FILTER TIP, TUBES, AND CONES

Abstract

A filter strip is provided for rolling sheets to construct custom cigars and/or cigarettes. The filter strip may be made of a deformable material which can be positioned on one end of the rolling sheet. The filter strip can be folded in a zig zag or spiral filter section with open section located longitudinally below to form a filter tip. The filter tip can assist the user in rolling by hand a substantially cylindrical or conical cigar or cigarette. The filter tip prevents tobacco filler material from being drawn through the cigar or cigarette and into a user's mouth, and permits the entire amount of tobacco filler to be consumed/smoked without risking burned hands and/or lips.

In various embodiments the ratio of the lengths can be about 1.1, 1.2, 1.25, 1.3, 1.4, 1.5, 1.6. 1.75, 1.8, 1.9, 2.0, 2.25, 2.5, 2.75, 3.0, 3.5, 4.0, 4.5, 5.0, 6, 7, 8, 9, and 10. In various embodiments the ratio can be a range between any two of the above referenced ratios.

[0115] FIG. 3 shows strip 100 of FIG. 2 schematically indicating (arrow 402) that removable portion 400 is being removed from strip 100. As shown in FIGS. 4 and 7, the rolling strip 100 can have removable portion 400. FIG. 4 shows strip 100 with removable portion 400 removed and leaving the remaining portion of strip 100. FIG. 7 shows strip 100 with the removable portion 400 removed (schematically indicated by arrow 402) and leaving the remaining portion.

[0116] In one embodiment filter section 550 of cylindrical filter tip 500 can be folded similar to a hand fan as shown in FIG. 9. In one embodiment filter section 550 can be spirally rolled as shown in FIG. 13.

[0117] In forming filter tip 500, as schematically indicating in FIG. 4, length 170 of filter strip 100 can be folded upon itself (such as by using perforation or fold lines 310 to assist in the folding and schematically indicated by zig zag arrow 312). Length 170 can be placed between a users thumbs and forefingers and is folded alternatively (or in an undulating manner) toward length 180. The number of times that length 170 of filter strip 100 can be folded upon itself depends both on length 170, and the size of the folds (e.g., the distance between fold lines 310).

[0118] After the folding of length 170, length 170 and length 180 are then rolled upon themselves (schematically indicated by arrow 106) until filter tip 500 is formed as shown formed in FIG. 9.

[0119] FIG. 9 shows a substantially cylindrical finished filter tip 500 which can include first end 510, second end 520 and have a height 200. Filter tip 500 can include filter section 550 having a height 220 and open section 570 having a height 240. Height 220 and height 240 correspond to the same numbered heights in filter strip 100 shown in FIGS. 1-4.

[0120] Finished filter tip 500 can be either cylindrical or conical. If filter tip 500 is to be conical it is preferred that semicircular filter strip 100 shown in FIGS. 5-8 be used to form filter strip 100.

[0121] FIG. 5 is a top view of semicircular filter strip 100 which is punched in an encasing form 102 having a removable portion 400. FIG. 6 is a top view of semicircular filter strip 100 which is punched in an encasing form 102 having a narrowed portion 240 removed. FIG. 7 shows semicircular filter strip 100 FIG. 6 with a removable portion 400 being removed from the remaining portion (removal schematically indicated by arrow 402). FIG. 8 shows semicircular filter strip 100 with the removable portion 400 now removed.

[0122] In one embodiment filter section 550 of conical filter tip 500 can be folded similar to a hand fan as shown in FIG. 10. In one embodiment filter section 550 of semicircular filter strip 100 can be spirally rolled as shown in FIG. 13.

[0123] In forming conical filter tip 500, as schematically indicating in FIG. 8, radial length 170 of filter strip 100 can be folded upon itself (such as by using perforation or fold lines 310 to assist in the folding and schematically indicated by zig zag arrow 312). Arc length 170 can be determined by the radius from radius of curvature of semicircular filter strip 100 to the middle of height 220 multiplied by the angle measurement in radians of radial length 170. Arc length 180 can be determined by the radius from radius of curvature of semicircular filter strip 100 to the middle of height 220 multiplied by the angle measurement in radians of radial length 180. Such arc lengths will give an average arc length between the bottom of height 220 to the top of height 220.

[0124] Radial length 170 can be placed between a users thumbs and forefingers and is folded alternatively (or in an undulating manner) toward radial length 180. The number of times that radial length 170 of filter strip 100 can be folded upon itself depends both on radial length 170, and the size of the folds (e.g., the distance between fold lines 310).

[0125] After the folding of radial length 170, radial length 170 and radial length 180 are then rolled upon themselves (schematically indicated by arrow 106) until filter tip 500 is formed as shown formed in FIG. 10.

Rolling Sheets or Cigarette Papers

[0126] FIGS. 11 and 12 show sheets or papers that can be used with filter tip 500 to make finished cigars or cigarettes.

[0127] FIG. 11 shows a carton 1300 of cigarette papers 600, 600′, 600″, etc. which can be used with one or more of the filter tips 500 to form a finished cigar or cigarette. FIG. 12 is a perspective view of a stack of smokable sheets which can be used with one or more of the filter tips.

[0128] Cigarette rolling papers can be stored and packaged in a cigarette rolling paper carton 1300 having a rectangular box-shaped base 1305 and dispensing opening 1320.

[0129] Sheet 600 can have a length consistent with conventional cigarette paper sheets, e.g., in the range of from about one to four inches. In a preferred embodiment sheet 600 can be about 2.75 inches by 1.5 inches, and 3 inches by 2 inches. It is, however, to be understood that these dimensions are provided for purposes of reference and illustration, and can be other than that specifically described.

