Definitions
- the invention relates to a filter cigarette, the filter of which is surrounded by a filter wrapping paper which encloses a tip coating, the inside of the filter wrapping paper being coated with metal, in particular with aluminum.
- the invention is thus based on a filter cigarette, the filter of which is surrounded by a filter wrapping paper which encloses a tip coating, wherein air can penetrate into the filter through the filter wrapping paper.
- the coating is applied only to part of the filter wrapping paper, so that air can penetrate through it into the filter.
- the metallization can be carried out by applying in particulate form and / or by suitably applying flat patterns to the wrapping paper on the paper surface, but not by completely coating the filter wrapping paper.
- a partial coating of the filter wrapping paper with metallic surfaces brings about a selective reduction in the carbon monoxide content of the main stream smoke.
- Fig. 1 is an inventive filter wrapping paper with aluminum strips and
- Fig. 1 aluminum strips were applied to a commercially available highly porous paper for wrapping cigarette filters (Papierfabrik Wattens GmbH, QNo. 27400) with an air permeability of 6000 CU using a hot-foil process.
- the width of the wrapping paper was 26.5 mm
- the width of the aluminum strip was 1 mm.
- the distance between the strips was 1 mm.
- Filter rods for cigarettes were manufactured in a manner known per se from a bobbin with a length of approx. 1000 m and with industrial acetate cable.
- the drawing shows the structure of such a filter rod made of acetate cable 1, wrapping paper 2 and mouthpiece covering 3, with 4 the aluminum strips according to the invention are designated.
- Cigarettes were machine made using these filter sticks. For comparison purposes, cigarettes were produced on the basis of the same composition with regard to filters, cigarette paper and tobacco mixture, but without a previous zone-wise coating of the filter wrapping paper. The manufactured cigarettes were smoked in a smoke laboratory under standardized conditions. The smoke constituents of the main smoke stream have a selectively and significantly lower carbon monoxide content, as shown in Table 1.
- Tab. 1 Results of standardized smoking of cigarettes with (modified) and without (standard) aluminum strips 4 on the filter wrapping paper 2.
- FIG. 2 shows another embodiment according to the invention.
- the filter wrapping paper 2 was coated with aluminum in a finely divided manner, with the structure of the filter rod remaining the same with respect to the acetate cable 1 and the mouthpiece covering 3, but the aluminum layer 5 was highly porous.
- This type of aluminum coating ensures that the air permeability of the filter wrapping paper is sufficiently maintained, so that, as in the exemplary embodiment in FIG. 1, sufficient air can enter the side of the cigarette filter.
- Tab. 2 Results of standardized smoking of cigarettes with (modified) and without (standard) finely divided, highly porous aluminum coating 5 on the filter wrapping paper 2.
- the invention combines the known advantage of filter ventilation with an effect due to the metal coating.
- the two exemplary embodiments show that the effect can be detected regardless of the type of metal coating, as long as the combination of air permeability of the filter wrapping paper and the metal coating of the filter wrapping paper mentioned in claim 1 is ensured.
- the invention in this sense is not limited to the exemplary embodiments shown, but rather includes all possible combinations of the exemplary embodiments shown here and other exemplary embodiments within the meaning of claim 1.
