CONE WITH TOBACCO PLUG FILTER

摘要

A smoking article and method of manufacture provides a sheet of smokable material having a plurality of edges. One or more score or cuts are made in the sheet that each extend a partial distance from a first said edge toward a second said edge, the score or cut separating large and small sections of the sheet. A hinge is defined by a portion of the sheet of smokable material that is next to a score or cut, said hinge joining the large section to the small section. A conically shaped form is provided for shaping the sheet. The form has an outer surface, a large diameter end, a small diameter end, and a cavity that extends to said small diameter end. Corrugations on the small section of the sheet enable the small section to be fitted into the cavity via the small diameter end. The hinge enables the sheet to fold when the small section occupies the cavity in an assembled position wherein the large section is wrapped around the form outer surface. In the assembled position, the corrugations enable the small section to gather together to define a filter.

1. A smoking article, comprising:
a) a sheet of smokable material having a plurality of edges; b) one or more score or cuts in the sheet that each extend a partial distance from a first said edge toward a second said edge, the score or cut separating large and small sections of the sheet; c) a hinge defined by a portion of the sheet of smokable material that is next to a score or cut, said hinge joining the large section to the small section; d) a conically shaped form that has an outer surface, a large diameter end, a small diameter end, and a cavity that extends to said small diameter end; e) corrugations on the small section of the sheet that enable the small section to be fitted into the cavity via the small diameter end; f) the hinge enabling the sheet to fold when the small section occupies the cavity in an assembled position, wherein in said assembled position the large section is wrapped around the form outer surface to make a cone having a larger diameter end and a smaller diameter end; and g) wherein the assembled position, the corrugations enable the small section to gather together to define a filter positioned at the smaller diameter end of the cone.
