July 4, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors Kaljura, Karl (London, GB); Richardson, John (London, GB); Blick, Kevin (London, GB), filed on July 17, 2012, was made available online on June 19, 2014 (see also British American Tobacco (investments) Limited).

The assignee for this patent application is British American Tobacco (investments) Limited.

Reporters obtained the following quote from the background information supplied by the inventors: "As used herein, the term 'smoking article' includes smokable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products (i.e. products in which flavour is generated from a smoking material by the application of heat without causing combustion of the material). Typically, smoking articles are provided with filters for removing constituents from the smoke.

"It can be desirable to introduce ventilating air into the smoke. Known ways of doing so involve providing ventilation holes in the outside of the filter. The ventilation holes can be provided relatively straightforwardly but have various disadvantages including, for example, that they are prone to being accidentally blocked by the user's fingers. It is also known to provide grooves in the filter for smoke or ventilating air flow. However, smoking articles including grooved filters can be complex and expensive to manufacture."

In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventors' summary information for this patent application: "The invention provides, in a first aspect, a smoking article comprising a source of smokable material, a filter, a first layer surrounding at least a part of the filter, a second layer surrounding at least a part of the first layer and one or more paths for ventilating air flow between the first and second layers, wherein a part of the first layer surrounds the source of smokable material and is for attaching the filter thereto.

"Thus, the invention can provide an effective and efficient way of including paths for ventilating air flow in a smoking article, namely between a first layer, which is also for attaching the filter to the source of smoking material, and a surrounding second layer.

"The invention provides, in a second aspect, a smoking article comprising a source of smokable material, a filter, a first layer surrounding at least a part of the filter, a second layer surrounding at least a part of the first layer and one or more paths for ventilating air flow between the first and second layers, wherein at least a part of the one or more paths is located further from an axis of the smoking article than any part of the filter or of the source of smokable material.

"At least a part of the first layer may comprise an irregular outer surface that defines, together with the second layer, the one or more paths. The one or more paths may have one or more air outlets located near to the end of the filter furthest from the source of smokable material. The one or more paths may have one or more air outlets into the filter. The first layer and/or the second layer may be formed from a sheet material.

"The invention provides, in a third aspect, a method of manufacturing a smoking article, the method comprising providing a source of smokable material, providing a filter, surrounding at least a part of the filter with a first layer, surrounding at least a part of the first layer with a second layer, and forming one or more paths for ventilating air flow between the first and second layers, wherein a part of the first layer surrounds the source of smokable material and is for attaching the filter thereto, or wherein at least a part of the one or more paths is located further from an axis of the smoking article than any part of the filter or of the source of smokable material.
