  • Patent number: 9788569
    Abstract: A novel cigar is provided with an elongated cigar puller device which extends into the interior of the cigar. By removing the cigar puller from the cigar, the tobacco fill material of the cigar is disrupted so as to improve the draw of the cigar. Once the cigar puller is removed from the tobacco fill material, a flavorant and/or aromatic can be infused into the less dense tobacco fill material which is provided upon the removal of the cigar puller.

  • Patent number: 9204667
    Abstract: A smokeless tobacco composition configured for insertion into the mouth of a user is provided. The smokeless tobacco composition includes a tobacco material and a polysaccharide filler component such as polydextrose. A process for preparing a smokeless tobacco composition pastille configured for insertion into the mouth of a user is also provided. The process includes mixing a tobacco material with a binder and a polysaccharide filler component to form a smokeless tobacco mixture, injection molding the smokeless tobacco mixture, and cooling the smokeless tobacco mixture to form a solidified smokeless tobacco composition pastille. The mixing step can include forming a dry blend of the tobacco, filler, and binder components, and combining the dry blend with a viscous liquid component. The injection-molded pastille can provide a dissolvable and lightly chewable product.

  • Patent number: 8505549
    Abstract: The present invention is a holder and method for using a holder that works with a hand rolled cigarette. A hollow tubular member is utilized having a first end that the user breathes from, and a second end that holds the hand-rolled cigarette. The cigarette is tightly rolled about an elongate steel rod or other stiff member having a diameter that can pass through the hollow tubular member, such that the rod protrudes from the cigarette far enough to be easily grasped by the user. The user inserts the rod through the holder until it passes out the first end, thereby wedging the attached cigarette into the second end of the holder. The second end of the holder preferably has internal threads, and the rod is twisted by the user to further engage the threads by the cigarette end to reliably affix the cigarette to the holder. The rod is then removed, leaving the cigarette firmly in the holder.

    Abstract: A tobacco product consists of a preportioned tobacco strand (10) surrounded by a preformed tubular cigarette paper wrapper (11; 17). The tobacco strand is formed of individual tobacco fibers which are interconnected to each other by a binding agent to form a dimensionally stable tobacco strand. The binding agent and the fibers are each smokable but the outer surface of the tubular dimensionally stable tobacco strand is air pervious so that the strand as such is not directly smokable. The dimensionally stable strand (10) is inserted into the preformed tubular cigarette paper wrapper (11) to form a smokable cigarette. The one end of the strand is tapered for easier insertion of the strand into the preformed cigarette paper wrapper.

  • Patent number: 5024242
    Abstract: Relatively fragile components for cigarette-like smoking articles are wrapped with an overwrap by bringing an exposed axial surface portion of the component into resilient contact with the overwrap, and by then rolling the component about its longidudinal axis, again by resiliently contacting the component. Smoking articles including the foregoing components as the distal component and at least one other proximal component are made by supplying a pair of distal components with their distal ends facing one another and pushed up against an interposed stop. The overwrap is slit parallel to the stop just prior to application to the distal components. After overwrapping, the distal components are reoriented so that their distal ends face away from one another. A pair of proximal components is then placed between the distal components, and each proximal component is joined to the adjacent distal component by a tipping overwrap.

  • Patent number: 4972855
    Abstract: A shredded tobacco leaf pellet is composed of tobacco leaf shreds bound together with a nicotine-non-absorptive thermoplastic binder while retaining air permeability. The pellet is produced by mixing tobacco leaf shreds and a nicotine-non-absorptive thermoplastic binder, forming the resultant mixture into a desired shape while retaining air permeability, and then subjecting the thus-formed mixture to a heat treatment. A cigarette-like snuff is composed of at least one shredded tobacco leaf pellet of the above-described type and an outer envelope surrounding the pellet therein.

  • Patent number: 4893637
    Abstract: Apparatus and methods are described for forming a composite member for use in making a smoking article. The apparatus comprises a forming device that comprises (a) an elongate structure having a curved inner surface that tapers from a larger proximal end to a smaller distal end, the proximal end of the structure being adapted to receive a support member and a layer of material which are fed simultaneously into the device, the tapering inward curved inner surface causing the edges of the fibrous layer to bend around the inner support member, and (b) a curved forming surface that causes a first edge of the material to fold over the support member while permitting the second edge to pass by the forming surface, the curved inner surface of the device further tapering to the distal end causing the second edge of the material to fold over the support member proximate to the first edge.

  • Patent number: 4832056
    Abstract: A hand operated device for applying cigarette paper to a preformed tobacco rod comprises a forming roller arranged to rotate the rod about its longitudinal axis, a mechanical applicator for applying a pregummed sheet of cigarette paper to the rod as the rod is rotated about its axis, wherein the forming roller is provided along its length with a pair of circumferential helical grooves of opposite chirality, there being further provided a manually operable spigot device adapted to cooperate with the grooves and constrained to travel linearly parallel to the axis of the roller whereby manual movement of the spigot in either linear direction rotates the roller in a constant angular direction.

  • Patent number: 4632131
    Abstract: An extruded, coherent, multistrand, tobacco-containing, generally cylindrical smoking article and a process for making it are disclosed. The smoking article contains a plurality of strands that are adhered to one another so as to form passageways between the strands, the passageways extending generally along the longitude of the smoking article. The configuration of the strands and passageways provides sufficient heat transfer area and/or residence time for the smoke drawn by a smoker to cool to an acceptable level.

  • Patent number: 4605013
    Abstract: Circumferentially extending recesses in the peripheral surface of a rotating suction wheel are filled with tobacco shreds which are delivered in the form of a narrow stream by a pneumatic conveyor having a narrow tobacco propelling channel extending radially of the suction wheel and receiving the shreds of the stream in a current of compressed air. The surplus of shreds is removed by the current and/or by a trimming device which is installed in the interior of the pneumatic conveyor, and such surplus is recirculated through the distributor of a cigarette rod making machine and back into the pneumatic conveyor. The batches are used to form the interrupted core of a composite tobacco filler wherein the core is surrounded by a tubular envelope containing a different blend of tobacco.

  • Patent number: 4595024
    Abstract: A cigarette, having a tobacco rod consisting of at least two segments. The segment toward the filter end of the tobacco rod has a density at least 20% greater than the fire-end segment. The density differential may be combined with a nicotine differential, such that the fire-end segment has a higher nicotine content than does the filter-end segment. This configuration alters the nicotine delivery of the invention, providing a nicotine delivery either uniform during the last half of the cigarette or at levels reduced from those seen during the first few puffs.