[0130] Sheet 600 can include a section or strip 645 of adhesive, glue or moisture-activated gum disposed on a frontside sheet surface at a position adjacent a edge 640. Adhesive section 645 extends a distance from edge 640 towards edge 620. In a preferred embodiment, the adhesive section 645 has a width of approximately 3/16 inches, (e.g., extends away from the edge 640 approximately 3/16 inches), and is formed from a moisture-activated gum.

[0131] Moisture and flavors may be added (by methods known to one skilled in the art such as spraying a mist, brushing or dipping the sheets of flammable material into a vat of hydrant or flavor mixture, etc.) to sheets 600 etc.

[0132] In an example embodiment, sheet 600 has a length 620 of approximately 2.75 inches and a width 610 of approximately 1.5 inches, rolling strip 100 is approximately 0.75 inches wide 200 by 1.25 inches long 160. In another example embodiment, sheet 600 has a length 620 of approximately 3 inches and a width 610 of approximately 2 inches, rolling strip 100 is approximately 0.75 inches wide 200 by 1.75 inches long 160.

Hand Rolling a Finished Cigarette or Cigar

[0133] FIGS. 13-15 schematically indicate the steps of preparing a cigarette or cigar with filter tip 500.

[0134] It is desired that the height 200 of filter tip 500 be sufficient so that, when rolled to assist in forming the rolled cigarette or cigar, filter tip 500 provides a sufficient distance between a tip of the cigarette or cigar and the smoking material to prevent ones fingers or lips from being burned during holding or smoking the cigarette. In one embodiment filter tip 500 has a sufficient height 200 to assist or guide the user in rolling sheet 600 upon itself into a cylinder or cone.

[0135] As shown in FIGS. 13-15, sheet 600 can be rolled over filter tip 500. Sheet 600 can be a rectangular sheet of conventional cigarette paper, homogenized tobacco, and/or natural leaf tobacco.

[0136] Filter tip 500 (with a spiral filter section 550′ compared to a folded filter section 550) should be placed close to the longitudinal centerline of sheet 600 (FIG. 13) and sheet 600 is rolled or bent around an outside surface of filter tip 500 to form a U-shaped or V-shaped pouch extending longitudinally from side 630 to side 610.

[0137] During this step, filter tip 500 can act as a guide to assist the user in forming a generally U-shaped pouch not only along the section of sheet 600 that is placed into direct contact with the outside surface of filter tip 500. The ability to form a generally U-shaped pouch is desired as it increases the user's ability to form a cigarette having a substantially cylindrical or conical configuration.

[0138] Tobacco filler material 1150′ is placed within the formed pouch 625 between first end 510 of filter tip 500 and side 610 of sheet 600. Once the desired amount of tobacco filter material 1150′ is placed into pouch 625, the user uses filter tip 500 as a guide to roll side 620 of sheet 600 around both filter tip 500 and the volume of tobacco filler material 1150′.

[0139] Continuing in this manner, filter tip 500 assists the user in rolling sheet 600 in substantially cylindrical or conical form, by allowing user to roll side 640 over side 620 and use adhesive strip 645 to form a seal for the rolled cigarette or cigar. The step of rolling side 640 of sheet 600 around filter tip 500 and tobacco filler material 1150′ is continued so that the side 620 becomes tucked between the front 612 of sheet 600, on one side, and filter tip 500 and tobacco filler material 1150′, on an opposite side. A rear surface 614 of sheet 600 interfaces with and is rolled against the front 612 about filter tip 500 and tobacco filler material 1150′, and toward side 640 until only the adhesive section 645 remains exposed.

[0140] During the hand rolling process of rolling sheet 600, filter tip 500 acts as a guide that is used between the fingers of a user to assist in the formation of a finished cigarette or cigar. Optional adhesive strip 645 on sheet 600 can be activated by conventional means, e.g., if the adhesive section is a moisture-activated gum it is activated by licking, and rolling of the cigarette rolling paper is continued so that the adhesive section is sealed against an adjacent rear 614 to form a cigar or cigarette 1200 as shown in FIG. 15.

[0141] Using the above steps for the cylindrical filter tip 500, conical filter tip 500 can be used to make a cone 1100. FIG. 16 is a perspective view a cone 1100 for the consumption of smokable substances having sheet 600 of material comprised of tobacco, homogenized tobacco and/or natural leaf material such as plant leaves (e.g., banana, palm leaves, etc.) and the like rolled around conical filter tip 500. Sheet 600 forming cone 1100.

[0142] In various embodiments cone 1100 can be comprised of multiple sheets 600, 602, 604, 606, etc. Cone 1100 can be made to any desired length 650, and can have first end 1110, a second end 1120, an inner volume 1140. First end 1110 can have a width 1112, and second end 1120 can have a width 112. Width 1112 can be greater than width 1122. In various embodiments the ratio of the widths can be about 1.1, 1.2, 1.25, 1.3, 1.4, 1.5, 1.6. 1.75, 1.8, 1.9, 2.0, 2.25, 2.5, 2.75, 3.0, 3.5, 4.0, 4.5, 5.0, 6, 7, 8, 9, and 10. In various embodiments the ratio can be a range between any two of the above referenced ratios.

[0143] A conical filter tip 500 may be disposed within the first second end 1120 of cone 1100. Filter tip 500 can include filter section 550 and open section 570.
