Pre-Roll Body Having Integral Ceramic Mouthpiece
A pre-rolled cigarette includes a pre-roll body and a filtering mouthpiece preassembled with the pre-roll body at an attachment end. The filtering mouthpiece includes an open mouthpiece end disposed opposite to the attachment end, and a passage providing fluid communication between the open mouthpiece end and one or more filtration holes disposed through the attachment end.
1 . A pre-rolled cigarette, comprising:
a pre-roll body; and
a filtering mouthpiece preassembled with the pre-roll body at an attachment end;
wherein the filtering mouthpiece includes an open mouthpiece end disposed opposite to the attachment end, and a passage providing fluid communication between the open mouthpiece end and one or more filtration holes disposed through the attachment end.
2 . The pre-rolled cigarette of claim 1 , wherein the filtering mouthpiece is preassembled with the pre-roll body via an airtight seal.
3 . The pre-rolled cigarette of claim 2 , further comprising a ring of flexible material having an adhesive on a surface thereof, wherein the filtering mouthpiece is preassembled with the pre-roll body via an airtight seal formed by the ring of flexible material wrapped around and adhered to a side surface of the filtering mouthpiece proximate to the attachment end and to a side surface of the pre-roll body proximate to an end of the pre-roll body.
4 . The pre-rolled cigarette of claim 1 , wherein the flexible material is selected from the group consisting of natural paper, synthetic paper, vinyl, polypropylene (PP), and polyethylene (PE).
5 . The pre-rolled cigarette of claim 1 , wherein the filtering mouthpiece is manufactured from a ceramic material.
6 . The pre-rolled cigarette of claim 5 , wherein the pre-roll body is filled with plant material that is ground into particulate having a predetermined average maximum particle dimension, and the one or more filtration holes are sized during manufacturing of the filtering mouthpiece to filter the particulate.
7 . The pre-rolled cigarette of claim 6 , wherein the filtering mouthpiece is manufactured by injection or compression molding.
8 . The pre-rolled cigarette of claim 1 , wherein the one or more filtration holes have a maximum cross-sectional dimension in a range from about 0.5 mm to about 1.5 mm.
9 . A pre-rolled cigarette, comprising:
a pre-roll body;
a filtering mouthpiece preassembled with the pre-roll body at an attachment end, wherein the filtering mouthpiece includes an open mouthpiece end disposed opposite to the attachment end, and a passage providing fluid communication between the open mouthpiece end and one or more filtration holes disposed through the attachment end; and
a ring of flexible material having an adhesive on a surface thereof, wherein the filtering mouthpiece is preassembled with the pre-roll body via an airtight seal formed by the ring of flexible material wrapped around and adhered to a side surface of the filtering mouthpiece proximate to the attachment end and to a side surface of the pre-roll body proximate to an end of the pre-roll body.
10 . The pre-rolled cigarette of claim 9 , wherein the flexible material is selected from the group consisting of natural paper, synthetic paper, vinyl, polypropylene (PP), and polyethylene (PE).
11 . The pre-rolled cigarette of claim 10 , wherein the filtering mouthpiece is manufactured from a ceramic material.
12 . The pre-rolled cigarette of claim 11 , wherein the pre-roll body is filled with plant material that is ground into particulate having a predetermined average maximum particle dimension, and the one or more filtration holes are sized during manufacturing of the filtering mouthpiece to filter the particulate.
13 . The pre-rolled cigarette of claim 11 , wherein the filtering mouthpiece is manufactured by injection or compression molding.
14 . The pre-rolled cigarette of claim 8 , wherein the one or more filtration holes have a maximum cross-sectional dimension in a range from about 0.5 mm to about 1.5 mm.
15 . A filtering mouthpiece adapted to be preassembled with a pre-roll body via an airtight seal, the mouthpiece comprising:
an open mouthpiece end disposed opposite to an attachment end, and a passage providing fluid communication between the open mouthpiece end and one or more filtration holes disposed through the attachment end.
16 . The filtering mouthpiece of claim 15 , wherein the filtering mouthpiece is manufactured from a ceramic material by injection or compression molding.
17 . The filtering mouthpiece of claim 16 , wherein the one or more filtration holes are sized during manufacturing of the filtering mouthpiece to filter particulate having a predetermined average maximum particle dimension.
18 . The filtering mouthpiece of claim 17 , wherein the one or more filtration holes have a maximum cross-sectional dimension in a range from about 0.5 mm to about 1.5 mm.
19 . The filtering mouthpiece of claim 16 , wherein the filtering mouthpiece tapers from the attachment end toward the open mouthpiece end.
20 . The filtering mouthpiece of claim 15 , further comprising a ring of flexible material having an adhesive on a surface thereof, wherein the ring of flexible material is adhered around a side surface of the filtering mouthpiece proximate to the attachment end to form an airtight seal therewith and is adapted to be wrapped around and adhered to a side surface of the pre-roll body proximate to an end of the pre-roll body to form an airtight seal therewith, wherein the flexible material is selected from the group consisting of natural paper, synthetic paper, vinyl, polypropylene (PP), and polyethylene (PE).
