Cigar Or Cigarette Patents (Class 131/360)
  • Patent number: 9955734
    Abstract: The present invention relates to an electronic cigarette for convenient injection of cigarette liquid, manufacturing method thereof, and a method for injecting cigarette liquid into the electronic cigarette. A liquid injection hole is opened at a bottom of a liquid storage cup of the electronic cigarette, and the liquid injection hole is sealed by a sealing element which is self-closing once an injection device has been pulled out from the sealing element. The components of the electronic cigarette of the present invention can be assembled together first prior to the injection of cigarette liquid. Therefore, the problem of leakage and contamination of cigarette liquid during the manufacture of existing electronic cigarettes can be overcome. The automated injection of cigarette liquid can be carried out at places where the electronic cigarettes are sold.

  • Patent number: 9936732
    Abstract: An electronic cigarette for preventing mutual rotation of an atomizing assembly and a battery assembly is provided. The battery assembly and the atomizing assembly of the electronic cigarette are connected by magnetic attraction. The atomizer connecting end is provided with a retaining member with a corner angle; the battery connecting end is provided with an accommodating cavity which allows the atomizer connecting end to be inserted therein; and the accommodating cavity is provided with a guiding retaining groove allowing the retaining member to be inserted therein. When the battery assembly and the atomizing assembly are connected by magnetic attraction, the mutual rotation can be interfered and restrained as the connection section has the corner angles, and the atomizing assembly and the battery assembly can not rotate with respect to one another.

  • Patent number: 9801417
    Abstract: An exemplary atomizer for an electronic cigarette includes an atomizing sleeve, a liquid chamber sealed in the atomizing sleeve, and an atomizing assembly arranged at a bottom end of the sleeve. The atomizing sleeve defines an air outlet at a top end thereof. The atomizing assembly includes a hollow fixing holder, a transmission component, a seal cover, an elastic element, an air pipe, and a heating component. The seal cover is movable with the transmission component between a first position where a liquid passage is formed between the seal cover and the fixing holder, and a second position where the liquid passage is closed. The elastic element is configured for storing energy when the liquid passage is open, and for driving the transmission component to move downwards and bringing the seal cover to move downwards to close the liquid passage.

    Abstract: A method of making composite nanoscale particles comprising subjecting a starting material to laser energy so as to form a vapor and condensing the vapor so as to form the composite nanoscale particles, wherein said composite nanoscale particles comprise a first metal and/or a first metal oxide incorporated in nanoscale particles of an oxide of a second metal, the first metal being different than the second metal. The starting material can comprise first and second metals or compounds of the first and second metals. The composite nanoscale particles can be formed in a reaction chamber wherein a temperature gradient is provided. The atmosphere in the chamber can be an inert atmosphere comprising argon or a reactive atmosphere comprising oxygen. The composite nanoscale particles are useful for low-temperature and near-ambient temperature catalysis.

  • Patent number: 8616220
    Abstract: A tobacco product is formed by perforated cigar or shell, the shell comprising a sheet of material with an intermediate sheet, the sheet comprising tobacco leaves and/or homogenized tobacco paper. The cigar or shell is packaged for shipment to an end user or consumer. The cigar or shell remains in the rolled, shaped tube form inside the package. After the cigar or shell is removed from the package, a consumer can fill the cigar or shell with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the cigar or shell to moisturize same. The liquid can include flavoring.

  • Patent number: 8578944
    Abstract: A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls (e.g. moistened tobacco leaves) and/or homogenized sheet tobacco about a slit mandrel to form a shaped tube. The shaped tube is then packaged for shipment to an end user or consumer. The shaped tube remains in the rolled, shaped tube form inside the package. After the shaped tube is removed from the package, a consumer can fill the tube with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the sheet or to the finished tube to moisturize same. The liquid can include flavoring. The tubes are unfilled when packaged and sent to a consumer/end user in tube form so that they have a “memory” that helps hold a tubular cigar shape after they are filled with selected tobacco fill material.

  • Patent number: 8573230
    Abstract: A smoking article having a cylindrical tube of smokable material having an outer wrapper, a concentric rod of smokable material coaxially positioned within the cylindrical tube of a smokable material, and an inner wrapper separating the cylindrical tube and the concentric rod. A filter attaches to the tobacco rod with an annular film positioned between the filter and the tobacco rod. The annular film increases the resistance-to-draw of the cylindrical tube during smoking.

  • Patent number: 8555897
    Abstract: A tobacco smoking mixture including an ammonia-release compound adapted to be formed into a lit-end cigarette is provided. The ammonia-release compound is incorporated in or on tobacco cut filler in an amount effective to reduce the cytotoxicity, and/or selective smoke constituents of cigarette smoke. Exemplary ammonia-release compounds include ammonium acetate, ammonium hydroxide, hexammine cobalt (III) chloride, hexammine cobalt (III) acetate, and combinations thereof. The ammonia-release compounds can release ammonia at temperatures between about 60° C. and about 400° C. Ammonia-release compounds can be combined with additives, such as glycerine, cobalt acetate, copper (II) acetate, zinc acetate, other metal salts or combinations thereof, to further reduce the cytotoxicity of cigarette smoke.
