Abstract:
1. A method of making a cigarette comprising the steps of: providing a continuous filter rod having at least one cavity within the continuous filter rod, wherein at least one cavity is defined by a filter element comprising filter material; cutting the continuous filter rod transverse to its longitudinal axis through the center of the at least one cavity to form at least two filter rods each with an open cavity end; inserting at least one breakable capsule into each of the open cavity ends of the at least two filter rods such that the at least one breakable capsule is affixed in the cavity by friction between the capsule and the filter material defining the cavity, the at least one breakable capsule having a diameter between about 3 mm and about 4 mm and comprising a gelatin outer shell and a liquid internal payload comprising a flavoring agent and a triglyceride diluting agent, the at least one breakable capsule having a crush strength between about 750 grams and about 5000 grams; connecting the open cavity ends of the at least two filter rods to at least one filter segment to form at least one plug tube combined continuous rod such that each cavity is completely enclosed by filter material; providing at least one tobacco rod; connecting the at least one tobacco rod to at least one end of the at least one plug tube combined continuous rod; and cutting the at least one plug tube combined continuous rod transverse to its longitudinal axis through the at least one filter segment to form at least one cigarette, wherein the capsule is located within an airspace within the filter element and wherein the filter element is sufficiently resilient to return to a substantially cylindrical shape and maintain said cavity after being squeezed.
