  • Patent number: 5829453
    Abstract: A low-density filler material for cigarettes from either a low-density tobacco composition or an extruded grain or starch composition. The low-density tobacco composition and a method of making the low-density tobacco composition by extruding a mixture of tobacco and flour or tobacco and starch under conditions whereby the solvent in the extruded mixture flashes into vapor upon release from the extrusion head. The low-density tobacco composition is formed without the aid of an added binder. The low-density flour or starch material and a method of making it by extruding flour or starch with a filler material such as calcium carbonate under conditions whereby the solvent in the extruded mixture flashes into vapor upon extrusion through the orifice die. The extruded composition can then be cut and used in place of cut tobacco filler.

  • Patent number: 5829452
    Abstract: A container, which may or may not be in the form of a cylinder conforming generally to the shape of a cigar, having a wall thickness and constitution which permits water vapor to escape therethrough, but which will not permit water droplets or palpable moisture to pass therethrough and subsequently over-wet the material to be humidified, such as cigars. The container is adapted to house a quantity of highly absorbent material, such as acrylamide potassium or sodium acrylate copolymer, cross-linked. End caps may be used as desired, including end caps with apertures therein to permit an accelerated rate of humidification by allowing more water vapor to escape the interior of the container than is allowed by ordinary osmosis through the walls of the container.

  • Patent number: 5819752
    Abstract: A mouthpiece for smoking instruments which is structured to be anatomically correct, in that it is structurally compatible with the mouth parts of a user when the mouthpiece is situated in the user's mouth to one side thereof. The mouthpiece is a laterally asymmetrical structure which conforms to the shape of the side of the mouth. The tip is acutely angled in relation to the mouthpiece axis which lateral asymmetry locates the tip so that it does not interferingly affront the tongue and cheek thereby increasing comfort and teeth feel and the port of the tip is directed toward the tongue cavity thereby making inhalation easier and more efficient. The mouthpiece is vertically symmetrical so that by simply inverting the mouthpiece, it can be placed comfortably at either side of a user's mouth. The mouthpiece is preferred to include a groove adjacent the end for interfacingly receiving with the tips of the smoker's teeth.
