  • Patent number: 10701977
    Abstract: The present invention is a method for vaporizing concentrate that will substantially eliminate general or localized burning of concentrate during the vaporization process and a device adapted for carrying out said method. The vaporization method is based on heating concentrate that has been absorbed into a frit, preferably fitted glass. Fritted glass is characterized by open-pore interstices that allow free passage of fluid through the frit. It is commonly used as a filtering element, particularly in high-temperature applications. It was discovered that concentrate placed in contact with fitted glass is absorbed through capillary action. Although room temperature concentrate may not readily seep fully into fritted glass, as concentrate is heated its viscosity is reduced such that it is readily absorbed by the fitted glass.

  • Patent number: 10314335
    Abstract: An electronic cigarette has a vaporizer to produce vapor to be delivered to its mouth end. The vaporizer includes a tube having inlet and outlet ends. A porous matrix containing a vaporizable liquid, extends around the tube. Wicking fibers extend through side openings in the tube and are configured to wick the vaporizable liquid from the porous matrix into the tube, and electrical heater coil is powered by a battery to vaporize liquid on the wicking fibers in the tube, so that vapor is supplied along the tube end when the user draws on mouth end. The wicking fibers are wrapped around outer surface of the tube so as to contact and receive the vaporizable liquid by capillary action from the matrix. The wrapping of the wicking fibers may be in a spiral pattern in the same or opposite directions along the tube.

  • Patent number: 10314330
    Abstract: A smoking article is provided, having opposed lighting and mouth ends, and including a mouth end portion at the mouth end. A tobacco portion is between the lighting end and the mouth end portion. An aerosol-generation system is between the lighting end and the tobacco portion. The aerosol-generation system includes a heat generation portion, comprising an elongate fluted member actuated by ignition of the lighting end. The fluted member defines grooves extending longitudinally between opposed first and second ends, with the first end being at the lighting end and the grooves being equidistantly spaced apart about the fluted member. Each groove has a maximum depth. The depth maxima of the grooves define a circle having a radius. The maximum depth of each groove is no more than the radius of the circle. A heat generation apparatus for an aerosol-generation system of a smoking article is also provided.

  • Patent number: 10292431
    Abstract: Pellet substrates configured for use with a vapor delivery device to vaporize and deliver an aerosol to a user include porous, substantially inert activated carbon and activated alumina pellets that have generally spherical, semi-spherical and/or rounded shapes. The pellet substrates are formed by mixing the pellets together with a liquid solution of an aerosol former admixed with flavoring and/or nicotine, tobacco powder, or tobacco extract such that the liquid solution is absorbed into and/or adsorbed onto the porous structure of the pellets with or without the addition of heat. The pellets may be coated with an inert dry powder, such as calcium carbonate, to better adhere the liquid solution to the porous surfaces of the pellets. Alternatively, or in addition, the pellets may be coated with a liquid solution of a cellulose gum, such as sodium carboxymethylcellulose, and distilled water to reduce fracturing, cracking, chipping and dusting of the pellet substrates.
