Tobacco product with fluorescent or phosphorescent substances

Abstract

A filter cigarette includes a filter, a filter wrapper material enwrapping the filter, a tobacco rod, a tobacco rod wrapper material enwrapping the tobacco rod, and a mouthpiece wrapper material. The mouthpiece wrapper material enwraps at least a subregion of the filter wrapper material and has an upper surface which forms at least part of the surface of the filter cigarette. The filter cigarette has at least one fluorescent or phosphorescent substance in the region of the mouthpiece wrapper material below the upper surface of the mouthpiece wrapper material. The mouthpiece wrapper material has an opening in at least one region of the fluorescent or phosphorescent substance or is embodied as a translucent or transparent film, so that this at least one region is visible from the outside of the filter cigarette.

AI Technical Summary

Benefits of technology

This patent is about making tobacco products safer and easier to identify. The invention uses fluorescent or phosphorescent substances that are colorless or match the color of the tobacco product they are applied to. The substances may glow in the dark after being stimulated and can be made visible only in the dark or muted light. They are applied to the mouthpiece of filter cigarettes or the outermost layer of the finished product. The invention does not change the appearance of the tobacco product in daylight. The use of these substances can help to quickly detect the tobacco product in the dark and increase its protection against counterfeiting or identify important information about it.

Problems solved by technology

The disadvantage is that the ready-to-use cigarette has no luminescent properties, or that additional packaging material is required on each individual filter cigarette.

The disadvantage is that compared to the substances of the luminescent coating, a coating with lacquer can only be produced in a dense layer in a very elaborate manner which requires a time-consuming coating with a relatively thick lacquer layer.

In addition, this coating with lacquer can interact with the luminescent substances through the solvent of the protective lacquer, which can result in the attenuation of the luminous effect, or causes the luminescent substances to migrate with the solvent of the protective lacquer into deeper layers of the filter cigarette, or fine structures of the fluorescent coating become “washed out” and thus blurred.
