Abstract: An electronic cigarette including a liquid supply, an air inlet, an inhalation port, and an atomizer. The liquid supply has a housing with a spiral container, having an outlet for directing a liquid held within the container out to the atomizer and at least one inlet sealed by a sealing agent to impede movement of the liquid. An air channel leads from the air inlet through the atomizer to the inhalation port for directing an aerosol generated at the atomizer to the inhalation port.

Abstract: A smoking article comprises a rod of smokable material circumscribed by a rod wrapper and a filter comprising at least one filter segment circumscribed by a filter wrapper. The rod of smokable material and the filter are attached to one another by tipping paper and the smoking article comprises a tear ribbon between the at least one filter segment and the tipping paper. The tear ribbon is affixed to at least one of the tipping paper and the filter wrapper.

Abstract: A filter for passing tobacco smoke or other gaseous material comprising two layers of material having a plurality of circuitous or serpentine passageways forming pathways through which tobacco smoke travels a distance greater than the length of the filter itself. The filter is constructed by coating the layers with an adhesive except in the areas forming the passageways so that when the two layers are fastened together, there are unobstructed paths through the layers of material. The combined layers are rolled into a cylindrical construct. In an alternative embodiment, one or more cavities are formed along the passageways.

Abstract: A filtering/heat-reduction smoking apparatus for various tobacco products. A convoluted passageway in the apparatus removes tar and other harmful chemicals and reduces the heat of the smoke thereby increasing the user's pleasure. Air intake holes also aid in reducing heat. The design requires the smoke to travel through a convoluted passageway many times greater than the length of the apparatus. The apparatus disassembles quickly and easily for cleaning.

Abstract: An improved tobacco smoke filter is characterized by longitudinally continuous grooves running from end-to-end in the peripheral surface of a smoke-impervious filter plug wrap. Smoke-impervious tipping surrounds the plug wrap to seal the grooves except for small ventilation holes in the tipping which permit communication between the grooves and the ambient air. In a preferred embodiment, the grooves are restricted toward the mouth end of the filter and the degree of restriction determines the direction of air and smoke flow in the grooves. The grooves are each preferably formed as two longitudinal sections of different cross-section. Apparatus and method for manufacturing the filter are disclosed.

Abstract: A tobacco product such as a cigarette having a tobacco column within a combustible wrap and a filter plug located at one end of the tobacco column to filter constituents of the mainstream smoke. The filter plug is disposed within a layer of plug wrap which preferably is nonporous and an outer tipping wrap surrounds the plug wrap. A plurality of grooves or depressions formed along the filter plug provide for a secondary flow of air to the mouth of the smoker. An access opening communicating secondary air to each groove is defined by a plurality of perforations located in one or more rows or bands around the outer tipping paper. Depressions located along axes parallel to the axis of the filter member or disposed in a helical pattern may be used. In a second form of the invention, the access opening communicating secondary air to each groove is defined by an annular opening between individual portions of the outer tipping paper.

Abstract: There is disclosed apparatus and method for making helical center-cored smokers' filters from pipe cleaners or the like in which a guide for winding the pipe cleaner includes a thin walled metal tube with an inside diameter slightly smaller than the pipe cleaner and a wire affixed to the outside of the tube in the shape of a helix. The pipe cleaner is put in the tube for a fraction of its length and is then wound along the guide around the tube and itself by the use of a transparent plastic hollow cylinder slipped over the tube and with a pipe cleaner engaging notch in one end. An opening in the cylinder allows a fully wound pipe cleaner to be held in place while the guide is rotated and disengaged from it after which the wound pipe cleaner filter is pushed out of the cylinder and removed.

Abstract: The filtration route of tobacco smoke is increased by coiling a length of plastic tube filled with activated charcoal to form a coiled configuration similar to a coiled spring and placed between the conventional cellulose filter and the tobacco charge by using cigarette wrapping paper to form an assembled cigarette. While the tobacco charge remains close to the cellulose filter, the smoke from the burning tobacco charge starts its filtering route much farther away from the cellulose filter and as the smoke passes through the longer filtration route it is cooled by ambient air and completely filtered of all harmful tars. The coil configuration may also be constructed by casting the activated charcoal configuration as a core by utilizing a mold fabricated in two half sections. The coiled core is sprayed with a sealant to render it impervious to liquids and air and then inserted into a section of thin wall tube the length of the coiled core to protect the core from damage in handling.

Abstract: A filter element for a smoking article, such as a cigarette, comprises a generally cylindrical body having at least one helical groove in its peripheral surface and closely wrapped in a material pervious to vapor-phase constituents of the smoke, whereby such constituents are removed by diffusion thereof through said material during passage of the smoke along the groove. The body may be wholly or in part of a filter material capable of removing particulate-phase constituents from the smoke during its passage through the element. Suitably the groove extends from the upstream end face of the body to a point short of the downstream end face, where it opens into a space separated from the downstream end by an ungrooved portion of smoke-filter material. One or more faces of the groove and/or said upstream end face may be partially or wholly sealed against penetration of smoke into the body.

Abstract: A mouthpiece for cigarettes comprising a tubular exterior cylinder of substantially circular cross-section obtained by extrusion molding of synthetic resin and having at least one deflecting wall extending inwardly from the inner surface of said exterior cylinder, and the juncture of said deflecting wall with the inner surface of said exterior cylinder being formed in a helix about the central longitudinal axis of said exterior cylinder.
