Patent number: 9392818Abstract: The invention relates to a cigarette paper for self-extinguishing cigarettes. The cigarette paper comprises bands onto which a material reducing the diffusion capacity is applied, wherein a band comprises two band-like outer zones (18a, 18b) and a band-like central zone (20) therebetween. The said material is applied substantially over the entire surface up to the outer zones (18a, 18b) of the band (10). The aforementioned material is additionally applied to at least 70%, preferably at least 75% and/or at most 95%, preferably at most 90% of the surface of the central zone (20). The surface (22) to which the said material is applied is path-connected. The surface of the central zone (20), to which the said material is applied is likewise path-connected.Type: GrantFiled: October 22, 2013Date of Patent: July 19, 2016Assignee: delfortgroup AGInventors: Roland Zitturi, Dietmar Volgger

Patent number: 9392817Abstract: The invention relates to a paper that disintegrates quickly in water, for use as a filter material or filter wrapper paper of a cigarette filter. At least 80 wt % of the paper is formed by cellulose fibers. Of the cellulose fibers, at least 80 wt % are a mixture of long fiber pulp and mercerized pulp. 0 to 90 wt % of the content of the mixture is formed by mercerized pulp, and the rest is formed by long fiber pulp. The cellulose fibers of the mixture have a freeness of at most 30° SR according to ISO 5267. In the disintegration test using an apparatus as described in TAPPI T 261, the paper exhibits a disintegration of at least 60% after 30 seconds.Type: GrantFiled: May 14, 2013Date of Patent: July 19, 2016Assignee: delfortgroup AGInventors: Stefan Bachmann, Dietmar Volgger, Dieter Möhring, Kannika Pesendorfer, Guido Reiter

Publication number: 20160198761Abstract: A cigarette paper is disclosed that has at least one treated area to which a composition that contains filler particles or a mixture of filler particles is applied. The diffusion capacity thereby in the at least one treated area is less than in an untreated area of the cigarette paper, wherein at least 20% by weight, preferably at least 50% by weight and particularly preferably at least 70% by weight of the filler particles in the treated area are formed by a filler with a flaked shape or a filler with a cubic shape. Additionally or alternatively, a filler with a scalenohedral or rhombohedral crystal structure can be used, as long as the particle size distribution is selected appropriately.Type: ApplicationFiled: August 7, 2014Publication date: July 14, 2016Inventors: Dietmar Volgger, Roland Zitturi
