charged parts

In the photographic a form of execution of the

Verpaokungsbehältiges according to the invention shown. The container therefore has a simple design, dis wsgsTi the · flexible nature of the soft foam es (in the present case a flexible polyurethane foam) a comfortable introduction of the objects guaranteed.

The packaging container according to the invention can of course have any other dimensions and proportions than those shown in the drawing. It can also be equipped with a wide variety of locking mechanisms. For example, the opening can after The packaging of the objects by inserting an Ie is uniform part of the same electrically conductive Foam like the rest of the way to be closed »

Bas the upper part of the packaging container according to the invention: Like the rest of the part, it can be made of an electrically conductive foam or an electrically conductive one conductive fleece.

The packaging container is particularly suitable for the packaging and dispatch of precious metal objects, especially of assembled circuit boards, as well as of printed circuits and transistors.
