Abstract: A mouthpiece or filter element comprising a longitudinally extending hollow rod of filtering material having inner and outer surfaces, the inner surface defining at least one longitudinally extending channel which extends along the full length of the mouthpiece or filter element, wherein the distance between the inner and outer surfaces is 1 mm or less, wherein the filtering material of the mouthpiece or filter element comprises a plasticiser, wherein the amount of plasticiser present in the filtering material is less than 21.5%.

Abstract: A tobacco smoke filter or filter element comprising a stiff outer wrapper engaged around a downstream thermoformed core of tobacco smoke filtering material and a further core longitudinally aligned therewith; the downstream thermoformed core having a profiled outer surface which defines with the stiff outer wrapper at least one longitudinally extending channel which extends the length of the downstream core.

Abstract: There is disclosed a mouth piece, filter element or cooling element 100 comprising: a longitudinally extending core of filtering material 102; one or more channels 104 extending longitudinally from an end of the core 102; wherein the or each channel 104 has a non-circular transverse cross section which varies in the longitudinal direction by rotating about a longitudinal axis I of the mouth piece, filter element or cooling element 100.

Abstract: The present invention relates to smoking articles, for example electronic cigarettes (h referred to as “e-cigarettes”), and fluid reservoirs for use therewith or therein.

Abstract: A tobacco smoke filter or filter element including a longitudinally extending core of tobacco smoke filtering material of circumference 14 to 17 mm which includes a channel which extends longitudinally from an end of the core; wherein the core further includes a plasticiser in an amount of 17 to 19% by weight of the tobacco smoke filtering material.

Abstract: A mouthpiece for a smoking device is provided. The mouthpiece comprises a porous substrate. The porous surface comprises a wall having an outer surface having an outer cross-sectional shape and an inner surface having an inner cross-sectional shape. The inner surface defines a hollow interior space. A wall thickness is defined by the outer and inner surfaces. The porous substrate has a specific hardness of at least about 1.5 hardness % per weight (g) per length (mm) of the porous substrate. The porous substrate has a porosity of about 50% to about 70%. The inner and outer surfaces provide a wall thickness of about 20% to 60% of an area defined by the outer cross-sectional shape.

Abstract: A mouthpiece or filter element comprising a longitudinally extending hollow rod of filtering material having inner and outer surfaces, the inner surface defining at least one longitudinally extending channel which extends along the full length of the mouthpiece or filter element, wherein the distance between the inner and outer surfaces is 1 mm or less, wherein the filtering material of the mouthpiece or filter element comprises a plasticiser, wherein the amount of plasticiser present in the filtering material is less than 21.5%.

Abstract: A particulate material dispenser including a longitudinally extending body having a longitudinally extending base element; a tubular element extending longitudinally from the base element such that an inner wall of the tubular element defines a first cavity; a capping element which is distanced longitudinally from an end of the tubular element; a common outer wrapper which is engaged around the base element, the tubular element and the capping element, the inner wall of the common outer wrapper defining a second cavity between the tubular element and the capping element; and snuff within both the first cavity and the second cavity. The base element and/or the tubular element is porous.

Abstract: Processes for the manufacture of dispensers for an agent, for example, a therapeutic agent, for example a particulate therapeutic agent or a particulate foodstuff or snuff. The processes comprise the steps of continuously advancing, longitudinally, a flow of longitudinally extending dispensers and wrapping these dispensers by a common product wrapper. The dispensers comprise at least a base element (72), a cylindrical tubular element (73) with a cavity (74), a capping element (76) and a common outer wrapper (77).

Abstract: A tip for a smoking article such as a cigar is disclosed. The tip comprises a longitudinally extending element comprising a plurality of bicomponent fibers which define at least one channel extending longitudinally of the element.

Abstract: A method for assessing the acceptability of product filter rods, filters or filter elements which include a longitudinally extending core of filtering material including a longitudinal channel extending from an end of the core.

Abstract: The invention provides a method of producing a tobacco smoke filter or filter element comprising: • heat treating a continuously advancing longitudinally extending strand of material; • cooling the heat treated continuously advancing strand; and • forming a longitudinally extending outer layer of tobacco smoke filtering material around the continuously advancing strand, to form a continuously advancing rod comprising a longitudinally extending strand (1a) of material and a longitudinally extending outer layer (2a) of tobacco smoke filtering material engaged around the longitudinally extending strand (1a). An apparatus for carrying out the method, and products of the method, are also provided.
