Method for marking a glass material and a corresponding glass material

PROCEDURE FOR MARKING a GLASMATERIALES AND a GLASS MATERIAL the invention concerns a procedure for marking a Glasmateriales. The invention concerns also a marked glass material.

In different ranges of the consumer goods industry frequently the problem exists that on the market plagiarisms of branded articles arise. Then the difficulty for the enterprise concerned exists to differentiate the own original from the plagiarism to. This is in particular therefore the case, since also the packing was almost perfectly immitiert. For example cases are accordingly well-known, with which products in glass packing are provided with stock. The glass packing was original-faithfully copied thereby.

It is from there task of the invention, a procedure for marking a Glasmateriales to create and/or a glass material the manufacturer of the original product recognizing its product made possible, which cannot be copied however for a potential counterfeiter or only at very high expenditure.

For the solution of the task a procedure for marking a Glasmateriales is suggested, with which a chemical element or a group is admitted to the glass material in the schmeizförmigen condition by chemical elements (in the following likewise briefly chemical element called), whereby the chemical element in the rigid condition of the glass emits a light or a flash spectrum outside of the wave band of the visible light. Thus so easily individualizing cannot be regarded to the manufactured glass article. The glass material can be completely colored depending upon kind of application.

Conceivably it is however also that determined only completely, for example punctiform ranges characterized and for is more wrongly with difficulty discoverable.

As chemical element for example a substance use can find, which fluoresziert within the infrared light range. Such substances are for example antimony, lead oxide or zinc oxide.

Additionally or alternatively it can be also intended that a chemical element is assigned to the melt, in the rigid condition of the Glasmateriales in the ultraviolet light range fluoresziert. In particular the elements from the group of the oxides of the Seltenden ground connection can be used.

Due to the multiplicity of the substances usable as chemical element can be created a multiplicity of light spectral regions, by means of those an individualizing of the Glasmateriales be taken place can. Additionally also still the weight percentage portion of the chemical element in the glass material can be varied, so that the number of different possible spectral regions can be strengthened. This makes possible to carry out the user in regular or irregular intervals a color change of the glass article. Thus the falsification safeness is continued to increase.

According to invention it can be intended that the chemical element of containing glass bodies is manufactured that this glass body in the liquid, doughy or solid state is attached into or to a feed gas not marked with the chemical element in or. The glass body can be trained accordingly in a recess or a breaking through of the carrier glass. Conceivable is it also that a glass body is manufactured and pressed into a feed gas. This must take place in the doughy condition of the carrier glass. Further it is also conceivable that the glass body is out-arranged as supporter label.

The invention concerns also a glass material, which is manufactured after one of the managing procedures.

Further the task of the invention also of a glass material drawn, which exhibits a glass basis substance, into the one chemical element or a group by chemical elements brought is and whereby the chemical element in the glass material a light or a flash spectrum outside of the wave band of the visible light emits.
