Opposed seam electrically heated cigarette smoking system
An electrically heated cigarette smoking system includes a cigarette that is formed with a tobacco rod portion, a filter tube portion, a tobacco mat layer wrapped around the tobacco rod portion and the filter tube portion with opposite ends of the tobacco mat layer abutting along a seam parallel to the central axis of the cigarette and cigarette paper wrapped around the tobacco mat layer and bonded to itself along an overlapped seam that is offset from the seam of the tobacco mat layer. The method of manufacturing the cigarette includes wrapping the tobacco mat layer and the cigarette paper around the tobacco rod portion and the filter tube portion on a single, high-speed machine.
1. An electrically heated cigarette for an electrically heated cigarette smoking system, comprising:
a tobacco plug portion;
a filter tube portion; a tobacco mat layer wrapped around said tobacco plug portion and said filter tube portion, with opposite ends of said tobacco mat layer abutting along a seam parallel to the central axis of the cigarette; and
cigarette paper wrapped around said tobacco mat layer and bonded to itself along an overlapped seam that is circumferentially offset from the seam of the tobacco mat layer, and wherein the overlapped seam of the cigarette paper is antipodal to the abutting seam of the tobacco mat layer.
2. The electrically heated cigarette of claim 1 , wherein said tobacco plug portion is spaced from said filter tube portion to form a cavity portion in the cigarette.
3. The electrically heated cigarette of claim 1 , wherein said filter tube portion comprises a hollow cellulose acetate tube and a metal foil lining.
4. The electrically heated cigarette of claim 1 , further including a tipping comprising a free-flow filter located adjacent said filter tube portion and a mouthpiece filter located at the distal end of the tipping from the filter tube portion, said free-flow filter and said mouthpiece filter being joined together by a plug wrap, and the tipping being joined to the filter tube portion by tipping paper.
5. An electrically heated cigarette for an electrically heated cigarette smoking system, comprising:
a tobacco plug portion;
a filter tube portion; a tobacco mat layer wrapped around said tobacco plug portion and said filter tube portion, with opposite ends of said tobacco mat layer abutting one another; and
cigarette paper wrapped around said tobacco mat layer and bonded to itself along an overlapped seam with a single layer of said cigarette paper overlying said abutment of the opposite ends of said tobacco mat layer, and wherein the overlapped seam of the cigarette paper is antipodal to said abutment of the opposite ends of said tobacco mat layer.
6. The electrically heated cigarette of claim 5 , wherein said tobacco plug portion is spaced from said filter tube portion to form a cavity portion in the cigarette.
7. The electrically heated cigarette of claim 5 , wherein said filter tube portion comprises a hollow cellulose acetate tube and a metal foil lining.
8. The electrically heated cigarette of claim 5 , further including a tipping comprising a free-flow filter located adjacent said filter tube portion and a mouthpiece filter located at the distal end of the tipping from the filter tube portion, said free-flow filter and said mouthpiece filter being joined together by a plug wrap, and the tipping being joined to the filter tube portion by tipping paper.
9. An electrically heated cigarette for an electrically heated cigarette smoking system, comprising:
a tobacco plug portion;
a filter tube portion; a tobacco mat layer wrapped around said tobacco plug portion and said filter tube portion, with opposite ends of said tobacco mat layer abutting one another; and
cigarette paper wrapped around said tobacco mat layer and bonded to itself along an overlapped seam that is circumferentially offset from the abutment of the opposite ends of said tobacco mat layer, and wherein the overlapped seam of the cigarette paper is antipodal to the abutment of the opposite ends of said tobacco mat layer.
10. The electrically heated cigarette of claim 9 , wherein said tobacco plug portion is spaced from said filter tube portion to form a cavity portion in the cigarette.
11. The electrically heated cigarette of claim 9 , wherein said filter tube portion comprises a hollow cellulose acetate tube and a metal foil lining.
12. The electrically heated cigarette of claim 9 , further including a tipping comprising a free-flow filter located adjacent said filter tube portion and a mouthpiece filter located at the distal end of the tipping from the filter tube portion, said free-flow filter and said mouthpiece filter being joined together by a plug wrap, and the tipping being joined to the filter tube portion by tipping paper.
