Water filter description

The invention relates to filter elements and particularly to an improved water filter for cigarettes. The filter element of this invention contains a frangible or collapsible module having contained therein a liquid such as distilled water. The water is dispersed into the tobacco portion of the cigarette. Thus wetting or dampening the tobacco. The wet tobacco then acts as a filter for tobacco smoke generated and sucked through the cigarette.


FIG. 1 is a perspective new of a cigarette having an embodiment of the filter element of this invention.

FIG. 2 is a cross-sectional view of FIG. 1

FIG. 3 illustrate the release of water into the tobacco portion of the cigarette.


FIGS. 1 and 2 illustrates the water filter of this invention in a cigarette: Frangible or crushable capsule 2 contains a liquid such as distilled water. Capsule 2 is embedded in a resilient reinforcing sleeve 3 of heavy cigarette paper. Crush band 6 has indicia printed thereon indicating where pressure must be exerted on capsule 2 so as to release the water into tobacco charge 4. At the lighting end the cigarette has sleeve 5 wrapped about sleeve 3 in a telescopic relationship, as illustrated. The mouthpiece 1 is filled with an absorbent material such as cellulose or other material.

FIG. 3 illustrates the crushing of the capsule 2 and the tapping of the cigarette portion 5 on a hard surface. This tapping will cause the water to be dispersed in the tobacco.
